Preparing Entries for a Secured Borrowing and Subsequent Collections and Payments A note payable was executed by Sterling Inc. to Miami Finance Company. Sterling Inc. used $432,000 of its accounts receivable as collateral for the loan. The contract provided that Miami would advance 85% of the gross amount of the receivables. Sterling Inc. continues to collect payments for the receivables and the cash from customers is then remitted to the finance company. The cash remitted is first applied to the finance charges, with the remainder applied to principal. During the first month, customers owing $295,200 paid cash, less sales returns and allowances of $11,520, originally recorded as a refund liability. The finance charge at the end of the first month was $2,520. During the second month, the remaining receivables were collected in full, except for $2,880 off as uncollectible. Final settlement was effected with the finance company, including payment of an additional finance charge of $1,080. Cr. a. Record the entry for Sterling to record the secured borrowing.
