pre_text: (a) Revenue and Gross Margin by Segment We conduct business globally and are managed on a geographic basis consisting of three segments: the Americas, EMEA, and APJC. Our management makes financial decisions and allocates resources based on the information it receives from our internal management system. Sales are attributed to a segment based on the ordering location of the customer. We do not allocate research and development, sales and marketing, or general and administrative expenses to our segments in this internal management system because management does not include the information in our measurement of the performance of the operating segments. In addition, we do not allocate amortization and impairment of acquisition-related intangible assets, sharebased compensation expense, significant litigation settlements and other contingencies, charges related to asset impairments and restructurings, and certain other charges to the gross margin for each segment because management does not include this information in our measurement of the performance of the operating segments. Summarized financial information by segment for fiscal 2019, 2018, and 2017, based on our internal management system and as utilized by our Chief Operating Decision Maker (CODM), is as follows (in millions): Amounts may not sum and percentages may not recalculate due to rounding. Revenue in the United States was $27.4 billion, $25.5 billion, and $25.0 billion for fiscal 2019, 2018, and 2017, respectively.
