Exemption from preparation of group accounts

Dear Chris, in my text book there is a list of requirements for Parent's being exempt from preparing consolidated statements: -the parent itsel is subsidiary -parent's debt or equity ubstruments are not traded in public market -parent did not file ints financial statements with securities comission... -ultimate parent produces consolidated statements Should these all be adhered in order not toprepare consolidation or if only one of several is met then it is enough for exemption ? Thank you.
