Accounting Changes [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Changes in Accounting Policies The Company adopted Topic 606, effective January 1, 2018, using the modified retrospective method, applying Topic 606 to contracts that are not complete as of the date of initial application. Under the modified retrospective method, the cumulative effect of applying the standard has been recognized at the date of initial application, January 1, 2018. The comparative information has not been adjusted and continues to be reported under Topic 605. The Company's accounting policy has been updated to align with Topic 606, and no significant changes to revenue recognition have occurred as a result of the change. Shipping and handling charges are not considered a separate performance obligation. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities must be accrued. Additionally, all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer (e.g., sales, use, value added, and some excise taxes) are excluded from revenue. The Company's policy elections related to shipping and handling and taxes have not changed with the adoption of Topic 606. Under Topic 605, revenue was generally recognized when all of the following criteria were met: a) persuasive evidence of an arrangement exists, b) price is fixed or determinable, c) collectability is reasonably assured and d) delivery has occurred or services have been rendered. The majority of the Company's revenue is generated through the manufacture and sale of a broad range of specialized products and components and revenue was recognized upon transfer of title and risk of loss, which was generally upon shipment. In limited cases, the Company's revenue arrangements with customers required delivery, installation, testing, certification, or other acceptance provisions to be satisfied before revenue was recognized. The Company included shipping costs billed to customers in Revenue and the related shipping costs in Cost of goods and services. Impact on Financial Statements The adoption of Topic 606 impacted certain contracts for highly customized customer products that have no alternative use and in which the contract specifies the Company has a right to payment for its costs, plus a reasonable margin. For these contracts, the Company now recognizes revenue over time based on the method and measure of progress that best depicts the transfer of control to the customer of the goods or services to date relative to the remaining goods or services promised under the contract. The Company recorded a cumulative catch-up adjustment to retained earnings at January 1, 2018 for $0.2 million, related to the impact of adopting Topic 606 under the modified retrospective method. The impact of adopting Topic 606 was not material to the Company’s consolidated financial statements as of and for the three and six months ended June 30, 2018.
