4.	RESTRUCTURING AND DIVESTITURE COSTS

During the three and nine months ended September 30, 2015, the Company initiated restructuring and divestiture activities that included: (i) the sale of our aromatics business; (ii) the reorganization of our building products segment comprising workforce and other expense reductions to drive cost savings; and (iii) changes to our corporate management structure.

Discontinued Operations - Aromatics

As discussed in Note 3, the Company expects to incur additional costs with respect to the decommissioning and dismantling of our Plaquemine Phenol Facility. Such costs, some of which may be capitalized, may exceed $20 million for which INEOS may be obligated to reimburse the Company up to $10.0 million. The Company received $5.0 million of that amount as an advance upon the closing of the sale of the aromatics business. The Company’s receipt of all or any portion of the remaining $5.0 million that INEOS may be required to pay and its right to retain the $5.0 million advance will depend on the amount of costs incurred by us in the decommissioning of the Plaquemine Phenol Facility.

Chlorovinyls

During the three and nine month periods ended September 30, 2015, our chlorovinyls segment incurred divestiture costs of $0.2 million and $0.4million, respectively, related to the exit and disposal activities of two immaterial product lines. There were no divestiture related costs during the three and nine month periods ended September 30, 2014.

Building Products

During the three and nine month periods ended September 30, 2015, we incurred: (i) $2.2 million in warranty costs that the Company honored for a previously disposed product line in our building products segment; and (ii) $1.2 million and $1.3 million for severance costs related to management restructuring and workforce reduction charges in our building products segment. Certain payments under these arrangements are expected to conclude by April 1, 2016.

In September of 2013 we initiated a formal plan of restructuring in our building products segment consisting of various cost savings initiatives, including the reduction of overhead and plant labor, and the consolidation of various plants, primarily in the window and door profiles reporting unit, to improve utilization and efficiencies (the “2013 Building Products Restructuring Plan”): (i) during the three and nine month periods ended September 30, 2014 we incurred $1.0 million and $3.9 million, respectively, for severance related and other expense reduction costs to consolidate certain manufacturing operations; (ii) during the nine months ended September 30, 2015, we recognized an impairment charge of $0.3 million to write-down certain long-lived assets to their fair value in our windows and doors reporting unit related to the sale of land and buildings; and (iii) during the three and nine months ended September 30, 2014, we recognized an impairment charge to write-down certain long-lived assets to their estimated fair values of $0.3 million and $1.0 million, respectively, associated with the consolidation of certain building product manufacturing facilities.

Corporate

Restructuring costs included severance costs of $3.6million for both the three and nine month periods ended September 30, 2015 relating to the separation of certain executives under the terms of the Company's severance plans and policies, of which we paid $0.5 million during the nine months ended September 30, 2015. The payments under these separation arrangements are expected to conclude by April 1, 2016. In addition, during the three and nine months ended September 30, 2015 the company incurred $2.8 million and $3.6 million, respectively, in costs associated with divestiture activity, primarily for the sale of our aromatics business and with the strategic review of our building products segment as announced in the second quarter of 2015.
