General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |
Investment Objectives and Practices [Text Block] |  |  |  |  |  |  |  |  |  |  |  | Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in first lien senior secured loans (including “unitranche” loans, which are loans that combine both senior and subordinated debt, generally in a first lien position) and second lien senior secured loans. In addition to senior secured loans, we also invest in subordinated loans (sometimes referred to as mezzanine debt), which in some cases includes an equity component and preferred equity. To a lesser extent, we also make common equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent debt investment). However, we may increase the size or change the nature of these investments.
Risk Factors [Table Text Block] |  |  |  |  |  |  |  |  |  |  |  | Risk Factors In addition to the other information set forth in this report, you should carefully consider the risk factors described below and in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and those set forth under the caption “Risk Factors” in our Form N-2, which could materially affect our business, financial condition and/or operating results. The risks described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and in the Form N-2 are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition and/or operating results. Our business is dependent on bank relationships and recent strain on the banking system may adversely impact us. The financial markets recently have encountered volatility associated with concerns about the balance sheets of banks, especially small and regional banks who may have significant losses associated with investments that make it difficult to fund demands to withdraw deposits and other liquidity needs. Although the federal government has assisted some of these banks and protected depositors, uncertainty remains. Our business is dependent on bank relationships and we are proactively monitoring the financial health of such bank relationships. Continued strain on the banking system may adversely impact our business, financial condition and results of operations.
Share Price [Table Text Block] |  |  |  |  |  |  |  |  |  |  |  | Price Range of Common Stock The following table sets forth, for the first three quarters of the year ending December 31, 2023 and each fiscal quarter for the fiscal years ended December 31, 2022 and 2021, the net asset value per share of our common stock, the range of high and low closing sales prices of our common stock, the closing sales price as a premium (discount) to net asset value and the dividends or distributions declared by us.

As of September 30, 2023, the applicable spread in effect was 1.75%. We are also required to pay a letter of credit fee of either 2.00% or 2.125% per annum on letters of credit issued, determined monthly based on the total amount of the borrowing base relative to the total commitments of the Revolving Credit Facility and other debt, if any, secured by the same collateral as the Revolving Credit Facility. Additionally, we are required to pay a commitment fee of 0.375% per annum on any unused portion of the Revolving Credit Facility. As of September 30, 2023, there was $1.4 billion outstanding under the Revolving Credit Facility and we were in compliance in all material respects with the terms of the Revolving Credit Facility.

The SMBC Funding Facility is secured by all of the assets held by ACJB. The end of the reinvestment period and the stated maturity date for the SMBC Funding Facility are May 28, 2024 and May 28, 2026, respectively. The reinvestment period and the stated maturity date are both subject to two one-year extensions by mutual agreement. The interest rate charged on the SMBC Funding Facility is based on an applicable spread of either 1.75% or 2.00% over one month SOFR plus a credit spread adjustment of 0.10%, or 0.75% or 1.00% over a “base rate” (as defined in the agreements governing the SMBC Funding Facility), in each case, determined monthly based on the amount of the average borrowings outstanding under the SMBC Funding Facility. As of September 30, 2023, the applicable spread in effect was 1.75%.

________________________________________ (1)The effective stated interest rate of the January 2027 Notes includes the impact of the interest rate swap. In February 2023, the $750 million in aggregate principal amount of unsecured notes that matured on February 10, 2023 (the “2023 Notes”) were redeemed at par plus accrued and unpaid interest for a total redemption price of approximately $763 million. The 2023 Notes bore interest at a rate of 3.500% per annum, payable semi-annually. In connection with the January 2027 Notes, we entered into an interest rate swap to more closely align the interest rate of such liability with our investment portfolio, which consists of primarily floating rate loans. Under the interest rate swap agreement, we receive a fixed interest rate of 7.000% and pay a floating interest rate of one-month SOFR plus 2.585%. We designated this interest rate swap and the related January 2027 Notes as a qualifying hedge accounting relationship. See Note 6 to our consolidated financial statements for the three and nine months ended September 30, 2023 for more information on the interest rate swap. See Note 5 to our consolidated financial statements for the three and nine months ended September 30, 2023 for more information on our debt obligations. As of September 30, 2023, we were in compliance in all material respects with the terms of the 2024 Convertible Notes Indenture and the indentures governing the Unsecured Notes. The 2024 Convertible Notes and the Unsecured Notes are our senior unsecured obligations and rank senior in right of payment to any future indebtedness that is expressly subordinated in right of payment to the 2024 Convertible Notes and the Unsecured Notes; equal in right of payment to our existing and future unsecured indebtedness that is not expressly subordinated; effectively junior in right of payment to any of our secured indebtedness (including existing unsecured indebtedness that we later secure) to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness (including trade payables) incurred by our subsidiaries, financing vehicles or similar facilities.

Risk [Text Block] |  |  |  |  |  |  |  |  |  |  |  | Our business is dependent on bank relationships and recent strain on the banking system may adversely impact us.The financial markets recently have encountered volatility associated with concerns about the balance sheets of banks, especially small and regional banks who may have significant losses associated with investments that make it difficult to fund demands to withdraw deposits and other liquidity needs. Although the federal government has assisted some of these banks and protected depositors, uncertainty remains. Our business is dependent on bank relationships and we are proactively monitoring the financial health of such bank relationships. Continued strain on the banking system may adversely impact our business, financial condition and results of operations.

As of September 30, 2023, the applicable spread in effect was 1.75%. We are also required to pay a letter of credit fee of either 2.00% or 2.125% per annum on letters of credit issued, determined monthly based on the total amount of the borrowing base relative to the total commitments of the Revolving Credit Facility and other debt, if any, secured by the same collateral as the Revolving Credit Facility.

In February 2023, the $750 million in aggregate principal amount of unsecured notes that matured on February 10, 2023 (the “2023 Notes”) were redeemed at par plus accrued and unpaid interest for a total redemption price of approximately $763 million. The 2023 Notes bore interest at a rate of 3.500% per annum, payable semi-annually. In connection with the January 2027 Notes, we entered into an interest rate swap to more closely align the interest rate of such liability with our investment portfolio, which consists of primarily floating rate loans.

We designated this interest rate swap and the related January 2027 Notes as a qualifying hedge accounting relationship. See Note 6 to our consolidated financial statements for the three and nine months ended September 30, 2023 for more information on the interest rate swap. See Note 5 to our consolidated financial statements for the three and nine months ended September 30, 2023 for more information on our debt obligations.
