Greer At PIMCO Mr. Greer is an Executive Vice President and Manager of Real Return Products which embraces commodities, inflation-linked bonds, real estate and active asset allocation. Mr. Greer spent eight years managing commodity index business first for Daiwa Securities and then for both Chase Manhattan Bank and JP Morgan. Prior to this, he spent ten years in the investment real estate business. He is regarded as the first person to define an investable commodity index and is a pioneer in explaining why commodity indexes are an asset class distinct from stocks and bonds. He developed one of the two common methods of explaining sources of commodity index returns and has spoken on this asset class at universities, industry conferences, and trade meetings globally. He has also published articles on the subject in The Journal of Portfolio Management, The Journal of Derivatives, The Journal of Alternative Investments and Pensions & Investments. He has consulted on the subject of commodities to governmental entities such as the CIA, CFTC, and Bank of England. Mr. Greer wrote The Handbook of Inflation Hedging Investments, oriented to the institutional investment community, which was published by McGraw Hill in December 2005. Mr. Greer received a bachelors degree in mathematics and economics from Southern Methodist University. He earned an MBA from the Stanford Graduate School of Business.

Real coupons were based on average nominal yield less trailing three-year inflation, from 1900 - 2006, which averaged 1.25%. Monthly inflation accruals were based on monthly changes in the CPI index.

26. For Educational Use Only !edu_Why_Commodities For Educational Use Only Yale_Univ(10-15-08) Appendix Past performance is not a guarantee or a reliable indicator of future results. Chart Performance results for certain charts and graphs may be limited by date ranges specified on those charts and graphs; different time periods may produce different results. Correlation The statements contained in this presentation regarding the correlation of various indices or securities against one another or against inflation are based upon data over a long time period. These correlations may vary substantially in the future or over shorter time periods, resulting in greater volatility. Double Alpha The Double Alpha refers to a strategy that should provide excess return under the active management of collateral backing the commodity index. In addition, this strategy derives alpha from the structural commodity relative to the index. Hypothetical Example Hypothetical and simulated examples have many inherent limitations and are generally prepared with the benefit of hindsight. There are frequently sharp differences between simulated results and the actual results. There are numerous factors related to the markets in general or the implementation of any specific investment strategy, which cannot be fully accounted for in the preparation of simulated results and all of which can adversely affect actual results. No guarantee is being made that the stated results will be achieved. Risk Investing in the bond market is subject to certain risks including market, interest-rate, issuer, credit, and inflation risk. Commodities contain heightened risk including market, political, regulatory, and natural conditions, and may not be suitable for all investors. Derivatives and commodity-linked derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when most advantageous. Investing in derivatives could lose more than the amount invested.

27. For Educational Use Only !edu_Why_Commodities For Educational Use Only Yale_Univ(10-15-08) Appendix Efficient Frontier Models The Efficient frontier models represented in this report are bound by the data sets and date ranges used in those models. This model illustrates performance from 1976 to 2006. Different time periods or data sets may produce different results. Past performance is no guarantee of future results. Certain assumptions were made in this analysis, which have resulted in the returns detailed herein, changes to the assumptions may have an impact on any returns detailed. Transaction costs (such as commissions or other fees) are not included in the calculation of returns reflected, and changes to the assumptions may have an impact on any returns detailed in this document. If these fees and charges were included the performance results would be lower.
