In the fourth quarter of 2022, an indefinite-lived tradename used by our Insulation segment was partially impaired. A change in the estimated long-term revenue growth rate or discount rate for our Insulation segment could increase the likelihood of a future impairment.

As a result of this test, we determined that no impairment existed for the tradename.Fair value used in testing for potential impairment of our tradename was calculated using the relief-from-royalty method by applying an estimated market value royalty rate to the forecasted revenues of the businesses that utilize that asset
