NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
1. Financial Statement Presentation
During interim periods, Cabot Oil & Gas Corporation (the Company) follows the same accounting policies disclosed in its Annual Report on Form 10-K for the year ended December 31, 2016 (Form 10-K) filed with the Securities and Exchange Commission (SEC). The interim financial statements should be read in conjunction with the notes to the consolidated financial statements and information presented in the Form 10-K. In management’s opinion, the accompanying interim condensed consolidated financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary for a fair statement. The results for any interim period are not necessarily indicative of the expected results for the entire year.
Certain reclassifications have been made to prior year statements to conform with the current year presentation. These reclassifications had no impact on previously reported stockholders' equity, net income (loss) or cash flows, except as discussed in "Recently Adopted Accounting Pronouncements" below.
Recently Adopted Accounting Pronouncements
Stock-Based Compensation. In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09, Improvements to Employee Share-Based Payment Accounting, as an amendment to Accounting Standards Codification (ASC) Topic 718. The areas for simplification in this update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance is effective for interim and annual periods beginning after December 15, 2016. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures and intrinsic value should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term should be applied prospectively. An entity may elect to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method. The Company elected to apply this guidance on a prospective basis.
The Company adopted this guidance effective January 1, 2017. The recognition of previously unrecognized windfall tax benefits resulted in a cumulative-effect adjustment of $42.2 million, which increased retained earnings and decreased net deferred tax liabilities by the same amount as of the beginning of 2017. Effective January 1, 2017, cash paid by the Company when directly withholding shares from employee awards for tax-withholding purposes will be classified as a financing activity. This change has been recognized retrospectively beginning January 1, 2015. Prior periods have been adjusted as follows:

|  | Net Cash Provided by Operating Activities |  | Net Cash Provided by Financing Activities
(In thousands) |  | As Reported |  | As Adjusted |  | As Reported |  | As Adjusted
Year ended December 31, 2015 |  | $ | 740,737 |  |  | $ | 749,598 |  |  | $ | 232,157 |  |  | $ | 223,296 |
Three months ended March 31, 2016 |  | 62,090 |  |  | 67,112 |  |  | 570,773 |  |  | 565,751 |
Six months ended June 30, 2016 |  | 147,244 |  |  | 152,290 |  |  | 497,474 |  |  | 492,428 |
Nine months ended September 30, 2016 |  | 252,649 |  |  | 257,705 |  |  | 468,171 |  |  | 463,115 |
Year ended December 31, 2016 |  | 392,377 |  |  | 397,441 |  |  | 458,869 |  |  | 453,805 |

The remaining provisions of this amendment did not have a material effect on the Company's financial position, results of operations or cash flows.
Accounting Changes and Error Corrections. In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Venture (Topic 323), which states that registrants should consider additional qualitative disclosures if the impact of an issued but not yet adopted ASU is unknown or cannot be reasonably estimated and to include a description of the effect of the accounting policies that the registrant expects to apply, if determined. Transition guidance in certain issued but not yet adopted ASUs, including Leases and Revenue Recognition, was also updated to reflect this amendment. This guidance is effective immediately. The Company adopted this guidance during the first quarter of 2017. The adoption of this guidance impacted the Company's disclosures but had no effect on its financial position, results of operations or cash flows.

Table of Contents
Retirement Benefits. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715). The amendments in this update require that an employer report the service cost component of postretirement benefits in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable. The amendments in this update should be applied retrospectively for the presentation of the service cost component and the other components of net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic benefit cost in assets.
The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements have not been issued or made available for issuance. The Company elected to early adopt this guidance effective January 1, 2017. The reclassification of interest and amortization of prior service cost resulted in an increase in operating income and an increase in other expense (non-operating expense) of $1.6 million and $1.4 million for the years ended December 31, 2016 and 2015, respectively, and $1.2 million for the nine months ended September 30, 2016.
Recently Issued Accounting Pronouncements
Financial Instruments. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall, as an amendment to ASC Subtopic 825-10. The amendments in this update address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among other items, this update will simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. This impairment assessment reduces the complexity of the other-than-temporary impairment guidance that entities follow currently. The guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption of this amendment is not permitted. The Company is currently evaluating the effect that adopting this guidance will have on its financial position, results of operation or cash flows.
Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases, as a new Topic, ASC Topic 842. The new lease guidance supersedes Topic 840. The core principle of the guidance is that a company should recognize the assets and liabilities that arise from leases. This ASU does not apply to leases to explore for or use minerals, oil, natural gas and similar nonregenerative resources, including the intangible right to explore for those natural resources and rights to use the land in which those natural resources are contained. The guidance is effective for interim and annual periods beginning after December 15, 2018. This ASU is to be adopted using a modified retrospective approach. The Company plans to adopt this guidance effective January 1, 2019 and is currently evaluating the effect that adopting this guidance will have on its financial position, results of operations or cash flows.
Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, as a new Topic, ASC Topic 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606), which deferred the effective date of ASU No. 2014-09 by one year, making the new standard effective for interim and annual periods beginning after December 15, 2017. This ASU can be adopted either retrospectively or as a cumulative-effect adjustment as of the date of adoption.
Additionally, in March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus agent considerations (reporting revenue gross versus net), which clarifies the implementation guidance on principal versus agent considerations on such matters. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying performance obligations and licensing, which clarifies guidance related to identifying performance obligations and licensing implementation guidance contained in the new revenue recognition standard. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-scope improvements and practical expedients, which addresses narrow-scope improvements to the guidance on collectibility, non-cash consideration, and completed contracts at transition. Additionally, the amendments in this update provide a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which clarifies the guidance or corrects unintended application of guidance.

The Company plans to adopt this guidance effective January 1, 2018 using the modified retrospective method applied to contracts that are not completed as of that date. To date, the Company has not identified changes to its revenue recognition policies that would result in a material adjustment to the opening balance of retained earnings on January 1, 2018; however, it is continuing to evaluate the effect, if any, that adopting this guidance will have on its financial position, results of operations or cash flows. The Company is also evaluating its agreements with royalty and nonoperated partners for principal versus agent consideration. Adopting this guidance will result in increased disclosures related to revenue recognition policies and disaggregation of revenue. As allowed under Topic 606, the Company does not plan to disclose the value of unsatisfied performance obligations for contracts with variable consideration or with an original term of one year or less.
Statement of Cash Flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), which is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The guidance addresses eight specific cash flow issues for which current GAAP is either unclear or does not include specific guidance. The guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is permitted, provided that all of the amendments are adopted in the same period. This ASU must be adopted using a retrospective transition method.
Upon adopting this guidance, the Company will be required to make an accounting policy election to classify distributions it receives from its equity method investees under either (1) the cumulative earnings approach in which distributions received are considered returns on investment and classified as cash inflows from operating activities unless the cumulative distributions received exceed cumulative equity in earnings recognized by the Company, or (2) the nature of distributions approach in which distributions received are classified on the basis of the nature of the activity that generated the distribution as either a return on investment (cash inflows from operating activities) or a return of investment (cash inflows from investing activities). The Company has not yet determined which policy election it will make. Currently, the Company is not receiving any distributions from its equity method investees; therefore, the selection between the policy elections would not have a material effect on its presentation of cash flows. If material distributions are received in the future, the impact of the policy election could be material. The Company expects to adopt this guidance effective January 1, 2018 and is currently evaluating the effect that adopting the remaining areas of this guidance will have on its presentation of cash flows. Adoption of this guidance is not expected to have a material effect on the Company's financial position or results of operations.
2. Properties and Equipment, Net
Properties and equipment, net are comprised of the following:

Proved oil and gas properties, gathering and pipeline systems and accumulated depreciation, depletion and amortization decreased from December 31, 2016 to September 30, 2017 primarily as a result of the sale of assets in West Virginia, Virginia and Ohio discussed below.
At September 30, 2017, the Company did not have any projects that had exploratory well costs capitalized for a period of greater than one year after drilling.
Divestitures
In September 2017, the Company sold certain proved and unproved oil and gas properties and related pipeline assets located in West Virginia, Virginia and Ohio for $41.3 million, subject to customary purchase price adjustments. During the second quarter of 2017, the Company classified these assets as held for sale and recorded an impairment charge of $68.6 million associated with the proposed sale of these properties. Upon closing the sale in the third quarter of 2017, the Company recognized a loss on sale of oil and gas properties of $11.9 million.

The fair value of the impaired properties was determined using a market approach that took into consideration the expected sales price included in the purchase and sale agreement the Company executed on June 30, 2017. Accordingly, the inputs associated with the fair value of these assets were considered Level 3 in the fair value hierarchy. Refer to Note 1 of the Notes to the Consolidated Financial Statements in the Form 10-K for a description of the fair value hierarchy.
In February 2016, the Company completed the divestiture of certain proved and unproved oil and gas properties in east Texas for approximately $56.4 million resulting in a $0.5 million gain on sale of assets.

Constitution
On April 22, 2016, Constitution announced that the New York State Department of Environmental Conservation (NYSDEC) denied Constitution's application for a Section 401 Water Quality Certification (Certification) for the New York State portion of its proposed 126-mile route. During the second quarter of 2016, Constitution filed legal actions in the U.S. Court of Appeals for the Second Circuit and the U.S. District Court for the Northern District of New York challenging the legality and appropriateness of the NYSDEC’s decision. On March 16, 2017, the U.S. District Court for the Northern District of New York issued an order ruling, without prejudice, that it lacked subject matter jurisdiction to hear Constitution’s complaint. On August 18, 2017, the Second Circuit issued a decision denying in part and dismissing in part Constitution’s appeal. The Second Circuit determined that it lacked jurisdiction to address Constitution’s argument that the NYSDEC waived its ability to issue a Certification by unreasonably delaying action on Constitution's application. Instead, the Second Circuit found that jurisdiction over the waiver issue lies exclusively with the United States Court of Appeals for the District of Columbia Circuit. The Second Circuit, however, rejected Constitution’s assertion that the denial of the Certification by the NYSDEC was “arbitrary and capricious” and denied Constitution’s complaint in that regard. On October 11, 2017, Constitution filed a petition for a declaratory order requesting the Federal Energy Regulatory Commission (FERC) to find that, by operation of law, the Section 401 Water Quality Certification requirement for the New York State portion of the pipeline project was waived due to the failure of the NYSDEC to act on Constitution’s application within a reasonable period of time, as required by the Clean Water Act. The FERC has not yet ruled on this petition.
Constitution stated that it remains committed to pursuing the project and that it intends to pursue all available options to challenge the NYSDEC’s decision. In light of the current status of the litigation and the regulatory challenges, Constitution estimates its target in-service date to be as early as the first half of 2019. This assumes the timely receipt of a notice to proceed from the FER C and the timely receipt of all other state and federal permits required for the project.
In light of the NYSDEC’s denial and actions taken to challenge the denial, the Company evaluated its investment in Constitution for other-th an-temporary impairment (OTTI) as of September 30, 2017 and does not believe there is an indication of an OTTI. The Company’s evaluation considered various factors, including but not limited to prior FERC approval and the related economic viability of the project, the pending legal and regulatory actions filed by Constitution and the other members’ commitment to the project. To the extent that the legal and regulatory proceedings have unfavorable outcomes, or if Constitution concludes that the project is no longer viable or elects to not go forward as legal and regulatory actions progress, the Company will reevaluate the facts and circumstances relative to its conclusions with respect to OTTI. In the event that facts and circumstances change, the Company may be required to recognize an impairment charge up to its investment value at such time, net of any cash and working capital held by Constitution. The Company will continue to monitor the carrying value of its investment as required.

Total liabilities |  | $ | 24,169 |  |  | $ | 21,400 |  |  | $ | 18,859 |  |  | $ | 64,428 |

The Company’s investments associated with its deferred compensation plan consist of mutual funds and deferred shares of the Company’s common stock that are publicly traded and for which market prices are readily available.
The derivative instruments were measured based on quotes from the Company’s counterparties. Such quotes have been derived using an income approach that considers various inputs including current market and contractual prices for the underlying instruments, quoted forward prices for natural gas and crude oil, basis differentials, volatility factors and interest rates, such as a LIBOR curve for a similar length of time as the derivative contract term as applicable. Estimates are verified using relevant NYMEX futures contracts and/or are compared to multiple quotes obtained from counterparties for reasonableness. The determination of the fair values presented above also incorporates a credit adjustment for non-performance risk. The Company measured the non-performance risk of its counterparties by reviewing credit default swap spreads for the various financial institutions with which it has derivative transactions, while non-performance risk of the Company is evaluated using a market credit spread provided by the Company’s bank. The Company has not incurred any losses related to non-performance risk of its counterparties and does not anticipate any material impact on its financial results due to non-performance by third parties.
The most significant unobservable inputs relative to the Company’s Level 3 derivative contracts are basis differentials and volatility factors. An increase (decrease) in these unobservable inputs would result in an increase (decrease) in fair value, respectively. The Company does not have access to the specific assumptions used in its counterparties’ valuation models. Consequently, additional disclosures regarding significant Level 3 unobservable inputs were not provided.

Table of Contents
The following table sets forth a reconciliation of changes in the fair value of financial assets and liabilities classified as Level 3 in the fair value hierarchy:

|  | Nine Months Ended September 30,
(In thousands) |  | 2017 |  | 2016
Balance at beginning of period |  | $ | (15,868 | ) |  | $ | — |
Total gain (loss) included in earnings |  | 28,659 |  |  | 381 |

Change in unrealized gains (losses) relating to assets and liabilities still held at the end of the period |  | $ | 14,431 |  |  | $ | 464 |

There were no transfers between Level 1 and Level 2 fair value measurements for the nine months ended September 30, 2017 and 2016.
Non-Financial Assets and Liabilities
The Company discloses or recognizes its non-financial assets and liabilities, such as impairments, at fair value on a nonrecurring basis. The Company recorded an impairment charge related to certain oil and gas properties during the quarter ended June 30, 2017. Refer to Note 2 of the Notes to the Condensed Consolidated Financial Statements for additional disclosures related to fair value associated with the impaired assets. As none of the Company’s other non-financial assets and liabilities were measured at fair value as of September 30, 2017, additional disclosures were not required.
The estimated fair value of the Company’s asset retirement obligations at inception is determined by utilizing the income approach by applying a credit-adjusted risk-free rate, which takes into account the Company’s credit risk, the time value of money, and the current economic state to the undiscounted expected abandonment cash flows. Given the unobservable nature of the inputs, the measurement of the asset retirement obligations was classified as Level 3 in the fair value hierarchy.
Fair Value of Other Financial Instruments
The estimated fair value of other financial instruments is the amount at which the instrument could be exchanged currently between willing parties. The carrying amount reported in the Condensed Consolidated Balance Sheet for cash and cash equivalents approximates fair value due to the short-term maturities of these instruments. Cash and cash equivalents are classified as Level 1 in the fair value hierarchy and the remaining financial instruments are classified as Level 2.
The Company uses available market data and valuation methodologies to estimate the fair value of debt. The fair value of debt is the estimated amount the Company would have to pay a third party to assume the debt, including a credit spread for the difference between the issue rate and the period end market rate. The credit spread is the Company’s default or repayment risk. The credit spread (premium or discount) is determined by comparing the Company’s senior notes and revolving credit facility to new issuances (secured and unsecured) and secondary trades of similar size and credit statistics for both public and private debt. The fair value of all senior notes and the revolving credit facility is based on interest rates currently available to the Company. The Company’s debt is valued using an income approach and classified as Level 3 in the fair value hierarchy.
The carrying amount and fair value of debt is as follows:

|  | September 30, 2017 |  | December 31, 2016
(In thousands) |  | Carrying Amount |  | Estimated Fair Value |  | Carrying Amount |  | Estimated Fair Value
Debt, net |  | $ | 1,521,551 |  |  | $ | 1,536,360 |  |  | $ | 1,520,530 |  |  | $ | 1,463,643 |
Current maturities |  | (237,000 | ) |  | (243,569 | ) |  | — |  |  | — |
Long-term debt, excluding current maturities |  | $ | 1,284,551 |  |  | $ | 1,292,791 |  |  | $ | 1,520,530 |  |  | $ | 1,463,643 |

7. Asset Retirement Obligations
Activity related to the Company’s asset retirement obligations is as follows:

(In thousands) |  | Nine Months Ended September 30, 2017
Balance at beginning of period |  | $ | 133,733 |
Liabilities incurred |  | 3,788 |

Liabilities divested |  | (75,014 | )
Accretion expense |  | 4,396 |
Balance at end of period |  | $ | 65,678 |

As of September 30, 2017 and December 31, 2016, approximately $6.1 million and $2.0 million, respectively, is included in accrued liabilities in the Condensed Consolidated Balance Sheet, which represents the current portion of the Company's asset retirement obligation.
8. Commitments and Contingencies
Contractual Obligations
The Company has various contractual obligations in the normal course of its operations. There have been no material changes to the Company’s contractual obligations described under “Transportation and Gathering Agreements,” “Drilling Rig Commitments,” “Lease Commitments” and “Hydraulic Fracturing Services Commitments” as disclosed in Note 9 in the Notes to Consolidated Financial Statements in the Form 10-K.
Legal Matters
The Company is a defendant in various legal proceedings arising in the normal course of business. All known liabilities are accrued when management determines they are probable based on its best estimate of the potential loss. While the outcome and impact of these legal proceedings on the Company cannot be predicted with certainty, management believes that the resolution of these proceedings will not have a material effect on the Company’s financial position, results of operations or cash flows.
Contingency Reserves
When deemed necessary, the Company establishes reserves for certain legal proceedings. The establishment of a reserve is based on an estimation process that includes the advice of legal counsel and subjective judgment of management. While management believes these reserves to be adequate, it is reasonably possible that the Company could incur additional losses with respect to those matters in which reserves have been established. The Company believes that any such amount above the amounts accrued would not be material to the Condensed Consolidated Financial Statements. Future changes in facts and circumstances not currently foreseeable could result in the actual liability exceeding the estimated ranges of loss and amounts accrued.

In September 2017, in conjunction with its sale of properties located in West Virginia, Virginia and Ohio, the Company terminated approximately 100 employees. As a result, the employees’ participation in the postretirement plan terminated, which resulted in a remeasurement and curtailment of the postretirement benefit obligation at September 30, 2017.
The change in benefit obligation for the nine months ended September 30, 2017 also reflects a plan amendment for the Company's change from a Medicare Supplemental program to a Medicare Advantage program for participants age 65 and older. This coverage continues to be provided under a fully-insured arrangement.

10. Capital Stock
Treasury Stock
In August 1998, the Board of Directors authorized a share repurchase program under which the Company may purchase shares of common stock in the open market or in negotiated transactions. The timing and amount of any stock purchases are determined at the discretion of management. The Company may use the repurchased shares to fund stock compensation programs currently in existence, or for other corporate purposes. All purchases executed to date have been through open market transactions. There is no expiration date associated with the authorization to repurchase common stock of the Company.
During the first nine months of 2017, the Company repurchased 3.0 million shares for a total cost of $68.3 million. Since the authorization date, the Company has repurchased 32.9 million shares of the 40.0 million total shares authorized for a total cost of approximately $456.6 million, of which 20.0 million shares have been retired. No treasury shares have been delivered or sold by the Company subsequent to the repurchase. As of September 30, 2017, 12.9 million shares were held as treasury stock.
11. Stock-based Compensation
General
From time to time the Company grants certain stock-based compensation awards, including restricted stock awards, restricted stock units and performance share awards. Stock-based compensation expense associated with these awards was $7.8 million and $5.1 million in the third quarter of 2017 and 2016, respectively, and $26.2 million and $23.0 million during the first nine months of 2017 and 2016, respectively. Stock-based compensation expense is included in general and administrative expense in the Condensed Consolidated Statement of Operations.
As described in Note 1 to the Condensed Consolidated Financial Statements, effective January 1, 2017, the Company adopted ASU No. 2016-09, which requires that excess tax benefits and tax deficiencies on stock-based compensation be recorded in the income statement. During the first nine months of 2017, the Company recorded an increase to tax expense of $2.6 million in the Condensed Consolidated Statement of Operations as a result of book compensation cost for employee stock-based compensation exceeding the federal and state tax deductions for awards that vested during the period.
Prior to the adoption of ASU No. 2016-09, windfall tax benefits were recorded in additional paid in capital in the Condensed Consolidated Balance Sheet and tax shortfalls reduced additional paid in capital to the extent they offset previously recorded windfall tax benefits. During the first nine months of 2016, the Company recorded a tax shortfall of $2.1 million, resulting in a reduction of the Company's windfall tax benefit that was recorded in additional paid in capital in the Condensed Consolidated Balance Sheet. The tax shortfall was a result of book compensation cost for employee stock-based compensation exceeding the federal and state tax deductions for certain awards that vested during the period.
Refer to Note 13 of the Notes to the Consolidated Financial Statements in the Form 10-K for further description of the various types of stock-based compensation awards and the applicable award terms.

Table of Contents
Restricted Stock Units
During the first nine months of 2017, 57,028 restricted stock units were granted to non-employee directors of the Company with a weighted-average grant date value of $22.94 per unit. The fair value of these units is measured based on the closing stock price on grant date and compensation expense is recorded immediately. These units immediately vest and are issued when the director ceases to be a director of the Company.
Performance Share Awards
The performance period for the awards granted during the first nine months of 2017 commenced on January 1, 2017 and ends on December 31, 2019. The Company used an annual forfeiture rate assumption ranging from 0% to 6% for purposes of recognizing stock-based compensation expense for its performance share awards.
Performance Share Awards Based on Internal Performance Metrics
The fair value of performance share award grants based on internal performance metrics is based on the closing stock price on the grant date. Each performance share award represents the right to receive up to 100% of the award in shares of common stock. Based on the Company’s probability assessment at September 30, 2017, it is considered probable that the criteria for all performance awards based on internal metrics awards will be met.
Employee Performance Share Awards. During the first nine months of 2017, 406,460 Employee Performance Share Awards were granted at a grant date value of $22.60 per share. The performance metrics are set by the Company’s compensation committee and are based on the Company’s average production, average finding costs and average reserve replacement over a three-year performance period.
Hybrid Performance Share Awards. During the first nine months of 2017, 272,920 Hybrid Performance Share Awards were granted at a grant date value of $22.60 per share. The 2017 awards vest 25% on each of the first and second anniversary dates and 50% on the third anniversary, provided that the Company has $100 million or more of operating cash flow for the year preceding the vesting date, as set by the Company’s compensation committee. If the Company does not meet the performance metric for the applicable period, then the portion of the performance shares that would have been issued on that anniversary date will be forfeited.
Performance Share Awards Based on Market Conditions
These awards have both an equity and liability component, with the right to receive up to the first 100% of the award in shares of common stock and the right to receive up to an additional 100% of the value of the award in excess of the equity component in cash. The equity portion of these awards is valued on the grant date and is not marked to market, while the liability portion of the awards is valued as of the end of each reporting period on a mark-to-market basis. The Company calculates the fair value of the equity and liability portions of the awards using a Monte Carlo simulation model.
TSR Performance Share Awards. During the first nine months of 2017, 409,380 TSR Performance Share Awards were granted and are earned, or not earned, based on the comparative performance of the Company’s common stock measured against a predetermined group of companies in the Company’s peer group over a three-year performance period.
The following assumptions were used to determine the grant date fair value of the equity component (February 22, 2017) and the period-end fair value of the liability component of the TSR Performance Share Awards:

|  | Grant Date |  | September 30, 2017
Fair value per performance share award |  | $ | 19.85 |  |  | $12.28-$20.22
Assumptions: |  |  |  |  |
Stock price volatility |  | 37.8 | % |  | 20.8% - 39.9%
Risk free rate of return |  | 1.4 | % |  | 1.1% - 1.5%

12. Earnings per Common Share
Basic earnings per share (EPS) is computed by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted EPS is similarly calculated except that the common shares outstanding for the period is increased using the treasury stock method to reflect the potential dilution that could occur if outstanding stock appreciation rights were exercised and stock awards were vested at the end of the applicable period. Anti-dilutive shares represent potentially dilutive securities that are excluded from the computation of diluted income or loss per share as their impact would be anti-dilutive.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following review of operations for the three and nine month periods ended September 30, 2017 and 2016 should be read in conjunction with our Condensed Consolidated Financial Statements and the Notes included in this Form 10-Q and with the Consolidated Financial Statements, Notes and Management’s Discussion and Analysis included in the Cabot Oil & Gas Corporation Annual Report on Form 10-K for the year ended December 31, 2016 (Form 10-K).
OVERVIEW
Financial and Operating Overview
Financial and operating results for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 are as follows:

• | Equivalent production increase d 49.7 Bcfe, or 11%, from 463.0 Bcfe, or 1,689.6 Mmcfe per day, in 2016 to 512.7 Bcfe, or 1,877.9 Mmcfe per day, in 2017.

• | Natural gas production increase d 49.4 Bcf, or 11%, from 441.8 Bcf in 2016 to 491.2 Bcf in 2017, as a result of drilling and completion activities in Pennsylvania.

• | Crude oil/condensate/NGL production increase d 0.1 Mmbbls, or 2%, from 3.5 Mmbbls in 2016 to 3.6 Mmbbls in 2017, as result of an increase in drilling and completion activity in south Texas partially offset by a natural decline in production.

• | Average realized natural gas price was $2.35 per Mcf, 45% higher than the $1.62 per Mcf realized in the comparable period of the prior year.

• | Average realized crude oil price was $45.70 per Bbl, 27% higher than the $35.85 per Bbl realized in the comparable period of the prior year.

• | Total capital expenditures were $582.8 million compared to $262.1 million in the comparable period of the prior year.

• | Drilled 71 gross wells (62.5 net) with a success rate of 98.6% compared to 28 gross wells (28.0 net) with a success rate of 100% for the comparable period of the prior year.

• | Completed 81 gross wells (70.2 net) in 2017 compared to 51 gross wells (51.0 net) in 2016.

• | Average rig count during 2017 was approximately 2.0 rigs in the Marcellus Shale, approximately 1.0 rig in the Eagle Ford Shale and approximately 0.2 rigs in other areas, compared to an average rig count in the Marcellus Shale of approximately 1.1 rigs and approximately 0.3 rigs in the Eagle Ford Shale in 2016.

• | Received proceeds of $32.7 million primarily related to the divestiture of certain oil and gas properties and related pipeline assets in West Virginia, Virginia and Ohio.

• | Repurchased 3.0 million shares of our common stock for a total cost of $68.3 million.

Market Conditions and Commodity Prices
Our financial results depend on many factors, particularly the price of natural gas and crude oil and our ability to market our production on economically attractive terms. Commodity prices are affected by many factors outside of our control, including changes in market supply and demand, which are impacted by pipeline capacity constraints, inventory storage levels, basis differentials, weather conditions and other factors. In addition, our realized prices are further impacted by our hedging activities. Location differentials have improved in certain regions, such as in the Appalachian region, resulting in further increases in natural gas prices. As a result, we cannot accurately predict future commodity prices and, therefore, cannot determine with any degree of certainty what effect increases or decreases in these prices will have on our capital program, production volumes or revenues. We expect natural gas and crude oil prices to remain volatile. In addition to production volumes and commodity prices, finding and developing sufficient amounts of natural gas and crude oil reserves at economical costs are critical to our long-term success. For information about the impact of realized commodity prices on our natural gas and crude oil and condensate revenues, refer to “Results of Operations” below.
We account for our derivative instruments on a mark-to-market basis with changes in fair value recognized in operating revenues in the Condensed Consolidated Statement of Operations. As a result of these mark-to-market adjustments, we will

likely experience volatility in our earnings due to commodity price volatility. Refer to “Impact of Derivative Instruments on Operating Revenues” below and Note 5 to the Condensed Consolidated Financial Statements for more information.
Commodity prices have remained volatile but have improved during 2017 compared to the fourth quarter of 2016. In the event that commodity prices significantly decline, management would test the recoverability of the carrying value of its oil and gas properties and, if necessary, record an impairment charge.
We believe that we are well-positioned to manage the challenges presented in a depressed commodity pricing environment, and that we can endure the continued volatility in current and future commodity prices by:

• | Continuing to exercise discipline in our capital program with the expectation of funding our capital expenditures with cash on hand, operating cash flows, and if required, borrowings under our revolving credit facility.

• | Continuing to optimize our drilling, completion and operational efficiencies, resulting in lower operating costs per unit of production.

• | Continuing to manage our balance sheet, which provides sufficient availability under our revolving credit facility and existing cash balances to meet our capital requirements and maintain compliance with our debt covenants.

• | Continuing to manage price risk by strategically hedging our natural gas and crude oil production.

Outlook
Based on the expectation for higher operating cash flow due to an improvement in the commodity price outlook, we increased our 2017 budgeted capital expenditures compared to 2016. Our full year 2017 capital spending program includes approximately $775.0 million in capital expenditures related to our drilling and completion program, leasehold acquisitions and contributions of approximately $70.0 million to our equity method investments. All such expenditures are expected to be funded by existing cash, operating cash flow and if required, borrowings under our revolving credit facility.
In 2016, we drilled 40 gross wells (38.0 net) and completed 76 gross wells (76.0 net), of which 62 gross wells (62.0 net) were drilled but uncompleted in prior years. In 2017, we plan to drill 100 gross wells (95.0 net) and complete 95 gross wells (90.0 net), of which 51 gross wells (45.0 net) were drilled but uncompleted in prior years. In 2017, we plan to operate an average of approximately 3.0 rigs, an increase from an average of approximately 1.4 rigs in 2016. We will continue to assess the natural gas and crude oil price environment along with our liquidity position and may increase or decrease our capital expenditures accordingly.
Financial Condition
Capital Resources and Liquidity
Our primary sources of cash for the nine months ended September 30, 2017 were from the sale of natural gas and crude oil production and proceeds from the sale of assets. These cash flows were primarily used to fund our capital expenditures (including contributions to our equity method investments), interest payments on debt, repurchase of shares of our common stock and payment of dividends. See below for additional discussion and analysis of cash flow.
The borrowing base under the terms of our revolving credit facility is redetermined annually in April. In addition, either we or the banks may request an interim redetermination twice a year or in connection with certain acquisitions or divestitures of oil and gas properties. Effective April 11, 2017, the borrowing base and available commitments were reaffirmed at $3.2 billion and $1.7 billion, respectively. There were no borrowings outstanding under our revolving credit facility as of September 30, 2017.
We strive to manage our debt at a level below the available credit line in order to maintain borrowing capacity. Our revolving credit facility includes a covenant limiting our total debt. We believe that, with the existing cash on hand, operating cash flow and availability under our revolving credit facility, we have the capacity to fund our spending plans.
At September 30, 2017, we were in compliance with all restrictive financial covenants for both the revolving credit facility and senior notes. As of September 30, 2017, based on our asset coverage and leverage ratios, there were no interest rate adjustments required for our senior notes. See our Form 10-K for further discussion of our restrictive financial covenants.

Cash Flows
Our cash flows from operating, investing and financing activities are as follows:

|  | Nine Months Ended September 30,
(In thousands) |  | 2017 |  | 2016
Cash flows provided by operating activities |  | $ | 719,047 |  |  | $ | 257,705 |
Cash flows used in investing activities |  | (577,484 | ) |  | (220,141 | )
Cash flows provided by (used in) financing activities |  | (129,849 | ) |  | 463,115 |
Net increase in cash and cash equivalents |  | $ | 11,714 |  |  | $ | 500,679 |

Operating Activities. Operating cash flow fluctuations are substantially driven by commodity prices, changes in our production volumes and operating expenses. Prices for natural gas and crude oil have historically been volatile, primarily as a result of supply and demand for natural gas and crude oil, pipeline infrastructure constraints, basis differentials, inventory storage levels and seasonal influences. In addition, fluctuations in cash flow may result in an increase or decrease in our capital expenditures. We are unable to predict future commodity prices and, as a result, cannot provide any assurance about future levels of net cash provided by operating activities.
Our working capital is substantially influenced by the variables discussed above and fluctuates based on the timing and amount of borrowings and repayments under our revolving credit facility, repayments of debt, the timing of cash collections and payments on our trade accounts receivable and payable, respectively, sales and repurchases of our securities and changes in the fair value of our commodity derivative activity. From time to time, our working capital will reflect a deficit, while at other times it will reflect a surplus. This fluctuation is not unusual. At September 30, 2017 and December 31, 2016, we had a working capital surplus of $279.8 million and $458.1 million, respectively.
Net cash provided by operating activities in the first nine months of 2017 increase d by $461.3 million compared to the first nine months of 2016. This increase was primarily due to higher operating revenues, partially offset by higher cash operating expenses. The increase in operating revenues was primarily due to an increase in realized natural gas and crude oil prices and higher equivalent production. Average realized natural gas and crude oil prices increase d by 45% and 27%, respectively, for the first nine months of 2017 compared to the first nine months of 2016. Equivalent production increase d by 11% for the first nine months of 2017 compared to the first nine months of 2016 driven by higher natural gas production in the Marcellus Shale.
See “Results of Operations” for additional information relative to commodity price, production and operating expense fluctuations.
Investing Activities. Cash flows used in investing activities increase d by $357.3 million for the first nine months of 2017 compared to the first nine months of 2016. The increase was due to $341.8 million higher capital expenditures and $16.4 million lower proceeds from the sale of assets, partially offset by $0.8 million lower capital contributions associated with our equity method investments.
Financing Activities. Cash flows provided by financing activities decrease d by $593.0 million for the first nine months of 2017 compared to the first nine months of 2016. This decrease was primarily due to $995.3 million lower net proceeds from the issuance of common stock in 2016, $68.3 million of repurchases of our common stock in 2017 and $28.8 million of higher dividend payments related to an increase in the dividend rate and the issuance of common stock in 2016. These decreases were partially offset by $497.0 million of lower net repayments of debt due to the repayment of the outstanding balance on our revolving credit facility and certain of our senior notes with the proceeds from the issuance of common stock in 2016.

For the full year of 2017, we plan to drill approximately 100 gross wells (95.0 net) and complete 95 gross wells (90.0 net), of which 51 gross wells (45.0 net) were drilled but uncompleted in prior years. In 2017, our drilling program includes approximately $775.0 million in total capital expenditures compared to $372.5 million in 2016. See “Outlook” for additional information regarding the current year drilling program. We will continue to assess the natural gas and crude oil price environment along with our liquidity position and may increase or decrease our capital expenditures accordingly.

Results of Operations
Third Quarter s of 2017 and 2016 Compared
We reported net income in the third quarter of 2017 of $17.6 million, or $0.04 per share, compared to a net loss of $10.3 million, or $0.02 per share, in the third quarter of 2016. The increase in net income was primarily due to higher operating revenues, partially offset by higher operating expenses, loss on sale of assets and income tax expense.
Revenue, Price and Volume Variances

Total costs and expenses from operations increase d by $28.3 million, or 9%, in the third quarter of 2017 compared to the same period of 2016. The primary reasons for this fluctuation are as follows:

• | Direct operations increase d $1.7 million largely due to an increase in operating costs primarily driven by higher production, partially offset by improved operational efficiencies.

• | Transportation and gathering increase d $12.2 million due to higher throughput as a result of higher Marcellus Shale production.

• | Brokered natural gas decrease d $0.1 million. See the preceding table titled “Brokered Natural Gas” for further analysis.

• | Taxes other than income increase d $0.4 million primarily due to $0.9 million higher production taxes resulting from higher crude oil prices and production in south Texas, partially offset by $0.6 million lower drilling impact fees as a result of lower rates. The remaining changes in taxes other than income were not individually significant.

• | Exploration increase d $3.5 million primarily as a result of higher geophysical costs of $2.0 million

• | Depreciation, depletion and amortization increase d $6.8 million, primarily due to higher amortization of unproved properties of $9.4 million, partially offset by lower DD&A of $1.4 million in the third quarter of 2017. The increase in amortization of unproved properties is primarily due to an increase in leasing activity and an increase in amortization rates. The decrease in DD&A was due to a decrease of $17.3 million due to a lower DD&A rate of $0.75 per Mcfe for the third quarter of 2017 compared to $0.85 per Mcfe for the third quarter of 2016 primarily due to positive reserve revisions and the impairment of oil and gas properties and related pipeline assets in West Virginia and Virginia in 2016, partially offset by an increase of $15.8 million associated with higher equivalent production primarily in Pennsylvania for the third quarter of 2017 compared to the third quarter of 2016.

• | General and administrative increase d $3.9 million due to $3.2 million of severance costs for employees terminated as a result of the sale of properties located in West Virginia, Virginia and Ohio and $2.7 million of higher stock-based compensation expense associated with certain of our market-based performance awards, partially offset by $2.0 million lower professional services. The remaining changes in other general and administrative expenses were not individually significant.

Earnings (Loss) on Equity Method Investments
The increase in loss on equity method investments is a result of our proportionate share of net loss from our equity method investments in 2017 compared to 2016.
Loss on Sale of Assets
Loss on sale of assets increased $10.6 million due to the Company's sale of certain proved and unproved oil and gas properties and related pipeline assets located in West Virginia, Virginia and Ohio in the third quarter of 2017.
Other Expense (Income)
Other income increased $5.5 million primarily due to the curtailment gain on postretirement benefits as a result of the termination of approximately 100 employees in West Virginia, Virginia and Ohio.
Interest Expense, net
Interest expense, net decrease d $1.2 million due to $0.8 million higher interest income.
Income Tax Expense (Benefit)
Income tax expense increase d $15.2 million primarily due to higher pretax income, partially offset by a lower effective tax rate. The effective tax rates for the third quarter of 2017 and 2016 were 28.9% and 43.9%, respectively. The decrease in the effective tax rate is primarily due to a decrease in the blended state statutory tax rate as a result of changes in our state apportionment factors in the states in which we operate, as well as non-recurring discrete items recorded during the third quarter of 2017 versus the third quarter of 2016.
First Nine Months of 2017 and 2016 Compared
We reported net income in the first nine months of 2017 of $144.8 million, or $0.31 per share, compared to a net loss of $124.4 million, or $0.27 per share, in the first nine months of 2016. The increase in net income was primarily due to higher operating revenues, partially offset by higher operating expenses, loss on sale of assets and income tax expense.

Total costs and expenses from operations increase d by $98.2 million, or 10%, in the first nine months of 2017 compared to the same period of 2016. The primary reasons for this fluctuation are as follows:

• | Direct operations increase d $1.0 million largely due to an increase in operating costs primarily driven by higher production, partially offset by improved operational efficiencies, cost reductions from service providers and suppliers in 2017 compared to 2016.

• | Transportation and gathering increase d $39.0 million due to higher throughput as a result of higher Marcellus Shale production.

• | Brokered natural gas increase d $2.7 million. See the preceding table titled “Brokered Natural Gas” for further analysis.

• | Taxes other than income increase d $2.8 million due to $3.4 million higher production taxes primarily resulting from higher natural gas and crude oil prices and an increase in drilling impact fees of $1.9 million due to an increase in drilling activity in Pennsylvania. These increases were offset by a decrease of $2.4 million in ad valorem taxes as a result of lower property values primarily in south Texas.

• | Exploration increase d $3.5 million as a result of higher dry hole costs of $2.8 million in 2017 and $2.6 million higher geophysical costs, partially offset by lower charges related to the release of certain drilling rig contracts in south Texas. In the first nine months of 2016, we recorded rig termination charges of $1.7 million. We recorded no rig termination charges in the first nine months of 2017.

• | Depreciation, depletion and amortization decrease d $23.2 million, primarily due to lower DD&A of $38.0 million, partially offset by higher amortization of unproved properties of $15.9 million in 2017. The decrease in DD&A was due to a decrease of $82.5 million due to a lower DD&A rate of $0.73 per Mcfe for the first nine months of 2017 compared to $0.89 per Mcfe for the first nine months of 2016, partially offset by a $44.5 million increase due to higher equivalent production volumes. The lower DD&A rate was primarily due to positive reserve revisions and the impairment of oil and gas properties and related pipeline assets in West Virginia and Virginia in 2016. The increase in amortization of unproved properties is primarily due to the ongoing evaluation of our unproved properties and an increase in leasing activity.

Table of Contents

• | Impairment of oil and gas properties was $68.6 million in 2017 due to the impairment of oil and gas properties and related pipeline assets in West Virginia and Virginia.

• | General and administrative increase d $3.7 million due to $3.4 million higher employee-related expenses, $3.2 million of higher stock-based compensation expense associated with certain of our market-based performance awards and $3.2 million of severance costs for employees terminated as a result of its sale of properties located in West Virginia, Virginia and Ohio. These increases were partially offset by $6.8 million lower professional services. The remaining changes in other general and administrative expenses were not individually significant.

Earnings (Loss) on Equity Method Investments
The increase in loss on equity method investments is the result of our proportionate share of net earnings from our equity method investments in 2017 compared to 2016.
Loss on Sale of Assets
Loss on sale of assets increased $12.7 million due to the Company's sale of certain proved and unproved oil and gas properties and related pipeline assets located in West Virginia, Virginia and Ohio in the third quarter of 2017.
Other Expense (Income)
Other income increased $6.2 million primarily due to the curtailment gain on postretirement benefits as a result of the termination of approximately 100 employees in West Virginia, Virginia and Ohio.
Interest Expense, net
Interest expense, net decrease d $6.1 million primarily due to a $1.4 million increase in interest income and a $2.1 million decrease resulting from the repayment of the outstanding borrowings under our revolving credit facility in March 2016, which has remained undrawn through September 30, 2017. Interest expense also decreased $2.4 million resulting from the repurchase of $64.0 million of our 6.51% weighted-average senior notes in May 2016 and the repayment of $20.0 million of our 7.33% weighted-average senior notes in July 2016.
Loss on Debt Extinguishment
A $4.7 million debt extinguishment loss was recognized in the second quarter of 2016 related to the premium paid for the repurchase of a portion of our 6.51% weighted-average senior notes in May 2016 and the write-off of a portion of the associated deferred financing costs due to early repayment.
Income Tax Expense (Benefit)
Income tax expense increase d $157.2 million due to higher pretax income and a higher effective tax rate. The effective tax rates for the first nine months of 2017 and 2016 were 37.2% and 36.4%, respectively. The increase in the effective tax rate is primarily due to an increase in the blended state statutory tax rate as a result of changes in our state apportionment factors in the states in which we operate and the impact of excess tax benefits and tax deficiencies on shares vesting during the period as a result of the adoption of ASU No. 2016-09 in January 2017, partially offset by non-recurring discrete items recorded during the first nine months of 2017 versus the first nine months of 2016.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk
Market Risk
Our primary market risk is exposure to natural gas and crude oil prices. Realized prices are mainly driven by worldwide prices for crude oil and spot market prices for North American natural gas production. Commodity prices can be volatile and unpredictable.
Derivative Instruments and Risk Management Activities
Our risk management strategy is designed to reduce the risk of price volatility for our production in the natural gas and crude oil markets through the use of commodity derivatives. A committee that consists of members of senior management oversees our risk management activities. Our commodity derivatives generally cover a portion of our production and provide only partial price protection by limiting the benefit to us of increases in prices, while protecting us in the event of price declines. Further, if any of our counterparties defaulted, this protection might be limited as we might not receive the full benefit of our commodity derivatives. Please read the discussion below as well as Note 6 of the Notes to the Consolidated Financial Statements in our Form 10-K for a more detailed discussion of our derivative and risk management activities.
Periodically, we enter into commodity derivatives including collar, swap and basis swap agreements, to protect against exposure to price declines related to our natural gas and crude oil production. Our credit agreement restricts our ability to enter into commodity derivatives other than to hedge or mitigate risks to which we have actual or projected exposure or as permitted under our risk management policies and not subjecting us to material speculative risks. All of our derivatives are used for risk management purposes and are not held for trading purposes. Under the collar agreements, if the index price rises above the ceiling price, we pay the counterparty. If the index price falls below the floor price, the counterparty pays us. Under the swap agreements, we receive a fixed price on a notional quantity of natural gas or crude oil in exchange for paying a variable price based on a market-based index, such as the NYMEX gas and crude oil futures.
As of September 30, 2017, we had the following outstanding commodity derivatives:

|  |  |  |  |  |  | Collars |  |  |  | Basis Swaps |  | Estimated Fair Value Asset (Liability) (In thousands)
|  |  |  |  |  |  | Floor |  | Ceiling |  | Swaps |  |
Type of Contract |  | Volume |  | Contract Period |  | Range |  | Weighted- Average |  | Range |  | Weighted- Average |  | Weighted- Average |  | Weighted- Average |
Natural gas - NYMEX |  | 8.9 |  | Bcf |  | Oct. 2017 - Dec. 2017 |  |  |  |  |  |  |  |  |  | $ | 3.12 |  |  |  |  | $ | (177 | )
Natural gas - TCO |  | 4.5 |  | Bcf |  | Oct. 2017 - Dec. 2017 |  |  |  |  |  |  |  |  |  | $ | 3.46 |  |  |  |  | 2,322 |
Natural gas - NYMEX |  | 8.9 |  | Bcf |  | Oct. 2017 - Dec. 2017 |  | $ | — |  |  | $ | 3.09 |  |  | $3.42-$3.45 |  | $ | 3.43 |  |  |  |  |  |  | 261 |
Natural gas - Transco |  | 21.3 |  | Bcf |  | Jan. 2018 - Dec. 2019 |  |  |  |  |  |  |  |  |  |  |  | $ | 0.42 |  |  | 2,858 |
Crude oil |  | 0.5 |  | Mmbbl |  | Oct. 2017 - Dec. 2017 |  | $ | — |  |  | $ | 50.00 |  |  | $56.25-$56.50 |  | $ | 56.39 |  |  |  |  |  |  | 259 |
|  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  | $ | 5,523 |

In the above table, natural gas prices are stated per Mcf and crude oil prices are stated per barrel.
The amounts set forth in the table above represent our total unrealized derivative position at September 30, 2017 and exclude the impact of non-performance risk. Non-performance risk is considered in the fair value of our derivative instruments that are recorded in our Condensed Consolidated Financial Statements and is primarily evaluated by reviewing credit default swap spreads for the various financial institutions with which we have derivative contracts, while our non-performance risk is evaluated using a market credit spread provided by one of our banks.
During the first nine months of 2017, natural gas collars with floor prices of $3.09 per Mcf and ceiling prices ranging from $3.42 to $3.45 per Mcf covered 26.5 Bcf, or 5%, of natural gas production at an average price of $3.23 per Mcf. Natural gas swaps covered 38.3 Bcf, or 8%, of natural gas production at an average price of $3.23 per Mcf. Crude oil collars with floor prices of $50.00 per Bbl and ceiling prices ranging from $56.25 to $56.50 per Bbl covered 1.4 Mmbbl, or 43%, of crude oil production at an average price of $50.77 per Bbl.
We are exposed to market risk on commodity derivative instruments to the extent of changes in market prices of natural gas and crude oil. However, the market risk exposure on these derivative contracts is generally offset by the gain or loss recognized upon the ultimate sale of the commodity. Although notional contract amounts are used to express the volume of

natural gas agreements, the amounts that can be subject to credit risk in the event of non-performance by third parties are substantially smaller. Our counterparties are primarily commercial banks and financial service institutions that management believes present minimal credit risk and our derivative contracts are with multiple counterparties to minimize our exposure to any individual counterparty. We perform both quantitative and qualitative assessments of these counterparties based on their credit ratings and credit default swap rates where applicable. We have not incurred any losses related to non-performance risk of our counterparties and we do not anticipate any material impact on our financial results due to non-performance by third parties. However, we cannot be certain that we will not experience such losses in the future.
The preceding paragraphs contain forward-looking information concerning future production and projected gains and losses, which may be impacted both by production and by changes in the future commodity prices. See “Forward-Looking Information” for further details.
Fair Value of Other Financial Instruments
The estimated fair value of other financial instruments is the amount at which the instrument could be exchanged currently between willing parties. The carrying amount reported in the Condensed Consolidated Balance Sheet for cash and cash equivalents approximates fair value due to the short-term maturities of these instruments.
We use available market data and valuation methodologies to estimate the fair value of debt. The fair value of debt is the estimated amount we would have to pay a third party to assume the debt, including a credit spread for the difference between the issue rate and the period end market rate. The credit spread is our default or repayment risk. The credit spread (premium or discount) is determined by comparing our senior notes and revolving credit facility to new issuances (secured and unsecured) and secondary trades of similar size and credit statistics for both public and private debt. The fair value of all senior notes and the revolving credit facility is based on interest rates currently available to us.
The carrying amount and fair value of debt is as follows:

|  | September 30, 2017 |  | December 31, 2016
(In thousands) |  | Carrying Amount |  | Estimated Fair Value |  | Carrying Amount |  | Estimated Fair Value
Debt, net |  | $ | 1,521,551 |  |  | $ | 1,536,360 |  |  | $ | 1,520,530 |  |  | $ | 1,463,643 |
Current maturities |  | (237,000 | ) |  | (243,569 | ) |  | — |  |  | — |
Long-term debt, excluding current maturities |  | $ | 1,284,551 |  |  | $ | 1,292,791 |  |  | $ | 1,520,530 |  |  | $ | 1,463,643 |
