1. I believe AK Steel will retain its brand and operate as a subsidiary of Cliffs. Even so, it could take a few months to get new signs made and installed while the virus has delayed things.
2. Bakken crude comes mainly from North Dakota, Montana, and the southern prairies of Canada. Oil sands crude is different and comes from Alberta, north of Edmonton. Both are competitively disadvantaged due to location, and the oil sands require costly processing to mine and refine for shipping. The Marathon refinery reconfigured and added equipment to more efficiently process heavy oil. But like any refinery, it can process most grades of oil - but will be more limited in what finished fuels it can produce and how profitably it can accomplish that.
