During the six months ended June 30, 2025, we completed a strategic acquisition in our Performance Coatings segment. This acquisition was accounted for as a business combination with aggregate consideration of $9 million, of which $6 million was paid, net of $1 million of cash acquired, during the six months ended June 30, 2025. The overall impacts to our unaudited condensed consolidated financial statements were not considered to be material. The fair value attributable to identifiable intangible assets was $5 million, comprised of customer relationship assets, which will be amortized over a weighted average term of approximately 10 years.
