20. SEGMENT INFORMATION

The Company does not identify or allocate assets by operating segment, nor does the chief operating decision maker (“CODM”) evaluate operating segments using discrete as set information. The Company does not have inter-segment revenue, and, accordingly, there is none to be reported. The Company does not allocate gains and losses from interest and other income, or income taxes to operating segments. The accounting policies for segment reporting are the same as for the Company as a whole.

Revenues by geographic region are based on the location to which our products or services are delivered and were as follows:
