In March 2018, the FASB issued ASU 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SEC Update), Income Taxes (Topic 740). ASU 2018-05 provides guidance regarding the recording of tax impacts where uncertainty exists, in the period of adoption of the 2017 U.S. Tax Cuts and Jobs Act (the “2017 Tax Act”), which allowed companies to reflect provisional amounts for those specific income tax effects of the 2017 Tax Act for which the accounting under ASC Topic 740 is incomplete but for which a reasonable estimate could be determined. During the six months ended June 30, 2018, the Company has not recognized any material changes to the provisional amounts recorded in our 2017 Annual Report on Form 10-K in connection with the 2017 Tax Act.

Accounting Standards Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases ("ASC 842"), which supersedes existing lease guidance. Under ASC 842, we will be required to record right-of-use assets and corresponding lease liabilities on the balance sheet. Previously, there was no requirement to recognize an asset or liability on the balance sheet for an operating lease. ASC 842 also requires disclosure of key information about leasing arrangements. This guidance is effective beginning January 1, 2019 using a modified retrospective approach for each prior reporting period presented. In January 2018, the FASB issued an exposure draft of the proposed ASU, Leases (Topic 842): Targeted Improvements. The proposed ASU provides an alternative transition method of adoption, permitting the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company's implementation plan is under way and includes an information system and business process change to accumulate the appropriate data in order to calculate and record the recognition of right-of-use assets, lease liabilities and the related expense recognition. We are creating an inventory of our existing portfolio of leases and continue to review other contracts to determine if they contain leases as defined by ASC 842. Our existing portfolio of leases is primarily composed of operating leases related to our offices. While this assessment continues, we have not yet determined the effect of ASC 842 on our Condensed Consolidated Balance Sheets. We do not expect that the adoption of ASC 842 will have a material impact on our results of operations or cash flow presentation.
