Re: Valid reason for the chargeCve said they would need to spend this amount about every 5 years..........lets assume the refinery has a lifespan of 50 years ......so that is 10 times what they spebd this year plus inflation.........this would theoretically cause the current value of this asset to be impaired by that amount......presumably $1.9 billion.........but the taxes saved by this impairment will be huge over time
