Most of Ellison's pay ($90.7 million) comes from his stock grants. In June of 2011 he was given an option to purchase 7 million shares of Oracle(ORCL) common stock.
Total compensation is calculated as the sum of base salary, discretionary and performance-based cash bonuses, the grant-date fair value of stock and option awards during the fiscal year, and other compensation like benefits and perks. Equilar, an executive compensation research firm, prepared the data by looking at CEOs of technology companies that filed proxies by June 3, 2013. See more on Larry Ellison from Equilar.
