Enhanced Return Potential

The management team builds Core Plus on a diversified base of government, corporate and mortgage securities. They seek to increase risk-adjusted return potential by investing up to 35% of the portfolio in high-yield, emerging market and non-dollar issues.

Outperformance During the Credit Crisis

The management team recognized market risks and structured the portfolio appropriately prior to the Credit Crisis, providing Core Plus’ shareholders with positive returns while our intermediate-term bond competitors lost an average of -5.42%.1

A Proven Diversifier

Core Plus’ historically low correlation with the U.S. stock market makes it an ideal diversifier because the fund may help offset stock price movements.2 Surprisingly, competing intermediate-term bond funds are slightly correlated with stocks on average.1

Core Plus gained ground while others melted down during the Credit Crisis

A Note About Risk

The lower-rated securities in which the fund invests are subject to greater default and liquidity risk, because the issuers of high-yield securities are more sensitive to real or perceived economic changes. Generally, as interest rates rise, the value of the securities held in the fund will decline. The opposite is true when interest rates decline. International investing involves special risk considerations, including economic and political conditions, inflation rates and currency fluctuations. Investing in emerging markets may accentuate these risks. There is no guarantee that the investment objectives will be met. Dividends and yields represent past performance and there is no guarantee that they will continue to be paid.

Past performance is no guarantee of future results.

Diversification does not assure a profit nor does it protect against loss of principal.

Rating & Rankings

Loading Ratings and Rankings ...

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. Morningstar ratings are based upon Investor class of shares, unless otherwise indicated. The top 10% of funds in each 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. (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 RatingTM for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar RatingTM metrics. Past performance is no guarantee of future results.
