In recent years Wang Company has purchased three machines. Because of frequent employee turnover in the accounting department, a different accountant was in charge of selecting the depreciation method for each machine, and various methods have been used. Information concerning the machines is summarized in the table below.

Machine Acquired Cost Salvage Value Useful Life (in years)Depreciation Method
1 Jan. 1, 2008 $96,000 $12,0006 Straight-line
2 July 1, 2009 85,000 10,0005 Declining-balance
3 Nov. 1, 2009 66,000 6,0006 Units-of-activity

For the declining-balance method, Wang Company uses the double-declining rate. For the units-of-activity method, total machine hours are expected to be 24,000. Actual hours of use in the first 3 years were: 2009, 400; 2010, 4,500; and 2011, 5,000.
