On December 31, 2012, before the books were closed, the management and accountants of Madrasa Inc. made the following determinations about three depreciable assets.

1. Depreciable asset A was purchased January 2, 2009. It originally cost $340,000 and, for depreciation purposes, the straight-line method was originally chosen. The asset was originally expected to be useful for 10 years and have a zero salvage value. In 2012, the decision was made to change the depreciation method from straight-line to sum-of-the-years digits, and the estimates relating to useful life and salvage value remained unchanged.

2. Depreciable asset B was purchased January 3, 2008. It originally cost $258,000 and, for depreciation purposes, the straight-line method was chosen. The asset was originally expected to be useful for 15 years and have a zero salvage value. In 2012, the decision was made to shorten the total life of this asset to 9 years and to estimate the salvage value at $3,000.

3. Depreciable asset C was purchased January 5, 2008. The assets original cost was $140,100, and this amount was entirely expensed in 2008. This particular asset has a 10-year useful life and no salvage value. The straight-line method was chosen for depreciation purposes.
