Schedule 13G regulatory

"Item 1. (a) Name of issuer: Blackstone Long-Short Credit Income Fund"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

beneficial ownership regulatory

"Item 4. Ownership (a) Amount beneficially owned: See response to item 9"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

shared voting and dispositive power financial

"SIA and SFI possess shared voting and investment power over securities"

Rule 13d-4 regulatory

"Pursuant to Rule 13d-4 of the Securities Exchange Act of 1934"

Form N-CSR regulatory

"based on 12,708,275 shares outstanding as of December 31, 2025, as reported in the Issuer's Report on Form N-CSR"

Form N-CSR is a regulatory filing that U.S.-registered investment funds use to deliver certified shareholder reports to regulators and the public, including audited financial statements, a snapshot of portfolio holdings, fee and performance information, and governance disclosures. For investors it acts like a fund’s report card and safety check—providing verified details needed to assess a fund’s financial health, costs, holdings and compliance so you can compare funds, monitor risks and spot red flags.
