Depreciation and Amortization Expense

We recognized depreciation expense in income from continuing operations of $11.5 million and $9.5 million in the three months ended March 29, 2015 and March 30, 2014, respectively. The increase in depreciation expense is primarily due to our acquisitions of Tripwire and Grass Valley.

We recognized amortization expense in income from continuing operations related to our intangible assets of $26.5 million and $11.7 million in the three months ended March 29, 2015 and March 30, 2014, respectively. The increase in amortization expense is primarily due to our acquisitions of Tripwire, Grass Valley, ProSoft, and Coast.
