The scale for the horizontal axis of the figures corresponds to the two-year marketing window, that is, from September 1st of the year previous to harvest through August 31st of the year after harvest. However, a few programs begin their marketing recommendations over a particular crop year earlier than September 1st , and in these cases, the figures start with a positive net percentage priced. Similarly, a few programs continue their marketing recommendations for a period longer than the end of the two-year marketing window. In these cases, the net amount priced at the end of the graph is less.
