We generally are not a taxable entity for federal or state and local income tax purposes. The tax on net income is generally borne by our parent, Williams. Net income for financial statement purposes may differ significantly from taxable income of Williams as a result of differences between the tax basis and financial reporting basis of assets and liabilities.
Accounting Standards Issued and Adopted
In FebruaryJune 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02 “Leases (Topic 842)” (ASU 2016-02). ASU 2016-02 establishes a comprehensive new lease accounting model. ASU 2016-02 modifies the definition of a lease, requires a dual approach to lease classification similar to prior lease accounting, and causes lessees to recognize operating leases on the balance sheet as a lease liability measured as the present value of the future lease payments with a corresponding right-of-use asset, with an exception for leases with a term of one year or less. Additional disclosures are required regarding the amount, timing, and uncertainty of cash flows arising from leases. In January 2018, the FASB issued ASU 2018-01 “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” (ASU 2018-01). Per ASU 2018-01, land easements and rights-of-way are required to be assessed under ASU 2016-02 to determine whether the arrangements are or contain a lease. ASU 2018-01 permits an entity to elect a transition practical expedient to not apply ASU 2016-02 to land easements that exist or expired before the effective date of ASU 2016-02 and that were not previously assessed under the previous lease guidance in Accounting Standards Codification (ASC) Topic 840 “Leases.”
In July 2018, the FASB issued ASU 2018-11 “Leases (Topic 842): Targeted Improvements” (ASU 2018-11). Prior to ASU 2018-11, a modified retrospective transition was required for financing or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows entities an additional transition method to the existing requirements whereby an entity could adopt the provisions of ASU 2016-02 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption. ASU 2018-11 also allows a practical expedient that permits lessors to not separate non-lease components from the associated lease component if certain conditions are present. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018. We prospectively adopted ASU 2016-02 effective January 1, 2019, and did not adjust prior periods as permitted by ASU 2018-11 (See Note 3).
We completed our review of contracts to identify leases based on the modified definition of a lease and implemented changes to our internal controls to support management in the accounting for and disclosure of leasing activities upon adoption of ASU 2016-02. We implemented a financial lease accounting system to assist management in the accounting for leases upon adoption. The most significant changes to our financial statements as a result of adopting ASU 2016-02 relate to the recognition of a $17.8


million lease liability and offsetting right-of-use asset in our Balance Sheetfor operating leases. We also evaluated ASU 2016-02’s available practical expedients on adoption. We generally elected to adopt the practical expedients, which includes the practical expedient to not separate lease and non-lease components by both lessees and lessors by class of underlying assets and the land easements practical expedient.
Accounting Standards Issued But Not Yet Adopted
In June 2016, the FASB issued ASU 2016-13 “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). ASU 2016-13 changeschanged the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans, and other instruments, entities will beare required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowances for losses. The guidance also requires increased disclosures.We adopted ASU 2016-13 is effective for interim and annual periods beginning after December 15, 2019. We plan to adopt as of January 1, 2020. We anticipate that ASU 2016-13 will2020, which primarily applyapplied to our short-term trade receivables. WhileThere was no cumulative effect adjustment to retained earnings upon adoption.
The majority of our trade receivable balances are due within 30 days. We monitor the credit quality of our counterparties through review of collection trends, credit ratings, and other analysis, such as bankruptcy monitoring. Financial assets are evaluated as one pool. Changes in counterparty risk factors could lead to reassessment of the composition of our financial assets as one pool. We calculate our allowance for credit losses incorporating an aging method. In estimating our expected credit losses, we utilized historical loss rates over many years. Our expected credit loss estimate considered both internal and external forward-looking commodity price expectations, as well as counterparty credit ratings, and factors impacting their near-term liquidity.
Past due accounts are generally written off against the allowance for doubtful accounts only after all collection attempts have been exhausted. We do not expecthave a significant financial impact, we are currently developing additional processes, procedures and internal controls in order to make the necessary credit loss assessments and required disclosures.material amount of significantly aged receivables at June 30, 2020.

3. LEASES
We are a lessee through noncancellable lease agreements for property and equipment consisting primarily of buildings, land, vehicles, and equipment used in both our operations and administrative functions. We recognize a lease liability with an offsetting right-of-use asset in our Balance Sheet for operating leases based on the present value of the future lease payments. As an accounting policy, we have elected to combine lease and non-lease components for all classes of leased assets in our calculation of the lease liability and the offsetting right-of-use asset.
Our lease agreements require both fixed and variable periodic payments, with initial terms typically ranging from one year to 15 years, with some having a term of up to 38 years. Payment provisions in certain of our lease agreements contain escalation factors which may be based on stated rates or a change in a published index at a future time. The amount by which a lease escalates based on the change in a published index, which is not known at lease commencement, is considered a variable payment and is not included in the present value of the future lease payments, which only includes those that are stated or can be calculated based on the lease agreement at lease commencement. In addition to the noncancellable periods, many of our lease agreements provide for one or more extensions of the lease agreement for periods ranging from one year in length to an indefinite number of times following the specified contract term. Other lease agreements provide for extension terms that allow us to utilize the identified leased asset for an indefinite period of time so long as the asset continues to be utilized in our operations. In consideration of these renewal features, we assess the term of the lease agreements, which includes using judgment in the determination of which renewal periods and termination provisions, when at our sole election, will be reasonably certain of being exercised. Periods after the initial term or extension terms that allow for either party to the lease to cancel the lease are not considered in the assessment of the lease term. Additionally, we have elected to exclude leases with an original term of one year or less, including renewal periods, from the calculation of the lease liability and the offsetting right-of-use asset.
We used judgment in determining the discount rate upon which the present value of the future lease payments is determined. This rate is based on a collateralized interest rate corresponding to the term of the lease agreement using company, industry, and market information available.

4.3. RATE AND REGULATORY MATTERS
FERC Developments
Notice of Inquiry (Docket No. PL19-4-000) On MarchMay 21, 2019,2020, the FERC issued a Notice of Inquiry (NOI)“Policy Statement on Determining Return on Equity for Natural Gas and Oil Pipelines” (Policy Statement) in Docket No. PL19-4-000 seeking comments regarding whether and, if so, how FERC should reviseadopting changes to its policies for determiningconcerning the basecalculation of a public utility return on equity (ROE) used in setting rates charged by jurisdictional public utilities.. In this Policy Statement, the FERC also seeks comment on, among other things, whether FERC should changerevised its ROE policies policy


for interstate natural gas pipelines and oil pipelines to align with its policy for electric public utilities. FERC’s action followsprovide that the FERC will determine a decision frompipeline’s ROE by averaging the United States Courtresults of Appeals for the District of Columbia Circuit, which vacated and remanded a series of earlier FERC orders establishing a new base ROE for certain electric transmission owners.  Following that decision, FERC proposed in the remanded proceedings that it rely on four financial models to establish ROEs for the affected utilities rather than rely primarily on its long-used, two-step Discounted Cash Flow model. Inmodel and the NOI,Capital Asset Pricing Model, with each weighted equally. The FERC posesdeclined to adopt any additional policy changes at this time and will address all other issues concerning the determination of a series of questions and invited comments on this proposed new approach, including whether it should apply the new approach topipeline’s ROE as they arise in future proceedings involving interstate natural gas and oil pipeline ROEs. We currently are monitoring this proceeding. proceedings.
Our next general rate case must be filed for new rates to become effective no later than January 1, 2023.



5.4. CONTINGENT LIABILITIES AND COMMITMENTS
Environmental Matters
We are subject to the National Environmental Policy Act and other federal and state legislation regulating the environmental aspects of our business. Except as discussed below, our management believes that we are in substantial compliance with existing environmental requirements. Environmental expenditures are expensed or capitalized depending on their future economic benefit and potential for rate recovery. We believe that, with respect to any expenditures required to meet applicable standards and regulations, the FERC would grant the requisite rate relief so that substantially all of such expenditures would be permitted to be recovered through rates.
Beginning in the mid-1980s, we evaluated many of our facilities for the presence of toxic and hazardous substances to determine to what extent, if any, remediation might be necessary. We identified polychlorinated biphenyl (PCB) contamination in air compressor systems, soils, and related properties at certain compressor station sites. Similarly, we identified hydrocarbon impacts at these facilities due to the former use of earthen pits, lubricating oil leaks or spills, and excess pipe coating released to the environment. In addition, heavy metals have been identified at these sites due to the former use of mercury containing meters and paint and welding rods containing lead, cadmium, and arsenic. The PCBs were remediated pursuant to a Consent Decree with the U.S. Environmental Protection Agency (EPA) in the late 1980s, and we conducted a voluntary clean-up of the hydrocarbon and mercury impacts in the early 1990s. In 2005, the Washington Department of Ecology required us to re-evaluate our previous clean-ups in Washington. During 2006 to 2015, 129 meter stations were evaluated, of which 82 required remediation. As of June 30, 2019,2020, all of the meter stations have been remediated. During 2006 to 2018, 14 compressor stations were evaluated, of which 11 required remediation. As of June 30, 2019,2020, 10 compressor stations have been remediated. At June 30, 20192020, we had accrued liabilities totaling approximately $1.9$1.1 million, $1.6$0.1 million recorded in Accrued liabilities - Other and $0.3$1.0 million recorded in Other Noncurrent Liabilities - Other in the accompanying Balance Sheet. At December 31, 20182019, we had accrued liabilities totaling approximately $2.0$1.2 million, $1.3$0.1 million recorded in Accrued liabilities - Other and $0.7$1.1 million recorded in Other Noncurrent Liabilities - Other in the accompanying Balance Sheet. We are conducting environmental assessments and implementing a variety of remedial measures that may result in increases or decreases in the total estimated costs.
The EPA and various state regulatory agencies routinely promulgate and propose new rules, and issue updated guidance to existing rules. These rulemakings include, but are not limited to, rules for reciprocating internal combustion engine and combustion turbine maximum achievable control technology, air quality standards for one-hour nitrogen dioxide emissions, and volatile organic compound and methane new source performance standards impacting design and operation of storage vessels, pressure valves, and compressors. The EPA previously issued its rule regarding National Ambient Air Quality Standards for ground-level ozone. We are monitoring the rule’s implementation as it will trigger additional federal and state regulatory actions that may impact our operations. Implementation of the regulations is expected to result in impacts to our operations and increase the cost of additions to Property, plant, and equipment - net in the Balance Sheet for both new and existing facilities in affected areas. We are unable to reasonably estimate the cost of additions that may be required to meet the regulations at this time due to uncertainty created by various legal challenges to these regulations and the need for further specific regulatory guidance.
Other Matters
Various other proceedings are pending against us and are considered incidental to our operations.
Summary
We estimate that for all matters for which we are able to reasonably estimate a range of loss, including those noted above and others that are not individually significant, our aggregate reasonably possible losses beyond amounts accrued for all of our contingent liabilities are immaterial to our expected future annual results of operations, liquidity and financial position. These calculations have been made without consideration of any potential recovery from third-parties. We have disclosed all significant matters for which we are unable to reasonably estimate a range of possible loss.


6.5. DEBT AND FINANCING ARRANGEMENTARRANGEMENTS
Credit Facility
We, along with Williams and Transcontinental Gas Pipe Line Company, LLC (Transco) (the “borrowers”), are party to a Credit Agreement with aggregate commitments available of $4.5 billion, with up to an additional $500 million increase in aggregate commitments available under certain circumstances. We and Transco are each subject to a $500 million borrowing sublimit. Letter of credit commitments of $1.0 billion are subject to the $500 million borrowing sublimit applicable to us and Transco, available to the borrowers.Transco. At June 30, 2019, no2020, 0 letters of credit have been issued and no0 loans were outstanding under the credit facility.


Williams participates in a commercial paper program, and Williams management considers amounts outstanding under this program to be a reduction of available capacity under the credit facility. The program allows a maximum outstanding amount at anytime of $4.0 billion of unsecured commercial paper notes. At June 30, 2019,2020, Williams had no0 outstanding commercial paper.
7.6. FINANCIAL INSTRUMENTS
Fair Value of Financial Instruments
The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:
Cash and advances to affiliate—The carrying amounts approximate fair value because of the short-term nature of these instruments.
Long-term debt—The disclosed fair value of our long-term debt, which we consider as a level 2 measurement, is determined by a market approach using broker quoted indicative period-end bond prices. The quoted prices are based on observable transactions in less active markets for our debt or similar instruments. The carrying amount and estimated fair value of our long-term debt including current maturities, were $576.6$577.5 million and $623.7$646.8 million, respectively, at June 30, 2019,2020, and $576.2$577.0 million and $577.1$637.8 million, respectively, at December 31, 20182019.

8.7. TRANSACTIONS WITH AFFILIATES
We are a participant in Williams’ cash management program, and we make advances to and receive advances from Williams. At June 30, 2020 and December 31, 2019, our advances to Williams totaled approximately $230.6$248.7 million and at December 31, 2018, our advances to Williams totaled approximately $180.4 million.$201.3 million, respectively. These advances are represented by demand notes and are classified as Receivables - Advances to affiliate in the accompanying Balance Sheet. The interest rate on these intercompany demand notes is based upon the daily overnight investment rate paid on Williams’ excess cash at the end of each month, which was 2.270.05 percent at June 30, 2019.2020. The interest income from these advances was $0.1 million and $0.6 million for the three and six months ended June 30, 2020, respectively, and $1.2 million and $2.2 million for the three and six months ended June 30, 2019, respectively, and $0.4 million and $0.9 million for the three and six months ended June 30, 2018, respectively. Such interest income is included in Other (Income) and Other Expenses – Miscellaneous other (income) expenses, net on the accompanying Statement of Net Income.
We have no0 employees. Services necessary to operate our business are provided to us by Williams and certain affiliates of Williams. We reimburse Williams and its affiliates for all direct and indirect expenses incurred or payments made (including salary, bonus, incentive compensation, and benefits) in connection with these services. Employees of Williams also provide general administrative and management services to us, and we are charged for certain administrative expenses incurred by Williams. These charges are either directly identifiable or allocated to our assets. Direct charges are for goods and services provided by Williams at our request. Allocated charges are based on a three-factor formula, which considers revenues; property, plant, and equipment; and payroll. In management’s estimation, the allocation methodologies used are reasonable and result in a reasonable allocation to us of our costs of doing business incurred by Williams. We were billed $26.8$23.1 million and $48.9$45.8 million in the three and six months ended June 30, 2019,2020, respectively, and $23.6$26.8 million and $45.7$48.9 million forin the three and six months ended June 30, 2018,2019, respectively, for these services. Such expenses are primarily included in General and administrative and Operation and maintenance expenses on the accompanying Statement of Net Income. The amount billed to us for the six months ended June 30, 2019, includes $3.2 million recognized in the second quarter for estimated severance and related costs driven by a voluntary separation program associated with a review of Williams' enterprise cost structure.
During the six months ended June 30, 20192020 and 2018,2019, we declared and paid cash distributions to our parent of $46.0$88.0 million and $87.0$46.0 million, respectively. During July 2019,2020, we declared and paid an additional cash distribution of $32.0$36.0 million to our parent.
We have entered into various other transactions with certain related parties, the amounts of which were not significant. These transactions and the above-described transactions are made on the basis of commercial relationships and prevailing market prices or general industry practices.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

GENERAL
The following discussion should be read in conjunction with the Management’s Discussion and Analysis, Financial Statements, and Notes contained in Items 7 and 8 of our 20182019 Annual Report on Form 10-K and with the Financial Statements and Notes contained in this Form 10-Q.
RESULTS OF OPERATIONS
Analysis of Financial Results
This analysis discusses financial results of our operations for the six-month periods ended June 30, 20192020 and 20182019. Variances due to changes in natural gas prices and transportation volumes have little impact on revenues, because under our rate design methodology, the majority of overall cost of service is recovered through firm capacity reservation charges in our transportation rates.
Our operating revenuesOperating Revenues increased $4.2$0.8 million, or 2less than 1 percent, in the first six months of 20192020 as compared with the first six months of 20182019 primarily due toto:
•$2.8 million higher natural gas storagetransportation revenues primarily as a result of $3.0 million ($1.4 millionplacing the North Seattle Upgrade into

•The increase in liquefaction, $1.1natural gas transportation revenues was partly offset by a $2.0 million increasedecrease in natural gas storage
resulting primarily from lower gas injections, a decrease in the use of Park and Loan services and $0.4 million increase in lower demand for

In the periods ended June 30, 2020 and 2019, and 2018, transportationTransportation services accounted for 9697 percent and gas storage services accounted for 43 percent of our operating revenues.revenues, and 96 percent and 4 percent, respectively.
Operating expenses increased $2.5Expenses decreased $0.4 million, or 2less than 1 percent, for the first six months of 20192020 as compared to the same period in 2018,2019, mostly due to $3.2to:

Other (income) and other expenses had an unfavorable change of $1.6 million primarily associated with a property tax adjustment and $1.5 million lower costs related to the expiration of certain levelized incremental evergreen contracts in 2018.
Interest expense decreased $1.0$1.9 million, or 717 percent, for the first six months of 2020 compared to 2019 due to lower allowances for funds used in construction and tax gross ups on prepayments as a result lower capitalized construction costs. In addition, higher interest was accrued as a result of the repaymentincreasing reserve for customer tax refunds as required by RP17-1136.
Recent Developments
COVID-19
The outbreak of novel coronavirus (COVID-19) has severely impacted global economic activity and caused significant volatility and negative pressure in financial markets. We are monitoring the COVID-19 pandemic and are taking steps intended to protect the safety of our 6.05 percent senior notes on June 15, 2018, partially offsetcustomers, employees and communities, and to support the continued delivery of safe and reliable service to our customers and the communities we serve. We are continuing to monitor developments with respect to the outbreak and note the following:
Our financial condition, results of operations, and liquidity have not been materially impacted by the interest on the additional $250 milliondirect effects of 4.0 percent senior unsecured notes issued on August 24, 2018.

COVID-19.

We believe we have the ability to access the debt market if necessary, and continue to have significant levels of unused capacity on our revolving credit facility with no significant debt maturities in the near future.
We have implemented remote working arrangements where possible and restricted business-related travel. Implementation of these measures has not required material expenditures or significantly impacted our ability to operate our business.
Our remote working arrangements have not significantly impacted our internal controls over financial reporting and disclosure controls and procedures.

Item 4. Controls and Procedures
Our management, including our Senior Vice President—WestPresident and our Vice President and Chief Accounting Officer, does not expect that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 as amended) (Disclosure Controls) or our internal control over financial reporting (Internal Controls) will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. We monitor our Disclosure Controls and Internal Controls and make modifications as necessary; our intent in this regard is that the Disclosure Controls and Internal Controls will be modified as systems change and conditions warrant.
Evaluation of Disclosure Controls and Procedures
An evaluation of the effectiveness of the design and operation of our Disclosure Controls was performed as of the end of the period covered by this report. This evaluation was performed under the supervision and with the participation of our management, including our Senior Vice President—WestPresident and our Vice President and Chief Accounting Officer. Based upon that evaluation, our Senior Vice President—WestPresident and our Vice President and Chief Accounting Officer concluded that these Disclosure Controls are effective at a reasonable assurance level.
Changes in Internal Control Over Financial Reporting
There have been no changes during the second quarter of 20192020 that have materially affected, or are reasonably likely to materially affect, our Internal Control over Financial Reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings
On August 27, 2018, Northwest Pipeline LLC received a Notice of Violation/Cease and Desist Order (NOV) from the Water Quality Control Division of the Colorado Department of Public Health & Environment (the Division) regarding certain alleged violations of the Colorado Water Quality and Control Act and its General Permit under the Colorado Discharge Permit System related to its stormwater management practices at two construction sites. On March 4, 2019, the Division provided Northwest with its initial penalty calculation, proposing a penalty of approximately $81,000 in settlement of all violations alleged in the NOV. Northwest continues to work with the Division to reach a final, settled resolution.
