Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2.RECENT ACCOUNTING PRONOUNCEMENTS There have been no material changes to our significant accounting policies and estimates from the information provided in Part II, Item 8, “Financial Statements and Supplementary Data” in our 2016 Form 10-K. Recently Adopted Accounting Pronouncements On January 1, 2017, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. As required by the standard, excess tax benefits and deficiencies recognized on share-based compensation expense are recorded in the consolidated statement of comprehensive income as a component of income tax expense. Previously, these amounts were recorded as a component of additional paid-in capital on the consolidated balance sheet. We elected to apply the change in presentation to the consolidated statement of cash flows prospectively to classify excess tax benefits as an operating activity rather than a financing activity. Upon adoption, we determined that we did not have previously unrecognized excess tax benefits to be recognized on a modified retrospective transition method as an adjustment to retained earnings. We will continue to classify cash paid related to shares withheld to satisfy tax-withholding requirements as a financing activity, as required by the standard. We made a policy election to account for forfeitures as they occur, rather than estimating the expected forfeitures over the course of the vesting period. The cumulative-effect adjustment to retained earnings as of the date of adoption was $0.4 million, with a reduction in the related deferred tax liability of $0.3 million. ASU 2016-09 also requires that excess tax benefits and deficiencies be prospectively excluded from assumed future proceeds in the calculation of diluted weighted average shares when calculating diluted earnings per share utilizing the treasury stock method. We applied this change prospectively, and it did not have a material impact on our unaudited consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment (Topic 350), which simplifies the goodwill impairment test by eliminating step 2, which is the step requiring companies to perform a hypothetical purchase price allocation to measure goodwill. Instead, under the new standard, impairment will be measured using the difference between the fair value of a reporting unit with its carrying amount. Any impairment charge will be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value, taking into consideration income tax effects from any deductible goodwill on the carrying amount of the reporting unit. This standard will be effective for public companies for annual and interim periods beginning after December 15, 2019 and will be applied prospectively. Early adoption is permitted on impairment tests performed on testing dates after January 1, 2017. The Company early adopted this standard during the first quarter of 2017; the adoption did not have a material effect on our unaudited consolidated financial statements or related disclosures. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This update is intended to improve the financial reporting requirements for revenue from contracts with customers by providing a principle-based approach. The core principle of the standard is that revenue should be recognized when the transfer of promised goods or services is made in an amount that the entity expects to be entitled to in exchange for the transfer of goods and services. The update also requires disclosures enabling users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has recently issued several amendments to the standard, including clarification on principal versus agent considerations, accounting for licenses of intellectual property and identifying performance obligations. Although early adoption as of the original effective date of January 1, 2017 is permitted, we have elected to adopt the guidance effective January 1, 2018. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). We currently anticipate that the largest impact to us of adopting the guidance will occur with contracts which include variable consideration, and therefore, anticipate using the cumulative catch-up transition method of adoption. We will continue to evaluate the impact of our pending adoption of this guidance to our consolidated financial statements, but our preliminary assessments of the impact of our adoption of this guidance are subject to change. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update amends the requirements for assets and liabilities recognized for all leases longer than twelve months. Lessees will be required to recognize a lease liability measured on a discounted basis, which is the lessee’s obligation to make lease payments arising from the lease, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. This standard will be effective for financial statements issued by public companies for the annual and interim periods beginning after December 15, 2018. Early adoption of the standard is permitted. The standard will require a modified retrospective approach for leases existing at or entered into after the beginning of the earliest comparative period presented. We are currently evaluating the potential impact of our adoption of this guidance on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flow (Topic 230). This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The update provides new guidance regarding the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitized transactions, and separately identifiable cash flows and application of the predominance principle. This standard will be effective for financial statements issued by public companies for the annual and interim periods beginning after December 15, 2017. Early adoption of the standard is permitted. The standard will be applied in a retrospective approach for each period presented. We have completed an initial evaluation of the impact of our adoption of this standard and have determined that the manner in which we classify our contingent acquisition liability payments in the consolidated statement of cash flows will change. Based on our initial evaluation, our adoption of this standard may require an immaterial reclassification of a portion of the payments previously reported as financing activities for comparative periods in the statement of cash flows within our consolidated financial statements issued on or after January 1, 2018. Under this guidance, portions of these payments will be reclassified from financing activities to operating activities. We will continue to evaluate the potential impact of our adoption of this guidance on our consolidated financial statements, but our preliminary assessments of the impact of our adoption of this guidance are subject to change. In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business (Topic 805), which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This standard will be effective for public companies for annual and interim periods beginning after December 15, 2017. Early adoption is permitted effective for transactions not yet reported in financial statements issued or made available for issuance. We are currently evaluating the potential impact of this guidance on our consolidated financial statements.
