A change in accounting principles, accounting estimates, or the reporting entity. A change in an accounting principle is a change in a method used, such as using a different depreciation method or switching from LIFO to FIFO. An example of an accounting estimate change could be the recalculation of machine's estimated life due to wear and tear.
However, to the extent that a change in an accounting estimate gives rise to changes in assets and liabilities, or relates to an item of equity, it is recognised by adjusting the carrying amount of the related asset, liability, or equity item in the period of the change.[IAS 8.37].f a change in accounting policy is required by a new IASB standard or interpretation, the change is accounted for as required by that new pronouncement or, if the new pronouncement does not include specific transition provisions, then the change in accounting policy is applied retrospectively. [IAS 8.19].
