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 standard was effective for interim and annual reporting periods beginning after December 15, 2017 and may be adopted either retrospectively or on a modified retrospective basis. 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 are 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. The Company adopted ASU 2014-09 on January 1, 2018. See the revenue recognition footnote for additional information. Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"), which 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. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The new standard must be adopted using a modified retrospective transition. The Company has established a cross-functional team to evaluate and implement the new standard. 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 and 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 Note 7 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 March 31, 2018, the Company has not completed the accounting for the tax effects of the enactment of the Act; 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 three months ended March 31, 2018. In all cases, the Company will continue to make and refine the calculations as additional analysis is 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 the effects and has not yet determined the new accounting policy. 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, Compensation-Retirement Benefits (Topic 715) ("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 statement of income and comprehensive income. This standard was effective for interim and annual reporting periods beginning after December 15, 2017 and early adoption is permitted. 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.
