Hamilton Re substituted an unsecured letter with a new $260 million letter of credit expiring December 31, 2029, carrying a fee of 150.0 basis points per annum on issued amounts. This supports Funds at Lloyd’s for Syndicate 4000, a common capital mechanism at Lloyd’s.

A separate UBS facility was renewed at the greater of $25 million and the issued-and-outstanding amount, capped at $75 million, through October 23, 2026. The documents list lenders (ING, Commerzbank, Deutsche Bank, UBS) and extend availability and tenor but do not change core usage.
