Because the values of the Fund's investments will fluctuate with market conditions, so will the value of your investment in the Fund. You could lose money on your investment in the Fund, or the Fund could underperform other investments. As with most fixed income funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns usually decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund's average portfolio maturity and the lower the average quality of its portfolio, the greater the price fluctuation. The price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments or its credit rating. Below investment grade debt securities are speculative and involve a greater risk of default and price change due to changes in the issuer's creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline significantly in periods of general economic difficulty. The Fund may hold illiquid securities which may reduce the return of the Fund because it may be unable to sell such illiquid securities at an advantageous time or price. Illiquid securities may also be difficult to value. The Fund is actively managed, and may frequently buy and sell securities. Frequent trading increases a Fund’s portfolio turnover rate and may increase transaction costs, such as brokerage commissions and taxes, which in turn could detract from the Fund’s performance.
Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments and other overall economic conditions in the countries where the Fund invests. Emerging country markets involve greater risk and volatility than more developed markets. Some emerging markets countries may have fixed or managed currencies that are not free-floating against the U.S. dollar. Certain of these currencies may experience substantial fluctuations or steady devaluation relative to the U.S. dollar. Mortgage-related securities are subject to certain additional risks. Rising interest rates tend to extend the duration of mortgage-related securities, making them more sensitive to changes in interest rates. As a result, when holding mortgage-related securities in a period of rising interest rates, a Fund may exhibit additional volatility. In addition, mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of a Fund because it will have to reinvest that money at the lower prevailing interest rates.

The Morningstar RatingTM for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. Ratings for other share classes may differ. For current performance, please view the Performance page of the web site or call 800.395.3807.
