New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	Accounting Standards Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases which establishes new accounting and disclosure requirements for leases. This standard will require leases to be recognized on the balance sheet as a right-of-use asset and a lease liability. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. Lessees must apply a modified retrospective transition approach for leases existing at, or entered info after, the beginning of the earliest comparative period presented in the financial statements. The FASB issued additional guidance in July 2018 which provides for an additional (and optional) transition method by allowing entities to apply the transition provisions of the new standard, including its disclosure requirements, at its adoption date instead of at the beginning of the earliest comparative period presented and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We plan to adopt the standard effective January 1, 2019 using the additional transition method. We plan to make an accounting policy election to account for certain short-term leases (with a term of one year or less) using a method similar to the current operating lease model and elect the package of practical expedients. The adoption of this standard is expected to increase the assets and liabilities recorded on our condensed consolidated balance sheet and increase the level of disclosures related to leases. We also expect that adoption of the new standard will require changes to our internal controls to support recognition and disclosure requirements under the new standard. We are currently evaluating our population of leased assets in order to assess the impact of the ASU on our lease portfolio, and designing and implementing new processes and controls. Until this effort is completed, we cannot determine the effect of the ASU on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. The standard will remove step 2 from the goodwill impairment test. Under the ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for public companies for annual reporting periods beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating ASU 2017-04 and the impact of its adoption on our consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. The standard will ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. ASU 2017-12 is effective for public companies for annual reporting periods beginning after December 15, 2018 but early adoption is permitted. We are currently evaluating ASU 2017-12 and the impact of its adoption on our consolidated financial statements. Accounting Standard Adopted In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. ASU 2018-15 amends current guidance to align the accounting for costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing costs associated with developing or obtaining internal-use software. Capitalized implementation costs must be expensed over the term of the hosting arrangement and presented in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement. Both internal and external costs for activities to develop or obtain software that allow for access to or conversion of old data by new system, as well as coding and testing during the application development stage are capitalizable. Training activities and data conversion activities will continue to be expensed as incurred. ASU 2018-15 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted, and the Company early adopted the ASU during the third quarter of 2018, effective July 1, 2018 on a prospective basis. In connection with the adoption of ASU 2018-15, the Company capitalized $0.9 million of implementation costs relating to a new enterprise resource planning (ERP) system that went live in October 2018. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Accounting Standards Codification (ASC) Topic 606), which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. We adopted ASC Topic 606 on January 1, 2018 using the modified retrospective method. Under this transition method, we applied the new standard to contracts that were not completed as of the adoption date and recognized a cumulative effect adjustment which reduced retained earnings by $0.4 million on January 1, 2018. The comparative prior period information has not been restated and continues to be presented according to accounting standards in effect for those periods. The primary impact of ASU No. 2014-09 on our financial statements is a change in revenue recognition on a small portion of our contracts from a proportional performance method, where revenue was previously recognized over contract performance, to a point in time method, where revenue is now recognized upon completion of our performance obligations. While we don't believe the adoption of ASU 2014-09 will materially impact our overall financial statements, the change in timing of revenue recognition on certain contracts could result in quarter to quarter fluctuations in revenue. See Note 3 for further details regarding our revenue recognition accounting policies and other required disclosures.
