Wildfire Mitigation represents incremental costs and investments made by PGE under Oregon Senate Bill (SB) 762, which was passed in the 2021 legislative session with an effective date of July 19, 2021. SB 762 instructs public utilities to develop, implement, and execute a wildfire protection plan, in which reasonable costs can be recovered through the prices to all customers. The outcome of PGE’s 2022 GRC provided an annual amount of $24 million to be collected in base rates for recovery of operating expenses related to wildfire mitigation efforts beginning May 9, 2022. As of June 30, 2023 and December 31, 2022, PGE’s deferred balance related to wildfire mitigation operating expenses was $32 million and $28 million, respectively. On July 1, 2022, PGE filed an application for reauthorization of OPUC Docket UM 2019 to defer incremental wildfire mitigation costs that exceed the amount granted in base rates.

On May 10, 2023, in Order No. 23-173, the OPUC approved an automatic adjustment clause mechanism to recover wildfire mitigation costs (capital and expense). PGE submitted its tariff filing on May 17, 2023, for new rates to take effect September 1, 2023, to recover: i) incremental expense and capital-related costs that has been deferred under OPUC Docket UM 2019 and ii) forecasted costs based on a 2024 test year (in PGE’s next general rate case it will remove collections related to wildfire mitigation costs from base rates and include within the automatic adjustment clause). This is currently undergoing prudence review by the OPUC. The OPUC’s conclusions of overall prudence could result in a portion of PGE’s deferral being disallowed for recovery. Such disallowance would be recognized as a charge to earnings.

COVID-19—The COVID-19 pandemic led Oregon’s Governor to declare a state of emergency on March 8, 2020. Due to the adverse impacts of COVID-19 on economic activity, PGE experienced an increase in bad debt expense, lost revenue, and other incremental costs. In March 2020, PGE filed an application with the OPUC for deferral of lost revenue and certain incremental costs, such as bad debt expense, related to COVID-19. PGE’s deferral application was approved by the OPUC in October 2020 with final stipulations approved in November 2020.

As June 30, 2023 and December 31, 2022, PGE’s deferred balance was $19 million and $22 million, respectively, comprised primarily of bad debt expense in excess of what is currently considered and collected in customer prices. PGE filed a request for amortization of deferred amounts in December 2022, which reflected a $12 million adjustment primarily related to bad debt write-offs being lower than estimated. During a March 14, 2023 public meeting, Staff recommended the OPUC approve PGE's filing of Advice No. 22-45 associated with the recovery of the COVID-19 deferral. On March 21, 2023, Advice No. 22-45 was approved by the OPUC, allowing for amortization of deferred amounts over a two-year period, which began April 1, 2023.

Deferral of Boardman revenue requirement—In October 2020, intervenors filed a deferral application with the OPUC that would require PGE to defer and refund the revenue requirement associated with the Company’s Boardman coal-fired generating plant (Boardman) then included in customer prices as established in the Company’s 2019 GRC. The application stated a deferral was required for customers to adequately capture the reduction in revenue requirement beginning on October 15, 2020, the date Boardman ceased operations. PGE estimated the revenue requirement for Boardman to be $14 million for the year ended December 31, 2020, an additional $66 million for the year ended December 31, 2021, and $23 million for the year ended December 31, 2022. In the 2022 GRC Order, the OPUC found that the deferral was warranted with amortization subject to an earnings test. On July 27, 2022, the Company filed an application, which, subject to OPUC approval, showed that the Company did not exceed the earnings test threshold for 2020 or 2021 and consequently, no refund would be required for those years. Customer prices resulting from the 2022 GRC Order no longer included any revenue requirement related to Boardman after new customer prices took effect on May 9, 2022. On October 24, 2022, PGE and parties submitted a stipulation with the OPUC reflecting an agreement that resolved all matters related to 2021 under this deferral and states that no refund remains necessary for that year. Based on the application of an earnings test, PGE had not previously recorded a refund related to Boardman for 2020, 2021, or 2022.

On May 30, 2023, PGE and parties submitted a second stipulation with the OPUC reflecting an agreement that resolved all matters related to 2020 and 2022 under this deferral. Parties agreed that PGE would refund $6.5 million to customers related to 2020. The refund amount, plus interest, will be amortized into customer prices over a two-year period beginning July 1, 2023. All parties agreed that there are no amounts to amortize for the 2022 deferral period. On June 5, 2023, the OPUC issued Order 23-195, which approved the stipulations.

Establishing the Boardman refund deferral resulted in an increase to regulatory liabilities with an offsetting charge to the condensed consolidated statements of income for the three months ended June 30, 2023.

Accrued Expenses and Other Current Liabilities

Accrued expenses and other current liabilities consist of the following (in millions):


	June 30, 2023		December 31, 2022
Accrued employee compensation and benefits	$	58	$	66
Accrued taxes payable	25		29
Accrued interest payable	33		31
Accrued dividends payable	48		42
Regulatory liabilities—current	25		234
Margin deposits from wholesale counterparties	5		140
Other	82		99
Total accrued expenses and other current liabilities	$	276	$	641

The current portion of Regulatory liabilities and Margin deposits from wholesale counterparties decreased during the six months ended June 30, 2023 due to decreases in wholesale natural gas and electricity prices. For further information, see Note 5, Risk Management.

Credit Facilities

As of June 30, 2023, PGE had a $650 million revolving credit facility scheduled to expire in September 2027. The Company has the ability to expand the revolving credit facility to $750 million, if needed, subject to the requirements of the agreement. Pursuant to the terms of the agreement, the revolving credit facility may be used for general corporate purposes, including as backup for commercial paper borrowings and to permit the issuance of standby letters of credit. PGE may borrow for one, three, or six months at a fixed interest rate established at the time of the borrowing, or at a variable interest rate for any period up to the then remaining term of the applicable credit facility. The revolving credit facility contains a provision that requires annual fees based on the Company’s unsecured credit ratings, and contains customary covenants and default provisions, including a requirement that limits consolidated indebtedness, as defined in the agreement, to 65% of total capitalization. As of June 30, 2023, PGE was in compliance with this covenant with a 54.0% debt-to-total capital ratio and had no outstanding balance on the revolving credit facility. As a result of the policy to backup commercial paper borrowings, the aggregate unused available credit capacity under the credit facility was $510 million. In addition, the credit facility offers the potential for adjustments to interest rate margins and fees based on PGE’s achievement of certain annual sustainability-linked metrics related to its non-emitting generation capacity and the percentage of management comprised of women and employees who identify as black, indigenous, and people of color. The Company believes these potential adjustments will have an immaterial impact on PGE’s results of operations.

The Company has a commercial paper program under which it may issue commercial paper for terms of up to 270 days. The Company has elected to limit its borrowings under the revolving credit facility in order to allow for coverage of any potential need to repay commercial paper that may be outstanding at the time. As of June 30, 2023, PGE had $140 million commercial paper outstanding.

PGE typically classifies borrowings under the revolving credit facility and outstanding commercial paper as Short-term debt on the condensed consolidated balance sheets.

In addition, PGE has three letter of credit facilities that provide a total capacity of $220 million under which the Company can request letters of credit for original terms not to exceed one year. The issuance of such letters of credit is subject to the approval of the issuing institution. Under these facilities, letters of credit for a total of $92 million were outstanding as of June 30, 2023. Letters of credit issued are not reflected on the Company’s condensed consolidated balance sheets.

Pursuant to an order issued by the FERC, the Company is authorized to issue short-term debt in an aggregate amount of up to $900 million through February 6, 2024.

Long-term Debt

On October 21, 2022, PGE obtained a 366-day term loan from lenders in the aggregate principal of $260 million under a 366-Day Bridge Credit Agreement. The term loan bore interest for the relevant interest period at the Term Secured Overnight Financing Rate (SOFR) plus Term SOFR Adjustment Rate of 10 basis points and applicable margin of 87.5 basis points. The interest rate was subject to adjustment pursuant to the terms of the loan. On March 1, 2023, this term loan was repaid in full with proceeds from the Equity Forward Sale Agreement described in Note 7, Shareholders’ Equity.

On November 30, 2022, PGE entered into a Bond Purchase Agreement related to the sale of $200 million in First Mortgage Bonds (FMBs), the first half of which funded in 2022 and the remaining $100 million funded in full on January 13, 2023.
