A claim against the debtor secured by collateral or by a right of setoff against the debtor. A secured creditor retains its prepetition lien or right of setoff notwithstanding the bankruptcy filing, and the debtor must provide adequate protection to the lender as a condition of using the lender’s collateral during the bankruptcy case. A Chapter 11 plan must provide for payment in full of all secured claims, with interest, as a condition of confirmation, and a secured creditor is entitled to credit bid if there is a sale of its collateral either during the case or under the plan.
