Women on Top

- According to Forbes 2010 most powerful women list, several of our favorite companies have women as their CEO’s.

- In January, President Obama signed the historic Lilly Ledbetter Fair Pay Act, which aims to guarantee equal compensation for men and women.

- Yet women still don't enjoy the same rewards for their managerial performance as men.

- This year, America's top-paid female CEOs earned, on average, $3.9 million. Compare this to the men, who raked in an average of $11.9 million.
