Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsAs previously disclosed, on January 25, 2016, the Company entered into a New Markets Tax Credit (“NMTC”) financing agreement to finance working capital improvements at its Monticello, Kentucky facility. The agreement was structured with unrelated third-party financial institutions (the “Investors”), their wholly-owned investment funds (the “Investment Funds”) and certain community development entities (the “CDEs”) in connection with our participation in qualified financing transactions under the NMTC program. In exchange for substantially all of the benefits derived from the tax credits, the Investors made a contribution of $2.3 million, net of syndication fees, to the Investment Funds. Simultaneously, a wholly-owned subsidiary of the Company made a $4.3 million loan to the Investment Funds. The Investment Funds used the proceeds of such equity and debt investments to acquire equity interests in the CDEs, which the CDEs in turn used to make loans to the Company aggregating $6.6 million for the project. These loans have terms of 30 years with an aggregate interest rate of approximately 1.2%. The original terms of the transaction included Investor put options, exercisable after 7 years, which, if exercised by the Investors, would require the Company to purchase the Investors’ interests in the Investment Funds. The Investors’ exercised such put options in February 2023 and we repurchased their interests in the Investment Funds in February 2023. The Company does not expect the impact of this transaction to have a material impact on its financial statements.
