[1] Included in Income (loss) from discontinued operations (net of tax) for the second quarter of 2016 is a nonrecurring, non-cash tax charge of $416.7 million related to the change in the Company’s assertion over book and tax basis differences for certain entities included in the sale of the Chemetall Surface Treatment business. In the fourth quarter of 2016, this non-cash tax charge was reversed as a result of the completion of the sale. In addition, the fourth quarter of 2016 includes an after-tax gain of $135.0 million as a result of the sale of the Chemetall Surface Treatment business.

[2] Operating expenses, net for discontinued operations includes mark-to market actuarial (losses) gains of ($8.5) million and $8.9 million during the years ended December 31, 2016 and 2015, respectively.

[3] Interest and financing expenses included the allocation of interest expense not directly attributable to other operations as well as interest expense related to debt to be assumed by the buyer. The allocation of interest expense to discontinued operations was based on the ratio of net assets held for sale to the sum of total net assets plus consolidated debt. There was no interest expense allocated to discontinued operations for the year ended December 31, 2014, as the Chemetall Surface Treatment business was not owned by the Company during this period.

[4] Income tax expense for the year ended December 31, 2016 included a charge of $253.0 million related to the gain on sale of discontinued operations.
