Item 8.01.
Other Events.
On December 1, 2017, Atlanta Gas Light Company ("AGL"), a subsidiary of Southern Company Gas, filed its 2018 annual rate adjustment under the Georgia Rate Adjustment Mechanism with the Georgia Public Service Commission ("Georgia PSC"), which, if approved, would have increased base revenues by $22 million, effective June 1, 2018.   On February 23, 2018, AGL revised its filing to reflect the impacts of federal tax reform legislation enacted in December 2017.  The revised request replaces the $22 million rate increase with a $16 million rate reduction for customers in 2018. The revised request maintains the previously authorized earnings band based on a return on equity between 10.55% and 10.95% and proposes to increase the equity ratio by 3% to 54% to address the negative cash flow and credit metric impacts of the tax reform legislation. AGL also notified the Georgia PSC that it intends to seek a further equity ratio increase of 2% to 56% in its 2019 filing.
The Georgia PSC is expected to rule on the revised request in the second quarter 2018.  The ultimate outcome of this matter cannot be determined at this time.
