New Accounting Pronouncements
 
In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2017-07 “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post Retirement Benefit Cost” (“ASU 2017-07”). This new standard requires that employers disaggregate the service cost component from the other components of net periodic benefit cost in the income statement. The service cost component should be included in the same line item as other compensation costs rendered by employees, while the other cost components should be presented outside of earnings from operations. The amendments in this update are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted. The Company retrospectively adopted this ASU in the first quarter of 2017. Accordingly, the service cost component of net periodic benefit cost was included within selling and administrative expenses while the other cost components were classified in other expense, net, in the Consolidated Condensed Statements of Earnings and Comprehensive Income (Unaudited). See Note 8.
