Business Segments BUSINESS SEGMENTS
DPL manages its business through one reportable operating segment, the Utility segment, led by our Chief Executive Officer and Chief Financial Officer who, collectively, are the Chief Operating Decision Maker. The primary segment performance measures are income / (loss) before income tax and net income / (loss) as management has concluded that these measures best reflect the underlying business performance of DPL and are the most relevant measures considered in DPL’s internal evaluation of the financial performance of its segment. The Chief Operating Decision Maker uses income / (loss) before income tax and net income / (loss) in the annual budget and forecasting process, including making decisions on reinvesting profits to support Utility segment growth. On a monthly basis, the Chief Operating Decision Maker reviews variances in budget versus actual results and monitors changes in forecasted results to assess the underlying operating performance and analyze risks and opportunities for the Utility segment.

The Utility segment is comprised of AES Ohio, a public electric transmission and distribution utility, with all other nonutility business activities aggregated separately. See Note 1. Overview and Summary of Significant Accounting Policies for further information on AES Ohio. The “Other” nonutility category primarily includes interest expense, cash and other immaterial balances. The accounting policies of the identified segment are consistent with those policies and procedures described in the summary of significant accounting policies.

The following tables present financial information for DPL’s reportable business segment:

Business Segments BUSINESS SEGMENTS
All of AES Ohio’s current business consists of the transmission, distribution and sale of electric energy, and therefore AES Ohio had only one reportable segment, led by our Chief Executive Officer and Chief Financial Officer, who, collectively, are the Chief Operating Decision Maker. The primary segment performance measures are income / (loss) before income tax and net income / (loss) as management has concluded that these measures best reflect the underlying business performance of AES Ohio and are the most relevant measures considered in AES Ohio's internal evaluation of the financial performance of its segment. The Chief Operating Decision Maker uses income / (loss) before income tax and net income / (loss) to allocate resources and capital in the annual budget and forecasting process, including making decisions on where to reinvest profits to support AES Ohio’s growth. On a monthly basis, the Chief Operating Decision Maker reviews variances in budget versus actual results and monitors changes in forecasted results to assess the underlying operating performance and analyze risks and opportunities for AES Ohio. See Note 1, "Overview and Summary of Significant Accounting Policies" for further information on AES Ohio.
