The rating actions reflect RenRe's superior level of risk-adjusted capitalization, the strength and depth of its management team and the ability of the company to deliver strong long-term profitability over the course of the insurance cycle. The company is widely recognized for its thoughtful leadership in enterprise risk management and as a pioneer in third-party capital management. In that regard, RenRe maintains its superior market reputation as a leader in state-of-the-art property catastrophe modeling and risk optimization, which has attracted capital from outside investors to form several successful joint ventures, including DaVinci and Top Layer Reinsurance Ltd.

The ratings of DaVinci recognize its solid operating performance over the past several years and the maintenance of its strong risk-adjusted capitalization. DaVinci's profile is enhanced due to its affiliation with RenRe.

The ratings of RenRe Specialty Risks, RenRe US and RenRe Specialty US Ltd. acknowledge their strong risk-adjusted capitalization, sound business plans and strategic positioning for writing casualty specialty risks. The ratings are enhanced based on implicit and explicit support. In addition, the aforementioned companies' profiles are enhanced due to their affiliation and branding as RenRe companies.

Offsetting these strengths is RenRe's exposure to high severity losses associated with catastrophic events. The global reinsurance market in general, and specifically the property catastrophe segment, has been experiencing overcapacity and resulting price pressures on rates that have pressured historically high return measures. The negative outlooks on the ICRs of RenRe and DaVinci reflect these adverse market conditions. The pricing pressure coupled with the flow of alternative capital and increased retentions of primary companies have exacerbated the pressure on return measures, which may be sustained for a long period of time. This pressure rationalizes RenaissanceRe's acquisition of Platinum Underwriters Holdings, Ltd. in 2015. RenRe's strategy to diversify its core property catastrophe book of business is ongoing.

Factors that could return the negative outlooks to stable include superior operating results coupled with strong risk-adjusted capitalization over the long term. Factors that could lead to a downgrade include outsized catastrophe or investment losses, weak or strained risk-adjusted capitalization or continued downward pressure on property catastrophe rates, which is currently the organizations main line of business.
