⁽¹⁾The intrinsic value is calculated as the difference between the exercise price of the underlying stock option award and the closing market price of our common stock as of July 31, 2020.

During the six months ended July 31, 2020 and 2019, upon each settlement date of our outstanding RSUs to current employees, RSUs were withheld to cover the required withholding tax, which was based on the value of the RSU on the settlement date as determined by the closing price of our common stock on the trading day of the applicable settlement date. The remaining shares were delivered to the recipient as shares of our common stock. The amount remitted to the tax authorities for the employees’ tax obligation was reflected as a financing activity on our condensed consolidated statements of cash flows. These shares withheld by us as a result of the net settlement of RSUs were not considered issued and outstanding, thereby reducing our shares outstanding used to calculate earnings per share. These shares were returned to the reserves and are available for future issuance under our 2012 Equity Incentive Plan.

During the six months ended July 31, 2020, we granted 318,514 PSUs to certain executives under our 2012 Equity Incentive Plan, which includes both PSUs awarded but not yet earned, as well as PSUs earned and eligible to vest. The number of PSUs earned and eligible to vest will be determined after a one-year performance period, based on achievement of certain company financial performance measures and the recipient’s continued service with us. The number of shares of our stock to be received based on financial performance measures can range from 0% to 200% of the target amount. Compensation expense for PSUs with financial performance measures is measured using the fair value at the date of grant and recorded over the four-year vesting period under the graded-vesting attribution method, and may be adjusted over the vesting period based on interim estimates of performance against the pre-set objectives. Additionally, beginning in fiscal 2019, our PSUs granted contain an additional market performance measure that can increase the number of shares earned by up to an additional 50% of the shares received based on the financial performance measure.

The following table presents unrecognized compensation cost related to stock options, RSUs, PSUs and RSAs as of July 31, 2020:

PSUs	76,358		1.3
