Who are the top 10 highest-paid female CEOs?

Marissa Mayer of Yahoo was the highest-paid female CEO in 2014, according to a new executive compensation study.

Female CEOs are outpacing male colleagues in pay, although they remain vastly outnumbered in the top echelons of U.S. companies.

Last year, the median pay for women CEOs rose to $15.9 million, a 21 percent gain from a year earlier, according to a study by executive compensation data firm Equilar and The Associated Press. That compared with median pay for male CEOs of $10.4 million, which was down 0.8 percent from 2013.

Marissa Mayer, the head of Yahoo, was the highest-paid female chief executive in the Equilar/AP pay study.

Still, there is a caveat: There are far fewer female CEOs than males among large U.S companies. The study of 340 CEOs included 17 women.

No. 1: Marissa Mayer, Yahoo, $42.1 million, up 69 percent

Yahoo’s stock price has climbed about 177 percent since the technology company hired Mayer from Google in July 2012. That compares with a gain of 76 percent for the tech- focused Nasdaq over the same time. Earnings jumped at Yahoo last year.

No. 2: Carol Meyrowitz, TJX Companies, $23.3 million, up 13 percent

Meyrowitz has led the parent company of T.J. Maxx, Marshalls and other stores since January 2007. For the year that ended in January, the company reported profit of $2.22 billion on revenue of $29.08 billion. The company said in February that it would lift hourly wages for its employees.

No. 3: Margaret Whitman, Hewlett-Packard, $19.6 million, up 11 percent

When Whitman rejoined HP in 2011, the company’s board established an initial salary of $1 a year. For 2014, the board raised the salary portion of her pay package to make it consistent with her peers at similar tech companies. Her base salary increased to $1.5 million.

No. 4: Indra Nooyi, PepsiCo, $19.1 million, up 45 percent

PepsiCo., which makes Frito- Lay snacks, Gatorade and Qua-ker oatmeal, has improved its performance by raising prices and slashing costs. The company’s earnings were hit this year by currency volatility in countries like Russia and Bolivia, but this was offset by growth at Frito-Lay North America, which makes snacks such as Doritos and Cheetos.

No. 5: Phebe Novakovic, General Dynamics, $19 million, up 1 percent

Novakovic was a senior executive at General Dynamics for more than a decade before she was promoted to the top job in January 2013. Since she took the position, the defense contractor’s stock has doubled as it has increased dividend payouts and boosted stock buybacks.

No. 6: Virginia Rometty, IBM, $17.9 million, up 28 percent

The IBM boss was awarded a $3.6 million bonus for her performance last year, even though the company’s sales and profits declined. Her overall pay jumped from 2013, when Rometty and other top executives did not take bonuses.

No. 7: Marillyn Hewson, Lockheed Martin, $17.9 million, up 13 percent

Hewson is a 32-year veteran at Lockheed Martin and the second CEO at a defense company to top the list of best-paid female CEOs. Her pay award increased as the company’s earnings rose. Lockheed’s stock also gained nearly 30 percent.

No. 8: Patricia Woertz, Archer Daniels Midland, $16.3 million, up 138 percent

Woertz’s near nine-year tenure as CEO of Archer Daniels Midland ended in December, though she still holds the position of chairman at the company, which makes vegetable oil, ethanol and ingredients used in packaged foods and drinks. Her compensation included $501,560 for relocation expenses after ADM moved its global headquarters to Chicago from Decatur, Ill.

No. 9: Irene Rosenfeld, Mondelez International, $15.9 million, up 14 percent

The maker of Oreo cookies, Cadbury chocolate and Trident gum raised Rosenfeld’s overall pay by 14 percent last year. Shareholders didn’t fare as well. The company’s stock rose 3 percent, compared with a gain of 11.4 percent for the broader stock market.

No. 10: Ellen Kullman, DuPont, $13.1 million, down 1 percent

Kullman spent much of last year fending off an attempt by activist investor Nelson Peltz to gain more influence over the 212-year-old chemical company. She prevailed in May this year after shareholders voted against his campaign. But the fight showed DuPont needed to do a better job of explaining its transformation from a traditional chemical maker to a growing company focused on agricultural products and advanced materials such as Kevlar, which it makes at a plant near Goose Creek.
