DEBT AND FINANCING ARRANGEMENTS	Letters of CreditEffective March 31, 2021, certain of AXIS Capital’s operating subsidiaries (the "Participating Subsidiaries") amended their existing $750 million secured letter of credit facility to: (i) extend the expiration date of the $250 million secured letter of credit facility to March 31, 2022, with each letter of credit provided pursuant to such credit facility having a tenor not to extend beyond March 31, 2023; (ii) reduce the utilization capacity available under the $250 million secured letter of credit facility to $150 million, reducing the maximum aggregate utilization capacity of the credit facility from $750 million to $650 million; and (iii) make administrative changes to the remaining $500 million secured letter of credit facility. Letters of credit issued under the secured letter of credit facility are principally used to support the reinsurance obligations of the Participating Subsidiaries. The Participating Subsidiaries are subject to certain covenants, including the requirement to maintain sufficient collateral to cover the obligations outstanding under the facilities. Such obligations include contingent reimbursement obligations for outstanding letters of credit and fees payable to Citibank Europe plc. In the event of default, Citibank Europe plc may exercise certain remedies, including the exercise of control over pledged collateral and the termination facility to any or all of the Participating Subsidiaries.
