Additional Contingent Purchase Consideration As part of the agreement to acquire a subsidiary by the ETG in fiscal 2007, the Company may have been obligated to pay additional purchase consideration of up to 73 million Canadian dollars in aggregate, which translates to approximately $74 million U.S. dollars based on the April 30, 2012 exchange rate, should the subsidiary meet certain earnings objectives through June 2012. Based on the current level of earnings during the measurement period, the Company does not expect to pay any additional purchase consideration. Litigation The Company is involved in various legal actions arising in the normal course of business. Based upon the Company’s and its legal counsel’s evaluations of any claims or assessments, management is of the opinion that the outcome of these matters will not have a material adverse effect on the Company’s results of operations, financial position or cash flows.
