Segment Reporting [Abstract] |
Business and geographic segments | Note 2 – Business and geographic segments: We are organized into two operating segments based on the nature of the products offered. Our chief operating decision maker (“CODM”) is our Vice Chairman of the Board. Our CODM is responsible for determining how to allocate resources and assessing performance. The CODM evaluates segment performance based on segment operating income, which is defined as income before income taxes, exclusive of certain general corporate income and expense items (primarily interest income) and certain non-recurring items (such as gains or losses on the disposition of long-lived assets outside the ordinary course of business). The CODM considers current-period segment operating income compared to plan and prior-period on a monthly and/or quarterly basis for evaluating performance of each segment and making decisions about allocating capital and other resources. The accounting policies of the reportable operating segments are the same as those described in Note 1. Capital expenditures include additions to property and equipment. Our two reportable operating segments are Security Products and Marine Components. The Security Products segment, with a facility in South Carolina and a facility shared with Marine Components in Illinois, manufactures locking mechanisms and other security products for sale to the postal, transportation, office and institutional furniture, cabinetry, tool storage, healthcare and other industries. The Marine Components segment, with a facility in Wisconsin and a facility shared with Security Products in Illinois, manufactures and distributes wake enhancement systems, stainless steel exhaust systems, gauges, throttle controls, trim tabs and related hardware and accessories primarily for ski/wakeboard boats and performance boats. Segment assets are comprised of all assets attributable to the reportable segments. Corporate assets are not attributable to the operating segments and consist primarily of cash, cash equivalents, marketable securities and note receivable from affiliate. For geographic information, the point of origin (place of manufacture) for all net sales is the U.S., the point of destination for net sales is based on the location of the customer, and property and equipment are attributable to their physical location. Intersegment sales are not material. ​
