Note 2. Stock Based Compensation

Stock-Based Compensation: The Company’s stock-based compensation plans are administered by the Compensation Committee of the board of directors, which selects persons to receive awards and determines the number of shares subject to each award and the terms, conditions, performance measures and other provisions of the award.

On February 23, 2023, the Company’s shareholders approved the Clearfield, Inc. 2022 Stock Compensation Plan (the “2022 Plan”). The 2022 Plan became effective on the date of shareholder approval, and no further awards may be made under the Clearfield, Inc. Amended and Restated 2007 Stock Compensation Plan (the “Prior Plan”) following the effective date of the 2022 Plan. The total number of shares of stock reserved and available for distribution under the 2022 Plan upon approval was 1,461,461 shares, which includes the number of shares remaining for grant and delivery under the Prior Plan, plus any shares subject to outstanding awards under the Prior Plan as of the effective date of the 2022 Plan that were forfeited, cancelled, or settled for cash.

As of September 30, 2023, $4,445,000 of total unrecognized compensation expense related to non-vested awards is expected to be recognized over a period of approximately 2.9 years. The Company recorded related compensation expense for the years ended September 30, 2023, 2022, and 2021 of $3,578,000, $2,339,000, and $1,280,000, respectively. For the year ended September 30, 2023, $3,407,000 of this expense was included in selling, general and administrative expense and $171,000 was included in cost of sales. For the year ended September 30, 2022, $2,213,000 of this expense was included in selling, general and administrative expense and $126,000 was included in cost of sales. For the year ended September 30, 2021, $1,223,000 of this expense was included in selling, general and administrative expense and $57,000 was included in cost of sales.

Stock Options: The Company uses the Black-Scholes option pricing model to determine the fair value of options granted. During the fiscal year ended September 30, 2023, the Company granted employees non-qualified stock options to purchase an aggregate of 40,266 shares of common stock with a weighted average contractual term of five years, a weighted average three-year vesting term, and a weighted average exercise price of $64.38. During the fiscal year ended September 30, 2022, the Company granted employees non-qualified stock options to purchase an aggregate of 62,730 shares of common stock with a weighted average contractual term of five years, a weighted average three-year vesting term, and a weighted average exercise price of $66.48. During the fiscal year ended September 30, 2021, the Company granted employees non-qualified stock options to purchase an aggregate of 105,089 shares of common stock with a weighted average contractual term of 5 years, a 3-year weighted average vesting term, and an exercise price of $23.74.

The fair value of stock option awards during the year ended September 30, 2023, 2022, and 2021 was estimated as of the respective grant dates using the assumptions listed below:

The expected stock price volatility is based on the historical volatility of the Company’s stock for a period approximating the expected life. The expected life represents the period of time that options are expected to be outstanding after their grant date. The risk-free interest rate reflects the interest rate at grant date on zero-coupon U.S. governmental bonds having a remaining life similar to the expected option term.

Options are generally granted at fair market values determined on the date of grant and vesting normally occurs over a three to five-year period. The maximum contractual term is normally six years. Shares issued upon exercise of a stock option are issued from the Company’s authorized but unissued shares. There were 79,911 options vested during the year ended September 30, 2023, 113,727 options vested during the year ended September 30, 2022, and 79,833 options vested during the year ended September 30, 2021. For the year ended September 30, 2023, there were 21,630 stock options that were exercised using a cashless method of exercise. For the year ended September 30, 2022, there were 125,651 stock options that were exercised using a cashless method of exercise. For the year ended September 30, 2021, there were 101,966 stock options that were exercised using a cashless method of exercise. The intrinsic value of options exercised during the years ended September 30, 2023, 2022, and 2021 was $1,603,000, $11,279,000, and $1,315,000 respectively.
