Strike Price: The fixed price at which you can purchase shares. Set at FMV on grant date. Lower strike = more profit potential.

409A Valuation: Independent appraisal determining FMV for private companies. Used to set strike prices for tax compliance.

Exercise Window: Time after leaving to exercise vested options. Standard is 90 days; some companies offer extended windows (1-10 years).

AMT (ISO): Alternative Minimum Tax may apply when exercising ISOs. The spread between strike and FMV at exercise is an AMT preference item.
