Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Accounting Pronouncements Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” a new comprehensive revenue recognition standard that supersedes previous guidance under U.S. GAAP. The core principle of the new standard 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 company expects to be entitled in exchange for those goods or services. Our implementation efforts included the identification of revenue within the scope of the standard, the evaluation of revenue contracts under the guidance, and assessing the impacts of the new standard on our financial statements. The Company adopted the new standard as of January 1, 2018 using the modified retrospective method of adoption. This method allows companies to record a one-time adjustment to beginning retained earnings as of January 1, 2018 for the cumulative effect that the standard will have on open contracts at the date of adoption. During our implementation, we identified certain contracts that now require over time recognition under the new standard, either as goods are manufactured or services are performed, rather than at the time of shipment or completion as we did under previous guidance. Upon adoption, we recorded previously unrecognized revenue of $13.6 million, resulting in a cumulative-effect adjustment of $2.6 million to our 2018 beginning retained earnings. See Note 3 for further details. In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The Company adopted this standard effective January 1, 2018. Other components of net pension income includes all amounts other than the service cost component of pension income.

This resulted in the reclassification of the following amounts from previously-reported Selling, general and administrative expenses for the three-months ended March 31, 2017: $1.7 million of net pension income to Other components of net pension income and $0.5 million of expense to Cost of sales.

In February 2018, the FASB issued ASU 2018-02 “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The ASU affects any entity that is required to apply the provisions of Topic 220, Income Statement—Reporting Comprehensive Income, and has items of other comprehensive income for which the related tax effects are presented in other comprehensive income as required by GAAP. The ASU is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard requires a retrospective application to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” a new comprehensive revenue recognition standard that supersedes previous guidance under U.S. GAAP.
