ANNUAL REPORT ON FORM 10-K
FOR THE YEAR ENDED DECEMBER 31, 20142015

Table of Contents

PART I

Forward-Looking Statements

        This annual report on Form 10-K contains forward-looking statements within the meaning of the federal securities laws. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. Forward-looking statements include statements preceded by, followed by or that include the words "may," "could," "would," "should," "believe," "expect," "anticipate," "plan," "target," "estimate," "project," "intend" and similar expressions. These statements include, among others, statements regarding our expected business outlook, anticipated financial and operating results, our business strategy and means to implement our strategy, our objectives, the amount and timing of capital expenditures, the likelihood of our success in expanding our business, financing plans, budgets, working capital needs and sources of liquidity.

        Forward-looking statements are only predictions and are not guarantees of performance. These statements are based on our management's beliefs and assumptions, which in turn are based on currently available information. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding our services, the expansion of our services, competitive conditions and general economic conditions. These assumptions could prove inaccurate. Forward-looking statements also involve known and unknown risks and uncertainties, which could cause actual results to differ materially from those contained in any forward-looking statement. Many of these factors are beyond our ability to control or predict. Such factors include, but are not limited to, the following:

•

changes in government reimbursement for our services due to the implementation of healthcare reform legislation, deficit reduction measures, and/or new payment policies (including, for example, the expiration of the moratorium limiting the full application of the 25 Percent Rule that would reduce our Medicare payments for those patients admitted to a long term acute care hospital from a referring hospital in excess of an applicable percentage admissions threshold) may result in a reduction in net operating revenues, an increase in costs and a reduction in profitability;



•

the impact of the Bipartisan Budget Act of 2013 (the "BBA of 2013"), which establishes new payment limits for Medicare patients who do not meet specified criteria, may result in a reduction in net operating revenues and profitability of our long term acute care hospitals;



•

the failure of our specialty hospitals to maintain their Medicare certifications may cause our net operating revenues and profitability to decline;



•

the failure of our facilities operated as "hospitals within hospitals" to qualify as hospitals separate from their host hospitals may cause our net operating revenues and profitability to decline;



•

a government investigation or assertion that we have violated applicable regulations may result in sanctions or reputational harm and increased costs;



•

acquisitions or joint ventures may prove difficult or unsuccessful, use significant resources or expose us to unforeseen liabilities;



•

our plans and expectations related to the acquisition of Concentra, including expectations regarding the expected capital expenditures related to the acquisition, and our ability to realize anticipated synergies;



•

private third-party payors for our services may undertake future cost containment initiatives that could limit our future net operating revenues and profitability;



•

the failure to maintain established relationships with the physicians in the areas we serve could reduce our net operating revenues and profitability;

2014, 2015, all of the 129127 specialty hospitals we operated were accredited by either The Joint Commission or the AOA. Some of our IRFs had also received accreditation from CARF. See " — "—Government Regulations — Licensure — Regulations—Licensure—Accreditation." We also believe we develop brand loyalty in the local areas we serve by demonstrating our quality of care.

        Our treatment programs, which are continuously reassessed and updated, benefit patients because they give our clinicians access to the best practices and protocols that we have found to be most effective in treating various conditions such as respiratory failure, non-healing wounds, brain and spinal cord injuries, strokes and neuromuscular disorders. In addition, we combine or modify these programs to provide a treatment plan tailored to meet our patients' unique needs. We measure the outcomes and successes of our patients' recovery in order to provide the best possible patient care and service.

        The quality of the patient care we provide is continually monitored using several measures, including clinical outcomes data and analyses and patient satisfaction surveys. Quality measures from our hospitals are collected at our corporate offices and used to create monthly, quarterly and annual reports. In order to benchmark ourselves against other hospitals, we collect our clinical and patient satisfaction information and compare it to national standards and the results of other healthcare organizations. We report to the states in which our hospitals are located certain quality measures that are required to be reported under state laws. We also report to the Centers for Medicare & Medicaid Services, or "CMS","CMS," the quality data required to be reported by specialty hospitals. See " — "—Government Regulations — Regulations—Other Medicare Regulations — Regulations—Medicare Quality Reporting."

        Reduce Operating Costs.    We continually seek to improve operating efficiency and reduce costs at our specialty hospitals by standardizing operations and centralizing key administrative functions. These initiatives include:

•

centralizing administrative functions such as accounting, finance, treasury, payroll, legal, operational support, human resources, compliance and billing and collection;



•

standardizing management information systems to aid in accounting, billing, collections and data capture and analysis; and



•

centralizing sourcing and contracting to receive discounted prices for pharmaceuticals, medical supplies and other commodities used in our operations.

        Increase Commercial Volume.    We have focused on continued expansion of our relationships with commercial insurers to increase our volume of patients with commercial insurance in our specialty hospitals. We believe that commercial payors seek to contract with our hospitals because we offer our patients high-quality, cost-effective care at more attractive rates than general acute care hospitals. We also offer commercial enrollees customized treatment programs not typically offered in general acute care hospitals.

        Develop Specialty Hospitals.    Since our inception in 1997, we have internally developed 7173 specialty hospitals. The BBA of 2013 reinstated thehospitals, including 68 LTCHs and five IRFs. There is currently a moratorium through September 30, 2017 on the establishment and classification of new LTCHs, LTCH satellite facilities and LTCH beds in existing LTCHs or satellite facilities, beginning January 1, 2015 through September 30, 2017. The Protecting Access tosee "—Government Regulations—Long Term Acute Care Hospital Medicare Act of 2014 (the "PAMA") advanced the commencement date ofReimbursement—Moratorium on New LTCHs, LTCH Satellite Facilities and LTCH beds." We may open additional LTCHs that met exceptions under the new moratorium from January 1, 2015and we continue to April 1, 2014. The PAMA includes exceptions to the moratorium that are applicable to the establishment and classification ofdevelop new LTCHs or LTCH satellites facilities currently under development. The new moratorium will not apply to LTCHs or LTCH satellites facilities that: (1) began their qualifying period to become an LTCH on or before April 1, 2014; (2) had a binding written agreement as of April 1, 2014 with an unrelated party for construction, renovation, or lease for an LTCH and have expended, before April 1, 2014, at least 10% of the estimated cost of the project (or, if less, $2,500,000); or (3) had obtained a certificate of need on or before April 1, 2014. The new moratorium provides no exceptions for increases in the number of certified beds in existing LTCHs and LTCH satellites. Further, in accordance with the requirements of guidance issued on October 10, 2014 by the Survey and Certification Group at CMS's

Table of Contents

Central Office, any LTCH that establishes a new satellite, based upon meeting the criteria for an exception to the moratorium, must reduce beds elsewhere in the LTCH in order to operate beds in the new satellite location.IRFs through our joint venture relationships. In addition, we may considerare currently pursuing international development opportunities.

        Pursue Joint Ventures with Large Health Care Systems.    By leveraging the experience of our senior management and development team, we believe that we are well positioned to expand our portfolio of joint ventured operations. When we identify joint venture opportunities, our development team conducts an extensive review of the area's referral patterns and commercial insurance rates to determine the general reimbursement trends and payor mix. Once discussions commence with a health care system, we refine the specific needs of a joint venture, which could include working capital, the construction of new space or the leasing and renovation of existing space. A joint venture typically consists of us and the health care system contributing certain post acute care businesses into a newly formed entity. We typically function as the manager and hold either a majority or minority ownership interest. We believe we improve the joint venture by bringing clinical expertise, adding clinical programs that attract commercial payors, and implementing our standardized resource management programs, which may increase the financial performance of the joint venture.

        Pursue Opportunistic Acquisitions.    In addition to our development and joint venture initiatives, we may grow our network of specialty hospitals through opportunistic acquisitions. When we acquire a hospital or a group of hospitals, a team of our professionals is responsible for formulating and executing an integration plan. We seek to improve financial performance at such facilities by adding clinical programs that attract commercial payors, centralizing administrative functions and implementing our standardized resource management programs.

Outpatient Rehabilitation

        We believe that we are the largest operator of outpatient rehabilitation clinics in the United States based on number of facilities, with 1,0231,038 facilities throughout 31 states and the District of Columbia as of December 31, 2014.2015. Typically, each of our clinics is located in a medical complex or retail location. We also provide medical rehabilitative services to residents and patients of nursing homes, hospitals, schools, assisted living and senior care centers and worksites. As of December 31, 2014,2015, we provided rehabilitative services to approximately 409419 contracted locations in 2730 states and the District of Columbia. Our outpatient rehabilitation segment employed approximately 9,0009,600 people as of December 31, 2014.2015.

        In our clinics and through our contractual relationships, we provide physical, occupational and speech rehabilitation programs and services. We also provide certain specialized programs such as functional programs for work related injuries, hand therapy, post-concussion rehabilitation and athletic training services. The typical patient in one of our clinics suffers from musculoskeletal impairments that restrict his or her ability to perform normal activities of daily living. These impairments are often associated with accidents, sports injuries, work related injuries or post-operative orthopedic and other medical conditions. Our rehabilitation programs and services are designed to help these patients minimize physical and

Table of Contents

cognitive impairments and maximize functional ability. We also provide services designed to prevent short term disabilities from becoming chronic conditions. Our rehabilitation services are provided by our professionals including licensed physical therapists, occupational therapists and speech-language pathologists.

        Outpatient rehabilitation patients are generally referred or directed to our clinics by a physician, employer or health insurer who believes that a patient, employee or member can benefit from the level of therapy we provide in an outpatient setting. We believe that our services are attractive to healthcare payors who are seeking to provide a high-quality and cost-effective care to their enrollees.

        In our outpatient rehabilitation segment, approximately 90%89% of our net operating revenues come from commercial payors, including healthcare insurers, managed care organizations and workers' compensation programs, contract management services and private pay sources. The balance of our reimbursement is derived from Medicare and other government sponsored programs.

        For a description of government regulations and Medicare payments made to our outpatient rehabilitation services see " — "—Government Regulations" and "Management's Discussion and Analysis of Financial Condition and Results of Operations — Operations—Regulatory Changes."

Outpatient Rehabilitation Strategy

        The key elements of our outpatient rehabilitation strategy are to:

        Provide High-Quality Care and Service.    We are focused on providing a high level of service to our patients throughout their entire course of treatment. To measure satisfaction with our service we have developed surveys for both patients and physicians. Our clinics utilize the feedback from these surveys to continuously refine and improve service levels. We believe that by focusing on quality care and offering a high level of customer service we develop brand loyalty in the local areas we serve. This high quality of care and service allows us to strengthen our relationships with referring physicians, employers and health insurers and drive additional patient volume.

        Increase Market Share.    We strive to establish a leading presence within the local areas we serve. To increase our presence, we seek to expand our services and programs and to open new clinics in our existing markets. This allows us to realize economies of scale, heightened brand loyalty and workforce continuity. We are focused on increasing our workers' compensation and commercial/managed care payor mix.

        Expand Rehabilitation Programs and Services.    Through our local clinical directors of operations and clinic managers within their service areas, we assess the healthcare needs of the areas we serve. Based on these assessments, we implement additional programs and services specifically targeted to meet demand in the local community. In designing these programs we benefit from the knowledge we gain through our national network of clinics. This knowledge is used to design programs that optimize treatment methods and measure changes in health status, clinical outcomes and patient satisfaction.

        Optimize the Profitability of our Payor Contracts.    We review payor contracts up for renewal and potential new payor contracts to optimize our profitability. Before we enter into a new contract with a commercial payor, we evaluate it with the aid of our contract management system. We assess potential profitability by evaluating past and projected patient volume, clinic capacity, and expense trends. We create a retention strategy for the top performing contracts and a renegotiation strategy for contracts that do not meet our defined criteria. We believe that our national footprint and our strong reputation enable us to negotiate favorable outpatient contracts with commercial insurers.

        Maintain Strong Employee Relations.    We believe that the relationships between our employees and the referral sources in their communities are critical to our success. Our referral sources, such as physicians and healthcare case managers, send their patients to our clinics based on three factors: the quality of our care, the service we provide and their familiarity with our therapists. We seek to retain and motivate our

Table of Contents

therapists by implementing a performance- basedperformance-based bonus program, a defined career path with the ability to be promoted from within, timely communication on company developments and internal training programs. We also focus on empowering our employees by giving them a high degree of autonomy in determining local area strategy. We seek to identify therapists who are potential business leaders. This management approach reflects the unique nature of each local area in which we operate and the importance of encouraging our employees to assume responsibility for their clinic's performance.

        Pursue Opportunistic Acquisitions.    We may grow our network of outpatient rehabilitation facilities through opportunistic acquisitions. We believe our size and centralized infrastructure allow us to take advantage of operational efficiencies and increase margins at acquired facilities.

Concentra

        We believe that we are the largest provider of occupational health services in the United States based on the number of facilities. We also believe we are the largest private operator of Veterans Administration CBOCs. As of December 31, 2015 we operated 300 medical centers, 138 onsite clinics at employer worksites and 33 CBOCs throughout 43 states. We deliver occupational medicine, consumer health, physical therapy, and veteran's healthcare services in our medical centers, onsite clinics located at the workplaces of our employer customers and our CBOCs. Our Concentra segment employed approximately 8,200 people as of December 31, 2015.

        We offer a range of occupational and consumer health services through our medical centers and onsite clinics. Occupational health services include workers' compensation injury care as well as employer services, clinical testing, wellness programs and preventative care. Consumer health consists of non-employer, patient-directed treatment of injuries and illnesses. Our consumer service offerings include urgent care, wellness programs and preventative care. Our services at the CBOCs include primary care, specialty care, subspecialty care, mental health, and pharmacy benefits.

        Occupational medicine refers to the diagnosis and treatment of work-related injuries (workers' compensation) and preventive and compliance services, including pre-employment, fitness for duty, and post-accident physical examinations and substance abuse screening. Utilization is driven by the needs of labor-intensive industries such as transportation, distribution/warehousing, manufacturing, construction, health care, police/fire and other occupations that have historically posed a higher than average risk of workplace injury or that require a workplace physical. Workers' compensation is the form of insurance that provides medical coverage to employees with work-related illnesses or injuries.

        Workers' compensation is administered on a state-by-state basis and each state is responsible for implementing and regulating its own workers' compensation program. Because workers' compensation benefits are mandated by law and subject to extensive regulation, insurers, third-party administrators and employers do not have the same flexibility to alter benefits as they have with other health benefit programs. In addition, because programs vary by state, it is difficult for insurance companies and multi-state employers to adopt uniform policies to administer, manage and control the costs of benefits across states. As a result, managing the cost of workers' compensation requires approaches that are tailored to the specific regulatory environments in which the employer operates. For the year ended December 31, 2015, approximately 52% of our Concentra segment operating revenues came from workers' compensation.

        In Concentra's occupational health services business, patient bookings and revenues are typically lower in the quarter ended December 31 compared to the other quarters. We believe that decreased patient bookings are caused by fewer work-related injuries and illnesses during the quarter due to our customer's employees being on vacation and our customer's facilities being closed for the holidays.

Concentra Strategy

        The key elements of our Concentra strategy are to:

        Provide High-Quality Care and Service.    We strive to provide a high level of service to our patients and our employer customers. We measure and monitor patient and employer satisfaction and focus on treatment programs to provide the best clinical outcomes in a consistent manner. Our programs and services have proven that aggressive treatment and management of workers injuries can more rapidly restore employees to better health which reduces workers' compensation indemnity claim costs for our employer customers.

        Focus on Occupational Medicine.    Our history as an industry leader in the provision of occupational medicine services provides the platform for Concentra to grow this service offering. Complementary service offerings within occupational medicine will help secure additional growth in this business line.

        Pursue Direct Employer Relationships.    We believe we provide occupational health services in a cost effective manner to our employer customers. By establishing direct relationships with these customers we seek to reduce overall costs of their workers' compensation claims, while improving employee health and getting their employees back to work faster.

        Increase Market Share.    We strive to establish a leading presence within the local areas we serve. To increase our presence, we seek to expand our services and programs and to open new medical centers and employer onsite locations in our existing markets. This allows us to realize economies of scale, heightened brand loyalty and workforce continuity.

        Pursue Opportunistic Acquisitions.    We may grow our network of Concentra medical centers and expand our geographic reach through opportunistic acquisitions. We believe our size and centralized infrastructure allow us to take advantage of operational efficiencies and increase margins at acquired facilities.

Other

        Other activities include our corporate services and certain other minority investments in other healthcare related businesses. These include investments in companies that provide specialized technology, services to healthcare entities and providers of complementary services.

Our Competitive Strengths

        We believe that the success of our business model is based on a number of competitive strengths, including our position as a leading operator in each of our business segments, proven financial performance and strong cash flow, significant scale, experience in completing and integrating acquisitions, ability to capitalize on consolidation opportunities and an experienced management team.

        Leading Operator in Distinct but Complementary Lines of Business.    We believe that we are a leading operator in each of our principal business segments, based on number of facilities in the United States. Our leadership position and reputation as a high-quality, cost-effective healthcare provider in each of our business segments allows us to attract patients and employees, aids us in our marketing efforts to payors and referral sources and helps us negotiate payor contracts. In our specialty hospitalhospitals segment, we operated 113109 LTCHs in 2827 states and 1618 IRFs in eight states at December 31, 2014.2015. We derived approximately 73%63% of net operating revenues from our specialty hospitalhospitals segment, for the year ended December 31, 2014.2015. In our outpatient rehabilitation segment, we operated 1,0231,038 outpatient rehabilitation clinics in 31 states and the District of Columbia at December 31, 2014.2015. We derived approximately 27%22% of net operating revenues from our outpatient rehabilitation segment for the year ended December 31, 2014.2015. In our Concentra segment, we operated 300 medical centers in 38 states at December 31, 2015. We derived

Table of Contents

approximately 15% of net operating revenues from our Concentra segment. With these leading positions in the areas we serve, we believe that we are well-positioned to benefit from the rising demand for medical services due to an aging population in the United States, which will drive growth across our business lines.

        Proven Financial Performance and Strong Cash Flow.    We have established a track record of improving the financial performance of our facilities due to our disciplined approach to revenue growth, expense management and an intense focus on free cash flow generation. This includes regular review of specific financial metrics of our business to determine trends in our revenue generation, expenses, billing and cash collection. Based on the ongoing analysis of such trends, we make adjustments to our operations to optimize our financial performance and cash flow.

        Significant Scale.    By building significant scale in each of our business segments, we have been able to leverage our operating costs by centralizing administrative functions at our corporate office.

        Experience in Successfully Completing and Integrating Acquisitions.    From our inception in 1997 through 2014,2015, we completed seveneight significant acquisitions for approximately $1,104.8 million in aggregate consideration.$2.15 billion, which includes $1.05 billion paid to acquire Concentra. We believe that we have improved the operating performance of these facilities over time by applying our standard operating practices and by realizing efficiencies from our centralized operations and management.

        Experience in Partnering with Large Health Care Systems.    Over the past several years we have partnered with large regional health care systems to provide post acutepost-acute care services. We believe that we provide operating expertise through our experience in operating specialty hospitals and outpatient rehabilitation services to these ventures and have improved and expanded the level of post acutepost-acute care services provided in these communities, as well as the financial performance of these operations.

        Well-Positioned to Capitalize on Consolidation Opportunities.    We believe that we are well-positioned to capitalize on consolidation opportunities within each of our business segments and selectively augment our internal growth. We believe that each of our business segments is fragmented, with many of the nation's LTCHs, IRFs and outpatient rehabilitation facilities being operated by independent operators lacking national or broad regional scope. With our geographically diversified portfolio of facilities in the

Table of Contents

United States, we believe that our footprint provides us with a wide-ranging perspective on multiple potential acquisition opportunities.

        Experienced and Proven Management Team.    Prior to co-founding our company with our current Executive Chairman and Co-Founder, our Vice Chairman and Co-Founder founded and operated three other healthcare companies focused on inpatient and outpatient rehabilitation services. In addition, our senior management team has extensive experience in the healthcare industry. Our President and Chief Executive Officer has more than two decades of management experience in the healthcare industry. Many of our other executives, such as our Chief Operating Officer, our Chief Financial Officer, our General Counsel, our Chief Human Resources Officer and our Chief Accounting Officer, have each served at our company for more than 15 years. In recent years, we have reorganized our operations to expand executive talent and ensure management continuity.

Sources of Net Operating Revenues

        The following table presents the approximate percentages by source of net operating revenue received for healthcare services we provided for the periods indicated:

Government Sources

        Medicare is a federal program that provides medical insurance benefits to persons age 65 and over, some disabled persons, and persons with end-stage renal disease. Medicaid is a federal-state funded program, administered by the states, which provides medical benefits to individuals who are unable to afford healthcare. As of December 31, 2014,2015, we operated 129127 specialty hospitals, 126 of which were certified as Medicare providers and three ofone which werewas in the process of obtaining theirits certification. Our outpatient rehabilitation clinics regularly receive Medicare payments for their services. Additionally, many of our specialty hospitals participate in state Medicaid programs. Amounts received under the Medicare and Medicaid programs are generally less than the customary charges for the services provided. In recent years there have been significant changes made to the Medicare and Medicaid programs. Since a significant portion of our revenues come from patients under the Medicare program, our ability to operate our business successfully in the future will depend in large measure on our ability to adapt to changes in the Medicare program. See "—Government Regulations — Regulations—Overview of U.S. and State Government Reimbursements."

Table of Contents

Non-Government Sources

        Our non-government sources of net operating revenue include insurance companies, workers' compensation programs, health maintenance organizations, preferred provider organizations, other managed care companies and employers, as well as by patients directly. Patients are generally not responsible for any difference between customary charges for our services and amounts paid by Medicare and Medicaid programs, insurance companies, workers' compensation companies,programs, health maintenance organizations, preferred provider organizations and other managed care companies, but are responsible for services not covered by these programs or plans, as well as for deductibles and co-insurance obligations of their coverage. The amount of these deductibles and co-insurance obligations has increased in recent years. Collection of amounts due from individuals is typically more difficult than collection of amounts due from government or commercial payors.

Employees

        As of December 31, 2014,2015, we employed approximately 31,40041,000 people throughout the United States. Approximately 21,40028,400 of our employees are full time and the remaining approximately 10,00012,600 are part-time employees. Specialty hospitalOur specialty hospitals segment employees totaled approximately 21,500 and22,100, outpatient contract therapy and physical rehabilitation and occupational healthsegment employees totaled approximately 9,000.9,600 and Concentra segment employees totaled approximately 8,200. The remaining approximately 9001,100 employees were inperformed corporate management, administration and other support services primarily residing at our Mechanicsburg, Pennsylvania headquarters.

Competition

        We compete on the basis of the quality of the patient services we provide, the results that we achieve for our patients and the prices we charge for our services. The primary competitive factors in the specialty hospitalhospitals business include quality of services, charges for services and responsiveness to the needs of patients, families, payors and physicians. Other companies operate specialty hospitals that compete with our hospitals, including large operators of similar facilities, such as Kindred Healthcare Inc. and HealthSouth Corporation and rehabilitation units and stepdown units operated by acute care hospitals in the markets we serve. The competitive position of any hospital is also affected by the ability of its management to negotiate contracts with purchasers of group healthcare services, including private employers, managed care companies, preferred provider organizations and health maintenance organizations. Such organizations attempt to obtain discounts from established hospital charges. The importance of obtaining contracts with preferred provider organizations, health maintenance organizations and other organizations which finance healthcare, and its effect on a hospital's competitive position, vary from area to area, depending on the number and strength of such organizations.

        Our outpatient rehabilitation clinics face competition principally froma highly fragmented and competitive environment. The primary competitors that provide outpatient rehabilitation services include physician-owned physical therapy clinics, dedicated locally owned and managed outpatient rehabilitation clinics and hospital or university owned or affiliated ventures, as well as national and regional providers in the communities they serve and from selected national providers such asselect areas, including Athletico Physical Therapy, ATI Physical Therapy, Drayer Physical Therapy Institute, Physiotherapy Associates, and U.S. Physical Therapy in selected local areas.and Upstream Physical Therapy. Some of these competing clinics have longer operating histories and greater name recognition in these communities than our clinics, and they may have stronger relations with physicians in these communities on whom we rely for patient referrals. Because the barriers to entry are not substantial and current customers have the flexibility to move easily to new healthcare service providers, we believe that new outpatient physical therapy competitors can emerge relatively quickly.

        Our Concentra segment's occupational health services, consumer health and veteran's healthcare business face a highly fragmented and competitive environment. The primary competitors that provide occupational health services have typically been independent physicians, hospital emergency departments, and hospital-owned or hospital-affiliated medical facilities. Because the barriers to entry are not substantial and its current customers have the flexibility to move easily to new healthcare service providers, we believe that new competitors to Concentra can emerge relatively quickly. Furthermore, urgent care clinics in the local communities Concentra serves provide services similar to those Concentra offers, and, in some cases, competing facilities (1) are more established or newer than Concentra's, (2) may offer a broader array of services to patients than Concentra's and (3) may have larger or more specialized medical staffs to treat and serve patients. In the future, Concentra expects to encounter increased competition from hospital owned clinics, payor affiliated clinics, retail pharmacy-owned clinics, and healthcare companies.

Government Regulations

General

        The healthcare industry is required to comply with many complex laws and regulations at the federal, state and local government levels. These laws and regulations require that hospitals and facilities furnishing outpatient services (including outpatient rehabilitation clinics, meetConcentra medical centers, onsite clinics and CBOCs) comply with various requirements includingand standards. These laws and regulations include those relating to the adequacy of medical care, facilities and equipment, personnel, operating policies and procedures maintenance of adequate records, safeguarding protectedand recordkeeping as well as standards for reimbursement, fraud and abuse prevention and health information compliance with building codesprivacy and environmental protection and healthcare fraud and abuse.security. These laws and regulations are extremely complex, often overlap and, in many instances, the industry does not have the benefit of significant regulatory or judicial interpretation. If we fail to comply

Table of Contents

with applicable laws and regulations, we could suffer civil or criminal penalties, including the loss of our licenses to operate and our ability to participate in the Medicare, Medicaid and other federal and state healthcare programs.

Facility Licensure

        Our healthcare facilities are subject to state and local licensing statutes and regulations ranging from the adequacy of medical care to compliance with building codes and environmental protection laws. In order to assure continued compliance with these various regulations, governmental and other authorities periodically inspect our facilities, not onlyboth at scheduled intervals but alsoand in response to complaints from patients and others. While our facilities intend to comply with existing licensing and Medicare certification requirements and accreditation standards, there can be no assurance that regulatory authorities will determine that all applicable requirements are fully met at any given time. In addition, the state and local licensing laws are subject to changes or new interpretations that could impose additional burdens on our facilities. A determination by an applicable regulatory authority that a facility is not in compliance with these requirements could lead to the imposition of corrective action, assessment of fines and penalties, or loss of licensure, Medicare enrollment or certification or accreditation. These consequences could have an adverse effect on our company.

        Some states still require us to get approval under certificate of need regulations when we create, acquire or expand our facilities or services, or alter the ownership of such facilities, whether directly or indirectly. The certificate of need regulations vary from state to state, and are subject to change and new interpretation. If we fail to show public need and obtain approval in these states for our new facilities or changes to the ownership structure of existing facilities, we may be subject to civil or even criminal penalties, lose our facility license or become ineligible for reimbursement.

Professional Licensure, and Corporate Practice and Fee-Splitting Laws

        Healthcare professionals at our specialty hospitals and facilities furnishing outpatient rehabilitation clinicsservices are required to be individually licensed or certified under applicable state law. We take steps to ensure that our employees and agents possess all necessary licenses and certifications.

        Some states prohibit the "corporate practice of medicine" so thatmedicine," which restricts business corporations such as ours are restricted from practicing medicine through the direct employment of physicians and therapists.or from exercising control over medical decisions by physicians. Some states similarly prohibit the "corporate practice of therapy." The laws relating to corporate practice vary from state to state and are not fully developed in each state in which we have facilities. Typically, however, professional corporations owned and controlled by licensed professionals are exempt from corporate practice restrictions and may employ physicians or therapists to furnish professional services. Also, in some states hospitals are permitted to employ physicians.

        Some states also prohibit entities from engaging in certain financial arrangements, such as fee-splitting, with physicians or therapists. The laws relating to fee-splitting also vary from state to state and are not fully developed. Generally, these laws restrict business arrangements that involve a physician

Table of Contents

or therapist sharing medical fees with a referral source, but in some states these laws have been interpreted to extend to management agreements between physicians or therapists and business entities under some circumstances.

We believe that each of our facilities complies with any current corporate practice prohibitionand fee-splitting laws of the state in which it is located. For example,In states where we are prohibited by the corporate practice of medicine from directly employing licensed physicians, we typically enter into management agreements with professional corporations that are owned by licensed physicians, which, in turn, employ or contract with physicians who provide professional medical services in our facilities. Under those management agreements, we perform only non-medical administrative services, do not exercise control over the practice of medicine by the physicians, and structure compensation to avoid fee-splitting. In those states that apply the corporate practice of therapy prohibition, we either contract to obtain physician and therapisttherapy services from an entity permitted to employ themtherapists or we manage the medical orphysical therapy practice owned by licensed clinicianstherapists through which the clinicaltherapy services are provided. However, future

        Although we believe that our facilities comply with corporate practice and fee-splitting laws, if new regulations or judicial or administrative interpretations establish that our facilities do not comply with these laws, we could be subject to civil and perhaps criminal penalties. In addition, if any of our facilities is determined not to comply with corporate practice and fee-splitting laws, certain of our agreements relating to the facility may be determined to be unenforceable, including our management agreements with the professional corporations furnishing physician services or our payment arrangements with insurers or employers. Future interpretations of the corporate practice prohibition,and fee-splitting laws, the enactment of new legislation or the adoption of new regulations relating to these laws could cause us to have to restructure our business operations or close our facilities in a particular state. If new legislation, regulationsAny such penalties, determinations of unenforceability or interpretations establish that our facilities do not comply with state corporate practice prohibition, we could be subject to civil, and perhaps criminal, penalties. Any such restructuring or penalties could have a material adverse effect on our business.

Medicare Enrollment and Certification

        In order to participate in the Medicare program and receive Medicare reimbursement, each facility must comply with the applicable regulations of the United States Department of Health and Human Services relating to, among other things, the type of facility, its equipment, its personnel and its standards of medical care, as well as compliance with all applicable state and local laws and regulations. As of December 31, 2014,2015, 126 of the 129127 specialty hospitals we operated were certified as Medicare providers and three wereone was in the process of obtaining theirits certification. In addition, we provide the majority of our outpatient rehabilitation services through outpatient rehabilitation clinics certified by Medicare as rehabilitation agencies or "rehab agencies."

Table of Contents Our Concentra medical centers furnishing outpatient services are generally enrolled in Medicare as suppliers.

Accreditation

        Our specialty hospitals receive accreditation from The Joint Commission, the AOA, CARF and/or other healthcare accrediting organizations. As of December 31, 2014,2015, all of the 129127 specialty hospitals we operated were accredited by either The Joint Commission or the AOA. In addition, some of our IRFs have also applied for and received accreditation from CARF. Where required under our contracts with the Department of Veterans Affairs, our facilities furnishing outpatient services that operate as CBOCs are accredited by The Joint Commission or another healthcare accrediting organization. See "—Government Regulations—Veterans Affairs."

Workers' Compensation

        Workers' compensation is a state mandated, comprehensive insurance program that requires employers to fund or insure medical expenses, lost wages and other costs resulting from work related injuries and illnesses. Workers' compensation benefits and arrangements vary from state to state, and are

Table of Contents

often highly complex. In some states, payment for services covered by workers' compensation programs are subject to cost containment features, such as requirements that all workers' compensation injuries be treated through a managed care program, or the imposition of fee schedules or payment caps for services furnished to injured employees. Some state workers' compensation laws limit the ability of an employer to select the providers furnishing care to injured employees. Several states require that physicians furnishing non-emergency services to workers' compensation patients must register with the applicable state agency and undergo special continuing education and training. Workers' compensation programs may also impose other requirements that affect the operations of our facilities furnishing outpatient services. Net operating revenues generated directly from workers' compensation programs represented approximately 17% of our net operating revenue from outpatient rehabilitation services, 1% of our net operating revenue from our specialty hospitals and 52% of our net operating revenue from our Concentra segment for the year ended December 31, 2015.

        Our facilities furnishing outpatient services are reimbursed for services furnished to injured workers by payors pursuant to the applicable state workers' compensation statutes. Most of the states in which we maintain operations reimburse providers for services payable under workers' compensation laws pursuant to a treatment-specific fee schedule with established maximum reimbursement levels. In states without such fee schedules, healthcare providers are often reimbursed based on "usual and customary" fees benchmarked by market data and negotiated by providers with payors and networks.

        Inadequate increases to the applicable fee schedule amounts for our services, and changes in state workers' compensation laws, including cost containment initiatives, could have a negative impact on the operations and financial performance of those facilities.

Veterans Affairs

        The Veterans Affairs health system is the largest integrated healthcare system in the U.S. and includes over 150 hospitals, 800 CBOCs (of which only 166 are operated by contractors) and 260 veterans medical centers. As of December 31, 2015, we had 33 CBOCs, which were established to provide services to veterans residing in catchment areas under agreements with the Department of Veterans Affairs. The awarding of such agreements is regulated by laws related to federal government procurements generally, including the Federal Acquisition Regulations. Our contracts with the Department of Veterans Affairs include administrative and clinical services, performance standards, qualifications and other contractor requirements and information and security requirements. In general, our facilities furnishing outpatient services that are CBOCs provide outpatient primary care in exchange for a capitated monthly fee based on the number of eligible patients then enrolled in that CBOC.

Overview of U.S. and State Government Reimbursements

Medicare Program in General

        The Medicare program reimburses healthcare providers for services furnished to Medicare beneficiaries, which are generally persons age 65 and older, those who are chronically disabled, and those suffering from end stage renal disease. The program is governed by the Social Security Act of 1965 and is administered primarily by the Department of Health and Human Services and CMS. Net operating revenues generated directly from the Medicare program represented approximately 47% of our consolidated net operating revenues for the year ended December 31, 2012, 46% for the year ended December 31, 2013, and 45% for the year ended December 31, 2014.2014 and 37% for the year ended December 31, 2015.

        The Medicare program reimburses various types of providers, including LTCHs, IRFs and outpatient rehabilitation providers, using different payment methodologies. The Medicare reimbursement systems specific to LTCHs, IRFs and outpatient rehabilitation providers, as described below, are different than the system applicable to general acute care hospitals. If any of our hospitals fail to comply with requirements

Table of Contents

for payment under Medicare reimbursement systems for LTCHs or IRFs, as applicable, that hospital will be paid under the system applicable to general acute care hospitals. For general acute care hospitals, Medicare payments for inpatient care are made under the inpatient prospective payment system, or "IPPS," under which a hospital receives a fixed payment amount per discharge (adjusted for area wage differences) using Medicare severity diagnosis-related groups, or "MS-DRGs." The general acute care hospital MS-DRG payment rate is based upon the national average cost of treating a Medicare patient's condition, based on severity levels of illness, in that type of facility. Although the average length of stay varies for each MS-DRG, the average stay of all Medicare patients in a general acute care hospital is substantially less than the average length of stay in LTCHs and IRFs. Thus, the prospective payment system for general acute care hospitals creates an economic incentive for those hospitals to discharge medically complex Medicare patients to a post-acute care setting as soon as clinically possible. Effective October 1, 2005, CMS expanded its post-acute care transfer policy under which general acute care hospitals are paid on a per diem basis rather than the full MS-DRG rate if a patient is discharged early to certain post-acute care settings, including LTCHs and IRFs. When a patient is discharged from selected MS-DRGs to, among other providers, an LTCH or IRF, the general acute care hospital may be reimbursed below the full MS-DRG payment if the patient's length of stay is less than the geometric mean length of stay for the MS-DRG.

        The Medicare Access and CHIP Reauthorization Act of 2015, enacted on April 16, 2015, reforms Medicare payment policy for services paid under the Medicare physician fee schedule, including our outpatient rehabilitation services. The law repeals the sustainable growth rate (the "SGR") formula effective January 1, 2015, and establishes a new payment framework consisting of specified updates to the Medicare physician fee schedule, a new Merit-Based Incentive Payment System ("MIPS"), and incentives for participation in alternative payment models ("APMs"). To finance these provisions, the Medicare Access and CHIP Reauthorization Act of 2015 reduces market basket updates for post-acute care providers, including LTCHs and IRFs, among other Medicare payment cuts. As noted below, the law sets the annual prospective payment system update for fiscal year 2018 at 1% for LTCHs and IRFs, as well as skilled nursing facilities, home health agencies, and hospices. The law also extends the exceptions process for outpatient therapy caps through December 31, 2017.

Long Term Acute Care Hospital Medicare Reimbursement

        The Medicare payment system for LTCHs is based on a prospective payment system specifically applicable to LTCHs. The long term care hospital prospective payment system, or "LTCH-PPS," was established by CMS final regulations published on August 30, 2002, and applies to LTCHs for cost reporting periods beginning on or after October 1, 2002. The policies and payment rates under LTCH-PPS are subject to annual updates and revisions. Under LTCH-PPS, each patient discharged from an LTCH is assigned to a distinct "MS-LTC-DRG," which is a Medicare severity diagnosis-related group for LTCHs, and an LTCH is generally paid a pre-determined fixed amount applicable to the assigned MS-LTC-DRG (adjusted for area wage differences), subject to exceptions for short stay and high cost outlier patients (described below). CMS assigns relative weights to each MS-LTC-DRG to reflect their relative use of medical care resources. The payment amount for each MS-LTC-DRG is intended to reflect the average cost of treating a Medicare patient assigned to that MS-LTC-DRG in an LTCH.

Table of Contents

Standard Federal Rate

        Payment under the LTCH-PPS is dependent on determining the patient classification, that is, the assignment of the case to a particular MS-LTC-DRG, the weight of the MS-LTC-DRG and the standard federal payment rate. There is a single standard federal rate that encompasses both the inpatient operating costs, which includes a labor and non-labor component, and capital-related costs that CMS updates on an annual basis. LTCH-PPS also includes special payment policies that adjust the payments for some patients

Table of Contents

based on the patient's length of stay, the facility's costs, whether the patient was discharged and readmitted and other factors.

Patient Criteria

        The BBA of 2013, enacted December 26, 2013, establishes new payment limits for Medicare patients discharged from an LTCH who do not meet specified criteria. Specifically, for Medicare patients discharged in cost reporting periods beginning on or after October 1, 2015, LTCHs will be reimbursed under LTCH-PPS only if, immediately preceding the patient's LTCH admission, the patient was discharged from a general acute care hospital paid under IPPS and the patient's stay included at least three days in an intensive care unit (ICU) or coronary care unit (CCU) or the patient is assigned to an MS-LTC-DRG for cases receiving at least 96 hours of ventilator services in the LTCH. In addition, to be paid under LTCH-PPS the patient's discharge from the LTCH may not include a principal diagnosis relating to psychiatric or rehabilitation services. For any Medicare patient who does not meet the new criteria, the LTCH will be paid a lower "site-neutral" payment rate, which will be the lower of (1) the IPPS comparable per-diem payment rate capped at the MS-DRG including any outlier payments, or (2) 100 percent of the estimated costs for services.

        The BBA of 2013 provides for a transition to the site-neutral payment rate for those patients not paid under LTCH-PPS. During the transition period (cost reporting periods beginning on or after October 1, 2015 through September 30, 2017), a blended rate will be paid for Medicare patients not meeting the new criteria. The blended rate will comprise half the site-neutral payment rate and half the LTCH-PPS payment rate. For discharges in cost reporting periods beginning on or after October 1, 2017, only the site-neutral payment rate will apply for Medicare patients not meeting the new criteria.

        In addition, for cost reporting periods beginning on or after October 1, 2019, qualifying discharges from an LTCH will continue to be paid at the LTCH-PPS payment rate, unless the number of discharges for which payment is made under the site-neutral payment rate is greater than 50% of the total number of discharges from the LTCH. If the number of discharges for which payment is made under the site-neutral payment rate is greater than 50%, then beginning in the next cost reporting period all discharges from the LTCH will be reimbursed at the site-neutral payment rate. The BBA of 2013 requires CMS to establish a process for an LTCH subject to the site-neutral payment rate to re-qualify for payment under LTCH-PPS.

        Payment adjustments, including the interrupted stay policy and the 25 Percent Rule (discussed below), apply to LTCH discharges regardless of whether the case is paid at the LTCH-PPS payment rate or the site-neutral payment rate. However, short stay outlier payment adjustments do not apply to cases paid at the site-neutral payment rate. Beginning with fiscal year 2016, CMS will calculate the annual recalibration of the MS-LTC-DRG relative payment weighting factors using only data from LTCH discharges that meet the criteria for exclusion from the site-neutral payment rate. In addition, beginning in fiscal year 2016, CMS will apply the IPPS fixed-loss amount to site-neutral cases, rather than the LTCH PPS fixed-loss amount. For fiscal year 2016, the IPPS fixed-loss amount is set at $22,544 and the LTCH-PPS fixed-loss amount is estimated to be $16,423. CMS will calculate the LTCH-PPS fixed-loss amount using only data from cases paid at the LTCH-PPS payment rate, excluding cases paid at the site-neutral rate.

        Each of our LTCHs has their own unique annual cost reporting period. As a result, the new payment limits will become effective for each of our LTCHs at different points in time over a twelve month period beginning on October 1, 2015. As of December 31, 2015, 16 of our LTCHs have cost reporting periods that began during the fourth quarter of 2015 and 37, 19 and 36 of our LTCHs have cost reporting periods commencing during the first quarter, second quarter and third quarters of 2016, respectively.

Table of Contents

Short Stay Outlier Policy

        CMS established a different payment methodology for Medicare patients with a length of stay less than or equal to five-sixths of the geometric average length of stay for that particular MS-LTC-DRG, referred to as a short stay outlier, or "SSO." SSO cases are paid based on the lesser of (1) 100% of the average cost of the case, (2) 120% of the MS-LTC-DRG specific per diem amount multiplied by the patient's length of stay, (3) the full MS-LTC-DRG payment, or (4) a per diem rate derived from blending 120% of the MS-LTC-DRG specific per diem amount with a per diem rate based on the general acute care hospital IPPS.

        The SSO rule also has a category referred to as a "very short stay outlier",outlier," which applies to cases with a length of stay that is less than the average length of stay plus one standard deviation for the same MS-DRG under IPPS, referred to as the so-called "IPPS comparable threshold." The LTCH payment for very short stay outlier cases is equivalent to the general acute care hospital IPPS per diem rate. The Medicare, Medicaid, and SCHIP Extension Act of 2007, or the "SCHIP Extension Act," as amended by

Table of Contents

the American Recovery and Reinvestment Act, or the "ARRA," and the Patient Protection and Affordable Care Act, or the "ACA," prevented CMS from applying the very short stay outlier policy during the period from December 29, 2007 through December 28, 2012. The very short stay outlier policy again became applicable to discharges occurring on or after December 29, 2012.

High Cost Outliers

        Some cases are extraordinarily costly, producing losses that may be too large for hospitals to offset. Cases with unusually high costs, referred to as "high cost outliers," receive a payment adjustment to reflect the additional resources utilized. CMS provides an additional payment if the estimated costs for the patient exceed the adjusted MS-LTC-DRG payment plus a fixed-loss amount that is established in the annual payment rate update.

Interrupted stays

        An interrupted stay is defined as a case in which an LTCH patient, upon discharge, is admitted to a general acute care hospital, IRF or skilled nursing facility/swing-bed and then returns to the same LTCH within a specified period of time. If the length of stay at the receiving provider is equal to or less than the applicable fixed period of time, it is considered to be an interrupted stay case and the case is treated as a single discharge for the purposes of payment to the LTCH.

Freestanding, HIH and Satellite LTCHs

        LTCHs may be organized and operated as freestanding facilities or as HIHs. As its name suggests, a freestanding LTCH is not located on the campus of another hospital. For such purpose, "campus" means the physical area immediately adjacent to a hospital's main buildings, other areas and structures that are not strictly contiguous to a hospital's main buildings but are located within 250 yards of its main buildings, and any other areas determined, on an individual case basis by the applicable CMS regional office, to be part of a hospital's campus. Conversely, an HIH is an LTCH that is located on the campus of another hospital. An LTCH, whether freestanding or an HIH, that uses the same Medicare provider number of an affiliated "primary site" LTCH is known as a "satellite." Under Medicare policy, a satellite LTCH must be located within 35 miles of its primary site LTCH and be administered by such primary site LTCH. A primary site LTCH may have more than one satellite LTCH. CMS sometimes refers to a satellite LTCH that is freestanding as a "remote location."

Facility Certification Criteria

        The LTCH-PPS regulations define the criteria that must be met in order for a hospital to be certified as an LTCH. To be eligible for payment under the LTCH-PPS, a hospital must be primarily engaged in

Table of Contents

providing inpatient services to Medicare beneficiaries with medically complex conditions that require a long hospital stay. In addition, by definition, LTCHs must meet certain facility criteria, including (1) instituting a review process that screens patients for appropriateness of an admission and validates the patient criteria within 48 hours of each patient's admission, evaluates regularly their patients for continuation of care and assesses the available discharge options, (2) having active physician involvement with patient care that includes a physician available on-site daily and additional consulting physicians on call, and (3) having an interdisciplinary team of healthcare professionals to prepare and carry out an individualized treatment plan for each patient.

        An LTCH must have an average inpatient length of stay for Medicare patients (including both Medicare covered and non-covered days and Medicare Advantage Days) of greater than 25 days. LTCHs that fail to exceed an average length of stay of 25 days during any cost reporting period may be paid under the general acute care hospital IPPS if not corrected within established timeframes. CMS, through its contractors, determines whether an LTCH has maintained an average length of stay of greater than 25 days during each annual cost reporting period. Under the BBA of 2013, for discharges occurring in cost reporting periods beginning on or after October 1, 2015, LTCH cases paid at the site-neutral rate and Medicare Advantage cases are excluded from the LTCH average length of stay calculation.

Table of Contents

        Prior to qualifying under the payment system applicable to LTCHs, a new LTCH initially receives payments under the general acute care hospital IPPS. The LTCH must continue to be paid under this system for a minimum of six months while meeting certain Medicare LTCH requirements, the most significant requirement being an average length of stay for Medicare patients (including both Medicare covered and non-covered days) greater than 25 days.

25 Percent Rule

        The "25 Percent Rule" is a downward payment adjustment that applies if the percentage of Medicare patients discharged from LTCHs who were admitted from a referring hospital (regardless of whether the LTCH or LTCH satellite is co-located with the referring hospital) exceeds the applicable percentage admissions threshold during a particular cost reporting period. Specifically, the payment rate for Medicare patients above the percentage admissions threshold are subject to a downward payment adjustment. For Medicare patients above the applicable percentage admissions threshold, the LTCH is reimbursed at a rate comparable to that under general acute care hospital IPPS, which is generally lower than LTCH-PPS rates. Cases that reach outlier status in the referring hospital do not count toward the admissions threshold and are paid under LTCH-PPS.

        The SCHIP Extension Act, as amended by the ARRA and the ACA, has limited the full application of the 25 Percent Rule. However, the SCHIP Extension Act did not postpone the application of the percentage admissions threshold to those Medicare patients discharged from an LTCH HIH or satellite that were admitted from a non-co-located hospital. In addition, CMS adopted regulations providing for a one-year extension of relief from the full application of the 25 Percent Rule. As a result, full implementation of the Medicare percentage admissions thresholds did not go into effect until cost reporting periods beginning on or after October 1, 2013, except for certain LTCHs with cost reporting periods that begin between July 1, 2012 and through September 30, 2012. Specifically, those freestanding facilities, grandfathered HIHs and grandfathered satellites with cost reporting periods beginning on or after July 1, 2012 and through September 30, 2012 were subject to a modified 25 Percent Rule for discharges occurring in a three month period between July 1, 2012 and September 30, 2012.

Table of Contents

        The BBA of 2013 further delays, and in some cases permanently suspends, the application of the 25 Percent Rule. The following table describes the types of LTCHs and the statutory and regulatory relief they have received from the payment adjustment for these discharges:

Table of Contents

Table of Contents

        After the expiration of the regulatory relief, as described above, our LTCHs (whether freestanding, HIH or satellite) will be subject to a downward payment adjustment for any Medicare patients who were admitted from a co-located or a non-co-located hospital and that exceed the applicable percentage admissions threshold of all Medicare patients discharged from the LTCH during the cost reporting period. These regulatory changes will have an adverse financial impact on the net operating revenues and profitability of many of these hospitals for cost reporting periods beginning on or after July 1, 2016.

        The BBA of 2013 requires CMS to report to Congress before October 2016 on the need for any further extensions or modifications of the extensions of the 25 Percent Rule. In addition, the BBA of 2013 requires the Medicare Payment Advisory Commission, or "MedPAC," to report to Congress by June 2019 on the need to continue applying the 25 Percent Rule, the effect of site-neutral payment on LTCHs, and recommendations on how to change the site-neutral payment policy.

Moratorium on New LTCHs, LTCH Satellite Facilities and LTCH beds

        The SCHIP Extension Act imposed a moratorium on the establishment and classification of new LTCHs, LTCH satellite facilities and LTCH beds in existing LTCHs or satellite facilities. The ACA extended this moratorium by two years. The moratorium expired on December 28, 2012. The BBA of 2013 reinstated the moratorium on the establishment and classification of new LTCHs or LTCH satellite facilities, and on the increase of LTCH beds in existing LTCHs or satellite facilities beginning January 1, 2015 through September 30, 2017. The PAMA advanced the commencement date of the reinstated moratorium from January 1, 2015 to April 1, 2014. The PAMA includes exceptions to the moratorium that are applicable to the establishment and classification of new LTCHs or LTCH satellites facilities currently under development. The new moratorium will not apply to LTCHs or LTCH satellites facilities that: (1) began their qualifying period to become an LTCH on or before April 1, 2014; (2) had a binding written agreement as of April 1, 2014 with an unrelated party for construction, renovation, or lease for an LTCH and have expended, before April 1, 2014, at least 10% of the estimated cost of the project (or, if less, $2,500,000); or (3) had obtained a certificate of need on or before April 1, 2014. The moratorium as reinstated on April 1, 2014 provides no exceptions for increases in the number of certified beds in existing LTCHs and LTCH satellites. Further, any LTCH that establishes a new satellite, based upon meeting the criteria for an exception to the moratorium, must reduce beds elsewhere in the LTCH in order to have beds in the new satellite location.

One-Time Budget Neutrality Adjustment

        Congress required that the LTCH-PPS payment rates maintain budget neutrality during the first years of the prospective payment system with total expenditures that would have been made under the previous reasonable cost-based payment system. The LTCH-PPS regulations give CMS the ability to make a one-time adjustment to the standard federal rate to correct any "significant difference between actual payments and estimated payments for the first year" of LTCH-PPS. The SCHIP Extension Act precluded CMS from implementing the one-time prospective adjustment to the LTCH standard federal rate for a period of three years. The ACA extended the stay on CMS's ability to adopt a one-time budget neutrality adjustment to LTCH-PPS through December 28, 2012. In the update to the Medicare policies and payment rates for fiscal year 2013, CMS adopted a one-time budget neutrality adjustment that results in a permanent negative adjustment of 3.75% to the LTCH base rate. CMS is implementing the adjustment over a three-year period by applying a factor of 0.98734 to the standard federal rate in fiscal years 2013, 2014 and 2015, except that the adjustment woulddid not apply to payments for discharges occurring on or after October 1, 2012 through December 28, 2012.

Annual Payment Rate Update

Fiscal Year 2013.    On August 1, 2012, CMS published the final rule updating the policies and payment rates for LTCH-PPS for fiscal year 2013 (affecting discharges and cost reporting periods beginning on or after October 1, 2012 through September 30, 2013). Two different standard federal rates apply during fiscal year 2013. The standard federal rate for discharges on or after October 1, 2012 and before December 29, 2012 is $40,916 and the standard federal rate for discharges on or after December 29, 2012 for the remainder of fiscal year 2013 is $40,398, both of which are an increase from the fiscal year 2012 standard federal rate of $40,222. The update to the standard federal rate for fiscal year 2013 through December 28, 2012 included a market basket increase of 2.6%, less a productivity adjustment of 0.7%, and less an additional reduction of 0.1% mandated by the ACA. The standard federal rate for the period of December 29, 2012 through the remainder of fiscal 2013 is further reduced by a portion of the one-time budget neutrality adjustment of 1.266%, as discussed above. The final rule establishes a fixed-loss amount for high cost outlier cases for fiscal year 2013 of $15,408, which is a decrease from the fixed-loss amount in the 2012 fiscal year of $17,931.

The fixed-loss amount for high cost outlier cases iswas set at $14,972, which iswas an increase from the fixed-loss amount in the 2014 fiscal year of $13,314.

Fiscal Year 2016.    On August 17, 2015, CMS published the final rule updating policies and payment rates for the LTCH-PPS for fiscal year 2016 (affecting discharges and cost reporting periods beginning on or after October 1, 2015 through September 30, 2016). The standard federal rate is set at $41,763, an increase from the standard federal rate applicable during fiscal year 2015 of $41,044. The update to the standard federal rate for fiscal year 2016 includes a market basket increase of 2.4%, less a productivity adjustment of 0.5%, and less a reduction of 0.2% mandated by the ACA. The fixed-loss amount for high cost outlier cases paid under LTCH-PPS is set at $16,423, which is an increase from the fixed-loss amount in the 2015 fiscal year of $14,972. The fixed-loss amount for high cost outlier cases paid under the site-neutral payment rate described below is set at $22,544.

Medicare Market Basket Adjustments

        The ACA instituted a market basket payment adjustment to LTCHs. In fiscal years 2015 and 2016 the market basket update will be reduced by 0.2%. In fiscal years 2017 through 2019, the market basket update will be reduced by 0.75%. The Medicare Access and CHIP Reauthorization Act of 2015 sets the annual update for fiscal year 2018 at 1% after taking into account the market basket payment reduction of 0.75% mandated by the ACA. The ACA specifically allows these market basket reductions to result in less than a 0% payment update and payment rates that are less than the prior year.

Medicare Reimbursement of Inpatient Rehabilitation Facility Services

        IRFs are paid under a prospective payment system specifically applicable to this provider type, which is referred to as "IRF-PPS." Under the IRF-PPS, each patient discharged from an IRF is assigned to a case mix group, or "IRF-CMG," containing patients with similar clinical conditions that are expected to require similar amounts of resources. An IRF is generally paid a pre-determined fixed amount applicable to the assigned IRF-CMG (subject to applicable case adjustments related to length of stay and facility level adjustments for location and low income patients). The payment amount for each IRF-CMG is intended to reflect the average cost of treating a Medicare patient's condition in an IRF relative to patients with conditions described by other IRF-CMGs. The IRF-PPS also includes special payment policies that adjust the payments for some patients based on the patient's length of stay, the facility's costs, whether the patient was discharged and readmitted and other factors.

Facility Certification Criteria

        Our rehabilitation hospitals must meet certain facility criteria to be classified as an IRF by the Medicare program, including: (1) a provider agreement to participate as a hospital in Medicare, (2) a

Table of Contents

preadmission screening procedure, (3) ensuring that patients receive close medical supervision and furnish, through the use of qualified personnel, rehabilitation nursing, physical therapy, and occupational therapy, plus, as needed, speech therapy, social or psychological services, and orthotic and prosthetic services, (4) a full-time, qualified director of rehabilitation, (5) a plan of treatment for each inpatient that is established, reviewed, and revised as needed by a physician in consultation with other professional personnel who provide services to the patient, and (6) a coordinated multidisciplinary team approach in the rehabilitation of each inpatient, as documented by periodic clinical entries made in the patient's medical record to note the patient's status in relationship to goal attainment, and that team conferences are held at least every two weeks to determine the appropriateness of treatment. Failure to comply with any of the classification criteria may result in the denial of claims for payment or cause a hospital to lose its status as an IRF and be paid under the prospective payment system that applies to general acute care hospitals.

Patient Classification Criteria

        Under the IRF certification criteria that has been in effect since 1983, in order to qualify as an IRF, a hospital was required to satisfy certain operational criteria as well as demonstrate that, during its most recent 12-month cost reporting period, it served an inpatient population of whom at least 75% required intensive rehabilitation services for one or more of 10 conditions specified in the regulation. We refer to such 75% requirement as the "75% Rule."

        New IRF certification criteria became effective for cost reporting periods beginning on or after July 1, 2004 as a result of the major changes that CMS adopted on May 7, 2004 to the 75% Rule that: (1) temporarily lowered the 75% compliance threshold (starting at 50% and phasing to 75% over four years), (2) modified and expanded from 10 to 13 the medical conditions used to determine whether a hospital qualifies as an IRF, (3) identified the conditions under which comorbidities can be used to verify compliance with the 75% Rule, and (4) changed the timeframe used to determine compliance with the 75% Rule from "the most recent 12-month cost reporting period" to "the most recent, consecutive, and appropriate 12-month period," with the result that a determination of non-compliance with the applicable compliance threshold will affect the facility's certification as an IRF for its cost reporting period that begins immediately after the 12-month review period.

        Under the Deficit Reduction Act of 2005 (the "DRA"), enacted on February 8, 2006, Congress extended the phase-in period for the 75% Rule by maintaining the compliance threshold at 60% (rather than increasing it to the scheduled 65%) during the 12-month period beginning on July 1, 2006. The compliance threshold was then to increase to 65% for cost reporting periods beginning on or after July 1, 2007 and again to 75% for cost reporting periods beginning on or after July 1, 2008. However, the SCHIP Extension Act included a permanent freeze in the 75% Rule patient classification criteria compliance threshold at 60% (with comorbidities counting toward this threshold), at which time the requirement became known as the "60% Rule."

        Compliance with the patient classification criteria is demonstrated through either medical review or the "presumptive" method, in which a patient's diagnosis codes are compared to a "presumptive compliance" list. CMS has announced that it will remove a number of diagnosis codes from the presumptive compliance list. According to CMS, these conditions do not demonstrate the need for intensive inpatient rehabilitation services in the absence of additional facts that would have to be pulled from a patient's medical record. As a result, beginning on or afterEffective October 1, 2015, CMS removed a number of diagnosis codes previously onfrom the presumptive compliance list will be removed, including diagnosis codes in the following categories: non-specificnonspecific diagnosis codes, arthritis diagnosis codes, unilateral upper extremity amputations diagnosis codes, amputation status codes, prosthetic fitting and adjustment codes, some congenital anomalies diagnosis codes and other miscellaneous diagnosis codes.

Annual Payment Rate Update

Fiscal Year 2013.    On July 30, 2012, CMS published the final rule updating policies and payment rates for IRF-PPS for fiscal year 2013 (affecting discharges and cost reporting periods beginning on or after October 1, 2012 through September 30, 2013). The standard payment conversion factor for discharges during fiscal year 2013 is $14,343, which is an increase from the fiscal year 2012 standard payment conversion factor of $14,076. The update to the standard payment conversion factor for fiscal year 2013 includes a market basket increase of 2.7%, less a productivity adjustment of 0.7%, less an additional reduction of 0.1% mandated by the ACA. CMS decreased the outlier threshold amount for fiscal year 2013 to $10,466 from $10,713 established in the final rule for fiscal year 2012.

        Fiscal Year 2014.    On August 6, 2013, CMS published the final rule updating policies and payment rates for IRF-PPS for fiscal year 2014 (affecting discharges and cost reporting periods beginning on or after October 1, 2013 through September 30, 2014). The standard payment conversion factor for discharges for fiscal year 2014 iswas $14,846, which iswas an increase from the fiscal year 2013 standard payment conversion factor of $14,343.

        Fiscal Year 2015.2015.    On August 6, 2014, CMS published the final rule updating policies and payment rates for IRF-PPS for fiscal year 2015 (affecting discharges and cost reporting periods beginning on or after October 1, 2014 through September 30, 2015). The standard payment conversion factor for discharges for fiscal year 2015 iswas $15,198, which iswas an increase from the fiscal year 2014 standard payment conversion factor of $14,846. The update to the standard payment conversion factor for fiscal year 2015 includes a market basket increase of 2.9%, less a productivity adjustment of 0.5%, and less an additionala reduction of 0.2% mandated by the ACA. CMS decreased the outlier threshold amount for fiscal year 2015 to $8,848 from $9,272 established in the final rule for fiscal year 2014.

Fiscal Year 2016.    On August 6, 2015, CMS published the final rule updating policies and payment rates for IRF-PPS for fiscal year 2016 (affecting discharges and cost reporting periods beginning on or after October 1, 2015 through September 30, 2016). The standard payment conversion factor for discharges for fiscal year 2016 is set at $15,478, which is an increase from the fiscal year 2015 standard payment conversion factor of $15,198. The update to the standard payment conversion factor for fiscal year 2016 includes a market basket increase of 2.4%, less a productivity adjustment of 0.5%, and less a reduction of 0.2% mandated by the ACA. CMS decreased the outlier threshold amount for fiscal year 2016 to $8,658 from $8,848 established in the final rule for fiscal year 2015.

Medicare Market Basket Adjustments

        The ACA instituted a market basket payment adjustment for IRFs. In fiscal years 2015 and 2016, the market basket update will be reduced by 0.2%. In fiscal years 2017 through 2019, the market basket update will be reduced by 0.75%. The Medicare Access and CHIP Reauthorization Act of 2015 sets the annual update for fiscal year 2018 at 1% after taking into account the market basket payment reduction of 0.75% mandated by the ACA. The ACA specifically allows these market basket reductions to result in less than a 0% payment update and payment rates that are less than the prior year.

Medicare Reimbursement of Outpatient Rehabilitation Services

        The Medicare program reimburses outpatient rehabilitation providers based on the Medicare physician fee schedule. TheHistorically, the Medicare physician fee schedule rates are automaticallyhave updated annually based on a formula, called the sustainable growth rate, or "SGR," formula, contained in legislation.SGR formula. The SGR formula has resulted in automatic reductions in rates every year since 2002; however, for each year through March 31, 2015 CMS or Congress has taken action to prevent the SGR formula reductions. CMS estimatedThe Medicare Access and CHIP Reauthorization Act of 2015 repeals the SGR formula effective for services provided on November 13, 2014 that beginning Aprilor after January 1, 2015, and establishes a new payment framework consisting of specified updates to the Medicare physician fee schedule, a new MIPS, and APMs. For services provided between January 1, 2015 and June 30, 2015, a 0% payment update was applied to the Medicare physician fee schedule payment rates would be reduced by 21.2% as a result of the SGR formula. The PAMA temporarily blocks the payment reduction caused by the SGR formula through Marchrates. For services provided between July 1, 2015 and December 31, 2015, and replaces it with a 0.5% update was applied to the fee schedule payment increase forrates. For services provided in 2016 through December 31, 2014 and2019, a 0% payment0.5% update from January 1, 2015 through March 31, 2015.

For services provided in 2020 through 2025, a 0.0% percent update will commencebe applied each year to the fee schedule payment rates, subject to MIPS and APM adjustments. Finally, in 2026 and subsequent years eligible professionals participating in APMs that meet

certain criteria would receive annual updates of 0.75%, while all other professionals would receive annual updates of 0.25%.

        The Medicare Access and CHIP Reauthorization Act of 2015 requires that payments under the fee schedule be adjusted starting in 2019 based on April 1, 2015, unless Congress again takes legislative actionperformance in MIPS, which will consolidate the three existing incentive programs focused on quality, resource use, and meaningful use of electronic health records. The law requires the Secretary of Health and Human Services to preventestablish the SGR formula reductionsMIPS requirements under which a provider's performance is assessed according to established performance standards and used to determine an adjustment factor that is then applied to the professional's payment for a year. Each year from going into effect.2019-2024 professionals who receive a significant share of their revenues through an APM (such as accountable care organizations or bundled payment arrangements) that involves risk of financial losses and a quality measurement component will receive a 5% bonus. The bonus payment for APM participation is intended to encourage participation and testing of new APMs and promotes the alignment of incentives across payors. The specifics of the MIPS and APM adjustments beginning in 2019 and 2020, respectively, will be subject to future notice and comment rule-making. For the year ended December 31, 2014,2015, we received approximately 10%11% of our outpatient rehabilitation net operating revenues from Medicare.

        In addition, MedPAC recommended that Congress direct CMS to collect data on provider service volume and work time to establish more accurate relative value unit payment rates and to identify and reduce overpriced fee schedule services. Similarly, the ACA requires CMS to identify and review potentially misvalued codes and make appropriate adjustments to the relative values of those services identified as being misvalued.

Therapy Caps

        Beginning on January 1, 1999, the Balanced Budget Act of 1997 subjected certain outpatient therapy providers reimbursed under the Medicare physician fee schedule to annual limits for therapy expenses. Effective January 1, 2015,2016, the annual limit on outpatient therapy services is $1,940$1,960 for combined physical and speech language pathology services and $1,940$1,960 for occupational therapy services. The per beneficiary caps were $1,920$1,940 for calendar year 2014.2015.

        The annual limits for therapy expenses historically did not apply to services furnished and billed by outpatient hospital departments. However, the PAMA,Medicare Access and CHIP Reauthorization Act of 2015, and prior legislation, extended the annual limits on therapy expenses and the manual medical review thresholds to services furnished in hospital outpatient department settings through MarchDecember 31, 2015.2017. The application of annual limits to hospital outpatient department settings will sunset on MarchDecember 31, 20152017 unless Congress extends it. We operated 1,023

Table of Contents

1,038 outpatient rehabilitation clinics at December 31, 2014,2015, of which 164169 are provider based outpatient rehabilitation clinics operated as departments of the inpatient rehabilitation hospitals we operated.

        In the DRA, Congress implemented an exceptions process to the annual limit for therapy expenses. Under this process, a Medicare enrollee (or person acting on behalf of the Medicare enrollee) is able to request an exception from the therapy caps if the provision of therapy services was deemed to be medically necessary. Therapy cap exceptions have been available automatically for certain conditions and on a case by case basis upon submission of documentation of medical necessity. The PAMAMedicare Access and CHIP Reauthorization Act of 2015 extends the exceptions process for outpatient therapy caps through MarchDecember 31, 2015.2017. Unless Congress extends the exceptions process, the therapy caps will apply to all outpatient therapy services beginning AprilJanuary 1, 2015,2018, except those services furnished and billed by outpatient hospital departments.

        The Middle Class Tax Relief and Job Creation Act of 2012 made several changes to the exceptions process to the annual limit for therapy expenses. For any claim above the annual limit, the claim must contain a modifier indicating that the services are medically necessary and justified by appropriate documentation in the medical record. In addition, all therapy claims, whether above or below the annual limit, must include the national provider identifier (NPI) of the physician responsible for certifying and periodically reviewing the plan of care. Effective October 1, 2012, all claims exceeding $3,700 are subject to a manual medical review process. The $3,700 threshold is applied separately to the combined physical therapy/speech therapy cap and the occupational therapy cap. The PAMA extends through March 31,Medicare Access and CHIP Reauthorization Act of 2015 requires the requirement that Medicare performSecretary of Health and Human Services to replace the manual medical review process with a new medical review process using such factors as the Secretary may determine to be

The law specifies that such factors may include: (a) whether the therapy provider has a high claims denial percentage for therapy services when anor is less compliant with applicable requirements; (b) whether the therapy provider has a pattern of billing for therapy services that is aberrant or questionable compared with peers, or otherwise has questionable billing practices, such as billing medically unlikely units of services in a day; (c) whether the therapy provider is newly enrolled or has not previously furnished therapy under Medicare; (d) the types of medical conditions treated by the services; and (e) whether the therapy provider is part of a group.

Multiple Procedure Payment Reduction

        CMS adopted MPPR Reduction for therapy services in the final update to the Medicare physician fee schedule for calendar year 2011. This MPPR Reduction policy became effective January 1, 2011 and applies to all outpatient therapy services paid under Medicare Part B. The MPPR Reduction policy applies across all therapy disciplines — disciplines—occupational therapy, physical therapy and speech-language pathology. Under the policy, the Medicare program pays 100% of the practice expense component of the therapy procedure or unit of service with the highest Relative Value Unit, and then reduces the payment for the practice expense component for the second and subsequent therapy procedures or units of service furnished during the same day for the same patient, regardless of whether those therapy services are furnished in separate sessions. In 2011 and 2012, the second and subsequent therapy service furnished during the same day for the same patient was reduced by 20% in office and other non-institutional settings and by 25% in institutional settings. The American Taxpayer Relief Act of 2012 increased the payment reduction in either setting to 50% effective April 1, 2013 for all outpatient therapy services. Our outpatient rehabilitation therapy services are primarily offered in institutional settings and, as such, were subject to the applicable 25% payment reduction in the practice expense component for the second and subsequent therapy services furnished by us to the same patient on the same day until April 1, 2013 when the payment reduction was increased to 50%.

Other Requirements for Payment

        Historically, outpatient rehabilitation services have been subject to scrutiny by the Medicare program for, among other things, medical necessity for services, appropriate documentation for services, supervision of therapy aides and students and billing for single rather than group therapy when services are furnished to more than one patient. CMS has issued guidance to clarify that services performed by a student are not reimbursed even if provided under "line of sight" supervision of the therapist. Likewise, CMS has reiterated that Medicare does not pay for services provided by aides regardless of the level of supervision. CMS also has issued instructions that outpatient physical and occupational therapy services provided simultaneously to two or more individuals by a practitioner should be billed as group therapy services.

Budget Control Act of 2011

        The Budget Control Act of 2011 (the "BCA of 2011"), enacted on August 2, 2011, increased the federal debt ceiling in connection with deficit reductions over the next ten years. The BCA of 2011 requires automatic reductions in federal spending by approximately $1.2 trillion split evenly between domestic and defense spending. Payments to Medicare providers are subject to these automatic spending reductions, subject to a 2% cap. On April 1, 2013, a 2% reduction to Medicare payments was implemented. The Bipartisan Budget Act of 2015, enacted on November 2, 2015, extends the 2% reductions to Medicare payments through fiscal year 2025.

Improving Medicare Post-Acute Care Transformation Act of 2014

        The Improving Medicare Post-Acute Care Transformation Act of 2014, enacted on October 6, 2014, requires our specialty hospitals to collect and report additional patient assessment data and clinical

Table of Contents

measures on each Medicare beneficiary who receives inpatient services in our facilities. Specialty hospitals must begin reporting this data no later than October 1, 2018. Within two years after that, CMS will begin making this data available to the public. Facilities that fail to report the required data will be subject to a 2% reduction in their payment rates. The reduction may result in an annual update of less than zero for the applicable rate year. However, any reduction is limited to the applicable fiscal year and is not cumulative. We expect CMS to publish additional regulations and guidance implementing this new law.

Specialty Hospital Medicaid Reimbursement

        The Medicaid program is designed to provide medical assistance to individuals unable to afford care. The program is governed by the Social Security Act of 1965, funded jointly by each individual state and the federal government, and administered by state agencies. Medicaid payments are made under a number of different systems, which include cost based reimbursement, prospective payment systems or programs that negotiate payment levels with individual hospitals. In addition, Medicaid programs are subject to statutory and regulatory changes, administrative rulings, interpretations of policy by the state agencies and certain government funding limitations, all of which may increase or decrease the level of program payments to our hospitals. Net operating revenues generated directly from the Medicaid program represented approximately 5%6% of our specialty hospitalhospitals net operating revenues for the year ended December 31, 2014.

Workers' Compensation

        Workers' compensation is a state mandated, comprehensive insurance program that requires employers to fund or insure medical expenses, lost wages and other costs resulting from work related injuries and illnesses. Workers' compensation benefits and arrangements vary on a state-by-state basis and are often highly complex. In some states, payment for services covered by workers' compensation programs are subject to cost containment features, such as requirements that all workers' compensation injuries be treated through a managed care program, or the imposition of payment caps. In addition, these workers' compensation programs may impose requirements that affect the operations of our outpatient rehabilitation services. Net operating revenues generated directly from workers' compensation programs represented approximately 17% of our net operating revenue from outpatient rehabilitation services and 1% of our net operating revenue from our specialty hospitals for the year ended December 31, 2014.2015.

Other Medicare Regulations

Medicare Quality Reporting

        The ACA established quality reporting requirements for LTCHs and IRFs. These programs are mandatory. For fiscal year 2014 and each subsequent year, LTCHs and IRFs that do not submit the required quality data will be subject to a 2% reduction in their annual payment update. The reduction can result in payment rates less than the prior year. However, the reduction will not carry over into the subsequent fiscal years.

Table of Contents

        The Physician Quality Reporting System, or "PQRS," is a CMS reporting program that uses a combination of incentive payments and payment reductions to promote reporting of quality information by "eligible professionals." Although physical therapists, occupational therapists and qualified speech-language therapists are generally able to participate in the PQRS program, therapy professionals for whose services we bill through our rehab agencies cannot participate because the Medicare claims processing systems currently cannot accommodate institutional providers such as rehab agencies. Eligible professionals, such as those of our therapy professionals for whose services we bill using their individual Medicare provider numbers, who do not satisfactorily report data on quality measures will be subject to a 2% reduction in their Medicare payment. Eligible professionals who satisfactorily report data on PQRS quality measures will earn a 0.5% incentive payment.

Medicare Productivity Adjustment

        The ACA implemented a separate annual productivity adjustment for the first time for hospital inpatient services beginning in fiscal year 2012 for LTCHs and IRFs. This provision applied a negative productivity adjustment to the market basket that is used to update the standard federal rate on an annual basis. The market basket does not currently account for increases in provider productivity that could reduce the actual cost of providing services (e.g., through new technology or fewer inputs). The productivity adjustment will equal the 10-year moving average of changes in the annual economy-wide private non-farm business multi-factor productivity. This is a statistic reported by the Bureau of Labor Statistics and updated in the spring of each year. While this adjustment will change each year, it is currently estimated that this adjustment to the market basket will be approximately minus 1.0% on average.

Table of Contents

Hospital Wage Index

        As part of the methodology for determining prospective payments to LTCHs and IRFs, CMS adjusts the standard payment amounts for area differences in hospital wage levels by a factor reflecting the relative hospital wage level in the geographic area of the hospital compared to the national average hospital wage level. This adjustment factor is the hospital wage index. CMS currently defines hospital geographic areas (labor market areas) based on the definitions of Core-Based Statistical Areas established by the Office of Management and Budget. The ACA calls for CMS to develop and present to Congress a comprehensive reform plan using Bureau of Labor Statistics data, or other data or methodologies, to calculate relative wages for each geographic area involved. In the preamble to the proposed rule for LTCH-PPS for fiscal year 2012, CMS solicited public comments on ways to redefine the geographic reclassification requirements to more accurately define labor markets. To date CMS has not presented a comprehensive reform plan to Congress.

Independent Payment Advisory Board

        The ACA established an independent board called the Independent Payment Advisory Board that is authorized to develop and submit proposals to the President and Congress to reduce Medicare spending to meet specified targets. The Independent Payment Advisory Board is precluded from submitting proposals that reduce Medicare payments prior to December 31, 2019 for providers, including LTCHs and IRFs, scheduled to receive a reduction in their payment updates in addition to the Medicare productivity adjustment (discussed above). The Independent Payment Advisory Board's proposals would go into effect automatically unless Congress enacts alternative legislation to achieve the required savings (with certain exceptions). The ACA authorized the Independent Payment Advisory Board to issue its first recommendations by January 2014 for implementation in 2015 if the Medicare per capita target growth rate is exceeded, but the CMS Office of the Actuary has determined that the Medicare spending target will not be triggered for 2015. To date, no Independent Payment Advisory Board members have been appointed, and there have been repeated legislative attempts to repeal the provision of the ACA authorizing the establishment of the Independent Payment Advisory Board.

Physician-Owned Hospital Limitations

        CMS regulations include a number of hospital ownership and physician referral provisions, including certain obligations requiring physician-owned hospitals to disclose ownership or investment interests held by the referring physician or his or her immediate family members. In particular, physician-owned hospitals must furnish to patients, on request, a list of physicians or immediate family members who own or invest in the hospital. Moreover, a physician-owned hospital must require all physician owners or investors who are also active members of the hospital's medical staff to disclose in writing their ownership or investment interests in the hospital to all patients they refer to the hospital. CMS can terminate the Medicare provider agreement of a physician-owned hospital if it fails to comply with these disclosure provisions or with the requirement that a hospital disclose in writing to all patients whether there is a physician on-site at the hospital 24 hours per day, seven days per week.

        Under the transparency and program integrity provisions of the ACA, the exception to the federal self-referral law, or "Stark law,Law," that permits physicians to refer patients to hospitals in which they have an ownership or investment interest has been dramatically curtailed. Only hospitals, including specialty hospitals, with physician ownership and a provider agreement in place on December 31, 2010 are exempt from the general ban on self-referral. Existing physician-owned hospitals are prohibited from increasing the percentage of physician ownership or investment interests held in the hospital after March 23, 2010. In addition, physician-owned hospitals are prohibited from increasing the number of licensed beds after March 23, 2010, unless meeting specific exceptions related to the hospital's location and patient population. In order to retain their exemption from the general ban on self-referrals, our physician-owned hospitals are required to adopt specific measures relating to conflicts of interest, bona fide investments and patient safety. As of December 31, 2014,2015, we operated 1110 hospitals that are owned in-part by physicians.

Provider and Employee Screening

        The ACA imposed new screening requirements on all Medicare providers, including LTCHs, IRFs and outpatient rehabilitation providers. The screening must include a licensure check and may include other procedures such as a criminal background check, fingerprinting, unscheduled and unannounced site visits, database checks, and other screening techniques CMS deems appropriate to prevent fraud, waste and abuse. Effective March 23, 2011, Medicare providers and suppliers submitting new enrollment applications or revalidating their existing enrollment status are required to pay a $500 application fee that is adjusted annually by the percentage change in the consumer price index. The ACA also imposed new disclosure requirements and authorizes surety bonds for the enrollment of new providers and suppliers.

        In addition, the ACA requires LTCHs to conduct national and state criminal background checks, including fingerprint checks of their employees and contractors who have (or may have) one-on-one contact with patients. Our LTCHs are prohibited from hiring or retaining workers with a history of patient or resident abuse.

Medicare Compliance Requirements and Penalties

        The ACA included new compliance requirements and increases existing penalties for non-compliance with federal law and the Medicare conditions of participation. In addition, Medicare claims will be paid only if submitted within 12 months. Penalties for submitting false claims and for submitting false statements material to a false claim will be increased. The Secretary will be granted the authority to suspend payments to a provider pending an investigation of credible allegations of fraud. Further,Furthermore, the Recovery Audit Contractor program has been extended to Medicare Parts C and D and Medicaid.

Other Healthcare Regulations

        Medicare Recovery Audit Contractors.    The Tax Relief and Health Care Act of 2006 instructed CMS to contract with third-party organizations, known as Recovery Audit Contractors, or "RACs," to identify Medicare underpayments and overpayments, and to authorize RACs to recoup any overpayments. The

Table of Contents

compensation paid to each RAC is based on a percentage of overpayment recoveries identified by the RAC. CMS has selected and entered into contracts with four RACs, each of which has begun their audit activities in specific jurisdictions. RAC audits of our Medicare reimbursement may lead to assertions that we have been overpaid, require us to incur additional costs to respond to requests for records and pursue the reversal of payment denials, and ultimately require us to refund any amounts determined to have been overpaid. We cannot predict the impact of future RAC reviews on our results of operations or cash flows.

        Fraud and Abuse Enforcement.    Various federal and state laws prohibit the submission of false or fraudulent claims, including claims to obtain payment under Medicare, Medicaid and other government healthcare programs. Penalties for violation of these laws include civil and criminal fines, imprisonment and exclusion from participation in federal and state healthcare programs. In recent years, federal and state government agencies have increased the level of enforcement resources and activities targeted at the healthcare industry. In addition, the federal False Claims Act and similar state statutes allow individuals to bring lawsuits on behalf of the government, in what are known as qui tam or "whistleblower" actions, alleging false or fraudulent Medicare or Medicaid claims or other violations of the statute. The use of these private enforcement actions against healthcare providers has increased dramatically in recent years, in part because the individual filing the initial complaint is entitled to share in a portion of any settlement or judgment. Revisions to the False Claims Act enacted in 2009 expanded significantly the scope of liability, provided for new investigative tools, and made it easier for whistleblowers to bring and maintain False Claims Act suits on behalf of the government. See "—Legal Proceedings."

        From time to time, various federal and state agencies, such as the Office of Inspector General of the Department of Health and Human Services, or "OIG," issue a variety of pronouncements, including fraud alerts, the OIG's Annual Work Plan and other reports, identifying practices that may be subject to

Table of Contents

heightened scrutiny. These pronouncements can identify issues relating to LTCHs, IRFs or outpatient rehabilitation services or providers. For example, in the OIG's 2013 Work Plan, the OIG indicated that it would study appropriateness of admissions to IRFs, the level of therapy provided in IRFs and whether IRFs received reduced payments for claims with patient assessment instruments that were transmitted to CMS outside defined time limits. The OIG stated in its 2014 Work Plan that it would study (1) readmission patterns in LTCHs to determine whether LTCHs are billing Medicare for higher paying new stays instead of interrupted stays and (2) the extent to which co-located LTCHs readmit patients from the providers with which they are co-located. The OIG issued a corresponding report in June of 2014 in which it recommended that CMS (1) review existing safeguards to determine whether additional action is needed to prevent inappropriate payments for interrupted stays, (2) conduct additional analysis to determine the extent to which financial incentives influence LTCHs' readmission decisions, (3) develop a system to enforce the 5-percent readmission threshold, (4) take appropriate action regarding LTCHs exhibiting certain readmission patterns, and (5) take appropriate action on inappropriate payments and overpayments to co-located LTCHs that exceed the 5-percent readmission threshold. Of these recommendations, CMS concurred with the OIG's recommendation that CMS (1) review existing safeguards to determine whether additional action is needed to prevent inappropriate payments for interrupted stays and (2) take appropriate action on inappropriate payments and overpayments to co-located LTCHs that exceed the 5-percent readmission threshold. . In the OIG's 2015 and 2016 Work Plan,Plans, the OIG announced its intent to estimate the national incidence of adverse and temporary harm events for Medicare beneficiaries receiving post-acute care in IRFs and LTCHs. As part of this review, the OIG intends to identify factors contributing to these events, determine the extent to which the events were preventable, and estimate the associated costs to Medicare. In the 2016 Work Plan the OIG also indicated it would review compliance with (1) various aspects of IRF PPS, including documentation required in support of claims paid by Medicare, (2) Medicare outlier payments to hospitals and whether CMS performed necessary reconciliations in a timely manner to enable Medicare contractors to perform final settlement of the hospitals' associated cost reports, and (3) hospital compliance with the Medicare provider-based rules. Our IRFs and LTCHs may be required to provide information related to adverse and temporary harm events in connection with this review.these reviews. We monitor government publications applicable to us to supplement and enhance our compliance efforts.

        We endeavor to conduct our operations in compliance with applicable laws, including healthcare fraud and abuse laws. If we identify any practices as being potentially contrary to applicable law, we will take appropriate action to address the matter, including, where appropriate, disclosure to the proper

Table of Contents

authorities, which may result in a voluntary refund of monies to Medicare, Medicaid or other governmental healthcare programs.

        Remuneration and Fraud Measures.    The federal anti-kickback statute prohibits some business practices and relationships under Medicare, Medicaid and other federal healthcare programs. These practices include the payment, receipt, offer or solicitation of remuneration in connection with, to induce, or to arrange for, the referral of patients covered by a federal or state healthcare program. Violations of the anti-kickback law may be punished by a criminal fine of up to $50,000 or imprisonment for each violation, or both, civil monetary penalties of $50,000 and damages of up to three times the total amount of remuneration, and exclusion from participation in federal or state healthcare programs.

        The Stark Law prohibits referrals for designated health services by physicians under the Medicare and Medicaid programs to other healthcare providers in which the physicians have an ownership or compensation arrangement unless an exception applies. Sanctions for violating the Stark Law include civil monetary penalties of up to $15,000 per prohibited service provided, assessments equal to three times the dollar value of each such service provided and exclusion from the Medicare and Medicaid programs and other federal and state healthcare programs. The statute also provides a penalty of up to $100,000 for a circumvention scheme. In addition, many states have adopted or may adopt similar anti-kickback or anti-self-referral statutes. Some of these statutes prohibit the payment or receipt of remuneration for the referral of patients, regardless of the source of the payment for the care. While we do not believe our arrangements are in violation of these prohibitions, we cannot assure you that governmental officials

Table of Contents

charged with the responsibility for enforcing the provisions of these prohibitions will not assert that one or more of our arrangements are in violation of the provisions of such laws and regulations.

        Provider-Based Status.    The designation "provider-based" refers to circumstances in which a subordinate facility (e.g., a separately certified Medicare provider, a department of a provider or a satellite facility) is treated as part of a provider for Medicare payment purposes. In these cases, the services of the subordinate facility are included on the "main" provider's cost report and overhead costs of the main provider can be allocated to the subordinate facility, to the extent that they are shared. As of December 31, 2014,2015, we operated 1714 specialty hospitals that were treated as provider-based satellites of certain of our other facilities, 164169 of the outpatient rehabilitation clinics we operated were provider-based and are operated as departments of the IRFs we operated, and we provide rehabilitation management and staffing services to hospital rehabilitation departments that may be treated as provider-based. These facilities are required to satisfy certain operational standards in order to retain their provider-based status.

        Effective January 1, 2017, outpatient rehabilitation services operated as provider-based and located at an off-campus outpatient department of a hospital, will be paid under the Medicare physician fee schedule, rather than the hospital outpatient prospective payment system, unless services at that location were billed as a department of a hospital prior to November 2, 2015. The 169 outpatient rehabilitation clinics we operated as departments of our IRFs as of November 2, 2015 are grandfathered and will continue to be paid under the hospital outpatient prospective payment system.

        Health Information Practices.    The Health Insurance Portability and Accountability Act of 1996, or "HIPAA," mandates the adoption of standards for the exchange of electronic health information in an effort to encourage overall administrative simplification and enhance the effectiveness and efficiency of the healthcare industry, while maintaining the privacy and security of health information. Among the standards that the Department of Health and Human Services has adopted or will adopt pursuant to HIPAA are standards for electronic transactions and code sets, unique identifiers for providers (referred to as National Provider Identifier), employers, health plans and individuals, security and electronic signatures, privacy and enforcement. If we fail to comply with the HIPAA requirements, we could be subject to criminal penalties and civil sanctions. The privacy, security and enforcement provisions of HIPAA were enhanced by the Health Information Technology for Economic and Clinical Health Act, or "HITECH," which was included in the ARRA. Among other things, HITECH establishes security breach notification requirements, allows enforcement of HIPAA by state attorneys general, and increases penalties for HIPAA violations.

        The Department of Health and Human Services has adopted standards in three areas in which we are required to comply that affect our operations.

Table of Contents

        Standards relating to the privacy of individually identifiable health information govern our use and disclosure of protected health information and require us to impose those rules, by contract, on any business associate to whom such information is disclosed.

        Standards relating to electronic transactions and code sets require the use of uniform standards for common healthcare transactions, including healthcare claims information, plan eligibility, referral certification and authorization, claims status, plan enrollment and disenrollment, payment and remittance advice, plan premium payments and coordination of benefits.

        Standards for the security of electronic health information require us to implement various administrative, physical and technical safeguards to ensure the integrity and confidentiality of electronic protected health information.

        We maintain a HIPAA committee that is charged with evaluating and monitoring our compliance with HIPAA. The HIPAA committee monitors regulations promulgated under HIPAA as they have been adopted to date and as additional standards and modifications are adopted. Although health information standards have had a significant effect on the manner in which we handle health data and communicate

Table of Contents

with payors, the cost of our compliance has not had a material adverse effect on our business, financial condition or results of operations. We cannot estimate the cost of compliance with standards that have not been issued or finalized by the Department of Health and Human Services.

        In addition to HIPAA, there are numerous federal and state laws and regulations addressing patient and consumer privacy concerns, including unauthorized access or theft of personal information. State statutes and regulations vary from state to state. Lawsuits, including class actions and action by state attorneys general, directed at companies that have experienced a privacy or security breach also can occur. Although our policies and procedures are aimed at complying with privacy and security requirements and minimizing the risks of any breach of privacy or security, there can be no assurance that a breach of privacy or security will not occur. If there is a breach, we may be subject to various penalties and damages and may be required to incur costs to mitigate the impact of the breach on affected individuals.

Compliance Program

Our Compliance Program

        In 1998, we voluntarily adopted our code of conduct. The code is reviewed and amended as necessary and is the basis for our company-wide compliance program. Our written code of conduct provides guidelines for principles and regulatory rules that are applicable to our patient care and business activities. These guidelines are implemented by a compliance officer, a compliance and internal audit committee, and employee education and training. We also have established a reporting system, auditing and monitoring programs, and a disciplinary system as a means for enforcing the code's policies.

Compliance and Internal Audit Committee

        Our compliance and internal audit committee is made up of members of our senior management and in-house counsel. The compliance and internal audit committee meets on a quarterly basis and reviews the activities, reports and operation of our compliance program. In addition, the HIPAA committee provides reports to the compliance and internal audit committee. The vice president of compliance and audit services meets with the compliance and internal audit committee on a quarterly basis to provide an overview of the activities and operation of our compliance program.

Operating Our Compliance Program

        We focus on integrating compliance responsibilities with operational functions. We recognize that our compliance with applicable laws and regulations depends upon individual employee actions as well as company operations. As a result, we have adopted an operations team approach to compliance. Our corporate executives, with the assistance of corporate experts, designed the programs of the compliance

Table of Contents

and internal audit committee. We utilize facility leaders for employee-level implementation of our code of conduct. This approach is intended to reinforce our company-wide commitment to operate in accordance with the laws and regulations that govern our business.

Compliance Issue Reporting

        In order to facilitate our employees' ability to report known, suspected or potential violations of our code of conduct, we have developed a system of reporting. This reporting, anonymous or attributable, may be accomplished through our toll-free compliance hotline, compliance e-mail address or our compliance post office box. The compliance officer and the compliance and internal audit committee are responsible for reviewing and investigating each compliance incident in accordance with the compliance and audit services department's investigation policy.

Table of Contents

Compliance Monitoring and Auditing / Comprehensive Training and Education

        Monitoring reports and the results of compliance for each of our business segments are reported to the compliance and internal audit committee on a quarterly basis. We train and educate our employees regarding the code of conduct, as well as the legal and regulatory requirements relevant to each employee's work environment. New and current employees are required to acknowledge and certify that the employee has read, understood and has agreed to abide by the code of conduct. Additionally, all employees are required to re-certify compliance with the code on an annual basis.

Policies and Procedures Reflecting Compliance Focus Areas

        We review our policies and procedures for our compliance program from time to time in order to improve operations and to ensure compliance with requirements of standards, laws and regulations and to reflect the ongoing compliance focus areas which have been identified by the compliance and internal audit committee.

Internal Audit

        In addition to and in support of the efforts of our compliance and audit department, during 2001 we established an internal audit function. The vice president of compliance and audit services manages the combined compliance and audit department and meets with the audit and compliance committee of the board of directors on a quarterly basis to discuss audit results and provide an overview of the activities and operation of our compliance program.

Item 1A.    Risk Factors.

        In addition to the factors discussed elsewhere in this Form 10-K, the following are important factors which could cause actual results or events to differ materially from those contained in any forward-looking statements made by or on behalf of us.

Risks Related to our Business

If there are changes in the rates or methods of government reimbursements for our services, our net operating revenues and profitability could decline.

        Approximately 47% of our net operating revenues for the year ended December 31, 2012, 46% of our net operating revenues for the year ended December 31, 2013, and 45% of our net operating revenues for the year ended December 31, 2014 and 37% of our net operating revenues for the year ended December 31, 2015 came from the highly regulated federal Medicare program.

        In recent years, through legislative and regulatory actions, the federal government has made substantial changes to various payment systems under the Medicare program. President Obama signed into law comprehensive reforms to the healthcare system, including changes to the methods for, and amounts of, Medicare reimbursement. Additional reforms or other changes to these payment systems, including modifications to the conditions on qualification for payment, bundling payments to cover both acute and post-acute care or the imposition of enrollment limitations on new providers, may be proposed or could be adopted, either by Congress or CMS. If revised regulations are adopted, the availability, methods and rates of Medicare reimbursements for services of the type furnished at our facilities could change. Some of these changes and proposed changes could adversely affect our business strategy, operations and financial results. In addition, there can be no assurance that any increases in Medicare reimbursement rates established by CMS will fully reflect increases in our operating costs.

        The BCA of 2011, enacted on August 2, 2011, increased the federal debt ceiling in connection with deficit reductions over the next ten years. The BCA of 2011 requires automatic reductions in federal spending by approximately $1.2 trillion split evenly between domestic and defense spending. Payments to Medicare providers are subject to these automatic spending reductions, subject to a 2% cap. On April 1, 2013 a 2% reduction to Medicare payments was implemented. The BBA of 2013 extended the automatic

Table of Contents

spending reductions through 2023. For2023 and the years ended December 31, 2014 and 2013, this reduction has reduced our net operating revenues and income from operations by approximately $30.0 million and $24.0 million, respectively.Bipartisan Budget Act of 2015 further extended the automatic spending reductions through fiscal year 2025.

We conduct business in a heavily regulated industry, and changes in regulations, new interpretations of existing regulations or violations of regulations may result in increased costs or sanctions that reduce our net operating revenues and profitability.

        The healthcare industry is subject to extensive federal, state and local laws and regulations relating to (1) facility and professional licensure, including certificates of need, (2) conduct of operations, including financial relationships among healthcare providers, Medicare fraud and abuse and physician self-referral, (3) addition of facilities and services and enrollment of newly developed facilities in the Medicare program, (4) payment for services and (5) safeguarding protected health information.

        Both federal and state regulatory agencies inspect, survey and audit our facilities to review our compliance with these laws and regulations. While our facilities intend to comply with existing licensing, Medicare certification requirements and accreditation standards, there can be no assurance that these regulatory authorities will determine that all applicable requirements are fully met at any given time. A determination by any of these regulatory authorities that a facility is not in compliance with these requirements could lead to the imposition of requirements that the facility takes corrective action, assessment of fines and penalties, or loss of licensure, Medicare certification or accreditation. These consequences could have an adverse effect on our company.

        In addition, there have been heightened coordinated civil and criminal enforcement efforts by both federal and state government agencies relating to the healthcare industry. The ongoing investigations

Table of Contents

relate to, among other things, various referral practices, cost reporting, billing practices, physician ownership and joint ventures involving hospitals. In the future, different interpretations or enforcement of these laws and regulations could subject us to allegations of impropriety or illegality or could require us to make changes in our facilities, equipment, personnel, services and capital expenditure programs. These changes may increase our operating expenses and reduce our operating revenues. If we fail to comply with these extensive laws and government regulations, we could become ineligible to receive government program reimbursement, suffer civil or criminal penalties or be required to make significant changes to our operations. In addition, we could be forced to expend considerable resources responding to any related investigation or other enforcement action.

Full implementation of the Medicare 25 Percent Rule applicable to LTCHs will have an adverse effect on our future net operating revenues and profitability.

        Under the 25 Percent Rule, the Medicare payment rate for LTCHs is subject to a downward payment adjustment if the percentage of Medicare patients discharged from an LTCH who were admitted from an individual referring hospital exceeds an applicable percentage admissions threshold during a particular cost reporting period. Cases admitted to an LTCH in excess of the applicable percentage admissions threshold are reimbursed at a rate comparable to that under IPPS. IPPS rates are generally lower than LTCH-PPS rates. Cases that reach outlier status in the discharging hospital do not count toward the limit and are paid under LTCH-PPS.

        LTCHs that are operated as HIHs or as HIH "satellites," are subject to payment reductions for those Medicare patients admitted from their host hospitals in excess of the applicable percentage admissions threshold and from other referring hospitals in excess of the applicable percentage admissions threshold. LTCHs that are operated as freestanding facilities are subject to a payment reduction for those Medicare patients admitted from other referring hospitals in excess of the applicable admissions threshold. Grandfathered HIHs are excluded from the Medicare percentage admissions threshold regulations.

        The SCHIP Extension Act, as amended by the ARRA, the ACA and the BBA of 2013, postponed the full application of the percentage admissions threshold for specific classifications of LTCHs. Full

Table of Contents

implementation of the Medicare percentage admissions thresholds under the 25 Percent Rule will not go into effect until cost reporting periods beginning on or after July 1, 2016 or October 1, 2016, depending on the specific classification of LTCH. See "Business — "Business—Government Regulations — Regulations—Overview of U.S. and State Government Reimbursements — Reimbursements—Long Term Acute Care Hospital Medicare Reimbursement — Reimbursement—25 Percent Rule."

        As of December 31, 2014,2015, we owned 8380 HIHs and satellite facilities of which three are grandfathered HIHs and are excluded from the percentage threshold regulations. Of the remaining 8077 HIHs and satellite facilities subject to a percentage admissions threshold for admissions from their host hospital; nine of these HIHs and satellite facilities were subject to a maximum 25% Medicare percentage admissions threshold for admissions from their host hospital, fourfive HIHs and satellite facilities are co-located with an MSA dominant hospital and were subject to a Medicare percentage admissions threshold of no more than 50%, nor less than 25%, 1918 of these HIHs and satellite facilities were co-located with a MSA dominant hospital or single urban hospital and were subject to a Medicare percentage admissions threshold of no more than 75%, 4644 of these HIHs and satellite facilities were subject to a maximum 50% Medicare admissions threshold, and twoone of these HIHs and satellite facilities werewas located in a rural area and werewas subject to a maximum 75% Medicare percentage admissions threshold. As of December 31, 2014,2015, we owned three grandfathered HIHs, all of which are excluded from the percentage admissions threshold regulations. As of December 31, 2014,2015, we owned 2928 free-standing LTCHs, which are not subject to the Medicare percentage admissions threshold until cost reporting periods beginning on or after July 1, 2017.2016.

        The BBA of 2013 requires CMS to report to Congress before October 2016 on the need for any further extensions or modifications of the extensions of the 25 Percent Rule. In addition, the BBA of 2013 requires MedPAC, an independent federal body that advises Congress on issues affecting the Medicare

program, to report to Congress by June 2019 on the need to continue applying the 25 Percent Rule, the effect of site-neutral payment on LTCHs and recommendations on how to change the site-neutral payment policy.

        Because these rules are complex and are based on the volume of Medicare admissions from other referring hospitals as a percent of our overall Medicare admissions, we cannot predict with any certainty the impact on our future net operating revenues and profitability of compliance with these regulations. We expect many of our LTCHs will experience an adverse financial impact when full implementation of the Medicare percentage admissions thresholds goes into effect. Our LTCHs have cost reporting periods that commence on various dates throughout the calendar year. Therefore, the application of the lower percentage admissions thresholds will be staggered and we would not realize the full impact of lower percentage admissions thresholds until 2017.

Expiration of the moratorium imposed on the payment adjustment for very short-stay cases in our LTCHs has reduced and will continue to reduce our future net operating revenues and profitability.

        On May 1, 2007, CMS published a new provision that changed the payment methodology for Medicare patients with a length of stay that is less than the IPPS comparable threshold. Beginning with discharges on or after July 1, 2007, for these very short-stay cases, the rule lowered the LTCH payment to a rate based on the general acute care hospital IPPS per diem. SSO cases with covered lengths of stay that exceed the IPPS comparable threshold would continue to be paid under the existing SSO payment policy. The SCHIP Extension Act and ACA prevented CMS from applying this change to SSO policy for a period of five years through December 28, 2012. The implementation of the payment methodology for very short-stay outliers discharged after December 29, 2012 has reduced and will continue to reduce our future net operating revenues and profitability.

If our LTCHs fail to maintain their certifications as LTCHs or if our facilities operated as HIHs fail to qualify as hospitals separate from their host hospitals, our net operating revenues and profitability may decline.

        As of December 31, 2014,2015, we operated 113109 LTCHs, 108 of which are currently certified by Medicare as LTCHs and five ofone which are in their demonstration period.is currently awaiting certification. LTCHs must meet certain conditions of participation to enroll in, and seek payment from, the Medicare program as an LTCH, including, among other things, maintaining an average length of stay for Medicare patients in excess of 25 days. An LTCH that fails to maintain this average length of stay for Medicare patients in excess of 25 days during a single cost reporting period is generally allowed an opportunity to show that it meets the length of stay criteria during thea subsequent cost reportingcure period. If the LTCH can show that it meets the length of stay criteria during this cure period, it will continue to be paid under the LTCH-PPS. If the LTCH again fails to meet the average length of stay criteria during the cure period, it will be paid under the general acute care IPPS at rates generally lower than the rates under the LTCH-PPS.

        Similarly, our HIHs must meet conditions of participation in the Medicare program, which include additional criteria establishing separateness from the hospital with which the HIH shares space. If our

Table of Contents

LTCHs or HIHs fail to meet or maintain the standards for certification as LTCHs, they will receive payment under the general acute care hospitals IPPS which is generally lower than payment under the system applicable to LTCHs. Payments at rates applicable to general acute care hospitals would result in our LTCHs receiving significantly less Medicare reimbursement than they currently receive for their patient services.

Table of Contents

Implementation of additional patient or facility criteria for LTCHs that limit the population of patients eligible for our hospitals' services or change the basis on which we are paid could adversely affect our net operating revenue and profitability.

        The BBA of 2013 establishes new payment limits for Medicare patients who do not meet specified criteria. Specifically, for Medicare patients discharged in cost reporting periods beginning on or after October 1, 2015, LTCHs will be reimbursed under LTCH-PPS only if, immediately preceding the patient's LTCH admission, the patient was discharged from a general acute care hospital paid under IPPS and the patient's stay included at least three days in an intensive care unit (ICU) or coronary care unit (CCU) or the patient is assigned to an MS-LTC-DRG for cases receiving at least 96 hours of ventilator services in the LTCH. In addition, to be paid under LTCH-PPS the patient's discharge from the LTCH may not include a principal diagnosis relating to psychiatric or rehabilitation services. For any Medicare patient who does not meet the new criteria, the LTCH will be paid a "site-neutral" payment rate, which will be the lower of (1) the IPPS comparable per-diem payment rate including any outlier payments, or (2) 100 percent of the estimated costs for services. For cost reporting periods beginning in fiscal year 2020,on or after October 1, 2019, payment for all discharges from an LTCH may be subject to the site-neutral payment limitation unless the number of discharges for which payment is made under the LTCH-PPS payment rate is greater than 50% of the total number of discharges for the LTCH. The application of the new site-neutral payment rates under LTCH-PPS may reduce our operating revenues.

        CMS requested public comments in May of 2013 on adoption of a payment adjustment based on whether a particular case qualifies as chronically critically ill/medically complex ("CCI/MC"). CMS indicated that it was considering a change to the LTCH-PPS payment policies that would limit full LTCH-PPS payment to those patients meeting the definition of CCI/MC while they were in an IPPS hospital inpatient setting and subsequently directly admitted to an LTCH. Payment for non-CCI/MC patients would be made at an "IPPS comparable amount," that is, an amount comparable to what would have been paid under the IPPS calculated as a per diem rate with total payments capped at the full IPPS MS-DRG payment rate.

        It is unclear how the adoption of the BBA of 2013 will impact regulatory or legislative proposals to change the LTCH-PPS payment policies. We cannot predict whether Congress or CMS will adopt additional patient-level criteria in the future or, if adopted, how such criteria would affect our LTCHs. Implementation of additional patient or facility criteria that may limit the population of patients eligible for our LTCHs' services or change the basis on which we are paid could adversely affect our net operating revenues and profitability.

Decreases in Medicare reimbursement rates received by our outpatient rehabilitation clinics, implementation of annual caps, and payment reductions applied to the second and subsequent therapy services may reduce our future net operating revenues and profitability.

        Our outpatient rehabilitation clinics receive payments from the Medicare program under a fee schedule. The Medicare physicianAccess and CHIP Reauthorization Act of 2015 requires that payments under the fee schedule rates are automatically updated annuallybe adjusted starting in 2019 based on the SGR formula, containedperformance in legislation. CMS estimated on November 13, 2014 thata new Merit-Based Incentive Payment System and, beginning April 1, 2015 the Medicare physician fee schedulein 2020, incentives for participation in alternative payment rates would be reduced by 21.2% as a resultmodels. The specifics of the SGR formula. The PAMA temporarily blocksMerit-Based Incentive Payment System and incentives for participation in alternative payment models will be subject to future notice and comment rule-making. It is unclear what impact, if any, the Merit-Based Incentive Payment System and incentives for participation in alternative payment reduction caused by the SGR formula through March 31, 2015models will have on our business and replaces it with a 0.5%operating results, but any resulting decrease in payment increase for services provided through December 31, 2014 and a 0% payment update from January 1, 2015 through March 31, 2015. If no further legislation is passed by Congress and signed by the President, the SGR formula will likelymay reduce our Medicare outpatient rehabilitation payment rates beginning April 1, 2015.future net operating revenues and profitability.

        Congress has established annual caps that limit the amount that can be paid (including deductible and coinsurance amounts) for outpatient therapy services rendered to any Medicare beneficiary. As directed by Congress in the DRA, CMS implemented an exception process for therapy expenses incurred in 2006.

Table of Contents

Under this process, a Medicare enrollee (or person acting on behalf of the Medicare enrollee) was able to request an exception from the therapy caps if the provision of therapy services was deemed to be medically necessary. Therapy cap exceptions were available automatically for certain conditions and on a case by case basis upon submission of documentation of medical necessity. The exception process has been extended by Congress several times. Most recently, the PAMAMedicare Access and CHIP Reauthorization Act of 2015 extends the exceptions process for outpatient therapy caps through MarchDecember 31, 2015.2017. The exception process will expire on April 1, 2015December 31, 2017 unless further extended by Congress. There can be no assurance that Congress will extend it further. To date, the implementation of the therapy caps has not had a material adverse effect on our business. However, if the exception process is not renewed, our future net operating revenues and profitability may decline.

        CMS adopted a multiple procedure payment reduction for therapy services in the final update to the Medicare physician fee schedule for calendar year 2011. Under the policy, the Medicare program pays 100% of the practice expense component of the therapy procedure or unit of service with the highest Relative Value Unit, and then reduces the payment for the practice expense component for the second and subsequent therapy procedures or units of service furnished during the same day for the same patient, regardless of whether those therapy services are furnished in separate sessions. In 2011 and 2012 the second and subsequent therapy service furnished during the same day for the same patient was reduced by 20% in office and other non institutional settings and by 25% in institutional settings. The American Taxpayer Relief Act of 2012 increased the payment reduction to 50% effective April 1, 2013. Should CMS adopt further increases in the payment reduction percentage our future net operating revenues and profitability would decline.

         The nature of the markets that Concentra serves may constrain its ability to raise prices at rates sufficient to keep pace with the inflation of its costs.

        Rates of reimbursement for work-related injury or illness visits in Concentra's occupational health services business are established through a legislative or regulatory process within each state that Concentra serves. Currently, 32 states have fee schedules pursuant to which all healthcare providers are uniformly reimbursed. The fee schedules are determined by each state and generally prescribe the maximum amounts that may be reimbursed for a designated procedure. In the states without fee schedules, healthcare providers are generally reimbursed based on usual, customary and reasonable rates charged in the particular state in which the services are provided. Given that Concentra does not control these processes, it may be subject to financial risks if individual jurisdictions reduce rates or do not routinely raise rates of reimbursement in a manner that keeps pace with the inflation of Concentra's costs of service.

        In Concentra's veteran's healthcare business, reimbursement rates are generally set according to the capitated monthly rate based on the number of then enrolled patients at that CBOC. Evolving legislative and regulatory changes aimed at improving veteran's access to care in the wake of Department of Veterans Affairs scandals (none of which involved Concentra's CBOCs) could result in fewer patients enrolling in CBOCs. Federal legislation that permits certain veterans to receive their health care outside of the Department of Veterans Affairs facilities, for example, may reduce demand for services at some of Concentra's CBOCs. Moreover, changes in the methods, manner or amounts of compensation payable for Concentra's services, including, amounts reimbursable to the CBOCs under its agreements with the Department of Veterans Affairs, due to legislative or other changes or shifting budget priorities could result in lower reimbursement for services provided at Concentra's CBOCs. Concentra may receive lower payments from the Veterans Health Administration if fewer eligible veterans are considered to live within the catchments of its CBOCs. These trends could have an adverse effect on our financial condition and results of operations.

Regulations limiting the diagnosis codes on the presumptive compliance list could adversely affect our net operating revenue and profitability.

        As of December 31, 2014,2015, we operated 1618 IRFs, all17 of which are currently certified by Medicare as IRFs.IRFs and one which is in the process of obtaining its certification. IRFs must meet certain conditions of participation to enroll in, and seek payment from, the Medicare program as an IRF. Among other things, at least 60% of the IRF's total inpatient population must require treatment for one or more of 13 conditions specified by regulation. This requirement is now commonly referred to as the "60% Rule." Compliance with the 60% Rule is demonstrated through a two step process. The first step is the "presumptive" method, in which patient diagnosis codes are compared to a "presumptive compliance" list. IRFs that fail to demonstrate compliance with the 60% Rule using this presumptive test may demonstrate compliance through a second step involving an audit of the facility's medical records to assess compliance.

        Effective October 1, 2015, CMS has announced that it will removeremoved a number of diagnosis codes from the presumptive compliance list including diagnosis codes in the following categories: non-specificnonspecific diagnosis codes, arthritis diagnosis codes, unilateral upper extremity amputations diagnosis codes, amputation status codes, prosthetic fitting and adjustment codes, some congenital anomalies diagnosis codes and other miscellaneous diagnosis codes. According to CMS, these conditions do not demonstrate the need for intensive inpatient rehabilitation services in the absence of additional facts that would have to be pulled from a patient's medical record. These diagnosis codes are scheduled to be removed from the presumptive compliance list beginning October 1, 2015. If an IRF does not demonstrate compliance with the 60% Rule by either the presumptive method or through a review of medical records, then the facility's classification as an IRF may be terminated at the start of its next cost reporting period causing the facility to be paid as a general acute care hospital under IPPS. By removing diagnosis codes from the presumptive compliance list our facilities may be required to demonstrate compliance with the 60% Rule through medical record reviews. If our IRFs fail to demonstrate compliance with the 60% Rule through either method and are classified as general acute care hospitals, our net operating revenue and profitability may be adversely affected.

As a result of increased post-payment reviews of claims we submit to Medicare for our services, we may incur additional costs and may be required to repay amounts already paid to us.

        We are subject to regular post-payment inquiries, investigations and audits of the claims we submit to Medicare for payment for our services. These post-payment reviews are increasing as a result of new government cost- containmentcost-containment initiatives, including enhanced medical necessity reviews for Medicare patients admitted to our specialty hospitals, and audits of Medicare claims under the Recovery Audit Contractor program. These additional post-payment reviews may require us to incur additional costs to respond to requests for records and to pursue the reversal of payment denials, and ultimately may require us to refund amounts paid to us by Medicare that are determined to have been overpaid.

Our facilities are subject to extensive federal and state laws and regulations relating to the privacy of individually identifiable information.

        HIPAA required the United States Department of Health and Human Services to adopt standards to protect the privacy and security of individually identifiable health-relatedhealth information. The department released final regulations containing privacy standards in December of 2000 and published revisions to the final regulations in August 2002. The privacy regulations extensively regulate the use and disclosure of individually identifiable health-relatedhealth information. The regulations also provide patients with significant new rights related to understanding and controlling how their health information is used or disclosed. The security regulations require healthcare providers to implement administrative, physical and technical practices to protect the security of individually identifiable health information that is maintained or transmitted electronically. HITECH, which was signed into law in February of 2009, enhanced the privacy, security and enforcement provisions of HIPAA by, among other things, establishing security breach notification requirements, allowing enforcement of HIPAA by state attorneys general, and increasing

Table of Contents

penalties for HIPAA violations. Violations of HIPAA or HITECH could result in civil or criminal penalties.

        In addition to HIPAA, there are numerous federal and state laws and regulations addressing patient and consumer privacy concerns, including unauthorized access or theft of personalpatient's identifiable health information. State statutes and regulations vary from state to state. Lawsuits, including class actions and action by state attorneys general, directed at companies that have experienced a privacy or security breach also can occur.

        In the conduct of our business, we process, maintain and transmit sensitive data, including our patient's individually identifiable health information. We have developed a comprehensive set of policies and procedures in our efforts to comply with HIPAA and other privacy laws. Our compliance officer, privacy officer and information security officer are responsible for implementing and monitoring compliance with our privacy and security policies and procedures at our facilities. We believe that the cost of our compliance with HIPAA and other federal and state privacy laws will not have a material adverse effect on our business, financial condition, results of operations or cash flows. However, there can be no assurance that a breach of privacy or security will not occur. If there is a breach, we may be subject to various lawsuits, penalties and damages and may be required to incur costs to mitigate the impact of the breach on affected individuals.

We may be adversely affected by a security breach of our, or our third-party vendor's, information technology systems, such as a cyber attack, that could compromise our information technologies, which may cause a violation of HIPAA or HITECH.HITECH and subject us to potential legal and reputational harm.

        In the normal course of business, our information technology systems hold sensitive patient information including patient demographic data, eligibility for various medical plans including Medicare and Medicaid and protected health information, which is subject to HIPAA and HITECH. Additionally, we utilize those same systems to perform our day-to-day activities, such as receiving referrals, assigning medical teams to patients, documenting medical information, maintaining an accurate record of all transactions, processing payments and processing payments.maintaining our employee's personal information. We also contract with third-party vendors to maintain and store our patient's individually identifiable health information. Numerous state and federal laws and regulations address privacy and information security concerns resulting from our access to our patient's and employee's personal information.

        Our information technology systems and those of our vendors that process, maintain and transmit such data are subject to computer viruses, cyber attacks or breaches. We adhere to policies and procedures designed to ensure compliance with HIPAA and other privacy and information security laws and require our third-party vendors to do so as well. If, however, we or our third-party vendors experience a breach, loss, or other compromise of unsecured protected health information or other personal information, such an event could result in significant civil and criminal penalties, lawsuits, reputational harm and increased costs to us, any of which could have a material adverse effect on our financial condition and results of operations.

        Furthermore, while our information technology systems, and those of our third-party vendors, are maintained with safeguards protecting against cyber-attacks,cyber attacks, including passive intrusion protection, firewalls and virus detection software. However,software, these safeguards do not ensure that a significant cyber attack could not occur. A cyber attack that bypasses our information technology security systems, or those of our third-party vendors, could cause the loss of protected health

information, or other data subject to privacy laws, the loss of proprietary business information, or a material disruption to our or a third-party vendor's information technology business systems resulting in a material adverse effect on our business, financial condition, results of operations or cash flows. In addition, our future results could be adversely affected due to the theft, destruction, loss, misappropriation or release of protected health information, other confidential data or proprietary business information, operational or business delays resulting from the

disruption of information technology systems and subsequent clean-up and mitigation activities, negative publicity resulting in reputation or brand damage with clients, members, or industry peers, or regulatory action taken as a result of such incident.

We may be adversely affected by negative publicity which can result in increased governmental and regulatory scrutiny and possibly adverse regulatory changes.

        Negative press coverage can result in increased governmental and regulatory scrutiny and possibly adverse regulatory changes. Adverse publicity and increased governmental scrutiny can have a negative impact on our reputation with referral sources and patients and on the morale and performance of our employees, both of which could adversely affect our businesses and results of operations.

Future acquisitions or expansions may use significant resources, may be unsuccessful and could expose us to unforeseen liabilities.

        As part of our growth strategy, we may pursue acquisitions of specialty hospitals, outpatient rehabilitation clinics and other related healthcare facilities and services.services, and increase the number of Concentra medical centers, onsite clinics and CBOCs that Concentra operates. These acquisitions or expansions, including the pending acquisition of Physiotherapy Associates Holdings, Inc. ("Physiotherapy), may involve significant cash expenditures, debt incurrence, additional operating losses and expenses and compliance risks that could have a material adverse effect on our financial condition and results of operations.

        We may not be able to successfully integrate acquired businesses, such as Physiotherapy, into ours, and therefore we may not be able to realize the intended benefits from an acquisition.acquisition or expansion. If we fail to successfully integrate acquisitions and expansions into our operations, our financial condition and results of operations may be materially adversely affected. Acquisitions could result in difficulties integrating acquired operations, technologies and personnel into our business. Such difficulties may divert significant financial, operational and managerial resources from our existing operations and make it more difficult to achieve our operating and strategic objectives. We may fail to retain employees or patients acquired through acquisitions, which may negatively impact the integration efforts. Acquisitions could also have a negative impact on our results of operations if it is subsequently determined that goodwill or other acquired intangible assets are impaired, thus resulting in an impairment charge in a future period. Further expansions may require substantial financial resources and management attention, and diverting these resources may negatively affect our financial results.

        In addition, acquisitions, such as Physiotherapy, and expansions involve risks that the acquired businesses or expanded operations will not perform in accordance with expectations; that we may become liable for unforeseen financial or business liabilities, of the acquired businesses, including liabilities for failure to comply with healthcare regulations; that the expected synergies associated with acquisitions or expansions will not be achieved; and that business judgments concerning the value, strengths and weaknesses of businesses acquired or expanded operations will prove incorrect, which could have an material adverse effect on our financial condition and results of operations.

         If we are not able to raise the financing for the acquisition of Physiotherapy and Physiotherapy terminates the merger agreement, we will be required to pay a termination fee.

        We intend to finance the acquisition of Physiotherapy with proceeds from a proposed senior secured incremental term facility under Select's existing credit facilities, for which JP Morgan Chase, N.A. has provided us with a debt commitment letter. Should the merger agreement be terminated by Physiotherapy under specified conditions, including circumstances where we are required to close the transaction under the merger agreement and there is a failure of the debt financing to be funded in accordance with the terms of the debt commitment letter, a reverse termination fee of $24.0 million would be payable by us to Physiotherapy.

Risks associated with our potential international operations.

        We mayintend to expand our operations into other countries. International operations are subject to risks that may materially adversely affect our business, results of operations and financial condition. The risks that our potential international operations would be subject to include, among other things: difficulties and costs relating to staffing and managing foreign operations; fluctuations in the value of foreign currencies; repatriation of cash from our foreign operations to the United States; foreign countries may impose additional withholding taxes or otherwise tax our foreign income; separate operating and financial systems; disaster recovery; and unexpected regulatory, economic and political changes in foreign markets. In addition to the foregoing, our potential international operations will face risks associated with complying

with laws governing our foreign business operations, including the U.S. Foreign Corrupt Practices Act and applicable regulatory requirements.

Future joint ventures may use significant resources, may be unsuccessful and could expose us to unforeseen liabilities.

        As part of our growth strategy, we may partner with large health care systems to provide post acute care services. These joint ventures may involve significant cash expenditures, debt incurrence, additional operating losses and expenses, and compliance risks that could have a material adverse effect on our financial condition and results of operations.

        A joint venture involves the combining of corporate cultures and mission. As a result, we may not be able to successfully operate a joint venture, and therefore we may not be able to realize the intended benefits. If we fail to successfully execute a joint venture relationship, our financial condition and results of operations may be materially adversely affected. A new joint venture could result in difficulties in combining operations, technologies and personnel. Such difficulties may divert significant financial, operational and managerial resources from our existing operations and make it more difficult to achieve our operating and strategic objectives. We may fail to retain employees or patients as a result of the integration efforts.

        A joint venture is operated through a board of directors that contains representatives of Select and other parties to the joint venture. We may not control the board or some actions of the board may require supermajority votes. As a result, the joint venture may elect certain actions that could have adverse effects on our financial condition and results of operations.

         Competition may limit our ability to acquire hospitals, clinics and medical centers and adversely affect our growth.

        We have historically faced limited competition in acquiring specialty hospitals and outpatient rehabilitation clinics, but we may face heightened competition in the future. In addition, significant merger and acquisition activity has occurred in Concentra's industry. Our competitors may acquire or seek to acquire many of the hospitals, clinics and medical centers that would be suitable acquisition candidates for us. This increased competition could hamper our ability to acquire companies, or such increased competition may cause us to pay a higher price than we would otherwise pay in a less competitive environment. Increased competition from both strategic and financial buyers could limit our ability to grow by acquisitions or make our cost of acquisitions higher and therefore decrease our profitability.

         If we fail to compete effectively with other hospitals, clinics, medical centers and healthcare providers in the local areas we serve, our net operating revenues and profitability may decline.

        The healthcare business is highly competitive, and we compete with other hospitals, rehabilitation clinics, medical centers and other healthcare providers for patients. If we are unable to compete effectively in the specialty hospital, outpatient rehabilitation and occupational health services businesses, our ability to retain customers and physicians, or maintain or increase our revenue growth, price flexibility, control




Table of Contents

over medical cost trends and marketing expenses may be compromised and our net operating revenues and profitability may decline.

        Many of our specialty hospitals operate in geographic areas where we compete with at least one other hospital that provides similar services.

        Our outpatient rehabilitation clinics face competition from a variety of local and national outpatient rehabilitation providers, including physician-owned physical therapy clinics, dedicated locally owned and managed outpatient rehabilitation clinics and hospital or university owned or affiliated ventures, as well as national and regional providers in select areas. Other competing outpatient rehabilitation clinics in local areas we serve may have greater name recognition and longer operating histories than our clinics. The managers of these competing clinics may also have stronger relationships with physicians in their communities, which could give them a competitive advantage for patient referrals. Because the barriers to entry are not substantial and current customers have the flexibility to move easily to new healthcare service providers, we believe that new outpatient physical therapy competitors can emerge relatively quickly.

        Concentra's primary competitors have typically been independent physicians, hospital emergency departments and hospital-owned or hospital-affiliated medical facilities. Because the barriers to entry in Concentra's geographic markets are not substantial and its current customers have the flexibility to move easily to new healthcare service providers, new competitors to Concentra can emerge relatively quickly. The markets for Concentra's consumer health and veteran's healthcare businesses are also fragmented and competitive. If Concentra's competitors are better able to attract patients or expand services at their facilities than Concentra is, Concentra may experience an overall decline in revenue. Similarly, competitive pricing pressures from our competitors could cause Concentra to lose existing or future CBOC contracts with the Department of Veterans Affairs, which may also cause Concentra to experience an overall decline in revenue.

Future cost containment initiatives undertaken by private third-party payors may limit our future net operating revenues and profitability.

        Initiatives undertaken by major insurers and managed care companies to contain healthcare costs affect the profitability of our specialty hospitals and outpatient rehabilitation clinics. These payors attempt to control healthcare costs by contracting with hospitals and other healthcare providers to obtain services on a discounted basis. We believe that this trend may continue and may limit reimbursements for healthcare services. If insurers or managed care companies from whom we receive substantial payments reduce the amounts they pay for services, our profit margins may decline, or we may lose patients if we choose not to renew our contracts with these insurers at lower rates.

If we fail to maintain established relationships with the physicians in the areas we serve, our net operating revenues may decrease.

        Our success is partially dependent upon the admissions and referral practices of the physicians in the communities our hospitals and our outpatient rehabilitation clinics serve, and our ability to maintain good relations with these physicians. Physicians referring patients to our hospitals and clinics are generally not our employees and, in many of the local areas that we serve, most physicians have admitting privileges at other hospitals and are free to refer their patients to other providers. If we are unable to successfully cultivate and maintain strong relationships with these physicians, our hospitals' admissions and clinics' businesses may decrease, and our net operating revenues may decline.

Changes in federal or state law limiting or prohibiting certain physician referrals may preclude physicians from investing in our hospitals or referring to hospitals in which they already own an interest.

        The Stark Law prohibits a physician who has a financial relationship with an entity from referring his or her Medicare or Medicaid patients to that entity for certain designated health services, including

Table of Contents

inpatient and outpatient hospital services. Under the transparency and program integrity provisions of the ACA, the exception to the Stark Law that previously permitted physicians to refer patients to hospitals in which they have an ownership or investment interest has been dramatically curtailed. Only hospitals,

Table of Contents

including specialty hospitals, with physician ownership and a provider agreement in place on December 31, 2010 are exempt from the general ban on self-referral. Existing physician- ownedphysician-owned hospitals are prohibited from increasing the percentage of physician ownership or investment interests held in the hospital after March 23, 2010. In addition, physician-owned hospitals are prohibited from increasing the number of licensed beds after March 23, 2010, unless meeting specific exceptions related to the hospital's location and patient population. In order to retain their exemption from the general ban on self- referrals,self-referrals, our physician owned hospitals are required to adopt specific measures relating to conflicts of interest, bona fide investments and patient safety. Furthermore, initiatives are underway in some states to restrict physician referrals to physician-owned hospitals. Currently, 1110 of our consolidating hospitals have physicians as minority owners. The aggregate net operating revenue of these 1110 hospitals was $194.1$176.9 million for the year ended December 31, 2014,2015, or approximately 6.3%4.7% of our consolidated net operating revenues for the year ended December 31, 2014.2015. The range of physician minority ownership of these 1110 hospitals was 2.1% to 49.0%38.7% as of the year ended December 31, 2014.2015. There can be no assurance that new legislation or regulation prohibiting or limiting physician referrals to physician-owned hospitals will not be successfully enacted in the future. If such federal or state laws are adopted, among other outcomes, physicians who have invested in our hospitals could be precluded from referring to, investing in or continuing to be physician owners of a hospital. In addition, expansion of our physician- ownedphysician-owned hospitals may be limited, and the revenues, profitability and overall financial performance of our hospitals may be negatively affected.

We could experience significant increases to our operating costs due to shortages of healthcare professionals or union activity.

        Our specialty hospitals are highly dependent on nurses, and our outpatient rehabilitation division is highly dependent on therapists for patient care.care, and Concentra is highly dependent upon the ability of its affiliated professional groups to recruit and retain qualified physicians and other licensed providers. The market for qualified healthcare professionals is highly competitive. We have sometimes experienced difficulties in attracting and retaining qualified healthcare personnel. We cannot assure you we will be able to attract and retain qualified healthcare professionals in the future. Additionally, the cost of attracting and retaining qualified healthcare personnel may be higher than we anticipate, and as a result, our profitability could decline.

        In addition, U.S. healthcare providers are continuing to see an increase in the amount of union activity. Though we cannot predict the degree to which we will be affected by future union activity, there are continuing legislative proposals that could result in increased union activity. We could experience an increase in labor and other costs from such union activity.

Competition may limit our ability to acquire hospitals and clinics and adversely affect our growth.

        We have historically faced limited competition in acquiring specialty hospitals and outpatient rehabilitation clinics, but we may face heightened competition in the future. Our competitors may acquire or seek to acquire many of the hospitals and clinics that would be suitable acquisition candidates for us. This increased competition could hamper our ability to acquire companies, or such increased competition may cause us to pay a higher price than we would otherwise pay in a less competitive environment. Increased competition from both strategic and financial buyers could limit our ability to grow by acquisitions or make our cost of acquisitions higher and therefore decrease our profitability.

If we fail to compete effectively with other hospitals, clinics and healthcare providers in the local areas we serve, our net operating revenues and profitability may decline.

        The healthcare business is highly competitive, and we compete with other hospitals, rehabilitation clinics and other healthcare providers for patients. If we are unable to compete effectively in the specialty hospital and outpatient rehabilitation businesses, our net operating revenues and profitability may decline. Many of our specialty hospitals operate in geographic areas where we compete with at least one other hospital that provides similar services. Our outpatient rehabilitation clinics face competition from a variety of local and national outpatient rehabilitation providers. Other outpatient rehabilitation clinics in local

areas we serve may have greater name recognition and longer operating histories than our clinics. The managers of these clinics may also have stronger relationships with physicians in their communities, which could give them a competitive advantage for patient referrals.

Our business operations could be significantly disrupted if we lose key members of our management team.

        Our success depends to a significant degree upon the continued contributions of our senior officers and other key employees, and our ability to retain and motivate these individuals. We currently have employment agreements in place with fourthree executive officers and change in control agreements and/or non-competition agreements with several other officers. Many of these individuals also have significant equity ownership in our company. We do not maintain any key life insurance policies for any of our employees. The loss of the services of any of these individuals could disrupt significant aspects of our business, could prevent us from successfully executing our business strategy and could have a material adverse affect on our results of operations.

         In conducting our business, we are required to comply with applicable laws regarding fee-splitting and the corporate practice of medicine.

        Some states prohibit the "corporate practice of medicine" that restricts business corporations from practicing medicine through the direct employment of physicians or from exercising control over medical decisions by physicians. Some states similarly prohibit the "corporate practice of therapy." The laws relating to corporate practice vary from state to state and are not fully developed in each state in which we have facilities. Typically, however, professional corporations owned and controlled by licensed professionals are exempt from corporate practice restrictions and may employ physicians or therapists to furnish professional services. Also, in some states hospitals are permitted to employ physicians.

        Some states also prohibit entities from engaging in certain financial arrangements, such as fee-splitting, with physicians or therapists. The laws relating to fee-splitting also vary from state to state and are not fully developed. Generally, these laws restrict business arrangements that involve a physician or therapist sharing medical fees with a referral source, but in some states these laws have been interpreted to extend to management agreements between physicians or therapists and business entities under some circumstances.

        We believe that the Company's current and planned activities do not constitute fee-splitting or the unlawful corporate practice of medicine as contemplated by these state laws. However, there can be no assurance that future interpretations of such laws will not require structural and organizational modification of our existing relationships with the practices. If a court or regulatory body determines that we have violated these laws or if new laws are introduced that would render our arrangements illegal, we could be subject to civil or criminal penalties, our 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 physicians and other licensed providers.

         If Concentra is unable to implement and enhance its information systems in a manner that leverages its knowledge of the workers' compensation market and or more efficiently process and manage claims, results may be adversely affected.

        To leverage its knowledge of workplace injuries, treatment protocols, outcomes data and complex regulatory provisions related to the workers' compensation market, Concentra must continue to implement and enhance information systems that can analyze its data related to the workers' compensation industry. Concentra frequently upgrades existing operating systems and is updating other information systems upon which it relies. Concentra has detailed implementation schedules for these projects that require extensive involvement from its operational, technological and financial personnel. Delays or other problems Concentra might encounter in implementing these projects could adversely affect its ability to deliver streamlined patient care and outcome reporting to its customers.

        In addition, Concentra expects that a considerable amount of its future growth will depend on its ability to process and manage claims data more efficiently and to provide more meaningful healthcare information to customers and payors of healthcare. There can be no assurance that Concentra's current data processing capabilities will be adequate for its future growth, that it will be able to efficiently upgrade its systems to meet future demands, or that it will be able to develop, license or otherwise acquire software to address these market demands as well or as timely as its competitors.

         If the frequency of workplace injuries and illnesses continues to decline, Concentra's results may be negatively affected.

        Approximately 52% of Concentra's revenue in 2015 was generated from the treatment or review of workers' compensation claims. In the past decade, the number of workers' compensation claims has decreased, which Concentra primarily attributes to improvements in workplace safety, improved risk management by employers and changes in the type and composition of jobs. During the economic




Table of Contents

downturn, the number of employees with workers' compensation insurance substantially decreased. Although the number of covered employees has increased more in recent years as the employment rate has increased, adverse economic conditions can cause the number of covered employees to decline which can cause further declines in workers' compensation claims. There may also be a decrease in claims because more workers have access to health insurance since the enactment of the ACA and are less likely to file worker's compensation claims. In addition, because of the greater access to health insurance and the fact that the U.S. economy has continued to shift from a manufacturing-based to a service-based economy along with general improvements in workplace safety, workers are generally healthier and less prone to work injuries. Increases in employer-sponsored wellness and health promotion programs, spurred in part by the ACA, have led to fitter and healthier employees who may be less likely to injure themselves on the job. Concentra's business model is based, in part, on its ability to expand its relative share of the market for the treatment and review of claims for workplace injuries and illnesses. If workplace injuries and illnesses decline at a greater rate than the increase in total employment or if total employment declines at a greater rate than the increase in incident rates, the number of claims in the workers' compensation market will decrease and may adversely affect Concentra's business.

         If Concentra loses several significant employer customers, its results may be adversely affected.

        Concentra's results may decline if it loses several significant employer customers in a short period. Most of Concentra's customer agreements permit either party to terminate without cause upon 30, 60 or 90 days' prior written notice. If several significant employer customers terminate, or do not renew or extend their agreements with Concentra, its results could be adversely affected. One or more of Concentra's significant employer customers could be acquired. Additionally, Concentra could lose significant employer customers due to competitive pricing pressures or other reasons. The loss of several significant employer customers could cause a material decline in Concentra's profitability and operating performance.

         We may not receive payment from some of our patients because of their financial circumstances.

        Some of our patients may not have significant financial resources, liquidity or access to capital. If these patients experience financial difficulties they may be unable to pay for the healthcare services that we will provide, including their copays or deductibles. A significant deterioration in general or local economic conditions could have a material adverse effect on the financial health of our patients, which may adversely affect our financial condition and results of operations.

Significant legal actions could subject us to substantial uninsured liabilities.

        Physicians, hospitals and other healthcare providers have become subject to an increasing number of legal actions alleging malpractice, product liability or related legal theories. Many of these actions involve large claims and significant defense costs. We are also subject to lawsuits under federal and state whistleblower statutes designed to combat fraud and abuse in the healthcare industry. These whistleblower lawsuits are not covered by insurance and can involve significant monetary damages and award bounties to private plaintiffs who successfully bring the suits. See "Legal Proceedings" and Note 14 in our audited consolidated financial statements.

        We currently maintain professional malpractice liability insurance and general liability insurance coverages under a combination of policies with a total annual aggregate limit of $30.0$35.0 million. Our insurance for the professional liability coverage is written on a "claims-made" basis and our commercial general liability coverage is maintained on an "occurrence" basis. These coverages apply after a self-insured retention of $2.0 million per medical incident for professional liability claims and $2.0 million per occurrence for general liability claims. We review our insurance program annually and may make adjustments to the amount of insurance coverage and self-insured retentions in future years. In addition, our insurance coverage does not generally cover punitive damages and may not cover all claims against us. See "Business — "Business—Government Regulations — Regulations—Other Healthcare Regulations."

Concentration of ownership among our existing executives and directors may prevent new investors from influencing significant corporate decisions.

        Our executives and directors, beneficially own, in the aggregate, approximately 19.9%19.6% of Holdings' outstanding common stock as of February 1, 2015.2016. As a result, these stockholders have significant control over our management and policies and are able to exercise influence over all matters requiring stockholder approval, including the election of directors, amendment of our certificate of incorporation and approval of significant corporate transactions. The directors elected by these stockholders are able to make decisions affecting our capital structure, including decisions to issue additional capital stock, implement stock repurchase programs and incur indebtedness. This influence may have the effect of deterring hostile takeovers, delaying or preventing changes in control or changes in management, or limiting the ability of our other stockholders to approve transactions that they may deem to be in their best interest.

Risks Related to our Capital Structure

         If WCAS and the other members of Group Holdings exercise their Put Right, it may have an adverse effect on our liquidity. Additionally, we may not have adequate funds to pay amounts due in connection with the Put Right, if exercised, in which case we would be required to issue Holdings' common stock to purchase interests of Group Holdings and our stockholder's ownership interest will be diluted.

        Pursuant to the Amended and Restated Limited Liability Company Agreement of Group Holdings, WCAS and the other members of Group Holdings have a put right (the "Put Right") with respect to their equity interests in Group Holdings. If a Put Right is exercised by WCAS, Select will be obligated to purchase up to 33¹/3% of the equity interests of Group Holdings that WCAS purchased on June 1, 2015, at a purchase price based on a valuation of Group Holdings performed by an investment bank to be mutually agreed between Select and WCAS, which valuation will be based on certain precedent transactions using multiples of EBITDA and capped at an agreed upon multiple of EBITDA. Select has the right to elect to pay the purchase price in cash or in shares of Holdings' common stock. WCAS may first exercise its Put Right after June 1, 2018, and then may exercise its Put Right again annually during each fiscal year thereafter. If WCAS exercises its Put Right, the other members of Group Holdings may elect to sell to Select, on the same terms as WCAS, a percentage of their equity interests of Group Holdings that such member purchased on June 1, 2015, up to but not exceeding the percentage of its initial equity interests that WCAS has determined to sell to Select in the exercise of its Put Right.

        Furthermore, WCAS and the other members of Group Holdings will have a put right with respect to their equity interest in Group Holdings in the event Holdings or Select experiences a change of control that has not been previously approved by WCAS and which results in change in the senior management of Select (an "SEM COC Put Right"). If an SEM COC Put Right is exercised by WCAS, WCAS and each other member of Group Holdings will be obligated to sell all (but not less than all) of their equity interests in Group Holdings to Select, at a purchase price based on a valuation of Group Holdings performed by an investment bank to be mutually agreed between Select and WCAS, which valuation will be based on certain precedent transactions using multiples of EBITDA and capped at an agreed upon multiple of EBITDA.

        We may not have sufficient funds, borrowing capacity or other capital resources available to pay for the interests of Group Holdings in cash if WCAS and the other members of Group Holdings exercise their Put Rights or maybe prohibited from doing so under the terms of our debt agreements. Such lack of available funds upon the exercising of the Put Rights would force us to issue stock at a time we might not otherwise desire to do so in order to purchase the interests of Group Holdings. To the extent that the interests of Group Holdings are purchased by issuing shares of our common stock, the increase in the number of shares of our common stock issued and outstanding may depress the price of our common stock and our stockholders will experience dilution in their respective percentage ownership in us. In addition, shares issued to purchase the interests in Group Holdings will be valued at the twenty-one trading day




Table of Contents

volume-weighted average sales price of such shares for the period beginning ten trading days immediately preceding the first public announcement of the Put Right being exercised and ending ten trading days immediately following such announcement. Because the value of the common stock issued to purchase the interests in Group Holdings is, in part, determined by the sales price of our common stock following the announcement that the Put Right is being exercised, which may cause the sales price of our common stock to decline, the amount of common stock we may have to issue to purchase the interests in Group Holdings may increase, resulting in further dilution to our existing stockholders.

Our substantial indebtedness may limit the amount of cash flow available to invest in the ongoing needs of our business.

        We have a substantial amount of indebtedness. As of December 31, 2014, we2015, Select had approximately $1,553.0$1,768.7 million of total indebtedness.indebtedness excluding the debt at Concentra. Taking into account the indebtedness under the Concentra credit facilities (as defined below), which is nonrecourse to Select, our total indebtedness at December 31, 2015 was $2,423.9 million. For the years ended December 31, 2012, December 31, 2013 and

Table of Contents

December 31, 2014, weSelect paid cash interest of $80.7 million, $89.1 million and $78.8 million, respectively,respectively. For the year ended December 31, 2015, Select paid cash interest, including cash interest paid by Concentra on our indebtedness.

Concentra's indebtedness, of $103.2 million. Our indebtedness could have important consequences to you. For example, it:

•

requires us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, reducing the availability of our cash flow to fund working capital, capital expenditures, development activity, acquisitions and other general corporate purposes;



•

increases our vulnerability to adverse general economic or industry conditions;



•

limits our flexibility in planning for, or reacting to, changes in our business or the industries in which we operate;



•

makes us more vulnerable to increases in interest rates, as borrowings under our senior secured credit facilities are at variable rates;



•

limits our ability to obtain additional financing in the future for working capital or other purposes; and



•

places us at a competitive disadvantage compared to our competitors that have less indebtedness.

        Any of these consequences could have a material adverse effect on our business, financial condition, results of operations, prospects and ability to satisfy our obligations under our indebtedness. In addition, there would be a material adverse effect on our business, financial condition, results of operations and cash flows if we were unable to service our indebtedness or obtain additional financing, as needed.

See "Management's Discussion and Analysis of Financial Condition and Results of Operations — Operations—Liquidity and Capital Resources."

Our senior secured credit facilities and the indenture governing Select's 6.375% senior notes require Selectus to comply with certain financial covenants and obligations, the default of which may result in the acceleration of certain of our indebtedness.

        In the case of an event of default under the agreements governing our indebtedness, the lenders under these agreements could elect to declare all amounts borrowed, together with accrued and unpaid interest and other fees, to be due and payable. If we are unable to obtain a waiver from the requisite lenders under such circumstances, the lenders could exercise their rights as described above, then our financial condition and results of operations could be adversely affected and we could become bankrupt or insolvent.

        The senior securedSelect credit facilities (as defined below) require Select to maintain a leverage ratio (based upon the ratio of indebtedness to consolidated EBITDA as defined in the agreement), which is tested quarterly and becomes more restrictive over time.quarterly. The senior securedSelect credit facilities also prohibit Select from making capital expenditures in excess of $125.0 million in any fiscal year (subject to a 50% carry-over provision). Failure to comply with these covenants would result in an event of default under the senior securedSelect credit facilities and, absent a waiver or an amendment from the lenders, preclude Select from making further borrowings under theits revolving credit facility and permit the lenders to accelerate all outstanding borrowings under the senior securedSelect credit facilities.

        In addition,The Concentra first lien credit agreement (as defined below) requires Concentra to maintain a leverage ratio (based upon the indenture governing Select's 6.375% senior notes also contains covenants.ratio of indebtedness for money borrowed to consolidated EBITDA) of 5.25 to 1.00, which is tested quarterly, but only if Revolving Exposure (as defined in the Concentra credit facilities (as defined below)) exceeds 30% of Revolving Commitments (as defined in the Concentra credit facilities) on such day. Failure to comply with those covenantsthis covenant would result in an event of default under the indentureConcentra revolving facility (as defined below) only and, absent a waiver or an amendment from the lenders, preclude Concentra from making further borrowings under the Concentra revolving facility and permit the trustee or holders of 25% of the noteslenders to accelerate all outstanding 6.375% senior notesborrowings under the indenture.Concentra revolving facility. Upon such acceleration, Concentra's failure to comply with the financial covenant would result in an Event of Default (as defined in the Concentra credit facilities) with respect to the Concentra first lien term loan (as defined below).

        The Concentra credit facilities also contain a number of affirmative and restrictive covenants, including limitations on mergers, consolidations and dissolutions; sales of assets; investments and acquisitions; indebtedness; liens; affiliate transactions; and dividends and restricted payments. The Concentra credit facilities contain events of default for non-payment of principal and interest when due (subject to a grace period for interest), cross-default and cross-acceleration provisions and an event of default that would be triggered by a change of control.

        As of December 31, 2014,2015, Select was required to maintain its leverage ratio (its ratio of total indebtedness to consolidated EBITDA for the prior four consecutive fiscal quarters) at less than 5.005.75 to 1.00. For the four consecutive fiscal quarters ended December 31, 2014,2015, Select's leverage ratio was 4.184.78 to 1.00.

        While Select haswe have never defaulted on compliance with any of theseour financial covenants, itsour ability to comply with these ratios in the future may be affected by events beyond itsour control. Inability to comply with the required financial covenants could result in a default under our senior secured credit facilities and indenture.indebtedness. In the event of any default under our senior securedSelect's credit facilities, the lenders under our senior secured credit facilities could elect to terminate borrowing commitments and declare all borrowings outstanding, together with accrued and unpaid interest and other fees, to be immediately due and payable. In the event of any default under ourSelect's indenture, the trustee or holders of 25% of the notes could declare all outstanding 6.375% senior notes immediately due and payable.

         Payment of interest on, and repayment of principal of, our indebtedness is dependent in part on cash flow generated by our subsidiaries.

        Payment of interest on, and repayment of principal of our indebtedness will be dependent in part upon cash flow generated by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Our subsidiaries may not be able to, or be permitted to, make distributions to enable us to make payments in respect of our indebtedness. For example, as a general matter, Concentra is restricted from paying dividends under the Concentra credit facilities and therefore we cannot rely on Concentra's cash flow to repay Select's indebtedness. Each of our subsidiaries is a distinct legal entity and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required principal and interest payments on our indebtedness. In addition, any payment of interest, dividends, distributions, loans or advances by our subsidiaries to us could be subject to

Table of Contents

restrictions on dividends or repatriation of distributions under applicable local law, monetary transfer restrictions and foreign currency exchange regulations in the jurisdictions in which the subsidiaries operate or under arrangements with local partners. Furthermore, the ability of our subsidiaries to make such payments of interest, dividends, distributions, loans or advances may be contested by taxing authorities in the relevant jurisdictions.

Despite our substantial level of indebtedness, we and our subsidiaries may be able to incur additional indebtedness. This could further exacerbate the risks described above.

        We and our subsidiaries may be able to incur additional indebtedness in the future. Although our senior securedthe Select credit facilities and the Concentra credit facilities contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the indebtedness incurred in compliance with these restrictions could be substantial. Also, these restrictions do not prevent us or our subsidiaries from incurring obligations that do not constitute indebtedness. As of December 31, 2014, we2015, Select had $249.7$116.1 million of revolving loan availability under our senior secured credit facilitiesthe Select revolving facility (as defined below) (after giving effect to $40.3$38.9 million of outstanding letters of credit) and Concentra had $39.0 million of availability under the Concentra revolving facility (after giving effect to $6.0 million of outstanding letters of credit). In addition, to the extent new debt is added to ourus and our subsidiaries' current debt levels, the substantial leverage risks described above would increase.

         Concentra's inability to meet the conditions and payments under the Concentra credit facilities, although non-recourse to Select, could jeopardize Select's equity contribution to Group Holdings.

        Select is not a party to the Concentra credit facilities and is not an obligor with respect to Concentra's debt under such agreements; however, if Concentra fails to meet its obligations and defaults on the Concentra credit facilities, a portion of or all of Select's equity investment in Group Holdings, the indirect parent company of Concentra, could be at risk of loss.

Item 3.    Legal Proceedings.

        The Company is a party to various legal actions, proceedings and claims (some of which are not insured), and regulatory and other governmental audits and investigations in the ordinary course of its business. The Company cannot predict the ultimate outcome of pending litigation, proceedings and regulatory and other governmental audits and investigations. These matters could potentially subject the Company to sanctions, damages, recoupments, fines and other penalties. The Department of Justice, CMS or other federal and state enforcement and regulatory agencies may conduct additional investigations

related to the Company's businesses in the future that may, either individually or in the aggregate, have a material adverse effect on the Company's business, financial position, results of operations and liquidity.

        To address claims arising out of the operations of the Company's specialty hospitals and outpatient rehabilitation facilities, the Company maintains professional malpractice liability insurance and general liability insurance, subject to self-insured retention of $2.0 million per medical incident for professional liability claims and $2.0 million per occurrence for general liability claims. The Company also maintains umbrella liability insurance covering claims which, due to their nature or amount, are not covered by or not fully covered by the Company's other insurance policies. These insurance policies also do not generally cover punitive damages and are subject to various deductibles and policy limits. Significant legal actions, as well as the cost and possible lack of available insurance, could subject the Company to substantial uninsured liabilities. In the Company's opinion, the outcome of these actions, individually or in the aggregate, will not have a material adverse effect on its financial position, results of operations, or cash flows.

        Healthcare providers are subject to lawsuits under the qui tam provisions of the federal False Claims Act. Qui tam lawsuits typically remain under seal (hence, usually unknown to the defendant) for some time while the government decides whether or not to intervene on behalf of a private qui tam plaintiff (known as a relator) and take the lead in the litigation. These lawsuits can involve significant monetary damages and penalties and award bounties to private plaintiffs who successfully bring the suits. The Company has been a defendant in these cases in the past, and may be named as a defendant in similar cases from time to time in the future.

        On January 8, 2013,October 19, 2015, the plaintiff-relators filed a federal magistrate judge unsealed anSecond Amended Complaint in United States of America,ex rel. Tracy Conroy, Pamela Schenk and the State of Indiana, ex rel. Doe I, Doe II and Doe IIILisa Wilson v. Select Medical Corporation, Select Specialty Hospital-Evansville, Hospital—Evansville, Physician Investment Corporation,LLC ("SSH-Evansville"), Select Employment Services, Inc., and Dr. Richard Sloan and Dr. Jeffrey Selby.Sloan. The Amended Complaint, which was served on the Company on February 15, 2013,case is a civil action filed under seal on September 28, 2012 in the United States District Court for the Southern District of Indiana by private plaintiff-relators on behalf of the United States and the State of Indiana under the federal False Claims Act and Indiana False Claims and Whistleblower Protection Act. Although the Amended Complaint identified the relators by fictitious pseudonyms, on March 28, 2013, the relators filed a Notice identifying themselves asThe plaintiff-relators are the former CEO at the Company's long term acute care hospital in Evansville, Indiana ("SSH-Evansville") and two former case managers at SSH-Evansville. The namedSSH-Evansville, and the defendants currently include the Company, SSH-Evansville, a subsidiary of the Company serving as common paymaster for its employees, and two physiciansa physician who have practicedpractices at SSH-Evansville. On March 26, 2013, the defendants, relatorsThe plaintiff-relators allege that that SSH-Evansville discharged patients too early or held patients too long, improperly discharged patients to and the United States filed a joint motion seeking areadmitted them from short stay of the proceedings, in which the United States notified the court that its investigation has not been completedhospitals, up-coded diagnoses at admission, and therefore it is not yet able to decide whether or not to intervene, and on March 29, 2013, the magistrate judge granted the motion and stayed all deadlines in the case for 90 days. The court has subsequently granted additional motions filed by the United States to continue the stay, and the current stay extends through March 16, 2015.

        As previously disclosed, the Company and SSH-Evansville produced documents in response to various government subpoenas and demands relating to SSH-Evansville. In September 2014, representatives of the United States Attorney's Office for the Southern District of Indiana and the Department of Justice informed the Company that, while the United States has not yet decided whether to intervene in the case, its investigation is continuing concerning the allegation that SSH-Evansville admitted patients for whom long-term acute care was not medically necessary. They also allege that the defendants engaged in retaliation in violation of federal and state law. The Second Amended Complaint replaces a prior complaint that was filed under seal on September 28, 2012 and served on the Company on February 15, 2013, after a federal magistrate judge unsealed it on January 8, 2013. All deadlines in the case had been stayed after the seal was lifted in order to allow the government time to complete its investigation and to decide whether or not to intervene. On June 19, 2015, the U.S. Department of Justice notified the court of its decision not to intervene in the case, and the court thereafter approved a case management plan imposing certain deadlines. The plaintiff-relators filed a Second Amended Complaint in October 2015, and defendants filed a Motion to Dismiss such Complaint in December 2015. The Company intends to fully cooperate withvigorously defend this governmental investigationaction, but at this time the Company is unable to predict the timing and is involved in ongoing discussions with the government regardingoutcome of this matter.

        On July 13, 2015, the federal District Court for the Eastern District of Tennessee unsealed a qui tam Complaint in Armes v. Garman, et al, No. 3:14-cv-00172-TAV-CCS, which named as defendants Select, Select Specialty Hospital—Knoxville, Inc. ("SSH-Knoxville"), Select Specialty Hospital—North Knoxville, Inc. and ten current or former employees of these facilities. The Complaint was unsealed after the United States and the State of Tennessee notified the Court on July 13, 2015 that each had decided not to intervene in the case. The Complaint is a civil action that was filed under seal on April 29, 2014 by a respiratory therapist formerly employed at SSH-Knoxville. The Complaint alleges violations of the federal False Claims Act and the Tennessee Medicaid False Claims Act based on extending patient stays to increase reimbursement and to increase average length of stay; artificially prolonging the lives of patients to increase Medicare reimbursements and decrease inspections; admitting patients who do not require medically necessary care; performing unnecessary procedures and services; and delaying performance of procedures to increase billing. The Complaint was served on some of the defendants during October 2015. The defendants filed a Motion to Dismiss such Complaint in November 2015. The Company intends to vigorously defend this action if the relators pursue it, but at this time the Company is unable to predict the timing and outcome of this matter.
