This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may be required to pay a commission to your financial intermediary for effecting transactions in a class of shares of the Fund without any initial sales charge, contingent deferred sales charge, or other asset-based fee for sales or distribution. These commissions are not reflected in the fee and expense table or expense example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Family of Funds, as defined on page 150 of the Fund’s prospectus. This amount may vary depending on the Guggenheim Fund in which you invest. More information about these and other discounts is available from your financial professional and in the “Sales Charges-Class A Shares” section on page 101 of the Fund’s prospectus and the “How to Purchase Shares” section on page 80 of the Fund’s Statement of Additional Information. Different intermediaries and financial professionals may impose different sales charges or offer different sales charge waivers or discounts. These variations are described in Appendix A to the Fund’s prospectus (Intermediary-Specific Sales Charge Waivers and Discounts).

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio.

In pursuit of its objective, the Fund will invest, under normal circumstances, at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in a diversified portfolio of municipal securities whose interest is free from federal income tax. This investment policy may not be changed without shareholder approval. Interest from the Fund’s investments may be subject to the federal alternative minimum tax. The Fund may invest up to 20% of its assets in securities the interest on which is subject to federal income taxation, including, among others, corporate bonds and other corporate debt securities, taxable municipal securities (which include Build America Bonds and Qualified School Construction Bonds), mortgage-backed and asset backed securities (including collateralized debt obligations), repurchase and reverse repurchase agreements, syndicated bank loans and securities issued by the U.S. government or its agencies and instrumentalities (including those not backed by the full faith and credit of the U.S. government). The Fund also may invest up to 20% of its assets in a variety of investment vehicles, principally closed-end funds, exchange-traded funds (“ETFs”) and other mutual funds. The Fund may use derivatives for investment purposes (i.e., speculative purposes). Derivatives include futures, forward contracts, Eurodollar futures, options, structured securities, inverse floating rate instruments, swaps, caps, floors, and collars (some of these instruments may be traded in the over-the-counter market). When market conditions are deemed appropriate, the Fund will use leverage to the full extent permitted by its investment policies and restrictions and applicable law. The Fund may use leverage by using derivatives and municipal tender option bonds (“TOBs”), or by entering into reverse repurchase agreements and borrowing transactions (principally lines of credit) for investment purposes. The fixed-income securities in which the Fund invests will primarily be domestic securities, but may also include, up to 20% of its assets, in foreign and emerging markets securities (such as sovereign debt securities and Eurodollar bonds and obligations).

The Fund will allocate assets across different market sectors and maturities and may invest in municipal bonds rated in any rating category or in unrated municipal bonds. The Fund, however, will invest under normal market conditions, at least 80% of its net assets in investment grade securities (i.e., rated in the top four long-term rating categories by a nationally recognized statistical ratings organization or, if unrated, determined by Guggenheim Partners Investment Management, LLC, also known as Guggenheim Investments (“Guggenheim Partners” or the “Sub-Adviser”) to be of comparable quality). If nationally recognized statistical rating organizations assign different ratings to the same security, the Fund will use the higher rating for purposes of determining the security’s credit quality. The Fund may invest 25% or more of the Fund’s assets in municipal instruments that finance similar projects, such as those relating to education, healthcare, housing, utilities, or water and sewers.

Guggenheim Partners may determine to sell an instrument for several reasons, including but not limited to the following: (1) to adjust the portfolio’s average maturity or duration, or to shift assets into or out of higher-yielding securities; (2) if a security’s credit rating has been changed, our credit outlook has changed, or for other similar reasons; (3) to meet redemption requests; (4) to take gains; or (5) due to relative value. Under adverse or unstable market conditions or abnormal circumstances (for example, in the event of credit events, where it is deemed opportune to preserve gains, or to preserve the relative value of investments or in the case of large cash inflows or anticipated

Asset-Backed Securities Risk—Investors in asset-backed securities, including residential mortgage-backed securities, commercial mortgage-backed securities and other 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. Some asset-backed securities, including mortgage-backed securities, may have structures that make their reaction to interest rates and other factors difficult to predict, causing their prices to be volatile. These instruments are particularly subject to interest rate, credit and liquidity and valuation risks.

Collateralized Loan Obligations and Collateralized Debt Obligations Risk—Collateralized loan obligations (“CLOs”) bear many of the same risks as other forms of asset-backed securities, including interest rate risk, credit risk and default risk. As they are backed by pools of loans, CLOs also bear similar risks to investing in loans directly. CLOs issue classes or “tranches” that vary in risk and yield. CLOs may experience substantial losses attributable to loan defaults. Losses caused by defaults on underlying assets are borne first by the holders of subordinate tranches. The Fund’s investment in CLOs may decrease in market value when the CLO experiences loan defaults or credit impairment, the disappearance of a subordinate tranche, or market anticipation of defaults and investor aversion to CLO securities as a class.

Collateralized debt obligations (“CDOs”) are structured similarly to CLOs and bear the same risks as CLOs including interest rate risk, credit risk and default risk. CDOs are subject to additional risks because they are backed by pools of assets other than loans including securities (such as other asset-backed securities), synthetic instruments or bonds and may be highly leveraged. Like CLOs, losses incurred by a CDO are borne first by holders of subordinate tranches. Accordingly, the risks of CDOs depend largely on the type of underlying collateral and the tranche of CDOs in which the Fund invests. For example, CDOs that obtain their exposure through synthetic investments entail the risks associated with derivative instruments.

Counterparty Credit Risk—The Fund makes investments in financial instruments and over-the-counter ("OTC")-traded derivatives involving counterparties to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements (e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a derivatives transaction or other transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Derivatives Risk—Derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund’s use of derivatives may cause the Fund to realize higher amounts of short term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened credit, liquidity and valuation risks.

Extension Risk—Certain debt instruments, including mortgage- and other asset-backed securities, are subject to the risk that payments on principal may occur at a slower rate or later than expected. In this event, the expected maturity could lengthen and the Fund’s investment may sharply decrease in value and the Fund’s income from the investment may quickly decline. These types of instruments are particularly subject to extension risk, and offer less potential for gains, during periods of rising interest rates. In addition, the Fund may be delayed in its ability to reinvest income or proceeds from these instruments in potentially higher yielding investments, which would adversely affect the Fund.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, 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. This exposure may be obtained through investments in other investment companies.

Interest Rate Risk—Investments in fixed-income instruments and other debt instruments are subject to the possibility that interest rates could rise sharply, which may cause the value of the Fund’s holdings and share price to decline. Changes in interest rates may also affect the liquidity of the Fund's investments in fixed-income instruments. The risks associated with rising interest rates are heightened given the recent near historically low interest rate environment and, as of the date of this prospectus, increasing interest rate environment. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations. During periods of rising interest rates, because changes in interest rates on adjustable rate securities may lag behind changes in market rates, the value of such securities may decline until their interest rates reset to market rates. During periods of declining interest rates, because the interest rates on adjustable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities.

Investment in Investment Vehicles Risk—Investing in other investment vehicles, including 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 or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund’s performance. In addition, investments in an ETF are subject to, among other risks, the risk that the ETF's shares may trade at a discount or premium relative to the net asset value of the shares and the listing exchange may halt trading of the ETF's shares.

Investment in Loans Risk—The Fund may invest in loans through assignments, participations or directly. Investments in loans, including loan syndicates and other direct lending opportunities, 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. The Fund’s investments in loans can also be difficult to value accurately and may be more susceptible to liquidity risk than fixed-income instruments of similar credit quality and/or maturity. The Fund is also subject to the risk that the value of any collateral for the loan may be insufficient or unavailable to cover the borrower’s obligations should the borrower fail to make payments, become insolvent, or otherwise default. Participations in loans may subject the Fund to the credit risk of both the borrower and the issuer of the participation and may make enforcement of loan covenants, if any, more difficult for the Fund as legal action may have to go through the issuer of the participation (or an agent acting on its behalf). Transactions in loans are often subject to long settlement periods, thus potentially limiting the ability of the Fund to invest sale proceeds in other investments and to use proceeds to meet its current redemption obligations.

the Fund’s net asset value, causing the Fund to be less liquid and unable to realize what the Investment Manager believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the near historically low interest rate environment as of the date of this prospectus. Based on its investment strategies, a significant portion of the Fund's investments can be difficult to value and potentially less liquid and thus particularly prone to the foregoing risks.

Management Risk—The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, causing the Fund to fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active and frequent trading that can accompany active management, also called “high turnover,” may have a negative impact on performance. Active and frequent trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active and frequent trading may also result in adverse tax consequences.

Municipal Securities Risk—Municipal securities are subject to a variety of risks, including credit, interest, prepayment, liquidity, and valuation risks. In addition, municipal securities can be adversely affected by (i) unfavorable legislative, political or other developments or events, including natural disasters, and (ii) 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. To the extent a Fund invests a substantial portion of its assets in securities issued by a particular state or municipality, the Fund will be particularly sensitive to developments and events adversely affecting such issuer. 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 or the ability to meet fund redemption requests.

Prepayment Risk—Certain debt instruments, including loans and mortgage- and other asset-backed securities, are subject to the risk that payments on principal may occur more quickly or earlier than expected. In this event, the Fund might be forced to forego future interest income on the principal repaid early and to reinvest income or proceeds at generally lower interest rates, thus reducing the Fund’s yield. These types of instruments are particularly subject to prepayment risk, and offer less potential for gains, during periods of declining interest rates.

Regulatory and Legal Risk—U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators 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 and other transactions). These regulations and laws impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Repurchase Agreements and Reverse Repurchase Agreements 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.

Sovereign Debt Risk—The debt securities issued by sovereign entities may decline as a result of default or other adverse credit event resulting from a sovereign debtor's unwillingness or inability to repay principal and pay interest in a timely manner, which may be affected by a variety of factors, including its cash flow situation, the extent of its reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt

Tender Option Bonds Risk—Tender option bonds, residual interest tender option bonds and inverse floaters expose the Fund to the same risks as investments in derivatives, as well as risks associated with leverage, especially the risk of increased volatility. An investment in these securities typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Because distributions on these securities will bear an inverse relationship to short-term municipal security interest rates, distributions will be reduced or, in the extreme, eliminated as rates rise and will increase when rates fall.

The following chart and table provide some indication of the risks of investing in the Fund by showing the Fund’s Class A share calendar year performance from year to year and average annual returns for the one, five and ten year or since inception periods (if shorter), as applicable, for the Fund’s Class A, Class C, Institutional Class, and Class P shares compared to those of a broad measure of market performance. As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available on the Fund’s website at www.guggenheiminvestments.com or by calling 800.820.0888.

On January 13, 2012, the Fund acquired the assets and assumed the liabilities of TS&W/Claymore Tax-Advantaged Balanced Fund (the “Predecessor Fund”), a closed-end fund which used different investment strategies and had different investment advisers (the “Reorganization”). Class A shares of the Fund have assumed the performance, financial and other historical information of the Predecessor Fund’s Common Shares. Returns are based on the net asset value of fund shares. The performance of Class A shares of the Fund reflects the performance of the Predecessor Fund. Performance has not been restated to reflect the estimated annual operating expenses of Class A shares.

After-tax returns shown in the table are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local taxes. Actual after-tax returns depend on an investor’s 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 (“IRAs”). After-tax returns are shown for Class A only. After-tax returns for Class C, Institutional Class, and Class P will vary. The returns shown below reflect applicable sales charges, if any.

You may purchase or redeem Fund shares through your broker/dealer, other financial intermediary that has an agreement with Guggenheim Funds Distributors, LLC, the Fund’s distributor, or, for shares of each class other than Class P shares, through the Fund’s transfer agent. You may purchase, redeem or exchange shares of any class of the Fund on any day the New York Stock Exchange is open for business. The minimum initial investment for Class A and Class C shares is $2,500. The minimum subsequent investment is $100. Class A and Class C do not have a minimum account balance.

The Institutional Class minimum initial investment is $2 million, although the Investment Manager may waive this requirement at its discretion. The Institutional Class has a minimum account balance of $1 million. Due to the relatively high cost of maintaining accounts below the minimum account balance, the Fund reserves the right to redeem shares if an account balance falls below the minimum account balance for any reason. Investors will be given 60 days notice to reestablish the minimum account balance. If the account balance is not increased, the account may be closed and the proceeds sent to the investor. Institutional Class shares of the Fund will be redeemed at net asset value on the day the account is closed.

Class P shares of the Fund are offered through broker/dealers and other financial intermediaries with which Guggenheim Funds Distributors, LLC has an agreement for the use of Class P shares of the Fund in investment products, programs or accounts. Class P shares do not have a minimum initial investment amount, subsequent investment amount or a minimum account balance. The Fund reserves the right to modify its minimum investment amount and account balance requirements at any time, with or without prior notice to you.

If you purchase Fund shares through a broker/dealer or other financial intermediary, the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker/dealer or other intermediary and your sales person to recommend the Fund over another investment. Ask your sales person or visit your financial intermediary’s website for more information.
