Long-Lived Asset Impairment | | To assess impairment, assets are grouped at the smallest levels for which there are separately identifiable cash inflows that are largely independent of the cash inflows from other assets or groups of assets (this can be at the asset or CGU level). At the end of each reporting period, we review conditions to determine whether there is any indication that an impairment exists that could potentially impact the carrying amounts of both our long-lived assets (including property, plant and equipment, and investments) to be held and used and our identifiable intangible assets and goodwill. When such indicators exist, impairment testing is performed. Regardless, goodwill is tested at least annually (in the fourth quarter). Where impairment indicators exist for the asset or CGU: • the recoverable amount is estimated (the higher of FVLCD and value in use); • to assess value in use, the estimated future cash flows are discounted to their present value (using apre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU for which the estimates of future cash flows have not been adjusted); • the impairment loss is the amount by which the carrying amount exceeds its recoverable amount; and | | Estimates and judgment involves: • identifying the appropriate asset or CGU; • determining the appropriate discount rate for assessing the recoverable amount; and • making assumptions about future sales, market conditions, terminal growth rates and cash flow forecasts over the long-term life of the assets or CGUs. We cannot predict if an event that triggers impairment will occur, when it will occur or how it will affect reported asset amounts. Asset impairment amounts previously recorded could be affected if different assumptions were used or if market and other conditions change. Such changes could result innon-cash charges materially affecting our consolidated financial statements. Impairments were recognized during 2019 and 2018 as shown in Note 15 and Note 16. At December 31, 2019, we reviewed our Phosphate CGUs for impairment triggers. For our Aurora CGU, we used judgment in assessing possible indicators of impairment including expected mine life, supply and demand variables and expected benchmark prices. Based on our assessment, there were no impairment triggers. For our White Springs CGU, we identified an impairment trigger due to deteriorating price expectations and the expected remaining mine life. We completed an impairment analysis and determined that there was no impairment in excess of the $250 impairment loss previously recorded at December 31, 2017. |
