“Debt” is defined in paragraph (12) [enacted as (11)] as a liability on a claim. The terms “debt” and “claim” are coextensive: a creditor has a “claim” against the debtor; the debtor owes a “debt” to the creditor. This definition of “debt” and the definition of “claim” on which it is based, proposed 11 U.S.C. 101 (4), does not include a transaction such as a policy loan on an insurance policy. Under that kind of transaction, the debtor is not liable to the insurance company for repayment; the amount owed is merely available to the company for setoff against any benefits that become payable under the policy. As such, the loan is not a claim (it is not a right to payment) that the company can assert against the estate; nor is the debtor’s obligation a debt (a liability on a claim) that will be discharged under proposed 11 U.S.C. 523 or 524.
