Treasury Stock [Text Block]	11. TREASURY STOCK On June 1, 2007, the Corporation entered into an agreement with a financial institution to repurchase $200.0 of its outstanding Common Stock under an Accelerated Share Repurchase Agreement (the “ASR”). The entire $200.0 repurchase was executed under a “collared” transaction whereby a price range for the shares was established. Under the ASR, the Corporation initially received 5.1 million shares on June 28, 2007 (the “Initial Execution Date”), representing the minimum number of shares to be received based on a calculation using the “cap” or high-end of the price range collar. On October 29, 2007 (the “Settlement Date”), the Corporation received an additional 0.7 million shares at no additional cost, bringing the total number of shares repurchased under the ASR to 5.8 million shares, which is reflected in the Treasury Stock component of Stockholders’ Equity.

On December 20, 2007, the Company announced that its Board of Directors had authorized a program to repurchase up to $20.0 of Common Stock, from time to time as conditions allow, on the open market or through negotiated private transactions.

On December 16, 2009, the Company announced that its Board of Directors had authorized a further program to repurchase up to $20.0 of Common Stock, from time to time as conditions allow, on the open market or in negotiated private transactions.

In addition, pursuant to a subsequent Board of Directors authorization, on November 3, 2010 the Company completed a modified Dutch auction tender offer. The Company accepted for purchase 5,199,699 Common shares at a price of $30.00 per share for a total cost of $156.0, excluding related fees and expenses. The Common shares purchased pursuant to the tender offer represented approximately 15.1% of the Common shares outstanding as of October 27, 2010. The Company funded the purchase of the shares in the tender offer using cash on hand and short term borrowings under its existing credit facility, which borrowings were repaid prior to November 30, 2010.

As of May 31, 2011, $44.5 remains available for future purchases under the current Board of Directors authorizations, which purchases may be made from time to time as conditions allow, on the open market or in negotiated private transactions. The repurchase program may be suspended at any time without prior notice.
