Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Shares withheld for payment of withholding taxes upon the vesting of restricted shares granted to the reporting person on February 27, 2015.
(2) Shares withheld for payment of withholding taxes upon the vesting of restricted shares granted to the reporting person on January 12, 2016.
(3) Shares withheld for payment of withholding taxes upon the vesting of restricted shares granted to the reporting person on May 16, 2016.
(4) Shares withheld for payment of withholding taxes upon the vesting of restricted shares granted to the reporting person on March 1, 2017.
(5) Grant of restricted common shares of the Issuer pursuant to the RenaissanceRe Holdings Ltd. 2016 Long-Term Incentive Plan (the "2016 Plan"). These shares will vest in four equal annual installments beginning on March 1, 2019.
(6) Grant of performance-based restricted common shares of the Issuer pursuant to the 2016 Plan. These shares will vest following the expiration of the service period on December 31, 2020, subject to the satisfaction of service- and performance-based vesting conditions. The award consists of three substantially equal tranches. The amount awarded represents the maximum potential achievable number of shares. The number of shares in each tranche that ultimately vest is a function of the issuer's total shareholder return relative to the members of a predetermined peer group of companies during a given calendar-year performance period (2018, 2019 or 2020), and is subject to the reporting person's continued employment through the expiration of the service period. If, following the Compensation Committee's determination of total shareholder return for a performance period, there are shares that are no longer eligible to vest, those shares will be immediately forfeited.
(7) Shares withheld for payment of withholding taxes upon the vesting of restricted shares granted to the reporting person on March 3, 2014.
(8) These securities are owned and controlled by a family limited partnership for the benefit of immediate family members of the reporting person and may be deemed to be beneficially owned by the reporting person.
