The Financial Post reports in its Tuesday edition Quebec forest company Tembec says it endured a tough winter quarter that resulted in a $40-million loss. A Canadian Press dispatch to the Post says the loss amounted to 40 cents per share, which was deeper than a year-earlier loss of 28 cents per share or $28-million. Tembec said winter weather resulted in higher energy costs and lower efficiency. A weaker Canadian dollar produced a $37-million loss related to debt issued in U.S. dollars. Tembec said the weaker Canadian dollar had some positive impact on sales but that was partially offset by weak demand and pricing for some of its products. Overall sales were down nearly 4 per cent, dropping to $348-million in the second quarter ended March 28 from $362-million a year earlier. Nearly one-third of Tembec's revenue was from sales of specialty pulp segment, another third was from forest products such as lumber, and the remainder was from sales of paper and paper pulp. Tembec closed Monday at $2.58, down 30 cents on the Toronto Stock Exchange.
