Segment Reporting Segment Reporting
H2O America’s single reportable segment provides water utility and utility-related services to its customers through H2O America’s subsidiaries, SJWC, CWC, TWC, MWC, and Acequia, which are aggregated and referred to as “Water Utility Services.” Water Utility Services’ activities are water utility operations with both regulated and non-tariffed businesses. Other business activities that do not comprise separately reportable segments primarily include SJWC’s City of Cupertino service concession arrangement operations, property management and investment activity conducted by H2O America Land Company and Chester Realty, Inc., contract water and sewer operations and other water-related services provided by NEWUS are referred to as “Other Services.”
H2O America’s operating segments have been determined based on information used by the chief operating decision maker. H2O America’s chief operating decision makers (“CODM”) include the Chair and Chief Executive Officer; the Chief Financial Officer and Treasurer; the President and Chief Operating Officer; the President of Shared Services and Senior Vice President and Chief Administrative Officer; and the Vice President and General Counsel. However, ultimate decision-making authority rests with the Chair and Chief Executive Officer. The CODM reviews financial information presented on a consolidated basis that is accompanied by certain disaggregated information about operating revenue, expenses, net income, and total assets. The CODM uses the net income to assess the financial performance of the segments and allocate resources (including employees, financial, or capital resources) in the budgeting and forecasting process.
Previously, H2O America presented a separate reportable segment for Real Estate Services and also presented a disaggregation of regulated and non-tariffed activities within the Water Utility Services reportable segment. Considering the sale of the Tennessee properties, as discussed in Note 2, which were part of the Real Estate Services segment, management has updated its segment presentation and has recast the prior periods presented to conform with the current period presentation. Under the current presentation, the activities of Water Utility Services previously presented as “non-tariffed” are generally presented as “Other Services” along with the real estate activity. Certain allocated assets, such as goodwill, revenue and expenses have been included in the reportable segment amounts. Certain corporate costs and expenses are not allocated to Water Utility Services or Other Services and are shown separately to reconcile to the applicable consolidated amounts.
