Final answer:
The main reason for using an accelerated depreciation method is to better match depreciation expenses with an asset’s revenue production and utility, often offering tax advantages and a more realistic portrayal of an asset’s value over time.
Step-by-step explanation:
The main reason for using an accelerated depreciation method is to match an asset's expense recognition with its usage patterns and to take larger depreciation deductions in the early years of an asset's life.
Companies often use accelerated depreciation methods such as the Double Declining Balance method or Sum-of-the-Years'-Digits method for tax advantages, as they can reduce taxable income more in the earlier years of an asset's life when it is more productive and generating more revenue. Additionally, accelerated depreciation can also portray a more accurate financial picture for assets that lose value quickly.
