Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	VARIABLE INTEREST ENTITIES Upsilon RFO Upsilon RFO is a managed joint venture and a Bermuda domiciled SPI that was formed by the Company primarily to provide additional capacity to the worldwide aggregate and per-occurrence retrocessional property catastrophe excess of loss market. The shareholders (other than the Class A shareholder) participate in substantially all of the profits or losses of Upsilon RFO while their shares remain outstanding. The shareholders (other than the Class A shareholder) indemnify Upsilon RFO against losses relating to insurance risk, and therefore, these shares have been accounted for as prospective reinsurance under FASB ASC Topic Financial Services - Insurance. Upsilon RFO is considered a VIE as it has insufficient equity capital to finance its activities without additional financial support. The Company is the primary beneficiary of Upsilon RFO as it has the power over the activities that most significantly impact the economic performance of Upsilon RFO and has the obligation to absorb expected losses and the right to receive expected benefits that could be significant to Upsilon RFO, in accordance with the accounting guidance. As a result, the Company consolidates Upsilon RFO and all significant inter-company transactions have been eliminated. Other than its equity investment in Upsilon RFO, the Company has not provided financial or other support to Upsilon RFO that it was not contractually required to provide. 2019 During the nine months ended September 30, 2019, Upsilon RFO returned $97.1 million of capital to its investors. In addition, during the nine months ended September 30, 2019, $604.8 million of Upsilon RFO non-voting preference shares were issued to existing investors, including $100.0 million to the Company. At September 30, 2019, the Company’s participation in the risks assumed by Upsilon RFO was 16.7%. At September 30, 2019, the Company’s consolidated balance sheet included total assets and total liabilities of Upsilon RFO of $2.8 billion and $2.8 billion, respectively (December 31, 2018 - $2.2 billion and $2.2 billion, respectively). 2018 During 2018, $856.7 million of Upsilon RFO non-voting preference shares were issued to existing investors, including $109.8 million to the Company. At December 31, 2018, the Company’s participation in the risks assumed by Upsilon RFO was 14.0%. Payments for certain of the shares issued during 2018 that were received by the Company prior to January 1, 2018 and were included in other liabilities on the Company’s consolidated balance sheet at December 31, 2017, and in other operating cash flows on the Company’s consolidated statements of cash flows for 2017. During 2018, in connection with the issuance of the non-voting preference shares of Upsilon RFO, other liabilities were reduced by this amount, and reinsurance balances payable were increased by an offsetting amount, with corresponding impacts to other operating cash flows and the change in reinsurance balances payable on the Company consolidated statements of cash flows for 2018. Vermeer Vermeer is an exempted Bermuda reinsurer that provides capacity focused on risk remote layers in the U.S. property catastrophe market. Vermeer is considered a VIE as it has voting rights that are not proportional to its participating rights. The Company is the primary beneficiary of Vermeer as it has power over the activities that most significantly impact the economic performance of Vermeer and has the obligation to absorb expected losses and the right to receive expected benefits that could be significant to Vermeer, in accordance with the accounting guidance. The portion of Vermeer’s earnings owned by PGGM is recorded in the consolidated statements of operations as net income attributable to redeemable noncontrolling interests. See “Note 9. Noncontrolling Interests” for additional information regarding Vermeer. Other than the Company’s minimal equity investment, it has not provided any financial or other support to Vermeer that it was not contractually required to provide. At September 30, 2019, the Company’s consolidated balance sheet included total assets and total liabilities of Vermeer of $820.4 million and $38.7 million, respectively (December 31, 2018 - $600.4 million and $0.4 million, respectively). In addition, the Company’s consolidated balance sheet included redeemable noncontrolling interests associated with Vermeer of $781.7 million at September 30, 2019 (December 31, 2018 - $600.0 million). Fibonacci Re Fibonacci Re, a Bermuda-domiciled SPI, was formed to provide collateralized capacity to Renaissance Reinsurance and its affiliates. Upon issuance of a series of notes by Fibonacci Re, all of the proceeds from the issuance are deposited into collateral accounts, separated by series, to fund any potential obligation under the reinsurance agreements entered into with Renaissance Reinsurance underlying such series of notes. The outstanding principal amount of each series of notes generally is expected to be returned to holders of such notes upon the expiration of the risk period underlying such notes, unless an event occurs which causes a loss under the applicable series of notes, in which case the amount returned is expected to be reduced by such noteholder’s pro rata share of such loss, as specified in the applicable governing documents of such notes. In addition, holders of such notes are generally entitled to interest payments, payable quarterly, as determined by the applicable governing documents of each series of notes. RUM receives an origination and structuring fee in connection with the formation and operation of Fibonacci Re. The Company concluded that Fibonacci Re meets the definition of a VIE as it does not have sufficient equity capital to finance its activities. The Company evaluated its relationship with Fibonacci Re and concluded it is not the primary beneficiary of Fibonacci Re as it does not have power over the activities that most significantly impact the economic performance of Fibonacci Re. As a result, the Company does not consolidate the financial position or results of operations of Fibonacci Re. The only transactions related to Fibonacci Re that will be recorded in the Company’s consolidated financial statements will be the ceded reinsurance agreements entered into by Renaissance Reinsurance that are accounted for as prospective reinsurance under FASB ASC Topic Financial Services - Insurance, and the fair value of the participating notes owned by the Company. Other than its investment in the participating notes of Fibonacci Re, the Company has not provided financial or other support to Fibonacci Re that it was not contractually required to provide. The fair value of the Company’s investment in the participating notes of Fibonacci Re is included in other investments. Net of third-party investors, the fair value of the Company’s investment in Fibonacci Re was $1.0 million at September 30, 2019 (December 31, 2018 - $6.0 million). Renaissance Reinsurance entered into ceded reinsurance contracts with Fibonacci Re with ceded premiums written of $87 thousand and ceded premiums earned of $87 thousand during the nine months ended September 30, 2019 (2018 - $9.1 million and $6.8 million, respectively). During the nine months ended September 30, 2019, Renaissance Reinsurance ceded $7.5 million of net claims and claim expenses to Fibonacci Re (2018 - $Nil) and as of September 30, 2019 had a net reinsurance recoverable of $7.5 million from Fibonacci Re (December 31, 2018 - $Nil). Langhorne The Company and Reinsurance Group of America, Incorporated formed Langhorne, an initiative to source third party capital to support reinsurers targeting large in-force life and annuity blocks. In connection with Langhorne, as of September 30, 2019 the Company has invested $1.7 million in Langhorne Holdings (December 31, 2018 - $1.3 million), a company that owns and manages certain reinsurance entities within Langhorne. In addition, as of September 30, 2019 the Company has invested $0.1 million in Langhorne Partners (December 31, 2018 - $0.1 million), the general partner for Langhorne and the entity which manages the third-party investors investing into Langhorne Holdings. The Company concluded that Langhorne Holdings meets the definition of a VIE as the voting rights are not proportional with the obligations to absorb losses and rights to receive residual returns. The Company evaluated its relationship with Langhorne Holdings and concluded it is not the primary beneficiary of Langhorne Holdings, as it does not have power over the activities that most significantly impact the economic performance of Langhorne Holdings. As a result, the Company does not consolidate the financial position or results of operations of Langhorne Holdings. The Company separately evaluated Langhorne Partners and concluded that it was not a VIE. The Company accounts for its investments in Langhorne Holdings and Langhorne Partners under the equity method of accounting, one quarter in arrears. The Company anticipates that its absolute investment in Langhorne will increase, perhaps materially, as in-force life and annuity blocks of businesses are written. The Company expects its absolute and relative ownership in Langhorne Partners to remain stable. Other than its current and committed future equity investment in Langhorne, the Company has not provided financial or other support to Langhorne that it was not contractually required to provide. Shima Re and Norwood Re Shima Re and Norwood Re were acquired on March 22, 2019 in connection with the acquisition of the TMR Group Entities. See “Note 3. Acquisition of Tokio Millennium Re” for additional information related to the acquisition of the TMR Group Entities. Shima Re is a Bermuda domiciled Class 3 insurer. Norwood Re is a Bermuda domiciled SPI and is wholly owned by the Norwood Re Purpose Trust. Shima Re and Norwood Re are each registered as a segregated accounts company and each provides third-party investors with access to reinsurance risk formerly managed by the TMR Group Entities. Following the closing of the acquisition, some of the TMR third-party capital vehicles’ legacy portfolios of in-force and expired contracts were transferred to other stop loss reinsurance providers. The maximum remaining exposure of each segregated account is fully collateralized and is funded by cash and term deposits or investments as prescribed by the participant thereto. Shima Re and Norwood Re are considered VIEs as they have voting rights that are not proportional to their participating rights. The Company evaluated its relationships with Shima Re and Norwood Re and concluded it is not the primary beneficiary of any segregated account, as it does not have power over the activities that most significantly impact the economic performance of any segregated account. As a result, the Company does not consolidate the financial position or results of operations of Shima Re, Norwood Re or their segregated accounts. The Company has not provided any financial or other support to any segregated account of Shima Re or Norwood Re that it was not contractually required to provide.
