Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Revenue from Contracts with Customers— In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers Topic 606 (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. Subsequent to issuing ASU No. 2014-09, the FASB issued the following amendments concerning the adoption and clarification of ASU No. 2014-09. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delayed the effective date of the new standard for the Company from October 1, 2017 to October 1, 2018. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which further clarifies the implementation guidance on principal versus agent considerations. The new guidance requires either a retrospective or a modified retrospective approach to adoption. In April 2016, the FASB issued ASU No. 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies the identification of the performance obligations and licensing implementation guidance, while retaining the related principals of those areas. In May 2016, the FASB issued ASU No. 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides clarification on assessing the collectability criterion, presentation of sales taxes, measurement date for noncash consideration and completed contracts at transition. The Company is evaluating the method of adoption and the potential impact that these ASUs will have on our financial position, results of operations, cash flows, and liquidity. Imputation of Interest— In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The new standard 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, consistent with debt discounts. In August 2015, the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarified that debt issuance costs related to line-of-credit arrangements can be presented in the balance sheet as an asset and amortized over the term of the line-of-credit arrangement. The standard is to be applied retrospectively and was effective for the Company beginning on October 1, 2016. As of September 30, 2016 and September 30, 2015, the Company had deferred financing costs of $5.9 million and $7.5 million, respectively, within other assets. These costs will be presented as a deduction from the carrying amount of the Company's debt balance beginning on October 1, 2016. Business Combinations— In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The new standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined and sets forth new disclosure requirements related to the adjustments. The standard is to be applied prospectively and was effective for the Company beginning on October 1, 2016. Although the impact of applying this standard to prior acquisitions would have been immaterial, the standard could have a significant impact on the accounting for future business combinations. Income Taxes— In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The new standard requires that deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. The amendments in this update apply to all entities that present a classified statement of financial position and is to be applied either prospectively or retrospectively. The update will be effective for the Company beginning on October 1, 2017. As of September 30, 2016 and September 30, 2015, the Company had current deferred tax assets, net of current deferred tax liabilities, of $18.0 million and $19.6 million, respectively. Leases— In February 2016, the FASB issued ASU No. 2016-02-Leases (Topic 842). The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The standard is to be applied using a modified retrospective approach and is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements but expects that the adoption of ASU No. 2016-02 will result in an increase to its long-term assets and liabilities on the consolidated balance sheet. Stock Compensation— In March 2016, the FASB issued ASU No. 2016-09-Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The areas for simplification in this update involve several aspects of the 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. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements. Statement of Cash Flows— In August 2016, the FASB issued ASU No. 2016-15- Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The new standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements.
