This is only news because it has to do with a major tech company and not a minor one.
It's probably some of the google stocks the company had that's the stock bonus. Comparing to the income CEOs in the tech industry this is actually nothing special at all, unless we talk about major companies, like yahoo. Four of the lower CEOs at google got about 128 million this year.
CEOs of other major tech companies are billionaires in NETWORTH but at least they now the PR value of not giving their CEOs this much money. Examples of billionaires that have a relatively low pay, Sergei and Larry (1$), Steve Ballmer (1 million $) and the amazon CEO (about 50k $).
