Second-quarter pretax profit came in at 1.04 billion kronor compared with 180 million kronor, and massively above analysts average expectations of 238 million kronor.
Sales also grew in the second quarter, reaching 17.87 billion kronor compared with 13.81 billion in the same quarter last year and expert forecasts of 16.8 billion kronor.

Capital gains for the full year 2002, including costs for phasing in and phasing out aircraft, would amount to at least 350 million kronor, it said.
Brokers welcomed the results.
