Over the past 4 years, GOOG's net income and earnings per share have fallen quite a bit. Revenue has been pretty flat. I don't get why Pichai is so well paid. Ballmer actually did preside over some impressive growth when he was CEO of MSFT. Pichai has not.
Edit: I was looking at the wrong numbers. Google's profit has roughly quadrupled in the 8 years Pichai has been CEO. His compensation makes a lot more sense in that light.
