The South Korea race, first run in 2010, returned operating losses of 39.4 billion won (£23 million), race organisers said.
One of nine Asian races on the 20-stop 2012 Formula One calendar, including the Asia-Pacific Australian Grand Prix, the South Korean event also lost an estimated £30m-plus in its first year.
