It's not just Wells Fargo: executives who get the golden ax

It's the definition of "failing upwards." It's become almost rote that when executives resign in disgrace they get to walk away with massive paydays.

This time around, though, there may be some small measure of comeuppance after Wells Fargo CEO John Stumpf, under fire after his bank was caught creating 2 million accounts that may not have been authorized by customers in order to rack up fees, announced he will forfeit $41 million in stock awards.

Although Stumpf has yet to resign, the bank's independent board of directors is reportedly livid with his handling of the scandal — and the knives are clearly out.

The news comes a day before Stumpf was to testify to Congress, and a week after he was grilled in a Senate hearing on Wells Fargo's questionable cross-selling practices.

The move may be "more about optics than substance," according to Isaac Boltansky, an analyst at Compass Point Research & Trading, who told Bloomberg the clawback would do little to mollify irate lawmakers or their constituents. And it's only a portion of the total $200 million he stood to receive, should he resign in the fallout.

Executives who are shot out of the cannon after a crisis only to float down on a golden parachute galls the public's sense of righteous indignation, but experts say there are some very good business reasons for the robust severance pay.

"Taking a risk might be right for shareholders, but the CEO might not do it if it could cost him his job," Wharton finance professor Luke Taylor told a university publication. "Somehow, with this cushion, a CEO is willing take risks."

When a leader is nudged to walk the plank, it can "facilitate a smooth and efficient transition from the previous CEO to a new one," wrote Indiana University professors Eitan Goldman and Peggy Huang in a 2010 study. Their research found that prior to a CEO's exit, severance contracts were in place for only 13 percent of Fortune 500 top executives who stepped down between 1993 and 2007 — but 47 percent got a bonus when they left. In other words, some of these CEOs were encouraged to go quietly.
