Construction firm Tobishima Corp. said Wednesday its group net balance returned to the black in fiscal 2000, mainly due to sales of securities holdings.

During the year to March 31, net profit came to 295 million yen, a turnaround from the previous business year's loss of 22.10 billion yen.

Tobishima, known for its expertise in large-sale civil engineering works, posted a 25.6 percent rise in consolidated pretax profit to 6.03 billion yen on a 2.3 percent increase in sales to 323 billion yen.
