During the
nine
-month period ended

we contributed
$2.5
million to our defined benefit pension plans. During the remainder of
2018,
we do
not
expect to make additional contributions to these plans.
 
During the
three

nine
-month periods ended
September 30, 2018,
we contributed
$1.5
million and
$5.0
million, respectively, in matching contributions to our
401
(k) Plan. During the remainder of
2018,
we estimate that our contributions will be approximately
