[1] Exercise prices exceed the average market price of the common shares or are anti-dilutive due to the impact of the unrecognized compensation cost on the calculation of assumed proceeds in the application of the treasury stock method.

[2] In June 2007, we issued $575 million of senior convertible notes due July 2013. The impact of a net share settlement of the conversion amount at maturity will begin to dilute earnings per share if and when our stock price reaches $52.18. The impact of stock that could be issued to settle share obligations we could have under the warrants we issued simultaneously with the senior convertible notes issuance will begin to dilute earnings per share when our stock price reaches $66.79. The potential receipt of MCBC stock from counterparties under our purchased call options when and if our stock price is between $52.18 and $66.79 would be anti-dilutive and excluded from any calculations of earnings per share.

[3] Upon closing of the Acquisition in June 2012, we issued a €500 million Zero Coupon Senior Unsecured Convertible Note due 2013 to the Seller. The impact of a net share settlement of the conversion amount at maturity will begin to dilute earnings per share if and when our stock price reaches $51.25 based on foreign exchange rates at December 29, 2012.
