Five offers have been made for an interest in either Birmingham City or parent company Birmingham International Holdings Limited (BIHL).
Ernst & Young, who are in effective control of BIHL, are assessing the bids in relation to the Championship club or its parent company.
A statement to the Hong Kong Stock Exchange read: "The receivers are currently exploring all strategic options, including a number of offers from parties expressing an interest in the company and/or Birmingham City PLC.
"Up to March 30, 2015 the receivers have received five indicative non-binding offers from independent third parties in relation to possible acquisition of an interest in the company and/or Birmingham City PLC.
"As at the date of this announcement, no formal agreement in relation to the indicative non-binding offers has been entered into and the indicative non-binding offers may or may not proceed and/or lead to any transaction in relation to the disposal of any part of the group's interests.''
Ernst & Young were asked to take control of BIHL in February to help stop the infighting between the board and this month started investigating the affairs of the company.
Employees Stephen Lui and David Yen Ching Wai were appointed chairman and chief executive respectively.
Peter Pannu, Birmingham's former acting chairman, was removed from the BIHL board along with Chan Shun Wah and seven other directors resigned.
Carson Yeung, Birmingham's former owner who bought the club in 2009, is currently serving six years in prison for money laundering.
The Football League has received assurances the club are in no financial danger, with Birmingham currently 15th in the Championship ahead of Friday's visit of Rotherham.
