PROXY STATEMENT
2017 ANNUAL MEETING OF STOCKHOLDERS

        The proxy card that accompanies this proxy statement is being solicited by the board of directors (the "Board") of American Capital Senior Floating, Ltd., a Maryland corporation (the "Company," "we," "us" or "our"), for use at the Company's 2017 Annual Meeting of Stockholders (the "Annual Meeting") to be held on December 14, 2017 at 10:00 a.m., Eastern Time, at the offices of Proskauer Rose LLP, Eleven Times Square, New York, New York 10036, or at any adjournment or postponement thereof. This proxy statement, the Notice of Annual Meeting of Stockholders and the accompanying proxy card are first being released to the Company's stockholders on or about November 3, 2017 and include the Company's Annual Report on Form 10-K, which includes audited financial statements for the year ended December 31, 2016.

        We encourage you to vote your shares, either by voting in person at the Annual Meeting or by granting a proxy (i.e., authorizing someone to vote your shares). If you properly authorize your proxy and the Company receives it in time for the Annual Meeting, the persons named as proxies will vote the shares registered directly in your name in the manner that you specify. If no specification is made, the votes entitled to be cast by such shares will be cast FOR the election of the four director nominees and FOR the ratification of Ernst & Young LLP as the Company's independent registered public accounting firm for the year ending December 31, 2017.

        Any stockholder "of record" (i.e., stockholders holding shares directly in their name) giving a valid proxy for the Annual Meeting may revoke it before it is exercised by giving a later-dated properly executed proxy, by giving notice of revocation to the Company in writing before or at the Annual Meeting or by attending the Annual Meeting and voting in person. However, the mere presence of the stockholder at the Annual Meeting does not revoke the proxy. If your shares are held for your account by a broker, bank or other institution or nominee, you may vote such shares at the Annual Meeting only if you obtain proper written authority from your institution or nominee and present it at the meeting. If your shares are held for your account by a broker, bank or other institution or nominee, to revoke any voting instructions prior to the time the vote is taken at the Annual Meeting, you must contact such broker, bank or other institution or nominee to determine how to revoke your vote in accordance with its policies a sufficient time in advance of the Annual Meeting.

        Unless revoked as stated above, the shares of common stock represented by valid proxies will be voted on all matters to be acted upon at the Annual Meeting. With respect to the election of directors, proxies cannot be voted for a greater number of persons than the number of nominees named.

        The Board is not aware of any matter to be presented for action at the Annual Meeting other than the matters set forth herein. Should any other matter requiring a vote of stockholders arise, it is the intention of the persons named in the proxy to vote in accordance with their discretion on such

1

---

matters. Stockholders have no dissenters' or appraisal rights in connection with any of the proposals described herein.

        The record date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on October 19, 2017. As of October 19, 2017, there were 10,000,100 shares of the Company's common stock outstanding. Each share of common stock has one vote. The presence, in person or by proxy, of the holders of shares of common stock of the Company entitled to cast a majority of the votes entitled to be cast shall constitute a quorum for the purposes of the Annual Meeting. If there are not sufficient votes for a quorum or to approve or ratify any of the foregoing proposals at the time of the Annual Meeting, the chairman of the meeting may adjourn the Annual Meeting in order to permit further solicitation of proxies by the Company.

        Abstentions and broker non-votes will be deemed to be present for the purpose of determining a quorum for the Annual Meeting. However, abstentions and broker non-votes are not counted as votes cast. A "broker non-vote" with respect to a matter occurs when a broker, bank or other institution or nominee holding shares on behalf of a beneficial owner has not received voting instructions from the beneficial owner on a particular proposal and does not have, or chooses not to exercise, discretionary authority to vote the shares on such proposals.

        You may vote "For" or "Against," or abstain from voting on, Proposal 1 (to elect the board of directors, each director to serve until the next annual meeting of stockholders, and until their successors are duly elected and qualify). The affirmative vote of a majority of all of the votes cast by holders of our common stock at a meeting at which a quorum is present is required under the Company's Bylaws (as amended, the "Bylaws") to elect each director in Proposal 1 (meaning that the number of votes cast "For" a director nominee must exceed the votes cast "Against" that nominee). For purposes of the vote on Proposal 1, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote. If an incumbent director nominee does not receive the required number of votes for re-election, then under Maryland law, he or she will continue to serve as a director of the Company until his or her successor is duly elected and qualifies.

        You may vote "For" or "Against," or abstain from voting on, Proposal 2 (to ratify the selection of Ernst & Young LLP as the Company's independent registered public accounting firm). The affirmative vote of a majority of all of the votes cast by holders of our common stock at a meeting at which a quorum is present is required under the Bylaws for approval of Proposal 2 (meaning that the number of shares voted "For" the proposal must exceed the number of shares voted "Against" the proposal). For purposes of the vote on Proposal 2, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote.

        The Company will bear the cost of solicitation of proxies in the form accompanying this statement. Proxies will be solicited by mail or by requesting brokers and other custodians, nominees and fiduciaries to forward proxy soliciting material to the beneficial owners of shares of common stock held of record by such brokers, custodians, nominees and fiduciaries, each of whom the Company will reimburse for its expenses in so doing. In addition to the use of mail, directors, officers and regular employees of Ivy Hill Asset Management, L.P., the Company's investment adviser ("IHAM," the "investment adviser" or our "Manager") without special compensation therefor, may solicit proxies personally or by telephone, electronic mail, facsimile or other electronic means from stockholders. The address of IHAM is 245 Park Avenue, 42nd Floor, New York, NY 10167. You may also be asked if you would like to authorize your proxy over the telephone and to have your voting instructions transmitted to the Company's proxy tabulation firm.

PROPOSAL 1: ELECTION OF DIRECTORS

        Under the Company's charter (as amended, the "Charter") and the Bylaws (together with the Charter, the "Charter Documents"), the Company's directors are elected annually for a one-year term. Each director will hold office for the term to which he or she is elected and until his or her successor is duly elected and qualifies.

        The terms of Phyllis R. Caldwell, Gil Crawford, Larry K. Harvey and Kevin R. Braddish will expire at the Annual Meeting and the Compensation and Corporate Governance Committee has recommended, and the Board has nominated, Messrs. Braddish, Crawford and Harvey and Ms. Caldwell to stand for re-election at the Annual Meeting and to hold office until the annual meeting to be held in 2018 and until their successors are duly elected and qualify. Messrs. Braddish, Crawford and Harvey and Ms. Caldwell have agreed to serve as directors if elected and have consented to be named as nominees.

        The election of directors nominated in Proposal 1 requires the affirmative vote of a majority of all of the votes cast by holders of our common stock at a meeting at which a quorum is present. The affirmative vote of a "majority" of the votes cast means that the number of votes cast "for" a director nominee must exceed the votes cast "against" that nominee. In the context of the election of four directors at the Annual Meeting, it will mean that each of the four candidates will be required to receive more votes "for" than "against" to be elected. Abstentions and broker non-votes will have no effect on the outcome of the proposal.

        A stockholder can vote for or against or abstain from voting with respect to each such nominee. In the absence of instructions to the contrary, it is the intention of the persons named as proxies to vote such proxy FOR the election of the nominees named herein. If any nominee should decline or be unable to serve as a director, it is intended that the proxy will be voted for the election of such person as is nominated as a replacement by the Compensation and Corporate Governance Committee and by the Board. The Board has no reason to believe that any nominee will be unable or unwilling to serve.

        The Board recommends that you vote FOR the election of Phyllis R. Caldwell, Gil Crawford, Larry K. Harvey and Kevin R. Braddish as directors of the Company for the term for which they have been nominated.

Information about the Director Nominees, the Directors, and the Executive Officers and Certain Other Officers

        The following information as of October 27, 2017 was furnished to the Company by each currently serving director (including each currently serving director who is also a director nominee), each director nominee, each executive officer and each other listed officer, and sets forth the name, age, principal occupation or employment of each such person, all positions and offices such person has held with the Company, and the period during which he or she has served as a director, executive officer or other listed officer of the Company.

        The Company divides its directors into two groups—interested directors and independent directors.

CORPORATE GOVERNANCE

        Our Board is currently comprised of three independent directors and one interested director. The following table sets forth the current members of our Board and their committee membership, if any:

Board Leadership Structure

        We believe that our Board's independent oversight continues to be substantial. Our Board has determined that all of the current directors, except Mr. Braddish, are "independent" as defined in the NASDAQ rules. Similarly, only Mr. Braddish is an "interested person" of the Company under the Investment Company Act.

        It is our Board's policy to have a majority of our directors who are not "interested persons" meet regularly without persons who are members of management or employee directors present to facilitate the Board's effective independent oversight of management. These directors periodically designate a director who is "independent," as defined in the NASDAQ rules, to serve as the "lead independent director" and preside at these meetings. Presently, our independent directors meet during our Board's quarterly meetings and may hold additional meetings at the request of the lead independent director or another independent director. The designation of a lead independent director is generally for a one-year term or until his or her successor is elected, and a lead independent director may be re-appointed at the end of a term. If the lead independent director is unavailable for a meeting, his or her immediate predecessor will serve as lead independent director for such meeting. Mr. Crawford is our current lead independent director.

        Each of our Board's Audit and Compliance Committee and Compensation and Corporate Governance Committee is composed entirely of independent directors. These independent committees of our Board also have the authority under their respective charters to hire independent advisors and consultants, at our expense, to assist them in performing their duties.

Corporate Governance

        Our Board has developed corporate governance practices to help it fulfill its responsibility to stockholders to oversee the work of management in the conduct of our business. The governance

15

---

practices are memorialized in corporate governance guidelines to assure that the Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of management. These guidelines, in conjunction with our Charter, our Bylaws and committee charters of the Audit and Compliance Committee and the Compensation and Corporate Governance Committee, form the framework for our governance. All of these documents are available in the Investor Relations section of our web site at www.ACSF.com.

Committees of the Board

        Our Board's principal standing committees and their primary functions are described below.

Audit and Compliance Committee

        This committee assists the Board in overseeing:

•

our accounting and financial reporting processes;



•

the integrity and audits of our financial statements;



•

the adequacy of our internal controls over financial reporting, including information technology security and controls relating to the preparation of our financial statements;



•

our compliance with legal and regulatory requirements;



•

the qualifications and independence of our independent registered public accounting firm; and



•

the performance of our independent registered public accounting firm and any internal auditors.

        In addition, the Audit and Compliance Committee reviews and provides a recommendation to the Board with regard to its approval of the valuations of our investments presented by management. In such review, the committee discusses the proposed valuations with our independent auditors and other relevant consultants. The Audit and Compliance Committee is also responsible for engaging an independent registered public accounting firm, reviewing with the independent registered public accounting firm the plans and results of the audit engagement, approving professional services provided by the independent registered public accounting firm and considering the range of audit and non-audit fees. The committee's meetings include, whenever appropriate, executive sessions with each of our independent external auditors and our Manager's internal auditors, without the presence of management.

16

---

Compensation and Corporate Governance Committee

        This committee's principal functions are to:

•

evaluate the performance of and compensation paid by us, if any, to our executive officers;



•

evaluate the performance of our Manager;



•

review the compensation and fees payable to our Manager under the management agreement with our Manager;



•

decide whether to recommend the renewal or termination of the management agreement with our Manager;



•

evaluate the compensation and fees payable to the members of the Board;



•

administer any equity incentive plans that we may adopt, to the extent it is delegated authority by the Board;



•

review and assist with the development of our executive succession plans; and



•

produce a report on executive compensation required to be included in our proxy statement for our annual meetings if required.

        The Compensation and Corporate Governance Committee also serves as the Board's standing nominating committee and as such performs the following functions:

•

identifying, recruiting and recommending to the Board qualified candidates for election as directors and recommending a slate of nominees for election as directors by our common stockholders at the annual meeting of stockholders;



•

developing and recommending to the Board corporate governance guidelines, including the committee's selection criteria for director nominees;



•

reviewing and making recommendations on matters involving the general operation of the Board and our corporate governance;



•

recommending to the Board nominees for each committee of the Board; and



•

annually facilitating the assessment of the Board's performance as a whole and of the individual directors and reports thereon to the Board.

Board and Committee Meetings

        Under our Bylaws and Maryland law, the Board is permitted to take actions at regular or special meetings and by written consent. The Board generally holds regular quarterly meetings and meets on other occasions as necessary. The Board held six meetings during 2016. As noted above, the independent directors also met separately in executive sessions to discuss various matters, including our performance and the performance of our Manager.

        Each of the Audit and Compliance Committee and the Compensation and Corporate Governance Committee schedules regular meetings to coincide with the quarterly meetings of the Board and also meets at the request of senior management or at such other times as it determines. Our Secretary, in consultation with the chair of each committee, sets agendas for the meetings. Each committee reports regularly to the Board on its activities at the next regularly scheduled Board meeting following their committee meetings and when appropriate. During 2016, the Audit and Compliance Committee held five meetings and the Compensation and Corporate Governance Committee held one meeting.

        Each of our directors attended at least 80% of the meetings of the Board and 100% of the meetings of the committees during the period for which he or she was a director and a member of the

17

---

respective committees on which he or she served during 2016. Although we do not have a policy on director attendance at our annual meeting, directors are encouraged to attend our annual meeting. Each one of our directors attended the 2016 annual meeting either in person or by telephonic conference call.

Risk Oversight

        One of the roles of our Board is being responsible for the general oversight of the Company, including the performance of our executive officers, our Manager and the Company's risk management processes, to assure that the long-term interests of our stockholders are being served. In performing its risk oversight function, the Board, directly or through its standing committees or by working with our Chief Compliance Officer, regularly reviews our material strategic, operational, financial, compensation and compliance risks with senior management. The Company believes that the Board's role in risk management oversight is effective and appropriate, particularly given the extensive regulation to which it is already subject as a business development company ("BDC") under the Investment Company Act and a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). For instance, the Board receives updates at each regular meeting on the Company's performance and other recent developments, including, among other things, the risks and opportunities facing us, as well as our investment portfolio. The Board has also adopted, and regularly reviews our compliance with, various policies and procedures addressing other operational risks, such as business continuity, data privacy and cybersecurity. In addition, the Board routinely receives information regarding the technology and cyber-risks relevant to the Company's business to ensure that adequate steps are being taken to prevent, and prepare for, cyber-incidents.

        The Board also recognizes the importance of effective executive leadership to our success and is actively engaged in overseeing the operational risks related to succession planning. The Board routinely discusses staffing for critical roles, and potential replacements for key personnel are given exposure to the Board during meetings and other events. In addition, the Board is regularly updated on the Manager's strategies for recruiting, developing and retaining outstanding personnel at the Manager and its affiliates and minimizing employee turnover, as applicable.

        The Board has delegated certain risk management oversight responsibility to its committees as follows:

•

Regulatory Compliance Risk:  The Board, both directly and through the Audit and Compliance Committee, receives regular reports from our Manager's legal, accounting and internal audit representatives on regulatory matters, including the Company's compliance with the BDC qualification and leverage requirements under the Investment Company Act and the RIC income and asset diversification requirements under the Code, compliance with our Code of Ethics and Conduct ("Code of Ethics") and our Manager's compliance with the Investment Advisers Act of 1940.



•

Financial and Accounting Risk:  The Audit and Compliance Committee oversees the Company's management of its financial, accounting, internal controls and liquidity risks through regular meetings with our Chief Financial Officer, senior representatives of our Manager's and its affiliates' accounting, tax, auditing and legal departments and representatives of the Company's independent public accountant.



•

Litigation Risk:  The Compensation and Corporate Governance Committee monitors the Company's litigation, if any.



•

Compensation and Benefit Plan Risk:  The Compensation and Corporate Governance Committee considers the extent to which our director compensation and any benefit plan programs that we may adopt may create risk for the Company.

18

---

•

Governance Risk:  The Compensation and Corporate Governance Committee also oversees risks related to Board organization, membership and structure and corporate governance.

        The Board also performs its risk management oversight function by working with our Chief Compliance Officer to monitor risk and compliance in accordance with the Investment Company Act and our policies and procedures. The Chief Compliance Officer reviews, at least annually, the adequacy and effectiveness of our compliance policies and procedures and those of certain of our service providers, including our Manager, and provides a written report to the Board. The Chief Compliance Officer's report, which is reviewed by and discussed with the Board, addresses at a minimum (i) the operation of such policies and procedures since the last report; (ii) any material changes to such policies and procedures since the last report; (iii) any recommendations for material changes to such policies and procedures as a result of the Chief Compliance Officer's review; and (iv) any compliance matter that has occurred since the date of the last report about which the Board would reasonably need to know to oversee our compliance activities and risks. In addition, the Chief Compliance Officer reports to the Board periodically on material compliance matters and meets separately in executive session with the independent directors at least once each year.

Communications Between Stockholders and the Board of Directors

        The Board welcomes communications from the Company's stockholders. Stockholders may send communications to the Board, or to any particular director, to the following address: c/o American Capital Senior Floating, Ltd., 245 Park Avenue, 42nd Floor, New York, New York 10167. Stockholders should indicate clearly the director or directors to whom the communication is being sent so that each communication may be forwarded directly to the appropriate director(s).

COMPENSATION DISCUSSION

Director Compensation

        We were incorporated in Maryland on February 6, 2013 and commenced operations on October 15, 2013. We completed our initial public offering ("IPO") on January 22, 2014. Ms. Caldwell and Messrs. Crawford and Harvey were appointed to the Board on January 13, 2014 in connection with our IPO. Mr. Braddish was appointed to the Board on January 3, 2017 to fill the vacant seat created by Malon Wilkus' resignation.

19

---

        We compensate our non-employee directors with cash retainers. Any member of our Board who is an employee of the Company, Ares Management, or any of its affiliates, including IHAM, does not receive compensation from us for his or her Board service. The Compensation and Corporate Governance Committee periodically reviews the form and amount of compensation paid to our non-employee directors against peer companies and group and general industry data and makes recommendations for adjustments, as appropriate, to the full Board. During 2016, each such non-employee director was paid a retainer for service on the Board at an annual rate of $60,000, payable quarterly in advance. In addition, the Chair of our Audit and Compliance Committee was paid a retainer at an annual rate of $15,000, the Chair of our Compensation and Corporate Governance Committee was paid an annual retainer of $10,000, and our lead independent director was paid an annual retainer of $10,000, each payable quarterly in advance. During 2016, directors were reimbursed for travel expenses incurred in connection with Board and committee meetings and Board-related functions.

        The following table sets forth the compensation received by each non-employee director during 2016:

(1)

Mr. Lundine resigned from the Board on January 3, 2017.

Executive Compensation

        Our executive officers do not receive any direct compensation from us. We do not currently have any employees and do not currently expect to have any employees. Services necessary for our business are provided by individuals who are employees or other affiliates of IHAM, our investment adviser, pursuant to the terms of the Management Agreement. Each of our executive officers is an employee or other affiliate of our investment adviser. Our day-to-day investment operations are managed by our investment adviser. Most of the services necessary for the origination and administration of our investment portfolio are provided by individuals employed by our investment adviser. In addition, we reimburse our investment adviser for certain expenses under the Management Agreement. We previously were managed by American Capital ACSF Management, LLC ("ACSF Management") pursuant to the terms of a management agreement dated January 15, 2014 between us and ACSF Management (the "Prior Management Agreement"). The terms of the Management Agreement are substantially similar to those of the Prior Management Agreement, except for the name of the investment adviser and the date of effectiveness.

        For the year ended December 31, 2016, in accordance with the Prior Management Agreement, we accrued, and the investment adviser earned, management fees of $2 million. Following the approval by our stockholders of the Management Agreement in May 2017, such accrued management fees were paid.

        The Company has entered into indemnification agreements with each of its current directors and officers and intends to enter into indemnification agreements with each of its future directors and officers. The indemnification agreements provide these directors, officers and other persons the

20

---

maximum indemnification permitted under Maryland law and the Investment Company Act. The agreements provide, among other things, for the advancement of expenses and indemnification for liabilities that such person may incur by reason of his or her status as a present or former director or officer in any action or proceeding arising out of the performance by such person as a present or former director or officer.

Compensation and Corporate Governance Committee Interlocks and Insider Participation

        No member of the Compensation and Corporate Governance Committee during fiscal year 2016 served as an officer, former officer or employee of ours or had a relationship disclosable under Item 404 of Regulation S-K. Further, during 2016, none of our executive officers served as:

•

a member of the compensation committee (or equivalent) of any other entity, one of whose executive officers served as one of our directors or was an immediate family member of a director, or served on our Compensation and Corporate Governance Committee; or



•

a director of any other entity, one of whose executive officers or their immediate family member served on our Compensation and Corporate Governance Committee.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        The Company has procedures in place for the review, approval and monitoring of transactions involving the Company and certain persons related to it. As a BDC, the Company is restricted by the Investment Company Act from participating in transactions with any persons affiliated with it, including its officers and directors, and any other person controlling or under common control with the Company, subject to certain exceptions. The Board has also adopted a policy regarding the approval of any "related person transaction," which is any transaction or series of transactions in which the Company or any of its subsidiaries is or are to be a participant, the amount involved exceeds $120,000, and a "related person" (as defined under Commission rules) has a direct or indirect material interest. Under the policy, a related person would need to promptly disclose to the Company's Secretary any related person transaction and all material facts about the transaction. The Company's Secretary would then assess and promptly communicate that information to the Compensation and Corporate Governance Committee of the Board. Based on its consideration of all of the relevant facts and circumstances, this committee will decide whether or not to approve such transaction and will generally approve only those transactions that do not create a conflict of interest. If the Company becomes aware of an existing related person transaction that has not been pre-approved under this policy, the transaction will be referred to this committee, which will evaluate all options available, including ratification, revision or termination of such transaction. The Company's policy requires any director who may be interested in a related person transaction to recuse himself or herself from any consideration of such related person transaction.

        The Company's Code of Ethics, which was reviewed and approved by the Board and provided to all of the Company's directors and officers, ACSF Management, IHAM, the persons who provided services to the Company pursuant to ACSF Management's previous administrative services agreement, and the persons who provide services to the Company pursuant to the IHAM Administration Agreement (as defined below) and requires that all such persons avoid any situations or relationships that involve actual or potential conflicts of interest, or perceived conflicts of interest, between an individual's personal interests and the interests of the Company. Pursuant to the Company's Code of Ethics, each of these persons must disclose any conflicts of interest, or actions or relationships that might give rise to a conflict, to their supervisor or the Company's Secretary. If a conflict is determined to exist, the person must disengage from the conflict situation or terminate his provision of services to the Company. The Company's chief executive officer, chief financial officer, principal accounting officer and certain other persons who may be designated by the Board or its Audit and Compliance Committee, whom we collectively refer to as our financial executives, must consult with the Company's Secretary with respect to any proposed actions or arrangements that are not clearly consistent with the Code of Ethics. In the event that a financial executive wishes to engage in a proposed action or arrangement that is not consistent with the Code of Ethics, the financial executive must obtain a waiver of the relevant provisions of the Code of Ethics in advance from the Company's Audit and Compliance Committee. The Company intends to post amendments to or waivers from the Code of Ethics (to the extent applicable to the Company's financial executives) on the Company's web site www.ACSF.com.

        The Company previously entered into the Prior Management Agreement with ACSF Management, an entity in which certain directors and officers of the Company and members of the investment committee of the investment adviser may have had indirect ownership and pecuniary interests. The Prior Management Agreement automatically terminated in accordance with its terms as a result of its deemed "assignment" under the Investment Company Act following the acquisition on January 3, 2017, of American Capital Ltd. ("ACAS") by Ares Capital (the "Acquisition"). ACSF Management, our previous investment adviser, was an indirect wholly owned subsidiary of American Capital Asset Management, LLC ("ACAM"), a wholly owned portfolio company of ACAS. In connection with the Acquisition, ACAM merged with and into IHAM, a wholly owned portfolio company of Ares Capital, with IHAM being the surviving entity in such merger.

22

---

        The Company's wholly owned consolidated special purpose financing vehicle, ACSF Funding I, LLC ("ACSF Funding I"), previously entered into an investment advisory agreement with ACSF Management to manage its assets. No additional compensation was payable to ACSF Management under such agreement, which was terminated on January 3, 2017. On January 3, 2017, ACSF Funding I entered into a new investment advisory agreement with IHAM to manage its assets. No additional compensation is payable to IHAM under such agreement.

        The Company has entered into the Management Agreement with IHAM, an entity in which certain directors and officers of the Company and members of the investment committee of IHAM may have indirect ownership and pecuniary interests. Certain directors and officers of the Company and members of the investment committee of IHAM also serve as officers or principals of other investment managers affiliated with Ares Management that currently, and may in the future, manage investment funds with investment objectives similar to the Company's investment objective. In addition, certain of the Company's officers and directors and the members of the investment committee of IHAM serve or may serve as officers, directors or principals of entities that operate in the same or related line of business as the Company or of investment funds managed by the Company's affiliates, including Ares Management. Accordingly, the Company may not be made aware of and/or be given the opportunity to participate in certain investments made by investment funds managed by advisers affiliated with Ares Management. However, IHAM intends to allocate investment opportunities in a fair and equitable manner in accordance with its investment allocation policy. The Management Agreement contains substantially the same terms as the Prior Management Agreement, with the exception of its effective and termination dates and other immaterial differences.

        Under both the Management Agreement and the Prior Management Agreement, the Company pays a management fee calculated at an annual rate of 0.8% of the Company's total assets (excluding cash and cash equivalents and net unrealized appreciation or depreciation). The management fee is payable quarterly in arrears. The management fee is calculated based on the Company's total assets (excluding cash and cash equivalents and net unrealized appreciation or depreciation, each as determined under U.S. generally accepted accounting principles) at the end of the most recently completed fiscal quarter. For the year ended December 31, 2016, in accordance with the Prior Management Agreement, we accrued, and ACSF Management earned, management fees of $2 million. Following the approval by our stockholders of the Management Agreement in May 2017, such accrued management fees were paid.

        Beginning in the first quarter of 2017, our Manager voluntarily agreed to be responsible for certain of our 2017 quarterly other operating expenses in excess of a certain percentage of our consolidated net assets, less net unrealized appreciation or depreciation, each as defined under GAAP (individually, for each such quarter, a "Voluntary Expense Cap" and collectively, the "Voluntary Expense Caps"). With respect to the first and second quarters of 2017, the Voluntary Expense Cap was calculated based on an annual rate of 0.75% of our consolidated net assets less net unrealized appreciation or depreciation as of March 31, 2017, and an annual rate of 1.00% of our consolidated net assets less net unrealized appreciation or depreciation as of June 30, 2017, respectively. With respect to the third and fourth quarters of 2017, the Voluntary Expense Cap will be based on an annual rate of 1.00% of our consolidated net assets less net unrealized appreciation or depreciation as of September 30, 2017, and an annual rate of 1.25% of our consolidated net assets less unrealized appreciation or depreciation as of December 31, 2017, respectively, provided that the Management Agreement remains effective as of the date we file our Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as applicable, for such quarter period. The Voluntary Expense Caps are expected to expire pursuant to their terms on December 31, 2017.

        The Company relies on IHAM to administer the Company's business activities and day-to-day operations, subject to the supervision and oversight of the Board. IHAM has entered into an administrative services agreement with Ares Operations (the "IHAM Administration Agreement"),

23

---

pursuant to which Ares Operations provides IHAM with, among other things, office facilities, equipment, clerical, bookkeeping and record keeping services, services relating to the marketing and sale of interests in vehicles managed by IHAM, services of, and oversight of, custodians, depositaries, accountants, attorneys, underwriters and such other persons in any other capacity deemed to be necessary, which allows IHAM to fulfill all of its responsibilities under the Management Agreement. However, the Company is not a party to, or a third-party beneficiary under, the IHAM Administration Agreement. In addition, neither the IHAM Administration Agreement nor the Management Agreement requires IHAM or Ares Operations to dedicate specific personnel to the Company's operations nor a specific amount of time to the Company's business.

PROPOSAL 2: RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        The Audit and Compliance Committee and the Board, including a majority of the independent directors, have selected Ernst & Young LLP as the independent registered public accounting firm for the Company for the year ending December 31, 2017 and are submitting the selection of Ernst & Young LLP to the stockholders for ratification.

        If the stockholders fail to ratify the selection, the Audit and Compliance Committee and the Board will reconsider whether or not to continue to retain Ernst & Young LLP. Even if the selection is ratified, the Audit and Compliance Committee and the Board may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

        Ernst & Young LLP has advised the Company that neither the firm nor any present member or associate of it has any financial interest, direct or indirect, in the Company or its affiliates.

        The Company expects that a representative of Ernst & Young LLP will be present at the Annual Meeting, will have an opportunity to make a statement if he or she so chooses and will be available to answer questions.

Principal Accountant Fees and Services

        Ernst & Young LLP has served as our independent public accountant since our IPO. The following are aggregate fees billed to the Company by Ernst & Young LLP during each of the last two fiscal years:

Audit Fees

        Audit fees relate to fees and expenses billed by Ernst & Young LLP for the annual audit, including the audit of our financial statements and review of our quarterly financial statements.

Audit-Related Fees

        Audit-related fees are fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under "Audit Fees."

Tax Fees

        Tax fees relate to fees billed for professional services for tax compliance.

All Other Fees

        All other fees consist of fees for products and services other than the services reported above.

25

---

Pre-Approval Policy

        All services rendered by Ernst & Young LLP were permissible under applicable laws and regulations, and were pre-approved by the Audit and Compliance Committee for 2016 in accordance with its pre-approval policy. The Audit and Compliance Committee has established a policy regarding the pre-approval of all audit and permissible non-audit services provided by our independent public accountant. The policy requires the Audit and Compliance Committee to approve each audit or non-audit engagement or accounting project involving the independent public accountant, and the related fees, prior to commencement of the engagement or project to make certain that the provision of such services does not impair the firm's independence. The committee may delegate its pre-approval authority to one or more of its members, and such member(s) are required to report any pre-approval decisions to the Audit and Compliance Committee at its next meeting. The Audit and Compliance Committee has delegated authority to its Chair to pre-approve the engagement and related fees of the independent public accountant for any additional audit or permissible non-audit services. In addition, pursuant to the policy, pre-approval is not required for additional non-audit services if such services result in a de minimis amount of less than 5% of the total annual fees paid by us to the independent public accountant during the fiscal year in which the non-audit services are provided, were not recognized by us at the time of engagement to be non-audit services and are reported to the Audit and Compliance Committee promptly thereafter and approved prior to the completion of the annual audit.

        Notwithstanding anything to the contrary set forth in any of the Company's previous filings under the Securities Act of 1933, as amended (the "Securities Act"), or the Exchange Act that might incorporate future filings, including this proxy statement, in whole or in part, the following Report of the Audit and Compliance Committee shall not be deemed to be "soliciting material" or to be "filed" with the Commission, nor shall such information be incorporated by reference into any such filings under the Securities Act or the Exchange Act.

REPORT OF THE AUDIT AND COMPLIANCE COMMITTEE

        The Board of Directors has appointed an Audit and Compliance Committee presently composed of three directors, Ms. Caldwell and Messrs. Crawford and Harvey. Each of the directors is independent as defined in the NASDAQ rules. The Board of Directors has determined that Mr. Harvey is an "audit committee financial expert" (as defined in Item 407 of Regulation S-K under the Securities Act).

        The Audit and Compliance Committee's responsibility is one of oversight as set forth in its charter, which is available in the Investor Relations section of our web site at www.ACSF.com. It is not the duty of the Audit and Compliance Committee to prepare our financial statements, to plan or conduct audits or to determine that our financial statements are complete and accurate and are in accordance with U.S. generally accepted accounting principles. Our management is responsible for preparing our financial statements and for maintaining internal controls. The independent auditors are responsible for auditing the financial statements and for expressing an opinion as to whether those audited financial statements fairly present our financial position, results of operations, changes in net assets and cash flows in conformity with U.S. generally accepted accounting principles.

        The Audit and Compliance Committee has reviewed and discussed our audited consolidated financial statements with management and with Ernst & Young LLP, our independent auditors for 2016.

        The Audit and Compliance Committee has discussed with Ernst & Young LLP the matters required to be discussed by Auditing Standard No. 16 (which superseded Auditing Standard No. 61, as amended), as adopted by the Public Company Accounting Oversight Board.

        The Audit and Compliance Committee has received from Ernst & Young LLP the written statements required by Public Company Accounting Oversight Board Rule No. 3526, "Communications with Audit Committees Concerning Independence," and has discussed Ernst & Young LLP's independence with Ernst & Young LLP, and has considered the compatibility of non-audit services with the auditor's independence.

        Based on the review and discussions referred to above, the Audit and Compliance Committee recommended to the Board of Directors that the audited consolidated financial statements for the year ended December 31, 2016 be included in our Annual Report on Form 10-K for the year ended December 31, 2016, for filing with the Securities and Exchange Commission.

        The Audit and Compliance Committee has approved the appointment of Ernst & Young LLP to serve as our independent public accountants for the year ending December 31, 2017 and has directed that the appointment of Ernst & Young LLP be submitted to our stockholders for ratification.

Use of Report of the Audit and Compliance Committee

        In accordance with and to the extent permitted by applicable law or regulation, the information contained in the foregoing Report of the Audit and Compliance Committee is not "soliciting material" and is not to be incorporated by reference into any future filing under the Securities Act or the Exchange Act.

        The affirmative vote of holders of at least a majority of the votes cast by holders of our common stock at the Annual Meeting is required for ratification of the selection of Ernst & Young LLP as the

27

---

Company's independent registered public accounting firm for the fiscal year ending December 31, 2017. Abstentions will have no effect on the outcome of the proposal. The persons named in the accompanying proxy intend to vote proxies received by them for this proposal unless a choice "Against" or "abstain" is specified.

        The Board, based on the approval and recommendation of the Audit and Compliance Committee, recommends voting FOR ratification of the selection of Ernst & Young LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2017.

FINANCIAL STATEMENTS AVAILABLE

        A copy of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2016 containing audited financial statements accompanies this proxy statement. Such financial statements are hereby incorporated herein by reference.

        Along with this proxy statement, the Company will provide to each stockholder a copy (without exhibits, unless otherwise requested) of its Annual Report on Form 10-K required to be filed with the Commission for the year ended December 31, 2016. Copies of these documents may also be accessed electronically by means of the Commission's home page on the Internet at http://www.sec.gov. Other than the financial statements incorporated by reference above, the Annual Report on Form 10-K is not part of the proxy solicitation materials.

HOUSEHOLDING OF PROXY MATERIALS

        The Commission has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement and annual report addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

        This year a number of brokers with account holders who are the Company's stockholders will be "householding" the Company's proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. If you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. We will promptly deliver a separate copy of these documents to you upon written or oral request to the Company's Investor Relations Department at American Capital Senior Floating, Ltd., 245 Park Avenue, 42nd Floor, New York, New York 10167 or 888-818-5298. If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate proxy statement and annual report, please notify your broker. Stockholders who currently receive multiple copies of the proxy statement and annual report at their addresses and would like to request "householding" of their communications should contact their brokers.
