Dow contributed $1 billion to its U.S. pension plans and said it would freeze its U.S. plans for active employees as of Dec. 31, 2023.
The company said these actions and the subsequent remeasurement of the U.S. plans effectively reduced Dow’s pension liability by $2.3 billion and decreased its full-year 2021 pension expense by about $200 million, inclusive of a curtailment gain.
In December, analysts at J.P. Morgan turned bullish on the company and raised their rating on Dow stock to overweight from neutral.
