Mobile operator Ooredoo Kuwait raised its dividend for 2015 despite swinging to a fourth-quarter net loss on Saturday, according to Reuters calculations, resuming a lengthy earnings slump.

The subsidiary of Qatar's Ooredoo competes domestically with Zain and Saudi Telecom affiliate Viva. It recorded higher earnings in the third quarter but has still reported falling profits in 12 of the previous 16 quarters.

Ooredoo Kuwait made a net loss of KD1.4 million ($4.7 million) in the three months to December 31, Reuters calculated in lieu of a quarterly breakdown, based on the company's annual earnings statement.

This compares with breaking even in the same period of 2014.

Ooredoo Kuwait, which also has operations in Algeria, Tunisia, the Maldives and the Palestinian Territories, said in a statement its board had recommended paying an annual cash dividend of 0.1 dinar per share for 2015.

This compares with a cash payout of 0.070 dinar per share for 2014.

The operator's 2015 profit was KD26.7 million, down from KD45.7 million in 2014, the statement said.

Full-year revenue was KD718 million, down four per cent on a year earlier, with the company citing foreign exchange losses for the decline.

Its customer base stood at 24 million at the end of 2015, up three per cent year on year, the statement added.-Reuters
