NOTE 18 -FAIR VALUE MEASUREMENTS

Fair Value Measurements on a Recurring Basis

The following tables summarize the basis used to measure certain assets and liabilities at fair value on a recurring basis:

1. Time deposits included in "Cash and cash equivalents" in the interim Condensed Consolidated Balance Sheets are held at amortized cost, which approximates fair value. "Restricted cash and cash equivalents" in the interim Condensed Consolidated Balance Sheets of $42 million at June 30, 2026 and December 31, 2025 are deposited in money market funds and represent Level 1 fair value measurement investments which are held at amortized cost.

2. See Note 17 for the classification of derivatives in the interim Condensed Consolidated Balance Sheets.

3. Asset and liability derivatives subject to an enforceable master netting arrangement with the same counterparty are presented on a net basis in the interim Condensed Consolidated Balance Sheets. The offsetting counterparty and cash collateral netting amounts for foreign currency contracts were $3 million andzero respectively, for both assets and liabilities as of June 30, 2026. The offsetting counterparty and cash collateral netting amounts were $2 million andzero, respectively, for both assets and liabilities as of December 31, 2025.

As part of the acquisition (the "Donatelle Acquisition") of Donatelle Plastics, LLC ("Donatelle"), the purchase agreement includes annual contingent earn-out payments based upon customer-specific revenue generated through December 31, 2029, with total accumulated earn-out payments of up to $85 million. The contingent earn-out liability was established using a Monte Carlo simulation and the significant assumption used is the estimated likelihood the customer specific revenue is earned. The contingent earn-out liability estimate represents a recurring fair value measurement with significant unobservable inputs. The fair value of the contingent earn-out liability is sensitive to changes in the interest rates, discount rates and the timing of the future payments, which are based upon estimates of future achievement of the customer specific revenue. During the three and six months ended June 30, 2026, the Company recognized an adjustment of approximately $8 million and $14 million to reflect the latest developments in the future achievement of the customer specific revenue being earned.
