13. SEASONALITY

The Company’s operating results have historically varied from quarter to quarter, often attributable to seasonal trends in the demand for Trex products. The Company has historically experienced lower net sales during the fourth quarter due to the holiday season. Also, seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift net sales to a later period.
