Segment Reporting, Measurement Disclosures [Abstract] |
Segment Reporting | SEGMENT REPORTING The Company currently has two reportable segments: Reinsurance and Lloyd's. As of December 31, 2012, the Company undertook a review of its reportable segments and concluded that its former Insurance segment no longer met the quantitative thresholds defined in FASB ASC Topic Segment Reportin g. These operations are not actively involved in pursuing business opportunities and are in run-off; therefore the Company determined these operations no longer require, nor warrant, separate disclosure as a reportable segment. As such, the results of operations of the former Insurance segment have been included in the Other category, and all prior periods presented herein have been reclassified to conform with the current year presentation. The Company's Reinsurance operations are comprised of: (1) property catastrophe reinsurance, principally written through Renaissance Reinsurance and DaVinci; (2) specialty reinsurance, principally written through Renaissance Reinsurance, DaVinci and RenaissanceRe Specialty Risks; and (3) certain property catastrophe and specialty joint ventures, as described herein. The Reinsurance segment is managed by the Company's President and Global Chief Underwriting Officer, who leads a team of underwriters, risk modelers and other industry professionals, who have access to the Company's proprietary risk management, underwriting and modeling resources and tools. The Company's Lloyd's segment includes reinsurance and insurance business written through Syndicate 1458. Syndicate 1458 started writing certain lines of insurance and reinsurance business incepting on or after June 1, 2009. The syndicate was established to enhance the Company's underwriting platform by providing access to Lloyd's extensive distribution network and worldwide licenses and is managed by the Chief Underwriting Officer of European Operations. RenaissanceRe Corporate Capital (UK) Limited (“RenaissanceRe CCL”), an indirect wholly owned subsidiary of RenaissanceRe, is the sole corporate member of Syndicate 1458. The financial results of the Company's strategic investments, weather and energy risk management operations, former Insurance segment and noncontrolling interests are included in the Other category of the Company's segment results. Also included in the Other category of the Company's segment results are the Company's investments in other ventures, investments unit, corporate expenses and capital servicing costs. The Company does not manage its assets by segment; accordingly, net investment income and total assets are not allocated to the segments. A summary of the significant components of the Company's revenues and expenses is as follows:
