Insurance [Abstract]
Third party reinsurance	Third party reinsurance In the normal course of business, Sirius Group seeks to protect its businesses from losses due to concentration of risk and losses arising from catastrophic events by reinsuring with third-party reinsurers. Sirius Group remains liable for risks reinsured in the event that the reinsurer does not honor its obligations under reinsurance contracts. At March 31, 2020, Sirius Group had reinsurance recoverables on paid losses of $85.7 million and reinsurance recoverables of $444.2 million on unpaid losses. At December 31, 2019, Sirius Group had reinsurance recoverables on paid losses of $73.9 million and reinsurance recoverables of $410.3 million on unpaid losses. Because retrocessional reinsurance contracts do not relieve Sirius Group of its obligation to its insureds, the collectability of balances due from Sirius Group's reinsurers is important to its financial strength. Sirius Group monitors the financial strength and ratings of retrocessionaires on an ongoing basis. Uncollectible amounts historically have not been significant. (See Note 7.)
