Twenty billion is a mighty big number. But if that's all BP has to pay, the oil giant may be getting off cheap.
BP will put the first $5 billion into the claim fund in the second half of the year. They'll pay for it by eliminating stock dividends to their shareholders. The company will add another $5 billion to the fund over the next three years.

Lipow tells CBS News correspondent Anthony Mason that BP produces two and half million barrels of oil everyday around the world.
"With prices at $75 a barrel, their profits are going to be close to $20 billion a year," Lipow says.
President Obama made a point of mentioning last night that BP has 18 billion barrels in reserve, enough to fuel the U.S. for 2.5 years.

Analysts caution that, even for a company as big as BP, $20 billion isn't small change.
"It'll cut into the meat and bone of the operation, but they're a long way from the point where they would need to file for bankruptcy," said Geoff Styles of GSW Strategy Group.
The company likes to use the tagline, "Beyond Petroleum." Whatever the ultimate cost of this disaster, it will be hard for the company to get beyond it.
