The problem is that there were large volume stock returned from big box retailers after the auditors signed-off the accounts from the previous year. The auditors only backed out sales returned from up to the date the auditors review the accounts (1 July to the day they signed the accounts in August), so this year they want to back out all unpaid orders but management disagreed, hence delayed. The auditors aren't at fault here as they wouldn't expect/know large orders were pushed out before year-end and returned to the company after the accounts were audited.
