Loan Loss Provision doesn't match available Yield Tokens

[0xSzeth]

The Loan Loss Provision for each pool (which is simply the negative surplus in each pool) does not match the available yield tokens for purchase. E.g., the aWBTC pool might have a -$500 surplus but only have $75 worth of Yield Tokens for sale. Why?

The leading theory is that there are deposits that have already mature but weren't funded and didn't generate enough interest to pay the fixed-rate promised on the deposit. We wouldn't sell a Yield Token in this case as the Yield Token buyer would incur an immediate 100% loss (assuming the deposit is withdrawn immediately). This would explain the difference in the original comment.

Action: check to see if this is actually the case or if this needs further investigating.
