They're looking at a likely $300+ billion in operating income over the next four quarters. $500m simply no longer matters. They'd be crazy not to spread that spigot of cash around.

There isn't anything else to do with that much cash other than attempt to buy up the industry (they won't be allowed) or dump it back to shareholders (they don't want to).
