BEFORE YOU INVEST

Before considering an investment in the Fund, you should understand that you could lose money.


Floating rate funds are generally considered to have speculative characteristics that involve default risk of principal and interest, collateral impairment, non-diversification, borrower industry concentration, and limited liquidity.


Liquidity risk may also refer to the risk that the Fund may not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, unusually high volume of redemptions, or other reasons.

To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.


Foreign securities are subject to interest rate, currency exchange rate, economic, and political risks. These risks may be greater for emerging markets.


Funds that invest in bonds are subject to interest-rate risk and can lose principal value when interest rates rise. Bonds are also subject to credit risk, in which the bond issuer may fail to pay interest and principal in a timely manner.


S&P/LSTA Leveraged Loan Index is a broad index designed to reflect the performance of U.S. dollar facilities in the leveraged loan market.

Average Price is based on market value and is the market weighted average of all bonds held in the Fund's portfolio, including any zero coupon bonds.

The Morningstar Rating™ 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 (this does not include the effects of sales charges, loads, and redemption fees). The top 10% of products in each product category receive 5stars, 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.
