ARM 42.22.1308. DEPRECIATION SCHEDULES

(1) Depreciation schedules for all property, other than land or improvements to land, shall be published annually by the department.

These depreciation rates will normally compensate for the loss in value due to ordinary wear and tear, offset by reasonable maintenance, and ordinary functional obsolescence due to technological changes within the process during the life expectancy period.
