During 2013, Ryel Company's controller asked you to prepare correcting journal entries for the following three situations:

1. Machine A was purchased for $50,000 on January 1, 2008. Straight-line depreciation has been recorded for 5 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 1 year longer than estimated originally.

2. Machine B was purchased for $40,000 on January 1, 2011. 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 2 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, 2012. Double-declining-balance depreciation has been recorded for 1 year. The estimated residual value of the machine is $2,000 and the estimated service life is 5 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 2013. (Assume that the debit is to Depreciation Expense.)
