At the beginning of $2023,$ a decision was made to adopt the straight$-$line method of depreciation for this machinery to better match expenses to their related revenues. Depreciation for $2023,$ based on the straight$-$line method, was included in selling, general, and administrative expenses. $($Hint: A change in depreciation method is considered a change in estimate, not a change in accounting policy.$)$ Grouper Ltd$.$ Combined Statement of Income and Retained Earnings $\backslash$$ $\backslash (\backslash$square $\backslash )\backslash$$
