Acquisitions	Acquisitions Centralsul Acquisition - On May 8, 2024, the Company acquired all the outstanding shares of Centralsul Ltda. (Centralsul), an auto appearance and fragrance manufacturer and distributor based in Southern Brazil (Centralsul Acquisition), which is expected to increase the Company's Auto Care presence in the region. The share purchase agreement (SPA) included a contractual purchase price of approximately $15, which was adjusted by Centralsul's outstanding debt, an indemnity holdback and working capital adjustments resulting in an initial cash payment of $10.6. The Company finalized the working capital adjustment in the first fiscal quarter of 2025 and paid an additional $0.1. The indemnity holdback is approximately $2 and will be used to satisfy any indemnification claims or paid out over a contractual timeline through 2027. The SPA includes a potential earnout payment of up to approximately $5 if certain financial metrics are achieved during calendar year 2025. If achieved, the earnout will be paid in the second fiscal quarter of 2026. The preliminary purchase price of the acquisition including the estimated earnout is $16.5. The Company has allocated the preliminary purchase price to the assets acquired and liabilities assumed, and has preliminarily recognized goodwill of $14.6, which is attributable to the workforce of the acquired business and the established distribution footprint of the Centralsul business in the region. This goodwill has been allocated to the Auto Care segment and is not deductible for tax purposes.
