In May 2016, we contributed $51 million to certain qualified defined-benefit pension plans, which was not included in our previous 2016 expected contributions. At June 30, 2016, we now expect to contribute a total of approximately $96 million to our qualified defined-benefit pension plans in 2016.

We froze all future benefit accruals under substantially all of our domestic qualified and foreign and domestic non-qualified defined benefit pension plans several years ago.
