Operating Segment and Geographic Information GCP is engaged in the production and sale of specialty construction chemicals and specialty building materials through two operating segments. Specialty Construction Chemicals ("SCC") operating segment manufactures and markets concrete admixtures and cement additives, and supplies in-transit monitoring systems for concrete producers. Specialty Building Materials ("SBM") operating segment manufactures and markets sheet and liquid membrane systems that protect structures from water, air and vapor penetration, as well as fireproofing and other products designed to protect the building envelope. Operating Segment Data The following table presents information related to GCP's operating segments: Three Months Ended September 30, Nine Months Ended September 30, (In millions) 2019 2018 2019 2018 Net Sales Specialty Construction Chemicals $ 151.8 $ 165.4 $ 433.9 $ 487.4 Specialty Building Materials 115.1 130.9 321.3 361.9 Total net sales $ 266.9 $ 296.3 $ 755.2 $ 849.3 Segment Operating Income Specialty Construction Chemicals segment operating income $ 19.8 $ 12.7 $ 41.9 $ 31.2 Specialty Building Materials segment operating income 25.9 34.3 64.1 84.2 Total segment operating income $ 45.7 $ 47.0 $ 106.0 $ 115.4 Reconciliation of Operating Segment Data to Financial Statements Corporate expenses directly related to the operating segments are allocated to the segment's operating income. GCP excludes from the segments' operating income certain functional costs, certain impacts of foreign currency exchange, as well as certain corporate costs and other costs included in the table below. GCP also excludes from the segment's operating income certain ongoing defined benefit pension costs recognized during each reporting period, which include service and interest costs, the effect of expected returns on plan assets and amortization of prior service costs/credits. GCP believes that the exclusion of certain corporate costs and pension costs provides a better indicator of its operating segment performance since such costs are not managed at an operating segment level.
