Lipper ratings for Total Return reflect funds’ historical total return performance relative to peers. Lipper ratings for Consistent Return reflect funds’ historical risk-adjusted returns, adjusted for volatility, relative to peers. The ratings are subject to change every month and are based on an equal-weighted average of percentile ranks for the Total Return or Consistent Return metrics over three-, five-, and ten-year periods (if applicable). The highest 20% of funds in each peer group are named Lipper Leader or a score of 5 for Total Return or Consistent Return, the next 20% receive a score of 4, the middle 20% are scored 3, the next 20% are scored 2, and the lowest 20% are scored 1. Lipper Leader ratings are not intended to predict future results, and Lipper does not guarantee the accuracy of this information. More information is available at www.lipperweb.com.

Price/Earnings ratio (P/E ratio) is a valuation ratio of a company’s current share price compared to its per-share earnings. P/E equals a company’s market value per share divided by earnings per share.

Beta is a measure of market-related risk. Less than one means the portfolio is less volatile than the index, while greater than one indicates more volatility than the index.

Price/Cash Flow is the measure of the market's expectations regarding a firm's future financial health. It is calculated by dividing price per share by cash flow per share.

Price/Book ratio (P/B ratio) is a ratio used to compare a stock's market value to its book value. It is calculated by dividing the current closing price of the stock by the latest quarter's book value per share.

Effective Duration – A bond’s sensitivity to interest rates, incorporating the embedded option features, such as call provisions. Bonds with longer durations experience greater price volatility than bonds with shorter durations.

1 To determine a fund’s Morningstar Rating™, funds with at least a three-year history are ranked in their categories by their Morningstar Risk-Adjusted Return scores. The top 10% receive 5 stars; the next 22.5%, 4 stars; the middle 35%, 3 stars; the next 22.5%, 2 stars; and the bottom 10% receive 1 star. The Risk-Adjusted Return accounts for variation in a fund’s performance (including the effects of all sales charges), placing more emphasis on downward variations and rewarding consistent performance. Other share classes may have different performance characteristics. © 2011 Morningstar, Inc. All Rights Reserved.

A bond credit rating assesses the financial ability of a debt issuer to make timely payments of principal and interest. Ratings of AAA (the highest), AA, A, and BBB are investment-grade quality. Ratings of BB, B, CCC, CC, C and D (the lowest) are considered below investment grade, speculative grade, or junk bonds. We have used ratings from Moody’s Investors Service. Where Moody’s ratings are not available, we have used Standard & Poor’s ratings. “NR” = not rated.

Important Information

Investments in the Fund carry risks, including possible loss of principal. Special risks may be associated with investments outside the United States, especially in emerging markets, including currency fluctuations, illiquidity and volatility. Investments in small capitalization companies may increase the risk of greater price fluctuations. Funds investing in bonds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds. The principal value of bonds will fluctuate relative to changes in interest rates, decreasing when interest rates rise. Investments in the Fund are not FDIC insured, nor are they deposits of or guaranteed by a bank or any other entity.

There is no guarantee that the Fund will meet its investment objectives.

Class I shares may not be available to all investors. Minimum investments for the I share class may be higher than those for other classes.

Before investing, carefully consider the Fund’s investment goals, risks, charges, and expenses. For a prospectus containing this and other information, contact your financial advisor or visit our literature library. Read it carefully before investing.

The S&P 500 Index, an unmanaged broad measure of the U.S. stock market, does not reflect sales charges.

The index is weighted by the market value of the bonds included in the index. The MSCI World Index is an unmanaged market-weighted index that consists of securities traded in 24 of the world’s most developed countries. Securities are listed on exchanges in the U.S., Europe, Canada, Australia, New Zealand, and the Far East. The index is calculated with net dividends reinvested, in U.S. dollars.
