Segment Reporting [Abstract]

Segments

12. Segments

We operate as a single operating and reportable segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker ("CODM") in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer. The CODM evaluates financial performance and allocates resources based on consolidated results, including consolidated net income. The total assets of the segment are reported on the Consolidated Balance Sheets.

The following table presents revenue, significant expenses, and consolidated net income for our reportable segment:
