Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

12) Segment Information

There are four reportable segments: agricultural products, pressurized vessels, modular buildings and tools. The agricultural products segment fabricates and sells farming products as well as related equipment and replacement parts for these products in the United States and worldwide. The pressurized vessels segment produces and services pressurized tanks. The modular buildings segment manufactures and installs modular buildings for animal containment and various laboratory uses. The tools segment manufactures steel cutting tools and inserts.

The accounting policies applied to determine the segment information are the same as those described in the summary of significant accounting policies. Management evaluates the performance of each segment based on profit or loss from operations before income taxes, exclusive of nonrecurring gains and losses.

Approximate financial information with respect to the reportable segments is as follows.
