Accounting Changes and Error Corrections [Abstract]
New accounting standards	New accounting standards On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), 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. In 2015, 2016 and 2017, the FASB issued ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-11, ASU 2016-12, and ASU 2017-10, each of which amends the guidance in ASU 2014-09. These ASUs replaced most existing revenue recognition guidance in GAAP. The Company adopted these ASUs beginning January 1, 2018. See Note 2 for further details. 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. In February 2018, the FASB issued ASU 2018-03, which provides various related technical corrections and improvements. The Company adopted these ASUs beginning January 1, 2018. See Note 5 for further details. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this ASU revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for substantially all leases with lease terms in excess of twelve months. The new lease guidance also simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. In July 2018, the FASB issued ASU No. 2018-10, Codification Amendments to Topic 842, and ASU No. 2018-11, which include targeted improvements to the guidance issued in ASU 2016-02. The amendments in these ASUs are effective for the Company beginning on January 1, 2019 and are to be applied through a modified retrospective transition approach for leases existing at, or entered into after, either at the beginning of the earliest comparative period presented in the financial statements or at the adoption date with a cumulative effect adjustment. Early adoption is permitted. The Company has assembled an internal cross-functional lease task force that meets regularly to discuss and evaluate the current lease portfolio and related systems, processes, controls and policy changes necessary. The Company has made progress in gathering the necessary data elements for the lease population and a system provider has been selected, with system configuration and implementation underway. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and believes it will have a material impact on its consolidated balance sheet but will not have a material impact on its results of operations or liquidity. The Company expects to adopt these ASUs by applying the new guidance on January 1, 2019 and recognizing a cumulative effect adjustment. The Company is currently planning on electing the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs. The Company continues to evaluate other practical expedients available under the guidance as well as the effect that the implementation of this guidance will have on its consolidated financial statements, related disclosures and controls, and ongoing business policies and processes. 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 amendments in this ASU clarify how certain cash receipts and cash payments should be classified on the statement of cash flows. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted cash. The amendments in this ASU require that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The adoption of these ASUs did not have a material impact on the Company’s consolidated financial statements when adopted on January 1, 2018. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The amendments in this ASU allow entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The current guidance does not allow recognition until the asset has been sold to an outside party. The amendments in this ASU are effective for the Company beginning on January 1, 2018 and are to be applied on a modified retrospective basis. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements when adopted on January 1, 2018. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU 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. The amendments in the new ASU are effective for the Company on January 1, 2019 and are to be applied prospectively. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements when adopted on January 1, 2019. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows for the reclassification of certain income tax effects related to the 2017 Tax Act between “Accumulated other comprehensive income” and “Retained earnings.” This ASU relates to the requirement that adjustments to deferred tax liabilities and assets related to a change in tax laws or rates be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income” (rather than in “Income from continuing operations”). The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The Company elected to early adopt this ASU on January 1, 2018 and applied the change in the period of adoption. The adoption of this ASU resulted in the reclassification of an immaterial amount of deferred tax effects from accumulated other comprehensive income to retained earnings via a cumulative change in accounting principle effective January 1, 2018. See Note 14 for more details. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework -Changes to the Disclosure Requirements for Fair Value Measurement. The applicable amendments in this ASU remove requirements for disclosures concerning transfers between fair value measurement Levels 1, 2 and 3 and disclosures concerning valuation processes for Level 3 fair value measurements. The applicable amendments in this ASU also add a requirement to separately disclose the changes in unrealized gains and losses included in other comprehensive income for the reporting period for Level 3 items measured at fair value on a recurring basis, and require disclosure of the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU are effective for the Company beginning on January 1, 2020 and its new requirements are to be applied on a prospective basis. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
