Summary of Significant Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Discontinued Operations and Disclosures of Disposals of Components of an Entity In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”), which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of or is classified as held for sale and “represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results.” The new standard applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The amendment is effective for annual reporting periods beginning after December 15, 2014. We adopted the new standard as of January 1, 2015. The adoption of the new standard did not change the manner in which we present discontinued operations in our consolidated financial statements. Revenue from Contracts with Customers In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. Under the new guidance, “an entity recognizes 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 new standard provides entities the option of using either a full retrospective or a modified approach to adopt the guidance. The new standard is effective for annual reporting periods beginning after December 15, 2016, which for us is January 1, 2017, and interim periods within those annual periods. In July 2015, the FASB agreed to defer by one year the effective date of the new standard. The new standard is now effective for annual reporting periods beginning after December 15, 2017, which for us is January 1, 2018, and interim periods within those annual periods. Early adoption is now permitted, but not before the original effective date, which for us is January 1, 2017. We are currently evaluating the impact, if any, this new standard will have on our consolidated financial statements, when we will adopt the new standard, and the method of adoption. Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), which provides guidance on determining when and how to disclose going concern uncertainties in the consolidated financial statements. Under the new guidance, management would be required to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. Certain disclosures must be provided if “conditions or events raise substantial doubt about an entity’s ability to continue as a going concern.” The new standard is effective for annual reporting periods ending after December 15, 2016, which for us is December 31, 2016, and interim periods thereafter. Early adoption is permitted. Upon adoption, although we do not anticipate that the new standard will have an impact on our disclosures, we will consider the new standard when conducting our interim and annual assessments of our ability to continue as a going concern. Income Statement - Extraordinary and Unusual Items In January 2015, the FASB issued ASU 2015-01, Income Statement – Extraordinary and Unusual Items, (“ASU 2015-01”), which removes the concept of extraordinary items from U.S. GAAP. Under the existing guidance, an entity is required to separately disclose extraordinary items, net of tax, in the income statement after income from continuing operations if an event or transaction is both unusual and occurs infrequently. This separate, net-of-tax presentation will no longer be allowed. The existing requirement to separately disclose events or transactions that are unusual or occur infrequently on a pre-tax basis within continuing operations in the income statement has been retained. Similarly, the new guidance requires that items that are both unusual and infrequent be presented separately within continuing operations in the income statement. The new standard is effective for periods beginning after December 15, 2015, which for us is January 1, 2016. Early adoption is permitted, but only as of the beginning of the fiscal year of adoption. Upon adoption, we will present transactions that are both unusual and infrequent, if any, on a pre-tax basis within continuing operations in the income statement. Simplifying the Presentation of Debt Issuance Costs In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, (“ASU 2015-03”), which requires that debt issuance costs be presented in the balance sheet as a direct deduction of the carrying value of the associated debt liability. Under the existing guidance, debt issuance costs are required to be presented in the balance sheet as a deferred charge (i.e., an asset). The new standard is effective for periods beginning after December 15, 2015, which for us is January 1, 2016. Early adoption is permitted for financial statements that have not been previously issued. The new standard should be applied retrospectively to all periods presented in the financial statements. In June 2015, at the Emerging Issues Task Force meeting, the FASB clarified that ASU 2015-03 does not address debt issuance costs related to revolving credit debt arrangements. In connection therewith, at the June 2015 meeting, the SEC staff announced that it would not object to the presentation of issuance costs related to revolving debt arrangements as an asset that is amortized over the term of the arrangement. In August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which amended ASU 2015-03 to incorporate the conclusions reached by the SEC staff at its June 2015 Emerging Issues Task Force meeting. Currently, we present debt financing costs related to our revolving credit facility debt as an asset in our consolidated balance sheets. Upon adoption, we will continue to present debt financing costs related to our revolving credit facility debt as an asset in our consolidated balance sheets. Simplifying the Accounting for Measurement-Period Adjustments In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, (“ASU 2015-16”), which eliminates the requirement to restate prior period financial statements for measurement period adjustments related to business acquisitions. The new guidance requires that the cumulative impact of a measurement period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified. In addition, ASU 2015-16 requires that companies present separately on the face of the income statement, or disclose in the notes, the portion of the adjustment recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment had been recognized as of the acquisition date. The new standard is effective for periods beginning after December 15, 2015, which for us is January 1, 2016. The new standard should be applied prospectively to measurement period adjustments that occur after the effective date. Early adoption is permitted. Upon adoption, we will apply the new standard to measurement period adjustments related to business acquisitions.
