Concentration of Risk

18. Concentrations of Risk

Our Paper segment has had a long-standing commercial and contractual relationship with Office Depot, our largest customer in the paper business. This relationship exposes us to a significant concentration of business and financial risk. Our sales to Office Depot represented 7% of our total Company sales for both 2019 and 2018 and about 50% and 47% of our Paper segment sales revenue for those periods, respectively. At December 31, 2019 and 2018, we had $76.2 million and $66.7 million of accounts receivable due from Office Depot, respectively, which represents 9% and 7% of our total Company receivables, respectively.

In 2019, sales to Office Depot represented about 50% of our Paper segment sales. If these sales are reduced, we would need to find new customers. We may not be able to fully replace any lost sales, and any new sales may be at lower prices or higher costs. Any significant deterioration in the financial condition of Office Depot affecting its ability to pay or any other change that affects its willingness to purchase our products will harm our business and results of operations.

Labor

At December 31, 2019, we had approximately 15,500 employees and approximately 45% of these employees worked pursuant to collective bargaining agreements. Approximately 63% of our hourly employees are represented by unions. The majority of our unionized employees are represented by the United Steel Workers (USW), the International Brotherhood of Teamsters (IBT), the International Association of Machinists (IAM), and the Association of Western Pulp and Paper Workers (AWPPW). Approximately 9% of our employees work pursuant to collective bargaining agreements that will expire within the next twelve months.
