For the mandatory annual test of an indefinite-life intangible, the most recent detailed calculation of recoverable amount from a prior period may be reused in the current year only when all three conditions hold: where the asset is tested within its cash-generating unit, the unit's assets and liabilities have not significantly changed since that calculation; the calculation showed recoverable amount comfortably above carrying amount; and an analysis of events and changed circumstances since then shows the chance of recoverable amount now being below carrying amount is remote.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
