C. REVENUE RECOGNITION

Revenue is recognized at the time the product is shipped to the customer. Generally, title passes at the time of shipment. In certain circumstances, the customer takes title when the shipment arrives at the destination. However, our shipping process is typically completed the same day.

Earnings on construction contracts are reflected in operations using percentage-of-completion accounting, under either cost to cost or units of delivery methods, depending on the nature of the business at individual operations. Under percentage-of-completion using the cost to cost method, revenues and related earnings on construction contracts are measured by the relationships of actual costs incurred related to the total estimated costs. Under percentage-of-completion using the units of delivery method, revenues and related earnings on construction contracts are measured by the relationships of actual units produced related to the total number of units. Revisions in earnings estimates on the construction contracts are recorded in the accounting period in which the basis for such revisions becomes known. Projected losses on individual contracts are charged to operations in their entirety when such losses become apparent. Construction contract revenue decreased to approximately $32.0 million, during the first quarter of 2017, from $32.5 million during the same period of 2016.

Our construction contracts are generally entered into with a fixed price and completion of the projects can range from 6 to 18 months in duration. Therefore, our operating results are impacted by, among many other things, labor rates and commodity costs. During the year, we update our estimated costs to complete our projects using current labor and commodity costs and recognize losses to the extent that they exist.

The following table presents the balances of percentage-of-completion accounts which are included in “Other current assets” and “Accrued liabilities: Other”, respectively (in thousands):
