"Assumptions"
"Starting values are examples, not market benchmarks or payment quotes."
"Use one currency and a consistent before-tax basis. Work out taxes and program-specific adjustments separately."

"Result notes"
"Negative closing credit indicates an over-application or missing receipt to investigate."
"This does not determine forfeiture, expiry, transferability, gift-card law, or revenue recognition. Pending refunds require a separate hold on further use."
