Sorry, big bankers and other bigwigs in corporate America. Some companies may be deemed "too big to fail" in the government's eyes, but that doesn't mean shareholders won't give the top brass a big, fat F for failure if it's warranted. Case in point: a majority of Citigroup (NYSE: C) shareholders just voted against CEO Vikram Pandit's compensation package.

Oh, snap!

F is for FAIL
Citigroup conducted some damage control after the financial crisis and the "too big to fail" fiasco; Pandit took a much-publicized $1 salary. Still, signs lived on that humility in light of government bailout funds might be sorely lacking. For example, jaws dropped when Citigroup went through with the purchase of a $50 million corporate jet in 2009.

How soon they forget -- or at least, hope that shareholders will forget. Last year, Pandit's total compensation reached $15 million, including a bonus of about $5 million, not to mention a retention bonus of $10 million payable after 2013 if some squishy, non-financial elements of "performance" are met. While Pandit's raking in the millions, Citigroup's stock has fallen about 23% in the last year.

An even more damning fact than stock performance is that out of 19 banks, Citigroup was one of just four that failed the Federal Reserve's bank stress tests recently. Fortunately, the 55% of shareholders who voted against Pandit's pay package probably hadn't forgotten that very pertinent nugget of information.

GMI Ratings president and CEO Richard Bennett also reminded us in a post that Citigroup was part of a group of five banks that settled with the government for $25 billion, ending investigations into allegedly abusive mortgage practices.

GMI Ratings, which provides global corporate governance and environmental, social, and governance, or ESG, research, has given Citigroup a different kind of failing grade: It's dubbed the company's accounting as "very aggressive" and gives it an ESG rating of F.

More smackdowns ahead?
So far this proxy season, Citigroup's failed say-on-pay vote stands out, big-time, compared to other say-on-pay failures like those of lesser-known International Game Technology and Actuant.

Of course, the annual meeting season isn't over yet, either. Last November, GMI identified a long list of possible say-on-pay failures for 2012, including major companies like Safeway (NYSE: SWY), Pfizer (NYSE: PFE), and Amgen (Nasdaq: AMGN).

Why might some corporate managements and boards find their metaphorical buns particularly toasted in the proverbial hot seat? They gained less than 70% approval from their shareholders in last year's say-on-pay votes, putting them at risk for continued shareholder dissatisfaction with CEO pay versus company performance.

The possibility of say-on-pay defeats doesn't come out of left field, either. Safeway's doling out of discretionary bonuses, Pfizer's payments to departing CEO Jeffrey Kindler (apparently dreamed up on departure), and Amgen's 37% increase in CEO Kevin Sharer's pay despite the company's layoffs and share price decrease in 2010 add fuel to the idea that shareholders could deliver a failing grade to such companies' compensation schemes this year.

Safeway, Pfizer, and Amgen will hold their annual meetings on May 15, April 26, and May 23, respectively, for those following along at home.

Good news for shareholders
Shareholders delivering a major snubbing to a massive financial firm like Citigroup is the best news I've heard in a while. Shareholders are beginning to care, pushing for executive pay to be linked to true performance. Although say-on-pay votes are non-binding, such rejections send a powerful message, even to huge companies like Citigroup.

No company should ever have been too big to fail. Fortunately, shareholders are voicing opposition to compensation packages that, in a rational world, are too big to pass. That's good news for all investors; the true spirit of capitalism -- rewarding merit and instilling a fear of failure -- is reemerging in our marketplace.
