His appointment is subject to receipt of customary regulatory approvals. Scott Kirk succeeds John Worth, who will be leaving Aspen.

Aspen’s Chief Executive Officer, Chris O’Kane, said: “I’m pleased to announce Scott’s promotion to the position of Group CFO. Over the course of the seven years that Scott has been at Aspen, he has proven to be a highly talented strategic thinker and key financial leader, both in his Group roles as Group Financial Controller and Group Head of Finance, and most recently as CFO of Aspen’s insurance business. As CFO of Aspen Insurance, he has played an integral role in a number of value-creating initiatives, including the successful growth of Aspen’s U.S. Insurance operation. We are excited that Scott is taking on this new role at Aspen.

“Aspen continues to perform well and we remain on track to achieve an operating return on equity comfortably in excess of 10% in 2014, assuming normal loss experience, as well as our longer-term outlook of operating return on equity of 11% in 2015 and between 11% and 12% in 2016 (1). Scott is a strong financial leader and will play a key role as we continue to execute on our strategic plan and build value for shareholders.”

Chris O’Kane added: “John Worth has made a valuable contribution to Aspen and in particular strengthened the operational side of our Finance function and enhanced our expense discipline. We would like to thank him for what he has done for Aspen and we wish him all the best in his future endeavors.”

(1) The outlook for 2015 and 2016 assumes normal loss experience and the current insurance rate environment. Our outlook in 2015 and 2016 in particular is necessarily subject to heightened sensitivity in relation to assumptions which are likely to be the subject of future change, amendment, update and review, as necessary. For example, our assumptions for rising interest rates in 2015 and 2016 are subject to and dependent upon the anticipated and actual monetary policy decisions taken by the central banks in the jurisdictions in which we operate. Our assumptions are also based on the retention of our senior underwriters and client relationships. In addition, the models underlying our normal loss experience assumptions will produce different illustrative loss patterns if the modeling assumptions are changed. While recent decreases in pricing in certain business lines, if sustained, are expected to have an adverse effect on operating return on equity, Aspen continues to identify actions in each of its three operating return on equity levers - optimization of the business portfolio, capital efficiency and enhancing investment returns - to help mitigate the impact of pricing declines on operating return on equity.
