Dividend Yield is a financial ratio that shows how much a mutual fund pays out in dividends each year relative to value with maximum sales charges and without sales charges. The dividend yield is calculated by annualizing the last dividend and dividing it by the fund’s net asset value with maximum sales charges and without sales charges.

The 30-day Standardized Subsidized yields reflect fee waivers in effect. Without such fee waivers, yields would be reduced.  

Average Yield to Maturity is the total rate of return earned when a bond makes all interest payments and repays the original principal.

Distribution Yield is the calculation of cash flow for an investment vehicle, to calculate the distribution yield, the most recent distribution is multiplied by 12 to get an annualized total, which is then divided by the NAV.

The 30-day Standardized Unsubsidized yield does not reflect fee waivers.

A Note about Risk: The Fund is subject to the general risks associated with investing in debt securities, including market, credit, liquidity, and interest rate risk. The value of investments in debt securities will fluctuate in response to market movements. When interest rates rise, the prices of debt securities are likely to decline, and when interest rates fall, the prices of debt securities tend to rise. The Fund may invest substantially in high yield, lower-rated securities. These securities carry increased risks of price volatility, illiquidity, and the possibility of default in the timely payment of interest and principal. Moreover, the specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan's value. The Fund may invest in foreign or emerging market securities, which may be adversely affected by economic, political, or regulatory factors and subject to currency volatility and greater liquidity risk. The Fund may invest in derivatives, which are subject to greater liquidity, leverage, and counterparty risk. Certain of the Fund's derivative transactions may give rise to leverage risk. Leverage, including borrowing for investment purposes, may increase volatility in the Fund by magnifying the effect of changes in the value of the Fund's holdings. The use of leverage may cause investors in the Fund to lose more money in adverse environments than would have been the case in the absence of leverage. These factors may affect Fund performance.

Performance data quoted is historical. Past performance is not indicative of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Fund will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost.

The Overall Morningstar RatingTM is derived from a weighted average of the performance figures associated with a fund's three-, five-, and 10-year (as applicable) Morningstar RatingTM metrics. © Morningstar, Inc. All rights reserved. The information contained herein (1) is proprietary to Morningstar and/or its content providers; (2) may not be copied or distributed; and (3) is not warranted to be accurate, complete or timely. Neither Morningstar nor its content providers are responsible for any damages or losses arising from any use of this information.

Morningstar proprietary ratings reflect historical risk-adjusted performance. For each fund with at least a three-year history, Morningstar calculates a Morningstar RatingTM based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Load-waived ratings do not include any front-end sales charges (which are only available for certain defined contribution plans and certain mutual fund advisory programs) and should only be considered by investors who are not subject to sales loads. Not all funds with a load-waived rating may waive their front-end load. An investor should check with their advisor to determine if they are eligible to purchase the load-waived Class A share. The top 10% of the funds in an investment category receive 5 stars, 22.5% receive 4 stars, 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages). The Overall Morningstar rating is a weighted average of funds' three-, five-, and 10-year (as applicable) ratings. Past performance is no guarantee of future results. Morningstar Rating is for the Class A share only; other classes may have different performance characteristics.
