The correct answer is option G: "B and C."
Lindy's, Inc. would need to disclose the new depreciation amount for the asset and the reason for the change in estimated life and residual value (Option B). This is because a change in depreciation estimates, especially if material, should be disclosed in the financial statements.
Additionally, Lindy's would need to disclose the effect of the change in life and residual value on depreciation expense in 2021 if the amount is material (Option C). This disclosure helps provide transparency about the impact of the change in estimates on the company's financial results.
Option D is not relevant in this context as it refers to per-share amounts, which are typically disclosed in the context of stock splits or stock dividends and not related to changes in depreciation estimates.
