NYSE Euronext on Monday reported a net loss of $1.34bn for the fourth quarter, missing expectations, as it was hit by costs related to the merger of NYSE and Euronext. Revenues also suffered because of a new rebate scheme for high frequency customers.

For the full year, the group reported a loss of $738m. Its shares fell 5.5 per cent to $21.65.

The net loss for the fourth quarter and full year 2008 included a pre-tax $1.6bn non-cash charge, primarily due to costs related to the merger of NYSE Group and pan European exchange Euronext.
