The replacement of an existing asset may be approved when the existing asset remains in use until the replacement is available for use. In these circumstances, depreciate the existing asset over its revised useful life, the period from replacement approval to replacement availability. For further guidance, see the example in FPM 20-25, "Impairment of Long-Lived Assets". If the replacement is subject to a CAR, the point of approval is upon approval of the CAR by the required Division and PepsiCo senior management.
