Explanation of Responses:
( 1)  Disposed of in connection with the Agreement and Plan of Merger ("Merger Agreement") between the Issuer, RenaissanceRe Holdings Ltd. ("RenaissanceRe") and Port Holdings Ltd., dated as of November 23, 2014.
( 2)  Pursuant to the terms of the Merger Agreement, upon closing of the merger, these Common Shares were cancelled and the holder received, per her election, an amount equal to 0.4073 common shares of RenaissanceRe and $24.66 in cash per each of her Common Shares with respect to 59,231 of her Common Shares and $66.00 in cash per each of her Common Shares with respect to 8,330 of her Common Shares. Fractional RenaissanceRe common shares were paid in cash.
( 3)  This consideration amount was prorated as provided for in the Merger Agreement. Specifically, the share consideration was prorated so that the reporting person received 0.4073 RenaissanceRe common shares and $24.66 in cash per each of her 59,231 Common Shares pursuant to which she made the share consideration election, rather than 0.6504 RenaissanceRe common shares.
( 4)  To gain access to the filing system, this line item is being re-reported only to amend footnotes 2 and 3 to state the exact amount of consideration the reporting person received following adjustments due to proration.
