Section 13: Investment Analysis 139
Example: An electron beam welder which costs $50,000 is purchased 4 months
before the end of the accounting year. What will the depreciation be during the
first full accounting year (year 2) if the welder has a 6 year depreciable life, a
salvage value of $8,000 and is depreciated using the declining-balance
depreciation method? The declining-balance factor is 150%.
