Inventory Disclosure [Abstract]
Inventories	Inventories: Inventories are measured using the last-in, first-out (LIFO) method of valuation. The excess of current costs over our carrying value of inventories was approximately $39,975,000 and $35,326,000 at December 31, 2025 and 2024, respectively. The use of the LIFO valuation method as compared to the FIFO method had a negative impact on our cost of goods sold of approximately $4,649,000 in 2025 and a positive impact of approximately $807,000 in 2024. In 2024, LIFO inventory layers were liquidated. The effect of the liquidations, which are included in the preceding LIFO impact amount, decreased cost of goods sold by approximately $1,100,000 or $0.07 per diluted share in 2024. We believe this information is meaningful to the users of these consolidated financial statements for analyzing the effects of price changes, for better understanding our financial position and for comparing such effects with other companies.
