An employee stock option plan (ESOP) allows employees to purchase company shares at a predetermined price, as compensation and motivation. Employees must wait a vesting period before exercising their option. ESOP objectives include retention, compensation, ownership culture, and performance improvement. Coverage differs between industries, with IT companies offering ESOPs to more employees. Shares can be allotted directly or through a trust. Benefits include recruitment, tax savings, and alignment. Limitations include undiversified risk, share dilution, and cash requirements for retiring employees. Infosys and Airtel pioneered successful ESOP programs in India.
