The total net periodic benefit cost for other post-retirement employee benefit plans was less than $1 million, including net credits recognized into "Other comprehensive income (loss)" of less than $1 million, for each of the three and six months ended June 30, 2025 and 2024, respectively.
We contributed $9 million and $7 million to our defined benefit plans for the six months ended June 30, 2025 and 2024, respectively. Additional contributions ranging between approximately $11 million and $15 million are expected to be made during the remainder of 2025.
