NOTE 1 - NATURE OF OPERATIONS AND BASIS OF PRESENTATION

PDC Energy, Inc. (the("PDC", the "Company," "we," "us," or "our") is a domestic independent exploration and production company that produces, develops, acquires and explores for crude oil, natural gas, and NGLs, with primary operations in the Wattenberg Field in Colorado and, beginning in December 2016, the Delaware Basin in Reeves and Culberson Counties, Texas. We also have operations in the Utica Shale in southeasternSoutheastern Ohio. Subsequent to June 30, 2017, as part of plans to divest the Utica Shale properties, we engaged an investment banking group to assist in marketing them for sale; therefore, these properties will be classified as held-for-sale upon meeting the criteria for such classification in the third quarter of 2017. Our operations in the Wattenberg Field are focused in the horizontal Niobrara and Codell plays and our OhioDelaware Basin operations are currently focused in the Utica Shale play. In addition, we currently have a pending acquisition in the Delaware Basin in Texas. See Note 6, Pending Acquisition.Wolfcamp zones. As of SeptemberJune 30, 2016,2017, we owned an interest in approximately 3,0002,900 gross productive wells. We are engaged in two businessoperating segments: Oilour oil and Gas Explorationgas exploration and Productionproduction segment and Gas Marketing.our gas marketing segment. Beginning in 2017, our gas marketing segment does not meet the quantitative thresholds to require disclosure as a separate reportable segment. All of our material operations are attributable to our exploration and production business; therefore, all of our operations are presented as a single segment for all periods presented.

The accompanying unaudited condensed consolidated financial statements include the accounts of PDC, our wholly-owned subsidiary Riley Natural Gas ("RNG")subsidiaries, and our proportionate share of our fourtwo affiliated partnerships. Pursuant to the proportionate consolidation method, our accompanying condensed consolidated financial statements include our pro rata share of assets, liabilities, revenues and expenses of the entities which we proportionately consolidate. All material intercompany accounts and transactions have been eliminated in consolidation.

In our opinion, the accompanying condensed consolidated financial statements contain all adjustments, (consistingconsisting of only normal recurring adjustments)adjustments, necessary for a fair statement of our financial statements for interim periods in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, pursuant to such rules and regulations, certain notes and other financial information included in audited financial statements have been condensed or omitted. The December 31, 20152016 condensed consolidated balance sheet data was derived from audited statements, but does not include all disclosures required by U.S. GAAP. The information presented in this Quarterly Report on Form 10-Q should be read in conjunction with our audited consolidated financial statements and notes thereto included in our 20152016 Form 10-K. Our results of operations and cash flows for the three and ninesix months ended SeptemberJune 30, 20162017 are not necessarily indicative of the results to be expected for the full year or any other future period.

Certain immaterial reclassifications have been made to our prior period statement of operations to conform to the current period presentation. The reclassifications had no impact on previously reported cash flows, net earnings, earnings per share or stockholders' equity.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board ("FASB")FASB and the International Accounting Standards Board issued their converged standard on revenue recognition that provides a single, comprehensive model that entities will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The standard outlines a five-step approach to apply the underlying principle: (1) identify the contract with the customer, (2) identify the separate performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to separate performance obligations, and (5) recognize revenue when (or as)or as each performance obligation is satisfied. In March 2016, the FASB issued an update to the standard intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations when recognizing revenue. In December 2016, the FASB issued technical corrections and improvements to the standard. The revenue standard is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The revenue standard can be adopted under the full retrospective method or simplified transition method. Entities are permitted to adopt the revenue standard early, beginning with annual reporting periods after December 15, 2016. We are currently evaluatingin the impact these changes may haveprocess of assessing potential impacts of the new standard on our condensed consolidated financial statements.existing revenue recognition criteria, as well as on related revenue recognition disclosures.

In August 2014, the FASB issued a new standard related to the disclosure of uncertainties about an entity's ability to continue as a going concern. The new standard requires management to assess an entity's ability to continue as a going concern at the end of every reporting period and to provide related footnote disclosures in certain circumstances. The new standard will be effective for all entities in the first annual period ending after December 15, 2016, with early adoption permitted. We expect to adopt this standard in the fourth quarter of 2016. Adoption of this standard is not expected to have a significant impact on our condensed consolidated financial statements.

In February 2016, the FASB issued an accounting update aimed at increasing the transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about related leasing arrangements. For leases with terms of more than 12 months, the accounting update requires lessees to recognize ana right-of-use asset and lease liability for its right to use the underlying asset and a lease liability for the corresponding lease obligation. Both the lease asset and liability will initially be measured at the present value of the future minimum lease payments over the lease term. Subsequent measurement, including the presentation of expenses and cash flows, will depend upon the classification of the lease as either a finance or operating lease. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted, and is to be applied as of the beginning of the earliest period presented using a modified retrospective approach. We are currently evaluatingin the process of assessing the impact these changes may have on our condensed consolidated financial statements.

In March 2016, the FASB issued an accounting update on stock-based compensation intended to simplify several aspects of the accounting for employee share-based payment award transactions. Areas of simplification include income tax consequences, classification of the awards as either equity or liabilities and the classification on the statement of cash flows. The guidance is effective for fiscal years beginning

after December 15, 2016, and interim periods within those years, with early adoption permitted. We expect to adopt this standard in the fourth quarter of 2016. Adoption of this standard is not expected to have a significant impact on our condensed consolidated financial statements.

In August 2016, the FASB issued an accounting update on statements of cash flows to address diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the impact these changes may have on our consolidated financial statements.

In November 2016, the FASB issued an accounting update on statements of cash flows to address diversity in practice in the classification and presentation of changes in restricted cash. The accounting update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling beginning-of-period and end-of-period amounts shown on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the impact these changes may have on our consolidated financial statements.

In January 2017, the FASB issued an accounting update to simplify the subsequent measurement of goodwill. The update eliminates the two-step process that required identification of potential impairment and a separate measure of actual impairment. The annual and/or interim assessments are still required to be completed. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. We elected to early adopt this standard in the second quarter of 2017 and will implement the new guidance accordingly in performing impairment testing in 2017. Our annual evaluation of goodwill for impairment is expected to occur in the fourth quarter of 2017, at which time we will apply this accounting update and the impact can be determined.

In May 2017, the FASB issued an accounting update clarifying when to account for a change to the terms or conditions of a share-based payment award as a modification. The guidance is effective for fiscal years beginning on or after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. Adoption of this standard is not expected to have a significant impact on our condensed consolidated financial statements.

NOTE 3 - FAIR VALUE OF FINANCIAL INSTRUMENTSBUSINESS COMBINATION

DeterminationDelaware Basin Acquisition. On December 6, 2016, we closed on an acquisition which has been accounted for as a business combination. The transaction was for the purchase of Fair Value

Ourapproximately 57,900 net acres, approximately 30 completed and producing wells and related midstream infrastructure in Reeves and Culberson Counties, Texas, for an aggregate consideration to the sellers of approximately $1.64 billion, after preliminary post-closing adjustments, comprised of approximately $946.0 million in cash, including the payment of $40.0 million of debt of the seller at closing and other purchase price adjustments, and 9.4 million shares of our common stock valued at approximately $690.7 million at the time the acquisition closed. The estimated fair value measurementsof assets acquired and liabilities assumed in the acquisition presented below are estimated pursuantpreliminary and subject to a fair value hierarchy that requires us to maximizecustomary additional post-closing adjustments as more detailed analysis associated with the useacquired properties is completed. The final settlement statement has been agreed upon with the sellers; however, we are in the process of observable inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date, giving the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in different levels offinalizing the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability, and may affect the valuationvalues of the assets acquired and liabilities assumed and their placement withinexpect to keep the fair value hierarchy levels.transaction open through the third quarter of 2017 to ensure that any final allocation adjustments associated with the period through final settlement are appropriately reflected in the final purchase price allocation. The three levels of inputs that maymost significant item to be used to measure fair value are defined as:

Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable forcompleted is the asset or liability, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived from observable market data by correlation or other means.

Level 3 – Unobservable inputs for the asset or liability, including situations where there is little, if any, market activity.

Derivative Financial Instruments

We measure the fair value of our derivative instruments based upon a pricing model that utilizes market-based inputs, including, but not limited to, the contractual priceallocation of the underlying position, current market prices, crude oilper acre values across the acquisition. There were a significant number of leases acquired with complex lease terms and natural gas forward curves, discount rates such as the LIBOR curve for a similar duration of each outstanding position, volatility factors and nonperformance risk. Nonperformance risk considers the effect of our credit standing on the fair value of derivative liabilities and the effect of our counterparties' credit standings on the fair value of derivative assets. Both inputs to the model are based on published credit default swap rates and the duration of each outstanding derivative position.

We validate our fair value measurement through the review of counterparty statements and other supporting documentation, the determination that the source of the inputs is valid, the corroboration of the original source of inputs through access to multiple quotes, if available, or other information and monitoring changes in valuation methods and assumptions. While we use common industry practices to develop our valuation techniques and believe our valuation method is appropriate and consistent with those used by other market participants, changes in our pricing methodologies or the underlying assumptions could result in significantly different fair values.

The significant unobservable input used indetails of the fair value measurementestimated purchase price and the preliminary allocation of our derivative contracts is the implied volatility curve,purchase price for the transaction, which is provided by a third-party vendor. A significant increase or decrease in the implied volatility, in isolation, would have a directionally similar effect resulting in a significantly higher or lower fair value measurement of our Level 3 derivative contracts.

The carrying value of the financial instruments included in current assets and current liabilities approximate fair value due tomeasurements of assets acquired and liabilities assumed are based on inputs that are not observable in the short-term maturitiesmarket, and therefore represent Level 3 inputs. The fair values of these instruments.

We utilize fair value on a nonrecurring basis to review our crude oil and natural gas properties for possible impairment when events and circumstances indicateasset retirement obligations were measured using valuation techniques that convert future cash flows to a possible decline insingle discounted amount. Significant inputs to the recoverabilityvaluation of the carrying value of such properties. The fair value of the properties is determined based upon estimated future discounted cash flow, a Level 3 input, using estimated production and prices at which we reasonably expect the crude oil and natural gas properties include estimates of reserves, future operating and development costs, future commodity prices, estimated future cash flows, lease terms and expirations, and a market-based weighted-average cost of capital rate. These inputs require significant judgments and estimates by management at the time of the valuation and are the most sensitive and subject to change.

This acquisition was accounted for under the acquisition method. Accordingly, we conducted assessments of net assets acquired and recognized amounts for identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values, while transaction and integration costs associated with the acquisition were expensed as incurred.

Goodwill. Goodwill is calculated as the excess of the purchase price over the fair value of net assets acquired and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Among the factors that contributed to a purchase price in excess of the fair value of the net tangible and intangible assets acquired were the acquisition of an element of a workforce and the expected value from operations of the Delaware Basin acquisition to be derived in the future. The amount of goodwill that was recorded on a preliminary basis related to the Delaware Basin acquisition has decreased as compared to the initial estimated amount recorded as of December 31, 2016, due to customary purchase price allocations, primarily related to a refund from the sellers in connection with a revised valuation of certain acquired leases and the retirement of estimated environmental remediation liabilities. Such amounts will be sold.

finalized with final purchase accounting, as described above. Any value assigned to goodwill is not expected to be deductible for income tax purposes.

The liability associated with our non-qualified deferred compensation plan for non-employee directors may be settled in cash or shares of our common stock. The carrying value of this obligation is based on the quoted market price of our common stock, which is a Level 1 input. The liability related to this plan, which was included in other liabilities on the condensed consolidated balance sheets, was immaterial as of September 30, 2016 and December 31, 2015.
The portion of our long-term debt related to our revolving credit facility approximates fair value due to the variable nature of related interest rates. We have not elected to account for the portion of our debt related to our senior notes under the fair value option; however, as of September 30, 2016, we estimate the fair value of the portion of our long-term debt related to our 1.125% senior notes due 2021 to be $214.8 million, or 107.4% of par value, 6.125% senior notes due 2024 to be $415.6 million, or 103.9% of par value, and 7.75% senior notes due 2022 to be $530.3 million, or 106.1% of par value. We determined these valuations based upon measurements of trading activity and broker and/or dealer quotes, respectively, which are published market prices, and therefore are Level 2 inputs.

The carrying value of our capital lease obligations approximates fair value due to the variable nature of the imputed interest rates and the duration of the related vehicle lease.

Concentration of Risk

Derivative Counterparties. Our derivative arrangements expose us to credit risk of nonperformance by our counterparties. We primarily use financial institutions who are also lenders under our revolving credit facility as counterparties to our derivative contracts. To date, we have had no counterparty default losses relating to our derivative arrangements. We have evaluated the credit risk of our derivative assets from our counterparties using relevant credit market default rates, giving consideration to amounts outstanding for each counterparty and the duration of each outstanding derivative position. Based on our evaluation, we have determined that the potential impact of nonperformance of our counterparties on the fair value of our derivative instruments was not significant at September 30, 2016, taking into account the estimated likelihood of nonperformance.

The following table presents the counterparties that expose uschanges in goodwill:

Balance at June 30, 2017$56,331

With the creation of goodwill from this transaction, we will perform our evaluation of goodwill for impairment annually or when a triggering event is deemed to credit riskhave occurred. We evaluate goodwill for impairment by either performing a qualitative evaluation or a quantitative test, which involves comparing the estimated fair value to the carrying value. In either case, the valuation of goodwill will be a significant estimate as such methods incorporate forward-looking assumptions and estimates.

Note receivable, net$

In October 2014, we sold our entire 50% ownership interest in PDCM to an unrelated third-party. As part of the consideration, we received a promissory note (the “Note”) for a principal sum of $39 million, bearing interest at varying rates beginning at 8%, and increasing annually. Pursuant to the Note agreement, interest is payable quarterly, in arrears, commencing in December 2014 and continuing on the last business day of each fiscal quarter thereafter. At the option of the issuer of the Note, an unrelated third-party, interest can be paid-in-kind (the “PIK Interest”) and any such PIK Interest will be added to the outstanding principal amount of the Note. As of September 30, 2016, the issuer of the Note had elected the PIK Interest option. The principal and any unpaid interest is due and payable in full in September 2020 and can be prepaid in whole or in part at any time without premium or penalty. If an event of default occurs under the Note agreement, the Note must be repaid prior to maturity. Legally, the Note is secured by a pledge of stock in certain subsidiaries of the unrelated third-party, debt securities and other assets; however, we believe that collection of the Note is not reasonably assured.

On a quarterly basis, we examine the Note for evidence of impairment, evaluating factors such as the creditworthiness of the issuer of the Note and the value of the underlying assets that secure the Note. We performed our quarterly evaluation and cash flow analysis as of March 31, 2016 and, based upon the unaudited year-end financial statements and reserve report of the issuer of the Note received by us in late March 2016 and existing market conditions, determined that collection of the Note and PIK Interest was not reasonably assured. As a result, we recognized a provision and recorded an allowance for uncollectible notes receivable for the $44 million outstanding balance as of March 31, 2016, which was included in the condensed consolidated balance sheet line item other assets. As of September 30, 2016, there has been no change to our assessment of the collectibility of the note or related interest since March 31, 2016. Commencing in the second quarter of 2016, we ceased recognizing interest income on the Note and are accounting for the Note under the cash basis method.

Under the effective interest method, we recognized $1.2 million of interest income related to the Note for the three months ended March 31, 2016, of which $1 million was PIK Interest, and we recognized $1.1 million and $3.4 million of interest income related to the Note for the three and nine months ended September 30, 2015, respectively, of which $0.8 million and $2.4 million, respectively, was PIK Interest.

Additionally, during the three months ended March 31, 2016, we recorded a $0.7 million provision and allowance for uncollectible notes receivable to impair a promissory note related to a previous divestiture as collection of the promissory note was not reasonably assured based on the analysis we performed as of March 31, 2016. In August 2016, we collected the $0.7 million promissory note and reversed the related provision and allowance for uncollectible notes receivable during the three months ended September 30, 2016.

NOTE 45 - COMMODITY DERIVATIVE FINANCIAL INSTRUMENTS

Our results of operations and operating cash flows are affected by changes in market prices for crude oil, natural gas, and NGLs. To manage a portion of our exposure to price volatility from producing crude oil, and natural gas, we utilize the following economic hedging strategies for eachand propane, which is an element of our business segments.

For crude oil and natural gas sales,NGLs, we enter into commodity derivative contracts to protect against price declines in future periods. While we structure these commodity derivatives to reduce our exposure to changesdecreases in price associated with the derivative commodity prices, they also limit the benefit we might otherwise have receivedreceive from price increases in the physical market; andincreases.
 
For natural gas marketing, we enter into fixed-price physical purchase and sale agreements that qualify as derivative contracts. In order to offset the fixed-price physical derivatives in our natural gas marketing, we enter into financial derivative instruments that have the effect of locking in the prices we will receive or pay for the same volumes and period, offsetting the physical derivative.

We believe our commodity derivative instruments continue to be effective in achieving the risk management objectives for which they were intended. As of SeptemberJune 30, 2016,2017, we had derivative instruments, which were comprised of collars, fixed-price swaps, and basis protection swaps, and physical sales and purchases, in place for a portion of our anticipated 2017 and 2018 production through 2018 for a total of 90,42512,896 MBbls of crude oil, 82,030 BBtu of natural gas, and

Net settlements of commodity derivatives decreased for the three and six months ended June 30, 2017 as compared to the three and six months ended June 30, 2016.  We entered into agreements for the derivative instruments that settled throughout 2016 prior to commodity prices becoming depressed in late 2014.  Substantially all of these higher-value agreements settled by the end of 2016.  Net settlements for the three and six months ended June 30, 2017 reflect derivative instruments entered into since 2015, which more closely approximate recent realized prices.  Based upon the forward strip pricing at June 30, 2017, we expect that settlements will continue to be substantially lower in 2017 on a relative basis as compared to those in 2016.

All of our financial derivative agreements contain master netting provisions that provide for the net settlement of all contracts through a single payment in the event of early termination. Our fixed-price physical purchase and sale agreements that qualify as derivative contracts are not subject to master netting provisions and are not significant. We have elected not to offset the fair value positions recorded on our condensed consolidated balance sheets.

Our fair value measurements are estimated pursuant to a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date, giving the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability, and may affect the valuation of the assets and liabilities and their placement within the fair value hierarchy levels. The three levels of inputs that may be used to measure fair value are defined as:

In September 2016, we closed on an acreage exchange transaction with Noble Energy, Inc.Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable for the asset or liability, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability, and certaininputs that are derived from observable market data by correlation or other means.

Level 3 – Unobservable inputs for the asset or liability, including situations where there is little, if any, market activity.

Derivative Financial Instruments

We measure the fair value of its subsidiaries ("Noble")our derivative instruments based upon a pricing model that utilizes market-based inputs, including, but not limited to, consolidate certain acreage positions in the core areacontractual price of the Wattenberg Field. Pursuant to the transaction, we exchanged leasehold acreage and, to a lesser extent, interests in certain development wells. Upon closing, we received approximately 13,500 net acres in exchange for approximately 11,700 net acres, with no cash exchanged between the parties.

The following table presents impairment charges recorded forunderlying position, current market prices, crude oil and natural gas properties:forward curves, discount rates such as the LIBOR curve for a similar duration of each outstanding position, volatility factors, and nonperformance risk. Nonperformance risk considers the effect of our credit standing on the fair value of derivative liabilities and the effect of our counterparties' credit standings on the fair value of derivative assets. Both inputs to the model are based on published credit default swap rates and the duration of each outstanding derivative position.

We validate our fair value measurement through the review of counterparty statements and other supporting documentation, determination that the source of the inputs is valid, corroboration of the original source of inputs through access to multiple quotes, if available, or other information, and monitoring changes in valuation methods and assumptions. While we use common industry practices to develop our valuation techniques and believe our valuation method is appropriate and consistent with those used by other market participants, changes in our pricing methodologies or the underlying assumptions could result in significantly different fair values.

Our crude oil and natural gas fixed-price swaps are included in Level 2. Our collars, physical sales, and propane fixed-price swaps are included in Level 3. Our basis swaps are included in Level 2 and Level 3. The following table presents, for each applicable level within the fair value hierarchy, our derivative assets and liabilities, including both current and non-current portions, measured at fair value on a recurring basis:

NOTE 6 - PENDING ACQUISITION
In August 2016, we entered into acquisition agreements to purchase Arris Petroleum Corporation (“Arris”) and the assets of 299 Resources, LLC, 299 Production, LLC and 299 Pipeline, LLC (collectively, “299 Sellers”) pursuant to which, and subject to the terms and conditions of those agreements, we have agreed to acquire an aggregate of approximately 57,000 net acres, approximately 30 wells and other related midstream infrastructure in Reeves and Culberson Counties, Texas, for an aggregate consideration to Arris and 299 Sellers of approximately $915 million in cash and approximately 9.4 million shares of our common stock (valued at approximately $590 million at the time the acquisition agreements were executed), subject to certain adjustments, and ongoing due diligence (the "Delaware Basin Acquisition"). The acquisition agreements allow the sellers to include a specified amount of additional leases in the transaction, which would increase the purchase price. Upon executing the acquisition agreements, we paid a $100 million deposit toward the cash portion of the purchase price into an escrow account, which is included in other assets in our September 30, 2016 condensed consolidated balance sheet. In some circumstances set forth in the acquisition agreements, we could be required to forfeit the $100 million deposit. The acquisition is expected to close in December 2016; however, there can be no assurance that conditions to closing will be satisfied.
In order to fund the cash portion of the Delaware Basin Acquisition, we completed a public offering of shares of our common stock, a public offering of convertible senior notes and a private offering of senior notes in September 2016. See Note 8, Long-Term Debt, and Note 12, Common Stock, for further information. Prior to the September 2016 issuances of common stock, convertible senior notes and senior notes, we entered into a commitment letter with JPMorgan Chase Bank, N.A. (“JPMorgan”), for short-term bridge financing of the Delaware Basin Acquisition. The commitment letter contemplated, among other things, (i) a senior unsecured bridge loan to us in an aggregate principal amount not to exceed $600 million, to be drawn, if at all, at the closing of the Delaware Basin Acquisition, (ii) a $250 million increase in the commitments under our existing revolving credit facility and (iii) certain related proposed amendments and waivers to our existing credit facility agreement. Upon issuance of the common stock, convertible senior notes and senior notes, the bridge loan commitment was terminated. Upon closing of

The significant unobservable input used in the Delaware Basin Acquisition,fair value measurement of our derivative contracts is the implied volatility curve, which is provided by a third-party vendor. A significant increase or decrease in the implied volatility, in isolation, would have a directionally similar effect resulting in a significantly higher or lower fair value measurement of our Level 3 derivative contracts. There has been no change in the methodology we apply to measure the fair value of our Level 3 derivative contracts during the periods covered by this report.
Non-Derivative Financial Assets and Liabilities

The carrying value of the financial instruments included in current assets and current liabilities approximate fair value due to the short-term maturities of these instruments.

We utilize fair value on a nonrecurring basis to review our crude oil and natural gas properties and goodwill for possible impairment when events and circumstances indicate a possible decline in the recoverability of the carrying value of such assets. The fair value of the properties is determined based upon estimated future discounted cash flow, a Level 3 input, using estimated production and prices at which we reasonably expect the crude oil and natural gas will be required to pay approximately $9 millionsold. The fair value of the goodwill is determined using either a qualitative method or a quantitative method, both of which utilize market data, a Level 2 input, in feesthe derivation of the value estimation.
The portion of our long-term debt related to the bridge loan commitment, approximately $6 million in fees related to the increase in commitments under theour revolving credit facility approximates fair value due to the variable nature of related interest rates. We have not elected to account for the portion of our debt related to our senior notes under the fair value option; however, we have determined an estimate of the fair values based on measurements of trading activity and broker and/or dealer quotes, respectively, which are published market prices, and therefore are Level 2 inputs. The table below presents these estimates of the fair value of the portion of our long-term debt related to our senior notes and convertible notes as of June 30, 2017.

 2022 Senior Notes520.6

The carrying value of our capital lease obligations approximates fair value due to the variable nature of the imputed interest rates and the duration of the related vehicle lease.

Concentration of Risk

Derivative Counterparties. A portion of our liquidity relates to commodity derivative instruments that enable us to manage a portion of our exposure to price volatility from producing crude oil and natural gas. These arrangements expose us to credit risk of nonperformance by our counterparties. We primarily use financial institutions who are also major lenders under our revolving credit facility as counterparties to our commodity derivative contracts. An insignificant portion of our commodity derivative instruments may be with other counterparties. To date, we have had no derivative counterparty default losses. We have evaluated the credit risk of our derivative assets from our counterparties using relevant credit market default rates, giving consideration to amounts outstanding for each counterparty and the duration of each outstanding derivative position. Based on our evaluation, we have determined that the potential impact of nonperformance of our current counterparties on the fair value of our derivative instruments is not significant at June 30, 2017, taking into account the estimated likelihood of nonperformance.

Cash and Cash Equivalents. We consider all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents potentially subject us to a concentration of credit risk as substantially all of our deposits held in financial institutions were in excess of the FDIC insurance limits at June 30, 2017. We maintain our cash and cash equivalents in the form of money market and checking accounts with financial institutions that we believe are creditworthy and are also major lenders under our revolving credit facility.

Notes Receivable. In October 2014, we sold our entire 50 percent ownership interest in PDC Mountaineer, LLC to an unrelated third-party. As part of the consideration, we received a promissory note (the “Promissory Note”) for a principal sum of $39.0 million, bearing varying interest rates. The interest was to be paid quarterly, in arrears and at the option of the issuer, could be paid-in-kind (“PIK Interest”) and any such PIK Interest would be subject to the then current interest rate.

We regularly analyzed the Promissory Note for evidence of collectability, evaluating factors such as the creditworthiness of the issuer of the Promissory Note and the value of the underlying assets that secure the Promissory Note. Based upon this analysis, during the quarter ended March 31, 2016, we recognized a provision and recorded an allowance for uncollectible notes receivable for the $44.0 million accumulated outstanding balance, including interest. Commencing in the second quarter of 2016, we ceased recognizing interest income on the Promissory Note and began accounting for the interest on the Promissory Note under the cash basis method.

We performed this analysis as of March 31, 2017 and evaluated preliminary 2016 year-end financial statements of the note issuer which were available at such time, related information about the operations of the issuer, and existing market conditions for natural gas. Based upon this evaluation, it was determined that collection of the Promissory Note and PIK Interest continued to be doubtful and the full valuation allowance on the Promissory Note remained appropriate as of that date. This evaluation assumed repayment of the Promissory Note would be made exclusively from the existing operations of the issuer of the Promissory Note based on the latest available information.

In April 2017, we sold the Promissory Note to an unrelated third-party buyer for approximately $10$40.2 million in other direct acquisition-related costs. Duringcash. The sales agreement transferred all of our legal rights to collect from the issuer of the Promissory Note. Accordingly, we reversed $40.2 million of the provision for uncollectible notes receivable during the three months ended SeptemberJune 30, 2016, we recorded charges for the bridge loan fees and the other direct acquisition-related costs. The $9 million charge for fees related to the bridge loan commitment is included in interest expense and the $10 million charge for other direct acquisition-related costs is included in general and administrative expenses. The liabilities associated with both amounts are included in other accrued expenses on our condensed consolidated balance sheet as of September 30, 2016.2017.

NOTE 7 - INCOME TAXES

We evaluate and update our estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. Consequently, based upon the mix and timing of our actual annual earnings compared to annual projections, our effective tax rate may vary quarterly and may make quarterly comparisons not meaningful. A tax expense or benefit unrelated to the current year income or loss is recognized in its entirety as a discrete item of tax in the period identified. The quarterly income tax provision is generally comprised of tax expense on income or benefit on loss at the most recent estimated annual effective income tax rate, adjusted for the effect of discrete items.

The effective income tax rates for the three and six months ended June 30, 2017, are based upon a full year forecasted tax benefitprovision on lossincome and isare greater than the statutory federal income tax rate, primarily due to state income taxes, nondeductible officers’ compensation and nondeductible lobbying expenses, partially offset by stock-based compensation tax deductions. We anticipate the potential for increased periodic volatility in future effective income tax rates from the impact of stock-based compensation tax deductions as they are treated as discrete tax items. The effective income tax rates for the three and six months ended June 30, 2016, were based upon a full year forecasted income tax benefit on loss and were greater than the statutory federal income tax rate, primarily due to state income taxes and percentage depletion, partially offset by nondeductible officers’ compensation and nondeductible lobbying expenses. The effective tax rate for the three and nine months ended September 30, 2015 differs from the statutory rate primarily due to state taxes and percentage depletion, partially offset by nondeductible officers' compensation.

In periods subsequent to initial measurement of the liability, we must recognize period-to-period changes in the liability resulting from the passage of time, revisions to either the amount of the original estimate of undiscounted cash flows or changes in inflation factors, and changes to our credit-adjusted risk-free rate as market conditions warrant.

Firm Transportation Processing and SalesProcessing Agreements. We enter into contracts that provide firm transportation sales and processing agreements on pipeline systems through which we transport or sell crude oil and natural gas. Satisfaction of the volume requirements includes volumes produced by us, purchased from third parties, and produced by our affiliated partnerships and other third-party working, royalty, and overriding royalty interest owners. We record in our financialowners whose volumes we market on their behalf. Our condensed consolidated statements onlyof operations reflect our share of costs based upon our working interest in the wells.these firm transportation and processing costs. These contracts require us to pay these transportation and processing charges whether or not the required volumes are delivered. As natural gas prices continue to remain depressed, certain third-party producers under our Gas Marketing segment have begun and continue to experience financial distress, which has led to certain contractual defaults and litigation; however, to date, we have had no material counterparty default losses.

In December 2016, in anticipation of our future drilling activities in the Wattenberg Field, we entered into a facilities expansion agreement with our primary midstream provider to expand and improve its natural gas gathering pipelines and processing facilities. The midstream provider is expected to construct a new 200 MMcfd cryogenic plant. We will be bound to the volume requirements in this agreement on the first day of the calendar month after the actual in-service date of the plant, which in the above table is estimated to be in October 2018. The agreement requires a baseline volume commitment, consisting of our gross wellhead volume delivered in November 2016, to this midstream provider and an incremental wellhead volume commitment of 51.5 MMcfd for seven years. We may be required to pay a shortfall fee for any volumes under the 51.5 MMcfd incremental commitment. Any shortfall of this volume commitment may be offset by additional third party producers’ volumes sold to the midstream provider that are greater than a certain total baseline volume. We are also required for the first three years of the contract to guarantee a certain target profit margin to the midstream provider on these incremental volumes. We expect that our development plan will support the utilization of that capacity.

In April 2017, we entered into a transportation service agreement for delivery of 40,000 dekatherms per day of our Delaware Basin natural gas production to the Waha market hub in West Texas. 

For each of the three and six months ended June 30, 2017, commitments for long-term transportation volumes, net to our interest, for Wattenberg Field crude oil, Delaware Basin natural gas, and Utica Shale natural gas were $2.6 million and $4.8 million, respectively, and were recorded in transportation, gathering, and processing expense in our condensed consolidated statements of operations. For each of the three and six months ended June 30, 2016, commitments for long-term transportation volumes for Wattenberg Field crude oil and Utica Shale natural gas were $2.3 million and $4.7 million, respectively.

During the three and six months ended June 30, 2017, long-term firm transportation costs for our gas marketing business associated with the commitments shown above were $0.9 million and $1.7 million, respectively, and were recorded in other expenses in our condensed consolidated statements of operations. During the three and six months ended June 30, 2016, long-term firm transportation costs for our gas marketing business associated with the commitments shown above were $0.9 million and $1.7 million, respectively.

A group of 42 independent West Virginia natural gas producers has filed a lawsuit in Marshall County, West Virginia, naming Dominion Transmission, Inc. (“Dominion”), certain entities affiliated with Dominion, and RNG as defendants, alleging various contractual, fiduciary and related claims against the defendants, all of which are associated with firm transportation contracts entered into by plaintiffs and relating to pipelines owned and operated by Dominion and its affiliates. RNG and Dominion have removed the case to the U.S. District Court for the Northern District of West Virginia and are preparing pre-trial pleadings, including an answer to the complaint and a motion to dismiss the case. At this time, RNG is unable to estimate any potential damages associated with the claims, but believes the complaint is without merit and intends to vigorously pursue its defenses.

Environmental.Due to the nature of the natural gas and oil industry, we are exposed to environmental risks. We have various policies and procedures to minimize and mitigate the risks from environmental contamination. We conduct regularperiodic reviews and simulated drills to identify changes in our environmental risk profile. Liabilities are recorded when environmental damages resulting from past events that require remediation are probable and the costs can be reasonably estimated. As of September 30, 2016 and December 31, 2015,Except as discussed herein, we had accrued environmental liabilities in the amount of $3.2 million and $4.1 million, respectively, included in other accrued expenses on the condensed consolidated balance sheets. We are not aware of any environmental claims existing as of SeptemberJune 30, 20162017 which have not been provided for or would otherwise have a material impact on our financial statements; however, there can be no assurance that current regulatory requirements will not change or that unknown past non-compliance with environmental laws will not be discovered on our properties. However, the liability ultimately incurred with respect to a matter may exceed the related accrual. Accrued environmental liabilities are recorded in other accrued expenses on the condensed consolidated balance sheets.

In August 2015, we received a Clean Air Act Section 114 Information Request (the "Information Request") from the U.S. Environmental Protection Agency ("EPA"). The Information Request sought, among other things, information related to the design, operation, and maintenance of our Wattenberg Field production facilities in the Denver-Julesburg Basin of Colorado. The Information Request focusedfocuses on historical operation and design information for 46 of our production facilities and asks that we conduct sampling and analyses at the identified 46 facilities. We responded to the Information Request with the requested data in January 2016. We continue to meet with the EPA and provide additional information, but cannot predict the outcome of this matter at this time.

In addition, in December 2015, we received a Compliance Advisory pursuant to C.R.S. § 25-7-115(2) from the Colorado Department of Public Health and Environment's (“CDPHE”) Air Quality Control Commission's Air Pollution Control Division alleging that we failed to design, operate, and maintain certain condensate collection, storage, processing, and handling operations to minimize leakage of volatile organic compounds to the maximum extent possible at 65 facilities consistent with applicable standards under Colorado law. We are working with the agency to address the allegations, but cannot predict the outcome of this matter at this time.

Treasury Share Purchases

In June 2010, our stockholders approved a long-term equity compensation plan for our employees and non-employee directors (the "2010 Plan"). In accordance with the 2010 Plan, as amended in June 2013, up to 3,000,000 new shares of our common stock are authorized for issuance. Shares granted may be either authorized but unissued shares, treasury shares, or any combination of these shares. Additionally, the 2010 Plan permits the reuse or reissuance of shares of common stock which were canceled, expired, forfeited or, in the case of SARs, paid out in the form of cash. In accordance with our stock-based compensation plans, employees and directors may surrender shares of our common stock to pay tax withholding obligations upon the vesting and exercise of share-based awards. Shares acquired that had been issued pursuant to the 2010 Plan are reissued for new grants. For shares reissued for new grants under the 2010 Plan, shares are recorded at cost and upon reissuance we reduce the carrying value of shares acquired and held pursuant to the 2010 Plan by the weighted-average cost per share with an offsetting charge to additional paid-in capital. As of December 31, 2016, we had 10,397 shares remaining available for reissuance pursuant to our 2010 plan. Additionally, as of December 31, 2016, we had 18,366 of shares of treasury stock related to a rabbi trust. During the six months ended June 30, 2017, we acquired 79,381 shares pursuant to our stock-based compensation plans for payment of tax liabilities, of which 46,822 shares were reissued and 42,956 shares are available for reissuance pursuant to our 2010 Plan.

Preferred Stock

We are authorized to issue 50,000,000 shares of preferred stock, par value $0.01 per share, which may be issued in one or more series, with such rights, preferences, privileges, and restrictions as shall be fixed by our Board from time to time. Through June 30, 2017, no preferred shares have been issued.

Diluted earnings per share is similarly computed, except that the denominator includes the effect, using the treasury stock method, of unvested restricted stock, outstanding SARs, stock options, convertible notes, and shares held pursuant to our non-employee director deferred compensation plan, if including such potential shares of common stock is dilutive.

The following table presents a reconciliation of the weighted-average diluted shares outstanding:

In September 2016, we issued the 2021 Convertible Notes, which give the holders, at our election, the right to convert the aggregate principal amount into 2.3 million shares of our common stock at a conversion price of $85.39 per share. The 2021 Convertible Notes could be included in the diluted earnings per share calculation using the treasury stock method if the average market share price exceeds the $85.39 conversion price during the periods presented.

our common stock did not exceed the conversion price; therefore, shares issuable upon conversion of the 2021 Convertible Notes were not included in the diluted earnings per share calculation.


In November 2010, we issued the $115.0 million aggregate principal amount of 3.25% convertible senior notes that were due in 2016 ("2016 Convertible Notes,Notes"), which gave the holders the right to convert the aggregate principal amount into 2.7 million shares of our common stock at a conversion price of $42.40 per share. The 2016 Convertible Notes matured in May 2016. See Note 8, Long-Term Debt, for additional information. Prior to maturity, the 2016 Convertible Notes were included in the diluted earnings per share calculation using the treasury stock method ifwhen the average market share price exceeded the $42.40 conversion price during the periodperiods presented.

Shares issuable upon conversion of the 2021 Convertible Notes and 2016 Convertible Notes were excluded from the diluted earnings per share calculation for the applicable periods as the effect would be anti-dilutive to our earnings per share.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis, as well as other sections in this report, should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this report. Further, we encourage you to revisitreview the Special Note Regarding Forward-Looking Statements.

EXECUTIVE SUMMARY

Financial Overview

Production volumes increased substantially to 6.08.0 MMboe and 15.814.7 MMboe for the three and ninesix months ended SeptemberJune 30, 2016,2017, respectively, representing increases of 39% 54 percentand 49%, respectively,50 percent as compared to the three and ninesix months ended SeptemberJune 30, 2015.2016, respectively. The increaseincreases in production volumes waswere primarily attributable to the continued success of our successful horizontal Niobrara and Codell drilling program in the Wattenberg Field. Field and our first full six months of production from our recently-acquired Delaware Basin properties.Crude oil production increased 17%62 percent and 27%47 percent for the three and ninesix months ended SeptemberJune 30, 2016,2017, respectively, compared to the same prior year periods.three and six months ended June 30, 2016. Crude oil production comprised approximately 39%40 percent and 40% 39 percentof total production in the three and ninesix months ended SeptemberJune 30, 2016. Our ratio of crude oil production to total production decreased as compared to 2015 as expected as we shifted our focus to the higher gas to oil ratio inner core area of the Wattenberg Field during the first half of 2016. We expect our ratio of crude oil to total production to increase by the end of 2016 as we move drilling operations back toward the middle core area of the Wattenberg Field. Natural gas2017, respectively. NGL production increased 47%66 percent and 60% in70 percent for the three and ninesix months ended SeptemberJune 30, 2016,2017, respectively, compared to the three and ninesix months ended SeptemberJune 30, 2015. NGL2016. Natural gas production increased 80%40 percent and 83% for43 percent in the three and ninesix months ended SeptemberJune 30, 2016,2017, respectively, compared to the same prior year periods. Our inner core wells have shown stronger wet gasthree and six months ended June 30, 2016.On a combined basis, total liquids production than anticipated, which has contributed tocomprised 63 percent and 59 percent of our total production during the growththree months ended June 30, 2017 and June 30, 2016, respectively, and 62 percent and 60 percent of gastotal production during the six months ended June 30, 2017 and NGL production. OurJune 30, 2016, respectively. For the three months ended June 30, 2017, we maintained an average daily production rate of approximately 88,100 Boe per day, up from approximately 57,100 Boe per day for the three months ended SeptemberJune 30, 2016 increased approximately 0.8 MMboe, or 16%,2016.

On a sequential quarterly basis, total production volumes for the three months ended June 30, 2017, as compared to the three months ended JuneMarch 31, 2017, increased by 21 percent, while crude oil production increased by 30 2016. We expect a modestpercent during the same period. The increase in production forwas primarily related to 84 wells in our Wattenberg Field being turned-in-line during the first six months of 2017 and a 47 percent increase in our average daily production in the Delaware Basin from the first quarter, to approximately 10,000 Boe per day in the quarter ended June 30, 2017. We expect that we will see modest sequential production growth in the third quarter of 2017 and leveling off of production in the fourth quarter of 2016 as compared to2017, based on the third quarter, as we have approximately 20 fewer wells scheduled to be turned-in-line duringadjusted timing for our turn-in-lines, and expected capacity considerations associated with gathering system line pressures in the fourth quarter, and we expect all remaining 2016 well completions to be concluded by the middle of the fourth quarter of 2016. For the month ended September 30, 2016, our average production rate was 63 MBoe per day, up from 47 MBoe per day for the month ended September 30, 2015.Wattenberg Field.

Crude oil, natural gas and NGLs sales, coupled with the impact of settled derivatives, increased during the three and nine months ended September 30, 2016 relative to the same prior year periods. Crude oil, natural gas, and NGLs sales increased to $141.8$213.6 million and $328$403.3 million duringin the three and ninesix months ended SeptemberJune 30, 20162017, respectively, compared to $104.5$110.8 million and $275.5$186.2 million in the same prior year periods due to 39%three and 49%six months ended June 30, 2016, respectively. These 93 percent and 117 percent increases in sales revenues were driven by the 54 percentand 50 percent increases in production respectively, offsetand 25 percent and 44 percent increases in part by 2% and 20% decreases, respectively, in the realized price per barrel of crude oil equivalent ("Boe"). The realized prices per Boe were $23.62 and $20.80 for the three and nine months ended September 30, 2016, respectively, compared to $24.15 and $26.02, respectively, for the same prior year periods. Positivecommodity prices.

We had positive net settlements on derivatives decreased to $47.7from our commodity derivative contracts of $12.0 million for the three months ended SeptemberJune 30, 2016 and increased to $167.9 million during the nine months ended September 30, 20162017 as compared to positive net settlements onof $53.3 million for the three months ended June 30, 2016. We had positive net settlements of $12.6 million for the six months ended June 30, 2017, as compared to positive net settlements of $120.1 million for the six months ended June 30, 2016. We entered into agreements for the derivative instruments that settled throughout 2016 prior to commodity prices becoming depressed in late 2014.  Substantially all of these higher-value derivatives settled by the end of $68 million2016.  Net settlements for the three and $162.5 millionsix months ended June 30, 2017 reflect derivative instruments entered into since 2015, which more closely approximate recent realized prices.  Based upon the forward strip pricing at June 30, 2017, we expect that settlements will continue to be substantially lower in 2017 than in 2016. See Results of Operations - Commodity Price Risk Management, Net for further details of our settlements of derivatives and changes in the same prior year periods. As a resultfair value of these aggregate changes,unsettled derivatives.

The combined revenue from crude oil, natural gas, and NGLs sales and the impact of net settled derivatives totaled $189.5 million and $495.9 million during the three and nine months ended September 30, 2016, respectively, compared to $172.5 million and $438 million during the three and nine months ended September 30, 2015, respectively. This represents increases of 10% and 13% during the three and nine months ended September 30, 2016, respectively, compared to the same prior year periods. The realized prices per Boe, including the impact of net settlements received on derivatives, were $31.56 and $31.44 for the three and nine months ended September 30, 2016, respectively, compared to $39.88 and $41.37 for the same prior year periods, respectively.

Additional significant changes impacting our results of operations for the three months ended September 30, 2016 include the following:

Negative net change in the fair value of unsettled derivative positions during the three months ended September 30, 2016 was $28.3 million compared to a positive net change in the fair value of unsettled derivative positions of $55.5 million during the same prior year period. The decrease in fair value of unsettled derivative positions was primarily attributable to a less significant upward shift in the crude oil and natural gas forward curves, offset by the impact of the beginning of period fair value ofcommodity derivative instruments settled in the respective periods, during the current quarter as comparedincreased 37 percent to the three months ended September 30, 2015;
Impairment of properties and equipment decreased to $0.9$225.6 million for the three months ended September 30, 2016 compared to $154 million in the same prior year period, primarily related to the $150.3 million write-down of our Utica Shale producing and non-producing crude oil and natural gas properties to their estimated fair value in the three months ended SeptemberJune 30, 2015;
General and administrative expense increased to $32.52017, from $164.1 million forin the three months ended SeptemberJune 30, 2016, comparedand increased 36 percent to $20.3$415.9 million in the same prior year period, primarily due to $11.3 million of fees and expenses related to the pending Delaware Basin Acquisition;
Depreciation, depletion and amortization expense increased to $112.9 million during the threesix months ended SeptemberJune 30, 2016 compared to $80.92017, from $306.3 million in the same prior year period, primarily due to increased production; and
Interest expense increased to $20.2 million for the threesix months ended SeptemberJune 30, 2016 compared to $12.1 million in the same prior year period, primarily attributable to a $9 million charge for the bridge loan commitment related to the Delaware Basin Acquisition.2016.

Additional significant changes impacting our results of operations for the nine months ended September 30, 2016 include the following:

Negative net change in the fair value of unsettled derivative positions during the nine months ended September 30, 2016 was $230.2 million compared to a negative net change in the fair value of unsettled derivative positions of $21.3 million during the same prior year period. The decrease in fair value of unsettled derivative positions was primarily attributable to an upward shift in the crude oil and natural gas forward curves that occurred during 2016;
Impairment of properties and equipment decreased to $6.1 million for the nine months ended September 30, 2016 compared to $161.2 million in the same prior year period, primarily related to the $150.3 million write-down of our Utica Shale producing and non-producing crude oil and natural gas properties to their estimated fair value in the three months ended September 30, 2015;
General and administrative expense increased to $78.9 million for the nine months ended September 30, 2016 compared to $62.1 million in the same prior year period, primarily due to $11.3 million of fees and expenses related to the Delaware Basin Acquisition;
Depreciation, depletion and amortization expense increased to $317.3 million during the nine months ended September 30, 2016 compared to $206.9 million in the same prior year period, primarily due to increased production and, to a lesser extent, a higher weighted-average depreciation, depletion and amortization rate;
During the first quarter of 2016, we determined that collection of a third-party note receivable arising from the sale of our interest in properties in the Marcellus Shale was not reasonably assured based then current market conditions and new information made available to us. As a result, we recognized a provision and recorded an allowance for uncollectible notes receivable for the $44 million outstanding balance as of March 31, 2016. As of September 30, 2016, there has been no change to our assessment of the collectibility of the note. See Note 3, Fair Value of Financial Instruments - Notes Receivable, to our condensed consolidated financial statements included elsewhere in this report for additional information; and
Interest expense increased to $42.8 million for the nine months ended September 30, 2016 compared to $35.4 million in the same prior year period, primarily attributable to a $9 million charge for the bridge loan commitment related to the Delaware Basin Acquisition.

In March 2016, we completed a public offering of 5,922,500 shares of our common stock at a price to us of $50.11 per share. Net proceeds of the offering were $296.6 million, after deducting offering expenses and underwriting discounts. We used a portion of the net proceeds of the offering to repay all amounts then outstanding on our revolving credit facility and the principal amount owed upon the maturity of the Convertible Notes in May 2016 and retained the remainder for general corporate purposes.

The 2016 Convertible Notes matured in May 2016. We settled the 2016 Convertible Notes with a combination of cash and stock, paying the aggregate principal amount, plus cash for fractional shares, totaling approximately $115 million, utilizing proceeds from the offering. Additionally, we issued 792,406 shares of common stock for the excess conversion value.

In June 2016, we entered into definitive agreements with Noble to consolidate certain acreage positions in the core Wattenberg Field.
In September 2016, we closed the acreage exchange transaction. Pursuant to the transaction, we exchanged leasehold acreage and, to a lesser extent, interests in certain development wells. Upon closing, we received approximately 13,500 net acres in exchange for approximately 11,700 net acres, with no cash exchanged between the parties. The difference in net acres is primarily due to variances in leasehold net revenue interests and third-party mid-stream contracts. This acreage trade is expected to increase opportunities for longer horizontal laterals with significantly increased working interests, while minimizing potential surface impact.

Pending Delaware Basin Acquisition

We seek acquisition opportunities as part of our overall growth strategy, and in particular have recently engaged in the process of searching for, and evaluating, a large-scale acquisition in a new U.S. onshore basin capable of creating material long-term value-added growth, focusing on four key criteria: top-tier acreage in core geologic positions, significant drilling inventory with additional expansion through downspacing, portfolio optionality for capital allocation and diversification and the ability to deliver long-term corporate accretion.  In August 2016, we identified a potential acquisition, which we refer to as the Delaware Basin Acquisition, that we believe met our four key criteria.

We entered into definitive agreements relating to the Delaware Basin Acquisition in August 2016. The agreements contemplate that we will acquire an aggregate of approximately 57,000 net acres, approximately 30 wells and related midstream infrastructure in Reeves and Culberson Counties, Texas, for an aggregate consideration to the sellers of approximately $915 million in cash and approximately 9.4 million shares of our common stock (valued at approximately $590 million at the time the acquisition agreements were executed), subject to certain adjustments and ongoing due diligence. The acquisition agreements allow the sellers to include a specified amount of additional leases in the transaction, which would increase the purchase price. Upon executing the acquisition agreements, we paid a $100 million deposit toward the cash portion of the purchase price into an escrow account. In some circumstances set forth in the acquisition agreements, we could be required to forfeit the $100 million deposit. The Delaware Basin Acquisition is expected to initially increase our daily production by approximately 7,000 Boe per day. The acquisition is expected to close in December 2016; however, there can be no assurance conditions to closing will be satisfied. Upon closing, we currently expect to initially run a two rig drilling program in the Delaware Basin. We are currently completing our budgeting process for 2017, but anticipate running two to three rigs in the Delaware Basin during 2017. Taking into account the anticipated plans for the Delaware Basin Acquisition properties, we expect that pursuit of our development program will require capital in excess of our projected cash flows from operations for some period of time beginning in 2017.

In order to fund the cash portion of the Delaware Basin Acquisition, we completed a public offering of 9,085,000 shares of our common stock, a public offering of the 2021 Convertible Notes and a private offering of the 2024 Senior Notes in September 2016 (collectively, the "Securities Issuances"). The common stock was issued at a price to us of $61.51 per share for net proceeds of approximately $558.5 million, after deducting offering expenses and underwriting discounts. Net proceeds of the issuances of the 2021 Convertible Notes and 2024 Senior Notes were approximately $194 million and $392.3 million, respectively, after deducting offering expenses and underwriting discounts. If the Delaware Basin Acquisition is not completed on or prior to December 31, 2016 (or in some circumstances by or on January 15, 2017), the 2024 Senior Notes will be redeemed in whole at a special mandatory redemption price equal to 100% of the aggregate principal amount of the 2024 Senior Notes, plus accrued and unpaid interest.

Prior to the Securities Issuances, we entered into a commitment letter with JPMorgan regarding certain aspects of the temporary financing of the Delaware Basin Acquisition. The commitment letter contemplated, among other things, (i) a senior unsecured bridge loan to us in an aggregate principal amount not to exceed $600 million, to be drawn, if at all, at the closing of the Delaware Basin Acquisition, (ii) a $250 million increase in the commitments under our existing revolving credit facility and (iii) certain related proposed amendments and waivers to our existing credit facility agreement. We expect to fund the cash consideration payable in the Delaware Basin Acquisition with proceeds from the Securities Issuances. Following the completion of the Securities Issuances, the bridge loan commitment was terminated. Upon closing of the Delaware Basin Acquisition, we will be required to pay approximately $9 million in fees related to the bridge loan commitment, approximately $6 million in fees related to the increase in commitments under the revolving credit facility and approximately $10 million in other direct acquisition-related costs. During the three months ended SeptemberJune 30, 2017, we impaired certain unproved Delaware Basin leasehold positions totaling $27.0 million that expired during the three months ending June 30, 2017, or are projected to expire between June 30, 2017 and December 31, 2017.  Subsequent to closing the acquisitions in the Delaware Basin, it was determined that development of certain acreage tracts would not meet our internal expectations for acceptable rates of return due to a combination of weakening commodity prices; higher per well development and operational costs; and updated technical analysis.  As a result, we allowed or expect to allow certain acreage to expire, and in other circumstances we were unable to obtain necessary lease term extensions. As of June 30, 2017, our current leasehold position in the Delaware Basin is approximately 60,000 net acres.

In the three and six months ended June 30, 2017, we generated net income of $41.2 million and $87.4 million, respectively, or$0.62 and $1.32 per diluted share, respectively. During the same periods, our adjusted EBITDAX, a non-U.S. GAAP financial measure, was $200.4 million and $330.6 million, respectively. Our net income and adjusted EBITDAX were positively impacted by the sale of the $40.2 million Promissory Note and the collection of the related cash proceeds in April 2017, as further described below in Results of Operations - Provision for Uncollectible Notes Receivable. Beginning in 2017, we have included non-cash stock-based compensation and exploration, geologic and geophysical expense in our reconciliation of adjusted EBITDAX.  In prior periods, we included adjusted EBITDA, a non-U.S. GAAP financial measure, which did not include these adjustments.  All prior periods have been conformed for comparability of this updated presentation. In the three and six months ended June 30, 2016, we recorded chargesour net loss per diluted share was $2.04 and $3.78, respectively, and our adjusted EBITDAX, a non-GAAP financial measure, was $122.4 million and $180.2 million, respectively. Our cash flow from operations was $263.2 million and our adjusted cash flow from operations, a non-U.S. GAAP financial measure, was $256.6 million in the six months ended June 30, 2017. See Reconciliation of Non-U.S. GAAP Financial Measures, below, for the bridge loan commitment feesa more detailed discussion of these non-U.S. GAAP financial measures and the other direct acquisition-related costs. The $9 million charge for fees relateda reconciliation of these measures to the bridge loan commitment is included in interest expense and the $10 million charge for other direct acquisition-related costs is included in general and administrative expenses. The liabilities associated with both amounts are included in other accrued expenses on our condensed consolidated balance sheet as of September 30, 2016.most comparable U.S. GAAP measures.

Liquidity

Available liquidity as of SeptemberJune 30, 20162017 was $1,636$902.3 million, compared to $402.2 million as of December 31, 2015. Available liquidity as of September 30, 2016which is comprised of $1,197.7$202.3 million of cash and cash equivalents and $438.3$700.0 million available for borrowing under our revolving credit facility. These amounts excludefacility at our current commitment level. We expect decreases in our cash balance over the course of 2017 as we continue planned development in the core Wattenberg Field and further capital investment in our Delaware Basin assets.

We intend to continue to manage our liquidity position by a variety of means, including through the generation of cash flows from operations, investment in projects with attractive rates of return, protection of cash flows on a portion of our anticipated sales through the use of an additional $250 million availableactive commodity derivative hedging program, potential utilization of our borrowing capacity under our revolving credit facility, that will be available following the closing of the Delaware Basin Acquisition and may be available in other circumstances subjectwhen warranted, capital markets transactions from time to certain terms and conditions of the agreement. In October 2016, we completed the semi-annual redetermination of our revolving credit facility by the lenders, which resulted in the reaffirmation of the borrowing base at $700 million. We have elected to maintain the aggregate commitment level at $450 million until the closing of the Delaware Basin Acquisition. Cash and cash equivalents as of September 30, 2016 included approximately $392.3 million of proceeds from the issuance of the 2024 Senior Notes. If, however, the Delaware Basin Acquisition is not completed prior to or on December 31, 2016 (or in some circumstances by or on January 15, 2017), the $400 million principal amount of the 2024 Senior Notes is required to be redeemed with interest. If required, we will redeem the 2024 Senior Notes with available cash. With our current derivative position, available liquidity and expected cash flows from operations, we believe we have sufficient liquidity to allow us to fund our operations and the cash portion of the purchase price for the Delaware Basin Acquisition and execute our expected 2016 development program.

Operational Overview

During the ninesix months ended SeptemberJune 30, 2016,2017, we continued to execute our strategic plan to grow production while preserving our financial strength and liquidity. Through July 2016,During the second quarter of 2017, we ranoperated four automated drilling rigs in the Wattenberg Field. In August 2016, we decreased the number of automatedField and four drilling rigs runningin the Delaware Basin. Our drilling efficiency in the Wattenberg Field over the last two quarters has resulted in shorter drill cycle times; therefore, we expect to decrease our rig count to three rigs beginning in anticipationthe fourth quarter of higher working interests in wells drilled resulting from2017. Because of the aforementioned acreage exchange with Noble. Duringshorter drill times, the nine months ended September 30, 2016, we spud 107 horizontal wells and turned-in-line 121 horizontal wellsimpact of the reduced rig count on our expected turn-in-line count in the Wattenberg Field. We also participated in 11 gross, 2.8 net, horizontal non-operated wells that were spud and 24 gross, 5.0 net, horizontal non-operated wells which were turned-in-line. During the nine months ended September 30, 2016, we drilled and completed five wells in the Utica Shale, three of which were turned-in-line during the period. Of these three wells, oneField is an approximately 10,000 foot lateral well located in Guernsey County and two are approximately 6,000 foot lateral wells located in Washington County. We plan to turn-in-line the two remaining wells over the next several months.
2016 Operational Outlook

We expect our production for 2016expected to be at the high end or slightly exceed the 21.0 MMBoe to 22.0 MMBoe range disclosed earlierminimal in the year and our production rate for December 2016 to exceed 71,000 Boe per day, including the impact of expected production from2017. In the Delaware Basin, Acquisition, assuming the acquisition closesone rig contract expired in December 2016. Our revised 2016 capital forecast of $400 million to $420 million is focused on continuing to provide value-driven production growth by exploiting our substantial inventory of projects in the Wattenberg Field. Currently, excluding acquisition costs thatAugust 2017, and we expect to incurutilize three drilling rigs through the end of 2017. Our active drilling program in 2016 related to the Delaware Basin Acquisition, we expectin the first half of 2017 provided us with a degree of flexibility with respect to be near or slightly belowholding acreage in the low end ofarea on a near-term basis and allows us to shift immediate focus to improving drill cycle times and the expected rangeper well costs of our capital expenditures.

Colorado Ballot Initiative Update
The following tables summarizes our drilling and completion activity for the six months ended June 30, 2017:

During 2016, certain interest groups in Colorado opposed to oil and natural gas development generally, or hydraulic fracturing in particular, advanced various options for ballot initiatives aimed at significantly limiting or effectively preventing oil and natural gas development in the state of Colorado. Proponents of two such initiatives attempted to qualify the initiatives to appear on the ballot for the November 2016 election. On August 29, 2016, the Colorado Secretary of State issued a press release and statements of insufficiency of signatures, stating that the proponents of the proposals had failed to collect enough valid signatures to have the proposals included on the ballot.
One of the initiatives, which we refer to as the “local control” initiative, would have amended the state constitution to give city, town and county governments the right to regulate, or to ban, oil and gas development and production within their boundaries, notwithstanding rules and approvals to the contrary at the state level. This proposal was motivated in part by a decision of the Colorado Supreme Court earlier this year holding that local government restrictions on oil and gas activities are subject to preemption by state rules.
A second initiative, which we refer to as the “setback” initiative, would have amended the state constitution to require all new oil and gas development facilities to be located at least 2,500 feet away from any occupied structure or broadly defined “area of special concern,” including public and community drinking water sources, lakes, rivers, perennial or intermittent streams, creeks, irrigation canals, riparian areas, playgrounds, permanent sports fields, amphitheaters, public parks and public open space.
If implemented, the setback initiative would have effectively prohibited the vast majority of our planned future drilling activities in Colorado and would therefore have made it impossible to pursue our current development plans. The local control proposal would potentially have had a similar effect, depending on the nature and extent of regulations implemented by relevant local governmental authorities. Pursuant to the determination of the Colorado Secretary of State, these proposals will not appear on the November 2016 ballot. However, future proposals of this nature are possible.

Because substantially all of our current operations and reserves are located in Colorado, the risks we face with respect to such future proposals are greater than those of our competitors with more geographically diverse operations. Although we cannot predict the outcome of future ballot initiatives, statutes or regulatory developments, such developments could materially impact our results of operations, production and reserves.

Our in-process wells represent wells that are in the process of being drilled and/or have been drilled and are waiting to be fractured and/or for gas pipeline connection. Our drilled but uncompleted wells ("DUCs") are generally completed and turned in-line to sales within three to nine months of drilling. The majority of the in-process wells at each period end are DUCs, as we do not begin the completion process until the entire well pad is drilled. As we continue to monitor our capital investment and due to the efficiencies gained by our operating team in the Wattenberg Field, we expect that we will have an increase of approximately 25 wells in our in-process well count at December 31, 2017, as compared to December 31, 2016, resulting from faster than expected drill cycle times. All appropriate costs incurred through the end of the period have been capitalized, while the capital investment to complete the wells will be incurred in the period in which the wells are completed.

2017 Operational Outlook

Based on our revised timing and the estimated productivity of wells associated with our capital investment program, we currently believe that our 2017 production will be approximately 32 MMBoe. We expect that approximately 40 percent of our 2017 production will be crude oil and approximately 23 percent will be NGLs, for total liquids of approximately 63 percent. The anticipated percentage of production from NGLs has increased due to the success of field recovery efforts and improved yields by our third-party processors in the Wattenberg Field.

We expect our capital expenditures to be approximately $800 million in 2017, an estimate that we have increased to account for higher per well costs in the Delaware Basin and increases in the total expected number of wells to be spud in the Wattenberg Field during the year. We also added a third and fourth rig in the first quarter of 2017 in the Delaware Basin, which was sooner than initially contemplated in our budget, in order to protect certain leasehold positions and to create greater future operational flexibility. This flexibility as it relates to holding acreage in the Delaware Basin is particularly important given the volatility of commodity prices and potential further service cost increases in the Delaware Basin as it should allow us to adjust our drilling program to two rigs in this area if necessary for a period of time without risk of losing significant additional acreage.

Further, some additional capital investment has been included in our forecast for an anticipated Wattenberg Field acreage trade that would, if completed, increase our working interest in certain wells. The trade is expected to close in the second half of 2017.

Wattenberg Field. The 2017 investment forecast has been reduced to approximately $450 million in the Wattenberg Field with three rigs running in the fourth quarter of 2017. Approximately $445 million of our 2017 capital investment program is expected to be allocated to development activities, comprised of approximately $425 million for our operated drilling program and approximately $20 million for wells drilled and operated by others. The remainder of the

Wattenberg Field capital investment program is expected to be used for miscellaneous well equipment and capital projects. Wells in the Wattenberg Field typically have productive horizons at a depth of approximately 6,500 to 7,500 feet below the surface. In 2017, our revised investment forecast anticipates spudding approximately 155 and turning-in-line approximately 133 horizontal operated wells with lateral lengths of 4,000 to 10,000 feet.

Delaware Basin. Our 2017 investment forecast contemplates the operation of a three-rig program for the remainder of 2017 in the Delaware Basin. Total capital investment in the Delaware Basin has been increased to approximately $345 million, of which approximately $285 million is allocated to spud 24 and turn-in-line an estimated 20 wells. Expected per well drilling costs in the Delaware Basin have increased by approximately 15 to 20 percent during the second quarter of 2017 as compared to the first quarter of 2017, primarily due to higher costs of services and supplies and longer than anticipated drill cycle times.  To enhance our understanding of the geology in the Delaware Basin, we initiated various engineering studies on most of our Delaware Basin wells, including expanded depth pilot holes and logging/seismic services. These studies are providing important information to our operating team; however, they have come with additional unexpected costs. Additionally, mechanical issues have resulted in cost overruns for certain wells. Of the 20 planned turn-in-lines during 2017, 9 are expected to have extended laterals of approximately 10,000 horizontal feet with an estimated 70 to 75 completion stages per well. Similarly spaced completion stages are anticipated for the remaining 11 turn-in-lines. Wells in the Delaware Basin typically have productive horizons at a depth of approximately 9,000 to 11,000 feet below the surface. We plan to invest approximately $15 million for leasing, seismic, and technical studies with an additional $35 million for midstream-related projects including gas connections and surface location infrastructure. The remaining $10 million of the Delaware Basin capital investment program is expected to be used for non-operated capital projects.

We expect to incur costs associated with the purchase of seismic data and pilot hole exploratory work in the Delaware Basin, which will be accounted for as exploration, geologic, and geophysical expense. We estimate that this will result in approximately $5 million to $10 million of exploration expense in 2017.

Utica Shale. As a result of our evaluation of our strategic alternatives with respect to our Utica Shale position, we are working toward a divestiture of these properties during 2017. As of June 30, 2017, these assets did not meet the accounting criteria to be classified as held-for-sale; therefore, they continue to be included in properties and equipment on our condensed consolidated balance sheets. Subsequent to June 30, 2017, we engaged an investment banking group to assist in marketing the Utica properties for sale; therefore, these operations are expected to be classified as held-for-sale upon meeting the criteria for such classification in the third quarter of 2017.

In the Wattenberg Field, we rely on third-party midstream service providers to construct gathering, compression, and processing facilities to keep pace with our, and the overall field's natural gas production growth. From time to time, our production has been adversely affected by high line pressures on the gas gathering facilities, primarily due to higher ambient temperatures and increases in field-wide production volumes. In 2015, our primary midstream service provider added additional facilities which significantly reduced production constraints from late 2015 to mid-2017. However, we are

starting to experience higher line pressures due primarily to continued growth in field-wide production volumes. As a result, we anticipate higher production curtailments in the second half of 2017 and through most of 2018 until our primary midstream provider completes construction of an additional midstream plant and facilities. We believe that our 2017 production guidance range appropriately reflects the foreseeable impact of such higher gathering line pressures in the Wattenberg Field; however, such curtailment estimations may differ from the actual impact to production due to incremental uncertainties.

We continue work closely with our third party midstream providers in an effort to ensure adequate system capacity going forward in the Wattenberg Field. For example, we along with other operators, made a commitment with DCP Midstream, LP ("DCP") in December 2016 in connection with DCP's construction of additional gathering, compression, and processing facilities in the field. This expansion is expected to increase DCP's system capacity, assist in the control of line pressures on its natural gas gathering facilities, and reduce production curtailments in the field. We will be bound to the incremental volume requirements in this agreement on the first day of the calendar month after the actual in-service date of the plant, which is currently expected to occur in late 2018. The agreement imposes a baseline volume commitment and we are required for the first three years of the contract to guarantee a certain target profit margin to DCP on these volumes sold. Under our current drilling plans, we expect to meet both the baseline and incremental volume commitments, and we believe that the contractual target profit margin will be achieved without an additional payment from us. See footnote titled Commitments and Contingencies for additional details regarding the agreement. We also seek to negotiate construction of incremental projects designed to add capacity to our primary third-party midstream service provider's system between major new facility expansions.

The ultimate timing and availability of adequate infrastructure is not within our control and if our midstream service provider’s construction projects are delayed, we could experience higher gathering line pressures that may negatively impact our ability to fulfill our growth plans. Total system infrastructure performance may also be affected by a number of other factors, including potential additional increases in production from the Wattenberg Field.

For the three and nine months ended September 30, 2016, crude oil, natural gas and NGLs sales revenue increased compared to the three and nine months ended September 30, 2015 due to the following:

Production for the third quarter of 2016 was 6.0 million Boe, up from 4.3 million Boe in the third quarter of 2015. Year-to-date, production was 15.8 million Boe, up from 10.6 million Boe in the first nine months of 2015. Production increased as a result of continued drilling and completion activities as discussed in Operational Overview.

From time to time, our production has been adversely affected by high line pressures in the Wattenberg Field. Such pressures did not materially affect our production for the three or nine months ended September 30, 2016. We rely on our third-party midstream service providers to construct compression, gathering and processing facilities to keep pace with our production growth. We, along with other operators in the Wattenberg Field, continue to work closely with our third-party midstream providers in an effort to ensure adequate system capacity going forward. The timing and availability of adequate infrastructure, including potential line pressure impacts in 2017, is not within our control and may be affected by a number of factors, including potential increases in production from the Wattenberg Field and warmer than expected weather.Pricing

Crude Oil, Natural Gas and NGLs Pricing. Our results of operations depend upon many factors. Key factors particularlyare the price of crude oil, natural gas, and NGLs and our ability to market our production effectively. Crude oil, natural gas, and NGL prices are among the most volatilehave a high degree of all commodity prices. While the price ofvolatility and our realizations can change substantially. Our realized prices for crude oil, decreasednatural gas, and NGLs increased during the first ninethree and six months of 2016ended June 30, 2017 compared to the first ninethree and six months of 2015,ended June 30, 2016. NYMEX crude oil increased 6 percent and 27 percent, and natural gas prices increased during the third quarter of 201663percent and 61 percent, respectively, as compared to the first half of 2016 as the number of U.S. crude oil rigsthree and inventories declined. Natural gas prices decreased during the first nine months of 2016 when compared to the same prior year period. Although we did experience improved pricing by the end of the third quarter of 2016, due to an oversupply of nearly all domestic NGLs products, our average realized sales price for NGLs during the first nine months of 2016 reflected the same low levels seen during 2015. With the initiation of ethane exports and increased demand for NGLs, we are starting to see NGL prices trend upward.

Crude oil pricing is predominately driven by the physical market, supply and demand, financial markets and national and international politics. In the Wattenberg Field, crude oil is sold under various purchase contracts with monthly and longer term pricing provisions based on NYMEX pricing, adjusted for differentials. We have entered into longer term commitments ranging from three months to six months to deliver crude oil to competitive markets and these agreements have resulted in significantly improved deductions compared to the comparable period in 2015. We continue to pursue various alternatives with respect to oil transportation, particularlyended June 30, 2016. The realized NGL prices in the Wattenberg Field with a view toward further improving pricingare reflected in the tables below, net of the processing and limiting our use of trucking of production. We began delivering crude oiltransport costs that are embedded in accordance with our long term commitment to the White Cliffs Pipeline, LLC ("White Cliffs") pipeline in July 2015. This is one of several agreements we have entered into to facilitate deliveries ofapplicable percent-of-proceeds contracts, as are a portion of our crude oil to the Cushing, Oklahoma market. In addition, we have signed a long-term agreement for gatheringDelaware Basin NGL sales.

The following tables present weighted-average sales prices of crude oil, atnatural gas, and NGLs for the wellhead by pipeline from severalperiods presented. Our acquisitions of our padsassets in the Wattenberg Field, with a view toward minimizing truck traffic, increasing reliabilityDelaware Basin closed in December 2016; therefore, there is no comparative data for the three and reducing the overall physical footprint of our well pads. We began delivering crude oil into this pipeline during the fourth quarter of 2015 and the system was fully operational on certain wells in 2016. In the Utica Shale, crude oil and condensate is sold to local purchasers at each individual pad based on NYMEX pricing, adjusted for differentials, and is typically transported by the purchasers via truck to local refineries, rail facilities or barge loading terminals on the Ohio River.six months ended June 30, 2016:

Amounts may not recalculate due to markets, availability of pipeline capacity and supply and demand relationships in that region or locality. The price we receive for our natural gas produced in the Wattenberg Field is based on CIG and local utility prices, adjusted for certain deductions, while natural gas produced in the Utica Shale is based on TETCO M-2 pricing. We anticipate that the significant Appalachian pipeline differentials that impact our Utica Shale natural gas will continue through the remainder of 2016 and into 2017.

Our price for NGLs produced in the Wattenberg Field is based on a combination of prices from the Conway hub in Kansas and Mt. Belvieu in Texas where this production is marketed. The NGLs produced in the Utica Shale are sold based on month-to-month pricing to various markets. While NGL prices had been declining, we have seen a stabilization of prices in 2016.rounding.

Our crude oil, natural gas, and NGLs sales are recorded under either the “net-back” or "gross" method of accounting, depending upon the related purchase agreement. We use the "net-back"net-back method of accounting for natural gas and NGLs, as well as the majority of our crude oil production from the Wattenberg Field, for all of our crude oil, NGLs, and a portion of our natural gas in the Delaware Basin, and for crude oil from the Utica Shale, as the majority of the purchasers of these commodities also provide transportation, gathering, and processing services. In these situations, the purchaser pays us proceeds based on a percent of the proceeds, or have fixed our sales price at index less specified deductions. We sell our commodities at the wellhead, or what is equivalent to the wellhead in situations where we gather multiple wells into larger pads, and collect a price and recognize revenues based on the wellhead sales price, as transportation and processing costs downstream of the wellhead are incurred by the purchaser and reflectedtherefore embedded in the wellhead price. The net-back method results in the recognition of a net sales price that is lower than the indices for which the production is based because the operating costs and profit of the midstream facilities are embedded in the net price we earn.

wellhead price. The net-back method results in the recognition of a sales price that is below the indices for which the production is based. We use the "gross"gross method of accounting for Wattenberg Field crude oil delivered through certain pipelines, a portion of our natural gas in the White Cliffs and Saddle Butte pipelinesDelaware Basin, and for natural gas and NGLs sales related to production from the Utica Shale, as the purchasers do not provide transportation, gathering or processing services.services as a function of the price we earn. Rather, we contract separately with midstream providers for the applicable transport and processing based on a per unit basis. Under this method, we recognize revenues based on the gross selling price and recognize transportation, gathering, and processing expenses. As a result of the White Cliffs and Saddle Butte agreements, during the nine months ended September 30, 2016, our Wattenberg Field crude oil average sales price increased approximately $1.24 per barrel relative to the benchmark price because we recognized the costs for transportation on the White Cliffs and Saddle Butte pipelines as an increase in transportation expense, rather than as a deduction from revenues.

Lease Operating Expenses

Lease operating expenses duringAs discussed above, we enter into agreements for the three months ended September 30, 2016 increased $0.2 million as compared tosale and transportation, gathering and processing of our production, the three months ended September 30, 2015, primarily due to increasesterms of $0.8 millionwhich can result in variances in the per unit realized prices that we receive for payroll and employee benefits and $0.8 million for leased compressors to address increases in line pressure. These increases were partially offset by decreases of $1 million related to mechanical integrity testing of wells and $0.2 million in environmental project costs. Lease operating expenses during the nine months ended September 30, 2016 increased $0.3 million as compared to the nine months ended September 30, 2015, primarily due to increases of $1.6 million for payroll and employee benefits, $1.1 million for leased compressors to address line pressure issues and $1 million for various other lease operating expenses. These increases were partially offset by decreases of $2.6 million for environmental project costs and $0.7 million for plugging and abandonment costs. Lease operating expenses per Boe decreased 27% and 32% to $2.33 and $2.73 during the three and nine months ended September 30, 2016, respectively, compared to $3.20 and $4.04 during the three and nine months ended September 30, 2015, respectively. The significant decreases in lease operating expense per Boe were the result of production growth of 39% and 49%, respectively.

Production Taxes

Production taxes are directly related toour crude oil, natural gas and NGLs sales. The $4.1 million increase in production taxes during the three months ended September 30, 2016 compared to the three months ended September 30, 2015 was primarilyNGLs.

For crude oil, the average NYMEX prices shown below are based upon average daily prices throughout each month and our natural gas and NGLs sales, as well as higher severance tax ratesaverage NYMEX pricing is based upon projectedfirst-of-the-month index prices as this is the method used to sell the majority of each of these commodities pursuant to terms of the respective sales revenue. The $6.5 million increase in production taxes duringagreements.  For NGLs, we use the nine months ended September 30, 2016 compared to the nine months ended September 30, 2015 was primarily related to the 19% increase inNYMEX crude oil natural gas and NGLs sales,price as well as higher severance tax rates due to higher projected sales revenue coupled with a decrease in ad valorem tax credits available from 2015 production due to depressed commodity pricing in 2015.

Transportation, Gathering and Processing Expenses

reference for presentation purposes. The $1.1 million increase inaverage realized price before transportation, gathering, and processing expenses duringshown in the three months ended September 30, 2016 compared to the three months ended September 30, 2015 was mainly attributable to oil transportation costs on the Saddle Butte pipeline as we began delivering crude oil on this pipeline in December 2015. The $7 million increase in transportation, gathering and processing expenses during the nine months ended September 30, 2016, compared to the nine months ended September 30, 2015, was mainly attributable to oil transportation costs on the White Cliffs and Saddle Butte pipelines as we began delivering crude oil on these pipelines in July 2015 and December 2015, respectively. We expect to continue to incur these oil transportation costs pursuant totable below represents our long-term transportation agreements.approximate composite per barrel price for NGLs.

Commodity Price Risk Management, Net

We use variouscommodity derivative instruments to manage fluctuations in crude oil, natural gas, and crude oilNGLs prices. We have in place a variety of collars, fixed-price swaps, and basis swaps on a portion of our estimated crude oil, natural gas, and crude oilpropane production. Because we sell all of our crude oil, natural gas, and crude oilNGLs production at prices similarrelated to the indexes inherent in our underlying derivative instruments, adjusted for certain fees and surcharges stipulated in the applicable sales agreements, we ultimately realize a price, before contract fees,value related to our collars of no less than the floor and no more than the ceiling and, forceiling. For our commodity swaps, we ultimately realize the fixed price value related to our swaps, less deductions.the swaps. See Note 4,the footnote titled Commodity Derivative Financial Instruments, to our condensed consolidated financial statements included elsewhere in this report for a detailed presentation of our derivative positions as of SeptemberJune 30, 2016.2017.

Commodity price risk management, net, includes cash settlements upon maturity of our derivative instruments and the change in fair value of unsettled commodity derivatives related to our crude oil, and natural gas, and propane production. Commodity price risk management, net, does not include derivative transactions related to our natural gas marketing, which are included in sales fromother income and costother expenses.

Net settlements of commodity derivative instruments are based on the difference between the crude oil, natural gas, marketing. See Note 3, Fair Value of Financial Instruments, and Note 4, Derivative Financial Instruments, to our condensed consolidated financial statements included elsewhere in this report for additional details of our derivative financial instruments.

Net settlements are primarily the result of crude oil and natural gaspropane index prices at maturitythe settlement date of our commodity derivative instruments compared to the respective strike prices. Netprices contracted for the settlement months that were established at the time we entered into the commodity derivative transaction. The net change in fair value of unsettled commodity derivatives is comprised of the net assetvalue increase or decrease in the beginning-of- periodbeginning-of-period fair value of commodity derivative instruments that settled during the period, and the net change in fair value of unsettled commodity derivatives during the period or from inception of any new contracts entered into during the applicable period. The corresponding impact of settlement of the commodity derivative instruments that settled during the period is included in net settlements for the period as discussed above. Netperiod. The net change in fair value of unsettled commodity derivatives during the period is primarily related to shifts in the crude oil, and natural gas, and NGLs forward curves and changes in basis index pricing. See Note 4, Derivative Financial Instruments, to our condensed consolidated financial statements included elsewhere in this report for a detailed description of net settlements on our various derivatives.certain differentials.

Net settlements of commodity derivatives decreased for the three and six months ended June 30, 2017 as compared to the three and six months ended June 30, 2016.  We entered into agreements for the derivative instruments that settled throughout 2016 prior to commodity prices becoming depressed in late 2014.  Substantially all of these higher-value agreements had settled by the end of 2016.  Net settlements for the three and six months ended June 30, 2017 reflect derivative instruments entered into since 2015, which more closely approximate recent realized prices.  Based upon the forward strip pricing at June 30, 2017, we expect that settlements will continue to be substantially lower in 2017 on a relative basis as compared to those in 2016.

Lease Operating Expenses

Lease operating expenses improved to $2.50 per Boe and $2.72 per Boe during the three and six months ended June 30, 2017, respectively, compared to $2.63 per Boe and $2.97 per Boe during the three and six months ended June 30, 2016, respectively. The improvement in lease operating expense per Boe was predominately driven by production growth of 54 percent and 50 percent during the three and six months ended June 30, 2017, respectively, which was partially offset by higher lease operating expense of $4.88 per Boe and $5.53 per Boe in the Delaware Basin during the three and six months ended June 30, 2017, respectively.

Aggregate lease operating expenses during the three months ended June 30, 2017 increased $6.4 million as compared to the three months ended June 30, 2016, of which $4.5 million related to our recently-acquired properties in the Delaware Basin. The increase of $6.4 million is primarily due to increases of $2.4 million for payroll and employee benefits related to increases in headcount for 2017 as compared to 2016, $1.0 million for water hauling, $1.0 million related to compressor rentals, and $0.5 million for workover projects. These increases were partially offset by a decrease of $0.4 million in environmental remediation costs.

Aggregate lease operating expenses during the six months ended June 30, 2017 increased $10.8 million as compared to the six months ended June 30, 2016, of which $8.4 million related to our recently-acquired properties in the Delaware Basin. The increase of $10.8 million is primarily due to increases of $4.2 million for payroll and employee benefits related to increases in headcount for 2017 as compared to 2016, $1.8 million for water hauling, $1.7 million for workover projects, and $1.7 million related to compressor rentals. These increases were partially offset by a decrease of $1.6 million in environmental remediation costs. We expect continued increases in our headcount through the remainder of 2017 as we grow our Delaware

Basin production base and production team. We expect much of this increased cost of personnel will be offset by increases in our production.

Production Taxes

Production taxes are comprised mainly of severance tax and ad valorem tax and are directly related to crude oil, natural gas, and NGLs sales and are generally assessed as a percentage of net revenues. There are a number of adjustments to the statutory rates for these taxes based upon certain credits that are determined based upon activity levels and relative commodity prices from year-to-year. The $9.0 million and $17.3 million increases in production taxes during the three and six months ended June 30, 2017, respectively, compared to the three and six months ended June 30, 2016 were primarily related to the 93 percent and 117 percent increases in crude oil, natural gas, and NGLs sales, and an increase in our effective tax rate to approximately seven percent for the three and six months ended June 30, 2017 as compared to five percent for the three and six months ended June 30, 2016.

Transportation, Gathering, and Processing Expenses

Transportation,gathering, and processing expenses increased $2.0 million and $3.9 million during the three and six months ended June 30, 2017, respectively, compared to the three and six months ended June 30, 2016. The primary drivers of these increases were $1.2 million and $2.2 million increases in oil transportation costs due to increased volumes delivered through a pipeline in the Wattenberg Field and increases of $0.7 million and $1.4 million related to natural gas gathering operations in our recently acquired properties in the Delaware Basin, respectively. When feasible, we use pipelines in the Wattenberg Field to deliver crude oil to the market in an effort to decrease field truck traffic and air emissions. Transportation, gathering, and processing expenses per Boe improved to $0.81 and $0.84 for the three and six months ended June 30, 2017, respectively, compared to $0.86 and $0.87 for the three and six months ended June 30, 2016, respectively.

Impairment of Properties and Equipment
    
Impairment of proved and unproved properties. Amounts represent the retirement or expiration of certain leases that are no longer part of our development plan or that we are not able to extend prior to termination of the lease. Deterioration of commodity prices or other operating circumstances could result in additional impairment charges as such a change could decrease the number of wells drilled in future periods.

During the three months ended June 30, 2017, we impaired certain unproved Delaware Basin leasehold positions totaling $27.0 million that expired during the three months ending June 30, 2017, or are projected to expire between June 30, 2017 and December 31, 2017.  Subsequent to closing the acquisitions in the Delaware Basin, it was determined that development of certain acreage tracts would not meet our internal expectations for acceptable rates of return due to a combination of weakening commodity prices; higher per well development and operational costs; and updated technical analysis.  As a result, we allowed or expect to allow certain acreage to expire, and in other circumstances we were unable to obtain necessary lease term extensions.

The following table sets forth the major components of our impairment of properties and equipment expense:

General and Administrative Expense

Impairment of provedGeneral and unproved properties. Due to a significant decline in commodity prices and a decrease in net-back realizations in the third quarter of 2015, we experienced a triggering event that required us to assess our crude oil and natural gas propertiesadministrative expense increased $6.0 million for possible impairment. As a result of our assessment, we recorded an impairment charge during the three months ended SeptemberJune 30, 2015 of $150.3 million to write-down our Utica Shale proved and unproved properties. Of this impairment charge, $24.7 million was recorded to write-down certain capitalized well costs on our Utica Shale proved producing properties. Additionally,2017 as a result of the outlook for future commodity prices at that time, we recorded an impairment charge of $125.6 million to write-down all of our Utica Shale lease acquisition costs and pad development costs for pads not in production. Future deterioration of commodity prices could result in additional impairment charges to our crude oil and natural gas properties.

Amortization of individually insignificant unproved properties. Amounts relate to insignificant leases that were subject to amortization. The decreases in amortization during the three and nine months ended September 30, 2016 compared to the three and nine months ended SeptemberJune 30, 2015 were due2016, of which $2.9 million is related to the Delaware Basin. The increase of $6.0 million was primarily attributable to increases of $1.5 million in payroll and employee benefits related to an impairmentincrease in the third quarter of 2015 that significantly reduced the carrying value of our Utica Shale leases.

Land and buildings. The impairment chargeheadcount for the nine months ended September 30, 2016 represents the excess of the carrying value over the estimated fair value, less the cost to sell, of a field operating facility in Greeley, Colorado, and 12 acres of land located adjacent to our Bridgeport, West Virginia, regional headquarters. The fair values of these assets were determined based upon estimated future cash flows from unrelated third-party bids, a Level 3 input.2017

Depreciation, Depletion and Amortization Expense

Crude oil and natural gas properties. DD&A expense related to crude oil and natural gas properties is directly related to proved reserves and production volumes. DD&A expense related to crude oil and natural gas properties was $112.1$124.4 million and $314.4$232.2 million for the three and ninesix months ended SeptemberJune 30, 20162017, respectively, compared to $79.8$106.1 million and $203.5$202.4 million for the three and ninesix months ended SeptemberJune 30, 2015. 2016, respectively. Through June 30, 2017, our capital investment in the Delaware Basin has not yet resulted in the addition of related proved reserves, resulting in an elevated DD&A expense rate for the three and six months ended June 30, 2017.

The period-over-period change in DD&A expense related to crude oil and natural gas properties was primarily due to the following:

Provision for Uncollectible Notes Receivable

DuringIn the first quarter of 2016, we recorded a provision for uncollectible notes receivable of $44.7 million to impair two third-party notes receivable whose collection was not reasonably assured. DuringAs described in the three months ended September 30, 2016, we subsequently collected a $0.7 million promissory note and reversed the related provision and allowance for uncollectible notes receivable. See Note 3,footnote titled Fair Value of Financial Instruments - Notes Receivable, in April 2017, we signed a definitive agreement and simultaneously closed on the sale of one of the associated notes receivable to our condensed consolidated financial statements included elsewherean unrelated third-party. Accordingly, we reversed $40.2 million of the provision for uncollectible notes receivable during the three months ended June 30, 2017, since all cash was collected in this reportApril 2017 from the sale of the Promissory Note.

The effective income tax rates are based onupon a full year forecasted pre-tax lossincome for the year adjusted for state tax, permanent differences and discrete items of tax.differences. The forecasted full year effective income tax rate has been applied to the quarter-to-date pre-tax lossincome, resulting in aan income tax benefitexpense for the period. Because the estimate of full-year income or loss may change from quarter to quarter, the effective income tax rate for any particular quarter may not have a meaningful relationship to pre-tax income or loss for the quarter or the actual annual effective income tax rate that is determined at the end of the year.

Our deferred The effective income tax liability at Septemberrates for the three and six months ended June 30, 2016 decreased $99.12017 include discrete income tax benefits of $0.2 million compared to December 31, 2015.

Financial Condition, Liquidity and Capital Resources

Historically, ourOur primary sources of liquidity have beenare cash flows from operating activities, our revolving credit facility, proceeds raised in debt and equity capital market transactions, and asset sales. For the ninesix months ended SeptemberJune 30, 2016,2017, our primary sources of liquidity were the net proceeds received from the March 2016 public offering of our common stock of $296.6 million, net proceeds from the Securities Issuances of approximately $1.1 billion, and net cash flows from operating activities of $360.8were $263.2 million. We used a portion of the net proceeds of the March 2016 common stock offering to repay all amounts then outstanding on our revolving credit facility and the principal amount owed upon the maturity of the 2016 Convertible Notes in May 2016 and retained the remainder for general corporate purposes. The net proceeds from the Securities Issuances are expected to be used to fund a portion of the purchase price of the Delaware Basin Acquisition (see Note 6, Pending Acquisition), to pay related fees and expenses and for general corporate purposes.

Our primary source of cash flows from operating activities is the sale of crude oil, natural gas, and NGLs. Fluctuations in our operating cash flows are substantiallyprincipally driven by commodity prices and changes in our production volumes. Commodity prices have historically been volatile and we manage this volatility through our use of derivative instruments. We enter into commodity derivative instruments with maturities of no greater than five years from the date of the instrument. TheOur revolving credit agreement imposes limits on the amount of our production we can hedge, and we may choose not to hedge the maximum amounts permitted. Therefore, we may still have significant fluctuations in our cash flows from operating activities due to the remaining non-hedged portion of our future production. Given current commodity prices and our hedge position, we expect that positive net settlements on our derivative positions will continue to be a significant positive component of our 2016 cash flows from operations. As of September 30, 2016, the fair value of our derivatives was a net asset of $33.5 million. Based on the forward pricing strip at September 30, 2016, we would expect positive net settlements totaling approximately $39.3 million during the fourth quarter of 2016. However, based upon our current hedge position and assuming currentforward strip pricing inas of June 30, 2017, and thereafter our derivatives may no longernot be a significant source of cash flow and may result in cash outflows. For the nine months ended September 30, 2016 and 2015, net settled derivatives comprised approximately 47% and 57%, respectively, of our cash flows from operating activities. See Part I, Item 3, Quantitative and Qualitative Disclosures about Market Risk, included elsewhere in this report for additional information regarding our derivatives positions by year of maturity.near term.

Our working capital fluctuates for various reasons, including, but not limited to, changes in the fair value of our commodity derivative instruments and changes in our cash and cash equivalents due to our practice of utilizing excess cash to reduce the outstanding borrowings under our revolving credit facility. At June 30, 2017, we had working capital of $65.6 million compared to $129.2 million at December 31, 2016. The decrease in working capital as of June 30, 2017 is primarily the result of a decrease in cash and cash equivalents of $41.8 million related to capital investment exceeding operating cash flows

our revolving credit facility. At September 30, 2016, we had working capital of $1,148.8 million compared to $30.7 million at December 31, 2015. Theandan increase in working capital asaccounts payable of September 30, 2016 is primarily the result of$86.2 million related to increased development and exploration activity, which was partially offset by an increase in the net fair value of our unsettled commodity derivative instruments of $86.8 million.

Our cash and cash equivalents related to the Securities Issuances and the repayment of the 2016 Convertible Notes in May 2016, offset in part by a decrease in the fair value of unsettled derivatives.

In recent periods, including the first nine months of 2016, we have been able to access borrowings under our revolving credit facility and to obtain proceeds from the issuance of securities. We ended September 2016 with cash and cash equivalents of $1,197.7were $202.3 million at June 30, 2017 and availability under our revolving credit facility of $438.3was $700.0 million, providing for a total liquidity position of $1,636$902.3 million comparedas of June 30, 2017. We anticipate that our capital investments will exceed our cash flows from operating activities in 2017, resulting in cash and cash equivalents estimated to $402.2be between $100 million atto $150 million as of December 31, 2015. These amounts exclude an additional $250 million available2017.

Based on our expected cash flows from operations, our cash and cash equivalents and availability under our revolving credit facility, that will be available following the closing of the Delaware Basin Acquisition and may be available in other circumstances subject to certain terms and conditions of the agreement. The increase in liquidity of $1,233.8 million, or 306.8%, during the nine months ended September 30, 2016 was primarily attributable to net cash flows from operating activities of $360.8 million and net cash flows from financing activities of $1,284.8 million (including proceeds from the Securities Issuances), offset in part by cash paid for capital expenditures of $353.7 million. Our liquidity position was reduced by the cash payment of approximately $115 million upon the maturity of our 2016 Convertible Notes in May 2016. With our current derivative position, liquidity position and expected cash flows from operations, we believe that we have sufficient capital to fund our planned activities during 2017. Our liquidity was further augmented by the cash portion$40.2 million of proceeds received in the second quarter of 2017 from the sale of the purchase price forPromissory Note, as described previously.

Our revolving credit facility is a borrowing base facility and availability under the Delaware Basin Acquisitionfacility is subject to redetermination each May and November, based upon a quantification of our planned drilling operations forproved reserves at each June 30 and December 31, respectively.

In March 2015, we filed an automatic shelf registration statement on Form S-3 with the SEC. Effective upon filing, the shelf provides for the potential sale of an unspecified amount of debt securities, common stock or preferred stock, either separately or represented by depository shares, warrants or purchase contracts, as well as units that may include any of these securities or securities of other entities. The shelf registration statement is intended to allow us to be proactive in our ability to raise capital and to have the flexibility to raise such funds in one or more offerings should we perceive market conditions to be favorable. Pursuant to this shelf registration, we sold approximately four million shares of our common stock in March 2015 in an underwritten public offering at a price to us of $50.73 per share, approximately six million shares of our common stock in March 2016 in an underwritten public offering at a price to us of $50.11 per share and, in September 2016, approximately nine million shares of our common stock in an underwritten public offering at a price to us of $61.51 per share and $200 million principal amount of convertible notes in an underwritten offering at par.

In September 2016,May 2017, we entered into a ThirdFifth Amendment to the Third Amended and Restated Credit Agreement. The amendment, among other things, amends the revolving credit facility to permit the completionreflect an increase of the Delaware Basin Acquisition and, effective upon closing of the acquisition, adjusts the interest rate payable on amounts borrowed under the facility and increases the aggregate commitments under the facility from $450 million to $700 million (with the borrowing base remaining atfrom $700 million). The maturitymillion to $950 million. We have elected to maintain a $700 million commitment level as of the date of this report. In addition, the Fifth Amendment made changes to certain of the covenants in the existing agreement as well as other administrative changes.

Amounts borrowed under the revolving credit facility bear interest at either an alternate base rate option or a LIBOR option as defined in the revolving credit facility plus an applicable margin, depending on the percentage of the commitment that has been utilized. As of June 30, 2017, the applicable margin is May 2020. 1.25 percent for the alternate base rate option or 2.25 percent for the LIBOR option, and the unused commitment fee is 0.50 percent.

We had no balance outstanding balance on our revolving credit facility as of SeptemberJune 30, 2016. While2017. In May 2017, we have addedreplaced our $11.7 million irrevocable standby letter of credit that we held in favor of a third-party transportation service provider to secure a firm transportation obligation with a $9.3 million deposit, which is classified as restricted cash and expect to continue to add producing reserves throughis included in other assets on the condensed consolidated balance sheet. As of June 30, 2017, the available funds under our drilling operations, the effect of any such reserve additionsrevolving credit facility was $700 million based on our borrowing base could be offset by other factors including, among other things, a prolonged period of depressed commodity prices or regulatory pressure on lenders to reduce their exposure to exploration and production companies.elected commitment level.
In October 2016, we entered into the Fourth Amendment to the Third Amended and Restated Credit Agreement. The amendment, among other things, reaffirmed our borrowing base at $700 million and made certain other immaterial modifications to the existing agreement, including an increase in the amount we can hedge of our future production.
Our revolving credit facility contains financial maintenance covenants. The covenants require that we maintain:maintain (i) a leverage ratio defined as total debt of less than 4.254.0 times the trailing 12 months earnings before interest, taxes, depreciation, depletion and amortization, change in fair value of unsettled commodity derivatives, exploration expense, gains (losses) on sales of assets and other non-cash extraordinary or non-recurring gains (losses) ("EBITDAX") and (ii) an adjusted current ratio of at least 1.0 to 1.0:1.0. Our adjusted current ratio is adjusted by eliminating the impact on our current assets and liabilities of recording the fair value of crude oil and natural gas commodity derivative instruments. Additionally, available borrowings under our revolving credit facility are added to the current asset calculation and the current portion of our revolving credit facility debt is eliminated from the current liabilities calculation. Effective upon closing of the Delaware Basin Acquisition, the maximum leverage ratio will be modified to a maximum of 4.00 to 1.00. At SeptemberJune 30, 2016,2017, we were in compliance with all debt covenants, as defined by the revolving credit agreement, with a 2.2 times debt to EBITDAXleverage ratio of 1.9 and a 8.9 to 1.0 current ratio.ratio of 3.3. We expect to remain in compliance throughout the next year.12-month period.

The indentures governing our 20242022 Senior Notes and 20222024 Senior Notes contain customary restrictive covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to: (a) incur additional debt including under our revolving credit facility, (b) make certain investments or pay dividends or distributions on our capital stock or purchase, redeem, or retire capital stock, (c) sell assets, including capital stock of our restricted subsidiaries, (d) restrict the payment of dividends or other payments by restricted subsidiaries to us, (e) create liens that secure debt, (f) enter into transactions with affiliates, and (g) merge or consolidate with another company. At SeptemberJune 30, 2016,2017, we were in compliance with all covenants and expect to remain in compliance throughout the next year.12-month period.

Cash Flows

Operating Activities. Our net cash flows from operating activities are primarily impacted by commodity prices, production volumes, net settlements from our commodity derivative positions, operating costs, and general and administrative expenses. Cash flows from operating activities increased by $77.8$65.4 million for the ninesix months ended SeptemberJune 30, 20162017 compared to the ninesix months ended SeptemberJune 30, 2015,2016, primarily due to increases in crude oil, natural gas and NGLs sales of $52.5 million, net settlements from our derivative positions of $5.4$217.1 million and crude oil, and

thean increase in changes in assets and liabilities of $45.2$12.3 million related to the timing of cash payments and receipts. These increases were offset in part by a decrease in commodity derivative settlements of $107.6 million and increases in production taxes of $17.3 million, interest expense of $16.5 million, lease operating expenses of $10.8 million, and general and administrative expenses of $16.8 million, transportation, gathering and processing expenses of $7 million and production taxes of $6.5$9.5 million. The key components for the changes in our cash flows provided by operating activities are described in more detail in Results of Operations above.

Adjusted cash flows from operations, a non-U.S. GAAP financial measure, increased $32.6$53.0 million during the ninesix months ended SeptemberJune 30, 2016,2017 compared to the ninesix months ended SeptemberJune 30, 2015.2016. The increase was primarily due to the same factors mentioned above for changes in cash flows provided by operating activities, without regard to timing of cash payments and receipts of assets and liabilities.  Adjusted EBITDA,EBITDAX, a non-U.S. GAAP financial measure, decreasedincreased by $16.6$150.4 million during the ninesix months ended SeptemberJune 30, 20162017, compared to the ninesix months ended SeptemberJune 30, 2015.2016. The decreaseincrease was primarily the result of recording a provision for uncollectible notes receivable of $44 million and the increases in transportation, gathering and processing expenses of $7 million, production taxes of $6.5 million and general and administrative expense of $16.8 million, offset in part by increases in crude oil, natural gas and NGLs sales of $52.5$217.1 million, the recording of a provision for uncollectible notes receivable of $44.7 million during the six months ended June 30, 2016, and the reversal of a provision for uncollectible notes receivable of $40.2 million during the six months ended June 30, 2017.  These increases were partially offset by a decrease in commodity derivative settlements of $107.6 million and net settlements from our derivative positionsincreases in production taxes of $5.4$17.3 million, lease operating expenses of $10.8 million, and general and administrative expenses of $9.5 million. See Reconciliation of Non-U.S. GAAP Financial Measures, below, for a more detailed discussion of non-U.S. GAAP financial measures.

Investing Activities. Because crude oil and natural gas production from a well declines rapidly in the first few years of production, we need to continue to commit significant amounts of capital in order to maintain and grow our production and replace our reserves. If capital is not available or is constrained in the future, we will be limited to our cash flows from operations and liquidity under our revolving credit facility as the sources for funding our capital expenditures.investments.

Cash flows from investing activities primarily consist of the acquisition, exploration, and development of crude oil and natural gas properties, net of dispositions of crude oil and natural gas properties. Net cash used in investing activities of $448.8$299.1 million during the ninesix months ended SeptemberJune 30, 20162017, was primarily related to cash utilized for our drilling operations, including completion activities of $353.7$334.4 million, purchases of short-term investments of $49.9 million, and a $100$9.3 million deposit towardwith a third-party transportation service provider for surety of an existing firm transportation obligation previously secured by a letter of credit.  Partially offsetting these investments was the cash portionreceipt of approximately $49.9 million related to the sale of short-term investments, $40.2 million from the sale of the purchase pricePromissory Note, and $5.4 million related to post-closing settlements of the Delaware Basin Acquisition.properties acquired in 2016.

Financing Activities. Net cash from financing activities for the ninesix months ended SeptemberJune 30, 2016 increased2017 decreased by approximately $1,091.5$147.2 million compared to the ninesix months ended SeptemberJune 30, 2015. Net cash from2016. Certain capital markets and financing activities of $1,284.8 million for the nine months ended September 30,occurred in 2016 was primarily related to the $855.1including $296.6 million received from the issuancesan issuance of our common stock, $392.3 million of proceeds from issuance of the 2024 Senior Notes and $194 million of proceeds from issuance of the 2021 Convertible Notes,stock. These amounts were partially offset by the $115$115.0 million payment of principal amounts owed upon the maturity of the 2016 Convertible Notes and net payments of approximately $37$37.0 million to pay down amounts borrowed under our revolving credit facility.

Drilling Activity
The following table presents our net developmental drilling activity for the periods shown. Productive wells consist of wells spud, turned-in-line and producing during the period.

Commitments and Contingencies

See Note 11,the footnote titled Commitments and Contingencies to the accompanying condensed consolidated financial statements included elsewhere in this report.



Recent Accounting Standards

See Note 2,the footnote titled Summary of Significant Accounting Policies, to the accompanying condensed consolidated financial statements included elsewhere in this report.

Recent Regulatory Developments

On May 2, 2017, in response to an incident in Firestone, Colorado, the Colorado Oil & Gas Conservation Commission (“COGCC”) issued a Notice to Operators (the “Notice”). Among other things, the Notice included requirements for all operators of oil and gas wells in Colorado to inspect all existing flowlines and pipelines located within 1,000 feet of a building unit; inspect any abandoned flowlines or pipelines, regardless of distance to ensure proper abandonment; and test integrity of all connected flowlines. Additional regulations or mandates from the COGCC or other regulators related to this matter are expected to arise.

We timely complied with both phases of the Notice. We have an existing Flowline Integrity Management Program to inspect all Denver-Julesburg Basin wells and related pipelines on an annual basis, and will continue to engage in this process.

Critical Accounting Policies and Estimates

The preparation of the accompanying condensed consolidated financial statements in conformity with U.S. GAAP required management to use judgment in making estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses.

There have been no significant changes to our critical accounting policies and estimates or in the underlying accounting assumptions and estimates used in these critical accounting policies from those disclosed in the condensed consolidated financial statements and accompanying notes contained in our 20152016 Form 10-K filed with the SEC on February 22, 2016.28, 2017.

Reconciliation of Non-U.S. GAAP Financial Measures

We use "adjusted cash flows from operations," "adjusted net income (loss)" and "adjusted EBITDA,EBITDAX," non-U.S. GAAP financial measures, for internal management reporting, when evaluating period-to-period changes and, in some cases, providing public guidance on possible future results. Beginning in 2017, we have included non-cash stock-based compensation and exploration, geologic and geophysical expense to our reconciliation of adjusted EBITDAX calculation.  In prior periods, we included adjusted EBITDA, a non-U.S. GAAP financial measure that did not include these adjustments.  We have elected to disclose Adjusted EBITDAX rather than Adjusted EBITDA in this report and other public disclosures because we believe it is more comparable to similar metrics presented by others in the industry. All prior periods have been conformed for comparability of this information. These measures are not measures of financial performance under U.S. GAAP and should be considered in addition to, not as a substitute for, net income (loss) or cash flows from operations, investing or financing activities, and should not be viewed as liquidity measures or indicators of cash flows reported in accordance with U.S. GAAP. The non-U.S. GAAP financial measures that we use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-U.S. GAAP financial measures in order to help our investors more meaningfully evaluate and compare our future results of operations to our previously reported results of operations. We strongly encourage investors to review our financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

Adjusted cash flows from operationsoperations. . We define adjusted cash flows from operations as the cash flows earned or incurred from operating activities, without regard to changes in operating assets and liabilities. We believe it is important to consider adjusted cash flows from operations, as well as cash flows from operations, as we believe it often provides more transparency into what drives the changes in our operating trends, such as production, prices, operating costs, and related operational factors, without regard to whether the related asset or liability was received or paid during the same period. We also use this measure because the timing of cash received from our assets, cash paid to obtain an asset or payment of our obligations has generally been only a timing issue from one period to the next as we have not had significant accounts receivable collection problems, nor been unable to purchase assets or pay our obligations. See the condensed consolidated statements of cash flows in the accompanying condensed consolidated financial statements included elsewhere in this report.

Adjusted net income (loss). We define adjusted net income (loss) as net income (loss), plus loss on commodity derivatives, less gain on commodity derivatives, and net settlements on commodity derivatives, each adjusted for tax effect. We believe it is important to consider adjusted net income (loss), as well as net income (loss). We believe this measure often provides more transparency into our operating trends, such as production, prices, operating costs, net settlements from

derivatives, and related factors, without regard to changes in our net income (loss) from our mark-to-market adjustments resulting from net changes in the fair value of unsettled derivatives. Additionally, other items which are not indicative of future results may be excluded to clearly identify operating trends.

Adjusted EBITDA.EBITDAX. We define adjusted EBITDAEBITDAX as net income (loss), plus loss on commodity derivatives, interest expense, net of interest income, income taxes, impairment of properties and equipment, exploration, geologic, and geophysical expense, depreciation, depletion and amortization expense, and accretion of asset retirement obligations, and non-cash stock-based compensation, less gain on commodity derivatives and net settlements on commodity derivatives. Adjusted EBITDAEBITDAX is not a measure of financial performance or liquidity under U.S. GAAP and should be considered in addition to, not as a substitute for, net income (loss), and should not be considered an indicator of cash flows reported in accordance with U.S. GAAP. Adjusted EBITDAEBITDAX includes certain non-cash costs incurred by the Companyus and does not take into account changes in operating assets and liabilities. Other companies in our industry may calculate adjusted EBITDAEBITDAX differently than we do, limiting its usefulness as a comparative measure. We believe adjusted EBITDAEBITDAX is relevant because it is a measure of our operational and financial performance, as well as a measure of our liquidity, and is used by our management, investors, commercial banks, research analysts, and others to analyze such things as:

operating performance and return on capital as compared to our peers;
financial performance of our assets and our valuation without regard to financing methods, capital structure, or historical cost basis;
our ability to generate sufficient cash to service our debt obligations; and
the viability of acquisition opportunities and capital expenditure projects, including the related rate of return.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market-Sensitive Instruments and Risk Management

We are exposed to market risks associated with interest rate risks, commodity price risk and credit risk. We have established risk management processes to monitor and manage these market risks.

Interest Rate Risk

Changes in interest rates affect the amount of interest we earn on our interest bearing cash, cash equivalents, and restricted cash accounts and the interest we pay on borrowings under our revolving credit facility. Our 2021 Convertible Notes, 2024 Senior Notes, and 2022 Senior Notes have fixed rates, and therefore near-term changes in interest rates do not expose us to risk of earnings or cash flow loss; however, near-term changes in interest rates may affect the fair value of our fixed-rate debt.

As of SeptemberJune 30, 2016,2017, our interest-bearing deposit accounts included money market accounts, certificates of deposit, and checking and savings accounts with various banks. The amount of our interest-bearing cash, cash equivalents, and restricted cash as of SeptemberJune 30, 20162017 was $1,167$201.5 million with a weighted-average interest rate of 0.3%.0.9 percent. Based on a sensitivity analysis of our interest-bearing deposits as of SeptemberJune 30, 20162017 and assuming we had $1,167$201.5 million outstanding throughout the period, we estimate that a 1%one percent increase in interest rates would have increased interest income for the ninesix months ended SeptemberJune 30, 20162017 by approximately $8.7$1.0 million.

As of SeptemberJune 30, 2016,2017, we had no outstanding balance on our revolving credit facility.
    
Commodity Price Risk

We are exposed to the potential risk of loss from adverse changes in the market price of crude oil, natural gas, natural gas basis, and NGLs. Pursuant to established policies and procedures, we manage a portion of the risks associated with these market fluctuations using commodity derivative instruments. These instruments help us predict with greater certainty the effective crude oil, and natural gas, natural gas basis, and propane prices we will receive for our hedged production. We believe that our commodity derivative policies and procedures are effective in achieving our risk management objectives.

Credit Risk

Credit risk represents the loss that we would incur if a counterparty fails to perform its contractual obligations. We attempt to reduce credit risk by diversifying our counterparty exposure and entering into transactions with high-quality counterparties. When exposed to significant credit risk, we analyze the counterparty’s financial condition prior to entering into an agreement, establish credit limits and monitor the appropriateness of those limits on an ongoing basis. We monitor the creditworthiness of significant counterparties through our credit committee, which utilizes a number of qualitative and quantitative tools to assess credit risk and takes mitigative actions if deemed necessary. While we believe that our credit risk analysis and monitoring procedures are reasonable, no amount of analysis can assure performance by our counterparties.

Our Oiloil and Gas Explorationgas exploration and Production segment'sproduction business's crude oil, natural gas, and NGLs sales are concentrated with a few predominately large customers. This concentrates our credit risk exposure with a small number of large customers.

Amounts due to our Gas Marketing segmentgas marketing business are from a diverse group of entities, including major upstream and midstream energy companies, financial institutions, and end-users in various industries. The underlying operations of these entities are geographically concentrated in the same region, which increases the credit risk associated with this business. As natural gas prices continue to remain depressed, certain third-party producers underrelating to our Gas Marketing segment have begun andgas marketing business continue to experience financial distress, which has led to certain contractual defaults and litigation; however, to date, we have had no material counterparty default losses. We have initiated several legal actions for breach of contract, collection and related claims against certain third-party producers that are delinquent in their payment obligations, which have to date resulted in onetwo default judgment.judgments. We expect this trend to continue for this segment.business.

A group of 42 independent West Virginia natural gas producers has filed a lawsuit in Marshall County, West Virginia, naming Dominion, certain entities affiliated with Dominion, and RNG as defendants, alleging various contractual, fiduciary and related claims against the defendants, all of which are associated with firm transportation contracts entered into by plaintiffs and relating to pipelines owned and operated by Dominion and its affiliates. RNG and Dominion have removed the case to the U.S. District Court for the Northern District of West Virginia and are preparing pre-trial pleadings, including an answer to the compliant and a motion to dismiss the case. At this time, RNG is unable to estimate any potential damages associated with the claims, but believes the complaint is without merit and intends to vigorously pursue its defense.

We primarily use financial institutions which are lenders in our revolving credit facility as counterparties for our derivative financial instruments. Disruption in the credit markets, changes in commodity prices and other factors may have a significant adverse impact on a number of financial institutions. To date, we have had no material counterparty default losses from our commodity derivative financial instruments. See Note 4, the footnote titled Commodity Derivative Financial Instruments, to our condensed consolidated financial statements included elsewhere in this report for more detail on our commodity derivative financial instruments.

Disclosure of Limitations

Because the information above included only those exposures that existed at SeptemberJune 30, 2016,2017, it does not consider those exposures or positions which could arise after that date. As a result, our ultimate realized gain or loss with respect to interest rate and commodity price fluctuations will depend on the exposures that arise during the period, our commodity price risk management strategies at the time, and interest rates and commodity prices at the time.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of SeptemberJune 30, 2016,2017, we carried out an evaluation under the supervision and with the participation of management, including the Chief Executive Officer and the Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15(e) and 15d-15(e).

Based on the results of this evaluation, the Chief Executive Officer and the Principal Financial Officer concluded that our disclosure controls and procedures were effective as of SeptemberJune 30, 2016.2017.

Changes in Internal Control over Financial Reporting

During the three months ended SeptemberJune 30, 2016,2017, we made no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

PART II
ITEM 1. LEGAL PROCEEDINGS

Information regarding ourFrom time to time, we are a party to various legal proceedings in the ordinary course of business. We are not currently a party to any litigation that we believe would have a materially adverse effect on our business, financial condition, results of operations, or liquidity.

Environmental

Due to the nature of the natural gas and oil industry, we are exposed to environmental risks. We have various policies and procedures to minimize and mitigate the risks from environmental contamination. We conduct periodic reviews and simulated drills to identify changes in our environmental risk profile. Liabilities are recorded when environmental damages resulting from past events are probable and the costs can be foundreasonably estimated. Except as discussed herein, we are not aware of any environmental claims existing as of June 30, 2017, which have not been provided for or would otherwise have a material impact on our financial statements; however, there can be no assurance that current regulatory requirements will not change or that unknown past non-compliance with environmental laws will not be discovered on our properties. Accrued environmental liabilities are recorded in Note 10, Commitments and Contingencies – Litigation, to ourother accrued expenses on the condensed consolidated financial statements included elsewherebalance sheets.

In August 2015, we received a Clean Air Act Section 114 Information Request (the "Information Request") from the U.S. Environmental Protection Agency ("EPA"). The Information Request sought, among other things, information related to the design, operation, and maintenance of our Wattenberg Field production facilities in the Denver-Julesburg Basin of Colorado. The Information Request focuses on historical operation and design information for 46 of our production facilities and asks that we conduct sampling and analyses at the identified 46 facilities. We responded to the Information Request with the requested data in January 2016.
In addition, in December 2015, we received a Compliance Advisory pursuant to C.R.S. 25-7-115(2) from the Colorado Department of Public Health and Environment's (“CDPHE”) Air Quality Control Commission's Air Pollution Control Division alleging that we failed to design, operate, and maintain certain condensate collection, storage, processing, and handling operations to minimize leakage of volatile organic compounds at 65 facilities consistent with applicable standards under Colorado law.

For more than a year, we held a series of meetings with the EPA, Department of Justice (“DOJ”) and CDPHE on the above matters. On June 26, 2017, the DOJ on behalf of the EPA and the State of Colorado filed a complaint against us based
Table of contents


on the above matters. We continue to schedule meetings with these agencies in working toward a resolution of the matters. The ultimate outcome related to these combined actions is not known at this report.time.

Action Regarding Firm Transportation Contracts
In June 2016, a group of 42 independent West Virginia natural gas producers filed a lawsuit in Marshall County, West Virginia, naming Dominion Transmission, Inc. ("Dominion"), certain entities affiliated with Dominion, and our subsidiary RNG as defendants, alleging various contractual, fiduciary and related claims against the defendants, all of which are associated with firm transportation contracts entered into by plaintiffs and relating to pipelines owned and operated by Dominion and its affiliates. The case has been transferred to the Business Court Division of the Circuit Court of Marshall County, West Virginia, and the parties are awaiting that court's ruling on previously-filed pre-trial pleadings. RNG is unable to estimate any potential damages associated with the claims, but believes the complaint is without merit and intends to vigorously pursue its defenses.


ITEM 1A. RISK FACTORS

We face many risks. Factors that could materially adversely affect our business, financial condition, operating results, or liquidity and the trading price of our common stock are described under Item 1A, Risk Factors, of our 20152016 Form 10-K. This information should be considered carefully, together with other information in this report and other reports and materials we file with the SEC.

There have been no material changes from the risk factors previously disclosed in our 20152016 Form 10-K, except for the following:

If completed, the Delaware Basin Acquisition may not achieve its intended results and may result in us assuming unanticipated liabilities. To date, we have conducted only limited diligence regarding the assets and liabilities we would assume in the transaction.

We entered into the Delaware Basin Acquisition agreements with the expectation that the acquisition would result in various benefits, growth opportunities and synergies. Achieving the anticipated benefits of the transaction is subject to a number of risks and uncertainties. For example, under the acquisition agreements, we have the opportunity to conduct customary environmental and title due diligence following the execution of the agreements, but our diligence efforts to date have been limited. As a result, we may discover title defects or adverse environmental or other conditions of which we are currently unaware. Environmental, title and other problems could reduce the value of the properties to us, and, depending on the circumstances, we could have limited or no recourse to the sellers with respect to those problems. We would assume substantially all of the liabilities associated with the acquired properties and would be entitled to indemnification in connection with those liabilities in only limited circumstances and in limited amounts. We cannot assure you that such potential remedies will be adequate for any liabilities we incur, and such liabilities could be significant. In addition, certain of the properties to be acquired are subject to consents to assign and preference rights. If all applicable waivers cannot be obtained, we may not be able to acquire certain properties as originally contemplated and our expected benefits of the acquisition may be adversely affected. Further, the acquisition agreements allow the sellers to include a specified amount of additional leases in the transaction, which would increase the purchase price. Also, it is uncertain whether our existing operations and the acquired properties and assets can be integrated in an efficient and effective manner.

As with other acquisitions, the success of the Delaware Basin Acquisition depends on, among other things, the accuracy of our assessment of the reserves and drilling locations associated with the acquired properties, future oil, NGL and natural gas prices and operating costs and various other factors. These assessments are necessarily inexact. As a result, we may not recover the purchase price for the acquisition from the sale of production from the property or recognize an acceptable return from such sales. See "-Risks Related to Our Business and the Industry-Acquisitions of properties are subject to the uncertainties of evaluating recoverable reserves and potential liabilities, including environmental uncertainties" in our 2015 Form 10-K. Although the properties to be acquired are subject to many of the risks and uncertainties to which our business and operations are subject, risks associated with the Delaware Basin Acquisition in particular include those associated with our ability to operate efficiently in an area where we have no current operations, the significant size of the transaction relative to our existing operations, the fact that a substantial majority of the properties to be acquired are undeveloped and the additional indebtedness we have incurred in connection with the acquisition. We also expect that pursuing our future development plans for the properties to be acquired will require
Table of contents


capital in excess of our projected cash flows from operations for some period of time beginning in 2017, which may increase our need for external financing.

In addition, the integration of operations following the Delaware Basin Acquisition will require substantial attention from our management and other personnel, which may distract their attention from our day-to-day business and operations and prevent us from realizing benefits from other opportunities. Completing the integration process may be more expensive than anticipated, and we cannot assure you that we will be able to effect the integration of these operations smoothly or efficiently or that the anticipated benefits of the transaction will be achieved.

The reserves, production and drilling locations estimates with respect to the properties to be acquired in the Delaware Basin Acquisition may differ materially from the actual amounts.

The reserves, production and drilling locations estimates with respect to the properties to be acquired in the Delaware Basin Acquisition are based on our analysis of historical production data, assumptions regarding capital expenditures and anticipated production declines. Such analysis is based, in significant part, on data provided by the sellers. We cannot assure you that these estimates are accurate. After such data is further reviewed by us and our independent engineers, the actual reserves, production and number of viable drilling locations may differ materially from our expectations.

We have incurred significant transaction-related costs in connection with the Delaware Basin Acquisition and the related financing transactions.

We have incurred a number of significant transaction-related costs associated with the Delaware Basin Acquisition and the related financing transactions. We continue to assess the magnitude of these costs and additional unanticipated costs, including costs incurred in the integration of the properties to be acquired, which may be significant.

Failure to complete the Delaware Basin Acquisition could negatively affect our stock price as well as our business and financial results.

Closing of the Delaware Basin Acquisition is subject to a number of conditions. If the Delaware Basin Acquisition is not completed, we will be subject to a number of risks, including but not limited to the following:

We must pay costs related to the acquisition including, among others, legal, accounting and financial advisory fees, whether the acquisition is completed or not.

In some circumstances set forth in the acquisition agreements, we could be required to forfeit the $100 million aggregate deposit we made at the time the agreements were executed.

We may experience negative reactions from the financial markets.

We could be subject to litigation related to the failure to complete the acquisition.
