      (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.
