CDI Corp. acquired EdgeRock on October 6, 2015 and management excluded EdgeRock from its assessment of the effectiveness of its internal control over financial reporting. EdgeRock represented approximately 1% and 11% of the Company's total revenue and total assets as of and for the year ended December 31, 2015. Our audit of internal control over financial reporting of CDI Corp. also excluded an evaluation of the internal control over financial reporting of EdgeRock.
