Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 20—Recent accounting pronouncements: Adopted In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires unamortized debt issuance costs (or deferred financing costs) to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. Previously, such unamortized debt issue costs were generally presented as a noncurrent asset. ASU 2015-15, issued by the FASB in August 2015, clarified that the scope of ASU 2015-03 does not include deferred financing costs related to revolving credit facilities. The guidance in the new standard is limited to the presentation of debt issuance costs within its scope and does not affect the recognition, measurement or amortization of debt issuance costs. The standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years and is applied on a retrospective basis. Early adoption is permitted, and we have adopted this ASU in this Annual Report. As a result of adopting this ASU, deferred financing costs of $5.1 million at December 31, 2014, previously recognized as an asset, are now classified as a direct deduction from the carrying value of such term loan in our Consolidated Balance Sheet at such date. All of our other deferred financing costs at December 31, 2014 and 2015 (see Note 9) relate to Kronos’ revolving credit facilities in North America and Europe, and continue to be recognized as an asset under the guidance of the ASU. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which eliminates the requirement to separate deferred income tax assets and liabilities into current and noncurrent amounts. Under the ASU all deferred income tax assets and liabilities will be classified as noncurrent. The current requirement that deferred income tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this ASU. This amendment is effective for us beginning in the first quarter of 2017; however early adoption is permitted. In addition, prospective or retrospective application is permitted. We have elected to adopt this ASU retrospectively beginning with this Annual Report and accordingly we have presented all deferred income tax assets and liabilities as noncurrent in our Consolidated Balance Sheets and related Footnotes. At December 31, 2014, we had previously recognized a current deferred income tax asset and liability of $13.4 million and $3.9 million, respectively, and a noncurrent deferred income tax asset and liability of $164.4 million and $412.8 million, respectively. As a result of the retrospective application of this ASU, we no longer have a current deferred income tax asset or liability recognized at December 31, 2014, and the noncurrent deferred income tax asset and liability we now have recognized at December 31, 2014 is $160.9 million and $399.8 million, respectively. See Note 12. Pending Adoption In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). This standard replaces existing revenue recognition guidance, which in many cases was tailored for specific industries, with a uniform accounting standard applicable to all industries and transactions. The new standard, as amended, is currently effective for us beginning with the first quarter of 2018. Entities may elect to adopt ASU No. 2014-09 retrospectively for all periods for all contracts and transactions which occurred during the period (with a few exceptions for practical expediency) or retrospectively with a cumulative effect recognized as of the date of adoption. ASU No. 2014-09 is a fundamental rewriting of existing GAAP with respect to revenue recognition, and we are still evaluating the effect the Standard will have on our Consolidated Financial Statements. We currently expect to adopt the standard in the first quarter of 2018. In addition, we have not yet determined the method we will use to adopt the Standard. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which addresses certain aspects related to the recognition, measurement, presentation and disclosure of financial instruments. The ASU requires equity investments (except for those accounted for under the equity method of accounting or those that result in the consolidation of the investee) to generally be measured at fair value with changes in fair value recognized in net income. The amendment also requires a number of other changes, including among others: simplifying the impairment assessment for equity instruments without readily determinable fair values; eliminating the requirement for public business entities to disclose methods and assumptions used to determine fair value for financial instruments measured at amortized cost; requiring an exit price notion when measuring the fair value of financial instruments for disclosure purposes; and requiring separate presentation of financial assets and liabilities by measurement category and form of asset. The changes indicated above will be effective for us beginning in the first quarter of 2018, with prospective application required, and early adoption is not permitted. The most significant aspect of adopting this ASU will be the requirement to recognize changes in fair value of our available-for-sale marketable equity securities in net income (currently changes in fair value of such securities are recognized in other comprehensive income). In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is a comprehensive rewriting of the lease accounting guidance which aims to increase comparability and transparency with regard to lease transactions. The primary change will be the recognition of lease assets for the right-of –use of the underlying asset and lease liabilities for the obligation to make payments by lessees on the balance sheet for leases currently classified as operating leases. The ASU also requires increased qualitative disclosure about leases in addition to quantitative disclosures currently required. Companies are required to use a modified retrospective approach to adoption with a practical expedient which will allow companies to continue to account for existing leases under the prior guidance unless a lease is modified, other than the requirement to recognize the right-of-use asset and lease liability for all operating leases. The changes indicated above will be effective for us beginning in the first quarter of 2019, with early adoption is permitted. We have not yet evaluated the effect this ASU will have on our Consolidated Financial Statements, but given the material amount of our future minimum payments under non-cancellable operating leases at December 31, 2015 discussed in Note 17, we expect to recognize a material right-of-use lease asset and lease liability upon adoption of the ASU.
