I just stumbled upon an Excel spreadsheet which summarizes the Section 18 (Emergency Exemption) pesticides used in the US over the past ten years. 
According to this analysis, beekeepers using Coumaphos (Checkmite) averted losses of nearly 200 million dollars to the bee industry every year, until 2008, when it the product was reclassified as PT. This indicates Permanent Threshold, which means that the difference between what was made and what might have been lost is moot, because the product's use is firmly in place. In other words, no difference is established between use and nonuse because it is assumed that the use of Coumaphos is now standard practice. This, despite the fact that Coumaphos is approved only "temporarily" under Section 18. The total amount of loss that was avoided by the honey industry attributed to the use of Coumaphos is set at 1.5 billion dollars -- from 1999 to 2007, when they stopped making this calculation. Obviously, they therefore assume that it is still in widespread use.
