Over the last two years, Tata Consumer Products, Tata Power, Tata Communications, Titan and Tata Elxsi began offering performance-based stock units, restricted stock units and employee stock options (Esops) – all forms of equity-based compensation – for the first time. The latest is Tata Power, which sought shareholder approval to issue Esops this month. A top Tata group executive said instruments like Esops help companies to ensure their compensation packages are close to industry trends.
