NOTE 10—STOCK OPTION AND PURCHASE PLANS

The Company has stock option plans that authorize the issuance of options for shares of Common Stock to directors, officers and key employees. Stock option grants are designed to reward long-term contributions to the Company and provide incentives for recipients to remain with the Company. The exercise price, determined by a committee of the Board of Directors, may not be less than the fair market value of the Common Stock on the grant date. Options become exercisable over periods not exceeding ten years. The Company’s practice has been to issue new shares upon the exercise of the options.

Stock compensation expense recognized during the period is based on the value of the portion of share-based payment awards that is ultimately expected to vest during the period. Vesting requirements vary for directors, officers and key employees. In general, options granted to outside directors vest six months from the date of grant and options granted to officers and key employees straight line vest over a five-year period from the date of grant.

The weighted average fair value of the options was $17.46, $9.34 and, $3.58 for options granted during the year ended December 31, 2011, 2010 and 2009, respectively.

The weighted average fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions:

To determine expected volatility, the Company uses historical volatility based on weekly closing prices of its Common Stock and considers currently available information to determine if future volatility is expected to differ over the expected terms of the options granted. The risk-free rate is based on the United States Treasury yield curve at the time of grant for the appropriate term of the options granted. Expected dividends are based on the Company’s history and expectation of dividend payouts. The expected term of stock options is based on vesting schedules, expected exercise patterns and contractual terms.

The following table provides compensation expense information based on the fair value of stock options for the years ended December 31, 2011, 2010 and 2009:

The weighted average fair value of options vested during 2011, 2010 and 2009 was $4.89, $4.28 and $7.40, respectively. At December 31, 2011, total compensation costs related to non-vested awards not yet recognized amounts to $2.3 million and will be recognized over a weighted average period of 2.4 years.

The following is a summary of weighted average exercise prices and contractual lives for outstanding and exercisable stock options as of December 31, 2011:

The Company established Incentive Stock Option Plans for the purpose of attracting and retaining executive officers and key employees, and to align management’s interest with those of the shareholders. Generally, the options must be exercised within ten years from the grant date and vest ratably over a five-year period. The exercise price for the options is equal to the fair market value at the date of grant. At December 31, 2011, the Company had options outstanding for 1,006,799 shares under the plans. At December 31, 2011, there were 502,200 options available for future grant under the plan established in 2001.

The Company established the Directors Stock Option Plans for the purpose of attracting and retaining the services of experienced and knowledgeable outside directors, and to align their interest with those of the shareholders. The options must be exercised within ten years from the grant date. The exercise price for the option is equal to the fair market value at the date of grant and vests six months from the grant date. At December 31, 2011, the Company had options outstanding for 197,147 shares under the plans. At December 31, 2011, there were 133,518 options available for future grants under the plan established in 2006.

In addition to the options discussed above, the Company has established the Employee Stock Purchase Plan to encourage employees to invest in Astronics Corporation. The plan provides employees that have been with the Company for at least a year the opportunity to invest up to 20% of their cash compensation (up to an annual maximum of approximately $22,000) in Astronics common stock at a price equal to 85% of the fair market value of the Astronics common stock, determined each October 1. Employees are allowed to enroll annually. Employees indicate the number of shares they wish to obtain through the program and their intention to pay for the shares through payroll deductions over the annual cycle of October 1 through September 30. Employees can withdraw anytime during the annual cycle, and all money withheld from the employees pay is returned with interest. If an employee remains enrolled in the program, enough money will have been withheld from the employees’ pay during the year to pay for all the shares that the employee opted for under the program. At December 31, 2011, employees had subscribed to purchase 48,737 shares at $23.76 per share. The weighted average fair value of the options was approximately $5.46, $3.79 and $1.90 for options granted during the year ended December 31, 2011, 2010 and 2009, respectively.

The fair value for the options granted under the Employee Stock Purchase Plan was estimated at the date of grant using a Black- Scholes option pricing model with the following weighted-average assumptions:
