EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund will incur 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 higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 148% of the average of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Intermediate Duration Credit Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in investment grade US dollar-denominated fixed income instruments. The Fund will primarily invest in (i) US and foreign corporate obligations; (ii) fixed income securities issued by sovereigns or agencies in both developed and emerging foreign markets; (iii) obligations of supranational entities; (iv) debt obligations issued by state, provincial, county, or city governments or other municipalities, as well as those of public utilities, universities and other

quasi‑governmental bodies; and (v) securities issued or guaranteed by the U.S. Government and its agencies and instrumentalities.

Although the Fund will primarily invest in the instruments described above, it may also invest in futures contracts, options on securities, currencies or indexes and swaps, including interest rate swaps, single security swaps, swaps on an index of securities or credit default swaps. The Fund will primarily use such derivatives for hedging purposes to attempt to manage the Fund’s exposure to changes in interest rate duration and related investment risks resulting from the interaction of interest rate changes over time and the current value of fixed income securities. The Fund will typically use options and swaps in an attempt to either mitigate the Fund’s overall level of risk or to gain exposure to a particular fixed income security or segment of the fixed income market. Interest rate swaps, credit default swaps and total return swaps may be used to manage various portfolio exposures including, but not limited to, interest rate risk and credit risk. When the Fund seeks to take an active long or short position with respect to the likelihood of an event of default of a security or basket of securities, the Fund may use credit default swaps. The Fund may buy credit default swaps in an attempt to manage credit risk where the Fund has credit exposure to an issuer and the Fund may sell credit default swaps to more efficiently gain credit exposure to such security or basket of securities. The Fund may also, to a lesser extent, invest in shares of exchange-traded funds (ETFs) or mutual funds to obtain exposure to certain fixed income markets.

Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security’s price to changes in interest rates. For example, if a fixed income security has a five-year duration, it will decrease in value by approximately 5% if interest rates rise 1% and increase in value by approximately 5% if interest rates fall 1%. Fixed income instruments with higher duration typically have higher risk and higher volatility. Although the Fund may invest in securities with any maturity or duration, the Fund under normal circumstances will seek to maintain an effective average duration between three and ten years.

The Fund uses a multi-manager approach under the general supervision of SEI Investments Management Corporation (SIMC or the Adviser), allocating its assets among one or more sub-advisers (each, a Sub-Adviser and collectively, the Sub-Advisers) using different investment strategies designed to provide current income consistent with the preservation of capital. Due to its investment strategy, the Fund may buy and sell securities and other instruments frequently.
