Basis of Presentation and Summary of Significant Accounting Policies	'
	Note 2 — Basis of Presentation and Summary of Significant Accounting Policies
	Basis of Presentation
	The unaudited condensed consolidated financial statements include Resolute and its subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and Regulation S-X for interim financial reporting. Except as disclosed herein, there has been no material change in our basis of presentation from the information disclosed in the notes to Resolute’s consolidated financial statements for the year ended December 31, 2012. In the opinion of management, all adjustments consisting of normal recurring accruals considered necessary for a fair presentation of the interim financial information have been included. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the full year. All significant intercompany transactions have been eliminated upon consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation.
	In connection with the preparation of the condensed consolidated financial statements, Resolute evaluated subsequent events that occurred after the balance sheet date, through the date of filing.
	Significant Accounting Policies
	The significant accounting policies followed by Resolute are set forth in Resolute’s consolidated financial statements for the year ended December 31, 2012. These unaudited condensed consolidated financial statements are to be read in conjunction with the consolidated financial statements appearing in Resolute’s Annual Report on Form 10-K and related notes for the year ended December 31, 2012.
	Assumptions, Judgments and Estimates
	The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make various assumptions, judgments and estimates to determine the reported amounts of assets, liabilities, revenue and expenses, and in the disclosures of commitments and contingencies. Changes in these assumptions, judgments and estimates will occur as a result of the passage of time and the occurrence of future events. Accordingly, actual results could differ from amounts previously established.
	Significant estimates with regard to the condensed consolidated financial statements include (1) proved oil and gas reserve volumes and the related present value of estimated future net cash flows used in the ceiling test applied to capitalized oil and gas properties; (2) asset retirement obligations; (3) valuation of derivative assets and liabilities; (4) the estimated fair value and allocation of the purchase price related to business combinations; (5) share-based compensation expense; (6) depletion, depreciation and amortization; (7) accrued liabilities; (8) revenue and related receivables and (9) income taxes.
	Oil and Gas Properties
	The Company uses the full cost method of accounting for its oil and gas operations. Accounting rules require Resolute to perform a quarterly “ceiling test” calculation to test its oil and gas properties for possible impairment. The primary components impacting this calculation are commodity prices, reserve quantities added and produced, overall exploration and development costs and depletion expense. If the net capitalized cost of the Company’s oil and gas properties subject to amortization (the “carrying value”) exceeds the ceiling limitation, the excess would be charged to expense. The ceiling limitation is equal to the sum of the present value discounted at 10% of estimated future net cash flows from proved reserves, the cost of properties not being amortized, the lower of cost or estimated fair value of unproven properties included in the costs being amortized, and all related tax effects.
	At September 30, 2013, the calculated value of the ceiling limitation exceeded the carrying value of Resolute’s oil and gas properties subject to the test and no impairment was necessary. However, if there is a negative impact on one or more of the components of the calculation, including market prices of oil and gas, future drilling and capital plans, operating costs or expected production, the Company may incur a full cost ceiling impairment related to its oil and gas properties in future periods.

	New Permian Properties
	On December 21, 2012, the Company purchased properties in Denton Field on the Northwest Shelf in Lea County, New Mexico, and in the Spraberry trend in the Midland Basin portion of the Permian Basin in Howard County, Texas, for a purchase price of approximately $117 million. Additionally, on December 28, 2012, the Company purchased properties in the Wolfberry play in the Midland Basin portion of the Permian Basin in Midland and Ector counties, Texas, for a purchase price of approximately $133 million. Concurrently with the latter transaction, the Company acquired, for additional consideration of $6.0 million, the option to buy the balance of the working interest in and operatorship of the properties under substantially the same terms as the initial transaction (the “Option Properties”). On March 22, 2013, the Company exercised the option and acquired the Option Properties for $258 million, net of the option fee after customary purchase price adjustments, which were estimated at closing. Revenue and expenses related to the Option Properties are included in the condensed consolidated statements of operations beginning March 22, 2013, the closing date of the transaction. The properties acquired under the December and March acquisitions are referred to as the “New Permian Properties.” Together, the December and March acquisitions, which the Company refers to as the “Permian Acquisitions,” were accounted for using the acquisition method.
	The preliminary purchase price of the New Permian Properties was comprised of the following (in thousands):
		September 2013			December 2012
	Purchase price	$	258,000		$	250,000
	The Company has not completed its assessment of the fair values of the assets acquired and liabilities assumed, but intends to do so within twelve months of the purchase date. Accordingly, the following table presents the preliminary purchase price allocation of the New Permian Properties at September 30, 2013, and December 31, 2012, based on the fair values of assets acquired and liabilities assumed (in thousands):
		September 30, 2013			December 31, 2012

	Unproved oil and gas properties		137,000			122,000
	Asset retirement obligations assumed		—			(3,000	)
	Total purchase price	$	258,000		$	250,000
	Pro Forma Financial Information
	The unaudited pro forma consolidated financial information in the table below summarizes the results of operations of the Company as though the purchase of the Option Properties in March 2013 had occurred on January 1, 2012, and the purchase of the properties in the Permian Basin in December 2012 had occurred on January 1, 2012. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the Permian Acquisitions had taken place at the beginning of the earliest periods presented or that may result in the future. The pro forma adjustments made utilize certain assumptions that Resolute believes are reasonable based on the available information.
	The unaudited pro forma financial information for the three and nine months ended September 30, 2013 and 2012 combine the historical results of the New Permian Properties and Resolute (in thousands, except per share amounts):

	Aneth Field Transactions
	During the second quarter of 2012 Resolute and Navajo Nation Oil and Gas Company (“NNOGC”) entered into two transactions regarding the Aneth Field Properties.
	In the first transaction, effective January 1, 2012, Resolute and NNOGC together, on a 50%/50% basis, acquired from affiliates of Denbury Resources Inc. (“Denbury”) a 13% working interest in the Aneth Unit and an 11% working interest in the Ratherford Unit for a total cash consideration of $75 million. The acquisition from Denbury was accounted for using the acquisition method. After closing adjustments, the $37.7 million net purchase price was allocated to proved oil and gas properties. Revenue and expenses associated with the acquired interests are included in the consolidated statements of income concurrent with the closing of the transaction in April 2012.
	Contemporaneously with this transaction, Resolute and NNOGC also entered into an amendment to their Cooperative Agreement. Among other changes, this amendment allowed NNOGC to exercise options to purchase 10% of the Company’s interest in the Aneth Field Properties, as they existed before giving effect to the Denbury transaction discussed above. These options were exercised for cash consideration of $100 million. Resolute entered into a purchase and sale agreement relating to the exercise of the options which provided that the transaction be closed and paid for in two equal transfers, each for 5% of Resolute’s interest in the properties. The first transfer took place in July 2012 and the second transfer took place in January 2013, each with an effective date of January 1, 2012.
	Sale of New Home Properties
	On June 27, 2013, the Company entered into a purchase and sale agreement with HRC Energy, LLC, a Colorado limited liability company, and a wholly-owned subsidiary of Halcón Resources Corporation, a Delaware corporation, effective March 1, 2013, to dispose of certain Bakken properties located in Williams County, North Dakota (the “New Home Properties”) for proceeds of $75 million before customary purchase price adjustments. The transaction closed on July 15, 2013 and net proceeds received were recorded as a reduction to the capitalized costs of the Company’s oil and gas properties.

Earnings per Share	'
	Note 4 — Earnings per Share
	The Company computes basic net income (loss) per share using the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of shares of common stock and, if dilutive, potential shares of common stock outstanding during the period. Potentially dilutive shares consist of the incremental shares issuable under the outstanding warrants, which entitle the holder to purchase one share of the Company’s common stock at a price of $13.00 per share and which expire on September 25, 2014, and incremental shares issuable under the Company’s 2009 Performance Incentive Plan (the “Incentive Plan”). The treasury stock method is used to measure the dilutive impact of potentially dilutive shares.

	Credit Facility
	Resolute’s credit facility is with a syndicate of banks led by Wells Fargo Bank, National Association (the “Credit Facility”) with Resolute as the borrower. The Credit Facility specifies a maximum borrowing base as determined by the lenders. The determination of the borrowing base takes into consideration the estimated value of Resolute’s oil and gas properties in accordance with the lenders’ customary practices for oil and gas loans. The borrowing base is redetermined semi-annually, and the amount available for borrowing could be increased or decreased as a result of such redeterminations. Under certain circumstances, either Resolute or the lenders may request an interim redetermination.
	In March 2013, and in connection with the purchase of the Option Properties, the Company entered into the Sixth Amendment to the amended and restated Credit Facility agreement, resulting in a borrowing base increase to $485 million, consisting of a $445 million conforming tranche (which expires on March 22, 2018) and a $40 million non-conforming tranche. The Sixth Amendment, among other things, also amended the Maximum Leverage Ratio to (a) 4.50:1.00 for all fiscal quarters ending through December 31, 2013, (b) 4.25:1.00 for the fiscal quarter ending March 31, 2014, and (c) 4.00:1.00 for all fiscal quarters ending June 30, 2014, and thereafter. In addition, the maturity date of the revolving Credit Facility was extended from April 2017 to March 2018. In April 2013, the Company entered into the Seventh Amendment to the amended and restated Credit Facility which adjusted the Maximum Leverage Ratio to (a) 4.25:1:00 for the fiscal year quarter ending December 31, 2012, (b) 4.85:1:00 for the fiscal quarter ending March 31, 2013, (c) 4.50:1.00 for all fiscal quarters ending June 30, 2013 through December 31, 2013, (d) 4.25:1.00 for the fiscal quarter ending March 31, 2014, and (e) 4.00:1.00 for all fiscal quarters ending June 30, 2014 and thereafter. Each base rate borrowing under the Credit Facility accrues interest at either (a) the London Interbank Offered Rate, plus a margin which varies from 1.50% to 2.50% (or 3.0% if the Company utilizes any portion of the non-conforming tranche) or (b) the alternative Base Rate defined as the greater of (i) the Administrative Agent’s Prime Rate (ii) the Federal Funds effective Rate plus 0.5% or (iii) an adjusted London Interbank Rate plus a margin which ranges from 0.50% to 1.50% (or 2.0% if the Company utilizes any portion of the non-conforming tranche). Each such margin is based on the level of utilization under the borrowing base. In connection with the equity offering that closed in May 2013, the $40 million non-conforming tranche of the borrowing base was automatically terminated, resulting in a borrowing base decrease to $445 million. In July 2013, the Credit Facility borrowing base was further reduced by $30 million, to $415 million, as a result of the disposition of the New Home Properties.
	As of September 30, 2013, outstanding borrowings were $285 million under the borrowing base of $415 million. The borrowing base availability had been reduced by $3.1 million in conjunction with letters of credit issued to vendors at September 30, 2013, and other limitations based upon a multiple of trailing earnings as defined in the Credit Facility. To the extent that the borrowing base, as adjusted from time to time, exceeds the outstanding balance, no repayments of principal are required prior to maturity. The Credit Facility is guaranteed by all of Resolute’s subsidiaries and is collateralized by substantially all of the proved oil and gas assets of Resolute Aneth, LLC, Resolute Wyoming, Inc. and Resolute Natural Resources Southwest, LLC, which are wholly-owned subsidiaries of the Company.
	As of September 30, 2013, the weighted average interest rate on the outstanding balance under the Credit Facility was 2.18%. The recorded value of the Credit Facility approximates its fair market value because the interest rate of the Credit Facility is variable over the term of the loan (Level 2 fair value measurement).
	The Credit Facility includes terms and covenants that place limitations on certain types of activities, the payment of dividends, and require satisfaction of certain financial tests. Resolute was in compliance with all terms and covenants of the Credit Facility at September 30, 2013.
	Resolute Energy Corporation, the stand-alone parent entity, has insignificant independent assets and no operations. There are no restrictions on the Company’s ability to obtain cash dividends or other distributions of funds from its subsidiaries, except those imposed by applicable law.
	Senior Notes
	In April 2012, the Company consummated a private placement of senior notes with a principal amount of $250 million, and in December 2012 placed a follow-on issuance of senior notes with a principal amount of $150 million (the “Senior Notes” or the “Notes”). The Senior Notes are due May 1, 2020 and bear an annual interest rate of 8.50% with the interest on the Notes payable semiannually in cash on May 1 and November 1 of each year.
	The Senior Notes were issued under an Indenture (the “Indenture”) among the Company, the Company’s existing subsidiaries (the “Guarantors”) and U.S. Bank National Association, as trustee (the “Trustee”) in a private transaction not subject to the registration requirements of the Securities Act of 1933. In March 2013, the Company registered the Senior Notes with the Securities and Exchange Commission by filing an amendment to the registration statement on Form S-4 enabling holders of the Senior Notes to exchange the privately placed Notes for publically registered Notes with substantially identical terms. The Indenture contains affirmative and negative covenants that, among other things, limit the Company’s and the Guarantors’ ability to make investments, incur additional indebtedness or issue preferred stock, create liens, sell assets, enter into agreements that restrict dividends or other payments by restricted subsidiaries, consolidate, merge or transfer all or substantially all of the assets of the Company, engage in transactions with the Company’s affiliates, pay dividends or make other distributions on capital stock or prepay subordinated indebtedness and create unrestricted subsidiaries. The Indenture also contains customary events of default. Upon occurrence of events of default arising from certain events of bankruptcy or insolvency, the Senior Notes shall become due and payable immediately without any declaration or other act of the Trustee or the holders of the Senior Notes. Upon the occurrence of certain other events of default, the Trustee or the holders of the Senior Notes may declare all outstanding Senior Notes to be due and payable immediately. The Company was in compliance with all financial covenants under its Senior Notes as of September 30, 2013.
	The Senior Notes are general unsecured senior obligations of the Company and guaranteed on a senior unsecured basis by the Guarantors. The Senior Notes rank equally in right of payment with all existing and future senior indebtedness of the Company, will be subordinated in right of payment to all existing and future senior secured indebtedness of the Guarantors, will rank senior in right of payment to any future subordinated indebtedness of the Company and will be fully and unconditionally guaranteed by the Guarantors on a senior basis.
	The Senior Notes are redeemable by the Company on or after May 1, 2016, on not less than 30 or more than 60 days’ prior notice, at redemption prices set forth in the Indenture. In addition, at any time prior to May 1, 2015, the Company may use the net proceeds from equity offerings and warrant exercises to redeem up to 35% of the principal amount of Notes issued under the Indenture at a redemption price equal to 108.50% of the principal amount of the Notes redeemed, plus accrued and unpaid interest. The Senior Notes may also be redeemed at any time prior to May 1, 2016, at the option of the Company at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the applicable premium, and accrued and unpaid interest and additional interest, if any, to the applicable redemption date as set forth in the Indenture. If a change of control occurs, each holder of the Notes will have the right to require that the Company purchase all of such holder’s Notes in an amount equal to 101% of the principal of such Notes, plus accrued and unpaid interest, if any, to the date of the purchase.
	The fair value of the Senior Notes at September 30, 2013 was estimated to be $413 million based upon data from independent market makers (Level 2 fair value measurement).
	For the three months ended September 30, 2013 and 2012, the Company incurred interest expense on long-term debt of $6.8 million and $4.6 million, respectively. For the nine months ended September 30, 2013 and 2012, the Company incurred interest expense on long-term debt of $22.0 million and $9.5 million, respectively. The Company capitalized $4.3 million and $1.5 million of interest expense during the quarters ended September 30, 2013 and 2012, respectively. The Company capitalized $11.7 million and $3.3 million of interest expense during the nine months ended September 30, 2013 and 2012, respectively.

	Preferred Stock
	The Company is authorized to issue up to 1,000,000 shares of preferred stock, par value $0.0001 with such designations, voting and other rights and preferences as may be determined from time to time by the Board of Directors. No shares were issued and outstanding as of September 30, 2013 or December 31, 2012.
	Common Stock
	The authorized common stock of the Company consists of 225,000,000 shares. The holders of the common shares are entitled to one vote for each share of common stock. In addition, the holders of the common stock are entitled to receive dividends when, as and if declared by the Board of Directors. At September 30, 2013 and December 31, 2012, the Company had 76,756,967 and 61,872,694 shares of common stock issued and outstanding, respectively.
	During the second quarter of 2013, the Company issued 13.3 million shares of common stock in a public offering at $8.00 per share for net proceeds of $101.8 million, after underwriting discounts and commissions. The net proceeds were used to repay outstanding borrowings under the Credit Facility.
	During the nine months ended September 30, 2013, no warrants were repurchased. During the second quarter of 2012, the Company repurchased 9,634,821 warrants for aggregate consideration of approximately $10.0 million in a private transaction at an average price of $1.04 per warrant. During the nine months ended September 30, 2013 and 2012, no warrants were exercised. At September 30, 2013, 33,040,682 warrants remain outstanding.
	Share-Based Compensation
	The Company accounts for share-based compensation in accordance with FASB ASC Topic 718, Stock Compensation.
	On July 31, 2009, the Company adopted the Incentive Plan, providing for long-term share-based awards intended as a means for the Company to attract, motivate, retain and reward directors, officers, employees and other eligible persons through the grant of awards and incentives for high levels of individual performance and improved financial performance of the Company. The share-based awards are also intended to further align the interests of award recipients and the Company’s stockholders. The maximum number of shares of common stock that may be issued under the Incentive Plan is 9,157,744.
	Time-Based Awards
	Shares of time-based restricted stock generally vest in three or four year increments at specified dates based on continued employment. The compensation expense to be recognized for the time-based awards was measured based on the Company’s closing stock price on the dates of grant, utilizing estimated forfeiture rates between 0% and 10% which are updated periodically based on actual employee turnover. During the nine months ended September 30, 2013, the Company granted 1,534,988 time-based shares of restricted stock to employees and directors, pursuant to the Incentive Plan.
	The following table summarizes the changes in non-vested time-based awards for the nine month period ended September 30, 2013:
		Shares			Weighted
					Average
					Grant Date
					Fair Value
	Non-vested, beginning of period		1,176,890		$	12
	Granted		1,534,988			10.33
	Vested		(88,760	)		12
	Forfeited		(161,988	)		11.25
	Non-vested, end of period		2,461,130		$	11.01
	For the three months ended September 30, 2013 and 2012, the Company recorded $2.7 million and $2.2 million of share-based compensation expense related to time-based awards, net of amounts billed to partners, respectively. For the nine months ended September 30, 2013 and 2012, the Company recorded $7.8 million and $5.3 million of share-based compensation expense related to time-based awards, net of amounts billed to partners, respectively. There was unrecognized compensation expense of approximately $19.1 million at September 30, 2013, which is expected to be recognized over a weighted-average period of 2.1 years.
	Performance-Based Awards
	For grants made through year-end 2012, performance-based shares generally vest in equal tranches beginning on December 31 of the year of the grant if there has been a 10% annual appreciation in the trading price of the Company’s common stock, compounded annually, from the twenty trading day average stock price ended on December 31 of the year prior to the grant (which was $11.134 for 2010 grants, $14.227 for 2011 grants and $11.639 for 2012 grants). At the end of each year, the twenty trading day average stock price will be measured, and if the 10% threshold is met, the stock subject to the performance criteria will vest. If the 10% threshold is not met, shares that have not vested will be carried forward to the following year subject to a four year maximum vesting period. These awards are referred to as “Stock Appreciation Awards.”
	In March 2013, the Compensation Committee awarded 354,517 performance-based restricted shares to executive officers of the Company under the Incentive Plan. The restricted stock grants vest only upon achievement of thresholds of cumulative total shareholder return (“TSR”) as compared to a specified peer group (the “Performance-Vested Shares”). A TSR percentile (the “TSR Percentile”) is calculated based on the change in the value of the Company’s common stock between the grant date and the applicable vesting date, including any dividends paid during the period, as compared to the respective TSRs of a specified group of 17 peer companies. The Performance-Vested Shares vest in three installments to the extent that the applicable TSR Percentile ranking thresholds are met upon the one-, two- and three-year anniversaries of the grant date. Performance-Vested Shares that are eligible to vest on a vesting date but do not qualify for vesting become eligible for vesting again on the next vesting date. All Performance-Vested Shares that do not vest as of the final vesting date will be forfeited on such date.
	In March 2013, the Compensation Committee also granted rights to earn additional shares of common stock upon achievement of a higher TSR Percentile (“Outperformance Shares”). The Outperformance Shares are earned in increasing increments based on a TSR Percentile attained over a specified threshold. Outperformance Shares may be earned on any vesting date to the extent that the applicable TSR Percentile ranking thresholds are met in three installments on the one-, two- and three-year anniversaries of the grant date. Outperformance Shares that are earned at a vesting date will be issued to the recipient; however, prior to such issuance, the recipient is not entitled to stockholder rights with respect to Outperformance Shares. Outperformance Shares that are eligible to be earned but remain unearned on a vesting date become eligible to be earned again on the next vesting date. The right to earn any theretofore unearned Outperformance Shares terminates immediately following the final vesting date. The Performance-Vested Shares and the Outperformance Shares are referred to as the “TSR Awards.”
	The compensation expense to be recognized for the TSR Awards and Stock Appreciation Awards was measured based on the estimated fair value at the date of grant using a Monte Carlo simulation model and utilize estimated forfeiture rates between 4% and 15% which are updated periodically based on actual employee turnover.
	The valuation model for the TSR Awards used the following assumptions:
	Grant Year	Average Expected Volatility		Expected Dividend Yield	Risk-Free Interest Rate
	2013	35.00%		0%	0.42%
	Share-based compensation expense related to the TSR Awards and the Stock Appreciation Awards for the three months ended September 30, 2013 and 2012, was $0.7 million and $0.6 million, respectively. Share-based compensation expense related to the TSR Awards and Stock Appreciation Awards for the nine months ended September 30, 2013 and 2012, was $2.7 million and $1.6 million, respectively. There was unrecognized compensation expense for TSR and Stock Appreciation Awards of approximately $3.2 million and $0.5 million at September 30, 2013, which is expected to be recognized over a weighted-average period of 2.4 and 1.1 years, respectively. The following table summarizes changes in non-vested Performance-Based Awards for the nine month period ended September 30, 2013:

Derivative Instruments	'
	Note 9 — Derivative Instruments
	Resolute enters into commodity derivative contracts to manage its exposure to oil and gas price volatility. Resolute has not elected to designate derivative instruments as hedges under the provisions of FASB ASC Topic 815, Derivatives and Hedging. As a result, these derivative instruments are marked to market at the end of each reporting period and changes in the fair value are recorded in the accompanying consolidated statements of operations. Gains and losses on commodity derivative instruments from Resolute’s price risk management activities are recognized in other income (expense). The cash flows from derivatives are reported as cash flows from operating activities unless the derivative contract is deemed to contain a financing element. Derivatives deemed to contain a financing element are reported as financing activities in the condensed consolidated statement of cash flows.
	The Company utilizes fixed price swaps, basis swaps, option contracts and two-and three-way collars. These instruments generally entitle Resolute (the floating price payer in most cases) to receive settlement from the counterparty (the fixed price payer in most cases) for each calculation period in amounts, if any, by which the settlement price for the scheduled trading days applicable to each calculation period is less than the fixed strike price or floor price. The Company would pay the counterparty if the settlement price for the scheduled trading days applicable to each calculation period exceeds the fixed strike price or ceiling price. The amount payable by Resolute, if the floating price is above the fixed or ceiling price, is the product of the notional contract quantity and the excess of the floating price over the fixed or ceiling price per calculation period. The amount payable by the counterparty, if the floating price is below the fixed or floor price, is the product of the notional contract quantity and the excess of the fixed or floor price over the floating price per calculation period. A three-way collar consists of a two-way collar contract combined with a put option contract sold by the Company with a strike price below the floor price of the two-way collar. The Company receives price protection at the purchased put option floor price of the two-way collar if commodity prices are above the sold put option strike price. If commodity prices fall below the sold put option strike price, the Company receives the cash market price plus the variance between the two put option strike prices. This type of instrument captures more value in a rising commodity price environment, but limits the benefits in a downward commodity price environment. Basis swaps are used in connection with gas swaps in order to fix the price differential between the NYMEX Henry Hub price and the index price at which the gas production is sold.
	During the third quarter of 2013, the Company paid $10.7 million to restructure or terminate certain 2013 derivative contracts. As of September 30, 2013, the fair value of the Company’s commodity derivatives was a net liability of $11.9 million.

	Credit Risk and Contingent Features in Derivative Instruments
	Resolute is exposed to credit risk to the extent of nonperformance by the counterparties in the derivative contracts discussed above. All counterparties are lenders under Resolute’s Credit Facility. Accordingly, Resolute is not required to provide any credit support to its counterparties other than cross collateralization with the properties securing the Credit Facility. Resolute’s derivative contracts are documented with industry standard contracts known as a Schedule to the Master Agreement and International Swaps and Derivative Association, Inc. Master Agreement (“ISDA”). Typical terms for each ISDA include credit support requirements, cross default provisions, termination events, and set-off provisions. Resolute has set-off provisions with its lenders that, in the event of counterparty default, allow Resolute to set-off amounts owed under the Credit Facility or other general obligations against amounts owed for derivative contract liabilities.
	Resolute does not offset the fair value amounts of derivative assets and liabilities with the same counterparty for financial reporting purposes.

Basis of Presentation	'
	Basis of Presentation
	The unaudited condensed consolidated financial statements include Resolute and its subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and Regulation S-X for interim financial reporting. Except as disclosed herein, there has been no material change in our basis of presentation from the information disclosed in the notes to Resolute’s consolidated financial statements for the year ended December 31, 2012. In the opinion of management, all adjustments consisting of normal recurring accruals considered necessary for a fair presentation of the interim financial information have been included. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the full year. All significant intercompany transactions have been eliminated upon consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation.
	In connection with the preparation of the condensed consolidated financial statements, Resolute evaluated subsequent events that occurred after the balance sheet date, through the date of filing.
Significant Accounting Policies	'
	Significant Accounting Policies
	The significant accounting policies followed by Resolute are set forth in Resolute’s consolidated financial statements for the year ended December 31, 2012. These unaudited condensed consolidated financial statements are to be read in conjunction with the consolidated financial statements appearing in Resolute’s Annual Report on Form 10-K and related notes for the year ended December 31, 2012.
Assumptions, Judgments and Estimates	'
	Assumptions, Judgments and Estimates
	The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make various assumptions, judgments and estimates to determine the reported amounts of assets, liabilities, revenue and expenses, and in the disclosures of commitments and contingencies. Changes in these assumptions, judgments and estimates will occur as a result of the passage of time and the occurrence of future events. Accordingly, actual results could differ from amounts previously established.
	Significant estimates with regard to the condensed consolidated financial statements include (1) proved oil and gas reserve volumes and the related present value of estimated future net cash flows used in the ceiling test applied to capitalized oil and gas properties; (2) asset retirement obligations; (3) valuation of derivative assets and liabilities; (4) the estimated fair value and allocation of the purchase price related to business combinations; (5) share-based compensation expense; (6) depletion, depreciation and amortization; (7) accrued liabilities; (8) revenue and related receivables and (9) income taxes.
Oil and Gas Properties	'
	Oil and Gas Properties
	The Company uses the full cost method of accounting for its oil and gas operations. Accounting rules require Resolute to perform a quarterly “ceiling test” calculation to test its oil and gas properties for possible impairment. The primary components impacting this calculation are commodity prices, reserve quantities added and produced, overall exploration and development costs and depletion expense. If the net capitalized cost of the Company’s oil and gas properties subject to amortization (the “carrying value”) exceeds the ceiling limitation, the excess would be charged to expense. The ceiling limitation is equal to the sum of the present value discounted at 10% of estimated future net cash flows from proved reserves, the cost of properties not being amortized, the lower of cost or estimated fair value of unproven properties included in the costs being amortized, and all related tax effects.
	At September 30, 2013, the calculated value of the ceiling limitation exceeded the carrying value of Resolute’s oil and gas properties subject to the test and no impairment was necessary. However, if there is a negative impact on one or more of the components of the calculation, including market prices of oil and gas, future drilling and capital plans, operating costs or expected production, the Company may incur a full cost ceiling impairment related to its oil and gas properties in future periods.
