QUESTAR CORPORATION

QUESTAR GAS COMPANY

QUESTAR PIPELINE COMPANY

NOTES ACCOMPANYING THE FINANCIAL STATEMENTS

The Notes Accompanying the Financial Statements apply to Questar Corporation, Questar Gas Company and Questar Pipeline Company unless otherwise noted.

Note 1 - Nature of Business

Questar Corporation (Questar or the Company) is a Rockies-based integrated natural gas company with three complementary and wholly-owned lines of business:

- Questar Gas Company (Questar Gas) provides retail natural gas distribution in Utah, Wyoming and Idaho.

- Wexpro Company (Wexpro) develops and produces natural gas from cost-of-service reserves for Questar Gas.

- Questar Pipeline Company (Questar Pipeline) operates interstate natural gas pipelines and storage facilities in the western

United States and provides other energy services.

Questar is headquartered in Salt Lake City, Utah. Shares of Questar common stock trade on the New York Stock Exchange (NYSE:STR).

Note 2 - Basis of Presentation of Interim Financial Statements

The interim financial statements contain the accounts of Questar and its wholly-owned subsidiaries. The financial statements were prepared in accordance with U.S. generally accepted accounting principles (GAAP) and with the instructions for Quarterly Reports on Form 10-Q and SEC Regulations S-X and S-K. All significant intercompany accounts and transactions have been eliminated in consolidation.

The financial statements reflect all normal, recurring adjustments and accruals that are, in the opinion of management, necessary for a fair presentation of financial position and results of operations for the interim periods presented. Interim financial statements do not include all of the information and notes required by GAAP for audited annual financial statements. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011.

The preparation of financial statements and notes in conformity with GAAP requires that management make estimates and assumptions that affect the amounts of revenues, expenses, assets and liabilities, and disclosure of contingent assets and liabilities. Actual results could differ from estimates. The results of operations for the three, nine and 12 months ended September 30, 2012, are not necessarily indicative of the results that may be expected for the year ending December 31, 2012.

Questar uses the equity method to account for its investment in an unconsolidated affiliate where it does not have control, but has significant influence. White River Hub, LLC is a limited liability company and FERC-regulated transporter of natural gas. Questar Pipeline owns 50% of White River Hub, LLC and is the operator. Generally, the investment in White River Hub, LLC on the Company's balance sheets equals the Company's proportionate share of equity reported by White River Hub, LLC. The investment is assessed for possible impairment when events indicate that the fair value of the investment may be below the Company's carrying value. When such a condition is deemed to be other than temporary, the carrying value of the investment is written down to its fair value, and the amount of the write-down is included in the determination of net income.

Note 3 - Comprehensive Income

Beginning in 2012, the Company and its subsidiaries adopted accounting guidance issued in June 2011 that resulted in the addition of statements of comprehensive income to the primary financial statements.

Comprehensive income attributable to Questar, as reported in Questar's Condensed Consolidated Statements of Comprehensive Income, is the sum of net income as reported in the Questar Consolidated Statements of Income and other comprehensive income (loss) (OCI). OCI includes recognition of the under-funded position of pension and other postretirement benefit plans, interest rate cash flow hedges, changes in the fair value of long-term investment and income taxes. These transactions are not the culmination of the earnings process but result from periodically adjusting historical balances to fair value. Income or loss is recognized when the pension or other postretirement benefit costs are accrued, as the Company records interest expense for hedged interest payments and when the long-term investment is sold or otherwise realized. The components of consolidated



Questar 2012 Form 10-Q	14

accumulated other comprehensive income (loss) (AOCI), net of income taxes, as reported in Questar's Condensed Consolidated Balance Sheets, are shown below:

Pension and other postretirement benefits	$	(202.8	)	$	(104.1	)	$	(202.8	)

Long-term investment	0.1			0.1			0.1
Accumulated other comprehensive (loss)	$	(225.9	)	$	(126.8	)	$	(226.1	)

Comprehensive income (loss), as reported in Questar Pipeline's Condensed Consolidated Statements of Comprehensive Income, is the sum of net income as reported in the Questar Pipeline Consolidated Statements of Income and OCI. OCI includes interest rate cash flow hedges and income taxes. These transactions are not the culmination of the earnings process but result from periodically adjusting historical balances to fair value. Income or loss is recognized as the company records interest expense for hedged interest payments. The component of consolidated AOCI, net of income taxes, as reported in Questar Pipeline's Condensed Consolidated Balance Sheets, is shown below:

Accumulated other comprehensive (loss)	$	(23.2	)	$	(22.8	)	$	(23.4	)

Note 4 - Earnings Per Share

Basic earnings per share (EPS) is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. Diluted EPS includes the potential increase in the number of outstanding shares that could result from the exercise of in-the-money stock options and the distribution of restricted stock units and performance shares that are part of the Company's Long-Term Stock Incentive Plan (LTSIP), less shares repurchased under the treasury stock method. Restricted stock and vested restricted stock units are participating securities for the computation of earnings per share. The application of the two-class method had an insignificant impact on the calculation of both basic and diluted EPS. A reconciliation of the components of basic and diluted shares used in the EPS calculation follows:



	3 Months Ended		9 Months Ended		12 Months Ended
	September 30,		September 30,		September 30,
	2012	2011	2012	2011	2012	2011
	(in millions)
Weighted-average basic common shares outstanding	175.4	177.5	177.0	177.3	177.2	177.1
Potential number of shares issuable under the Company's LTSIP	1.1	1.4	1.1	1.4	1.1	1.7
Weighted-average diluted common shares outstanding	176.5	178.9	178.1	178.7	178.3	178.8

Note 5 - Asset Retirement Obligations

Questar records an asset retirement obligation (ARO) when there is a legal obligation associated with the retirement of a tangible long-lived asset. At Questar, AROs apply primarily to abandonment costs associated with gas and oil wells, production facilities and certain other properties. The Company has not capitalized future abandonment costs on a majority of its long-lived transportation and distribution assets because the Company does not have a legal obligation to restore the area surrounding abandoned assets. The fair value of retirement costs is estimated by Company personnel based on abandonment costs of similar properties available to field operations and depreciated over the life of the related assets. Revisions to estimates result from material changes in the expected timing or amount of cash flows associated with AROs. Income or expense resulting from the settlement of ARO liabilities is included in net gain (loss) from asset sales in the Consolidated Statements of Income. The ARO liability is adjusted to present value each period through an accretion calculation using a credit-adjusted risk-



Questar 2012 Form 10-Q	15

free interest rate. Changes in Questar's AROs from the Consolidated Balance Sheets were as follows:



	9 Months Ended
	September 30,
	2012			2011
	(in millions)
AROs at beginning of year	$	63.8		$	60.9
Accretion	2.3			2.3
Liabilities incurred	2.2			0.9
Revisions in estimated cash flows	(1.2		)	2.4
Liabilities settled	(0.8		)	(2.0		)
AROs at September 30,	$	66.3		$	64.5

Wexpro collects from Questar Gas and deposits in trust certain funds related to AROs. The funds are recorded as other noncurrent assets and used to satisfy retirement obligations as the properties are abandoned. The accounting treatment of reclamation activities associated with AROs for properties administered under the Wexpro Agreement is defined in a guideline letter between Wexpro and the Utah Division of Public Utilities and the Staff of the Public Service Commission of Wyoming (PSCW).

Note 6 - Fair Value Measurements

Questar complies with the provisions of the accounting standards for fair value measurements and disclosures. The standards establish a fair value hierarchy. Level 1 inputs are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The Company had no assets or liabilities measured using Level 3 inputs at September 30, 2012, September 30, 2011 or December 31, 2011.

Beginning in 2012, Questar adopted fair value accounting guidance issued in May 2011. The guidance did not result in any changes to the reported amounts of assets or liabilities, but did result in disclosure of the fair value hierarchy levels associated with fair value estimates for financial assets and liabilities not carried at fair value.

Questar

The following table discloses the carrying amount, estimated fair value, and level within the fair value hierarchy of certain financial instruments not disclosed in other notes to Questar's financial statements in this Quarterly Report on Form 10-Q:

Questar 2012 Form 10-Q	16

approximate fair value. The long-term investment is recorded at fair value and consists of money market and short-term bond index mutual funds held in Wexpro's trust (see Note 5). The fair value of the long-term investment is based on quoted prices for the underlying funds. The fair value of fixed-rate long-term debt is based on the discounted present value of cash flows using the Company's current credit-risk adjusted borrowing rates.

The fair values of the Company's derivative instruments are the same as their carrying amounts, and are disclosed in Note 7. The fair values of derivative instruments, which consist entirely of spot and forward starting interest rate swaps, are estimated using a standard discounted cash flow model using observable market-based forward interest rates obtained from third-party financial institutions, and are considered Level 2 fair value measurements.

Questar Gas

The following table discloses the carrying amount, estimated fair value, and level within the fair value hierarchy of certain financial instruments not disclosed in other notes to Questar Gas's financial statements in this Quarterly Report on Form 10-Q:

The carrying amounts of cash and cash equivalents, notes receivable from Questar and notes payable to Questar approximate fair value. The fair value of fixed-rate long-term debt is based on the discounted present value of cash flows using Questar Pipeline's current credit-risk adjusted borrowing rates.



Questar 2012 Form 10-Q	17

The fair values of the company’s derivative instruments are the same as their carrying amounts, and are disclosed in Note 7. The fair values of derivative instruments, which consist entirely of forward starting interest rate swaps, are estimated using a standard discounted cash flow model using observable market-based forward interest rates obtained from third-party financial institutions, and are considered Level 2 fair value measurements.

Note 7 - Derivative Instruments and Hedging Activities

Questar and its subsidiaries may enter into derivative instruments to manage exposure to changes in current and future market interest rates. In order to mitigate its exposure to changes in the fair value of its fixed-rate corporate debt resulting from changes in benchmark interest rates, in the second quarter of 2011 Questar executed a fixed-to-floating interest rate swap transaction with a counterparty and converted $125.0 million of its 2.75% fixed rate long-term debt to floating rate debt. The 2.75% rate was swapped for a London Interbank Offered Rate (LIBOR)-based floating rate. Questar terminated and settled this hedge transaction in March 2012, for a deferred gain of $7.2 million, which is being amortized to interest expense through the maturity of the notes in 2016. Prior to its termination, this swap was accounted for as a fair value hedge under the accounting standards for derivatives and hedging.

Questar Pipeline entered into forward starting swaps totaling $150.0 million in the second and third quarters of 2011 in anticipation of issuing $180.0 million of notes in December 2011. Settlement of these swaps required payments of $37.3 million because of declines in interest rates. These swaps qualified as cash flow hedges and the settlement payments are being amortized to interest expense over the 30-year life of the debt.

All derivative instruments are required to be recorded on the balance sheet as either assets or liabilities measured at fair value. The designation of a derivative instrument as a hedge and its ability to meet hedge accounting criteria determines how the changes in fair value of the derivative instrument are reflected in the consolidated financial statements. A derivative instrument qualifies for fair value hedge accounting if, at inception and throughout its life, the derivative is expected to be highly effective in offsetting the changes in fair value of the hedged debt attributable to the hedged interest rate. Changes in the fair value of a derivative instrument qualifying and designated as a fair value hedge as well as the offsetting changes in the fair value of the hedged debt attributable to the hedged interest rate are recorded currently in the Consolidated Statements of Income. A derivative instrument qualifies for cash flow hedge accounting if, at inception and throughout its life, the derivative is expected to be highly effective in offsetting the changes in expected cash flows of the hedged interest payments. Changes in the effective portion of the fair value of a derivative instrument qualifying and designated as a cash flow hedge are initially recorded as a component of OCI in the period and remain in AOCI on the Consolidated Balance Sheets until they are reclassified into earnings as the Company records interest expense for the hedged interest payments. Ineffective portions of a qualifying and designated cash flow hedge are recorded immediately in earnings. Questar reports derivative instruments on the Consolidated Balance Sheets at their fair values on a gross basis and derivative positions with the same counterparty are not netted.

Interest rate swaps and forward starting interest rate swaps are settled in cash on periodic payment dates with one party paying the other for the net difference between the fixed and floating interest rate for the payment period as specified in the swap agreement, multiplied by the notional amount. Forward starting interest rate swaps used as cash flow hedges of forecasted fixed-rate debt issuances are terminated and settled in cash when the forecasted debt is issued or as the swaps expire, with one party paying the other for the swap's net fair value at the time of settlement. Questar reports cash flows related to derivative instruments qualifying and designated as hedges in the Consolidated Statements of Cash Flows based upon the nature of the hedged items.

The following table presents the pre-tax effects of the derivative instruments designated as a fair value hedge (including the hedged item) and cash flow hedges on the Consolidated Statements of Income as well as the pre-tax effects of the derivative instruments designated as cash flow hedges on OCI:

There was no ineffectiveness recognized on the fair value hedge for the three, nine and 12 months ended September 30, 2012 and 2011. There was no ineffectiveness recognized on the cash flow hedges for the three and nine months ended September 30, 2012. Ineffectiveness recognized on the cash flow hedges was de minimis in the 12 months ended September 30, 2012 and the three, nine and 12 months ended September 30, 2011. Reclassifications into earnings of amounts reported in AOCI will continue as interest expense is recorded for the hedged interest payments through maturity in 2041. Pre-tax net losses of $0.4 million are expected to be reclassified from AOCI to the Consolidated Statements of Income in the next 12 months. As of September 30, 2012, the Company is not hedging any exposure to variability in future cash flows of forecasted transactions.

The following table discloses the Level 2 fair values of the asset and liability derivative instruments designated as hedges in the Condensed Consolidated Balance Sheets:

Note 8 - Share-Based Compensation

Questar may issue stock options, restricted shares, restricted stock units and performance shares to certain officers, employees and non-employee directors under its LTSIP. Questar recognizes expense over time as the stock options, restricted shares, restricted stock units and performance shares vest. Total share-based compensation expense amounted to $7.5 million for the first nine months of 2012 compared to $8.0 million in 2011. Deferred share-based compensation, representing the unvested value of restricted share awards and restricted stock unit awards, amounted to $4.3 million at September 30, 2012. Deferred share-based compensation is included in common stock on the Condensed Consolidated Balance Sheets. For the first nine months, cash flow from income tax benefits in excess of recognized compensation expense amounted to $8.1 million in 2012



Questar 2012 Form 10-Q	19

compared to $5.3 million in 2011. There were 6,750,294 shares available for future grants at September 30, 2012.

Unvested stock options decreased by 88,396 shares to 29,398 shares in the first nine months of 2012. Questar did not grant any stock options in the first nine months of 2012. Stock-option transactions under the terms of the LTSIP are summarized below:

Restricted stock unit grants typically vest in equal installments over a three-year period from the grant date. At September 30, 2012, Questar's outstanding restricted stock units totaled 70,824 with a weighted-average price of $15.46 per share and a weighted-average remaining vesting period of nine months.

In the first quarter of 2012, Questar granted to certain Company executive officers a total of 136,846 performance shares under the terms of the LTSIP. The awards were designed to motivate and reward these executives for long-term Company performance and provide an incentive for them to remain with the Company. The target number of performance shares for each executive officer is subject to adjustment upward or downward based on the Company's performance over the three-year performance period ending December 31, 2014 with respect to specified performance criteria relative to a specified peer group of companies. The actual performance shares awarded, if any, will be distributed in the first quarter of 2015 so long as such executive officer was employed by the Company or its affiliates as of December 31, 2014. Half of any award will be distributed in shares of Company common stock and half in cash. The Monte Carlo simulation method was used to estimate the grant-date fair value of the performance share awards at $25.42 per share. Equity- and liability-based performance share compensation expense amounted to $1.4 million in the first nine months of 2012 and $0.6 million in the first nine months of 2011.

Note 10 - Employee Benefits

Questar has defined-benefit pension and life insurance plans covering a majority of its employees. On July 1, 2010, Questar closed its defined-benefit pension plan to new hires or rehires. The Company previously closed its postretirement medical coverage and life insurance plan to employees hired or rehired after January 1, 1997, and established maximum amounts paid by the Company.

Questar is subject to and complies with minimum-required and maximum-allowed annual contribution levels for its qualified pension plan as determined by the Employee Retirement Income Security Act and Internal Revenue Code. The 2012 estimated qualified pension expense is $34.6 million. The projected 2012 qualified pension plan funding is $78.6 million.

The Company also has a nonqualified pension plan for eligible employees who participate in the qualified pension plan, which provides a "make-up" benefit due to the limits on compensation that can be taken into account in determining benefits under the qualified pension plan. The nonqualified pension plan is unfunded; claims are paid from the Company's general funds. The 2012 nonqualified pension plan expense is estimated to be $3.9 million. Components of the qualified and nonqualified pension expense included in the determination of net income are listed in the table below:

Margin Analysis

Questar Gas margin (revenues minus gas costs) increased $0.1 million in the third quarter of 2012 compared to the third quarter of 2011, increased $5.2 million in the first nine months of 2012 compared to the first nine months of 2011 and increased $11.8



Questar 2012 Form 10-Q	24

million in the 12 months ended September 30, 2012 compared to the 12 months ended September 30, 2011. Following is a summary of major changes in Questar Gas margin:



	3 Months 2012 vs. 2011			9 Months 2012 vs. 2011			12 Months 2012 vs. 2011
	(in millions)
Customer growth	$	0.4		$	2.4		$	3.5

Demand-side management cost recovery	(0.6		)	1.9			4.4

Other	(0.5		)	(1.2		)	0.2
Increase	$	0.1		$	5.2		$	11.8

On September 30, 2012, Questar Gas served 925,386 customers, up 1.4% from 912,698 at September 30, 2011. Customer growth increased the margin by $0.4 million in the third quarter of 2012, $2.4 million in the first nine months of 2012 and $3.5 million in the 12 months ended September 30, 2012.

Questar Gas has benefited from a conservation-enabling (revenue decoupling) tariff since 2006. Under this tariff, Questar Gas is allowed to earn a margin for each general-service customer. Differences between the margin and the amount billed to customers are recovered from customers or refunded to customers through future rate changes. Because of this tariff, changes in usage per customer do not impact the company's margin. In addition, a weather-normalization adjustment of customer bills offsets the revenue impact of temperature variations.

A 2010 rate case stipulation approved an infrastructure cost-tracking mechanism that allows the company to place into rate base and earn on capital expenditures associated with a multi-year high-pressure natural gas feeder-line replacement program, and do it immediately upon the completion of each project. Questar Gas recognized $0.5 million of increased margin due to the infrastructure tracking mechanism in the third quarter of 2012, $3.5 million in the first nine months of 2012 and $5.7 million in the 12 months ended September 30, 2012.

Questar Gas margin increased during the nine- and 12-month periods ended September 30, 2012, due to higher recovery of demand-side management costs used to promote energy conservation by customers. Changes in the margin contribution from demand-side management recovery revenues are offset by equivalent changes in program expenses.

Expenses

Cost of natural gas sold decreased 14% in the third quarter of 2012, 21% in the first nine months of 2012 and 16% in the 12 months ended September 30, 2012, compared to the same periods of 2011 due to lower volumes and lower rates. Questar Gas accounts for purchased-gas costs in accordance with procedures authorized by the PSCU and the PSCW. Purchased-gas costs that are different from those provided for in present rates are accumulated and recovered or credited through future rate changes. As of September 30, 2012, Questar Gas had a $27.2 million under-collected balance in the purchased-gas adjustment account representing costs incurred in excess of costs recovered from customers. During the second quarter of 2012, Questar Gas credited $43.0 million of its over-collected balance to customers.

Operating and maintenance expenses increased $0.6 million in the third quarter of 2012, increased $4.6 million in the first nine months of 2012 and increased $10.5 million in the 12 months ended September 30, 2012, compared to the same periods of 2011. These increases included higher demand-side management costs of $1.9 million and $4.4 million for the nine- and 12-month periods, respectively. The demand-side management costs are for the company's energy efficiency program and are recovered from customers through periodic rate changes. General and administrative expenses increased $2.0 million in the 2012 third quarter, increased $1.6 million in the 2012 first nine months and increased $3.1 million in the 12 months ended September 30, 2012, compared to the prior year periods. The increases were due to higher employee and corporate allocated costs. Operating, maintenance, general and administrative expenses per customer, exclusive of demand-side management costs, were $145 in the 12 months ended September 30, 2012, compared to $137 in the 12 months ended September 30, 2011.

Other taxes were flat in the third quarter of 2012 compared to the third quarter of 2011. Other taxes increased 7% in the first nine months of 2012 and increased 5% in the 12 months ended September 30, 2012, compared to year-earlier periods due to increased property taxes.



Questar 2012 Form 10-Q	25

Depreciation and amortization expense increased 3% in the third quarter of 2012, increased 6% in the first nine months of 2012 and increased 7% in the 12 months ended September 30, 2012, compared to the 2011 periods. The higher depreciation was caused by plant additions driven by customer growth and feeder line replacements.

WEXPRO

Wexpro reported net income of $26.4 million in the third quarter of 2012 compared to $25.6 million in the third quarter of 2011, a 3% increase. Wexpro earned $76.5 million in the first nine months of 2012 compared to $71.6 million in the first nine months of 2011. Wexpro earned $100.1 million for the 12 months ending September 30, 2012 compared to $94.3 million for the year-earlier period. Following is a summary of Wexpro financial and operating results:

Revenues

Wexpro earned a 19.9% after-tax return on its average investment base for the 12 months ended September 30, 2012. Wexpro 2012 operating results benefited from a higher average investment base compared to the prior year period. Pursuant to the terms of a long-standing agreement referred to as the Wexpro Agreement, Wexpro recovers its costs and receives an after-tax return on its investment base. Wexpro's investment base includes its costs of commercial wells and related facilities adjusted for working capital and reduced for deferred income taxes and accumulated depreciation, depletion and amortization. The investment base grew in the 12 months ended September 30, 2012, but the increase due to investment in commercial wells was partially offset by increased deferred taxes due to bonus depreciation allowed for income tax purposes. Following is a summary

Wexpro produced 14.6 Bcf of cost-of-service natural gas for Questar Gas during the third quarter of 2012, up 16% from the third quarter of 2011. Wexpro produced 43.9 Bcf in the first nine months of 2012 compared to 37.1 Bcf in the first nine months of 2011. Wexpro produced 57.3 Bcf of cost-of-service gas in the 12 months ending September 30, 2012, compared to 49.8 Bcf in the 12 months ended September 30, 2011. On an annual basis, Wexpro natural gas production provides more than half of Questar Gas's supply requirements.

Revenues from oil and NGL sales increased 26% in the third quarter of 2012 over the third quarter of 2011, were up 21% in the first nine months of 2012 over the first nine months of 2011 and were up 22% in the 12 months ended September 30, 2012 over the year-earlier period. The increases were due to higher production volumes. The increase in revenues was partially offset by higher oil-related operating and maintenance expenses. Increased oil and NGL sales caused an increase in the sharing of oil income with Questar Gas customers under the terms of the Wexpro Agreement in the three, nine and 12 months ended September 30, 2012 compared to the three, nine and 12 months ended September 30, 2011.

Expenses

Operating and maintenance expenses were up 17% in the third quarter of 2012, up 23% in the first nine months of 2012 and up 19% in 12-month period ended September 30, 2012 compared to prior year periods due to higher production and increased spending on repairs and field costs. Lease operating expense per Mcfe was $0.42 in the first nine months of 2012 compared to $0.41 in the first nine months of 2011. General and administrative expenses were higher in the three-, nine- and 12-month periods ended September 30, 2012, compared to prior year periods. These increases are due to higher employee expenses. Production and other taxes were lower in the third quarter of 2012, lower in the first nine months of 2012 and lower in the 12 months ended September 30, 2012 compared to the prior-year periods due to changes in the value of natural gas, oil and NGL production.

Depreciation, depletion and amortization expense increased 24% in the third quarter of 2012, increased 23% in the first nine months of 2012 and increased 17% in the 12 months ended September 30, 2012, over the 2011 periods due to increased production volumes and investment in natural gas wells and facilities.

Revenues

As of September 30, 2012, Questar Pipeline had net firm-transportation contracts of 4,946 Mdth per day, including 1,020 Mdth per day from Questar Pipeline's 50% ownership of White River Hub, compared with 4,983 Mdth per day as of September 30, 2011. The increase in transportation revenues for the 12 months ended September 30, 2012, was due primarily to expansions of the Overthrust Pipeline system that were completed in March 2011. The decreases in transportation revenues in the third quarter and first nine months of 2012 were due to lower interruptible volumes and the expiration of firm contracts.

Questar Pipeline earns its largest transportation revenue from Questar Gas, with contracts for 881 Mdth per day. The primary Questar Gas transportation contract extends through mid 2017.



Questar 2012 Form 10-Q	28

Questar Pipeline owns and operates the Clay Basin underground storage complex in eastern Utah. This facility is 100% subscribed under long-term contracts. In addition to Clay Basin, Questar Pipeline owns and operates three smaller aquifer gas storage facilities. Questar Gas has contracted for 25% of firm-storage capacity at Clay Basin for terms extending from one to seven years and 100% of the firm-storage capacity at the aquifer facilities for terms extending for six years.

Questar Pipeline charges FERC-approved transportation and storage rates that are based on straight-fixed-variable rate design. Under this rate design, all fixed costs of providing service including depreciation and return on investment are recovered through the demand charge. About 95% of Questar Pipeline costs are fixed and recovered through these demand charges. Questar Pipeline's earnings are driven primarily by demand revenues from firm shippers. Since only about 5% of operating costs are recovered through volumetric charges, changes in transportation volumes do not have a significant impact on earnings.

NGL volumes increased 6% in the third quarter of 2012 compared to the third quarter of 2011, increased 3% in the first nine months of 2012 compared to the first nine months of 2011 and decreased 21% in the 12 months ended September 30, 2012, compared to the year-earlier period. NGL volumes declined on the Questar Pipeline transportation system due to upstream processing. NGL volumes increased at the Questar Field Services (a subsidiary of Questar Pipeline) plant in the third quarter of 2012 due to higher liquid content of processed gas. NGL prices were 24% lower in the third quarter of 2012, 16% lower in the first nine months of 2012 and 8% lower in the 12 months ended September 30, 2012, compared to year-earlier periods.

Expenses

Operating and maintenance expenses were relatively flat in the third quarter of 2012, decreased 6% in the first nine months of 2012 and decreased 16% in the 12 months ended September 30, 2012, compared to the corresponding 2011 periods. The decreased costs for the nine and 12 months ending September 30, 2012 are due primarily to lower regulatory sharing accruals, lower supplies and equipment expense and higher allocation of expense to capital projects. General and administrative expenses increased 26% in the third quarter of 2012, increased 8% in the first nine months of 2012 and increased 13% in the 12 months ended September 30, 2012, compared to corresponding 2011 periods. The increases were due to higher employee costs and allocations of corporate costs. Operating, maintenance, general and administrative expenses per dth transported were $0.09 in the first nine months of 2012 compared to $0.11 in the first nine months of 2011 due to higher volumes transported.

Other taxes decreased 8% in the third quarter of 2012, decreased 9% in the first nine months of 2012 and decreased 6% in the 12 months ended September 30, 2012, compared to year-earlier periods. The decreases are primarily due to lower property taxes.

Depreciation and amortization expense was up 6% in the third quarter of 2012, 7% in the first nine months of 2012, and 8% in the 12 months ended September 30, 2012, compared to the 2011 periods because of system expansions placed into service.

Net gain from asset sales

In the third quarter of 2012, Questar Pipeline realized a $2.4 million gain on the sale of real estate.

Strategic review of non-core assets

In October 2012, Questar Pipeline announced that it had begun a strategic review of non-core Questar Pipeline assets. This review will focus on Overthrust and Southern Trails pipelines. All strategic options will be analyzed, including joint ventures, asset sales or other alternatives.

Other Consolidated Results

Consolidated cost of sales

Questar Gas’s cost of natural gas sold includes amounts paid to Wexpro for cost-of-service gas supplies and amounts paid to Questar Pipeline for transportation and storage services. These intercompany transactions are eliminated in the consolidated Questar financial statements. Questar Gas records injection of natural gas into underground storage as a reduction of cost of natural gas sold. During the third quarters of both 2012 and 2011, the Questar consolidated income statements show a credit balance for cost of sales because of low sales volumes, the elimination of intercompany revenues and expenses, and the injection of natural gas into storage.

Interest expense

Consolidated interest expense was 9% higher in the third quarter of 2012, essentially flat in the first nine months of 2012 and 3% lower in the 12 months ending September 30, 2012, compared to the prior year periods. In December 2010, Questar issued $250.0 million of 2.75% Senior Notes due in 2016. In the second quarter of 2011, Questar executed a fixed-to-floating interest



Questar 2012 Form 10-Q	29

rate swap transaction to convert $125.0 million of its 2.75% Senior Notes to floating rate debt. Questar settled this hedge transaction in March 2012, for a deferred gain of $7.2 million, which is being amortized to interest expense over the remaining debt term.

Income taxes

Questar's effective combined federal and state income tax rate was 35.9% in the first nine months of 2012 and 35.8% in the first nine months of 2011.

Retirement incentive

Questar is looking at ways to reduce its overall cost structure. In October 2012, Questar announced a retirement incentive program for eligible employees. This program would provide an incentive payment equal to six months of base salary for those who are eligible and elect to retire by March 1, 2013. The cost of this program will be recognized in the fourth quarter of 2012.

LIQUIDITY AND CAPITAL RESOURCES

Operating Activities

Net cash provided by operating activities decreased 13% in the first nine months of 2012 compared to the first nine months of 2011 due primarily to changes in operating assets and liabilities, including a refund to customers of a credit balance in the purchased-gas adjustment account. Depreciation increased due to investment in plant and equipment and higher natural gas production. Deferred income taxes include the impact of bonus tax depreciation rules, which allow the Company to deduct 50% of the cost of certain capital expenditures for income tax purposes. Net cash provided by operating activities is presented below:

Investing Activities

A comparison of capital expenditures for the first nine months of 2012 and 2011 and a forecast for calendar year 2012 are presented below:



	9 Months Ended Sept. 30,				Forecast 12 Months Ended December 31,

Questar Pipeline	41.6		83.6		55
Corporate and other	3.5		1.4		10
Total capital expenditures	$	276.1	$	255.2	$	350

Questar Gas expects to invest about $55 million in its feeder line replacement program as well as provide service to approximately 12,000 new customers during 2012. Wexpro is continuing its planned low-risk and low-cost-structure development drilling program in the Vermillion area. Wexpro is also continuing to participate in wells drilled in the Pinedale area. Questar Pipeline's 2012 capital expenditure plans include transmission-system expansions and pipeline replacements.

Financing Activities

In the first nine months of 2012, the Company increased short-term debt by $44.0 million in part to fund a common share-



Questar 2012 Form 10-Q	30

repurchase program.

Questar issues commercial paper to meet short-term financing requirements. The commercial-paper program is supported by a revolving credit arrangement with various banks that provides back-up credit liquidity. Credit commitments under the revolving credit arrangement totaled $500.0 million at September 30, 2012, with no amounts borrowed. Commercial paper outstanding amounted to $263.0 million at September 30, 2012, compared with $278.0 million a year earlier. The Company believes the credit commitments are adequate for its working capital and short-term financing requirements during 2012.

Questar Pipeline repaid $180.0 million of medium-term notes in the second and third quarters of 2011. In December 2011 Questar Pipeline issued $180.0 million of notes due December 2041 with a 4.875% coupon rate. Questar Pipeline entered into forward starting swaps totaling $150.0 million in the second and third quarters of 2011 in anticipation of refinancing this debt. Settlement of these swaps required payments of $37.3 million because of declines in interest rates. These swaps qualified as cash flow hedges and the settlement payments are being amortized to interest expense over the 30-year life of the debt. The effective interest rate on the $180.0 million debt was 6.66% after adjusting for swap settlements and issuance costs.

Questar Gas has entered into a commitment to borrow $150 million of long-term debt in the private placement market on or before December 14, 2012. Questar Gas will issue $40 million of 12-year notes with an interest rate of 2.98% and $110 million of 15-year notes with an interest rate of 3.28%. Proceeds from the debt issue will be used primarily to repay $133.5 million of long-term debt that has matured or will mature as follows: $25.0 million which matured in August 2012; $66.5 million which matured in October 2012; $40.0 million which will mature in January 2013; and $2.0 million which will mature in September 2013. Additional proceeds will be used for other corporate purposes. The Company believes it will have adequate access to long-term capital based on current credit markets and its investment-grade credit ratings.

In March 2012, Questar occupied a new headquarters building and recorded a capital lease obligation for this building of $40.8 million, which is being amortized as lease payments are made over the 17-year lease term.

During the first nine months of 2012, Questar repurchased 3.6 million shares of its common stock in the market at a cost of $71.6 million. These repurchases were under a $100 million program approved by the Board of Directors to reduce the share count approximately to its June 30, 2010 level. Questar expects to continue to repurchase shares during the remainder of 2012.

At September 30, 2012, combined short-term debt, long-term debt and capital lease obligation was 57% and equity was 43% of total capital. The Company does not expect the ratio of debt in the capital structure to materially change over the next several years, except for seasonal variation in short-term debt for working capital requirements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Questar Gas's primary market risk exposures arise from changes in demand for natural gas and competition from other energy sources. The demand for natural gas will vary based on economic conditions, conservation efforts and prices. The temperature-adjusted usage per residential customer has historically decreased due to more energy efficient appliances and homes, and behavior changes in response to higher natural gas prices. The economic impact of this decline in usage per customer for residential customers has been offset by the addition of new customers and the conservation-enabling tariff.

Wexpro operations are subject to various government controls and regulation at the federal, state and local levels. Wexpro must obtain permits to drill and produce, maintain bonding requirements to drill and operate wells, submit and implement spill-prevention plans, and file notices relating to the presence, use, and release of specified contaminants incidental to gas and oil production. Wexpro is also subject to various conservation matters, including the regulation of the size of drilling and spacing units, the number of wells that may be drilled in a unit and the unitization or pooling of gas and oil properties. In addition, the Utah Division of Public Utilities and the PSCW are entitled to monitor the performance of the Company and Wexpro under the Wexpro Agreement and have retained two monitors, an independent certified public accountant and an independent hydrocarbon industry consulting firm, to review performance of the Agreement.

Questar Pipeline's primary market risk exposures arise from changes in demand for transportation and storage services and competition from other pipelines. The demand for transportation and storage services will vary based on the market's expectations about future volumes of natural gas likely to be produced in the basins served by Questar Pipeline and changes in market demand for natural gas. On some portions of its pipeline systems, the company faces the risk that it will not be successful in recontracting capacity under favorable terms once existing contracts expire. Questar Southern Trails Pipeline recontracted half of its capacity in the third quarter of 2012 at a market rate significantly lower than the previous rate, reducing revenues on this pipeline. Questar Southern Trails Pipeline is reviewing other strategic options for this pipeline because of the changing market for natural gas transportation to California. The Company continues to believe that at this time no impairment



Questar 2012 Form 10-Q	31

of the pipeline is necessary and will continue to assess the need for impairment as these options are evaluated.

Credit Risk

Questar Gas's primary market area is located in Utah, southwestern Wyoming and southeastern Idaho. Exposure to credit risk may be affected by the concentration of customers in these regions due to changes in economic or other conditions. Customers include individuals and numerous commercial and industrial enterprises that may react differently to changing conditions. Management believes that its credit-review procedures, loss reserves, customer deposits and collection procedures have adequately provided for usual and customary credit-related losses.

Questar Pipeline requests credit support, such as letters of credit and cash deposits, from companies that pose unfavorable credit risks. All companies posing such concerns were current on their accounts at September 30, 2012. Questar Pipeline's largest customers include Questar Gas, Rockies Express Pipeline, Wyoming Interstate Pipeline, EOG Resources, EnCana Marketing, PacifiCorp, Cross Timbers Energy Services and Anadarko Energy Services Company.

Interest-Rate Risk Management

On September 30, 2012, Questar had $1,057.9 million of fixed-rate long-term debt with a fair value of $1,237.5 million and a weighted-average life to maturity of 10.3 years. Questar also had $263.0 million of floating-rate debt outstanding in the form of short-maturity commercial paper at September 30, 2012.

In December 2010, Questar issued $250.0 million of 2.75% Senior Notes due in 2016 to repay commercial paper. In the second quarter of 2011, Questar executed a fixed-to-floating interest rate swap transaction to convert $125.0 million of its 2.75% Senior Notes to floating rate debt. Questar settled this hedge transaction in March 2012, for a deferred gain of $7.2 million, which is being amortized to interest expense over the remaining debt term.

Based on such evaluation, such officers have concluded that, as of September 30, 2012, Questar's, Questar Gas's and Questar Pipeline's disclosure controls and procedures are effective.

Changes in Internal Controls.

There were no changes in Questar's, Questar Gas's and Questar Pipeline's internal controls over financial reporting that occurred during the quarter ended September 30, 2012, that have materially affected, or are reasonably likely to materially affect, Questar's, Questar Gas's and Questar Pipeline's internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

On May 1, 2012, Questar Gas Company filed a legal action against QEP Field Services Company, a subsidiary of QEP Resources, Inc. The case, entitled Questar Gas Company v. QEP Field Services Company, was filed in the Third District Court in Salt Lake County, Utah. Questar Gas believes certain charges of QEP Field Services Company for gathering services exceed the amounts contemplated under a Gas Gathering Agreement, effective September 1, 1993, pertaining to certain gas produced by Wexpro Company under the Wexpro Agreement. Questar Gas is alleging breach of contract by QEP Field Services Company and is seeking an accounting, damages and a declaratory judgment relating to the services and charges under the Gas Gathering Agreement. The charges under the Gas Gathering Agreement are included in Questar Gas's rates as part of its purchased gas costs. Depending on the outcome of the litigation, Questar Gas may seek approval to pay a refund to its customers. While Questar Gas intends to vigorously pursue its legal rights, the claims involve complex legal issues and uncertainties that make it difficult to predict the outcome of the cases and therefore management cannot determine at this time whether this litigation may have an adverse material effect on its financial position, results of operations or cash flows.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.

Questar had no unregistered sales of equity securities during the third quarter of 2012. The following table sets forth the Company's purchases of common stock registered under section 12 of the Exchange Act that occurred during the quarter ended September 30, 2012:
