The IOC said last month it would offer financial assistance to Vancouver's organising committee (VANOC) if it ends up with a budget gap following the Games next February.
"We are optimistic together with VANOC that there will be no deficit," Rogge told The Associated Press. "However, if you want to manage carefully, you have to account for all possibilities. In case there would be a deficit ... the IOC would agree to participate in the deficit together with the other stakeholders."
"Don't ask me precise figures. I think we have to discuss with them when the situation arises. There is a willingness to support in part the deficit."
VANOC has a shortfall of up to $37 million on its $1.75 billion operating budget.
