We monitor our reporting units for indicators of impairment throughout the year to determine if a change in facts or circumstances warrants a re-evaluation of our goodwill. We have not recorded any goodwill impairments for the three months ended March 31, 2023. (1) As discussed in Note 2, we recast our segment presentation to present our Heatcraft Worldwide Refrigeration business as a component of our Commercial segment and our European portfolio as a component of Corporate & Other. Since there is no longer a Refrigeration segment, we allocated goodwill to each segment based upon the relative fair value of the business.
