unearned discount

1. A discount inappropriately taken by a customer when payment is made after the manufacturer's stated discount period has elapsed.

The company taking delivery of the merchandise does not pay for 15 days, but claims the discount anyway.
2. A secret discount offered to one or more customers without being offered to other customers.
3. For financial institutions, loan interest deducted in advance and not yet applied to income.
