Upon completion of the transaction, shareholders of the Company and shareholders of AXIS would own approximately 51.5% and 48.5% of the Amalgamated Company, respectively. The Amalgamated Company's headquarters would be located in Bermuda. The transaction is subject to approval by the shareholders of both companies, regulatory clearance and other customary closing conditions. Both companies will continue to operate as two independent entities until the closing of the transaction and such conditions are met. On May 3, 2015, the Company and AXIS amended the Amalgamation Agreement (the Amendment to the Amalgamation Agreement) to allow the Company to pay a one-time special dividend of $11.50 per share to PartnerRe common shareholders in connection with the closing of the Amalgamation. See Notes 8 (b) and 10 for further details.
