Pompey are counting the cost of their second-successive Fratton Park postponement.
But David Lampitt insists the loss of revenue to the club is 'negligible'.
The Blues' clash with Scunthorpe was called off early on Saturday morning after an inspection by match officials.
It follows the scrapping of the visit of Burnley on December 4 in similar circumstances after heavy snow.
That means Pompey have missed out on two crucial Fratton Park pay days during December.
Their last home fixture was as long ago as November 13, when Doncaster ran out 3-2 winners. As a result of Saturday's cancellation, they missed out on a scheduled 112,000 windfall from season ticket sales.
They have also had to pulp programmes already printed and throw away food.
But Lampitt is unconcerned over the losses incurred.
Pompey's chief executive said: 'It is just a timing difference in our cash flow, it will not have a massive impact.
'Looking at our position across the season, it will probably end up negligible.
'The frustration is a football one more than a financial one because we wanted to play the game.
'Obviously there is the cost of reprinting programmes, throwing away food and a few other bits and bobs.
'We were also entitled to receive money from Barclays under the terms of season ticket sales.
'We will probably get this money back in January or February instead rather than having it in December, so it's entirely down to timing.
'We will have another month when the match-day income will be high because we have played these extra games. It is swings and roundabouts.
'These recent cancellations are not going to make a huge difference to us in finance terms.'
Pompey have missed out on windfalls totalling around 224,000 for the two matches.
This is in respect of season ticket sales, which are drawn on a game-by-game basis from Barclays Bank following every home match.
At approximately 112,000-a-game, the club will not receive a penny until the fixtures are rearranged and played.
In the meantime, Lampitt insisted the decision to call off the match at 8.30am on Saturday morning was strictly down to the officials.
He added: 'The decision was the referee's and not a football club one.
'When the referee makes that call there is not an awful lot you can do about it.
'After two cracking away wins we were desperately keen to get the game on and the fact it didn't go ahead is disappointing for us and everyone involved at Pompey.
'If we had got decent results from the two recently-postponed matches we would be in good shape at the end of the year – and that's where we want to be.'
