Mayer left Google (GOOG) to join Yahoo (YHOO) as its CEO, president and a board member in July of 2012. Her base salary was set at $1 million with an annual bonus target set at $2 million a year.
Though she only took home $6 million last year, Mayer reached No. 2 on this list because she was also offered a one-time retention award when she was hired, consisting of stock grants that could total $30 million when they vest over the next five years.
