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.
In the U.S. there are 100 pounds in the hundredweight, and in Britain there are 112 pounds in the hundredweight. This causes the actual weight of the ton to differ between countries. To distinguish between the two tons, the smaller U.S. ton is called short, while the larger British ton is called long. There is also an third type of ton called the metric ton, equal to 1000 kilograms, or approximately 2204 pounds.
