The chief executive of Google and its parent company, Alphabet Inc., Sundar Pichai, could earn up to $692 million over the next three years under a new compensation plan disclosed to the U.S. Securities and Exchange Commission.

If approved, the package would make Pichai one of the highest-paid CEOs in the world.

According to the filing released on Friday, Pichai’s base salary will remain $2 million per year, totalling $6 million over three years.

The bulk of the compensation will come in the form of stock from Alphabet and shares from two of its subsidiaries, the autonomous vehicle company Waymo and drone delivery service Wing.

The SEC filing indicates Pichai could receive around $130 million in stock from Waymo and $45 million from Wing.

The final value of the package will depend on the performance of the shares and the dividends paid by Alphabet.

The document also states that if Pichai were dismissed, he would forfeit all stock options that had not yet become exercisable.

“Current and previous incentives in Mr. Pichai’s compensation have benefited Alphabet and its stockholders significantly,” the company said in the filing.
