Answer: $220,000
Step-by-step explanation:
Using the Accrual Method of Accounting means that revenue is only to be recorded when it is earned i.e. when services have been delivered.
Any revenue received when the services have not been delivered will be recorded as Unearned Revenue.
With $528,000 in subscription revenue, the monthly subscription is;
= 528,000/12
= $44,000
From June to December would be 7 months so they would have earned;
= 44,000 * 7
= $308,000
The amount that they have not earned but have received would therefore be;
= 528,000 - 308,000
= $220,000
This amount will be recorded after they finish deliveries of magazines in next year May.
