Amounts represent sales to external customers. Sales are calculated after intersegment sales eliminations to our Building Materials Distribution segment, as well as the cost of EWP rebates and sales allowances provided at various stages of the supply chain (including distributors, retail lumberyards, and professional builders). Approximately 71% of Wood Products' EWP sales volumes were to our Building Materials Distribution segment.

As discussed in Note 3, Revenues, prior period amounts have not been adjusted under the modified retrospective method upon adoption of ASC Topic 606, Revenue from Contracts with Customers.
