Notes to Financial Statements
Goodwill Disclosure [Text Block]	14. Goodwill At December 31, 2014, the Company’s Goodwill of $5.3 million related entirely to its Water Transmission Group reporting unit. GAAP requires that goodwill of a reporting unit shall be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Due to current Water Transmission market conditions, the Company determined that its Water Transmission Group goodwill may be impaired at June 30, 2015, and completed the first step of the two-step quantitative goodwill impairment test. In the first step, business enterprise value of the reporting unit was calculated by using a combination of income and market approaches, and compared to the carrying value. As the carrying value of the Water Transmission Group reporting unit exceeded the calculated enterprise value, the Company determined it was appropriate to proceed to the second step of the quantitative impairment test. As a result of the analysis performed to date, the Company’s best estimate of the ultimate result of the second step of the goodwill quantitative impairment test is that all of the Water Transmission Group goodwill will be impaired. Therefore, the Water Transmission Group goodwill was completely written off as of June 30, 2015. Any adjustment to that estimate upon completion of the measurement of the impairment loss will be recognized in the three month period ending September 30, 2015.
