Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	In March 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The new guidance is effective for annual periods beginning after December 15, 2017. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In August 2016, the FASB issued guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In February 2016, the FASB issued guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. There continues to be a differentiation between finance leases and operating leases, however lease assets and lease liabilities arising from operating leases should now be recognized in the statement of financial position. New disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. In 2018, the FASB issued several updates to address certain practical expedients, codification improvements, and targeted improvements to the original guidance. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company continues to review the new guidance but expects the new guidance to result in (i) a significant increase in assets due to the recognition of right-of-use assets on the balance sheet and (ii) a significant increase in liabilities due to the recognition of lease liabilities on the balance sheet, however the amount of these increases will not be quantified until closer to the adoption date. The Company’s initial assessment, which is subject to change, is that the new guidance is not expected to have a significant impact on the statement of comprehensive income. In January 2016, the FASB issued guidance that changes how entities measure equity investments and present changes in the fair value of financial liabilities. The new guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value, and as such, these investments may be measured at cost. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted the new guidance in the first quarter of 2018 with no material impact on its financial statements. In May 2014, the FASB issued guidance to clarify the principles for recognizing revenue. The core principle of the guidance is that an entity 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 guidance provides a comprehensive framework for revenue recognition that supersedes current general revenue guidance and most industry-specific guidance. In addition, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. In 2016, the FASB issued several updates to address implementation issues and to clarify guidance for principal versus agent considerations and identifying performance obligations and licensing. The Company adopted the new guidance on January 1, 2018, using the modified retrospective method, with no impact on its financial statements. The cumulative effect of initially applying the new guidance had no impact on the opening balance of retained earnings as of January 1, 2018. There was no impact on the condensed consolidated balance sheet as of June 30, 2018 or on the condensed consolidated statements of comprehensive income for the three and six months ended June 30, 2018. The comparative information has not been restated and continues to be reported under the accounting guidance in effect for that period. The Company does not expect the new guidance to have a material impact on its financial statements in future periods.
