Write a paragraph to explain why unearned revenues are liabilities rather than revenues. In your explanation, use the following actual example: Maclean's magazine collects cash from subscribers in advance and later mails the magazines to subscribers over a one-year period. Explain what happens to the unearned subscription revenue over the course of a year as the magazines are mailed to subscribers. Into what other account does the unearned subscription revenue go? Give the adjusting entry that Maclean's would make to record earning $75,000 of subscription revenue. Include an explanation for the entry.
