SEGMENTS

The Company aggregates its operating segments into three reportable segments, U.S. and Canada, International and Manufacturing / Wholesale. The Company fully allocates warehousing and distribution costs to its reportable segments. The Company's chief operating decision maker evaluates segment operating results based primarily on performance indicators, including revenue and operating income. Operating income of each reportable segment excludes certain items that are managed at the consolidated level, such as corporate costs. The Manufacturing / Wholesale segment manufactures and sells product to the U.S. and Canada and International segments at cost with a markup, which is eliminated at consolidation. In connection with the asset sale of Lucky Vitamin on September 30, 2017, their results are included within Other for applicable prior periods to ensure comparability.
