On the first part with respect to nobody having opinions on it, I'd like to clarify. I don't have an opinion because I'm not the person who knows the differential. There may be people with an organization or company, etc., who do have that knowledge, but I don't personally.
With respect to the agency setting the rates on an annual basis, I think that is valuable because of the volatility of costs, etc. We're not working in a static environment, things do change, and I think that ought to be taken into account so that all players are competitive. For the railways, the cost of their operations ought to be properly reflected, as with shipper costs. Having that done in a transparent, timely, regular fashion, I think is beneficial.
