The company hired Morgan Stanley CFO Porat as its finance chief earlier this week, a sign it is aiming to rein in costs as it invests in new businesses such as self-driving cars and Internet-connected eyeglasses. Porat’s compensation package includes a grant of $25 million through restricted stock units, a $40 million biennial grant in 2016 and a special one-time $5 million sign-on bonus, Google said in a regulatory filing on Thursday. Porat, who will join Google on May 26, will also get an annual base salary of $650,000.
