From here on, it is just arithmetic: 830,000 barrels per day equals 303,000,000 barrels per year. If Koch gets 1/18 of that capacity, it is 16.8 million barrels per year. IFG says Koch *only* needs to sell eight billion barrels to break even on the $120 billion it will lose (over 50 years) because of the pipeline. So how long will it take Koch to break even? Eight billion divided by 16.8 million = 476 years. Yup! In a mere 476 years, Koch will break even on the Keystone pipeline!
