(1)	Infrastructure mechanisms in Texas, Louisiana and Tennessee allow for the deferral of all eligible expenses associated with capital expenditures incurred pursuant to these rules, including the recording of interest on deferred expenses until the next rate proceeding (rate case or annual rate filing), at which time investment and costs would be recoverable through base rates.

Due to the passage of the Kansas House Bill 2585, on June 1, 2020, we remeasured our deferred tax liability and updated our state deferred tax rate resulting in a $12.1 million regulatory liability as of June 30, 2020. See further details in Note 11. The remaining amount reflects the remeasurement of the net deferred tax liability included in our rate base as a result of the Tax Cuts and Jobs Act of 2017 (the "TCJA"). Of this amount, $20.9 million as of June 30, 2020 and $21.2 million as of September 30, 2019 is recorded in other current liabilities. These liabilities are being returned to customers in most of our jurisdictions on a provisional basis over 15 to 46 years until formal orders establish the final refund periods.
