The world's marine insurers collectively lost $3 billion in 1999, Norway's Central Union of Marine Underwriters (CEFOR) said. Cefor's calculation uses the collective experience of marine insurers in Norway - one of the world's major marine insurance markets - and extrapolates the results to the global industry. Cefor's md said that not even in their previous worst case estimates did CEFOR anticipate anything like this. The principal reason for the losses is continuing reduction in insurance premium rates, said Formso. On CEFOR's current estimates, rates in 2000 have dropped to 31 per cent of their 1994 levels.
