Summary of Significant Accounting Policies The significant accounting policies used in preparing these consolidated financial statements are consistent with the accounting policies described in our Annual Report on Form 10-K for 2015. Recently Adopted Accounting Standards In April 2014, the FASB issued ASU 2014-8, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which includes amendments that change the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under ASU 2014-8, only disposals representing a strategic shift in operations should be presented as discontinued operations. ASU 2014-8 became effective and was adopted for our fiscal year beginning October 1, 2015. The adoption of this standard did not have a significant impact on our consolidated financial statements. Recently Issued Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 requires entities to recognize revenue in a way that depicts 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. ASU 2014-09 will be effective for our fiscal year beginning October 1, 2018, including interim periods within that reporting period, and allows for either full retrospective adoption or modified retrospective adoption, with early adoption permitted on October 1, 2017. We are currently evaluating the impact that ASU 2014-09 will have on our consolidated financial statements. In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2014-12 states that a performance target in a share-based payment that affects vesting and that could be achieved after the requisite service period should be accounted for as a performance condition. ASU 2014-12 will be effective for our fiscal year beginning October 1, 2016, with early adoption permitted. We do not expect the adoption of ASU 2014-12 to have a material impact on our consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern. ASU 2014-15 provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern or to provide related footnote disclosures. ASU 2014-15 will be effective for our fiscal year beginning October 1, 2016, with early adoption permitted. We do not expect the adoption of ASU 2014-15 to have a material impact on our consolidated financial statements. In January 2015, the FASB issued ASU 2015-01, Income Statement—Extraordinary and Unusual Items. ASU 2015-01 eliminates from GAAP the concept of extraordinary items. ASU 2015-01 will be effective for our fiscal year beginning October 1, 2016, with early adoption permitted. We do not expect the adoption of ASU 2015-01 to have a material impact on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Consolidation: Amendments to the Consolidation Analysis. The new standard amends the consolidation guidance in ASC 810 and significantly changes the consolidation analysis required under current generally accepted accounting principles. ASU 2015-02 will be effective for our fiscal year beginning October 1, 2016, with early adoption permitted. We are currently evaluating the impact that ASU 2015-02 will have on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest. ASU 2015-03 simplifies the presentation of debt issuance costs. The amendments in this ASU require 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, consistent with debt discounts. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. This standard permits an entity to defer and present debt issuance costs related to line-of-credit arrangements as an asset and to subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement. These new standards do not affect the recognition and measurement of debt issuance costs. ASU 2015-03 and ASU 2015-15 will be effective for our fiscal year beginning October 1, 2016, with early adoption permitted. We do not expect the adoption of ASU 2015-03 and ASU 2015-15 to have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software. ASU 2015-05 helps entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement by providing guidance as to whether an arrangement includes the sale or license of software. ASU 2015-05 will be effective for our fiscal year beginning October 1, 2016, with early adoption permitted. We are currently evaluating the impact that ASU 2015-05 will have on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330). Under current FASB standards, an entity is required to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. ASU 2015-11 requires an entity to measure inventory within the scope of this update at the lower of cost and net realizable value. Subsequent measurement is unchanged for inventory measured using last-in, first-out (LIFO) or the retail inventory method. ASU 2015-11 will be effective for our fiscal year beginning October 1, 2017, with early adoption permitted. We do not expect the adoption of ASU 2015-11 to have a material impact on our consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations. ASU 2015-16 simplifies the accounting for adjustments made to provisional amounts. The amendments in ASU 2015-16 require that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer is also required to record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, an entity is required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 will be effective for our fiscal year beginning on October 1, 2016, with early adoption permitted. We are currently evaluating the impact that ASU 2015-16 will have on our consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes. ASU 2015-17 requires that deferred income tax liabilities and assets be classified as noncurrent in a classified statement of financial position in order to simplify the presentation of deferred income taxes. ASU 2015-17 will be effective for our fiscal year beginning on October 1, 2017, with early adoption permitted. We expect that ASU 2015-17 will have a financial statement presentation impact only, as all deferred income tax assets and liabilities will be classified as noncurrent on the consolidated balance sheet. In February 2016, the FASB issued ASU 2016-02, Leases. ASU 2016-02 requires lessees to recognize a right of use asset and related lease liability for leases that have lease terms of more than twelve months. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance, with the classifications based on criteria that are similar to those applied under the current lease guidance, without the explicit bright lines. ASU 2016-02 will be effective for our fiscal year beginning on October 1, 2019, with early adoption permitted. We are currently evaluating the impact that ASU 2016-02 will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging: Contingent Put and Call Options in Debt Instruments. ASU 2016-06 clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. ASU 2016-06 will be effective for our fiscal year beginning on October 1, 2017, with early adoption permitted. We are currently evaluating the impact that ASU 2016-06 will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 reduces complexity in the accounting for several aspects of share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification of certain share-based payment transactions on the statement of cash flows. Accounting for Income Taxes: All excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement. Excess tax benefits should be classified along with other income tax cash flows as an operating activity in the statement of cash flows. Forfeitures: An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. Minimum Statutory Tax Withholding Requirements: The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions. Cash paid when directly withholding shares for tax-withholding purposes should be classified as a financing activity in the statement of cash flows. ASU 2016-09 will be effective for our fiscal year beginning on October 1, 2017, with early adoption permitted. We are currently evaluating the impact that ASU 2016-09 will have on our consolidated financial statements.
