Under the share buyback program, the Company is authorized to repurchase from time to time shares of its outstanding common stock on the open market or in privately negotiated transactions in the United States. The timing and amount of stock repurchases will depend on a variety of factors, including the market conditions as well as corporate and regulatory considerations. The share repurchase program may be suspended, modified or discontinued at any time and the Company has no obligation to repurchase any amount of its common stock under the program. The repurchase program has no set expiration date. The company intends to make all repurchases in compliance with applicable regulatory guidelines and to administer the plan in accordance with applicable laws, including Rule 10b-18 of the Securities Exchange Act of 1934, as amended. The company had a total combined number of common stock and exchangeable shares issued and outstanding of 43,091,494 shares at March 31, 2010.
