Samsonite has reported an increase of 20.9 percent to US$21.8 million in the sales of Gregory Mountain Products for the first half of its financial year, ended June 30. Further expansion of the brand in Japan helped to drive a 17.6 percent currency-neutral increase. High Sierra, the more lifestyle-oriented brand of backpacks owned by the group, recorded a decline of 3.7 percent to $52.4 million, off by 2.7 percent in local currencies, due primarily to lower sales in the U.S. and Canada, which offset growth in Australia. With the strong dollar affecting tourism spending, the group's total revenues increased by only 1.1 percent to $1,209.5 million for the period, up by 4.1 percent in constant currencies. Adjusted operating earnings before amortization (Ebitda) went up by 0.2 percent to $190.3 million. Net earnings decreased by 11.6 percent to $92.5 million.
