The CPO board agreed to hold an EGM before being reappointed at this month's stormy annual general meeting at Stamford Bridge.
Shareholders in the company which owns the land beneath Chelsea's home ground forced CPO to investigate the sale of shares leading up to October's EGM, at which the club attempted to buy back the stadium freehold.
CPO chairman Steve Frankham said in a statement: "We intend holding that further general meeting in approximately three months.
"Before the meeting is convened, an investigation will be completed under the supervision of Gray Smith into the issue of excess shares last October and he will present fellow directors with recommendations as to what, if any, steps can be taken to mitigate the situation - including considering ideas raised at the AGM."
