Net income for the year was $101.4 million ($2.90 a share), compared with $98 million ($2.96) in the prior year, the company said. Sales for the year totaled $2.5 billion, up 8 percent.

James River officials said earnings for the year were affected adversely in the first half by higher operating costs associated with the introduction of Northern tissues and napkins and Brawny towels in Northeast markets; by pricing pressures in the food service, communication papers and pulp areas; and by slack demand for specialty industrial and packaging papers during mid-year.

Meanwhile, fourth-quarter net income rose 6 percent, to $34 million (98 cents) from $32 million (94 cents) a year earlier. Fourth-quarter sales were $645 million, down 5 percent from $677 million.
