KDD Corp. said Thursday that its consolidated net balance returned to the black in fiscal 1999, due to brisk earnings from domestic phone services and a number of one-off factors, including mammoth gains from securities sales.

For the year through March 31, the international telecom titan, which recently diversified into domestic telecom services, said its consolidated net profit was 7.31 billion yen, a turnaround from last year's loss of 1.93 billion yen.

Group pretax profit ballooned to 23.11 billion yen, up 503.3 percent from 3.83 billion yen. Operating revenues came to 597.31 billion yen, up 47.2 percent.
