Accounting Policies [Abstract]
New Accounting Standards	New 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), and the FASB has since issued several amendments to this standard, which clarify the principles for recognizing revenue. This guidance requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard supersedes all existing U.S. GAAP guidance on revenue recognition and is expected to require the use of more judgment and result in additional disclosures. The Company will be required to adopt ASU 2014-09 as of October 1, 2018. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2014-09 on the Company’s financial statements and has not yet determined its method of adoption. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330), Simplifying the Measurement of Inventory. ASU 2015-11 is part of the FASB’s initiative to simplify accounting standards. The guidance requires an entity to recognize inventory within the scope of the standard at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company will be required to adopt ASU 2015-11 as of October 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2015-11 on the Company’s financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is expected to increase transparency and comparability among organizations. The standard requires lessees to reflect most leases on their balance sheet as lease liabilities with a corresponding right-of-use asset, while leaving presentation of lease expense in the statement of income largely unchanged. The standard also eliminates the real-estate specific provisions that exist under current U.S. GAAP and modifies the classification criteria and accounting lessors must apply to sales-type and direct financing leases. The Company will be required to adopt ASU 2016-02 as of October 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-02 on the Company's financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 is part of the FASB’s initiative to simplify accounting standards. The standard requires that all tax effects of share-based payments at settlement (or expiration) be recorded in the income statement at the time the tax effects arise. The standard also clarifies that cash flows resulting from share-based payments be reported as operating activities within the statement of cash flows, permits employers to withhold shares upon settlement of an award to satisfy an employee's tax liability up to the employee's maximum individual tax rate in the relevant jurisdiction without resulting in liability classification of the award and permits entities to make an accounting policy election to estimate or use actual forfeitures when recognizing the expense of share-based compensation. The Company adopted ASU 2016-09 as of October 1, 2016 following a prospective approach for the income tax and earnings per share impacts and a retrospective approach for the cash flow impacts. The adoption of ASU 2016-09 did not have a material impact on the Company's financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The standard requires a change in the measurement approach for credit losses on financial assets measured on an amortized cost basis from an incurred loss method to an expected loss method, thereby eliminating the requirement that a credit loss be considered probable to impact the valuation of a financial asset measured on an amortized cost basis. The standard requires the measurement of expected credit losses to be based on relevant information about past events, including historical experience, current conditions, and a reasonable and supportable forecast that affects the collectibility of the related financial asset. The Company will be required to adopt ASU 2016-13 as of October 1, 2020. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-13 on the Company's financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory. The standard requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset when the transfer occurs as opposed to when the asset is transferred to an outside party as required under current U.S. GAAP. The standard does not apply to intra-entity transfers of inventory, which will continue to follow current U.S. GAAP. The Company will be required to adopt ASU 2016-16 as of October 1, 2018. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-16 on the Company's financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment. The standard simplifies the measurement of goodwill impairment by eliminating the requirement that an entity compute the implied fair value of goodwill based on the fair values of its assets and liabilities to measure impairment. Instead, goodwill impairment will be measured as the difference between the fair value of the reporting unit and the carrying value of the reporting unit. The standard also clarifies the treatment of the income tax effect of tax deductible goodwill when measuring goodwill impairment loss. The Company will be required to adopt ASU 2017-04 as of October 1, 2020. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2017-04 on the Company's financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The standard requires that an entity report the service cost component of net periodic pension and postretirement cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The remaining components of net benefit costs are required to be presented in the income statement separately from the service component and outside a subtotal of income from operations, if one is presented. The amendment further allows only the service cost component of net periodic pension and postretirement costs to be eligible for capitalization, when applicable. The Company will be required to adopt ASU 2017-07 as of October 1, 2018. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2017-07 on the Company's financial statements.
