It has been reported today that Mattrick will get a huge pay package for his services, with a base salary of $1 million, a sign-on cash bonus of $5 million and an annual bonus of $2 million.
Additionally, the exec will receive a stock grant of 9 million restricted shares that vest over the next three years. At Zynga's current share price, that stock is worth over $30 million. At the end of his first year with the company, Mattrick will also get another $11 million in shares (based on current valuation), taking his overall compensation package to $50 million.
If Zynga is satisfied with his performance this year, he will also be eligible for new stock valued at $7 million next year as a bonus/grant.
Mattrick formerly had high-ranking positions at EA before coming to Microsoft and taking the Xbox division into the black after years of operating losses.
