The Company also announced on February 18, 2022 that its Board of Directors has approved the divestiture of the Delrin® acetal homopolymer (H-POM) business. In addition to the entry into definitive agreements, the Company anticipates that the closing of the sale of Delrin® would be subject to regulatory approvals and other customary closing conditions, (the "Delrin® Divestiture" and together with the M&M Divestiture, the "M&M Divestitures").

The Retained Businesses are reported in Corporate & Other. The reporting changes have been retrospectively applied for all periods presented.
