Summary of Significant Accounting Policies

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES –

Basis of Presentation

These unaudited consolidated financial statements include the accounts of Comstock and its wholly-owned subsidiaries. In management's opinion, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the financial position of Comstock Resources, Inc. and its subsidiaries (collectively, "Comstock" or the "Company") as of September 30, 2018, and the related results of operations and cash flows for the Predecessor and Successor periods being presented. Net loss and comprehensive loss are the same in all periods presented. All adjustments are of a normal recurring nature unless otherwise disclosed.

The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted pursuant to those rules and regulations, although Comstock believes that the disclosures made are adequate to make the information presented not misleading. These unaudited consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in Comstock's Annual Report on Form 10-K for the year ended December 31, 2017.

The results of operations for the Predecessor and Successor periods up to and through September 30, 2018 are not necessarily an indication of the results expected for the full year.

On August 14, 2018, Arkoma Drilling, L.P. and Williston Drilling, L.P. (collectively, the "Jones Partnerships") contributed certain oil and gas properties in North Dakota and Montana (the "Bakken Shale Properties") in exchange for common stock representing 84% of the Company's outstanding common stock (the "Jones Contribution"). The Jones Partnerships are wholly owned and controlled by Dallas businessman Jerry Jones and his children (collectively, the "Jones Group"). The Jones Partnerships received 88,571,429 newly issued shares of common stock based on an agreed upon share price of $7.00 per share.

The Company assessed the Bakken Shale Properties to determine whether they meet the definition of a business under US generally accepted accounting principles, determining that they do not meet the definition of a business. As a result, the Jones Contribution is not being accounted for as a business combination. Upon the issuance of the shares of Comstock common stock, the Jones Group obtained control over Comstock through their ownership of the Jones Partnerships. Through the Jones Partnerships, the Jones Group owns a majority of the voting common stock as well as the ability to control the composition of the majority of the board of directors of Comstock. As a result of the change of control that occurred upon the issuance of the common stock, the Jones Group controls Comstock and, thereby, continues to control the Bakken Shale Properties.

Accordingly, the basis of the Bakken Shale Properties recognized by Comstock is the historical basis of the Jones Group. The historical cost basis of the Bakken Shale properties contributed was $397.6 million, which was comprised of $554.3 million of capitalized costs less $156.7 million of accumulated depletion, depreciation and amortization. The change in control of Comstock results in a new basis for Comstock as the company has elected to apply pushdown accounting pursuant to ASC 805, Business Combinations. The new basis is pushed down to Comstock for financial reporting purposes, resulting in Comstock's assets, liabilities and equity accounts being recognized at fair value upon the closing of the Jones Transactions.

References to "Successor" or "Successor Company" relate to the financial position and results of operations of the Company subsequent to August 13, 2018. Reference to "Predecessor" or "Predecessor Company" relate to the financial position and results of operations of the Company on or prior to August 13, 2018. The Company's consolidated financial statements and related footnotes are presented with a black line division which delineates the lack of comparability between amounts presented after August 13, 2018 and dates prior thereto.

The estimated fair value of Comstock's assets and liabilities and the resulting goodwill at the date of the transaction were as follows:

	(In thousands)

Fair Value of Comstock's common stock	$	149,357

Fair Value of Liabilities Assumed —
Current Liabilities		180,452
Long-Term Debt		2,059,560
Deferred Income Taxes		63,708
Reserve for Future Abandonment Costs		4,440
Net Liabilities Assumed		2,308,160

Fair Value of Assets Acquired —
Current Assets		936,026
Oil and Gas Properties		1,147,749
Other Property & Equipment		4,440
Income Taxes Receivable		19,086
Other Assets		549
Total Assets		2,107,850
Goodwill	$	349,667

The table above represents the preliminary allocation of fair value related to the assets acquired and the liabilities assumed based on the fair value of Comstock. Certain data necessary to complete the fair value allocation is not yet available or is in the process of being finalized, and includes, but is not limited to, final income tax returns. We expect to complete the purchase price allocation during the twelve month period following the Jones Contribution date, during which time the value of the assets and liabilities, including goodwill, may be revised as appropriate.

Goodwill recognized is primarily attributable to the excess of the fair value of Comstock's common stock over the identifiable assets acquired net of liabilities assumed, measured in accordance with generally accepted accounting principles in the United States. The fair value of oil and gas properties, a Level 3 measurement, was determined using discounted cash flow valuation methodology. Key inputs to the valuation included average oil prices of $79.72 per barrel, average natural gas prices of $3.87 per thousand cubic feet and discount factors of 10% - 25%. The combination of the Bakken Shale Properties with Comstock's Haynesville shale properties results in a Company with adequate resources and liquidity to fully exploit its Haynesville/Bossier shale asset base and to continue to expand its opportunity set with future acquisitions and leasing activity in the basin.

Transaction-related costs (i.e., advisory, legal, accounting, valuation, other professional or consulting fees) totaling approximately $2.6 million are not included as a component of consideration transferred but are accounted for as expenses in the predecessor periods in which the costs are incurred and the services received. Costs incurred associated with the issuance of common stock have been accounted for as a reduction of additional paid-in capital.

The successful closing of the Jones Contribution triggered payment of an aggregate of $8.1 million including success fees to financial advisors and certain other fees under our licenses for technical data. These costs were contingent on the consummation of the transactions, all of which were interdependent and all of which had to close in order to meet the legal requirements of the contribution agreement. None of these fees would have been incurred otherwise. The Jones Contribution also caused a change in control, upon which restricted shares granted to employees and directors vested, and performance share units granted to executive officers vested at the maximum number of shares granted. The Company had previously recognized stock-based compensation expense of $7.2 million related to these restricted shares and performance share units. The Company did not recognize an expense for the remaining $11.9 million of unrecognized stock-based compensation expense. The Company's accounting policy for any cost triggered by the consummation of the Jones Contribution was to recognize the cost when the Jones Contribution was consummated. Accordingly, unrecognized stock-based compensation expense has not been recorded in the Consolidated Statement of Operations for the Predecessor period since that statement depicts the results of operations just prior to consummation of the transaction. In addition, since the Successor period reflects the effects of push-down accounting, these costs have also not been recorded as an expense in the Successor period. These costs are being considered in the purchase accounting adjustments in arriving at the fair value of the liabilities assumed since they were incurred only in the event the transactions successfully closed, and they are not clearly identifiable to operations either prior to or subsequent to the Jones Contribution.

Under the terms of the Jones Contribution, April 1, 2018 was the effective date for allocation of revenues and expenses related to net cash of the Bakken Shale Properties, and Comstock will receive $43.2 million related to net cash flow from April 1, 2018 to August 13, 2018 from the Jones Partnerships which has been accounted as part of the Jones Contribution.

These financial statements are presented on the basis of the Bakken Shale Properties being contributed to Comstock in exchange for common stock of Comstock. Comstock is a corporation, which is treated as a taxable C corporation and thus is subject to federal and state income taxes. A deferred tax liability of approximately $77.9 million has been recognized related to the tax basis of the Bakken Shale Properties long-lived assets being less than the book basis in those assets. The recording of this deferred tax liability has been treated as an adjustment to additional paid-in capital in these financial statements. The change in control of Comstock results in a new basis for Comstock as the company is applying pushdown accounting pursuant to ASC 805, Business Combinations. The new basis is pushed down to Comstock for financial reporting purposes, resulting in Comstock's assets, liabilities and equity accounts being recognized at fair value upon the closing of the Jones Contribution. A deferred tax liability, net of valuation allowance, of $52.4 million has been recognized related to the change in the basis for financial reporting purposes as compared to the tax basis of the historical Comstock assets.

The unaudited pro forma financial information presented below sets forth the Company's historical statements of operations for the periods indicated and gives effect to the Jones Contribution and the Company's debt refinancing transactions as if "push down" accounting had been applied as of January 1, 2017. Such information is presented for comparative purposes to the Consolidated Statements of Operations only and does not purport to represent what the Company's results of operations would actually have been had these transactions occurred on the date indicated or to project its results of operations for any future period or date.

Property and Equipment

The Company follows the successful efforts method of accounting for its oil and gas properties. Costs incurred to acquire oil and gas leasehold are capitalized.

On April 27, 2018, Comstock completed the sale of its producing Eagle Ford shale oil and gas properties in McMullen, LaSalle, Frio, Atascosa, Wilson, and Karnes counties, Texas for $125.0 million. The sale was effective November 1, 2017 and the estimated net cash flow from the properties from November 2017 to April 2018 was paid to the buyer at closing. After the sale, the Company had approximately 8,400 net undeveloped acres that are prospective for Eagle Ford shale development. During the predecessor period January 1, 2018 through August 13, 2018, the Company recognized a loss on sale of oil and gas properties of $32.7 million to reduce the carrying value of its assets held for sale to their fair value less costs to sell and to adjust the carrying value of the undeveloped acreage retained to their then fair value of $55.0 million which has been included in proved oil and gas properties. The fair value of the oil and gas properties retained, a Level 3 measurement, was determined using the discounted cash flow valuation methodology applied by Comstock in assessing oil and gas properties for impairment. Key inputs to the valuation included average oil prices of $72.03 per barrel, average natural gas prices of $4.31 per thousand cubic feet and discount factors of 20% - 25%. The Company sold part of the Eagle Ford shale undeveloped acreage in September 2018 for $13.7 million. Also included in the loss on sale for the Predecessor period January 1, 2018 through August 13, 2018 is a loss of $2.7 million resulting from a final settlement for a property sale completed in 2012.

Results of operations for properties that were sold were as follows:

(1)Includes direct operating expenses, depreciation, depletion and amortization and exploration expense and excludes interest and general and administrative expense. No depreciation, depletion and amortization expense has been provided for subsequent to the date the assets were designated as held for sale.

On July 31, 2018, the Company acquired oil and gas properties in North Louisiana and Texas for $39.3 million. These properties consist of approximately 23,000 gross acres (12,000 net) and include 120 (26.2 net) producing natural gas wells, 49 (14.7 net) which produce from the Haynesville shale. All of the acreage acquired is held by production. Comstock has identified 112 (31.0 net) potential drilling locations on this acreage of which 21 (17.9 net) would be operated by Comstock.

On August 14, 2018, in connection with the Jones Contribution, the strategic drilling venture previously entered into by the Company and Arkoma Drilling, LP was terminated and Comstock re-acquired working interests in wells drilled under the joint venture for $17.9 million representing the costs paid by Arkoma Drilling, LP.

The Company assesses the need for an impairment of the capitalized costs for its proved oil and gas properties on a property basis. No impairments were recognized to adjust the carrying value of the Company's proved oil and gas properties during any of the periods presented. Unproved oil and gas properties are also periodically assessed and any impairment in value is charged to expense. The costs of unproved properties are transferred to oil and gas properties and amortized on an equivalent unit-of-production basis as wells are drilled on these properties.

The Company determines the fair values of its oil and gas properties using a discounted cash flow model and proved and risk-adjusted probable oil and natural gas reserves. Undrilled acreage can also be valued based on sales transactions in comparable areas. Significant Level 3 assumptions associated with the calculation of discounted future cash flows included in the cash flow model include management's outlook for oil and natural gas prices, production costs, capital expenditures, and future production as well as estimated proved oil and gas reserves and risk-adjusted probable oil and natural gas reserves. Management's oil and natural gas price outlook is developed based on third-party longer-term price forecasts as of each measurement date. The expected future net cash flows are discounted using an appropriate discount rate in determining a property's fair value.

It is reasonably possible that the Company's estimates of undiscounted future net cash flows attributable to its oil and gas properties may change in the future. The primary factors that may affect estimates of future cash flows include future adjustments, both positive and negative, to proved and appropriate risk-adjusted probable oil and gas reserves, results of future drilling activities, future prices for oil and natural gas, and increases or decreases in production and capital costs. As a result of these changes, there may be future impairments in the carrying values of these or other properties.

Goodwill

Goodwill represents the excess of purchase price over fair value of net tangible and identifiable intangible assets related to the Jones Transactions. The Company is not required to amortize goodwill as a charge to earnings; however, the Company is required to conduct an annual review of goodwill for impairment. The Company will perform its first annual review of goodwill impairment starting on October 1, 2019. The Company has goodwill of $349.7 million as of September 30, 2018 that was recorded in connection with the Jones Contribution.

Derivative Financial Instruments and Hedging Activities

All of the Company's derivative financial instruments are used for risk management purposes and, by policy, none are held for trading or speculative purposes. Comstock minimizes credit risk to counterparties of its derivative financial instruments through formal credit policies, monitoring procedures, and diversification. The Company is not required to provide any credit support to its counterparties other than cross collateralization with the assets securing its bank credit facility. None of the Company's derivative financial instruments involve payment or receipt of premiums. The Company classifies the fair value amounts of derivative financial instruments as net current or noncurrent assets or liabilities, whichever the case may be, by commodity and counterparty.

All of Comstock's natural gas derivative financial instruments are tied to the Henry Hub-NYMEX price index and all of its crude oil derivative financial instruments are tied to the WTI-NYMEX index price. The Company had the following outstanding derivative financial instruments for natural gas price risk management at September 30, 2018:

	Future Production Period

Stock-Based Compensation

Comstock accounts for employee stock-based compensation under the fair value method. Compensation cost is measured at the grant date based on the fair value of the award and is recognized over the award vesting period. The Company recognized $0.3 million of stock-based compensation expense within general and administrative expenses related to awards of restricted stock and performance stock units ("PSUs") to its employees and directors during the Successor period August 14, 2018 through September 30, 2018 and $0.8 million during the predecessor period July 1 through August 13, 2018. For the predecessor periods of the three and nine months ended September 30, 2017, the Company recognized $1.7 million and $4.5 million, respectively, of stock-based compensation expense.

During the period July 1, 2018 through August 13, 2018, the Predecessor Company granted 100,226 shares of restricted stock with a grant date fair value of $0.9 million, or $8.73 per share, to its independent directors. The change of control that occurred due to the Jones Contribution resulting in the vesting of all then outstanding restricted stock grants of 904,181 shares.

During the successor period August 14, 2018 through September 30, 2018, the Company granted 422,545 shares of restricted stock with a grant date fair value of $3.7 million, or $8.70 per share, to its employees. The fair value of each restricted share on the date of grant was equal to its market price. Total unrecognized compensation cost related to unvested restricted stock grants of $3.5 million as of September 30, 2018 is expected to be recognized over a period of 2.9 years.

The change of control that occurred due to the Jones Contribution also resulted in the vesting of all then outstanding performance share units at the maximum amount that could be earned, and a total of 1,028,672 shares of common stock were issued to employees.

During the successor period August 14, 2018 through September 30, 2018, the Company granted 335,545 PSUs with a grant date fair value of $4.3 million, or $12.93 per unit, to its employees, all of which were outstanding as of September 30, 2018. The number of shares of common stock to be issued related to the PSUs is based on the Company's stock price performance as compared to its peers which could result in the issuance of anywhere from zero to 671,090 shares of common stock. Total unrecognized compensation cost related to these grants of $4.2 million as of September 30, 2018 is expected to be recognized over a period of 2.9 years.

Revenue Recognition

On January 1, 2018, the Company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). Comstock adopted this standard using the modified retrospective method of adoption, and it applied the ASU only to contracts that were not completed as of January 1, 2018. Upon adoption, there were no adjustments to the opening balance of equity.

Comstock produces oil and natural gas and reports revenues separately for each of these two primary products in its statements of operations. Revenues are recognized upon the transfer of produced volumes to the Company's customers, who take control of the volumes and receive all the benefits of ownership upon delivery at designated sales points. Payment is reasonably assured upon delivery of production. All sales are subject to contracts that have commercial substance, contain specific pricing terms, and define the enforceable rights and obligations of both parties. These contracts typically provide for cash settlement within 25 days following each production month and are cancellable upon 30 days' notice by either party. Prices for sales of oil and natural gas are generally based upon terms that are common in the oil and gas industry, including index or spot prices, location and quality differentials, as well as market supply and demand conditions. As a result, prices for oil and natural gas routinely fluctuate based on changes in these factors. Each unit of production (barrel of crude oil and thousand cubic feet of natural gas) represents a separate performance obligation under the Company's contracts since each unit has economic benefit on its own and each is priced separately according to the terms of the contracts.

Comstock has elected to exclude all taxes from the measurement of transaction prices, and its revenues are reported net of royalties and exclude revenue interests owned by others because the Company acts as an agent when selling crude oil and natural gas, on behalf of royalty owners and working interest owners. Revenue is recorded in the month of production based on an estimate of the Company's share of volumes produced and prices realized. The Company recognizes any differences between estimates and actual amounts received in the month when payment is received. Historically, differences between estimated revenues and actual revenue received have not been significant. The amount of oil or natural gas sold may differ from the amount to which the Company is entitled based on its revenue interests in the properties. The Company did not have any significant imbalance positions at December 31, 2017 or September 30, 2018. Sales of oil and natural gas generally occur at or near the wellhead. When sales of oil and gas occur at locations other than the wellhead, the Company accounts for costs incurred to transport the production to the delivery point as gathering and transportation expenses. The Company has recognized accounts receivable of $61.0 million as of September 30, 2018 from customers for contracts where performance obligations have been satisfied and an unconditional right to consideration exists.

Income Taxes

Deferred income taxes are provided to reflect the future tax consequences or benefits of differences between the tax basis of assets and liabilities and their reported amounts in the financial statements using enacted tax rates. In recording deferred income tax assets, the Company considers whether it is more likely than not that some portion or all of its deferred income tax assets will be realized in the future. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those deferred income tax assets would be deductible. The Company believes that, after considering all the available objective evidence, historical and prospective, with greater weight given to historical evidence, management is not able to determine that it is more likely than not that all of its deferred tax assets will be realized. As a result, the Company established valuation allowances for its deferred tax assets and U.S. federal and state net operating loss carryforwards that are not expected to be utilized due to the uncertainty of generating taxable income prior to the expiration of the carryforward periods.

The following is an analysis of consolidated income tax provision (benefit):

	Three Months ended September 30,									Nine Months ended September 30,

	$	3,940	$	605			$	(69	)	$	3,940	$	1,065		$	883

The difference between the Company's effective tax rate and the 21% federal statutory rate in effect in 2018 and the 35% rate in effect in 2017 is caused by valuation allowances on deferred taxes and state taxes. The impact of these items varies based upon the Company's projected full year loss and the jurisdictions that are expected to generate the projected losses.

The difference between the federal statutory rate and the effective tax rate is due to the following:

	Three Months ended September 30,										Nine Months ended September 30,
	Transition Period										Transition Period

The Tax Cuts and Jobs Act, which was enacted on December 22, 2017, reduced the corporate income tax rate effective January 1, 2018 from 35% to 21%. Among the other significant tax law changes that potentially affect the Company are the elimination of the corporate alternative minimum tax ("AMT"), changes that require operating losses incurred in 2018 and beyond be carried forward indefinitely with no carryback up to 80% of taxable income in a given year, and limitations on the deduction for interest expense incurred in 2018 or later for amounts in excess of 30% of its adjusted taxable income (defined as taxable income before interest and net operating losses). For tax years beginning before January 1, 2022, the adjusted taxable income for these purposes is also adjusted to exclude the impact of depreciation, depletion and amortization. The Tax Cuts and Jobs Act preserved deductibility of intangible drilling costs for federal income tax purposes, which allows the Company to deduct a portion of drilling costs in the year incurred and minimizes current taxes payable in periods of taxable income. At September 30, 2018, the Company has not completed its accounting for the tax effects of enactment of the Tax Cuts and Jobs Act; however, it has made reasonable estimates of the effects on its existing deferred tax balances. The Company has remeasured certain deferred federal tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. The provisional amount recognized at December 31, 2017 related to the remeasurement of its deferred federal tax balance was $140.4 million, which was subject to a valuation allowance. The Tax Cuts and Jobs Act also repealed the AMT for tax years beginning on or after January 1, 2018 and provides that existing AMT credit carryforwards can be utilized to offset federal taxes for any taxable year. In addition, 50% of any unused AMT credit carryforwards can be refunded during tax years 2018 through 2020. The Company reclassified $19.1 million to a non-current receivable at December 31, 2017 representing the amount of AMT that is now refundable through 2021. The Company is still analyzing certain aspects of the Tax Cuts and Jobs Act, and refining its calculations, which could potentially affect the measurement of those balances or potentially give rise to new deferred tax amounts. Comstock's estimates may also be affected in the future as the Company gains a more thorough understanding of the Tax Cuts and Jobs Act, and how the individual states are implementing this new law.

The shares of common stock issued as a result of the Jones Transaction triggered an ownership change under Section 382 of the Internal Revenue Code. As a result, Comstock's ability to use net operating losses ("NOLs") to reduce taxable income is generally limited to an annual amount based on the fair market value of its stock immediately prior to the ownership change multiplied by the long-term tax-exempt interest rate. The Company's NOLs are estimated to be limited to $3.3 million a year as a result of this limitation. In addition to this limitation, IRC Section 382 provides that a corporation with a net unrealized built-in gain immediately before an ownership change may increase its limitation by the amount of recognized built-in gain recognized during a recognition period, which is generally the five-year period immediately following an ownership change. Based on the fair market value of the Company's common stock immediately prior to the ownership change, Comstock believes that it has a net unrealized built-in gain which will increase the Section 382 limitation during the five-year recognition period.

NOLs that exceed the Section 382 limitation in any year continue to be allowed as carry forwards until they expire and can be used to offset taxable income for years within the carryover period subject to the limitation in each year. NOLs incurred prior to 2018 generally have a 20-year life until they expire. NOLs generated in 2018 and after would be carried forward indefinitely. Comstock's use of new NOLs arising after the date of an ownership change would not be affected by the 382 limitation. If the Company does not generate a sufficient level of taxable income prior to the expiration of the pre-2018 NOL carry forward periods, then it will lose the ability to apply those NOLs as offsets to future taxable income.

The Company's federal income tax returns for the years subsequent to December 31, 2014 remain subject to examination. The Company's income tax returns in major state income tax jurisdictions remain subject to examination for various periods subsequent to December 31, 2012. The Company currently believes that all other significant filing positions are highly certain and that all of its other significant income tax positions and deductions would be sustained under audit or the final resolution would not have a material effect on the consolidated financial statements. Therefore, the Company has not established any significant reserves for uncertain tax positions.

Fair Value Measurements

The Company holds or has held certain financial assets and liabilities that are required to be measured at fair value. These include cash and cash equivalents held in bank accounts and derivative financial instruments in the form of oil and natural gas price swap agreements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level hierarchy is followed for disclosure to show the extent and level of judgment used to estimate fair value measurements:

Level 1 — Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date.

Level 2 — Inputs used to measure fair value, other than quoted prices included in Level 1, are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument.

Level 3 — Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management's estimates of market participant assumptions.

The Company's cash and cash equivalents valuation is based on Level 1 measurements. The Company's oil and natural gas price swap agreements and its natural gas price collars were not traded on a public exchange, and their value is determined utilizing a discounted cash flow model based on inputs that are readily available in public markets and, accordingly, the valuation of these swap agreements, is categorized as a Level 2 measurement. There are no financial assets or liabilities accounted for at fair value as of September 30, 2018 that are a Level 3 measurement.

At September 30, 2018, the Company had a liability of $2.8 million recorded for the fair value of its oil and natural gas swaps and collars. At December 31, 2017, the Company had assets recorded for the fair value of its natural gas price swap agreements of $1.3 million. There were no offsetting swap positions in 2018 or 2017. The change in fair value of these natural gas swaps and collars was recognized as a gain or loss and included as a component of other income (expense).

As of September 30, 2018, the Company's fixed rate debt had a carrying value of $816.3 million and a fair value of $850.0 million. The fair value of the Company's fixed rate debt was based on quoted prices as of September 30, 2018, a Level 2 measurement. The fair value of the floating rate debt outstanding approximated its carrying value, a Level 2 measurement.

Earnings Per Share

Unvested share-based payment awards containing nonforfeitable rights to dividends are considered to be participating securities and included in the computation of basic and diluted earnings per share pursuant to the two-class method. PSUs represent the right to receive a number of shares of the Company's common stock that may range from zero to up to two times the number of PSUs granted on the award date based on the achievement of certain performance measures during a performance period. The number of potentially dilutive shares related to PSUs is based on the number of shares, if any, which would be issuable at the end of the respective period, assuming that date was the end of the contingency period. The treasury stock method is used to measure the dilutive effect of PSUs. The shares that would have been issuable upon exercise of the conversion rights contains in the Predecessor Company's convertible debt for each period are based on the if-converted method for computing potentially dilutive shares of common stock that could be issued upon conversion. None of the Company's participating securities participate in losses and as such are excluded from the computation of basic earnings per share during periods of net losses.

Basic and diluted income (loss) per share were determined as follows:

At September 30, 2018 and December 31, 2017, 422,545 and 619,867 shares of restricted stock, respectively, are included in common stock outstanding as such shares have a nonforfeitable right to participate in any dividends that might be declared and have the right to vote on matters submitted to the Company's stockholders.

Recent Accounting Pronouncements

In January 2017, the FASB issued Accounting Standards Update No. 2017-04 (ASU 2017-04) “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2019 and early adoption is permitted. The Company has initially recognized goodwill in its financial statements for the quarter ended September 30, 2018 and it will assess the impact of ASU 2017-04 on its financial statements when it performs its initial annual impairment assessment.

On January 1, 2018, the Company adopted ASU 2014-09, which supersedes nearly all existing revenue recognition guidance under existing generally accepted accounting principles. This new standard is based upon the principal that revenue is recognized to depict the transfer of 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. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Comstock adopted this standard using the modified retrospective method of adoption and it applied the ASU only to contracts that were not completed as of January 1, 2018. Upon adoption, there were no adjustments to the opening balance of equity and the Company does not expect the standard to have a significant effect on its results of operations, liquidity or financial position.

In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"). ASU 2016-02 requires lessees to include most leases on their balance sheets, but recognize lease costs in their financial statements in a manner similar to accounting for leases prior to ASC 2016-02. ASU 2016-02 is effective for annual periods ending after December 15, 2018 and interim periods thereafter. Early adoption is permitted. The Company has analyzed its major contracts for indications that they contain a lease, and has identified some leases that will need to be reflected as an asset and a liability in its consolidated balance sheet. The Company presently intends to use the modified retrospective method of adoption for this new standard and is evaluating the applicability of the available transition practical expedients as it finalizes its plans for adoption of ASC 2016-02.

The Company utilized the net proceeds from the notes offering, $450.0 million of borrowings under the new bank credit agreement and cash on hand to retire all of its other then-outstanding senior secured and unsecured notes.

The senior notes placement closed on August 3, 2018. Interest on the notes is payable at an annual rate of 9¾% on February 15 and August 15 and the notes mature on August 15, 2026.

The bank credit facility is subject to a borrowing base, which is initially $700.0 million and is re-determined on a semi-annual basis and upon the occurrence of certain other events, and will mature on August 14, 2023. As of September 30, 2018, there were $450.0 million of borrowings outstanding under the revolving credit facility. Borrowings under the bank credit facility are secured by substantially all of the assets of the Company and its subsidiaries. and bear interest at the Company's option, at either LIBOR plus 2.0% to 3.0% or a base rate plus 1.0% to 2.0%, in each case depending on the utilization of the borrowing base. The Company also pays a commitment fee of 0.375% to 0.5% on the unused borrowing base. The bank credit facility places certain restrictions upon the Company's, and its restricted subsidiaries', ability to, among other things, incur additional indebtedness, pay cash dividends, repurchase common stock, make certain loans, investments and divestitures and redeem the new senior notes. The only financial covenants are the maintenance of a leverage ratio of less than 4.0 to 1.0 and a current ratio of at least 1.0 to 1.0 beginning with the three months ended December 31, 2018.
