Planning Horizon (Age) 3/14/2017 Retirement Income Philosophies Prioritization Among Goals Investment Approach Measuring Retirement Success Safe Withdrawal Rate Probability-Based Focus on overall lifestyle spending goals Focus on a total returns investing for the entire financial portfolio to maximize returns for an acceptable level of volatility Focus on determining an acceptable probability of failure for the overall retirement plan The historical record suggests that 4% or 4.5% is about as bad as it gets Safety-First Distinguish retirement spending goals between essential needs and discretionary expenses Match assets to different goals so that risk levels are compatible. Allows a wider role for holding individual bonds and using income annuities. Seeks to minimize harms in worst-case scenarios by avoiding failure for essential needs Unknown and unknowable.

#1 Is US historical data representative of future? Is U.S. Historical Data Sufficiently Representative? Time period since 1926 is too short (less than 3 independent 30 year periods) The 20 th century United States is a rather remarkable and unparalleled period in world history should this experience really be projected forward? Current market conditions matter much more for sustainable spending rates than historical averages We really have very little basis for knowing the suitability of our simulation input assumptions Maximum Sustainable Withdrawal Rates for Retirees Global Returns Dataset, 1900-2015 Asset Allocation: 50% Stocks & 50% Bills Importance of Current Market Conditions Sources of bond returns: Initial Bond Yield Subsequent Yield Changes Sources of stock returns: Dividend Income Growth of the Underlying Earnings Changes in the Valuation Multiples Placed on Those Earnings 7

Importance of Current Market Conditions 2 approaches to incorporate current market conditions: 1) Regression analysis to explain sustainable withdrawal rates with retirement date market conditions 2) Incorporate current conditions (instead of historical averages) into input assumptions for Monte Carlo simulation analysis Actual and Predicted Maximum Sustainable Withdrawal Rates For 50/50 Asset Allocation, 30-Year Retirement Period Estimated for Years 1881-1987, Explanatory Variables: PE10 and 10-Year Treasury Rate Portfolio Success Rates for a 4% Withdrawal Rate Rolling vs. Monte Carlo Simulations For a 30-Year Retirement, Inflations Adjustments #2 Integrating Pre- and Post-Retirement Periods 9
Safe Savings Rates Traditional wealth accumulation targets do not provide the most effective framework for retirement planning. Even if they did, financial market volatility makes it hard to judge whether one is on track to meet such targets. Rather, integrate the pre-retirement and post-retirement periods together to see what must be done prior to retirement in order to accumulate enough to afford one s desired retirement expenditures.

#3 Earning the Index Returns Portfolio Underperformance and Poor Investment Decisions Impact of a 1% Annual Account Underperformance Historical Simulations 1966 retirees are the source of our SAFEMAX With market index returns, 1966 retiree: 4.03% withdrawal rate. With 1% underperformance, 1966 retiree: Withdrawal rate falls by 0.48 percentage points to 3.56%. Reduced spending power by 11.9%. Across the historical period, fees caused the maximum sustainable withdrawal rates to fall on average by 0.65 percentage points or 11% of spending power. Buying High and Selling Low One example: high valuations result in a 0% stock allocation, medium valuations result in 50% stocks, and low valuations result in 75% stocks. This strategy lowers sustainable withdrawal rates compared to a fixed 50/50 allocation in almost all years. The SAFEMAX falls to 3.06%, compared to a 3.95% SAFEMAX with the fixed 50/50 allocation. (This analysis was with a different dataset) 22.5% spending reduction at the SAFEMAX; 29 years in which sustainable withdrawal rate falls below 4% Maximum Sustainable Withdrawal Rates, 50% Stock Allocation and Market Mistiming Asset Allocation, 30-Year Retirement 11
Role of Taxes Standard safe withdrawal rate assumption is a taxdeferred financial portfolio #4 Taxes Taxable portfolio: Taxes must also be paid on reinvested dividends, interest, and capital gains as they accrue. This limits the chance for the portfolio to earn compound growth on those removed tax payments. William Bengen estimated: 20% effective tax rate reduces his SAFEMAX from 4.15% to 3.67% #5 Bequests and a Margin of Safety SAFEMAX for Three Scenarios, 50/50 Portfolio The classic case, no wealth after 30 years: 4.03% Nominal value of retirement date wealth is preserved after 30 years: SAFEMAX = 3.77% Real inflation-adjusted value of retirement date wealth is preserved after 30 years: SAFEMAX = 2.72% 12
Portfolio Real Return Portfolio Real Return 3/14/2017 The 4% rule assumes only a few asset classes. #6 Broader Portfolio Diversification William Bengen s initial research: large-cap stocks and intermediate-term government bonds What matters for sustainable withdrawal rates are the interaction of portfolio returns and volatilities. Including more asset classes can allow for different portfolio characteristics and potentially a portfolio with better return/volatility characteristics can be found.

Constant Inflation-Adjusted Spending Amounts Advantages: -Smooth consumption path Disadvantages: -Wealth can be depleted 15
Constant Percentage of Remaining Assets Variable Spending Strategies in Retirement Advantages: -Since spending adjusts, cannot deplete wealth -Spending can increase on upside -Helps mitigate sequence of returns risk -More efficient in the sense of using a greater percentage of assets Disadvantages: -Variable and unpredictable spending path Decision Rule Methods Bengen's Constant Inflation-Adjusted Spending (1994) Bengen's Fixed-Percentage Withdrawals (2001) Bengen's Floor-and-Ceiling Withdrawals (2001) Guyton and Klinger's Decision Rules (2006) David Zolt's Target Percentage Adjustment (2013) Actuarial Methods RMD Spending Rules PMT Formula (ex.
