Tiger said the rising yen will hurt its results.

The Los Angeles air freight and trucking firm said the yen’s higher value in relation to the dollar would cause its first-quarter losses to be wider than expected. But Robert P. Jensen, Tiger’s president and chief executive, said the company would show “significant improvement” for all of 1986, compared to last year’s loss of $72.7 million. He declined to predict a 1986 profit, however.
