ITEM 1.

BUSINESS

OVERVIEW

MEDNAX is a leading provider of physician services including newborn, maternal-fetal, pediatric subspecialties, and anesthesia care. At December 31, 2012, our national network comprised over 2,100 affiliated physicians, including approximately 1,000 physicians who provide neonatal clinical care, in 34 states and Puerto Rico, primarily within hospital-based neonatal intensive care units (“NICUs”), to babies born prematurely or with medical complications. We have over 200 affiliated physicians who provide maternal-fetal care to expectant mothers experiencing complicated pregnancies and obstetrical hospitalist services in many areas where our affiliated neonatal physicians practice. Our network includes other pediatric subspecialists, including approximately 120 physicians providing pediatric cardiology care, 100 physicians providing pediatric intensive care, 60 physicians providing hospital-based pediatric care and 15 physicians providing pediatric surgical care. In addition, we have over 625 physicians who provide anesthesia care to patients in connection with surgical and other procedures as well as pain management.

MEDNAX, Inc. was incorporated in Florida in 2007 and is the successor to Pediatrix Medical Group, Inc., which was incorporated in Florida in 1979. Our principal executive offices are located at 1301 Concord Terrace, Sunrise, Florida 33323, and our telephone number is (954) 384-0175.

Our Physician Specialties

The following discussion describes our physician specialties and the care that we provide:

•

Neonatal Care. We provide clinical care to babies born prematurely or with complications within specific units at hospitals, primarily NICUs, through a team of experienced neonatal physician subspecialists (“neonatologists”), neonatal nurse practitioners and other pediatric clinicians. Neonatologists are board-certified or eligible-to-apply-for-certification physicians who have extensive education and training for the care of babies born prematurely or with complications that require complex medical treatment. Neonatal nurse practitioners are registered nurses who have advanced training and education in managing the healthcare needs of newborns, infants and their families.

•

Maternal-Fetal Care. We provide outpatient and inpatient clinical care to expectant mothers and their unborn babies through our affiliated maternal-fetal medicine subspecialists, obstetricians and other clinicians, such as maternal-fetal nurse practitioners, certified nurse mid-wives, ultrasonographers and genetic counselors. Maternal-fetal medicine subspecialists are board-certified or eligible-to-apply-for-certification obstetricians who have extensive education and training for the treatment of high-risk expectant mothers and their fetuses. Our affiliated maternal-fetal medicine subspecialists practice primarily in metropolitan areas where we have affiliated neonatologists to provide coordinated care for women with complicated pregnancies whose babies are often admitted to a NICU upon delivery.

•

Pediatric Cardiology Care. We provide inpatient and outpatient pediatric cardiology care of the fetus, infant, child, and adolescent patient with congenital heart defects and acquired heart disease as well as adults with congenital heart defects through our affiliated pediatric cardiologist subspecialists and other

clinicians such as pediatric nurse practitioners, echocardiographers and other diagnostic technicians, and exercise physiologists. Pediatric cardiologists are board-certified pediatricians who have additional education and training in congenital heart defects and pediatric acquired heart disorders.

•

Other Pediatric Subspecialty Care. Our network includes pediatric intensivists, who are hospital-based pediatricians with additional education and training in caring for critically ill or injured children and adolescents, pediatric hospitalists, who are hospital-based pediatricians specializing in inpatient care and management of acutely ill children and pediatric surgeons, who provide specialized care for patients ranging from newborns to adolescents, for all problems or conditions affecting children that require surgical intervention, and often have particular expertise in the areas of neonatal, prenatal, trauma, and pediatric oncology. Our affiliated physicians also provide clinical services in other areas of hospitals, particularly in the labor and delivery area, newborn nursery and pediatric department, where immediate accessibility to specialized care may be critical.

•

Anesthesia Care. We provide anesthesia care through a team of experienced physician anesthesiologists, certified registered nurse anesthetists (“CRNAs”) and anesthesia assistants (“AAs”). Using the care team approach, anesthesiologists supervise CRNAs and AAs allowing us to provide high quality, cost efficient and service oriented anesthesia care to our patients. Our anesthesiologists are board-certified, or eligible-to-apply-for-certification, physicians who are responsible for administering anesthesia to relieve pain and for managing vital life functions, including breathing, heart rhythm and blood pressure, during surgery. After surgery, they maintain the patient in a comfortable state during recovery and are involved in the provision of critical care medicine in the intensive care unit in urban and community hospitals and surgical centers.

•

Anesthesia Subspecialty Care. In addition to their board certification in anesthesiology, many of our anesthesiologists have completed fellowships in subspecialties such as obstetrical, critical care, cardiac and pediatric anesthesia.

•

Pain Management. We also provide acute and chronic pain management services. Postoperative acute pain management is often initiated in the hospital recovery room and may continue for the remainder of the hospital stay. Chronic pain services are offered through outpatient medical offices, hospital clinics and ambulatory service centers. These facilities are staffed with board-certified anesthesiologists or neurologists, who are also board-certified or eligible-to-apply-for-certification in pain medicine, who provide patients with a comprehensive evaluation and treatment plan for their pain. These facilities provide a full spectrum of care ranging from medical management of pain through minimally invasive interventional procedures.

As part of our ongoing commitment to improving patient care through evidence-based medicine, we also conduct clinical research, monitor clinical outcomes and implement clinical quality initiatives with a view to improving patient outcomes, shortening the length of hospital stays and reducing long-term health system costs. We believe that referring and collaborating physicians, hospitals, third-party payors and patients all benefit from our clinical research, education and quality initiatives.

Demand for Our Services

Neonatal Medicine. Of the approximately four million births in the United States annually, we estimate that approximately 13% require NICU admissions. Numerous institutions conduct research to identify potential causes of premature birth and medical complications that often require NICU admissions. Some common contributing factors include the presence of hypertension or diabetes in the mother, lack of prenatal care, complications during pregnancy, drug and alcohol abuse and smoking or poor nutritional habits during pregnancy. Babies admitted to NICUs typically have an illness or condition that requires the care of a neonatologist. Babies who are born prematurely or have a low birth weight often require neonatal intensive care services because of increased risk for medical complications. We believe obstetricians generally prefer to perform deliveries at hospitals that provide a full complement of labor and delivery services, including a NICU

staffed by board-certified or eligible-to-apply-for-certification neonatologists. Because obstetrics is a significant source of hospital admissions, hospital administrators have responded to these demands by establishing NICUs and contracting with independent neonatology group practices, such as our affiliated professional contractors, to staff and manage these units. As a result, NICUs within the United States tend to be concentrated in hospitals with higher volumes of births. There are approximately 5,000 board-certified neonatologists in the United States.

Maternal-Fetal Medicine. Expectant mothers with pregnancy complications often seek or are referred by their obstetricians to maternal-fetal medicine subspecialists. These subspecialists provide inpatient and outpatient care to women with conditions such as diabetes, heart disease, hypertension, multiple gestation, recurrent miscarriage, family history of genetic diseases, suspected fetal birth defects, and other complications during their pregnancies. We believe that improved maternal-fetal care has a positive impact on neonatal outcomes. Data on neonatal outcomes demonstrates that, in general, the likelihood of mortality or an adverse condition or outcome (referred to as “morbidity”) is reduced the longer a baby remains in the womb. There are approximately 1,900 board-certified maternal-fetal medicine subspecialists in the United States.

Pediatric Cardiology Medicine. Pediatric cardiologists provide inpatient and outpatient cardiology care of the fetus, infant, child, and adolescent with congenital heart defects and acquired heart disease, as well as of adults with congenital heart defects. We estimate that approximately one in every 120 babies is born with some form of heart defect. With advancements in care, there are approximately one million adults in the United States today living with congenital heart disease. There are approximately 2,100 board-certified pediatric cardiologists in the United States.

Other Pediatric Subspecialty Medicine. Other areas of pediatric subspecialty medicine are closely associated with maternal-fetal-newborn medical care. For example, pediatric intensivists are subspecialists who care for critically ill or injured children and adolescents in pediatric intensive care units (“PICUs”). There are approximately 1,600 board-certified pediatric intensivists in the United States. As another example, pediatric hospitalists are pediatricians who provide care in many hospital areas, including labor and delivery and the newborn nursery. In addition, pediatric surgeons provide specialized care for patients ranging from newborns to adolescents, for all problems or conditions affecting children that require surgical intervention, and often have particular expertise in the areas of neonatal, prenatal, trauma, and pediatric oncology. There are approximately 800 board-certified pediatric surgeons in the United States.

Anesthesia Medicine. An estimated 46 million inpatient procedures and 35 million ambulatory procedures are performed annually in the United States. Anesthesiologists generally provide or participate in the administration of anesthetics in these procedures. According to the U.S. Census Bureau, the U.S. population continues to expand and the fastest-growing segment of the population consists of individuals over the age of 65. The growth in population and, in particular the age 65 or greater segment, has resulted in an increase in demand for surgical services and a correlating increase in demand for anesthesia services. The growth of ambulatory surgical centers and expansion of office-based procedures has also contributed to the demand for anesthesia services. There are approximately 47,000 anesthesiologists in the United States.

Pain Management. According to the American Academy of Pain Medicine, more than 76 million people suffer from pain and 15% of those who suffer from pain will consult with a pain specialist. As the population ages, we believe the number of people suffering from acute or chronic pain will continue to increase. Lifestyle also plays an important part in the demand for pain management services. We believe that the combination of the growing population of people who suffer from pain, the lifestyle expectations of this population and the ability for patients to seek out a pain specialist without having to be referred by a physician will increase the demand for pain management services.

Hospital-Based Care. Hospitals generally must provide cost-effective, quality care in order to enhance their reputations within their communities and desirability to patients, referring and collaborating physicians and third-party payors. In an effort to improve outcomes and manage costs, hospitals typically employ or contract with

physician specialists to provide specialized care in many hospital-based units or settings. Hospitals traditionally staff these units or settings through affiliations with local physician groups or independent practitioners. However, management of these units and settings presents significant operational challenges, including variable admissions rates, increased operating costs, complex reimbursement systems and other administrative burdens. As a result, some hospitals choose to contract with physician organizations that have the clinical quality initiatives, information and reimbursement systems and management expertise required to effectively and efficiently operate these units and settings in the current healthcare environment. Demand for hospital-based physician services, including neonatology and anesthesiology, is determined by a national market in which qualified physicians with advanced training compete for hospital contracts.

Practice Administration. Administrative demands and cost containment pressures from a number of sources, principally commercial and government payors, make it increasingly difficult for physicians to effectively manage patient care, remain current on the latest procedures and efficiently administer non-clinical activities. As a result, we believe that physicians remain receptive to being affiliated with larger organizations that reduce administrative burdens, achieve economies of scale and provide value-added clinical research, education and quality initiatives. By relieving many of the burdens associated with the management of a subspecialty group practice, we believe that our practice administration services permit our affiliated physicians to focus on providing quality patient care and thereby contribute to improving patient outcomes, ensuring appropriate length of hospital stays and reducing long-term health system costs. In addition, our national network of affiliated physician practices, modeled around a traditional group practice structure, is managed by a non-clinical professional management team with proven abilities to achieve significant operating efficiencies in providing administrative support systems, interacting with physicians, hospitals and third-party payors, managing information systems and technologies, and complying with laws and regulations.

Our Business Strategy

Our business objective is to enhance our position as a leading provider of physician services. The key elements of our strategy to achieve this objective are:

•

Build upon core competencies. We have developed significant administrative expertise relating to neonatal, maternal-fetal and other pediatric subspecialty services, as well as, more recently, to our anesthesiology practices. We have also facilitated the development of a clinical approach to the practice of medicine among our affiliated physicians through a clinical data warehouse that includes research, education and quality initiatives intended to advance the practice of neonatology, maternal-fetal, pediatric cardiology medicine and pediatric intensive care, improve the quality of care provided to acutely ill newborns and expectant mothers with pregnancy complications and reduce long-term health system costs. We have begun the development and implementation of a clinical data warehouse throughout our anesthesiology practices by collecting patient information throughout the continuum of care. The growth of this program will allow us to establish quality benchmarks for clinical outcomes, patient satisfaction and perioperative efficiencies across our anesthesiology practices.

•

Promote same-unit and organic growth. We seek opportunities for increasing revenue from our hospital- and office-based operations. For example, our affiliated hospital-based neonatal, maternal-fetal and other pediatric physicians are well situated to, and, in some cases, provide physician services in other departments, such as newborn nurseries, or in situations where immediate accessibility to specialized obstetric and pediatric care may be critical. In addition, our hospital-based physicians are actively pursuing an organic growth strategy that involves working with our hospital partners to develop integrated services programs for which we become a multi-specialty provider of solutions within the maternal-fetal, newborn, pediatric continuum of care. An integrated program results in a broader offering of care across our specialties and permits the extension of our service lines in our markets. We are successfully executing this organic growth strategy and market partnership in several metropolitan areas and intend to continue this growth initiative in the future. In addition, we market our capabilities to obstetricians, pediatricians and family physicians to attract referrals to our hospital-

based units and our office-based practices. We also market the services of our affiliated physicians to other hospitals to attract neonatology transport admissions. In addition, we pursue new contractual arrangements with hospitals where we do not currently provide physician services. We are developing similar opportunities with our affiliated anesthesiologists.

•

Acquire physician practice groups. We continue to seek to expand our operations by acquiring established physician practices in our specialties which include neonatology, maternal-fetal medicine, pediatric cardiology and anesthesiology. We also pursue complementary pediatric subspecialty physician groups, such as pediatric intensivists, pediatric hospitalists and pediatric surgeons. During 2012, we added 16 physician groups to our national network through acquisitions consisting of eight anesthesiology practices, two maternal-fetal medicine practices, two pediatric cardiology practices, one neonatal practice, and three other pediatric subspecialty practices. The three other pediatric subspecialty practices acquired consist of one pediatric intensivist practice, one pediatric hospitalist program and one pediatric surgery practice.

•

Strengthen relationships with our partners. By managing many of the operational challenges associated with physician practices, encouraging clinical research, education and quality initiatives, and promoting timely intervention by our physicians, we believe that our business model is focused on improving the quality of care delivered to patients, promoting the appropriate length of their hospital stays and optimizing efficient use of health system resources. We believe that referring and collaborating physicians, hospitals, third-party payors and patients all benefit to the extent that we are successful in implementing our business model.

OUR PHYSICIAN SERVICES

Neonatal Care

We provide neonatal care to babies born prematurely or with complications within specific hospital units, primarily NICUs, through our network of over 1,000 affiliated neonatal physicians and other related clinical professionals who staff and manage clinical activities at more than 330 NICUs in 34 states and Puerto Rico. We partner with our hospital clients in an effort to enhance the quality of care delivered to premature and sick babies. Some of the nation’s largest and most prestigious hospitals, both not-for-profit and for-profit institutions, retain us to staff and manage their NICUs. Our affiliated neonatologists generally provide 24-hours-a-day, seven-days-a-week coverage in NICUs, support the local referring physician community and are available for consultation in other hospital departments. Our hospital partners benefit from our experience in managing complex intensive care units. Our neonatal physicians interact with colleagues across the country through an internal communications system to draw upon their collective expertise in managing challenging patient-care issues. Our neonatal physicians also work collaboratively with maternal-fetal medicine subspecialists to coordinate care of mothers experiencing complicated pregnancies and their fetuses. We also employ or contract with neonatal nurse practitioners, who work with our affiliated physicians in providing medical care.

Maternal-Fetal Care

We provide outpatient and inpatient maternal-fetal care to expectant mothers with complicated pregnancies and their fetuses through our network of over 200 affiliated physicians and other related clinical professionals who provide maternal-fetal medical care. Our affiliated neonatologists practice with maternal-fetal medicine subspecialists to provide coordinated care for expectant mothers with complicated pregnancies whose babies are often admitted to the NICU upon delivery. We believe continuity of treatment from mother and developing fetus during the pregnancy to the newborn upon delivery has improved the clinical outcomes of our patients.

Pediatric Cardiology Care

Our pediatric cardiology practice consists of approximately 120 affiliated physicians and other related clinical professionals who provide specialized cardiac care to the fetus, neonatal and pediatric patients with

congenital and acquired heart disorders, as well as adults with congenital heart defects, through scheduled office visits, hospital rounds and immediate consultation in emergency situations. Our affiliated cardiologists work collaboratively with neonatologists and maternal-fetal medicine subspecialists to provide a coordinated continuum of care.

Other Pediatric Subspecialty Care

Our network includes other pediatric subspecialists such as pediatric intensivists, pediatric hospitalists and pediatric surgeons. In addition, our affiliated physicians seek to provide support services in other areas of hospitals, particularly in the labor and delivery area, nursery and pediatric department, where immediate accessibility to specialized care may be critical. Our experience and expertise in maternal-fetal-neonatal medicine has led to our involvement in these other areas.

•

Pediatric Intensive Care. We have approximately 100 affiliated physicians who provide clinical care for critically ill or injured children and adolescents. They staff and manage PICUs at over 35 hospitals.

•

Pediatric Hospitalists. We have over 60 affiliated hospital-based physicians who provide clinical care to acutely ill children at more than 20 hospitals.

•

Pediatric Surgery. We have 15 affiliated physicians in this subspecialty including pediatric urologists, pediatric plastic and craniofacial surgeons and general and thoracic pediatric surgeons who provide specialized care for patients ranging from newborns to adolescents, for all problems or conditions affecting children that require surgical intervention. Areas of particular expertise include management of neonatal and congenital anomalies, prenatal counseling, trauma management, pediatric oncology, gastrointestinal surgery, as well as common pediatric surgical conditions.

•

Other Newborn and Pediatric Care. Because our affiliated physicians and advanced nurse practitioners generally provide hospital-based coverage, they are situated to provide highly specialized care to address medical needs that may arise during a baby’s hospitalization. For example, as part of our ongoing efforts to support and partner with hospitals and the local referring physician community, our affiliated neonatologists, pediatric hospitalists and advanced nurse practitioners provide in-hospital nursery care to newborns through our newborn nursery program. This program is made available for babies during their hospital stay, which in the case of healthy babies typically consists of evaluation and observation, following which they are referred, and their hospital records are provided, to their pediatricians or family practitioners for follow-up care.

•

Newborn Hearing Screening Program. Our affiliated physicians also oversee our newborn hearing screening program. Since we launched this program in 1994, we believe that we have become the largest provider of newborn hearing screening services in the United States. In 2012, we screened over 650,000 babies for potential hearing loss at more than 330 hospitals across the nation. Over 40 states either require newborns to be screened for potential hearing loss before being discharged from the hospital or require that parents be offered the opportunity to submit their newborns to hearing screens. We contract or coordinate with hospitals to provide hearing screening services.

Anesthesia Care

We provide anesthesia care at hospitals, ambulatory surgery centers, and office-based practices with our over 625 affiliated anesthesiologists. Following the “care team” model, our physicians work with both practice and hospital employed anesthetists. As an integral part of the surgical team, our anesthesiologists support the surgeons by providing medical care before, during and after surgery so that surgeons may concentrate on the applicable surgery. Our anesthesiologists provide this care by evaluating the patient and consulting with the surgical team before surgery, providing pain control and support of life functions during surgery, supervising care after surgery and discharging the patient from the recovery unit. They also support other departments within the hospital such as labor and delivery, sedation for imaging, and the hospital’s emergency room by providing

services as appropriate to patients requiring immediate care. In addition, our physicians provide anesthesia care at ambulatory surgical centers and office-based practices for procedures that require some level of anesthesia.

Pain Management

Our physicians and physician assistants provide pain management services in outpatient centers. Our physicians are board-certified in anesthesiology or neurology and board-certified, or eligible-to-apply-for-certification, in pain medicine. This advanced training and education expands treatment options available for both acute and chronic pain sufferers. The physicians develop treatment plans specific to the patients’ individual needs that include interventional techniques such as trigger point and facet injections, pain pumps, nerve stimulators, radiofrequency ablation and catheters as well as medication management.

CLINICAL RESEARCH, EDUCATION AND QUALITY

As part of our patient focus and ongoing commitment to improving patient care through evidenced-based medicine, we engage in clinical research, continuous quality improvement, and education initiatives. We discover, understand, and teach healthcare practices that enhance the abilities of clinicians to deliver quality care, thereby contributing to better patient outcomes and reduced long-term health system costs. Our investment in these initiatives benefits our patients, clinicians, referring and collaborating physicians, hospital partners and third-party payors. We believe that these initiatives help us, among other things, to enhance the value of our services, attract new and retain existing clinicians, improve clinical operations and enhance practice communication.

•

Clinical Research. We conduct clinical research to discover ways to improve clinical care for our patients. We share our discoveries throughout the medical community through submissions to peer-reviewed literature.

•

We completed several new multi-center clinical trials in 2012. For example, in neonatal medicine, we completed one of the largest trials ever in neonatal nutrition, entitled How Illness and Nutritional Support Influence Amino Acid and Acylcarnitine Profiles in Premature Neonates. This trial enrolled over 1,000 patients and the data is currently being analyzed. Initial review suggests that the results of this trial will have a substantial impact upon the approach to premature infant feeding. New recommendations about the use of parenteral nutrition, breast milk, and formula for the low birth weight infant are likely to be forthcoming from this study. As a subset of this investigation, we undertook a detailed metabolic evaluation of breast milk and neonatal premature formulas that has revealed previously unknown details about the nutritional composition of these products in infant feeding. A second trial that examined the causes of mortality in the NICU, evaluating more than 600 cases, has also been completed and will soon be analyzed. New insights into preventative approaches to care are expected to result from this investigation.

•

We also continue to publish research based on data from our clinical information systems, our clinical trials, and from our individual practice efforts. In 2012, more than 75 papers were published as a result of this research addressing many different areas of neonatal, maternal-fetal, and pediatric cardiology care. Our clinical data warehouse has also remained a major reference source at a national level, and has been highlighted in several publications as well as in numerous national forums and presentations during 2012. Our clinical data warehouse now has accumulated clinical information from more than 800,000 infants and more than 16 million patient days, and is frequently used by universities and government agencies.

•

Continuous Quality Improvement. As part of our dedication to improving quality across our affiliated practices, we provide our clinicians with powerful information resources. Our physicians have access to accumulated data and robust software tools that enable them to compare their practices to our national practice network across a variety of activity and outcome metrics. From these comparisons, our physicians can identify areas for improvement, and then systematically monitor, study, learn and

implement change. We believe that our initiatives in continuous quality improvement have contributed to better patient care. One of our efforts in neonatal care resulted in a significant reduction in the duration and frequency of antibiotic utilization in the NICU. Other ongoing projects include: optimization of weight gain among very low birth weight infants; focus on increasing the use of breast milk; and reduction in the rates of necrotizing enterocolitis, or death of intestinal tissue, and chronic lung disease. Our “100,000 Babies Campaign” is focused on the delivery of care in NICUs generally with improved clinical outcomes as a result. One of the current efforts in this project has been directed at reducing catheter-related blood stream infections in neonates, and has resulted in a continuing reduction in infection rates. Continuous quality improvement initiatives are underway for our other physician specialties. For example, in anesthesia care, several internal programs are being evaluated to provide standardized clinical outcome reporting, trend analysis and threshold performance. In addition, our anesthesiologists are leading several hospital sponsored patient safety initiatives. Our anesthesiologists are also evaluating our role in creating high performance surgical teams through innovative programs such as simulation centers and reenactment capabilities. Some of our prior continuous quality initiatives have resulted in published research papers. In March 2012, we published a second volume on continuous quality improvement issues entitled Evidence-Based Neonatal Pharmacotherapy in Clinics in Perinatology as a follow-up to our 2010 issue on neonatal quality improvement.

•

Continuing Medical Education. We also make extensive physician continuing medical education and continuing nursing education resources available to our affiliated clinicians in an effort to ensure that they have access to current treatment methodologies. As an accredited provider for clinicians, we offer live continuing medical education through what we believe is one of the premier conferences in neonatal medicine—NEO: The Conference for Neonatology. In 2012, we also held our Specialty Review in Neonatology course, which provides a broad review of the entire subspecialty of neonatal medicine. These two meetings, each held annually, had more than 1,100 attendees this past February. In addition to live educational opportunities, we also offer online education through “Pediatrix University—A University Without Walls^®,” an interactive educational website, which we continue to enhance with live presentations that are recorded at our various in person conferences.

•

Patient Safety Organization. We have established a federally listed Patient Safety Organization (“PSO”), the mission of which is to improve the quality and safety of care rendered by our clinical providers through the collection and analysis of quality data. Our PSO encourages the development and dissemination of information regarding best practices and supports our dedication to clinical research and continuous quality improvement.

We believe that these initiatives have been enhanced by our integrated national presence together with our clinical and management information systems, which are an integral component of our clinical research and education activities. See “Our Information Systems.”

OUR PRACTICE ADMINISTRATION

We provide multiple administrative services to support the practice of medicine by our affiliated physicians and improve operating efficiencies of our affiliated practice groups.

•

Unit Management. A senior physician practicing medicine in each NICU, PICU, maternal-fetal, pediatric cardiology, anesthesia and other subspecialty practice that we manage acts as the medical director for that unit or practice. Each medical director is responsible for the overall management of his or her unit or practice, including staffing and scheduling, quality of care, professional discipline, utilization review, coordinating physician recruitment, and monitoring the financial success within the unit or practice. Medical directors also serve as a liaison with hospital administration, other physicians and the community.

•

Staffing and Scheduling. We assist with staffing and scheduling physicians and advanced practice nurses within the units and practices that we manage. For example, each NICU is staffed by at least one

specialist on site or available on call. For our affiliated anesthesia physicians, CRNAs and AAs, we employ an operational system that assists with their staffing and scheduling. We are responsible for the salaries and benefits paid and provided to our affiliated physicians and practitioners. In addition, we employ, compensate and manage all non-medical personnel for our affiliated physician groups.

•

Recruiting and Credentialing. We have significant experience in locating, qualifying, recruiting and retaining experienced physicians. We maintain an extensive nationwide database of maternal-fetal, neonatal and other pediatric subspecialty physicians and are continuing to develop such a database for anesthesiologists. Our medical directors and physician management play a central role in the recruiting and interviewing process before candidates are introduced to other practice group physicians and hospital administrators. We verify the credentials, licenses and references of all prospective affiliated physician candidates. In addition to our database of physicians, we recruit nationally through trade advertising, referrals from our affiliated physicians and attendance at conferences.

•

Billing, Collection and Reimbursement. We assume responsibility for contracting with third-party payors for all of our affiliated physicians. We are responsible for billing, collection and reimbursement for services rendered by our affiliated neonatal, maternal-fetal, pediatric subspecialty and anesthesia physicians. In all instances, however, we do not assume responsibility for charges relating to services provided by hospitals or other physicians with whom we collaborate. Such charges are separately billed and collected by the hospitals or other physicians. We provide our affiliated physicians with a training curriculum that emphasizes detailed documentation of and proper coding protocol for all procedures performed and services provided, and we provide comprehensive internal auditing processes, all of which are designed to achieve appropriate coding, billing and collection of revenue for physician services. Generally, our billing and collection operations are conducted from our business offices located across the United States and in Puerto Rico as well as our corporate offices.

•

Risk Management and Other Services. We maintain a risk management program focused on reducing risk, including the identification and communication of potential risk areas to our medical affairs staff. We maintain professional liability coverage for our national group of affiliated healthcare professionals. Through our risk management and medical affairs staff, we conduct risk management programs for loss prevention and early intervention in order to prevent or minimize professional liability claims. In addition, we provide a multi-faceted compliance program that is designed to assist our affiliated practice groups in complying with increasingly complex laws and regulations. We also provide management information systems, facilities management, legal support, marketing support and other services to our affiliated physicians and affiliated practice groups.

OUR INFORMATION SYSTEMS

We maintain several information systems to support our day-to-day operations and ongoing clinical research and business analysis. Since inception, our clinical information systems have accumulated clinical information from more than 16 million daily progress records relating to over 800,000 discharged patients.

•

BabySteps^®. BabySteps is an electronic health record system used by our affiliated neonatal physicians to record clinical progress notes electronically and provides a decision tree to assist them in certain situations with the selection of appropriate billing codes. BabySteps is certified as an Electronic Health Record (“EHR”) module through the Certification Commission for Health Information Technology (“CCHIT^®”), an Office of the National Coordinator—Authorized Testing and Certification Body (“ONC-ATCB”), in accordance with the applicable hospital certification criteria adopted by the Secretary of Health and Human Services that support the Stage 1 meaningful use measures required to qualify eligible providers and hospitals under the American Recovery and Reinvestment Act (“ARRA”).

•

Clinical Data Warehouse. BabySteps enables our affiliated practices to capture a consistent set of information about the patients we treat. We transfer information from our electronic health records in

BabySteps to what we call our “clinical data warehouse.” With comprehensive reporting tools, our physicians are able to use this information to benchmark outcomes, enhance clinical decision-making and advance best practices at the bedside. Using a variety of clinical performance markers, a de-identified version of the data warehouse also helps us track drug interactions, link treatments to outcomes and identify opportunities to enhance patient outcomes. Our clinical data warehouse also helps us to identify prospective clinical trials and continuous quality improvement initiatives.

•

Quantum. We have begun to implement a quality initiative tool, Quantum Clinical Navigation Systems (“Quantum”) throughout our American Anesthesiology physician practices. Quantum is a real time data collection tool that follows each patient through the continuum of care. Quantifiable metrics assess patient satisfaction, efficiency, physician performance and quality indicators. The data is then stored, analyzed and reported to physicians and hospitals. Our clinicians use the data, along with evidence-based medicine, to develop and implement best practices and standard operating procedures, all with the goal of improving outcomes and efficiency and ensuring patient satisfaction.

•

Nextgen^®. We have licensed the Nextgen Electronic Medical Record (“EMR”) and Electronic Patient Management (“EPM”) system for our office-based maternal-fetal and pediatric cardiology physicians to record clinical documentation related to their patients and manage the revenue cycle for our office-based practices. This system has the ability to provide benefits to our office-based practices that are similar to what BabySteps provides to our neonatology practices, including decision trees to assist physicians with the selection of appropriate billing codes, promotion of consistent documentation, and data for research and education. We are continuing the process of implementing EMR and EPM in all of our office-based maternal-fetal and pediatric cardiology practices. The 5.6 version of our Nextgen system has been certified as a Complete Electronic Health Record system by CCHIT, in accordance with the applicable certification criteria adopted by the Secretary of Health and Human Services that support the Stage 1 meaningful use measures required to qualify eligible providers and hospitals for funding under the ARRA.

•

Pediatrix University^®. In addition to providing continuing education, our Pediatrix University also functions as a “virtual doctors’ lounge,” enabling physicians around the country to discuss difficult or unusual cases with one another. It also provides a rich source of ongoing medical education in neonatology and maternal-fetal medicine.

Our management information systems are also an integral element of the billing and reimbursement process. We maintain systems that provide for electronic data interchange with payors that accept electronic submission, including electronic claims submission, insurance benefits verification and claims processing and remittance advice, which enable us to track numerous and diverse third-party payor relationships and payment methods. Our information systems provide scalability and flexibility as payor groups upgrade their payment and reimbursement systems. We continually seek improvements to our systems to expedite the overall process, streamlining information gathering from our clinical systems through to improving efficiencies in the reimbursement process.

We maintain additional information systems designed to improve operating efficiencies of our affiliated practice groups, reduce physicians’ paperwork requirements and facilitate interaction among our affiliated physicians and their colleagues regarding patient care issues. Following the acquisition of a physician practice group, we implement systematic procedures to improve the acquired group’s operating and financial performance. One of our first steps is to convert a newly acquired group to our broad-based management information system. We also maintain a database management system to assist our business development and recruiting departments to identify potential practice group acquisitions and physician candidates.

RELATIONSHIPS WITH OUR PARTNERS

Our business model, which has been influenced by the direct contact and daily interaction that our affiliated physicians have with their patients, emphasizes a patient-focused clinical approach that addresses the needs of

our various “partners,” including hospitals, third-party payors, referring and collaborating physicians, affiliated physicians and, most importantly, our patients. Our relationships with all our partners are important to our continued success.

Hospitals

Our relationships with our hospital partners are critical to our operations. We have been retained by over 350 hospitals to staff and manage clinical activities within specific hospital-based units. Our affiliated physicians are important components of obstetric, pediatric and surgical services provided at hospitals. Our hospital-based focus enhances our relationships with hospitals and creates opportunities for our affiliated physicians to provide patient care in other areas of the hospital. For example, our physicians may provide care in emergency rooms, nurseries and other departments where access to specialized obstetric, pediatric and anesthesia care may be critical. Because hospitals control access to their units and operating rooms through the awarding of contracts and hospital privileges, we must maintain good relationships with our hospital partners. Our hospital partners benefit from our expertise in managing critical care units and other settings staffed with physician specialists, including managing variable admission rates, operating costs, complex reimbursement systems and other administrative burdens. We also work with our hospital partners to enhance their reputation and market our services to referring physicians, an important source of hospital admissions, within the communities served by those hospitals. In addition, our affiliated physicians work with our hospital partners to develop integrated services programs for solutions within the maternal-fetal, newborn, pediatric continuum of care. Integrated programs provide our hospital partners and us with incremental growth and result in a broader spectrum of care across our specialties and permit us to extend our patient service lines into our existing markets.

Under our contracts with hospitals, we have the responsibility to manage, in many cases exclusively, the provision of physician services for hospital-based units, such as NICUs, and other hospital settings. We typically are responsible for billing patients and third-party payors for services rendered by our affiliated physicians separately from other related charges billed by the hospital or other physicians to the same payors. Some of our hospital contracts require hospitals to pay us administrative fees. Some contracts provide for fees if the hospital does not generate sufficient patient volume in order to guarantee that we receive a specified minimum revenue level. We also receive fees from hospitals for administrative services performed by our affiliated physicians providing medical director services at the hospital. Administrative fees accounted for approximately 7% of our net patient service revenue during 2012. Some of our contracts with hospitals require us to indemnify them and their affiliates for losses resulting from the negligence of our affiliated physicians. Our hospital contracts typically have terms of one to three years which can be terminated without cause by either party upon prior written notice, and renew automatically for additional terms of one to three years unless terminated early by any party. While we have in most cases been able to renew these arrangements, hospitals may cancel or not renew our arrangements, or reduce or eliminate our administrative fees in the future.

Third-Party Payors

Our relationships with government-sponsored plans, including Medicaid and Medicare, managed care organizations and commercial health insurance payors are vital to our business. We seek to maintain professional working relationships with our third-party payors, streamline the administrative process of billing and collection, and assist our patients and their families in understanding their health insurance coverage and any balances due for co-payments, co-insurance, deductibles or out-of-network benefit limitations. In addition, through our quality initiatives and continuing research and education efforts, we have sought to enhance clinical care provided to patients, which we believe benefits third-party payors by contributing to improved patient outcomes and reduced long-term health system costs.

We receive compensation for professional services provided by our affiliated physicians to patients based upon rates for specific services provided, principally from third-party payors. Our billed charges are substantially the same for all parties in a particular geographic area, regardless of the party responsible for paying the bill for

our services. A significant portion of our net patient service revenue is received from government-sponsored plans, principally state Medicaid programs. Medicaid programs pay for medical and health-related services for certain individuals and families with low incomes and resources and are jointly funded by the federal government and state governments. Medicaid programs can be either standard fee-for-service payment programs or managed care programs in which states have contracted with health insurance companies to run local or state-wide health plans with features similar to health maintenance organizations. Our compensation rates under standard Medicaid programs are established by state governments and are not negotiated. Rates under Medicaid managed care programs are negotiated but are similar to rates established under standard Medicaid programs. Although Medicaid rates vary across the states, these rates are generally much lower in comparison to private-sector health plan rates. In November 2012, the Centers for Medicare & Medicaid Services (“CMS”) adopted a rule under the “Patient Protection and Affordable Care Act,” (the “Affordable Care Act” formerly referred to as the “Healthcare Reform Act”) that would allow physicians who provide eligible primary care services to generally be paid at the Medicare reimbursement rates in effect in calendar years 2013 and 2014 instead of state-established Medicaid reimbursement rates. Generally, state Medicaid reimbursement rates are lower than federally-established Medicare rates. See Item 1A. Risk Factors—“State budgetary constraints could have an adverse effect on our reimbursement from Medicaid programs.”

Medicare is a health insurance program primarily for individuals 65 years of age and older, certain younger people with disabilities and people with end-stage renal disease. The program is provided without regard to income or assets and offers beneficiaries different ways to obtain their medical benefits. The most common option selected today by Medicare beneficiaries is the traditional fee-for-service payment system. The other options include managed care, preferred provider organizations, private fee-for-service and specialty plans. Medicare compensation rates are generally much lower in comparison to private-sector health plans. Because we provide anesthesia services to a wide array of patients, including Medicare beneficiaries, a portion of our patients’ services are reimbursed by Medicare.

In order to participate in government programs, we and our affiliated practices must comply with stringent and often complex enrollment and reimbursement requirements. Different states also impose differing standards for their Medicaid programs. See “Government Regulation—Government Reimbursement Requirements.”

We also receive compensation pursuant to contracts with commercial payors that offer a wide variety of health insurance products, such as health maintenance organizations, preferred provider organizations and exclusive provider organizations that are subject to various state laws and regulations, as well as self-insured organizations subject to federal Employee Retirement Income Security Act (“ERISA”) requirements. We seek to secure mutually agreeable contracts with payors that enable our affiliated physicians to be listed as in-network participants within the payors’ provider networks. We generally contract with commercial payors through our affiliated professional contractors. Subject to applicable laws and regulations, the terms, conditions and compensation rates of our contracts with commercial third-party payors are negotiated and often vary widely across markets and among payors. In some cases, we contract with organizations that establish and maintain provider networks and then rent or lease such networks to the actual payor. Our contracts with commercial payors typically provide for discounted fee-for-service arrangements and grant each party the right to terminate the contracts without cause upon prior written notice. In addition, these contracts generally give commercial payors the right to audit our billings and related reimbursements for professional and other services provided by or through our affiliated physicians.

If we do not have a contractual relationship with a health insurance payor, we generally bill the payor our full billed charges. If payment is less than billed charges, we bill the balance to the patient, subject to state and federal laws regulating such billing. Although we maintain standard billing and collections procedures with appropriate discounts for prompt payment, we also provide discounts in certain hardship situations where patients and their families do not have financial resources necessary to pay the amount due for services rendered. Any amounts written-off related to private-pay patients are based on the specific facts and circumstances related to each individual patient account.

Referring and Collaborating Physicians

Our relationships with our referring and collaborating physicians are critical to our success. Our affiliated physicians seek to establish and maintain professional relationships with referring physicians in the communities where they practice. Because patient volumes at our NICUs are based in part on referrals from other physicians, particularly obstetricians, it is important that we are responsive to the needs of referring physicians in the communities in which we operate. We believe that our community presence, through our hospital coverage and outpatient clinics, assists referring obstetricians, office-based pediatricians and family physicians with their practices. Our affiliated physicians are able to provide comprehensive maternal-fetal, newborn and pediatric subspecialty care to patients using the latest advances in methodologies, supporting the local referring physician community with 24-hours-a-day, seven-days-a-week on-site or on-call coverage.

Our affiliated anesthesiologists seek to establish and maintain professional relationships with collaborating physicians, such as surgeons, and other healthcare providers. Our affiliated anesthesiologists play an important role for surgeons because they provide medical care to the patient throughout the surgical experience. This care includes evaluation of the patient prior to surgery, consultations with the surgical team, providing pain control and support of life functions during surgery and supervising care following surgery through the discharge of the patient from the recovery unit. Accordingly, our affiliated anesthesiologists are focused on delivering quality services to enhance the reputation and satisfaction of collaborating surgeons.

Affiliated Physicians and Practice Groups

Our relationships with our affiliated physicians are important. Our affiliated physicians are organized in traditional practice group structures. In accordance with applicable state laws, our affiliated practice groups are responsible for the provision of medical care to patients. Our affiliated practice groups are separate legal entities organized under state law as professional associations, corporations and partnerships, which we sometimes refer to as “our affiliated professional contractors.” Each of our affiliated professional contractors is owned by a licensed physician affiliated with the Company through employment or another contractual relationship. Our national infrastructure enables more effective and efficient sharing of new discoveries and clinical outcomes data, including implementation of best demonstrated processes, and affords access to our sophisticated information systems, and clinical research and education.

Our affiliated professional contractors employ or contract with physicians to provide clinical services in certain states and Puerto Rico. In most of our affiliated practice groups, each physician has entered into an employment agreement with us or one of our affiliated professional contractors providing for a base salary and incentive bonus eligibility and typically having a term of three to five years. We are typically responsible for billing patients and third-party payors for services rendered by our affiliated physicians and, with respect to services provided in a hospital, separately from other charges billed by hospitals to the same payors. Each physician must hold a valid license to practice medicine in the state in which he or she provides patient care and must become a member of the medical staff, with appropriate privileges, at each hospital at which he or she practices. Substantially all the physicians employed by us or our affiliated professional contractors have agreed not to compete within a specified geographic area for a certain period after termination of employment. Although we believe that the non-competition covenants of our affiliated physicians are reasonable in scope and duration and therefore enforceable under applicable state laws, we cannot predict whether a court or arbitration panel would enforce these covenants. Our hospital contracts also typically require that we and the physicians performing services maintain minimum levels of professional and general liability insurance. We negotiate those policies and contract and pay the premiums for such insurance on behalf of the physicians.

Each of our affiliated professional contractors has entered into a comprehensive management agreement with a subsidiary of MEDNAX, Inc. as manager. These agreements are long-term in nature, and in most cases permanent, subject only to a right of termination by the manager (except in the case of gross negligence, fraud or illegal acts of the manager). Under the terms of these management agreements, the manager is typically paid for

its services based on the performance of the applicable practice group. See “Government Regulation—Fee Splitting; Corporate Practice of Medicine.”

COMPETITION

Competition in our business is generally based upon a number of factors, including reputation, experience and level of care and our affiliated physicians’ ability to provide cost-effective, quality clinical care. The nature of competition for our hospital-based practices, such as neonatology and anesthesia care, differs significantly from competition for our office-based practices. Our hospital-based practices compete nationally with other health services companies and physician groups for hospital contracts and qualified physicians. In some instances, our hospital-based physicians also compete on a regional or local basis. For example, our neonatologists compete for referrals from local physicians and transports from surrounding hospitals. Our office-based practices, such as maternal-fetal medicine and pediatric cardiology, compete for patients with office-based practices in those subspecialties.

Because our operations consist primarily of physician services provided within hospital-based units, we compete with others for contracts with hospitals to provide services. We also compete with hospitals themselves to provide such services. Hospitals may employ neonatologists or anesthesiologists directly or contract with other physician groups to provide services either on an exclusive or non-exclusive basis. A hospital not otherwise competing with us may begin to do so by opening a new NICU or operating facility, expanding the capacity of an existing NICU, adding operating room suites or, in the case of neonatal services, upgrading the level of its existing NICU. If the hospital chooses to do so, it may award the contract to operate the relevant facility to a competing group or company. Because hospitals control access to their NICUs and operating rooms by awarding contracts and hospital privileges, we must maintain good relationships with our hospital partners. Our contracts with hospitals generally provide that they may be terminated without cause upon prior written notice.

The healthcare industry is highly competitive. Companies in other segments of the industry as well as healthcare-focused and other private equity firms, some of which have financial and other resources greater than ours, may become competitors in providing neonatal, maternal-fetal, other pediatric subspecialty care or anesthesia services.

GOVERNMENT REGULATION

The healthcare industry is governed by a framework of federal and state laws, rules and regulations that are extensive and complex and for which, in many cases, the industry has the benefit of only limited judicial and regulatory interpretation. If we or one of our affiliated practice groups is found to have violated these laws, rules or regulations, our business, financial condition and results of operations could be materially adversely affected. Moreover, the Affordable Care Act signed into law in March 2010 contains numerous provisions that are reshaping the United States healthcare delivery system, and healthcare reform continues to attract significant legislative interest, regulatory activity, new approaches, legal challenges and public attention that create uncertainty and the potential for additional changes. Healthcare reform implementation, additional legislation or regulations, and other changes in government policy or regulation may affect our reimbursement, restrict our existing operations, limit the expansion of our business or impose additional compliance requirements and costs, any of which could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock. See Item 1A. Risk Factors—“The Affordable Care Act may have a significant effect on our business.”

Licensing and Certification

Each state imposes licensing requirements on individual physicians and clinical professionals, and on facilities operated or utilized by healthcare companies like us. Many states require regulatory approval, including certificates of need, before establishing certain types of healthcare facilities, offering certain services or

expending amounts in excess of statutory thresholds for healthcare equipment, facilities or programs. We and our affiliated physicians are also required to meet applicable Medicaid provider requirements under state laws and regulations and Medicare provider requirements under federal law and regulations.

Fee Splitting; Corporate Practice of Medicine

Many states have laws that prohibit business corporations, such as MDX, from practicing medicine, employing physicians to practice medicine, exercising control over medical decisions by physicians, or engaging in certain arrangements, such as fee splitting, with physicians. In light of these restrictions, we operate by maintaining long-term management contracts through our subsidiaries with affiliated professional contractors, which employ or contract with physicians to provide physician professional services. Under these arrangements, our manager subsidiaries perform only non-medical administrative services, do not represent that they offer medical services and do not exercise influence or control over the practice of medicine by the physicians employed by the affiliated professional contractors. In states where fee splitting with a business corporation or manager is prohibited, the fees that are received from the affiliated professional contractors have been established on a basis that we believe complies with applicable laws. Although the relevant laws in these states have been subject to limited judicial and regulatory interpretation, we believe that we are in compliance with applicable state laws in relation to the corporate practice of medicine and fee splitting. However, regulatory authorities or other parties, including our affiliated physicians, may assert that, despite these arrangements, we or our manager subsidiaries are engaged in the corporate practice of medicine or that the contractual arrangements with the affiliated professional contractors constitute unlawful fee splitting, in which case we could be subject to administrative, civil or criminal remedies or penalties, the contracts could be found legally invalid and unenforceable, in whole or in part, or we could be required to restructure our contractual arrangements with our affiliated professional contractors.

Fraud and Abuse Provisions

Existing federal laws governing Medicaid, Medicare and other federal healthcare programs (the “FHC Programs”), as well as similar state laws, impose a variety of fraud and abuse prohibitions on healthcare companies like us. These laws are interpreted broadly and enforced aggressively by multiple government agencies, including the Office of Inspector General of the Department of Health and Human Services, the Department of Justice (the “DOJ”) and various state authorities. In addition, in the Deficit Reduction Act of 2005, Congress established a Medicaid Integrity Program to enhance federal and state efforts to detect Medicaid fraud, waste and abuse and provide financial incentives for states to enact their own false claims legislation as an additional enforcement tool against Medicaid fraud and abuse. Since then, a growing number of states have enacted healthcare fraud and abuse legislation.

The fraud and abuse laws include extensive federal and state regulations applicable to our financial relationships with hospitals, referring physicians and other healthcare entities. In particular, the federal anti-kickback statute prohibits the offer, payment, solicitation or receipt of any remuneration in return for either referring Medicaid, Medicare or other FHC Program business, or purchasing, leasing, ordering, or arranging for or recommending any service or item for which payment may be made by an FHC Program. In addition, federal physician self-referral legislation, commonly known as the “Stark Law,” prohibits a physician from ordering certain designated health services reimbursable by Medicare from an entity with which the physician has a prohibited financial relationship. These laws are broadly worded and, in the case of the anti-kickback statute, have been broadly interpreted by federal courts, and potentially subject many healthcare business arrangements to government investigation and prosecution, which can be costly and time consuming.

Violations of these laws are punishable by substantial penalties, including monetary fines, civil penalties, administrative remedies, criminal sanctions (in the case of the anti-kickback statute), exclusion from participation in FHC Programs and forfeiture of amounts collected in violation of such laws, any of which could have an adverse effect on our business and results of operations. Many of the states in which we operate also have similar

anti-kickback and self-referral laws which are applicable to our government and non-government business and which also authorize substantial penalties for violations.

There are a variety of other types of federal and state fraud and abuse laws, including laws authorizing the imposition of criminal, civil and administrative penalties for filing false or fraudulent claims for reimbursement with government healthcare programs. These laws include the civil False Claims Act (“FCA”), which prohibits the submitting of or causing to be submitted false claims to the federal government or federal government programs, including Medicaid, Medicare, the TRICARE program for military dependents and retirees, and the Federal Employees Health Benefits Program. Substantial civil fines and multiple damages, along with other remedies, can be imposed for violating the FCA. Furthermore, proving a violation of the FCA requires only that the government show that the individual or company that submitted or caused to be submitted an allegedly false claim acted in “reckless disregard” of the truth or falsity of the claim, notwithstanding that there may have been no intent to defraud the government program and no actual knowledge that the claim was false (which typically are required to be shown to sustain a criminal conviction). The FCA also applies to the improper retention of known overpayments and includes “whistleblower” provisions that permit private citizens to sue a claimant on behalf of the government and thereby share in the amounts recovered under the law and to receive additional remedies. In recent years, many cases have been brought against healthcare companies by such “whistleblowers,” which have resulted in judgments or, more often, settlements involving substantial payments to the government by the companies involved. It is anticipated that the number of such actions against healthcare companies will continue to increase with the enactment of a growing number of state false claims acts and certain amendments to the FCA recently enacted by Congress and enhanced government enforcement.

In addition, federal and state agencies that administer healthcare programs have at their disposal statutes, commonly known as “civil money penalty laws,” that authorize substantial administrative fines and exclusion from government programs in cases where an individual or company that filed a false claim, or caused a false claim to be filed, knew or should have known that the claim was false or fraudulent. As under the FCA, it often is not necessary for the agency to show that the claimant had actual knowledge that the claim was false or fraudulent in order to impose these penalties.

The civil and administrative false claims statutes are being applied in an increasingly broader range of circumstances. For example, government authorities have asserted that claiming reimbursement for services that fail to meet applicable quality standards may, under certain circumstances, violate these statutes. Government authorities also often take the position, now with support from recent amendments to the FCA, that claims for services that were induced by kickbacks, Stark Law violations or other illicit marketing schemes are fraudulent and, therefore, violate the false claims statutes. Many of the laws and regulations referenced above can be used in conjunction with each other.

If we or our affiliated professional contractors were excluded from any government-sponsored healthcare programs, not only would we be prohibited from submitting claims for reimbursement under such programs, but we also would be unable to contract with other healthcare providers, such as hospitals, to provide services to them. It could also adversely affect our or our affiliated professional contractors’ ability to contract with, or to obtain payment from, non-governmental payors.

Although we intend to conduct our business in compliance with all applicable federal and state fraud and abuse laws, many of the laws and regulations applicable to us, including those relating to billing and those relating to financial relationships with physicians and hospitals, are broadly worded and may be interpreted or applied by prosecutorial, regulatory or judicial authorities in ways that we cannot predict. Accordingly, we cannot assure you that our arrangements or business practices will not be subject to government scrutiny or be alleged or found to violate applicable fraud and abuse laws. Moreover, the standards of business conduct expected of healthcare companies under these laws and regulations have become more stringent in recent years, even in instances where there has been no change in statutory or regulatory language. If there is a determination

by government authorities that we have not complied with any of these laws and regulations, our business, financial condition and results of operations could be materially adversely affected. See “Government Investigations.”

Government Reimbursement Requirements

In order to participate in the various state Medicaid programs and in the Medicare program, we and our affiliated practices must comply with stringent and often complex enrollment and reimbursement requirements. Moreover, different states impose differing standards for their Medicaid programs. While our compliance program requires that we and our affiliated practices adhere to the laws and regulations applicable to the government programs in which we participate, our failure to comply with these laws and regulations could negatively affect our business, financial condition and results of operations. See “Government Regulation—Fraud and Abuse Provisions,” “Government Regulation—Compliance Program,” “Government Investigations” and “Other Legal Proceedings,” and Item 1A. Risk Factors—“Government programs or private insurers may limit, reduce or make retroactive adjustments to reimbursement amounts or rates,” “We may become subject to billing investigations by federal and state government authorities” and “The healthcare industry is highly regulated, and government authorities may determine that we have failed to comply with applicable laws or regulations.”

In addition, Medicaid, Medicare and other government healthcare programs (such as the TRICARE program) are subject to statutory and regulatory changes, administrative rulings, interpretations and determinations, requirements for utilization review and new governmental funding restrictions, all of which may materially increase or decrease program payments as well as affect the cost of providing services and the timing of payments to providers. Moreover, because these programs generally provide for reimbursement on a fee-schedule basis rather than on a charge-related basis, we generally cannot increase our revenue by increasing the amount we charge for our services. To the extent our costs increase, we may not be able to recover our increased costs from these programs, and cost containment measures and market changes in non-governmental insurance plans have generally restricted our ability to recover, or shift to non-governmental payors, these increased costs. In attempts to limit federal and state spending, there have been, and we expect that there will continue to be, a number of proposals to limit or reduce Medicaid and Medicare reimbursement for various services. Our business may be significantly and adversely affected by any such changes in reimbursement policies and other legislative initiatives aimed at reducing healthcare costs associated with Medicaid, Medicare and other government healthcare programs.

Our business also could be adversely affected by reductions in or limitations of reimbursement amounts or rates under these government programs, reductions in funding of these programs or elimination of coverage for certain individuals or treatments under these programs.

Antitrust

The healthcare industry is subject to close antitrust scrutiny. In recent years, the Federal Trade Commission (the “FTC”), the DOJ, and state Attorneys General have increasingly taken steps to review and, in some cases, take enforcement action against business conduct and acquisitions in the healthcare industry. Violations of antitrust laws may be punishable by substantial penalties, including significant monetary fines, civil penalties, criminal sanctions, consent decrees and injunctions prohibiting certain activities or requiring divestiture or discontinuance of business operations. Any of these penalties could have a material adverse effect on our business, financial condition and results of operations.

HIPAA and Other Privacy Laws

Numerous federal and state laws, rules and regulations govern the collection, dissemination, use and confidentiality of protected health information, including the federal Health Insurance Portability and Accountability Act of 1996, as amended (“HIPAA”), and its implementing regulations, violations of which are

punishable by monetary fines, civil penalties and, in some cases, criminal sanctions. As part of our medical record keeping, third-party billing, research and other services, we and our affiliated practices collect and maintain protected health information on the patients that we serve.

Pursuant to HIPAA, the U.S. Department of Health and Human Services (“HHS”) has adopted standards to protect the privacy and security of individually identifiable health information, known as the Privacy Standards and Security Standards. HHS’ Privacy Standards apply to medical records and other individually identifiable health information in any form, whether electronic, paper or oral, that is used or disclosed by healthcare providers, hospitals, health plans and healthcare clearinghouses, which are known as “Covered Entities.” We have implemented privacy policies and procedures, including training programs, designed to be compliant with the HIPAA Privacy Standards.

HHS’ Security Standards require healthcare providers to implement administrative, physical and technical safeguards to protect the integrity, confidentiality and availability of individually identifiable health information that is electronically received, maintained or transmitted (including between us and our affiliated practices). We have implemented security policies, procedures and systems designed to facilitate compliance with the HIPAA Security Standards.

In February 2009, Congress enacted the Health Information Technology for Economic and Clinical Health Act (“HITECH”) as part of the ARRA. Among other changes to the law governing protected health information, HITECH strengthens and expands HIPAA, increases penalties for violations, gives patients new rights to restrict uses and disclosures of their health information, and imposes a number of privacy and security requirements directly on our “Business Associates,” which are third-parties that perform functions or services for us or on our behalf. Specifically, HITECH requires that Covered Entities and Business Associates alike report any unauthorized use or disclosure of individually identifiable health information that meets the definition of a breach, to the affected individuals, HHS and, depending on the number of affected individuals, the media for the affected market. HITECH also authorizes state Attorneys General to bring civil actions in response to violations of HIPAA that threaten the privacy of state residents. As a result, we have made revisions to our privacy policies and procedures so that we are compliant with HITECH requirements.

In addition to the federal HIPAA and HITECH requirements, numerous other state and certain other federal laws protect the confidentiality of patient information, including state medical privacy laws, state social security number protection laws, human subjects research laws and federal and state consumer protection laws. In some cases, state laws are more stringent than HIPAA and therefore, are not preempted by HIPAA.

Environmental Regulations

Our healthcare operations generate medical waste that must be disposed of in compliance with federal, state and local environmental laws, rules and regulations. Our office-based operations are subject to compliance with various other environmental laws, rules and regulations. Such compliance does not, and we anticipate that such compliance will not, materially affect our capital expenditures, financial position or results of operations.

Compliance Program

We maintain a compliance program that reflects our commitment to complying with all laws, rules and regulations applicable to our business and that meets our ethical obligations in conducting our business (the “Compliance Program”). We believe our Compliance Program provides a solid framework to meet this commitment and our obligations as a provider of health care services, including:

•

a Chief Compliance Officer who reports to the Board of Directors on a regular basis;

•

a Compliance Committee consisting of our senior executives;

•

a formal internal audit function, including a Director of Internal Audit who reports to the Audit Committee on a regular basis;

•

our Code of Conduct, which is applicable to our employees, independent contractors, officers and directors;

•

our Code of Professional Conduct – Finance, which is applicable to our finance personnel, including our Chief Executive Officer, Chief Financial Officer and Treasurer (who is also our Chief Accounting Officer), Vice President of Accounting and Finance and Controller;

•

a disclosure program that includes a mechanism to enable individuals to disclose on a confidential or anonymous basis to the Chief Compliance Officer or any person who is not in the disclosing individual’s chain of command, issues or questions believed by the individual to be a potential violation of criminal, civil, or administrative laws;

•

an organizational structure designed to integrate our compliance objectives into our corporate offices, divisions, regions and practices; and

•

education, monitoring and corrective action programs designed to establish methods to promote the understanding of our Compliance Program and adherence to its requirements.

The foundation of our Compliance Program is our Code of Conduct, which is intended to be a comprehensive statement of the ethical and legal standards governing the daily activities of our employees, affiliated professionals, independent contractors, officers and directors. All our personnel are required to abide by, and are given thorough education regarding, our Code of Conduct. In addition, all employees and affiliated professionals are expected to report incidents that they believe in good faith may be in violation of our Code of Conduct. We maintain a toll-free helpline to permit individuals to report compliance concerns on an anonymous basis and obtain answers to questions about our Code of Conduct. Our Compliance Program, including our Code of Conduct, is administered by our Chief Compliance Officer with oversight by our Chief Executive Officer, Compliance Committee and Board of Directors. Copies of our Code of Conduct and our Code of Professional Conduct—Finance are available on our website, www.mednax.com. Our Internet website and the information contained therein or connected thereto are not incorporated into or deemed a part of this Form 10-K. Any amendments or waivers to our Code of Professional Conduct—Finance will be promptly disclosed on our website following the date of any such amendment or waiver.

GOVERNMENT INVESTIGATIONS

We expect that audits, inquiries and investigations from government authorities, agencies, contractors and payors will occur in the ordinary course of business. Such audits, inquiries and investigations and their ultimate resolutions, individually or in the aggregate, could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock.

OTHER LEGAL PROCEEDINGS

In the ordinary course of our business, we become involved in pending and threatened legal actions and proceedings, most of which involve claims of medical malpractice related to medical services provided by our affiliated physicians. Our contracts with hospitals generally require us to indemnify them and their affiliates for losses resulting from the negligence of our affiliated physicians. We may also become subject to other lawsuits that could involve large claims and significant defense costs. We believe, based upon a review of pending actions and proceedings, that the outcome of such legal actions and proceedings will not have a material adverse effect on our business, financial condition or results of operations. The outcome of such actions and proceedings, however, cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock.

Although we currently maintain liability insurance coverage intended to cover professional liability and certain other claims, we cannot assure that our insurance coverage will be adequate to cover liabilities arising out of claims asserted against us in the future where the outcomes of such claims are unfavorable to us. With respect to professional liability risk, we self-insure a significant portion of this risk through our wholly owned captive insurance subsidiary. Liabilities in excess of our insurance coverage, including coverage for professional liability and certain other claims, could have a material adverse effect on our business, financial condition and results of operations. See “Professional and General Liability Coverage.”

PROFESSIONAL AND GENERAL LIABILITY COVERAGE

We maintain professional and general liability insurance policies with third-party insurers on a claims-made basis, subject to deductibles, self-insured retention limits, policy aggregates, exclusions, and other restrictions, in accordance with standard industry practice. We believe that our insurance coverage is appropriate based upon our claims experience and the nature and risks of our business. However, we cannot assure that any pending or future claim will not be successful or if successful will not exceed the limits of available insurance coverage.

Our business entails an inherent risk of claims of medical malpractice against our affiliated physicians and us. We contract and pay premiums for professional liability insurance that indemnifies us and our affiliated healthcare professionals on a claims-made basis for losses incurred related to medical malpractice litigation. Professional liability coverage is required in order for our affiliated physicians to maintain hospital privileges. Our self-insured retention under our professional liability insurance program is maintained primarily through a wholly owned captive insurance subsidiary. We record estimates in our Consolidated Financial Statements for our liabilities for self-insured retention amounts and claims incurred but not reported based on an actuarial valuation using historical loss information, claim emergence patterns and various actuarial assumptions. Liabilities for claims incurred but not reported are not discounted. Because many factors can affect historical and future loss patterns, the determination of an appropriate reserve involves complex, subjective judgment, and actual results may vary significantly from estimates. If the self-insured retention amounts and other amounts that we are actually required to pay materially exceed the estimates that have been reserved, our financial condition, results of operations and cash flows could be materially adversely affected.

EMPLOYEES AND PROFESSIONALS UNDER CONTRACT

In addition to the over 2,100 practicing physicians affiliated with us as of December 31, 2012, we employed or contracted with over 2,200 other clinical professionals, including advanced practice nurses, and approximately 3,600 other full-time and part-time employees.

GEOGRAPHIC COVERAGE

We provide services in 34 states, including Alaska, Arizona, Arkansas, California, Colorado, Florida, Georgia, Idaho, Indiana, Illinois, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Missouri, Montana, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, Washington and West Virginia, and Puerto Rico. During 2012, approximately 59% of our net patient service revenue was generated by operations in our five largest states. Our operations in Texas accounted for approximately 24% of our net patient service revenue for the same period. Although we continue to seek to diversify the geographic scope of our operations, primarily through acquisitions of physician group practices, we may not be able to implement successfully or realize the expected benefits of any of these initiatives. Adverse changes or conditions affecting states in which our operations are concentrated, such as healthcare reforms, changes in laws and regulations, reduced Medicaid or Medicare reimbursements, an increase in the income level required to qualify for government healthcare programs or government investigations, may have a material adverse effect on our business, financial condition and results of operations.

ITEM 1A.

RISK FACTORS

Our business is subject to a number of factors that could materially affect future developments and performance. In addition to factors affecting our business that have been described elsewhere in this Form 10-K, any of the following risks could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock.

Continuing unfavorable economic conditions could have an adverse effect on our business.

The United States is continuing to be affected by unfavorable economic conditions and slow economic growth. The number of unemployed and under-employed workers remains significant. During the year ended December 31, 2012, the percentage of patient services being reimbursed under government-sponsored healthcare programs increased as compared to the year ended December 31, 2011. We could experience additional shifts if economic conditions do not improve or deteriorate further and possibly lower patient volumes. These conditions could also lead to additional increases in the number of unemployed and under-employed workers and a decline in the number of private employers that offer healthcare insurance coverage to their employees. Employers that do offer healthcare coverage may increase the required contributions from employees to pay for their coverage and increase patient responsibility amounts. As a consequence, the number of patients who participate in government-sponsored programs or are uninsured could increase. In addition, we cannot predict whether the Affordable Care Act will increase or decrease the number of patients with private healthcare insurance, obtained either through employers or the to be established insurance exchanges. Payments received from government-sponsored programs are substantially less than payments received from managed care and other third-party payors. A payor mix shift from managed care and other third-party payors to government payors may result in an increase in our estimated provision for contractual adjustments and uncollectibles and a corresponding decrease in our net patient service revenue. Further increases in the government component of our payor mix at the expense of other third-party payors could result in a significant reduction in our average reimbursement rates.

State budgetary constraints could have an adverse effect on our reimbursement from Medicaid programs.

As a result of slow economic growth, many states are continuing to collect less revenue than they did in prior years and as a consequence are facing significant budget shortfalls and underfunded pension and other obligations. Although the shortfalls for the budget year beginning in July 2012 were lower than in recent years, they are still significant by historical standards. Financial conditions in the states where the Company does business could lead to reduced or delayed funding for Medicaid programs and, in turn, reduced or delayed reimbursement for physician services, which could adversely affect our results of operations, cash flows and financial condition.

The birth rate in the United States has declined and may continue to fall.

Provisional data for 2011 indicates that the births in the United States declined by 1.0% from 2010, which fell by 3.0% from 2009. Although the provisional data is not yet available for 2012, we expect that birth trends may have improved in 2012 as compared to the prior few years. However, any declines in births could have an adverse effect on our patient volumes and revenue.

The Affordable Care Act may have a significant effect on our business.

In March 2010, the Affordable Care Act was enacted. The Affordable Care Act contains a number of provisions that could affect us over the next several years. These provisions include establishing health insurance exchanges to facilitate the purchase of qualified health plans, expanding Medicaid eligibility, subsidizing insurance premiums and creating requirements and incentives for businesses to provide healthcare benefits. Other provisions contain changes to healthcare fraud and abuse laws and expand the scope of the Federal False Claims Act.

The Affordable Care Act contains numerous other measures that could also affect us. For example, payment modifiers are to be developed that will differentiate payments to physicians under federal healthcare programs based on quality of care. In addition, other provisions authorize voluntary demonstration projects relating to the bundling of payments for episodes of hospital care and the sharing of cost savings achieved under the Medicare program.

In October 2011, the Centers for Medicare and Medicaid Services (“CMS”) issued a final rule under the Affordable Care Act that is intended to allow physicians, hospitals and other health care providers to coordinate care for Medicare beneficiaries through Accountable Care Organizations (“ACOs”). ACOs are entities consisting of healthcare providers and suppliers organized to deliver services to Medicare beneficiaries and eligible to receive a share of any cost savings the entity can achieve by delivering services to those beneficiaries at a cost below a set baseline and with sufficient quality of care. We will continue to evaluate the impact of the ACO regulations on our business and operations.

Many of the Affordable Care Act’s most significant reforms, such as the establishment of state-based and federally facilitated insurance exchanges, do not take effect until 2014 and thereafter, and their details will be shaped significantly by implementing regulations that have yet to be finalized. In 2012, the U.S. Supreme Court heard challenges to the constitutionality of the Affordable Care Act’s individual mandate to purchase health insurance and to the viability of certain other provisions of the law. The Supreme Court issued a decision upholding most of the Affordable Care Act and determined that requiring individuals to maintain “minimum essential” health insurance coverage or pay a penalty to the Internal Revenue Service was within Congress’ constitutional taxing authority. However, the Supreme Court struck down a provision in the Affordable Care Act that penalized states that choose not to expand their Medicaid programs through an increase in the Medicaid eligibility income limit from a state’s current eligibility levels to 133% of the federal poverty limit. As a result of the Supreme Court’s ruling, it is unclear to what extent states will expand their Medicaid programs by raising the income limit to 133% of the federal poverty level and whether there will be more uninsured patients in 2014 than anticipated when the Affordable Care Act was enacted.

Federal and state agencies are expected to continue to implement provisions of the Affordable Care Act and to develop regulations following the Supreme Court’s decision. However, given the complexity and the number of changes expected as a result of the Affordable Care Act, as well as the implementation timetable for many of them, we cannot predict the ultimate impacts of the Affordable Care Act, as they may not be known for several years. The Affordable Care Act also remains subject to continuing legislative scrutiny, including efforts by Congress to amend or repeal a number of its provisions. As a result, we cannot predict with any assurance the ultimate effect of the Affordable Care Act on our Company, nor can we provide any assurance that its provisions will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

Expanding eligibility of government-sponsored programs could adversely affect our reimbursement.

In February 2009, Congress reauthorized the State Children’s Health Insurance Program (“SCHIP”) through September 2013 and expanded its eligibility coverage. Further expansion of SCHIP eligibility and the Affordable Care Act’s expansion of Medicaid coverage could cause patients who otherwise would have participated in private healthcare insurance programs to participate in government-sponsored programs. Additional reform efforts could change the eligibility requirements for Medicaid and for other government-sponsored programs and could increase the number of patients who participate in such programs or the number of uninsured patients. Payments received from government-sponsored programs are substantially less than payments received from managed care and other third-party payors. A payor mix shift from managed care and other third-party payors to government payors may result in an increase in our estimated provision for contractual adjustments and uncollectibles and a corresponding decrease in our net patient service revenue. Further increases in the government component of our payor mix at the expense of other third-party payors could also result in a significant reduction in our average reimbursement rates.

Government programs or private insurers may limit, reduce or make retroactive adjustments to reimbursement amounts or rates.

A significant portion of our net patient revenue is derived from payments made by government-sponsored healthcare programs, principally Medicaid. These government programs, as well as private insurers, have taken and may continue to take steps, including a movement toward increased use of managed care organizations, value-based purchasing, and new patient care models, to control the cost, eligibility for, use and delivery of healthcare services as a result of budgetary constraints and cost containment pressures due to unfavorable economic conditions, rising healthcare costs and for other reasons, including those described above under Item 1. Business—“Government Regulation—Government Reimbursement Requirements.” These government programs and private insurers may attempt other measures to control costs, including bundling of services and denial of or reduction in reimbursement for certain services and treatments. As a result, payments from government programs or private payors may decrease significantly. Also, any adjustment in Medicare reimbursement rates may have a detrimental impact on our reimbursement rates not only for Medicare patients, but also because Medicaid and other third-party payors often base their reimbursement rates on a percentage of Medicare reimbursement rates. Our business also may be materially affected by limitations on or reductions in reimbursement amounts or rates or elimination of coverage for certain individuals or treatments. Moreover, because government programs generally provide for reimbursements on a fee-schedule basis rather than on a charge-related basis, we generally cannot increase our revenues from these programs by increasing the amount we charge for our services. To the extent our costs increase, we may not be able to recover our increased costs from these programs, and cost containment measures and market changes in non-governmental insurance plans have generally restricted our ability to recover, or shift to non-governmental payors, these increased costs. In addition, funds we receive from third-party payors are subject to audit with respect to the proper billing for physician and ancillary services and, accordingly, our revenue from these programs may be adjusted retroactively. Any retroactive adjustments to our reimbursement amounts could have a material effect on our financial condition, results of operations, cash flows and the trading price of our common stock.

In addition, Medicare reimbursement rates could be reduced due to formulaic rules. Presently, Medicare pays for all physician services based upon a national fee schedule which contains a list of uniform rates. The payment rates under the fee schedule are determined based on national uniform relative value units for the services provided, a geographic adjustment factor and a conversion factor. The fee schedule is adjusted annually based on a complex formula that is linked in part to the use of services by Medicare beneficiaries and the growth in gross domestic product. Since 2002, this formula has resulted in negative payment updates under the fee schedule that have grown increasingly larger, and Congress has had to take repeated legislative action to reverse scheduled payment reductions, most recently in January 2013, when legislation was enacted to avert a rate reduction and temporarily extend existing Medicare physician payment rates through the end of December 2013. If Congress does not take further action, the Medicare fee schedule will be reduced by approximately 27% effective January 1, 2014. Fee reductions will continue to be scheduled annually and will grow to approximately 40% in cumulative reductions by 2016 unless Congress takes action in the future to modify or reform the mechanism by which payment rates are updated. In addition to the reductions under the Medicare fee schedule, the Budget Control Act of 2011 sets forth across-the-board cuts (“sequestrations”) to Medicare reimbursement rates which are scheduled to begin in April 2013. These annual reductions of 2% apply to mandatory and discretionary spending in the years 2013 to 2021. Unless Congress takes action in the future to modify these sequestrations, Medicare reimbursements will be reduced by 2% annually and will grow to approximately 10% in cumulative reductions by 2021. If no action is taken, reductions in the fee schedule and reductions as a result of the sequestrations could have a material adverse effect on our financial condition, results of operations, cash flows and the trading price of our common stock.

We may become subject to billing investigations by federal and state government authorities.

State and federal statutes impose substantial penalties, including civil and criminal fines, exclusion from participation in government healthcare programs and imprisonment, on entities or individuals (including any individual corporate officers or physicians deemed responsible) that fraudulently or wrongfully bill governmental

or other third-party payors for healthcare services. In September 2011, CMS issued a final rule requiring states to implement a Medicaid Recovery Audit Contractor (“RAC”) program effective January 1, 2012. States are required to contract with one or more eligible Medicaid RACs to review Medicaid claims for any overpayments or underpayments, and to recoup overpayments from providers on behalf of the state. In addition, federal laws, along with a growing number of state laws, allow a private person to bring a civil action in the name of the government for false billing violations. See Item 1. Business—“Government Regulation—Fraud and Abuse Provisions.” We believe that audits, inquiries and investigations from government agencies will occur from time to time in the ordinary course of our business, which could result in substantial defense costs to us and a diversion of management’s time and attention. We cannot predict whether any future audits, inquiries or investigations, or the public disclosure of such matters, would have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock. See Item 1. Business—“Government Investigations.”

The healthcare industry is highly regulated, and government authorities may determine that we have failed to comply with applicable laws or regulations.

The healthcare industry and physicians’ medical practices, including the healthcare and other services that we and our affiliated physicians provide, are subject to extensive and complex federal, state and local laws and regulations, compliance with which imposes substantial costs on us. Of particular importance are the provisions summarized as follows:

•

federal laws (including the federal False Claims Act) that prohibit entities and individuals from knowingly or recklessly making claims to Medicaid, Medicare and other government programs that contain false or fraudulent information or from improperly retaining known overpayments;

•

a provision of the Social Security Act, commonly referred to as the “anti-kickback” law, that prohibits the knowing and willful offer, payment, solicitation or receipt of any bribe, kickback, rebate or other remuneration, in cash or in kind, in return for the referral or recommendation of patients for items and services covered, in whole or in part, by federal healthcare programs, such as Medicaid and Medicare;

•

a provision of the Social Security Act, commonly referred to as the Stark Law, that, subject to limited exceptions, prohibits physicians from referring Medicare patients to an entity for the provision of certain “designated health services” if the physician or a member of such physician’s immediate family has a direct or indirect financial relationship (including a compensation arrangement) with the entity;

•

similar state law provisions pertaining to anti-kickback, fee splitting, self-referral and false claims issues, which typically are not limited to relationships involving federal payors;

•

provisions of HIPAA that prohibit knowingly and willfully executing a scheme or artifice to defraud a healthcare benefit program or falsifying, concealing or covering up a material fact or making any material false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services;

•

state laws that prohibit general business corporations from practicing medicine, controlling physicians’ medical decisions or engaging in certain practices, such as splitting fees with physicians;

•

federal and state laws that prohibit providers from billing and receiving payment from Medicaid or Medicare for services unless the services are medically necessary, adequately and accurately documented and billed using codes that accurately reflect the type and level of services rendered;

•

federal and state laws pertaining to the provision of services by non-physician practitioners, such as advanced nurse practitioners, physician assistants and other clinical professionals, physician supervision of such services and reimbursement requirements that may be dependent on the manner in which the services are provided and documented; and

•

federal laws that impose civil administrative sanctions for, among other violations, inappropriate billing of services to federally funded healthcare programs, inappropriately reducing hospital care lengths of stay for such patients, or employing individuals who are excluded from participation in federally funded healthcare programs.

In addition, we believe that our business will continue to be subject to increasing regulation, the scope and effect of which we cannot predict. See Item 1. Business—“Government Regulation.”

We may in the future become the subject of regulatory or other investigations or proceedings, and our interpretations of applicable laws, rules and regulations may be challenged. For example, regulatory authorities or other parties may assert that our arrangements with our affiliated professional contractors constitute fee splitting or the corporate practice of medicine and seek to invalidate these arrangements, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock. See Item 1. Business—“Government Regulation—Fee Splitting; Corporate Practice of Medicine.” Regulatory authorities or other parties also could assert that our relationships, including fee arrangements, among our affiliated professional contractors, hospital clients or referring physicians violate the anti-kickback, fee splitting or self-referral laws and regulations or that we have submitted false claims or otherwise failed to comply with government program reimbursement requirements. See Item 1. Business—“Government Regulation—Fraud and Abuse Provisions” and “—Government Reimbursement Requirements.” Such investigations, proceedings and challenges could result in substantial defense costs to us and a diversion of management’s time and attention. In addition, violations of these laws are punishable by monetary fines, civil and criminal penalties, exclusion from participation in government-sponsored healthcare programs, and forfeiture of amounts collected in violation of such laws and regulations, any of which could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock.

Federal and state laws that protect the privacy and security of protected health information may increase our costs and limit our ability to collect and use that information and subject us to penalties if we are unable to fully comply with such laws.

Numerous federal and state laws and regulations govern the collection, dissemination, use, security and confidentiality of individually identifiable health information. These laws include:

•

Provisions of HIPAA that limit how healthcare providers may use and disclose individually identifiable health information, provide certain rights to individuals with respect to that information and impose certain security requirements;

•

HITECH, which strengthens and expands the HIPAA Privacy Standards and Security Standards;

•

Other federal and state laws restricting the use and protecting the privacy and security of protected information, many of which are not preempted by HIPAA;

•

Federal and state consumer protection laws; and

•

Federal and state laws regulating the conduct of research with human subjects.

As part of our medical record keeping, third-party billing, research and other services, we collect and maintain protected health information in paper and electronic format. New protected health information standards, whether implemented pursuant to HIPAA, HITECH, congressional action or otherwise, could have a significant effect on the manner in which we handle healthcare-related data and communicate with payors, and compliance with these standards could impose significant costs on us or limit our ability to offer services, thereby negatively impacting the business opportunities available to us.

If we do not comply with existing or new laws and regulations related to protected health information we could be subject to remedies that include monetary fines, civil or administrative penalties or criminal sanctions.

Government authorities or other parties may assert that our business practices violate antitrust laws.

The healthcare industry is subject to close antitrust scrutiny. In recent years, the FTC, the DOJ and state Attorneys General have taken increasing steps to review and, in some cases, take enforcement action against business conduct and acquisitions in the healthcare industry. Violations of antitrust laws may be punishable by substantial penalties, including significant monetary fines, civil penalties, criminal sanctions, and consent decrees and injunctions prohibiting certain activities or requiring divestiture or discontinuance of business operations. Any of these penalties could have a material adverse effect on our business, financial condition and results of operations.

Our affiliated physicians may not appropriately record or document services they provide.

Our affiliated physicians are responsible for maintaining sufficient supporting documentation for the services they provide. We use this information to seek reimbursement for their services from third-party payors. If our physicians do not appropriately document, or where applicable, code for their services, we could be subjected to administrative, regulatory, civil, or criminal investigations or sanctions and our business, financial condition, results of operations and cash flows could be adversely affected.

We may not find suitable acquisition candidates or successfully integrate our acquisitions. Our acquisitions may expose us to greater business risks and could affect our payor mix.

We have expanded and intend to continue to seek to expand our presence in new and existing metropolitan areas for us by acquiring established neonatal, maternal-fetal, pediatric cardiology and other complementary pediatric subspecialty physician groups and anesthesia care practices.

Our acquisition strategy involves numerous risks and uncertainties, including:

•

We may not be able to identify suitable acquisition candidates or strategic opportunities or implement successfully or realize the expected benefits of any suitable opportunities. In addition, we compete for acquisitions with other potential acquirers, some of which may have greater financial or operational resources than we do. This competition may intensify due to the ongoing consolidation in the healthcare industry, which may increase our acquisition costs.

•

We may not be able to complete acquisitions of physician practices or we may complete acquisitions on less favorable terms as a result of higher tax rates on high-income individuals resulting from the American Taxpayer Relief Act of 2012. Specifically, our acquisition candidates may require a higher purchase price to compensate them for this increased tax burden.

•

We may not be able to successfully integrate completed acquisitions, including our recent acquisitions. Integrating completed acquisitions into our existing operations involves numerous short-term and long-term risks, including diversion of our management’s attention, failure to retain key personnel, long-term value of acquired intangible assets and acquisition expenses. In addition, we may be required to comply with laws and regulations that may differ from those of the states in which our operations are currently conducted.

•

We cannot be certain that any acquired business will continue to maintain its pre-acquisition revenues and growth rates or be financially successful. In addition, we cannot be certain of the extent of any unknown or contingent liabilities of any acquired business, including liabilities for failure to comply with applicable laws, including laws relating to medical malpractice. Generally we obtain indemnification agreements from the sellers of businesses acquired with respect to pre-closing acts, omissions and other similar risks. It is possible that we may seek to enforce indemnification provisions in the future against sellers who may no longer have the financial wherewithal to satisfy their obligations to us. Accordingly, we may incur material liabilities for past activities of acquired businesses.

•

We could incur or assume indebtedness and issue equity in connection with acquisitions. The issuance of shares of our common stock for an acquisition may result in dilution to our existing shareholders and, depending on the number of shares that we issue, the resale of such shares could affect the trading price of our common stock.

•

We may acquire businesses that derive a greater portion of their revenue from government-sponsored programs than what we recognize on a consolidated basis. These acquisitions could affect our overall payor mix in future periods.

•

Acquisitions of practices could entail financial and operating risks not fully anticipated. Such acquisitions could divert management’s attention and our resources.

•

An acquisition could be subject to a challenge under the antitrust laws either before or after it is consummated. Such a challenge could involve substantial legal costs and divert management’s attention and resources and could result in us having to abandon the transaction or make a divestiture.

We may not be able to successfully execute our same-unit and organic growth strategies.

In addition to our acquisition growth strategy, we seek opportunities for increasing revenue from our existing hospital- and office-based operations through same-unit and organic growth strategies. We may not be able to successfully execute our same-unit and organic growth strategies for the following reasons:

•

We may not be able to expand the services that our affiliated physicians provide to our hospital partners.

•

We may not be able to attract referrals or neonatology transports to our hospital-based units and our office-based practices.

•

We may not be able to execute new contractual arrangements with hospitals where we do not currently provide physician services.

•

We may not be able to work with our hospital partners to develop integrated services programs for which we become a multi-specialty provider of solutions within the maternal-fetal, newborn, pediatric continuum of care.

We may not be able to maintain effective and efficient information systems or properly safeguard our information systems.

Our operations are dependent on uninterrupted performance of our information systems. Failure to maintain reliable information systems, disruptions in our existing information systems or the implementation of new systems could cause disruptions in our business operations, including errors and delays in billings and collections, difficulty satisfying requirements under hospital contracts, disputes with patients and payors, violations of patient privacy and confidentiality requirements and other regulatory requirements, increased administrative expenses and other adverse consequences.

In addition, information security risks have generally increased in recent years because of new technologies and the increased activities of perpetrators of cyber attacks. A failure in or breach of our information systems as a result of cyber attacks could also disrupt our business, result in the release or misuse of confidential or proprietary information, damage our reputation, and increase our administrative expenses. Although we believe that we have robust information security procedures and other safeguards in place, as cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures or to investigate and remediate any information security vulnerabilities. Any of these disruptions or breaches of security could have a material adverse effect on our business, financial condition and results of operations.

Our employees and business partners may not appropriately secure and protect confidential information in their possession.

Each of our employees and business partners is responsible for the security of the information in our systems and to ensure that private and financial information is kept confidential. Should an employee or business partner not follow appropriate security measures, including those related to cyber threats or attacks, it may result in the release of private or confidential financial information. The release of such information could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may not be able to successfully recruit and retain qualified physicians to serve as affiliated physicians or independent contractors.

We are dependent upon our ability to recruit and retain a sufficient number of qualified physicians to service existing units at hospitals and our affiliated practices and expand our business. We compete with many types of healthcare providers, including teaching, research and government institutions and other practice groups, for the services of qualified physicians. We may not be able to continue to recruit new physicians or renew contracts with existing physicians on acceptable terms. If we do not do so, our ability to service existing or new hospital units and staff existing or new office-based practices could be adversely affected.

A significant number of our affiliated physicians could leave our affiliated practices or our affiliated professional contractors may be unable to enforce the non-competition covenants of departed physicians.

Our affiliated professional contractors usually enter into employment agreements with our affiliated physicians. Certain of our employment agreements can be terminated without cause by any party upon prior written notice. In addition, substantially all of our affiliated physicians have agreed not to compete within a specified geographic area for a certain period after termination of employment. The law governing non-compete agreements and other forms of restrictive covenants varies from state to state. Although we believe that the non-competition and other restrictive covenants applicable to our affiliated physicians are reasonable in scope and duration and therefore enforceable under applicable state law, courts and arbitrators in some states are reluctant to strictly enforce non-compete agreements and restrictive covenants against physicians. If a substantial number of our affiliated physicians leave our affiliated practices or our affiliated professional contractors are unable to enforce the non-competition covenants in the employment agreements, our business, financial condition, results of operations and cash flows could be materially adversely affected. We cannot predict whether a court or arbitration panel would enforce these covenants.

We may be subject to medical malpractice and other lawsuits not covered by insurance.

Our business entails an inherent risk of claims of medical malpractice against our affiliated physicians and us. We may also be subject to other lawsuits which may involve large claims and significant defense costs. Although we currently maintain liability insurance coverage intended to cover professional liability and other claims, there can be no assurance that our insurance coverage will be adequate to cover liabilities arising out of claims asserted against us where the outcomes of such claims are unfavorable to us. Generally, we self-insure our liabilities to pay retention amounts for professional liability matters through a wholly owned captive insurance subsidiary. Liabilities in excess of our insurance coverage, including coverage for professional liability and other claims, could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock. See Item 1. Business—“Other Legal Proceedings” and “Professional and General Liability Coverage.”

The reserves that we have established in respect of our professional liability losses are subject to inherent uncertainties and if a deficiency is determined this may lead to a reduction in our net earnings.

We have established reserves for losses and related expenses that represent estimates involving actuarial projections, at a given point in time, of our expectations of the ultimate resolution and administration of costs of losses incurred with respect to professional liability risks for the amount of risk retained by us. Insurance reserves are inherently subject to uncertainty. Our reserve estimates are based on actuarial valuations using historical claims, demographic factors, industry trends, severity and exposure factors and other actuarial assumptions. The

estimates of projected ultimate losses are developed at least annually. Our reserves could be significantly affected should current and future occurrences differ from historical claim trends and expectations. While claims are monitored closely when estimating reserves, the complexity of the claims and wide range of potential outcomes often hamper timely adjustments to the assumptions used in these estimates. Actual losses and related expenses may deviate, perhaps substantially, from the reserve estimates reflected in our financial statements. If our estimated reserves are determined to be inadequate, we will be required to increase reserves at the time the deficiency is determined. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—“Application of Critical Accounting Policies and Estimates—Professional Liability Coverage.”

We may write-off intangible assets, such as goodwill.

Our intangible assets, which consist primarily of goodwill related to our acquisitions, are subject to annual impairment testing. Under current accounting standards, goodwill is tested for impairment on an annual basis and we may be subject to impairment losses as circumstances change after an acquisition. If we record an impairment loss related to our goodwill, it could have a material adverse effect on our results of operations for the year in which the impairment is recorded.

We may not effectively manage our growth.

We have experienced significant growth in our business and the number of our employees and affiliated physicians in recent years which places significant demands on our financial, operational and management resources. Continued growth may impair our ability to provide our services efficiently and to manage our employees adequately. While we are taking steps to manage our growth, our future results of operations could be materially adversely affected if we are unable to do so effectively.

Our quarterly results will likely fluctuate from period to period.

We have historically experienced and expect to continue to experience quarterly fluctuations in net patient service revenue and net income. For example, we typically experience negative cash flow from operations in the first quarter of each year, principally as a result of bonus payments to affiliated physicians as well as discretionary matching contributions for participants in our qualified contributory savings plans (401(k) Plans). In addition, a significant number of our employees and associated professional contractors (primarily affiliated physicians) exceed the level of taxable wages for social security contributions during the first and second quarters. As a result, we incur a significantly higher payroll tax burden and our net income is lower during those quarters. Moreover, a lower number of calendar days are present in the first and second quarters of the year as compared to the remainder of the year. Because we provide services in the NICU on a 24-hours-a-day basis, 365 days a year, any reduction in service days will have a corresponding reduction in net patient service revenue. In addition, any reduction in office days in our office-based practices will also have a corresponding reduction in net patient service revenue. We also have significant fixed operating costs, including costs for our affiliated physicians, and as a result, are highly dependent on patient volume and capacity utilization of our affiliated physicians to sustain profitability. Quarterly results may also be impacted by the timing of acquisitions and any fluctuation in patient volume. As a result, our results of operations for any quarter are not indicative of results of operations for any future period or full fiscal year.

The value of our common stock may fluctuate.

There has been significant volatility in the market price of securities of healthcare companies generally that we believe in many cases has been unrelated to operating performance. In addition, we believe that certain factors, such as legislative and regulatory developments, including announced regulatory investigations, quarterly fluctuations in our actual or anticipated results of operations, lower revenues or earnings than those anticipated by securities analysts, and general economic and financial market conditions, could cause the price of our common stock to fluctuate substantially.

We may not be able to collect reimbursements for our services from third-party payors in a timely manner.

A significant portion of our net patient service revenue is derived from reimbursements from various third-party payors, including government-sponsored healthcare plans, private insurance plans and managed care plans, for services provided by our affiliated professional contractors. We are responsible for submitting reimbursement requests to these payors and collecting the reimbursements, and we assume the financial risks relating to uncollectible and delayed reimbursements. In the current healthcare environment, payors continue their efforts to control expenditures for healthcare, including revisions to coverage and reimbursement policies. Due to the nature of our business and our participation in government and private reimbursement programs, we are involved from time to time in inquiries, reviews, audits and investigations by governmental agencies and private payors of our business practices, including assessments of our compliance with coding, billing and documentation requirements. We may be required to repay these agencies or private payors if a finding is made that we were incorrectly reimbursed, or we may be subjected to pre-payment reviews, which can be time-consuming and result in non-payment or delayed payment for the services we provide. We may also experience difficulties in collecting reimbursements because third-party payors may seek to reduce or delay reimbursements to which we are entitled for services that our affiliated physicians have provided. If we are not reimbursed fully and in a timely manner for such services or there is a finding that we were incorrectly reimbursed, our revenue, cash flows and financial condition could be materially adversely affected.

In addition, adverse economic conditions could affect the timeliness and amounts received from our third-party and government payors which would impact our short-term liquidity needs.

Hospitals may terminate their agreements with us, our physicians may lose the ability to provide services in hospitals or administrative fees paid to us by hospitals may be reduced.

Our net patient service revenue is derived primarily from fee-for-service billings for patient care provided within hospital units by our affiliated physicians and from administrative fees paid to us by hospitals. See Item 1. Business—“Relationships with Our Partners—Hospitals.” Our hospital partners may cancel or not renew their contracts with us, reduce or eliminate our administrative fees in the future, or refuse to pay us our administrative fees if we fail to honor the terms of our agreement. Adverse economic conditions could influence future actions of our hospital partners. To the extent that our arrangements with our hospital partners are canceled, or are not renewed or replaced with other arrangements having at least as favorable terms, our business, financial condition and results of operations could be adversely affected. In addition, to the extent our affiliated physicians lose their privileges in hospitals or hospitals enter into arrangements with or employ other physicians, our business, financial condition, results of operations and cash flows could be materially adversely affected.

Hospitals could limit our ability to use our management information systems in our units by requiring us to use their own management information systems.

Our management information systems, including BabySteps^® and Quantum Clinical Navigation Systems are used to support our day-to-day operations and ongoing clinical research and business analysis. If a hospital prohibits us from using our own management information systems, it may interrupt the efficient operation of our information systems which, in turn, may limit our ability to operate important aspects of our business, including billing and reimbursement as well as research and education initiatives. This inability to use our management information systems at hospital locations may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our industry is already competitive and could become more competitive.

The healthcare industry is highly competitive and subject to continual changes in the methods by which services are provided and the manner in which healthcare providers are selected and compensated. Because our operations consist primarily of physician services provided within hospital-based units, we compete with other healthcare services companies and physician groups for contracts with hospitals to provide our services to patients. We also face competition from hospitals themselves to provide our services. Companies in other healthcare industry segments, some of which have greater financial and other resources than ours, may become

competitors in providing neonatal, maternal-fetal, pediatric subspecialty care or anesthesia care. Additionally, we face competition from healthcare-focused and other private equity firms. We may not be able to continue to compete effectively in this industry, additional competitors may enter metropolitan areas where we operate, and this increased competition may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Unfavorable changes or conditions could occur in the states where our operations are concentrated.

A majority of our net patient service revenue in 2012 was generated by our operations in five states. In particular, Texas accounted for approximately 24% of our net patient service revenue in 2012. See Item 1. Business—“Geographic Coverage.” Adverse changes or conditions affecting these particular states, such as healthcare reforms, changes in laws and regulations, reduced Medicaid reimbursements and government investigations, economic conditions and natural disasters may have a material adverse effect on our business, financial condition, results of operations and cash flows.

We are dependent upon our key management personnel for our future success.

Our success depends to a significant extent on the continued contributions of our key management personnel, including our Chief Executive Officer, Roger J. Medel, M.D., for the management of our business and implementation of our business strategy. The loss of Dr. Medel or other key management personnel could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price of our common stock.

Provisions of our articles and bylaws could deter takeover attempts.

Our Amended and Restated Articles of Incorporation authorize our board of directors to issue up to 1,000,000 shares of undesignated preferred stock and to determine the powers, preferences and rights of these shares without shareholder approval. This preferred stock could be issued with voting, liquidation, dividend and other rights superior to those of the holders of common stock. The issuance of preferred stock under some circumstances could have the effect of delaying, deferring or preventing a change in control. In addition, provisions in our amended and restated articles of incorporation and bylaws, including those relating to calling shareholder meetings, taking action by written consent and other matters, could render it more difficult or discourage an attempt to obtain control of MEDNAX through a proxy contest or consent solicitation. These provisions could limit the price that some investors might be willing to pay in the future for our shares of common stock.

Price Range of Common Stock

Our common stock is traded on the New York Stock Exchange (the “NYSE”) under the symbol “MD.” The high and low sales prices for a share of our common stock for each quarter during our last two fiscal years are set forth below:


	High		Low
2012
First Quarter	$	75.86	$	66.95
Second Quarter		74.67		59.24
Third Quarter		76.67		60.90
Fourth Quarter		81.73		67.86

2011
First Quarter	$	70.17	$	58.96
Second Quarter		75.47		65.49
Third Quarter		74.70		58.48
Fourth Quarter		72.58		59.85

As of February 7, 2013, we had 271 holders of record of our common stock, and the closing sales price on that date for our common stock was $85.57 per share. We believe that the number of beneficial owners of our common stock is greater than the number of record holders because a significant number of shares of our common stock is held through brokerage firms in “street name.”

Dividend Policy

We did not declare or pay any cash dividends on our common stock in 2012 or 2011, nor do we currently intend to declare or pay any cash dividends in the future. The payment of any future dividends will be at the discretion of our Board of Directors and will depend upon, among other things, future earnings, results of operations, capital requirements, our general financial condition, general business conditions and contractual restrictions on payment of dividends, if any, as well as such other factors as our Board of Directors may deem relevant. Our revolving line of credit restricts our ability to declare and pay cash dividends. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—“Liquidity and Capital Resources.”

Performance Graph

The following graph compares the cumulative total shareholder return on $100 invested on December 31, 2007 in our common stock against the cumulative total return of the S&P 500 Index, S&P 600 Health Care Index, and the NYSE Composite Index. The returns are calculated assuming reinvestment of dividends. The graph covers the period from December 31, 2007 through December 31, 2012.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion highlights the principal factors that have affected our financial condition and results of operations as well as our liquidity and capital resources for the periods described. This discussion should be read in conjunction with our Consolidated Financial Statements and the related notes included in Item 8 of this Form 10-K. This discussion contains forward-looking statements. Please see the explanatory note concerning “Forward-Looking Statements” preceding Part I of this Form 10-K and Item 1A. Risk Factors for a discussion of the uncertainties, risks and assumptions associated with these forward-looking statements. The operating results for the periods presented were not significantly affected by inflation.

OVERVIEW

MEDNAX is a leading provider of physician services including newborn, maternal-fetal, other pediatric subspecialties, and anesthesia care. At December 31, 2012, our national network was composed of more than 2,100 affiliated physicians, including more than 1,000 physicians who provide neonatal clinical care in 34 states and Puerto Rico, primarily within hospital-based neonatal intensive care units, to babies born prematurely or with medical complications. We have approximately 200 affiliated physicians who provide maternal-fetal and obstetrical medical care to expectant mothers experiencing complicated pregnancies primarily in areas where our affiliated neonatal physicians practice. Our network includes other pediatric subspecialists, including approximately 120 physicians providing pediatric cardiology care, 100 physicians providing pediatric intensive care, 60 physicians providing hospital-based pediatric care and 15 physicians providing pediatric surgical care. In addition, we have over 625 physicians who provide anesthesia care to patients in connection with surgical and other procedures as well as pain management.

During the year ended December 31, 2012, we completed the acquisition of 16 physician group practices. These acquisitions consisted of eight anesthesiology practices, two maternal-fetal medicine practices, two pediatric cardiology practices, one neonatal practice, and three other pediatric subspecialty practices. Based on our experience, we expect that we can improve the results of these practices through improved managed care contracting, improved collections, identification of growth initiatives, as well as, operating and cost savings based upon the significant infrastructure that we have developed.

With the acquisition of eight established practices, we continued the expansion of our anesthesia platform, bringing the number of anesthesia groups acquired since 2007 to 17. We also continued to focus on the integration of previously acquired practices and the ongoing development of the infrastructure to support those practices. Our national network of physicians and clinical professionals now includes over 625 anesthesiologists and approximately 850 advanced practice anesthetists who provide services in 17 metropolitan areas. We continue to believe that there are additional opportunities to apply our administrative expertise in this practice area, and we intend to pursue the acquisition of additional anesthesia practices in 2013.

In November 2012, we amended and restated our unsecured revolving credit facility (“Line of Credit”) to increase our borrowing capacity to $800 million from $500 million and to extend the maturity date to November 2017. The Line of Credit provides a funding source for future acquisitions, as well as other corporate purposes. The Line of Credit is guaranteed by substantially all of our subsidiaries and affiliated professional contractors and includes a $75 million sub-facility for the issuance of letters of credit and a $37.5 million sub-facility for swingline loans. In addition, the Line of Credit may be increased to $1.0 billion subject to the satisfaction of specified conditions.

government-sponsored programs and patient volumes could decline if economic conditions do not improve or deteriorate further. Payments received from government-sponsored programs are substantially less for equivalent services than payments received from commercial insurance payors. In addition, many states are continuing to experience lower than anticipated revenue and are facing significant budget shortfalls. Although the shortfalls for the budget year beginning in July 2012 were lower than in recent years, they are still significant by historical standards. These shortfalls could lead to reduced or delayed funding for state Medicaid programs and, in turn, reduced or delayed reimbursement for physician services. See Item 1A. Risk Factors, in this Form 10-K for additional discussion on the general economic conditions in the United States and recent developments in the healthcare industry that could affect our business.

In March 2010, the “Patient Protection and Affordable Care Act,” (the “Affordable Care Act” formerly referred to as the “Healthcare Reform Act”), was enacted. The Affordable Care Act contains a number of provisions that could affect us over the next several years. These provisions include establishing health insurance exchanges to facilitate the purchase of qualified health plans, expanding Medicaid eligibility, subsidizing insurance premiums and creating requirements and incentives for businesses to provide healthcare benefits. Other provisions contain changes to healthcare fraud and abuse laws and expand the scope of the Federal False Claims Act. Additionally, in November 2012, the Centers for Medicare & Medicaid Services (“CMS”) adopted a rule under the Affordable Care Act that would allow physicians who provide eligible primary care services to generally be paid at the Medicare reimbursement rates in effect in calendar years 2013 and 2014 instead of state-established Medicaid reimbursement rates. Generally, state Medicaid reimbursement rates are lower than federally-established Medicare rates. State agencies are working toward submission of state plan amendments outlining how they will implement the rule, including frequency and timing of payments. The timing of these submissions varies by state. Upon submission, CMS will approve, disapprove or request additional information about the plans. There are still many unanswered questions regarding the attestation process that is required to qualify for the enhanced payments as well as whether certain services under state specific programs are eligible for the enhanced payments. Given the uncertainty surrounding the implementation process, eligibility of certain services under state specific programs and the timing and frequency of any payments, at this time we cannot predict with any assurance the ultimate impact of the rule on us. The rule also remains subject to continuing legislative scrutiny, including efforts by Congress to amend or repeal a number of its provisions.

Federal and state agencies are expected to continue to implement provisions of the Affordable Care Act and to develop regulations following the Supreme Court’s decision. However, given the complexity and the number of changes expected as a result of the Affordable Care Act, as well as the implementation timetable for many of them, we cannot predict the ultimate impacts of the Affordable Care Act as they may not be known for several years. The Affordable Care Act also remains subject to continuing legislative scrutiny, including efforts by Congress to amend or repeal a number of its provisions. As a result, we cannot predict with any assurance the ultimate effect of the Affordable Care Act on our Company, nor can we provide any assurance that its provisions will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

Geographic Coverage

During 2012, 2011 and 2010, approximately 59%, 58% and 55%, respectively, of our net patient service revenue was generated by operations in our five largest states. During 2012, our five largest states consisted of Texas, North Carolina, Florida, Georgia and California. During 2011 and 2010, our five largest states consisted of Texas, North Carolina, Florida, Georgia, and Washington. During 2012, 2011 and 2010, our operations in Texas accounted for approximately 24%, 21% and 22%, respectively, of our net patient service revenue.

Payor Mix

We bill payors for professional services provided by our affiliated physicians to our patients based upon rates for specific services provided. Our billed charges are substantially the same for all parties in a particular geographic area regardless of the party responsible for paying the bill for our services. We determine our net patient service revenue based upon the difference between our gross fees for services and our estimated ultimate collections from payors. Net patient service revenue differs from gross fees due to (i) managed care payments at contracted rates, (ii) government-sponsored healthcare program reimbursements at government-established rates, (iii) various reimbursement plans and negotiated reimbursements from other third-parties, and (iv) discounted and uncollectible accounts of private-pay patients.

Our payor mix is composed of contracted managed care, government, principally Medicaid and Medicare, other third-parties and private-pay patients. We benefit from the fact that most of the medical services provided in the NICU are classified as emergency services, a category typically classified as a covered service by managed care payors.

The following is a summary of our payor mix, expressed as a percentage of net patient service revenue, exclusive of administrative fees, for the periods indicated:

The payor mix shown in the table above is not necessarily representative of the amount of services provided to patients covered under these plans. For example, the gross amount billed to patients covered under government programs for the years ended December 31, 2012, 2011 and 2010 represented approximately 55%, 54% and 54%, respectively, of our total gross patient service revenue. These percentages of gross revenue and the percentages of net revenue provided in the table above include the payor mix impact of acquisitions completed through December 31, 2012. On a same-unit basis, however, the gross amount billed to patients covered under government programs for the years ended December 31, 2012, 2011 and 2010 represented approximately 56%,

55% and 55%, respectively, of our total gross patient service revenue. Same units are those units at which we provided services for the entire current period and the entire comparable period.

Quarterly Results

We have historically experienced and expect to continue to experience quarterly fluctuations in net patient service revenue and net income. These fluctuations are primarily due to the following factors:

•

There are fewer calendar days in the first and second quarters of the year, as compared to the third and fourth quarters of the year. Because we provide services in NICUs on a 24-hours-a-day basis, 365 days a year, any reduction in service days will have a corresponding reduction in net patient service revenue.

•

The majority of physician services provided by our office-based and anesthesia practices consist of office visits and scheduled procedures that occur during business hours. As a result, volumes at those practices fluctuate based on the number of business days in each calendar quarter.

•

A significant number of our employees and our associated professional contractors, primarily physicians, exceed the level of taxable wages for social security during the first and second quarters of the year. As a result, we incur a significantly higher payroll tax burden and our net income is lower during those quarters.

We have significant fixed operating costs, including physician compensation, and, as a result, are highly dependent on patient volume and capacity utilization of our affiliated professional contractors to sustain profitability. Additionally, quarterly results may be affected by the timing of acquisitions and fluctuations in patient volume. As a result, the operating results for any quarter are not necessarily indicative of results for any future period or for the full year. Our unaudited quarterly results are presented in further detail in Note 16 to the Consolidated Financial Statements in this Form 10-K.

Application of Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires estimates and assumptions that affect the reporting of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Note 2 to our Consolidated Financial Statements provides a summary of our significant accounting policies, which are all in accordance with GAAP. Certain of our accounting policies are critical to understanding our Consolidated Financial Statements because their application requires management to make assumptions about future results and depends to a large extent on management’s judgment, because past results have fluctuated and are expected to continue to do so in the future.

We believe that the application of the accounting policies described in the following paragraphs is highly dependent on critical estimates and assumptions that are inherently uncertain and highly susceptible to change. For all of these policies, we caution that future events rarely develop exactly as estimated, and the best estimates routinely require adjustment. On an ongoing basis, we evaluate our estimates and assumptions, including those discussed below.

Revenue Recognition

We recognize patient service revenue at the time services are provided by our affiliated physicians. Almost all of our patient service revenue is reimbursed by government-sponsored healthcare programs and third-party insurance payors. Payments for services rendered to our patients are generally less than billed charges. We monitor our revenue and receivables from these sources and record an estimated contractual allowance to properly account for the anticipated differences between billed and reimbursed amounts. Accordingly, patient service revenue is presented net of an estimated provision for contractual adjustments and uncollectibles. Management estimates allowances for contractual adjustments and uncollectibles on accounts receivable based upon historical experience and other factors, including days sales outstanding (“DSO”) for accounts receivable,

evaluation of expected adjustments and delinquency rates, past adjustments and collection experience in relation to amounts billed, an aging of accounts receivable, current contract and reimbursement terms, changes in payor mix and other relevant information. Contractual adjustments result from the difference between the physician rates for services performed and the reimbursements by government-sponsored healthcare programs and insurance companies for such services. The evaluation of these historical and other factors involves complex, subjective judgments. On a routine basis, we compare our cash collections to recorded net patient service revenue and evaluate our historical allowance for contractual adjustments and uncollectibles based upon the ultimate resolution of the accounts receivable balance. These procedures are completed regularly in order to monitor our process of establishing appropriate reserves for contractual adjustments. We have not recorded any material adjustments to prior period contractual adjustments and uncollectibles in the years ended December 31, 2012, 2011 or 2010.

DSO is one of the key factors that we use to evaluate the condition of our accounts receivable and the related allowances for contractual adjustments and uncollectibles. DSO reflects the timeliness of cash collections on billed revenue and the level of reserves on outstanding accounts receivable. Any significant change in our DSO results in additional analyses of outstanding accounts receivable and the associated reserves. We calculate our DSO using a three-month rolling average of net patient service revenue. Our net patient service revenue, net income and operating cash flows may be materially and adversely affected if actual adjustments and uncollectibles exceed management’s estimated provisions as a result of changes in these factors. As of December 31, 2012, our DSO was 48.4 days. We had approximately $873.0 million in gross accounts receivable outstanding at December 31, 2012, and considering this outstanding balance, based on our historical experience, a reasonably likely change of 0.5% to 1.5% in our estimated collection rate would result in an impact to net patient service revenue of approximately $4.4 million to $13.1 million. The impact of this change does not include adjustments that may be required as a result of audits, inquiries and investigations from government authorities and agencies and other third-party payors that may occur in the ordinary course of business. See Note 15 to our Consolidated Financial Statements in this Form 10-K.

Professional Liability Coverage

We maintain professional liability insurance policies with third-party insurers on a claims-made basis, subject to self-insured retention, exclusions and other restrictions. Our self-insured retention under our professional liability insurance program is maintained primarily through a wholly owned captive insurance subsidiary. We record liabilities for self-insured amounts and claims incurred but not reported based on an actuarial valuation using historical loss information, claim emergence patterns and various actuarial assumptions. Liabilities for claims incurred but not reported are not discounted. The average lag period from the date a claim is reported to the date it reaches final settlement is approximately three and one half years, although the facts and circumstances of individual claims could result in lag periods that vary from this average. Our actuarial assumptions incorporate multiple complex methodologies to determine the best liability estimate for claims incurred but not reported and the future development of known claims, including methodologies that focus on industry trends, paid loss development, reported loss development and industry-based expected pure premiums. The most significant assumptions used in the estimation process include the use of loss development factors to determine the future emergence of claim liabilities, the use of frequency and trend factors to estimate the impact of economic, judicial and social changes affecting claim costs, and assumptions regarding legal and other costs associated with the ultimate settlement of claims. The key assumptions used in our actuarial valuations are subject to constant adjustments as a result of changes in our actual loss history and the movement of projected emergence patterns as claims develop. We evaluate the need for professional liability insurance reserves in excess of amounts estimated in our actuarial valuations on a routine basis, and as of December 31, 2012, based on our historical experience, a reasonably likely change of 4.0% to 8.0% in our estimates would result in an increase or decrease to net income of approximately $1.9 million to $3.7 million. However, because many factors can affect historical and future loss patterns, the determination of an appropriate professional liability reserve involves complex, subjective judgment, and actual results may vary significantly from estimates.

Goodwill

We record acquired assets, including identifiable intangible assets and liabilities at their respective fair values, recording to goodwill the excess of cost over the fair value of the net assets acquired. We test goodwill for impairment at a reporting unit level on an annual basis. The testing for impairment is completed using a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, a second step is performed to determine the amount of any impairment loss. We use income and market-based valuation approaches to determine the fair value of our reporting units. These approaches focus on discounted cash flows and market multiples based on our market capitalization to derive the fair value of a reporting unit. We also consider the economic outlook for the healthcare services industry and various other factors during the testing process, including hospital and physician contract changes, local market developments, changes in third-party payor payments, and other publicly available information.

Uncertain Tax Positions

We account for uncertainty in income taxes in accordance with the accounting guidance for uncertain tax positions. This guidance prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also requires policy disclosures regarding penalties and interest and disclosures regarding increases and decreases in uncertain tax positions as a result of tax positions taken in a current or prior period, settlements with taxing authorities and any lapse of an applicable statute of limitations. Additional qualitative discussion is required for any tax position that may result in a significant increase or decrease in uncertain tax positions within a 12-month period from our reporting date. Accounting for uncertain tax positions under this guidance requires significant judgment and analyses as well as assumptions about future events. Future changes to our analyses and assumptions related to uncertain tax positions may have a material impact on our Consolidated Financial Statements.

Other Matters

Other significant accounting policies, not involving the same level of measurement uncertainties as those discussed above, are nevertheless important to an understanding of our Consolidated Financial Statements. For example, our Consolidated Financial Statements are presented on a consolidated basis with our affiliated professional contractors because we or one of our subsidiaries have entered into management agreements with our affiliated professional contractors meeting the “controlling financial interest” criteria set forth in accounting guidance for consolidations. Our management agreements are further described in Note 2 to our Consolidated Financial Statements in this Form 10-K. The policies described in Note 2 often require difficult judgments on complex matters that are often subject to multiple sources of authoritative guidance and are frequently reexamined by accounting standards setters and regulators. See “New Accounting Pronouncements” below for matters that may affect our accounting policies in the future.

Year Ended December 31, 2012 as Compared to Year Ended December 31, 2011

Our net patient service revenue increased $228.4 million, or 14.4%, to $1.82 billion for the year ended December 31, 2012, as compared to $1.59 billion for 2011. Of this $228.4 million increase, $179.0 million, or 78.4%, was attributable to revenue generated from acquisitions completed after December 31, 2010. Same-unit net patient service revenue increased $49.4 million, or 3.2%, for the year ended December 31, 2012. The change in same-unit net patient service revenue was the result of an increase of $29.9 million, or 1.9%, from higher overall patient service volumes and a net increase in revenue of approximately $19.5 million, or 1.3%, related to net reimbursement-related factors. The increase in revenue of $29.9 million from higher patient service volumes includes an increase of $24.2 million in neonatal and other services, including newborn nursery services and hearing screens and a net increase of $5.7 million from volume growth in our anesthesiology and maternal-fetal medicine services, partially offset by a decline in pediatric cardiology services. The net increase in revenue of $19.5 million related to reimbursement-related factors was primarily due to continued improvements in managed care contracting, an increase in the administrative fees received from our hospital partners due to the expansion of our services resulting from internal growth and the flow through of revenue from modest price increases, partially offset by a decrease in revenue caused by an increase in the percentage of our patients being enrolled in government-sponsored programs. Same units are those units at which we provided services for the entire current period and the entire comparable period.

Practice salaries and benefits increased by $160.5 million, or 16.5%, to $1.13 billion for the year ended December 31, 2012, as compared to $970.4 million for 2011. This $160.5 million increase was primarily attributable to increased costs associated with new physicians and other staff to support acquisition-related growth and growth at existing units, of which $121.9 million was related to salaries and $38.6 million was related to benefits and incentive compensation.

Practice supplies and other operating expenses increased $5.0 million, or 7.5%, to $71.8 million for the year ended December 31, 2012, as compared to $66.8 million for 2011. The increase was primarily attributable to practice supply, rent and other costs related to our acquisitions.

General and administrative expenses include all billing and collection functions and all other salaries, benefits, supplies and operating expenses not specifically related to the day-to-day operations of our physician group practices. General and administrative expenses increased $23.1 million, or 13.6%, to $193.5 million for the year ended December 31, 2012, as compared to $170.4 million for 2011. This increase of $23.1 million is attributable to the overall growth of the Company including acquisition-related growth. General and administrative expenses as a percentage of net patient service revenue were 10.7% for the years ended December 31, 2012 and 2011, and grew at a rate slower than the rate of revenue growth.

Depreciation and amortization expense increased by $5.5 million, or 21.8%, to $30.8 million for the year ended December 31, 2012, as compared to $25.3 million for 2011. The increase was primarily attributable to the amortization of intangible assets related to acquisitions and the depreciation of fixed asset additions.

Income from operations increased $34.1 million, or 9.6%, to $389.5 million for the year ended December 31, 2012, as compared to $355.4 million for 2011. Our operating margin was 21.4% for the year ended December 31, 2012, as compared to 22.4% for 2011. This decrease of 94 basis points was primarily due to an increase in operating expenses during the year ended December 31, 2012 as compared to the year ended December 31, 2011, as well as the variability in margins due to the mix of practices acquired after December 31, 2010.

We recorded net interest expense of $1.3 million for the year ended December 31, 2012, as compared to $2.1 million for 2011. The decrease in net interest expense was primarily due to lower outstanding borrowings on our Line of Credit as well as a lower effective interest rate on borrowings under our Line of Credit, market value increases in the investments underlying our deferred compensation arrangements and an increase in interest income, partially offset by an increase in fees related to our Line of Credit. Interest expense for the years ended December 31, 2012 and 2011 consisted primarily of interest charges, commitment fees and amortized debt costs related to our Line of Credit and accretion expense related to our contingent consideration liabilities.

Our effective income tax rate was 37.9% for the year ended December 31, 2012, as compared to 38.3% for 2011.

Net income increased by 10.5% to $240.9 million for the year ended December 31, 2012, as compared to $218.0 million for 2011.

Diluted net income per common and common equivalent share was $4.85 on weighted average shares outstanding of 49.7 million for the year ended December 31, 2012, as compared to $4.47 on weighted average shares outstanding of 48.8 million for 2011. The increase of 0.9 million in our weighted average shares outstanding during 2012 is primarily due to the exercise of employee stock options, the vesting of restricted stock and the issuance of shares under our employee stock purchase plan (“Stock Purchase Plan.”)

Year Ended December 31, 2011 as Compared to Year Ended December 31, 2010

Our net patient service revenue increased $186.7 million, or 13.3%, to $1.59 billion for the year ended December 31, 2011, as compared to $1.40 billion for 2010. Of this $186.7 million increase, $140.1 million, or 75.0%, was attributable to revenue generated from acquisitions completed after December 31, 2009. Same-unit net patient service revenue increased $46.6 million, or 3.5%, for the year ended December 31, 2011. The change in same-unit net patient service revenue was the result of a net increase in revenue of approximately $32.7 million, or 2.5%, related to net reimbursement-related factors and an increase of $13.9 million, or 1.0%, from higher overall patient service volumes across our specialties. The net increase in revenue of $32.7 million related to reimbursement-related factors was primarily due to continued improvements in managed care contracting, an increase in the administrative fees received from our hospital partners due to the expansion of our services resulting from internal growth and the flow through of revenue from modest price increases. The increase in revenue of $13.9 million from higher patient service volumes includes an increase of $9.8 million

from volume growth in our anesthesiology and pediatric cardiology services and an increase of $4.2 million in neonatal and other services, including hearing screens and newborn nursery services. Volume in our maternal-fetal medicine services was essentially flat. Same units are those units at which we provided services for the entire current period and the entire comparable period.

Practice salaries and benefits increased by $115.5 million, or 13.5%, to $970.4 million for the year ended December 31, 2011, as compared to $854.9 million for 2010. This $115.5 million increase was primarily attributable to increased costs associated with new physicians and other staff to support acquisition-related growth and growth at existing units, of which $83.2 million was related to salaries and $32.3 million was related to benefits and incentive compensation.

Practice supplies and other operating expenses increased $9.3 million, or 16.2%, to $66.8 million for the year ended December 31, 2011, as compared to $57.5 million for 2010. The increase was attributable to rent, practice supply and other costs of $5.9 million related to our acquisitions and increases in practice supplies and other costs of $3.4 million at our existing units.

General and administrative expenses include all billing and collection functions and all other salaries, benefits, supplies and operating expenses not specifically related to the day-to-day operations of our physician group practices. General and administrative expenses increased $16.1 million, or 10.4%, to $170.4 million for the year ended December 31, 2011, as compared to $154.3 million for 2010. This increase of $16.1 million is attributable to the overall growth of the Company, of which $5.9 million was attributable to acquisition-related growth. General and administrative expenses as a percentage of net patient service revenue decreased to 10.7% for the year ended December 31, 2011 from 11.0% for the year ended December 31, 2010 and grew at a rate slower than the rate of revenue growth.

Depreciation and amortization expense increased by $3.3 million, or 15.2%, to $25.3 million for the year ended December 31, 2011, as compared to $22.0 million for 2010. Depreciation expense for the year ended December 31, 2011 includes a $4.5 million increase attributable to the amortization of intangible assets related to acquisitions and the depreciation of fixed asset additions. Depreciation and amortization expense for the year ended December 31, 2010 included accelerated amortization of approximately $1.2 million related to the termination of a hospital contract associated with a prior acquisition.

Income from operations increased $42.5 million, or 13.6%, to $355.4 million for the year ended December 31, 2011, as compared to $312.9 million for 2010. Our operating margin was 22.4% for the year ended December 31, 2011, as compared to 22.3% for 2010.

We recorded net interest expense of $2.1 million for the year ended December 31, 2011, as compared to $1.8 million for 2010. The increase in net interest expense was primarily due to market value declines in the investments underlying our deferred compensation arrangements, an increase in fees related to our Line of Credit and accretion related to our contingent consideration liabilities, partially offset by a decrease in interest expense due to a lower effective interest rate on borrowings under our Line of Credit. Interest expense for the years ended December 31, 2011 and 2010 consisted primarily of interest charges, commitment fees and amortized debt costs related to our Line of Credit and accretion expense related to our contingent consideration liabilities.

Our effective income tax rate was 38.3% for the year ended December 31, 2011, as compared to 34.9% for 2010. Our effective income tax rate for 2010 reflects a $10.9 million reduction in our income tax provision during the third quarter of 2010 resulting from the resolution of certain matters that were under review with taxing authorities. Excluding the favorable impact of the tax matters resolution, our effective income tax rate was 38.4% for the year ended December 31, 2010. We believe that excluding the favorable impact from the tax matters resolution provides a more meaningful comparison of our effective income tax rate.

Net income increased by 7.6% to $218.0 million for the year ended December 31, 2011, as compared to $202.7 million for 2010. Our net income for 2010 includes a $10.9 million increase related to a reduction in our

income tax provision resulting from the resolution of certain matters that were under review with taxing authorities. Excluding the favorable impact of the tax matters resolution, our net income of $218.0 million for the year ended December 31, 2011 increased by 13.7% as compared to $191.8 for the year ended December 31, 2010. We believe that excluding the favorable impact from the tax matters resolution provides a more meaningful comparison of our net income.

Diluted net income per common and common equivalent share was $4.47 on weighted average shares outstanding of 48.8 million for the year ended December 31, 2011, as compared to $4.26 on weighted average shares outstanding of 47.6 million for 2010. Diluted net income per common and common equivalent share for 2010 reflects a $10.9 million reduction in our income tax provision, or $0.23 per common and common equivalent share, resulting from the resolution of certain matters that were under review with taxing authorities. Excluding the favorable impact of the tax matters resolution, our diluted net income per common and common equivalent share was $4.03 for the year ended December 31, 2010. We believe that excluding the favorable impact from the tax matters resolution provides a more meaningful comparison of our diluted net income per common and common equivalent share. The increase of 1.2 million in our weighted average shares outstanding during 2011 is primarily due to the exercise of employee stock options, the vesting of restricted stock and the issuance of shares under our Stock Purchase Plan.

LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 2012, we had $21.3 million of cash and cash equivalents on hand as compared to $18.6 million at December 31, 2011. Additionally, we had working capital of $90.7 million at December 31, 2012, an increase of $7.7 million from our working capital of $83.0 million at December 31, 2011. This net increase in working capital is primarily due to year-to-date earnings, net borrowings on our Line of Credit and proceeds from the issuance of common stock under our stock incentive and stock purchase plans, offset by the use of funds for practice acquisitions and contingent purchase price payments.

We generated cash flow from operating activities of $325.7 million, $271.0 million and $240.6 million for the years ended December 31, 2012, 2011 and 2010, respectively. The net increase in cash flow provided from operating activities for the year ended December 31, 2012, as compared to the year ended December 31, 2011, was primarily due to: (i) a net increase in cash flow related to our accounts receivable, primarily due to improved cash collections at our existing units and (ii) improved operating results.

During the year ended December 31, 2012, accounts receivable increased by $17.7 million, as compared to an increase of $49.0 million for 2011. The net change in the increase of accounts receivable is due to improvements in cash collections at existing units, partially offset by increases in accounts receivable related to recent acquisitions.

Our accounts receivable are principally due from managed care payors, government payors, and other third-party insurance payors. We track our collections from these sources, monitor the age of our accounts receivable, and make all reasonable efforts to collect outstanding accounts receivable through our systems, processes and personnel at our corporate and regional billing and collection offices. We use customary collection practices, including the use of outside collection agencies, for accounts receivable due from private pay patients when appropriate. Almost all of our accounts receivable adjustments consist of contractual adjustments due to the difference between gross amounts billed and the amounts allowed by our payors. Any amounts written off related to private pay patients are based on the specific facts and circumstances related to each individual patient account.

Days sales outstanding (“DSO”) is one of the key factors that we use to evaluate the condition of our accounts receivable and the related allowances for contractual adjustments and uncollectibles. DSO reflects the timeliness of cash collections on billed revenue and the level of reserves on outstanding accounts receivable. Our

DSO was 48.4 days at December 31, 2012 as compared to 52.3 days at December 31, 2011. Our DSO improved by 3.9 days, primarily as a result of improvements in cash collections at existing units as well as the continued integration of our recent acquisitions. See Application of Critical Accounting Policies and Estimates—Revenue Recognition for more information on our DSO.

Our cash flow from operating activities is significantly affected by the payment of physician incentive compensation. A large majority of our affiliated physicians participate in our performance-based incentive compensation program and almost all of the payments due under the program are made annually in the first quarter. As a result, we typically experience negative cash flow from operations in the first quarter of each year and fund our operations during this period with cash on hand or funds borrowed under our Line of Credit. In addition, during the first quarter of each year, we use cash to make any discretionary matching contributions for participants in our qualified contributory savings plans.

Cash flow provided from operating activities for the year ended December 31, 2011 was affected by: (i) a net increase in cash flow from operations related to changes in the components of our accounts payable and accrued expenses, consisting primarily of changes in our accrued incentive compensation liability and changes in the current portion of our reserves for uncertain tax positions; and (ii) improved operating results; partially offset by (iii) a reduction in cash flow related to higher accounts receivable balances; and (iv) a net decrease in cash flow related to changes in our income tax liabilities, resulting primarily from higher estimated tax payments. Cash flow provided from operating activities for the year ended December 31, 2010 was affected by: (i) a net decrease in cash flow from operations related to changes in the components of our accounts payable and accrued expenses; and (ii) a reduction in cash flow from operations related to higher accounts receivable balances; partially offset by (iii) a net improvement in cash flow related to changes in our income tax liabilities, primarily due to the timing of our estimated quarterly tax payments; and (iv) improved operating results.

During the year ended December 31, 2012, our net cash used in investing activities of $460.5 million included physician practice acquisition payments and contingent consideration payments of $441.0 million, capital expenditures of $14.5 million and net purchases of $5.0 million related to the purchase and maturity of investments. Our acquisition payments were primarily related to the purchase of 16 physician practices, including eight anesthesiology practices, two maternal-fetal medicine practices, two pediatric cardiology practices, one neonatal practice, and three other pediatric subspecialty practices. Our capital expenditures were for medical equipment, computer and office equipment, software, leasehold and other improvements and furniture and fixtures at our office-based practices and our corporate and regional offices. Under the current accounting guidance for business combinations, payments of contingent consideration liabilities related to acquisitions completed prior to January 1, 2009 are presented as cash flows from investing activities. Payments of contingent consideration liabilities related to acquisitions completed after January 1, 2009 are presented as cash flows from financing activities.

During the year ended December 31, 2012, our net cash provided by financing activities of $137.5 million consisted primarily of net borrowings on our Line of Credit of $115.0 million, proceeds from the exercise of employee stock options and the issuance of common stock under our stock purchase plans of $28.8 million and excess tax benefits related to the exercise of employee stock options and the vesting of restricted stock of $6.5 million, partially offset by the payment of $10.2 million for contingent consideration liabilities and payments of $2.4 million for the amendment of our Line of Credit.

In November 2012, we amended and restated our Line of Credit which increased the borrowing capacity thereunder to $800 million from $500 million. The Line of Credit matures in November 2017.

The Line of Credit, which is guaranteed by substantially all of our subsidiaries and affiliated professional contractors, includes (1) a $75 million sub-facility for the issuance of letters of credit and (2) a $37.5 million sub-facility for swingline loans. The Line of Credit may be increased up to $1.0 billion, subject to the satisfaction of specified conditions. At our option, borrowings under the Line of Credit (other than swingline loans) bear interest at (1) the alternate base rate (defined as the highest of (i) the Wells Fargo Bank, National Association prime rate, (ii) the Federal Funds Rate plus 1/2 of 1.00% and (iii) one month LIBOR plus 1.00%) or (2) the LIBOR rate, as

defined in the Line of Credit, plus an applicable margin rate ranging from 0.125% to 0.750% for alternate base rate borrowings and 1.125% to 1.750% for LIBOR rate borrowings, in each case based on our consolidated leverage ratio. Swingline loans bear interest at the alternate base rate plus the applicable margin rate. We are subject to certain covenants and restrictions specified in the Line of Credit, including covenants that require us to maintain a minimum fixed charge coverage ratio and not to exceed a specified consolidated leverage ratio, to comply with laws, and restrict us from paying dividends and making certain other distributions, as specified therein. Failure to comply with these covenants would constitute an event of default under the Line of Credit, notwithstanding our ability to meet our debt service obligations. The Line of Credit includes various customary remedies for the lenders following an event of default.

At December 31, 2012, we had an outstanding principal balance of $144.0 million on our Line of Credit. We also had outstanding letters of credit associated with our professional liability insurance program of $5.5 million which reduced the amount available on our Line of Credit to $650.5 million at December 31, 2012.

At December 31, 2012, we believe we were in compliance, in all material respects, with the financial covenants and other restrictions applicable to us under the Line of Credit. Based on our current expectations, we believe we will be in compliance with these covenants and other restrictions throughout 2013.

The exercise of employee stock options and the purchase of common stock by employees participating in our Stock Purchase Plan generated cash proceeds of $28.8 million, $31.4 million and $22.5 million for the years ended December 31, 2012, 2011 and 2010, respectively. Because stock option exercises and purchases under these plans are dependent on several factors, including the market price of our common stock, we cannot predict the timing and amount of any future proceeds.

We maintain professional liability insurance policies with third-party insurers, subject to self-insured retention, exclusions and other restrictions. We self-insure our liabilities to pay self-insured retention amounts under our professional liability insurance coverage through a wholly owned captive insurance subsidiary. We record liabilities for self-insured amounts and claims incurred but not reported based on an actuarial valuation using historical loss information, claim emergence patterns and various actuarial assumptions. Our total liability related to professional liability risks at December 31, 2012 was $137.0 million, of which $17.5 million is classified as a current liability within accounts payable and accrued expenses in the Consolidated Balance Sheet.

We anticipate that funds generated from operations, together with our current cash on hand and funds available under our Line of Credit, will be sufficient to finance our working capital requirements, fund anticipated acquisitions and capital expenditures, and meet our contractual obligations as described below for at least the next 12 months. During 2013, we plan to invest approximately $400 million in acquisitions, the majority of which we expect to invest within our anesthesiology specialty and the remainder in our neonatal, maternal-fetal, pediatric cardiology and other pediatric subspecialties.

CONTRACTUAL OBLIGATIONS

At December 31, 2012, we had certain obligations and commitments under our Line of Credit, capital leases and operating leases totaling approximately $241.1 million as follows (in thousands):


	Payments Due
Obligation	Total		2013		2014 and 2015		2016 and 2017		2018 and Later
Line of Credit (1)	$	166,823	$	4,680	$	9,360	$	152,783	$	—
Capital leases		334		101		233		—		—
Operating leases		73,952		20,960		28,320		13,757		10,915

	$	241,109	$	25,741	$	37,913	$	166,540	$	10,915

(1)	Amounts include interest payments at the applicable rate as of December 31, 2012 and assumes the amount outstanding at December 31, 2012 will be paid on the maturity date.

Certain of our acquisition agreements contain contingent consideration provisions based on volume and other performance measures over an up to five-year period. Potential payments under these provisions are not contingent upon the future employment of the sellers. As of December 31, 2012, payments of up to $42.9 million may be due through 2017 under all contingent consideration provisions as follows (in thousands):


2013	$	17.0
2014		11.5
2015		9.4
2016		4.4
2017		0.6

	$	42.9

At December 31, 2012, our total liability for uncertain tax positions was $22.1 million, and is included within other liabilities on our Consolidated Balance Sheet. The timing and amount of future cash flows for each year beyond 2012 cannot be reasonably estimated. See Note 11 to our Consolidated Financial Statements in this Form 10-K for more information regarding our uncertain tax positions.

OFF-BALANCE SHEET ARRANGEMENTS

At December 31, 2012, we did not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources.

NEW ACCOUNTING PRONOUNCEMENTS

In May 2011, the accounting guidance related to fair value measurements was amended. The amendment provides guidance and clarification about the application of existing fair value measurements and disclosure requirements. The amendment became effective on January 1, 2012. The adoption of this guidance did not have a material impact on our consolidated financial statements.

In September 2011, the accounting guidance related to goodwill impairment testing was amended to allow a company to first assess qualitative factors to determine whether performing the current two-step process is necessary. Under this option, the calculation of a reporting unit’s fair value is not required unless, as a result of the qualitative assessment, it is more likely than not that the fair value of the reporting unit is less than the unit’s carrying amount. The amendment became effective on January 1, 2012. The adoption of this guidance did not have an impact on our consolidated financial statements.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our Line of Credit is subject to market risk and interest rate changes. Our Line of Credit bears interest at (1) the alternate base rate, which is defined as the highest of (i) the Wells Fargo Bank, National Association prime rate, (ii) the Federal Funds Rate plus 1/2 of 1.000% and (iii) one month LIBOR plus 1.000% or (2) the LIBOR rate, as defined in the Line of Credit, plus, an applicable margin rate ranging from 0.125% to 0.750% for alternate base rate borrowings and 1.125% to 1.750% for LIBOR rate borrowings, in each case based on the Company’s consolidated leverage ratio. The outstanding principal balance on our Line of Credit was $144.0 million at December 31, 2012. Considering the total outstanding balance of $144.0 million, a 1% change in interest rates would result in an impact to income before taxes of approximately $1.4 million per year.

Report of Independent Registered Certified Public Accounting Firm

To the Board of Directors and Shareholders of

MEDNAX, Inc.:

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of MEDNAX, Inc. and its subsidiaries (the “Company”) at December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these consolidated financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting under Item 9A. Our responsibility is to express opinions on these consolidated financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall consolidated financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

MEDNAX, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. General:

The principal business activity of MEDNAX, Inc. (“MEDNAX” or the “Company”) and its subsidiaries is to provide neonatal, maternal-fetal, other pediatric subspecialties and anesthesia physician services. The Company has contracts with affiliated professional associations, corporations and partnerships (“affiliated professional contractors”), which are separate legal entities that provide physician services in certain states and Puerto Rico. The Company and its affiliated professional contractors also have contracts with hospitals and other healthcare facilities to provide physician services, which include (i) fee-for-service contracts, whereby hospitals agree, in exchange for the Company’s services, to authorize the Company and its healthcare professionals to bill and collect the charges for medical services rendered by the Company’s affiliated healthcare professionals, and (ii) administrative fee contracts, whereby the Company is assured a minimum revenue level.

2. Summary of Significant Accounting Policies:

Principles of Presentation

The financial statements include all the accounts of the Company and its subsidiaries combined with the accounts of the affiliated professional contractors with which the Company currently has specific management arrangements. The Company’s agreements with affiliated professional contractors provide that the term of the arrangements are permanent, subject only to termination by the Company, except in the case of gross negligence, fraud or bankruptcy of the Company. The Company has the right to receive income, both as ongoing fees and as proceeds from the sale of its interest in the Company’s affiliated professional contractors, in an amount that fluctuates based on the performance of the affiliated professional contractors and the change in the fair value of the Company’s interest in the affiliated professional contractors. The Company has exclusive responsibility for the provision of all non-medical services required for the day-to-day operation and management of the Company’s affiliated professional contractors and establishes the guidelines for the employment and compensation of the physicians. In addition, the agreements provide that the Company has the right, but not the obligation, to purchase, or to designate a person(s) to purchase, the stock of the Company’s affiliated professional contractors for a nominal amount. Separately, in its sole discretion, the Company has the right to assign its interest in the agreements. Based upon the provisions of these agreements, the Company has determined that the affiliated professional contractors are variable interest entities and that the Company is the primary beneficiary as defined in the accounting guidance for consolidation. All significant intercompany and interaffiliate accounts and transactions have been eliminated.

New Accounting Pronouncements

Accounting Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the

reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions are involved in the calculation of the Company’s allowance for contractual adjustments and uncollectibles on accounts receivable, liabilities for self-insured amounts and claims incurred but not reported related to the Company’s professional liability risks, the fair value of goodwill, and liabilities for uncertain tax positions. Actual results could differ from those estimates.

Segment Reporting

The results of the Company’s operations are aggregated into a single reportable segment for purposes of presenting financial information in accordance with the accounting guidance for segment reporting.

The following table summarizes the Company’s net patient service revenue by specialties and subspecialties (in percentages):


	Years Ended December 31,
	2012			2011			2010
Neonatal and other pediatric subspecialties		56	%		60	%		65	%
Anesthesia		27	%		21	%		16	%
Maternal-fetal		12	%		13	%		13	%
Pediatric cardiology		5	%		6	%		6	%

		100	%		100	%		100	%

Revenue Recognition

Patient service revenue is recognized at the time services are provided by the Company’s affiliated physicians. Almost all of the Company’s patient service revenue is reimbursed by government-sponsored healthcare programs and third-party insurance payors. Payments for services rendered to the Company’s patients are generally less than billed charges. The Company monitors its revenue and receivables from these sources and records an estimated contractual allowance to properly account for the anticipated differences between billed and reimbursed amounts.

Accordingly, patient service revenue is presented net of an estimated provision for contractual adjustments and uncollectibles. The Company estimates allowances for contractual adjustments and uncollectibles on accounts receivable based upon historical experience and other factors, including days sales outstanding (“DSO”) for accounts receivable, evaluation of expected adjustments and delinquency rates, past adjustments and collection experience in relation to amounts billed, an aging of accounts receivable, current contract and reimbursement terms, changes in payor mix and other relevant information. Contractual adjustments result from the difference between the physician rates for services performed and the reimbursements by government-sponsored healthcare programs and insurance companies for such services.

Accounts receivable are primarily amounts due under fee-for-service contracts from third-party payors, such as insurance companies, self-insured employers and patients and government-sponsored healthcare programs geographically dispersed throughout the United States and its territories. Concentration of credit risk relating to accounts receivable is limited by the number, diversity and geographic dispersion of the business units managed by the Company, as well as by the large number of patients and payors, including the various governmental agencies in the states in which the Company provides services. Receivables from government agencies made up approximately 21% and 23% of net accounts receivable at December 31, 2012 and 2011, respectively.

Cash Equivalents

Cash equivalents are defined as all highly liquid financial instruments with maturities of 90 days or less from the date of purchase. The Company’s cash equivalents typically consist of demand deposits, amounts on

deposit in money market accounts, and funds invested in overnight repurchase agreements. Cash equivalent balances may, at certain times, exceed federally insured limits.

Certain cash equivalents carried by the Company are subject to the fair value provisions of the accounting guidance for fair value measurements. See “Fair Value Measurements” below.

Investments

Investments consist of municipal debt securities, federal home loan securities and certificates of deposit. Investments with remaining maturities of less than one year are classified as short-term investments. Investments classified as long-term have maturities of one year to six years.

The Company intends and has the ability to hold its held-to-maturity securities to maturity, and therefore carries such investments at amortized cost in accordance with the provisions of the accounting guidance for investments in debt and equity securities.

Property and Equipment

Property and equipment are recorded at original purchase cost. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the underlying assets. Estimated useful lives are generally 20 years for buildings; three to 10 years for medical equipment, computer equipment, software and furniture; and the lesser of the useful life or the remaining lease term for leasehold improvements and capital leases. Upon sale or retirement of property and equipment, the related cost and accumulated depreciation are eliminated from the respective accounts and any resulting gain or loss is included in earnings.

Business Acquisitions

The Company accounts for business acquisitions as required by the provisions of the accounting guidance for business combinations, which includes provisions that the Company adopted effective January 1, 2009. The guidance retains the underlying concepts of the previous standard such that all business combinations are required to be accounted for at fair value, but changes certain aspects of applying the acquisition method of accounting. The changes also require the Company to expense certain acquisition costs as they are incurred. In accordance with the acquisition method of accounting, any identifiable assets acquired and any liabilities assumed are recognized and measured at their fair values on the acquisition date. If information about facts and circumstances existing as of the acquisition date is incomplete at the end of the reporting period in which a business acquisition occurs, the Company will report provisional amounts for the items for which the accounting is incomplete. The measurement period ends once the Company receives sufficient information to finalize the fair values; however, the period will not exceed one year from the acquisition date. Any material adjustments recognized during the measurement period will be reflected retrospectively in the consolidated financial statements of the subsequent period.

In connection with certain acquisitions, the Company enters into agreements to pay additional cash amounts based on the achievement of certain performance measures for up to five years ending after the acquisition dates. The Company measures this contingent consideration at fair value at the acquisition date for acquisitions completed on or after January 1, 2009 and records such contingent consideration as a liability on the Company’s Consolidated Balance Sheet on the acquisition date. The fair value of each contingent consideration liability is remeasured at each reporting period with any change in fair value recognized as income or expense within continuing operations of the Company’s Consolidated Statements of Income. Contingent consideration liabilities for acquisitions completed prior to January 1, 2009 are not included on the Company’s Consolidated Balance Sheet and are recorded to goodwill as incurred. See Note 6 for more information on the Company’s business acquisitions.

Goodwill and Other Intangible Assets

The Company records acquired assets and liabilities at their respective fair values under the acquisition method of accounting. Goodwill represents the excess of cost over the fair value of the net assets acquired. Intangible assets with finite lives, principally physician and hospital agreements, are recognized apart from goodwill at the time of acquisition based on the contractual-legal and separability criteria established in the accounting guidance for business combinations. Intangible assets with finite lives are amortized on either an accelerated basis based on the annual undiscounted economic cash flows associated with the particular intangible asset or on a straight-line basis over their estimated useful lives. Intangible assets with finite lives are amortized over periods of one to 20 years.

Goodwill is tested for impairment at a reporting unit level on at least an annual basis in accordance with the subsequent measurement provisions of the accounting guidance for goodwill. The Company defines a reporting unit based upon its management structure for services provided in specific regions of the United States. The testing for impairment is completed using a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, a second step is performed to determine the amount of any impairment loss. The Company uses income and market-based valuation approaches to determine the fair value of its reporting units. These approaches focus on discounted cash flows and market multiples based on the Company’s market capitalization to derive the fair value of a reporting unit. The Company also considers the economic outlook for the healthcare services industry and various other factors during the testing process, including hospital and physician contract changes, local market developments, changes in third-party payor payments, and other publicly available information. The Company completed annual impairment tests in the third quarter of each of 2012, 2011 and 2010 and determined that goodwill was not impaired in any of the three years.

Long-Lived Assets

The Company is required to evaluate long-lived assets, including intangible assets subject to amortization, whenever events or changes in circumstances indicate that the carrying value of the assets may not be fully recoverable. The recoverability of such assets is measured by a comparison of the carrying value of the assets to the future undiscounted cash flows before interest charges to be generated by the assets. If long-lived assets are impaired, the impairment to be recognized is measured as the excess of the carrying value over the fair value. Long-lived assets held for disposal are reported at the lower of the carrying value or fair value less disposal costs. The Company does not believe there are any indicators that would require an adjustment to such assets or their estimated periods of recovery at December 31, 2012 pursuant to current accounting standards.

Professional Liability Coverage

The Company maintains professional liability insurance policies with third-party insurers on a claims-made basis, subject to self-insured retention, exclusions and other restrictions. The Company’s self-insured retention under its professional liability insurance program is maintained primarily through a wholly owned captive insurance subsidiary. The Company records an estimate of liabilities for self-insured amounts and claims incurred but not reported based on an actuarial valuation using historical loss information, claim emergence patterns and various actuarial assumptions. Liabilities for claims incurred but not reported are not discounted.

Income Taxes

The Company records deferred income taxes using the liability method, whereby deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse.

The accounting guidance for uncertain tax positions prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a

tax return. The guidance also requires policy disclosures regarding penalties and interest and extensive disclosures regarding increases and decreases in uncertain tax positions as a result of tax positions taken in a current or prior period, settlements with taxing authorities and any lapse of an applicable statute of limitations. Additional qualitative discussion is required for any tax position that may result in a significant increase or decrease in uncertain tax positions within a 12-month period from the Company’s reporting date.

Stock Incentive Plans

The Company grants stock-based awards consisting of restricted and deferred stock and stock options to key employees under its Amended and Restated 2008 Incentive Compensation Plan. In accordance with the accounting guidance for stock-based compensation, the Company measures the cost of employee services received in exchange for stock-based awards based on grant-date fair value and allocates the resulting compensation expense over the corresponding requisite service period using the graded vesting attribution method. The Company also performs analyses to estimate forfeitures of stock-based awards as required by the accounting guidance for stock-based compensation. The Company is required to adjust its forfeiture estimates on at least an annual basis based on the number of awards that ultimately vest.

Net Income Per Share

Basic net income per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common and potential common shares outstanding during the period. Potential common shares consist of outstanding restricted and deferred stock and stock options calculated using the treasury stock method. Under the treasury stock method, the Company includes the assumed excess tax benefits related to the potential exercise or vesting of its stock-based awards using the difference between the average market price for the applicable period less the option price, if any, and the fair value of the stock-based award on the date of grant multiplied by the applicable tax rate.

Fair Value Measurements

In accordance with the accounting guidance for fair value measurements and disclosures, the Company carries its money market funds included in cash and cash equivalents at fair value. In accordance with the three-tier fair value hierarchy under this guidance, the Company determined the fair value using quoted market prices, a Level 1 input as defined under the accounting guidance for fair value measurements. At December 31, 2012 and 2011, the Company’s money market funds had a carrying amount of $11.1 million and $11.6 million, respectively.

The Company also carries the cash surrender value of life insurance related to its deferred compensation arrangements at fair value. The investments underlying the life insurance contracts consist primarily of exchange-traded equity securities and mutual funds with quoted prices in active markets. In accordance with the three-tier fair value hierarchy, the Company determined the fair value using the cash surrender value of the life insurance, a Level 2 input as defined under the accounting guidance for fair value measurements. At December 31, 2012 and 2011, the Company’s cash surrender value of life insurance had a carrying amount of $13.8 million and $12.7 million, respectively.

In addition, the Company carries its contingent consideration liabilities related to acquisitions completed after January 1, 2009 at fair value. In accordance with the three-tier fair value hierarchy, the Company determined the fair value of its contingent consideration liabilities using the income approach with assumed discount rates and payment probabilities. The income approach uses Level 3, or unobservable inputs as defined under the accounting guidance for fair value measurements. At December 31, 2012 and 2011, the Company’s contingent consideration liabilities related to acquisitions completed after January 1, 2009 had a fair value of $37.7 million and $32.4 million, respectively. See Note 6 for more information regarding the Company’s contingent consideration liabilities recorded during the year ended December 31, 2012.

The carrying amounts of cash equivalents, short-term investments, accounts receivable and accounts payable and accrued expenses approximate fair value due to the short maturities of the respective instruments. The carrying values of long-term investments, line of credit and capital lease obligations approximate fair value. If the Company’s line of credit were measured at fair value, it would be categorized as Level 2 in the fair value hierarchy.

4. Accounts Receivable and Net Patient Service Revenue:

Accounts receivable, net consists of the following (in thousands):


	December 31,
	2012			2011
Gross accounts receivable	$	872,962		$	806,418
Allowance for contractual adjustments and uncollectibles		(624,896	)		(576,030)

	$	248,066		$	230,388

Net patient service revenue consists of the following (in thousands):


	Years Ended December 31,
	2012			2011			2010
Gross patient service revenue	$	5,691,790		$	4,851,500		$	4,140,312
Contractual adjustments and uncollectibles		(3,994,924	)		(3,362,081	)		(2,825,827	)
Hospital contract administrative fees		119,746			98,829			87,074

	$	1,816,612		$	1,588,248		$	1,401,559

Accounts receivable of $248.1 million and $230.4 million at December 31, 2012 and 2011, respectively, consist primarily of amounts due from government-sponsored healthcare programs and third-party insurance payors for services provided by the Company’s affiliated physicians.

Net patient service revenue of $1.8 billion, $1.6 billion and $1.4 billion for the years ended December 31, 2012, 2011 and 2010, respectively, consists primarily of gross billed charges for services provided by the Company’s affiliated physicians less an estimated allowance for contractual adjustments and uncollectibles to properly account for the anticipated differences between gross billed charge amounts and expected reimbursement amounts.

The Company’s contractual adjustments and uncollectibles as a percentage of gross patient service revenue vary slightly each year depending on several factors, including improved managed care contracting, changes in reimbursement from state Medicaid programs and other government-sponsored programs, shifts in the

percentage of patient services being reimbursed under government-sponsored programs and annual price increases.

The Company’s annual price increases typically increase contractual adjustments as a percentage of gross patient service revenue. This increase is primarily due to Medicaid and other government-sponsored health care programs that generally provide for reimbursements on a fee-schedule basis rather than on a gross charge basis. When the Company bills these programs, like other payors, on a gross-charge basis, it also increases its provision for contractual adjustments and uncollectibles by the amount of any price increase, resulting in a higher contractual adjustment percentage.

5. Property and Equipment:

Property and equipment consists of the following (in thousands):


	December 31,
	2012			2011
Building	$	22,957		$	22,243

	$	59,738		$	60,530

At December 31, 2012 and 2011, property and equipment includes medical and other equipment held under capital leases of approximately $1.4 million and $1.6 million, and related accumulated depreciation of approximately $1.1 million and $1.1 million, respectively. The Company recorded depreciation expense of approximately $15.8 million, $15.0 million and $13.5 million for the years ended December 31, 2012, 2011 and 2010, respectively.

6. Business Acquisitions:

During 2012, the Company completed the acquisition of 16 physician group practices for total consideration of $451.1 million, consisting of $436.4 million in cash and $14.7 million of contingent consideration. In connection with these acquisitions, the Company recorded goodwill of approximately $414.3 million, other intangible assets consisting primarily of physician and hospital agreements of approximately $48.2 million, fixed assets of approximately $0.6 million, and other liabilities of approximately $12.0 million. These acquisitions expand the Company’s national network of physician practices. The Company expects to improve the results of these physician practices through improved managed care contracting, improved collections, identification of growth initiatives, as well as, operating and cost savings based upon the significant infrastructure it has developed.

The contingent consideration of $14.7 million recorded during 2012 is related to agreements to pay additional amounts based on the achievement of certain performance measures for up to five years ending after the acquisition dates. The accrued contingent consideration for each acquisition was recorded at acquisition-date fair value using the income approach with assumed discount rates ranging from 3.0% to 5.0% over the applicable terms and an assumed payment probability of 100% for each of the applicable years. The range of the undiscounted amount the Company could pay under the contingent consideration agreements that were recorded with a fair value of $14.7 million is between $0 and $15.9 million. In addition, the Company also entered into a $5.0 million contingent consideration agreement for which the probability of the achievement of certain performance measures was deemed to be remote, and therefore the fair value was determined to be zero, resulting in no contingent consideration being recorded.

During 2012, the Company paid approximately $14.8 million for contingent consideration related to certain prior-period acquisitions, of which $11.5 million was accrued as of December 31, 2011. In addition, as of December 31, 2012, the Company accrued approximately $1.3 million for contingent consideration related to a certain prior-period acquisition that was earned as of December 31, 2012.

During 2011, the Company completed the acquisition of 10 physician group practices for total consideration of $159.5 million, consisting of $146.5 million in cash and $13.0 million of contingent consideration. In connection with these acquisitions, the Company recorded goodwill of approximately $138.6 million, other intangible assets consisting primarily of physician and hospital agreements of approximately $22.5 million, fixed assets of approximately $0.4 million, and other liabilities of approximately $2.0 million.

Certain purchase agreements contain contingent consideration provisions based on volume and other performance measures over a three- to five-year period. Potential payments under these provisions are not contingent upon the future employment of the sellers. Under all contingent consideration provisions, payments of up to $42.9 million may be due through 2017, of which $39.0 million is accrued as of December 31, 2012.

The results of operations of the practices acquired in 2012 and 2011 have been included in the Company’s Consolidated Financial Statements from the dates of acquisition. The following unaudited pro forma information combines the consolidated results of operations of the Company on a GAAP basis and the acquisitions completed during 2012 and 2011, including adjustments for pro forma amortization and interest expense, as if the transactions had occurred on January 1, 2011 and January 1, 2010, respectively (in thousands, except per share data):


	Years Ended December 31,
	2012			2011
Net patient service revenue	$	2,015,167		$	1,950,972
Net income (1)		260,485			255,183
Net income per share (2):
Basic	$	5.35		$	5.35
Diluted	$	5.24		$	5.23
Weighted average shares (2):
Basic		48,693			47,706
Diluted		49,691			48,796
Effective tax rate (1):		37.94	%		38.29	%

(1)	The comparison of net income is affected by the change in the effective tax rate. The effective tax rate was 37.94% for the year ended December 31, 2012 as compared to 38.29% for the year ended December 31, 2011.

(2)

The comparison of net income per share is affected by the changes in the number of weighted average shares outstanding in each period. The basic and diluted weighted average shares outstanding for the year ended December 31, 2012 were 48.7 million and 49.7 million, respectively, as compared to 47.7 million and 48.8 million, respectively, for the year ended December 31, 2011.

The pro forma results do not necessarily represent results which would have occurred if the acquisitions had taken place at the beginning of the periods indicated, nor are they indicative of the results of future combined operations.

7. Goodwill and Other Assets:

Goodwill was $2.2 billion and $1.7 billion at December 31, 2012 and 2011, respectively. The change in the carrying amount of goodwill of approximately $418.9 million during the year ended December 31, 2012 is primarily related to the Company’s 2012 acquisitions and contingent consideration payments made in 2012 related to acquisitions completed prior to January 1, 2009 as discussed in Note 6. The Company expects that

approximately $73.2 million of the $418.9 million of goodwill recorded during the year ended December 31, 2012 will be deductible for tax purposes. Goodwill of approximately $145.4 million related to the 2011 acquisitions and contingent consideration payments made in 2011 related to acquisitions completed prior to January 1, 2009 as discussed in Note 6 represent the only changes in the carrying amount of goodwill for the year ended December 31, 2011.

Other assets consist of the following (in thousands):


	December 31,
	2012		2011
Other intangible assets, net	$	98,503	$	65,264
Other assets		19,787		17,828

	$	118,290	$	83,092

At December 31, 2012, other intangible assets consisted of amortizable hospital and other contracts and physician and hospital agreements with gross carrying amounts of approximately $144.8 million, less accumulated amortization of approximately $46.3 million. At December 31, 2011, other intangible assets consisted of amortizable hospital and other contracts and physician and hospital agreements with gross carrying amounts of approximately $96.6 million, less accumulated amortization of approximately $31.3 million.

Amortization expense related to other intangible assets for the years ended December 31, 2012, 2011 and 2010 was approximately $15.0 million, $10.3 million and $8.5 million, respectively. Amortization expense on other intangible assets for the years 2013 through 2017 is expected to be approximately $21.0 million, $18.7 million, $15.5 million, $11.4 million and $6.9 million, respectively. The remaining weighted average amortization period of other intangible assets is 1.9 years. The calculation of the weighted average amortization period includes amortization expense related to years beyond 2017 of approximately $25.0 million.

Other assets of $19.8 million and $17.8 million at December 31, 2012 and 2011, respectively, consist primarily of the cash surrender value of life insurance related to the Company’s deferred compensation arrangements and other long-term assets.

8. Accounts Payable and Accrued Expenses:

Accounts payable and accrued expenses consist of the following (in thousands):


	December 31,
	2012		2011
Accounts payable	$	13,812	$	12,264
Accrued salaries and bonuses		160,495		147,613
Accrued payroll taxes and benefits		36,176		29,443
Accrued professional liability risks		17,466		13,218
Accrued contingent consideration		16,109		12,089
Accrual for uncertain tax positions		—		3,242
Other accrued expenses		11,603		16,666

	$	255,661	$	234,535

The net increase in accrued salaries and bonuses of $12.9 million, from $147.6 million at December 31, 2011 to $160.5 million at December 31, 2012, is primarily due to performance-based incentive compensation accrued during the year ended December 31, 2012, partially offset by the payment of performance-based incentive compensation during the first quarter of 2012. A majority of the Company’s payments for performance-based incentive compensation is paid annually in the first quarter.

9. Accrued Professional Liability:

At December 31, 2012 and 2011, the Company’s total accrued professional liability of $137.0 million and $122.8 million, respectively, includes incurred but not reported loss reserves of $90.6 million and $79.5 million, respectively, and loss reserves for reported claims associated with self-insured retention amounts through the Company’s wholly owned captive insurance subsidiary of $46.4 million and $43.3 million, respectively.

The activity related to the Company’s total accrued professional liability for the years ended December 31, 2012, 2011 and 2010 is as follows (in thousands):


	Years Ended December 31,
	2012			2011			2010
Balance at beginning of year	$	122,847		$	111,662		$	109,628
Provision (adjustment) for losses related to:
Current year		35,441			33,031			27,086
Prior years		(8,119	)		(10,099	)		(11,142	)

Total provision for losses		27,322			22,932			15,944
Claim payments related to:
Current year		(569	)		(221	)		(553	)
Prior years		(12,564	)		(11,526	)		(13,357	)

Total payments		(13,133	)		(11,747	)		(13,910	)

Balance at end of year	$	137,036		$	122,847		$	111,662

The net increases in the Company’s total accrued professional liability for the years ended December 31, 2012 and 2011, are primarily attributable to increases in the current year provision for losses as a result of the increase in the number of physicians insured due to acquisitions and internal growth, offset by claim payments and adjustments to the provision for losses related to prior years resulting from favorable trends in the Company’s claims experience.

10. Line of Credit and Capital Lease Obligations:

On November 19, 2012, the Company entered into an amended and restated credit agreement (“Amended and Restated Line of Credit”) which increased the borrowing capacity thereunder to $800 million from $500 million. The Amended and Restated Line of Credit matures on November 17, 2017.

The Line of Credit, which is guaranteed by substantially all of the Company’s subsidiaries and affiliated professional contractors, includes (1) a $75 million sub-facility for the issuance of letters of credit and (2) a $37.5 million sub-facility for swingline loans. The Line of Credit may be increased up to $1.0 billion, subject to the satisfaction of specified conditions. At the Company’s option, borrowings under the Line of Credit (other than swingline loans) bear interest at (1) the alternate base rate (defined as the highest of (i) the Wells Fargo Bank, National Association prime rate, (ii) the Federal Funds Rate plus 1/2 of 1.000% and (iii) one month LIBOR plus 1.000%) or (2) the LIBOR rate, as defined in the Line of Credit, plus, an applicable margin rate ranging from 0.125% to 0.750% for alternate base rate borrowings and 1.125% to 1.750% for LIBOR rate borrowings, in each case based on the Company’s consolidated leverage ratio. Swingline loans bear interest at the alternate base rate plus the applicable margin rate. The Company is subject to certain covenants and restrictions specified in the Line of Credit, including covenants that require the Company to maintain a minimum fixed charge coverage ratio and not to exceed a specified consolidated leverage ratio, to comply with laws, and restrict the Company from paying dividends and making certain other distributions, as specified therein. Failure to comply with these covenants would constitute an event of default under the Line of Credit, notwithstanding the Company’s ability to meet its debt service obligations. The Line of Credit includes various customary remedies for the lenders following an event of default. At December 31, 2012, the Company believes it was in compliance, in all material respects, with the financial covenants and other restrictions applicable under the Line of Credit.

The Company had $144.0 million in outstanding principal balance under the Line of Credit at December 31, 2012. The Company has outstanding letters of credit associated with its professional liability insurance program which reduced the amount available under the Line of Credit by $5.5 million at December 31, 2012. The weighted average interest rate on the letters of credit was 1.3% at December 31, 2012. At December 31, 2012, the Company had an available balance on the Line of Credit of $650.5 million.

The Company files its tax return on a consolidated basis with its subsidiaries. The remaining affiliated professional contractors file tax returns on an individual basis.

The effective tax rate was 37.94%, 38.29% and 34.86% for the years ended December 31, 2012, 2011 and 2010, respectively. The Company’s effective income tax rate for the year ended December 31, 2010 included a $10.9 million reduction in its income tax provision resulting from a resolution of certain matters that were under review with taxing authorities.

The differences between the effective rate and the United States federal income tax statutory rate are as follows:

The income tax benefit related to the exercise of stock options, the purchase of shares under the Company’s non-qualified employee stock purchase plan and the vesting of restricted stock in excess of amounts recorded as equity compensation expense reduces taxes currently payable and is credited to additional paid-in capital. Such amounts totaled approximately $6.2 million, $7.1 million, and $3.0 million for the years ended December 31, 2012, 2011 and 2010, respectively.

The Company has net operating loss carryforwards for federal and state tax purposes totaling approximately $14.9 million, $9.4 million, and $20.7 million at December 31, 2012, 2011 and 2010, respectively, expiring at various times commencing in 2014. The changes in net operating loss carryforwards in 2012 and 2011 are primarily due to timing differences related to the recognition of income for tax purposes associated with physician practice acquisitions.

As of December 31, 2012, 2011 and 2010, the Company’s liability for uncertain tax positions, excluding accrued interest and penalties, was $13.1 million, $16.2 million and $22.3 million, respectively. The Company had approximately $12.7 million of uncertain tax positions that, if recognized, would favorably impact its effective tax rate at December 31, 2012.

The following table summarizes the activity related to the Company’s liability for uncertain tax positions for the years ended December 31, 2012, 2011 and 2010 (in thousands):


	Years Ended December 31,

Balance at end of year	$	13,072		$	16,165		$	22,290

During the years ended December 31, 2012 and 2011, the Company decreased its liability for uncertain tax positions by a total of $3.1 million and $6.1 million, respectively, which is primarily related to reclassifications of certain temporary differences to deferred taxes payable.

The Company includes interest and penalties related to income tax liabilities in income tax expense. The Company recognized $0.3 million, $0.4 million and $1.7 million, respectively, of interest and penalties related to income tax liabilities during the years ended December 31, 2012, 2011 and 2010. At December 31, 2012 and 2011, the Company’s accrued liability for interest and penalties related to income tax liabilities totaled $9.0 million and $8.7 million, respectively.

At December 31, 2012, the Company’s total liability for uncertain tax positions of $22.1 million is included in other liabilities as presented in the Company’s Consolidated Balance Sheet. At December 31, 2011, accounts payable and accrued expenses and other liabilities as presented in the Company’s Consolidated Balance Sheet include $3.2 million and $21.7 million, respectively, related to the Company’s total liability for uncertain tax positions of $24.9 million.

The Company anticipates that its liability for uncertain tax positions will be increased over the next 12 months by additional taxes of approximately $1.1 million.

The Company is currently subject to U.S. Federal and various state income tax examinations for the tax years 2004 through 2011.

13. Stock Incentive Plans and Stock Purchase Plan:

On May 10 2012, the Company’s shareholders approved the Amended and Restated 2008 Incentive Compensation Plan (the “Amended and Restated 2008 Incentive Plan”). The amendments increased the number of shares of common stock reserved for delivery under the Amended and Restated 2008 Incentive Plan as well as extended the expiration date to 10 years from the effective date of approval. The Amended and Restated 2008 Incentive Plan provides for grants of stock options, stock appreciation rights, restricted stock, deferred stock, and other stock-related awards and performance awards that may be settled in cash, stock or other property. As provided in the Amended and Restated 2008 Incentive Plan, no additional grants can be made from the Company’s prior incentive plans, except that new awards will be permitted under the 2004 Incentive Compensation Plan (the “2004 Incentive Plan”) to the extent that shares previously granted under the 2004 Incentive Plan are forfeited, expire or terminate. Under the Amended and Restated 2008 Incentive Plan, a total of 5,029,717 shares were available for the granting of awards as of May 10, 2012. Collectively, the Company’s prior incentive plans and the Amended and Restated 2008 Incentive Plan are referred to as the Stock Incentive Plans.

Under the Amended and Restated 2008 Incentive Plan, options to purchase shares of common stock may be granted at a price not less than the fair market value of the shares on the date of grant. The options must be exercised within 10 years from the date of grant and generally become exercisable on a pro rata basis over a three-year period from the date of grant. The Company issues new shares of its common stock upon exercise of its stock options. Restricted stock awards generally vest over periods of three years upon the fulfillment of specified service-based conditions and in certain instances performance-based conditions. Deferred stock awards vest on a cliff basis over a term of five years upon the fulfillment of specified service-based and performance-based conditions or upon the satisfaction of specified performance-based conditions through December 31, 2018. The Company recognizes compensation expense related to its restricted stock and deferred stock awards ratably over the corresponding vesting periods. At December 31, 2012, the Company had approximately 4.3 million shares available for future grants and awards under its Stock Incentive Plans.

Under the Company’s 1996 Non-Qualified Employee Stock Purchase Plan, as amended (the “Non-Qualified Plan”), employees are permitted to purchase the Company’s common stock at 85% of market value on January 1st, April 1st, July 1st and October 1st of each year. In accordance with the provisions of the accounting guidance for stock-based compensation, the Company recognizes stock-based compensation expense for the 15% discount received by participating employees. During the year ended December 31, 2012, 131,598 shares were issued under the Non-Qualified Plan. At December 31, 2012, the Company had approximately 423,500 shares reserved for issuance under the Non-Qualified Plan.

The Company recognized approximately $28.4 million, $27.1 million and $25.7 million of stock-based compensation expense related to its Stock Incentive Plans and Stock Purchase Plan during the years ended December 31, 2012, 2011 and 2010, respectively.

The activity related to the Company’s restricted and deferred stock awards and the corresponding weighted average grant-date fair values for the year ended December 31, 2012 are as follows:


	Number of Shares			Weighted Average Fair Value
Non-vested shares at January 1, 2012		978,353		$	59.64
Awarded		465,317		$	60.11
Forfeited		(39,441	)	$	65.06
Vested		(423,331	)	$	54.30

Non-vested shares at December 31, 2012		980,898		$	61.94

The aggregate fair value of the restricted shares that vested during the years ended December 31, 2012, 2011 and 2010 was approximately $23.0 million, $19.0 million and $14.4 million, respectively.

The weighted average grant-date fair value of restricted and deferred stock awards that were granted during the years ended December 31, 2012, 2011 and 2010 was $60.11, $70.99 and $54.90, respectively.

At December 31, 2012, the total stock-based compensation cost related to non-vested restricted and deferred stock remaining to be recognized as compensation expense over a weighted-average period of approximately 1.4 years was $27.2 million.

The Company uses the Black-Scholes Model to estimate the fair value of each stock option on the date of grant. The Company did not grant any stock options during 2012. The weighted average grant-date fair values for stock options granted during the years ended December 31, 2011 and 2010 were $23.27 and $18.89, respectively, which were calculated using the following weighted average assumptions for expected volatility, expected life, risk-free interest rate and dividend yield:


	Years Ended December 31,
	2011	2010
Expected volatility	35%	35%
Expected life—officers (in years)	4.5	4.5
Expected life—other employees (in years)	3.5	3.5
Risk-free interest rate	1.9%	2.1% to 2.3%
Dividend yield	0%	0%

Expected volatility is estimated using sequential periods of historical price data related to the Company’s common stock. The Company assigns expected lives and corresponding risk-free interest rates to two separate homogenous employee groups consisting of officers and all other employees. The Company evaluates the estimated expected lives assigned to its two employee groups, officers and other employees, using historical exercise data, taking into consideration the impact of partial life cycle data, contractual term and post-vesting cancellations. The risk-free interest rates used are based on the published U.S. Treasury yield curve in effect at the time of the grant for instruments with a similar life. The dividend yield reflects the Company’s dividend yield at the date of grant.

The activity and certain other information related to the Company’s stock option awards for the year ended December 31, 2012 are as follows:


	Number of Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2012		2,053,573		$	45.10
Granted		—			—
Canceled		(5,794	)	$	68.56
Exercised		(528,135	)	$	39.33			$	18.1

Outstanding at December 31, 2012		1,519,644		$	47.02		4.1	$	49.4

Exercisable at December 31, 2012		1,474,539		$	46.46		3.9	$	48.8

The aggregate intrinsic value of stock options exercised during the years ended December 31, 2012, 2011 and 2010 was $18.1 million, $14.1 million and $9.1 million, respectively.

At December 31, 2012, the total stock-based compensation cost related to non-vested stock options remaining to be recognized as compensation expense over a weighted-average period of approximately 0.9 years was $0.2 million.

The net excess tax benefit recognized in additional paid-in capital related primarily to stock options and restricted stock for the years ended December 31, 2012, 2011 and 2010 was approximately $6.2 million, $7.1 million and $3.0 million, respectively. The cash proceeds received from the exercise of stock options for the years ended December 31, 2012, 2011 and 2010 were approximately $20.8 million, $24.5 million and $16.4 million, respectively.

14. Retirement Plans:

The Company maintains three qualified contributory savings plans as allowed under Section 401(k) of the Internal Revenue Code and Section 1165(e) of the Puerto Rico Income Tax Act of 1954 (the “401(k) Plans”). The 401(k) Plans permit participant contributions and allow elective and, in certain situations, non-elective Company contributions based on each participant’s contribution or a specified percentage of eligible wages. Participants may defer a percentage of their annual compensation subject to the limits defined in the 401(k) Plans. The Company recorded an expense of $24.8 million, $20.3 million and $18.2 million for the years ended December 31, 2012, 2011 and 2010, respectively, primarily related to the 401(k) Plans.

15. Commitments and Contingencies:

The Company expects that audits, inquiries and investigations from government authorities and agencies will occur in the ordinary course of business. Such audits, inquiries and investigations and their ultimate resolutions, individually or in the aggregate, could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows and the trading price of its common stock. The Company has not included an accrual for these matters as of December 31, 2012 in its Consolidated Financial Statements, as the variables affecting any potential eventual liability depend on the currently unknown facts and circumstances that arise out of, and are specific to, any particular future audit, inquiry and investigation and cannot be reasonably estimated at this time.

In the ordinary course of business, the Company becomes involved in pending and threatened legal actions and proceedings, most of which involve claims of medical malpractice related to medical services provided by the Company’s affiliated physicians. The Company’s contracts with hospitals generally require the Company to indemnify them and their affiliates for losses resulting from the negligence of the Company’s affiliated physicians. The Company may also become subject to other lawsuits which could involve large claims and significant defense costs. The Company believes, based upon a review of pending actions and proceedings, that the outcome of such legal actions and proceedings will not have a material adverse effect on its business, financial condition or results of operations. The outcome of such actions and proceedings, however, cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows and the trading price of its common stock.

Although the Company currently maintains liability insurance coverage intended to cover professional liability and certain other claims, the Company cannot assure that its insurance coverage will be adequate to cover liabilities arising out of claims asserted against it in the future where the outcomes of such claims are unfavorable. With respect to professional liability risk, the Company generally self-insures a portion of this risk through its wholly owned captive insurance subsidiary. Liabilities in excess of the Company’s insurance coverage, including coverage for professional liability and certain other claims, could have a material adverse effect on the Company’s business, financial condition and results of operations. See “Professional and General Liability Coverage” in Item 1 of this Form 10-K.

The Company leases space for its regional and medical offices, storage space and temporary housing of medical staff. The Company also leases an aircraft. Rent expense for the years ended December 31, 2012, 2011 and 2010 was approximately $23.9 million, $20.8 million, and $19.8 million, respectively.

Future minimum lease payments under non-cancelable operating leases as of December 31, 2012 are as follows (in thousands):


2013	$	20,960
2014		16,268
2015		12,052

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Management’s Annual Report on Internal Control Over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended. The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the Company’s financial statements.

Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements prepared for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of the end of the period covered by this report. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in “Internal Control—Integrated Framework.” Based on our assessment we concluded that, as of the end of the period covered by this report, the Company’s internal control over financial reporting was effective based on those criteria.

The Company’s independent registered certified public accounting firm, PricewaterhouseCoopers LLP, has audited our internal control over financial reporting as of December 31, 2012 as stated in their report which appears on page 49 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

No change in our internal control over financial reporting occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

WHEREAS, Employee has previously served in various management positions with the Employer, it’s predecessor company and their affiliates, and is being promoted to President, Pediatrix Division; and

WHEREAS, Employer and Employee previously entered in an Employment Agreement dated January 1, 2004, as amended (the “Prior Employment Agreement”), which will be cancelled in its entirety with the execution of this Agreement; and

WHEREAS, Employer desires to employ Employee and benefit from Employee’s contributions to Employer; and

WHEREAS, in order to induce Employer to enter into this Agreement on the terms and conditions set forth herein (including an increase in compensation over what was provided under the Prior Employment Agreement), and disclose its trade secrets and confidential information in connection with Employee’s employment by Employer and award from time to time equity based compensation, Employee hereby agrees to be bound by the terms of this Agreement, including the arbitration, non-competition and related restrictive covenants set forth herein.

NOW, THEREFORE, in consideration of the premises and mutual covenants set forth herein, the parties agree as follows:

1. Employment.

1.1. Employment and Term. Employer hereby agrees to employ Employee and Employee hereby agrees to serve Employer on the terms and conditions set forth herein for an “Initial Term” commencing February 13, 2012 (the “Effective Date”) and continuing for a period of one (1) year, unless sooner terminated as hereinafter set forth. Thereafter, the employment of Employee hereunder shall automatically renew for successive one (1) year periods until terminated in accordance herewith. The Initial Term and any automatic renewals shall be referred to as the “Employment Period.”

1.2. Duties of Employee. During the Employment Period, Employee shall serve as President, Pediatrix Division of Employer and perform such duties as are customary to the position Employee holds or as may be assigned to Employee from time to time by Employee’s supervisor

(“Employee’s Supervisor”); provided, that such duties as assigned shall be customary to Employee’s role as an officer of Employer. Employee’s employment shall be full-time and as such Employee agrees to devote substantially all of Employee’s attention and professional time to the business and affairs of Employer. Employee shall perform Employee’s duties honestly, diligently, competently, in good faith and in the best interest of Employer. Employee will devote best efforts to the promotion of the goodwill of Employer and of its employees and affiliates. During the Employment Term, Employer shall promote the proficiency of Employee by, among other things, providing Employee with Confidential Information, specialized professional development programs, and information regarding the organization, administration and operation of Employer. During the Employment Period, Employee agrees that Employee will not, without the prior written consent of Employer (which consent shall not be unreasonably withheld), serve as a director on a corporate board of directors or in any other similar capacity for any institution other than Employer. During the Employment Period, it shall not be a violation of this Agreement to (i) serve on civic or charitable boards or committees, or (ii) deliver lectures, fulfill speaking engagements or teach at educational institutions, so long as such activities have been approved by Employer’s General Counsel and do not interfere with the performance of Employee’s responsibilities as an employee of Employer in accordance with this Agreement, including the restrictions of Section 8 hereof.

1.3. Place of Performance. Employee shall be based at Employer’s offices located in Sunrise, Florida, except for required travel relating to Employer’s Business.

2. Base Salary and Performance Bonus.

2.1. Base Salary.

2.2. Performance Bonus. Employee shall be eligible for an annual bonus of up to the amount set forth on Exhibit B (the “Performance Bonus”). The amount of the actual bonus paid to Employee, if any, shall be based upon the achievement of specific objectives to be developed and agreed upon by Employee and Employee’s Supervisor each year and the performance of Employer. Except in the situations described in Sections 5.2, 5.3, 5.4, 5.5 and 5.7, the Performance Bonus shall only be payable to Employee if Employee is employed with Employer as of the date that the Performance Bonus is paid by Employer. Each Performance Bonus shall be paid in the calendar year immediately following the calendar year in which it is earned, as soon as practicable after the audited financial statements for Employer for the year for which the bonus is earned have been released; provided, however, that if calculation of Employee’s Performance Bonus is not administratively practicable due to events beyond the control of Employee, then Employer may delay payment of the Performance Bonus provided that the payment is made during the first taxable year of Employee in which the calculation of the amount of the payment is administratively practicable.

3. Benefits.

In the event of Employee’s death during the Employment Period, Employer shall notify Employee’s designee or estate of the stock awards held by Employee and the procedures pursuant to which all vested stock options may be exercised and other stock awards may be realized under the terms applicable to such awards. Upon full payment of all amounts required to be paid under this Section 5.3, Employer shall have no further obligation under this Agreement.

Upon payment of the amounts specified under this Sections 5.4 and 5.11, Employer shall have no further obligation under this Agreement.

5.5. Termination by Employee Due to Poor Health. If Employee terminates Employee’s employment under this Agreement pursuant to Section 4.5 hereof, Employer shall pay to Employee any unpaid amounts of Base Salary to the termination date specified in Section 4.5, plus any disability payments otherwise payable by or pursuant to plans provided by Employer, plus any amounts as may be due under Section 5.8 and 5.11 below.

5.7. Termination for Good Reason.

5.8. Expense Reimbursement. Employee shall be entitled to reimbursement for reasonable business expenses incurred prior to the termination date, subject, however to the provisions of Section 3.1.

Except as to incentive stock options granted in accordance with Section 422 of the Internal Revenue Code, after termination of Employee’s employment under this Agreement for any reason other than pursuant to Section 4.1, Employee shall be allowed a period of one hundred eighty (180) days during which to exercise any vested options to purchase MEDNAX, Inc.’s common stock or vested stock appreciation rights and realize any other vested incentive compensation awards that may be granted or made under any Equity Plan; provided, however, that in no event shall the period during which Employee may exercise any vested stock option or vested stock appreciation right be extended pursuant to this Section 5.10 to a date that is later than the earlier of (i) the latest date upon which the stock right could have expired by its original terms under any circumstances or (ii) the tenth (10^th) anniversary of the original date of grant of the stock right.

In addition, notwithstanding any contrary provision in any Equity Plan, in the event Employee’s termination date as a result of a Change in Control (as defined above) occurs within the twelve (12) month period of a Change in Control, any unvested stock options and restricted stock held by Employee on the termination date shall fully vest and in the case of stock options, become immediately exercisable.

5.11. Performance Bonus. In the situations described in Sections 4.1(d), 5.2, 5.3, 5.4, 5.5, and 5.7, upon termination of this Agreement, Employee may be paid, solely in consideration of services rendered by Employee prior to termination, a bonus with respect to Employer’s fiscal year in which the termination date occurs, equal to the Performance Bonus, if any, that would have been payable to Employee, based on Employee and Employer meeting certain goals and objectives, for the fiscal year if Employee’s employment had not been terminated, multiplied by the number of days in the fiscal year prior to and including the date of termination and divided by three hundred sixty five (365). The amount of the Post-Termination Performance Bonus shall be

determined in good faith by Employer in its sole discretion at the time that Employer distributes bonuses to similarly situated employees. Any amount payable under this Section 5.11 shall be paid to Employee when Employer pays performance bonuses to its eligible employees, which shall be in the calendar year following the termination date of this Agreement.

5.12. Section 409A Compliance.

(a) General. It is the intention of both Employer and Employee that the benefits and rights to which Employee could be entitled in connection with termination of employment comply with Section 409A of the Code and the Treasury Regulations and other guidance promulgated or issued thereunder (“Section 409A”), and the provisions of this Agreement shall be construed in a manner consistent with that intention. If Employee or Employer believes, at any time, that any such benefit or right does not so comply, it shall promptly advise the other and shall negotiate reasonably and in good faith to amend the terms of such benefits and rights such that they comply with Section 409A of the Code (with the most limited possible economic effect on Employee and on Employer).

(b) Distributions on Account of Separation from Service. If and to the extent required to comply with Section 409A, no payment or benefit required to be paid under this Agreement on account of termination of Employee’s employment shall be made unless and until Employee incurs a “separation from service”, within the meaning of Section 409A.

(i) If Employee is a “specified employee”, then no payment or benefit that is payable on account of Employee’s “separation from service”, as that term is defined for purposes of Section 409A, shall be made before the date that is six months after Employee’s “separation from service” (or, if earlier, the date of Employee’s death) if and to the extent that such payment or benefit constitutes deferred compensation (or may be nonqualified deferred compensation) under Section 409A and such deferral is required to comply with the requirements of Section 409A. Any payment or benefit delayed by reason of the prior sentence shall be paid out or provided in a single lump sum at the end of such required delay period in order to catch up to the original payment schedule.

(ii) For purposes of this provision, Employee shall be considered to be a “specified employee” if, at the time of his or her separation from service, Employee is a “key employee”, within the meaning of Section 416(i) of the Code, of Employer (or any person or entity with whom Employer would be considered a single employer under Section 414(b) or Section 414(c) of the Code) any stock in which is publicly traded on an established securities market or otherwise.

(iii) Unless otherwise required to comply with Section 409A, a payment or benefit shall not be deferred pursuant to this provision if:

(x) it is not made on account of Employee’s “separation from service”, (y) it is required to be paid no later than within 2¹/₂ months after the end of the taxable year of Employee in which the payment or benefit is no longer subject to a “substantial risk of forfeiture”, as that term is defined for purposes of Section 409A, or (z) the payment satisfies the following requirements: (A) it is being paid or provided due to Employer’s termination of Employee’s employment without Cause (Section 4.4) or Employee’s termination of employment after a Change in Control for the reasons set forth in Section 4.7 hereof, (B) it does not exceed two times the lesser of (1) Employee’s annualized compensation from Employer for the calendar year prior to the calendar year in which the termination of Employee’s employment occurs, and (2) the maximum amount of compensation that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which Employee’s employment terminates, and (C) the payment is required under this Agreement to be paid no later than the last day of the second calendar year following the calendar year in which Employee incurs a “separation from service”.

(d) No Acceleration of Payments. Neither Employer nor Employee, individually or in combination, may accelerate any payment or benefit that is subject to Section 409A, except in compliance with Section 409A and the provisions of this Agreement, and no amount shall be paid prior to the earliest date on which it may be paid without violating Section 409A.

(e) Treatment of Each Installment as a Separate Payment. For purposes of applying the provisions of Section 409A to this Agreement, each separately identified amount to which Employee is entitled under this Agreement shall be treated as a separate payment. In addition, to the extent permissible under Section 409A, any series of installment payments under this Agreement shall be treated as a right to a series of separate payments.

(f) Reimbursements and In-Kind Benefits.

(i) Any reimbursements by Employer to Employee of any eligible expenses pursuant to Section 3.1 or 5.8 of this Agreement, that are not excludible from Employee’s income for Federal income tax purposes (“Taxable Reimbursements”) shall be made on or before the last day of the taxable year of Employee following the year in which the expense was incurred.

(ii) The amount of any Taxable Reimbursements, and the value of any in-kind benefits to be provided to Employee under this Agreement, during any taxable year of Employee shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year of Employee.

(iii) The right to Taxable Reimbursements, or in-kind benefits, shall not be subject to liquidation or exchange for another benefit.

(g) Tax Gross-Ups. Payment of any Gross-Up Payment under Section 5.9 hereof must be made by the end of the taxable year of Employee following the taxable year of Employee in which Employee remits the related taxes.

5.13. Release. Employer shall provide Employee with a general release in the form attached as Exhibit C (subject to such modifications as Employer may reasonably request) within seven (7) days after Employee’s termination date. Payments or benefits to which Employee may be entitled pursuant to this Section 5 (other than any accrued but unpaid Base Salary and employee benefits as of the end of the Employment Period) (the “Severance Amounts”) shall be conditioned upon Employee executing the general release within 21 days after receiving it from Employer and the general release becoming irrevocable upon the expiration of 7 days following the Employee’s execution of it. Payment of the Severance Amounts shall be suspended during the period (the “Suspension Period”) that begins on Employee’s termination date and ends on the date (“Suspension Termination Date”) that is thirty-five (35) days after Employee’s termination date; provided, however, that this suspension shall not apply, and Employer shall be required to provide, any continued health insurance coverage that would be required under Section 5.9 hereof during the Suspension Period. If Employee executes the general release and the general release becomes irrevocable by no later than the Suspension Termination Date, then payment of any Severance Amounts that were suspended pursuant to this provision shall be made in the first payroll period that follows the Suspension Termination Date, and any Severance Amounts that are payable after the Suspension Termination Date shall be paid at the times provided in Section 5.

5.14. Vesting of Incentive Awards. Notwithstanding any contrary provision in this Agreement or any Stock Option or Incentive Compensation Plan then maintained by MEDNAX, Inc., (i) all stock options, stock appreciation rights, restricted stock, and other stock-based awards granted to Employee by MEDNAX, Inc. prior to termination of this Agreement shall continue to vest until fully vested following a termination of Employee’s employment pursuant to Section 4.2 and 4.3.

6. Successors; Binding Agreement.

6.1. Successors. Employer shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) acquiring a majority of Employer’s voting common stock or any other successor to all or substantially all of the business and/or assets of Employer to expressly assume and agree to perform this Agreement in the same manner and to the same extent that Employer would be required to perform it if no such succession had taken place and Employee hereby consents to any such assignment. In such event, “Employer” shall mean Employer as previously defined and any successor to its business and/or assets which executes and delivers the agreement provided for in this Section 6 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law. This Section shall not limit Employee’s ability to terminate this Agreement in the circumstances described in Section 4.7 in the event of a Change in Control of Employer.

6.2. Benefit. This Agreement and all rights of Employee under this Agreement shall inure to the benefit of and be enforceable by Employee’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If Employee should die after the termination date and amounts would have been payable to Employee under this Agreement if Employee had continued to live, including under Section 5 hereof, then such amounts shall be paid to Employee’s devisee, legatee, or other designee or, if there is no such designee, Employee’s estate.

7. Conflicts with Prior Employment Contract. Except as otherwise provided in this Agreement, this Agreement constitutes the entire agreement among the parties pertaining to the subject matter hereof, and supersedes and revokes any and all prior or existing agreements, written or oral, relating to the subject matter hereof, and this Agreement shall be solely determinative of the subject matter hereof.

8. Restrictive Covenants; Confidential Information; Work Product; Injunctive Relief.

8.1. No Material Competition. Employer and Employee acknowledge and agree that a strong relationship and connection exists between Employer and its current and prospective patients, referral sources, and customers as well as the hospitals and healthcare facilities at which it provides professional services. Employer and Employee further acknowledge and agree that the restrictive covenants described in this Section are designed to enforce, and are ancillary to or part of, the promises contained in this Agreement and are reasonably necessary to protect the legitimate interests of Employer in the following: (1) the use and disclosure of the Confidential Information as described in Section 8.4; (2) the professional development activities described in Section 1.2; and (3) the goodwill of the Employer, as promoted by Employee as provided in Section 1.2. The foregoing listing is by way of example only and shall not be construed to be an exclusive or exhaustive list of such interests. Employee acknowledges that the restrictive covenants set forth below are of significant value to Employer and were a material inducement to Employer in agreeing to the terms of this Agreement. Employee further acknowledges that the goodwill and other proprietary interest of Employer will suffer irreparable and continuing damage in the event Employee enters into competition with Employer in violation of this Section.

(a) Employer’s Business. Therefore, Employee agrees that, except with respect to services performed under this Agreement on behalf of Employer, Employee shall not, at any time during the Restricted Period (as defined below), for Employee or on behalf of any other person, persons, firm, partnership, corporation or employer, participate or engage in or own an interest in, directly or indirectly, any individual proprietorship, partnership, corporation, joint venture, trust or other form of business entity, whether as an individual proprietor, partner, joint venturer, officer, director, member, employee, consultant, independent contractor, stockholder, lender, landlord, finder, agent, broker, trustee, or in any manner whatsoever, if such entity or its affiliates is engaged in, directly or indirectly, “Employer’s Business,” as defined on Exhibit A hereto. Employee acknowledges that, as of the date hereof, Employee’s responsibilities will include matters affecting the businesses of Employer listed on Exhibit A. For purposes of this Section 8, the “Restricted Period” shall mean the Employment Period plus (i) twelve (12) months in the event this Agreement is terminated pursuant to Sections 4.1 (a), 4.1 (b), 4.1 (c), 4.1 (d), 4.1(e), 4.7(a), 4.7(b), 4.7(d), or 4.7(e) or (ii) eighteen months in the event the Agreement is terminated for any other reason.

(b) Medical Services. Employee acknowledges that Employee’s duties under this Agreement call for Employee’s active involvement in and management of medical practices owned by affiliates of Employer. Employee further acknowledges that Employer’s affiliates

have a substantial investment in such medical practices and that Employer’s affiliates would be economically injured due to lost income in a material amount in the event Employee competes with Employer’s affiliates in their primary market areas. Accordingly, Employee agrees that Employee shall not, at any time during the Employment Period and for a period of eighteen (18) months immediately following termination of Employee’s employment under this Agreement for any reason, for Employee or on behalf of any other person, persons, firm, partnership, corporation or employer, provide professional medical services in any of the clinical practice areas described as Employer’s Business on Exhibit A within a radius of two (2) miles of a medical practice owned or operated by Employer or its affiliates.

8.2. No Hire. Employee further agrees that Employee shall not, at any time during the Employment Period and for a period of eighteen (18) months immediately following termination of this Agreement for any reason, for Employee or on behalf of any other person, persons, firm, partnership, corporation or employer, employ, or knowingly permit any company or business directly or indirectly controlled by Employee to employ or otherwise engage (a) any person who is a then current employee or independent contractor of Employer or one of its affiliates, or (b) any person who was an employee or independent contractor of Employer or one of its affiliates in the prior six (6) month period, or in any manner seek to induce such persons to leave his or her employment or engagement with Employer or one of its affiliates (including without limitation for or on behalf of a subsequent employer of Employee).

8.3 Non-solicitation. Employee further agrees that Employee shall not, at any time during the Employment Period and for a period of eighteen (18) months immediately following termination of this Agreement for any reason, for Employee or on behalf of any other person, persons, firm, partnership, corporation or employer, solicit or accept business from or take any action that would interfere with, diminish or impair the valuable relationships that Employer or its affiliates have with (i) hospitals or other health care facilities with which Employer or its affiliates have contracts to render professional services or otherwise have established relationships, (ii) patients, (iii) referral sources, (iv) vendors, (v) any other clients of Employer or its affiliates, or (vi) prospective hospitals, patients, referral sources, vendors or clients whose business Employee was aware that Employer or any affiliate of Employer was in the process of soliciting at the time of Employee’s termination (including potential acquisition targets).

8.4. Confidential Information. At all times during the term of this Agreement, Employer shall provide Employee with access to “Confidential Information.” As used in this Agreement, the term “Confidential Information” means any and all confidential, proprietary or trade secret information, whether disclosed, directly or indirectly, verbally, in writing or by any other means in tangible or intangible form, including that which is conceived or developed by Employee, applicable to or in any way related to: (i) patients with whom Employer has a physician/patient relationship; (ii) the present or future business of Employer; or (iii) the research and development of Employer. Without limiting the generality of the foregoing, Confidential Information includes: (a) the development and operation of Employer’s medical practices, including information relating to budgeting, staffing needs, marketing, research, hospital relationships, equipment capabilities, and other information concerning such facilities and operations and specifically including the procedures and business plans developed by Employer for use at the hospitals where Employer conducts its business; (b) contractual arrangements between the Employer and insurers or managed care

associations or other payors; (c) the databases of Employer; (d) the clinical and research protocols of Employer, including coding guidelines; (e) the referral sources of Employer; (f) other confidential information of Employer that is not generally known to the public that gives Employer the opportunity to obtain an advantage over competitors who do not know or use it, including the names, addresses, telephone numbers or special needs of any of its patients, its patient lists, its marketing methods and related data, lists or other written records used in Employer’s business, compensation paid to employees and other terms of employment, accounting ledgers and financial statements, contracts and licenses, business systems, business plan and projections, and computer programs. The parties agree that, as between them, this Confidential Information constitutes important, material, and confidential trade secrets that affect the successful conduct of Employer’s business and its goodwill. Employer acknowledges that the Confidential Information specifically enumerated above is special and unique information and is not information that would be considered a part of the general knowledge and skill Employee has or might otherwise obtain.

Notwithstanding the foregoing, Confidential Information shall not include any information that (i) was known by Employee from a third party source before disclosure by or on behalf of Employer, (ii) becomes available to Employee from a source other than Employer that is not, to Employee’s knowledge, bound by a duty of confidentiality to Employer, (iii) becomes generally available or known in the industry other than as a result of its disclosure by Employee, or (iv) has been independently developed by Employee and may be disclosed by Employee without breach of this Agreement, provided, in each case, that the Employee shall bear the burden of demonstrating that the information falls under one of the above-described exceptions.

Employee agrees that the terms of this Agreement shall be deemed Confidential Information for purposes of this Section. Employee shall keep the terms of this Agreement strictly confidential and will not, without the prior written consent of Employer, disclose the details of this Agreement to any third party in any manner whatsoever in whole or in part, with the exception of Employee’s representatives (such as tax advisors and attorneys) who need to know such information.

Employee agrees that Employee will not at any time, whether during or subsequent to the term of Employee’s employment with Employer, in any fashion, form or manner, unless specifically consented to in writing by Employer, either directly or indirectly, use or divulge, disclose, or communicate to any person, firm or corporation, in any manner whatsoever, any Confidential Information of any kind, nature, or description, subject to applicable law. The parties agree that any breach by Employee of any term of this Section is a material breach of this Agreement and shall constitute “cause” for the termination of Employee’s employment hereunder. In the event that Employee is ordered to disclose any Confidential Information, whether in a legal or a regulatory proceeding or otherwise, Employee shall provide Employer with prompt written notice of such request or order so that Employer may seek to prevent disclosure or, if that cannot be achieved, the entry of a protective order or other appropriate protective device or procedure in order to assure, to the extent practicable, compliance with the provisions of this Agreement. In the case of any disclosure required by law, Employee shall disclose only that portion of the Confidential Information that Employee is ordered to disclose in a legally binding subpoena, demand or similar order issued pursuant to a legal or regulatory proceeding.

All Confidential Information, and all equipment, notebooks, documents, memoranda, reports, files, samples, books, correspondence, lists, other written and graphic records, in any media (including electronic or video) containing Confidential Information or relating to the business of Employer, which Employee shall prepare, use, construct, observe, possess, or control shall be and remain Employer’s sole property (collectively “Employer Property”). Upon termination or expiration of this Agreement, or earlier upon Employer’s request, Employee shall promptly deliver to Employer all Employer Property, retaining none.

8.5. Ownership of Work Product. Employee agrees and acknowledges that (i) all copyrights, patents, trade secrets, trademarks, service marks, or other intellectual property or proprietary rights associated with any ideas, concepts, techniques, inventions, processes, or works of authorship developed or created by Employee during the course of performing work for Employer and any other work product conceived, created, designed, developed or contributed by Employee during the term of this Agreement that relates in any way to Employer’s Business (collectively, the “Work Product”), shall belong exclusively to Employer and shall, to the extent possible, be considered a work made for hire within the meaning of Title 17 of the United States Code. To the extent the Work Product may not be considered a work made for hire owned exclusively by Employer, Employee hereby assigns to Employer all right, title, and interest worldwide in and to such Work Product at the time of its creation, without any requirement of further consideration. Upon request of Employer, Employee shall take such further actions and execute such further documents as Employer may deem necessary or desirable to further the purposes of this Agreement, including without limitation separate assignments of all right, title, and interest in and to all rights of copyright and all right, title, and interest in and to any inventions or patents and any reissues or extensions which may be granted therefore, and in and to any improvements, additions to, or modifications thereto, which Employee may acquire by invention or otherwise, the same to be held and enjoyed by Employer for its own use and benefit, and for the use and benefit of Employer’s successors and assigns, as fully and as entirely as the same might be held by Employee had this assignment not been made.

8.6. Clearance Procedure for Proprietary Rights Not Claimed by Employer. In the event that Employee wishes to create or develop, other than on Employer’s time or using Employer’s resources, anything that may be considered Work Product but to which Employee believes Employee should be entitled to the personal benefit of, Employee agrees to follow the clearance procedure set forth in this Section. Before beginning any such work, Employee agrees to give Employer advance written notice and provide Employer with a sufficiently detailed written description of the work under consideration for Employer to make a determination regarding the work. Unless otherwise agreed in a writing signed by Employer prior to receipt, Employer shall have no obligation of confidentiality with respect to such request or description. Employer will determine in its sole discretion, within thirty (30) days after Employee has fully disclosed such plans to Employer, whether rights in such work will be claimed by Employer. If Employer determines that it does not claim rights in such work, Employer agrees to so notify Employee in writing and Employee may retain ownership of the work to the extent that such work has been expressly disclosed to Employer. If Employer fails to so notify Employee within such thirty (30) day period, then Employer shall be deemed to have agreed that such work is not considered Work Product for purposes of this Agreement. Employee agrees to submit for further review any significant improvement, modification, or adaptation that could reasonably be related to Employer’s Business so that it can be determined whether the improvement, modification, or adaptation relates to the business or interests of Employer. Clearance under this procedure does not relieve Employee of the restrictive covenants set forth in this Section 8.

8.7. Non-Disparagement and Medical Malpractice Cases. For a period of ten (10) years after the termination of this Agreement, Employee will not, directly or indirectly, as an individual or on behalf of a firm, corporation, partnership or other legal entity, make any disparaging or negative comment to any other person or entity regarding Employer or any of its affiliates, agents, attorneys, employees, officers and directors, Employee’s work conditions or circumstances surrounding Employee’s separation from Employer or otherwise impugn or criticize the name or reputation of Employer, its affiliates, agents, attorneys, employees, officers or directors, orally or in writing. Furthermore, for a period of ten (10) years after termination of this Agreement, Employee will not provide Employee’s professional medical opinion as an expert in the review of medical records for medical malpractice cases that are in any way adverse to Employer or any of its affiliates, employees, officers, directors, or patients, regardless of whether Employee’s testimony would be against Employer, its affiliates, employees, officers, directors or an unrelated third party co-defendant. For a period of twelve (12) months after termination of this Agreement, Employee will not provide Employee’s professional medical opinion as an expert in the review of medical records for medical malpractice cases that are in any way adverse to any hospital at which professionals affiliated with Employer provide services.

8.8. Review by Employee. Employee has carefully read and considered the terms and provisions of this Section 8, and having done so, agrees that the restrictions set forth in this Section 8 are fair and reasonably required for the protection of the interests of Employer. In the event that any term or provision set forth in this Section 8 shall be held to be invalid or unenforceable by a court of competent jurisdiction, the parties hereto agree that such invalid or unenforceable term(s) or provision(s) may be severed from this Agreement without, in any manner, affecting the remaining portions hereof. Without limiting other possible remedies available to Employer, Employee agrees that injunctive or other equitable relief will be available to enforce the covenants set forth in this Section, such relief to be without the necessity of posting a bond. In the event that, notwithstanding the foregoing, any part of the covenants set forth in this Section shall be held to be invalid, overbroad, or unenforceable by an arbitration panel or a court of competent jurisdiction, the parties hereto agree that such invalid, overbroad, or unenforceable provision(s) may be modified or severed from this Agreement without, in any manner, affecting the remaining portions of this Section 8 (all of which shall remain in full force and effect). In the event that any provision of this Section 8 related to time period or areas of restriction shall be declared by an arbitration panel or a court of competent jurisdiction to exceed the maximum time period, area or activities such arbitration panel or court deems reasonable and enforceable, said time period or areas of restriction shall be deemed modified to the minimum extent necessary to make the geographic or temporal restrictions or activities reasonable and enforceable.

8.9. Survival. The provisions of this Section 8 shall survive the termination of this Agreement and Employee’s employment with Employer. The provisions of this Section 8 shall apply during the time Employee is receiving Disability payments from Employer as a result of a termination of this Agreement pursuant to Section 4.2 hereof. In the event of a breach of this Section 8 by Employee, Employer retains the right to terminate any continuing payments to Employee provided for in Section 5 of this Agreement. The provisions of this Section 8 are

expressly intended to benefit and be enforceable by other affiliated entities of Employer, who are express third party beneficiaries hereof. Employee shall not assist others in engaging in any of the activities described in the foregoing restrictive covenants.

9. Arbitration. Any controversy or claim arising out of or relating to this Agreement, or any alleged breach hereof shall be finally determined by binding arbitration before a three member panel, consisting of one member selected by each party hereto, with the third member selected by the first two arbitrators. Each party hereto shall bear the costs of its own nominee, and shall share equally the cost of the third arbitrator and the parties agree that the costs of arbitration shall not be subject to reapportionment by the arbitration panel. The arbitration proceedings shall be held in Sunrise, Florida, unless otherwise mutually agreed by the parties, and shall be conducted in accordance with the American Health Lawyer’s Association Dispute Resolution Service, Rules of Procedure for Arbitration. Judgment on the award rendered by the arbitration panel may be entered and enforced by any court having jurisdiction thereof. Notwithstanding anything herein to the contrary, if the Employer shall require immediate injunctive relief, then the Employer shall be entitled to seek such relief in any court having jurisdiction, and if the Employer elects to do so, the Employee hereby consents to the jurisdiction of the state and federal courts sitting in the State of Florida and to the applicable service of process. Employee hereby waives and agrees not to assert, to the fullest extent permitted by applicable law, any claim that (i) Employee is not subject to the jurisdiction of such courts, (ii) Employee is immune from any legal process issued by such courts and (iii) any litigation or other proceeding commenced in such courts is brought in an inconvenient forum. Any such arbitration shall be treated as confidential by all parties thereto, except as otherwise provided by law or as otherwise necessary to enforce any judgment or order issued by the arbitrators.

10. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Florida without regard to its conflict of laws principles to the extent that such principles would require the application of laws other than the laws of the State of Florida.

11. Notices. Any notice required or permitted to be given under this Agreement shall be in writing and shall be deemed to have been given when delivered by hand or when deposited in the United States mail by registered or certified mail, return receipt requested, postage prepaid, addressed as follows:


		If to Employer:		If to Employee:

		Pediatrix Medical Group, Inc.		Michael D. Stanley, M.D.
		1301 Concord Terrace
		Sunrise, FL 33323
		Attention: General Counsel

or to such other addresses as either party hereto may from time to time give notice of to the other in the aforesaid manner.

12. Benefits: Binding Effect. This Agreement shall be for the benefit of and binding upon the parties hereto and their respective heirs, personal representatives, legal representatives, successors and, where applicable, assigns. Notwithstanding the foregoing, Employee may not assign the rights or benefits hereunder without the prior written consent of Employer.

13. Severability. The invalidity of any one or more of the words, phrases, sentences, clauses or sections contained in this Agreement shall not affect the enforceability of the remaining portions of this Agreement or any part thereof, all of which are inserted conditionally on their being valid in law, and, in the event that any one or more of the words, phrases, sentences, clauses or sections contained in this Agreement shall be declared invalid, this Agreement shall be construed as if such invalid word or words, phrase or phrases, sentence or sentences, clause or clauses, or section or sections had not been inserted. If such invalidity is caused by length of time or size of area, or both, the otherwise invalid provision will be considered to be reduced to a period or area, which would cure such invalidity.

14. Waivers. The waiver by either party hereto of a breach or violation of any term or provision of this Agreement shall not operate nor be construed as a waiver of any subsequent breach or violation.

15. Damages. Nothing contained herein shall be construed to prevent Employer or Employee from seeking and recovering from the other damages sustained by either or both of them as a result of a breach of any term or provision of this Agreement. In the event that either party hereto brings suit for the collection of any damages resulting from, or the injunction of any action constituting, a breach of any of the terms or provisions of this Agreement, then the party found to be at fault shall pay all reasonable court costs and attorneys’ fees of the other, whether such costs and fees are incurred in a court of original jurisdiction or one or more courts of appellate jurisdiction.

16. No Third Party Beneficiary. Except as provided in Section 8.9, nothing expressed or implied in this Agreement is intended, or shall be construed, to confer upon or give any person (other than the parties hereto and, in the case of Employee, Employee’s heirs, personal representative(s) and/or legal representative) any rights or remedies under or by reason of this Agreement. No agreements or representations, oral or otherwise, express or implied, have been made by either party with respect to the subject matter of this Agreement which agreements or representations are not set forth expressly in this Agreement, and this Agreement supersedes any other employment agreement between Employer and Employee.

17. Assignment. This Agreement may be assigned by Employer upon notice to Employee.

EXHIBIT A

BUSINESS OF EMPLOYER

As of the date hereof, Employer, directly or through its affiliates, provides professional medical services and all aspects of practice management services in medical practice areas that include, but are not limited to, the following (collectively referred to herein as “Employer’s Business”):

(1)	Neonatology, including hospital well baby care;

(2)	Maternal-Fetal Medicine, including general obstetrics services;

(3)	Pediatric Cardiology;

(4)	Pediatric Intensive Care, including Pediatric Hospitalist Care;

(5)	Hearing screening services;

(6)	Anesthesiology and pain management.

References to Employer’s Business in this Agreement shall include such other medical service lines, practice management services and other businesses entered into by Employer after the date hereof but during the term of this Agreement; provided, that to be considered a part of Employer’s Business, Employer must have engaged in such other service line, practice management service or other business at least six (6) months prior to the termination date of this Agreement. For purposes of this Exhibit A, businesses of Employer shall include the businesses conducted by Employer’s subsidiaries, entities under common control and affiliates as defined under Rule 144 of the Securities Act of 1933, as amended. Such affiliates shall include the professional corporations and associations whose operating results are consolidated with Employer for financial reporting purposes.

Notwithstanding the foregoing, Employer acknowledges and agrees to the following exceptions and clarifications regarding the scope of Employer’s Business.

A. Practice Management Services. Employer acknowledges that, as of the date hereof, Employer’s Business relates to the delivery of both professional and practice management services in the forgoing practice areas. Therefore, as of the date hereof, Employer acknowledges that it would not be a violation of Section 8.1 of the Agreement for Employee to provide services to a practice management company (such as a billing company or management services organization (MSO)) if such practice management company is not owned by, affiliated with (as defined under Rule 144 of the Securities Act of 1933, as amended) or under common control with a health care provider that provides services in the medical services areas included in Employer’s Business. Subject to paragraph C below, the provisions of this paragraph shall not apply to the extent that, after the date hereof, Employer enters into a business that involves the delivery of practice management services to unrelated third parties.

B. Hospital Services. Employer and Employee acknowledge that, as of the date hereof, Employer does not currently operate hospitals, hospital systems or universities. Nevertheless, the businesses of hospitals, hospital systems and universities would be the same as Employer’s Business where such hospitals, hospital systems or universities provide or contract with others to provide

some or all of the medical services included in Employer’s Business. Therefore, the parties desire to clarify their intent with respect to the limitations on Employee’s ability to work for or contract with others to provide services for a hospital, hospital system or university after termination of this Agreement. Section 8.1 shall not be deemed to restrict Employee’s ability to work for a hospital, hospital system or university if the hospital, hospital system or university does not provide any of the medical services included in Employer’s Business. Furthermore, even if a hospital, hospital system or university provides medical services that are included in Employer’s Business, Employee may work for such hospital, hospital system or university if (i) Employee has no direct supervisory responsibility for or involvement in the hospital’s, hospital system’s or university’s medical services that are Employer’s Business, and (ii) Employee would not otherwise violate Section 8.1(b). Finally, Employer agrees that Employee may hold direct supervisory responsibility for or be involved in the medical services of a hospital, hospital system or university that are included in Employer’s Business so long as such hospital, hospital system or university is located at least ten (10) miles from a medical practice owned or operated by Employer or its affiliate. Subject to paragraph C below, the provisions of this paragraph shall not apply to the extent that, after the date hereof, Employer enters into the business of operating a hospital or hospital system.

C. De Minimus Exception. Employer agrees that a medical service line (other than those listed in items 1 through 5 above), practice management service or other business entered into by Employer shall not be considered to be a part of Employer’s Business if such medical service line, practice management service or other business constitutes less than Fifteen Million Dollars ($15,000,000) of Employer’s annual revenues.

D. Certain Ownership Interests. It shall not be deemed to be a violation of Section 8.1(a) for Employee to: (i) own, directly or indirectly, one percent (1%) or less of a publicly-traded entity; or (ii) own, directly or indirectly, less than five percent (5%) of a privately-held business or company, if Employee is at all times a passive investor with no board representation, management authority or other special rights to control operations of such business or company.

EXHIBIT B

COMPENSATION

Base Salary: $450,000.00.

Performance Bonus: Up to Seventy-Five Percent (75%) of Employee’s Base Salary based upon Employee meeting certain goals and objectives, as set forth by Employee’s Supervisor.

EXHIBIT C

FORM OF RELEASE

GENERAL RELEASE OF CLAIMS

1. _______________ (“Employee”), for himself and his family, heirs, executors, administrators, legal representatives and their respective successors and assigns, in exchange for the consideration received pursuant to Section 5.[ ] of the Employment Agreement to which this release is attached as Exhibit A (the “Employment Agreement”), does hereby release and forever discharge Pediatrix Medical Group, Inc. (“Employer”), its subsidiaries, affiliated companies, successors and assigns, and its current or former directors, officers, employees, shareholders or agents in such capacities (collectively with Employer, the “Released Parties”) from any and all actions, causes of action, suits, controversies, claims and demands whatsoever, for or by reason of any matter, cause or thing whatsoever, whether known or unknown including, but not limited to, all claims under any applicable laws arising under or in connection with Employee’s employment or termination thereof, whether for tort, breach of express or implied employment contract, wrongful discharge, intentional infliction of emotional distress, or defamation or injuries incurred on the job or incurred as a result of loss of employment. Employee acknowledges that Employer encouraged him to consult with an attorney of his choosing, and through this General Release of Claims encourages him to consult with his attorney with respect to possible claims under the Age Discrimination in Employment Act (“ADEA”) and that he understands that the ADEA is a Federal statute that, among other things, prohibits discrimination on the basis of age in employment and employee benefits and benefit plans. Without limiting the generality of the release provided above, Employee expressly waives any and all claims under ADEA that he may have as of the date hereof. Employee further understands that by signing this General Release of Claims he is in fact waiving, releasing and forever giving up any claim under the ADEA as well as all other laws within the scope of this paragraph 1 that may have existed on or prior to the date hereof. Notwithstanding anything in this paragraph 1 to the contrary, this General Release of Claims shall not apply to (i) any actions to enforce rights to receive any payments or benefits which may be due Employee pursuant to Section 5.[ ] of the Employment Agreement, or under any of Employer’s employee benefit plans, (ii) any rights or claims that may arise as a result of events occurring after the date this General Release of Claims is executed, (iii) any indemnification rights Employee may have as a former officer or director of Employer or its subsidiaries or affiliated companies, (iv) any claims for benefits under any directors’ and officers’ liability policy maintained by Employer or its subsidiaries or affiliated companies in accordance with the terms of such policy, and (v) any rights as a holder of equity securities of Employer.

2. Employee represents that he has not filed against the Released Parties any complaints, charges, or lawsuits arising out of his employment, or any other matter arising on or prior to the date of this General Release of Claims, and covenants and agrees that he will never individually or with any person file, or commence the filing of, any charges, lawsuits, complaints or proceedings with any governmental agency, or against the Released Parties with respect to any of the matters released by Employee pursuant to paragraph 1 hereof (a “Proceeding”); provided, however, Employee shall not have relinquished his right to commence a Proceeding to challenge whether Employee knowingly and voluntarily waived his rights under ADEA.

3. Employee hereby acknowledges that Employer has informed him that he has up to twenty-one (21) days to sign this General Release of Claims and he may knowingly and voluntarily waive that twenty-one (21) day period by signing this General Release of Claims earlier. Employee also understands that he shall have seven (7) days following the date on which he signs this General Release of Claims within which to revoke it by providing a written notice of his revocation to Employer.

4. Employee acknowledges that this General Release of Claims will be governed by and construed and enforced in accordance with the internal laws of the State of Delaware applicable to contracts made and to be performed entirely within such State.

5. Employee acknowledges that he has read this General Release of Claims, that he has been advised that he should consult with an attorney before he executes this general release of claims, and that he understands all of its terms and executes it voluntarily and with full knowledge of its significance and the consequences thereof.

6. This General Release of Claims shall take effect on the eighth day following Employee’s execution of this General Release of Claims unless Employee’s written revocation is delivered to Employer within seven (7) days after such execution.
