The figure was revealed by Rangers' finance director Brian Stockbridge 10 days after the club's annual accounts revealed its cash balance was £11m at June this year. Mr Stockbridge indicated April next year would be the low point, with "over a million" left, and an "optional unsecured facility provided should we need it".
The amount does not take into account revenue generated by Rangers Retail, which Mr Stockbridge said was ahead of budget. He made the remarks at a meeting with supporters' groups.
A Court of Session hearing on Monday will judge whether shareholders seeking the appointments of Paul Murray, Malcolm Murray, Scott Murdoch and Alex Wilson to the board will be allowed to include those nominations in the annual general meeting's agenda. The board blocked those nominations after claiming they were not made validly.
