NEWMARKET CORP

3. Net Sales

Our revenues are predominantly derived from the manufacture and sale of petroleum additives products. We sell petroleum additives products across the world to customers located in the North America (the United States and Canada), Latin America (Mexico, Central America, and South America), Asia Pacific, and EMEAI (Europe/Middle East/Africa/India) regions. Our petroleum additives customers primarily consist of global, national, and independent oil companies. Our petroleum additives contracts generally include one performance obligation, which is satisfied at a point in time when products are shipped, delivered, or consumed by the customer, depending on the underlying contracts.

Additionally, we have revenue from the manufacture and sale of critical specialty materials products used primarily in solid rocket motors for space launch and military defense applications. The sale of specialty materials products is predominantly to customers located in the United States, with limited amounts to customers in other countries. Our specialty materials customers are primarily contractors or subcontractors of the U.S. government. Specialty materials contracts generally include one performance obligation, which is typically satisfied at a point in time when the products are shipped from the plant site.

In limited cases, we collect funds in advance of shipping product to our customers and recognizing the related revenue. These prepayments from customers are recorded as a contract liability until we ship the product and recognize the revenue. Some of our contracts include variable consideration in the form of rebates, tiered pricing, and/or business development funds. We regularly review these and make adjustments to estimated amounts when necessary, recognizing the full amount of any adjustment in the period identified.
