Segment Reporting [Abstract]

Business segment information

Note 2 – Business segment information:

Our chief operating decision maker (“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).

Intersegment sales are not material. Our CODM is not regularly provided financial information related to the assets of the reportable segments, including capital expenditures, and he does not evaluate their performance or allocate resources to them based on assets. Therefore, total assets by reportable segment are not included in our segment disclosure.
