PartyGaming's interim results have revealed a pre-tax loss of US $47.1m (£23.5m), due to the closure of its US operations.
It follows the passing of the Unlawful Internet Gambling Enforcement Act (UIGEA).
Total revenue for the group was down 68 per cent to US $212.5m, compared with US $661.9m in the same period last year.
However, Party said the revenue figure reflected the overall performance of its continuing operations (Europe, Middle East and Africa) and marked a 42 per cent increase on the US $149.8m achieved in the six month period to the end of June 2006.
The Isle of Man company, the world’s largest internet poker company, highlighted the "spectacular" growth of its casino operations, which revealed a 218 per cent rise in net casino revenue compared with 2006, and said that even allowing for first-time contributions from Empire Online and Intercontinental Online Gaming since January 2007, casino revenues now made up 30 per cent of the group's total revenues, compared with 14 per cent in 2006.
