Individual workers' wages are recorded on the DES wage record files and retained for five quarters to be used for determining monetary benefit entitlement should a worker file a claim for unemployment insurance benefits. The DES is required to establish and maintain a separate experience rate account for each employer.
In the United States and formerly Canada a ton is defined to be 2,000 pounds (907 kg). Where confusion is possible, the 2240 lb ton is called long ton and the 2000 lb ton short ton; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.
One long ton is equal to 2,240 pounds (1,016 kg), 12% larger than a short ton and 1.6% larger than the 1,000-kilogram (2,205 lb) tonne, or 35 cubic feet (0.9911 m 3) of salt water with a density of 64 lb/cu ft (1.025 g/ml).
