(a)
Effective January 1, 2016, Southern Company Gas uses a spot rate approach to estimate the service cost and interest cost components. Historically, Southern Company Gas estimated these components using a single weighted-average discount rate.
(G) INCOME TAXES
See Note 13 to the consolidated financial statements of Southern Company Gas in Item 8 of the Form 10-K for additional tax information.
Effective Tax Rate
Southern Company Gas' effective tax rate was 59.6% for the successor period July 1, 2016 through September 30, 2016 and 37.6% for the predecessor period January 1, 2016 through June 30, 2016, compared to 37.9% for the predecessor period nine months ended September 30, 2015. The effective tax rates for the periods in 2016 were impacted by the nondeductibility of certain Merger-related expenses, which were re-assessed in the second and third quarters 2016. The effective tax rate for the successor period July 1, 2016 through September 30, 2016 was also impacted by nondeductible expenses associated with change in control compensation charges. Removing the impact of the Merger-related expenses, the effective tax rate for the predecessor period was 37.5% and for the successor period was 39.1%.
