The Depreciation Machine

Pick the method, respect its salvage rule, and prorate for time; DDB ignores salvage in the rate but never crosses it.

How the exam words it

The playbook

  1. 1Match the salvage rule to the method: straight line and SYD depreciate cost minus salvage; DDB applies 2/life to beginning book value and ignores salvage until book value would fall below it.
  2. 2Prorate the first year for a mid-year purchase, then roll each year's ending book value forward.
  3. 3For a disposal, bring accumulated depreciation up to the sale date, then gain or loss = proceeds minus book value.
  4. 4For impairment, test with undiscounted cash flows but measure the loss down to fair value.

The trap

Letting salvage into the DDB rate or applying the rate to original cost in later years. DDB uses beginning-of-year book value, and salvage only acts as a floor.
