Munto Finance completed the buyout in July and has promised to invest millions of pounds into the club.
A statement from the Football League said: “This decision is based on the extensive disclosure provided by the club with regard to its ownership structure.
“Munto is a special-purpose acquisition company of a Middle East-backed investment fund based in Switzerland.”
The Football League statement continued: “This structure is complicated, and features both offshore entities and discretionary trusts.
“Together with the initial hesitation of the club’s ultimate owners to identify themselves, this made for a lengthy and at times difficult process.
“However, following greater co-operation from the club more recently, The League is now in a position to confirm that it is in possession of the appropriate details for those individuals that exercise control over the club.
“It is a matter for the club to determine what ownership information it makes public.”
