Regulated Operations [Abstract] |
REGULATION | 3. REGULATION NJNG is subject to cost-based regulation, therefore, it is permitted to recover authorized operating expenses and earn a reasonable return on its utility capital investments based on the BPU's approval. The impact of the ratemaking process and decisions authorized by the BPU allows NJNG to capitalize or defer certain costs that are expected to be recovered from its customers as regulatory assets and to recognize certain obligations representing amounts that are probable future expenditures as regulatory liabilities in accordance with accounting guidance applicable to regulated operations. NJNG's recovery of costs is facilitated through its base rates, BGSS and other regulatory tariff riders. NJNG is required to make annual filings to the BPU for review of its BGSS, CIP and various other programs and related rates. Annual rate changes are typically requested to be effective at the beginning of the following fiscal year. All rate and program changes are subject to proper notification and BPU review and approval. In addition, NJNG is also permitted to implement certain BGSS rate changes on an interim basis with proper notification to the BPU. Regulatory assets and liabilities included on the Unaudited Condensed Consolidated Balance Sheets are comprised of the following:

For a more detailed discussion of the Tax Act, see Note 11. Income Taxes.
(2) | Includes the long-term portion of an adjustment related to the Tax Act.
Regulatory filings and/or actions that occurred during the current fiscal year include the following:
• | On October 20, 2017, the BPU approved NJNG's filing to decrease its EE recovery rate, which will result in an annual decrease of $3.9 million, effective November 1, 2017.
• | On November 17, 2017, NJNG filed its annual SBC application requesting to recover remediation expenses incurred through June 30, 2017, a reduction in the RAC, which will result in an annual decrease of $2.4 million and to increase the NJCEP factor, which will result in an annual increase of $1.8 million, effective April 1, 2018.
• | On December 22, 2017, the Tax Act was signed into law, which resulted in a reduction in the federal corporate tax rate. As a result, NJNG recorded a regulatory liability of $228.4 million, which includes $164.3 million for the revaluation of its deferred income taxes and $64.1 million for the accounting of the income tax effects on the revaluation. The revaluation is based on certain assumptions and estimations NJNG made with respect to its deferred taxes, as well as the effects from the Tax Act, and as such are subject to change if and when assumptions are updated. See Note 11. Income Taxes for a more detailed discussion on the Tax Act.
On January 31, 2018, the BPU issued an Order which directed New Jersey utilities to submit filings to the BPU by March 2, 2018, to propose the prospective change in rates as a result of the Tax Act to be effective April 1, 2018, the method to return to customers the rate difference from January 1, 2018, through March 31, 2018, and an outline of the method by which the excess deferred taxes would be returned to customers. The excess deferred taxes are primarily related to timing differences associated with utility plant depreciation and are subject to IRS normalization rules, which require amortization over the remaining life of the utility plant. On March 1, 2018, NJNG submitted its required filing to the BPU proposing a $19.7 million base rate reduction and customer refunds of approximately $31 million, which is inclusive of the State of New Jersey sales tax. The one-time refunds have been proposed to include interest at the Company’s short-term debt rate as specified in the Company’s last base rate case and these refunds are anticipated to be applied to customer accounts by late May 2018. On March 26, 2018, the BPU approved, on an interim basis, the $19.7 million rate reduction, effective April 1, 2018. A BPU decision on the refunds is anticipated during the third quarter of fiscal 2018.
• | On March 26, 2018, the BPU approved NJNG's petition on a final basis to maintain NJNG's BGSS rate for residential and small commercial customers, increase to its balancing charge rate, which resulted in a $3.7 million increase to the annual revenues credited to BGSS and a decrease to its CIP rates, which resulted in a $16.2 million annual recovery decrease that was effective October 1, 2017.
• | On March 28, 2018, NJNG filed a petition with the BPU requesting continuation of existing SAVEGREEN programs and the addition of new programs through December 2024, with investments of approximately $341 million.
• | On March 29, 2018, NJNG filed its annual petition with the BPU requesting a base rate increase in the amount of $6.9 million for the recovery of NJ RISE and SAFE II capital investment costs related to the 12-months ending June 30, 2018, based on estimates. The filing will be updated to reflect actual results in July 2018, with changes to base rates anticipated to be effective October 1, 2018.
