   (a)      List total amount of claims even if under secured.

   (b)      Estimated amount of claim to be allowed after compromise or
            litigation. As an example, you are a defendant in a lawsuit
            alleging damage of $10,000,000 and a proof of claim is
            filed in that amount. You believe that you can settle the
            case for a claim of $3,000,000. For Schedule E reporting
            purposes you should list $10,000,000 as the Claimed Amount
            and $3,000,000 as the Allowed Amount.
