STOCK-BASED COMPENSATION AND BENEFIT PLANS

STOCK-BASED COMPENSATION AND BENEFIT PLANS

Stock-based compensation plans

The Company's eligible employees participate in various stock-based compensation plans, which are provided by the Company directly.

Stock-based compensation expense charged to income for the plans was $24.9 million and $23.5 million for the two quarters ended August 2, 2020 and August 4, 2019, respectively. Total unrecognized compensation cost for all stock-based compensation plans was $95.5 million at August 2, 2020, which is expected to be recognized over a weighted-average period of 2.2 years.

A summary of the balances of the Company's stock-based compensation plans as of August 2, 2020, and changes during the first two quarters then ended, is presented below:

The grant date fair value of each stock option granted is estimated on the date of grant using the Black-Scholes model. The assumptions used to calculate the fair value of the options granted are evaluated and revised, as necessary, to reflect market conditions and the Company's historical experience. The expected term of the options is based upon the historical experience of similar awards, giving consideration to expectations of future employee behavior. Expected volatility is based upon the historical volatility of the Company's common stock for the period corresponding with the expected term of the options. The risk-free interest rate is based on the U.S. Treasury yield curve for the period corresponding with the expected term of the options. The following are weighted averages of the assumptions that were used in calculating the fair value of stock options granted during the first two quarters of fiscal 2020:

	Two Quarters Ended  August 2, 2020
Expected term	3.61 years
Expected volatility	40.03	%
Risk-free interest rate	0.32	%
Dividend yield	—	%

The Company's performance-based restricted stock units are awarded to eligible employees and entitle the grantee to receive a maximum of two shares of common stock per performance-based restricted stock unit if the Company achieves specified performance goals and the grantee remains employed during the vesting period. The fair value of performance-based restricted stock units is based on the closing price of the Company's common stock on the award date. Expense for performance-based restricted stock units is recognized when it is probable that the performance goal will be achieved.

The grant date fair value of the restricted shares and restricted stock units is based on the closing price of the Company's common stock on the award date. Restricted stock units that are settled in cash or common stock at the election of the employee are remeasured to fair value at the end of each reporting period until settlement. This fair value is based on the closing price of the Company's common stock on the last business day before each period end.

Employee share purchase plan

The Company's board of directors and stockholders approved the Company's Employee Share Purchase Plan ("ESPP") in September 2007. Contributions are made by eligible employees, subject to certain limits defined in the ESPP, and the Company matches one-third of the contribution. The maximum number of shares authorized to be purchased under the ESPP is 6.0 million shares. All shares purchased under the ESPP are purchased in the open market. During the quarter ended August 2, 2020, there were 14.9 thousand shares purchased.

Defined contribution pension plans

The Company offers defined contribution pension plans to its eligible employees. Participating employees may elect to defer and contribute a portion of their eligible compensation to a plan up to limits stated in the plan documents, not to exceed

the dollar amounts set by applicable laws. The Company matches 50% to 75% of the contribution depending on the participant's length of service, and the contribution is subject to a two year vesting period. The Company's net expense for the defined contribution plans was $4.5 million and $4.3 million in the first two quarters of fiscal 2020 and fiscal 2019, respectively.
