Argo Group International Holdings, Ltd. (NasdaqGS: AGII), an international underwriter of specialty insurance and reinsurance products, announced today the appointment of Andrew Carrier to the newly created position of group chief underwriting officer. In his expanded role, Mr. Carrier will oversee underwriting across Argo Group's worldwide operations and will report to Argo Group Chief Executive Officer Mark E. Watson III. Mr. Carrier will retain his current responsibilities as president of Argo Re and as underwriting director for Argo International.

?In addition to building a leading reinsurance operation in Bermuda in a short period of time, Andrew has been a key contributor on the Group executive team,? said Mr. Watson. ?As we continue to broaden our underwriting platform, Andrew's enterprise-wide view of risk and opportunity will be increasingly valuable.?

The company also announced the resignation of Julian Enoizi, chief executive officer of Argo International in London. Mr. Enoizi will be leaving his position as of March 4 to pursue other business interests.

?Since taking the helm in 2009, Julian introduced the disciplines to create a stable platform on which to base the future growth of Argo International,? said Mr. Watson. ?Having established this base and overseen expansion into new classes of business, Julian has chosen to seek out a new challenge. He will be staying on through the beginning of March to ensure a smooth transition.?

Jeffrey Radke has been appointed managing director of Argo International, pending approval of the Financial Services Authority in the UK, and will assume Mr. Enoizi's responsibility for overseeing Argo Group's syndicate at Lloyd's. Mr. Radke will report to Mr. Watson.

?Jeff has worked on a number of strategic initiatives for Argo Group since its formation in 2007. Having worked with the syndicate since 2009 and currently serving as director of syndicate management, the expansion of his responsibilities to managing director of the syndicate is a natural evolution,? said Mr. Watson.

Since joining Argo Group in 2007, Mr. Carrier has served as president of Argo Re, Argo Group's reinsurance segment based in Bermuda, and as underwriting director for Argo International. Prior to joining Argo Group, Mr. Carrier was active underwriter for Kiln Group's Syndicates 510 and 557 at Lloyd's. During his 23-year career at Kiln, Mr. Carrier oversaw the organization's international reinsurance portfolio, was director of R.J. Kiln & Company Ltd. and a member of the group executive team.

Prior to serving as director of syndicate management for Argo's syndicate at Lloyd's, Mr. Radke was chief executive officer of PXRE Group from 2003 until 2007 when it merged with Argonaut Group, Inc. to form Argo Group International Holdings, Ltd. He joined PXRE as executive vice president responsible for underwriting in 2000. Prior to joining PXRE, Mr. Radke held senior positions at CAT Ltd. and Guy Carpenter and Co.
