Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

We are organized based on geographical location. We conduct our business through three reportable segments: the Americas, EMEA and APAC.

We evaluate segment performance based primarily on segment income from operations. Each segment reports its results of operations and makes requests for capital expenditures and working capital needs to our chief operating decision-maker (CODM). Our Chief Executive Officer serves as our CODM.

The following tables present operating and financial information by business segment (in thousands):
