Segment Reporting, CODM, Profit (Loss) Measure, How Used, Description	Management measures the performance of each segment based on several metrics, including segment gross profit and segment contribution income (loss). Segment gross profit consists of segment net revenue less the related segment cost of revenue, where segment cost of revenue excludes stock-based compensation expense and amortization of intangible assets, each of which is managed at the corporate level and reported within unallocated indirect costs below. Segment contribution income (loss) consists of segment net revenue less the related segment cost of revenue, research and development and sales and marketing costs, in each case excluding the corporate-level items described below. Segment contribution income (loss) is used, in part, to evaluate the performance of, and allocate resources to, each of the segments. Certain operating expenses are not allocated to segments because they are separately managed at the corporate level.
