A new sales representative, Mark Yount, has just received his copy of the month-end financial reports. He is puzzled by the term "unearned revenue." He left the following email message for you on the company's bulletin board system: What is this? Creative Accounting, or what? Line item 12 on year-to-date financials shows over $25Gs ($25,000) in Unearned Revenue! Come on, guys! Either we earned it, or we didn't . . . Right? Is this how you guys lower our commissions? Required: Write a response to send to Mark.
