Occasionally, however, the cost of our float will spike severely. That will occur because of our heavy involvement in the super-cat business, which by its nature is the most volatile of all insurance lines. In this operation, we sell policies that insurance and reinsurance companies purchase in order to limit their losses when mega-catastrophes strike. Berkshire is the preferred market for sophisticated buyers: When the “big one” hits, the financial strength of super-cat writers will be tested, and Berkshire has no peer in this respect.
