I think fair value is estimated for reporting Unit ( GAAP ) or cash-generating unit ( IFRS ) . Then impairment is 1-step in IFRS if carrying value
2-Step in GAAP if carrying value of reporting unit less than fair value of reporting unit , then estimate fair value of assets ( PPE ) also , then new GoodWill is fair value of reporting unit - fair value of assets in reportingunit. If this number is zero or negative , nothing further needs to be done ( GAAP).
