At December 31, 2024, the Company has $5.4 billion of goodwill and $1.5 billion of indefinite-lived intangible assets recorded on its balance sheet. We test goodwill and indefinite-lived intangibles for impairment at least annually and more frequently if the Company believes indicators of impairment exist. The valuation models used to determine the fair value of goodwill or indefinite-lived intangible assets are dependent upon various assumptions and reflect management's best estimates.
The goodwill and indefinite-lived intangible asset impairment analyses are sensitive to changes in key assumptions used, such as discount rate, revenue growth rate, tax rate, cash flow projections and terminal value rate. Such key assumptions may be adversely impacted by significant negative industry or economic trends and forecasts, disruptions to our business, inability to effectively integrate acquired businesses, unexpected significant change or planned changes in use of our assets, changes in the structure of our business, divestitures, or market capitalization declines. Changes in market conditions or key assumptions made in future quantitative tests could negatively impact the results of future impairment testing for any of the Company's reporting units and could result in the recognition of an impairment charge. Because of the significance of our goodwill and indefinite-lived intangible assets, any future impairment of these assets could require material noncash impairment losses, which also could be material to our statements of operations.
During the three months ended December 31, 2024, we recognized a non-cash goodwill impairment loss of $1.5 billion in our Engineered Materials segment. Additionally, we recognized aggregate non-cash impairment losses of $117 million for the year ended December 31, 2024 related to certain trade names, primarily Zytel®, included in the Engineered Materials segment. See Note 9 - Goodwill and Intangible Assets, Net in the accompanying consolidated financial statements for further information.
There can be no assurance that future events or conditions may not result in additional impairments in our engineered materials reporting unit or impairment to any of our other reporting units' goodwill or to any of our indefinite-lived intangible or long-lived assets.
