[1] The 2016 tax expense is primarily related to The Dow Chemical settlement. The 2014 tax benefit is primarily related to the Store Fixtures goodwill impairment and the Prime Foam litigation.

[2] We recorded a goodwill impairment charge related to the Commercial Vehicle Products unit as outlined in Note C.

[3] We recorded a goodwill impairment charge related to the Steel Tubing unit as outlined in Note C.

[4] In 2016, we reached a litigation settlement of our antitrust claims against The Dow Chemical Company by agreeing to release our claims regarding this matter for a net cash payment of approximately $38.0 (pretax, after deducting expenses). Of this amount, $31.4 was associated with our former Prime Foam Products unit (previously part of the Residential Products Segment), which we sold in March 2007. The after-tax income associated with the settlement was approximately $25, of which approximately $20 is reflected in discontinued operations. This matter is now fully resolved. In an unrelated matter, accruals of $2.0, $.7 and $35.3 in 2016, 2015 and 2014, respectively were recorded in discontinued operations for antitrust litigation expense associated with the Prime Foam Products unit as discussed in Note S.

[5] This includes goodwill impairment charges of $108.0 in 2014 as discussed in Note C.
