What the 8-K discloses
Item 5.02 of the filing covers the departure of certain officers, and the single substantive disclosure is Bock's exit from the co-chief executive seat. Blackstone Secured Lending Fund stated the resignation was not the result of any disagreement relating to Blackstone or the Fund's operations, policies, or practices. That clause is standard SEC language, but its presence addresses directly what the departure was not about.
The filing credits Bock with contributions during his tenure to the Blackstone Credit & Insurance ("BXCI") perpetual credit funds platform, a group that includes the fund. BXCI acknowledged his service and extended good wishes for his future work.
