Reclassifications
 
Certain prior year amounts in the Consolidated Condensed Statements of Earnings and Comprehensive Income (Unaudited) were reclassified to conform to current year presentation. For the three and nine months ended September 30, 2016, the Company reclassified $424,000 and $1,272,000, respectively, of expense from selling and administrative expenses to other expense, net. These amounts represent the non-service cost components of net periodic pension cost for the periods then ended, and were reclassified in connection with the adoption of ASU 2017-07. These reclassifications had no effect on previously reported net earnings or equity.
