Comments to Table A1-1

1. Shipments are from AHAM Fact Book. AHAM only collects shipment data on Standard 

Electric and Standard Gas vented residential clothes dryers. These are shown as All 

Electric and Gas. 

2. Members provided information on compact shipments, but this is a small market and 

aggregated data for both compact classes is not available. Therefore, compact shipments 

include shipments of both 120V and 240V vented residential dryers after 2003. These 

values are slightly different than those provided in August 2008, as I had not incorporated 

both classes into the total. 

3. The Standard column shows the difference between the aggregated member-supplied 

compact shipments (120 and 240V) and the All Electric published in the AHAM Fact 

Book. The source of and breakdown of the shipment information is slightly different, but 

we believe it is consistent. 

4. Aggregated shipment weighted average efficiencies are only available for 2005 and 2006 

for Standard Electric and Gas dryers. We did not receive enough input to provide data 

for years earlier than 2005 or for compact vented units.

Other Information: 1. What depreciation method would your company use to depreciate the conversion capital expenditures? _______________________________________________. Direct material – Costs of raw materials including scrap that can be traced to final or end products. Direct material costs do not include indirect material costs which arbe used in the production process but are not assigned to final products (e.g., lubricating oil for production machinery). 

Direct labor – The earnings of workers who assemble parts into a finished good for operate machines in the production process. Direct labor includes the fringe benefit

health care, as well as overtime pay. Direct labor does not include indirect labor which is defined as the earnings of employees who do not work directly in assembling a 

janitors, stockroom personnel, inspectors, and forklift operators. Overhead – Factory overhead excluding depreciation. Factory overhead includes indirect labor, downtime, set-up costs, indirect material, expendable tools, maintenanc
