Since taking charge three years ago, Rogge has been keen to make sure that the organisation and their affiliated international sports federations and national Olympic committees could survive if the event had to be cancelled. He said: "The Games are our sole source of income. I said at the beginning of September 2001, just before 9/11, that we needed to have reserves to allow us to work for four years if the Games were cancelled for any reason - earthquakes, terrorism, political issues, epidemic.
