Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies Basis of Presentation Our accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). All significant intercompany balances and transactions have been eliminated in consolidation. These consolidated financial statements are unaudited and have been prepared by us following the rules and regulations of the U.S. Securities and Exchange Commission. In our opinion they reflect all adjustments, including normal recurring items, that are necessary to present fairly the results of interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted as permitted by such rules and regulations; however, we believe that the disclosures are adequate to make the information presented not misleading. Operating results for the periods presented herein are not necessarily indicative of the results that may be expected for other interim periods or the entire fiscal year. Certain prior year amounts have been reclassified to conform to the current year presentation. Revenue Recognition, Unbilled Receivables and Estimated Liability for Refunds and Appeals We provide services under contracts that contain various fee structures, including performance fee ‑based contracts and fixed fee arrangements. Revenue is recognized when a contract exists, services have been provided to the client, the fee is fixed and determinable and collectability is reasonably assured. We recognize revenue on performance fee based contracts based upon the specific terms of the underlying contract. The contract terms generally specify: (a) time periods covered by the work to be performed; (b) nature and extent of services we are to provide; (c) the client’s duties in assisting and cooperating with us; and (d) fees payable to us. Our fees are most often expressed as a percentage of our findings. Generally, our services are rendered when our clients realize the economic benefits from our services. Our clients realize economic benefits when they take credits against their existing accounts payable based on when we identify cost savings, when they receive refund checks based on overpayments, or when they acknowledge payment reductions based on cost savings. We derive a relatively small portion of revenue on contracts with fixed ‑fee arrangements. We recognize revenue on these contracts ratably over the contract term and once all of the above criteria have been satisfied. Historically, there has been a certain amount of revenue with respect to which, even though we had met the requirements of our revenue recognition policy, the claim is ultimately rejected. In such cases, our clients may request a refund or offset if their providers or vendors ultimately reject the payment inaccuracies we find or if our clients determine not to pursue reimbursement from their providers or vendors even though we may have collected fees. We record any such refund as a reduction of revenue. We record an estimate for refund liabilities at any given time based on actual historical refund data by client type. We satisfy such refund liabilities either by offsets to accounts receivable or by cash payments to clients. In addition to the refund liabilities, we calculate client specific reserves when we determine an additional reserve may be necessary. The estimated liability for refunds and appeals representing our estimate of claims that may be overturned related to revenue which had already been received was $70,574 and $67,775 at June 30, 2016 and December 31, 2015 , respectively. The estimated allowance for refunds and appeals representing our estimate of claims that may be overturned related to amounts in accounts receivable was $45,495 and $33,406 at June 30, 2016 and December 31, 2015 , respectively. Under the Medicare Recovery Audit Program, in which we are one of the four Recovery Audit Contractors (“Medicare RAC”) for CMS, healthcare providers have the right to appeal a claim and may pursue additional appeals if the initial appeal is found in favor of CMS. We accrue an estimated liability for appeals based on the amount of fees that are subject to appeals, closures or other adjustments and those which we estimate are probable of being returned to CMS following a successful appeal by the providers. Our estimates are based on our historical experience with the Medicare RAC appeal process. This estimated liability for Medicare RAC appeals is an offset to revenue in our Consolidated Statements of Comprehensive Income. The liability is included in the estimated liability for refunds and appeals on our Consolidated Balance Sheets. See Note 6 for further information regarding the estimated liability for appeals related to the Medicare RAC program. Unbilled receivables represent revenue recognized related to claims for which clients have received economic value that were not invoiced at the balance sheet date. Unbilled receivables were approximately $50,083 and $51,799 as of June 30, 2016 and December 31, 2015 , respectively and are included in accounts receivable on our Consolidated Balance Sheets. Certain unbilled receivables arise when a portion of our earned fee is deferred at the time of the initial invoice. At a later date (which can be up to a year after original invoice, and at other times during the year after completion of the audit period based on contractual terms or as agreed with our client), we invoice the unbilled receivable amount. Notwithstanding the deferred due date, our clients acknowledge we have earned this unbilled receivable at the time of the original invoice, but we have agreed to defer billing the client for the related services. Unbilled receivables of this nature were approximately $5,800 and $6,431 as of June 30, 2016 and December 31, 2015 , respectively, and are included in accounts receivable on our Consolidated Balance Sheets. We record periodic changes in unbilled receivables and refund liabilities as adjustments to revenue. Recently Issued Accounting Standards In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”) which simplifies several aspects of the accounting for share based compensation. ASU 2016-09 changes several aspects of the accounting for share based payment award transactions, including 1) accounting for income taxes, 2) classification of excess tax benefits on the statement of cash flows, 3) forfeitures, 4) minimum statutory tax withholding requirements and 5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. The guidance is effective for public companies with annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. We are evaluating this new guidance and its impact on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”) which changes the accounting recognition, measurement and disclosure for leases in order to increase transparency. ASU 2016-02 requires lease assets and liabilities to be recognized on the balance sheet and key information about leasing arrangements to be disclosed. The guidance is effective for public companies with annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. Early adoption is permitted. We are evaluating this new guidance and its impact on our consolidated financial statements and related disclosures. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”) which changes the current financial instruments model primarily impacting the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The guidance is effective for public companies with annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. We are evaluating this new guidance and do not believe it will have a material impact on our consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU 2015 ‑17, Balance Sheet Classification of Deferred Taxes , (“ASU 2015 ‑17”) which requires entities with a classified balance sheet to present all deferred tax assets and liabilities as noncurrent. The guidance is effective for public companies with annual and interim periods beginning after December 15, 2016. Early adoption is permitted. We are evaluating this new guidance and its impact on our consolidated balance sheets and related disclosures and expect the adoption of this ASU will reduce our total current assets and net working capital. In April 2015, the FASB issued ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”) which established guidance regarding the accounting for software licenses. ASU 2015-05 is effective for annual reporting periods, including interim periods, beginning after December 15, 2015. We prospectively adopted the provisions of ASU 2015-05 as of January 1, 2016 and have not yet had any material contracts that were impacted by this new guidance. In April 2015, the FASB issued ASU 2015 ‑03, Simplifying the Presentation of Debt and Issuance Costs (“ASU 2015 ‑03”) which establishes guidance to simplify the presentation of debt issuance costs by requiring debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that liability, consistent with debt discounts. Prior to the issuance of ASU 2015-03, debt issuance costs were required to be presented as an asset in the balance sheet. The guidance is effective for annual reporting periods beginning after December 15, 2015, and interim periods within that reporting period. We adopted the provisions of ASU 2015-03 as of January 1, 2016 and prior period amounts have been reclassified to conform to the current period presentation. As of June 30, 2016 and December 31, 2015, $13,658 and $20,975 of debt issuance costs, respectively, were reclassified in the consolidated balance sheet from debt issuance costs, net to long-term debt . The adoption of ASU 2015-03 did not materially impact our consolidated financial position, results of operations or cash flows. In May 2014, the FASB issued ASU No. 2014 ‑09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014 ‑09”) which supersedes existing revenue recognition guidance and provides clarification of principles for recognizing revenue from contracts with customers. The guidance is effective for public companies with annual periods beginning after December 15, 2017 and interim periods within that reporting period. We are evaluating this new guidance, the method of adoption we will take and the impact, if any, on our consolidated financial statements and related disclosures. |
