During the nine months ended September 30, 2019, we made contributions and payments of $3.4 million related to our pension plans and $1.2 million related to our OPEB plans. We expect to make contributions and payments of $0.4 million related to our pension plans and $2.4 million related to our OPEB plans during the remainder of 2019, dependent upon various factors affecting us, including our liquidity position and the effects of the Tax Legislation.
