The Lloyd's of London insurance market revealed that record claims from disasters including the Chilean earthquake and U.S. oil spill halved its profits, and said it saw no respite from a steady decline in prices. Lloyd's, which traces its origins back 322 years to a London coffee house where wealthy merchants insured ships, on Tuesday posted a pretax profit of 628 million pounds ($994 million) for the first half of 2010, down from 1.32 billion a year earlier.
