Supplemental Quarterly Financial Data for the Year Ended December 31, 2019 (unaudited)

As part of perfecting the integrated model, in which the majority of the Company’s generation serves its retail customers, the Company began managing its operations based on the combined results of the retail and wholesale generation businesses with a geographical focus in 2020. As a result, the Company changed its business segments to Texas, East and West/Other beginning in the first quarter of 2020. The Company's updated segment structure reflects how management currently makes financial decisions and allocates resources. The unaudited financial information for the previously reported quarterly periods in the year ended December 31, 2019 has been retrospectively revised to reflect the current segment structure, as follows:
