I'm going to ask this question. It was brought to my attention by Mr. McTeague. The question is in relation to one of the charts of the regular gasoline pump price components and the four-week average, May 15 to June 5, 2007. The question is about refining and marketing costs and margins and why this particular element of the chart is not subdivided.
On June 11th, 2007. See this statement in context.
