Accounting Changes And Error Corrections [Abstract]
Recent Accounting Standards	(12) Recent Accounting Standards On January 1, 2018, we adopted ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments, which adds or clarifies guidance of the classification of certain cash receipts and payments in the statement of cash flows, and ASU 2016-18, Restricted Cash, which requires an entity to show the changes in total cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. We adopted these ASUs by applying a retrospective transition method which requires a restatement of our Consolidated Statement of Cash Flows for all periods presented. In February, 2016, the FASB issued ASU 2016-02, “Leases (Topic 842): Amendments to the FASB Accounting Standards Codification (“Update 2016-02”), which requires an entity to recognize lease assets and lease liabilities on the balance sheet and to disclose key qualitative and quantitative information about the entity’s leasing arrangements. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842) - Targeted Improvements (“ASU 2018-11”), which provides an additional transition method allowing entities to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. This update is effective for annual reporting periods beginning after December 15, 2018 with early adoption permitted. While we continue to evaluate other practical expedients available under the guidance, we expect to elect the package of practical expedients permitted under the transition guidance within ASU 2016-02 to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs and, therefore, do not anticipate a material impact on our consolidated statements of income. While we are continuing to assess the effects of adoption, we currently believe the most significant changes relate to the recognition of significant right-of-use assets and lease liabilities on our consolidated balance sheet as a result of our operating lease obligations, as well as the impact of new disclosure requirements. Operating lease expense will still be recognized on a straight-line basis over the remaining life of the lease within lease and rental expense in the consolidated statements of income. We plan to adopt ASU 2016-02 on January 1, 2019 and anticipate using the optional transition method in ASU 2018-11. Under this method, we would not adjust our comparative period financial statements for the effects of the new standard or make the new required lease disclosures for periods prior to the effective date. In January, 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment” (“ASU 2017-04”), which removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the annual and interim periods beginning January 1, 2020 with early adoption permitted, and applied prospectively. We do not expect ASU 2017-04 to have a material impact on our financial statements. In August, 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities", which amends the accounting and presentation of certain hedging activities outlined in ASC 815 and is intended to more accurately present economic results of hedging activities. This update is effective for annual reporting periods beginning after December 15, 2018 with early adoption permitted. The adoption is required prospectively with a cumulative-effect adjustment. We are currently evaluating the impact of this ASU on our financial statements. In February, 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. This update is effective for annual reporting periods beginning after December 15, 2018 with early adoption permitted. We are currently evaluating the impact of this ASU on our financial statements. From time to time, new accounting guidance is issued by the FASB or other standard setting bodies that is adopted by the Company as of the effective date or, in some cases where early adoption is permitted, in advance of the effective date. The Company has assessed the recently issued guidance that is not yet effective and, unless otherwise indicated above, believes the new guidance will not have a material impact on our results of operations, cash flows or financial position.
