Final answer:
The alternative depreciation system is not used for calculating the AMT adjustment.
Step-by-step explanation:
The statement is false. The alternative depreciation system (ADS) is actually used to calculate depreciation deductions for assets used in business or income-producing activities. It is not specifically related to the alternative minimum tax (AMT) adjustment. The AMT adjustment is a separate calculation that determines the difference between regular tax calculations and the AMT tax calculations.
