We made lump-sum settlement payments of $4 million and $5 million for the nine months ended June 30, 2018 and July 1, 2017, respectively, to certain deferred vested participants within our respective non-qualified and qualified pension plans.

We contributed $9 million to our pension plans for the three months ended June 30, 2018 and July 1, 2017. We contributed $27 million and $31 million to our pension plans for the nine months ended June 30, 2018, and July 1, 2017, respectively. We expect to contribute an additional $2 million during the remainder of fiscal 2018. The amount of contributions made to pension plans in any year is dependent upon a number of factors, including minimum funding requirements in the jurisdictions in which we operate. As a result, the actual funding in fiscal 2018 may differ from the current estimate.
