Fund objective

Seeks high total investment return through a combination of current income and capital appreciation

Investment strategy

The fund invests primarily in high-quality corporate and U.S. government bonds, generally maintaining an average effective maturity of 10-years or less.
Portfolio construction is driven by bottom-up security selection and top-down macroeconomic analysis.
The fund can pursue higher returns than core fixed-income funds due to its flexibility to invest up to 20% of assets in below-investment-grade, and up to 10% in non-dollar and emerging market debt.
The portfolio is structured with benchmark-aware risk and return objectives but uses tactical investments in non-benchmark sectors as a key source of potential return.
The fund manages interest rate risk by generally maintaining duration +/- 2 years relative to the benchmark.
Managers believe the resulting portfolio is well diversified and positioned to generate strong long-term risk-adjusted investment performance.

Risks

Mutual funds that invest in bonds can lose their value as interest rates rise, and an investor can lose principal.
Because the fund can invest a significant percentage of assets in debt securities that are rated below investment grade, the value of fund shares can be adversely affected by changes in economic conditions or other circumstances. These events could reduce or eliminate the capacity of issuers of these securities to make principal and interest payments.
Lower-rated debt securities have speculative characteristics because of the credit risk of their issuers and may be subject to greater price volatility than higher-rated investments. In addition, the secondary market for these securities may lack liquidity which, in turn, may adversely affect the value of these securities and that of the fund.
Because the fund can invest a significant percentage of assets in foreign securities, the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant.
The fund is subject to currency risk, which is the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may cause the value of a fund’s investments to decline. Funds that invest in securities denominated in, or receive revenues in, foreign currency are subject to currency risk. Accordingly, the purchase of fund shares should be viewed as a long-term investment.
