A change from straight-line depreciation to double-declining-balance depreciation would be reported as a restatement of the prior period statements only.
The term depreciation refers to an accounting technique used to spread the cost of a tangible or physical asset over its useful life. Depreciation indicates how much of an asset's value has been used. It allows companies to generate income from the assets they own by making payments over a period of time.
Depreciation expense is apportioned to charge a reasonable portion of the depreciation amount for each accounting period over the expected useful life of the asset. Depreciation includes the depreciation of assets with a predetermined useful life.
