SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation	Principles of Consolidation Our consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All material intercompany transactions and balances have been eliminated in the accompanying consolidated financial statements.
Use of Estimates and Assumptions	Use of Estimates and Assumptions The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the use of estimates and assumptions that affect the reported amounts of revenues, expenses, assets, liabilities and contingencies. Although actual results in subsequent periods may differ from these estimates, such estimates are developed based on the best information available to management and based on management’s best judgments at the time. We base our estimates on historical experience, observable trends and various other assumptions that we believe are reasonable under the circumstances. All significant assumptions and estimates underlying the amounts reported in the consolidated financial statements and accompanying notes are regularly reviewed and updated when necessary. Changes in estimates are reflected prospectively in the consolidated financial statements based upon on-going actual trends, or subsequent settlements and realizations depending on the nature and predictability of the estimates and contingencies. Interim changes in estimates related to annual operating costs are applied prospectively within annual periods. Although we believe that our estimates are reasonable, actual results could differ from these estimates. The most significant assumptions and estimates underlying these consolidated financial statements and accompanying notes involve revenue recognition and accounts receivable valuation, inventories, accounts payable and accrued liabilities (including self-insurance reserves and contingencies), impairments of long-lived assets including goodwill, income taxes, business combinations, leases and stock-based compensation.
Revenue Recognition	Revenue Recognition Patient Care Segment Revenues in our Patient Care segment are primarily derived from the sale of O&P devices and are recognized when the patient has received the device or service. At or subsequent to delivery, we issue an invoice to a third party payor, which primarily consists of commercial insurance companies, Medicare, Medicaid, the Veterans Administration and private or patient pay (“Private Pay”). We recognize revenue for the amounts we expect to receive from payors based on expected contractual reimbursement rates, which are net of estimated contractual discounts. Government reimbursement, comprised of Medicare, Medicaid and the U.S. Department of Veterans Affairs, in the aggregate, accounted for approximately, 54.1%, 53.4% and 50.9% of our net revenue in 2016, 2015 and 2014, respectively. These revenue amounts are further revised as claims are adjudicated, which may result in disallowances, or decreases to revenue. We believe that adjustments related to write-offs of receivables should predominantly be recorded as a reduction of revenues, which we refer to as disallowed revenue. This is due to the majority of our revenues being collected from commercial insurance companies, Medicare, Medicaid and the Veterans Administration, most of which are under contractual reimbursement rates. As such, adjustments do not relate to an inability to pay, but to contractual allowances, lack of timely claims submission, insufficient medical documentation or other administrative errors. Amounts recorded to bad debt expense, which are presented within “Other operating costs,” generally relate to commercial payor bankruptcies and private pay balances for which there was an assessment of collectability and collection attempts were made. At the end of each period, we establish allowances for estimated disallowances relating to that period based on prior adjudication experience and record such amounts as an adjustment to revenue. In a similar fashion, we estimate and record allowances for doubtful accounts on unpaid receivables at each period end. We also record a liability, with a corresponding adjustment to revenue, for refunds expected to be paid to our patients or third party payors. Medicare and Medicaid regulations and the various agreements we have with other third party payors, including commercial healthcare providers under which these contractual adjustments and disallowed revenue are calculated, are complex and are subject to interpretation and adjustment and may include multiple reimbursement mechanisms for different types of services. Therefore, the particular O&P devices and related services authorized and provided, and the related reimbursement, are subject to interpretation and adjustment that could result in payments that differ from our estimates. Additionally, updated regulations and reimbursement schedules, and contract renegotiations occur frequently, necessitating regular review and assessment of the estimation process by management. As a result, there is a reasonable possibility that recorded estimates will change materially in the short-term and any related adjustments will be recorded as changes in estimates when they become known. For more information on our use of estimates to calculate allowances for disallowed revenue and doubtful accounts, refer to the “Accounts Receivable, Net” section below. We often invoice patients or payors after a device is delivered. To account for this delay, we record an estimated revenue accrual for devices delivered but not yet invoiced at period end. This estimate is based on a historical look-back analysis of lag times between delivery and invoicing that occur over a period end. Products & Services Segment Revenues in our Products & Services segment are derived from the distribution of O&P components and the leasing and sale of rehabilitation equipment and ancillary consumable supplies combined with equipment maintenance, education, and training. Distribution revenues are recorded upon the delivery of products, net of estimated returns. Equipment leasing and related services revenue are recognized over the applicable term as the customer has the right to use the equipment and as the services are provided. Equipment sales revenue is recognized upon delivery, with any related services revenue deferred and recognized as the services are performed. Sales of consumables are recognized upon delivery.
Material Costs	Material Costs Material costs in our Patient Care segment reflect purchases of orthotics and prosthetic componentry and other related costs in connection with the delivery of care through our clinic locations and other patient care operations. Material costs in our Products & Services segment reflect purchases of orthotics and prosthetic materials and other related costs in connection with the distribution of products and services to third party customers.
Personnel Costs	Personnel Costs Personnel costs reflect salaries, benefits, incentive compensation, contract labor, and other personnel costs we incur in connection with our delivery of care through our clinic locations and other patient care operations, or distribution of products and services, and exclude similar costs incurred in connection with general and administrative activities.
Other Operating Costs	Other Operating Costs Other operating costs reflect costs we incur in connection with our delivery of care through our clinic locations and other patient care operations or distribution of products and services. Marketing costs, including advertising, are expensed as incurred and are presented within this financial statement caption. We incurred approximately $4.0 million, $3.9 million, and $3.4 million in advertising costs during the years ended December 31, 2016, 2015 and 2014, respectively. Other costs include rent, utilities, and other occupancy costs, general office expenses, bad debt expense, and travel and clinical professional education costs, and exclude similar costs incurred in connection with general and administrative activities.
General and Administrative Expenses	General and Administrative Expenses General and administrative expenses reflect costs we incur in the management and administration of our businesses that are not directly related to the operation of our clinics or provision of products and services. These include personnel costs and other operating costs supporting our general and administrative functions. We incurred approximately $0.6 million, $0.6 million, and $0.7 million in advertising costs during the years ended December 31, 2016, 2015 and 2014, respectively.
Professional Accounting and Legal Fees	Professional Accounting and Legal Fees We recognize fees associated with audits of our financial statements in the fiscal period to which the audit relates. All other professional fees are generally recognized as expense in the periods in which services are performed. Please see the “Accounts Payable and Accrued Liabilities” section for legal fees associated with legal contingencies.
Depreciation and Amortization	Depreciation and Amortization Depreciation and amortization expenses reflect all depreciation and amortization expenses, whether incurred in connection with our delivery of care through clinic locations, our distribution of products and services, or in the general management and administration of our business.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. We maintain cash balances in excess of Federal Deposit Insurance Corporation (“FDIC”) limits at certain financial institutions. We manage this credit risk by concentrating our cash balances in high quality financial institutions and by periodically evaluating the credit quality of the primary financial institutions holding such deposits. With short maturities, the investments present insignificant risk of changes in value because of interest rate changes and are readily convertible to cash. Historically, no losses have been incurred due to such cash concentrations. Restricted cash balances are presented within “Other current assets” in the consolidated balance sheets. See Note I - “Other Current Assets and Other Assets” within these consolidated financial statements.
Accounts Receivable, Net	Accounts Receivable, Net Patient Care Segment We establish allowances for accounts receivable to reduce the carrying value of such receivables to their estimated net realizable value. The Patient Care segment’s accounts receivables are recorded net of unapplied cash, estimated allowance for disallowed revenue and estimated allowance for doubtful accounts, as described in the revenue recognition accounting policy above. Both the allowance for disallowed revenue and the allowance for doubtful accounts estimates consider historical collection experience by each of the Medicare and non-Medicare (commercial insurance, Medicaid, Veteran’s Administration and Private Pay) primary payor class groupings. For each payor class grouping, liquidation analysis of historical period end receivable balances are performed to ascertain collections experience by aging category. We believe the use of historical collection experience applied to current period end receivable balances is reasonable. In the absence of an evident adverse trend, we use historical experience rates calculated using an average of four quarters of data with at least twelve months of adjudication. We believe the time periods analyzed provide sufficient time for most balances to adjudicate in the normal course of operations. We will modify the time periods analyzed when significant trends indicate that adjustments should be made. In addition, estimates are adjusted when appropriate for information available up through the issuance of the consolidated financial statements. Products & Services Segment Products & Services segment’s allowance for doubtful accounts is estimated based on the analysis of the segment’s historical write-offs experience, accounts receivable aging and economic status of its customers. Accounts receivable that are deemed uncollectible are written-off to the allowance for doubtful accounts. Accounts receivable are also recorded net of an allowance for estimated sales returns.
Inventories	Inventories Inventories are valued at the lower of estimated cost or net realizable value with cost determined on a first-in, first out (“FIFO”) basis. Provisions have also been made to reduce the carrying value of inventories for excess, obsolete, or otherwise impaired inventory on hand at period-end. Patient Care Segment Substantially all of our Patient Care segment inventories are recorded through a periodic approach whereby inventory quantities are adjusted on the basis of a quarterly physical count. Segment inventories relate primarily to raw materials and work-in-process (“WIP”) at Hanger Clinics. Inventories at Hanger Clinics totaled $29.1 million and $30.1 million at December 31, 2016 and 2015, respectively, with WIP inventory representing $9.0 million and $8.9 million of the total inventory, respectively. Raw materials consists of purchased parts, components, and supplies which are used in the assembly of O&P devices for delivery to patients. In some cases, purchased parts and components are also sold directly to patients. Raw materials are valued based on recent vendor invoices, reduced by estimated vendor rebates. Such rebates are recognized as a reduction of cost of materials in the Consolidated Statements of Operations and Comprehensive (Loss) Income when the related devices or components are delivered to the patient. Approximately 69% and 52% of raw materials at December 31, 2016 and 2015, respectively were purchased from our Products & Services segment. Raw material inventory was $20.1 million and $21.2 million at December 31, 2016 and 2015 respectively. WIP consists of devices which are in the process of assembly at our clinics or fabrication centers. WIP quantities were determined by the physical count of patient orders at the end of every quarter of 2016 and 2015 while the related stage of completion of each order was established by clinic personnel. We do not have an inventory costing system and as a result, the identified WIP quantities were valued on the basis of estimated raw materials, labor, and overhead costs. To estimate such costs, we develop bills of materials for certain categories of devices that we assemble and deliver to patients. Within each bill of material, we estimate (i) the typical types of component parts necessary to assemble each device; (ii) the points in the assembly process when such component parts are added; (iii) the estimated cost of such parts based on historical purchasing data; (iv) the estimated labor costs incurred at each stage of assembly; and (v) the estimated overhead costs applicable to the device. Products & Services Segment Product & Service segment inventories consist primarily of finished goods at its distribution centers as well as raw materials at fabrication facilities, and totaled $39.1 million and $38.4 million as of December 31, 2016 and 2015, respectively. Finished goods include products that are available for sale to third party customers as well as to our Patient Care segment as described above. Such inventories were determined on the basis of perpetual records and a physical count at year end. Inventories in connection with therapeutic services are valued at a weighted average cost.
Fair Value Measurements	Fair Value Measurements We follow the authoritative guidance for financial assets and liabilities, which establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. The authoritative guidance requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy by which these assets and liabilities must be categorized, based on significant levels of inputs as follows: Level 1 consists of securities for which there are quoted prices in active markets for identical securities; Level 2 consists of securities for which observable inputs other than Level 1 inputs are used, such as quoted prices for similar securities in active markets or quoted prices for identical securities in less active markets and model-derived valuations for which the variables are derived from, or corroborated by, observable market data; and Level 3 consists of securities for which there are no observable inputs to the valuation methodology that are significant to the measurement of the fair value. The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
Financial Instruments	Financial Instruments We hold investments in money market funds which are measured at fair value on a recurring basis. As of December 31, 2016 and 2015, $2.3 million and $3.9 million, respectively of money market funds which are restricted from general use are presented within “Other current assets.” The fair values of our money market funds are based on Level 1 observable market prices and are equivalent to one dollar per share. The carrying value of accounts receivable and accounts payable, approximate their fair values based on the short-term nature of these instruments. The carrying value of our outstanding term loan as of December 31, 2016 and 2015, was $180.0 million and $199.7 million compared to its fair value of $172.6 million and $186.2 million, respectively. The carrying values of our outstanding Term Loan B as of December 31, 2016 was $280.0 million compared to its fair value of $278.6 million. There was no Term Loan B outstanding as of December 31, 2015. Our estimates of fair value are based on debt with similar terms and remaining maturities as of December 31, 2016 and 2015, which represent Level 2 measurements. We had no balances outstanding under revolving credit facilities as of December 31, 2016. The carrying value of the amount outstanding on our revolving credit facilities as of December 31, 2015, was $132.0 million compared to its fair value of $121.6 million. Our estimates of fair value are based on debt with similar terms and remaining maturities as of December 31, 2015, which represent a Level 2 measurement. Our senior notes were redeemed during 2016. The carrying value of the senior notes was $200.0 million as of December 31, 2015 compared to their fair value of $179.2 million. Our estimates of fair value are based on observable market inputs which represent Level 2 measurements. The carrying value of our outstanding subordinated promissory notes issued in connection with acquisitions (“Seller Notes”) as of December 31, 2016 and 2015 was $11.1 million and $19.8 million, respectively. We believe that the carrying value of the Seller Notes approximates their fair values based on a discounted cash flow model using unobservable inputs, primarily, our credit spread for subordinated debt, which represents a Level 3 measurement.
Insurance Recoveries Receivable	Insurance Recoveries Receivable We incur legal and other costs with respect to a variety of issues on an ongoing basis. We record a related receivable when costs are reimbursable under applicable insurance policies, we believe it is probable such costs will be reimbursed and such reimbursements can be reasonably estimated. We record the benefit of related receivables from the insurer as a reduction of costs in the same financial statement caption in which the related loss was recognized in our consolidated statements of operations and comprehensive (loss) income. Loss contingency reserves, which are recorded within accrued liabilities, are not reduced by estimated insurance recoveries.
Property, Plant and Equipment, Net	Property, Plant and Equipment, Net Property, plant and equipment are recorded at cost less accumulated depreciation and amortization, with the exception of assets acquired through acquisitions, which are initially recorded at estimated fair value. Equipment acquired under a capital lease is recorded at the present value of the future minimum lease payments. The cost and related accumulated depreciation of assets sold, retired or otherwise disposed of are removed from the respective accounts, and any resulting gains or losses are included in the consolidated statements of operations and comprehensive (loss) income. Depreciation is computed for financial reporting purposes using the straight-line method over the useful lives of the related assets estimated as follows: furniture and fixtures, equipment and information systems, principally five years, buildings ten to forty years, capital leases over the lease term, and leasehold improvements over the shorter of ten years or the lease term. We record maintenance and repairs, including the cost of minor replacements, to maintenance expense. Costs of major repairs that extend the effective useful life of property are capitalized and depreciated accordingly. We capitalize the costs of obtaining or developing internal use software, including external direct costs of materials and services and directly related payroll costs. Amortization begins when the internal use software is ready for its intended use. Costs incurred during the preliminary project and post-implementation stages, as well as maintenance and training costs, are expensed as incurred.
Business Combinations	Business Combinations We record tangible and intangible assets acquired and liabilities assumed in business combinations under the acquisition method of accounting. Acquisition consideration typically includes cash payments, the issuance of Sellers Notes and in certain instances contingent consideration with payment terms associated with the achievement of designated collection targets of the acquired business. Amounts paid for each acquisition are allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition inclusive of identifiable intangible assets. The estimated fair value of identifiable assets and liabilities, including intangibles, are based on detailed valuations that use information and assumptions available to management. We allocate any excess purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed to goodwill. Significant management judgments and assumptions are required in determining the fair value of assets acquired and liabilities assumed, particularly acquired intangible assets, including estimated useful lives. The valuation of purchased intangible assets is based upon estimates of the future performance and discounted cash flows from the acquired business. Each asset acquired or liability assumed is measured at estimated fair value from the perspective of a market participant. Subsequent changes in the estimated fair value of contingent consideration are recognized as “General and administrative expenses” within the consolidated statements of operations and comprehensive (loss) income.
Goodwill and Other Intangible Assets, Net	Goodwill and Other Intangible Assets, Net Goodwill represents the excess of the purchase price over the estimated fair value of net identifiable assets acquired and liabilities assumed from purchased businesses. We assess goodwill for impairment annually during the fourth quarter, and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. We have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If it is determined that a two-step goodwill impairment test is necessary or more efficient than a qualitative approach, we will measure the fair value of the reporting units using a combination of income and market approaches. Any impairment would be recognized by a charge to income from operations and a reduction in the carrying value of the goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, and the second step of the impairment test is not required. The second step, if required, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. The fair value of a reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. If the carrying amount of the reporting unit’s goodwill exceeds its implied fair value, an impairment charge is recognized in an amount equal to that excess. We apply judgment in determining the fair value of our reporting units and the implied fair value of goodwill which is dependent on significant assumptions and estimates regarding expected future cash flows, terminal value, changes in working capital requirements, and discount rates. The fair value of acquired customer intangibles is estimated using an excess earnings model. Key assumptions utilized in the valuation model include pro-forma projected cash flows adjusted for market-participant assumptions, forecasted customer retention curve, and discount rate. Customer intangibles are amortized, using the straight-line method over an estimated useful life of four to ten years. The fair value of non-compete agreements are estimated using a discounted cash flow model. The related intangible assets are amortized, using the straight-line method, over their term which ranges from two to five years. Other definite-lived intangible assets are recorded at cost and are amortized, using the straight-line method, over their estimated useful lives of up to seventeen years. The fair value associated with trade names is estimated using the relief-from-royalty method with the primary assumptions being the royalty rate and expected revenues associated with the trade names. These assets, some of which have indefinite lives, are primarily included in the Products & Services segment. Indefinite lived trade name intangible assets are assessed for impairment in the fourth quarter of each year, or more frequently if events or changes in circumstances indicate that the asset might be impaired. Trade name intangible assets with definite lives are amortized over their estimated useful lives of one to ten years. For the years ended December 31, 2016 and 2015, we recorded impairments of our goodwill totaling $86.0 million and $382.9 million, respectively. See Note H - “Goodwill and Other Intangible Assets” to our consolidated financial statements in this Annual Report on Form 10-K for additional information regarding these charges. In conjunction with our Goodwill impairment testing at December 31, 2015, we reevaluated the estimated useful life of our customer list intangibles. In the fourth quarter of 2015, the estimated useful life of our customer list intangibles was reduced from 10 years to four years in our Patient Care segment and from 14 years to 10 years in our Products & Services segment. This change in the estimated useful lives increased amortization for the years ended December 31, 2015 and 2016 by approximately $6.0 million and $7.0 million, respectively. As described, we apply judgment in the selection of key assumptions used in both steps of the goodwill impairment test and as part of our evaluation of intangible assets tested annually and at interim testing dates as necessary. If these assumptions differ from actual, we could incur additional impairment charges and those charges could be material.
Long-Lived Asset Impairment	Long-Lived Asset Impairment We evaluate the carrying value of long-lived assets to be held and used for impairment whenever events or changes in circumstance indicate that the carrying amount may not be recoverable. The carrying value of a long-lived asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset group. We measure impairment as the amount by which the carrying value exceeds the estimated fair value. Estimated fair value is determined primarily using the projected future cash flows discounted at a rate commensurate with the risk involved. Long-lived assets to be disposed of by sale are classified as held for sale when the applicable criteria are met, and recognized within the consolidated balance sheet at the lower of carrying value or fair value less cost to sell. Depreciation on such assets is ceased.
Debt Issuance Costs, Net	Debt Issuance Costs, Net Debt issuance costs incurred in connection with long-term debt are amortized, on a straight-line basis, which is not materially different from the effective interest method, through the maturity of the related debt instrument. Debt issuance costs are classified as a reduction of debt in the consolidated balance sheets. Amortization of these costs is included within “Interest expense, net” in the consolidated statements of operations and comprehensive (loss) income.
Accounts Payable and Accrued Liabilities	Accounts Payable and Accrued Liabilities Accounts payable relating to goods or services received is estimated using various factors including payments made subsequent to period end, vendor invoice dates, shipping terms confirmed by certain vendors or other third party documentation. Accrued liabilities are recorded based on estimates of services received or amounts expected to be paid to third parties. Accrued legal costs for legal contingencies are recorded when they are probable and estimable.
Self-Insurance Reserves	Self-Insurance Reserves We maintain insurance programs which include employee health insurance, workers’ compensation, product, professional and general liability. Our employee health insurance program is self-funded, with a stop-loss coverage on claims that exceed $0.4 million for any individually covered claim. We are responsible for workers’ compensation, product, professional and general liability claims up to $0.5 million per individual incident. The insurance and self-insurance accruals reflect the estimate of incurred but not reported losses, historical claims experience and expected costs to settle unpaid claims and are undiscounted. We record amounts due from insurance policies in “Other assets” while recording the estimated liability in self-insurance accruals in our consolidated balance sheets.
Leases	Leases We lease a majority of our patient care clinics under lease arrangements, certain of which contain renewal options, rent escalation clauses, and/or landlord incentives. Rent expense for noncancellable leases with scheduled rent increases and/or landlord incentives is recognized on a straight-line basis over the lease term, including any applicable rent holidays, beginning on the earlier of the lease commencement date or the date we take control of the leased space. We have certain building leases that are accounted for as financing transactions. In these instances, pursuant to ASC 840-40-55, The Effect of Lessee Involvement in Asset Construction, we are the deemed owner of the property during the construction phase and the associated building assets and financing obligations are recognized on our consolidated balance sheet. Subsequent to construction, the arrangement is evaluated in accordance with ASC 840-40 to determine whether the arrangement qualifies as a sale leaseback. Sale leasebacks of real estate require an analysis to identify indicators of continuing involvement and other factors. If no indicators of continuing involvement are found, the lease is considered to have passed the sales-leaseback criteria and both the asset and the related financing obligation are derecognized. These leases are then assessed for classification at lease inception and reported in accordance with ASC 840. If indicators of continuing involvement are present, these transactions do not qualify for sale accounting and are accounted for as a failed sale-leaseback. In accordance with ASC 840-40, Leases - Sale-Leaseback Transactions, the buildings and related assets, as well as their associated financing obligations, continue to be reflected in our consolidated balance sheet, with the assets depreciated over their remaining useful lives. Payments required under the arrangement are recognized as reductions of the financing obligation and interest expense. At the end of the lease term, the corresponding financing obligation and the remaining net book value of the building are derecognized. When applicable, any associated gain is recognized within “Other operating costs” in our consolidated statements of operations and comprehensive (loss) income.
Income Taxes	Income Taxes We use the liability method of accounting for income taxes as set forth in the authoritative guidance for accounting for income taxes. Under this method, we recognize deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the respective carrying amounts and tax basis of our assets and liabilities. We recognize a valuation allowance on deferred tax assets if it is more likely than not that the assets will not be realized in future years. Significant accounting judgment is required in determining the provision for income taxes and related consolidated balance sheet accounts. We believe that our tax positions are consistent with applicable tax law, but certain positions may be challenged by taxing authorities. In the ordinary course of business, there are transactions and calculations where the ultimate tax outcome is uncertain. In addition, we are subject to periodic audits and examinations by the Internal Revenue Service and other state and local taxing authorities. In these cases, we record the financial statement effects of a tax position when it is more-likely-than-not, based on the technical merits, that the position will be sustained upon examination. We record the largest amount of tax benefit that is greater than fifty percent likely of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. If not paid, the liability for uncertain tax positions is reversed as a reduction of income tax expense at the earlier of the period when the position is effectively settled or when the statute of limitations has expired. Although we believe that our estimates are reasonable, actual results could differ from these estimates. Interest and penalties, when applicable, are recorded within the income tax provision.
Interest Expense, Net	Interest Expense, Net We record interest expense net of interest income which was $0.1 million in each of the years ended December 31, 2016, 2015 and 2014 in our consolidated statements of operations and comprehensive (loss) income.
Stock-Based Compensation	Stock-Based Compensation We primarily issue restricted common stock units under one active stock-based compensation plan. Shares of common stock issued under this plan are issued from our authorized and unissued shares. We measure and recognize compensation expense, net of estimated forfeiture, for all stock-based payments at fair value. Our outstanding awards are primarily comprised of restricted stock units and performance-based restricted stock units. All employee stock options are fully vested as of December 31, 2016 and 2015, and all associated compensation expense has been recognized in prior years. The restricted stock units are subject to a service condition or vesting period ranging from one to four years. The performance-based restricted stock units include both performance and service conditions. The performance conditions are based on annual earnings per share targets. Compensation expense associated with restricted stock units is recognized on a straight-line basis over the requisite service period. Compensation expense associated with performance-based restricted stock units is recognized on a graded vesting or accelerated basis over the requisite service period when the performance condition is probable of being achieved.
Segment Information	Segment Information We have two segments, Patient Care and Products & Services. Except for the segment specific policies described above, the segments follow the same accounting policies as followed in the consolidated financial statements. We apply the “management approach” to disclosure of segment information. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the basis of our reportable segments. The description of our reportable segments and the disclosure of segment information are presented in Note R “Segment and Related Information” to these consolidated financial statements. Intersegment revenue represents sales of O&P components from our Products & Services segment to our Patient Care segment and are recorded at prices that approximate material cost plus overhead. In 2014, intersegment revenues reflect prices which we believed approximated market values but has been reclassed to eliminate intercompany profit to be consistent with intersegment revenue in 2015 and 2016. The reclassification adjustment to eliminate intersegment profit in 2014 approximates $21.0 million.
Discontinued Operations	Discontinued Operations We reported our Dosteon product group as a discontinued operation in accordance with ASC 205-20, Presentation of Financial Statements-Discontinued Operations, ASC 360-10 Property, Plant and Equipment-Overall, and ASC 350-20, Intangibles -Goodwill and Other - Goodwill as of December 31, 2014 and all subsequent periods. Proceeds from the sale of Dosteon businesses are recorded in the consolidated statement of cash flows within the “Net cash provided by investing activities - discontinued operations” caption. Also included within this caption are any impairments and losses on disposal. See Note S - “Discontinued Operations” within these consolidated financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies what constitutes a modification of a share-based payment award. The ASU is intended to provide clarity and reduce both diversity in practice and cost and complexity when applying the guidance in Topic 718 to a change to the terms or conditions of a share-based payment award. ASU 2017-09 is effective for public entities for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. We plan to adopt ASU 2017-09 on January 1, 2018, and we do not anticipate that the adoption of ASU 2017-09 will have a material impact on our financial conditions or results of operations. In March 2017, the FASB issued ASU No. 2017-7, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost, which include interest cost and prior service cost or credit, among others, are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. This ASU is effective for our fiscal year 2018, including interim periods. We are currently evaluating the effects that the adoption of this ASU will have on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-4, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU simplifies how an entity is required to test goodwill for impairment by eliminating Step Two from the goodwill impairment test. Step Two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, an entity will recognize an impairment charge for the amount by which the carrying value of a reporting unit exceeds it fair value. The amendments in this ASU are effective for us in fiscal year 2020 with early adoption permitted beginning in 2017. We plan to adopt ASU 2017-04 on January 1, 2017. Future impairments, if any, of our goodwill will be impacted by our adoption of this ASU, however any impact cannot be estimated at this time. In January 2017, the FASB issued ASU No. 2017-3, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. This ASU expands disclosures regarding potential material effects to our consolidated financial statements that may occur when adopting ASU’s in the future. When a company cannot reasonably estimate the impact of adopting an ASU, disclosures are to be expanded to include qualitative disclosures including a description to the effect to the company’s accounting policies, a comparison to the existing policies, the status of its process to implement the new standard and any significant implementation matters yet to be addressed. This standard will generally require more disclosure in the consolidated financial statements when adopted. In January 2017, the FASB issued ASU No. 2017-1, Business Combinations (Topic 805): Clarifying the Definition of a Business. This ASU clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This ASU is effective for our fiscal year 2018, including interim periods. The adoption of this standard is not expected to have a material impact on our consolidated financial statements, but may have an impact to the conclusion of future acquisitions. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU provides guidance on presenting restricted cash in the statement of cash flows. Restricted cash and cash equivalents are to be included in cash and cash equivalents when reconciling the changes during the period, while separately identifying the changes in restricted cash and cash equivalents. This ASU is effective for our fiscal year 2018, including interim periods and will require a retrospective transition. Early adoption is permitted. The adoption of this standard will result in restricted cash being included in cash and cash equivalents. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This ASU requires the recognition of the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this standard is not expected to have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The purpose of this ASU is to reduce the diversity in practice regarding how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for fiscal year 2018. Early adoption is permitted. A retrospective transition method is to be used in the application of this amendment. The adoption of this standard is not expected to have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-9, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, although early adoption is permitted. We plan to adopt ASU No. 2016-9 on January 1, 2017, and once effective, we anticipate the primary impact of adopting ASU 2016-9 will be the recognition of excess tax benefits and tax deficiencies resulting from our stock awards to be included in our provision for income taxes, whereas previously these amounts were taken directly to additional paid-in capital. Additionally, these amounts are required to appear in the statement of cash flow under operating activities, whereas previously these amounts were reported as financing activities. We do not anticipate any impact to our classification of awards as either equity or liabilities. Upon the adoption of this ASU, we will elect to account for forfeitures as they occur. In February 2016, the FASB issued ASU No. 2016-2, Leases (Topic 842). The amendments in this ASU revise the accounting for leases. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases that extend beyond 12 months. The asset and liability will initially be measured at the present value of the lease payments. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. The amendments in this ASU are effective for fiscal year 2019 and will be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements. Early adoption is permitted. We are currently evaluating the effects that the adoption of this ASU will have on our consolidated financial statements. We have not yet concluded how the new standard will impact the consolidated financial statements. Nonetheless, it is anticipated that there will be a material increase to assets and lease liabilities for existing property leases representing our nationwide retail locations that are not already included on our consolidated balance sheet through failed sale-leaseback accounting treatment. In January 2016, the FASB issued ASU No. 2016-1, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU revise the accounting related to (i) the classification and measurement of investments in equity securities and (ii) the presentation of certain fair value changes for financial liabilities at fair value. The amendments in this ASU are effective for us beginning on January 1, 2018 and should be applied through a cumulative-effect adjustment to the consolidated balance sheet. Early adoption is permitted under certain circumstances. The adoption of this standard is not expected to have a material impact on our consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which requires that all deferred income tax assets and liabilities be presented as noncurrent in the Company’s consolidated balance sheet. Prior to the issuance of ASU 2015-17, deferred tax liabilities and assets were required to be separately classified into a current amount and a noncurrent amount in the balance sheet. ASU 2015-17 represents a change in accounting principle and is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2016. Early adoption is permitted and the Company elected to early adopt ASU 2015-17 as of December 31, 2015 and applied the guidance retrospectively to all periods presented. The adoption of this guidance resulted in the reclassification of deferred income taxes from a current asset to being reported as a non-current asset. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. The acquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. This guidance is effective for fiscal years beginning after December 15, 2015, and early adoption is permitted. We adopted ASU 2015-16 prospectively effective January 1, 2015. Adoption of ASU 2015-16 did not have a material effect on our consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This ASU simplifies the measurement of inventory. Under this new standard, inventory should be measured using the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonable predictable costs of completion, disposal and transportation. Early adoption is permitted and this ASU was implemented effective January 1, 2015. The adoption of this standard did not have a material impact on our consolidated financial statements. In May 2015, the FASB issued ASU No. 2015-7, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). This ASU removes certain requirements related to valuing assets where fair value is measured using the net asset value per share practical expedient. This ASU was effective on January 1, 2016. The adoption of this standard did not have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Intangibles — Goodwill and Other — Internal-Use Software — Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”). ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance does not change the accounting for a customer’s service contracts. We adopted ASU 2015-05 prospectively effective January 1, 2015. Adoption of ASU 2015-05 did not have a material effect on our consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The amendments in this ASU provide guidance on management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern. We adopted this pronouncement on December 31, 2016, see Note N - “Long-term Debt” for additional information. The adoption of this standard did not have a material effect on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606). This ASU provides a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer in an amount that reflects the consideration it expects to receive in exchange for those goods or services. Additional disclosures are required regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The FASB issued additional related ASU’s providing guidance on principal versus agent considerations, identification of performance obligations and the implementation guidance for licensing. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial adoption. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date which deferred the effective date until fiscal year 2018. We have assembled a revenue task forced composed of internal employees and external consultants to evaluate the impact on the different revenue streams in our consolidated financial statements and related disclosures. We continue to evaluate the impact that the adoption of this new standard may have on our consolidated financial statements and the related disclosures. We expect to adopt any changes resulting from these guidelines effective January 1, 2018. In April 2014, the FASB issued ASU 2014-8, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU changed the requirements for reporting discontinued operations to include a strategic shift that has a major effect on an entity’s operations and financial results. Entities are required to provide additional disclosures about individually significant components that are disposed of, or held for sale, but do not meet the discontinued operations criteria. The ASU was effective prospectively for all disposals or classifications as held for sale that occur within annual periods beginning January 1, 2015. The adoption of this standard did not have a material impact on our consolidated financial statements.
