Internet business operator Livedoor Co. said Thursday its group sales in the first nine months of its 2005 business year saw a threefold jump from a year before to 52.28 billion yen due mainly to a 3.5-fold sales leap at its Net-based financing segment.

In a consolidated earnings report for the period from last Oct. 1 to June 30, Livedoor said its net profit more than doubled to 4.70 billion yen.

But net profit per share in the period dived to 6.07 yen from 41.95 yen in the same period a year earlier as a result of a sharp increase in the number of the company's outstanding shares.

Pretax profit amounted to 5.20 billion yen, up 53.0 percent.
