Disaggregation of Revenue

We disaggregate our revenue from contracts with customers by geographic region, end market, and timing of transfer of products and services to customers, 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. Disaggregated revenue is presented for each of our three reportable segments.
