Acquisitions</b> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">On November 9, 2009, we entered into a joint venture with Encompass Group, LLC (“Encompass Group”), to form Encompass TSS, LLC (“Encompass”), of which we ultimately owned 60 percent. For our 60 percent ownership interest we paid $7.5 million to Encompass Group, contributed cash and entered into license and distribution agreements with Encompass. On November 30, 2010, we purchased the remaining 40 percent of Encompass for $10.6 million, plus a variable earn-out with a minimum of $1.2 million and a maximum of $1.6 million per year over five years. We have a total of $5.6 million accrued in other current liabilities and other long-term liabilities on our Condensed Consolidated Balance Sheet at March 31, 2011 related to the earn-out. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">If the Encompass joint venture had been consummated at the beginning of our 2010 fiscal year or wholly-owned, the impact to revenues and net income on an unaudited pro forma basis would not have been significant to our financial results in any of the periods presented. </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescription of a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities.
