Rangers announced six-month losses of £2.6million for the second half of last year.
Among the report's details was the surprise that Rangers will have to hand Newcastle United £500,000 if they win promotion to the Premiership as part of the deal which saw them take five Magpies youngsters on loan in January.
It is the type of bill the cash-strapped Light Blues could do without but McCall - who still does not know if he will be in charge beyond the summer - is refusing to worry about it too much right now.
"I was really surprised," said McCall after being asked for his reaction to loan-deal agreement. "I was gobsmacked if I'm being honest.
"I was driving in the car when I heard it on the radio and I just thought: 'Woof'. But if that's the deal, that's the deal.
"But I've got enough on just concentrating on what's happening on the training ground and the pitch."
