Notes to Results of Operations and Results of Operations – As Adjusted

(1) Other income, net included royalty income for the 2007 third quarter and first nine months of $63,265 and $202,048, respectively, compared with $60,630 and $193,864 for the prior year.

(2) The average number of common shares outstanding for diluted earnings per share is higher than for basic earnings per share due to the assumed conversion of the Company’s outstanding convertible senior debentures, outstanding stock options, deferred contingent common stock awards, restricted stock awards and convertible preferred stock into common stock equivalents using the treasury stock method. For purposes of calculating diluted earnings per share, interest expense, net of capitalized interest and taxes related to the Company’s outstanding convertible senior debentures is added back to reported net income, and the additional common shares (assuming conversion) are included in total shares outstanding. Interest expense, net of capitalized interest and taxes was $7,838 and $23,617 for the 2007 third quarter and first nine months, respectively, compared with $8,100 and $21,841 for the 2006 third quarter and first nine months, respectively.

(3) Charges related to activities associated with the Company’s productivity initiatives and the 2006 income tax adjustment are considered certain significant items and have been excluded from the results of operations – as adjusted for the 2007 and 2006 third quarter and first nine months as follows:

     Productivity Initiatives

	(UNAUDITED)
	Three Months Ended				Nine Months Ended
(In thousands, except per share amounts)	9/30/2007		9/30/2006		9/30/2007		9/30/2006
Cost of Goods Sold	$	111,200	$	31,300	$	182,400	$	86,500
Selling, General and Administrative Expenses		5,900		43,700		26,900		54,800
Research and Development Expenses		—		5,200		200		13,500
Total Productivity Initiatives Charges	$	117,100	$	80,200	$	209,500	$	154,800
Productivity Initiatives Charges, After-tax	$	86,000	$	54,900	$	152,500	$	106,400
Decrease in Diluted Earnings per Share	$	0.06	$	0.04	$	0.11	$	0.08

     Income Tax Adjustment

Included in the 2006 third quarter and first nine months is an income tax adjustment of $70.4 million ($0.05 per share-diluted) related to the reduction of certain deferred tax asset valuation allowances.

Wyeth calculates net income before certain significant items by excluding the after-tax effect of items considered by management to be unusual from the net income reported under generally accepted accounting principles (GAAP). Wyeth’s management uses this measure to manage and evaluate the Company’s performance and believes it is appropriate to disclose this non-GAAP measure to assist investors with analyzing business performance and trends. The productivity initiatives charges, which include costs associated with the Global Business Operations initiative, the costs of closing certain manufacturing facilities, including accelerated depreciation, certain reorganization expenses and the elimination of certain positions at the Company’s facilities, and the income tax adjustment related to the reduction of certain deferred tax asset valuation allowances have been excluded as they are not considered to be indicative of continuing operating results. Wyeth’s management believes that excluding these items from the Company’s results provides a more appropriate view of the Company’s operations for the accounting periods presented. These measures should not be considered in isolation or as a substitute for the results of operations and diluted earnings per share prepared in accordance with GAAP.
