Based on the information from the Air Canada 2015 Annual Report shown below, identify differences between the accounting for PPE using IFRS (used by Air Canada) and ASPE (as shown in the chapter). Create a chart, and list each asset and its accounting treatment. Summary of Significant Accounting Policies-Section T, Property and Equipment Property and equipment is recognized using the cost model. . . . The Corporation allocates the amount initially recognized in respect of an item of property and equipment to its significant components and depreciates separately each component. Property and equipment are depreciated to estimated residual values based on the straight-line method over their estimated service lives. Aircraft and flight equipment are componentized into airframe, engine, and cabin interior equipment and modifications. Airframes and engines are depreciated over 20 to 25 years, with 10% to 20% estimated residual values. Spare engines and related parts ("rotables") are depreciated over the average remaining useful life of the fleet to which they relate with 10% to 20% estimated residual values. Cabin interior equipment and modifications to aircraft on operating leases are amortized over the term of the lease. Major maintenance of airframes and engines, including replacement spares and parts, labour costs, and/or third party maintenance service costs, are capitalized and amortized over the average expected life between major maintenance events. Major maintenance events typically consist of more complex inspections and servicing of the aircraft.
