During 2010, the controller of the Ryel Company asked you to prepare correcting journal entries for the following three situations:
1. Machine A was purchased for $50,000 on January 1, 2005. Straight line depreciation has been recorded for five years, and the Accumulated Depreciation account has a balance of $25,000. The estimated residual value remains at $5,000, but the service life is now estimated to be one year longer than estimated originally.
2. Machine B was purchased for $40,000 on January 1, 2008. It had an estimated residual value of $5,000 and an estimated service life of 10 years. It has been depreciated under the double declining balance method for two years. Now, at the beginning of the third year, Ryel has decided to change to the straight-line method.
3. Machine C was purchased for $20,000 on January 1, 2009. Double-declining-balance depreciation has been recorded for one year. The estimated residual value of the machine is $2,000 and the estimated service life is five years. The computation of the depreciation erroneously included the estimated residual value.
Required
Prepare any necessary correcting journal entries for each situation. Also prepare the journal entry necessary for each situation to record the depreciation for 2010. (Assume that the debit is to Depreciation Expense.)
