3.    REVENUE

The following table presents our reportable segment revenues, disaggregated by revenue source. We disaggregate revenue from contracts with customers into major product lines. We have determined that disaggregating revenue into these categories depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

As noted in the segment reporting information in Note 19 below, our reportable segments are: Siding, OSB, EWP, and South America.

Revenue is recognized when obligations under the terms of a contract (i.e., purchase orders) with our customers are satisfied; generally, this occurs with the transfer of control of our products at a point in time. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. The shipping cost incurred by us to deliver products to our customers is recorded in cost of sales. The expected costs associated with our warranties continue to be recognized as an expense when the products are sold.

During 2021, 2020, and 2019, our top ten customers accounted for approximately 43%, 46%, and 42% of our sales, respectively, in the aggregate. No individual customer exceeded 10% of our sales in 2021, 2020, or 2019.

Our businesses routinely incur customer program costs to obtain favorable product placement, promote sales of products, and maintain competitive pricing. Customer program costs and incentives, including rebates and promotion and volume allowances, are accounted for as deductions from net sales at the time the program is initiated. These reductions from revenue are recorded at the time of sale or the implementation of the program based on management’s best estimates. Estimates are based on historical and projected experience for each type of program or customer. Volume allowances are accrued based on management’s estimation of customer volume achievement and other factors incorporated into customer agreements, such as new product purchases, store sell-through, and merchandising support. Management adjusts accruals when circumstances indicate (typically as a result of a change in volume expectations). As of December 31, 2021, and 2020, we accrued $45 million and $44 million, respectively, as customer rebates recorded in accounts payable and accrued liabilities on our Consolidated Balance Sheets.

We ship some of our products to customers' distribution centers on a consignment basis. We retain title to our products stored at the distribution centers. As our products are removed from the distribution centers by retailers and shipped to retailers’ stores, title passes from us to the retailers. At that time, we invoice the retailers and recognize revenue for these consignment transactions. We do not offer a right of return for products shipped to the retailers’ stores from the distribution centers. The amount of consignment inventory as of December 31, 2021 and 2020, was $2 million and $7 million, respectively.
