In assessing the possibility that a reporting unit’s fair value has been reduced below its carrying amount due to the occurrence of events or circumstances between annual impairment testing dates, we consider all available evidence, including (i) the results of our impairment testing from the most recent testing date, (ii) downward revisions to internal forecasts or decreases in market multiples, if any, and (iii) declines in market capitalization. In the first quarter of 2021, we did not identify any reporting units that required an interim impairment test. However, we continue to monitor the operating results and cash flow forecasts of our Additive reporting unit in our Aviation segment as the fair value of this reporting unit was not significantly in excess of its carrying value. At March 31, 2021, our Additive reporting unit had goodwill of $236 million.

All other intangible assets of $9,395 million and $9,671 million at March 31, 2021 and December 31, 2020, respectively, are subject to amortization. Intangible assets decreased in the first quarter of 2021, primarily as a result of amortization. Consolidated amortization expense was $301 million and $318 million in the three months ended March 31, 2021 and 2020, respectively.
