EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although the actual costs may be higher or lower, based on these assumptions your cost would be:

Class A	553	776	1,016	1,706
Class C	258	571	1,011	2,233
Institutional Class	56	243	446	1,032

Not Redeemed

Expense Example, No Redemption MUNICIPAL INCOME FUND (USD $)	1 Year	3 Years	5 Years	10 Years

Institutional Class	56	243	446	1,032

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 121% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

In pursuit of its objective, the Fund will invest, under normal market conditions, at least 80% of its assets (net assets, plus the amount of any borrowing for investment purposes) in a diversified portfolio of municipal securities whose interest is free from federal income tax. This investment strategy 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, 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, options, structured securities, inverse floating rate instruments, swaps, caps, floors, and collars. 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 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.

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 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 (“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, the Fund’s sub-adviser, uses a process for selecting securities for purchase and sale that is based on intensive credit research and involves extensive due diligence on each issuer, region and sector. Guggenheim Partners also considers macroeconomic outlook and geopolitical issues.

Guggenheim Partners may determine to sell a security: (1) to adjust the 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 (3) to meet redemption requests, among other reasons. Under adverse market conditions (for example, in the event of credit events, where it is deemed opportune to preserve gains, or to preserve the relative value of investments), the Fund can make temporary defensive investments and may not be able to pursue its objective.

PRINCIPAL RISKS

The value of an investment in the Fund will fluctuate and is subject to investment risks, which means investors could lose money. The principal risks of investing in the Fund are listed below.

Asset-Backed and Mortgage-Backed Securities Risk – Investors in asset-backed securities, including mortgage-backed securities, 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, making their prices very volatile and they are subject to liquidity risk.

Credit Risk – The Fund could lose money if the issuer of a bond or a counterparty to a derivatives transaction or repurchase agreement is unable to repay interest and principal on time or defaults. The issuer of a bond could also suffer a decrease in quality rating, which would affect the volatility of the price and liquidity of the bond.

Derivatives Risk – Derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including possible illiquidity of the derivative, limited ability to enter into or unwind a position, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, leverage risk, lack of availability and the risk that the counterparty may default on its obligations. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could result in a loss, which in some cases may be unlimited.

Emerging Markets Risk – Investments in emerging markets securities are generally subject to a greater level of those risks associated with investing in foreign securities, as emerging markets are considered less developed and developing countries.

Foreign Securities Risk – Foreign securities carry additional risks when compared to U.S. securities, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

High Yield and Unrated Securities Risk – Higher yielding, 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.

Interest Rate Risk – Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Investment in Investment Vehicles Risk – Investing in other investment vehicles, including closed-end funds, ETFs, 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 and its shareholders 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, may cause the Fund to be more volatile than if it had not been leveraged.

Liquidity and Valuation Risk – In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Manager for purposes of 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.

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 be successful. Furthermore, active trading that can accompany active management, also called “high turnover,” may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund.

Market Risk – The market value of the securities held by the Fund may fluctuate as a result of factors affecting individual companies or other factors such as changing economic, political or financial market conditions. Moreover, changing economic, political or financial market conditions in one country or geographic region could adversely impact the market value of the securities held by the Fund in a different country or geographic region.

Municipal Securities Risk – Municipal securities can be affected by unfavorable legislative or political developments and adverse changes in the financial conditions of state and municipal issuers or the federal government in case it provides financial support to the municipality. 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.

Prepayment Risk – Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities, and may offer a greater potential for income loss when interest rates rise.

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 and financial risk, which may result in substantial losses to the Fund.

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.

PERFORMANCE INFORMATION

The following chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s Class A share performance from year to year and by showing how the Fund’s average annual returns for the one year, five years and since inception periods have 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 1-800-820-0888.

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. The bar chart also does not reflect the impact of the sales charge applicable to Class A shares which, if reflected, would lower the returns shown.

AVERAGE ANNUAL TOTAL RETURNS

(For the periods ended December 31, 2012)

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.

No information is shown for Class C and Institutional Class shares because these shares do not have a full year of calendar performance. Performance information for these shares will appear in a future version of the prospectus once there is a full calendar year of performance information to report.

[1] Expense information has been restated to reflect current fees.

[2] The Investment Manager has contractually agreed through February 1, 2014 to waive fees and or reimburse Fund expenses to the extent necessary to limit the ordinary operating expenses (including distribution (12b1) fees, but exclusive of brokerage costs, dividends on securities sold short, acquired fund fees and expenses, interest, taxes, litigation, indemnification, and extraordinary expenses) ('Operating Expenses') of the Fund to an annual percentage of average daily net assets for each class of shares as follows: Class A 0.80%; Class C 1.55%; and Institutional Class 0.55%. The Fund may have 'Total annual fund operating expenses after fee waiver' greater than the expense cap as a result of any acquired fund fees and expenses or other expenses that are excluded from the calculation. The Investment Manager is entitled to reimbursement by the Fund of fees waived or expenses reimbursed during any of the previous 36 months beginning on the date of the expense limitation agreement. The agreement will expire, if it is not renewed, when it reaches its termination (subject to recoupment rights) or when Security Investors ceases to serve as the investment manager.
