Proxy statement

Annual meeting of shareholders to be held on December 7, 2012

This proxy statement is furnished to the shareholders of Fort Dearborn Income Securities, Inc. (the "Fund") in connection with the Board of Directors' solicitation of proxies to be used at the annual meeting of shareholders of the Fund to be held on December 7, 2012, at 1:00 p.m., Central Time, at the principal executive offices of the Fund at One North Wacker Drive, 38th Floor, Chicago, Illinois 60606, or any adjournment or adjournments thereof. This proxy statement and the related proxy card will first be mailed to shareholders on or about November 2, 2012.

A majority of the shares outstanding and entitled to vote on October 9, 2012 represented in person or by proxy, must be present to establish a quorum for the transaction of business at the meeting. Abstentions and broker non-votes will be counted as shares present for purposes of determining whether a quorum is present. Broker non-votes are shares held in street name for which the broker indicates that instructions have not been received from the beneficial owners or other persons entitled to vote and for which the broker does not have discretionary voting authority. It is expected that abstentions and broker non-votes will have no effect on Proposal 1. In the event that a quorum is not present at the annual meeting, shareholders present in person or the persons named as proxies may propose one or more adjournments of the annual meeting to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of a majority of those shares represented at the annual meeting in person or by proxy. If the meeting is adjourned, notice need not be given of the adjourned meeting at which the adjournment is taken. At any adjourned meeting, the Fund may transact any business which might have been transacted at the original meeting.

The individuals named as proxies on the enclosed proxy card will vote in accordance with your direction as indicated thereon if your proxy card is received properly executed by you or by your duly appointed agent or attorney-in-fact. If you give no voting instructions, your shares will be voted FOR the five nominees for Director named herein, and, in the proxies' discretion, either FOR or AGAINST any other business that may properly arise at the annual meeting, including questions of adjournment. You may revoke any proxy card by attending the annual meeting in person, giving another proxy or submitting a written notice of revocation to Mark Kemper, the Fund's Secretary, at UBS Global Asset Management (Americas), Inc., One North Wacker Drive, Chicago, Illinois 60606. Unless you are attending the annual meeting in person, to be effective, your revocation must be received by the Fund prior to the meeting and must indicate your name and account number. If you attend the annual meeting in person you may, if you wish, vote by ballot at the meeting, thereby canceling any proxy previously given. If your shares are held by your bank or broker, then in order to vote in person at the annual meeting, you will need to obtain a "Legal Proxy" from your bank or broker and present it to the Inspector of Election at the meeting.

As of the record date, October 9, 2012, the Fund had 8,775,665 shares of common stock outstanding. The solicitation of proxies, the cost of which will be borne by the Fund, will be made

primarily by mail but also may include telephone and oral communications by regular employees of UBS Global Asset Management (Americas), Inc. ("UBS Global AM" or the "Advisor"), who will not receive any compensation therefor from the Fund. Each full share of the Fund outstanding is entitled to one vote, and each fractional share of the Fund outstanding is entitled to a proportionate share of one vote.

UBS Global AM serves as the Fund's investment advisor. UBS Global AM is an indirect wholly owned asset management subsidiary of UBS AG. UBS AG is an internationally diversified organization with headquarters in Zurich and Basel, Switzerland. UBS AG operates in many areas of the financial services industry. The principal business offices of UBS Global AM are located at One North Wacker Drive, Chicago, Illinois 60606 and 1285 Avenue of the Americas, New York, New York 10019.

Proposal 1. Election of directors

Proposal 1 relates to the election of Directors of the Fund. Management proposes the election of the five nominees named in the table on the following page. Each nominee has indicated his or her willingness to serve if elected. If elected, each nominee will hold office until the next annual meeting of shareholders or until his or her successor is elected and qualified, or until he or she resigns or is otherwise removed. All of the nominees currently serve as Directors of the Fund and were last elected Director at the Fund's December 2011 annual meeting of shareholders. As described more fully below, all of the nominees have significant experience managing investment vehicles. All of the Fund's nominees are also on the boards of other funds managed by UBS Global AM. They have had experience as senior officers and directors of major business corporations and other investment advisors.

Directors are elected by a plurality vote of shareholders. Unless you give contrary instructions on the enclosed proxy card, your shares will be voted FOR the election of all five nominees. If any of the nominees should withdraw or otherwise become unavailable for election, your shares will be voted FOR such other nominee or nominees as management may recommend.

Directors, including those who are not "interested persons" of the Fund as that term is defined by the Investment Company Act of 1940, as amended ("1940 Act") ("Independent Directors"), shall be elected by the affirmative vote of the holders of a plurality of the shares of the Fund cast in person or by proxy and entitled to vote thereon, provided a quorum is present, so that the nominees with the largest number of votes are elected as Fund Directors. There is no cumulative voting for the election of Directors. Proxies cannot be voted for a greater number of persons than the number of nominees named. None of the Directors or nominees beneficially owned 1% or more of the Fund's common stock

and none of the executive officers beneficially owned any shares of the Fund's common stock as of October 9, 2012. In addition, the Directors and executive officers, as a group, beneficially owned less than 1% of the outstanding common stock of the Fund as of October 9, 2012.

Listed in the table on the following page, for each nominee, is a brief description of the nominee's experience as a Director of the Fund, as applicable, and as a director or trustee of other funds, as well as other recent professional experience.

Each Independent Director receives, for his or her service to the UBS Family of Funds Complex, an annual retainer of $160,000 paid quarterly for serving as a Board member. The chairperson of the Board also receives an annual retainer of $20,000 from the UBS Family of Funds Complex for his or her service to the Board. In addition, the chairs of the Audit Committee and the Nominating, Compensation and Governance Committee receive an annual retainer of $15,000 and $7,500, respectively, for their service to the Board. The UBS Family of Funds Complex also reimburses each Director and officer for out-of-pocket expenses in connection with travel and attendance at Board meetings. No officer, director or employee of UBS Global AM or any of its affiliates presently receives any compensation from the Fund for acting as a Board member or officer.

Additional information

Information concerning independent registered public accounting firm

The Fund's financial statements for the fiscal year ended September 30, 2012 were audited by Ernst & Young LLP ("Ernst & Young"), independent registered public accounting firm. In addition, Ernst & Young prepares the Fund's federal and state annual income tax returns and provides certain non-audit services. The Audit Committee has considered whether the provision of those non-audit services is compatible with maintaining Ernst & Young's independence. In the past two fiscal years, the Audit Committee did not approve any services provided by Ernst & Young pursuant to Rule 2-01(c)(7)(i)(C) of Regulation S-X. The Board of Directors of the Fund has selected Ernst & Young as the independent registered public accounting firm for the Fund for the fiscal year ending September 30, 2012. Ernst & Young has been the Fund's independent registered public accounting firm since the fiscal year ended September 30, 2001. Ernst & Young has informed the Fund that it has no material direct or indirect financial interest in the Fund.

Representatives of Ernst & Young will be present at the meeting via telephone.

Pre-approval policies and procedures

The Audit Committee Charter contains the Audit Committee's pre-approval policies and procedures. Reproduced below is an excerpt from the Audit Committee Charter regarding pre-approval policies and procedures:

To carry out its purposes, the Audit Committee shall have the following duties and powers:

(a) To pre-approve the engagement of, and to recommend to the Board the engagement, retention or termination of, the independent auditors to provide audit, review or attest services to the Fund, and, in connection therewith, to review and evaluate the capabilities and independence of the auditors, and receive the auditors' specific representations as to their independence. In evaluating the auditor's qualifications, performance and independence, the Committee must, among other things, obtain and review a report by the auditors, at least annually, describing the following items: (i) all relationships between the independent auditors and the Fund, as well as with the Fund's investment advisor or any control affiliate of the investment advisor that provides ongoing services to the Fund; (ii) any material issues raised by the most recent internal quality control review, or peer review, of the audit firm, or by any inquiry or investigation by governmental or professional authorities, within the preceding five years, with respect to one or more independent audits carried out by the firm, and any steps taken to deal with any such issues; and (iii) the audit firm's internal quality control procedures.

(b) To pre-approve all non-audit services to be provided to the Fund by the independent auditors when, without such pre-approval, the auditors would not be independent of the Fund under applicable federal securities laws, rules or auditing standards.

(c) To pre-approve all non-audit services to be provided by the Fund's independent auditors to the Fund's investment advisor or to any entity that controls, is controlled by or is under common control with the Fund's investment advisor ("advisor affiliate") and that provides ongoing services to the Fund, when, without such pre-approval by the Committee, the auditors would not be independent of the Fund under applicable federal securities laws, rules or auditing standards.

(d) To establish, if deemed necessary or appropriate as an alternative to Committee pre-approval of services to be provided by the independent auditors as required by paragraphs (b) and (c) above, policies and procedures to permit such services to be pre-approved by other means, such as by action of a designated member or members of the Committee, subject to subsequent Committee review or oversight.

(e) To consider whether the non-audit services provided by the Fund's independent auditor to the Fund's investment advisor or any advisor affiliate that provides on-going services to the Fund, which services were not pre-approved by the Committee, are compatible with maintaining the auditors' independence.

Aggregate non-audit fees

For the fiscal years ended September 30, 2012 and September 30, 2011, the aggregate non-audit fees billed by Ernst & Young of $184,022 and $185,275, respectively, included non-audit services rendered on behalf of the Fund of $8,650 and $7,225, respectively, and non-audit services rendered on behalf of the Fund's investment advisor (not including any sub-advisor whose role is primarily portfolio management and is subcontracted with or overseen by another investment advisor) and any entity controlling, controlled by, or under common control with the investment advisor that provides ongoing services to the Fund of $175,372 and $178,050, respectively.

The Audit Committee has considered whether the provision of non-audit services that were rendered to the Fund's investment advisor (not including any sub-advisor whose role is primarily portfolio management and is subcontracted with or overseen by another investment advisor), and any entity controlling, controlled by, or under common control with the investment advisor that provides ongoing services to the Fund that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining Ernst & Young's independence.

Additional information about the board of directors

The Board of Directors (the "Board") of the Fund met seven times during the fiscal year ended September 30, 2012. Each Director attended 75% or more of the Board meetings during the last fiscal year. In addition, no Directors attended less than 75% of the aggregate of the total number of meetings held by the Board and the total number of meetings held by all committees on which such Director served during the fiscal year ended September 30, 2012.

The Fund's Directors are not required to attend the Fund's annual meetings. All four of the then current Directors attended the annual meeting of shareholders in 2011.

The Board of Directors of the Fund is responsible for establishing the Fund's policies and for overseeing the management of the Fund. The Board of Directors elects the officers of the Fund, who, along with third party service providers, are responsible for administering the day-to-day operations of the Fund. The Board of Directors of the Fund is comprised entirely of Independent Directors that are not considered to be "interested persons" by reason of their relationship with the Fund's management or otherwise as defined under the 1940 Act. Frank K. Reilly, an Independent Director, is Chairman of the Board. As Chairman of the Board, Mr. Reilly approves agendas for Board meetings and generally facilitates communication and coordination among the Independent Directors and between the Independent Directors and management. Mr. Reilly also acts as liaison between the

Fund's Chief Compliance Officer and the Independent Directors with respect to compliance matters between scheduled Board meetings.

The Board of the Fund meets in person at least four times each year. At each in-person meeting, the Independent Directors meet in executive session to discuss matters outside the presence of management. In addition, the Board holds special telephonic meetings throughout the year and the Independent Directors also discuss other matters on a more informal basis at other times.

The Board has three standing committees, an Audit Committee, a Performance Committee and a Nominating, Compensation and Governance Committee (the "Nominating Committee"). As described below, through these Committees, the Independent Directors have direct oversight of the Fund's accounting and financial reporting policies, historical and ongoing performance, the selection and nomination of candidates to the Fund's Board and the Fund's governance procedures.

The Fund's Audit Committee is responsible for, among other things: (i) selecting, overseeing and setting the compensation of the Fund's independent registered public accounting firm; (ii) overseeing the Fund's accounting and financial reporting policies and practices, its internal controls and, as appropriate, the internal controls of certain service providers; (iii) overseeing the quality and objectivity of the Fund's financial statements and the independent audits thereof; and (iv) acting as a liaison between the Fund's independent registered public accounting firm and the full Board of Directors. A copy of the Audit Committee Charter was included as an appendix to last year's proxy statement. In fulfilling its duties, the Audit Committee has: (a) reviewed and discussed the Fund's audited financial statements with management; (b) discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61; (c) received certain written disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1 and discussed the independent auditors' independence with them; and (d) based upon its review of the above, recommended to the Board that the Fund's audited financial statements be included in the Fund's annual report to shareholders for the fiscal year ended September 30, 2011. It is anticipated the Audit Committee will conduct similar discussions and review for the fiscal year ended September 30, 2012. The Audit Committee currently consists of Mmes. Cepeda and Smith and Messrs. Reilly, Roob and Thomas, none of whom have any relationship to the Fund that may interfere with the exercise of their independence from management or the Fund and each of whom is independent as defined under listing standards of the NYSE applicable to closed-end funds. Each member of the Fund's Audit Committee is also a member of a similar committee established by the boards of certain other investment companies for which UBS Global AM or an affiliate serves as investment advisor, sub-advisor or manager. The Audit Committee met five times during the fiscal year ended September 30, 2012.

The Fund's Performance Committee has the responsibility, among other things, to: (i) review quarterly reports on the investment performance of the Fund; (ii) review the investment performance benchmarks and peer group comparisons and any proposed changes to such benchmarks or peer groups for the Fund; (iii) review and consider proposed changes to investment objectives and strategies and the use of new financial instruments for the Fund; and (iv) review the kind, scope and format of, and the time periods covered by, the investment performance data and related reports. The Performance Committee currently consists of Ms. Smith and Mr. Reilly, neither of whom have any relationship to the Fund that may interfere with the exercise of their independence from management or the Fund. Each member of the Fund's Performance Committee is also a member of a similar committee established by the boards of certain other investment companies for which UBS Global AM

or an affiliate serves as investment advisor or manager. The Performance Committee was established in June 2012 and met one time during the fiscal year ended September 30, 2012.

The Board's Nominating Committee also acts pursuant to a written charter ("Nominating, Compensation and Governance Committee Charter"). The Nominating Committee is responsible for, among other things, selecting, evaluating and recommending to the Board candidates to be nominated as additional Independent Directors of the Board, periodically reviewing the composition of the Board, periodically reviewing Board governance procedures and recommending any appropriate changes thereto and periodically reviewing the compensation structure for Independent Directors. A copy of the Nominating, Compensation and Governance Committee Charter was included as an appendix to the Fund's 2010 proxy statement. The Nominating Committee currently consists of Mmes. Cepeda and Smith and Messrs. Reilly, Roob and Thomas, none of whom is an "interested person" for purposes of the 1940 Act, and all of whom are independent as defined under listing standards of the NYSE applicable to closed-end funds. The Nominating Committee met three times during the fiscal year ended September 30, 2012.

In nominating candidates, the Nominating Committee believes that no specific qualifications or disqualifications are controlling or paramount, or that specific qualities or skills are necessary for each candidate to possess. In identifying and evaluating nominees for Director, the Nominating Committee takes into consideration such factors as it deems appropriate. These factors may include: (i) whether or not the person is an "interested person" as defined in the 1940 Act, meets the applicable independence and experience requirements of the NYSE and is otherwise qualified under applicable laws and regulations to serve as a member of the Board; (ii) whether or not the person has any relationships that might impair his or her independence, such as any business, financial or family relationships with Fund management, the investment advisor of the Fund, other Fund service providers or their affiliates; (iii) whether or not the person is willing to serve, and willing and able to commit the time necessary for the performance of the duties of a Board member; (iv) the person's judgment, skill, diversity and experience with investment companies and other organizations of comparable purpose, complexity and size and subject to similar legal restrictions and oversight; (v) the interplay of the candidate's experience with the experience of other Board members; and (vi) the extent to which the candidate would be a desirable addition to the Board and any committees thereof.

While the Nominating Committee is solely responsible for the selection and recommendation to the Board of Board candidates, the Nominating Committee will consider nominees recommended by Qualifying Fund Shareholders if a vacancy occurs among those board members who are independent board members. A Qualifying Fund Shareholder is a shareholder that: (i) owns of record, or beneficially through a financial intermediary, 1/2 of 1% or more of the Fund's outstanding shares and (ii) has been a shareholder of at least 1/2 of 1% of the Fund's total outstanding shares for 12 months or more prior to submitting the recommendation to the Nominating Committee. In order to recommend a nominee, a Qualifying Fund Shareholder should send a letter to Adela Cepeda, the chairperson of the Nominating Committee, care of Mark Kemper, Secretary of the Fund, at UBS Global Asset Management (Americas), Inc., One North Wacker Drive, Chicago, Illinois 60606. The Qualifying Fund Shareholder's letter should include: (i) the name and address of the Qualifying Fund Shareholder making the recommendation; (ii) the number of shares of the Fund which are owned of record and beneficially by such Qualifying Fund Shareholder and the length of time that such shares have been so owned by the Qualifying Fund Shareholder; (iii) a description of all arrangements and understandings between such Qualifying Fund Shareholder and any other person or persons (naming

such person or persons) pursuant to which the recommendation is being made; (iv) the name and address of the nominee; and (v) the nominee's resume or curriculum vitae.

The Qualifying Fund Shareholder's letter must be accompanied by a written consent of the individual to stand for election if nominated for the Board and to serve if elected by shareholders. The Nominating Committee may also seek such additional information about the nominee as it considers appropriate, including information relating to such nominee that is required to be disclosed in solicitations or proxies for the election of board members.

The Board also at times creates other committees of Board members to assist in the evaluation of specific matters. The Independent Directors have also engaged independent legal counsel, and have from time to time engaged consultants and other advisors to assist them in performing their oversight responsibilities.

Shareholders may send other communications to the Board by sending a letter to the chairperson of the Board of Directors, Mr. Frank K. Reilly, care of Mark Kemper, Secretary of the Fund, at UBS Global Asset Management (Americas), Inc., One North Wacker Drive, Chicago, Illinois 60606. The chairperson of the Board of Directors will relay shareholder communications to the other Board members.

The Board believes that the existing Board structure for the Fund is appropriate because it allows the Independent Directors to exercise independent judgment in evaluating the governance of the Fund and performance of the Fund's service providers.

Board oversight of risk management

The Board, as a whole, considers risk management issues as part of its general oversight responsibilities throughout the year at regular board meetings, through regular reports that have been developed by Fund management and the Advisor. These reports address certain investment, valuation and compliance matters. The Board also may receive special written reports or presentations on a variety of risk issues, either upon the Board's request or upon the initiative of the Advisor, including discussions with the Advisor's Chief Risk Officer. In addition, the Audit Committee of the Board meets at least annually with the Advisor's internal audit group to discuss the results of the internal audit group's examinations of the functions and processes of the Advisor that affect the Fund and to be advised regarding the internal audit group's plans for upcoming audits.

With respect to investment risk, the Board receives regular written reports describing and analyzing the investment performance of the Fund. The Board discusses these reports and the performance of the Fund and investment risks with management of the Advisor at the Board's regular meetings. To the extent that the Advisor seeks to change the Fund's investment strategy that may have a material impact on the Fund's risk profile or invest in a new type of security or instrument, the Board generally is provided information on such proposed changes for the Board's approval.

With respect to valuation, the Advisor provides regular written reports to the Board that enables the Board to monitor fair valued securities in the Fund. Such reports also include information concerning illiquid securities held by the Fund. In addition, the Audit Committee reviews valuation procedures and pricing results with the Fund's independent registered public accounting firm in connection with such Committee's review of the results of the audit of the Fund's year end financial statements.

With respect to compliance risks, the Board receives regular compliance reports prepared by the Advisor's compliance group and meets regularly with the Fund's Chief Compliance Officer ("CCO") to discuss compliance issues, including compliance risks. As required under U.S. Securities and Exchange Commission ("SEC") rules, the Independent Directors meet at least quarterly in executive session with the CCO, and the Fund's CCO prepares and presents an annual written compliance report to the Board. The Board adopts compliance policies and procedures for the Fund and receives information about the procedures in place for the Fund's service providers. The compliance policies and procedures are specifically designed to detect and prevent violations of the federal securities laws.

At the request of the Board, the Advisor also has provided presentations to the Board with respect to the Advisor's operational risk management.

In addition, the Fund anticipates that its next annual meeting of shareholders will be held on or around the same date next year. Any shareholder who wishes to submit proposals for inclusion in the Fund's proxy statement and proxy card to be considered at the Fund's 2013 annual meeting of shareholders should send such proposals to Mark Kemper, the Secretary of the Fund, at UBS Global Asset Management (Americas), Inc., One North Wacker Drive, Chicago, Illinois 60606.
