Shareholders' Equity and Share Based Payment
Note 7. Shareholders’ Equity and Share Based Payment
     In March 2011, the Company’s Board of Directors authorized the repurchase of up to $60,000 of the Company’s common shares. In June 2011, the Company’s Board of Directors authorized an increase in the Company’s share repurchase program by up to an additional $30,000 of its common shares, for a total of up to $90,000 of its common shares in the aggregate. Under the program, the Company may purchase its common shares from time to time in the open market or in privately negotiated transactions. The amount and timing of the purchases will depend on a number of factors, including the price and availability of the Company’s common shares, trading volume and general market conditions. The Company may also from time to time establish a trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934 (the “Exchange Act”) to facilitate purchases of its common shares under this authorization. Through September 30, 2011, we repurchased 7,552,820 shares at a total cost of $90,000 including commissions, completing the share purchases to the authorized amounts.
