Shareholder Expense Example (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase or redemption payments; and (2) ongoing costs, including management fees and to the extent applicable, distribution (12b-1) fees and/or shareholder services fees and other Fund expenses. This Example is intended to help you to understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. It is based on an investment of $1,000 invested at the beginning of the period and held for the entire period from October 1, 2009 to March 31, 2010.

ACTUAL EXPENSES

The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you incurred over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses attributable to your investment during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. Thus, you should not use the hypothetical account values and expenses to estimate the actual ending account balance or your expenses for the period. Rather, these figures are required to be provided to enable you to compare the ongoing costs of investing in the Fund with other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) on purchase or redemption payments. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

	Beginning Account Value 10/1/2009	Ending Account Value 3/31/2010	Expenses Paid During Period1
Actual:
Class A Shares	$1,000	$997.40	$4.33
Class B Shares	$1,000	$993.00	$8.50
Class C Shares	$1,000	$993.00	$8.50
Class F Shares	$1,000	$997.40	$4.33
Hypothetical (assuming a 5% return before expenses):
Class A Shares	$1,000	$1,020.59	$4.38
Class B Shares	$1,000	$1,016.40	$8.60
Class C Shares	$1,000	$1,016.40	$8.60
Class F Shares	$1,000	$1,020.59	$4.38

1 Expenses are equal to the Fund's annualized net expense ratios, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half-year period). The annualized net expense ratios are as follows:

Class A Shares	0.87%
Class B Shares	1.71%
Class C Shares	1.71%
Class F Shares	0.87%

Management's Discussion of Fund Performance (unaudited)

The Fund's total return, based on net asset value (NAV), for the 12-month reporting period ended March 31, 2010, was 10.78% for the Fund's Class A Shares and Class F Shares and 9.81% for the Fund's Class B Shares and Class C Shares. The total return of the Barclays Capital Municipal Bond Index (BCMB),¹ the Fund's benchmark index, was 9.69% during the same period. The Fund's total return for the most recently completed fiscal year reflected actual cash flows, transaction costs and other expenses, which were not reflected in the total return of the BCMB.

The Fund's investment strategy focused on: (a) the effective duration of its portfolio (which indicates the portfolio's sensitivity to changes in interest rates);²(b) the allocation of the portfolio among securities of similar issuers (referred to as sectors); and (c) the credit rating of portfolio securities. These were the most significant factors affecting the Fund's performance relative to the BCMB.

1

The BCMB is an unmanaged, market value-weighted index for the long-term, tax-exempt bond market. To be included in the BCMB, bonds must have a minimum credit rating of Baa3/BBB-, an outstanding par value of at least $7 million and be issued as part of a transaction of at least $75 million. The bonds must be fixed rate, have an issue date after December 31, 1990, and must be at least one year from their maturity date. Remarketed issues, taxable municipal bonds, bonds with floating rates and derivatives are excluded from the BCMB. The BCMB is not adjusted to reflect sales charges, expenses and other fees that the Securities and Exchange Commission (SEC) requires to be reflected in the Fund's performance. The BCMB is unmanaged and unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index.

2

Bond prices are sensitive to changes in interest rates and a rise in interest rates can cause a decline in their prices.

Annual Shareholder Report

7

The following discussion will focus on the performance of the Fund's Class A Shares. The 10.78% total return for the Class A Shares for the reporting period consisted of 4.62% of tax-exempt dividends and reinvestments, and 6.16% appreciation in the net asset value of the shares.³

Market Overview

During the reporting period, economic growth strengthened, firms reduced payrolls at a less rapid pace and downside risks to economic growth diminished. The housing sector showed signs of improvement, though housing starts leveled out and building activity remained low. Several factors continued to restrain the expansion in economic activity. The commercial real estate market continued to deteriorate, bank credit contracted further and a concern remained about the economy's ability to generate a self sustaining recovery without significant government support. However, financial market conditions showed signs of stabilizing as equity prices rose, credit spreads narrowed and markets in general functioned significantly better during the Fund's most recent fiscal year than in 2008 and early 2009. Substantial resource slack continued to restrain longer term inflation expectations. The Federal Reserve maintained the federal funds rate in a range from 0.00% to 0.25% during the entire reporting period.

3 Income may be subject to state and local taxes. The investment adviser normally (except as disclosed in the Fund's Prospectus) will invest the Fund's assets entirely in securities whose interest is not subject to the alternative minimum tax for individuals and corporations (AMT), such that, normally, distributions of annual interest income are exempt from the AMT (in addition to the federal regular income tax). However, in certain circumstances (such as, for example, when there is a lack of supply of non-AMT securities or there are advantageous market conditions, or there is a change in law relating to the AMT), to pursue the Fund's investment objective, the Fund's adviser may invest the Fund's assets in securities that may be subject to the AMT. When there is a lack of supply of non-AMT securities and/or other circumstances that exist, such circumstances may result in the fund acquiring AMT securities that are consistent with the Fund's investment objective. These acquisitions may occur in the ordinary course or in connection with fund reorganization transactions (i.e., transactions in which the Fund acquires the portfolio securities of other mutual funds), an issuer bankruptcy or another event or circumstance. In such circumstances, interest from the Fund's investments may be subject to the AMT.

The combined fiscal and monetary stimuli drove an impressive rebound in the valuation of risky assets. In the tax-exempt municipal market, 10-year ratios of AAA-rated municipal yields to 10-year Treasury yields declined from a record peak of 146% in April 2009, to a trough of 76% in September of 2009. Municipal credit spreads also declined significantly as the spread between 10-year A-rated and AAA-rated municipal bonds declined by 90 basis points over the same period. This extensive normalization of the tax-exempt municipal market from the market disruptions in 2008 appeared to result from several positive technical factors. Significant federal financial support programs for state governments were put in place to stimulate local economies and boost confidence. The Build America Bonds program reduced the supply of tax-exempt municipal bonds issued, helping to create a shortage of tax-exempt bonds available in the market. Ongoing strong demand for yield from investors as money market rates remained very low, the expectations of higher marginal tax rates and strong mutual fund flows led to solid demand for tax-exempt debt. These factors helped to create the supply and demand imbalance that has enabled the municipal market to recover and provide positive returns over the past year.

Duration⁴

As determined at the end of the reporting period, the Fund's dollar-weighted average duration for the reporting period was 7.48 years. Duration management continued to be a significant component of the Fund's investment strategy. The shorter a fund's duration relative to an index, the less its net asset value will react as interest rates change. The Fund adjusted duration relative to the BCMB several times during the reporting period. Tax-exempt municipal bond yields declined significantly as the market stabilized and then recovered from a near-crisis environment to one of improved liquidity, a near-zero Federal funds rate and increased investment activity. As a result of the Fund's allocation to bonds with shorter durations than those of the BCMB, duration was a negative contributor to Fund performance.

4 Duration is a measure of a security's price sensitivity to changes in interest rates. Securities with longer durations are more sensitive to changes in interest rates than securities with shorter durations. For purposes of this Management's Discussion of Fund Performance, duration is determined using a third-party analytical system.

Sector

Over the course of the past year, the Fund maintained a higher portfolio allocation to securities issued by hospitals, water and sewer projects and single family housing bonds. These allocations helped the Fund's performance due to the narrowing of credit spreads within the essential service revenue bond sectors. The Fund increased its exposure to highly rated general obligation bonds issued by states and school districts and this allocation to higher quality municipal debt had a positive performance impact over the period. The Fund also allocated a portion of the portfolio to pre-refunded, tax-exempt municipal bonds (bonds for which the principal and interest payments are secured or guaranteed by cash or U.S. Treasury securities held in an escrow account). The exposure to pre-refunded bonds had a negative impact on performance due to lower price volatility exhibited by pre-refunded bonds as compared to other sectors. The Fund was also underweight Tobacco Settlement bonds and had no exposure to noninvestment-grade debt, which had a negative performance impact due to the rally in the riskier asset sectors.

Credit Quality⁵

Risk-aversion by investors subsided as the financial markets stabilized and a preference for yield resulted in the outperformance of bonds rated A and BBB relative to bonds rated in the higher rating categories. With the decrease in credit spreads over the period, and the narrowing of credit spreads to a greater extent for A and BBB-rated (or comparable quality) debt, the Fund's overweight, relative to the BCMB, in BBB-rated debt during the 12-month reporting period helped the Fund's performance, as the yield on BBB-rated debt decreased to a greater extent than for other investment-grade securities.⁶

5

Credit ratings pertain only to the securities in the portfolio and do not protect fund shares against market risk.

6

Investment-grade securities are securities that are rated at least BBB or unrated securities of a comparable quality. Noninvestment-grade securities are securities that are not rated at least BBB or unrated securities of a comparable quality. Credit ratings are an indication of the risk that a security will default. They do not protect a security from credit risk. Lower-rated bonds typically offer higher yields to help compensate investors for the increased risk associated with them. Among these risks are lower creditworthiness, greater price volatility, more risk to principal and income than with higher-rated securities and increased possibilities of default.

Performance data quoted represents past performance which is no guarantee of future results. Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Mutual fund performance changes over time and current performance may be lower or higher than what is stated. For current to the most recent month-end performance and after-tax returns, visit FederatedInvestors.com or call 1-800-341-7400. Returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Mutual funds are not obligations of or guaranteed by any bank and are not federally insured. Total returns shown include the maximum contingent deferred sales charge of 1.00% as applicable.

1	Represents a hypothetical investment of $10,000 in the Fund. A 1.00% contingent deferred sales charge would be applied to any redemption less than one year from the purchase date. The Fund's performance assumes the reinvestment of all dividends and distributions. The BCMB and the LGMFA have been adjusted to reflect reinvestment of dividends on securities in the index and average.
2	The BCMB is an unmanaged market value-weighted index for the long-term, tax-exempt bond market. To be included in the BCMB, bonds must have a minimum credit rating of Baa3/BBB-, an outstanding par value of at least $7 million and be issued as part of a transaction of at least $75 million. The bonds must be fixed rate, have an issue date after December 31, 1990 and must be at least one year from their maturity date. Remarketed issues, taxable municipal bonds, bonds with floating rates and derivatives are excluded from the index. The BCMB is not adjusted to reflect sales charges, expenses and other fees that the SEC requires to be reflected in the Fund's performance. The BCMB is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index.
3	The LGMFA represents the average of the total returns reported by all of the mutual funds designated by Lipper, Inc. as falling in the respective category indicated, and is not adjusted to reflect any sales charges. However, these total returns are reported net of expenses or other fees that the SEC requires to be reflected in a fund's performance.
4	Total returns quoted reflect all applicable contingent deferred sales charges.

Level 1 — quoted prices in active markets for identical securities

Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

Level 3 — significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities.

Notes to Financial Statements

March 31, 2010

1. Organization

Federated Municipal Securities Fund, Inc. (the “Fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company. The Fund offers four classes of shares: Class A Shares, Class B Shares, Class C Shares and Class F Shares. All shares of the Fund have equal rights with respect to voting, except on class-specific matters. The investment objective of the Fund is to provide for its shareholders a high level of current income which is exempt from federal regular income tax. Interest income from the Fund's investments normally will not be subject to federal AMT for individuals and corporations, but may be subject to state and local taxes.

On December 6, 2009, the Fund acquired all of the net assets of Federated California Municipal Income Fund and Federated North Carolina Municipal Income Fund (the “Acquired Funds”), open-end investment companies in a tax-free reorganization in exchange for shares of the Fund, pursuant to a plan of reorganization approved by the Acquired Funds' shareholders on November 20, 2009. The primary purposes of the transaction were to provide the shareholders of the Acquired Funds a competitive, more diversified and more viable fund with share class expense ratios ultimately lower than what the expense ratios of the Acquired Funds would have been after the Adviser and its affiliates eliminated or substantially reduced the voluntary waivers on the Acquired Funds' share classes. For financial reporting purposes, assets received and shares issued by the Fund were recorded at fair value; however, the cost basis of the investments received from the Acquired Funds was carried forward to align ongoing reporting of the Fund's realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

Assuming the acquisition had been completed on April 1, 2009, the beginning of the annual reporting period of the Fund, the Fund's pro forma results of operations for the year ended March 31, 2010, are as follows:

Net investment income*	$23,767,830
Net realized and unrealized gain on investments	$34,180,128
Net increase in net assets resulting from operations	$57,947,958

*Net investment income includes $95,855 of pro forma additional expenses.

Annual Shareholder Report

Because the combined investment portfolios have been managed as a single integrated portfolio since the acquisition was completed, it is not practicable to separate the amounts of revenue and earnings of the Acquired Funds that have been included in the Fund's Statement of Operations as of March 31, 2010. The Fund received net assets from the Acquired Funds as the result of the tax-free reorganization as follows:

	Shares of the Fund Issued	Acquired Funds Net Assets Received	Unrealized Appreciation/ (Depreciation)1	Net Assets of the Fund Immediately Prior to Combination	Net Assets of the Fund Immediately After Combination
Federated California Municipal Income Fund	5,926,221	$59,262,137	$(210,182)
Federated North Carolina Municipal Income Fund	4,831,425	48,313,584	1,350,084
TOTAL	10,757,646	$107,575,721	$1,139,902	$471,631,337	$579,207,058

1 Unrealized appreciation/(depreciation) is included in the Acquired Funds Net Assets Received amount shown above.

On December 19, 2008, the Fund received assets from Suburban Common Trust Fund as the result of a tax-free reorganization, as follows:

Shares of the Fund Issued	Suburban Common Trust Fund Net Assets Received	Unrealized Appreciation2	Net Assets of the Fund Immediately Prior to Combination	Net Assets of the Fund Immediately After Combination
2,973,450	$26,909,721	$522,610	$402,063,122	$428,972,843

2 Unrealized Appreciation is included in the Suburban Common Trust Fund Net Assets Received amount shown above.

2. Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. These policies are in conformity with U.S. generally accepted accounting principles (GAAP).

Investment Valuation

In calculating its net asset value (NAV), the Fund generally values investments as follows:

• Fixed-income securities acquired with remaining maturities greater than 60 days are fair valued using price evaluations provided by a pricing service approved by the Directors.
• Fixed-income securities acquired with remaining maturities of 60 days or less are valued at their cost (adjusted for the accretion of any discount or amortization of any premium).
• Shares of other mutual funds are valued based upon their reported NAVs.
• Derivative contracts listed on exchanges are valued at their reported settlement or closing price.
• Over-the-counter (OTC) derivative contracts are fair valued using price evaluations provided by a pricing service approved by the Directors.

Annual Shareholder Report

46

If the Fund cannot obtain a price or price evaluation from a pricing service for an investment, the Fund may attempt to value the investment based upon the mean of bid and asked quotations or fair value the investment based on price evaluations, from one or more dealers. If any price, quotation, price evaluation or other pricing source is not readily available when the NAV is calculated, the Fund uses the fair value of the investment determined in accordance with the procedures described below. There can be no assurance that the Fund could purchase or sell an investment at the price used to calculate the Fund's NAV.

Fair Valuation and Significant Events Procedures

The Directors have authorized the use of pricing services to provide evaluations of the current fair value of certain investments for purposes of calculating the NAV. Factors considered by pricing services in evaluating an investment include the yields or prices of investments of comparable quality, coupon, maturity, call rights and other potential prepayments, terms and type, reported transactions, indications as to values from dealers and general market conditions. Some pricing services provide a single price evaluation reflecting the bid-side of the market for an investment (a “bid” evaluation). Other pricing services offer both bid evaluations and price evaluations indicative of a price between the prices bid and asked for the investment (a “mid” evaluation). The Fund normally uses bid evaluations for U.S. Treasury and Agency securities, mortgage-backed securities and municipal securities. The Fund normally uses mid evaluations for other types of fixed-income securities and OTC derivative contracts. In the event that market quotations and price evaluations are not available for an investment, the fair value of the investment is determined in accordance with procedures adopted by the Directors.

The Directors also have adopted procedures requiring an investment to be priced at its fair value whenever the Adviser determines that a significant event affecting the value of the investment has occurred between the time as of which the price of the investment would otherwise be determined and the time as of which the NAV is computed. An event is considered significant if there is both an affirmative expectation that the investment's value will change in response to the event and a reasonable basis for quantifying the resulting change in value. Examples of significant events that may occur after the close of the principal market on which a security is traded, or after the time of a price evaluation provided by a pricing service or a dealer, include:

• With respect to price evaluations of fixed-income securities determined before the close of regular trading on the NYSE, actions by the Federal Reserve Open Market Committee and other significant trends in U.S. fixed-income markets;
• Political or other developments affecting the economy or markets in which an issuer conducts its operations or its securities are traded; and
• Announcements concerning matters such as acquisitions, recapitalizations, litigation developments, a natural disaster affecting the issuer's operations or regulatory changes or market developments affecting the issuer's industry.

The Fund may seek to obtain more current quotations or price evaluations from alternative pricing sources. If a reliable alternative pricing source is not available, the Fund will determine the fair value of the investment using another method approved by the Directors.

Investment Income, Gains and Losses, Expenses and Distributions

Investment transactions are accounted for on a trade-date basis. Realized gains and losses from investment transactions are recorded on an identified-cost basis. Interest income and expenses are accrued daily. Distributions to shareholders are recorded on the ex-dividend date. Distributions of net investment income are declared daily and paid monthly. Non-cash Annual Shareholder Report

47

dividends included in dividend income, if any, are recorded at fair value. Investment income, realized and unrealized gains and losses and certain fund-level expenses are allocated to each class based on relative average daily net assets, except that each class may bear certain expenses unique to that class such as account administration, distribution services and shareholder services fees. Dividends are declared separately for each class. No class has preferential dividend rights; differences in per share dividend rates are generally due to differences in separate class expenses.

Premium and Discount Amortization

All premiums and discounts on fixed-income securities are amortized/accreted for financial statement purposes.

Federal Taxes

It is the Fund's policy to comply with the Subchapter M provision of the Internal Revenue Code and to distribute to shareholders each year substantially all of its income. Accordingly, no provision for federal income tax is necessary. As of and during the year ended March 31, 2010, the Fund did not have a liability for any uncertain tax positions. The Fund recognizes interest and penalties, if any, related to tax liabilities as income tax expense in the Statement of Operations. As of March 31, 2010, tax years 2007 through 2010 remain subject to examination by the Fund's major tax jurisdictions, which include the United States of America, the state of Maryland and the Commonwealth of Pennsylvania.

Other Taxes

As an open-end management investment company incorporated in the state of Maryland but domiciled in the Commonwealth of Pennsylvania, the Fund is subject to the Pennsylvania Franchise Tax. This franchise tax is assessed annually on the value of the Fund, as represented by average net assets for the tax year.

When-Issued and Delayed Delivery Transactions

The Fund may engage in when-issued or delayed delivery transactions. The Fund records when-issued securities on the trade date and maintains security positions such that sufficient liquid assets will be available to make payment for the securities purchased. Securities purchased on a when-issued or delayed delivery basis are marked to market daily and begin earning interest on the settlement date. Losses may occur on these transactions due to changes in market conditions or the failure of counterparties to perform under the contract.

Restricted Securities

The Fund may purchase securities which are considered restricted. Restricted securities are securities that either: (a) cannot be offered for public sale without first being registered, or being able to take advantage of an exemption from registration, under the Securities Act of 1933; or (b) are subject to contractual restrictions on public sales. In some cases, when a security cannot be offered for public sale without first being registered, the issuer of the restricted security has agreed to register such securities for resale, at the issuer's expense, either upon demand by the Fund or in connection with another registered offering of the securities. Many such restricted securities may be resold in the secondary market in transactions exempt from registration. Restricted securities may be determined to be liquid Annual Shareholder Report

48

under criteria established by the Directors. The Fund will not incur any registration costs upon such resales. The Fund's restricted securities are valued at the price provided by dealers in the secondary market or, if no market prices are available, at the fair value as determined in accordance with procedures established by and under the general supervision of the Directors.

Additional information on restricted securities, excluding securities purchased under Rule 144A, if applicable, that have been deemed liquid by the Directors, held at March 31, 2010, is as follows:

Security	Acquisition Date	Acquisition Cost	Market Value
California Statewide Communities Development Authority, Revenue Bonds (Series 2001), 6.75% (St. Mark's School), 6/1/2028	7/3/2001	$455,000	$438,151
California Statewide Communities Development Authority, Revenue Bonds, 6.50% (Turningpoint School)/(United States Treasury PRF 5/1/2010@102), 11/1/2031	3/23/2001	$500,000	$512,565

Other

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, expenses and revenues reported in the financial statements. Actual results could differ from those estimated.

4. Federal Tax Information

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences are due in part to differing treatments for discount accretion/premium amortization on debt securities, expiration of capital loss carryforwards and capital loss carryforwards acquired in mergers.

Annual Shareholder Report

50

For the year ended March 31, 2010, permanent differences identified and reclassified among the components of net assets were as follows:

Increase (Decrease)
Paid-In Capital	Undistributed Net Investment Income (Loss)	Accumulated Net Realized Gain (Loss)
$6,711,520	$403,109	$(7,114,629)

Net investment income (loss), net realized gains (losses) and net assets were not affected by this reclassification.

The tax character of distributions as reported on the Statement of Changes in Net Assets for the years ended March 31, 2010 and 2009, was as follows:

	2010	2009
Tax-exempt income	$20,854,605	$19,252,130
Ordinary income	$6,363	$ —

As of March 31, 2010, the components of distributable earnings on a tax basis were as follows:

Distributions in excess of tax-exempt income	$(1,412)
Net unrealized appreciation	$17,099,227
Capital loss carryforwards and deferrals	$(27,369,626)

The difference between book-basis and tax-basis net unrealized appreciation/depreciation is attributable to differing treatments for discount accretion/premium amortization on debt securities.

At March 31, 2010, the cost of investments for federal tax purposes was $553,097,915. The net unrealized appreciation of investments for federal tax purposes was $17,099,227. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $24,296,639 and net unrealized depreciation from investments for those securities having an excess of cost over value of $7,197,412.

At March 31, 2010, the Fund had a capital loss carryforward of $27,182,039 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code and thus will reduce the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Pursuant to the Code, such capital loss carryforward will expire as follows:

Expiration Year	Expiration Amount
2011	$ 749,272
2012	$ 451,499
2014	$ 286,453
2015	$ 515,345
2016	$ 1,949,184
2017	$16,161,827
2018	$ 7,068,459

Annual Shareholder Report

51

As a result of the tax-free transfer of assets from Federated Vermont Municipal Income Fund, Sentinel Tax-Free Income Fund, Federated California Municipal Income Fund and Federated North Carolina Municipal Income Fund, the use of certain capital loss carryforwards listed above may be limited.

Capital loss carryforwards of $562,757 expired during the year ended March 31, 2010.

Under current tax regulations, capital losses on securities transactions realized after October 31 may be deferred and treated as occurring on the first day of the following fiscal year. As of March 31, 2010, for federal income tax purposes, post October losses of $187,587 were deferred to April 1, 2010.

5. Investment Adviser Fee and Other Transactions with Affiliates

Investment Adviser Fee

Federated Investment Management Company is the Fund's investment adviser (the “Adviser”). The advisory agreement between the Fund and the Adviser provides for an annual fee equal to: (a) 0.30% of the Fund's average daily net assets; and (b) 4.50% of the gross income of the Fund, excluding capital gains or losses. Subject to the terms described in the Expense Limitation note, the Adviser may voluntarily choose to waive any portion of its fee.

Administrative Fee

Federated Administrative Services (FAS), under the Administrative Services Agreement, provides the Fund with administrative personnel and services. The fee paid to FAS is based on the average aggregate daily net assets of certain Federated funds as specified below:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150%	on the first $5 billion
0.125%	on the next $5 billion
0.100%	on the next $10 billion
0.075%	on assets in excess of $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the year ended March 31, 2010, the net fee paid to FAS was 0.076% of average daily net assets of the Fund. FAS waived $7,768 of its fee.

Distribution Services Fee

The Fund has adopted a Distribution Plan (the “Plan”) pursuant to Rule 12b-1 under the Act. Under the terms of the Plan, the Fund will compensate Federated Securities Corp. (FSC), the principal distributor, from the daily net assets of the Fund's Class B Shares and Class C Shares to finance activities intended to result in the sale of these shares. The Plan provides that the Fund may incur distribution expenses at the following percentages of average daily net assets annually, to compensate FSC:

Share Class Name	Percentage of Average Daily Net Assets of Class
Class B Shares	0.75%
Class C Shares	0.75%

Annual Shareholder Report

52

Subject to the terms described in the Expense Limitation note, FSC may voluntarily choose to waive any portion of its fee. When FSC receives fees, it may pay some or all of them to financial intermediaries whose customers purchase shares. For the year ended March 31, 2010, FSC retained $41,550 of fees paid by the Fund.

Sales Charges

Front-end sales charges and contingent deferred sales charges (CDSC) do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, as applicable. For the year ended March 31, 2010, FSC retained $50,166 in sales charges from the sale of Class A Shares. FSC also retained $804 of CDSC relating to redemptions of Class A Shares, $2,601 relating to redemptions of Class C Shares and $11,258 relating to redemptions of Class F Shares.

Shareholder Services Fee

The Fund may pay fees (Service Fees) up to 0.25% of the average daily net assets of the Fund's Class A Shares, Class B Shares, Class C Shares and Class F Shares to financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. Subject to the terms described in the Expense Limitation note, FSSC may voluntarily reimburse the Fund for Service Fees. For the year ended March 31, 2010, FSSC voluntarily reimbursed $403,535 of Service Fees. For the year ended March 31, 2010, FSSC received $27,073 of fees paid by the Fund.

Interfund Transactions

During the year ended March 31, 2010, the Fund engaged in purchase and sale transactions with funds that have a common investment adviser (or affiliated investment advisers), common Directors/Trustees and/or common Officers. These purchase and sale transactions complied with Rule 17a-7 under the Act and amounted to $157,280,000 and $167,120,000, respectively.

Expense Limitation

The Adviser and its affiliates (which may include FSC, FAS and FSSC) have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (as shown in the financial highlights) paid by the Fund's Class A Shares, Class B Shares, Class C Shares and Class F Shares (after the voluntary waivers and reimbursements) will not exceed 0.87%, 1.76%, 1.76% and 0.87% (the “Fee Limit”), respectively, through the later of (the “Termination Date”): (a) May 31, 2011; or (b) the date of the Fund's next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Directors.

The LOC was made available for extraordinary or emergency purposes, primarily for financing redemption payments. Borrowings are charged interest at a rate offered to the Fund by PNC Bank at the time of the borrowing. As of March 31, 2010, there were no outstanding loans. During the year ended March 31, 2010, the Fund did not utilize the LOC.

8. Interfund Lending

Pursuant to an Exemptive Order issued by the Securities and Exchange Commission (SEC), the Fund, along with other funds advised by subsidiaries of Federated Investors, Inc., may participate in an interfund lending program. This program provides an alternative credit facility allowing the funds to borrow from other participating affiliated funds. As of March 31, 2010, there were no outstanding loans. During the year ended March 31, 2010, the program was not utilized.

9. Legal Proceedings

Since October 2003, Federated Investors, Inc. and related entities (collectively, “Federated”), and various Federated sponsored mutual funds (“Federated Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Federated Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court. Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Federated Funds. The Board of the Federated Funds retained the law firm of Dickstein Shapiro LLP to represent the Federated Funds in these lawsuits. Federated and the Federated Funds, and their respective counsel, have been defending this litigation, and none of the Federated Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Federated Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Federated Funds or other adverse consequences for the Federated Funds.

Report of Independent Registered Public Accounting Firm

TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF
FEDERATED MUNICIPAL SECURITIES FUND, INC:

We have audited the accompanying statement of assets and liabilities of Federated Municipal Securities Fund, Inc. (the “Fund”), including the portfolio of investments, as of March 31, 2010, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 2010, by correspondence with the custodian and others or by other appropriate auditing procedures where replies from others were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Federated Municipal Securities Fund, Inc. at March 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Evaluation and Approval of Advisory Contract - May 2009

Federated Municipal Securities Fund, Inc. (the “Fund”)

The Fund's Board reviewed the Fund's investment advisory contract at meetings held in May 2009. The Board's decision regarding the contract reflects the exercise of its business judgment on whether to continue the existing arrangements.

In this connection, the Federated funds' Board had previously appointed a Senior Officer, whose duties include specified responsibilities relating to the process by which advisory fees are to be charged to a Federated fund. The Senior Officer has the authority to retain consultants, experts, or staff as may be reasonably necessary to assist in the performance of his duties, reports directly to the Board, and may be terminated only with the approval of a majority of the independent members of the Board. The Senior Officer prepared and furnished to the Board an independent, written evaluation that covered topics discussed below. The Board considered that evaluation, along with other information, in deciding to approve the advisory contract.

During its review of the contract, the Board considered compensation and benefits received by the Adviser. This included the fees received for services provided to the Fund by other entities in the Federated organization and research services received by the Adviser from brokers that execute Federated fund trades, as well as advisory fees. The Board is also familiar with and considered judicial decisions concerning allegedly excessive investment advisory fees, which have indicated that the following factors may be relevant to an Adviser's fiduciary duty with respect to its receipt of compensation from a fund: the nature and quality of the services provided by the Adviser, including the performance of the fund; the Adviser's cost of providing the services; the extent to which the Adviser may realize “economies of scale” as a fund grows larger; any indirect benefits that may accrue to the Adviser and its affiliates as a result of the Adviser's relationship with a fund; performance and expenses of comparable funds; and the extent to which the independent Board members are fully informed about all facts the Board deems relevant bearing on the Adviser's services and fees. The Board further considered management fees (including any components thereof) charged to institutional and other clients of the Adviser for what might be viewed as like services, and the cost to the Adviser and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit and profit margins of the Adviser and its affiliates for supplying such services. The Board was aware of these factors and was guided by them in its review of the Fund's advisory contract to the extent it considered them to be appropriate and relevant, as discussed further below.

Annual Shareholder Report

62

The Board considered and weighed these circumstances in light of its substantial accumulated experience in governing the Fund and working with Federated on matters relating to the Federated funds, and was assisted in its deliberations by independent legal counsel. Throughout the year, the Board has requested and received substantial and detailed information about the Fund and the Federated organization that was in addition to the extensive materials that comprise and accompany the Senior Officer's evaluation. Federated provided much of this information at each regular meeting of the Board, and furnished additional reports in connection with the particular meeting at which the Board's formal review of the advisory contract occurred. Between regularly scheduled meetings, the Board also received information on particular matters as the need arose. Thus, the Board's consideration of the advisory contract included review of the Senior Officer's evaluation, accompanying data and additional reports covering such matters as: the Adviser's investment philosophy, revenue, profitability, personnel and processes; investment and operating strategies; the Fund's short- and long-term performance (in absolute terms, both on a gross basis and net of expenses, as well as in relationship to its particular investment program and certain competitor or “peer group” funds and/or other benchmarks, as appropriate), and comments on the reasons for performance; the Fund's investment objectives; the Fund's expenses (including the advisory fee itself and the overall expense structure of the Fund, both in absolute terms and relative to similar and/or competing funds, with due regard for contractual or voluntary expense limitations); the use and allocation of brokerage commissions derived from trading the Fund's portfolio securities (if any); and the nature, quality and extent of the advisory and other services provided to the Fund by the Adviser and its affiliates. The Board also considered the preferences and expectations of Fund shareholders and their relative sophistication; the continuing state of competition in the mutual fund industry and market practices; the range of comparable fees for similar funds in the mutual fund industry; the Fund's relationship to the Federated family of funds which include a comprehensive array of funds with different investment objectives, policies and strategies which are available for exchange without the incurrence of additional sales charges; compliance and audit reports concerning the Federated funds and the Federated companies that service them (including communications from regulatory agencies), as well as Federated's responses to any issues raised therein; and relevant developments in the mutual fund industry and how the Federated funds and/or Federated are responding to them. The Board's evaluation process is evolutionary. The criteria considered and the emphasis placed on relevant criteria change in recognition of changing circumstances in the mutual fund marketplace. Annual Shareholder Report

63

With respect to the Fund's performance and expenses in particular, the Board has found the use of comparisons to other mutual funds with comparable investment programs to be particularly useful, given the high degree of competition in the mutual fund business. The Board focused on comparisons with other similar mutual funds more heavily than non-mutual fund products or services because it is believed that they are more relevant. For example, other mutual funds are the products most like the Fund, they are readily available to Fund shareholders as alternative investment vehicles, and they are the type of investment vehicle in fact chosen and maintained by the Fund's investors. The range of their fees and expenses therefore appears to be a generally reliable indication of what consumers have found to be reasonable in the precise marketplace in which the Fund competes. The Fund's ability to deliver competitive performance when compared to its peer group was a useful indicator of how the Adviser is executing the Fund's investment program, which in turn assisted the Board in reaching a conclusion that the nature, extent, and quality of the Adviser's investment management services were such as to warrant continuation of the advisory contract. In this regard, the Senior Officer has reviewed Federated's fees for providing advisory services to products outside the Federated family of funds (e.g., institutional and separate accounts). He concluded that mutual funds and institutional accounts are inherently different products. Those differences include, but are not limited to, different types of targeted investors; being subject to different laws and regulations; different legal structures; different average account sizes; different associated costs; different portfolio management techniques made necessary by different cash flows; and portfolio manager time spent in review of securities pricing. The Senior Officer did not consider these fee schedules to be determinative in judging the appropriateness of mutual fund advisory contracts.

The Senior Officer reviewed reports compiled by Federated, using data supplied by independent fund ranking organizations, regarding the performance of, and fees charged by, other mutual funds, noting his view that comparisons to fund peer groups are highly important in judging the reasonableness of proposed fees.

For the periods covered by the report, the Fund's performance for the one-year period was above the median of the relevant peer group, and the Fund's performance fell below the median of the relevant peer group for the three-year and five-year period. The Board discussed the Fund's performance with the Adviser and recognized the efforts being undertaken by the Adviser. The Board will continue to monitor these efforts and the performance of the Fund.

Annual Shareholder Report

64

The Board also received financial information about Federated, including reports on the compensation and benefits Federated derived from its relationships with the Federated funds. These reports covered not only the fees under the advisory contracts, but also fees received by Federated's subsidiaries for providing other services to the Federated funds under separate contracts (e.g., for serving as the Federated funds' administrator). The reports also discussed any indirect benefit Federated may derive from its receipt of research services from brokers who execute Federated fund trades. In addition, the Board considered the fact that, in order for a fund to be competitive in the marketplace, Federated and its affiliates frequently waived fees and/or reimbursed expenses and have disclosed to fund investors and/or indicated to the Board their intention to do so in the future, where appropriate. Moreover, the Board receives regular reports regarding the institution or elimination of these voluntary waivers.

Federated furnished reports, requested by the Senior Officer, that reported revenues on a fund-by-fund basis and made estimates of the allocation of expenses on a fund-by-fund basis, using allocation methodologies specified by the Senior Officer. The Senior Officer noted that, although they may apply consistent allocation processes, the inherent difficulties in allocating costs (and the unavoidable arbitrary aspects of that exercise) and the lack of consensus on how to allocate those costs may render such allocation reports unreliable. The allocation reports were considered in the analysis by the Board but were determined to be of limited use.

The Board and the Senior Officer also reviewed a report compiled by Federated comparing profitability information for Federated to other publicly held fund management companies. In this regard, the Senior Officer noted the limited availability of such information, but nonetheless concluded that Federated's profit margins did not appear to be excessive and the Board agreed.

The Senior Officer's evaluation also discussed the notion of possible realization of “economies of scale” as a fund grows larger. The Board considered in this regard that the Adviser has made significant and long-term investments in areas that support all of the Federated funds, such as personnel and processes for the portfolio management, compliance, and risk management functions; and systems technology; and that the benefits of these efforts (as well as any economies, should they exist) were likely to be enjoyed by the fund complex as a whole. Finally, the Board also noted the absence of any applicable regulatory or industry guidelines on this subject, which (as discussed in the Senior Officer's evaluation) is compounded by the lack of any common industry practice or general pattern with respect to structuring fund advisory fees with “breakpoints” that serve to reduce the fee as the fund attains a certain size. The Senior Officer did not recommend institution of breakpoints in pricing Federated's fund advisory services at this time.

Annual Shareholder Report

65

It was noted in the materials for the Board meeting that for the period covered by the report, the Fund's investment advisory fee, after waivers and expense reimbursements, if any, was above the median of the relevant peer group. The Board reviewed the fees and other expenses of the Fund with the Adviser and was satisfied that the overall expense structure of the Fund remained competitive. The Board will continue to monitor advisory fees and other expenses borne by the Fund.

The Senior Officer's evaluation noted his belief that the information and observations contained in his evaluation supported a finding that the proposed management fees are reasonable, and that Federated appeared to provide appropriate administrative services to the Fund for the fees paid. Under these circumstances, no changes were recommended to, and no objection was raised to, the continuation of the Fund's advisory contract. The Board concluded that the nature, quality and scope of services provided the Fund by the Adviser and its affiliates were satisfactory.

In its decision to continue an existing investment advisory contract, the Board was mindful of the potential disruptions of the Fund's operations and various risks, uncertainties and other effects that could occur as a result of a decision to terminate or not renew an advisory contract. In particular, the Board recognized that many shareholders have invested in the Fund on the strength of the Adviser's industry standing and reputation and with the expectation that the Adviser will have a continuing role in providing advisory services to the Fund. Thus, the Board's approval of the advisory contract reflected the fact that it is the shareholders who have effectively selected the Adviser by virtue of having invested in the Fund.

The Board based its decision to approve the advisory contract on the totality of the circumstances and relevant factors and with a view to past and future long-term considerations. Not all of the factors and considerations identified above were necessarily relevant to the Fund, nor did the Board consider any one of them to be determinative. With respect to the factors that were relevant, the Board's decision to approve the contract reflects its determination that Federated's performance and actions provided a satisfactory basis to support the decision to continue the existing arrangements.

(e)(1)                      Audit Committee Policies regarding Pre-approval of Services.

The Audit Committee is required to pre-approve audit and non-audit services performed by the independent auditor in order to assure that the provision of such services do not impair the auditor’s independence.  Unless a type of service to be provided by the independent auditor has received general pre-approval, it will require specific pre-approval by the Audit Committee.  Any proposed services exceeding pre-approved cost levels will require specific pre-approval by the Audit Committee.

Certain services have the general pre-approval of the Audit Committee.  The term of the general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee specifically provides for a different period.  The Audit Committee will annually review the services that may be provided by the independent auditor without obtaining specific pre-approval from the Audit Committee and may grant general pre-approval for such services.  The Audit Committee will revise the list of general pre-approved services from time to time, based on subsequent determinations.  The Audit Committee will not delegate its responsibilities to pre-approve services performed by the independent auditor to management.

The Audit Committee has delegated pre-approval authority to its Chairman.  The Chairman will report any pre-approval decisions to the Audit Committee at its next scheduled meeting.  The Committee will designate another member with such pre-approval authority when the Chairman is unavailable.

AUDIT SERVICES

The annual Audit services engagement terms and fees will be subject to the specific pre-approval of the Audit Committee.  The Audit Committee must approve any changes in terms, conditions and fees resulting from changes in audit scope, registered investment company (RIC) structure or other matters.

In addition to the annual Audit services engagement specifically approved by the Audit Committee, the Audit Committee may grant general pre-approval for other Audit Services, which are those services that only the independent auditor reasonably can provide.  The Audit Committee has pre-approved certain Audit services, all other Audit services must be specifically pre-approved by the Audit Committee.

AUDIT-RELATED SERVICES

Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Company’s financial statements or that are traditionally performed by the independent auditor.  The Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor, and has pre-approved certain Audit-related services, all other Audit-related services must be specifically pre-approved by the Audit Committee.

TAX SERVICES

The Audit Committee believes that the independent auditor can provide Tax services to the Company such as tax compliance, tax planning and tax advice without impairing the auditor’s independence.  However, the Audit Committee will not permit the retention of the independent auditor in connection with a transaction initially recommended by the independent auditor, the purpose of which may be tax avoidance and the tax treatment of which may not be supported in the Internal Revenue Code and related regulations.  The Audit Committee has pre-approved certain Tax services, all Tax services involving large and complex transactions must be specifically pre-approved by the Audit Committee.

ALL OTHER SERVICES

With respect to the provision of services other than audit, review or attest services the pre-approval requirement is waived if:

(1)   The aggregate amount of all such services provided constitutes no more than five percent of the total amount of revenues paid by the registrant, the registrant’s adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant to its accountant during the fiscal year in which the services are provided;

(2)   Such services were not recognized by the registrant, the registrant’s adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant  at the time of the engagement to be non-audit services; and

(3)   Such services are promptly brought to the attention of the Audit Committee of the issuer and approved prior to the completion of the audit by the Audit Committee or by one or more members of the Audit Committee who are members of the board of directors to whom authority to grant such approvals has been delegated by the Audit Committee.

The Audit Committee may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, and would not impair the independence of the auditor.

The SEC’s rules and relevant guidance should be consulted to determine the precise definitions of prohibited non-audit services and the applicability of exceptions to certain of the prohibitions.

PRE-APPROVAL FEE LEVELS

Pre-approval fee levels for all services to be provided by the independent auditor will be established annually by the Audit Committee.  Any proposed services exceeding these levels will require specific pre-approval by the Audit Committee.

PROCEDURES

Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the independent auditor and the Principal Accounting Officer and/or Internal Auditor, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC’s rules on auditor independence.

(e)(2)                      Percentage of services identified in items 4(b) through 4(d) that were approved by the registrants audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:
