Disaggregation of Revenues

In the following table, 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 table also includes a reconciliation of the disaggregated revenue with reportable segments.
