Business Segments

The Company operates in two business segments: High Performance Materials & Components (HPMC) and Flat Rolled Products (FRP). The measure of segment operating profit, which is used to analyze the performance and results of the business segments, excludes all effects of LIFO inventory accounting and any related changes in net realizable value inventory reserves which offset the Company’s aggregate net debit LIFO valuation balance, income taxes, corporate expenses, net interest expense, closed operations expenses and restructuring costs, if any. Management believes segment operating profit, as defined, provides an appropriate measure of controllable operating results at the business segment level. Following is certain financial information with respect to the Company’s business segments for the periods indicated (in millions):

Restructuring and other charges for the third quarter ended September 30, 2016 primarily relate to the indefinite idling of the

Company’s Rowley, UT titanium sponge facility and include $471.3 million of long-lived asset impairment charges, $11.3 million of inventory valuation charges for titanium sponge that are classified in cost of sales, and $17.3 million of facility shutdown, idling and employee benefit costs. The nine months ended September 30, 2016 also include a $9.0 million charge for severance obligations in the FRP operations, and a $1.0 million charge for severance obligations in the HPMC segment. Results for the HPMC segment exclude the Rowley, UT titanium sponge operations beginning with the third quarter of 2016, with such operations being reported in closed operations and other expenses. Reserves for restructuring charges at September 30, 2017 were $9.1 million, of which $3.1 million relates to severance and employee benefit costs and $6.0 million to closure costs. The decline in these reserves compared to $33.1 million at December 31, 2016 is primarily due to payments. These restructuring reserves are expected to be substantially paid in 2017.
