Indonesian telecommunications company PT Indosat said Monday its first-quarter net profit slumped to IDR16.7 billion ($1.8 million) from IDR483.7 billion a year earlier.

Indosat, controlled by Qatar Telecom, or QTel, booked a revenue of IDR4.98 trillion in the quarter ended March 31, up 2.1% from IDR4.87 trillion in the previous year.

The company didn't provide a reason for the fall in profit, but will publish detailed earnings on May 8. Its parent QTel, however, attributed its 12% decline in net profit on foreign exchange losses from Indosat.
