Because the equipment has a useful life of only five years, it is expected to lose value quickly in the first few years of use.

Double-Declining Balance (DDB) Depreciation Formula

Instead of multiplying by our fixed rate, we’ll link the end-of-period balance in Year 5 to our salvage value assumption. Since public companies are incentivized to increase shareholder value (and thus, their share price), it is often in their best interests to recognize depreciation more gradually using the straight-line method.
