Verify the 5- and 7-year property class percentages given in Table 9.2 by applying the 200% DB approach to a piece of equipment with a nominal value of $1,000. For the 7-year property class, in what year is the switch from 200% DB to Straight Line made based on the percentages in the Table 9.2. Only half of the first and last years are considered in the computations. This means that for a five-year class property, only half the 200% DB amount (40%/2 = 20%) is deducted.
