Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	1. ORGANIZATION Ares Strategic Income Fund (together with its consolidated subsidiaries, the “Fund”) is a Delaware statutory trust formed on March 15, 2022. The Fund is a closed-end management investment company that has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “Investment Company Act”). The Fund has elected to be treated as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”) and operates in a manner so as to qualify for the tax treatment applicable to RICs. The Fund is externally managed by Ares Capital Management LLC (“Ares Capital Management” or the Fund’s “investment adviser”), a subsidiary of Ares Management Corporation (“Ares Management” or “Ares”), a publicly traded, leading global alternative investment manager, pursuant to an investment advisory and management agreement. Ares Operations LLC (“Ares Operations” or the Fund’s “administrator”), a subsidiary of Ares Management, provides certain administrative and other services necessary for the Fund to operate. The Fund’s investment objective is to generate current income and, to a lesser extent, long-term capital appreciation. The Fund seeks to invest primarily in first lien senior secured loans, second lien senior secured loans, subordinated secured and unsecured loans, subordinated loans (which in some cases include equity and/or preferred components) and other types of credit instruments which may include commercial real estate mezzanine loans, real estate mortgages, distressed investments, securitized products, notes, bills, debentures, bank loans, convertible and preferred securities, infrastructure debt and government and municipal obligations, made to or issued by U.S. middle-market companies, which the Fund generally defines as companies with annual EBITDA between $10 million and $250 million. As used herein, EBITDA represents annual net income before net interest expense, income tax expense, depreciation and amortization. The Fund expects that a majority of its investments will be in directly originated loans. For cash management and other purposes, the Fund also invests in broadly syndicated loans and other more liquid credit investments, including in publicly traded debt instruments and other instruments that are not directly originated. The Fund primarily invests in illiquid and restricted investments, and while most of the Fund’s investments are expected to be in private U.S. companies (the Fund generally has to invest at least 70% of its total assets in “qualifying assets,” including private U.S. companies), the Fund may also invest from time to time in non-U.S. companies. The Fund’s portfolio may also include equity securities such as common stock, preferred stock, warrants or options, which may be obtained as part of providing a broader financing solution. Under normal circumstances, the Fund will invest directly or indirectly at least 80% of its total assets (net assets plus borrowings for investment purposes) in debt instruments of varying maturities. The Fund has received an exemptive relief order from the Securities and Exchange Commission (the “SEC”) that permits the Fund to offer to sell any combination of three classes of its common shares, including Class S shares, Class D shares and Class I shares (“Common Shares”). The Fund publicly offers its Common Shares on a continuous basis, pursuant to an offering registered with the SEC (the “Offering”). The share classes have different ongoing shareholder servicing and/or distribution fees. The purchase price per share for each class of Common Shares equals the Fund’s net asset value (“NAV”) per share, as of the day preceding the effective date of the monthly share purchase. The Offering is a “best efforts” offering, which means that the Intermediary Manager (as defined below) for the Offering will use its best efforts to sell Common Shares, but is not obligated to purchase or sell any specific amount of Common Shares. The Fund also engages in offerings of its unregistered Common Shares to non-U.S. investors pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) and Regulation S promulgated under the Securities Act.
