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 the performance metric 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 (ELT) for purposes of Internal Revenue Code Section 162(m). Subject to the Section 162(m) limitation, the bonuses are funded from a pool based on the performance measured by three financial metrics, including adjusted diluted earnings per share, which is derived from Adjusted income. This metric accounts for 40% of the bonus pool. The pool applies to the bonus plans for virtually all bonus-eligible, non-sales-force employees worldwide, including the ELT members and other members of senior management.

Despite the importance of this measure to management in goal setting and performance measurement, Adjusted income is a non-GAAP financial measure that has no standardized meaning prescribed by U.S. GAAP and, therefore, has limits in its usefulness to investors. Because of its non-standardized definition, Adjusted income (unlike U.S. GAAP net income) may not be comparable to the calculation of similar measures of other companies. Adjusted income is presented solely to permit investors to more fully understand how management assesses performance.

We also recognize that, as an internal measure of performance, the Adjusted income measure has limitations, and we do not restrict our performance-management process solely to this metric. A limitation of the Adjusted income measure is that it provides a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles, and does not provide a comparable view of our performance to other companies in the biopharmaceutical industry. We also use other specifically tailored tools designed to achieve the highest levels of performance. For example, our R&D organization has productivity targets, upon which its effectiveness is measured. In addition, total shareholder return, both on an absolute basis and relative to a group of pharmaceutical industry peers, plays a significant role in determining payouts under certain of Pfizer’s long-term incentive compensation plans.

Purchase Accounting Adjustments

Adjusted income is calculated prior to considering certain significant purchase accounting impacts resulting from business combinations and net asset acquisitions. These impacts, primarily associated with Pharmacia (acquired in 2003), Wyeth (acquired
