Under Mayer's employment agreement, she received a retention bonus of $15 million worth of Yahoo stock, $15 million in stock options based on performance and an additional $14 million in stock to make up for money she lost when she left competitor Google to transition to Yahoo.
Yahoo share prices have risen 46% since Mayer took the helm July, and the company reported higher earnings than expected for her first two quarters as CEO.
Mayer received a lot of press for announcing her pregnancy at the same time as her appointment to Yahoo. She gave birth in September and returned to work just two weeks later, saying that being a CEO with a baby is "easy."
Late last month Mayer was in the news again after ending work-from-home options for Yahoo employees. Long-distance employees who currently telecommute full-time will have to report to Yahoo offices starting in June.
