(1) Operating earnings exclude net realized capital gains and losses from net income. Net realized capital gains and losses arise from various types of transactions, primarily in the course of managing a portfolio of assets that support the payment of liabilities. However, these transactions do not directly relate to the underwriting or servicing of products for customers and are not directly related to the core performance of Aetna’s business operations. Management believes that operating earnings and operating earnings per share provide a more useful comparison of Aetna’s underlying business performance from period to period. Management uses operating earnings to assess business performance and to make decisions regarding Aetna’s operations and allocation of resources among Aetna’s businesses. Operating earnings is also the measure reported to the Chief Executive Officer for these purposes.
For a reconciliation of this item to financial measures calculated under U.S. generally accepted accounting principles (GAAP), refer to the tables on pages 7 through 8 and page 10 of this press release.
(2) Projected operating earnings per share exclude any future net realized capital gains or losses and other items, if any, from net income. Aetna is not able to project the amount of future net realized capital gains or losses and therefore cannot reconcile projected operating earnings to projected net income, or to a projected change in net income, in any period. Projected operating earnings per share for the full-year 2008 assumes less than 505 million weighted-average diluted shares.
(3) Operating expenses as a percentage of revenue excludes net realized capital gains and losses from total revenue.
(4) In order to provide useful information regarding Aetna’s profitability on a basis comparable to others in the industry, without regard to financing decisions, income taxes or amortization of other acquired intangible assets (each of which may vary for reasons not directly related to the performance of the underlying business), Aetna’s pretax operating margin is based on operating earnings excluding interest expense, income taxes and amortization of other acquired intangible assets. Management also uses pretax operating margin to assess Aetna’s performance, including performance versus competitors.
(5) Revenue and operating expense information is presented before income taxes. Operating earnings information is presented net of income taxes.
(6) Segment revenue includes net realized capital gains and losses.
(7) At March 31, 2008, approximately 28,000 and 22,000 State Children’s Health Insurance Program (“SCHIP”) medical members and 21,000 and 19,000 of both SCHIP pharmacy and dental members at December 31, 2007 and March 31, 2007, respectively, were reclassified from Commercial to Medicaid.

ADDITIONAL INFORMATION; CAUTIONARY STATEMENT -- Certain information in this press release is forward looking, including our projections as to operating earnings, medical membership growth and weighted-average diluted shares. Forward-looking information is based on management's estimates, assumptions and projections, and is subject to significant uncertainties and other factors, many of which are beyond Aetna's control. Important risk factors could cause actual future results and other future events to differ materially from those currently estimated by management, including failure to achieve desired rate increases and/or profitable membership growth due to significant competition, reputational issues or other factors in key geographic markets where membership is concentrated; unanticipated increases in medical costs (including increased medical utilization, increased pharmacy costs, increases resulting from unfavorable changes in contracting or re-contracting with providers, changes in membership mix to lower-premium or higher-cost products or membership-adverse selection; as well as changes in medical cost estimates due to the necessary extensive judgment that is used in the medical cost estimation process, the considerable variability inherent in such estimates, and the sensitivity of such estimates to changes in medical claims payment patterns and changes in medical cost trends); and the ability to reduce administrative expenses while maintaining targeted levels of service and operating performance. Other important risk factors include, but are not limited to: the ability to improve relations with providers while taking actions to reduce medical costs; the ability to successfully integrate our businesses (including acquired businesses) and implement multiple strategic and operational initiatives simultaneously; reduced levels of investment income from low interest rates; adverse government regulation (including legislative proposals eliminating or reducing ERISA pre-emption of state laws that would increase potential litigation exposure, legislative proposals that would limit our ability to price for the risk we assume and/or reflect reasonable costs or profits in our pricing, and other proposals, such as patients' rights legislation, that would increase potential litigation exposure or mandate coverage of certain health benefits); adverse pricing or funding actions by government payors; changes in size, product mix or medical cost experience of membership in key markets; our ability to integrate, simplify, and enhance our existing information technology systems and platforms to keep pace with changing customer and regulatory needs; the outcome of various litigation and regulatory matters, including litigation and ongoing reviews of business practices by various regulatory authorities (including the current industry-wide investigation by the New York Attorney General into certain payment practices with respect to out-of-network providers); and increases in medical costs or Group Insurance claims resulting from any acts of terrorism, epidemics or other extreme
