The impairment relating to the Company’s Mexico reporting unit was recognized as a result of the reporting unit’s fair value declining below its carrying value. The Company estimates the fair value of each of its reporting units based on an average of market and income-based computations, which is a Level 3 measurement.

At December 31, 2025, the Company conducted additional sensitivity analysis on certain assumptions used in the valuation of its European polymers reporting unit due to a decline in earnings.

The Company used both market and income-based methodologies to assess the fair value of its European polymers reporting unit. Both approaches required the Company to make significant economic-related assumptions.
