Accounting Changes And Error Corrections [Abstract]
Recently Issued Accounting Standards	(4) Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). This guidance will supersede most current revenue recognition guidance, including industry-specific guidance. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The guidance, as agreed to by the FASB, is effective for the interim and annual periods beginning on or after December 15, 2017. Early adoption is permitted on January 1, 2017. The guidance permits the use of either a retrospective or cumulative effect transition method. We have not yet selected a transition method and are currently evaluating the impact of the guidance on the consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Topic 835-30). This guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This guidance is effective for fiscal years and interim periods beginning after December 15, 2015, and requires retrospective application. We adopted this guidance as of April 3, 2016, using retrospective application. Upon adoption of this guidance, the debt and total assets presented on our consolidated balance sheet were reduced by net debt issuance costs, which totaled $19.6 million as of December 31, 2015. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes (Subtopic 740-10). ASU 2015-17 simplifies the presentation of deferred income taxes by eliminating the requirement for companies to present deferred tax liabilities and assets as current and non-current on the Consolidated Balance Sheets. Instead, companies will be required to classify all deferred tax assets and liabilities as non-current. This guidance is effective for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. We elected to early adopt ASU 2015-17 prospectively, on December 31, 2015. The adoption of ASU 2015-17 did not have a material impact on our consolidated financial position, and had no impact on our results of operations or cash flows. No prior periods were retrospectively adjusted. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The primary focus of the standard addresses the accounting of lessees. It requires all lessees to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease) on the balance sheet. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. Operating leases will result in straight-line expense while finance leases will result in depreciation expense recorded on the right-of-use asset and interest expense recorded on the lease liability. Quantitative and qualitative disclosures are required to provide insight into the extent of revenue and expense recognized and expected to be recognized from leasing arrangements. This guidance becomes effective January 1, 2019. Early adoption is permitted. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718). This guidance updates several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Specific changes include that all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) should be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity would also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits would be classified along with other income tax cash flows as an operating activity in the consolidated statement of cash flows. Also, an entity can make an accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. This ASU also amends guidance for the calculation of earnings per share under the treasury stock method by removing excess tax benefits as an assumed proceed from the exercise of options. This guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any interim or annual period. We did not early adopt this guidance and are currently evaluating the impact on the consolidated financial statements.
