Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently adopted accounting pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued updated guidance for accounting for employee share based payments. 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 Company has adopted this guidance with the following effects on its Consolidated Financial Statements: - All excess tax benefits and tax deficiencies should be recognized as income tax expense. This guidance was adopted on a modified retrospective basis with a $4.2 million cumulative impact on retained earnings and will be applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements after the date of adoption. Additionally, for purposes of the diluted share count calculation for the Company's earnings per share, which is performed under the treasury stock method, the Company is no longer including excess tax benefits. - Excess tax benefits should be classified along with other income tax cash flows as an operating activity. This guidance was adopted with no impact on the Consolidated Statement of Cash Flows and will be applied prospectively to all excess tax benefits resulting from settlements after the date of adoption. - An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. The Company has elected to account for forfeitures when they occur. - The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions. The Company has adopted this guidance with no impact on its Consolidated Financial Statements given that withholdings are calculated using actual statutory withholding tables. - Cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity. The Company adopted this guidance with no impact on its Consolidated Statement of Cash Flows as the Company currently classifies statutory withholding taxes paid on share-based compensation as a financing activity. In January 2017, the FASB issued updated guidance to simplify the test for goodwill impairment. The amendments in this Update modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The Company selected to early adopt this guidance for the goodwill impairment test performed as part of the reallocation of goodwill in connection with the Company's change in operating segments. Recently issued accounting pronouncements The FASB has issued the following accounting pronouncements and guidance relevant to the Company’s operations: In February 2017, the FASB issued updated guidance clarifying the scope of asset derecognition guidance and accounting for partial sales of nonfinancial assets. The amendments in this Update clarify the scope of the FASB’s recently established guidance on nonfinancial asset derecognition (ASC 610-20) as well as the accounting for partial sales of nonfinancial assets. This Update conforms the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. The amendments in this Update are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements, if any. In May 2017, the FASB issued updated guidance to clarify the scope of modifications under share based compensation accounting. The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments in this update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. The Company will apply this guidance to future changes in terms and conditions of share-based payment awards. In August 2017, the FASB issued updated guidance to improve accounting for hedging activities. The amendments in this update better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments in this update require an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported and also include certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early application is permitted in any interim period after issuance of the update. All transition requirements and elections should be applied to hedging relationships existing (that is, hedging relationships in which the hedging instrument has not expired, been sold, terminated, or exercised or the entity has not removed the designation of the hedging relationship) on the date of adoption. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption (that is, the initial application date). The Company is currently evaluating the impact the adoption of this guidance will have on its financial statements. Accounting pronouncements issued prior to 2017 and not yet adopted During 2014, the FASB issued new guidance for 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 and also includes changes in the accounting for customer contract acquisition costs and fulfillment costs. During 2016, the FASB issued several additional updates that amended the proposed guidance. These new standards will replace most existing revenue recognition guidance in GAAP, and are effective for public reporting companies for interim and annual periods beginning after December 15, 2017. The standards permit two methods of adoption: retrospectively to each prior reporting period presented (the full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective transition method). Management has determined to apply the new standards retrospectively with the cumulative effect recognized at the date of initial application, January 1, 2018. Management has completed its quantitative impact analysis and detailed contract reviews in order to determine the new standards impact on the Company’s consolidated results of operations and financial condition. Based on work performed, Management believes the new standards will have an impact in the following areas: - Where the Company charges upfront fees for implementation or set-up activities, including fees charged in preproduction periods, the period over which these fees will be recognized may in some cases be shorter than our current practice. - The Company may have certain contracts with an implicit price concession. The Company may enter into such implicit price concessions subsequent to the contract inception with the expectation of accepting less than the contractual amount of consideration in exchange for goods or services. Price concessions reduce the transaction price to reflect the consideration that the Company expects to be entitled to after the concession is provided. - Revenue for certain professional services that are recognized upon completion of the services were evaluated under the new standards and determined that the revenue should be recognized over time. - Required enhancements to current disclosures around revenue recognition. Based on the quantitative impact analysis, the transition adjustment calculation upon adoption of the standards was not material to retained earnings. The Company has implemented appropriate changes to its business processes, systems and controls to support recognition and disclosures under the new standards. During 2016, the FASB issued updated guidance for financial reporting about leasing transactions. The amendments in this Update require a lessee to recognize assets and liabilities for leases with lease terms of more than 12 months. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. In addition, the Update requires that both financing and operating leases be recognized on the balance sheet. The guidance also requires disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative requirements, providing additional information about the amounts recorded in the financial statements. The Company expects to adopt this guidance in the period required by the Update and continues to evaluate the impact that this Update will have on its consolidated financial statements. During 2016, the FASB issued updated guidance for the measurement of credit losses on financial instruments. The amendments in this Update require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset or assets to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The Company expects to adopt this guidance in the fiscal period required by this Update and continues to evaluate if the adoption will have an impact on the consolidated financial statements.
