See our 2015 Annual Report on Form 10-K, Item 8, Note 13, Employee Retirement Benefits, Page 146, for information on our retirement benefits. We made matching contributions totaling $4 million and $3 million to our
401(k) and Top Hat savings plans during the second quarter of 2016 and 2015 and contributions of $8 million and $7 million for the first half of 2016 and 2015, respectively.

We contributed $5 million to our qualified pension plan during the first six months of 2016. We also contributed
$8 million to our qualified pension plan during the third quarter of 2016 and do not anticipate further contributions during the remainder of 2016.
