A syndicate would provide liability coverage.

Marsh & McLennan Cos. and Johnson & Higgins, two of the nation’s largest insurance brokerage firms, are trying to persuade property-casualty insurers to form an underwriting syndicate to provide major corporations with $75 million of hard-to-find coverage each. Until 1984, some major companies bought as much as $900 million of liability coverage, but currently it is hard for a company to buy even $100 million--and impossible if they are in high-risk industries such as chemicals and pharmaceuticals.
