Cost of Products Sold, Engineering and Development and Selling, General and Administrative Expenses

Cost of products sold includes the costs to manufacture products such as direct materials and labor and manufacturing overhead as well as all engineering and developmental costs. The Company is engaged in a variety of engineering and design activities as well as basic research and development activities directed to the substantial improvement or new application of the Company’s existing technologies. These costs are expensed when incurred and included in cost of products sold. Research and development, design and related engineering amounted to $22.2 million and $17.2 million for the three months ended April 4, 2015 and March 29, 2014, respectively. Selling, general and administrative expenses include costs primarily related to our sales and marketing departments and administrative departments. Interest expense is shown net of interest income. Interest income was insignificant for the three months ended April 4, 2015 and March 29, 2014.

Derivatives

In November 2014, the Company terminated its interest rate swap. Ineffectiveness was not significant for the three month period ended March 29, 2014. The Company classified the cash flows from hedging transactions in the same category as the cash flows from the respective hedged items. No derivative instruments were outstanding at or for the three month period ended April 4, 2015.

Foreign Currency Translation

The Company accounts for its foreign currency translation in accordance with Accounting Standards Codification (“ASC”) Topic 830, Foreign Currency Translation. The aggregate transaction gain or loss included in operations was insignificant for the periods ending April 4, 2015 and March 29, 2014.

Loss Contingencies

Loss contingencies may from time to time arise from situations such as claims and other legal actions. Loss contingencies are recorded as liabilities when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable. Disclosure is required when there is a reasonable possibility that the ultimate loss will exceed the recorded provision. Contingent liabilities are often resolved over long time periods. In recording liabilities for probable losses, management is required to make estimates and judgments regarding the amount or range of the probable loss. Management continually assesses the adequacy of estimated loss contingencies and, if necessary, adjusts the amounts recorded as better information becomes known.

There have been no recent accounting pronouncements that have had an impact on the Company’s financial statements.
