Segment Information

Segment Information

Note 12 – Segment information

We determine operating segments using the management approach. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the source of our operating segments. It also requires disclosures about products and services, geographic areas and major customers.

We have defined our operating segment based on geographic regions. We sell our products in three geographic regions. Our sales to these regions share similar economic characteristics, similar product mix, similar customers, and similar distribution methods. Accordingly, we have elected to aggregate these three geographic regions into a single operating segment. Revenue from the sale of our products which are similar in nature and software maintenance are reflected as total net sales in our Consolidated Statements of Income.

Total net sales, operating income, interest income and long-lived assets, classified by the major geographic areas in which we operate, are as follows (in thousands):
