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: Year Ended December 31, (In millions) 2018 2017 2016 Net Sales Specialty Construction Chemicals $ 643.5 $ 615.7 $ 623.8 Specialty Building Materials 481.9 468.7 422.7 Total net sales $ 1,125.4 $ 1,084.4 $ 1,046.5 Segment Operating Income Specialty Construction Chemicals segment operating income $ 40.2 $ 63.4 $ 72.6 Specialty Building Materials segment operating income 113.6 109.4 114.0 Total segment operating income $ 153.8 $ 172.8 $ 186.6 Depreciation and Amortization Specialty Construction Chemicals $ 24.2 $ 21.3 $ 20.0 Specialty Building Materials 14.7 13.2 9.6 Corporate 3.1 2.3 0.2 Total depreciation and amortization $ 42.0 $ 36.8 $ 29.8 Capital Expenditures Specialty Construction Chemicals $ 28.8 $ 23.9 $ 23.6 Specialty Building Materials 12.8 8.5 5.7 Corporate 13.4 12.6 11.6 Total capital expenditures $ 55.0 $ 45.0 $ 40.9 Total Assets Specialty Construction Chemicals $ 408.6 $ 419.9 $ 335.9 Specialty Building Materials 427.8 409.3 273.3 Corporate 441.4 851.3 317.2 Assets held for sale 4.1 22.5 163.4 Total assets $ 1,281.9 $ 1,703.0 $ 1,089.8 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 (related primarily to Argentina for the year ended December 31, 2018 and Venezuela for periods up through its deconsolidation date of July 3, 2017, as discussed in Note 1, "Basis of Presentation and Summary of Significant Accounting and Financial Reporting Policies"), as well as other corporate 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.

For the years ended December 31, 2017 and 2016, corporate costs include approximately $5.4 million and $10.3 million , respectively, that were not allocated to the Darex operating segment as such costs did not meet the criteria to be reclassified to discontinued operations.
