[1] Wind PTCs (net of estimated transfer discounts) are generally credited to customers (reduction to revenue) and do not materially impact earnings.
[2] Plant regulatory differences primarily relate to the credit of excess deferred taxes to customers. Income tax benefits associated with the credit are offset by corresponding revenue reductions.
