S . Aggregate Bond Total Return Index . The “Global 30 / 70 Portfolio (ER)” is a notional portfolio providing a monthly - rebalancing 30 % / 70 % weighted exposure to the MSCI ACWI Net Total Return Index and the Bloomberg Barclays Global Aggregate Total Return Index Value Unhedged USD (a global investment - grade bond index) .

Morgan Cash Index USD 3 Month, which tracks the return of a notional 3 - month U . S . dollar time deposit .

The notional portfolios track assets that ditfer from those tracked by the Index and are not rebalanced on the same schedule as the Index . All performance data for the Domestic 30 / 70 Portfolio (ER) and the Global 30 / 70 Portfolio (ER) is hypothetical and there is no guarantee that the Index will outperform either one, or any other benchmark or index, in the future . PAST PERFORMANCE AND BACKTESTED PERFORMANCE ARE NOT INDICATIVE OF FUTURE RESULTS . Please see the Disclaimer on the following page . PERFORMANCE UPDATE The S&P 500 ® Daily Risk Control 5 % Index (the “Index”) represents a portfolio consisting of the S&P 500 and a cash component accruing interest that dynamically adjusts to target a 5 % level of volatility . Volatility is calculated as a function of historical returns that uses exponential weightings to give more significance to recent observations . S&P Risk Control Indices use an overlay designed to maintain risk at a predefined level — in this case, up to 5 % volatility . The risk control framework is applied to the underlying index and helps to reduce portfolio volatility to the 5 % target by moving a portion of the portfolio allocation from the underlying index to cash in volatile markets and from cash to the underlying index in less volatile markets . The Index is calculated on an excess return basis. The Index was established on September 10, 2009. Levels are published on Bloomberg using the ticker SPXT5UE.
