Stockholders' Equity Note [Abstract]
Shareholders' Equity	SHAREHOLDERS’ EQUITY Dividends The Board of Directors of RenaissanceRe declared dividends of $0.35 per common share, payable to common shareholders of record on March 13, 2020, and the Company paid the dividends on March 31, 2020. The Board of Directors approved the payment of quarterly dividends on the Series C 6.08% Preference Shares, Series E 5.375% Preference Shares and 5.750% Series F Preference Shares to preference shareholders of record in the amounts and on the quarterly record dates and dividend payment dates set forth in the prospectus supplement and Certificate of Designation for the applicable series of preference shares, unless and until further action is taken by the Board of Directors. The dividend payment dates for the preference shares will be the first day of March, June, September and December of each year (or if this date is not a business day, on the business day immediately following this date). The record dates for the preference share dividends are one day prior to the dividend payment dates. The amount of the dividend on the Series C 6.08% Preference Shares is an amount per share equal to 6.08% of the liquidation preference per annum (the equivalent to $1.52 per share per annum, or $0.38 per share per quarter). The amount of the dividend on the Series E 5.375% Preference Shares is an amount per share equal to 5.375% of the liquidation preference per annum (the equivalent to $1.34375 per share per annum, or $0.3359375 per share per quarter). The amount of the dividend on the 5.750% Series F Preference Shares is an amount per share equal to 5.750% of the liquidation preference per annum (the equivalent to $1,437.50 per 5.750% Series F Preference Share per annum, or $359.375 per 5.750% Series F Preference Share per quarter, or $1.4375 per Depositary Share per annum, or $0.359375 per Depositary Share per quarter). During the three months ended March 31, 2020, the Company paid $9.1 million in preference share dividends (2019 - $9.2 million) and $15.4 million in common share dividends (2019 - $14.5 million). Series C 6.08% Preference Shares Redemption In February 2020, RenaissanceRe announced a redemption of all 5 million of its outstanding Series C 6.08% Preference Shares. The Series C 6.08% Preference Shares were redeemed on March 26, 2020 for $125.0 million plus accrued and unpaid dividends thereon. Following the redemption, no Series C 6.08% Preference Shares remain outstanding. Common Shares On March 22, 2019, in connection with the closing of the TMR Stock Purchase, the Company issued 1,739,071 of its common shares to Tokio as part of the aggregate consideration payable to Tokio under the TMR Stock Purchase Agreement. See “Note 3. Acquisition of Tokio Millennium Re” in the Company’s “Notes to the Consolidated Financial Statements” included in the Company’s Form 10-K for the year ended December 31, 2019 for additional information related to the acquisition of TMR. On January 9, 2020, Tokio completed a secondary public offering of these common shares, which represented all of Tokio's remaining ownership in the Company. The Company did not receive any proceeds from Tokio’s sale of its common shares. Share Repurchases The Company’s share repurchase program may be effected from time to time, depending on market conditions and other factors, through open market purchases and privately negotiated transactions. On November 10, 2017, RenaissanceRe’s Board of Directors approved a renewal of its authorized share repurchase program for an aggregate amount of up to $500.0 million. Unless terminated earlier by RenaissanceRe’s Board of Directors, the program will expire when the Company has repurchased the full value of the common shares authorized. The Company’s decision to repurchase common shares will depend on, among other matters, the market price of the common shares and the capital requirements of the Company. During the first quarter of 2020, the Company repurchased 406 thousand common shares in open market transactions at an aggregate cost of $62.6 million and an average price of $154.36 per common share. At March 31, 2020, $437.4 million remained available for repurchase under the share repurchase program. Given the current economic environment and to preserve capital for both risk and opportunity, the Company suspended share repurchases in March 2020. The Company has not engaged in any share repurchase activity during April 2020 or May 2020 to date. In the near term, the Company intends to prioritize capital for deployment into its business; however, we may resume repurchases at any time when we believe it is prudent to do so and without further notice.
