Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instrument Risk	Financial Instrument Risk In the normal course of business, we are exposed to financial risks such as changes in commodity prices, interest rates, and foreign currency exchange rates. In 2022, 2021, and 2020, we did not use derivative instruments to manage these risks, except for interest rate swaps as discussed below. Commodity Price Risk Many of the products we manufacture or purchase and resell and some of our key production inputs are commodities whose price is determined by the market's supply and demand for such products. Price fluctuations in our selling prices and key costs have a significant effect on our financial performance. The markets for most of these commodities are cyclical and are primarily affected by economic uncertainties, industry operating rates, transportation constraints or disruptions, net import and export activity, inventory levels in various distribution channels, and seasonal demand patterns. Interest Rate Risk We are exposed to interest rate risk arising from fluctuations in variable-rate SOFR on our term loan and when we have loan amounts outstanding on our Revolving Credit Facility. At December 31, 2022, we had $50.0 million of variable-rate debt outstanding based on one-month term SOFR. Our objective is to limit the variability of interest payments on our debt. To meet this objective, we enter into receive-variable, pay-fixed interest rate swaps to mitigate the variable-rate cash flow exposure with fixed-rate cash flows. In accordance with our risk management strategy, we actively monitor our interest rate exposure and use derivative instruments from time to time to manage the related risk. We do not speculate using derivative instruments. At December 31, 2022, we had one interest rate swap agreement. Under the interest rate swap, we receive one-month SOFR plus a spread adjustment of 0.10% variable interest rate payments and make fixed interest rate payments, thereby fixing the interest rate on $50.0 million of variable rate debt exposure. Payments on this interest rate swap, with a notional principal amount of $50.0 million, are due on a monthly basis at an annual fixed rate of 0.41%, and this swap expires in June 2025. We entered into this forward interest rate swap in 2020 (the 2020 Swap) and it was amended in September 2022. Prior to the amendment we received one-month LIBOR-based variable interest rate payments and made fixed interest rate payments at an annual fixed rate of 0.39% on the 2020 Swap. At December 31, 2021, we had two interest rate swap agreements. Under these interest rate swaps, we received one-month LIBOR-based variable interest rate payments and made fixed interest rate payments. Payments on one interest rate swap, entered into in 2016, with a notional principal amount of $50.0 million were due on a monthly basis at an annual fixed rate of 1.007%, and this swap expired in February 2022 (the Initial Swap). The 2020 Swap, as mentioned above, commenced on the expiration of the Initial Swap in February 2022. The interest rate swap agreements were not designated as cash flow hedges, and as a result, all changes in the fair value are recognized in "Change in fair value of interest rate swaps" in our Consolidated Statements of Operations rather than through other comprehensive income. At December 31, 2022, we recorded a long-term asset of $4.8 million in "Other assets" on our Consolidated Balance Sheets, representing the fair value of the interest rate swap agreement. At December 31, 2021, we recorded a long-term asset of $1.2 million in "Other assets" on our Consolidated Balance Sheets, and we also recorded a long-term liability of $0.1 million in "Other long-term liabilities" on our Consolidated Balance Sheets, representing the fair value of the interest rate swap agreements. The swaps were valued based on observable inputs for similar assets and liabilities and other observable inputs for interest rates and yield curves (Level 2 inputs). Foreign Currency Risk We have sales in countries outside the U.S. As a result, we are exposed to movements in foreign currency exchange rates, primarily in Canada, but we do not believe our exposure to currency fluctuations is significant.
