Acquisitions

During the nine months ended September 30, 2012, the Company revised the purchase price allocation for the acquisition of Continuous Computing as a result of final measurement period adjustments. This revision is the result of finalizing the accounting for certain tax matters, which was completed during the three months ended March 31, 2012. These adjustments resulted in an additional release of the Company's valuation allowance provided against its U.S. net deferred tax assets, which resulted in additional deferred tax benefit reported in third-quarter 2011 financial information of approximately $2.7 million. As required by ASC 805-10, the Company's statements of operations and cash flows for the period ending September 30, 2011, as well as the balance sheet at December 31, 2011, have been revised to reflect the impact of these measurement period adjustments.

The following tables summarize the purchase price allocation and the impact of these measurement period adjustments to the Company's previously filed statements of operations and cash flows for the period ending September 30, 2011, as well as the balance sheet at December 31, 2011:
