Example

The following example is intended to help you compare the cost of investing in the Fund’s Investor Shares with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. This example assumes that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


1 Year	3 Years	5 Years	10 Years
$24	$74	$130	$293

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests primarily in a diversified group of high-yielding, higher-risk corporate bonds—commonly known as “junk bonds”—with medium- and lower-range credit-quality ratings. The Fund invests at least 80% of its assets in corporate bonds that are rated below Baa by Moody’s Investors Service, Inc. (Moody’s); have an equivalent rating by any other independent bond-rating agency; or, if unrated, are determined to be of comparable quality by the Fund’s advisor.

The Fund may not invest more than 20% of its assets in any of the following, taken as a whole: bonds with credit ratings lower than B or the equivalent, convertible securities, preferred stocks, and fixed and floating rate loans of medium- to lower-range credit quality. The loans in which the Fund may invest will be rated Baa or below by Moody’s; have an equivalent rating by any other independent bond-rating agency; or, if unrated, are determined to be of comparable quality by the Fund’s advisor. The Fund’s high-yield bonds and loans mostly have short- and intermediate-term maturities.

Principal Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund’s performance:

• Credit risk, which is the chance that a bond or loan issuer will fail to pay interest and principal in a timely manner or that negative perceptions of the issuer’s ability to make such payments will cause the price of that bond or loan to decline. Credit risk should be high for the Fund because it invests primarily in bonds and loans with medium- and lower-range credit-quality ratings.

• Income risk, which is the chance that the Fund’s income will decline because of falling interest rates. Income risk is generally high for short-term bond funds and moderate for intermediate-term bond funds, so investors should expect the Fund’s monthly income to fluctuate accordingly.

• Interest rate risk, which is the chance that bond or loan prices will decline because of rising interest rates. Interest rate risk should be moderate for the Fund because it invests primarily in short- and intermediate-term bonds, whose prices are less sensitive to interest rate changes than are the prices of long-term bonds.

• Liquidity risk, which is the chance that the Fund may not be able to sell a security in a timely manner at a desired price. Liquidity risk is generally low for short-term corporate bonds and loans and moderate for intermediate-term corporate bonds and loans.

• Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

Because of the speculative nature of junk bonds, you should carefully consider the risks associated with this Fund before you purchase shares.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
