Argo Group International Holdings, Ltd. (NASDAQ: AGII), an international underwriter of specialty insurance and reinsurance products, today announced former Ariel Re chief executive officer, Ryan Mather, will serve as Argo Group's global head of reinsurance leading all reinsurance operations. This announcement comes only a day after Argo Group announced the closing of the Ariel Re transaction on Feb. 6. "Ariel Re and Argo Group are a terrific fit - operationally and culturally," says Argo Group CEO Mark E. Watson III. "Ryan's leadership and collaboration were key factors in our ability to finalize this agreement and begin implementing the company's integration plan so swiftly. This is reflective of the teamwork and outstanding results we expect to see in the future." Mather's organization will retain the Ariel Re brand as a member of Argo Group, and he will report directly to Jose A. Hernandez, head of Argo Group's International Business. "This transaction improves the company's ability to manage through changing market cycles," said Hernandez. "It also adds new capabilities that can be leveraged throughout the entire organization, including Ariel Re's unique modeling and risk analysis tools, which enhance Argo's already robust underwriting analytics. "Under Ryan's leadership, Ariel Re and Argo Re have combined to become a market-leading business and will make a meaningful and immediate contribution to earnings and return on equity."
