Zynga Now Worth Less Than Its Own Office Building [Halting Problem]

How does that work? If it has $1.5 billion in cash, surely it's not "worth" just $500 million, then anyone would go buy it and take their cash.
Now suppose the piggy bank is actually a soda bottle. Returning the bottle to the store gets you five cents, plus the ten dollar bill is still inside, so the combination is worth $10.05 when broken up, but only $10.01 when together. Thus the bottle-bank has a negative value.
This might be because a bottle-bank is slimy and disgusting. Read whatever you will into this analogy :-)
How much is just the wallet worth?
If I pay $2B for Zynga and then pay myself back $1.5B from its cash reserve then it has only cost me $0.5B to buy. Hence its net worth is $0.5B.
