The Fund will pay 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 61% of the average value of its portfolio.

Under normal circumstances, the Fund will seek to generate "real return" (i.e., total returns that exceed the rate of inflation over a full market cycle, regardless of market conditions) by selecting investments from among a broad range of asset classes, including fixed income and equity securities and commodity investments. The asset classes used and the Fund's allocations among asset classes will be determined based on SEI Investments Management Corporation's (SIMC's) or the sub-advisers' (each, a Sub-Adviser and collectively, the Sub-Advisers) views of fundamental, technical or valuation measures. The Fund's allocations among asset classes may be adjusted over short periods of time. At any point in time, the Fund may be diversified across many asset classes or concentrated in a limited number of asset classes. The Fund may obtain its exposures to the asset classes by investing directly in securities and other investments or indirectly through the use of other pooled investment vehicles and derivative instruments.

The Fund uses a multi-manager approach under the general supervision of SIMC, allocating its assets among one or more Sub-Advisers using different investment strategies. SIMC may also directly manage a portion of the Fund's portfolio.

Equity securities may include common or preferred stocks, warrants, rights, depositary receipts, equity-linked securities and other equity interests. The Fund may invest in securities of issuers of any market capitalization and may invest in both foreign and domestic equity securities. In addition to direct investment in securities and other instruments, the Fund may invest in affiliated and unaffiliated funds, including open-end funds, closed-end funds and exchange-traded funds (ETFs). The Fund may also invest in real estate investment trusts (REITs) and U.S. and non-U.S. real estate companies.

The Fund may invest in fixed income securities that are investment or non-investment grade (also known as junk bonds), U.S.- or foreign-issued (including emerging markets), and corporate- or government-issued. The Fund may invest in a wide range of fixed income investments, including obligations of U.S. and foreign commercial banks, such as certificates of deposit, time deposits, bankers' acceptances and bank notes, obligations of foreign governments, U.S. and foreign corporate debt securities, including commercial paper, and fully collateralized repurchase and reverse repurchase agreements with highly rated counterparties (those rated A or better) and securitized issues such as mortgage-backed securities, asset-backed securities, commercial mortgage-backed securities and collateralized debt obligations. The Fund's fixed income investments may also include U.S. Treasury obligations, obligations issued by agencies or instrumentalities of the U.S. Government (including obligations not guaranteed by the U.S. Treasury), such as obligations issued by U.S. Government sponsored entities, Treasury Inflation Protected Securities (TIPS) and other inflation-linked debt securities, and municipal bonds and debentures. The Fund may invest in fixed, variable and floating rate fixed income instruments. The Fund's portfolio and the Fund's investments in particular fixed income securities are not subject to any maturity or duration restrictions. The Fund may also enter into repurchase or reverse repurchase agreements with respect to its investment in the fixed income securities listed above and may use the cash received to enter into a short position on U.S. Treasury bonds.

A portion of the Fund's assets may also be invested in commodity investments to provide exposure to the investment returns of the commodities markets. Commodity investments include notes with interest payments that are tied to an underlying commodity or commodity index, ETFs or other exchange-traded products that are tied to the performance of a commodity or commodity index or other types of investment vehicles or instruments that provide returns that are tied to commodities or commodity indices. The Fund may also invest in equity securities of issuers in commodity-related industries.

The Fund may also seek to gain exposure to the commodity markets, in whole or in part, through investments in a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (Subsidiary). The Subsidiary, unlike the Fund, may invest to a significant extent in commodities, commodity contracts, commodity investments and derivative instruments. The Subsidiary may also invest in other instruments in which the Fund is permitted to invest, either as investments or to serve as margin or collateral for its derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. The Subsidiary is advised by SIMC

The Fund, either directly or through its investment in the Subsidiary, may also purchase or sell futures contracts, options, forward contracts and swaps to obtain the Fund's desired exposure to an asset class or for return enhancement or hedging purposes. Interest rate futures contracts are primarily used to hedge interest rate risk in the Fund's U.S. bond holdings. Commodity futures contracts are primarily used to obtain exposure to a diversified set of commodity markets. Interest rate swaps may further be used to manage the Fund's interest rate risk. Swaps on indices may be used to manage the inflation-adjusted return of the Fund. 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 a security or basket of securities. Options may be used to gain exposure to or hedge exposures in the equity and commodity markets. Foreign currency forward rate agreements may be used to hedge all or a portion of the currency risk resulting from investments in non-U.S. equity and fixed income securities.

The Fund may invest in U.S. dollar and non-U.S. dollar denominated securities. The Sub-Adviser(s) may also seek to enhance the Fund's return by actively managing the Fund's foreign currency exposure. In managing the Fund's currency exposure, the Sub-Adviser(s) may buy and sell currencies (i.e., take long or short positions) using futures and foreign currency forward contracts. The Fund may take long and short positions in foreign currencies in excess of the value of the Fund's assets denominated in a particular currency or when the Fund does not own assets denominated in that currency. The Fund may also engage in currency transactions in an attempt to take advantage of certain inefficiencies in the currency exchange market, to increase its exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one currency to another. In managing the Fund's currency exposure for foreign securities, the Sub-Adviser(s) may buy and sell currencies for hedging or for speculative purposes.

The Sub-Adviser(s) may engage in short sales in an attempt to capitalize on equity securities that it believes will underperform the market or their peers. When a Sub-Adviser(s) sells securities short, it may invest the proceeds from the short sales in an attempt to enhance returns. This strategy may effectively result in the Fund having a leveraged investment portfolio, which results in greater potential for loss

Due to its investment strategy, the Fund may buy and sell securities frequently.

The success of the Fund's investment strategy depends both on SIMC's selection of the Sub-Adviser(s) and allocation of assets to such Sub-Adviser(s). The Sub-Adviser(s) may be incorrect in assessing market trends or the value or growth capability of particular securities or asset classes. In addition, the methodology by which SIMC allocates the Fund's assets to the Sub-Adviser(s) may not achieve desired results and may cause the Fund to lose money or underperform other comparable mutual funds.

The Sub-Adviser(s) and any underlying funds in which it invests may apply any of a variety of investment strategies and may invest in a broad range of asset classes, securities and other investments to achieve those investment strategies. The principal risks of using such investment strategies and making investments in such asset classes, securities and other investments are set forth below. Because an underlying fund's use of an investment strategy or investment in an asset class, security or other investment is subject to the same or similar risks as the Fund's use of such strategy or investment in such asset class, security or other investment, the term "the Fund" in the paragraphs below collectively refers to both the Fund and each underlying fund.

Asset-Backed Securities Risk — Payment of principal and interest on asset-backed securities is dependent largely on cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets.

Below Investment Grade Securities (Junk Bonds) Risk — Fixed income securities rated below investment grade (junk bonds) involve greater risks of default or downgrade and are more volatile than investment grade securities because the prospect for repayment of principal and interest of many of these securities is speculative. Because these securities typically offer a higher rate of return to compensate investors for these risks, they are sometimes referred to as "high yield bonds," but there is no guarantee that an investment in these securities will result in a high rate of return. These risks may be increased in foreign and emerging markets.

Commodity Investments and Derivatives Risk — Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer's financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments.

Corporate Fixed Income Securities Risk — Corporate fixed income securities respond to economic developments, especially changes in interest rates, as well as to 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.

Currency Risk — As a result of the Fund's investments in securities or other investments denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund would be adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the U.S. or abroad.

Derivatives Risk — The Fund's use of futures contracts, forward contracts, options and swaps is subject to market risk, leverage risk, correlation risk and liquidity risk. Leverage risk, liquidity risk and market risk are described below. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. The Fund's use of forward contracts and swap agreements is also subject to credit risk and valuation risk. Valuation risk is the risk that the derivative may be difficult to value and/or may be valued incorrectly. Credit risk is described above. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument.

Equity Market Risk — The risk that stock prices will fall over short or extended periods of time.

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

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. 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 Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. These additional risks may be heightened with respect to emerging market countries since political turmoil and rapid changes in economic conditions are more likely to occur in these countries.

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

Inflation Protected Securities Risk — The value of inflation protected securities, including TIPS, will typically fluctuate in response to changes in "real" interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates reduced by the expected impact of inflation. In addition, interest payments on inflation-indexed securities will generally vary up or down along with the rate of inflation.

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.

Investment Company Risk — When the Fund invests in an investment company, including closed-end funds and ETFs, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company's expenses. Further, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund had invested directly in the underlying investments. For example, the lack of liquidity in an ETF could result in its value being more volatile than that of the underlying portfolio securities. Closed-end investment companies issue a fixed number of shares that trade on a stock exchange or over-the-counter at a premium or a discount to their net asset value. As a result, a closed-end fund's share price fluctuates based on what another investor is willing to pay rather than on the market value of the securities in the fund.

Investment in the Subsidiary Risk — The Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act) and, unless otherwise noted in this prospectus, is not subject to all of the investor protections of the 1940 Act. Thus, the Fund, as an investor in the Subsidiary, will not have all of the protections offered to investors in registered investment companies. In addition, changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or the Subsidiary to operate as intended and could negatively affect the Fund and its shareholders.

Leverage Risk — The Fund's use of derivatives may result in the Fund's total investment exposure substantially exceeding the value of its portfolio securities and the Fund's investment returns depending substantially on the performance of securities that the Fund may not directly own. The use of leverage can amplify the effects of market volatility on the Fund's share price and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The Fund's use of leverage may result in a heightened risk of investment loss.

Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and price that the Fund would like. The Fund may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance.

Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole.

Mortgage-Backed Securities Risk — Mortgage-backed securities are affected by, among other things, interest rate changes and the possibility of prepayment of the underlying mortgage loans. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations.

Municipal Securities Risk — Municipal securities, like other fixed income securities, rise and fall in value in response to economic and market factors, primarily changes in interest rates, and actual or perceived credit quality. Rising interest rates will generally cause municipal securities to decline in value. Longer-term securities usually respond more sharply to interest rate changes than do shorter-term securities. A municipal security will also lose value if, due to rating downgrades or other factors, there are concerns about the issuer's current or future ability to make principal or interest payments. State and local governments rely on taxes and, to some extent, revenues from private projects financed by municipal securities, to pay interest and principal on municipal debt. Poor statewide or local economic results or changing political sentiments may reduce tax revenues and increase the expenses of municipal issuers, making it more difficult for them to repay principal and to make interest payments on securities owned by the Fund. Actual or perceived erosion of the creditworthiness of municipal issuers may reduce the value of the Fund's holdings. As a result, the Fund will be more susceptible to factors which adversely affect issuers of municipal obligations than a mutual fund which does not have as great a concentration in municipal obligations. Any changes in the financial condition of municipal issuers also may adversely affect the value of the Fund's securities.

Non-Diversified Risk — The Fund is non-diversified, which means that it may invest in the securities of relatively few issuers. As a result, the Fund may be more susceptible to a single adverse economic or political occurrence affecting one or more of these issuers and may experience increased volatility due to its investments in those securities.

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.

Portfolio Turnover Risk — Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities.

Prepayment Risk — The risk that, with declining interest rates, 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.

Real Estate Industry Risk — Securities of companies principally engaged in the real estate industry may be subject to the risks associated with direct ownership of real estate. Risks commonly associated with the direst ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions.

REITs Risk — REITs are trusts that invest primarily in commercial real estate or real estate-related loans. The Fund's investments in REITs will be subject to the risks associated with the direct ownership of real estate, which are discussed above. Some REITs may have limited diversification and may be subject to risks inherent in financing a limited number of properties.

Short Sales Risk — A short sale involves the sale of a security that the Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. Short sales expose the Fund to the risk that it will be required to buy the security sold short (also known as "covering" the short position) at a time when the security has appreciated in value, thus resulting in a loss to the Fund that is potentially unlimited. Investing in short sales may also cause the Fund to incur expenses related to borrowing securities. Reinvesting proceeds received from short selling may create leverage, which can amplify the effects of market volatility on the Fund's share price.

Small and Medium Capitalization Risk — The risk that small and medium capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter or listed on an exchange.

Tax Risk — The Fund may gain most of its exposure to the commodities markets through its investment in the Subsidiary, which invests in commodity investments and derivative instruments. To the extent the Fund invests in such instruments directly, it will seek to restrict its income from commodity-linked derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10% of its gross income (when combined with its other investments that produce non-qualifying income) to comply with certain qualifying income tests necessary for the Fund to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended. The tax treatment of certain commodity-linked derivative instruments may be affected by future regulatory or legislative changes that could affect the character, timing and/or amount of the Fund's taxable income or gains and distributions.

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.

Loss of money is a risk of investing in the Fund.

As of October 14, 2014, the Class Y Shares of the Fund had not commenced operations.

The bar chart and the performance table below provide some indication of the risks of an investment in the Class Y Shares of the Fund by comparing the Fund's Class A Shares' performance from year to year for the past calendar year and by showing how the Fund's Class A Shares' average annual returns for 1 year and since the Fund's Class A Shares' inception compared with those of a broad measure of market performance. The Fund's Class A Shares are offered in a separate prospectus. Because Class Y Shares are invested in the same portfolio of securities, returns for Class Y Shares would have been substantially similar to those of Class A Shares, shown here, and would have differed only to the extent that Class Y Shares have lower total annual fund operating expenses than Class A Shares. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. For current performance information, please call 1-800-DIAL-SEI.

Best Quarter: 1.62% (09/30/13)

Worst Quarter: -6.08% (06/30/13)

The Fund's Class A total return (pre-tax) from January 1, 2014 to June 30, 2014, was 2.66%.

The Fund's Class Y Shares have not yet commenced operations, and therefore do not have performance history for a full calendar year. This table compares the Fund's Class A Shares' average annual total returns for the period ended December 31, 2013 to those of an appropriate broad based index and the Fund's 70/20/10 Blended Benchmark, which consists of the Barclays 1-5 Year U.S. TIPS Total Return Index (70%), the Dow Jones UBS Commodity Index (20%) and the Russell 1000 Low Volatility Total Return Index (10%). The Fund's Blended Benchmark is designed to provide a useful comparison to the Fund's overall performance and more accurately reflects the Fund's investment strategy than the broad-based index.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.
