  NET LOSS: The Indian telecom company swung to a net loss of 52.37 billion Indian rupees ($692.6 million) for the quarter ended March 31 from a net profit of INR1.07 billion a year earlier. That was worse than the estimated INR854 million in net loss from a FactSet poll of analysts. 


  REVENUE: Fourth-quarter revenue, including other income, rose 15% to INR238.22 billion. 


  WHAT WE WATCHED: 


  --LICENSE FEES: The bottom line was hit by exceptional charges of INR70.04 billion, primarily the costs related to longstanding telecom-license disputes with the government. 


  --UNDERLYING GROWTH: Many of its business segments showed earnings improvement. Operating profit rose 34% for its mobile services in Africa and 72% for information-technology services for businesses and governments, while the mobile services in India swung to profit.
