Business Combinations The Company applies the provisions of ASC 805, Business Combinations, in the accounting for its acquisitions, which requires recognition of the assets acquired and the liabilities assumed at their acquisition date fair values, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition date fair values of the tangible and identifiable intangible assets acquired and liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, that may be up to 12 months from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with a corresponding adjustment to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, the impact of any subsequent adjustments is included in the consolidated statements of operations. Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance on revenue recognition, which provides for a single, principles-based model for revenue recognition and replaces the existing revenue recognition guidance. The guidance is effective for annual and interim periods beginning on or after December 15, 2017 and will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. It permits the use of either a retrospective or cumulative effect transition method and early adoption is permitted, however not before December 15, 2016. The Company has not yet selected a transition method and is in the process of evaluating the effect this standard will have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued guidance on leases which supersedes the current lease guidance. The core principle requires lessees to recognize the assets and liabilities that arise from nearly all leases on the balance sheet. Accounting applied by lessors will remain largely consistent with previous guidance. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact of this standard on its consolidated financial statements and related disclosures. In March 2016, the FASB issued guidance simplifying the accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. Under the new standard, all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit on the statements of income. An excess income tax benefit arises when the tax deduction of a share-based award for income tax purposes exceeds the compensation cost recognized for financial reporting purposes and, a tax deficiency arises when the compensation cost exceeds the tax deduction. Under current GAAP, excess tax benefits are recognized as additional paid-in capital while tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or on the statements of income. Management adopted the guidance effective December 31, 2016. As a result of the adoption of this guidance, management made an accounting policy election to recognize the effect of forfeitures in compensation cost when they occur, which had an immaterial impact on results of operations and financial position and no impact on cash flows at adoption. In the first quarter of 2017, the Company recorded no income tax expense as a result of the adoption of the new guidance relating to the accounting on the vesting of share-based awards. Excluding the effect of the new guidance, the effective tax rate would have been 33% for certain federal, foreign and state taxes during the six months ended June 30, 2017.
