PART 1

Item 1. Business

Overview

We are a leading healthcare services company with a differentiated outpatient delivery model focused on providing high quality, cost effective solutions for U.S. surgical and related ancillary care in support of our patients and physicians. Founded in 2004, as a limited liability company, to own and operate ambulatory surgery centers (“ASCs”), provide anesthesia services, and operate physician practices, we expanded our business in 2011 by acquiring NovaMed, Inc. and in 2014, we acquired Symbion Holdings Corporation (“Symbion”). Further, we completed an initial public offering ("IPO") in October 2015. We are now one of the largest and fastest growing surgical services businesses in the country. We were incorporated in Delaware in 2015 ahead of our initial public offering.

As of December 31, 2016,2017, we owned or operated primarily in partnership with physicians, a portfolio of 104124 surgical facilities in the United States comprised of 99106 ASCs and five18 surgical hospitals (“surgical hospitals,” and together with ASCs referred to as “surgical facilities” or “facilities”) across 2932 states and we owned a majority interest in 7484 of these facilities. Additionally, approximately 73%77% of these facilities were multi-specialty focused. During 2016, over 4,0002017, our physicians provided services to over 600,000 patients in our surgical facilities generating $1.0$1.2 billion in revenue.

Our Growth Strategies

Our differentiated operating model employs a multifaceted strategy to grow revenue, earnings and cash flow. We believe the following are key components to this strategy:

Operations

We operate in three lines of businessreporting segments throughout the United States: surgical facility services, ancillary services and optical services.

As of December 31, 2016,2017, we owned (primarily with physician investors or healthcare systems) or operated 104124 surgical facilities in the United States, including five18 that are licensed as hospitals. For further information regarding our surgical facilities, see Item 2. "Properties" of this report.

Our surgical facility services segment contributed approximately 93%, 91% and 92% of our total revenue for the years ended December 31, 2017, 2016 and 2015, respectively. Our typical ASC is a free-standing facility for planned surgical procedures performed on an outpatient basis on patients not requiring hospitalization and for whom an overnight stay is not expected after surgery. Each center typically has one to four operating or procedure rooms with areas for reception, pre-operative care, recovery and administration. The average facility size is 8,000 to 12,000 square feet. Centers are specifically tailored to meet the needs of physician-partners and their specialties. Of our 99 ASCs, 97 utilize leased real property. We expect to be able to renew or replace a substantial majority of these leases on substantially similar terms. The staff of our ASCs generally includes a center administrator, registered nurses, operating room technicians, as well as other administrative staff.

Our surgical hospitals are generally larger than our ASCs and include inpatient hospital rooms and, in two cases, a limited scope emergency department. Our surgical hospitals also provide ancillary services such as diagnostic imaging, pharmacy, laboratory, obstetrics, physical therapy, oncology and wound care.

We operate both multi-specialty and single-specialty facilities. In multi-specialty facilities, a variety of surgical procedures are performed, including: GI, general surgery, ophthalmology, orthopedics and pain management. We have diversified our facility procedure mix by strategically introducing select specialties that will complement existing facilities. In many cases, we keep certain facilities as single-specialty where it suits an individual facility or market demand.

We own and operate our surgical facilities through partnerships or limited liability companies with physicians, physician groups and healthcare systems. One of our wholly owned subsidiaries typically serves as the general partner or managing member of our surgical facilities.  We generally seek to own a majority interest in our surgical facilities, or otherwise have sufficient control over the facilities to be able to consolidate the financial results of operations of the facilities with ours. In some instances, we will acquire ownership in a surgical facility with the prior owners retaining ownership, and, in some cases, we offer new ownership to other physicians or healthcare systems. We hold majority ownership in 7484 of the 104124 surgical facilities in which we own an interest. We provide intercompany loans to our consolidated facilities which often are secured by a pledge of assets of the partnership or limited liability company. We also have a management agreement with the majority of our surgical facilities, under which we provide day-to-day management services for a management fee, which is typically equal to a percentage of the revenues of the facility.

When attractive opportunities arise, we may develop, acquire or operate surgical facilities through strategic relationships with payors, healthcare systems, payors and other healthcare providers. We believe that forming a relationship with a healthcare system can enhance our ability to attract physicians and access managed care contracts for our surgical facilities in that market. 

The strategic relationships through which we own and operate surgical facilities are governed by partnership and operating agreements that are generally comparable to the partnership and operating agreements of the other surgical facilities in which we own an interest. The primary difference between the structure of these strategic relationships and the other surgical facilities in which we hold ownership is that, in these strategic relationships, a healthcare system holds ownership in the surgical facility, in addition to physician investors. For a general description of the terms of our partnership and operating agreements, see “—Operations—Surgical Facility Services Segment—Surgical Facility Ownership Structure.” In each of these strategic relationships, we also have entered into a management agreement under which we provide day-to-day management services for a management fee equal to a percentage of the revenues of the surgical facility. The terms of those management agreements are comparable to the terms of our management agreements with other surgical facilities in which we own an interest.

We are dependent upon private and government third-party sources of payment for the surgical services we provide. The amounts that our surgical facilities receive in payment for their services may be adversely affected by market and cost factors as well as other factors over which we have no control, including Medicare, Medicaid and state regulations as well as cost containment and utilization decisions and reduced reimbursement schedules of third-party payors. Approximately 38%, 40% and 38% of our patient service revenues were from government sources, mostly Medicare, for the years ended December 31, 2017, 2016 we have relationships with eight healthcare systems relating to 12 ASC's. These healthcare systems include:and 2015, respectively.

We receive reimbursement from Medicare for surgical services based on three different payment systems depending on the site of service: hospital outpatient surgical services, hospital inpatient surgical services and outpatient surgical services provided in exchangeour ASCs.

Surgical services that are provided in hospital outpatient departments (“HOPDs”) are generally reimbursed by Medicare on the Outpatient Prospective Payment System (the “OPPS”). The OPPS is a system established by the Secretary of the Department of Health and Human Services (“HHS”) that determines payment amounts prospectively for various categories of medical services performed in HOPDs. On November 13, 2017, the Centers for Medicare and Medicaid Services ("CMS") published its OPPS final rule for CY 2018. The final rule provides for a management feepayment rate increase of 1.35%. Hospitals that do not meet the reporting requirements of the Medicare Hospital Outpatient Quality Reporting Program will be subject to an additional 2.0% payment rate decrease.

Payments under the Medicare program to ASCs are also made based on the OPPS. However, the payment received from the Medicare program by an ASC is a percentage of the revenuespayment to HOPDs. Reimbursement rates for ASCs are updated annually based on changes in the consumer price index offset by multifactor productivity adjustments. Based on the OPPS Final Rule, ASC reimbursement rates have increased by an additional 1.2% for 2018. CMS has established the Ambulatory Surgical Center Quality Reporting (“ASCQR”) Program as a pay-for-reporting, quality data program. Our ASCs that participate in the ASCQR Program receive the full annual update to the ASC payment rate. Those ASCs that do not successfully report quality data under the ASCQR Program may receive a payment reduction

Hospitals participating in the Medicare and some Medicaid programs, whether paid on a reasonable cost basis or under a prospective payment system, are required to meet certain financial reporting requirements. Federal and, where applicable, state regulations require submission of annual cost reports identifying medical costs and expenses associated with the services provided by each hospital to Medicare beneficiaries and Medicaid recipients. Annual cost reports required under the Medicare and some Medicaid programs are subject to routine governmental audits. These audits may result in adjustments to the amounts ultimately determined to be payable to us under these reimbursement programs. Finalization of these surgical facilities.  The management agreements terminateaudits often takes several years. Providers may appeal any final determination made in 2019 and mayconnection with an

audit. While ASCs are not currently subject to federal cost reporting requirements, it is possible that such requirements, which could be terminated earliercostly for us, will be implemented by either party for material breach after notice and an opportunity to cure.CMS in the future.

Ancillary Services Segment

Our portfolio of outpatient surgical facilities is complemented by our suite of ancillary services, which supportsupports our physicians in providing high quality and cost-efficient patient care. Rather than contracting with third-party providers, in some geographies we own ancillary businesses including a diagnostic laboratory, multi-specialty physician practices, urgent care facilities, anesthesia services and specialty pharmacyanesthesia services. Our Company, physicians and patients benefit from these services through improved clinical efficiency and scheduling, and from incremental revenue and profitability associated with retaining these fees. Our ancillary services segment contributed approximately 6%, 8% and 6% of our total revenue for the years ended December 31, 2017, 2016 and 2015, respectively.

Optical Services Segment

Our wholly-owned optometric practice, Family Vision Care, provides full spectrum vision careoptical services segment contributed approximately 1%, 1% and 2% of our total revenue for the years ended December 31, 2017, 2016 and 2015, respectively.

Our ancillary services revenue primarily consists of fee for service revenue that is derived principally from the provision of physician and laboratory services to patients including eye examsof our surgical facilities. Medicare pays for physician services based upon the MPFS. Payment rates under the MPFS are determined based on (i) relative value units for the services provided, (ii) a geographic adjustment factor and vision testing,(iii) a conversion factor. Payment rates under the MPFS are updated annually by HHS. The primary element in each year’s update calculation is the Medicare Economic Index (“MEI”), which is a measure of the inflation of the cost of operating a physician practice. The update is then adjusted in conformity with the Medicare Access and offers an extensive collectionCHIP Reauthorization Act of prescription eye wear. We provide operations oversight2015 (“MACRA”), which was enacted in April 2015. MACRA established a fixed 0.5% annual adjustment through ongoing management, finance, productcalendar year 2018. Beginning in 2019, Medicare compensation to physicians and marketing support. We sharephysician practices will be subject to adjustment under the Merit-Based Incentive Payment System (“MIPS”). Under MIPS, physicians will be assigned a composite performance score based on measures of quality, resource use, meaningful use of electronic health records, and clinical practice improvement activities. A threshold performance score will be set annually by CMS at the mean or median of all composite scores for a prior annual performance period. Performance exceeding the threshold will result in a positive adjustment, performance below the primary goalthreshold will result in a negative adjustment, and performance at the threshold will result in no adjustment. Physicians who participate in certain alternative payment models, such as accountable care organizations, will be guaranteed a positive payment adjustment under MACRA. The effect of ensuring the highest levelpayment methodology changes under MACRA on our physician practices cannot be predicted.

Certain of patient care while maintaining costsour laboratory ancillary services are reimbursed by Medicare under the Medicare Clinical Laboratory Fee Schedule (“CLFS”). Under a June 23, 2016 final rule that implements the Protecting Access to Medicare Act of 2014 (“PAMA”), as of January 1, 2018 the CLFS payment methodology was adjusted so that payment amounts for laboratory tests on the CLFS is determined by calculating a weighted median of private payor rates using reported private payor rates and growing practice revenue and income.associated volume (number of tests). For tests that were

paid on the CLFS prior to the ophthalmic industry. Member laboratories are provided with a forum forimplementation of PAMA, any reduction in payment amount will be phased in over the exchangefirst 6 years of information and ideas; this is accomplished through supplier sponsored sales promotions, networking opportunities withinpayment under the group, and an annual educational conference. With the combined purchasing power of the group, members receive cost savings from Optical Synergies suppliers, thus increasing their competitiveness in the marketplace.

Acquisitions and Developments

In the last five years we have also completed acquisitionsthe acquisition of NovaMed, Inc. and Symbion, both of which materially expanded our network of existing facilities and ancillary services.

Marketing

We primarily direct our sales and marketing efforts at physicians who would utilize our surgical facilities. Marketing activities directed at physicians and other healthcare providers are coordinated locally by the individual surgical facility and are supplemented by dedicated corporate personnel. These activities generally emphasize the benefits offered by our surgical facilities compared to other facilities in the market, such as the proximity of our surgical facilities to physicians’ offices, the ability to schedule consecutive cases without preemption by inpatient or emergency procedures, the efficient turnaround time between cases, our advanced surgical equipment and our simplified administrative procedures. Although the facility administrator is the primary point of contact, physicians who utilize our surgical facilities are important sources of recommendations to other physicians regarding the benefits of using our surgical facilities. Recruiting teams develop a target list of physicians, and we continually review our progress in successfully recruiting additional local physicians.

We also market our surgical facilities directly to payors, such as health maintenance organizations ("HMOs"), preferred provider organizations ("PPOs"), and other managed care organizations and employers. Payor marketing activities conducted by our corporate office management and facility administrators emphasize the high quality of care, cost advantages and convenience of our surgical facilities, and are focused on making each surgical facility an approved provider under local managed care plans.

Competition

In each market in which we operate a surgical facility, we compete with hospitals and operators of other surgical facilities to attract physicians and patients. We believe that the competitive factors that affect our surgical facilities’ ability to compete for physicians are convenience of location of the surgical facilities, access to capital and participation in managed care programs. In addition, we believe the national prominence, scale and reputation of our company are instrumental in attracting physicians. We believe that our surgical facilities attract patients based upon our quality of care, the specialties and reputations of the physicians who operate in our surgical facilities, participation in managed care programs, ease of access and convenient scheduling and registration procedures.

In developing or acquiring existing surgical facilities, we compete with other public and private surgical facility and hospital companies.  Several large national companies own and/or manage surgical facilities, in some cases in connection with other lines of business with which we do not compete, including HCA  Holdings, Inc., Surgical Care Affiliates, Inc., Envision Healthcare Corporation and Tenet Healthcare Corporation. We also face competition from local hospitals, physicians and other providers who may compete with us in the ownership and operation of surgical facilities, as well as the trend of physicians choosing to perform procedures in an office-based setting rather than in a surgical facility.

Seasonality

Our net revenue fluctuates based on the number of business days in each calendar quarter, because the majority of services provided by physicians in our surgical facilities consist of scheduled procedures and office visits that occur during business hours. RevenueIn addition, revenue in the fourth quarter could also be impacted by an increased utilization of services due to annual deductibles which are not usually met until later in the year and also as patients utilize their healthcare benefits before they expire at year-end.

At December 31, 2016,2017, we had approximately 6,00010,600 employees, including approximately 4,0007,300 full-time employees. None of our employees are represented by a collective bargaining agreement. We believe that we have a good relationship with our employees.

Environmental

We are subject to various federal, state and local laws and regulations relating to the protection of the environment and human health and safety, including those governing the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites and the maintenance of a safe workplace. Our operations include the use, generation and disposal of hazardous materials. We may, in the future, incur liability under environmental statutes and regulations with respect to contamination of sites we own or operate (including contamination caused by prior owners or operators of such sites, adjoining properties or other persons) and the off-site disposal of hazardous substances. We believe that we have been and are in substantial compliance with the terms of all applicable environmental laws and regulations and that we have no liabilities under environmental requirements that we would expect to have a material adverse effect on our business, results of operations or financial condition (including our capital expenditures, earnings and competitive position).

Insurance

We maintain liability insurance in amounts that we believe are appropriate for our operations. Currently, we maintain professional liability insurance that provides coverage on a claims-made basis of $1.0 million per occurrence with a retention of $100,000 per occurrence and $3.0 million in annual aggregate coverage per surgical facility, including the facility and employed staff. We maintain general liability insurance that provides coverage on an occurrence basis of $1.0 million per occurrence with a retention of $25,000 per occurrence and $3.0 million in annual aggregate coverage per surgical facility. We also maintain business interruption insurance and property damage insurance. Coverage under certain of these policies is contingent upon the policy being in effect when a claim is made regardless of when the events which caused the claim occurred. The cost and availability of such coverage has varied widely in recent years. 

In addition, physicians who provide professional services in our surgical facilities are required to maintain separate malpractice coverage with similar minimum coverage limits. While we believe that our insurance policies are adequate in amount and coverage for our anticipated operations, we cannot assure you that the insurance coverage is sufficient to cover all future claims or will continue to be available in adequate amounts or at a reasonable cost.

Most third-party payors reimburse us for surgical and ancillary services pursuant to a written contract.contracts. These contracts generally require that we offer discounts from our established charges. Some of our payments come from third-party payors with which we do not have written contracts. In those situations, commonly known as “out-of-network” services, we generally charge the patients the same co-payment or other patient responsibility amounts that we would have charged had we had a contract with the third-party payor. We also submit a claim for the services to the third-party payor along with full disclosure that we have charged the patient an in-network patient responsibility amount.

Governmental Regulation

Capital expenditures for the construction of new healthcare facilities, the addition of beds or new healthcare services or the acquisition of existing healthcare facilities may be reviewable by state regulators under statutory schemes that are sometimes referred to as certificate of need laws. States with certificate of need laws place limits on the construction and acquisition of healthcare facilities and the expansion of existing facilities and services. In these states, approvals, generally known as certificates of need, are required for capital expenditures exceeding certain preset monetary thresholds for the development, acquisition and/or expansion of certain facilities or services, including, in certain of these states, surgical facilities. We currently operate in 20 states that have a concentration of surgical facilities in certificate of need states as we believe the regulations present a competitive advantage to existing operators.laws.

Our healthcare facilities also are subject to state licensing requirements for medical providers. Our ASC facilitiesASCs have licenses to operate in the states in which they operate and must meet all applicable requirements for ASCs. In addition, even though our surgical facilities that are licensed as hospitals primarily provide surgical services, they must meet all applicable requirements for general hospital licensure. To assure continued compliance with these regulations, governmental and other authorities periodically inspect our surgical facilities. The failure to comply with these regulations could result in the suspension or revocation of a facility’s license. In addition, based on the specific operations

of our surgical facilities, some of these facilities maintain a pharmacy license, a controlled substance registration, a clinical laboratory certification waiver, and environmental protection permits for biohazards and/or radioactive materials, as required by applicable law.

Initiatives to a number of challenges to its constitutionality. On June 28, 2012, the United States Supreme Court upheld challenges to the constitutionality of the “individual mandate” provision, which generally requires all individuals to purchase healthcare insurancerepeal or pay a penalty, but struck down as unconstitutional the provision that would have allowed the federal government to revoke all federal Medicaid funding to any state that did not expand its Medicaid program. As a result, many states have refused to extend Medicaid eligibility to more individuals as envisioned by the law.

CMS has implemented a number of programs that use private contractors that contract with CMS to identify overpayments and underpayments and other potential sources of billing fraud. These contractors, known as Recovery Audit Contractors (“RACs”) and Zone Program Integrity Contractors (“ZPICs”) conduct both post-payment and pre-payment review of claims submitted by Medicare providers. In addition, CMS employs Medicaid Integrity Contractors (“MICs”) to perform post-payment audits of Medicaid claims and identify overpayments. Our facilities and providers continue to receive letters from auditors such as RACs and ZPICs requesting repayment of alleged overpayments for services and incur expenses associated with responding to and appealing these determinations, as well as the costs of repaying any overpayments. Moreover, in recent years, the increase in Medicare payment appeals has created a backlog such that resolving appeals often takes multiple years.

Although all other repayments requested to date as a result of RAC, MIC and ZPIC audits have not been material to our Company, we are unable to quantify the aggregate financial impact of these audits on our facilities given the pending appeals and uncertainty about the extent of future audits.

The majority of our revenue is expected to continue to be received from third-party payors, including federal and state programs, such as Medicare and Medicaid, and commercial payors. To participate in the Medicare program and receive Medicare payment, our surgical facilities must comply with regulations promulgated by the Department of Health and Human Services (“HHS”).HHS. Among other things, these regulations, known as “conditions for coverage” or “conditions of participation,” impose numerous requirements on our facilities, their equipment, their personnel and their standards of medical care, as well as compliance with all applicable state and local laws and regulations. On April 26, 2007, CMS issued a policy memorandum that reaffirmed its prior interpretation of its conditions of participation that all hospitals (other than critical access hospitals) participating in the Medicare program are required to provide basic emergency care interventions regardless of whether or not the hospital maintains an emergency department. Our five facilities licensed as hospitals are required to meet this requirement to maintain their participating provider status in the Medicare program. As of December 31, 2016, two2017, seven of our hospitals, which do not have an emergency room, maintain a protocol for the transfer of patients requiring emergency treatment, which protocol maytreatment. While we believe such protocols satisfy CMS requirements, CMS could interpret such protocols to be interpreted as inconsistent with the 2007 CMS policy memorandum.memorandum, which could jeopardize each facility's participation in the Medicare program. Our surgical facilities must also satisfy the conditions of participation to be eligible to participate in the various state Medicaid programs. The requirements for certification under Medicare and Medicaid are subject to change and, in order to remain qualified for these programs, we may have to make changes from time to time in our facilities, equipment, personnel or services. Although we intend to continue to participate in these reimbursement programs, we cannot assure you that our surgical facilities will continue to qualify for participation.

The Affordable Care Act and its implementing regulations require a hospital to provide written disclosure of physician ownership interests to the hospital’s patients and on the hospital’s website and in any advertising, along with annual reports to the government detailing such interests. Additionally, hospitals that do not have 24/7 physician coverage are required to inform patients of this fact and receive signed acknowledgment from the patients of the disclosure. A hospital’s provider agreement may be terminated if it fails to provide the required notices. In 2010, CMS issued a “self-referral disclosure protocol” for hospitals and other providers that wish to self-disclose potential violations

Federal law contains numerous provisions designed to ensure that services rendered by hospitals to Medicare and Medicaid patients meet professionally recognized standards and are medically necessary and that claims for reimbursement are properly filed. These provisions include a requirement that a sampling of admissions of Medicare and Medicaid patients must be reviewed by quality improvement organizations, which review the appropriateness of Medicare and Medicaid patient admissions and discharges, the quality of care provided, the validity of MS-DRG classifications and the appropriateness of cases of extraordinary length of stay or cost. Quality improvement organizations may deny payment for services provided or assess fines and also have the authority to recommend to HHS that a provider which is in substantial noncompliance with the standards of the quality improvement organization be excluded from participation in the Medicare program. Utilization review is also a requirement of most non-governmental managed care organizations.

The Social Security Act includes provisions addressing false statements, illegal remuneration and other instances of fraud and abuse in federal health care programs. These provisions include the statute commonly known as the federal Anti-Kickback statute (the “Anti-Kickback Statute”). The Anti-Kickback Statute prohibits providers and others from, among other things, soliciting, receiving, offering or paying, directly or indirectly, any remuneration in return for either making a referral for, or ordering or arranging for, or recommending the order of, any item or service covered by a federal healthcare program, including, but not limited to, the Medicare and Medicaid programs. Violations of the Anti-Kickback Statute are criminal offenses punishable by imprisonment and fines of up to $25,000 for each violation. Civil violations are punishable by fines of up to $50,000 for each violation, as well as damages of up to three times the total amount of remuneration received from the government for healthcare claims.

Because physician-investors in our surgical facilities are in a position to generate referrals to the facilities, the distribution of available cash to those investors could come under scrutiny under the Anti-Kickback Statute. Some courts have held that the Anti-Kickback Statute is violated if one purpose (as opposed to a primary or the sole purpose) of a payment to a provider is to induce referrals. Further, Section 6402(f)(2) of the Affordable Care Act amends the Anti-Kickback Statute by adding a provision to clarify that a person need not have actual knowledge of such section or specific intent to commit a violation of the Anti-Kickback Statute. Because none of these cases involved a joint venture such as those owning and operating our surgical facilities, it is not clear how a court would apply these holdings to our activities. It is clear, however, that a physician’s investment income from a surgical facility may not vary with the number of his or her referrals to the surgical facility, and we believe that we comply with this prohibition.facility.

Under regulations issued by the OIG,Office of the Inspector General of the U.S. Department of Health and Human Services (the "OIG"), certain categories of activities are deemed not to violate the Anti-Kickback Statute (commonly referred to as the safe harbors). According to the preamble to these safe harbor regulations, the failure of a particular business arrangement to

We believe the ownership and operations of our surgery centers and hospitals do not fit wholly within any of the safe harbors, but we attempt to structure our ASCs to fit as closely as possible within the safe harbor designed to protect distributions to physician-investors in ASCs who directly refer patients to the ASC and personally perform the procedures at the center as an extension of their practice (the “ASC Safe Harbor”). The ASC Safe Harbor protects four categories of investors, including ASCs owned by (1) general surgeons, (2) single-specialty physicians, (3) multi-specialty physicians and (4) hospital/physician joint ventures, provided that certain requirements are satisfied. These requirements include the following:

We believe that the ownership and operations of our surgical centers will not fully satisfy thisthe ASC Safe Harbor requirements for investment interests in ASCs because, among other things, we or one of our subsidiaries will generally be an investor in and provide management services to each ASC. WeWhile we believe our ASCs would nonetheless be found to be compliant with the Anti-Kickback Statute, we cannot assure you that the OIG would view our activities favorably even though we strive to achieve compliance with the remaining elements of this safe harbor.

In addition, although we expect each physician-investor to utilize ourthe ASCs as an extension of his or her practice and ask each physician-investor to certify this practice, we cannot assure you that all physician-investors will derive at least one-third of their medical practice income from performing Medicare-covered ASC procedures, perform one-third of their procedures at the centers or inform their referred patients of their investment interests. Interests in our ASC joint venture ASCsventures are purchased at what we believe to be fair market value. Investors who purchase at a later time generally pay more for a given percentage interest than founding investors. The result is that while all investors are paid distributions in accordance with their ownership interests, for ASCs where there are later purchases, we cannot meet the safe harbor requirement that return on investment is directly proportional to the amount of capital investment. The OIG has on several occasions reviewed investments relating to ASCs, and in Advisory Opinion No. 07-05, raised concerns that (a) purchases of interests from physicians might yield gains on investment rather than capital infusion to the ASCs, (b) such purchases could be meant to reward or influence the selling physicians’ referrals to the ASC or the hospital, and (c) such returns might not be directly proportional to the amount of capital invested. Nonetheless, we believe our fair market value purchase requirements and distribution policies comply with the Anti-Kickback Statute.

In OIG Advisory Opinion No. 09-09 (July 29, 2009), the OIG concluded that an arrangement involving an ASC joint venture between a hospital and physicians involving the combination of their two ASCs into a single, larger centerASC presented minimal risk of fraud or abuse, despite the fact that it did not fit within any applicable Anti-Kickback safe harbors. Additionally, the OIG stated that fair market value should

Our hospital investments do not fit wholly within the safe harbor for investments in small entities because more than 40.0% of the investment interests are held by investors who are either in a position to refer to the hospital or who provide services to the hospital and more than 40.0% of the hospital’s gross revenue last year were derived from referrals generated by investors. However, we believe we comply with the remaining elements of the safe harbor.

In addition to the physician ownership in our surgical facilities, other financial relationships of ours with potential referral sources could potentially be scrutinized under the Anti-Kickback Statute. We have entered into management agreements to manage the majority of our surgical facilities.facilities and physician practices. Most of these agreements call for our subsidiary to be paid a percentage-based management fee. Although there is a safe harbor for personal services and management contracts (the “Personal Services and Management Safe Harbor”), the Personal Services and Management Safe Harbor requires, among other things, that the amount of the aggregate compensation paid to the manager over the term of the agreement be set in advance. Because our management fees are generally based on a percentage of revenue, our management agreements do not typically meet this requirement. We do, however, believe that our management arrangements satisfy the other requirements of the Personal Services and Management Safe Harbor for personal services and management contracts. The OIG has taken the position in several advisory opinions that percentage-based management agreements are not protected by a safe harbor, and consequently, may violate the Anti-Kickback Statute. We have implemented formal compliance programs designed to safeguard against overbilling and believe that our management agreements comply with the requirements of the Anti-Kickback Statute. However, we cannot assure you that the OIG would find our compliance programs to be adequate or that our management agreements would be found to comply with the Anti-Kickback Statute.

Certain of our ASCs have entered into arrangements for professional services, including arrangements for anesthesia services. In a Special Advisory Bulletin issued in April 2003, the OIG focused on “questionable” contractual arrangements where a health care provider in one line of business (the “Owner”) expands into a related health care business by contracting with an existing provider of a related item or service (the “Manager/Supplier”) to provide the new item or service to the Owner’s existing patient population, including federal health care program patients (so called “suspect Contractual Joint Ventures”). The Manager/Supplier not only manages the new line of business, but may also supply it with inventory, employees, space, billing, and other services. In other words, the Owner contracts out substantially the entire operation of the related line of business to the Manager/Supplier-otherwise a potential competitor-receiving in return the profits of the business as remuneration for its referrals. Through an Advisory Opinion, the OIG extended this suspect contractual joint venture analysis to arrangements between anesthesiologists and physician owners of ASCs. In Advisory Opinion 12-06, the OIG concluded that certain proposed arrangements between anesthesia groups and physician-owned ASCs could result in prohibited remuneration under the federal Anti-Kickback Statute. We believe our arrangements for anesthesia services are distinguishable from those described in Advisory Opinion 12-06 (May 25, 2012) and are in compliance with the requirements of the federal Anti-Kickback Statute. However, we cannot assure you that regulatory authorities would agree with that position.

We also may guarantee a surgical facility’s third-party debt financing and certain lease obligations as part of our obligations under a management agreement. Physician investors are generally not required to enter into similar guarantees. The OIG might take the position that the failure of the physician investors to enter into similar guarantees represents a special benefit to the physician investors given to induce patient referrals and that such failure constitutes a violation of the Anti-Kickback Statute. We believe that the management fees (and in some cases guarantee fees) are adequate compensation to us for the credit risk associated with the guarantees and that the failure of the physician investors to enter into similar guarantees does not create a material risk of violating the Anti-Kickback Statute. However, the OIG has not issued any guidance in this regard.

The OIG is authorized to issue advisory opinions regarding the interpretation and applicability of the Anti-Kickback Statute, including whether an activity constitutes grounds for the imposition of civil or criminal sanctions. We have not, however, sought such an opinion regarding any of our arrangements. If it were determined that our activities, or those of our surgical facilities or hospitals, violate the Anti-Kickback Statute, we, our subsidiaries, our officers, our directors and each surgical facility and hospital investor could be subject, individually, to substantial monetary liability, prison sentences and/or exclusion from participation in any healthcare program funded in whole or in part by the U.S. government, including Medicare, Medicaid, TRICARE or state healthcare programs.

Evolving interpretations of current, or the adoption of new, federal or state laws or regulations could affect many of our arrangements. Law enforcement authorities, including the OIG, the courts and Congress, are increasing their scrutiny of arrangements between healthcare providers and potential referral sources to ensure that the arrangements are not designed as a mechanism to exchange remuneration for patient care referrals or opportunities. Investigators have also demonstrated a willingness to look behind the formalities of a business transaction to determine the underlying purposes of payments between healthcare providers and potential referral sources.

Congress has enacted theThe federal physician self-referral law, or Stark Law, that prohibits certain self-referrals for healthcare services. As currently enacted, theThe Stark Law prohibits a practitioner, including a physician, dentist or podiatrist, from referring patients to an entity with which the practitioner or a member of his or her immediate family has a “financial relationship” for the provision of certain “designated

Notably, "designated health services” is defined to include:

Five of our facilities are licensed as hospitals as of December 31, 2016. The Stark Law currently includes the Whole Hospital Exception, which applies to physician ownership of a hospital, provided such ownership is in the whole hospital and the physician is authorized to perform services at the hospital. We believe that physician investments in our facilities licensed as hospitals meet this requirement. However, certain changes to the Whole Hospital Exception have been the subject of recent regulatory action and legislation. Changes inwere made by the Affordable Care Act include:including:

The Affordable Care Act also requires that each hospital with physician ownership submit an annual report of ownership and/or investment interest. Our hospitals have submitted their first reports. CMS has delayed the collection of the second report and publication of the first annual report. We cannot predict whether other proposed amendments to the Whole Hospital Exception will be included in any future legislation, including a repeal of the Affordable Care Act, or if Congress will adopt any similar provisions that would prohibit or otherwise restrict physicians from holding ownership interests in hospitals. Any such changes could have an adverse effect on our financial condition and results of operations.

In 2010, CMS issued a “self-referral disclosure protocol” for hospitals and other providers that wish to self-disclose potential violations of the Stark Law to CMS and to attempt to resolve those potential violations and any related overpayment liabilities at levels below the maximum penalties and amounts set forth in the statute.

In addition to the physician ownership in our surgical facilities, we have other financial relationships with potential referral sources that potentially could be scrutinized under the Stark Law. We have entered into personal service agreements, such as medical director

The Medicare Patient and Program Protection Act of 1987, as amended by the Health Insurance Portability and Accountability Act of 1996, (“HIPAA”), and the Balanced Budget Act of 1997, impose civil monetary penalties and exclusion from state and federal healthcare programs on providers who commit violations of fraud and abuse laws. HIPAA authorizes the Secretary of the Department of Health & Human Services (“Secretary”), and in some cases requires the Secretary, to exclude individuals and entities that the Secretary determines have “committed an act” in violation of applicable fraud and abuse laws or improperly filed claims in violation of such laws from participating in any federal healthcare program. HIPAA also expanded the Secretary’s authority to exclude a person involved in fraudulent activity from participating in a program providing health benefits, whether directly or indirectly, in whole or in part, by the U.S. government. Additionally, under HIPAA, individuals who hold a direct or indirect ownership or controlling interest in an entity that is found to violate these laws may also be excluded from Medicare and Medicaid and other federal and state healthcare programs if the individual knew or should have known, or acted with deliberate ignorance or reckless disregard of, the truth or falsity of the information of the activity leading to the conviction or exclusion of the entity, or where the individual is an officer or managing employee of such entity. This standard does not require that specific intent to defraud be proven by OIG. Under HIPAA it is also a crime to defraud any commercial healthcare benefit program.

The HIPAA privacy standards apply to individually identifiable information held or disclosed by a covered entity in any form, whether communicated electronically, on paper or orally. These standards impose extensive administrative requirements on us. These standards require our compliance with rules governing the use and disclosure of this health information. They create rights for patients in their health information, such as the right to amend their health information, and they require us to impose these rules, by contract, on any business associate to whom we disclose such information in order to perform functions on our behalf.

The HIPAA security standards require us to establish and maintain reasonable and appropriate administrative, technical and physical safeguards to ensure the integrity, confidentiality and the availability of electronic protected health and related financial information. Although the security standards do not reference or advocate a specific technology, and covered healthcare providers, plans and clearinghouses have the flexibility to choose their own technical solutions, the security standards have required us to implement significant new systems, business procedures and training programs.

Violations of the HIPAA privacy and security regulations may result in civil and criminal penalties. The HITECH Act strengthened the requirements of the HIPAA privacy and security regulations and significantly increased the penalties for violations by introducing a tiered penalty system, with penalties of up to $50,000 per violation with a maximum civil penalty of $1.5 million in a calendar year for violations of the same requirement. However, a single breach incident can result in violations of multiple requirements, resulting in possible penalties well in excess of $1.5 million. Under the HITECH Act, HHS is required to conduct periodic compliance audits of covered entities and their business associates. The HITECH Act and the HIPAA Omnibus Rule also extend the application of certain provisions of the security and privacy regulations to business associates and subjects business associates to civil and criminal penalties for violation of the regulations.

The HITECH Act authorizes State Attorneys General to bring civil actions seeking either an injunction or damages in response to violations of HIPAA privacy and security regulations or the new data breach law that affects the privacy of their state residents. We expect vigorous enforcement of the HITECH Act’s requirements by HHS and State Attorneys General. Additionally, HHS conducted a pilot audit program that concluded December 2012 in the first phase of HHS’ implementation of the HITECH Act’s requirements of periodic audits of covered entities and business associates to ensure their compliance with the HIPAA privacy and security regulations. HHS has allocated increased funding towards HIPAA enforcement activity and such enforcement activity has seen a marked increase over recent years. We cannot predict whether our surgical facilities will be able to comply with the final rules and the financial impact to our surgical facilities in implementing the requirements under the final rules when they take effect, or whether our hospitals will be selected for an audit, or the results of such an audit.

Our facilities also remain subject to any state laws that relate to privacy or the reporting of data breaches that are more restrictive than the regulations issued under HIPAA and the requirements of the HITECH Act. For example, various state laws and regulations may require us to notify affected individuals in the event of a data breach involving certain personal information, such as social security numbers, dates of birth and credit card information.

The HITECH Act includes provisions designed to increase the use of EHR by both physicians and hospitals. Beginning in 2011 and extending through 2016, eligible hospitals may receive incentive payments based upon successfully demonstrating meaningful use of its certified EHR technology. Beginning in 2015, those hospitals that dodid not successfully demonstrate meaningful use of EHR technology arewere subject to reduced payments from Medicare. EHR meaningful use objectives and measures that hospitals and physicians must meet in order to qualify for incentive payments will bewere implemented in three stages. Stage 1 has been in effect since 2011 and Stage 2 took effect for

The HIPAA transaction regulations were issued to encourage electronic commerce in the healthcare industry. These regulations include standards that healthcare providers must follow when electronically transmitting certain healthcare transactions, such as healthcare claims.

Our hospitals are subject to the Emergency Medical Treatment and Active Labor Act (“EMTALA”). This federal law requires any hospital that participates in the Medicare program to conduct an appropriate medical screening examination of every person who presents to the hospital’s emergency department for treatment and, if the patient is suffering from an emergency medical condition, to either stabilize that condition or make an appropriate transfer of the patient to a facility that can handle the condition. The obligation to screen and stabilize emergency medical conditions or transfer exists regardless of a patient’s ability to pay for treatment. Off-campus facilities such as surgery centers that lack emergency departments or otherwise do not treat emergency medical conditions generally are not subject to EMTALA. They must, however, have policies in place that explain how the location should proceed in an emergency situation, such as transferring the patient to the closest hospital with an emergency department. There are severe penalties under EMTALA if a hospital fails to screen or appropriately stabilize or transfer a patient or if the hospital delays appropriate treatment in order to first inquire about the patient’s ability to pay, including civil monetary penalties and exclusion from participation in the government health care programs. In addition, an injured patient, the patient’s family or a medical facility that suffers a financial loss as a direct result of another hospital’s violation of the law can bring a civil suit against that other hospital. CMS has actively enforced EMTALA and has indicated that it will continue to do so in the future. Although weWe believe that our hospitals comply with EMTALA, we cannot predict whether CMS will implement new requirements in the future and, if so, whether our hospitals will comply with any new requirements.EMTALA.

Many of the states in which our surgical facilities operate have adopted statutes and/or regulations that prohibit the payment of kickbacks or any type of remuneration in exchange for patient referrals and that prohibit healthcare providers from, in certain circumstances, referring a patient to a healthcare facility in which the provider has an ownership or investment interest. While these statutes generally mirror the federal Anti-Kickback Statute and Stark Law, they vary widely in their scope and application. Some are specifically limited to healthcare services that are paid for in whole or in part by the Medicaid program; others apply to all healthcare services regardless of payor; and others apply only to state-defined designated services, which may differ from the designated health services under the Stark Law. In addition, many states have adopted statutes that mirror the False Claims Act and that prohibit the filing of a false or fraudulent claim with a state governmental agency. We intend to comply with all applicable state healthcare laws, rules and regulations. However, these laws, rules and regulations have typically been the subject of limited judicial and regulatory interpretation. As a result, we cannot assure you that our surgical facilities will not be investigated or scrutinized by the governmental authorities empowered to do so or, if challenged, that their activities would be found to be lawful. A determination of non-compliance with the applicable state healthcare laws, rules, and regulations could subject our surgical facilities to civil and criminal penalties and could have a material adverse effect on our operations.

We are also subject to various state insurance statutes and regulations that prohibit us from submitting inaccurate, incorrect or misleading claims. Many state insurance laws and regulations are broadly worded and could be implicated, for example, if our surgical facilities were to adjust an out-of-network co-payment or other patient responsibility amounts without fully disclosing the adjustment on the claim submitted to the payor. While some of our surgical facilities adjust the out-of-network costs of patient co-payment and deductible amounts to reflect in-network co-payment costs when providing services to patients whose health insurance is covered by a payor with which the surgical facilities are not contracted, our policy is to fully disclose adjustments in the claims submitted to the payors. We believe that our surgical facilities are in compliance with all applicable state insurance laws and regulations regarding the submission of claims. We cannot assure you, however, that none of our surgical facilities’ insurance claims will ever be challenged. If we were found to be in violation of a state’s insurance laws or regulations, we could be forced to discontinue the violative practice, which could have an adverse effect on our financial position and results of operations, and we could be subject to fines and criminal penalties.

The laws of many states prohibit physicians from splitting fees with non-physicians (i.e., sharing in a percentage of professional fees), prohibit non-physician entities (such as us) from practicing medicine and exercising control over or employing physicians and prohibit referrals to facilities in which physicians have a financial interest. The existence, interpretation and enforcement of these laws vary significantly from state to state. In light of these restrictions, in certain states we facilitate the provision of physician services by maintaining long-term management services agreements through our subsidiaries with affiliated professional contractors, which employ or contract with physicians and other healthcare professionals to provide physician professional services. Under these arrangements, our subsidiaries perform only non-medical administrative services, do not represent that they offer medical services and do not exercise influence or control over the practice of medicine by the physicians employed by the affiliated professional contractors. Although we believe that the fees we receive from affiliated professional contractors have been structured in a manner that is compliant with applicable fee-splitting laws, it is possible that a government regulator could interpret such fee arrangements to be in violation of certain fee-splitting laws. Future interpretations of, or changes in, these laws might require structural and organizational modifications of our existing relationships, and we cannot assure you that

Our clinical laboratories are subject to federal oversight under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”) which extends federal oversight to virtually all clinical laboratories by requiring that they be certified by the federal government or by a federally-approved accreditation agency. CLIA requires that all clinical laboratories meet quality assurance, quality control and personnel standards. Laboratories also must undergo proficiency testing and are subject to inspections. Standards for testing under CLIA are based on the complexity of the tests performed by the laboratory, with tests classified as “high complexity,” “moderate complexity,” or “waived.” Laboratories performing high complexity testing are required to meet more stringent requirements than moderate complexity laboratories. Laboratories performing only waived tests, which are tests determined by the Food and Drug Administration to have a low potential for error and requiring little oversight, may apply for a certificate of waiver exempting them from most of the requirements of CLIA. Our operations also subject to state and local laboratory regulation. CLIA provides that a state may adopt laboratory regulations different from or more stringent than those under federal law, and a number of states have implemented their own laboratory regulatory requirements. State laws may require that laboratory personnel meet certain qualifications, specify certain quality controls, or require maintenance of certain records. We believe that we are in material compliance with all applicable laboratory requirements, but no assurances can be given that our laboratories will pass all future licensure or certification inspections.

It is our policy to conduct our business with integrity and in compliance with the law. We have in place and continue to enhance a company-wide compliance program that focuses on all areas of regulatory compliance including billing, reimbursement, cost reporting practices and contractual arrangements with referral sources.

This regulatory compliance program is intended to help ensure that high standards of conduct are maintained in the operation of our business and that policies and procedures are implemented so that employees act in full compliance with all applicable laws, regulations and company policies. Under the regulatory compliance program, every employee and certain contractors involved in patient care, and coding and billing,

receive initial and periodic legal compliance and ethics training. In addition, we regularly monitor our ongoing compliance efforts and develop and implement policies and procedures designed to foster compliance with the law. The program also includes a mechanism for employees to report, without fear of retaliation, any suspected legal or ethical violations to their supervisors, designated compliance officers in our facilities, our compliance hotline or directly to our corporate compliance office. We believe our compliance program is consistent with standard industry practices. However, we cannot provide any assurances that our compliance program will detect all violations of law or protect against qui tam suits or government enforcement actions.

Item 1A. Risk Factors

Risks Related to Our Business and Industry

We depend on payments from third-party payors, including government healthcare programs and managed care organizations. If these payments are reduced or eliminated, our revenue and profitability could be materially and adversely affected.

We depend upon private and governmental third-party sources of payment for the services provided by physicians in our physician network, to patients in our surgical facilities and by our laboratory and diagnostic services. The amount that we receive in payment for our services may be adversely affected by market and cost factors that we do not control, including Medicare, Medicaid and state regulation changes, cost containment decisions and changes in reimbursement schedules of payors, legislative changes, refinements to the Medicare Ambulatory Surgery Center payment system and refinements made by CMS to Medicare’s reimbursement policies. For instance, cuts to the federal budget caused a 2.0% reduction in Medicare provider payments starting in 2013. Similarly, third-party payors may be successful in negotiating reduced reimbursement schedules with our facilities. Fixed fee schedules, capitation payment arrangements, exclusion from participation in or inability to reach agreements with managed care programs, reduction or elimination of payments or an increase in the payments at a rate that is less than the increase in our costs, or other factors affecting payments for healthcare services over which we have no control could have a material adverse effect on our business, prospects, results of operations and financial condition.

If we are unable to negotiate and enter into favorable contracts or maintain satisfactory relationships and renew existing contracts on favorable terms with managed care organizations or other private third-party payors, our revenue and profitability may decrease.

Payments from private third-party payors, including state workers’ compensation programs and managed care organizations, represented approximately 51%54%, 55%52% and 52%55% of our patient service revenue for the years ended December 31, 2017, 2016 2015 and 2014,2015, respectively. Most of these payments came from third-party payors with which our facilities have contracts. Managed care companies such as HMOs and PPOs, which offer prepaid and discounted medical service packages, represent a growing segment of private third-party payors. If we fail to enter into favorable contracts or maintain satisfactory relationships with managed care organizations, our revenue may decrease. Our competitive position has been, and will continue to be, affected by initiatives undertaken during the past several years by major purchasers of healthcare services, including insurance companies and employers, to revise payment methods and monitor healthcare expenditures in an effort to contain healthcare costs. For instance, managed care payors may lower reimbursement rates in response to increased obligations on payors imposed by the Affordable Care Act or future reductions in Medicare reimbursement rates. Further, managed care payors may narrow their provider networks in response to the need to negotiate lower reimbursement rates with providers. If we are unable to maintain strong relationships with payors, we may not be able to ensure participation in these narrow provider networks. Cost containment measures, such as fixed fee schedules, capitation payment arrangements, reductions in reimbursement schedules by third-party payors and closed provider networks, could also cause a reduction of our revenue in the future.

Some of our payments from third-party payors come from third-party payors with which our surgical facilities, physicians or subsidiaries that provide diagnostic services do not have a contract. In those cases where we provide services to a patient that does not use a third-party payor with which we have contracted, commonly known as “out-of-network” services, we generally charge the patients the same co-payment or other patient responsibility amounts that we would have charged had our surgical facilities had a contract with the payor. In accordance with insurance laws and regulations, we submit a claim for the services to the payor along with full disclosure that our surgical facility has charged the patient an in-network patient responsibility amount. Historically, those third-party payors who do not have contracts with our surgical facilities typically have paid our claims at higher than comparable contracted rates. However, over the past five years we have observed an increase in third-party payors adopting out-of-network fee schedules that are more comparable to our contracted rates or to take other steps to discourage their enrollees from seeking treatment at out-of-network surgical facilities. In these cases, we seek to enter intoWe are not always successful in securing contracts with payors. If the payors.proportion of our services subject to out-of-network fee schedules increases, we may experience a decrease in volume at our ASCs due to fewer referrals of out-of-network patients.

Payments from workers’ compensation payors represented approximately 5% of our patient service revenue for the fiscal year ended December 31, 2016.2017. A majority of states have implemented workers’ compensation provider fee schedules. In some cases, the fee schedule rates contain lower rates than the rates our surgical facilities have historically been paid for the same services. If states reduce the amounts paid to providers under the workers’ compensation fee schedules, it could have a materialan adverse effectimpact on our financial condition and results of operations.operating results.

Significant changes in our payor mix or surgical case mix resulting from fluctuations in the types of cases performed at our facilities could have a material adverse effect on our business, prospects, results of operations and financial condition.

Our results may change from period to period due to fluctuations in payor mix or surgical case mix or other factors relating to the type of cases performed by physicians at our facilities. Payor mix refers to the relative share of total cases provided to patients with no insurance, commercial insurance, Medicare coverage, Medicaid coverage and workers’ compensation insurance, respectively. Since, generally speaking, we receive relatively higher payment rates from commercial and workers’ compensation insurers than Medicare, Medicaid and other

government-funded programs, a significant shift in our payor mix toward a higher percentage of Medicare and Medicaid cases, which could occur for reasons beyond our control, could have an adverse effect on our business, prospects, results of operations and financial condition.

Surgical case mix refers to the relative share of total cases performed by specialty, such as GI, general surgery, ophthalmology, orthopedic and pain management. Generally speaking, certain types of our cases, such as orthopedic cases, generate relatively higher

As we operate in multiple markets, each with a different competitive landscape, shifts within our payor mix or surgical case mix may not be uniform across all of our affiliated facilities. Rather, these shifts may be concentrated within certain markets due to local competitive factors. Therefore, the results of our individual affiliated facilities, including facilities that are material to our results, may be volatile, which could result in a material adverse effect on our business, prospects, results of operations and financial condition.

We have a history of net losses and may not achieve or sustain profitability in the future.

Although we haveWe had a net income in 2016loss attributable to Surgery Partners, Inc. of $53.0 million and 2015had net income of $9.5 million and $1.4 million, respectively, we have historically incurred periods of net losses, including net losses of approximately $65.9 million in 2014, which includes a $21.7 million loss attributable to a one-time transaction cost associated withfor the acquisition of Symbionyears ended December 31, 2017, 2016 and a loss on debt extinguishment of $23.4 million.2015, respectively. We cannot assure you that our revenue will grow or that we will achieve or maintain profitability in the future. Growth of our revenue may slow or revenue may decline and expenses may increase for a number of possible reasons, including reduced demand for our services, regulatory shifts, failure to successfully continue to integrate the operations of Surgery Partners and SymbionNSH and other risks and uncertainties. Even ifthough we have achieved profitability during 2016 and 2015, we may not achieve, sustain or increase profitability on a quarterly or annual basis in the future. Our ability to achieve profitability will be affected by the other risks and uncertainties described in this section and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” All of these factors could contribute to future net losses and, if we are unable to meet these risks and challenges as we encounter them, our business may suffer. If we are not able to achieve, sustain or increase profitability, our business will be adversely affected and our stock price may decline.

We depend on physician utilization of our surgical facilities, which could decrease if we fail to maintain good relationships with affiliated physicians. Our ability to provide medical services at our facilities would be impaired and our revenue reduced if we are not able to maintain these relationships.

Our business depends, among other things, upon the efforts and success of affiliated physicians who provide medical services at our surgical facilities and the strength of our relationships with these physicians. Most physicians are not employees of our surgical facilities and are not contractually required to use our facilities. We generally do not enter into contracts with physicians who use our surgical facilities, other than partnership and operating agreements with physicians who own interests in our surgical facilities, provider agreements with anesthesiology groups that provide anesthesiology services in our surgical facilities, medical director agreements, among others. Physicians who use our surgical facilities also use other facilities or hospitals and may choose to perform procedures in an office-based setting that might otherwise be performed at our surgical facilities. In recent years, pain management and gastrointestinal procedures have been performed increasingly in an office-based setting because of potential cost savings or better access. Although physicians who own interests in our surgical facilities are subject to agreements restricting ownership of competing facilities, these agreements may not restrict procedures performed in a physician office or in other unrelated facilities. Also, these agreements restricting ownership of competing facilities are difficult to enforce, and we may be unsuccessful in preventing physicians who own interests in our surgical facilities from acquiring interests in competing facilities.

The financial success of our facilities is in part dependent upon the volume of procedures performed by the physicians who use our facilities, which is affected by the economy, healthcare reform, increases in patient co-payments and deductibles and other factors outside our or their control. The physicians who use our surgical facilities may choose not to accept patients who pay for services through certain third-party payors, which could reduce our revenue. From time to time, we may have disputes with physicians who use our surgical facilities and/or own interests in our surgical facilities or our Company. Our revenue and profitability could be significantly reduced if we lost our relationship with one or more key physicians or groups of physicians, or if such physicians or groups reduce their use of any of our surgical facilities. In addition, any damage to the reputation of a key physician or group of physicians or the failure of these physicians to provide quality medical care or adhere to professional guidelines at our surgical facilities could damage our reputation, subject us to liability and significantly reduce our revenue.

Physician treatment methodologies and governmental or commercial health insurance controls designed to reduce the number of surgical procedures may reduce our revenue and profitability.

Controls imposed by Medicare and Medicaid, employer-sponsored healthcare plans and commercial health insurance payors designed to reduce surgical volumes, in some instances referred to as “utilization review,” could adversely affect our facilities. Although we are unable to predict the effect these changes will have on our operations, significant limits on the scope of services reimbursed and on reimbursement rates and fees may reduce our revenue and profitability. Additionally, trends in physician treatment protocols and commercial health insurance plan design, such as plans that shift increased costs and accountability for care to patients, could reduce our surgical volumes in favor of lower intensity and lower cost treatment methodologies, each of which could, in turn, have a material adverse effect on our business, prospects, results of operations and financial condition.

Our growth strategy depends in part on our ability to integrate operations of acquired surgical facilities, attract new physician partners, and to acquire and develop additional surgical facilities, on favorable terms. If we are unable to achieve any of these goals, our future growth could be limited and our operating results could be adversely affected.

We believe that an important component of our financial performance and growth is our ability to provide physicians who use our facilities with the opportunity to purchase ownership interests in our facilities. We may not be successful in attracting new physician investment in our surgical facilities, and that failure could result in a reduction in the quality, efficiency and profitability of our facilities. Based on competitive factors and market conditions, physicians may be able to negotiate relatively higher levels of equity ownership in our facilities, consequently limiting or reducing our share of the profits from these facilities. In addition, physician ownership in our facilities is subject to certain regulatory restrictions.

Our acquisition activities, and our limited development activities, require substantial capital resources, and we may need to obtain additional capital or financing, from time to time, to fund these activities. Historically, we have funded acquisition and development activities through our credit facilities. As a result, we may take actions that could have a material adverse effect on our business, prospects, results of operations and financial condition, including incurring substantial debt with certain restrictive terms. Further, sufficient capital or financing may not be available to us on satisfactory terms, if at all. In addition, our ability to acquire and develop additional surgical facilities may be

limited by state certificate of need programs, licensure requirements, antitrust laws, and other regulatory restrictions on expansion. We also face significant competition from local, regional and national health systems and other owners of surgical facilities in pursuing attractive acquisition candidates. The limited number of surgical facilities we develop typically incur losses in their early months of operation (more so in the case of surgical hospitals) and, until their case loads grow, they generally experience lower total revenue and operating margins than established surgical facilities, and we expect this trend to continue.

If we are not successful in integrating newly acquired surgical facilities, we may not realize the potential benefits of such acquisitions. Likewise, if we are not able to integrate acquired facilities’ operations and personnel with ours in a timely and efficient manner, then the potential benefits of the transaction may not be realized. Further, any delays or unexpected costs incurred in connection with integration could have a material adverse effect on our operations and earnings. In particular, if we experience the loss of key personnel or if the effort devoted to the integration of acquired facilities diverts significant management or other resources from other operational activities, our operations could be impaired.

If we acquire or develop additional facilities, we may experience difficulty in retaining or integrating their operations, key physicians, systems and personnel. In some acquisitions, we may have to renegotiate, or risk losing, one or more of the facility’s commercial payor contracts. We may also be unable to immediately collect the accounts receivable of an acquired facility while we align the payors’ payment systems and accounts with our own systems. Certain transactions can require licensure changes which, in turn, result in disruptions in payment for services.

In addition, although we conduct extensive due diligence prior to the acquisition of surgical facilities and seek indemnification from prospective sellers covering unknown or contingent liabilities, we may acquire facilities with unknown or contingent liabilities, including liabilities for failure to comply with healthcare laws and regulations. Although we maintain professional liability insurance that provides coverage on a claims-made basis of $1.0 million per occurrence with a retention of $100,000 per occurrence and $3.0 million in annual aggregate coverage per surgical facility, as well as an additional umbrella liability insurance policy in the aggregate amount of $33.0 million, we do not maintain insurance specifically covering all unknown or contingent liabilities that may have occurred prior to the acquisition of facilities. In some cases, our right to indemnification for these liabilities from the seller may be subject to negotiated limits or limits on our ability to enforce indemnification rights.

Our rapid growth has placed, and will continue to place, increased demands on our management, operational and financial information systems and other resources. Furthermore, expansions into new geographic markets and services may require us to comply with new and unfamiliar legal and regulatory requirements, which could impose substantial obligations on us and our management, cause us to expend additional time and resources, and increase our exposure to penalties or fines for non-compliance with such requirements. To accommodate our past and anticipated future growth, and to compete effectively, we will need to continue to improve our management, operational and financial information systems and to expand, train, manage and motivate our workforce. Our personnel, systems, procedures or controls may not be adequate to support our operations in the future. Further, focusing our financial resources and management attention on the expansion of our operations may negatively impact our financial results. Any failure to improve our management, operational and financial information systems, or to expand, train, manage or motivate our workforce, could reduce or prevent our growth.

Shortages of surgery-related products, equipment and medical supplies and quality control issues with such products, equipment and medical supplies could disrupt our operations and adversely affect our case volume, surgical case mix and profitability.

Our operations depend significantly upon our ability to obtain sufficient surgery-related products, drugs, equipment and medical supplies from suppliers on a timely basis. If we are unable to obtain such necessary products, or if we fail to properly manage existing inventory levels, the surgical facilities may be unable to perform certain surgeries, which could adversely affect case volume or result in a negative shift in surgical case mix. In addition, as a result of shortages, we could suffer, among other things, operational disruptions, disruptions in cash flows, increased costs and reductions in profitability. At times, supply shortages have occurred in our industry, and such shortages may be expected to recur from time to time.

Medical supplies and services can also be subject to supplier product quality control incidents and recalls. In addition to contributing to materials shortages, product quality can affect patient care and safety. Material quality control incidents have occurred in the past and may occur again in the future, for reasons beyond our control, and such incidents can negatively impact case volume, product costs and our reputation. In addition, we may have to incur costs to resolve quality control incidents related to medical supplies and services regardless of whether they were caused by us. Our inability to obtain the necessary amount and quality of surgery-related products, equipment and medical supplies due to a quality control incident or recall could have a material adverse effect on our business, prospects, results of operations and financial condition.

The healthcare business is highly competitive and each of the individual geographic areas in which we operate has a different competitive landscape. In each of our markets we compete with other healthcare providers for patients and in contracting with commercial payors. In addition, because the number of physicians available to utilize and invest in our facilities is finite, we face intense competition from other surgery centers, hospitals, health systems and other healthcare providers in recruiting physicians to utilize and invest in our facilities. We are in competition with other surgery centers, hospitals and healthcare systems in the communities we serve to attract patients and provide them with the care they need.

There are also unaffiliated hospitals in each market in which we operate. These hospitals have established relationships with physicians and payors. In addition, other companies either currently are in the same or similar business of developing, acquiring and operating surgical facilities or may decide to enter our business. Many of these companies have greater resources than we do, including financial, marketing, staff and capital resources. We also may compete with some of these companies for entry into strategic relationships with healthcare systems and healthcare professionals. In addition, many physician groups develop surgical facilities without a corporate partner. In recent years, more physicians are choosing to perform procedures, including pain management and gastrointestinal procedures, in an office-based setting rather than in a surgical facility. If we are unable to compete effectively with any of these entities or groups, we may be unable to implement our business strategies successfully and our financial position and results of operations could be adversely affected.

Competition for physicians and nurses, shortages of qualified personnel or other factors could increase our labor costs and adversely affect our revenue, profitability and cash flows.

Our operations are dependent on the efforts, abilities and experience of our physicians and clinical personnel. We compete with other healthcare providers, primarily hospitals and other surgical facilities, in attracting physicians to utilize our surgical facilities, nurses and medical staff to support our surgical facilities, recruiting and retaining qualified management and support personnel responsible for the daily operations of each of our facilities and in contracting with managed care payors in each of our markets. In some markets, the lack of availability of clinical personnel, such as nurses, has become a significant operating issue facing all healthcare providers. This shortage may require us to continue to enhance wages and benefits to recruit and retain qualified personnel or to contract for more expensive temporary personnel. For the year-ended December 31, 2016,2017, our salary and benefit expenses represented approximately 31% of our revenue. We also depend on the available labor pool of semi-skilled and unskilled workers in each of the markets in which we operate.

If our labor costs increase, we may not be able to raise rates to offset these increased costs. Because a significant percentage of our revenue consistconsists of fixed, prospective payments, our ability to pass along increased labor costs is limited. In particular, if labor costs rise at an annual rate greater than our net annual consumer price index basket update from Medicare, our results of operations and cash flows will likely be adversely affected. Any union activity at our facilities that may occur in the future could contribute to increased labor costs. Certain proposed changes in federal labor laws and the National Labor Relations Board’s modification of its election procedures could increase the likelihood of employee unionization attempts. Although none of our employees are currently represented by a collective bargaining agreement, to the extent a significant portion of our employee base unionizes, it is possible our labor costs could increase materially. Our failure to recruit and retain qualified management and medical personnel, or to control our labor costs, could have a material adverse effect on our business, prospects, results of operations and financial condition.

Some jurisdictions preclude us from entering into non-compete agreements with our physicians, and other non-compete agreements and restrictive covenants applicable to certain physicians and other clinical employees may not be enforceable.

We have contracts with physicians and other health professionals in many states. Some of our physician services contracts, as well as many of our physician services contracts with hospitals, include provisions preventing these physicians and other health professionals from competing with us both during and after the term of our contract with them. The law governing non-compete agreements and other forms of restrictive covenants varies from state to state. Some jurisdictions prohibit us from entering into non-compete agreements with our professional staff. Other states are reluctant to strictly enforce non-compete agreements and restrictive covenants against physicians and other healthcare professionals. Therefore, there can be no assurance that our non-compete agreements related to employed or otherwise contracted physicians and other health professionals will be enforceable if challenged in certain states. In such event, we would be unable to prevent former employed or otherwise contracted physicians and other health professionals from competing with us, potentially resulting in the loss of some of our hospital contracts and other business. Additionally, certain facilities have the right to employ or engage our providers after the termination or expiration of our contract with those facilities and cause us not to enforce our non-compete provisions related to those providers.

We may become involved in litigation which could negatively impact the value of our business.

From time-to-time we are involved in lawsuits, claims, audits and investigations, including those arising out of services provided, personal injury claims, professional liability claims, billing and marketing practices, employment disputes and contractual claims. We may become subject to future lawsuits, claims, audits and investigations that could result in substantial costs and divert our attention and resources and adversely affect our business condition. In addition, since our current growth strategy includes acquisitions, among other things, we may become exposed to legal claims for the activities of an acquired business prior to the acquisition. These lawsuits, claims, audits or investigations, regardless of their merit or outcome, may also adversely affect our reputation and ability to expand our business.

In addition, from time to time we have received, and expect to continue to receive, correspondence from former employees terminated by us who threaten to bring claims against us alleging that we have violated one or more labor and employment regulations. In certain instances former employees have brought claims against us and we expect that we will encounter similar actions against us in the future. An adverse outcome in any such litigation could require us to pay contractual damages, compensatory damages, punitive damages, attorneys’ fees and costs.

In recent years, 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 monetary claims and significant defense costs. We also owe certain defense and indemnity obligations to our officers and directors.

We maintain liability insurance in amounts that we believe are customary for the industry. Currently, we maintain professional liability insurance that provides coverage on a claims-made basis of $1.0 million per occurrence with a retention of $100,000 per occurrence and $3.0 million in annual aggregate coverage per surgical facility, including the facility and employed staff. We maintain general liability insurance that provides coverage on a occurrence basis of $1.0 million per occurrence with a retention of $25,000 per occurrence and $3.0 million in annual aggregate coverage per surgical facility. We also maintain business interruption insurance and property damage insurance, as well as an additional umbrella liability insurance policy in the aggregate amount of $33.0 million. Coverage under certain of these policies is contingent upon the policy being in effect when a claim is made regardless of when the events which caused the claim occurred. In addition, physicians who provide professional services in our surgical facilities are required to maintain separate malpractice coverage with similar minimum coverage limits. We also maintain a directors’ and officers’ insurance policy, which insures our directors and officers against unindemnified losses arising from certain wrongful acts in their capacities as directors and officers and reimburses us for those losses for which we have lawfully indemnified the directors and officers.

This insurance coverage may not cover all claims against us. Insurance coverage may not continue to be available at a cost allowing us to maintain adequate levels of insurance. If one or more successful claims against us were not covered by or exceeded the coverage of our insurance, our financial condition and results of operations could be adversely affected. Our business, profitability and growth prospects could suffer if we face negative publicity or we pay damages or defense costs in connection with a claim that is outside the scope or limits of coverage of any applicable insurance coverage, including claims related to adverse patient events, contractual disputes, professional and general liability, and directors’ and officers’ duties.

In addition, if our costs of insurance and claims increase, then our earnings could decline. Market rates for insurance premiums and deductibles have been steadily increasing. Our earnings and cash flows could be materially and adversely affected by any of the following:

Financial pressures on patients, and current and future economic condition, may adversely affect our volume and surgical case mix.

Even as the U.S. economy shows signs of sustained, if modest, growth, many individuals throughout the country continue to experience difficult financial conditions. Our case volume and surgical case mix may be adversely affected by patients’ unwillingness to pay for procedures in our facilities. Higher numbers of unemployed individuals generally translates into more individuals without healthcare insurance to help pay for procedures, thereby increasing the potential for persons to elect not to have procedures performed. Even procedures normally thought to be non-elective may be delayed or may not be performed if the patient cannot afford the procedure due to a lack of insurance or money to pay their portion of our facilities’ fee. Although we have taken steps to minimize the impact of these conditions, it is difficult to predict the degree to which our business will continue to be impacted by such conditions or the course of the economy in the future.

In addition, the difficult conditions of the U.S. economy have adversely affected and could continue to adversely affect the budgets of individual states and the federal government, which has resulted in and could continue to result in attempts to reduce payments made to us by federal and state government healthcare programs, including Medicare, military services, Medicaid and workers’ compensation programs, a reduction in the scope of services covered by those programs and an increase in taxes and assessments on our activities. Additionally, even though the Supreme Court upheld an IRS rule extending tax credits to individuals purchasing health insurance under the Affordable Care Act through federally established exchanges in its decision in King v. Burwell, there continues to be uncertainty regarding the future implementation of the Affordable Care Act, and any such result could adversely affect our business by exacerbating the financial pressures on patients, leading them to further delay or cancel non-emergency surgical procedures.

Our surgical facilities are sensitive to regulatory, economic and other conditions in the states where they are located. In addition, three of our surgical facilities account for a significant portion of our patient service revenue.

Our revenue areis particularly sensitive to regulatory, economic and other conditions in the states of Florida and Texas. As of December 31, 2016,2017, we owned and operated five9 consolidated surgical facilities in Texas and 23 consolidated surgical facilities in Florida. The Texas facilities represented approximately 10%, 11% and 13%14% of our revenue duringin fiscal 2017 and the years ended December 31, 2016, 2015 and 2014, respectively. The Florida facilities represented approximately 13%, 15% and 14%12% of our revenue during the years ended December 31, 2016, 2015 and 2014, respectively.in fiscal 2017.

In addition, our surgical hospital in Idaho Falls, Idaho represented 20%, 19% and 17% of our revenue during the years ended December 31, 2016, 2015 and 2014, respectively.fiscal 2017. This surgical hospital also provides ancillary services, including physician practices, radiation oncology and anesthesia services. If there were an adverse regulatory, economic or other development in any of the states in which we have a higher concentration of facilities, including Idaho, our case volumes could decline in such states or there could be other unanticipated adverse impacts on our business in those states, which could have a material adverse effect on our business, prospects, results of operations and financial condition.

If any of our existing healthcare facilities lose their accreditation status or any of our new facilities fail to receive accreditation, such facilities could become ineligible to receive reimbursement under Medicare or Medicaid or other third-party payors.

The construction and operation of healthcare facilities are subject to extensive federal, state and local regulation relating to, among other things, the adequacy of medical care, equipment, personnel, operating policies and procedures, fire prevention, rate-setting and compliance with building codes and environmental protection. Additionally, such facilities are subject to periodic inspection by government authorities and accreditation organizations to assure their continued compliance with these various standards.

All of our facilities are deemed certified, meaning that they are accredited, properly licensed under the relevant state laws and regulations and certified under the Medicare program or are in the process of applying for such accreditation, licensing or certification. The effect of maintaining certified facilities is to allow such facilities to participate in the Medicare and Medicaid programs. We believe that all of our facilities are in material compliance with applicable federal, state, local and other relevant accreditation and certification regulations and standards. However, should any of our healthcare facilities lose their deemed certified status and thereby lose certification under the Medicare or Medicaid programs, such facilities would be unable to receive reimbursement from either or both of those programs, and possibly from other third-party payors, and our business could be materially adversely affected.

Certain of our partnership and operating agreements contain provisions giving rights to our partners and other members that may be adverse to our interests.

Certain of the agreements governing the limited partnerships ("LPs"), general partnerships ("GP") and limited liability companies ("LLCs") through which we own and operate our facilities contain provisions that give our partners or other members rights that may, in certain circumstances, be adverse to our interests. These rights include, but are not limited to, rights to purchase our interest in the partnership or LLC, rights to require us to purchase the interests of our partners or other members, or rights requiring the consent of our partners and other members prior to our transferring our ownership interest in a facility or prior to a change in control of us or certain of our subsidiaries. With respect to these purchase rights, the agreements generally include a specified formula or methodology to determine the applicable purchase price, which may or may not reflect fair market value.

Additionally, many of our partnership and operating agreements contain restrictions on actions that we can take, even though we may be the general partner or the managing member. Examples of these restrictions include the rights of our partners and other members to approve the sale of substantially all of the assets of the partnership or LLC, to dissolve the partnership or LLC, to appoint a new or additional general partner or managing member and to amend the partnership or operating agreements. Many of our agreements also restrict our ability in certain instances to compete with our existing facilities or with our partners. Where we hold only a limited partner or a non-managing member interest, the general partner or managing member may take certain actions without our consent, although we typically have certain protective rights to approve major decisions such as the sale of substantially all of the assets of the entity, dissolution of the partnership or LLC and the amendment of the partnership or operating agreement. These management and governance rights held by our partners and other members limit and restrict our ability to make unilateral decisions about the management and operation of the facilities without the approval of our partners and other members.

We may have a special legal responsibility to the holders of ownership interests in the entities through which we own our facilities, which may conflict with, and prevent us from acting solely in, our own best interests or the interests of our stockholders.

We generally hold our ownership interests in facilities through limited or general partnerships, LLCs or limited liability partnerships (“LLPs”) in which we maintain an ownership interest along with physicians and, in some cases, physicians and health systems. As general partner and manager of most of these entities, we may have a special responsibility, known as a fiduciary duty, to manage these entities in the best interests of the other owners. We also have a duty to operate our business for the benefit of our stockholders. As a result, we may encounter conflicts between our responsibility to the other owners and our responsibility to our stockholders. For example, we have entered into management agreements to provide management services to our surgical facilities in exchange for a fee. Disputes may arise as to the nature of the services to be provided or the amount of the fee to be paid. In these cases, we may be obligated to exercise reasonable, good faith judgment to resolve the disputes and may not be free to act solely in our own best interests or the stockholders best interest. Disputes may also arise between us and our physician investors with respect to a particular business decision or regarding the interpretation of the provisions of the applicable partnership or limited liability company agreement. We seek to avoid these disputes but have not implemented any measures to resolve these conflicts if they arise. If we are unable to resolve a dispute on terms favorable or satisfactory to us, it could have a material adverse effect on our business, prospects, results of operations and financial condition.

Growth of patient receivables or deterioration in the ability to collect on these accounts, due to changes in economic conditions or otherwise, could have a material adverse effect on our business, prospects, results of operations and financial condition.

The current practice of providing medical services in advance of payment or, in many cases, prior to assessment of ability to pay for such services, may have significant negative impact on our revenue, bad debt expense and cash flow. We bill numerous and varied payors, such as self-pay patients, managed care payors and Medicare and Medicaid. These different payors typically have different billing requirements that must be satisfied prior to receiving payment for services rendered. Reimbursement is typically conditioned on our documenting medical necessity and correctly applying diagnosis codes. Incorrect or incomplete documentation and billing information could result in non-payment for services rendered. The primary collection risks with respect to our patient receivables relate to patient accounts for which the primary third-party payor has paid the amounts covered by the applicable agreement, but patient responsibility amounts (deductibles and co-payments) remain outstanding.

Additional factors that could complicate our billing include:

We provide for bad debts principally based upon the type of payor and the age of the receivables. Our allowance for doubtful accounts at December 31, 2016 and 2015,2017 represented 12% and 9%1% of our accounts receivable balance, respectively.balance. Due to the difficulty in assessing future trends, including the effects of changes in economic conditions, we could be required to increase our provision for doubtful accounts. An increase in the amount of patient receivables or a deterioration in the collectability of these accounts could have a material adverse effect on our business, prospects, results of operations and financial condition.

The loss of certain physicians can have a disproportionate impact on certain of our facilities.

Generally, the top referring physicians within each of our facilities represent a large share of our revenue and admissions. The loss of one or more of these physicians, even if temporary, could cause a material reduction in our revenue, which could take significant time to replace given the difficulty and cost associated with recruiting and retaining physicians.

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

As a result of purchase accounting for our various acquisition transactions, including the NSH Merger, our balance sheet at December 31, 20162017 contained intangible assets designated as either goodwill or intangibles totaling approximately $1.6$3.3 billion in goodwill and approximately $48.0$58.9 million in intangibles. AdditionalAny other additional acquisitions that result in the recognition of additional intangible assets would cause an increase in these intangible assets. On an ongoing basis, we evaluate whether facts and circumstances indicate any impairment of the value of intangible assets. As circumstances change, we cannot assure you that the value of these intangible assets will be realized by us. If we determine that a significant impairment has occurred, we will be required to write-off the impaired portion of intangible assets, which could have a material adverse effect on our results of operations in the period in which the write-off occurs.

As of December 31, 2016,2017, we had U.S. federal net operating loss (“NOL”) carryforwards of approximately $390.6$507.4 million and state NOL carryforwards of approximately $542.7$619.6 million, which may be limited annually due to certain change in ownership provisions of Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). In addition, as a result of the Symbion acquisition, approximately $179 million in NOL carryforwards are subject to an annual Section 382 base limitation of $4.9 million, and, as a result of the Novamed acquisition, approximately $17 million in NOL carryforwards are subject to an annual Section 382 base limitation of $4.9 million. As a result of the NSH acquisition, approximately $20.5 million in NOL carryforwards are subject to an annual Section 382 base limitation of $2.8 million. Further, the sale of H.I.G.'s shares to Bain Capital in connection with the Transactions resulted in an ownership change as defined in Section 382. As a result, we will not be able to use our pre-ownership-change NOLs in excess of the limitation imposed by Section 382. These limitations, when combined with amounts allowable due to net unrecognized built in gains, are not expected to impact the realization of the deferred tax assets associated with these NOLs. Our federal NOL carryforwards will begin to expire in 2025 and will completely expire in 2036,2037, and our state NOL carryforwards will begin to expire in 20172018 and will completely expire in 2036.2037. Future ownership changes may subject our NOL carryforwards to further annual limitations, which could restrict our ability to use them to offset our taxable income in periods following the ownership changes.

We entered into a tax receivable agreement that will require us to paymake payments to the pre-IPO owners of Surgery Center Holdings, LLC (the "Pre-IPO Owners") for certain tax benefits, including for tax benefits attributable to pre-IPO NOLs,, which amounts are expected to be material.

On September 30, 2015, Surgery Partners, Inc. became the direct parent and sole member of Surgery Center Holdings, LLC (the "Reorganization"). We indirectly acquired favorable tax attributes in connection with the Reorganization. These tax attributes would not be available to us in the absence of the consummation of the Reorganization. As part of the Reorganization, we entered into a tax receivable agreement. In connection with the Transactions completed in in August 2017, we entered into an agreement (theto amend the TRA (as amended, the “TRA”) under, which generallybecame effective on August 31, 2017.

Pursuant the TRA, we will be requiredagreed to paymake annual payments to H.I.G. in its capacity as the Pre-IPO Owners 85%stockholders representative on behalf of the cash savings, if any,other pre-Reorganization stockholders pursuant to a fixed payment schedule. The final payment is scheduled to be made in U.S. federal, state or local tax that we actually realize (or are deemed to realize in certain circumstances) as a result of (i) certain tax attributes, including NOLs, capital losses, charitable deductions, alternative minimum tax credit carryforwards and federal and state tax credits of Surgery Center Holdings, Inc. and its affiliates relating to taxable years ending on or before the date of the Reorganization (calculated by assuming the taxable year of the relevant entity closes on the date of the Reorganization) that are or become available to us and our wholly-

Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our financial condition and results of operations.

We are subject to income taxes in the United States, and our domestic tax liabilities are subject to the allocation of expenses in differing jurisdictions. OurOn December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the Code, including:

There are significant uncertainties regarding the interpretation and application of the Tax Act. Additional guidance on the Tax Act is expected; however, the timing, form, scope and content of such guidance is not known. In addition to the changes implemented by the Tax Act and associated regulations and guidance, our future effective tax rates could be subject to volatility or adversely affected by a number of other factors, including:

In addition, we may be subject to audits of our income, sales and other transaction taxes by U.S. federal, state and local authorities. Outcomes from these audits could have an adverse effect on our financial condition and results of operations.

Our facilities may be adversely impacted by weather and other factors beyond our control, and disruptions in our disaster recovery systems or management continuity planning could limit our ability to operate our business effectively.

The financial results of our facilities may be negatively impacted by adverse weather conditions, such as tornadoes, earthquakes and hurricanes, or other factors beyond our control, such as wildfires. These weather conditions or other factors could disrupt patient scheduling, displace our patients, employees and physician partners and force certain of our facilities to close temporarily or for an extended period of time. In certain markets, we have a large concentration of surgery centers that may be simultaneously affected by adverse weather condition or events beyond our control.

While we have disaster recovery systems and business continuity plans in place, any disruptions in our disaster recovery systems or the failure of these systems to operate as expected could, depending on the magnitude of the problem, adversely affect our operating results by limiting our capacity to effectively monitor and control our operations. Despite our implementation of a variety of security measures, our technology systems could be subject to physical or electronic break-ins, and similar disruptions from unauthorized tampering or weather related disruptions where our headquarters is located. In addition, in the event that a significant number of our management personnel were unavailable in the event of a disaster, our ability to effectively conduct business could be adversely affected.

The healthcare industry is heavily regulated and we are subject to many laws and regulations at the federal, state and local government levels in the markets in which we operate. These laws and regulations require that our facilities meet various licensing, accreditation, certification and other requirements, including, but not limited to, those relating to:

If we fail or have failed to comply with applicable laws and regulations, we could subject ourselves to administrative, civil or criminal penalties, cease and desist orders, forfeiture of amounts owed and recoupment of amounts paid to us by governmental or commercial payors, loss of licenses necessary to operate and disqualification from Medicare, Medicaid and other government-sponsored healthcare programs.

Many of these laws and regulations have not been fully interpreted by regulatory authorities or the courts, and their provisions are sometimes open to a variety of interpretations. Different interpretations or enforcement of existing or new laws and regulations could subject our current practices to allegations of impropriety or illegality, or require us to make changes in our operations, facilities, equipment, personnel, services, capital expenditure programs or operating expenses to comply with the evolving rules. Any enforcement action against us, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.

Because of the many variables involved, we are unable to predict the net effect of the Affordable Care Act and other associated changes within the healthcare industry on us or our operations. Depending on how the Affordable Care Act continues to be interpreted, implemented or changed, it could have a material adverse effect on our business, prospects, results of operations and financial condition.

If laws governing the corporate practice of medicine or fee-splitting change, we may be required to restructure some of our relationships, which may result in a significant loss of revenue and divert other resources.

The laws of various states in which we operate or may operate in the future do not permit business corporations to practice medicine, to exercise control over or employ physicians who practice medicine or to engage in various business practices, such as fee-splitting with physicians (i.e., sharing in a percentage of professional fees). The interpretation and enforcement of these laws vary significantly from state to state. We provide management services to a physician network. If our arrangements with this network were deemed to violate state corporate practice of medicine, fee-splitting or similar laws, or if new laws are enacted rendering our arrangements illegal, we may be subject to civil and/or criminal penalties and could be required to restructure or terminate these arrangements, any of which may result in a significant loss of revenue and divert othermanagement and business resources.

If regulations change, we may be obligated to purchase some or all of the ownership of our physician partners or renegotiate some of our partnership and operating agreements with our physician partners and management agreements with surgical facilities.

Upon the occurrence of various fundamental regulatory changes or changes in the interpretation of existing regulations, we may be obligated to purchase all of the ownership of the physician investors in most of the partnerships or limited liability companies that own and operate our surgical facilities. The purchase price that we would be required to pay for the ownership is specified in our partnership agreements and is typically based on either a multiple of the surgical facility’s EBITDA, as defined in our partnership and operating agreements with these surgical facilities, or the fair market value of the ownership as determined by a third-party appraisal. The physician investors in some of our surgical facilities can require us to purchase their interests in exchange for cash or shares of our common stock if these regulatory changes occur. In addition, some of our partnership agreements with our physician partners and management agreements with surgical facilities require us to attempt to renegotiate the agreements upon the occurrence of various fundamental regulatory changes or changes in the interpretation of existing regulations and provide for termination of the agreements if renegotiations are not successful.

Regulatory changes that could create purchase or renegotiation obligations include changes that:

We do not control whether or when any of these regulatory events might occur. In the event we are required to purchase all of the physicians’ ownership, our existing capital resources would not be sufficient for us to meet this obligation. These obligations and the possible termination of our partnership and management agreements would have a material adverse effect on our financial condition and results of operations.

Our revenue will decline if federal or state programs reduce our Medicare or Medicaid payments or if managed care companies reduce reimbursement amounts. In addition, the financial condition of payors and healthcare cost containment initiatives may limit our revenue and profitability.

For the years ended December 31, 2017, 2016 2015 and 2014,2015, we derived approximately 40%38%, 38%40% and 35%38% of our revenue, respectively, from government payors, including Medicare and Medicaid programs. The Medicare and Medicaid programs are subject to statutory and regulatory changes, administrative rulings, interpretations and determinations concerning patient eligibility requirements, funding levels and the method of calculating payments or reimbursements, among other things; requirements for utilization review; and federal and state funding

restrictions, any of which could materially increase or decrease payments from these government programs in the future, as well as affect the timing of payments to our facilities.

We are unable to predict the effect of future government healthcare funding policy changes on our operations. If the rates paid by governmental payors are reduced, if the scope of services covered by governmental payors is limited or if we, or one or moreany of our surgical facilities, are excluded from participation in the Medicare, Medicaid or other government-sponsored healthcare programs, there could be a material adverse effect on our business, financial condition, results of operations or cash flows.

During the past several years, healthcare payors, such as federal and state governments, insurance companies and employers, have undertaken initiatives to revise payment methodologies and monitor healthcare costs. As part of their efforts to contain healthcare costs, payors increasingly are demanding discounted fee structures or the assumption by healthcare providers of all or a portion of the financial risk relating to paying for care provided, often in exchange for exclusive or preferred participation in their benefit plans. We expect efforts to impose greater discounts and more stringent cost controls by government and other payors to continue, thereby reducing the payments we receive for our services.

By way of example, under the Medicare program, physician payments arewere previously updated on an annual basis according to a statutory formula. Because application of the statutory formula for the update factor would have resultedresult in a decrease in total physician payments, for the past several years, Congress has intervenedwould intervene with interim legislation on an annual basis to prevent the reductions. In April 2015, however, the Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, was signed into law, which repealed and replaced the statutory formula for Medicare payment adjustments to physicians. MACRA provides a permanent end to the annual interim legislative updates that had previously been necessary to delay or prevent significant reductions to payments under the Medicare Physician Fee Schedule.MPFS. MACRA extended previous payment rates through June 30, 2015, with a 0.5% update for July 1, 2015 through December 31, 2015, and for each calendar year through 2019, after which there will be a 0% annual update each year through 2025.2018. In addition, MACRA requires the establishment of the Merit-Based Incentive Payment System (“MIPS”),MIPS, beginning in 2019, under which physicians may receive performance-based payment incentives or payment reductions based on their performance with respect to clinical quality, resource use, clinical improvement activities and meaningful use of electronic health records. For more information on the implementation of MACRA, also requires Centers for Medicare & Medicaid Services ("CMS"), beginning in 2019, to provide incentive payments for physicianssee “Business - Sources of Revenue - Ancillary and other eligible professionals that participate in alternative payment models, such as

The amount of our provision for doubtful accounts is based on our assessments of historical collection trends, business and economic conditions, trends in federal and state governmental and private employer health coverage and other collection indicators. A continuation in trends that results in increasing the proportion of accounts receivable being comprised of uninsured accounts and deterioration in the collectability of these accounts could adversely affect our collections of accounts receivable, results of operations and cash flows. As enacted, the Affordable Care Act seeks to decrease, over time, the number of uninsured individuals. Specifically, the Affordable Care Act expands Medicaid eligibility and provides incentives to employers to offer and individuals to purchase health insurance. It is difficult to predict the full impact of the Affordable Care Act due to pending court challenges, legislative threats, implementation uncertainty, and its complexity.

Our surgical facilities do not satisfy the requirements for any of the safe harbors under the federal Anti-Kickback Statute. If a federal or state agency asserts a different position or enacts new laws in this regard, we could be subject to criminal and civil penalties, loss of licenses and exclusion from governmental programs, which may result in a substantial loss of revenue.

The statute commonly known as the federal Anti-Kickback statute (the “Anti-Kickback Statute”) prohibits the offer, payment, solicitation or receipt of any form of remuneration in return for referrals for items or services payable by Medicare, Medicaid, or any other federally funded healthcare program. Additionally, the Anti-Kickback Statute prohibits any form of remuneration in return for purchasing, leasing or ordering, or arranging for or recommending the purchasing, leasing or ordering of items or services payable by Medicare, Medicaid or any other federally funded healthcare program. The Anti-Kickback Statute is very broad in scope and many of its provisions have not been uniformly or definitively interpreted by existing case law or regulations. Moreover, several federal courts have held that the Anti-Kickback Statute can be violated if only one purpose (not necessarily the primary purpose) of a transaction is to induce or reward a referral of business, notwithstanding other legitimate purposes. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Moreover, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act (discussed below). Violations of the Anti-Kickback Statute may result in substantial civil or criminal penalties, including up to five years imprisonment and criminal fines of up to $25,000 and civil penalties of up to $50,000 for each violation, plus three times the remuneration involved or the amount claimed and exclusion from participation in all federally funded healthcare programs. Our exclusion from participation in such programs would have a material adverse effect on our business, prospects, results of operations and financial condition. In addition, many of the states in which we operate have also adopted laws, similar to the Anti-Kickback Statute, that prohibit payments to physicians in exchange for referrals, some of which apply regardless of the source of payment for care. These statutes typically impose criminal and civil penalties, including the loss of a license to do business in the state.

In July 1991, the U.S. Department of Health and Human Services ("HHS"),HHS, issued final regulations defining various “safe harbors” under the Anti-Kickback Statute. Business arrangements that meet the requirements of the safe harbors are not treated as criminal violations under the Anti-Kickback Statute. Business arrangements that do not meet the safe harbor requirements do not necessarily violate the Anti-Kickback Statute, but may be subject to scrutiny by the federal government to determine compliance. Two of the original safe harbors issued in 1991 apply to business arrangements similar to those used in connection with our surgical facilities: the “investment interest”“Investment Interest” safe harbor and the “personal services“Personal Services and management contracts”Management Contracts” safe harbor. However, the structure of the partnerships and limited liability companies operating our surgery centers and surgical hospitals, as well as our various business arrangements involving physician group practices, do not satisfy all of the requirements of either safe harbor. We have entered into management agreements to manage the majority of our surgical facilities. Most of these agreements call for our subsidiary to be paid a percentage-based management fee.  Because our management fees are generally based on a percentage of revenue, our management agreements do not typically meet the Personal Services and Management Contracts safe harbor.  We have implemented formal compliance programs designed to safeguard against overbilling and believe that our management agreements comply with the requirements of the Anti-Kickback Statute. However, we cannot assure you that the OIG would find our compliance programs to be adequate or that our management agreements would be found to comply with the Anti-Kickback Statute.

In November1999, HHS promulgated final regulations creating additional safe harbor provisions, including a safe harbor that applies to physician ownership of or investment interests in surgery centers. The surgery center safe harbor protects four types of investment arrangements: (1) surgeon owned surgery centers; (2) single specialty surgery centers; (3) multi-specialty surgery centers; and (4) hospital/physician surgery centers. Each category has its own requirements with regard to what type of physician may be an investor in the surgery center. In addition to the physician investor, the categories permit an “unrelated” investor, who is a person or entity that is not in a position to provide items or services related to the surgery center or its investors. Our business arrangements with our surgical facilities typically consist of one of our subsidiaries being an investor in each partnership or limited liability company that owns the facility, in addition to providing management and other services to the facility. Therefore, our business arrangements with our surgery centers, surgical hospitals and physician groups do not qualify for “safe harbor”the expanded safe harbor protection from government review or prosecution under the Anti-Kickback Statute, however,Statute. However, we attempt to otherwise structure our surgery centers to fit as closely as possible withinbelieve that we are in compliance with the safe harbor. When a transaction or relationship does not fit within a safe harbor, it does not mean that an Anti-Kickback Statute violation has occurred; rather, it means that the facts and circumstances as well as the intentrequirements of the parties related to a specific transaction or relationship must be examined to determine whether or not any illegal conduct has occurred.Anti-Kickback Statute.

We employ dedicated marketing personnel whose job functions include the recruitment of physicians to perform surgery at our facilities. These employees are paid a base salary plus a productivity bonus. We believe our employment arrangements with these employees are consistent with a safe harbor provision designed to protect payments made to employees. However, a government agency or private party may assert a contrary position.

We also enter into lease agreements with physicians from time to time for the rental of space for our surgical facilities. We seek to structure these lease agreements so that they are in compliance with the Anti-Kickback Statute safe harbor provision regarding real estate leases. However, a government agency or private party may assert a contrary position.

If we fail to comply with physician self-referral laws as they are currently interpreted or may be interpreted in the future, or if other legislative restrictions are issued, we could incur substantial monetary penalties and a significant loss of revenue.

The federal physician self-referral law, commonly referred to as the Stark Law, prohibits a physician from making a Medicare or Medicaid reimbursed referral for a “designated health service” to an entity if the physician or a member of the physician’s immediate family has a “financial relationship” with the entity unless an exception applies. The list of “designated health services” under the Stark Law does not generally include ambulatory surgery services, but it does include inpatient and outpatient hospital service and services such as clinical laboratory services, and certain imaging services that may be provided and separately billed by an ASC.ASC or other facility. Under the current Stark Law and related regulations, services provided at an ASC are not covered by the statute, even if those services include imaging, laboratory services or other Stark designated health services, provided that (i) the ASC does not bill for these services separately, or (ii) if the center is permitted to bill separately for these services, they are specifically exempted from Stark Law prohibitions. These are generally radiology and other imaging services integral to performance of surgical procedures that meet certain requirements and certain outpatient prescription drugs. We believe that servicesServices provided at our facilities licensed as hospitals are covered by the Stark Law, but referrals for such services are exempt fromLaw. We attempt to structure our relationship with physicians who refer to our hospitals to meet an exception to the Stark Law under its “whole hospital exception,” which was significantly amended bywhere required, but the Affordable Care Act.regulations implementing the exceptions are detailed and complex, and we cannot guarantee that every relationship complies fully with the Stark Law. We also believe that certain services provided by our managed physician network are covered by the Stark Law, but referrals for those services are exempt from the Stark Law under its “in-office ancillary services exception,” among others. Our diagnostic laboratory is also subject to the Stark Law, but we believe that we have structured our agreements with physicians so as to not violate the Stark Law and related regulations.

The Stark Law and similar state statutes are subject to different interpretations with respect to many important provisions. Violations of these self-referral laws may result in substantial civil or criminal penalties, including treble damages for amounts improperly claimed, civil monetary penalties of up to $15,000 per prohibited service billed, up to $100,000 per prohibited circumvention scheme and exclusion from participation in the Medicare and Medicaid and other federal and state healthcare programs. Violations of the Stark Law will also create liability under the federal False Claims Act. Exclusion of our ASCs or hospitals from these programs through judicial or agency interpretation of

existing laws or additional legislative restrictions on physician ownership or investments in healthcare entities could result in a significant loss of reimbursement revenue. We cannot provide assurances that CMS will not undertake other rulemaking to address additional revisions to or interpretations of the Stark Law regulations. If future rules modify the provisions of the Stark Law regulations that are applicable to our business, our revenue and profitability could be materially adversely affected and could require us to modify our relationships with our physician and healthcare system partners.

The Stark Law includes an exception that permits physicians to refer Medicare and Medicaid patients to hospitals in which they have an ownership interest if certain requirements are met. However, the Affordable Care Act dramatically curtailed this exception and prohibits physician ownership in hospitals that did not have a Medicare provider agreement by December 31, 2010. This prohibition does not apply to anyAs a result, the law effectively prevents the formation of new physician-owned hospitals that participate in Medicare and Medicaid after December 31, 2010. Each of our five surgical hospitals each of which had a Medicare provider agreement in place prior to December 31, 2010 and areis therefore able to continue operating with their pre-IPO Ownership structure.the ownership structure that was in place prior to December 30, 2010. However, the Affordable Care Act prohibits “grandfathered” hospitals from increasing their percentage of physician ownership, and it limits to a certain extent their ability to grow, because it prohibits such hospitals from increasing the aggregate number of inpatient beds, operating rooms and procedure rooms.

Companies within the healthcare industry continue to be the subject of federal and state audits and investigations, and we may be subject to such audits and investigations, including actions for false and other improper claims.

Federal and state government agencies, as well as commercial payors, have increased their auditing and administrative, civil and criminal enforcement efforts as part of numerous ongoing investigations of healthcare organizations. These audits and investigations relate to a wide variety of topics, including the following: cost reporting and billing practices; quality of care; financial reporting; financial relationships with referral sources; and medical necessity of services provided. In addition, the Office of the Inspector General of the U.S. Department of Health and Human Services (the “OIG”)OIG and the U.S. Department of Justice (“DOJ”) have, from time to time, undertaken national enforcement initiatives that focus on specific billing practices or other suspected areas of abuse. In its 2013 Work Plan, the OIG stated its intention to review the safety and quality of care for Medicare beneficiaries having surgeries and procedures in ASCs and hospital outpatient departments. We have not received any material related audit letters to date.

The federal government is authorized tomay impose criminal, civil and administrative penalties on any person or entity that files a false claim for payment from the Medicare or Medicaid programs and other federal and state healthcare programs. Claims filed with private insurers can also lead to criminal and civil penalties, including, but not limited to, penalties relating to violations of federal mail and wire fraud statutes, as well as penalties under the anti-fraud provisions of the HIPAA (as defined below).HIPAA. While the criminal statutes are generally reserved for instances of fraudulent intent, the federal government is applying its criminal, civil and administrative penalty statutes in an ever-expanding range of circumstances, including claiming payment for unnecessary services if the claimant merely should have known the services were unnecessary and claiming payment for low-quality services if the claimant should have known that the care was substandard. In addition, a violation of the Stark Law or the Anti-Kickback Statute can result in liability under the federal False Claims Act ("FCA").

Over the past several years, the federal government has investigated an increasing number of healthcare providers for potential FCA violations, which, among other things, prohibits a person from knowingly presenting, or causing to be presented, a false or fraudulent claim to the federal government. The statute defines “knowingly” to include not only actual knowledge of a claim’s falsity, but also reckless disregard for or intentional ignorance of the truth or falsity of a claim. Violators of the FCA are subject to severe financial penalties, including treble damages and per claim penalties in excess of $10,000. Because our facilities perform hundreds or thousands of similar procedures each year for which they are paid by Medicare, and since the statute of limitations for such claims extends for six years under

Moreover, another trend impacting healthcare providers is the increased use of the FCA, particularly by individuals who bring actions under that law. Under the “qui tam,” or whistleblower, provisions of the FCA, private parties may bring actions on behalf of the federal government. If the government intervenes and prevails in the action, the defendant may be required to pay three times the actual damages sustained by the government, plus mandatory civil monetary penalties of between $5,500 and $11,000 for each false claim submitted to the government. These private parties, often referred to as relators, are entitled to share in any amounts recovered by the government through trial or settlement. These qui tam cases are sealed by the court at the time of filing. The only parties privy to the information contained in the complaint are the relator, the federal government and the presiding court. It is possible that qui tam lawsuits have been filed against us and that we are unaware of such filings. Both direct enforcement activity by the government and whistleblower lawsuits under the FCA have increased significantly in recent years; thus, the risk that we will have to defend a false claims action, pay significant fines or be excluded from the Medicare and Medicaid programs has increased. For example, on October 23, 2017, the Company received a civil investigative demand (“CID”) from the federal government under the False Claims Act (“FCA”) for documents and information dating back to January 1, 2010 relating to the medical necessity of certain drug tests conducted by the Company’s physicians and submitted to laboratories owned and operated by the Company. The Company intends to respond to the CID and cooperate with the U.S. Attorney’s Office in connection with the FCA investigation.

In addition, the Fraud Enforcement and Recovery Act of 2009 (“FERA”) further expanded the scope of the FCA to create liability for knowingly and improperly avoiding or decreasing an obligation to pay money to the federal government and FERA, along with statutory provisions found in the Acts, created federal False Claims Act liability for the knowing failure to report and return an overpayment within 60 days of the identification of the overpayment or, in certain cases, the date by which a corresponding cost report is due, whichever is later.

Governmental authorities may challenge or scrutinize our operations or we may be the subject of a whistleblower lawsuit at any time. A determination that we have violated these laws could have a material adverse effect on our business, prospects, results of operations and financial condition.

The Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (the “HITECH Act”), and their implementing regulations (collectively referred to as “HIPAA”)HIPAA also created new federal criminal statutes that prohibit among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

In addition, a person who offers or transfers to a Medicare or Medicaid beneficiary any remuneration, including waivers of co-payments and deductible amounts (or any part thereof), that the person knows or should know is likely to influence the beneficiary’s selection of a particular provider, practitioner or supplier of Medicare or Medicaid payable items or services may be liable for civil monetary penalties of up to $10,000 for each wrongful act. Moreover, in certain cases, providers who routinely waive copayments and deductibles for Medicare and Medicaid beneficiaries can also be held liable under the Anti-Kickback Statute and civil False Claims Act, which can impose additional penalties associated with the wrongful act. Although this prohibition applies only to federal healthcare program beneficiaries, the routine waivers of copayments and deductibles offered to patients covered by commercial payors may implicate applicable state laws related to, among other things, unlawful schemes to defraud, excessive fees for services, tortious interference with patient contracts and statutory or common law fraud. To the extent our patient assistance programs or other discount policies are found to be inconsistent with applicable laws, we may be required to restructure or discontinue such programs, or be subject to other significant penalties.

To enforce compliance with the federal laws, the DOJ has recently increased its scrutiny of interactions between health care companies and health care providers, which has led to a number of investigations, prosecutions, convictions and settlements in the health care industry. Dealing with investigations can be time and resource consuming and can divert management’s attention from the business. In addition, settlements with the DOJ or other law enforcement agencies have forced healthcare providers to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business.

We are also subject to various state laws and regulations, as well as contractual provisions with commercial payors that prohibit us from submitting inaccurate, incorrect or misleading claims. We cannot be sure that none of our surgical facilities’ claims will ever be challenged. If we were found to be in violation of a state’s laws or regulations, or of a commercial payor contract, we could be forced to discontinue the violative practice and be subject to recoupment actions, fines and criminal penalties, which could have a material adverse effect on our business, prospects, results of operations and financial condition.

All payors are increasingly conducting post-payment audits. For example, CMS has implemented the RAC program, involving Medicare claims audits nationwide. Under the program, CMS contracts with RACs on a contingency fee basis to conduct post-payment reviews to detect and correct improper payments in the fee-for-service Medicare program. The Affordable Care Act expanded the RAC program’s scope to include managed Medicare plans and to include Medicaid claims. In addition, CMS employs Medicaid Integrity Contractors (“MICs”)MICs to perform post-payment audits of Medicaid claims and identify overpayments. The Affordable Care Act increases federal funding for the MIC program. In addition to RACs and MICs, the state Medicaid agencies and other contractors have increased their review activities. We are regularly subject to these external audits and we also perform both internal and third-party audits and monitoring.

Failure to comply with Medicare’s conditions for coverage and conditions of participation may result in loss of program payment or other governmental sanctions.

To participate in and receive payment from the Medicare program, our facilities must comply with regulations promulgated by CMS. These regulations, known as “conditions for coverage” for ASCs and “conditions of participation” for hospitals, set forth specific requirements with respect to, among other things, the facility’s physical plant, equipment, personnel and standards of medical care. All of our surgery centers and surgical hospitals are certified to participate in the Medicare program. As such, these facilities are subject to on-site, unannounced surveys by state survey agencies working on behalf of CMS. Under the ASC survey process, the surveyors are becoming more familiar with expanded interpretive guidance and the updated ASC conditions for coverage, which may lead to an increased number of deficiency citations requiring remedy with appropriate action plans. Failure to comply with Medicare’s conditions for coverage or conditions of participation may result in loss of payment or other governmental sanctions, including termination from participation in the Medicare program. We have established ongoing quality assurance activities to monitor our facilities’ compliance with these conditions and respond to surveys, but we cannot be sure that our facilities are or will always remain in full compliance with the requirements. In addition, pending a determination regarding our compliance with these conditions, payment to us may be suspended and we may be required to devote significant time, effort and expense to demonstrate satisfactory compliance.

Our use and disclosure of personally identifiable information, including health information, is subject to federal and state privacy and security regulations, and our failure to comply with those regulations or to adequately secure the information we hold could result in significant liability or reputational harm.

HIPAA as well as numerous other federal and state laws and regulations, govern the collection, dissemination, use, privacy, security, confidentiality, integrity and availability of personally identifiable information (“PII”), including protected health information (“PHI”). HIPAA applies national privacy and security standards for PHI to covered entities such as us. HIPAA requires covered entities to maintain policies and procedures governing PHI that is used or disclosed, and to implement administrative, physical and technical safeguards to protect PHI, including PHI maintained, used and disclosed in electronic form. These safeguards include teammate training, identifying “business associates” with whom we need to enter into HIPAA-compliant contractual arrangements and various other measures. Ongoing implementation and oversight of these measures involves significant time, effort and expense. While we undertake substantial efforts to secure the PHI we maintain, use and disclose in electronic form, a cyber-attack or other intrusion that bypasses our information security systems causing an information security breach, loss of protected health information or other data subject to privacy laws or a material disruption of our operational systems could result in a material adverse impact on our business, along with potentially substantial fines and penalties. Ongoing implementation and oversight of these security measures involves significant time, effort and expense.

HIPAA also requires our surgical facilities to use standard transaction code sets and identifiers for certain standardized healthcare transactions, including billing and other claim transactions. We have undertaken significant efforts involving substantial time and expense to implement these requirements, and we anticipate that continual time and expense will be required to submit standardized transactions and to ensure that any newly acquired facilities can submit HIPAA-compliant transactions.

HIPAA requires covered entities to report breaches of unsecured protected health information to affected individuals without unreasonable delay and in no case later than 60 days after the discovery of the breach by the covered entity or its agents. Notification must also be made to HHS and, in certain situations involving large breaches, to the media. The HIPAA rules created a presumption that all non-permitted uses or disclosures of unsecured protected health information are breaches unless the covered entity establishes that there is a low probability the information has been compromised. HIPAA imposes mandatory civil and criminal penalties for violations of its requirements ranging up to $50,000 per violation, with a maximum civil penalty of $1.5 million in a calendar year for violations of the same requirement. However, a single breach incident can result in violations of multiple requirements, resulting in possible penalties well in excess of $1.5 million. In addition, the HITECH Act authorized state attorneys general to bring civil actions seeking either an injunction or damages in response to violations of HIPAA privacy and security regulations that threaten the privacy of state residents.

HIPAA also authorizes state attorneys general to bring civil actions seeking either an injunction or damages in response to violations of HIPAA privacy and security regulations that threaten the privacy of state residents. While HIPAA does not create a private right of action allowing individuals to sue us in civil court for violations of HIPAA’s requirements, its standards have been used as a basis for the duty of care in state civil suits, such as those for negligence or recklessness in the handling of PHI. In addition, HIPAA mandates that the Secretary of HHS conduct periodic compliance audits of HIPAA covered entities such as us.

In addition, many states in which we operate may impose laws that are more protective of the privacy and security of PII than HIPAA. Where these state laws are more protective than HIPAA, we have to comply with their stricter provisions. Only some of these state laws impose fines and penalties upon violators, but some may afford private rights of action to individuals who believe their PII has been misused. California’s patient privacy laws, for example, provide for penalties of up to $250,000 and permit injured parties to sue for damages. Both state and federal laws are subject to modification or enhancement of privacy protection at any time. Our facilities will continue to remain subject to any federal or state privacy-related laws that are more restrictive than the privacy regulations issued under HIPAA. These statutes vary and could impose additional requirements on us and more severe penalties for disclosures of confidential health information. New health information standards could have a significant effect on the manner in which we do business, and the cost of complying with new standards could be significant. We may not remain in compliance with the diverse privacy requirements in all of the jurisdictions in which we do business. If we fail to comply with HIPAA or similar state laws, we could incur substantial civil monetary or criminal penalties.

Our operations depend significantly on effective information systems, which require continual maintenance, upgrading and enhancement to meet our operational needs. Any system failure or integration delay that causes an interruption in service or availability of our systems could

adversely affect operations or delay the collection of revenue. Moreover, we use the development and implementation of sophisticated and specialized technology to improve our profitability, and our growthacquired surgical centers and acquisition strategyhospitals will require frequent transitions and integration of various information systems. If we are unable to properly integrate other information systems or expand our current information systems it may have an adverse effect on our ability to obtain new business, retain existing business and maintain or increase our profit margins and we could suffer, among other things, operational disruptions, disruptions in cash flows and increases in administrative expenses.

Information security risks have generally increased in recent years because of threats from malicious persons and groups, new vulnerabilities, the proliferation of new technologies and the increased sophistication and activities of perpetrators of cyber-attacks. A failure in or breach of our operational or information security systems as a result of cyber-attacks or information security breaches could disrupt our business, result in the loss, disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs or lead to fines and financial losses. As a result, cyber security and the continued development and enhancement of the controls and processes designed to protect our systems, computers, software, data and networks from attack, damage or unauthorized access remain a priority for us. Although we believe that we have robust information security procedures and other safeguards in place, asAs cyber threats continue to evolve, we maywill be required to expend additional resources to continue to enhance our information security measures or to investigate and remediate any information security vulnerabilities.

EffortsState efforts to regulate the construction, acquisition or expansion of healthcare facilities could prevent us from acquiring additional surgical facilities, renovating our existing facilities or expanding the breadth of services we offer.

Some states require prior approval for the construction, acquisition or expansion of healthcare facilities or expansion of the services the facilities offer. In giving approval, these states consider the need for additional or expanded healthcare facilities or services, as well as the financial resources and operational experience of the potential new owners of existing healthcare facilities. In many of the states in which we currently operate, certificates of need must be obtained for capital expenditures exceeding a prescribed amount, changes in capacity or services offered and various other matters. The remaining states in which we now or may in the future operate may adopt similar legislation. Our costs of obtaining a certificate of need could be significant, and we cannot assure you that we will be able to obtain the certificates of need or other required approvals for additional or expanded surgical facilities or services in the future. In addition, at the time we acquire a surgical facility, we may agree to replace or expand the acquired facility. If we are unable to obtain required approvals, we may not be able to acquire additional surgical facilities, expand healthcare services we provide at these facilities or replace or expand acquired facilities.

If antitrust enforcement authorities conclude that our market share in any particular market is too concentrated, that our or our health system partners’ commercial payor contract negotiating practices are illegal, or that we other violate antitrust laws, we could be subject to enforcement actions that could have a material adverse effect on our business, prospects, results of operations and financial condition.

The federal government and most states have enacted antitrust laws that prohibit certain types of conduct deemed to be anti-competitive. These laws prohibit price fixing, concerted refusal to deal, market monopolization, price discrimination, tying arrangements, acquisitions of competitors and other practices that have, or may have, an adverse effect on competition. Violations of federal or state antitrust laws can result in various sanctions, including criminal and civil penalties. Antitrust enforcement in the healthcare industry is currently a priority of the Federal Trade Commission (the “FTC”). We believe we are in compliance with federal and state antitrust laws, but courts or regulatory authorities may reach a determination in the future that could have a material adverse effect on our business, prospects, results of operations and financial condition.

The healthcare laws and regulation to which we are subject is constantly evolving and may change significantly in the future.

The regulation applicable to our business and to the healthcare industry generally to which we are subject is constantly in a state of flux. While we believe that we have structured our agreements and operations in material compliance with applicable healthcare laws and regulations, there can be no assurance that we will be able to successfully address changes in the current regulatory environment. We believe that our business operations materially comply with applicable healthcare laws and regulations. However, some of the healthcare laws and regulations applicable to us are subject to limited or evolving interpretations, and a review of our business or operations by a court, law enforcement or a regulatory authority might result in a determination that could have a material adverse effect on us. Furthermore, the healthcare laws and regulations applicable to us may be amended or interpreted in a manner that could have a material adverse effect on our business, prospects, results of operations and financial condition.

There can be no assurance as to the period of time during which H.I.G.we will maintain its ownership of our common stock.remain a “controlled company”.

H.I.G.Our controlling stockholder has significant influence over us, including control over decisions that require the approval of stockholders, which could limit our stockholders’ ability to influence the outcome of key transactions, including a change of control.

Our stock price could be extremely volatile, and, as a result, our stockholders may not be able to resell their shares at or above the price paid for them.

The stock market in general has been highly volatile. As a result,Since our initial public offering, the market price of our common stock is likelyas reported on The NASDAQ Global Select Market has ranged from a low of $7.10 on November 1, 2017 to be similarly volatile, and investors in our common stock may experience a decrease, which could be substantial, in the valuehigh of their stock, including decreases unrelated to our operating performance or prospects, and could lose part or all of their investment.$24.05 on June 28, 2017. The price of our common stock could be subject to wide fluctuations in response to a number of factors, including those described elsewhere in this report and others such as:

In the past, securitiesSecurities class action litigation hasis often been initiated against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources, and could also require us to make substantial payments to satisfy judgments or to settle litigation.

Our certificate of incorporation and by-laws, the certificate of designation governing our preferred stock and Delaware law contain provisions that could make it harder for a third party to acquire us, even if doing so might be beneficial to our stockholders. TheseThe provisions in our organizational documents include a classified board of directors and limitations on actions by our stockholders. In addition, our board of directors has the right to issue additional preferred stock without stockholder approval that could be used to dilute a potential hostile acquiror. Our certificate of incorporation also imposes some restrictions on mergers and other business combinations between us and any holder of 15.0% or more of our outstanding common stock other than affiliates of H.I.G..Bain Capital. Finally, our 10% Series A Convertible Perpetual Participating Preferred Stock accrues conversion value for each quarter it is outstanding and is subject, under certain circumstances, to a redemption premium, which could significantly increase the cost to a potential acquirer of buying all of the outstanding securities of the Company. As a result of these features, our stockholders may lose their ability to sell their stock for a price in excess of the prevailing market price, due to these protective measures, and efforts by stockholders to change the direction or management of the Company may be unsuccessful.

Our amended and restated certificate of incorporation designates courts in the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated certificate of incorporation provides that, subject to limited exceptions, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim against us arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws or (iv) any other action asserting a claim against us that is governed by the internal affairs doctrine (each, a “Covered Proceeding”). In addition, our amended and restated certificate of incorporation provides that if any action the subject matter of which is a Covered Proceeding is filed in a court other than the specified Delaware courts without the approval of our board of directors (each, a “Foreign Action”), the claiming party will be deemed to have consented to (i) the personal jurisdiction of the specified Delaware courts in connection with any action brought in any such courts to enforce the exclusive forum provision described above and (ii) having service of process made upon such claiming party in any such enforcement action by service upon such claiming party’s counsel in the Foreign Action as agent for such claiming party. Any person or entity purchasing or otherwise acquiring any interest in shares of our stock shall be deemed to have notice of and to have consented to these provisions. These provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and employees. Alternatively, if a court were to find these provisions of our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition.

If securities or industry analysts do not continue to publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. If securities or industry analysts ceases coverage of us or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price and trading volume to decline. If one or more of the analysts who covers us downgrades our common stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline.
