Segment Reporting [Abstract] |
Segment Reporting | 14. Segment Reporting Our determination of reportable business segments considers the strategic operating units under which we make financial decisions, allocate resources and assess performance of our business. Our reportable business segments are retail electricity and retail natural gas. The retail electricity segment consists of electricity sales and transmission to residential and commercial customers, and related services. The retail natural gas segment consists of natural gas sales to, and natural gas transportation and distribution for, residential and commercial customers. Corporate and other consists of expenses and assets of the retail electricity and natural gas segments that are managed at a consolidated level such as general and administrative expenses. Asset optimization activities are also included in Corporate and other. For the three months ended March 31, 2022 and 2021, we recorded asset optimization revenues of $27.3 million and $25.7 million and asset optimization cost of revenues of $28.2 million and $25.8 million, respectively, which are presented on a net basis in asset optimization revenues. We use retail gross margin to assess the performance of our operating segments. We have historically defined retail gross margin as operating (loss) income plus (i) depreciation and amortization expenses and (ii) general and administrative expenses, less (i) net asset optimization (expenses) revenues, (ii) net (losses) gains on non-trading derivative instruments, and (iii) net current period cash settlements on non-trading derivative instruments. Based on the events described below related to the February 2021 North American winter storm referred to as Winter Storm Uri ("Winter Storm Uri"), and to ensure Retail Gross Margin reflects repeatable operating performance that is not distorted by non-recurring events or extreme market volatility, we have revised the definition of Retail Gross Margin in this Report to include gains (losses) from non-recurring events (including non-recurring market volatility). We deduct net (losses) gains on non-trading derivative instruments, excluding current period cash settlements, from the retail gross margin calculation in order to remove the non-cash impact of net gains and losses on these derivative instruments. Retail gross margin should not be considered an alternative to, or more meaningful than, operating income, as determined in accordance with GAAP. Below is a reconciliation of retail gross margin to income before income tax expense (in thousands):
