(1) The following table presents the computations for diluted earnings per share (EPS) computed under the treasury stock and the “if-converted” methods:

	Three Months Ended December 31,
	2005			2004
Income (Numerator):
Net income for basic EPS	$	824		$	689
Adjustment for interest expense on convertible notes, net of tax		—	(A)		6
Net income for diluted EPS, after assumed conversion of convertible notes	$	824		$	695
Shares (Denominator):
Weighted-average shares for basic EPS		1,229			1,263
Effect of dilutive securities		14			12
Effect of convertible notes, after assumed conversion		—	(A)		35
Weighted-average shares for diluted EPS		1,243			1,310
Diluted earnings per share	$	0.66		$	0.53

(A) On May 6, 2005 and August 17, 2005, in connection with an exchange offer, the Company modified the terms of approximately 99 percent of our convertible notes then outstanding (the “Modified Convertible Notes”). As a result of certain of these modifications, if converted, the Modified Convertible Notes would be settled in 1) cash equal to the lesser of the accreted value of the Modified Convertible Notes at the conversion date or the conversion value, as defined, and 2) shares of common stock, if any, to the extent the conversion value exceeds the accreted value. Accordingly, the Modified Convertible Notes do not impact diluted earnings per share under the “if-converted” method but rather, they impact diluted earnings per share under the treasury stock method, and only to the extent that the conversion value exceeds the accreted value during any reporting period, requiring such difference, if any, to be potentially settled in shares of common stock.

(1) On March 2, 2005, as a result of certain holders of the Convertible notes exercising their March 1, 2005 put option, the Company repurchased $1,175 million, or approximately 40 percent, of the outstanding Convertible notes at their then-accreted value for cash. Accordingly, the Convertible notes repurchased were classified as current liabilities at December 31, 2004.

(2) Holders of the remaining outstanding Convertible notes may require the Company to purchase all or a portion of the notes on specific dates as early as March 1, 2006 at the original issuance price plus accrued original issue discount through the purchase date. Accordingly, as of December 31, 2005, the Convertible notes have been classified as current liabilities.
