Stock Options [Abstract] |
Share-Based Compensation | Share-Based Compensation We recognize share-based compensation expense over the service period during which the awards are expected to vest. Share-based compensation expense includes the estimated effects of forfeitures, which are adjusted over the requisite service period to the extent actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures are recognized in the period of change and will impact the amount of expense to be recognized in future periods. Determining the appropriate option pricing model, calculating the grant date fair value of share-based awards, and estimating forfeiture rates requires considerable judgment, including estimations of stock price volatility and the expected term of options granted. We use the Black-Scholes option pricing model to value employee stock options. We estimate stock price volatility based on daily averages of our common stock’s historical volatility over a term approximately equal to the estimated time period the grant will remain outstanding. The expected term of options and forfeiture rate assumptions are derived from historical data.
Employee Stock Purchase Plan | Employee Stock Purchase Plan Our Employee Stock Purchase Plan (“ESPP”) permits employees to purchase Photronics, Inc. common shares at 85% of the lower of the closing market price at the commencement or ending date of the Plan year (which is approximately one year from the commencement date). We recognize the ESPP expense over that same period. As of October 31, 2023, the maximum number of shares of common stock approved by our shareholders to be purchased under the ESPP was 1.85 million shares, of which approximately 1.6 million shares had been issued through October 31, 2023. As of October 31, 2023, there is no unrecognized compensation cost. As of October 31, 2022, there were less than 0.1 million shares with unrecognized compensation cost of less than $0.1 million that was recognized in fiscal year 2023.

Stock Options [Abstract] |
Share-Based Compensation | Restricted Stock Awards We periodically grant restricted stock awards, the restrictions on which typically lapse over a service period of one to four years. The fair values of the awards are determined on the date of grant, based on the closing stock price of our common stock.

Stock Options [Abstract] |
Share-Based Compensation | Stock Options Option awards generally vest in one to four years and have a ten-year contractual term. All incentive and non-qualified stock option grants must have an exercise price no less than the market value of the underlying common stock on the date of grant. The grant-date fair values of options are based on closing prices of our common stock on the dates of grant and are calculated using the Black-Scholes option pricing model. Expected volatility is based on the historical volatility of our common stock. We use historical option exercise behavior and employee termination data to estimate expected term, which represents the period of time that options granted are expected to remain outstanding. The risk-free rate of return for the estimated term of an option is based on the U.S. Treasury yield curve in effect at the date of grant.
