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. The proceeds from the issuance of the Notes listed below are held in reinsurance trusts throughout the duration of the applicable reinsurance agreements and invested solely in U.S. government money market funds with a rating of at least “AAAm” by Standard & Poor’s.
