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 Balanced Fund’s performance. During the most recent fiscal year, the Balanced Fund’s portfolio turnover rate was 12% of the average value of its portfolio. Principal Investment Strategies The Balanced Fund operates under a fund of funds structure. The Balanced Fund invests substantially all of its assets in the Income Fund, Large Cap Core Plus Fund (the “Large Cap Core Plus Fund”) (formerly, the Wilshire Large Cap Core 130/30 Fund) and International Equity Fund. As a matter of investment policy, 30% to 50% of the value of its assets will be invested in the Income Fund, 0% to 55% of the value of its assets will be invested in the Large Cap Core Plus Fund and 0% to 25% of the value of its assets will be invested in the International Equity Fund. Under normal circumstances, the Balanced Fund’s target asset mix is 65% equity securities and 35% fixed income securities. In addition, the Balanced Fund may invest in certain individual securities, including money market instruments and U.S. government securities.   For the Income Fund, the following describes the types of securities in which the Income Fund is permitted to invest:   The Income Fund invests, under normal circumstances, at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in fixed income securities. These securities are primarily U.S. investment grade fixed income securities, including government and corporate securities, mortgage and asset-backed securities, which are generally pass through securities.   The Income Fund invests at least 75% of its total assets in:   <table align="center" cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: top"> <td style="width: 12px; text-align: justify"> </td> <td style="width: 24px; text-align: justify">•</td> <td style="text-align: justify">investment grade, publicly offered debt securities, including mortgage-backed and other asset-backed securities (within the four highest ratings as determined by Moody’s Investors Service (“Moody’s”), Standard & Poor’s (“S&P”) or an equivalent rating at the time of purchase)</td></tr> </table>   <table align="center" cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: top"> <td style="width: 12px; text-align: justify"> </td> <td style="width: 24px; text-align: justify">•</td> <td style="text-align: justify">securities issued or guaranteed by the U.S. government or its agencies</td></tr> </table>   <table align="center" cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: top"> <td style="width: 12px; text-align: justify"> </td> <td style="width: 24px; text-align: justify">•</td> <td style="text-align: justify">high quality commercial paper (within the two highest grades as determined by both Moody’s and S&P or an equivalent rating), repurchase and reverse repurchase agreements, time deposits with maturities less than seven days and cash or cash equivalents</td></tr> </table>   <table align="center" cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: top"> <td style="width: 12px"> </td> <td style="width: 24px">•</td> <td style="text-align: justify">high grade U.S. dollar-denominated debt obligations of foreign governments, foreign corporations, foreign branches of U.S. banks and foreign banks (limited to the four highest ratings as determined by Moody’s, S&P or an equivalent rating at the time of purchase and to 15% of the Income Fund’s total assets)</td></tr> </table>   <table align="center" cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: top"> <td style="width: 12px"> </td> <td style="width: 24px">•</td> <td style="text-align: justify">highest quality non U.S. dollar-denominated debt obligations of foreign issuers (limited to the four highest ratings as determined by Moody’s, S&P or an equivalent rating at the time of purchase) which are fully hedged back into U.S. dollars and do not exceed 15% of the Income Fund’s total assets</td></tr> </table>   Generally, the average duration of the U.S. portion of the Income Fund will range within 25% of the Barclays Capital Aggregate Bond Index’s duration. There are no maximum maturity limits on individual securities. For defensive purposes, the duration and maturity of the Income Fund may be shortened. The Income Fund will maintain a high grade average quality for the portfolio (third highest rating as determined by Moody’s, S&P or an equivalent rating).   Up to 25% of the Income Fund’s total assets may be invested in securities not described above, including preferred stock, convertible securities, securities carrying warrants to purchase equity securities, U.S. dollar-denominated debt obligations of U.S. and non U.S. issuers rated below A (by Moody’s, S&P or an equivalent rating) and non U.S. debt obligations rated below the highest quality (as determined by Moody’s, S&P or an equivalent rating) and derivatives.   For the Large Cap Core Plus Fund, the following describes the types of securities in which the Large Cap Core Plus Fund is permitted to invest:   <table align="center" cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: top"> <td style="width: 12px; text-align: justify"> </td> <td style="width: 24px; text-align: justify">•</td> <td style="text-align: justify">The Large Cap Core Plus Fund normally invests at least 85% of its net assets in large cap securities.

In addition, investing in the Balanced Fund involves the following risks:   Asset Allocation Risk. Although asset allocation among different asset categories and investment strategies generally reduces risk and exposure to any one category or strategy, the risk remains that the Adviser may favor an asset category or investment strategy that performs poorly relative to other asset categories and investment strategies.   Credit Risk. For debt securities, credit risk is the possibility that an issuer or counterparty to a contract will fail to make timely payments of interest or principal to a fund. The credit risk of the Fund depends on the credit quality of its underlying securities. In general, for debt securities, the lower the credit quality of a fund’s securities, the higher a fund’s risk, all other factors such as maturity being equal.   Interest Rate Risk. For debt securities, interest rate risk is the possibility that the price will fall because of changing interest rates. In general, debt securities’ prices rise or fall inversely to changes in interest rates. If interest rates rise, bond prices generally fall; if interest rates fall, bond prices generally rise. In addition, for a given change in interest rates, longer-maturity bonds fluctuate more in price (gaining or losing more in value) than shorter-maturity bonds.   Prepayment Risk. Mortgage-backed securities are subject to the risk of unanticipated prepayments of principal with respect to mortgages in the security’s underlying pool of assets. While principal prepayments are passed through to the holders of the securities, prepayments also reduce the future payments on such securities and may reduce their value. Mortgage-backed securities are subject to the risk that an unexpected rise in interest rates will extend the life of a mortgage-backed security beyond the expected prepayment time, typically reducing the security’s value. Mortgage-backed securities are subject to the risk that an unexpected decline in interest rates will contract the life of a mortgage-backed security, thereby affecting its prepayment schedule, which may affect the value of the security.   Reinvestment Risk. During periods of falling interest rates, a debt security with a high stated interest rate may be prepaid (or “called”) prior to its expected maturity date. If, during periods of falling interest rates, a debt security with a high stated interest rate is called, the unanticipated proceeds would likely be invested at lower interest rates, and a fund’s income or yield may decline. Call provisions, which may lead to reinvestment risk, are most common for intermediate- and long-term municipal, corporate and mortgage-backed securities. To the extent securities subject to call were acquired at a premium, the potential for appreciation in the event of a decline in interest rates may be limited and may even result in losses.   Recent Market Events Risk. The equity and debt capital markets in the U.S. and elsewhere have experienced unprecedented volatility in the past several years. This financial crisis had caused a significant decline in the value and liquidity of many securities and may create a higher degree of volatility in the net asset values of many mutual funds, including the Fund. Because these events are unprecedented, it is difficult to predict their magnitude or duration. Changes in market conditions will not have the same impact on all types of securities.   In response to the crisis, the U.S. Government and the Federal Reserve have taken steps to support financial markets. The withdrawal of this support could negatively impact the value and liquidity of certain securities. In addition, legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.   By investing in the Balanced Fund, an investor also assumes the same types of risks, either directly, or indirectly, as investing in the Income Fund, International Equity Fund and the Large Cap Core Plus Fund. For the Income Fund, such risks include “Credit Risk,” “Interest Rate Risk,” “Prepayment Risk,” “Reinvestment Risk” and “Recent Market Events Risk,” as described above and the following risks:   Portfolio Turnover Risk. A Fund that trades aggressively will experience high portfolio turnover and relatively high brokerage and other transaction costs. Such transaction costs may lower a fund’s effective investment return.   Portfolio Strategy Risk. The investment performance of the Income Fund is in part dependent upon a sub-adviser’s skill in making appropriate investments. To the extent that a fund’s investments differ from the portfolio represented by the benchmark, there exists the potential for volatility of the return of a fund relative to its index. As the industry and sector composition of the market or index changes over time, the implementation of a fund’s strategy can lead to substantial differences in the sector or industry allocation of a fund relative to the market or index.   Liquidity Risk. The Income Fund may invest in certain securities that may be difficult or impossible to sell at a certain time and at a price that the Fund finds to be favorable. The Income Fund may have to accept an unfavorable price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on portfolio management or investment performance.   Currency Risk. Non U.S. dollar-denominated securities are subject to fluctuations in the exchange rates between the U.S. dollar and foreign currencies which may negatively affect an investment. Adverse changes in exchange rates may erode or reverse any gains produced by foreign currency denominated investments, and may widen any losses.   Derivatives Risk. When a fund uses derivatives (securities whose value is based upon the value of another security or an index) to hedge positions in the portfolio, any loss generated by the derivative security should be substantially offset by gains on the hedged investment and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. To the extent that a derivative is not used as a hedge (i.e., for speculation), a fund is directly exposed to the potential gains and losses of that derivative. Gains and losses from non hedging derivative positions may be substantially greater than the derivative’s original cost. To the extent a fund uses derivatives, a fund will (to the extent required by applicable law) either segregate cash or liquid assets in the prescribed amounts or “cover” its future obligations under the transaction, such as by holding an offsetting investment.   Valuation Risk. A fund may invest in securities that are difficult to value and may inadvertently value certain of its securities at a higher price than the market will bear.   Foreign Investment Risk. Foreign investments often involve risks such as political instability, differences in financial reporting standards and less stringent regulation of securities markets. These risks are magnified in less-established, emerging markets.   For the Large Cap Core Plus Fund, such risks include “Derivatives Risk,” “Recent Market Events Risk” and “Portfolio Turnover Risk,” as described above and the following risks:   Equity Risk. The principal risk of investing in the Fund is equity risk. This is the risk that the prices of stocks held by the Fund will change due to general market and economic conditions, perceptions regarding the industries in which the companies participate, and each company’s particular circumstances. Equity investments, including common stocks, tend to be more volatile than bonds and money market instruments. The value of the Fund’s shares will go up and down due to movement in the collective returns of the individual securities held by the Fund. Because common stocks are subordinate to preferred stocks in a company’s capital structure, in a company liquidation, the claims of secured and unsecured creditors and owners of bonds and preferred stocks take precedence over the claims of common stock shareholders.   Multi-Managed Fund Risk. The Fund is a multi-managed fund with multiple sub-advisers who employ different strategies. As a result, the Fund may have buy and sell transactions in the same security on the same day. In addition, at any given time, the Fund may have long and short positions in the same security.   Short Sale Risk. Short sales involve costs and risk. If a security sold short increases in price, the Large Cap Core Plus Fund may need to cover its short position at a higher price than the short sale price, resulting in a loss. The Large Cap Core Plus Fund will have substantial short positions and must borrow those securities to make delivery to the buyer. The Large Cap Core Plus Fund may not be able to borrow a security that it needs to deliver or it may not be able to close out a short position at an acceptable price and may need to sell related long positions before it had intended to do so. As a result, the Large Cap Core Plus Fund may not be able to successfully implement its short sale strategy due to the limited availability of desired securities or for other reasons and the amount the Large Cap Core Plus Fund could lose on a short sale is theoretically unlimited.   ETF Risk. ETFs in which the Fund may invest involve certain inherent risks generally associated with investments in a portfolio of common stocks, including the risk that the general level of stock prices may decline, thereby adversely affecting the value of each unit of the ETF. Moreover, an ETF may not fully replicate the performance of its benchmark index because of the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of stocks held. Investing in ETFs, which are investment companies, may involve duplication of advisory fees and certain other expenses.   Real Estate Investment Trust Risk. The Large Cap Core Plus Fund may invest in REITs, which carry with them many of the risks associated with direct ownership of real estate, including decline in property values, extended vacancies, increases in property taxes, and changes in interest rates. In addition, REITs are dependent upon management skills, may not be diversified, and may experience substantial cost in the event of borrower or lessee defaults. REITs are also subject to heavy cash flow dependency.   For the International Equity Fund, such risks include “Foreign Investment Risk,” “Equity Risk,” “Currency Risk,” “ETF Risk,” “Recent Events Risk,” “Portfolio Strategy Risk,” “Multi-Managed Fund Risk” and “Asset Allocation Risk,” as described above and the following risks:   Emerging Market Risk. Foreign investment risk may be particularly high to the extent the International Equity Fund invests in securities of issuers based in countries with developing economies (i.e., emerging markets). These securities may present market, credit, currency, liquidity, legal, political and other risks different from, or greater than, the risks of investing in developed foreign (non-U.S.) countries.   Market Risk. For equity securities, stock market movements will affect the International Equity Fund’s share price on a daily basis. Declines in value are possible because of declines in the stock market in general or because of a decline in the specific securities held by the International Equity Fund. There is also the possibility that the price of the security will fall because the market perceives that there is or will be a deterioration in the fundamental value of the issuer or poor earnings performance by the issuer. Market risk may affect a single company, industry, sector or the market as a whole. For debt securities, 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 bond market as a whole.   Small Cap Risk. Small-cap companies may lack the management experience, financial resources, product diversity and competitive strengths of larger companies, and may be traded less frequently. These companies may be in the developmental stage or may be older companies undergoing significant changes. Small-cap companies may also be subject to greater business risks and more sensitive to changes in economic conditions than larger more established companies. As a result, the prices of small-cap companies may rise and fall more sharply.   Investment Style Risk. During certain market conditions, a fund with a more specific investment style (such as value or growth) may perform less well than a fund that allows greater flexibility in the investment of assets. Performance The information below provides an illustration of how the Balanced Fund’s performance has varied over time.
