Total rate of return consists of current income, which includes dividends, interest, discount accruals and capital appreciation. Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The table below does not reflect expenses that apply to separate accounts or related annuity contracts, and if such expenses were reflected, fees would be higher.

A higher portfolio turnover rate may indicate higher transaction costs. 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 151% of the average value of its portfolio. Principal Investment Strategies The Fund will invest in underlying affiliated funds (the “Underlying Funds”) and may invest in direct investments, including but not limited to exchange-traded products (“ETPs”), which include both exchange-traded funds and exchange-traded notes. Underlying Funds include mutual funds advised by Wilshire Associates, Inc., the Fund’s investment adviser (the “Adviser”), and currently include the Large Company Growth Portfolio, the Large Company Value Portfolio, the Small Company Growth Portfolio, the Small Company Value Portfolio and the Wilshire International Equity Fund. Under normal circumstances, the Fund’s target asset mix is 65% equity securities and 35% fixed income securities, with a range of 50% to 75% in equity securities and a range of 25% to 50% in fixed income securities. Under normal market conditions, the Fund invests in a diversified portfolio of global debt and equity securities of which at least 40% of the Fund’s net assets will be invested in non-U.S. investments and in at least three different countries. The Fund normally invests at least 25% of its assets in fixed income securities and at least 25% of its assets in equity securities. The Fund seeks income by investing in a combination of corporate, agency and government bonds and other debt securities of any maturity issued in numerous countries, including emerging markets countries. The Fund may also invest in high-yield bonds rated below investment grade credit quality. The Fund seeks capital appreciation by investing in equity securities of companies from a variety of industries located anywhere in the world, including emerging markets. The Fund employs Guggenheim Partners Investment Management, LLC (“Guggenheim”) with respect to the portion of the Fund investing directly in fixed income securities. With respect to the Fund’s direct investments in fixed income securities, Guggenheim will seek to achieve the Fund’s investment objective by primarily investing in a wide range of U.S. fixed income and other U.S. debt securities selected from a variety of sectors and credit qualities, that may include, but are not limited to, the following types of securities that Guggenheim believes offer attractive yield and/or capital appreciation potential: treasury, government, and agency securities (including those not backed by the full faith and credit of the U.S. government); asset-backed securities (including structured finance investments); collateralized mortgage obligations (both commercial and residential); mortgage-backed securities (both commercial and residential); collateralized debt obligations (including collateralized loan obligations and collateralized bond obligations); corporate securities; private placements; unregistered and restricted securities (consisting of securities eligible for resale pursuant to Rule 144A); mezzanine and preferred securities; convertible debt (which may result in equity received in a conversion or a workout); commercial paper; inflation-indexed bonds; structured notes; bank certificates of deposit; fixed time deposits; bank notes, bank loans (including, but not limited to, syndicated loans, secured and unsecured loans, bridge loans, debtor-in-possession (“DIP”) loans, revolving credit facilities and other floating rate corporate loans) and loan participations and assignments; bankers’ acceptances; municipal securities; credit linked notes; and asset-backed commercial paper. While the fund’s direct investments in fixed income securities are expected to be primarily U.S. fixed income securities, Guggenheim may also invest in non-U.S. fixed income securities including but not limited to the types listed above, if Guggenheim believes such investments are consistent with the Fund's investment objectives. The Fund may also seek to obtain exposure to the securities in which it invests through a variety of investment vehicles, principally closed-end funds, exchange-traded funds (“ETFs”) and other mutual funds. Guggenheim will use a relative value-based investment philosophy, which utilizes quantitative and qualitative analysis to seek to identify securities or spreads between securities that deviate from their perceived fair value and/or historical norms. Guggenheim’s investment philosophy is predicated upon the belief that thorough research and independent thought are rewarded with performance that has the potential to outperform benchmark indexes with the potential for lower correlation of returns as compared to such benchmark indexes. As an alternative to holding investments directly, the Fund may also obtain investment exposure through the limited use of certain types of derivatives transactions intended to replicate or modify the economic attributes associated with an investment in securities in which the Fund may invest directly, or manage risk. The fund's ability to make investments and manage certain risks using derivatives is, however, limited by the Investment Company Act of 1940, as amended. Derivatives may include, forward contracts and futures on single securities and narrow based securities indices, and options on a security, or group or index of securities, and certain currency transactions. The Fund may be exposed to certain additional risks should Guggenheim use derivatives as a means to synthetically implement the Fund's investment strategies. The Fund may use leverage to the extent permitted by applicable law by entering into reverse repurchase agreements for investment purposes. The Fund may also seek to obtain exposure to the securities in which it invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as forward commitments, buy backs and or dollar rolls and “To Be Announced” or “TBA” transactions). In a TBA transaction, a seller agrees to deliver a mortgage-backed security to the Fund at a future date, but the seller does not specify the particular security to be delivered. Instead, the Fund agrees to accept or sell any security that meets specified terms. Up to 40% of the direct investment fixed income portfolio may be comprised of below investment grade securities. The Fund may hold fixed income securities of any quality, rated or unrated, including, those that are rated below investment grade (also known as “high yield securities” or “junk bonds”) and defaulted securities. If a security is not rated by any rating agency, Guggenheim may use its discretion to determine whether that unrated security should be deemed investment grade or below investment grade for the purpose of the below investment grade limitation. If nationally or internationally recognized statistical rating organizations assign different ratings to the same security, the Fund will use the highest rating for purposes of determining the security’s credit quality. The Fund may hold securities of any duration or maturity, but generally the fixed income portfolio managed by Guggenheim will have an effective duration within 50% (whether higher or lower) of that of the Barclays U.S. Aggregate Bond Index. Guggenheim may determine to sell a security for several reasons including, but not limited to, the following:(1) to adjust the fixed income portfolio’s average maturity, or to shift assets into or out of higher-yielding securities; (2) if a security’s credit rating has been changed or for other credit reasons; (3) to meet redemption requests; (4) to take gains; or (5) due to relative value. The following describes the types of securities in which the Large Company Growth Portfolio is permitted to invest: • The Large Company Growth Portfolio focuses on the large company growth segment of the U.S. equity market. • The Large Company Growth Portfolio invests substantially all of its assets in common stock of companies with large market capitalizations—generally greater than $10 billion at the time of purchase. • The Large Company Growth Portfolio invests in companies that historically have above average earnings or sales growth and retention of earnings, often such companies have above average price to earnings ratios. • The Large Company Growth Portfolio uses a multi-manager strategy with multiple subadvisers who employ different strategies. The following describes the types of securities in which the Large Company Value Portfolio is permitted to invest: • The Large Company Value Portfolio focuses on the large company value segment of the U.S. equity market. • The Large Company Value Portfolio invests substantially all of its assets in the common stock companies with large market capitalizations—generally greater than $10 billion at the time of purchase. • The Large Company Value Portfolio invests, generally, in companies with relatively low price to book value ratios, low price to earnings ratios and higher than average dividend yields (which means that their prices are low relative to the size of their dividends). • The Large Company Value Portfolio uses a multi-manager strategy with multiple subadvisers who employ different strategies. The following describes the types of securities in which the Small Company Growth Portfolio is permitted to invest: • The Small Company Growth Portfolio focuses on the small company growth segment of the U.S. equity market. • The Small Company Growth Portfolio invests substantially all of its assets in the common stock of companies with smaller market capitalizations—which is generally less than $3 billion at the time of purchase. • The Small Company Growth Portfolio invests in companies that historically have above average earnings or sales growth and retention of earnings, often such companies have above average price to earnings ratios. • The Small Company Growth Portfolio invests in small-cap companies that may still further develop. • The Small Company Growth Portfolio uses a multi-manager strategy with multiple subadvisers who employ different strategies. The following describes the types of securities in which the Small Company Value Portfolio is permitted to invest: • The Small Company Value Portfolio focuses on the small company value segment of the U.S. equity market. • The Small Company Value Portfolio invests substantially all of its assets in the common stock of companies with smaller market capitalizations—which is generally less than $3 billion at the time of purchase. • The Small Company Value Portfolio invests, generally, in companies with relatively low price to book value ratios, low price to earnings ratios and relatively high dividend yields. • The Small Company Value Portfolio invests in small-cap companies that may still further develop. • The Small Company Value Portfolio uses a multi-manager strategy with multiple subadvisers who employ different strategies. The following describes the types of securities in which the Wilshire International Equity Fund is permitted to invest: The Wilshire International Equity Fund invests, under normal circumstances, at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities. The Wilshire International Equity Fund invests in companies organized outside the United States. Since the Wilshire International Equity Fund invests in companies of any size, it may at times invest in small-cap companies. The Wilshire International Equity Fund intends to diversify investments among several countries and to have represented in its holdings business activities in not less than three different countries. The Wilshire International Equity Fund invests primarily in equity securities of established companies that the subadvisers believe have favorable characteristics and that are listed on foreign exchanges. The Wilshire International Equity Fund may invest up to 35% of its net assets in emerging market securities, including ETFs. The Wilshire International Equity Fund may also invest in fixed-income securities of foreign governments and companies. The Wilshire International Equity Fund uses a multi-manager strategy with subadvisers who may employ different strategies. Principal Risks You may lose money by investing in the Fund.  By investing in the Fund, an investor also assumes the same types of risks, either directly, or indirectly, as investing in the Large Company Growth Portfolio, the Large Company Value Portfolio, the Small Company Growth Portfolio, the Small Company Value Portfolio and the Wilshire International Equity Fund. Investing in the Fund involves the following principal 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.    Equity Risk. The principal risk of investing in the Large Company Growth Portfolio, the Large Company Value Portfolio, the Small Company Growth Portfolio, the Small Company Value Portfolio and the Wilshire International Equity 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 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.    Credit Risk. The Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivatives contract, repurchase agreement or a loan borrower is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments, or to otherwise honor its obligations. The downgrade of the credit of a security held by the Fund may decrease its value. Securities are subject to varying degrees of credit risk, which are often, but not always, reflected in credit ratings.    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. There may be less governmental intervention in the securities markets in the near future. If so, it could cause an increase in interest rates, which would have a negative impact on fixed income securities and could negatively affect a fund’s net asset value.    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. Over the past several years, the global financial crisis has caused a significant decline in the value and liquidity of many securities and unprecedented volatility in the markets.    Governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure their debts; and many other issuers have faced difficulties obtaining credit or refinancing existing obligations. These market conditions may continue, worsen or spread, including in the United States, Europe and elsewhere. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In response to the crisis, the U.S. government and the Federal Reserve, as well as certain foreign governments and their central banks have taken steps to support financial markets, including by keeping interest rates low. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding could negatively affect financial markets generally as well as reduce the value and liquidity of certain securities.    This environment could make identifying investment risks and opportunities especially difficult for a subadviser, and whether or not a fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of a fund’s investments may be negatively affected. In addition, policy and legislative changes in the United States and in other countries are affecting many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.    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 a fund is in part dependent upon a subadviser’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 and Valuation Risk. In certain circumstances, it may be difficult for the Fund or an Underlying Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued for purposes of the Fund’s net asset value, causing the Fund to be less liquid and unable to realize what a subadviser believes should be the price of the investment.    Currency Risk. The Fund’s indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, which would cause a decline in the U.S. value of the holdings of the Fund. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political, economic and tax developments in the U.S. or abroad.    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 Securities Risk. Investing in foreign issuers may involve certain risks not typically associated with investing in securities of U.S. issuers due to increased exposure to foreign economic, political and legal developments, including favorable or unfavorable changes in currency exchange rates, foreign interest rates, exchange control regulations (including currency blockage), expropriation or nationalization of assets, imposition of withholding taxes on payments, and possible difficulty in obtaining and enforcing judgments against foreign entities. Furthermore, issuers of foreign securities and obligations are subject to different, often less comprehensive, accounting, reporting and disclosure requirements than domestic issuers. The securities and obligations of some foreign companies and foreign markets are less liquid and at times more volatile than comparable U.S. securities, obligations and markets. Securities markets in foreign countries often are not as developed, efficient or liquid as securities markets in the United States, and therefore, the prices of foreign securities can be more volatile. Certain foreign countries may impose restrictions on the ability of issuers to make payments of principal and interest to investors located outside the country. In the event of nationalization, expropriation or other confiscation, the entire investment in a foreign security could be lost. Foreign brokerage commissions and other fees are also generally higher than in the United States. There are also special tax considerations which apply to securities and obligations of foreign issuers and securities and obligations principally traded overseas. These risks may be more pronounced to the extent that the Fund or the Wilshire International Equity Fund invests a significant amount of assets in companies located in one country or geographic region, in which case the Fund may be more exposed to regional economic risks, and to the extent that the Fund or the Wilshire International Equity Fund invests in securities of issuers in emerging markets. Investments in U.S. dollar-denominated securities of foreign issuers are also subject to many of the risks described above regarding securities of foreign issuers denominated in foreign currencies.    Style Risk. The risk of investing in the Large Company Growth Portfolio, the Large Company Value Portfolio, the Small Company Growth Portfolio and the Small Company Value Portfolio is the risk that the portfolios’ growth or value styles will perform poorly or fall out of favor with investors. For example, at times the market may favor large capitalization stocks over small capitalization stocks, value stocks over growth stocks, or vice versa.    Multi-Managed Fund Risk. The Large Company Growth Portfolio, the Large Company Value Portfolio, the Small Company Growth Portfolio, the Small Company Value Portfolio and the Wilshire International Equity Fund are multi-managed funds with multiple subadvisers who employ different strategies. As a result, the Large Company Growth Portfolio, the Large Company Value Portfolio, the Small Company Growth Portfolio, the Small Company Value Portfolio and the Wilshire International Equity Fund may have buy and sell transactions in the same security on the same day.    ETF Risk. ETFs 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, involves duplication of advisory fees and certain other expenses.    Emerging Market Risk. Foreign investment risk may be particularly high to the extent the Wilshire 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.    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 than larger capitalized companies.    Market Risk. For equity securities, stock market movements may affect a 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 a 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.    Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.    Asset-Backed and Mortgage-Backed Securities Risk. Investors in asset-backed securities, including mortgage-backed securities and structured finance investments, generally receive payments that are part interest and part return of principal. These payments may vary based on the rate at which the underlying borrowers pay off their loans or other future expected receivables of assets or cash flows. Some asset-backed securities, including mortgage-backed securities, may have structures that make their reaction to interest rates and other factors difficult to predict, making them subject to liquidity risk and their prices very volatile.    Corporate Bond Risk. The market value of a corporate bond may be affected by factors directly related to the issuer, such as investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments.    Collateralized Debt Obligation (“CDO”) Risk. A CDO is an asset-backed security whose underlying collateral is typically a portfolio of bonds, bank loans, other structured finance securities and/or synthetic instruments. Where the underlying collateral is a portfolio of bonds, a CDO is referred to as a collateralized bond obligation (“CBO”). Where the underlying collateral is a portfolio of bank loans, a CDO is referred to as a collateralized loan obligation (“CLO”). Investors in CDOs bear the credit risk of the underlying collateral. Multiple tranches of securities are issued by the CDO, offering investors various maturity and credit risk characteristics. Tranches are categorized as senior, mezzanine, and subordinated/equity, according to their degree of risk. If there are defaults or the CDO’s collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. CDOs are subject to the same risk of prepayment described with respect to certain mortgage-related and asset-backed securities. The value of CDOs may be affected by changes in the market’s perception of the creditworthiness of the servicing agent for the pool or the originator.    Collateralized Mortgage Obligation (“CMO”) Risk. CMOs are debt obligations collateralized by mortgage loans or mortgage pass-through securities. The average life of a CMO is determined using mathematical models that incorporate prepayment assumptions and other factors that involve estimates of future economic and market conditions. Actual future results may vary from these estimates, particularly during periods of extreme market volatility. Further, under certain market conditions, such as those that occurred during the recent downturn in the mortgage markets, the weighted average life of certain CMOs may not accurately reflect the price volatility of such securities. For example, in periods of supply and demand imbalances in the market for such securities and/or in periods of sharp interest rate movements, the prices of CMOs may fluctuate to a greater extent than would be expected from interest rate movements alone. CMOs issued by private entities are not obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities and are not guaranteed by any government agency, although the securities underlying a CMO may be subject to a guarantee. Therefore, if the collateral securing the CMO, as well as any third party credit support or guarantees, is insufficient to make payments when due, the holder could sustain a loss. Inverse floating rate CMOs are typically more volatile than fixed or floating rate tranches of CMOs. Many inverse floating rate CMOs have coupons that move inversely to a multiple of an index. The effect of the coupon varying inversely to a multiple of an applicable index creates a leverage factor. Inverse floaters based on multiples of a stated index are designed to be highly sensitive to changes in interest rates and can subject the holders thereof to extreme reductions of yield and loss of principal. The markets for inverse floating rate CMOs with highly leveraged characteristics at times may be very thin. The Fund’s ability to dispose of its positions in such securities will depend on the degree of liquidity in the markets for such securities. It is impossible to predict the amount of trading interest that may exist in such securities, and therefore the future degree of liquidity.    Commercial Paper Risk. Commercial paper is an unsecured promissory note that generally has a maturity date between one and 270 days and is issued by a U.S. or foreign entity. Such investments are usually discounted from their value at maturity. Commercial paper can be fixed-rate or variable rate. Commercial paper can be affected by changes in interest rate and the creditworthiness of the issuer.    Convertible Securities Risk. Convertible securities may be subordinate to other securities. The total return for a convertible security depends, in part, upon the performance of the underlying security into which it can be converted. The value of convertible securities tends to decline as interest rates increase. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality.    Counterparty Credit Risk. The Fund may invest in financial instruments and OTC-traded derivatives involving counterparties for the purpose of gaining exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund will use short-term counterparty agreements to exchange the returns (or differentials in rates of return) earned or realized in particular predetermined investments or instruments. Through these investments, the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counter party. If the counterparty becomes bankrupt or defaults on its payment obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive. If this occurs, the value of your shares in the Fund will decrease. The Fund bears the risk that counterparties may be adversely affected by legislative or regulatory changes, adverse market conditions, increased competition, and/or wide scale credit losses resulting from financial difficulties or borrowers affecting counterparties.    Credit-Linked Note Risk. Credit-linked notes are a type of structured note. Through the purchase of a credit-linked note, the buyer assumes the risk of the reference asset and funds this exposure through the purchase of the note. Credit-linked notes are subject to the credit risk of the corporate credits referenced by the note. The Fund bears the risk that the issuer of the credit-linked note will default or become bankrupt. The Fund bears the risk of loss of its principal investment, and the periodic interest payments expected to be received for the duration of its investment in the credit-linked note.    Extension Risk. Mortgage-related and other asset-backed securities are subject to Extension Risk, which is the risk that the issuer of such a security pays back the principal of such an obligation later than expected. This may occur when interest rates rise. This may negatively affect Fund returns, as the value of the security decreases when principal payments are made later than expected. In addition, because principal payments are made later than expected, the Fund may be prevented from investing proceeds it would otherwise have received at a given time at the higher prevailing interest rates.    High Yield and Unrated Securities Risk. High yield, below investment grade and unrated high risk debt securities may present additional risk because these securities may be less liquid and present more credit risk than investment grade bonds. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.    Investment in Investment Vehicles Risk. Investing in other investment vehicles, including exchange-traded funds (“ETFs”), closed-end funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease. Moreover, the Fund will incur its pro rata share of the underlying vehicles’ expenses.    Investments in Loans Risk. Investments in loans involve special types of risks, including credit risk, interest rate risk, counterparty risk and prepayment risk. Loans may offer a fixed or floating interest rate. Loans are often generally below investment grade and may be unrated. Loans may be difficult to value and some can be subject to liquidity risk.    Leverage Risk. The Fund’s use of leverage, through borrowings or instruments such as derivatives, repurchase agreements, or reverse repurchase agreements, may cause the Fund to be more volatile and riskier than if it had not been leveraged.    Management Risk. The Fund is subject to Management risk, the risk that the investment techniques and risk analyses applied by Guggenheim will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to Guggenheim and the individual portfolio manager in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved. Furthermore, active trading that can accompany active management will increase the costs the Fund incurs because of higher brokerage charges or mark-up charges, which are passed on to shareholders of the Fund and, as a result, may lower the Fund’s performance.    Mezzanine Investments Risk. The Fund may invest in certain lower grade securities known as “Mezzanine Investments,” which are subordinated debt securities that are generally issued in private placements in connection with an equity security (e.g., with attached warrants) or may be convertible into equity securities. Mezzanine Investments are generally subject to similar risks associated with investment in senior loans, second lien loans and other below investment grade securities. However, Mezzanine Investments may rank lower in right of payment than any outstanding senior loans, second lien loans and other debt instruments with higher priority of the borrower, or may be unsecured (i.e., not backed by a security interest in any specific collateral), and are subject to the additional risk that the cash flow of the borrower and available assets may be insufficient to meet scheduled payments and repayment of principal after giving effect to any higher ranking obligations of the borrower. Mezzanine Investments are expected to have greater price volatility and exposure to losses upon default than senior loans and second lien loans and may be less liquid.    Municipal Securities Risk. Municipal securities may be subject to credit, interest and prepayment risks. In addition, municipal securities can be affected by unfavorable legislative or political developments and adverse changes in the economic and fiscal conditions of state and municipal issuers or the federal government in case it provides financial support to such issuers. Certain sectors of the municipal bond market have special risks that can affect them more significantly than the market as a whole. Because many municipal instruments are issued to finance similar projects, conditions in these industries can significantly affect the overall municipal market. Municipal securities that are insured by an insurer may be adversely affected by developments relevant to that particular insurer, or more general developments relevant to the market as a whole. Municipal securities can be difficult to value and be less liquid than other investments, which may affect performance.    Privately Issued Securities Risk. The Fund may invest in privately-issued securities of public and private companies. Privately issued securities have additional risk considerations than investments in comparable public investments. Whenever the Fund invests in companies that do not publicly report financial and other material information, it assumes a greater degree of investment risk and reliance upon Guggenheim’s ability to obtain and evaluate applicable information concerning such companies’ creditworthiness and other investment considerations. Certain privately-issued securities may be illiquid. If there is no readily available trading market for privately-issued securities, the Fund may not be able to readily dispose of such investments at prices that approximate those at which the Fund could sell them if they were more widely traded. Privately-issued securities are also more difficult to value. Privately-issued debt securities are often of below investment grade quality, frequently are unrated and present many of the same risks as investing in below investment grade public debt securities.    Prepayment Risk. The issuers of securities held by the Fund may be able to prepay principal due on the securities, particularly during periods of declining interest rates. Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, and may offer a greater potential for loss when interest rates rise. In addition, rising interest rates may cause prepayments to occur at a slower than expected rate, thereby effectively lengthening the maturity of the security and making the security more sensitive to interest rate changes. Prepayment risk is a major risk of mortgage-backed securities and certain asset-backed securities. Most floating rate loans (such as syndicated bank loans) and debt securities allow for prepayment of principal without penalty. Accordingly, the potential for the value of a floating rate loan or security to increase in response to interest rate declines is limited. Corporate loans or securities purchased to replace a prepaid corporate loan or security may have lower yields than the yield on the prepaid corporate loan.    Preferred Securities Risk. A company’s preferred stock generally pays dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects.    Regulatory and Legal Risk. U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund (such as regulations related to investments in derivatives). These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.    Repurchase Agreement and Reverse Repurchase Agreement Risk. In the event of the insolvency of the counterparty to a repurchase agreement or reverse repurchase agreement, recovery of the repurchase price owed to the Fund or, in the case of a reverse repurchase agreement, the securities sold by the Fund, may be delayed. Because reverse repurchase agreements may be considered to be the practical equivalent of borrowing funds, they constitute a form of leverage. If the Fund reinvests the proceeds of a reverse repurchase agreement at a rate lower than the cost of the agreement, entering into the agreement will lower the Fund’s yield.    Restricted Securities Risk. Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.    Structured Notes Risk. Investments in structured notes involve risks associated with the issuer of the note and the reference instrument. Where the Fund’s investments in structured notes are based upon the movement of one or more factors used as a reference for payments required on the note, including currency exchange rates, interest rates, referenced bonds or stock indices, depending on the use of multipliers or deflators, changes in the applicable factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured note to be reduced to zero, and any further changes in the reference instrument may then reduce the principal amount payable on maturity. Structured notes may be less liquid than other types of securities and more volatile than the reference instrument or security underlying the note.    Synthetic Investment Risk. The Fund may be exposed to certain additional risks should Guggenheim use derivatives transactions as a means to synthetically implement the Fund’s investment strategies. Customized derivative instruments will likely be highly illiquid, and it is possible that the Fund will not be able to terminate such derivative instruments prior to their expiration date or that the penalties associated with such a termination might impact the Fund’s performance in a materially adverse manner. Synthetic investments may be imperfectly correlated to the investment Guggenheim is seeking to replicate.    To Be Announced (“TBA”) Transactions Risk. The Fund may enter into “To Be Announced” (“TBA”) transactions to purchase or sell mortgage-backed securities for a fixed price at a future date. TBA purchase commitments involve a risk of loss if the value of the securities to be purchased declines prior to settlement date or if the counterparty may not deliver the securities as promised. Selling a TBA involves a risk of loss if the value of the securities to be sold goes up prior to settlement date.    When Issued and Forward Commitment Risk. When-issued, forward-commitment and delayed-delivery transactions involve a commitment to purchase or sell specific securities at a predetermined price or yield in which payment and delivery take place after the customary settlement period for that type of security. When purchasing securities pursuant to one of these transactions, payment for the securities is not required until the delivery date. However, the purchaser assumes the rights and risks of ownership, including the risks of price and yield fluctuations and the risk that the security will not be issued as anticipated.  Performance The information below provides an illustration of how the Fund’s performance has varied over time. The bar chart and table provide some indication of the risks of investing in the Fund by showing the changes in the Fund’s investment performance from year to year during the periods indicated and by showing how the average annual total returns for the one-, five- and ten-year periods compare with a broad-based securities market index and additional indexes with characteristics relevant to the Fund. The total return figures do not reflect expenses that apply to the separate account or related annuity contracts. The inclusion of these charges would reduce the total return figures for all periods shown.
