Note 1. Nature of Operations

Questar Gas is a wholly-owned subsidiary of Dominion Energy Questar which, effective September 2016, is a wholly-owned subsidiary of Dominion Energy.

Questar Gas distributes natural gas as a public utility in Utah, southwestern Wyoming and a small portion of southeastern Idaho. The Utah, Wyoming and Idaho Commissions have granted Questar Gas the necessary regulatory approvals to serve these areas. Questar Gas also has long-term franchises granted by communities and counties within its service area.

Revenue generated by Questar Gas is based primarily on rates established by the Utah and Wyoming Commissions. The Idaho Commission has contracted with the Utah Commission for rate oversight of Questar Gas operations in Idaho.

Wexpro, an affiliate, provides the majority of Questar Gas' natural gas supply and Dominion Energy Questar Pipeline, an affiliate, provides the majority of Questar Gas' transportation and storage services.

Note 2. Significant Accounting Policies

As permitted by the rules and regulations of the SEC, Questar Gas' accompanying unaudited Financial Statements contain certain condensed financial information and exclude certain footnote disclosures normally included in annual audited financial statements prepared in accordance with GAAP. These unaudited Financial Statements should be read in conjunction with the Financial Statements and Notes in Questar Gas' Annual Report on Form 10-K for the year ended December 31, 2016.

In the opinion of management, the accompanying unaudited Financial Statements contain all adjustments necessary to present fairly its financial position as of June 30, 2017, its results of operations for the three and six months ended June 30, 2017 and 2016 and its cash flows for the six months ended June 30, 2017 and 2016. Such adjustments are normal and recurring in nature unless otherwise noted.

Questar Gas makes certain estimates and assumptions in preparing its Financial Statements in accordance with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses and cash flows for the periods presented. Actual results may differ from those estimates.

The results of operations for interim periods are not necessarily indicative of the results expected for the full year. Information for quarterly periods is affected by seasonal variations in sales, rate changes, purchased gas expenses and other factors.

Questar Gas reports certain contracts and instruments at fair value. See Note 4 for further information on fair value measurements.

Certain amounts in the 2016 Financial Statements and Notes have been reclassified to conform to the 2017 presentation for comparative purposes. The reclassifications did not affect Questar Gas' net income, total assets, liabilities, equity or cash flows.

Note 4. Fair Value Measurements

Questar Gas' fair value measurements are made in accordance with the policies discussed in Note 5 to the Financial Statements in Questar Gas' Annual Report on Form 10-K for the year ended December 31, 2016. See Note 5 in this report for further information about Questar Gas' derivatives and hedge accounting activities.

Questar Gas enters into certain physical forwards and options, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical forward contracts. An option model is used to value Level 3 physical options. The discounted cash flow model for forwards calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return, and credit spreads. The option model calculates mark-to-market valuations using variations of the Black-Scholes option model. The inputs into the models are the forward market prices, implied price volatilities, risk-free rate of return, the option expiration dates, the option strike prices, the original sales prices, and volumes. For Level 3 fair value measurements, forward market prices and implied price volatilities are considered unobservable. The unobservable inputs are developed and substantiated using historical information, available market data, third-party data, and statistical analysis. Periodically, inputs to valuation models are reviewed and revised as needed, based on historical information, updated market data, market liquidity and relationships, and changes in third-party pricing sources.

The following table presents Questar Gas' quantitative information about Level 3 fair value measurements at June 30, 2017.  The range and weighted average are presented in dollars for market price inputs and percentages for price volatility.

Sensitivity of the fair value measurements to changes in the significant unobservable inputs is as follows:

Fair Value of Financial Instruments

Substantially all of Questar Gas' financial instruments are recorded at fair value, with the exception of the instruments described below, which are reported at historical cost.
