Stock Purchase Plan

The Company has a share repurchase program (“Stock Purchase Plan”) under which it is authorized to purchase up to $250.0 million of its outstanding Class A common shares. In October 2011, the Company’s Board of Directors authorized an incremental $80.0 million increase to the Stock Purchase Plan. The timing and amount of any shares repurchased under the Stock Purchase Plan will depend on a variety of factors, including price, corporate and regulatory requirements, capital availability and other market conditions. The Stock Purchase Plan may be suspended or discontinued at any time without prior notice. No shares have been or will be knowingly purchased from Company insiders or their affiliates.

Since inception of the Stock Purchase Plan through August 31, 2011, the Company has purchased 5,963,581 shares of its Class A common shares, for a total of approximately $241.8 million. Included in these totals are the purchases of 740,968 shares of its Class A common shares during the nine months ended August 31, 2011, at an average cost of approximately $28.33 per share (including commissions), for a total of approximately $21.0 million. These transactions occurred in open market purchases and pursuant to a trading plan under Rule 10b5-1. At October 6, 2011, the Company had approximately $84.8 million, which includes the incremental increase, remaining repurchase authority under its current Stock Purchase Plan.
