Those lines of business might include trading desks (trading everything from gold and copper to kilowatts), transportation (pipelines, railcars and tankers) and storage (warehousing) operations, mining operations, as well as production, refining, and raw and finished commodity distribution operations.

Okay, I'll tell... but you won't believe it.
