New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued and Adopted Accounting Pronoucements and Regulatory Items	Recently Issued and Adopted Accounting Pronouncements and Regulatory Items New accounting guidance and regulatory items In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments” ("ASU 2016-13"). ASU 2016-13 replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses. The update is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The new standard is effective for fiscal years beginning after December 15, 2019 (i.e. a January 1, 2020 effective date), with early adoption permitted for fiscal years beginning after December 15, 2018. We are evaluating the effect the guidance will have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) ("ASU 2016-09"). ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years (i.e. a January 1, 2017 effective date). We are evaluating the effect the guidance will have on our consolidated financial statements. In February 2016, the FASB issued its new lease accounting guidance in ASU No. 2016-02, Leases (Topic 842). Under the new guidance, lessees will be required to recognize for all leases (with the exception of short-term leases) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis and a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e. a January 1, 2019 effective date). We are evaluating the effect the guidance will have on our consolidated financial statements. 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 amends the guidance in U.S. GAAP on the classification and measurement of financial instruments. Changes to the current guidance primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The new standard is effective for fiscal years and interim periods beginning after December 15, 2017, and upon adoption, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. We are evaluating the effect the guidance will have on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. This new standard changes the criteria by which to measure inventory. Prior to the issuance of this new standard, inventory was measured at the lower of cost or market value. This required three separate data points in order to measure inventory. The three data points were cost, market with a ceiling of net realizable value and market with a floor of net realizable value less a normal profit margin. This amendment eliminates the two data points defining "market" and replaces them with one, net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This amendment does not impact inventory measured using last-in, first-out. We are required to adopt this standard in the first quarter of 2017 and early adoption is permitted. We believe the adoption will not have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. We intend to adopt this standard for interim and annual periods beginning after December 15, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. In 2016, the FASB issued final amendments to clarify the implementation guidance for principal versus agent considerations, identifying performance obligations and the accounting for licenses of intellectual property. We are evaluating the effect that ASU 2014-09 and subsequent amendments will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting. Recently adopted accounting guidance In April 2015, the FASB issued ASU 2015-05, Customer's Accounting for Fees Paid in Cloud Computing Arrangements, which provides guidance to determine when a customer's fees paid in a cloud computing arrangement include a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for a cloud computing arrangement as a service contract. The new standard was effective for annual reporting periods beginning after December 15, 2015 (i.e. January 1, 2016) and entities may elect to adopt the ASU prospectively or retrospectively. We have adopted the standard prospectively. There was no impact on our financial condition, results of operations or cash flows as a result of the adoption of this guidance.
