[1] Our primary performance obligation is the distribution and sales of beverage products and food and snack products to our customers, each comprising approximately 50% of our consolidated net revenue. Internationally, our Latin America segment is predominantly a food and snack business, ESSA’s beverage business and food and snack business are each approximately 50% of the segment’s net revenue and AMENA’s beverage business and food and snack business are approximately 35% and 65%, respectively, of the segment’s net revenue. Beverage revenue from company-owned bottlers, which primarily includes our consolidated bottling operations in our NAB and ESSA segments, is approximately 40% of our consolidated net revenue. Generally, our finished goods beverage operations produce higher net revenue, but lower operating margins as compared to concentrate sold to authorized bottling partners for the manufacture of finished goods beverages. See Note 2 for additional information.
