Net profit was at 3.78 billion Singapore dollars (2.5 billion US), while operating revenue stood at 13.15 billion dollars, little changed from the previous financial year.

For the fourth quarter to March, net profit declined 41.2 percent to 989 million dollars, with the fall magnified by a 618 million-dollar lump sum gain in the same period the year before, SingTel said in a statement.

"With lower exceptional gain and higher tax expense, net profit after tax fell 9.2 percent to 3.78 billion dollars," SingTel said.

Profit before exceptional items however grew a modest 7.9 percent to 3.56 billion dollars for the full year, supported by robust contributions from its regional mobile associates, which grew 25.7 percent to 2.07 billion dollars.

The homegrown Singapore firm's overseas associates contributed 43 percent of the underlying profit, up from 37 percent the previous year.
