(1)			Diluted earnings per common share for the three and six months ended September 30, 2011 and 2010 excludes approximately 1.5 million potentially dilutive shares initially issuable upon the conversion of our 3% Convertible Senior Notes. The 3% Convertible Senior Notes will be convertible, under certain circumstances, using a net share settlement process, into a combination of cash and our Common Stock. The initial base conversion price of the notes is approximately $77.34, based on the initial base conversion rate of 12.9307 shares of Common Stock per $1,000 principal amount of convertible notes (subject to adjustment in certain circumstances, including the payment of dividends). The payment of the $0.15 per share dividend payable on December 12, 2011 to holders of record as of November 18, 2011 may result in an adjustment to the initial base conversion rate. In general, upon conversion of a note, the holder will receive cash equal to the principal amount of the note and Common Stock to the extent of the note’s conversion value in excess of such principal amount. In addition, if at the time of conversion the applicable price of our Common Stock exceeds the base conversion price, holders will receive up to an additional 8.4049 shares of our Common Stock per $1,000 principal amount of notes, as determined pursuant to a specified formula. Such shares did not impact our calculation of diluted earnings per share for three and six months ended September 30, 2011 and 2010 as our stock price did not meet or exceed $77.34 per share.
