Receivables

12 Months Ended

Dec. 31, 2022

As of December 31, 2022, 38% of our net trade receivables were from customers in the United States and 11% were from customers in Mexico. As of December 31, 2021, 34% of our net trade receivables were from customers in the United States and 11% were from customers in Mexico. Receivables from our primary customer in Mexico accounted for approximately 9% and 10% of our total receivables as of December 31, 2022 and December 31, 2021, respectively. While we have experienced payment delays in Mexico, these amounts are not in dispute and we have not historically had, and we do not expect, any material write-offs due to collectability from this customer. No other country or single customer accounted for more than 10% of our receivables at those dates.

Although the market environment has been improving, we continue to have risk of delayed customer payments and payment defaults associated with customer liquidity issues. We routinely monitor the financial stability of our customers and employ an extensive process to evaluate the collectability of outstanding receivables. This process, which involves judgment and estimates, includes analysis of our customers’ historical time to pay, financial condition and various financial metrics, debt structure, credit ratings, and production profile, as well as political and economic factors in countries of operations and other customer-specific factors.
