Voting Securities

You may cast one vote for each share of common stock of the Company that you owned as of the Record Date for each matter submitted for a vote at the Annual Meeting. Each share of the Company’s common stock has equal voting rights with all other shares of the Company’s common stock, which is the only class of voting securities outstanding of the Company. As of the close of business on the April 12, 202111, 2022 Record Date, BCPL had 1,665,1291,861,143 shares of common stock outstanding.

Quorum Required

For the Company to conduct business at the Annual Meeting, a quorum of stockholders must be present at the Annual Meeting. The presence at the Annual Meeting, in person (virtually) or by proxy, of the holders entitled to cast a majority of the shares of the Company’s common stock outstanding on the Record Date will constitute a quorum. Abstentions will be treated as shares present for quorum purposes.

Shares for which brokers have not received voting instructions from the beneficial owner of the shares and do not have discretionary authority to vote on certain proposals (which are considered “broker non-votes” with respect to such proposals) will be treated as shares present for quorum purposes.

The Chairman of the Annual Meeting for the Company shall have the power to adjourn the Annual Meeting, whether or not a quorum is present, from time to time for any reason and without notice other than announcement at the Annual Meeting.

Submitting Voting Instructions for Shares Held Through a Broker, Bank, Trustee or Nominee

If you hold shares of the Company’s common stock through a broker, bank, trustee or nominee, you must direct your intermediary regarding how you would like your shares voted by following the voting instructions you receive from your broker, bank, trustee or nominee. If you hold shares of the Company’s common stock through a broker, bank, trustee or nominee and want to participate in the virtual Annual Meeting, you must follow the instructions you receive from your broker, bank, trustee or nominee. Please instruct your broker, bank, trustee or nominee regarding how you would like your shares voted so your vote can be counted.

Discretionary Voting

Brokers, banks, trustees and nominees have discretionary authority to vote on “routine” matters, but not on “non-routine” matters. The “routine” matter being considered by the Company at this Annual Meeting is the ratification of the appointment of the Company’s independent registered public accounting firm, and the “non-routine”“non-routine” matters being considered by the Company at this Annual Meeting is the election of directors. If you hold

Please note that to be sure your vote is counted on the Company’s proposal to elect directors, you should instruct your broker, bank, trustee or nominee how to vote your shares by following the voting instructions provided by your broker, bank, trustee or nominee. If you do not provide voting instructions, votes may not be cast on your behalf with respect to such proposals.

Authorizing a Proxy for Shares Held in Your Name

If you are a record holder of shares of the Company’s common stock, you may authorize a proxy to vote on your behalf by following the instructions provided on the Notice of Internet Availability of Proxy Materials. Authorizing your proxy will not limit your right to participate in the virtual Annual Meeting and vote your shares online. A properly completed and submitted proxy will be voted in accordance with your instructions unless you subsequently revoke your instructions. If you authorize a proxy without indicating your voting instructions, the proxyholder will vote your shares according to the Board’s recommendations. Internet and telephone voting procedures are designed to authenticate the stockholder’s identity and to allow stockholders to vote their shares and confirm that their instructions have been properly recorded. Your Internet or telephone vote authorizes the named proxies to vote your shares in the same manner as if you had marked, signed and returned a proxy card.

Receipt of Multiple Proxy Cards

Some of the Company’s stockholders hold their shares in more than one account and may receive a separate Notice of Internet Availability of Proxy Materials for each of those accounts. To ensure that all of your shares are represented at the Annual Meeting, we recommend that you vote by following the instructions in each Notice of Internet Availability of Proxy Materials you receive.

Revoking Your Proxy

If you are a stockholder of record of BCPL, you can revoke your proxy at any time before it is exercised by: (i) delivering a written revocation notice that is received prior to the Annual Meeting to BC Partners Lending Corporation, as applicable, at 650 Madison Avenue, New York, New York 10022, Attention: Secretary; (ii) submitting a later-dated proxy that we receive before the conclusion of voting at the Annual Meeting; or (iii) participating in the virtual Annual Meeting and voting online. If you hold shares of the Company’s common stock through a broker, bank, trustee or nominee, you must follow the instructions you receive from them in order to revoke your voting instructions. Participating in the virtual Annual Meeting does not revoke your proxy unless you also vote online at the Annual Meeting.

Votes Required

Election of directors. The affirmative vote of a plurality of all the votes cast in the election of directors at the Annual Meeting is required to elect the director nominee of thatthe Company (i.e., the candidate receiving the most “for” votes will win the election). Stockholders may not cumulate their votes. Abstentions, votes to “withhold authority” and broker non-votes will have no effect on this proposal, although they will be considered present for the purpose of determining the presence of a quorum.

Ratification of independent registered public accounting firm. The affirmative vote of a majority of the votes cast at the Annual Meeting is required to ratify the appointment of Deloitte to serve as the Company’s independent registered public accounting firm (i.e., the number of shares voted “for” the ratification of the appointment of Deloitte exceeds the number of votes “against” the ratification of the appointment of Deloitte). Abstentions and broker non-votes, if any, will not be included in determining the number of votes cast and, as a result, will have no effect on this proposal, although they will be considered present for the purpose of determining the presence of a quorum.

Information Regarding This Solicitation

The Company will bear the expenses of the solicitation of proxies. In addition to mail and e-mail, proxies may be solicited personally, via the Internet or by telephone or facsimile, by regular employees of the Company’s adviser or administrator, and its affiliates and/or a paid solicitor. No additional compensation will be paid to such regular employees for such services. The Company currently does not intend to engage a paid solicitor in connection with the Annual Meeting. If the Company retains a solicitor, it estimates that it will pay an aggregate of approximately $5,000$6,500 plus out-of-pocket expenses for such services and you could be contacted by telephone on behalf of the Company and be urged to vote. If the Company engages a solicitor, you could be contacted by telephone on behalf of the Company and be urged to vote. The solicitor will not attempt to influence how you vote your shares, but will only ask that you take the time to cast a vote. The Company will reimburse brokers and other persons holding the Company’s common stock in their names, or in the names of nominees, for their expenses for forwarding proxy materials to principals and beneficial owners and obtaining their proxies. The principal address of BCPL’s investment adviser, BC Partners Advisors L.P. (“BC Partners Advisors” and the “Adviser”) is 650 Madison Avenue, New York, New York 10022.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth, as of April 12, 2021,11, 2022, the beneficial ownership information of each current director, including the nominee for director, of the Company, as well as the Company’s executive officers, each person known to it to beneficially own 5% or more of the outstanding shares of its common stock, and the executive officers and directors as a group. Percentage of beneficial ownership is based on 1,665,1291,861,143 shares of BCPL’s common stock outstanding as of April 12, 2021.11, 2022.

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission (“SEC”) and includes voting or investment power with respect to the securities. Ownership information for those persons who beneficially own 5% or more of the shares of the Company’s common stock is based upon filings by such persons with the SEC and other information obtained from such persons, if available.

Unless otherwise indicated, the Company believes that each beneficial owner set forth in the table below has sole voting and investment power over the shares beneficially owned by such beneficial owner. The directors are divided into two groups — interested directors and independent directors. Each interested director is an “interested person” of the Company as defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended (the “1940 Act”). The address of all executive officers and directors is c/o BC Partners Lending Corporation, as applicable, at 650 Madison Avenue, New York, New York 10022.

The following table sets forth, as of April 12, 2021,11, 2022, the dollar range of our equity securities that is beneficially owned by the current directors of the Company.

The following table sets forth the dollar range of limited partnership interests in other private funds advised by and beneficially owned by any of our independent directors and his or her immediate family as of December 31, 2020.2021.

PROPOSAL 1 — ELECTION OF DIRECTORS

The business and affairs of the Company is managed under the oversight of its Board. BCPL’s Board currently consists of 54 members, of whom three are not “interested persons,” as defined in Section 2(a)(19) of the 1940 Act. The Board may modify the number of its members in accordance with the Company’s bylaws, except that no decrease in the number of directors will shorten the term of any incumbent director.

Under the charter of BCPL, directors are divided into three classes. At each annual meeting of stockholders of the Company, the successors to the directors whose terms expire at such meeting will be elected to serve until the annual meeting of stockholders held in the third year following the year of his or her election and until his or her successor has been duly elected and qualifies or any director’s earlier resignation, removal from office, death or incapacity.

Mr. WarshauerDuka has been nominated for re-election to the Board of BCPL, for a three-year term expiring at the 20242025 annual meeting of stockholders of the Company. Mr. WarshauerDuka was elected to BCPL’s Board for a term commencing on April 9, 2018.

No person being nominated by the Company as a director is being proposed for election pursuant to any agreement or understanding between any such person and that Company.

Required Vote

A plurality of all of the votes cast at the Annual Meeting duly called and at which a quorum is present is necessary to elect a director. Any stockholder of BCPL as of the Record Date can vote for or withhold authority on the director nominee. Abstentions, votes to “withhold authority” and broker non-votes will have no effect on the election of the director nominee, although they will be considered present for the purpose of determining the presence of a quorum. 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 nominee named above. If the nominee should be unable to serve or for good cause will not serve as a director, it is intended that the proxy will be voted for the election of such person nominated by the Board as a replacement. The Board does not have any reason to believe that the director nominee named will be unable or unwilling to serve.

The Company’s Board unanimously recommends a vote “FOR” the director nominee described in this proxy statement.

Director and Executive Officer Information

Directors

Information regarding the Company’s nominee for election as a director at the Annual Meeting and the Company’s continuing directors is set forth below. We have divided the directors into two groups — independent directors and interested directors. Each interested director is an “interested person” of suchthe Company, as defined in Section 2(a)(19) of the 1940 Act.

Independent Directors

Alexander Duka. Mr. Duka is the chairman of the Compensation Committee of the Board. Mr. Duka also serves on the Audit Committee and Nominating and Corporate Governance Committee of the Board. Mr. Duka was the Executive Vice President of Corporate Development for Acceleration Bay LLC, a patent investment and technology acceleration business headquartered in San Mateo, CA until December 2019, and remains a senior

Committee of Giuliani Capital Advisors LLC, and its predecessor firm, Ernst & Young Corporate Finance LLC. He has also held the position of CEO and President of a branded retail business with over 500 locations and 5,000 employees, been the CEO of an international business services and manufacturing company with operations in 16 countries, and served as President and a member of the Board of Directors of a publicly traded technology company. He is a former member of the board of directors of the American Bankruptcy Institute and currently serves on several corporate and charitable boards of directors. Mr. Warshauer received his M.B.A. from New York University and his B.S.B.A. from Bucknell University.

Through his broad experience as an officer and director of several companies, in addition to skills acquired with firms engaged in investment banking and financial services, Mr. Warshauer brings extensive business and

other things, an improperly constituted Board. The Company has appointed a lead independent director who acts as the presiding independent director at meetings of the “Non-Management Directors” (which will include the independent directors and other directors who are not officers of the Company even though they may have another relationship with the Company or its management that prevents them from being independent directors). Currently, Mr. Duka serves as the designated lead independent director of the Board.

Presently, Mr. Goldthorpe serves as both Chairman of the Board and President and Chief Executive Officer of the Company. The Board believes that while independent oversight of management is an important component of an effective board of directors, the most effective leadership structure for the Company at the present time is for Mr. Goldthorpe to serve as the principal executive officer of the Company and also serve as Chairman of the Board. The independent directors believe that because Mr. Goldthorpe and his affiliates are ultimately responsible for the

The Board’s role in risk management is one of oversight. Oversight of investment activities extends to oversight of the risk management processes employed by the Adviser as part of its day-to-day management of investment activities. The Board reviews risk management processes at both regular and special Board meetings throughout the year, consulting with appropriate representatives of the Adviser as necessary and periodically requesting the production of risk management reports or presentations. The goal of the Board’s risk oversight function is to ensure that the risks associated with investment activities are accurately identified, thoroughly investigated and responsibly addressed. The Board’s oversight function cannot, however, eliminate all risks or ensure that particular events do not adversely affect the value of our investments. In particular, the Board may determine at any time to terminate the Advisory Agreement, without the payment of any penalty, upon 60 days’ written notice, and must evaluate the performance of the adviser, and re-authorize the advisory agreement on an annual basis. The Board also has primary responsibility for the valuation of the Company’s assets.

Under the Company’s Investment Advisory Agreement, fees payable to BC Partners Advisors equal (a) a base management fee of 1.00% (1.50% if an exchange listing occurs) of the value of BCPL’s average gross assets, excluding cash and cash equivalents but including assets purchased with borrowed amounts, at the end of the two most recently completed calendar quarters (b) an incentive fee based on BCPL’s performance.

The incentive fee consists of two parts, as follows:

(i) The first component, the income incentive fee, payable at the end of each quarter in arrears, equals 100% of the pre-incentive fee net investment income in excess of a 1.50% quarterly preferred return but less than 1.76% (1.818% if an exchange listing occurs), the upper level breakpoint, and 15% (17.50% if an exchange

Company necessary for the operations of the Company, which include providing to the Company office facilities, equipment and clerical, bookkeeping and record keeping services at such facilities and such other services as the Administrator, subject to review by the Board, shall from time to time deem to be necessary or useful to perform its obligations under the applicable Administration Agreement. The Administrator also provides to the Company portfolio collection functions for and is responsible for the financial and other records that the Company is required to maintain and prepares, prints and disseminates reports to the Company’s stockholders and reports and all other materials filed with the SEC.

For providing these services, facilities and personnel, the Company reimburses the Administrator the allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations

Pursuant to the Expense Support Agreement, “Available Operating Funds” means the sum of (i) the BCPL’s net investment company taxable income (including net short-term capital gains reduced by net long-term capital losses), (ii) BCPL’s net capital gains (including the excess of net long-term capital gains over net short-term capital losses), and (iii) dividends and other distributions paid to or otherwise earned by BCPL on account of investments in portfolio companies (to the extent such amounts listed in clause (iii) are not included under clauses (i) and (ii) above.)

Following any calendar quarter in which Available Operating Funds exceed the cumulative distributions paid to BCPL’s stockholders in such calendar quarter (the amount of such excess being hereinafter referred to as “Excess Operating funds”), BCPL shall pay such Excess Operating Funds, or a portion thereof in accordance

Review, Approval or Ratification of Transactions with Related Persons

The independent directors of the Company are required to review, approve or ratify any transactions with related persons (as such term is defined in Item 404 of Regulation S-K).

Material Conflicts of Interest

The Company’s executive officers, directors and certain members of the Adviser serve or may serve as officers, directors or principals of entities that operate in the same or a related line of business as we do or of investment funds managed by BC Partners or its affiliates. All of BCPL’s executive officers and independent directors serve as executive officers or independent directors of Portman Ridge Finance Corporation and Logan Ridge Finance Corporation. BCPL invests in secured debt of private middle-market companies, that pay interest at rates which are determined periodically on the basis of a floating base lending rate, made to private middle-market companies whose debt is rated below investment grade, similar to those that Portman Ridge Finance Corporation targetsand Logan Ridge Finance Corporation target for investment. BC Partners and its affiliates also manage and sub-advise private investment funds and accounts, and may manage other such funds and accounts in the future, which have investment mandates that are similar, in whole and in part, with the Company. Therefore, there may be certain investment opportunities that satisfy the investment criteria for the Company as well as private investment funds and accounts advised or sub-advised by BC Partners and its affiliates. Accordingly, BC Partners and its affiliates may have obligations to investors in those entities, the fulfillment of which might not be in the best interests of us or our stockholders. For example, the personnel of BC Partners may face conflicts of interest in the allocation of investment opportunities to the Company and such other funds and accounts.

The Company may invest alongside funds and accounts managed or sub-advised by its Adviser and its affiliates in certain circumstances where doing so is consistent with applicable law and SEC staff interpretations. For example, the Company may invest alongside such accounts consistent with guidance promulgated by the staff of the SEC permitting the Company and such other accounts to purchase interests in a single class of privately placed securities so long as certain conditions are met, including that the Adviser, acting on behalf of the Company and on behalf of other clients, negotiates no term other than price or terms related to price.

In addition, on October 23, 2018, the SEC issued an order granting BCPL’s application for exemptive relief to co-invest, subject to the satisfaction of certain conditions, in certain private placement transactions, with other funds managed by the Adviser or its affiliates, and any future funds that are advised by the Adviser or its affiliated investment advisers. Under the terms of the exemptive order, in order for the Company to participate in a co-investment transaction a “required majority” (as defined in Section 57(o) of the 1940 Act) of the Company’s independent directors must conclude that (i) the terms of the proposed transaction, including the consideration to be paid, are reasonable and fair to the Company and its stockholders and do not involve overreaching with respect of the Company or its stockholders on the part of any person concerned, and (ii) the proposed transaction is consistent with the interests of the Company’s stockholders and is consistent with the Company’s investment objectives and strategies and certain criteria established by the Board.

Although the Adviser will endeavor to allocate investment opportunities in a fair and equitable manner, the Company and its common stockholders could be adversely affected to the extent investment opportunities are allocated among the Company and other investment vehicles managed or sponsored by, or affiliated with, its executive officers, directors and members of the Adviser. The Company might not participate in each individual opportunity, but will, on an overall basis, be entitled to participate equitably with other entities managed by the Adviser and its affiliates. The Adviser is committed to treating all clients fairly and equitably such that none receive preferential treatment vis-à-vis the others over time, in a manner consistent with its fiduciary duty to each of them; however, in some instances, especially in instances of limited liquidity, the factors may not result in pro rata allocations or may result in situations where certain funds or accounts receive allocations where others do not.

in performing its duties and obligations under the Investment Advisory Agreement than it would if it were acting for its own account, and creates a potential conflict of interest.

Pursuant to the Administration Agreement, the Administrator furnishes the Company with the facilities, including its principal executive office, and administrative services necessary to conduct its day-to-day operations. The Company pays the Administrator its allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under the Administration Agreement, including, without limitation, a portion of the rent at market rates and compensation of suchthe Company’s chief financial officer, chief compliance officer, their respective staffs and other non-investment professionals that perform duties for the Company.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act, requires the Company’s directors and executive officers, and persons who own 10% or more of the Company’s common stock, to file reports of ownership and changes in ownership of its equity securities with the SEC. Based solely on a review of the copies of those forms filed with the SEC, or written representations that no such forms were required, except for a Form 4 filed late by BC Partners Co-Investment Holdings Limited due to an administrative oversight, the Company believes that its directors, executive officers and 10% or more beneficial owners complied with all Section 16(a) filing requirements during the fiscal year ended December 31, 2020.2021.

Corporate Governance

Corporate Governance Documents

The Code of Ethics, Audit Committee Charter, and Nominating and Corporate Governance Committee Charter for BCPL are available to any stockholder who requests them by writing to BC Partners Lending Corporation, 650 Madison Avenue, New York, New York 10022, Attention: Chief Compliance Officer.

Director Independence

In accordance with Section 2(a)(19) of the 1940 Act, the Board annually determines the independence of each director. No director is considered independent unless the Board has determined that he or she has no material relationship with the Company. The Company monitors the status of its directors and officers through the activities of the Company’s Nominating and Corporate Governance Committee and through a questionnaire to be completed by each director no less frequently than annually, with updates periodically if information provided in the most recent questionnaire has materially changed.

The Board has determined that each of the current directors is, and each director that served during fiscal year 2020,2021, was independent and has no relationship with the Company, except as a director and stockholder of the Company, with the exception of Messrs. Goldthorpe and Dell.Mr. Goldthorpe.

Evaluation

The Company’s directors perform an evaluation, no less frequently than annually, of the effectiveness of the Company’s Board and its committees. This evaluation includes Board and Board committee discussions.

650 Madison Avenue, New York, New York 10022, Attention: Secretary. Any communication to report potential issues regarding accounting, internal controls and other auditing matters will be directed to the Company’s Audit Committee. Appropriate personnel of the Company will review and sort through communications before forwarding them to the addressee(s).

Board Meetings and Committees

The Board met six (6)four (4) times during fiscal year 2020.2021. Each director attended at least 75% of the total number of meetings of the BCPL Board and committees during fiscal year 20202021 on which the director served that were held while the director was a member of the Board or such committee, as applicable. The Board’s standing committees are described below. Directors are encouraged, but not required, to attend each annual meeting of stockholders.

Audit Committee

The Company’s Audit Committee is responsible for selecting, engaging and discharging the Company’s independent accountants, reviewing the plans, scope and results of the audit engagement with its independent accountants, approving professional services provided by its independent accountants (including compensation thereof), reviewing the independence of its independent accountants and reviewing the adequacy of its internal control over financial reporting, as well as establishing guidelines and making recommendations to its Board regarding the valuation of its loans and investments.

Mr. Warshauer serves as the Chairman of the Audit Committee. The Company’s Audit Committee met five (5)four (4) times during fiscal year 2020.2021.

Nominating and Corporate Governance Committee

The Company’s Nominating and Corporate Governance Committee is responsible for determining criteria for service on the Board, identifying, researching and nominating directors for election by its stockholders, selecting nominees to fill vacancies on the Board or a committee of the Board, developing and recommending to the Board a set of corporate governance principles and overseeing the self-evaluation of the Board and its committees and evaluation of management.

The members of the Company’s Nominating and Corporate Governance Committee are Messrs. Duka, Grunebaum and Warshauer, each of whom is not an interested person of the Company as defined in the 1940 Act. Mr. Grunebaum serves as the Chairman of the BCPL Nominating and Corporate Governance Committees. The Nominating and Corporate Governance Committee met one (1) time during fiscal year 2020.2021.

The Company’s Nominating and Corporate Governance Committee considers qualified director nominees recommended by stockholders of the Company when such recommendations are submitted in accordance with either the Company’s bylaws and any other applicable law, rule or regulation regarding director nominations. Stockholders of the Company may submit candidates for nomination for the Company’s Board by writing to: Board of Directors, BC Partners Lending Corporation, 650 Madison Avenue, New York, New York 10022. When submitting a nomination for consideration, a stockholder must provide certain information about each person whom the stockholder proposes to nominate for election as a director, including: (i) the name, age, business address and residence address of the person; (ii) the principal occupation or employment of the person;

accompanied by the proposed nominee’s written consent to be named as a nominee and to serve as a director if elected. The Company has not received any recommendations from stockholders requesting consideration of a candidate for inclusion among the Nominating Committee’s slate of nominees in this proxy statement.

In evaluating director nominees, the Company’s Nominating and Corporate Governance Committee considers the following factors:

The Company’s Nominating and Corporate Governance Committee’s goal is to assemble a Board that brings it a variety of perspectives and skills derived from high quality business and professional experience.

Other than the foregoing, there are no stated minimum criteria for director nominees, although the Company’s Nominating and Corporate Governance Committee may also consider such other factors as it may deem are in the Company’s best interests and those of its stockholders. The Company’s Nominating and Corporate Governance Committee does not assign specific weights to particular criteria, and no particular criterion is necessarily applicable to all prospective nominees. The Company believes that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities. The Board do not have a specific diversity policy, but consider diversity of race, religion, national origin, gender, sexual orientation, disability, cultural background and professional experiences in evaluating candidates for Board membership.

The Company’s Nominating and Corporate Governance Committee identifies nominees by first evaluating the current members of the Board willing to continue in service. Current members of the Board with skills and experience that are relevant to the applicable business and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of the Board with that of obtaining a new perspective. If any member of the Board does not wish to continue in service or if the Nominating and Corporate Governance Committee of the Board decides not to re-nominate a member for re-election or the Board decides to add a new director to the Board, the Nominating and Corporate Governance Committee would identify the desired skills and experience of a new nominee in light of the criteria above. Current members of the Company’s Nominating and Corporate Governance Committee and Board would review and discuss, for nomination, the individuals meeting the criteria of the Nominating and Corporate Governance Committee. Research may also be performed to identify qualified individuals. The Nominating and Corporate Governance Committee of the Company has not, but may choose to, engage an independent consultant or other third party to identify or evaluate or assist in identifying potential nominees to the Company’s Board.

Director Compensation

The following table sets forth compensation of the Company’s directors for the fiscal year ended December 31, 2020:2021:

For fiscal year 2021,2022, the independent directors of BCPL will receive an annual retainer fee of $50,000. No compensation was paid to directors who were interested persons of BCPL as defined in the 1940 Act. The independent directors of BCPL review and determine their compensation.

PROPOSAL 2 — RATIFY THE APPOINTMENT OF DELOITTE AS THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE 20212022 FISCAL YEAR

Upon the recommendation of the Audit Committee of the Board, the Board has retained Deloitte as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2021,2022, subject to ratification by the Company’s stockholders.

On March 11, 2021, the Board of Directors (the “Board”) of the Company approved, based on the recommendation of the Company’s Audit Committee, the dismissal of KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm, effective immediately following the completion of its audit of the Company’s financial statements as of and for the year ended December 31, 2020 and the issuance of its report thereon on March 11, 2021.

The audit reports of KPMG on the Company’s consolidated financial statements as of December 31, 2020 and 2019, and for the fiscal year ended December 31, 2020 and for the period from October 2, 2019 (commencement of operations) to December 31, 2019 did not contain an adverse opinion or a disclaimer of opinion, and they were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the period from October 2, 2019 to December 31, 2019 and year ended December 31, 2020, and through March 11, 2021, there were no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) with KPMG on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures which, if not resolved to the satisfaction of KPMG, would have caused KPMG to make reference to the subject matter of the disagreements in connection with its audit report, and there were no “reportable events” as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

Based on the recommendation of the Audit Committee, the Board engaged Deloitte to serve as the Company’s independent registered public accounting firm, effective immediately upon the dismissal of KPMG as the Company’s independent registered public accounting firm.

During the period from October 2, 2019 to December 31, 2019 and the year ended December 31, 2020 and through March 11, 2021, neither the Company nor anyone on its behalf consulted with Deloitte regarding: (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a “reportable event” (as defined in Item 304(a)(1)(v) of Regulation S-K).

It is expected that a representative of Deloitte will participate in the virtual Annual Meeting and will have an opportunity to make a statement if he or she chooses and will be available to answer questions. After reviewing the Company’s audited financial statements for the fiscal year ended December 31, 2021, the Audit Committee of the Board recommended to the Board that such statements be included in the Company’s Annual Report on Form 10-K. A copy of the Audit Committee’s Report appears below.

Required Vote

For the Company, the affirmative vote of a majority of the votes cast at the Annual Meeting in person or by proxy is required to approve this proposal. Abstentions will not be included in determining the number of votes cast and, as a result, will have no effect on this proposal, although they will be considered present for the purpose of determining the presence of a quorum. Because brokers will have discretionary authority to vote for the ratification of the selection of the Company’s registered independent public accounting firm in the event that they do not receive voting instructions from the beneficial owner of shares of our common stock, there should not be any broker non-votes with respect to this proposal.

The Board unanimously recommends a vote “FOR” the proposal to ratify the appointment of Deloitte as the independent registered public accounting firm for the applicable Company for the fiscal year ending December 31, 2021.2022.

Review and Discussion with Independent Registered Public Accounting Firm

The Audit Committee has discussed with its independent registered public accounting firm, matters required to be discussed by Auditing Standard No. 1301, Communication with Audit Committees, as adopted by the Public Company Accounting Oversight Board and such other matters as the Audit Committee and its independent registered public accounting firm are required to discuss under auditing standards generally accepted in the United States. The Audit Committee received and reviewed the written disclosures and the letter from the independent registered public accounting firm required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees (as amended), as adopted by the Public Company Accounting Oversight Board, and has discussed with the firm its independence. The Audit Committee has also considered the compatibility of non-audit services with the firm’s independence.
