Accounting Standard EITF 04-8
During 2005, General Mills adopted EITF 04-8, which requires contingently convertible debt to be treated as if it had already been converted to common shares when calculating EPS. For General Mills, this results in the addition of 29 million shares to the total diluted shares outstanding until the contingently convertible debentures issued in October 2002 are redeemed. General Mills has restated diluted shares outstanding and diluted EPS beginning with the second quarter of fiscal 2003.
