(Telecompaper) BT said it booked a GBP 145 million non-cash writedown in its fiscal second quarter to September following an internal probe into "inappropriate management behaviour" in its BT Italia operations. The announcement came as the group posted a 35 percent increase in reported revenue in the period to GBP 6.007 billion, thanks mainly to the EE acqusition. On a pro forma basis and excluding transit revenues, sales were up 1.1 percent year-on-year, led by growth in the consumer division.
