18. OPERATING SEGMENTS AND GEOGRAPHIC INFORMATION  The Companys organizational structure consists of global business unit and global regional leadership teams. The Companys eleven operating segments follow its commercial and product-based activities and are based on engagement in business activities, availability of discrete financial information and review of operating results by the Chief Operating Decision Maker at the identified operating segment level.  Nine of the Companys eleven operating segments have been aggregated into three reportable segments based on similar economic characteristics and future prospects, nature of the products and production processes, end-use markets, channels of distribution and regulatory environment. The Companys reportable segments are Global Industrial, Global Institutional and Global Energy. Operating segments that do not meet the quantitative criteria to be separately reported have been combined into Other. The Company provides similar information for Other as compared to its three reportable segments as the Company considers the information regarding its two underlying operating segments as useful in understanding its consolidated results.  The Companys eleven operating segments are aggregated as follows:  Global Industrial  Includes the Water, Food &amp; Beverage, Paper, Life Sciences and Textile Care operating segments. It provides water treatment and process applications, and cleaning and sanitizing solutions primarily to large industrial customers within the manufacturing, food and beverage processing, chemical, mining and primary metals, power generation, pulp and paper, and commercial laundry industries. The underlying operating segments exhibit similar manufacturing processes, distribution methods and economic characteristics.  Global Institutional  Includes the Institutional, Specialty and Healthcare operating segments. It provides specialized cleaning and sanitizing products to the foodservice, hospitality, lodging, healthcare, government and education and retail industries. The underlying operating segments exhibit similar manufacturing processes, distribution methods and economic characteristics.  Global Energy  Includes the Energy operating segment. It serves the process chemicals and water treatment needs of the global petroleum and petrochemical industries in both upstream and downstream applications.  Other  Includes the Pest Elimination operating segment which provides services to detect, eliminate and prevent pests, such as rodents and insects and the CTG operating segment which produces and sells colloidal silica, which is comprised of nano-sized particles of silica in water used primarily for binding and polishing applications.  Corporate  Consistent with the Companys internal management reporting, Corporate amounts in the table above include intangible asset amortization specifically from the Nalco merger and special (gains) and charges, as discussed in Note 3, that are not allocated to the Companys reportable segments.  Comparability of Reportable Segments  The Company evaluates the performance of its non-U.S. dollar functional currency international operations based on fixed currency exchange rates, which eliminate the impact of exchange rate fluctuations on its international operations. Fixed currency amounts are updated annually at the beginning of each year based on translation into U.S. dollars at foreign currency exchange rates established by management, with all periods presented using such rates. The Fixed Currency Rate Change column shown in the following table reflects the impact on previously reported values related to fixed currency exchange rates established by management at the beginning of 2019. The Other column in the table reflects immaterial changes between segments, primarily cost allocations. Further information related to the Companys special (gains) and charges is included in Note 3. The impact of the preceding changes on previously reported full year 2018 and 2017 reportable segment net sales and operating income is summarized as follows:                     December 31, 2018  2018 Reported   Fixed 2018 Revised   Valued at 2018   Currency Valued at 2019 (millions)  Management Rates Other  Rate Change Management Rates Net Sales               Global Industrial   $5,462.4    $-    $(242.2)    $5,220.2  Global Institutional   5,204.5    -    (138.5)    5,066.0  Global Energy   3,501.8    -    (113.0)    3,388.8  Other   877.6    -    (21.9)    855.7  Subtotal at fixed currency rates   15,046.3    -    (515.6)    14,530.7  Effect of foreign currency translation   (378.1)    -    515.6    137.5  Consolidated reported GAAP net sales   $14,668.2    $-    $-    $14,668.2                   Operating Income                 Global Industrial   $768.1    $(1.4)    $(42.3)    $724.4  Global Institutional   1,026.9    -    (19.6)    1,007.3  Global Energy   358.5    (0.4)    (19.6)    338.5  Other   161.3    1.8    (3.1)    160.0  Corporate   (307.1)    -    3.5    (303.6)  Subtotal at fixed currency rates   2,007.7    -    (81.1)    1,926.6  Effect of foreign currency translation   (60.7)    -    81.1    20.4  Consolidated reported GAAP operating income   $1,947.0    $-    $-    $1,947.0                      December 31, 2017  2017 Reported   Fixed 2017 Revised   Valued at 2018   Currency Valued at 2019 (millions)  Management Rates Other  Rate Change Management Rates Net Sales              Global Industrial   $5,106.8    $-    $(211.0)    $4,895.8  Global Institutional   4,910.0    -    (124.2)    4,785.8  Global Energy   3,281.7    -    (75.9)    3,205.8  Other   931.5    -    (20.8)    910.7  Subtotal at fixed currency rates   14,230.0    -    (431.9)    13,798.1  Effect of foreign currency translation   (394.1)    -    431.9    37.8  Consolidated reported GAAP net sales   $13,835.9    $-    $-    $13,835.9                   Operating Income                 Global Industrial   $758.5    $(0.8)    $(35.7)    $722.0  Global Institutional   979.8    (0.5)    (16.6)    962.7  Global Energy   336.1    0.2    (13.4)    322.9  Other   142.5    1.1    (2.9)    140.7  Corporate   (213.9)    -    3.6    (210.3)  Subtotal at fixed currency rates   2,003.0    -    (65.0)    1,938.0  Effect of foreign currency translation   (52.9)    -    65.0    12.1  Consolidated reported GAAP operating income   $1,950.1    $-    $-    $1,950.1   Reportable Segment Information  Financial information for each of the Companys reportable segments is as follows:                             Net Sales   Operating Income (Loss)   (millions)  2019  2018  2017   2019  2018   2017   Global Industrial   $5,569.9    $5,220.2   $4,895.8    $854.7    $724.4    $722.0   Global Institutional   5,235.5    5,066.0   4,785.8    1,042.2    1,007.3    962.7   Global Energy   3,334.0    3,388.8   3,205.8    379.1    338.5    322.9   Other   907.5    855.7   910.7    167.3    160.0    140.7   Corporate   -    -   -    (409.1)    (303.6)    (210.3)   Subtotal at fixed currency   15,046.9    14,530.7   13,798.1    2,034.2    1,926.6    1,938.0   Effect of foreign currency translation   (140.6)    137.5   37.8    (20.4)    20.4    12.1   Consolidated   $14,906.3    $14,668.2   $13,835.9    $2,013.8    $1,947.0    $1,950.1                             The profitability of the Companys operating segments is evaluated by management based on operating income.  The Company has an integrated supply chain function that serves all of its reportable segments. As such, asset and capital expenditure information by reportable segment has not been provided and is not available, since the Company does not produce or utilize such information internally. In addition, although depreciation and amortization expense is a component of each reportable segments operating results, it is not discretely identifiable.
