Advanced Manufacturing Production Tax Credits [Text Block]	NOTE 5 — AMP CREDITS During the first quarter of 2023, the Company recognized Advanced Manufacturing Production tax credits (“AMP credits”) totaling $3,162 within the Heavy Fabrications segment. These AMP credits were introduced as part of the Inflation Reduction Act (“IRA”) which was enacted on August 16, 2022. The IRA includes advanced manufacturing tax credits for manufacturers of eligible components, including wind and solar components. Manufacturers of wind components qualify for the AMP credits based on the total rated capacity, expressed on a per watt basis, of the completed wind turbine for which such component is designed. The credit applies to each component produced and sold in the U.S. starting in 2023 through 2032. Wind towers within the Company’s Heavy Fabrications segment are eligible for credits of $0.03 per watt for each wind tower produced. In calculating the eligible credit, the Company relied on the megawatt rating provided by the customer. Manufacturers can apply to the Internal Revenue Service for cash refunds of the AMP credits for up to five years. After the first five years, the AMP credits are transferable and can be sold to third parties for cash. The Company recognized the AMP credits as a reduction to cost of sales in the Company’s condensed consolidated statements of operations for the three months ended March 31, 2023. The assets related to the AMP credits are recognized as a long-term asset in the “AMP credit receivable” line item in the Company's condensed consolidated balance sheets as of March 31, 2023. There are currently several critical and complex aspects of the IRA pending technical guidance and regulations from the Internal Revenue Service and the U.S. Treasury Department. Any modifications to the law or its effects arising, for example, through technical guidance and regulations from the Internal Revenue Service and the U.S. Treasury Department could result in changes to the expected and/or actual benefits in the future, which could have a material effect on the Company, results of operations, financial performance and future development efforts.
