Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict. Our actual results may differ materially from those contemplated by the forward-looking statements. We therefore caution you against relying on any of these forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Important factors that could cause actual results to differ materially from those in the forward-looking statements are discussed in NW Holdings' and NW Natural's 2019 Annual Report on Form 10-K, Part I, Item 1A “Risk Factors” and Part II, Item 7 and Item 7A, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures about Market Risk,” and in Part I, Items 2 and 3, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures About Market Risk”, respectively of Part II of this report.

Any forward-looking statement made in this report speaks only as of the date on which it is made. Factors or events that could cause actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. ORGANIZATION AND PRINCIPLES OF CONSOLIDATION

The accompanying consolidated financial statements represent the respective, consolidated financial results of NW Holdings and NW Natural and all respective companies that each registrant directly or indirectly controls, either through majority ownership or otherwise. This is a combined report of NW Holdings and NW Natural, which includes separate consolidated financial statements for each registrant.

NW Natural's regulated natural gas distribution activities are reported in the natural gas distribution (NGD) segment. The NGD segment is NW Natural's core operating business and serves residential, commercial, and industrial customers in Oregon and southwest Washington. The NGD segment is the only reportable segment for NW Holdings and NW Natural. All other activities, water businesses, and other investments are aggregated and reported as other at their respective registrant.

In addition, NW Holdings has reported discontinued operations results related to the pending sale of Gill Ranch Storage, LLC (Gill Ranch). See Note 17 for additional information.

NW Holdings' direct and indirect wholly-owned subsidiaries as of the filing date of this report include:


•	Northwest Natural Gas Company (NW Natural);


•	Northwest Energy Corporation (Energy Corp);


•	NWN Gas Reserves LLC (NWN Gas Reserves);


•	NW Natural Energy, LLC (NWN Energy);


•	NW Natural Gas Storage, LLC (NWN Gas Storage);


▪	Gill Ranch Storage, LLC (Gill Ranch), which is presented as a discontinued operation;


•	NNG Financial Corporation (NNG Financial);


•	KB Pipeline Company (KB);


•	NW Natural Water Company, LLC (NWN Water);


▪	Falls Water Co., Inc. (Falls Water);


▪	Salmon Valley Water Company;


▪	NW Natural Water of Oregon, LLC (NWN Water of Oregon);


•	Sunstone Water, LLC;


•	Sunstone Infrastructure, LLC;


•	Sunriver Water, LLC (Sunriver Water);


•	Sunriver Environmental, LLC (Sunriver Environmental);


▪	NW Natural Water of Washington, LLC (NWN Water of Washington);


•	Cascadia Infrastructure, LLC;


•	Cascadia Water, LLC (Cascadia);


•	Suncadia Water Company, LLC (Suncadia Water);


•	Suncadia Environmental Company, LLC (Suncadia Environmental);


▪	NW Natural Water of Idaho, LLC (NWN Water of Idaho);


•	Gem State Water Company, LLC (Gem State);


•	Gem State Infrastructure, LLC; and


▪	NW Natural Water of Texas, LLC (NWN Water of Texas);


•	Blue Topaz Water, LLC;


•	Blue Topaz Infrastructure, LLC; and


•	T&W Water Service Company.

Investments in corporate joint ventures and partnerships that NW Holdings does not directly or indirectly control, and for which it is not the primary beneficiary, include NNG Financial's investment in Kelso-Beaver Pipeline and NWN Energy's investment in Trail West Holdings, LLC (TWH), which are accounted for under the equity method. NW Holdings and its direct and indirect subsidiaries are collectively referred to herein as NW Holdings, and NW Natural and its direct and indirect subsidiaries are collectively referred to herein as NW Natural. The consolidated financial statements of NW Holdings and NW Natural are presented after elimination of all intercompany balances and transactions.

Information presented in these interim consolidated financial statements is unaudited, but includes all material adjustments management considers necessary for a fair statement of the results for each period reported including normal recurring accruals. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in NW Holdings' and NW Natural's combined 2019 Annual Report on Form 10-K (2019 Form 10-K). A significant part of NW Holdings' and NW Natural's business is of a seasonal nature; therefore, NW Holdings and NW Natural results of operations for interim periods are not necessarily indicative of full year results. Seasonality affects the comparability of the results of other operations across quarters but not across years.

Table of Contents

During the second quarter of 2018, we moved forward with our long-term strategic plans, which include a shift away from the California gas storage business. In June 2018, NWN Gas Storage, a wholly-owned subsidiary of NW Natural at the time and now a wholly-owned subsidiary of NW Holdings, entered into a Purchase and Sale Agreement that provides for the sale of all of the membership interests in its wholly-owned subsidiary, Gill Ranch, subject to various regulatory approvals and closing conditions. We have concluded that the pending sale of Gill Ranch qualifies as assets and liabilities held for sale and discontinued operations. As such, the results of Gill Ranch have been presented as a discontinued operation for NW Holdings for all periods presented on the consolidated statements of comprehensive income and cash flows, and the assets and liabilities associated with Gill Ranch have been classified as discontinued operations assets and liabilities on the NW Holdings consolidated balance sheet. See Note 17 for additional information.

Notes to the consolidated financial statements reflect the activity of continuing operations for both NW Holdings and NW Natural for all periods presented, unless otherwise noted.

2. SIGNIFICANT ACCOUNTING POLICIES

Significant accounting policies are described in Note 2 of the 2019 Form 10-K. There were no material changes to those accounting policies during the three months ended March 31, 2020 other than those set forth in this Note 2. The following are current updates to certain critical accounting policy estimates and new accounting standards.

Industry Regulation

In applying regulatory accounting principles, NW Holdings and NW Natural capitalize or defer certain costs and revenues as regulatory assets and liabilities pursuant to orders of the Oregon Public Utilities Commission (OPUC), Washington Utilities and Transportation Commission (WUTC), Idaho Public Utilities Commission (IPUC) or Public Utility Commission of Texas (PUCT), which provide for the recovery of revenues or expenses from, or refunds to, utility customers in future periods, including a return or a carrying charge in certain cases.

Amounts deferred as regulatory assets and liabilities for NW Holdings and NW Natural were as follows:

⁽¹⁾	Unrealized gains or losses on derivatives are non-cash items and therefore do not earn a rate of return or a carrying charge. These amounts are recoverable through NGD rates as part of the annual Purchased Gas Adjustment (PGA) mechanism when realized at settlement.


⁽²⁾	Refer to footnote (3) of the Deferred Regulatory Asset table in Note 16 for a description of environmental costs.


⁽³⁾	This deferral represents the margin adjustment resulting from differences between actual and expected volumes.


⁽⁴⁾	Refer to Note 9 for information regarding the deferral of pension expenses.


⁽⁵⁾	Balances consist of deferrals and amortizations under approved regulatory mechanisms and typically earn a rate of return or carrying charge.


⁽⁶⁾	This balance represents estimated amounts associated with the Tax Cuts and Jobs Act. See Note 10.


⁽⁷⁾	Estimated costs of removal on certain regulated properties are collected through rates.

We believe all costs incurred and deferred at March 31, 2020 are prudent. All regulatory assets and liabilities are reviewed annually for recoverability, or more often if circumstances warrant. If we should determine that all or a portion of these regulatory assets or liabilities no longer meet the criteria for continued application of regulatory accounting, then NW Holdings and NW Natural would be required to write-off the net unrecoverable balances in the period such determination is made.

We have applied for regulatory deferrals in the states in which we operate to recover the novel coronavirus (COVID-19) related costs such as incremental bad debt expense, forgone revenues related to late fees and reconnection fees, and other costs that may arise related to the COVID-19 pandemic. As of March 31, 2020, we identified $0.7 million in incremental costs and lost revenue, of which approximately $0.4 million is related to increased bad debt expense. However, until the deferral is probable of recovery, any incremental expenses will be recognized in the results of operations.

New Accounting Standards

We consider the applicability and impact of all accounting standards updates (ASUs) issued by the Financial Accounting Standards Board (FASB). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on NW Holdings' or NW Natural's consolidated financial position or results of operations.

Recently Adopted Accounting Pronouncements

CREDIT LOSSES. On June 16, 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments," which applies to financial assets subject to credit losses and measured at amortized cost. The new standard requires financial assets measured at amortized cost to be presented at the net amount expected to be collected and the allowance for credit losses is to be recorded as a valuation account that is deducted from the amortized cost basis. The amendments in this update were effective beginning January 1, 2020 and were applied with modified retrospective methodology. The adoption of this ASU did not materially affect the financial statements and disclosures of NW Holdings or NW Natural.

The majority of NW Holdings' and NW Natural's financial assets are either short-term in nature, such as trade receivables, or relate to leased gas facilities under approved rate schedules.

Allowance for trade receivables. Accounts receivable consist primarily of amounts due for natural gas sales and transportation services to NGD customers and amounts due for gas storage services. The payment term of these receivables is generally 15

Table of Contents

days. NW Holdings and NW Natural establish allowances for uncollectible accounts (allowance) for trade receivables, including accrued unbilled revenue, based on customer types that share similar risk characteristics: residential, commercial, and industrial. For these short-term receivables, it is not expected that forecasted economic conditions would significantly affect the loss estimates under stable economic conditions. For extreme situations like a financial crisis, natural disaster, and the economic slowdown caused by pandemics like COVID-19, we enhance our review and analysis. Please refer to the section on COVID-19 impact below for more discussion.

COVID-19 Impact. COVID-19, which was declared a pandemic by the World Health Organization in March 2020, has resulted in widespread global, national and local effects. On March 23, 2020, the Governors of Oregon and Washington, the states in which NW Natural’s service territories are located, issued stay at home executive orders. These and subsequent executive orders required the closure of “non-essential” businesses and permitted the continuation of “essential services.” As a result of these measures, NW Natural issued a notification in mid-March that it would not charge late payment fees or disconnect customers for late payment. Furthermore, we suspended sending outstanding receivable balances to collections.

After taking into the consideration the significant exposure to quarantine-related job losses in Oregon and Washington state, NW Holdings and NW Natural looked beyond our standard review procedures for our allowance for uncollectible accounts calculation, including analyzing the significant indications of unemployment rate and comparing to historic economic data during the 2007-2009 time period where the country experienced an economic recession. We then considered other qualitative information including data from our call center such as recent trends in credit-related calls. We also reviewed statistics from our website for increases in credit-related inquiries. Finally, we considered the economic stimulus provided by the federal government which could have a beneficial impact on residential and commercial customers' abilities to ultimately make payment on their accounts. Taking all of these factors into consideration, we concluded a reasonable adjustment to the uncollectible provision for customer accounts as of March 31, 2020 would be a 50% increase in net write-offs as a percentage of gas sales for residential and small commercial customers. Our method for estimating our industrial provision for uncollectible accounts remains the same as the level of accounts receivable was lower due to reduced demand in the first quarter of 2020.

The following table presents the activity related to the NW Holdings provision for uncollectible accounts by pool, substantially all of which is related to NW Natural's accounts receivable:



	As of									As of
	January 1, 2020		Three Months Ended March 31, 2020							March 31, 2020
In thousands	Beginning Balance		Provision recorded		Write-offs recognized		Write-offs recovered			Ending Balance
Allowance for uncollectible accounts

Accrued unbilled and other	112		2		—		(3		)	111
Total	$	673	$	694	$	6	$	(38	)	$	1,335

Allowance for net investments in sales-type leases. NW Natural currently holds two net investments in sales-type leases, with substantially all of the net investment balance related to the North Mist natural gas storage agreement with Portland General Electric (PGE) which is billed under an OPUC-approved rate schedule. See Note 6 for more information on the North Mist lease. Due to the nature of this service, PGE may recover the costs of the lease through general rate cases. Therefore, we expect the risk of loss due to the credit of this lessee to be very low. As such, no allowance for uncollectibility was recorded for our sales-type lease receivables. NW Natural will continue monitoring the credit health of the lessees and the overall economic environment, including the economic factors closely tied to the financial health of our current and future lessees.

FAIR VALUE MEASUREMENT. On August 28, 2018, the FASB issued ASU 2018-13, "Changes to the Disclosure Requirements for Fair Value Measurement." The purpose of the amendment is to modify the disclosure requirements for fair value measurements. The amendments in this update were effective for us beginning January 1, 2020. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively. All other amendments should be applied retrospectively. NW Holdings and NW Natural do not have either Level 3 fair value measurements or transfers between Level 1 or Level 2 in their current portfolios. The adoption did not have an impact on the financial statements or disclosures of NW Holdings or NW Natural.

RETIREMENT BENEFITS. On August 28, 2018, the FASB issued ASU 2018-14, "Changes to the Disclosure Requirements for Defined Benefit Plans." The purpose of the amendment is to modify the disclosure requirements for defined benefit pension and other postretirement plans. The amendments in this update were effective for us beginning January 1, 2020 and were applied

Table of Contents

retrospectively. The adoption of this ASU did not materially affect the financial statements and disclosures of NW Holdings or NW Natural.

CLOUD COMPUTING. On August 29, 2018, the FASB issued ASU 2018-15, "Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The purpose of the amendment is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments in this update are effective for us beginning January 1, 2020. Early adoption is permitted, and NW Holdings and NW Natural early adopted ASU 2018-15 in the quarter ended March 31, 2019 utilizing the prospective application methodology. The adoption of this ASU did not materially affect the financial statements and disclosures of NW Holdings or NW Natural.

GOODWILL. On January 26, 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment." The ASU removes Step 2 from the goodwill impairment test and under the amended guidance an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount in which the carrying amounts exceed the fair value of the reporting unit. The amendments in this standard are effective for us beginning January 1, 2020 and early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. NW Natural early adopted ASU 2017-04 in the quarter ended September 30, 2018. The adoption of this ASU did not materially affect the financial statements and disclosures of NW Holdings or NW Natural.

Recently Issued Accounting Pronouncements

INCOME TAXES. On December 18, 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The purpose of the amendment is to reduce cost and complexity related to accounting for income taxes by removing certain exceptions to the general principles and improving consistent application for other areas in Topic 740. The amendments in this update are effective for us beginning January 1, 2021. Early adoption is permitted. The amended presentation and disclosure guidance should be applied retrospectively. We do not expect this ASU to materially affect the financial statements and disclosures of NW Holdings or NW Natural.

REFERENCE RATE REFORM. On March 12, 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The purpose of the amendment is to provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. We do not expect this ASU to materially affect the financial statements and disclosures of NW Holdings or NW Natural.

3. EARNINGS PER SHARE

Basic earnings per share are computed using NW Holdings' net income and the weighted average number of common shares outstanding for each period presented. Diluted earnings per share are computed in the same manner, except using the weighted average number of common shares outstanding plus the effects of the assumed exercise of stock options and the payment of estimated stock awards from other stock-based compensation plans that are outstanding at the end of each period presented. Anti-dilutive stock awards are excluded from the calculation of diluted earnings per common share.

4. SEGMENT INFORMATION

We primarily operate in one reportable business segment, which is NW Natural's local gas distribution business and is referred to as the NGD segment. NW Natural and NW Holdings also have investments and business activities not specifically related to the NGD, which are aggregated and reported as other and described below for each entity.

Natural Gas Distribution

NW Natural's local gas distribution segment is a regulated utility principally engaged in the purchase, sale, and delivery of natural gas and related services to customers in Oregon and southwest Washington. In addition to NW Natural's local gas distribution business, the NGD segment also includes the portion of the Mist underground storage facility used to serve NGD customers, the North Mist gas storage expansion, and NWN Gas Reserves, which is a wholly-owned subsidiary of Energy Corp.

NW Natural

NW Natural's activities in Other include Interstate Storage Services and third-party asset management services for the Mist facility, appliance retail center operations, and corporate operating and non-operating revenues and expenses that cannot be allocated to NGD operations.

Earnings from Interstate Storage Services assets are primarily related to firm storage capacity revenues. Earnings from the Mist facility also include revenue, net of amounts shared with NGD customers, from management of NGD assets at Mist and upstream pipeline capacity when not needed to serve NGD customers. Under the Oregon sharing mechanism, NW Natural retains 80% of the pre-tax income from these services when the costs of the capacity were not included in NGD rates, or 10% of the pre-tax income when the costs have been included in these rates. The remaining 20% and 90%, respectively, are recorded in a deferred regulatory account for prospective NGD customer billing credits.

Natural Gas Distribution Margin

NGD margin is a financial measure used by the Chief Operating Decision Maker (CODM), consisting of NGD operating revenues, reduced by the associated cost of gas, environmental remediation expense, and revenue taxes. The cost of gas purchased for NGD customers is generally a pass-through cost in the amount of revenues billed to regulated NGD customers. Environmental remediation expense represents collections received from customers through the environmental recovery mechanism in Oregon as well as adjustments for the environmental earnings test when applicable. This is offset by environmental remediation expense presented in operating expenses. Revenue taxes are collected from NGD customers and remitted to taxing authorities. The collections from customers are offset by the expense recognition of the obligation to the taxing authority. By subtracting cost of gas, environmental remediation expense, and revenue taxes from NGD operating revenues, NGD margin provides a key metric used by the CODM in assessing the performance of the NGD segment.

NW Natural's revenue represents substantially all of NW Holdings' revenue and is recognized for both registrants when the obligation to customers is satisfied and in the amount expected to be received in exchange for transferring goods or providing services. Revenue from contracts with customers contains one performance obligation that is generally satisfied over time, using the output method based on time elapsed, due to the continuous nature of the service provided. The transaction price is determined by a set price agreed upon in the contract or dependent on regulatory tariffs. Customer accounts are settled on a monthly basis or paid at time of sale and based on historical experience. It is probable that we will collect substantially all of the consideration to which we are entitled. We evaluated the probability of collection in accordance with the current expected credit losses standard.

NW Holdings and NW Natural do not have any material contract assets, as net accounts receivable and accrued unbilled revenue balances are unconditional and only involve the passage of time until such balances are billed and collected. NW Holdings and NW Natural do not have any material contract liabilities.

Revenue taxes are included in operating revenues with an equal and offsetting expense recognized in operating expense in the consolidated statements of comprehensive income. Revenue-based taxes are primarily franchise taxes, which are collected from NGD customers and remitted to taxing authorities.

Natural Gas Distribution

Natural gas sales. NW Natural's primary source of revenue is providing natural gas to customers in the NGD service territory, which includes residential, commercial, industrial and transportation customers. NGD revenue is generally recognized over time upon delivery of the gas commodity or service to the customer, and the amount of consideration received and recognized as revenue is dependent on the Oregon and Washington tariffs. Customer accounts are to be paid in full each month, and there is no right of return or warranty for services provided. Revenues include firm and interruptible sales and transportation services, franchise taxes recovered from the customer, late payment fees, service fees, and accruals for gas delivered but not yet billed (accrued unbilled revenue). The accrued unbilled revenue balance is based on estimates of deliveries during the period from the last meter reading and management judgment is required for a number of factors used in this calculation, including customer use and weather factors.

Table of Contents

We applied the significant financing practical expedient and have not adjusted the consideration NW Natural expects to receive from NGD customers for the effects of a significant financing component as all payment arrangements are settled annually. Due to the election of the right to invoice practical expedient, we do not disclose the value of unsatisfied performance obligations as of March 31, 2020.

Alternative revenue. Weather normalization (WARM) and decoupling mechanisms are considered to be alternative revenue programs. Alternative revenue programs are considered to be contracts between NW Natural and its regulator and are excluded from revenue from contracts with customers.

Leasing revenue. Leasing revenue primarily consists of revenues from NW Natural's North Mist Storage contract with Portland General Electric (PGE) in support of PGE's gas-fired electric power generation facilities under an initial 30-year contract with options to extend, totaling up to an additional 50 years upon mutual agreement of the parties. The facility is accounted for as a sales-type lease with regulatory accounting deferral treatment. The investment is included in rate base under an established cost-of-service tariff schedule, with revenues recognized according to the tariff schedule and as such, profit upon commencement was deferred and will be amortized over the lease term. Leasing revenue also contains rental revenue from small leases of property owned by NW Natural to third parties. The majority of these transactions are accounted for as operating leases and the revenue is recognized over the term of the lease agreement. Lease revenue is excluded from revenue from contracts with customers. See Note 6.

NW Natural Other

Gas storage revenue. NW Natural's other revenue includes gas storage activity, which includes Interstate Storage Services used to store natural gas for customers. Gas storage revenue is generally recognized over time as the gas storage service is provided to the customer and the amount of consideration received and recognized as revenue is dependent on set rates defined per the storage agreements. Noncash consideration in the form of dekatherms of natural gas is received as consideration for providing gas injection services to gas storage customers. This noncash consideration is measured at fair value using the average spot rate. Customer accounts are generally paid in full each month, and there is no right of return or warranty for services provided. Revenues include firm and interruptible storage services, net of the profit sharing amount refunded to NGD customers.

Asset management revenue. Revenues include the optimization of the storage assets and pipeline capacity and are provided net of the profit sharing amount refunded to NGD customers. Certain asset management revenues received are recognized over time using a straight-line approach over the term of each contract, and the amount of consideration received and recognized as revenue is dependent on a variable pricing model. Variable revenues earned above guaranteed amounts are estimated and recognized at the end of each period using the most likely amount approach. Additionally, other asset management revenues may be based on a fixed rate. Generally, asset management accounts are settled on a monthly basis.

As of March 31, 2020, unrecognized revenue for the fixed component of the transaction price related to gas storage and asset management revenue was approximately $69.7 million. Of this amount, approximately $12.3 million will be recognized during the remainder of 2020, $18.2 million in 2021, $14.5 million in 2022, $11.6 million in 2023, $7.8 million in 2024 and $5.3 million thereafter. The amounts presented here are calculated using current contracted rates.

Appliance retail center revenue. NW Natural owns and operates an appliance store that is open to the public, where customers can purchase natural gas home appliances. Revenue from the sale of appliances is recognized at the point in time in which the appliance is transferred to the third party responsible for delivery and installation services and when the customer has legal title to the appliance. It is required that the sale be paid for in full prior to transfer of legal title. The amount of consideration received and recognized as revenue varies with changes in marketing incentives and discounts offered to customers.

NW Holdings Other

NW Holdings' primary source of other revenue is providing water and wastewater services to customers. Water distribution revenue is generally recognized over time upon delivery of the water commodity or service to the customer, and the amount of consideration received and recognized as revenue is dependent on the Oregon, Washington, Idaho and Texas tariffs. Customer accounts are to be paid in full each month, and there is no right of return or warranty for services provided.

We applied the significant financing practical expedient and have not adjusted the consideration we expect to receive from water distribution customers for the effects of a significant financing component as all payment arrangements are settled annually. Due to the election of the right to invoice practical expedient, we do not disclose the value of unsatisfied performance obligations as of March 31, 2020.

6. LEASES

Lease Revenue

Leasing revenue primarily consists of NW Natural's North Mist natural gas storage agreement with Portland General Electric (PGE) which is billed under an OPUC-approved rate schedule and includes an initial 30-year term with options to extend, totaling up to an additional 50 years upon mutual agreement of the parties. Under U.S. GAAP, this agreement is classified as a sales-type lease and qualifies for regulatory accounting deferral treatment. The investment in the storage facility is included in rate base under a separately established cost-of-service tariff, with revenues recognized according to the tariff schedule. As

Table of Contents

such, the selling profit that was calculated upon commencement as part of the sale-type lease recognition was deferred and will be amortized over the lease term. Billing rates under the cost-of-service tariff will be updated annually to reflect current information including depreciable asset levels, forecasted operating expenses, and the results of regulatory proceedings, as applicable, and revenue received under this agreement is recognized as operating revenue on the consolidated statements of comprehensive income. There are no variable payments or residual value guarantees. The lease does not contain an option to purchase the underlying assets.

NW Natural also maintains a sales-type lease for specialized compressor facilities to provide high pressure compressed natural gas (CNG) services. Lease payments are outlined in an OPUC-approved rate schedule over a 10-year term. There are no variable payments or residual value guarantees. The selling profit computed upon lease commencement was not significant.

Our lessor portfolio also contains small leases of property owned by NW Natural to third parties. These transactions are accounted for as operating leases and the revenue is recognized over the term of the lease agreement.

The total amount of unguaranteed residual assets was $4.1 million and $4.0 million at March 31, 2020 and December 31, 2019, respectively, and is included in assets under sales-type leases on the consolidated balance sheets. Additionally, under regulatory accounting, the revenues and expenses associated with these agreements are presented on the consolidated statements of comprehensive income such that their presentation aligns with similar regulated activities at NW Natural.

Lease Expense

Operating Leases

We have operating leases for land, buildings and equipment. Our primary lease is for NW Natural's corporate operations center. Our leases have remaining lease terms of less than one year to 20 years. Many of our lease agreements include options to extend the lease, which we do not include in our minimum lease terms unless they are reasonably certain to be exercised. Short-term leases with a term of 12 months or less are not recorded on the balance sheet. As most of our leases do not provide an implicit rate and are entered into by NW Natural, we use an estimated discount rate representing the rate we would have incurred to finance the funds necessary to purchase the leased asset and is based on information available at the lease commencement date in determining the present value of lease payments.

Commencement of Significant Lease

In October 2017, NW Natural entered into a 20-year operating lease agreement for a new corporate operations center in Portland, Oregon in anticipation of the expiration of the current corporate operations center lease in 2020. The lease

Table of Contents

commenced in March 2020 upon substantial completion of the landlord's work. Total estimated base rent payments over the life of the lease are $159.3 million. There is an option to extend the term of the lease for two additional periods of seven years.

There is a material timing difference between the minimum lease payments and expense recognition as calculated under operating lease accounting rules. OPUC issued an order allowing us to align our expense recognition with cash payments for ratemaking purposes. We recorded the difference between the minimum lease payments and the aggregate of the imputed interest on the finance lease obligation and amortization of the right-of-use asset as a deferred regulatory asset on our balance sheet. The balance of the regulatory asset as of March 31, 2020 was $0.6 million.

Finance Leases

NW Natural also leases building storage spaces for use as a gas meter room in order to provide natural gas to multifamily or mixed use developments. These contracts are accounted for as finance leases and typically involve a one-time upfront payment with no remaining liability. The right of use asset for finance leases was $0.7 million, $0.2 million and $0.5 million at March 31, 2020 and 2019 and at December 31, 2019, respectively.

7. STOCK-BASED COMPENSATION

Stock-based compensation plans are designed to promote stock ownership in NW Holdings by employees and officers. These compensation plans include a Long Term Incentive Plan (LTIP), an Employee Stock Purchase Plan (ESPP), and a Restated Stock Option Plan. For additional information on stock-based compensation plans, see Note 8 in the 2019 Form 10-K and the updates provided below.

Long Term Incentive Plan

Performance Shares

LTIP performance shares incorporate a combination of market, performance, and service-based factors. During the three months ended March 31, 2020, the final performance factor under the 2018 LTIP was approved and 39,784 performance-based shares were granted under the 2018 LTIP for accounting purposes. As such, NW Natural and other subsidiaries began recognizing compensation expense. In February 2020 and 2019, LTIP shares were awarded to participants; however, the agreements allow for one of the performance factors to remain variable until the first quarter of the third year of the award period. As the performance factor will not be approved until the first quarters of 2022 and 2021, respectively, there is not a mutual understanding of the awards' key terms and conditions between NW Holdings and the participants as of March 31, 2020, and therefore, no expense was recognized for the 2020 and 2019 awards. NW Holdings will calculate the grant date fair value and NW Natural will recognize expense over the remaining service period for each award once the final performance factor has been approved.

For the 2020 and 2019 LTIP awards, share payouts range from a threshold of 0% to a maximum of 200% based on achievement of pre-established goals. The performance criteria for the 2020 and 2019 performance shares consists of a three-year Return on Invested Capital (ROIC) threshold that must be satisfied and a cumulative EPS factor, which can be modified by a total shareholder return factor (TSR modifier) relative to the performance of the Russell 2500 Utilities Index over the performance period of three years for each respective award. If the targets were achieved for the 2020 and 2019 awards, NW Holdings would grant for accounting purposes 31,830 and 35,170 shares in the first quarters of 2022 and 2021, respectively.

As of March 31, 2020, there was $0.8 million of unrecognized compensation cost associated with the 2018 LTIP grants, which is expected to be recognized through 2020.

Restricted Stock Units

During the three months ended March 31, 2020, 31,076 RSUs were granted, under the LTIP with a weighted-average grant date fair value of $72.38 per share. Generally, the RSUs awarded are forfeitable and include a performance-based threshold as well as a vesting period of four years from the grant date. The majority of our RSU grants obligate NW Holdings, upon vesting, to issue the RSU holder one share of common stock. The grant may also include a cash payment equal to the total amount of dividends paid per share between the grant date and vesting date of that portion of the RSU depending on the structure of the award agreement. The fair value of an RSU is equal to the closing market price of common stock on the grant date. As of March 31, 2020, there was $4.7 million of unrecognized compensation cost from grants of RSUs, which is expected to be recognized by NW Natural and other subsidiaries over a period extending through 2025.

8. DEBT

Short-Term Debt

At March 31, 2020, NW Holdings and NW Natural had short-term debt outstanding of $550.0 million and $450.0 million, respectively. NW Holdings' short-term debt consisted of $100.0 million in revolving credit agreement loan at NW Holdings, and at NW Natural $227.0 million in revolving credit agreement loans, a $150.0 million 364-day term loan, and $73.0 million of commercial paper. The carrying cost of commercial paper approximates fair value using Level 2 inputs. See Note 2 in the 2019 Form 10-K for a description of the fair value hierarchy. The maximum remaining maturity and average remaining maturity of NW Natural's commercial paper was 45 days and 25 days at March 31, 2020.

On March 23, 2020, NW Natural entered into a $150.0 million 364-day term loan credit agreement. NW Natural borrowed the full amount thereunder. The proceeds of which are expected to be used for general corporate purposes and to provide additional liquidity. All principal and unpaid interest under the Term Loan is due and payable on March 22, 2021. NW Natural may prepay the principal and interest, and amounts prepaid may not be reborrowed. The Term Loan requires that NW Natural maintain credit ratings with Standard & Poor’s and Moody’s Investor Services. A change in NW Natural’s debt ratings may result in a change to the interest rate on the Term Loan but is not an event of default. The Term Loan requires NW Natural to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the banks to terminate their lending commitments and to accelerate the maturity of all amounts outstanding. NW Natural was in compliance with the

Table of Contents

covenant requiring the maintenance of an indebtedness to total capitalization ratio as of March 31, 2020, with a consolidated indebtedness to total capitalization ratio of 61.4%.

Long-Term Debt

At March 31, 2020, NW Holdings and NW Natural had long-term debt outstanding of $954.2 million and $917.1 million, respectively, which included $7.6 million of unamortized debt issuance costs at NW Natural. NW Natural's long-term debt consists of first mortgage bonds (FMBs) with maturity dates ranging from 2021 through 2050, interest rates ranging from 2.822% to 9.050%, and a weighted average interest rate of 4.598%.

In March 2020, NW Natural issued $150.0 million of FMBs with an interest rate of 3.60%, due in 2050. In February 2020, NW Natural retired $75.0 million of FMBs with an interest rate of 5.37%.

In June 2019, NW Natural Water, a wholly-owned subsidiary of NW Holdings, entered into a new two-year term loan agreement for $35.0 million, due in 2021. The loan carried an interest rate of 1.82% at March 31, 2020, which is based upon the three-month LIBOR rate. The loan is guaranteed by NW Holdings and requires NW Holdings to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Holdings was in compliance with this covenant at March 31, 2020, with a consolidated indebtedness to total capitalization ratio of 62.5%.

Fair Value of Long-Term Debt

NW Holdings' and NW Natural's outstanding debt does not trade in active markets. The fair value of long-term debt is estimated using the value of outstanding debt at natural gas distribution companies with similar credit ratings, terms, and remaining maturities to NW Holdings' and NW Natural's debt that actively trade in public markets. Substantially all outstanding debt at NW Holdings is comprised of NW Natural debt. These valuations are based on Level 2 inputs as defined in the fair value hierarchy. See Note 2 in the 2019 Form 10-K for a description of the fair value hierarchy.

The following table provides an estimate of the fair value of NW Holdings' long-term debt, including current maturities of long-term debt, using market prices in effect on the valuation date:

9. PENSION AND OTHER POSTRETIREMENT BENEFIT COSTS

NW Natural maintains a qualified non-contributory defined benefit pension plan (Pension Plan), non-qualified supplemental pension plans for eligible executive officers and other key employees, and other postretirement employee benefit plans. NW Natural also has a qualified defined contribution plan (Retirement K Savings Plan) for all eligible employees. The Pension Plan and Retirement K Savings Plan have plan assets, which are held in qualified trusts to fund retirement benefits.

The service cost component of net periodic benefit cost for NW Natural pension and other postretirement benefit plans is recognized in operations and maintenance expense in the consolidated statements of comprehensive income. The other non-service cost components are recognized in other income (expense), net in the consolidated statements of comprehensive income.

Table of Contents

The following table provides the components of net periodic benefit cost for the pension and other postretirement benefit plans:

Net periodic benefit costs are reduced by amounts capitalized to NGD plant. In addition, a certain amount of net periodic benefit costs were recorded to the regulatory balancing account, representing net periodic pension expense for the qualified plan above the amount set in rates, as approved by the OPUC, from 2011 through October 31, 2018.

In March 2019, the OPUC issued an order concluding the NW Natural 2018 Oregon rate case. The Order allowed for the application of certain deferred revenues and tax benefits from the TCJA to reduce NW Natural's pension regulatory balancing account. A corresponding total of $12.5 million in pension expenses were recognized in operating and maintenance expense and other income (expense), net in the consolidated statements of comprehensive income in the first quarter of 2019, with offsetting benefits recorded within operating revenues and income taxes. The Order also directed NW Natural to reduce the balancing account by an additional $10.5 million, which was also charged to operating and maintenance expense and other income (expense), net in the consolidated statements of comprehensive income. Amortization of the remaining amount of the balancing account began in the second quarter of 2019 in accordance with the Order.

The following table presents amounts recognized in accumulated other comprehensive loss (AOCL) and the changes in AOCL related to non-qualified employee benefit plans:

⁽¹⁾	Reclassification of $1.4 million of income tax effects resulting from the TCJA from accumulated other comprehensive loss to retained earnings was made pursuant to the adoption of ASU 2018-02. See Note 2.

Employer Contributions to Company-Sponsored Defined Benefit Pension Plans

For the three months ended March 31, 2020, NW Natural made cash contributions totaling $3.2 million to qualified defined benefit pension plans. NW Natural expects further plan contributions of $25.0 million during the remainder of 2020.

Defined Contribution Plan

The Retirement K Savings Plan is a qualified defined contribution plan under Internal Revenue Code Sections 401(a) and 401(k). Employer contributions totaled $2.5 million and $2.1 million for the three months ended March 31, 2020 and 2019, respectively.

See Note 10 in the 2019 Form 10-K for more information concerning these retirement and other postretirement benefit plans.

10. INCOME TAX

An estimate of annual income tax expense is made each interim period using estimates for annual pre-tax income, regulatory flow-through adjustments, tax credits, and other items. The estimated annual effective tax rate is applied to year-to-date, pre-tax income to determine income tax expense for the interim period consistent with the annual estimate. Discrete events are recorded in the interim period in which they occur or become known.

The effective income tax rate varied from the federal statutory rate due to the following:



	Three Months Ended March 31,
	NW Holdings						NW Natural
In thousands	2020			2019			2020			2019
Income tax at statutory rate (federal)	$	13,105		$	11,022		$	13,355		$	11,159

Effective income tax rate for continuing operations	22.8		%	16.7		%	22.8		%	16.8		%

The NW Holdings and NW Natural effective income tax rates for the three months ended March 31, 2020 compared to the same periods in 2019 changed primarily as a result of changes in pre-tax income and regulatory amortization of deferred TCJA benefits as approved in the March 2019 OPUC order. See "U.S. Federal TCJA Matters" below and Note 11 in the 2019 Form 10-K for more detail on income taxes and effective tax rates.

The 2018 and 2019 tax years are currently under IRS examination as part of the Compliance Assurance Process (CAP). The 2020 tax year CAP application has been accepted by the IRS.

U.S. Federal TCJA Matters

On December 22, 2017, the TCJA was enacted and permanently lowered the U.S. federal corporate income tax rate to 21% from the previous maximum rate of 35%, effective for the tax year beginning January 1, 2018. The TCJA included specific provisions related to regulated public utilities that provide for the continued deductibility of interest expense and the elimination of bonus tax depreciation for property both acquired and placed into service on or after January 1, 2018. See Note 11 in the 2019 Form 10-K.

NW Holdings

Other plant balances include long-lived assets associated with water operations and non-regulated activities not held by NW Natural or its subsidiaries.

NW Natural

Other plant balances include long-lived assets not related to NGD.

In May 2019, NW Natural placed its North Mist gas storage expansion project into service and commenced storage services to the facility's single customer, Portland General Electric (PGE). Under U.S. GAAP, this agreement is classified as a sales-type lease and qualifies for regulatory accounting deferral treatment. Accordingly, the project was de-recognized from property, plant and equipment upon lease commencement and the investment balance is presented net of the current portion of scheduled billings within assets under sales-type leases on the consolidated balance sheets. A total of $146.0 million was de-recognized from plant on the lease commencement date. See Note 6 for information regarding leases, including North Mist.

12. GAS RESERVES

NW Natural has invested $188 million through the gas reserves program in the Jonah Field located in Wyoming as of March 31, 2020. Gas reserves are stated at cost, net of regulatory amortization, with the associated deferred tax benefits recorded as liabilities in the consolidated balance sheets. The investment in gas reserves provides long-term price protection for NGD customers through the original agreement with Encana Oil & Gas (USA) Inc. under which NW Natural invested $178 million and the amended agreement with Jonah Energy LLC under which an additional $10 million was invested.

The cost of gas, including a carrying cost for the rate base investment, is included in the annual Oregon PGA filing, which allows NW Natural to recover these costs through customer rates. The investment under the original agreement, less accumulated amortization and deferred taxes, earns a rate of return. See Note 13 in the 2019 Form 10-K.

Gas produced from the additional wells is included in the Oregon PGA at a fixed rate of $0.4725 per therm, which approximates the 10-year hedge rate plus financing costs at the inception of the investment.

NW Natural's investment is included in NW Holdings' and NW Natural's consolidated balance sheets under gas reserves with the maximum loss exposure limited to the investment balance.

13. INVESTMENTS

Investments in Gas Pipeline

Trail West Pipeline, LLC (TWP), a wholly-owned subsidiary of TWH, is pursuing the development of a new gas transmission pipeline that would provide an interconnection with NW Natural's NGD system. NWN Energy, a wholly-owned subsidiary of NW Holdings, owns 50% of TWH, and 50% is owned by TransCanada American Investments Ltd., an indirect wholly-owned subsidiary of TC Energy Corporation.

Variable Interest Entity (VIE) Analysis

TWH is a VIE, with NW Holdings' investment in TWP reported under equity method accounting. It has been determined that NW Holdings is not the primary beneficiary of TWH’s activities as it only has a 50% share of the entity, and there are no stipulations that allow NW Holdings a disproportionate influence over it. Investments in TWH and TWP are included in other investments in NW Holdings' balance sheet. If this investment is not developed, then the maximum loss exposure related to TWH is limited to NW Holdings' equity investment balance, less its share of any cash or other assets available to NW Holdings as a 50% owner. The investment balance in TWH was $13.4 million at March 31, 2020 and 2019 and December 31, 2019. See Note 14 in the 2019 Form 10-K.

Other Investments

Other investments include financial investments in life insurance policies, which are accounted for at cash surrender value, net of policy loans. See Note 14 in the 2019 Form 10-K.

14. BUSINESS COMBINATIONS

2020 Business Combinations

During the three months ended March 31, 2020, NWN Water and its subsidiaries completed two acquisitions qualifying as business combinations. The aggregate fair value of the preliminary cash consideration transferred for these acquisitions was $38.1 million, most of which was preliminarily allocated to property, plant and equipment and goodwill. These transactions align with NW Holdings' water sector strategy as it continues to expand its water services territories in the Pacific Northwest and beyond and included:


•	Suncadia Water Company, LLC and Suncadia Environmental Company, LLC were acquired by NWN Water of Washington on January 31, 2020, and


•	T&W Water Service Company was acquired by NWN Water of Texas on March 2, 2020.

As each of these acquisitions met the criteria of a business combination, a preliminary allocation of the consideration to the acquired net assets based on their estimated fair value as of the acquisition date was performed. The allocation for each of these business combinations is considered preliminary as of March 31, 2020, as facts and circumstances that existed as of the acquisition date may be discovered as we continue to integrate these businesses. In accordance with U.S. GAAP, the fair value determination involves management judgment in determining the significant estimates and assumptions used and was made using existing regulatory conditions for net assets associated with Suncadia Water Company, LLC and T&W Water Service Company. We consider the preliminary purchase price allocation incomplete for Suncadia Environmental Company, LLC as information relevant to determining an estimated fair value was not available at the time the acquisition closed or as of March 31, 2020. Under these circumstances, the preliminary valuation was based on the books and records received from the seller. As a result, subsequent adjustments to the preliminary valuation of tangible assets, contract assets and liabilities, tax positions, and goodwill will likely be required. Subsequent adjustments are not expected to be significant, and any such adjustments are expected to be completed within the one-year measurement period for all acquisitions described above.

Table of Contents

Total preliminary goodwill of $19.1 million was recognized from the acquisitions described above. No intangible assets aside from goodwill were acquired. The goodwill recognized is attributable to the regulated water utility service territories, experienced workforces, and the strategic benefits from both the water and wastewater utilities expected from growth in their service territories. The total amount of goodwill that is expected to be deductible for income tax purposes is approximately $17.0 million. The acquisition costs associated with each business combination were expensed as incurred. The results of these business combinations were not material to the consolidated financial results of NW Holdings for the three months ended March 31, 2020.

2019 Business Combinations

Sunriver

On May 31, 2019, NWN Water of Oregon, a wholly-owned indirect subsidiary of NW Holdings, completed the acquisition of Sunriver Water, LLC and Sunriver Environmental, LLC (collectively referred to as Sunriver), a privately-owned water utility and wastewater treatment company located in Sunriver, Oregon that serves approximately 9,400 connections. The acquisition-date fair value of the total consideration transferred, after closing adjustments, was approximately $55.0 million in cash consideration. The transaction aligns with NW Holdings' water sector strategy as it continues to expand its water utility service territory in the Pacific Northwest and begins to pursue wastewater investment opportunities.

The Sunriver acquisition met the criteria of a business combination, and as such a preliminary allocation of the consideration to the acquired assets based on their estimated fair value as of the acquisition date was performed. In accordance with U.S. GAAP, the fair value determination was made using existing regulatory conditions for assets associated with Sunriver Water, LLC as well as existing market conditions and standard valuation approaches for assets associated with Sunriver Environmental, LLC in order to allocate value as determined by an independent third party assessor for certain assets, which involved the use of management judgment in determining the significant estimates and assumptions used by the assessor, with the remaining difference from the consideration transferred being recorded as goodwill. This allocation is considered preliminary as of March 31, 2020, as facts and circumstances that existed as of the acquisition date may be discovered as we continue to integrate Sunriver. As a result, subsequent adjustments to the preliminary valuation of tangible assets, tax positions, and goodwill may be required. Subsequent adjustments are not expected to be significant, and any such adjustments are expected to be completed within the one-year measurement period. The acquisition costs were expensed as incurred.

Preliminary goodwill of $40.4 million was recognized from this acquisition. The goodwill recognized is attributable to Sunriver's regulated water utility service territory, experienced workforce, and the strategic benefits for both the water utility and wastewater services expected from growth in its service territory. No intangible assets aside from goodwill were acquired. The total amount of goodwill that is expected to be deductible for income tax purposes is approximately $50.2 million.

The preliminary purchase price for the acquisition has been allocated to the net assets acquired as of the acquisition date and is as follows:



In thousands	May 31, 2019
Current assets	$	222
Property, plant and equipment	13,565
Goodwill	40,355
Deferred tax assets	828
Current liabilities	(22		)
Total net assets acquired	$	54,948

The amount of Sunriver revenues included in NW Holdings' consolidated statements of comprehensive income is $1.5 million for the three months ended March 31, 2020. Earnings from Sunriver operations for the three months ended March 31, 2020 were not material to the results of NW Holdings.

Other Business Combinations

During 2019, NWN Water completed three additional acquisitions qualifying as business combinations. The aggregate fair value of the preliminary consideration transferred for these acquisitions was approximately $2.0 million. These business combinations were not significant to NW Holdings' results of operations.

Goodwill

NW Holdings allocates goodwill to reporting units based on the expected benefit from the business combination. We perform an annual impairment assessment of goodwill at the reporting unit level, or more frequently if events and circumstances indicate that goodwill might be impaired. An impairment loss is recognized if the carrying value of a reporting unit’s goodwill exceeds its fair value.

As a result of all acquisitions completed, total goodwill was $69.2 million as of March 31, 2020, $9.0 million as of March 31, 2019 and $49.9 million as of December 31, 2019. The increase in the goodwill balance was primarily due to additions associated with our acquisitions in the water sector. All of our goodwill is related to water and wastewater acquisitions and is included in the other

Table of Contents

category for segment reporting purposes. The annual impairment assessment of goodwill occurs in the fourth quarter of each year. There have been no impairments recognized to date.

15. DERIVATIVE INSTRUMENTS

NW Natural enters into financial derivative contracts to hedge a portion of the NGD segment's natural gas sales requirements. These contracts include swaps, options, and combinations of option contracts. These derivative financial instruments are primarily used to manage commodity price variability. A small portion of NW Natural's derivative hedging strategy involves foreign currency exchange contracts.

NW Natural enters into these financial derivatives, up to prescribed limits, primarily to hedge price variability related to physical gas supply contracts as well as to hedge spot purchases of natural gas. The foreign currency forward contracts are used to hedge the fluctuation in foreign currency exchange rates for pipeline demand charges paid in Canadian dollars.

In the normal course of business, NW Natural also enters into indexed-price physical forward natural gas commodity purchase contracts and options to meet the requirements of NGD customers. These contracts qualify for regulatory deferral accounting treatment.

NW Natural also enters into exchange contracts related to the third-party asset management of its gas portfolio, some of which are derivatives that do not qualify for hedge accounting or regulatory deferral, but are subject to NW Natural's regulatory sharing agreement. These derivatives are recognized in operating revenues, net of amounts shared with NGD customers.

Notional Amounts

The following table presents the absolute notional amounts related to open positions on NW Natural derivative instruments:



	March 31,				December 31,
In thousands	2020		2019		2019
Natural gas (in therms):
Financial	487,420		255,550		651,540
Physical	369,450		422,825		512,849
Foreign exchange	$	9,885	$	7,241	$	6,650

Purchased Gas Adjustment (PGA)

Derivatives entered into by NW Natural for the procurement or hedging of natural gas for future gas years generally receive regulatory deferral accounting treatment. In general, commodity hedging for the current gas year is completed prior to the start of the gas year, and hedge prices are reflected in the weighted-average cost of gas in the PGA filing. Rates and hedging approaches may vary between states due to different rate structures and mechanisms. Hedge contracts entered into after the start of the PGA period are subject to the PGA incentive sharing mechanism in Oregon. NW Natural entered the 2019-20 and 2018-19 gas years with forecasted sales volumes hedged at 52% and 48% in financial swap and option contracts, and 19% and 24% in physical gas supplies, respectively. Hedge contracts entered into prior to the PGA filing in September 2019 were included in the PGA for the 2019-20 gas year. Hedge contracts entered into after the PGA filing, and related to subsequent gas years, may be included in future PGA filings and qualify for regulatory deferral.

Unrealized and Realized Gain/Loss

The following table reflects the income statement presentation for the unrealized gains and losses from NW Natural's derivative instruments, which also represents all derivative instruments at NW Holdings:



	Three Months Ended March 31,
	2020						2019
In thousands	Natural gas commodity			Foreign exchange			Natural gas commodity			Foreign exchange
Benefit (expense) to cost of gas	$	(5,343	)	$	(466	)	$	7,007		$	(89	)
Operating revenues (expense)	(2,433		)	—			2,367			—
Amounts deferred to regulatory accounts on balance sheet	7,405			466			(9,029		)	89
Total gain (loss) in pre-tax earnings	$	(371	)	$	—		$	345		$	—

UNREALIZED GAIN/LOSS. Outstanding derivative instruments related to regulated NGD operations are deferred in accordance with regulatory accounting standards. The cost of foreign currency forward and natural gas derivative contracts are recognized immediately in the cost of gas; however, costs above or below the amount embedded in the current year PGA are subject to a regulatory deferral tariff and therefore, are recorded as a regulatory asset or liability.

Table of Contents

REALIZED GAIN/LOSS. NW Natural realized net losses of $2.1 million for the three months ended March 31, 2020, from the settlement of natural gas financial derivative contracts, whereas, net gains of $11.3 million were realized for the three months ended March 31, 2019. Realized gains and losses offset the higher or lower cost of gas purchased with differences refunded to or collected from customers in the following year through the PGA.

Credit Risk Management of Financial Derivatives Instruments

No collateral was posted with or by NW Natural counterparties as of March 31, 2020 or 2019. NW Natural attempts to minimize the potential exposure to collateral calls by diversifying counterparties to manage liquidity risk. Counterparties generally allow a certain credit limit threshold before requiring NW Natural to post collateral against loss positions. Given NW Natural's counterparty credit limits and portfolio diversification, it was not subject to collateral calls in 2020 or 2019. The collateral call exposure is set forth under credit support agreements, which generally contain credit limits.

NW Natural could also be subject to collateral call exposure where it has agreed to provide adequate assurance, which is not specific as to the amount of credit limit allowed, but could potentially require additional collateral in the event of a material adverse change. If credit-risk related contingent features within these contracts were triggered as of March 31, 2020, assuming current current gas prices and a credit rating downgrade to a speculative level, we could have been required to post $2.1 million in collateral calls, including estimates for adequate assurance.

NW Natural's financial derivative instruments are subject to master netting arrangements; however, they are presented on a gross basis in the consolidated balance sheets. NW Natural and its counterparties have the ability to set-off obligations to each other under specified circumstances. Such circumstances may include a defaulting party, a credit change due to a merger affecting either party, or any other termination event.

NW Natural’s current commodity financial swap and option contracts outstanding reflect unrealized losses of $0.2 million at March 31, 2020 and unrealized losses of $0.5 million at March 31, 2019. If netted by counterparty, NW Natural's physical and financial derivative position would result in an asset of $3.0 million and a liability of $4.3 million as of March 31, 2020, an asset of $6.4 million and a liability of $2.0 million as of March 31, 2019, and an asset of $9.4 million and a liability of $1.9 million as of December 31, 2019.

NW Natural is exposed to derivative credit and liquidity risk primarily through securing fixed price natural gas commodity swaps with financial counterparties. NW Natural utilizes master netting arrangements through International Swaps and Derivatives Association contracts to minimize this risk along with collateral support agreements with counterparties based on their credit ratings. In certain cases, NW Natural requires guarantees or letters of credits from counterparties to meet its minimum credit requirement standards. See Note 16 in the 2019 Form 10-K for additional information.

Fair Value

In accordance with fair value accounting, NW Natural includes non-performance risk in calculating fair value adjustments. This includes a credit risk adjustment based on the credit spreads of NW Natural counterparties when in an unrealized gain position, or on NW Natural's own credit spread when in an unrealized loss position. The inputs in our valuation models include natural gas futures, volatility, credit default swap spreads and interest rates. Additionally, the assessment of non-performance risk is generally derived from the credit default swap market and from bond market credit spreads. The impact of the credit risk adjustments for all outstanding derivatives was immaterial to the fair value calculation at March 31, 2020. Using significant other observable or Level 2 inputs, the net fair value was a liability of $1.3 million, an asset of $4.4 million, and an asset of $7.5 million as of March 31, 2020 and 2019, and December 31, 2019, respectively. No Level 3 inputs were used in our derivative valuations, and there were no transfers between Level 1 or Level 2 during the three months ended March 31, 2020 and 2019. See Note 2 in the 2019 Form 10-K.

16. ENVIRONMENTAL MATTERS

NW Natural owns, or previously owned, properties that may require environmental remediation or action. The range of loss for environmental liabilities is estimated based on current remediation technology, enacted laws and regulations, industry experience gained at similar sites, and an assessment of the probable level of involvement and financial condition of other potentially responsible parties (PRPs). When amounts are prudently expended related to site remediation of those sites described herein, NW Natural has recovery mechanisms in place to collect 96.68% of remediation costs allocable to Oregon customers and 3.32% of costs allocable to Washington customers.

These sites are subject to the remediation process prescribed by the Environmental Protection Agency (EPA) and the Oregon Department of Environmental Quality (ODEQ). The process begins with a remedial investigation (RI) to determine the nature and extent of contamination and then a risk assessment (RA) to establish whether the contamination at the site poses unacceptable risks to humans and the environment. Next, a feasibility study (FS) or an engineering evaluation/cost analysis (EE/CA) evaluates various remedial alternatives. It is at this point in the process when NW Natural is able to estimate a range of remediation costs and record a reasonable potential remediation liability, or make an adjustment to the existing liability. From this study, the regulatory agency selects a remedy and issues a Record of Decision (ROD). After a ROD is issued, NW Natural would seek to

Table of Contents

negotiate a consent decree or consent judgment for designing and implementing the remedy. NW Natural would have the ability to further refine estimates of remediation liabilities at that time.

Remediation may include treatment of contaminated media such as sediment, soil and groundwater, removal and disposal of media, institutional controls such as legal restrictions on future property use, or natural recovery. Following construction of the remedy, the EPA and ODEQ also have requirements for ongoing maintenance, monitoring and other post-remediation care that may continue for many years. Where appropriate and reasonably known, NW Natural will provide for these costs in the remediation liabilities described below.

Due to the numerous uncertainties surrounding the course of environmental remediation and the preliminary nature of several site investigations, in some cases, NW Natural may not be able to reasonably estimate the high end of the range of possible loss. In those cases, the nature of the possible loss has been disclosed, as has the fact that the high end of the range cannot be reasonably estimated where a range of potential loss is available. Unless there is an estimate within the range of possible losses that is more likely than other cost estimates within that range, NW Natural records the liability at the low end of this range. It is likely changes in these estimates and ranges will occur throughout the remediation process for each of these sites due to the continued evaluation and clarification concerning responsibility, the complexity of environmental laws and regulations and the determination by regulators of remediation alternatives. In addition to remediation costs, NW Natural could also be subject to Natural Resource Damages (NRD) claims. NW Natural will assess the likelihood and probability of each claim and recognize a liability if deemed appropriate. Refer to "Other Portland Harbor" below.

Environmental Sites

The following table summarizes information regarding liabilities related to environmental sites, which are recorded in other current liabilities and other noncurrent liabilities in NW Natural's balance sheet:

PORTLAND HARBOR SITE. The Portland Harbor is an EPA listed Superfund site that is approximately 10 miles long on the Willamette River and is adjacent to NW Natural's Gasco uplands site. NW Natural is one of over one hundred PRPs, each jointly and severally liable, at the Superfund site. In January 2017, the EPA issued its Record of Decision, which selects the remedy for the clean-up of the Portland Harbor site (Portland Harbor ROD). The Portland Harbor ROD estimates the present value total cost at approximately $1.05 billion with an accuracy between -30% and +50% of actual costs.

NW Natural's potential liability is a portion of the costs of the remedy for the entire Portland Harbor Superfund site. The cost of that remedy is expected to be allocated among more than one hundred PRPs. NW Natural is participating in a non-binding allocation process with the other PRPs in an effort to resolve its potential liability. The Portland Harbor ROD does not provide any additional clarification around allocation of costs among PRPs; accordingly, NW Natural has not modified any of the recorded liabilities at this time as a result of the issuance of the Portland Harbor ROD.

NW Natural manages its liability related to the Superfund site as two distinct remediation projects: the Gasco/Siltronic Sediments and Other Portland Harbor projects.

Table of Contents

Gasco/Siltronic Sediments. In 2009, NW Natural and Siltronic Corporation entered into a separate Administrative Order on Consent with the EPA to evaluate and design specific remedies for sediments adjacent to the Gasco uplands and Siltronic uplands sites. NW Natural submitted a draft EE/CA to the EPA in May 2012 to provide the estimated cost of potential remedial alternatives for this site. In March 2020, NW Natural and the EPA amended the Administrative Order on Consent to include additional remedial design activities downstream of the Gasco sediments site and in the navigation channel. Siltronic Corporation is not a party to the amended order. At this time, the estimated costs for the various sediment remedy alternatives in the draft EE/CA for the additional studies and design work needed before the cleanup can occur, and for regulatory oversight throughout the cleanup range from $54.7 million to $350 million. NW Natural has recorded a liability of $54.7 million for the Gasco sediment clean-up, which reflects the low end of the range. At this time, we believe sediments at the Gasco sediments site represent the largest portion of NW Natural's liability related to the Portland Harbor site discussed above.

Other Portland Harbor. While we believe liabilities associated with the Gasco/Siltronic sediments site represent NW Natural's largest exposure, there are other potential exposures associated with the Portland Harbor ROD, including NRD costs and harborwide remedial design and cleanup costs (including downstream petroleum contamination), for which allocations among the PRPs have not yet been determined.

NW Natural and other parties have signed a cooperative agreement with the Portland Harbor Natural Resource Trustee council to participate in a phased NRD assessment to estimate liabilities to support an early restoration-based settlement of NRD claims. One member of this Trustee council, the Yakama Nation, withdrew from the council in 2009, and in 2017, filed suit against NW Natural and 29 other parties seeking remedial costs and NRD assessment costs associated with the Portland Harbor site, set forth in the complaint. The complaint seeks recovery of alleged costs totaling $0.3 million in connection with the selection of a remedial action for the Portland Harbor site as well as declaratory judgment for unspecified future remedial action costs and for costs to assess the injury, loss or destruction of natural resources resulting from the release of hazardous substances at and from the Portland Harbor site. The Yakama Nation has filed two amended complaints addressing certain pleading defects and dismissing the State of Oregon. On the motion of NW Natural and certain other defendants the federal court has stayed the case pending the outcome of the non-binding allocation proceeding discussed above. NW Natural has recorded a liability for NRD claims which is at the low end of the range of the potential liability; the high end of the range cannot be reasonably estimated at this time. The NRD liability is not included in the aforementioned range of costs provided in the Portland Harbor ROD.

GASCO UPLANDS SITE. A predecessor of NW Natural, Portland Gas and Coke Company, owned a former gas manufacturing plant that was closed in 1958 (Gasco site) and is adjacent to the Portland Harbor site described above. The Gasco site has been under investigation by NW Natural for environmental contamination under the ODEQ Voluntary Cleanup Program (VCP). It is not included in the range of remedial costs for the Portland Harbor site noted above. The Gasco site is managed in two parts, the uplands portion and the groundwater source control action.

NW Natural submitted a revised Remedial Investigation Report for the uplands to ODEQ in May 2007. In March 2015, ODEQ approved Remedial Assessment (RA) for this site, enabling commencement of work on the FS in 2016. NW Natural has recognized a liability for the remediation of the uplands portion of the site which is at the low end of the range of potential liability; the high end of the range cannot be reasonably estimated at this time.

In October 2016, ODEQ and NW Natural agreed to amend their VCP agreement to incorporate a portion of the Siltronic property adjacent to the Gasco site formerly owned by Portland Gas & Coke between 1939 and 1960 into the Gasco RA and FS, excluding the uplands for Siltronic. Previously, NW Natural was conducting an investigation of manufactured gas plant constituents on the entire Siltronic uplands for ODEQ. Siltronic will be working with ODEQ directly on environmental impacts to the remainder of its property.

In September 2013, NW Natural completed construction of a groundwater source control system, including a water treatment station, at the Gasco site. NW Natural has estimated the cost associated with the ongoing operation of the system and has recognized a liability which is at the low end of the range of potential cost. NW Natural cannot estimate the high end of the range at this time due to the uncertainty associated with the duration of running the water treatment station, which is highly dependent on the remedy determined for both the upland portion as well as the final remedy for Gasco sediment exposure.

OTHER SITES. In addition to those sites above, NW Natural has environmental exposures at three other sites: Central Service Center, Front Street and Oregon Steel Mills. NW Natural may have exposure at other sites that have not been identified at this time. Due to the uncertainty of the design of remediation, regulation, timing of the remediation and in the case of the Oregon Steel Mills site, pending litigation, liabilities for each of these sites have been recognized at their respective low end of the range of potential liability; the high end of the range could not be reasonably estimated at this time.

Central Service Center site. The investigative phase to characterize the existing site has been completed and determined by the Oregon Department of Environmental Quality (DEQ) to be sufficient to allow for the issuance of a Conditional No Further Action (cNFA). NW Natural is now conducting ongoing environmental monitoring activities over the next 5 years in order to meet the conditions which were included within the cNFA.

Table of Contents

Front Street site. The Front Street site was the former location of a gas manufacturing plant NW Natural operated (the former Portland Gas Manufacturing site, or PGM). At ODEQ’s request, NW Natural conducted a sediment and source control investigation and provided findings to ODEQ. In December 2015, an FS on the former Portland Gas Manufacturing site was completed.

In July 2017, ODEQ issued the PGM ROD. The ROD specifies the selected remedy, which requires a combination of dredging, capping, treatment, and natural recovery. In addition, the selected remedy also requires institutional controls and long-term inspection and maintenance. NW Natural revised its estimate of the remaining cost to construct the remedy in the first quarter of 2020 to approximately $9.8 million. Further, NW Natural has recognized an additional liability of $0.9 million for design costs, regulatory and permitting issues, and post-construction work. NW Natural currently plans to construct the remedy in 2020.

Environmental Cost Deferral and Recovery

NW Natural has authorizations in Oregon and Washington to defer costs related to remediation of properties that are owned or were previously owned by NW Natural. In Oregon, a Site Remediation and Recovery Mechanism (SRRM) is currently in place to recover prudently incurred costs allocable to Oregon customers, subject to an earnings test. On October 21, 2019 the WUTC authorized an Environmental Cost Recovery Mechanism (ECRM) for recovery of prudently incurred costs allocable to Washington customers beginning November 1, 2019. See Note 18 in the 2019 Form 10-K for a description of SRRM and ECRM collection processes.

The following table presents information regarding the total regulatory asset deferred:

⁽¹⁾	Includes pre-review and post-review deferred costs, amounts currently in amortization, and interest, net of amounts collected from customers.


⁽²⁾	Excludes 3.32% of the Front Street site liability, or $0.4 million in 2020 and $0.4 million in 2019, as the OPUC only allows recovery of 96.68% of costs for those sites allocable to Oregon, including those that historically served only Oregon customers.

⁽³⁾

Environmental costs relate to specific sites approved for regulatory deferral by the OPUC and WUTC. In Oregon, NW Natural earns a carrying charge on cash amounts paid, whereas amounts accrued but not yet paid do not earn a carrying charge until expended. It also accrues a carrying charge on insurance proceeds for amounts owed to customers. In Washington, neither the cash paid nor insurance proceeds received accrue a carrying charge. Current environmental costs represent remediation costs management expects to collect from customers in the next 12 months. Amounts included in this estimate are still subject to a prudence and earnings test review by the OPUC and do not include the $5.0 million tariff rider. The amounts allocable to Oregon are recoverable through NGD rates, subject to an earnings test.

ENVIRONMENTAL EARNINGS TEST. To the extent NW Natural earns at or below its authorized Return on Equity (ROE) as defined by the SRRM, remediation expenses and interest in excess of the $5.0 million tariff rider and $5.0 million insurance proceeds are recoverable through the SRRM. To the extent NW Natural earns more than its authorized ROE in a year, it is required to cover environmental expenses and interest on expenses greater than the $10.0 million with those earnings that exceed its authorized ROE.

Legal Proceedings

NW Holdings is not currently party to any direct claims or litigation, though in the future it may be subject to claims and litigation arising in the ordinary course of business.

NW Natural is subject to claims and litigation arising in the ordinary course of business including the matters discussed above and ordinary course claims and litigation noted below. Although the final outcome of any of these legal proceedings cannot be predicted with certainty, including the matter described below, NW Natural and NW Holdings do not expect that the ultimate disposition of any of these matters will have a material effect on financial condition, results of operations or cash flows.

17. DISCONTINUED OPERATIONS

NW Holdings

On June 20, 2018, NWN Gas Storage, then a wholly-owned subsidiary of NW Natural, entered into a Purchase and Sale Agreement (the Agreement) that provides for the sale by NWN Gas Storage of all of the membership interests in Gill Ranch. Gill Ranch owns a 75% interest in the natural gas storage facility located near Fresno, California known as the Gill Ranch Gas Storage Facility. Pacific Gas and Electric Company (PG&E) owns the remaining 25% interest in the Gill Ranch Gas Storage Facility. The CPUC regulates Gill Ranch under a market-based rate model which allows for the price of storage services to be set by the marketplace.

The Agreement provides for an initial cash purchase price of $25.0 million (subject to a working capital adjustment), plus potential additional payments to NWN Gas Storage of up to $26.5 million in the aggregate if Gill Ranch achieves certain economic performance levels for the first three full gas storage years (April 1 of one year through March 31 of the following year) occurring after the closing and the remaining portion of the gas storage year during which the closing occurs.

The sale of Gill Ranch was approved by the CPUC in December 2019, and the transaction is subject to other customary closing conditions and covenants, including the requirement that all of the representations and warranties be true and correct as of the closing date except, as would not, in the case of certain representations and warranties, be reasonably expected to have a material adverse effect on Gill Ranch. The Agreement, as amended, was subject to termination by either party if the transaction had not closed by March 31, 2020. On March 20, 2020, NWN Gas Storage and the buyer amended the Agreement to change the date after which the Agreement would be subject to termination by either party from March 31, 2020 to May 15, 2020.

The following table presents the carrying amounts of the major components of Gill Ranch that are classified as discontinued operations assets and liabilities on the consolidated balance sheets:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is management’s assessment of NW Holdings' and NW Natural's financial condition, including the principal factors that affect results of operations. The discussion refers to the consolidated results from continuing operations for the three months ended March 31, 2020 and 2019 of NW Holdings, the substantial majority of which consist of the operating results of NW Natural. See Note 1 for a complete list of NW Holdings' and NW Natural's direct and indirect wholly owned subsidiaries. When significant activity exists at NW Holdings that does not exist at NW Natural, additional disclosure has been provided. References in this discussion to "Notes" are to the Notes to Unaudited Consolidated Financial Statements in this report. A significant portion of the business results are seasonal in nature, and, as such, the results of operations for the three month periods are not necessarily indicative of expected fiscal year results. Therefore, this discussion should be read in conjunction with NW Holdings' and NW Natural's 2019 Annual Report on Form 10-K, as applicable (2019 Form 10-K).

NW Natural's natural gas distribution activities are reported in the natural gas distribution (NGD) segment. The NGD segment includes our NW Natural local gas distribution business, NWN Gas Reserves, which is a wholly owned subsidiary of Energy Corp, and the NGD-portion of NW Natural's Mist storage facility in Oregon. Other activities aggregated and reported as other at NW Natural include the non-NGD storage activity at Mist as well as asset management services and the appliance retail center operations. Other activities aggregated and reported as other at NW Holdings include NWN Energy's equity investment in Trail West Holding, LLC (TWH), which is pursuing the development of a proposed natural gas pipeline through its wholly owned subsidiary, Trail West Pipeline, LLC (TWP); NNG Financial's investment in Kelso-Beaver Pipeline (KB Pipeline); and NWN Water, which through itself or its subsidiaries owns and continues to pursue investments in the water sector. See Note 4 for further discussion of our business segment and other, as well as our direct and indirect wholly owned subsidiaries.

NON-GAAP FINANCIAL MEASURES. In addition to presenting the results of operations and earnings amounts in total, certain financial measures are expressed in cents per share, which are non-GAAP financial measures. All references in this section to earnings per share (EPS) are on the basis of diluted shares. We use such non-GAAP financial measures to analyze our financial performance because we believe they provide useful information to our investors and creditors in evaluating our financial condition and results of operations. Our non-GAAP financial measures should not be considered a substitute for, or superior to, measures calculated in accordance with U.S. GAAP.

EXECUTIVE SUMMARY

We manage our business and strategic initiatives with a long-term view of providing natural gas service safely and reliably to customers, working with regulators on key policy initiatives, and remaining focused on growing our business. See "2020 Outlook" in the 2019 Form 10-K for more information. Current operational highlights include:


•	Continue to provide customers with essential natural gas and water utility services during the COVID-19 pandemic;


•	NGD business added over 12,000 meters during the past twelve months for a growth rate of 1.6% at March 31, 2020;


•	Filed an all-party partial settlement in NW Natural's 2020 Oregon general rate case related to cost of capital; and


•	Closed four water utility transactions in 2020 bringing our total connections to approximately 25,000.

Key year-to-date financial highlights for NW Holdings include:

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. Net income from continuing operations increased $4.9 million and $5.3 million at NW Holdings and NW Natural, respectively, and was primarily due to the following factors, all of which occurred at NW Natural:

•

a $1.5 million increase in NGD margin driven by new customer rates, primarily from the 2019 Washington rate case that went into effect on November 1, 2019 and customer growth, and revenues from the NW Natural's North Mist storage contract, partially offset by the effects of 9% warmer than average weather in 2020 compared to 9% colder than average weather in 2019. In addition, margin decreased due to revenues recognized in 2019 associated with recoveries of NW Natural's pension balancing account which did not recur in 2020;


•	a $12.5 million reduction from pension expenses recognized in 2019 associated with recoveries of NW Natural's pension balancing account which did not recur in 2020, with $4.6 million reflected in operations and maintenance expense and $7.9 million reflected in other income (expense), net;


•	a $10.5 million reduction in expenses due to a regulatory pension disallowance in 2019, which did not recur in 2020 with $3.9 million reflected in operations and maintenance expense and $6.6 million recorded in other income (expense), net, offset by


•	a $5.7 million increase in NGD income tax expense which was primarily the result of higher pretax income in the current period. The prior period also included an income tax benefit related to the regulatory pension disallowance;


•	a $3.5 million decrease in deferred regulatory interest income in other income (expense), net, of which $3.8 million relates to interest income recognized in 2019 associated with the 2019 recoveries of the pension balancing account;


•	a $3.2 million increase in operations and maintenance expenses primarily related to higher compensation and benefit costs as well as additional non-payroll expenses related to contractor services;


•	a $2.8 million increase in expenses associated with the amortization of the pension balancing account that NW Natural began recovering in April 2019 with $1.0 million recorded in operations and maintenance expense and $1.8 million in other income (expense), net;


•	a $2.7 million increase in NGD depreciation expense due to plant additions; and


•	a $1.8 million decrease in revenues from non-NGD gas storage operations at Mist as a result of less favorable market conditions.

COVID-19 AND CURRENT ECONOMIC CONDITIONS. The novel coronavirus (COVID-19), which was declared a pandemic by the World Health Organization in March 2020, has resulted in severe and widespread global, national, and local economic and societal disruptions. On March 23, 2020, the Governors of Oregon and Washington, the states in which NW Natural’s service territories are located, issued stay at home executive orders. These and subsequent executive orders required the closure of “non-essential” businesses and permitted the continuation of “essential services.” All of the services provided by NW Natural are considered “essential services” under the Oregon executive order, and currently all services provided by NW Natural are

Table of Contents

considered “essential services” under the Washington executive orders. Our water businesses are similarly considered "essential" by the states in which we operate.

As a critical infrastructure energy company that provides an essential service to our customers, NW Natural has well-defined emergency response command structures and protocols. In response to the pandemic, NW Natural mobilized its incident command team and business continuity plans in early March, and continues to operate under these structures and protocols, with a focus on the safety of our 1,200 employees and the 2.5 million people, business partners and communities we serve. NW Natural has suspended business travel out of territory and implemented work-from-home plans for employees wherever possible. For employees whose role requires them to work in the field, we are following CDC, OSHA, and state specific guidance. Measures include: following social distancing guidelines; use of personal protective equipment (PPE) including masks, face coverings and gloves; enhanced sanitizing protocols; limiting non-essential in-home services; and other measures intended to mitigate the spread of this disease and keep our employees and customers safe and informed. Our water companies are following similar protocols.

Our water and natural gas utility businesses continue to serve our customers without interruption. To support our customers in this unusual time, in mid-March, NW Natural voluntarily and temporarily stopped charging late fees and disconnecting customers for nonpayment. NW Natural also filed a request with regulators to provide Oregon natural gas customers with their annual June bill credit totaling approximately $17 million related to NW Natural's revenue sharing mechanism. NW Natural has applied for regulatory deferrals in the states in which it operates to recover COVID-19 related costs such as bad debt expense, lost revenues related to late fees and reconnection fees, and other COVID-19 related costs. Our water companies have taken similar actions.

Additionally, in March, as a precaution to strengthen our liquidity and guard against volatile markets during the COVID-19 pandemic, we took the following steps:


•	NW Natural drew $227 million on its credit facility and NW Holdings drew $35 million on its credit facility;


•	NW Natural secured a $150 million 364-day term loan due March 22, 2021 and borrowed the full amount;


•	NW Natural held commercial paper of $73 million at March 31, 2020; and


•	NW Natural issued $150 million 30-year first mortgage bonds with an interest rate of 3.6% at NW Natural.

With these financings secured, NW Holdings held $471.1 million of cash as of March 31, 2020 on a consolidated basis, and NW Natural held $432.3 million of cash on a stand-alone basis. With these financings, both companies currently have ample liquidity to manage their respective cash needs.

The federal CARES Act was signed into law on March 27, 2020 to provide direct and indirect financial support to individuals, businesses, state and local governments, and the healthcare system in response to COVID-19. While we anticipate that the support the CARES Act provides to our customers may indirectly benefit NW Holdings and NW Natural, we cannot measure this benefit. However, we do not anticipate the CARES Act to have a material financial effect on NW Holdings or NW Natural. As provided for in the CARES Act, we do plan to delay remittance of the employer portion of the Social Security payroll tax through the end of 2020.

We have taken additional actions in response to known issues arising from the trends related to COVID-19 pandemic. For example, we have enhanced cybersecurity monitoring in response to reports that cybersecurity attackers are more active with much of the economy utilizing work from home protocols. Like others, we have experienced some constraints on our ability to obtain PPE and disinfecting supplies, but currently believe that we have sufficient supplies to continue our work and are actively working to procure additional supplies and most efficiently utilize those supplies we have on hand. We have not experienced material disruptions in our supply chain for other goods and services to date, but are continuing to actively monitor, and are prepared to formulate contingency plans as necessary. Additionally, while some public utility commissions have announced delays in dockets as a result of COVID-19, we currently expect that NW Natural’s Oregon general rate case will proceed on the expected schedule with rates effective November 2020.

The timing of the onset of the COVID-19 pandemic and resulting economic disruption in the United States coincided with end of the Pacific Northwest peak winter heating season. The majority of our national gas utility volumes are delivered during the first and fourth quarters, and volumes naturally decline in the spring with a significant reduction of heating loads in the summer and into the fall. Therefore, for the period ending March 31, 2020, we did not see significant effects of the COVID-19 pandemic or economic slowdown on key business metrics such as gas volumes delivered, customer growth, meter disconnections, uncollectible accounts or lost revenues. Similarly, at March 31, 2020, our capital projects were continuing to move forward as planned, with only a small portion of our construction activities affected by a temporary halt of construction in Washington from March 26, 2020 through April 24, 2020, which has subsequently reopened.

April was the first full month under the stay at home orders in our service territories and the effects of COVID-19 and the current economic conditions are not apparent at this time. We are actively monitoring the previously identified key metrics. While we are unable to predict with certainty the length, severity or impacts of the COVID-19 pandemic and economic disruptions on our business, we have the following expectations and beliefs currently:

Table of Contents


•	We expect the majority of our capital projects to continue to move forward with only a small portion of our construction activities affected by the temporary halt of residential construction in Washington, which has now lifted.

•

While we did not see a substantial increase in customer bad debts in the first quarter of 2020, we anticipate an increase to uncollectible accounts for bill cycles in March and April for service provided through March 31st. We have accounted for this in our allowance for Residential and Commercial uncollectible accounts estimate which increased from 0.105% of gas sales to approximately .157% of gas sales and for which we will seek regulatory recovery.


•	NW Natural had not seen a substantial reduction in overall sales volumes as of March 31, 2020. We may see declines in volumes during the second quarter as the effects of the stay at home orders become more apparent. However, volumes do not translate directly to earnings as the majority of our NGD margin is not dependent on volumes.

•

NW Natural had not experienced significant meter disconnections as of March 31, 2020. We are closely monitoring our approximately 71,000 commercial and industrial natural gas meters, as a substantial decline in these meters could materially affect margin in 2020. A disconnection may occur if circumstances require businesses, such as restaurants, retail, and those in the hospitality sector, to permanently close. We don't anticipate significant residential meter disconnections.


•	NW Natural had not seen a significant reduction in new meter connections as of March 31, 2020. However, a significant recession or prolonged economic slowdown could result in a decline in new meter connections, which could adversely affect margin in late 2020 and the following periods.

On April 20, 2020, the Oregon Governor in conjunction with the West Coast coalition of governors, issued a preliminary high-level framework for reopening the Oregon economy, which is expected to be finalized in early May. The framework outlines a phased approach to lifting restrictions after the State experiences a declining number of COVID-19 cases, adequate hospital capacity, robust testing and sufficient supplies of PPE among other things. The Washington Governor is similarly planning a reopening of the Washington economy. We will closely monitor the timing of these reopenings, their impact on our local economies, and their effects on our business. Currently, we believe the key 2020 financial effects from COVID-19, if any, will depend on the magnitude of commercial and industrial sales meter losses; lost revenues from lower late charge and reconnection fees, bad debt expense from uncollectible customer accounts, and other COVID-19 costs, if these costs and expenses are not recoverable in rates; and a significant reduction in new meters.

Given the evolving nature of the pandemic and resulting economic conditions, we are continually monitoring our business operations and the larger trends and developments to take additional measures we believe are warranted to continue providing safe and reliable service to our customers and communities while protecting our employees.

See the discussion in "Results of Operations" below for additional detail regarding all significant activity that occurred during the first quarter of 2020.

Regulation and Rates

NATURAL GAS DISTRIBUTION. NW Natural's natural gas distribution business is subject to regulation by the OPUC and WUTC with respect to, among other matters, rates and terms of service, systems of accounts, and issuances of securities by NW Natural. In 2019, approximately 88% of NGD customers were located in Oregon, with the remaining 12% in Washington. Earnings and cash flows from natural gas distribution operations are largely determined by rates set in general rate cases and other proceedings in Oregon and Washington. They are also affected by weather, the local economies in Oregon and Washington, the pace of customer growth in the residential, commercial, and industrial markets, and NW Natural's ability to remain price competitive, control expenses, and obtain reasonable and timely regulatory recovery of its natural gas distribution-

related costs, including operating expenses and investment costs in plant and other regulatory assets. See "Most Recent Completed General Rate Cases" below.

MIST INTERSTATE GAS STORAGE. NW Natural's interstate storage activity at Mist is subject to regulation by the OPUC, WUTC, and the Federal Energy Regulatory Commission (FERC) with respect to, among other matters, rates and terms of service. The OPUC also regulates the intrastate storage services at Mist, while FERC regulates the interstate storage services at Mist. The FERC uses a maximum cost of service model which allows for gas storage prices to be set at or below the cost of service as approved by each agency in their last regulatory filing. The OPUC Schedule 80 rates are tied to the FERC rates, and are updated whenever NW Natural modifies FERC maximum rates.

OTHER. In June 2018, NWN Gas Storage, a wholly-owned subsidiary of NW Holdings, entered into a Purchase and Sale Agreement for the sale of all of its ownership interests in Gill Ranch, a natural gas storage facility located near Fresno, California. The sale was approved by the CPUC in December 2019 and is subject to other customary closing conditions. See Note 17 for more information. The wholly owned regulated water businesses of NWN Water, a wholly owned subsidiary of NW Holdings, are subject to regulation by the utility commissions in the states in which they are located, which currently includes Oregon, Washington, Idaho, and Texas.

Most Recent Completed General Rate Cases

OREGON. Effective November 1, 2018, the OPUC authorized rates to customers based on an ROE of 9.4%, an overall rate of return of 7.317%, and a capital structure of 50% common equity and 50% long-term debt. In March 2019, the OPUC issued an order resolving the remaining matters of the rate case regarding recovery of NW Natural's pension balancing account and the return of tax reform benefits to customers. For additional information, see "Rate Mechanisms - Pension Cost Deferral and Pension Balancing Account" and "Rate Mechanism - Tax Reform Deferral" below. On December 30, 2019, NW Natural filed a general rate case in Oregon. For more information, see "Regulatory Proceeding Updates - 2020 Oregon Rate Case" below.

WASHINGTON. Effective November 1, 2019, the WUTC authorized rates to customers based on an ROE of 9.40% and an overall rate of return of 7.161% with a capital structure of 49% common equity, 1% short-term debt, and 50% long-term debt. The WUTC also authorized the recovery of environmental remediation expenses allocable to Washington customers through an Environmental Cost Recovery Mechanism (ECRM) and directed NW Natural to provide federal tax reform benefits to customers. See "Rate Mechanisms - Environmental Cost Deferral and Recovery - Washington ECRM" and "Rate Mechanisms - Tax Reform Deferral" below.

From January 1, 2009, through October 31, 2019, the WUTC authorized rates to customers based on an ROE of 10.1% and an overall rate of return of 8.4% with a capital structure of 51% common equity, 5% short-term debt, and 44% long-term debt.

FERC. NW Natural is required under its Mist interstate storage certificate authority and rate approval orders to file every five years either a petition for rate approval or a cost and revenue study to change or justify maintaining the existing rates for its interstate storage services. On October 12, 2018, NW Natural filed a rate petition with FERC for revised maximum cost-based rates, which incorporated the new federal corporate income tax rate. The revised rates were effective beginning November 1, 2018.

NW Natural continuously evaluates the need for rate cases in its jurisdictions. For additional information, see "Regulatory Proceeding Updates - Rate Case" below.

PURCHASED GAS ADJUSTMENT. Rate changes are established for NW Natural each year under PGA mechanisms in Oregon and Washington to reflect changes in the expected cost of natural gas commodity purchases. The PGA filings include gas costs under spot purchases as well as contract supplies, gas costs hedged with financial derivatives, gas costs from the withdrawal of storage inventories, the production of gas reserves, interstate pipeline demand costs, temporary rate adjustments, which amortize balances of deferred regulatory accounts, and the removal of temporary rate adjustments effective for the previous year.

Typically, each year NW Natural hedges gas prices on a portion of NW Natural's annual sales requirement based on normal weather, including both physical and financial hedges. NW Natural entered the 2019-20 gas year with its forecasted sales volumes hedged at 52% in financial swap and option contracts, including hedging of 56% for Oregon and 24% for Washington, and 19% in physical gas supplies, including hedging of 20% for Oregon and 14% for Washington.

As of March 31, 2020, NW Natural was hedged at approximately 35% for the 2020-21 gas year, with Oregon at 37% and Washington at 20%. NW Natural is also hedged between 1% and 20% for annual requirements over the subsequent five gas years, which consists of between 2% and 22% for Oregon and between 0% and 10% for Washington. Hedge levels are subject to change based on actual load volumes, which depend to a certain extent on weather, economic conditions, and estimated gas reserve production. Also, gas storage inventory levels may increase or decrease with storage expansion, changes in storage contracts with third parties, variations in the heat content of the gas, and/or storage recall by NW Natural.

In September 2019, NW Natural filed its annual PGA and received OPUC and WUTC approval in October 2019. PGA rate changes were effective November 1, 2019. Rates and hedging approaches vary between states due to different rate structures and mechanisms. In addition, as required with the Washington PGA filing, NW Natural incorporated and began implementing risk-responsive hedging strategies for the 2019-20 PGA for its Washington gas supplies.

Under the current PGA mechanism in Oregon, there is an incentive sharing provision whereby NW Natural is required to select each year an 80% deferral or a 90% deferral of higher or lower actual gas costs compared to estimated PGA prices, such that the impact on NW Natural's current earnings from the incentive sharing is either 20% or 10% of the difference between actual and estimated gas costs, respectively. For the 2018-19 and 2019-20 gas years, NW Natural selected the 90% deferral option. Under the Washington PGA mechanism, NW Natural defers 100% of the higher or lower actual gas costs, and those gas cost differences are passed on to customers through the annual PGA rate adjustment.

EARNINGS TEST REVIEW. NW Natural is subject to an annual earnings review in Oregon to determine if the NGD business is earning above its authorized ROE threshold. If NGD business earnings exceed a specific ROE level, then 33% of the amount above that level is required to be deferred or refunded to customers. Under this provision, if NW Natural selects the 80% deferral gas cost option, then NW Natural retains all earnings up to 150 basis points above the currently authorized ROE. If NW Natural selects the 90% deferral option, then it retains all earnings up to 100 basis points above the currently authorized ROE. For the 2018-19 and 2019-20 gas years, NW Natural selected the 90% deferral option. The ROE threshold is subject to adjustment annually based on movements in long-term interest rates. For calendar year 2019, the ROE threshold was 10.24%. NW Natural filed the 2019 earnings test on May 1, 2020 and does not expect a customer refund adjustment for 2019 based on results.

GAS RESERVES. In 2011, the OPUC approved the Encana gas reserves transaction to provide long-term gas price protection for NGD business customers and determined costs under the agreement would be recovered on an ongoing basis through the annual PGA mechanism. Gas produced from NW Natural's interests is sold at then prevailing market prices, and revenues from such sales, net of associated operating and production costs and amortization, are included in cost of gas. The cost of gas, including a carrying cost for the rate base investment made under the original agreement, is included in NW Natural's annual Oregon PGA filing, which allows NW Natural to recover these costs through customer rates. The net investment under the original agreement earns a rate of return.

In 2014, NW Natural amended the original gas reserves agreement in response to Encana's sale of its interest in the Jonah field located in Wyoming to Jonah Energy. Under the amended agreement with Jonah Energy, NW Natural has the option to invest in additional wells on a well-by-well basis with drilling costs and resulting gas volumes shared at the amended proportionate working interest for each well in which NW Natural invests. Volumes produced from the additional wells drilled after the amended agreement are included in NW Natural's Oregon PGA at a fixed rate of $0.4725 per therm. NW Natural has not participated in additional wells since 2014.

DECOUPLING. In Oregon, NW Natural has a decoupling mechanism. Decoupling is intended to break the link between earnings and the quantity of gas consumed by customers, removing any financial incentive to discourage customers’ efforts to conserve energy. The Oregon decoupling mechanism was reauthorized and the baseline expected usage per customer was reset in the 2018 Oregon general rate case. This mechanism employs a use-per-customer decoupling calculation, which adjusts margin revenues to account for the difference between actual and expected customer volumes. The margin adjustment resulting from differences between actual and expected volumes under the decoupling component is recorded to a deferral account, which is included in the annual PGA filing.

WARM. In Oregon, NW Natural has an approved weather normalization mechanism, which is applied to residential and commercial customer bills. This mechanism is designed to help stabilize the collection of fixed costs by adjusting residential and commercial customer billings based on temperature variances from average weather, with rate decreases when the weather is colder than average and rate increases when the weather is warmer than average. The mechanism is applied to bills from December through mid-May of each heating season. The mechanism adjusts the margin component of customers’ rates to reflect average weather, which uses the 25-year average temperature for each day of the billing period. Daily average temperatures and 25-year average temperatures are based on a set point temperature of 59 degrees Fahrenheit for residential customers and 58 degrees Fahrenheit for commercial customers. The collections of any unbilled WARM amounts due to tariff caps and floors are deferred and earn a carrying charge until collected, or returned, in the PGA the following year. Residential and commercial customers in Oregon are allowed to opt out of the weather normalization mechanism, and as of March 31, 2020, 8% of total eligible customers had opted out. NW Natural does not have a weather normalization mechanism approved for residential and commercial Washington customers, which account for about 12% of total customers. See "Business Segment—Natural Gas Distribution" below.

INDUSTRIAL TARIFFS. The OPUC and WUTC have approved tariffs covering NGD service to major industrial customers, which are intended to give NW Natural certainty in the level of gas supplies needed to serve this customer group. The approved terms include, among other things, an annual election period, special pricing provisions for out-of-cycle changes, and a requirement that industrial customers complete the term of their service election under NW Natural's annual PGA tariff.

ENVIRONMENTAL COST DEFERRAL AND RECOVERY. NW Natural has authorizations in Oregon and Washington to defer costs related to remediation of properties that are owned or were previously owned by NW Natural. In Oregon, a Site Remediation and Recovery Mechanism (SRRM) is currently in place to recover prudently incurred costs allocable to Oregon customers, subject to an earnings test. Effective beginning November 1, 2019, the WUTC authorized an Environmental Cost Recovery Mechanism (ECRM) for recovery of prudently incurred costs allocable to Washington customers.

Oregon SRRM

Under the Oregon SRRM collection process there are three types of deferred environmental remediation expense:


•	Pre-review - This class of costs represents remediation spend that has not yet been deemed prudent by the OPUC. Carrying costs on these remediation expenses are recorded at NW Natural's authorized cost of capital. NW Natural anticipates the prudence review for annual costs and approval of the earnings test prescribed by the OPUC to occur by the third quarter of the following year.


•	Post-review - This class of costs represents remediation spend that has been deemed prudent and allowed after applying the earnings test, but is not yet included in amortization. NW Natural earns a carrying cost on these amounts at a rate equal to the five-year treasury rate plus 100 basis points.

•

Amortization - This class of costs represents amounts included in current customer rates for collection and is calculated as one-fifth of the post-review deferred balance. NW Natural earns a carrying cost equal to the amortization rate determined annually by the OPUC, which approximates a short-term borrowing rate. NW Natural included $5.1 million and $6.1 million of deferred remediation expense approved by the OPUC for collection during the 2019-20 and 2018-19 PGA years, respectively.

In addition, the SRRM also provides for the annual collection of $5.0 million from Oregon customers through a tariff rider. As it collects amounts from customers, NW Natural recognizes these collections as revenue net of any earnings test adjustments and

Table of Contents

separately amortizes an equal and offsetting amount of the deferred regulatory asset balance through the environmental remediation operating expense line shown separately in the operating expenses section of the Consolidated Statements of Comprehensive Income. For additional information, see Note 18 in the 2019 Form 10-K.

The SRRM earnings test is an annual review of adjusted NGD ROE compared to authorized NGD ROE. To apply the earnings test NW Natural must first determine what if any costs are subject to the test through the following calculation:

Annual spend

Less: $5.0 million base rate rider

Prior year carry-over⁽¹⁾

$5.0 million insurance + interest on insurance

Total deferred annual spend subject to earnings test

Less: over-earnings adjustment, if any

Add: deferred interest on annual spend⁽²⁾

Total amount transferred to post-review


⁽¹⁾	Prior year carry-over results when the prior year amount transferred to post-review is negative. The negative amount is carried over to offset annual spend in the following year.


⁽²⁾	Deferred interest is added to annual spend to the extent the spend is recoverable.

To the extent the NGD business earns at or below its authorized ROE as defined in the SRRM, the total amount transferred to post-review is recoverable through the SRRM. To the extent more than authorized ROE is earned in a year, the amount transferred to post-review would be reduced by those earnings that exceed its authorized ROE.

NW Natural concluded there was no earnings test adjustment for 2019 based on the environmental earnings test that was submitted in May 2020.

Washington ECRM

The ECRM established by the WUTC order effective November 1, 2019 permits NW Natural’s recovery of environmental remediation expenses allocable to Washington customers. These expenses represent 3.32% of costs associated with remediation of sites that historically served both Oregon and Washington customers. The order allows for recovery of past deferred and future prudently incurred remediation costs allocable to Washington through application of insurance proceeds and collections from customers. Prudently incurred costs that were deferred from the initial deferral authorization in February 2011 through June 2019 are to be fully offset with insurance proceeds, with any remaining insurance proceeds to be amortized over a 10.5 year period. On an annual basis NW Natural will file for a prudence determination and a request to recover remediation expenditures in excess of insurance amortizations in the following year's customer rates. After insurance proceeds are fully amortized, if in a particular year the request to collect deferred amounts exceeds one percent of Washington normalized revenues, then the excess will be collected over three years with interest.

PENSION COST DEFERRAL AND PENSION BALANCING ACCOUNT. From 2011 through October 2018, the OPUC authorized a regulatory mechanism in which NW Natural deferred annual pension expenses above the amount set in rates, with recovery of these deferred amounts through the implementation of a balancing account, which included the expectation of higher and lower pension expenses in future years. During this period the mechanism permitted NW Natural to accrue interest on the account balance at the NGD business' authorized rate of return. The OPUC ordered the freezing of the account in October 2018 with pension expenses to be recovered through rates beginning November 1, 2018.

In March 2019 the OPUC issued an order outlining how the account would be recovered. As a result, the following items were recorded in the first quarter of 2019:


•	Applied $7.1 million of TCJA benefits deferred from January 1, 2018 to October 31, 2018, as a reduction against the pension balancing account;


•	Credited to customers' benefit $5.4 million of deferred income taxes as a reduction against the pension balancing account;


•	Reduced the amount of the frozen balancing account by an additional $10.5 million; and


•	Reduced the interest rate on the pension balancing account from NW Natural's authorized rate of return of 7.317% to 4.3%.

The items above resulted in the recovery of $12.5 million of deferred pension expenses by applying deferred tax benefits against the pension balancing account. Recognition of these items resulted in higher operations and maintenance expense and other income (expense), net with offsetting benefits recognized in operating revenues and income tax expense. Additional pension expenses of $10.5 million from the regulatory disallowance were also recognized in operations and maintenance expense and other income (expense), net. Deferred regulatory interest income of $3.8 million was also realized in other income (expense), net in 2019.

Commencing April 1, 2019, the OPUC also authorized the collection of the remainder of the pension balancing account over ten years in a customer tariff of $7.3 million per year. Deferred pension expense recoveries were $2.8 million for the three months ended March 31, 2020.

Table of Contents

TAX REFORM DEFERRAL. In December 2017, NW Natural filed applications with the OPUC and WUTC to defer the overall net benefit associated with the TCJA that was enacted on December 22, 2017. In February 2019, NW Natural and the other parties to the 2018 Oregon rate case agreed upon terms by which the deferred benefits would be returned to customers via a joint stipulation filed with the OPUC. In March 2019, the OPUC approved the terms in their entirety as follows:


•	Applied $7.1 million of TCJA benefits deferred from January 1, 2018 to October 31, 2018, as a reduction against the pension balancing account and


•	Credited to customers' benefit $5.4 million of deferred income taxes as a reduction against the pension balancing account.

Commencing April 1, 2019, the OPUC also ordered the following:


•	Provide an annual credit to base rates of $3.4 million for excess deferred income taxes to all customers, subject to the average rate assumption method;


•	Provide an additional annual credit of $3.0 million to sales service customers for five years; and


•	An increase in rate base of $15.4 million, and corresponding increase to revenue requirement of $1.4 million.

If NW Natural files a general rate case within five years of the date of the March 2019 order, this revenue requirement may be adjusted as part of that general rate case.

On October 21, 2019 the WUTC issued an order dictating the means by which deferred tax reform benefits would be returned to customers beginning November 1, 2019. The order directs NW Natural to provide customers with a rate reduction of $2.1 million over one year to reflect the benefit of the lower federal corporate income tax rate accumulating from January 1, 2018 through October 31, 2019, and provides an additional annual rate reduction initially set at approximately $0.5 million to reflect a benefit from the remeasurement of deferred tax liabilities of approximately $15.0 million.

INTERSTATE STORAGE AND ASSET MANAGEMENT SHARING. On an annual basis, NW Natural credits amounts to Oregon and Washington customers as part of a regulatory incentive sharing mechanism related to net revenues earned from Mist gas storage and asset management activities. Generally, amounts are credited to Oregon customers in June, while credits are given to customers in Washington as reductions in rates through the annual PGA filing in November.

Regulatory Proceeding Updates

During 2020, NW Natural was involved in the regulatory activities discussed below. For additional information, see Part II, Item 7 "Results of Operations—Regulatory Matters" in the 2019 Form 10-K.

COVID-19 DEFERRALS. NW Natural filed applications at the OPUC and WUTC requesting authorization to use deferred accounting to defer costs associated with the COVID-19 public health emergency. NW Natural Water’s subsidiaries with regulated utilities are also pursuing deferred accounting treatment with their respective utility commissions. Costs deferred may include but are not limited to the following: personal protective equipment for employees as they provide essential services, additional cleaning and/or sanitation expenses, bad debt, and other related financial impacts.

2020 OREGON RATE CASE. On December 30, 2019, NW Natural filed a request for a general rate increase with the OPUC. The filing included a requested $71.4 million annual revenue requirement increase based a capital structure of 50% debt and 50% equity; a return on equity of 10.0%; cost of capital of 7.298%; and average rate base of $1.47 billion, which reflects an increase of $269.9 million since the last rate case.

On March 12, 2020, NW Natural, the OPUC staff, the Oregon Citizens’ Utility Board, and the Alliance of Western Energy Consumers, which comprise all of the parties to the rate case, filed a settlement with the OPUC which addresses cost of capital issues in the case (Settlement). Under the Settlement, the parties agree to an overall cost of capital of 6.965%, which is based on an approved capital structure of 50% equity and 50% long-term debt, and a return on equity of 9.4%. The Settlement does not address other aspects of the rate case, such as the average rate base or the overall annual revenue requirement increase. The Settlement is subject to the review and approval of the OPUC. For new rates to be effective, the OPUC must issue an order, which may approve or deny the terms of the Settlement or be issued under the OPUC’s own terms with respect to the cost of capital and which would address other elements of the rate case. NW Natural expects new rates to take effect November 1, 2020. Although it is possible that continued workforce closures could delay the proceeding, we do not currently anticipate any delays to this schedule.

RENEWABLE NATURAL GAS. On June 19, 2019, the Oregon legislature passed Senate Bill 98 (SB98), which enables natural gas utilities to procure or develop renewable natural gas (RNG) on behalf of their Oregon customers. RNG is produced from organic materials like food, agricultural and forestry waste, wastewater, or landfills. Methane is captured from these organic materials as they decompose and is conditioned to pipeline quality, so it can be added into the existing natural gas system, reducing net greenhouse gas emissions.

Table of Contents

SB98 outlines the following parameters for the RNG program including: setting out broad targets for gas utilities that allow for the purchase of RNG from third parties such that 30% of the gas distributed to retail customers is RNG by 2050; allowing gas utilities to invest in RNG infrastructure for the production, processing, pipeline interconnection and distribution of RNG to their customers; and creating a limit of 5% of a utility's revenue requirement that can be used to cover the incremental cost of RNG to protect utilities and ratepayers from increased costs as the RNG market develops.

The bill was signed into law by the governor in July 2019 and subsequently in August the OPUC opened a docket. We are currently working with parties on the rulemaking for the bill, which is expected to conclude with the OPUC adopting rules by July 31, 2020. We do not currently anticipate any delays to this schedule.

CORPORATE ACTIVITY TAX. In 2019, the State of Oregon enacted a Corporate Activity Tax (CAT) that is applicable to all businesses with annual Oregon gross revenue in excess of $1 million. The CAT is in addition to the state's corporate income tax and imposes a 0.57% tax on certain Oregon gross receipts less a reduction for a portion of cost of goods sold or labor. The CAT legislation became effective September 29, 2019 and applies to calendar years beginning January 1, 2020. On December 23, 2019, NW Natural filed an application with the OPUC to allow us to defer this additional expense, with recovery of these deferred amounts to be determined in future rate case proceedings. As of March 31, 2020 NW Natural had deferred $2.0 million related to this tax.

WATER UTILITIES. In 2020, NW Holdings, through its water subsidiaries, continued acquiring water utilities. The following transactions received regulatory approval and were closed during the first quarter of 2020:


•	Suncadia Water Company, LLC and Suncadia Environmental, LLC — NWN Water of Washington received regulatory approval for the purchase of Suncadia Water in January 2020. Suncadia Environmental is not subject to the WUTC's jurisdiction. The transaction closed in January 2020.


•	T&W Water Service Company — NWN Water of Texas received regulatory approval from the Public Utility Commission of Texas for the T&W Water Service Company acquisition in February 2020 and subsequently the transaction closed in March 2020.

OREGON EXECUTIVE ORDER. On March 10, 2020, the governor of Oregon issued an executive order establishing greenhouse gas (GHG) emissions reduction goals of at least 45% below 1990 emission levels by 2035 and at least 80% below 1990 emission levels by 2050 and directing state agencies and commissions to facilitate such GHG emission goals. Although the order does not specifically direct actions of natural gas distribution businesses, the OPUC is directed to prioritize proceedings and activities that advance decarbonization in the utility sector, mitigate energy burden experienced by utility customers and ensure system reliability and resource adequacy. The executive order also directs other agencies to cap and reduce GHG emissions from transportation fuels and all other liquid and gaseous fuels, including natural gas, adopt building energy efficiency goals for new building construction, reduce methane gas emissions from landfills and food waste, and submit a proposal for adoption of state goals for carbon sequestration and storage by Oregon’s forest, wetlands and agricultural lands. As an executive order, any implementation is reliant on state agency rule-making. The scope and content of any state commission or agency rules, as well as the time to propose, adopt and implement any such rules, has not been determined. The executive order and any resulting rules and agencies’ jurisdiction and authority with respect to those rules are likely to be subject to legal challenge from a variety of stakeholders.

Business Segment - Natural Gas Distribution (NGD)

NGD margin results are primarily affected by customer growth, revenues from rate-base additions, and, to a certain extent, by changes in delivered volumes due to weather and customers’ gas usage patterns. In Oregon, NW Natural has a conservation tariff (also called the decoupling mechanism), which adjusts margin up or down each month through a deferred regulatory accounting adjustment designed to offset changes resulting from increases or decreases in average use by residential and commercial customers. NW Natural also has a weather normalization tariff in Oregon, WARM, which adjusts customer bills up or down to offset changes in margin resulting from above- or below-average temperatures during the winter heating season. Both mechanisms are designed to reduce, but not eliminate, the volatility of customer bills and natural gas distribution earnings. For additional information, see Part II, Item 7 "Results of Operations—Regulatory Matters—Rate Mechanisms" in NW Natural's 2019 Form 10-K. In addition to NW Natural's local gas distribution business, the NGD segment also includes the portion of the Mist underground storage facility used to serve NGD customers, the North Mist gas storage expansion, and NWN Gas Reserves, which is a wholly owned subsidiary of Energy Corp.

The NGD business is primarily seasonal in nature due to higher gas usage by residential and commercial customers during the cold winter heating months. Other categories of customers experience seasonality in their usage but to a lesser extent. Seasonality affects the comparability of the results of operations of the NGD business across quarters but not across years.

⁽¹⁾See Natural Gas Distribution Margin Table below for additional detail

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. The primary factors contributing to the $6.7 million, or $0.15 per share, increase in NGD net income were as follows:


•	a $1.5 million increase in NGD margin due to:


•	a $5.0 million increase due to new customer rates, primarily from the 2019 Washington rate case that went into effect on November 1, 2019 and customer growth;


•	a $4.9 million increase from revenue generated from NW Natural's North Mist storage contract which commenced service in May 2019 and is included within other regulated services within NGD margin; partially offset by,


•	a $2.0 million decrease driven by 9% warmer than average weather in the first quarter of 2020 compared to 9% colder than average weather in the prior period partially offset by a benefit from gas cost incentive sharing; and,


•	a $7.1 million decrease due to revenues recognized in 2019 associated with recoveries of NW Natural's pension balancing account, which were entirely offset by pension expenses within operations and maintenance expense and other income (expense), net in the first quarter of 2019.

In addition to the increase in margin, NGD net income for the first quarter of 2020 reflects:


•	a benefit of $12.5 million from pension expenses recognized in 2019 associated with recoveries of NW Natural's pension balancing account which did not recur in 2020. Approximately $4.6 million was recorded operations and maintenance expense and $7.9 million was recorded in other income (expense), net;


•	a benefit of $10.5 million from a 2019 regulatory pension disallowance which did not recur in 2020. Approximately $3.9 million was recorded in operations and maintenance expense and $6.6 million was recorded in other income (expense), net; partially offset by,


•	$5.7 million higher income tax expense which was primarily the result of higher pretax income in the current period. The prior period also included an income tax benefit related to the regulatory pension disallowance;


•	a $4.1 million increase in NGD operations and maintenance expense primarily associated with higher payroll and benefit costs and included $1.0 million of regulatory amortization of the pension balancing account which began in April 2019 and is ongoing;


•	a $3.5 million decrease in deferred regulatory interest income in other income (expense), net, of which $3.8 million relates to interest income recognized in 2019 associated with the 2019 recoveries of the pension balancing account;


•	a $2.7 million increase in depreciation expense due to NGD plant additions, including the North Mist gas storage facility; and


•	a $1.1 million decrease in other income and expense, net driven by $1.8 million of regulatory amortization expense of the pension balancing account which began in April 2019 and is ongoing.

See "Results of Operations - Regulatory Matters - Regulatory Proceeding Updates" above and Note 9 for more information regarding the pension balancing account.

Table of Contents

For the three months ended March 31, 2020, total NGD volumes sold and delivered decreased 6% over the same period in 2019 primarily due to 9% warmer than average weather in the first quarter of 2020 compared to 9% colder than average weather in the prior period.

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. Other regulated services margin increased $4.9 million primarily due to the commencement of storage services at the North Mist expansion facility in May 2019. See Note 6 for information regarding North Mist expansion lease accounting.

Other

Other activities aggregated and reported as other at NW Natural include the non-NGD storage activity at Mist as well as asset management services and the appliance retail center operations. Other activities aggregated and reported as other at NW Holdings include NWN Energy's equity investment in Trail West Holding, LLC (TWH), which is pursuing the development of a proposed natural gas pipeline through its wholly-owned subsidiary, Trail West Pipeline, LLC (TWP); NNG Financial's investment in Kelso-Beaver Pipeline (KB Pipeline); and NWN Water, which owns and continues to pursue investments in the water sector. See Note 4 for further discussion of our business segment and other, as well as our direct and indirect wholly-owned subsidiaries, and Note 13 for further details on our investment in TWH.

The following table presents the results of activities aggregated and reported as other for both NW Holdings and NW Natural:

NW Holdings other - net income	$	333		$	2,212		$	(1,879	)
EPS - NW Holdings - other	$	0.01		$	0.08		$	(0.07	)

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. Other net income decreased $1.9 million at NW Holdings and decreased $1.5 million at NW Natural. The decrease at NW Natural was primarily due to lower revenues from non-NGD gas storage operations at Mist as a result of less favorable market conditions and higher operations and maintenance costs, partially offset by lower income taxes. The decrease at NW Holdings was driven by the decrease at NW Natural as well as an increase in interest expense due to various financings undertaken as a precaution to increase liquidity in response to the COVID-19 pandemic.

NW Holdings	$	48,921	$	51,482	$	(2,561	)

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. Operations and maintenance expense decreased by $2.6 million and $4.2 million at NW Holdings and NW Natural, respectively, primarily due to the following which occurred at NW Natural:


•	a $4.6 million decrease from 2019 pension expenses (service cost component) recognized due to the recovery of amounts in NW Natural's pension balancing account, which were primarily offset within NGD margin and income tax benefits and which did not recur in 2020;


•	a $3.9 million decrease from a 2019 regulatory pension disallowance (service cost component) as a result of the March 2019 OPUC order in the Oregon general rate case and which did not recur in 2020; partially offset by


•	a $1.0 million increase due to regulatory amortization of the pension balancing account, which began in April 2019 (service cost component) and is ongoing; and


•	a $3.2 million increase related to higher compensation and benefit costs as well as additional non-payroll expenses related to contractor services.

The $1.6 million increase in other NW Holdings operations and maintenance expense primarily reflects operating expenses from water companies that have been acquired.

Bad debt expense as a percent of revenues was 0.2% for the first three months of 2020 and 0.1% for the same period in 2019. The provision for uncollectible customer accounts was evaluated for its current expected credit losses following NW Holdings' and NW Natural's standard review process. For the period ended March 31, 2020, the provision was also evaluated for conditions and circumstances present due to the COVID-19 pandemic. See Note 2 for additional information.

Table of Contents


•	a $7.9 million decrease from 2019 pension expenses (non-service cost component) recognized due to the recovery of amounts in NW Natural's pension balancing account, which were primarily offset within NGD margin and income tax benefits and which did not recur in 2020;


•	a $6.6 million decrease from a 2019 regulatory pension disallowance (non-service cost component) as a result of the March 2019 OPUC order in the Oregon general rate case which did not recur in 2020; partially offset by


•	a $1.8 million decrease due to the regulatory amortization of the remaining pension balancing account deferral, which began in April 2019 and is ongoing; and,


•	a $3.5 million decrease in regulatory interest income, of which $3.8 million is related to the 2019 realization of the equity interest component of financing costs accrued on the pension balancing account as recovery of the deferral began in March 2019.

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. Income tax expense increased $5.5 million and $5.6 million at NW Holdings and NW Natural, respectively. The increase in income tax expense is primarily the result of higher pretax income in the current period. The prior period also included an income tax benefit related to the regulatory pension disallowance pursuant to the March 2019 OPUC order.

Pending Sale of Gill Ranch Storage

On June 20, 2018, NWN Gas Storage, a wholly owned subsidiary of NW Holdings, entered into a Purchase and Sale Agreement (the Sale Agreement) that provides for the sale by NWN Gas Storage of all of its membership interests in Gill Ranch. Gill Ranch owns a 75% interest in the natural gas storage facility located near Fresno, California known as the Gill Ranch Gas Storage Facility. PG&E owns the remaining 25% interest in the Gill Ranch Facility.

In the Sale Agreement, NWN Gas Storage makes representations and warranties concerning, among other things, Gill Ranch, the Gill Ranch Facility and Gill Ranch’s business and contractual relationships, and agrees to cause Gill Ranch to conduct its business and maintain its properties in the ordinary course, consistent with material agreements and past practice.

The Sale Agreement provides for an initial cash purchase price of $25.0 million (subject to a working capital adjustment), plus potential additional payments to NWN Gas Storage of up to $26.5 million in the aggregate if Gill Ranch achieves certain economic performance levels for the first three full gas storage years (April 1 of one year through March 31 of the following year) occurring after the closing and the remaining portion of the gas storage year during which the closing occurs.

Table of Contents

The decision approving the transaction was issued by the CPUC in December, 2019 and the transaction is subject to other customary closing conditions and covenants, including the requirement that all of the representations and warranties be true and correct as of the closing date except, as would not, in the case of certain representations and warranties, be reasonably expected to have a material adverse effect on Gill Ranch. The Sale Agreement, as amended, was subject to termination by either party if the transaction had not closed by March 31, 2020. On March 20, 2020, NWN Gas Storage and the buyer amended the Sale Agreement to change the date after which the Sale Agreement would be subject to termination by either party from March 31, 2020 to May 15, 2020. We continue to strive to close this transaction.

On January 29, 2019, PG&E filed voluntary petitions for relief under chapter 11 bankruptcy. We cannot fully predict the course of the bankruptcy proceedings or the impact on the sale and will continue to monitor the situation closely.

The results of Gill Ranch Storage have been determined to be discontinued operations and are presented separately, net of tax, from the results of continuing operations of NW Holdings for all periods presented. See Note 17 for more information on the Sale Agreement and the results of our discontinued operations.

The CPUC regulates Gill Ranch under a market-based rate model which allows for the price of storage services to be set by the marketplace. The CPUC also regulates the issuance of securities, system of accounts, and regulates intrastate storage services. The Geologic Energy Management Division of the California Department of Conservation regulations for gas storage wells were finalized in June 2018, and the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed new federal regulations for underground natural gas storage facilities, which were finalized during 2019 and increased costs for all storage providers. NW Holdings will continue to monitor and assess additional new regulations until the sale is complete.

Short-term liquidity for Gill Ranch is supported by cash balances, internal cash flow from operations, equity contributions from its parent company, and, if necessary, additional external financing.

FINANCIAL CONDITION

Capital Structure

NW Holdings' long-term goal is to maintain a strong and balanced consolidated capital structure. NW Natural targets a regulatory capital structure of 50% common equity and 50% long-term debt, which is consistent with approved regulatory allocations in Oregon, which has an allocation of 50% common equity and 50% long-term debt without recognition of short-term debt, and Washington, which has an allocation of 50% long-term debt, 1% short-term debt, and 49% common equity.

When additional capital is required, debt or equity securities are issued depending on both the target capital structure and market conditions. These sources of capital are also used to fund long-term debt retirements and short-term commercial paper maturities. See "Liquidity and Capital Resources" below and Note 8. Achieving our target capital structure and maintaining sufficient liquidity to meet operating requirements is necessary to maintain attractive credit ratings and provide access to the capital markets at reasonable costs.

NW Holdings' consolidated capital structure was as follows:



	March 31,				December 31,
	2020		2019		2019
Common equity	48.6	%	51.9	%	49.6	%
Long-term debt (including current maturities)	51.4		48.1		50.4
Total	100.0	%	100.0	%	100.0	%

NW Natural's consolidated capital structure was as follows:



	March 31,				December 31,
	2020		2019		2019
Common equity	48.3	%	50.4	%	49.3	%
Long-term debt (including current maturities)	51.7		49.6		50.7
Total	100.0	%	100.0	%	100.0	%

Including short-term debt balances, as of March 31, 2020 and 2019, and December 31, 2019, NW Holdings' consolidated capital structure included common equity of 37.5%, 46.5% and 45.7%; long-term debt of 39.6%, 37.0% and 42.5%; and short-term debt including current maturities of long-term debt of 22.9%, 16.5% and 11.8%, respectively. As of March 31, 2020 and 2019, and December 31, 2019, NW Natural's consolidated capital structure included common equity of 38.6%, 45.1%, and 45.9%; long-term debt of 41.2%, 38.0% and 42.9%; and short-term debt including current maturities of long-term debt of 20.2%, 16.9%, and 11.2%, respectively.

Liquidity and Capital Resources

At March 31, 2020 and 2019, NW Holdings had approximately $471.1 million and $12.8 million, and NW Natural had approximately $432.3 million and $6.8 million of cash and cash equivalents, respectively. In order to maintain sufficient liquidity during periods when capital markets are volatile, NW Holdings and NW Natural may elect to maintain higher cash balances and add short-term borrowing capacity. NW Holdings and NW Natural may also pre-fund their respective capital expenditures when long-term fixed rate environments are attractive.

As the COVID-19 pandemic developed, in early to mid-March, markets displayed significant volatility. In response to that volatility and possible implications for the availability of access to the capital markets, NW Natural and NW Holdings undertook a number of measures to increase cash on hand to ensure ample liquidity. On March 20, 2020, NW Natural borrowed $122.0 million under its multi-year credit facility, which was not backing commercial paper. On March 23, 2020, NW Natural entered into a $150.0 million, 364-day term loan credit agreement, and borrowed the full amount on closing. On March 31, 2020, NW Natural issued and sold $150.0 million aggregate principal amount of 3.60% First Mortgage Bonds. Similarly, on March 20, 2020, NW Holdings borrowed $35.0 million under its multi-year credit facility. These actions were taken as a precaution to support sufficient cash on hand under a variety of financial sector circumstances that could develop. Including these borrowings, NW Holdings and NW Natural expect to have ample liquidity in the form of cash on hand and from operations and available credit capacity under credit facilities to support funding needs. At March 31, 2020, NW Holdings had approximately $471.1 million of cash on hand on a consolidated basis, and NW Natural, on a standalone basis, had approximately $432.3 million of cash on hand.

NW Holdings

For NW Holdings, short-term liquidity is primarily provided by cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credit facility, and short-term credit facilities. NW Holdings also has a universal shelf registration statement filed with the SEC for the issuance of debt and equity securities. NW Holding's long-term debt, if any, and equity issuances are primarily used to provide equity contributions to NW Holdings’ operating subsidiaries for operating and capital expenditures and other corporate purposes. NW Holdings' issuance of securities is not subject to regulation by state public utility commissions, but the dividends from NW Natural to NW Holdings are subject to regulatory ring-fencing provisions. NW Holdings is a guarantor of its wholly owned subsidiary, NWN Water's $35.0 million two-year term loan agreement. See "Long-Term Debt" below for more information regarding NWN Water's debt.

As part of the ring-fencing conditions agreed upon with the OPUC and WUTC in connection with the holding company reorganization, NW Natural may not pay dividends or make distributions to NW Holdings if NW Natural’s credit ratings and common equity ratio, defined as the ratio of equity to long-term debt, fall below specified levels. If NW Natural’s long-term secured credit ratings are below A- for S&P and A3 for Moody’s, dividends may be issued so long as NW Natural’s common equity ratio is 45% or more. If NW Natural’s long term secured credit ratings are below BBB for S&P and Baa2 for Moody’s, dividends may be issued so long as NW Natural’s common equity ratio is 46% or more. Dividends may not be issued if NW Natural’s long-term secured credit ratings are BB+ or below for S&P or Ba1 or below for Moody’s, or if NW Natural’s common equity ratio is below 44%, where the ratio is measured using common equity and long-term debt excluding imputed debt or debt-like lease obligations. In each case, common equity ratios are determined based on a preceding or projected 13-month average. In addition, there are certain OPUC notice requirements for dividends in excess of 5% of NW Natural’s retained earnings.

Additionally, if NW Natural’s common equity (excluding goodwill and equity associated with non-regulated assets), on a preceding or projected 13-month average basis, is less than 46% of NW Natural’s capital structure not including short-term debt, NW Natural is required to notify the OPUC, and if the common equity ratio falls below 44%, file a plan with the OPUC to restore its equity ratio to 44%. This condition is designed to ensure NW Natural continues to be adequately capitalized under the holding company structure. Under the WUTC order, the average common equity ratio must not exceed 56%.

Based on several factors, including current cash reserves, committed credit facilities, its ability to receive dividends from its operating subsidiaries, in particular NW Natural, and an expected ability to issue long-term debt and equity securities in the capital markets, NW Holdings believes its liquidity is sufficient to meet anticipated near-term cash requirements, including all contractual obligations, investing, and financing activities as discussed in "Cash Flows" below.

At March 31, 2020, NW Natural satisfied the ring-fencing provisions described above.

NW HOLDINGS DIVIDENDS. Quarterly dividends have been paid on common stock each year since NW Holdings’ predecessor’s stock was first issued to the public in 1951. Annual common stock dividend payments per share, adjusted for stock splits, have increased each year since 1956. The declarations and amount of future dividends to shareholders will depend upon earnings, cash flows, financial condition, NW Natural’s ability to pay dividends to NW Holdings and other factors. The amount and timing of dividends payable on common stock is at the sole discretion of the NW Holdings Board of Directors.

Natural Gas Distribution Segment

For the NGD business segment, short-term borrowing requirements typically peak during colder winter months when the NGD business borrows money to cover the lag between natural gas purchases and bill collections from customers. Short-term liquidity for the NGD business is primarily provided by cash balances, internal cash flow from operations, proceeds from the sale of commercial paper notes, as well as available cash from multi-year credit facilities, short-term credit facilities, company-owned life

insurance policies, the sale of long-term debt, and equity contributions from NW Holdings. NW Natural's long-term debt and contributions from NW Holdings are primarily used to finance NGD capital expenditures, refinance maturing debt, and provide temporary funding for other general corporate purposes of the NGD business.

Based on its current debt ratings (see "Credit Ratings" below), NW Natural has been able to issue commercial paper and long-term debt at attractive rates and generally has not needed to borrow or issue letters of credit from its back-up credit facility. In the event NW Natural is not able to issue new debt due to adverse market conditions or other reasons, NW Natural expects that near-term liquidity needs can be met using internal cash flows, issuing commercial paper, receiving equity contributions from NW Holdings, or, for the NGD segment, drawing upon a committed credit facility. NW Natural also has a universal shelf registration statement filed with the SEC for the issuance of secured and unsecured debt securities. As previously described, NW Natural drew on its credit facility, secured a term loan, and issued FMBs to ensure ample liquidity during market volatility resulting from the COVID-19 pandemic.

In the event senior unsecured long-term debt ratings are downgraded, or outstanding derivative positions exceed a certain credit threshold, counterparties under derivative contracts could require NW Natural to post cash, a letter of credit, or other forms of collateral, which could expose NW Natural to additional cash requirements and may trigger increases in short-term borrowings while in a net loss position. NW Natural was not required to post collateral at March 31, 2020. If the credit risk-related contingent features underlying these contracts were triggered on March 31, 2020, assuming NW Natural's long-term debt ratings dropped to non-investment grade levels, it could have been required to post $2.1 million in collateral with counterparties. See "Credit Ratings" below and Note 15.

Other items that may have a significant impact on NW Natural's liquidity and capital resources include pension contribution requirements and environmental expenditures. For additional information, see Part II, Item 7 "Financial Condition" in the 2019 Form 10-K.

SHORT-TERM DEBT. The primary source of short-term liquidity for NW Holdings is cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credit facility, and short-term credit facilities it may enter into from time to time.

The primary source of short-term liquidity for NW Natural is from the sale of commercial paper and bank loans. NW Holdings and NW Natural have separate bank facilities, and NW Natural has a commercial paper program. In addition to issuing commercial paper or bank loans to meet working capital requirements, including seasonal requirements to finance gas purchases and accounts receivable, short-term debt may also be used to temporarily fund capital requirements. For NW Natural, commercial paper and bank loans are periodically refinanced through the sale of long-term debt or equity contributions from NW Holdings. Commercial paper, when outstanding, is sold through two commercial banks under an issuing and paying agency agreement and is supported by one or more unsecured revolving credit facilities. See “Credit Agreements” below.

On March 23, 2020, Northwest Natural Gas Company (NW Natural) entered into a $150.0 million 364-day term loan credit agreement. NW Natural borrowed the full amount thereunder. The proceeds of which are expected to be used for general corporate purposes and to provide additional liquidity. All principal and unpaid interest under the Term Loan is due and payable on March 22, 2021. NW Natural may prepay the principal and interest, and amounts prepaid may not be reborrowed. The Term Loan requires that NW Natural maintain credit ratings with Standard & Poor’s and Moody’s Investor Services. A change in NW Natural’s debt ratings may result in a change to the interest rate on the Term Loan but is not an event of default. The Term Loan requires NW Natural to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the banks to terminate their lending commitments and to accelerate the maturity of all amounts outstanding. NW Natural was in compliance with the covenant requiring the maintenance of an indebtedness to total capitalization ratio as of March 31, 2020 with a consolidated indebtedness to total capitalization ratio of 61.4%.

At March 31, 2020 and 2019, NW Holdings had short-term debt outstanding of $550.0 million and $176.4 million, respectively. At March 31, 2020 and 2019, NW Natural had short-term debt outstanding of $450.0 million and $176.3 million, respectively. The weighted average interest rate on short-term debt outstanding at March 31, 2020 was 2.0% and 1.7% at NW Holdings and NW Natural, respectively.

Credit Agreements

NW Holdings

NW Holdings has a $100 million credit agreement, with a feature that allows it to request increases in the total commitment amount up to a maximum of $150 million. The maturity date of the agreement is October 2, 2023, with available extensions of commitments for two additional one-year periods, subject to lender approval.

Table of Contents

All lenders under the agreement are major financial institutions with committed balances and investment grade credit ratings as of March 31, 2020 as follows:



In millions
Lender rating, by category	Loan Commitment
AA/Aa	$	100
Total	$	100

Based on credit market conditions, it is possible one or more lending commitments could be unavailable to NW Holdings if the lender defaulted due to lack of funds or insolvency; however, NW Holdings does not believe this risk to be imminent due to the lenders' strong investment-grade credit ratings, and because NW Holding has fully drawn $100.0 million under this credit facility.

The NW Holdings credit agreement permits the issuance of letters of credit in an aggregate amount of up to $40 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. The credit agreement requires NW Holdings to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Holdings was in compliance with this covenant at March 31, 2020 and 2019, with consolidated indebtedness to total capitalization ratios of 62.5% and 53.5%, respectively.

The agreement also requires NW Holdings to maintain debt ratings (which are defined by a formula using NW Natural's credit ratings in the event NW Holdings does not have a credit rating) with Standard & Poor's (S&P) and Moody's Investors Service, Inc. (Moody’s) and notify the lenders of any change in its senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Holdings' debt ratings by S&P or Moody’s is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding under the credit agreements are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreements when ratings are changed. NW Holdings does not currently maintain ratings with S&P or Moody's.

NW Natural

NW Natural has a $300 million credit agreement, with a feature that allows it to request increases in the total commitment amount up to a maximum of $450 million. The maturity date of the agreement is October 2, 2023, with an available extension of commitments for two additional one-year periods, subject to lender approval.

All lenders under the agreement are major financial institutions with committed balances and investment grade credit ratings as of March 31, 2020 as follows:

Based on credit market conditions, it is possible one or more lending commitments could be unavailable to NW Natural if the lender defaulted due to lack of funds or insolvency; however, NW Natural does not believe this risk to be imminent due to the lenders' strong investment-grade credit ratings. In addition, as of March 31, 2020, NW Natural had borrowed $227.0 million under this credit facility.

The NW Natural credit agreement permits the issuance of letters of credit in an aggregate amount of up to $60 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. There were no outstanding balances under this credit agreement at March 31, 2019. The credit agreement requires NW Natural to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Natural was in compliance with this covenant at March 31, 2020 and 2019, with consolidated indebtedness to total capitalization ratios of 61.4% and 54.9%, respectively.

The agreement also requires NW Natural to maintain credit ratings with S&P and Moody’s and notify the lenders of any change in NW Natural's senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Natural's debt ratings by S&P or Moody’s is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding under the agreement are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreement when ratings are changed. See "Credit Ratings" below.

CREDIT RATINGS. NW Holdings does not currently maintain ratings with S&P or Moody's. NW Natural's credit ratings are a factor of liquidity, potentially affecting access to the capital markets including the commercial paper market. NW Natural's credit ratings also have an impact on the cost of funds and the need to post collateral under derivative contracts. The following table summarizes NW Natural's current credit ratings:



	S&P	Moody's
Commercial paper (short-term debt)	A-1	P-2
Senior secured (long-term debt)	AA-	A2
Senior unsecured (long-term debt)	n/a	Baa1
Corporate credit rating	A+	n/a
Ratings outlook	Stable	Stable

The above credit ratings and ratings outlook are dependent upon a number of factors, both qualitative and quantitative, and are subject to change at any time. The disclosure of or reference to these credit ratings is not a recommendation to buy, sell or hold NW Holdings or NW Natural securities. Each rating should be evaluated independently of any other rating.

As part of the ring-fencing conditions agreed upon with the OPUC and WUTC in connection with the holding company reorganization, NW Holdings and NW Natural are required to maintain separate credit ratings, long-term debt ratings, and preferred stock ratings, if any.

LONG-TERM DEBT. In June 2019, NW Natural Water, a wholly-owned subsidiary of NW Holdings, entered into a new two-year term loan agreement for $35.0 million. The loan carried an interest rate of 1.82% at March 31, 2020, which is based upon the three-month LIBOR rate. The loan is guaranteed by NW Holdings and requires NW Holdings to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Holdings was in compliance with this covenant at March 31, 2020, with a consolidated indebtedness to total capitalization ratio of 62.5%.

In February 2020, NW Natural retired $75.0 million of FMBs with an interest rate of 5.37%. No other long-term debt was retired during the three months ended March 31, 2020. In March 2020, NW Natural issued $150.0 million of FMBs with an interest rate of 3.60%, due in 2050. No other long-term debt is scheduled to mature over the next twelve months as of March 31, 2020,

See Part II, Item 7, "Financial Condition—Contractual Obligations" in the 2019 Form 10-K for long-term debt maturing over the next five years.

BANKRUPTCY RING-FENCING RESTRICTIONS. As part of the ring-fencing conditions agreed upon with the OPUC and WUTC in connection with the holding company reorganization, NW Natural is required to have one director who is independent from NW Natural management and from NW Holdings and to issue one share of NW Natural preferred stock to an independent third party. NW Natural was in compliance with both of these ring-fencing provisions as of March 31, 2020. NW Natural may file a voluntary petition for bankruptcy only if approved unanimously by the Board of Directors of NW Natural, including the independent director, and by the holder of the preferred share.

Cash Flows

Operating Activities

Changes in operating cash flows are primarily affected by net income or loss, changes in working capital requirements, and other cash and non-cash adjustments to operating results.

Operating activity highlights include:



	Three Months Ended March 31,
In thousands	2020		2019		QTD Change
NW Holdings cash provided by operating activities	$	102,863	$	104,794	$	(1,931	)
NW Natural cash provided by operating activities	$	104,062	$	104,703	$	(641	)

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. The significant factors contributing to the $1.9 million and $0.6 million decrease in cash flows provided by operating activities at NW Holdings and NW Natural. The primary drivers for both registrants included a net decrease of $9.6 million in net deferred gas costs as the actual costs during the 2019-20 winter season were in line with estimates embedded in the PGA as opposed to gas costs in the 2018-19 winter season that were 14% above PGA estimates, partially offset by, a net increase of $9.1 million from associated receivables, inventories, and accounts payable, reflecting lower working capital requirements as overall gas deliveries were down in the current period due to 9% warmer than average weather in 2020 compared to 9% colder than average weather in 2019.

Additionally, during the three months ended March 31, 2020, NW Natural contributed $3.2 million to the NGD segment's qualified defined benefit pension plan, compared to $1.5 million for the same period in 2019. The amount and timing of future contributions will depend on market interest rates and investment returns on the plans' assets. For additional information, see Note 9.

NW Holdings and NW Natural have lease and purchase commitments relating to their operating activities that are financed with cash flows from operations. For additional information, see Part II, Item 7 "Financial Condition—Contractual Obligations" and Note 17 in the 2019 Form 10-K.

Investing Activities

Investing activity highlights include:



	Three Months Ended March 31,
In thousands	2020			2019			QTD Change
NW Holdings cash used in investing activities	$	(101,429	)	$	(51,056	)	$	(50,373	)
NW Natural cash used in investing activities	$	(61,640	)	$	(50,649	)	$	(10,991	)

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. Cash used in investing activities increased $50.4 million at NW Holdings and increased $11.0 million at NW Natural. The increase at NW Natural was primarily due to higher capital expenditures related to system replacements and enhancements and information technology projects. The additional increase at NW Holdings was due to $37.9 million in expenditures for water and wastewater utility acquisitions, net of cash acquired, in 2020 as there were no acquisitions completed during the first quarter of 2019.

NW Holdings' capital expenditures in 2020 are anticipated to be between $240 million and $280 million, of which between $230 million and $270 million are anticipated to occur at the NGD business. NW Holdings' largest subsidiary, NW Natural, expects to make a significant level of investments in its NGD segment in 2020 and through 2024. Over the five-year period from 2020 to 2024, the NGD segment is expected to invest $950 million to $1.1 billion in capital expenditures to support system reliability, customer growth, and operate effective technology for the business. NW Holdings' wholly owned water subsidiaries expect to invest in their facilities to support growth and upgrade their systems with $30 million to $40 million expected to be invested from 2020 to 2024. NW Holdings expects an immaterial amount of non-NGD capital investments for Gill Ranch and other activities in 2020 and through 2024.

Investments in our infrastructure during and after 2020 will depend largely on additional regulations, growth, and expansion opportunities.

Required funds for the investments are expected to be internally generated and/or financed with long-term debt or equity, as appropriate.

Financing Activities

Financing activity highlights include:



	Three Months Ended March 31,
In thousands	2020		2019			QTD Change
NW Holdings cash provided by financing activities	$	459,997	$	(53,554	)	$	513,551

NW Natural cash provided by financing activities	$	383,914	$	(55,168	)	$	439,082
NW Natural change in short-term debt & proceeds from term loan	324,900		(41,200		)	366,100
NW Natural change in long-term debt	75,000		—			75,000

THREE MONTHS ENDED MARCH 31, 2020 COMPARED TO MARCH 31, 2019. Cash provided by financing activities increased $513.6 million and increased $439.1 million at NW Holdings and NW Natural, respectively.

The increase in cash provided by financing activities at NW Natural was primarily driven by $366.1 million in higher borrowings on short-term debt facilities and long-term FMBs issued as a precaution to increase liquidity in response to the COVID-19 pandemic, partially offset by the retirement of $75 million in long term debt during the first quarter of 2020.

The additional increase in cash provided by financing activities at NW Holdings was primarily due to additional draws on NW Holdings' credit facility undertaken as a precaution to increase liquidity in response to the COVID-19 pandemic as well as to finance the water and wastewater utility acquisitions that closed during the first quarter of 2020.

Contingent Liabilities

Loss contingencies are recorded as liabilities when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable in accordance with accounting standards for contingencies. See “Application of Critical Accounting Policies and Estimates” in the 2019 Form 10-K. At March 31, 2020, NW Natural's total estimated liability related to environmental sites is $130.3 million. See "Results of Operations—Regulatory Matters—Rate Mechanisms—Environmental Costs" in the 2019 Form 10-K and Note 16.

Table of Contents

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

In preparing financial statements in accordance with U.S. GAAP, management exercises judgment in the selection and application of accounting principles, including making estimates and assumptions that affect reported amounts of assets, liabilities, revenues, expenses, and related disclosures in the financial statements. Management considers critical accounting policies to be those which are most important to the representation of financial condition and results of operations and which require management’s most difficult and subjective or complex judgments, including accounting estimates that could result in materially different amounts if reported under different conditions or if they used different assumptions. Our most critical estimates and judgments for both NW Holdings and NW Natural include accounting for:


•	regulatory accounting;


•	revenue recognition;


•	derivative instruments and hedging activities;


•	pensions and postretirement benefits;


•	income taxes;


•	environmental contingencies; and


•	impairment of long-lived assets and goodwill.

There have been no material changes to the information provided in the 2019 Form 10-K with respect to the application of critical accounting policies and estimates. See Part II, Item 7, "Application of Critical Accounting Policies and Estimates," in the 2019 Form 10-K. NW Holdings and NW Natural reviewed our critical accounting policies and estimates in light of the current COVID-19 pandemic and identified no significant changes to those policies and estimates were required. See Note 2 for the areas that had immaterial impacts due to COVID-19.

Management has discussed its current estimates and judgments used in the application of critical accounting policies with the Audit Committees of the Boards of NW Holdings and NW Natural. Within the context of critical accounting policies and estimates, management is not aware of any reasonably likely events or circumstances that would result in materially different amounts being reported. For a description of recent accounting pronouncements that could have an impact on financial condition, results of operations or cash flows, see Note 2.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

NW Holdings and NW Natural are exposed to various forms of market risk including commodity supply risk, commodity price risk, interest rate risk, foreign currency risk, credit risk and weather risk. This section describes NW Holdings' and NW Natural's exposure to these risks, as applicable. Management monitors and manages these financial exposures as an integral part of NW Holdings' and NW Natural's overall risk management program. No material changes have occurred related to disclosures about market risk for the three months ended March 31, 2020. For additional information, see Part II, Item 1A, “Risk Factors” in this report and Part II, Item 7A, “Quantitative and Qualitative Disclosures about Market Risk” in the 2019 Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

NW Holdings and NW Natural management, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, completed an evaluation of the effectiveness of the design and operation of disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the Exchange Act)). Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer of each registrant have concluded that, as of the end of the period covered by this report, disclosure controls and procedures were effective to ensure that information required to be disclosed by each such registrant and included in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission (SEC) rules and forms and that such information is accumulated and communicated to management of each registrant, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control Over Financial Reporting

NW Holdings and NW Natural management are responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f).

There have been no changes in NW Natural's or NW Holdings' internal control over financial reporting that occurred during the quarter ended March 31, 2020 that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting for NW Holdings and NW Natural. The statements contained in Exhibit 31.1, Exhibit 31.2, Exhibit 31.3, and Exhibit 31.4 should be considered in light of, and read together with, the information set forth in this Item 4(b).

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Other than the proceedings disclosed in Note 16 and those proceedings disclosed and incorporated by reference in Part I, Item 3, “Legal Proceedings” in the 2019 Form 10-K, we have only nonmaterial litigation, or litigation that occurs in the ordinary course of our business.

ITEM 1A. RISK FACTORS

The following additional risk factors are provided to update and supplement the risk factors previously disclosed in Part I, Item 1A, “Risk Factors,” of our 2019 Annual Report on Form 10-K and the information contained in this Quarterly Report on Form 10-Q and our other reports filed with the SEC.

PUBLIC HEALTH RISK. The recent novel coronavirus (COVID-19) pandemic is widespread, severe and unpredictable. The continuation of this outbreak and the resulting economic conditions, or the emergence of other epidemic or pandemic crises, could materially and adversely affect NW Holdings’ and NW Natural’s business, results of operations, or financial condition.

The novel coronavirus (COVID-19), which was declared a pandemic by the World Health Organization in March 2020, has resulted in widespread and severe global, national and local economic and societal disruptions. In late March, the Governors of Oregon and Washington issued “stay at home” executive orders requiring the closure of “non-essential” business and modifications to certain “essential” businesses. While most of NW Natural’s services are considered “essential” under existing executive orders, there is no guarantee they will continue to be classified as such. Additionally, while we have undertaken emergency response command structures and protocols, they may not be sufficient to adequately mitigate the effects of COVID-19 on our operations. Although as of March 31, 2020, our financial condition and results of operations had not been materially impacted as a result of the COVID-19 outbreak, the situation is rapidly evolving and dynamic and could ultimately adversely affect our business by, among other things:

• disrupting our access to capital markets or increasing costs of capital affecting our liquidity in the future;

• reducing demand for natural gas, particularly from commercial and industrial customers that may be considered “non-essential” businesses under current or future executive orders or other governmental action, or that are suffering slow-downs or ultimately close completely due to COVID-19 effects;

• reducing customer growth and new meter additions due to less economic, construction or conversion activity;

• subjecting us to legislative or prolonged administrative action that limits our ability to collect on overdue accounts or disconnect gas service for nonpayment, beyond a period of time acceptable to us;

• increasing our operating costs for emergency supplies, personal protective equipment, cleaning services and supplies, remote technology and other specific needs during this crisis;

• impacting our capital expenditures if construction activities are deemed “non-essential” services and suspended or delayed;

• sickening or causing a mandatory quarantine of a large percentage of our workforce, or key workgroups with specialized skill sets, impairing our ability to perform key business functions or execute our business continuity plans;

• adversely affecting the asset values of NW Natural’s defined benefit pension plan or causing a failure to maintain sustained growth in pension investments over time, increasing our contribution requirements;

• limiting or curtailing entirely, public utility commissions’ ability to approve or authorize applications or other requests we may make with respect to our regulated businesses;

• impairing the functioning of our supply chain or ability to rely on third parties or business partners; and

• creating additional cybersecurity vulnerabilities due to heavy reliance on remote working in our business continuity model.

Additionally, the effects of COVID-19 could create prolonged unfavorable economic conditions, slowed economic growth, or an economic recession that may result in or be accompanied by unprecedented unemployment rates and declines in the value of homes and investment assets, adversely affecting the income and financial resources of many domestic households and businesses. It is unclear whether governmental responses to these conditions will lessen the severity or duration of any

economic downturn. Our operational and financial results would likely be affected by such economic conditions. Less new housing construction, fewer conversions to natural gas, higher levels of residential foreclosures and vacancies, and personal and business bankruptcies or reduced spending could all negatively affect our financial condition and results of operations.

These and other impacts of COVID-19 or other global or regional health pandemics, epidemics or similar public health threats could also have the effect of heightening many of the other risks described in Part I, Item 1A, “Risk Factors,” of our 2019 Annual Report on Form 10-K and the other reports we file from time to time with the SEC. The ultimate impact of COVID-19 on our business cannot be predicted and will depend on factors beyond our knowledge or control, including the duration and severity of the outbreak and resulting economic downturn, actions taken to contain the outbreak and mitigate its public health effects, and the extent to which normal economic and operating conditions can resume and when they might do so. Any of these factors could have an adverse effect on our business, outlook, financial condition, and results of operations and cash flows, which could be significant.

ENVIRONMENTAL REGULATION COMPLIANCE RISK. NW Holdings and NW Natural are subject to environmental regulations for our ongoing businesses, compliance with which could adversely affect our operations or financial results.

NW Holdings and NW Natural are subject to laws, regulations and other legal requirements enacted or adopted by federal, state and local governmental authorities relating to protection of the environment, including those legal requirements that govern discharges of substances into the air and water, the management and disposal of hazardous substances and waste, groundwater quality and availability, plant and wildlife protection, and other aspects of environmental regulation. For example, our natural gas operations are subject to reporting requirements to the Environmental Protection Agency (EPA) and the Oregon Department of Environmental Quality (ODEQ) regarding greenhouse gas emissions. Additionally, on March 10, 2020, the governor of Oregon issued an executive order establishing greenhouse gas (GHG) emissions reduction goals of at least 45% below 1990 emission levels by 2035 and at least 80% below 1990 emission levels by 2050 and directing state agencies and commissions to facilitate such GHG emission goals. Although the order does not specifically direct actions of natural gas distribution businesses, the OPUC is directed to prioritize proceedings and activities that advance decarbonization in the utility sector, mitigate energy burden experienced by utility customers and ensure system reliability and resource adequacy. The executive order also directs other agencies to cap and reduce GHG emissions from transportation fuels and all other liquid and gaseous fuels, including natural gas, adopt building energy efficiency goals for new building construction, reduce methane gas emissions from landfills and food waste, and submit a proposal for adoption of state goals for carbon sequestration and storage by Oregon’s forest, wetlands and agricultural lands. At this time, we are unable to predict the impact, if any, of the executive order on NW Natural. As an executive order, any implementation is reliant on state agency rule-making. The scope and content of any state commission or agency rules, as well as the time to propose, adopt and implement any such rules, has not been determined. These and other current and future additional environmental regulations could result in increased compliance costs or additional operating restrictions, which may or may not be recoverable in customer rates or through insurance. If these costs are not recoverable, or if these regulations reduce the desirability or cost-competitiveness of natural gas, they could have an adverse effect on NW Holdings’ or NW Natural’s operations or financial condition.
