Portsmouth are not guaranteed FA Cup money now they have entered into administration.
The club are required to make a written request for prize money, broadcast fees and pool payments under FA rules, and their request would then be considered by the Professional Game Board.
Portsmouth hope to earn more than £1.2million if they beat Birmingham City on Saturday in the FA Cup quarter-finals.
That figure includes £360,000 for reaching the last four, £247,000 in live television revenue and approximately £168,000 as part of 40 per cent gate receipts.
Pompey could expect a further £450,000, even if they lose in the semis, but that payment would not be made until after the semi-final stage.
Even if Portsmouth lose to Birmingham on Saturday, the club would hope to raise at least £415,000, while extra revenue would be raised by an FA Cup replay.
But only when the Professional Game Board are satisfied with their written request, and they are comfortable where the money will go at the club, would they authorise any payments.
