Investment Objectives and Practices [Text Block]

The Company is a Delaware corporation formed on October 12, 2020 and is an externally managed, closed-end, non-diversified management investment company. We have elected to be regulated as a BDC under the Investment Company Act of 1940, as amended (the “1940 Act”). Our investment objective is to achieve high risk-adjusted returns produced primarily from current income generated by investing primarily in senior secured corporate debt instruments. We seek to achieve our investment objective through investments in privately-originated, performing senior secured debt primarily in North America-based companies with target enterprise values between $100 million and $1.5 billion. Performing debt is debt that at the time of investment is not defaulted or, in the view of the

Advisor, distressed. The Company targets positions in first lien, second lien and unitranche debt, with a preference for floating-rate debt, which the Advisor believes provides flexibility to adapt to changing market conditions. The Company may invest in securities of any maturity and credit quality. Our investment activities will benefit from what we believe are the competitive advantages of our Advisor, including its diverse in-house skills, proprietary deal flow, and consistent and rigorous investment process focused on established, middle-market companies.
