Arch Capital Group, a provider of insurance, reinsurance and mortgage insurance, agreed to acquire a 29.5% stake in Coface, a France-based provider of trade credit insurance, from Natixis, a French corporate and investment bank, for $520m. “This is a long-term, strategic investment in Coface, and fits with Arch’s efforts to develop uncorrelated sources of underwriting income. Our companies share a focus on specialty underwriting where knowledge and expertise create value for our clients, and trade credit contributes to Arch’s specialty-driven business model,” Marc Grandisson, Arch’s Chief Executive Officer.
