If SISU wish to remain as owners of Coventry City FC, they will have to name all their investors, it is understood.
The news comes as MP's led by Damian Collins have put before the football authorities new rules which will force clubs to admit who their owners and those who have an interest such as investors in them.
The football authorities have until the end of February to respond to the Government recommendations.
MP Damian Collins tweeted: "New rules should make ownership clear."
