In Lesson 6, you looked-up some cash prices at various hubs in the US using the link for Natural Gas Intelligence,
"http://intelligencepress.com/features/intcx/gas/ [1]". Using those same cash hubs, compare the most recent prices to the NYMEX Settlement price for natural gas for December, 2012. Use the CME website to find the most recent Settlement price.
Calculate the difference as follows: Cash price minus NYMEX. Post your answers on the course blog. These results represent what is known as the "actual Basis" relationship between the NYMEX Henry Hub contract and other physical delivery points in the US.
