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 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 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 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. Because the Fund is new, no portfolio turnover information has been provided.

Principal Investment Strategies

Under normal circumstances, the Conservative Income Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in U.S. dollar-denominated debt securities that the Fund's sub-adviser (the Sub-Adviser) believes present minimal credit risks to the Fund.

Under normal market conditions, the Fund will primarily invest in short-term US dollar denominated debt securities, including: (i) commercial paper, corporate bonds and asset-based securities of U.S. and foreign issuers; (ii) certificates of deposit, time deposits, bankers' acceptances, bank notes, and other obligations of U.S. savings and loan and thrift institutions, US banks or US branches or non-US branches of foreign banks; (iii) short-term obligations issued by state and local governments; (iv) U.S. Treasury obligations and obligations issued or guaranteed as to principal and interest by agencies or instrumentalities of the U.S. Government; and (v) obligations of foreign governments (including Canadian and Provincial Government and Crown Agency obligations). The Fund may also enter into fully-collateralized repurchase agreements. Although the Fund may invest in securities with any maturity or duration, the Fund generally seeks to maintain a weighted average maturity of 90 days or less.

Under normal circumstances, the Fund will invest at least 25% of its assets in securities issued by companies in the financial services industry, but may invest less than 25% of its assets in this industry as a temporary defensive measure.

The Fund uses a Sub-Adviser to manage the Fund's portfolio under the general supervision of SEI Investments Management Corporation, the Fund's adviser (SIMC or the Adviser). Through analysis of both macroeconomic factors and individual company attributes, the Sub-Adviser seeks to invest in securities that are marketable and liquid, offer competitive yields, and are of issuers that represent low credit risk. In selecting securities, the Sub-Adviser also considers factors such as the anticipated level of interest rates and the maturity of individual securities relative to the maturity of the Fund as a whole.

The Fund is not a money market fund and does not seek to maintain a stable net asset value.

Principal Risks

Asset-Backed Securities Risk — Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities. Securitization trusts generally do not have any assets or sources of funds other than the receivables and related property they own, and asset-backed securities are generally not insured or guaranteed by the related sponsor or any other entity. Asset-backed securities may be more illiquid than more conventional types of fixed income securities that the Fund may acquire.

Concentration Risk — A downturn in the financial services industry would impact the Fund more than a portfolio that does not concentrate in securities issued by companies in the financial services industry.

Corporate Fixed Income Securities Risk — Corporate fixed income securities respond to economic developments, especially changes in interest rates, as well as perceptions of the creditworthiness and business prospects of individual issuers.

Credit Risk — The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation.

Extension Risk — The risk that rising interest rates may extend the duration of a fixed income security, typically reducing the security's value.

Financial Services Industry Risk — The Fund's portfolio is concentrated in investments in securities issued by companies in the financial services industry. The financial services industry is subject to extensive government regulation. Profitability is largely dependent on the availability and cost of capital and can fluctuate significantly when interest rates change. Financial services companies are highly dependent on short-term interest rates and typically will be adversely affected by economic downturns or changes in banking regulations.

Fixed Income Market Risk — The prices of the Fund's fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the Fund's fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. In the case of foreign securities, price fluctuations will reflect international economic and political events, as well as changes in currency valuations relative to the U.S. dollar. In response to these events, the Fund's value may fluctuate and/or the Fund may experience increased redemptions from shareholders, which may impact the Fund's liquidity or force the Fund to sell securities into a declining or illiquid market.

Foreign Issuer Risk — The risk that issuers in foreign countries face political and economic events unique to such countries. These events will not necessarily affect the U.S. economy or similar issuers located in the U.S.

Interest Rate Risk — The risk that a rise in interest rates will cause a fall in the value of fixed income securities, including U.S. Government securities, in which the Fund invests. Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. A low interest rate environment may present greater interest rate risk because there may be a greater likelihood of rates increasing and rates may increase more rapidly.

Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. The Fund's net asset value per share will fluctuate with the market prices of its portfolio securities. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole. Although the Fund may have an investment portfolio of short-term debt securities that is similar to the investment portfolios of many money market funds, the Fund is not a money market fund, does not seek to maintain a stable net asset value per share, and does not provide investors with the same regulatory protections as a money market fund. Under normal conditions, the Fund's investments may be more susceptible than a money market fund to interest rate risk, valuation risk, credit risk and other risks relevant to the Fund's investments. Certain of the Fund's investments may not be permitted investments of a money market fund.

Opportunity Risk — The risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in other investments.

Prepayment Risk — The risk that, in a declining interest rate environment, fixed income securities with stated interest rates may have the principal paid earlier than expected, requiring the Fund to invest the proceeds at generally lower interest rates.

Repurchase Agreement Risk — Although the Fund's repurchase agreement transactions will be fully collateralized at all times, they generally create leverage and involve some counterparty risk to the Fund whereby a defaulting counterparty could delay or prevent the Fund's recovery of collateral.

U.S. Government Securities Risk — Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency's own resources.

Investing in the Fund involves risk, and there is no guarantee that the Fund will achieve its investment goal. You could lose money on your investment in the Fund, just as you could with other investments.

Performance Information

The Fund is new, and therefore has no performance history. Once the Fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Fund by showing the variability of the Fund's return based on net assets and comparing the Fund's performance to a broad measure of market performance.
