1 Relates to changes in the allocation of deferred tax re-measurement between customers and shareholders as a result of a CPUC resolution issued in February 2019. The resolution determined that customers are only entitled to excess deferred taxes which were included when setting rates, while other deferred tax re-measurement belongs to the shareholders.
2 | In the third quarter of 2019, SCE recorded incremental tax benefits, primarily related to FERC settlement and prior year tax return true up.
