New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, as a new Topic, Topic 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize 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 Company has adopted this ASU and other related ASUs as of January 1, 2018 (the “adoption date”) using the cumulative effect method which applied to those contracts which were not completed as of the adoption date. Results for reporting periods beginning after the adoption date are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605 as noted above (see Note 3 - Revenues). In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU modify how entities measure equity investments and present changes in the fair value of financial liabilities. Under the new guidance, entities will have to measure equity investments that do not result in consolidation and are not accounted under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the practical expedient exception. An entity may elect to measure an equity security without a readily determinable fair value that does not qualify for the practical expedient to estimate fair value under ASC 820, Fair Value Measurements, and as such these investments may be measured at cost. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company has adopted this ASU on a prospective basis and has determined that investments within the scope of the standard will be recorded at fair value with changes in fair value recognized in earnings which may lead to increased volatility in other expense. In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company expects that the adoption of this ASU will have a material effect on its condensed consolidated balance sheet and disclosures. The Company currently has both capital and operating leases, both domestically and internationally, with varying expiration dates through 2025 in the aggregate amount of $85.9 million for the period ended March 31, 2018. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this standard is not expected to have a material impact on our financial statements and related disclosures. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory. The amendments in this ASU reduce the complexity in the accounting standards by allowing the recognition of current and deferred income taxes for an intra-entity asset transfer, other than inventory, when the transfer occurs. Historically, the income tax consequence was not recognized until the asset was sold to an outside party. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted. The Company has adopted this ASU on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings and has determined that there is no impact on our financial statements and related disclosures as of January 1, 2018. In January 2017, the FASB issued 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendments in this ASU provide a robust framework to use in determining when a set of assets and activities is a business. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted and the standard should be applied prospectively. The Company has adopted this ASU on a prospective basis and has determined that there is no impact on our financial statements and related disclosures. In January 2017, the FASB issued 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this ASU simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test and eliminating the requirement for a reporting unit with a zero or negative carrying amount to perform a qualitative assessment. Instead, under this pronouncement, an entity would perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and would recognize an impairment change for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects will be considered, if applicable. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted and should be adopted on a prospective basis. The Company does not expect the adoption of this ASU to have a material impact on our financial statements and related disclosures. In May 2017, the FASB issued 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. The amendments in this ASU provide guidance about which changes to the terms or conditions of share-based payment award require an entity to apply modification accounting in Topic 718. Specifically, an entity should account for the effects of a modification unless all the following are met: (1) The fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. This ASU is effective for those fiscal years, beginning after December 15, 2017. Early adoption is permitted and should be adopted on a prospective basis. The Company has adopted this ASU on a prospective basis and has determined that there is no impact on our financial statements and related disclosures. In February 2018, the FASB issued 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this ASU allow reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. federal tax legislation, the Tax Cuts and Jobs Act of 2017 (“2017 Tax Act”). Consequently, the amendments eliminate the stranded tax effects resulting from the 2017 Tax Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the 2017 Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates to be included in income from continuing operations is not affected. This ASU is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted and should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the 2017 Tax Act is recognized. The Company is currently evaluating the effect of this ASU on our financial statements and related disclosures. In February 2018, the FASB issued 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU clarify certain aspects of the guidance issued in ASU 2016-01, Financial Instruments - Overall. As is consistent with other clarifying standards, the amendments are not expected to have a significant effect on the current accounting practice. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods beginning after June 15, 2018. Public entities with fiscal years beginning between December 15, 2017 and June 15, 2018 are not required to adopt these amendments until the interim period beginning after June 15, 2018. Early adoption is permitted and should be adopted in conjunction with ASU 2016-01. The Company has adopted this ASU on a prospective basis and have determined that investments within the scope of the standard will be recorded at fair value with changes in fair value recognized in earnings which may lead to increased volatility in other expense. In March 2018, the FASB issued 2018-04, Investments-Debt Securities (Topic 620) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273. The amendments in this ASU update SEC paragraphs pursuant to SEC Staff Accounting Bulletin 117 and better align the interpretive guidance with ASU 2016-01. The Company has adopted this ASU on a prospective basis and has determined that there is no impact on our financial statements and related disclosures. In March 2018, the FASB issued 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (“SAB” or “SAB 118”) (issued in December 2017). The amendments in this ASU add SEC interpretive guidance pursuant to SEC Staff Accounting Bulletin No. 118 which assists registrants address any diversity of views in applying Topic 740 in the reporting period in which the 2017 Tax Cuts and Jobs Act (“2017 Tax Act”) was enacted. Specifically, the ASU provides for a provisional one year measurement period for entities to finalize their accounting for certain income tax effects where (i) the accounting for the income tax effect of the 2017 Tax Act is complete and reported in the 2017 Tax Act’s enactment period; (ii) the accounting for the income tax effect of the 2017 Tax Act is incomplete and reported as provisional amounts based on reasonable estimates (to the extent determinable) subject to adjustments during a limited measurement period until complete; and (iii) accounting for the income tax effect of the 2017 Tax Act is not reasonably estimable (no related provisional amounts are reported in the enactment period) and entities would continue to apply accounting based on tax law provisions in effect prior to the 2017 Tax Act enactment until provisional amounts are reasonably estimable. The Company has adopted this ASU on a prospective basis and has complied with SAB 118 (see Note 10 - Income Taxes).
