Acquisitions	8. Acquisitions Certain acquisition-related restricted stock agreements entered into prior to January 1, 2009 contained stock price guarantees that would result in cash payments if our per share price fell below a specified per share market value on the date that the applicable stock restrictions lapsed (the “determination date”). For those acquisitions, the settlement of the stock price guarantees related to our common stock price was recorded as a reduction to additional paid-in capital as of the determination dates. During the three and six months ended June 30, 2013, we paid $3.1 million and $3.9 million, respectively, in cash in relation to the stock price guarantees on certain shares of common stock that became unrestricted, which was recorded as a reduction to additional paid-in-capital on the Condensed Consolidated Balance Sheets. As of June 30, 2013, no further acquisition-related stock price guarantees are outstanding. 2013 Acquisitions During the second quarter of 2013, we completed two business combinations. The total purchase price included initial consideration with a value of $26.8 million plus acquisition-related contingent consideration. The contingent consideration is payable through the next five years if the acquired businesses meet certain performance measures. During the first quarter of 2013, we completed two business combinations. The total purchase price included initial consideration with a value of $9.1 million plus, for one of the business combinations, acquisition-related contingent consideration. The contingent consideration is payable annually through December 31, 2017 if the acquired business meets certain performance measures, and is subject to an $8.0 million aggregate cap. For acquisitions completed during the six months ended June 30, 2013, as part of the preliminary purchase price allocations, we recorded $9.4 million in identifiable intangible assets and $27.2 million in goodwill. The estimated fair value of the acquisition-related contingent consideration of $8.2 million is recorded in “Other liabilities” on the Consolidated Balance Sheets. Pro forma results of operations were not presented because these acquisitions were not material in relation to our consolidated financial position or results of operations for the periods presented.
