Share-Based Payment Arrangement [Abstract]  
Stock-based Compensation Stock-based Compensation
The Company issues equity awards to employees and non-employees in the form of stock options and restricted stock units (“RSUs”). Additionally, the Company also offers an employee stock purchase plan (“ESPP”) to its eligible employees. In the second quarter of 2022, the Company began to grant performance based RSU (“PRSU”) subject to performance and service vesting conditions. The Company uses Black-Scholes option pricing model to value its stock options granted and the estimated shares to be purchased under the ESPP. For both RSUs and PRSUs, the Company uses its common stock price, which is the last reported sales price on the grant date to value those securities.
In general, the Company recognizes its stock-based compensation expense on a straight-line basis over the requisite service period and records forfeitures as they occur. For PRSUs, the Company uses the graded vesting method to calculate
the stock-based compensation expense. At each reporting period, the Company would recognize and adjust the stock-based compensation expense based on its probability assessment in meeting its PRSUs' performance conditions.
The following table summarizes the total stock-based compensation expense, by operating expense category, recognized in the Condensed Consolidated Statements of Operations for the periods presented below (in thousands).

The aggregate intrinsic value of the stock options outstanding as of October 2, 2022 represents the value of the Company’s closing stock price at $18.34 on October 2, 2022 in excess of the exercise price multiplied by the number of options outstanding.
Unvested early exercised stock options which are subject to repurchase by the Company are not considered participating securities as those shares do not have non-forfeitable rights to dividends or dividend equivalents. Unvested early exercised stock options are not considered outstanding for purposes of the weighted average outstanding share calculation until they vest.
As of October 2, 2022, 3,342,128 shares remained subject to the Company’s right of repurchase as a result of early exercised stock options. The remaining liability related to early exercised shares as of October 2, 2022 was $0.2 million and was recorded in other current and non-current liabilities in the Condensed Consolidated Balance Sheets.
