The audit committee chairmanship went to Steven Bossi rather than to the incoming appointee, who joins the committee as a member.

August 3, 2026

Diameter Credit Company reshuffled its board over consecutive days at the end of July, losing an independent trustee, seating a replacement within 24 hours and moving leadership of its audit committee to a different member.

Daniel Kasell notified the credit fund on July 29 that he was resigning from its board of trustees and from all board committees, effective immediately. The company reported that the departure did not stem from any disagreement with the fund, its investment adviser or their affiliates over operations, policies or practices.

The board acted the following day, appointing Daniel Gish, 42, as an independent trustee, also effective immediately. Gish takes seats on the audit committee and the nominating and governance committee. In connection with Kasell’s departure, Steven Bossi was appointed chairman of the audit committee.

A traded-credit resume

Gish arrives from Marshall Wace, where he ran a long/short investment grade credit strategy as a portfolio manager from 2024 to 2026. He previously held portfolio manager duties at Verition Fund Management and, before that, was an executive director at UBS. He holds a bachelor’s degree in economics from Middlebury College.

That track record sits on the traded side of credit rather than the direct origination side that anchors the fund’s own portfolio, a distinction worth registering for a trustee joining the committee that oversees financial reporting.

No compensatory arrangement accompanied the appointment. The company also addressed the standard independence questions, reporting that Gish:

• has not entered into, and does not expect to enter into, any material plan, contract, arrangement, grant or award tied to becoming a trustee;
• was not appointed under any arrangement or understanding with another person;
• has no family relationship with other trustees or executive officers;
• was not a participant in any transaction involving the company since the start of its last fiscal year.

Why the seat matters

Board composition draws closer attention at vehicles without a listed market for their shares. Holders have no continuous price to read as a verdict on the adviser and lean more heavily on the governance layer overseeing it, with the audit committee at the center of that layer. A new member and a new chairman arriving in the same week is therefore a change worth tracking, even absent any dispute.
