Golub Capital BDC GBDC · USD

We are an externally managed, closed-end, non-diversified management investment company that has elected to be regulated as a business development company under the Investment Company Act of 1940, as amended, or the 1940 Act. In addition, for U.S. federal income tax purposes, we have elected to be treated as a regulated investment company, or RIC, under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code. We were formed in November 2009 to continue and expand the business of our predecessor, Golub Capital Master Funding LLC, which commenced operations in July 2007. We make investments primarily in one stop loans (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. GC Advisors structures these one stop loans as senior secured loans, and we obtain security interests in the assets of the portfolio company that serve as collateral in support of the repayment of these loans. This collateral often takes the form of first-priority liens on the assets of the portfolio company. In many cases, we are the sole lender or we, together with our affiliates, are the sole lenders of one stop loans, which can afford us additional influence over the borrower in terms of monitoring and, if necessary, remediating any underperformance.
