Collateralized Reinsurance And Trust Agreements	11. COLLATERALIZED REINSURANCE AND TRUST AGREEMENTS Certain subsidiaries of Group have established trust agreements, which effectively use the Company’s investments as collateral, as security for assumed losses payable to certain non-affiliated ceding companies. At September 30, 2020, the total amount on deposit in trust accounts was $ 1,158,783 thousand. The Company reinsures some of its catastrophe exposures with the segregated accounts of Mt. Logan Re. Mt. Logan Re is a Class 3 insurer registered in Bermuda effective February 27, 2013 under The Segregated Accounts Companies Act 2000 and 100 % of the voting common shares are owned by Group. Separate segregated accounts for Mt. Logan Re began being established effective July 1, 2013 and non-voting, redeemable preferred shares have been issued to capitalize the segregated accounts. Each segregated account invests predominantly in a diversified set of catastrophe exposures, diversified by risk/peril and across different geographic regions globally. The following table summarizes the premiums and losses that are ceded by the Company to Mt. Logan Re segregated accounts and assumed by the Company from Mt. Logan Re segregated accounts.

Recoveries under these collateralized reinsurance agreements with Kilimanjaro are primarily dependent on estimated industry level insured losses from covered events, as well as, the geographic location of the events. The estimated industry level of insured losses is obtained from published estimates by an independent recognized authority on insured property losses. Currently, none of the published insured loss estimates for catastrophe events during the applicable covered periods of the various agreements have exceeded the single event retentions or aggregate retentions under the terms of the agreements that would result in a recovery. Kilimanjaro has financed the various property catastrophe reinsurance coverages by issuing catastrophe bonds to unrelated, external investors.
