Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Revenue from Contracts with Customers (Topic 606) In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, which creates a single, comprehensive revenue recognition model for recognizing revenue from contracts with customers. The Company adopted ASU 2014-09 and its amendments on January 1, 2018. 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. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than were required under previously existing guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others. ASU 2014-09 did not result in a significant change in the judgment or timing associated with the recognition of revenue from the sale of the Company’s products or services. See the revenue recognition footnote for additional information. Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"), which, among other things, requires an entity to recognize a right-of-use asset and a lease liability on the balance sheet for all leases, including operating leases, with a term greater than twelve months. Expanded disclosures with additional qualitative and quantitative information will also be required. ASU 2016-02 and its amendments are effective for interim and annual reporting periods beginning after December 15, 2018 and early adoption is permitted. In July 2018, the FASB issued amendments in ASU 2018-11, which provide a transition election to not restate comparative periods for the effects of applying the new standard. This transition election permits entities to change the date of initial application to the beginning of the year of adoption and to recognize the effects of applying the new standard as a cumulative-effect adjustment to the opening balance of retained earnings. The Company expects to elect this transition approach and recognize the cumulative impact of adoption in the opening balance of retained earnings as of January 1, 2019. The Company has established a cross-functional team and it is continuing to evaluate the new standard and prepare for implementation. As disclosed in the leased properties footnote in the 2017 Annual Report on Form 10-K, the future minimum payments under noncancelable operating leases are approximately $1,140,000 as of December 31, 2017. The Company believes the adoption of this standard will have a significant impact on the consolidated balance sheets. Income Tax Reform As more fully discussed in the income taxes footnote of the Company’s notes to the consolidated financial statements in its 2017 Annual Report on Form 10-K, the Tax Cuts and Jobs Act ("the Act") was enacted December 22, 2017. As of September 30, 2018, the Company has not completed the accounting for the tax effects of the enactment of the Act due to its complexities and the limited guidance available; however, the Company has made a reasonable estimate of the effect of the Act on the existing deferred tax balances and of the one-time transition tax. There was no impact on the tax rate as a result of a change in estimate for the nine months ended September 30, 2018. In all cases, the Company continues to refine the calculations as additional analysis and modeling are completed. Further, the Company's estimates may also be affected as regulations and additional guidance become available. In addition, the Act subjects a U.S. shareholder to tax on Global Intangible Low-Taxed Income ("GILTI") earned by certain foreign subsidiaries. Given the complexity of the GILTI provisions, the Company is still evaluating its effects and has not yet made an accounting policy election. The provision is not expected to have a material impact on the Company’s consolidated financial statements or related disclosures. Compensation-Retirement Benefits (Topic 715) In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"), which requires an entity to report the service cost component of net periodic benefit cost in the same line item as other compensation costs (selling, administrative and other expenses) and the remaining components in non-operating expense in the consolidated statements of income and comprehensive income. The Company adopted ASU 2017-07 retrospectively on January 1, 2018 and it did not have a material impact on the Company's condensed consolidated financial statements or related disclosures. See the employee benefit plans footnote for additional information. The Company elected to use the amounts disclosed in the employee benefit plans footnote for the prior comparative period as the basis for applying the retrospective presentation. Derivatives and Hedging (Topic 815) In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"), which eliminates the requirement to separately measure and report hedge ineffectiveness and requires companies to recognize all elements of hedge accounting that impact earnings in the same line item in the statement of income where the hedged item resides. The amendments also ease the requirements for effectiveness testing, hedge documentation and applying the critical terms match method, among other things. ASU 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The standard must be applied using a modified retrospective transition approach. The Company early adopted ASU 2017-12 as of July 1, 2018 and it did not have a material impact on the Company’s consolidated financial statements or related disclosures.
