Note 1. Organization

Golub Capital BDC, Inc. (“GBDC” and, collectively with its consolidated subsidiaries, the “Company”) is an externally managed, closed-end, non-diversified management investment company. GBDC has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). In addition, for U.S. federal income tax purposes, GBDC has elected to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).

The Company’s investment strategy is to invest primarily in one stop (a loan that combines characteristics of traditional first lien senior secured loans and second lien or subordinated loans and that are often referred to by other middle-market lenders as unitranche loans) and other senior secured loans of U.S. middle-market companies that are, in most cases, sponsored by private equity firms. The Company also selectively invests in second lien and subordinated (a loan that ranks senior only to a borrower’s equity securities and ranks junior to all of such borrower’s other indebtedness in priority of payment) loans of, and warrants and minority equity securities in, U.S. middle-market companies. The Company has entered into the Third Amended and Restated Investment Advisory Agreement dated as of September 16, 2019 (the “Investment Advisory Agreement”) with GC Advisors LLC (the “Investment Adviser”), under which the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, the Company. Under an administration agreement (the “Administration Agreement”) the Company is provided with certain services by an administrator (the “Administrator”), which is currently Golub Capital LLC.

On September 16, 2019, the Company completed its acquisition of Golub Capital Investment Corporation (“GCIC”), a Maryland corporation, pursuant to that certain Agreement and Plan of Merger (as amended, the “Merger Agreement”), dated as of November 27, 2018, by and among the Company, GCIC, Fifth Ave Subsidiary Inc., a Maryland corporation and wholly owned subsidiary of the Company, the Investment Adviser, and, for certain limited purposes, the Administrator.

On January 1, 2020 the Company entered into a purchase agreement (the “Purchase Agreement”) with RGA

Reinsurance Company (“RGA”), Aurora National Life Assurance Company (“Aurora”), Senior Loan Fund

(“SLF”), and GCIC Senior Loan Fund LLC (“GCIC SLF”). Pursuant to the Purchase Agreement, RGA and Aurora

(together the “Transferors”) agreed to sell their limited liability company (“LLC”) equity interests in SLF and GCIC

SLF, respectively, to the Company, effective as of January 1, 2020. As a result of the Purchase Agreement, on

January 1, 2020, SLF and GCIC SLF became wholly-owned subsidiaries of the Company and the capital

commitments of the Transferors to SLF and GCIC SLF were terminated.
