We are an internally managed closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act. We specialize in providing customized debt and equity financing to LMM companies in a broad range of investment segments located primarily in the United States. Our investment objective is to produce attractive risk-adjusted returns by generating current income from our debt investments and capital appreciation from our equity and equity related investments. Our investment strategy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in senior debt securities, secured by security interests in portfolio company assets. We also may invest in equity interests in our portfolio companies alongside our debt securities.

We focus on investing in companies with histories of generating revenues and positive cash flow, established market positions and proven management teams with strong operating discipline. We primarily target senior debt and equity investments in LMM companies. Our target companies typically have annual EBITDA between $3.0 million and $25.0 million, and our investments generally range in size from $5.0 million to $50.0 million.

We seek to fill the financing gap for LMM companies, which, historically, have had more limited access to financing from commercial banks and other traditional sources. The underserved nature of the LMM creates the opportunity for us to meet the financing needs of LMM companies while also negotiating favorable transaction terms and equity participations. Our ability to invest across a LMM company’s capital structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options. Providing customized financing solutions is important to LMM companies. We generally seek to partner directly with financial sponsors, entrepreneurs, management teams and business owners in making our investments. Our LMM debt investments typically include senior loans with a first lien on the assets of the portfolio company. Our LMM debt investments typically have a term of up to five years from the original investment date. We also often seek to invest in the equity securities of our LMM portfolio companies.

Because we are internally managed, we do not pay any external investment advisory fees, but instead directly incur the operating costs associated with employing investment and portfolio management professionals. We believe that our internally managed structure provides us with a beneficial operating expense structure when compared to other publicly traded and privately held investment firms that are externally managed, and our internally managed structure allows us the opportunity to leverage our non-interest operating expenses as we grow our investment portfolio. For the nine months ended December 31,

2024 and 2023, the ratio of our last twelve months ("LTM") operating expenses, excluding interest expense, as a percentage of our LTM average total assets was 1.61% and 1.84%, respectively.
