Investment Objectives and Practices [Text Block]

INVESTMENT OBJECTIVE

We seek to achieve our investment objective by investing primarily in entities that in turn own a pool of senior secured loans made to companies whose debt is rated below investment grade or, in limited circumstances, unrated, which we collectively refer to as “Senior Secured Loans.” We have invested primarily in the equity and junior debt tranches of a type of pools of Senior Secured Loans known as Collateralized Loan Obligations, or “CLOs.” Based on certain diversification, liquidity and general market considerations, we may also invest opportunistically in Senior Secured Loans directly (either in the primary or secondary markets).

Risk Factors [Table Text Block]

Investment Risks

Our investments are subject to a variety of risks. Those risks include the following:

Market Risk

Market risk represents the potential loss that can be caused by a change in the fair value of the financial instrument.

Credit Risk

Credit risk represents the risk that we would incur if the counterparties failed to perform pursuant to the terms of their agreements with us.

Credit Spread Risk

Credit spread risk represents the risk that with higher interest rates comes a higher risk of defaults.

Liquidity Risk

Liquidity risk represents the possibility that we may not be able to rapidly adjust the size of our investment positions in times of high volatility and financial stress at a reasonable price.

Interest Rate Risk

Interest rate risk represents a change in interest rates, which could result in an adverse change in the fair value of an interest-bearing financial instrument.

Prepayment Risk

Many of our debt investments allow for prepayment of principal without penalty. Downward changes in interest rates may cause prepayments to occur at a faster than expected rate, thereby effectively shortening the maturity of the security and making us less likely to fully earn all of the expected income of that security and reinvesting in a lower yielding instrument.

Downgrade Risk

Downgrade risk results when rating agencies lower their rating on a bond which are usually accompanied by bond price declines.

Default Risk

Default risk is the risk that a borrower will be unable to make the required payments on their debt obligation.

Structured Credit Related Risk

CLO investments may be riskier and less transparent to us than direct investments in underlying companies. CLOs typically will have no significant assets other than their underlying senior secured loans. Therefore, payments on CLO investments are and will be payable solely from the cash flows from such senior secured loans.

Market Disruption and Geopolitical Risk

Geopolitical and other events, such as war (including the Israel-Hamas war and Russia's military invasion of Ukraine), terrorist attacks, public health crises and natural or environmental disasters, may disrupt securities markets and

adversely affect global economies and markets. Those events, as well as other changes in non-U.S. and U.S. economic and political conditions, could adversely affect the value of the Company’s investments.

Economic Recessions Risk

Economic recessions or downturns could impair our portfolio investments and adversely affect our operating results.

Capital Stock, Long-Term Debt, and Other Securities [Abstract]

Long Term Debt [Table Text Block]

Note 11. Revolving Credit Facility

On September 6, 2022, we entered into a secured revolving credit facility (the “Facility”). The aggregate commitment of the Facility was $40,000,000 and is collateralized by our CLO investments. The Facility matures on September 28, 2028 and generally bears interest at the current 1 month SOFR Rate plus 3.25% subject to a SOFR floor of 0.25%. Additionally, the lender charges a fee on the unused portion of the credit facility equal to 0.375% per annum on the difference between the commitment amount and the average daily funded amount of the Facility. On March 31, 2023, the commitment of the Facility was increased to $75,000,000. On March 28, 2024, the second amendment was signed extending the maturity of the Facility from March 6, 2027 to September 28, 2028.

As part of the Facility, we are required to maintain an interest reserve account that will contain the greater of $250,000 or the product of the weighted average daily advances outstanding during the immediately prior calendar month, multiplied by the interest rate and 90/360. Such amounts are classified as Restricted cash on our Statement of Assets and Liabilities. As of June 30, 2026, we held $250,000 in the interest reserve account.

The agreement governing our Facility requires us to comply with certain financial and operational covenants. These covenants include restrictions on the level of indebtedness that we are permitted to incur in relation to the value of our assets and a minimum total net asset level that we are required to maintain.

Note 4. Capital

The Company offers its shares of common stock with varying up-front sales loads and has elected to designate each level of sales load as a “class” solely as a means of identifying those differing sales loads and the different channels through which shares are sold. Shares available to the general public are charged selling commissions and dealer manager fees and are referred to as “Class R Shares”. Shares available to accounts managed by registered investment advisers are charged dealer manager fees but no selling commissions and are referred to as “Class RIA Shares”. Shares available for purchase through (1) fee-based programs, also known as wrap accounts, of investment dealers, (2) participating broker-dealers that have alternative fee arrangements with their clients, (3) certain registered investment advisors or (4) bank trust departments or any other

organization or person authorized to act in a fiduciary capacity for its clients or customers are charged no selling commissions or dealer manager fees and are referred to as “Class I Shares.” Although the Company uses “Class” designations to indicate its differing sales load structures, the Company does not operate as a multi-class fund.

Share Repurchase Program

The Company conducts quarterly tender offers pursuant to its share repurchase program. The Company’s Board considers the following factors, among others, in making its determination regarding whether to cause us to offer to repurchase shares and under what terms:

•the effect of such repurchases on our qualification as a RIC (including the consequences of any necessary asset sales);

•the liquidity of the Company’s assets (including fees and costs associated with disposing of assets);

•the Company’s investment plans and working capital requirements;

•the relative economies of scale with respect to the Company’s size;

•the Company’s history in repurchasing shares or portions thereof; and

•the condition of the securities markets.

The Company limits the number of shares to be repurchased in any calendar quarter to up to 2.5% of the number of shares outstanding at the close of business on the last day of the prior fiscal year. At the discretion of the Company’s Board, the Company may use cash on hand, and cash from the sale of investments as of the end of the applicable period to repurchase shares. The Company will offer to repurchase such shares at a price equal to the net asset value per share of our common stock specified in the tender offer. The Company’s Board may suspend or terminate the share repurchase program at any time. The first such tender offer commenced in May 2015.

The following table sets forth the number of common shares that were repurchased by the Company in each tender offer:
