Another thing you should consider with any insurance company is the quality of the firm there are rating agencies like A.M. Best here is a note from their site:

A Best's Rating is an independent third-party evaluation that subjects all insurers to the same rigorous criteria, providing a valuable benchmark for comparing insurers, regardless of their country of domicile. Such a benchmark is increasingly important to an international market that looks for a strong indication of stability in the face of widespread deregulation, mergers, acquisitions and other dynamic factors.

A.M. Best assigns three types of ratings. All are independent opinions, based on a comprehensive quantitative and qualitative evaluation, of a company's balance sheet strength, operating performance and business profile. They are not a warranty of a company's financial strength and ability to meet either its obligations to policyholders or its financial obligations
