Chief Financial Officer Luca Maestri's annual compensation rose about 81 percent to $25.3 million in 2015. In fact, Cook was the lowest-paid of the company's top executives. Angela Ahrendts, the senior vice president for retail and online stores, was the highest paid, with a total pay package of $25.8 million
Cook's base pay increased about 14.4 percent to $2 million last year, while non-equity incentive compensation rose about 19 percent to $8 million, according to a regulatory filing.
Apple had a good year for the most part under Cook. Sales in China in the most recent quarter nearly doubled from the same quarter in the prior year, for instance, and the iPhone continued to see record sales.
The company hit a rough patch towards the end of 2015, with shares falling about 4.6 percent for the year, the stock's first negative year since the global credit crisis.
As of September 26, Cook held about 3.1 million Apple shares that have not vested, potentially enabling him to earn over $310 million based on the stock's Wednesday closing price.
The shares are expected to vest between August 2016 and August 2021.
Shares of the world's most valuable company dropped below $100 for the first time in nearly five months on Wednesday before regaining some ground to close at $100.70.
