Oracle's credit rating is hovering just above junk bond level. I think the capital agreements are similar to an Adjustable Rate Mortgage and monthly so if there's another rate increase from the Fed and Oracle can't find anyone to buy their bonds and/or their free cash flow continues to be negative then maybe that is a pin-prick in the stock bubble? Its sort of like if you keep bouncing around from 0% credit card offer for 12 months to another and then you stop getting 0% offers, then its time to face the music (those usually have a 3% transaction fee, at least a long time ago they did).
