The introduction to EW's Market Planning Guide (November, 2007, p. 26) contained an error explaining the methodology used by DISC Corp., Orange, Conn., in its annual sales forecasts. The article incorrectly stated that DISC reports its sales forecasts in deflated dollars, when in fact its sales forecasts have always used current dollar sales and do contain inflation.

The DISC numbers are in the same measurements as the EW numbers (inflated dollars), but not the same growth rates. The difference in growth rates is not because of inflation but because EW does a survey of what distributors think will happen, while DISC develops its forecast by analyzing performance of the economic indicators that directly impact electrical distributor industry sales.
