German luxury carmaker BMW posted a slight increase in pre-tax profits for 2007, despite a surging euro, the Munich-based company said in results released Thursday, according to dpa. The company, which has its main foreign market in the United States, posted earnings before tax (EBT) of 3.873 billion euros (6.0 billion dollars), up from 3.75 billion euros in 2006. Net profits came in at 3.134 billion euros, up around 9 per cent on the previous year, although this was influenced by changes to company taxes. The company, which has been struggling to raise its margins, said it planned to hike its dividend as much as 51 per cent to 1.06 euros per ordinary share.
