In the first quarter of 2006, we were notified by the Internal Revenue Service (IRS) Appeals Division that a resolution had been reached on the matter that we were in the process of appealing related to the tax deductibility of an acquisition-related breakup fee paid by the Warner-Lambert Company in 2000.

We report Adjusted income in order to portray the results of our major operations—the discovery, development, manufacture, marketing and sale of prescription medicines for humans and animals—prior to considering certain income statement elements. We have defined Adjusted income as Net income before the impact of purchase accounting for acquisitions, acquisition-related costs, discontinued operations and certain significant items. The Adjusted income measure is not, and should not be viewed as, a substitute for U.S. GAAP Net income.

The Adjusted income measure is an important internal measurement for Pfizer. We measure the performance of the overall Company on this basis, in conjunction with other performance metrics. The following are examples of how the Adjusted income measure is utilized.

• Senior management receives a monthly analysis of our operating results that is prepared on an Adjusted income basis;

• Our annual budgets are prepared on an Adjusted income basis; and

• Senior management’s annual compensation is derived, in part, using this Adjusted income measure. Adjusted income is one of the performance metrics utilized in the determination of bonuses under the Pfizer Inc Executive Annual Incentive Plan that is designed to limit the bonuses payable to the Executive Leadership Team
