Under the Lloyd's system, insurance syndicates cannot close their accounts for years in which they are not able to calculate their losses because of outstanding liabilities. Charles Sturge of insurance analyst Chatset reckons that syndicates have 42 of these 'open years'. That figure will rise to about 60 by the end of this year - and the final total could be 150. Sturge believes that if Lloyd's wants to buy out its unlimited liability investors, it will have to create another Equitas, the fund set up in the early Nineties to ringfence all the old asbestos and pollution losses at Lloyd's.
