New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Standards	Recent Accounting Standards Accounting Standards Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases which establishes new accounting and disclosure requirements for leases. This standard will require leases to be recognized on the balance sheet as a right-of-use asset and a lease liability. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. Lessees must apply a modified retrospective transition approach for leases existing at, or entered info after, the beginning of the earliest comparative period presented in the financial statements. The FASB issued additional guidance in July 2018 which provides for an additional (and optional) transition method by allowing entities to apply the transition provisions of the new standard, including its disclosure requirements, at its adoption date instead of at the beginning of the earliest comparative period presented and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We plan to adopt the standard effective January 1, 2019 using the additional transition method. We plan to make an accounting policy election to account for certain short-term leases (with a term of one year or less) using a method similar to the current operating lease model and elect the package of practical expedients. The adoption of this standard is expected to increase the assets and liabilities recorded on our condensed consolidated balance sheet and increase the level of disclosures related to leases. We also expect that adoption of the new standard will require changes to our internal controls to support recognition and disclosure requirements under the new standard. We are currently evaluating our population of leased assets in order to assess the impact of the ASU on our lease portfolio, and designing and implementing new processes and controls. Until this effort is completed, we cannot determine the effect of the ASU on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. The standard will remove step 2 from the goodwill impairment test. Under the ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for public companies for annual reporting periods beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating ASU 2017-04 and the impact of its adoption on our consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. The standard will ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. ASU 2017-12 is effective for public companies for annual reporting periods beginning after December 15, 2018 but early adoption is permitted. We are currently evaluating ASU 2017-12 and the impact of its adoption on our consolidated financial statements.
