The Company generated strength in revenues in the First Aid business with improved margins. We increased market shares for both our Cuda fishing tools and Camillus hunting knives. The DMT sharpening business which we acquired in February 2016 exceeded our expectations, while our Canadian and European businesses delivered strong performances.”

Mr. Johnsen added, “We are entering 2017 with confidence. Our core businesses are doing well and growing. We acquired Spill Magic this month, which provides world-class fluid absorbent solutions for safety, and look forward to building its sales and earnings. For 2017, we are providing guidance of approximately $137 million in sales and net income of $6.7 million.”

In the Company’s U.S. segment, net sales for the quarter ended December 31, 2016 increased 13% compared to the same period in 2015 due to strong sales of Camillus knives, Cuda fishing tools, and first aid kits.

Net sales for the year ended December 31, 2016 grew 15% over the comparable period in 2015 due to strong sales of Westcott school and office products, Camillus knives, Cuda fishing tools and first aid products.

Net sales for the year ended December 31, 2016 increased 9% in both U.S. dollars and local currency.
