Albatross Company purchased a piece of machinery for $51,000 on January 1, 2016, and has been depreciating the machine using the double-declining-balance method based on a five-year estimated useful life and no salvage value. On January 1, 2018, Albatross decided to switch to the straight-line method of depreciation. The salvage value is still zero and the estimated useful life did not change. Ignore income taxes.

Required:

1. Prepare the appropriate journal entry, if any, to record the accounting change under GAAP.

2. Prepare the journal entry to record depreciation for 2018.
