Disaggregation of Revenue [Table Text Block]

Disaggregation of Revenues

Revenue is disaggregated by major product category and geography, as we believe these categories best depict how the nature, amount, timing, and uncertainty of our revenue and cash flows are affected by economic factors. The following table includes a reconciliation of the disaggregated revenue by reportable segments. Service revenues are not material and are not separately disclosed.
