New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING STANDARDS	*Accounting standards adopted* In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09 (“ASU 2016-09”), Compensation—Stock Compensation, (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 requires excess tax benefits and tax deficiencies, which arise due to differences between the measure of compensation expense and the amount deductible for tax purposes, to be recorded directly through the statement of operations when awards vest or are settled. In addition, cash flows related to excess tax benefits will no longer be classified separately as a financing activity apart from other tax cash flows. We elected to early adopt the new guidance for the year ended December 31, 2016. Upon adoption using the modified retrospective transition method, we recorded a cumulative effect adjustment to recognize previously unrecognized excess tax benefits which increased deferred tax assets and reduced accumulated deficit by $7.1 million. The current net tax benefit for 2016 resulting from adoption of the new guidance is approximately $400,000 and is reflected in our tax provision. *Accounting standards not yet adopted* In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, (Topic 606). ASU 2014-09 requires an entity to recognize as revenue the amount that reflects the consideration to which it expects to be entitled in exchange for goods or services as it transfers control to its customers. It also requires more detailed disclosures to enable users of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company’s current revenue recognition policies for our most significant revenue streams, materially comply with the amended guidance. The primary change for healthcare providers under the new guidance is the requirement to report the allowance for uncollectible accounts associated with patient responsibility amounts as a reduction in net revenue as opposed to bad debt expense as a component of operating expenses. The new standard supersedes most current revenue guidance, including industry-specific guidance, and may be applied retrospectively with cumulative effect recognized in retained earnings as of the date of adoption (modified retrospective method). The guidance became effective for the Company on January 1, 2018 and the Company adopted the new standard using the modified retrospective approach. As part of adopting the standard, the Company identified revenue streams of like contracts to allow for ease of implementation. The Company used primarily a portfolio approach to apply the new model to classes of customers with similar characteristics. The impact of adopting the new standard on our total revenue; and income from operations is not material. The immaterial impact of adopting Topic 606 primarily relates to recognizing certain credit and collection issues not known at the date of service, including bankruptcy, in the provision for uncollectible accounts included in expenses on the consolidated statement of operations, which previously were netted against service revenue. In addition, the number of our performance obligations under the new standard is not materially different from our contract segments under the existing standard. Lastly, the accounting for the estimate of variable consideration is not materially different compared to our current practice. As such, the adoption of this guidance is not expected to have a material impact on our Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, (Topic 842): Amendments to the FASB Accounting Standards Codification. ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The amendments in this update are effective for fiscal years (and interim reporting periods within fiscal years) beginning after December 15, 2018. Early adoption of the amendments is permitted for all entities. We are currently evaluating the impact this guidance will have on our consolidated financial statements, but expect this adoption will result in a significant increase in the assets and liabilities related to our leased properties and equipment. In February 2018, the FASB issued ASU No. 2018-02 (“ASU 2018-02”), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-02 allows for the reclassification of certain income tax effects related to the Tax Cuts and Jobs Act between “Accumulated other comprehensive income” and “Retained earnings.” This ASU relates to the requirement that adjustments to deferred tax liabilities and assets related to a change in tax laws or rates to be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income” (rather than in “Income from continuing operations”). ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. Adoption of this ASU is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax laws or rates were recognized. We are evaluating the effect of this guidance. In January 2017, the FASB issued ASU No. 2017-04 (“ASU 2017-04”), Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of the current goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on the current Step 1). ASU 2017-04 is effective for annual and any interim impairment tests for periods beginning after December 15, 2019, with early adoption permitted. We are evaluating the effect of this guidance. In January 2017, the FASB issued ASU No. 2017-01 (“ASU 2017-01”), Clarifying the Definition of a Business. ASU 2017-01 changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is considered a business. ASU 2017-01 is effective for annual periods beginning after December 31, 2017 including interim periods within those periods. There was no material impact on our financial statements.
