1. University of California Summary of University of California Retirement Plan Asset/Liability Forecast Study — January 2002 Regents Meeting May15 &16, 2002

2. Asset/Liability Studies — Purpose • Study Objectives/Purpose: 1. Demonstrate fiduciary due diligence 2. Assess current funding policy 3. Address concerns over interest rates and inflation 4. Determine adequacy of assets in conjunction with liabilities 5. Review impact of future plan changes, demographics and cash flow

3. Asset/Liability Studies — Background • The asset/liability study process requires the following steps: 1. Develop background information 2. Conduct planning meetings with the University 3. Develop baseline forecast results for twenty-year period 4. Generate stochastic results on the basis of a continuation of all current plan provisions and funding policies 5. Run multiple versions of financial analyses to test the effectiveness of the current policies and to identify efficient alternatives 6. Model possible future plan changes and alternative asset portfolios 7. Summarize and present results

4. Asset/Liability Studies — Background (continued) • Asset/liability modeling software forecasts financial results on both deterministic and stochastic bases, using a variety of user-specific assumptions and possible changes in plan provisions • The model consists of four integrated components: 1. The Liability Projections module calculates a stream of liabilities on the basis of the funding valuation assumptions • Developed for positive and negative changes in the key economic assumptions • Measures sensitivities that generate plan liabilities under all assumption sets needed for the stochastic forecast 2. The Capital Market module simulates interest rates, inflation and asset-class returns for several hundred economic scenarios • Tracks plausible paths as the capital markets move from today’s environment toward expected future results • Utilizes the cascade structure, starting with interest rates and moving through price and wage inflation to dividend growth and asset-class returns • Measures consistency between the movements of assets and liabilities

5. Asset/Liability Studies — Background (continued) 3. The Asset Portfolio module looks at a variety of asset mixes • Models efficient portfolios under a wide variety of risk and reward definitions • Measured with or without recognition of liability growth 4. The Financial Linkage module combines the results of the liability forecasts with alternative asset portfolios and develops • Integrated financial results • Several hundred capital-market scenarios; asset and liability values are determined at each point in time • Exact contribution calculations based on the declared funding policy These four modules have been applied in the modeling of assets and liabilities for the University of California Retirement Plan (UCRP).

6. Capital Market Simulation — A Cascade Model Short & Long Interest Rates & Full Treasury Curve Price Inflation Wage Inflation Domestic Stock Dividend Growth Domestic Stock Dividend Yield Domestic Stock Income & Total Return Cash & Long Bond Income & Total Return Other Asset Classes Capital Market Simulation Model — Assets • The simulated behavior of capital market variables -- volatility's and correlation's -- is based on historical behavior together with a judgement about how the future might differ from the past • Yield curves drive asset class performance and inflation

7. Short & Long Interest Rates & Full Treasury Curve Price Inflation Wage Inflation Plan Sponsor/ Actuary/ Regulatory Specifications COLA Demographic Factors Actuarial Valuation Assumptions Payroll Plan Provisions Liabilities Capital Market Simulation Model — Liabilities • Simulated yield curves and inflation affect both sides of the balance sheet • Yield curves drive liability measurement assumptions • Changes in assets and liabilities are coordinated

8. Long-Term Cost Impact of Plan Changes • Change in Actuarial Accrued Liability • The Actuarial Accrued Liability measures the “earned” portion of projected benefits. This is the liability measure shown in the annual actuarial valuation report • Actuarial Accrued Liability is based on current actuarial assumptions, current active and inactive plan members, and forecasts growth in membership • Proposed plan changes are described in several Regent’s items; the cost impact for these changes is summarized on page 19

9. Current Plan — Asset/Liability Modeling • Current Plan forecast results were developed using: • Current UCRP provisions • Active membership growth (assumed to be 2½% per year through 2011 and 1½% thereafter) • Asset allocation Current Policy A • US Bonds 35% 30% • TIPS 0%* 5% • US Equity 53% 53% • International Stocks 7% 7% • Private Equity 5% 5% • TOTAL 100% 100% *TIPS are included in U.S. Bonds under the current asset allocation (TIPS are currently 3.5% of total portfolio) • Portfolio statistics (Mean Return) • Nominal returns 8.29 8.28 • Real return 5.99 5.98 • Annual Std deviation 12.98 12.68

10. Current Plan Asset/Liability Modeling (continued) • Economic scenario • Return assumptions were a consensus of Wilshire Associates, UC Treasurers’ Office and Towers Perrin • The Towers Perrin simulation model was used to create scenarios of inflation, yields and asset class returns • The average US equity return premium is set at 3.0% above the average LPF Bond Index return. The equity return premiums for international stocks are set equal to the return premium for US equity, in order to maintain neutrality among the classes

11. Current Plan — Results • Contributions • Current contribution policy • Normal Cost plus thirty-year amortization of unfunded Actuarial Accrued Liability; if plan is Fully Funded the contribution is $0 • 2001/2002 Normal Cost (annual increase in liability due to additional service) • $975 million, or 14.9% of covered payroll • Funded ratios: • Funded ratios are calculated by dividing the Actuarial Value of Assets by the Actuarial Accrued Liability • Actuarial Value of Assets (AVA): A smoothed value of assets over a five-year period that minimizes the volatility of the financial markets • Actuarial Accrued Liability (AAL): The accrued liability as of any valuation for all benefits earned to date for active members, all benefits in pay status for retirees, beneficiaries and disabled members, and all deferred benefits for vested members who have terminated employment and will receive benefits in the future

12. Current Plan — Results • As of January 1, 2002 the funded ratio is 149% based on: • Previous years of significant investment gains created a cushion of assets due to the smoothing method. Over the forecast period the cushion is reduced and the Actuarial Value of Assets moves toward Market Value AVA = $41,570,000,000 AAL = $27,900,000,000 = 149%

13. Current Plan — Results • Probability of zero contributions • This is an indication of the need to make contributions during the twenty-year study • The probability shown on the graph is the cumulative probability; that is, if the probability is 75% in a specific year, that means there is a 75% probability there will be no contributions in that year OR any previous year • Results for the Current Plan • Funded ratios (pages 15 and 17) • Probability of zero contributions (page 18)

14. The following graphs show the results of the stochastic forecasts The medians or averages show the trend The range of results shows the volatility Each forecast includes 500 scenarios and the results are shown in percentiles The bar graphs show ranges of likely results by using floating bar graphs similar to the one shown below. These graphs are interpreted as follows: 95th percentile: 5% of the results are above this level Arithmetic average of all results for that period X.XX 75th percentile: 25% of the results are above this value Median : 50% of the results are above this level and 50% are below 25th percentile: 75% of the results are above this level 5th percentile: 95% of the results are above this level Bar Charts Explained

Relative Equity decreases the probability slightly Note: Only Policy A is shown, as it is very close to the Current Policy

25. Summary • The funded status has reduced since the prior study; smoothed asset values have dampened the effect of volatile market values • Probability of contributions has increased since 2000 due to recent asset performance and lower expected future returns • Effect of the Relative Equity changes have minimal impact on future liabilities and contributions to the plan
