Trevor Birch has insisted PKF have not taken a penny out of Pompey.
The administrators have been at Fratton Park since the club entered administration on February 17.
Since then they have amassed fees of more than £700,000.
A creditors’ committee meeting on May 20 gave the authority for PKF to take the first £425,000 out of the club in its current state.
Regardless, Birch claims to date the administrators have taken no such action in the interests of not affecting Pompey’s recovery.
And the former Chelsea chief executive believes that will be the case until PKF can be sure the club is no longer under threat of liquidation and able to afford such a payment.
Birch said: ‘We have not taken any funds out of the club so far because the cash flow will not allow it.
‘From May 20 onwards we have been entitled to do so and were granted the authority for £425,000 -– but have not.
‘We are not drawing any funds. We have not had a penny and not put any invoices in.
‘There is not the money in the job to do it and we want to make sure the club has chance to survive.
‘There are costs so far but we have not drawn them in terms of funds.’
The current total for PKF fees is expected to be revealed at Monday’s creditors’ meeting.
Creditors will also be asked to vote on Portpin’s CVA proposals as they seek to seize ownership of the club for a third time.
Should the move be approved, there is a 28-day cooling period for a deal to be completed.
Pompey can then move out of administration.
The Pompey Supporters’ Trust have indicated they will also be making a bid within the next few weeks.
