REVENUE

A majority of our revenue is derived from sales of delivered logs and manufactured wood products. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2018, using the cumulative effect method. The adoption of the new revenue recognition guidance did not materially impact our Consolidated Statement of Operations, Consolidated Balance Sheet, or Consolidated Statement of Cash Flows.

PERFORMANCE OBLIGATIONS

A performance obligation, as defined in ASC Topic 606, is a promise in a contract to transfer a distinct good or service to a customer. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue at the point in time, or over the period, in which the performance obligation is satisfied.

Performance obligations associated with delivered log sales are typically satisfied when the logs are delivered to our customers’ mills or delivered to an ocean vessel in the case of export sales. Performance obligations associated with the sale of wood products are typically satisfied when the products are shipped. Customers are generally invoiced shortly after logs are delivered or after wood products are shipped, with payment generally due within a month or less of the invoice date. ASC Topic 606 requires entities to consider significant financing components of contracts with customers, though allows for the use of a practical expedient when the period between satisfaction of a performance obligation and payment receipt is one year or less. Given the nature of our revenue transactions, we have elected to utilize this practical expedient.

Performance obligations associated with real estate sales are generally met when placed into escrow and all conditions of closing have been satisfied.

CONTRACT ESTIMATES

Substantially all of the company’s performance obligations are satisfied as of a point in time. Therefore, there is little judgment in determining when control transfers for our business segments as described above.

The transaction price for log sales generally equals the amount billed to our customer for logs delivered during the accounting period. For the limited number of log sales subject to a long-term supply agreement, the transaction price is variable but is known at the time of billing. For wood products sales, the transaction price is generally the amount billed to the customer for the products shipped but may be reduced slightly for estimated cash discounts and rebates.

There are no significant contract estimates related to the real estate business.

CONTRACT BALANCES

In general, customers are billed and a receivable is recorded as we ship and/or deliver wood products and logs. We generally receive payment shortly after products have been received by our customers. Contract asset and liability balances are immaterial.

For real estate sales, the company receives the entire consideration in cash at closing.
