&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&lt;b&gt;(4) Acquisitions&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We account for acquisitions using the acquisition method of accounting, and, accordingly, the results of operations for each acquisition have been included in our consolidated results from their respective acquisition dates. Cash consideration for our various acquisitions was primarily provided through borrowings under our credit facilities and cash equivalents on-hand. The unaudited pro forma results of operations for the period ended June&amp;#160;30, 2013 are not presented due to the insignificant impact of the 2012 and 2013 acquisitions on our consolidated results of operations.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June 2013, in order to further enhance our existing operations in Brazil, we acquired the stock of Archivum Comercial&amp;#160;Ltda. and AMG Comercial&amp;#160;Ltda., storage rental and records management businesses in Sao Paulo, Brazil, in a single transaction for an aggregate purchase price of approximately $29,000. Included in the purchase price is approximately $2,900 held in escrow to secure a working capital adjustment and the indemnification obligations of the former owners of the businesses to us.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In May 2013, we acquired a storage rental and records management business in Texas with locations in Michigan, Texas and Florida, in a cash transaction for a purchase price of approximately $25,000. Included in the purchase price is approximately $1,600 held in escrow to secure a working capital adjustment. The amounts held in escrow for purposes of the working capital adjustment will be distributed either to us or the former owners based on the final agreed upon working capital amount.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times;"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;A summary of the cumulative consideration paid and the preliminary allocation of the purchase price paid for acquisitions in 2013 through June&amp;#160;30, 2013 is as follows:&lt;/font&gt;&lt;/p&gt;
