REVENUE

14. REVENUE

We primarily offer the First DefenseÒ product line to dairy and beef producers to prevent scours in newborn calves. Generally, our products are promoted to veterinarians and dairy and beef producers by our sales team and then sold through distributors. Our primary market is North America. We do sell into select international regions and may expand this international reach in the future. There were no material changes between the allocation and timing of revenue recognition during the years ended December 31, 2019 or December 31, 2018 (under ASC 606). We do not have any contract assets such as contracts for which we have satisfied the performance obligations but do not yet have the right to bill for or contract liabilities such as customer advances. All trade receivables on our balance sheets are from contracts with customers. We incur no material costs to obtain contracts.
