When Facebook filed for its initial public offering, it revealed the pay of its top five executives. And it's a ton, relative to other companies'. As a percentage of income, the combined compensation of Facebook's fab five--$83 million--is four times that of Apple's top brass and 10 times that of Goldman Sachs' reviled bankers. And that doesn't include prior stock grants that will make CEO Mark Zuckerberg and COO Sheryl Sandberg billionaires after the IPO. Compensation consultant Frank Glassner says pay is often tied to potential but still thinks this seems outsize. "The IPO justifies the pay, but I hope it's a onetime scenario," he says.
