The Share Repurchase Program has no time limit and may be suspended or discontinued completely at any time. The number of shares to be purchased and the timing of purchases will be based on the Company’s trading windows and available liquidity, general business and market conditions, and other factors, including legal requirements, debt covenant restrictions and alternative investment opportunities.
