equal to the life +1. For example, a drill has a life of 3 years and is 
purchased 3 months before the year end. The following time diagram 
shows that depreciation will occur over 4 calendar years.
Example 1: A property has just been purchased for $150,000. The purchase 
price is allocated between $25,000 for land and $125,000 for improvements 
(building). The remaining useful life of the building is agreed to be 25 years. 
There is no salvage value forecasted at the end of the useful life of the building. 
Thus, the depreciable value and book value is $125,000.
The building was acquired 4 months before the end of the year. Using 
straight-line depreciation, find the amount of depreciation and remaining 
depreciable value for the 1st, 2nd, 25th, and 26th years. What is the total 
depreciation after 3 years?
