Markham Publishing pic sells books to book shops worth £200,000 Just before the accounting year end. The agreement is that any book not sold may be returned to the publisher. None are returned in this accounting year, but past experience is that about 10% will be returned next year. The right of return expires after two years. Is the revenue to be entered in this year’s Markham profit and loss account £200,000 or £180,000 or something else?
