NEW YORK (AP) — Profits at big U.S. companies broke records last year, and so did pay for CEOs.

The head of a typical public company made $9.6 million in 2011, according to an analysis by The Associated Press using data from Equilar, an executive pay research firm.

That was up more than 6 percent from the previous year, and is the second year in a row of increases. The figure is also the highest since the AP began tracking executive compensation in 2006.

Companies trimmed cash bonuses but handed out more in stock awards. For shareholder activists who have long decried CEO pay as exorbitant, that was a victory of sorts.

That's because the stock awards are being tied more often to company performance. In those instances, CEOs can't cash in the shares right away: They have to meet goals first, like boosting profit to a certain level.

The idea is to motivate CEOs to make sure a company does well and to tie their fortunes to the company's for the long term. For too long, activists say, CEOs have been richly rewarded no matter how a company has fared — "pay for pulse," as some critics call it.

To be sure, the companies' motives are pragmatic. The corporate world is under a brighter, more uncomfortable spotlight than it was a few years ago, before the financial crisis struck in the fall of 2008.

Last year, a law gave shareholders the right to vote on whether they approve of the CEO's pay. The vote is nonbinding, but companies are keen to avoid an embarrassing "no."

"I think the boards were more easily shamed than we thought they were," says Stephen Davis, a shareholder expert at Yale University, referring to boards of directors, which set executive pay.

In the past year, he says, "Shareholders found their voice."

The typical CEO got stock awards worth $3.6 million in 2011, up 11 percent from the year before. Cash bonuses fell about 7 percent, to $2 million.

The value of stock options, as determined by the company, climbed 6 percent to a median $1.7 million. Options usually give the CEO the right to buy shares in the future at the price they're trading at when the options are granted, so they're worth something only if the shares go up.

Profit at companies in the Standard & Poor's 500 stock index rose 16 percent last year, remarkable in an economy that grew more slowly than expected.

CEOs managed to sell more, and squeeze more profit from each sale, despite problems ranging from a downgrade of the U.S. credit rating to an economic slowdown in China and Europe's neverending debt crisis.

Still, there wasn't much immediate benefit for the shareholders. The S&P 500 ended the year unchanged from where it started. Including dividends, the index returned a slender 2 percent.

Shareholder activists, while glad that companies are moving a bigger portion of CEO pay into stock awards, caution that the rearranging isn't a cure-all.

For one thing, companies don't have to tie stock awards to performance. Instead, they can make the awards automatically payable on a certain date — meaning all the CEO has to do is stick around.

Other companies do tie stock awards to performance but set easy goals. Sometimes, "they set the bar so low, it would be difficult for an executive not to trip over it," says Patrick McGurn, special counsel at Institutional Shareholder Services, which advises pension funds and other big investors on how to vote.

And for many shareholders, their main concern — that pay is just too much, no matter what the form — has yet to be addressed.

"It's just that total (compensation) is going up, and that's where the problem lies," says Charles Elson, director of the Weinberg Center for Corporate Governance at the University of Delaware.

The typical American worker would have to labor for 244 years to make what the typical boss of a big public company makes in one. The median pay for U.S. workers was about $39,300 last year. That was up 1 percent from the year before, not enough to keep pace with inflation.

Since the AP began tracking CEO pay five years ago, the numbers have seesawed. Pay climbed in 2007, fell during the recession in 2008 and 2009 and then jumped again in 2010.

To determine 2011 pay packages, the AP used Equilar data to look at the 322 companies in the S&P 500 that had filed statements with federal regulators through April 30. To make comparisons fair, the sample includes only CEOs in place for at least two years.

Among the AP's other findings:

— David Simon, CEO of Simon Property, which operates malls around the country, is on track to be the highest-paid in the AP survey, at $137 million. That was almost entirely in stock awards that could eventually be worth $132 million. The company said it wanted to make sure Simon wasn't lured to another company. He has been CEO since 1995; his father and uncle are Simon Property's co-founders.

This month, Simon Property's shareholders rejected Simon's pay package by a large margin: 73 percent of the votes cast for or against were against.

But the company doesn't appear likely to change the 2011 package. After the shareholder vote, it released a statement saying that "we value our stockholders' input" and would "take their views into consideration as (the board) reviews compensation plans for our management team." But it also said that Simon's performance had been stellar and it needed to pay him enough to keep him in the job.

Simon's paycheck looks paltry compared with that of Apple CEO Tim Cook, whose pay package was valued at $378 million when he became CEO in August. That was almost entirely in stock awards, some of which won't be redeemable until 2021, so the value could change dramatically. Cook wasn't included in the AP study because he is new to the job.

— Of the five highest-paid CEOs, three were also in the top five the year before. All three are in the TV business: Leslie Moonves of CBS ($68 million); David Zaslav of Discovery Communications, parent of Animal Planet, TLC and other channels ($52 million); and Philippe Dauman of Viacom, which owns MTV and other channels ($43 million).

— About two in three CEOs got raises. For 16 CEOs in the sample, pay more than doubled from a year earlier, including Bank of America's Brian Moynihan (from $1.3 million to $7.5 million), Marathon Oil's Clarence Cazalot Jr. (from $8.8 million to $29.9 million) and Motorola Mobility's Sanjay Jha (from $13 million to $47.2 million).

— CEOs running health-care companies made the most ($10.8 million). Those running utilities made the least ($7 million).

— Perks and other personal benefits, such as hired drivers or personal use of company airplanes, rose only slightly, and some companies cut back, saying they wanted to align their pay structure with "best practices."

Military contractor General Dynamics stopped paying for country club memberships for top executives, though it gave them payments equivalent to three years of club fees to ease "transition issues" caused by the change.

The typical pay of $9.6 million that Equilar calculated is the median value, or the midpoint, of the companies used in the AP analysis. In other words, half the CEOs made more and half less.

To value stock awards and stock options, the AP used numbers supplied by the companies. Those figures are based on formulas the companies use to estimate what the stock and options will eventually be worth when a CEO receives the stock or cashes in the options.

Stock awards are generally valued based on the stock's current price. Stock options are valued using company estimates that take into account the stock's current price, how long until the CEO can cash the options in, how the stock price is expected to move before then, and expected dividends. Estimates don't generally take inflation into account.

The shift to stock awards is at least partly rooted in what is known as the Dodd-Frank law, passed in the wake of the financial crisis, which overhauled how banks and other public companies are regulated.

Beginning last year, Dodd-Frank required public companies to let shareholders vote on whether they approve of the top executives' pay packages. The votes are advisory, so companies don't have to take back even a penny if shareholders give them the thumbs-down. But shame has proved a powerful motivator.

It got Hewlett-Packard to change its ways. After an embarrassing "no" vote last year on the 2010 pay packages, including nearly $24 million for ousted CEO Mark Hurd, the company huddled with more than 200 investment firms and major shareholders, then threw out its old pay formula. New CEO Meg Whitman is getting $1 a year in salary and no guaranteed bonus for 2011. Nearly all her pay is in stock options that could be worth $16 million, but only if the share price goes up.

Other companies took notice, too. Last year, shareholders rejected the CEO pay packages at Janus Capital, homebuilder Beazer Homes and construction company Jacobs Engineering Group. All won approval this year after the companies made the packages more palatable to shareholders.

To be sure, shareholders aren't voting en masse against executive pay. Instead, they seem to be saving "no" votes for the executives they deem most egregious.

Of more than 3,000 U.S. companies that held votes in 2011, only 43 got rejections, according to ISS. But the mere presence of the "say on pay" vote is triggering change, shareholder activists say.

"Companies that have gone through that trial by fire don't want to go through it again," says McGurn, the ISS special counsel.

Even Chesapeake Energy, a company perennially in the cross-hairs of corporate-governance activists, is bowing to pressure. The company has drawn fire for showering CEO Aubrey McClendon with assorted goodies. In addition to handing him big pay packages — $17.9 million for 2011 — Chesapeake in recent years has spent millions sponsoring the NBA's Oklahoma City Thunder, which he partially owns, paying him for his collection of antique maps and letting him buy stakes in company wells.

Last year, shareholders of the natural gas producer passed the proposed 2010 pay package but by a low margin, 58 percent. This year, with shareholder pressure mounting, the board has ended some of McClendon's perks and stripped him of his title as chairman. A lawsuit settlement is forcing him to buy back his $12 million worth of maps.

After losing the chairman job, McClendon issued a statement saying the demotion "reflects our determination to uphold strong corporate governance standards." Chesapeake will seek shareholder approval for McClendon's 2011 pay at its annual meeting in June.

So far, Citigroup is the highest-profile company to have its pay package rejected this year. The bank planned to pay CEO Vikram Pandit about $15 million for his work last year, noting that he had returned the company to profitability in 2010 and worked for $1 that year. Shareholders, who watched the stock price plunge 44 percent in 2011 (after adjusting for a reverse stock split) weren't so forgiving.

It's usually around January that boards decide how much to pay a CEO for the previous year. Then they inform shareholders and ask for their vote in the spring — usually after the cash portion has already been handed out. For Pandit, that meant he had already received $7 million in salary and cash bonus by the time shareholders voted against his pay.

In a statement, Citi said it took the vote seriously and planned to "carefully consider" the input of major shareholders. It hasn't given more specifics. Richard Parsons, who retired as Citi's chairman after the April annual meeting, as previously planned, said after the vote that the board should have done a better job explaining to shareholders how it determined CEO pay.

Another big change is that more companies are giving themselves the right to take back a top executive's pay from previous years if they determine that the executive acted inappropriately to inflate the company's financial results.

The Dodd-Frank overhaul will eventually require public companies to include such broad "claw back" provisions, which will expand on narrowly written rules from a decade ago. But companies aren't waiting. In a separate study, Equilar found that 84 percent of Fortune 100 companies now include claw backs in their executive pay packages, up from 18 percent in 2006.

Last year, the former CEO of Beazer Homes agreed with regulators, who cited the older claw back rules, to turn over $6.5 million he had earned when profits were inflated. In February, UBS took back half of the previous year's bonuses awarded to many investment bankers because of subsequent losses in the unit.

Picking the right mix of incentives is partly just guesswork, and sometimes the results are simply a force of serendipity. Stocks can get swept up in rising or falling markets, so the fortunes of CEOs with well-designed pay packages can reflect luck — good or bad — not just managerial skills.

In February 2009, James Rohr, the head of PNC Financial Services, was granted options that allowed him to buy shares in the future at the then-current price, which had fallen 62 percent in five months on its way to a 17-year low the next month.

The stock has since doubled, and the options, mostly based on hitting certain profit and cost-cutting goals, are worth more than $20 million in paper profit, according to research by GMI Rating, a corporate governance watchdog. If investors had bought PNC stock just before the financial crisis in 2008, they would still be down more than a fifth.

Luck, of course, can cut both ways. Rohr is still waiting to cash in options granted in 2007, valued then at $2.5 million, when the stock was 18 percent higher than it is today.

Some shareholder groups doubt that ever-higher CEO pay, ingrained as it is in the corporate psyche, will ever be refashioned dramatically enough to satisfy shareholders and consumer groups who see the paychecks as too big, too disconnected from performance, and set by wealthy directors who are oblivious to the way that most of their shareholders live.

"I hope we have seen the last of this," says Rosanna Weaver of the CtW Investment Group, which works on shareholder issues with union-sponsored pension funds and has lobbied against CEO pay packages at a number of companies. "But I would be very surprised, just given what I know of human nature, let alone what I know of the financial markets."

Still, she's encouraged by the change that has already been stirred.

"It's a very big task," Weaver says. "I still believe it is worth trying."
