The evolution of a weather risk management company

MSI GW’s weather risk management team began in the industry during 1999 as one of the first market participants and quickly established itself as a leader in the industry. During the early years, MSI GW’s staff was part of Aquila, Inc., a Fortune 100 energy merchant based in Kansas City, Missouri.

In 2003, as part of a major asset sell-off, Aquila sold the MSI GW business to Ramsey Financial, a Midwestern-based asset management firm. Mitsui Sumitomo Insurance Co., Ltd. (MSI) and Hannover Ruckversicherung AG (Hannover Re), both long time capital partners in the business with Aquila, continued their origination and capital support relationships following this sale. Subsequently, in 2007, MSI acquired the business and preserved the capital support of Hannover Re thus creating MSI GW as it is known today. During these changes in ownership, the core MSI GW team has remained intact and continues to operate the business today—the team’s collective experience is unmatched in the industry.
