A further clue
They filed "total exemption small" accounts, meaning they are exempt from audit.
That means they meet both the turnover and balance sheet criteria.
If for example they met the turnover and staff criteria, but not the balance sheet criteria, a common situation in property companies (big property asset, turnover is rent about 3% to 10% of the value of the property, 1 part time member of staff to bank the rent cheques and pay the mortgage), they would be able to file abbreviated accounts, but would have to have them audited.
Of course abbreviated accounts show the balance sheet and not much else, so you always know if they meet that criteria.
