Impact of Recent Accounting Pronouncements [Abstract]
Impact of Recent Accounting Pronouncements	In May 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU clarifies when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. The guidance requires modification accounting if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption available. The Company adopted the standard on January 1, 2018. The adoption did not have an impact on its financial position, results of operations and cash flows. In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost. This ASU requires employers to report the service cost component in the same line item as other compensation costs arising from services rendered by employees during the reporting period. The other components of net benefit costs will be presented in the income statement separately from the service cost and outside of a subtotal of income from operations. In addition, only the service cost component may be eligible for capitalization where applicable. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption available. The Company adopted the standard on January 1, 2018. The adoption of this standard resulted in the reclassification on the statements of income of the components of net periodic pension cost other than service cost from operating expenses to other pension costs in other income (expenses) of $321 and $305 for the three months ended June 30, 2018 and 2017, respectively, and $642 and $610 for the six months ended June 30, 2018 and 2017, respectively. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 320): Classification of Certain Cash Receipts and Cash Payments. This ASU clarifies how certain cash receipts and payments should be presented in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption available. The Company adopted the standard on January 1, 2018. The adoption did not have an impact on its financial position, results of operations and cash flows. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance in Accounting Standard Codification 840 – Leases. This ASU requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. This ASU is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years. The Company is currently assessing the impact of the adoption of the standard, but it expects the adoption will not have a material effect on its financial position, results of operations and cash flows. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. This ASU supersedes the revenue recognition requirements in Accounting Standards Codification 605—Revenue Recognition and most industry-specific guidance throughout the Codification. The standard requires that an entity recognizes 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. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, deferring the effective date of this amendment for public companies by one year to fiscal years beginning after December 15, 2017. Early adoption was permitted for fiscal years beginning after December 15, 2016, the original effective date. The standard permits the use of either a retrospective or cumulative effect transition method. The Company adopted the standard on January 1, 2018. The Company determined that the revenue recognized under the new standard is materially the same as it recognized under previous guidance. In addition, the Company determined the timing of when the revenue is recognized is materially the same as it recognized under previous guidance. As a result, there is no impact on its results of operations or cash flows. The Company has complied with the new disclosure requirements included in this standard which does have a significant impact on its disclosures. The Company selected the modified retrospective transition method, but based on the determination that there was no change to its revenue recognition, no cumulative effect of the changes was required to be recorded.
