^BBond and other fixed-income securities involve both credit risk and market risk, which includes interest rate risk. Credit risk is the risk that the security’s issuer will not pay the interest, dividends or principal that it has promised to pay.  Market risk is the risk that the value of the security will fall because of changes in market rates of interest or other factors.  Interest rate risk reflects the fact that the values of fixed-income securities tend to fall as interest rates rise. When interest rates go down, interest earned on fixed-income securities will tend to decline.

^DThe Portfolio may use derivative instruments for hedging purposes or as part of its investment strategy. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, market risk, credit risk, management risk and the risk that a fund could not close out a position when it would be most advantageous to do so.  Portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

^FForeign securities pose additional risks that are not associated with U.S. domestic issues, such as changes in currency exchange rates and different governmental regulations, economic conditions and accounting standards.

^GInvests in growth stocks, the prices of which may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

^RInvesting in real estate involves special risks, which may not be associated with investing in stocks, including possible declines in real estate values, adverse economic conditions, and changes in interest rates.

^SInvestments in small capitalization and emerging growth companies involve greater than average risk. Such securities may have limited marketability and the issuers may have limited product lines, markets and financial resources. The value of such investments may fluctuate more widely than investments in larger, more established companies.

^VInvests in stocks that tend to trade at lower prices relative to their fundamental financial characteristics and are therefore considered undervalued. Value stocks can perform differently than other categories of stocks (e.g., growth stocks) and can continue to be undervalued by the market for long periods of time.
