Group Structure

Financial Security
Having the full backing of our parent company in Japan brings with it the coveted Standard & Poor’s rating of AA (Very Strong). Our Lloyd’s vehicle, Syndicate 3210, is managed by Mitsui Sumitomo Insurance Underwriting at Lloyd’s (MSIUL). The Syndicate’s capital is provided by MSI Corporate Capital Ltd. (MSICC), a corporate member of Lloyd’s. The ‘chain of security’ reflects the structure of the Lloyd’s chain of security.

Our Financial Solutions business, Mitsui Sumitomo Insurance (London) Ltd, benefits from the financial security that comes from the backing of our parent company in Japan (Standard & Poor’s coveted AA rating), which provides full financial backing through the provision of a Credit Support Agreement.
