15.       SEGMENT INFORMATION (NU)

Presentation: NU is organized between the Regulated companies' segments and Other operations based on a combination of factors, including the characteristics of each business' products and services, the sources of operating revenues and expenses and the regulatory environment in which each segment operates.

The Regulated companies' segments include the electric distribution segment, the natural gas distribution segment and the electric transmission segment. The electric distribution segment includes the generation activities of PSNH and WMECO. The Regulated companies' segments represented substantially all of NU's total consolidated revenues for the three and ninemonth periods ended September 30, 2012 and 2011. Regulated companies' revenues from the sale of electricity and natural gas primarily are derived from residential, commercial and industrial customers and are not dependent on any single customer.

Other operations in the tables below primarily consists of 1) the equity in earnings of NU parentfrom its subsidiaries and intercompany interest income, both of which are eliminated in consolidation, and interest income and expense related to the cash and debt of NU parent and NSTAR LLC, respectively, 2) the revenues and expenses of NU's service companies, most of which are eliminated in consolidation, 3) the operations of CYAPC and YAEC,and 4) the results of other subsidiaries, which are comprised of NU Enterprises, NSTAR Communications, Inc., RRR (a real estate subsidiary), the non-energy-related subsidiaries of Yankee and the remaining operations of HWP.

Cash flows used for investments in plant included in the segment information below are cash capital expenditures that do not include amounts incurred but not paid, cost of removal, AFUDC related to equity funds, and the capitalized portions of pension and PBOP expense or income.

As discussed in Note 1A, "Summary of Significant Accounting Policies – Basis of Presentation," certain reclassifications of prior period data were made in the accompanying unaudited condensed consolidated statements of income for NU. Accordingly, the corresponding items of segment information have been recast for all prior periods for comparative purposes.

Effective in the third quarter of 2012, NU's reportable segments are the combined Electric Distribution, Electric Transmission and Natural Gas Distribution segments, based upon the level at which NU's chief operating decision maker assesses performance and makes decisions about the allocation of company resources. Each of NU's subsidiaries, including CL&P, NSTAR Electric, PSNH and WMECO, has one reportable segment. Therefore, separate Transmission and Distribution information is no longer disclosed for CL&P, PSNH or WMECO. NU's operating segments and reporting units are consistent with its reportable business segments.

NU's segment information for the three and nine months ended September 30, 2012 and 2011 is as follows:
