Neptune Orient Lines Ltd. (NOL) expects a better second half and overall profit in the current year. NOL said the bottoming out of the Asian economic crisis had resulted in higher cargo volumes in most sectors. Freight rates out of Asia to Europe and North America had also increased since mid-year, it said in comments accompanying its result. NOL reported last Wednesday an interim net profit, the first time in two years, but results were disappointing as gains came mostly from non-recurring items. The national shipping giant reported a net profit of S$10.02 million for the six months ended June 30, 1999 against a net loss of S$240.76 million a year earlier.
