For Valuation Only - FVO
  
You know how some bottles of ketchup say things like "not for resale." Or how you'll watch a 30-minute infomercial about a stock trading strategy guaranteed to make you enough money that you'll be able to buy a mansion staffed only by bikini models...only to have the program end with a disclaimer that reads "for entertainment purposes only."
For Valuation Only kind of works like that. It's a quote for a security that may not represent an actual inducement to buy. It's provided (usually by market makers) only as a form of information. It's used to determine the value of the security, but doesn't indicate that its really for sale.
The blue book value of your car could be considered a form of FVO pricing. It doesn't mean you'll get that amount when you sell your car...it just works to provide a general ballpark for valuation purposes.
