| Tabular List [Table Text Block] | Most Important Measures to Determine CAP for the fiscal year ended October 31, 2023 As described in greater detail in the “Executive Compensation – Compensation Discussion and Analysis,” our executive compensation program is designed to reflect our variable “pay-for-performance” philosophy. The performance measures that we use for both our short-term and long-term incentive award programs are selected based on an objective of incentivizing Our CEO and our other NEOs to increase the value of our enterprise for our stockholders. The most important financial performance measures used by us to link executive compensation actually paid to our CEO and our other NEOs, for the most recently completed fiscal year, to our performance are as follows: • Non-GAAP EPS, • Non-GAAP Revenue Growth • Non-GAAP ARR Growth • Operating Margin • Relative TSR | ||||
