SRC ENERGY INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1.Organization and Summary of Significant Accounting Policies

Organization:  SRC Energy Inc. is an independent oil and natural gas company engaged in the acquisition, exploration, development, and production of oil, natural gas, and natural gas liquids ("NGLs"), primarily in the Denver-Julesburg Basin ("D-J Basin") of Colorado. The Company’s common stock is listed and traded on the NYSE American under the symbol "SRCI."

Basis of Presentation:  The Company operates in one business segment, and all of its operations are located in the United States of America.

At the directive of the Securities and Exchange Commission ("SEC") to use "plain English" in public filings, the Company will use such terms as "we," "our," "us," or the "Company" in place of SRC Energy Inc. When such terms are used in this manner throughout this document, they are in reference only to the corporation, SRC Energy Inc., and are not used in reference to the Board of Directors, corporate officers, management, or any individual employee or group of employees.

The condensed consolidated financial statements include the accounts of the Company, including its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.  The Company prepares its condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“US GAAP”).

Interim Financial Information:  The unaudited condensed consolidated interim financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the SEC as promulgated in Rule 10-01 of Regulation S-X.  The condensed consolidated balance sheet as of December 31, 20172018 was derived from the Company's annual consolidated financial statements included within its Annual Report on Form 10-K for the year ended December 31, 20172018 as filed with the SEC on February 21, 2018.20, 2019.  Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such SEC rules and regulations.  The Company believes that the disclosures included are adequate to make the information presented not misleading and recommends that these condensed financial statements be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2017.2018.

In our opinion, the unaudited condensed consolidated financial statements contained herein reflect all adjustments, consisting solely of normal recurring items, which are necessary for the fair presentation of the Company's financial position, results of operations, and cash flows on a basis consistent with that of its prior audited financial statements.  However, the results of operations for interim periods may not be indicative of results to be expected for the full fiscal year.

Major Customers: The Company sells production to a small number of customers as is customary in the industry. Customers representing 10% or more of our oil, natural gas, and NGL revenues (“major customers”) for each of the periods presented are shown in the following table:
 Three Months Ended September 30, Nine Months Ended September 30, Three Months Ended March 31,
Major Customers 2018 2017 2018 2017 2019 2018
Company A 23% 30% 13% 27% 28% 31%
Company B 21% 27% 19% 26% 25% *
Company C 14% 13% 28% 15% 20% 19%
Company D 14% * 11% * * 13%
Company E 14% * 16% *
* less than 10%

Based on the current demand for oil and natural gas, the availability of other buyers, the multiple contracts for sales of our products, and the Company having the option to sell to other buyers if conditions warrant, the Company believes that the loss of our existing customers or individual contracts would not have a material adverse effect on us. Our oil and natural gas production is a commodity with a readily available market, and we sell our products under many distinct contracts. In addition, there are several oil and natural gas purchasers and processors within our area of operations to whom our production could be sold.
 

Accounts receivable consist primarily of receivables from oil, natural gas, and NGL sales and amounts due from other working interest owners who are liable for their proportionate share of well costs. The Company typically has the right to withhold future revenue disbursements to recover outstanding joint interest billings on outstanding receivables from joint interest owners.

Customers with balances greater than 10% of total receivable balances as of each of the periods presented are shown in the following table (these companies do not necessarily correspond to those presented above):
 As of As of As of As of
Major Customers September 30, 2018 December 31, 2017 March 31, 2019 December 31, 2018
Company A 23% 26% 24% 15%
Company B 16% 16% 14% 12%
Company C 14% 23% 14% 12%
Company D 14% * 11% 13%
Company E * 11% 10% *
* less than 10%

The Company operates exclusively within the United States of America, and except for cash and cash equivalents, all of the Company’s assets are utilized in, and all of our revenues are derived from, the oil and gas industry.

Recently Adopted Accounting Pronouncements:

In May 2014,February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2014-09, “Revenue from ContractsNo. 2016-02, Leases (Topic 842), followed by other related ASUs that provided targeted improvements and additional practical expedient options (collectively “ASC 842”). ASC 842 requires lessees to recognize right-of-use (“ROU”) assets and lease payment liabilities on the balance sheet for leases representing the Company’s right to use the underlying assets over the lease term. Each lease that is recognized on the balance sheet will be classified as either finance or operating, with Customers (Topic 606)” (“ASU 2014-09”), which establishes a comprehensive new revenuesuch classification affecting the pattern and classification of expense recognition standard designed to depictin the transferconsolidated statements of goods or services to a customer in an amount that reflectsoperations and presentation within the consideration the entity expects to receive in exchange for those goods or services. In March 2016, the FASB released certain implementation guidance through ASU 2016-08 (collectively with ASU 2014-09, the "Revenue ASUs") to clarify principal versus agent considerations. The Revenue ASUs allow for the usestatements of either the full or modified retrospective transition method, and the standard became effective for annual reporting periods beginning after December 15, 2017 including interim periods within that period. cash flows.

The Company adopted the guidanceASC 842 on January 1, 2019 using the modified retrospective methodmethod. The Company elected as part of its adoption to also use the optional transition methodology whereby previously reported periods continue to be reported in accordance with historical accounting guidance for leases that were in effect for those prior periods. Policy elections and practical expedients that the effective dateCompany has implemented as part of adopting ASC 842 include (a) excluding from the balance sheet leases with terms that are less than or equal to one year, (b) for all existing asset classes that contain both lease and non-lease components, combining these components together and accounting for them as a single lease component, (c) the package of practical expedients, which among other things, allows the Company to avoid reassessing contracts that commenced prior to adoption that were properly evaluated under legacy GAAP, and (d) excluding land easements, which were not accounted for under the previous leasing guidance, that existed or expired before adoption of ASC 842. The scope of ASC 842 does not apply to leases used in the exploration or use of minerals, oil, and natural gas.

The Company's adoption of ASC 842 resulted in an increase in other assets, accounts payable and accrued expenses, and other liabilities line items on the accompanying condensed consolidated balance sheets as a result of the additional ROU assets and related lease liabilities. Upon adoption on January 1, 2018. The2019, the Company did not record a cumulative-effect adjustmentrecognized approximately $2.4 million in ROU assets and $4.3 million in liabilities for its operating leases. There was no cumulative effect to the opening balance of retained earnings as no adjustment was necessary. Theupon the adoption of the Revenue ASUs did not impact net income or cash flows.this guidance. See Note 14 for the new disclosures required by the Revenue ASUs.ASC 842.

Recently Issued Accounting Pronouncements:   We evaluate the pronouncements of various authoritative accounting organizations to determine the impact of new accounting pronouncements on us. 

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" ("ASU 2016-02"), which establishes a comprehensive new lease standard designed to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous US GAAP. ASU 2016-02 is effective for public businesses for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We are currently evaluating the impact of the adoption of this standard on our financial statements.

There were various updates recently issued by the FASB, most of which represented technical corrections to the accounting literature or application to specific industries and are not expected to a have a material impact on our reported financial position, results of operations, or cash flows.

Change in estimate: Production taxes are comprised primarily of two elements: severance tax and ad valorem tax. During the three months ended March 31, 2019, the Company reduced its estimate for 2018 severance taxes. When preparing the 2018 severance tax return, the credit for ad valorem taxes was greater than originally estimated, resulting in a reduction of 2018 severance taxes. Based on this analysis, the Company's prior year accrual was reduced, resulting in an approximate $7.9 million reduction to our production taxes, which increased our operating income for the three months ended March 31, 2019 by a corresponding amount, or $0.03 per basic and diluted common share.

The Company periodically reviews its oil and gas properties to determine if the carrying value of such assets exceeds estimated fair value. For proved producing and non-producing properties, the Company performs a ceiling test each quarter to determine whether there has been an impairment to its capitalized costs. At September 30,March 31, 2019 and December 31, 2018, and 2017, the calculated value of the ceiling limitation exceeded the carrying value of our oil and gas properties subject to the test, and no impairments were necessary.

Capitalized Overhead: A portion of the Company’s overhead expenditures are directly attributable to acquisition, exploration, and development activities.  Under the full cost method of accounting, these expenditures, in the amounts shown in the table below, were capitalized in the full cost pool (in thousands):

3.    Acquisitions

September 2018 Acquisition and Swap
In September 2018, the Company completed the purchase of vertical and horizontal wells in the Greeley-Crescent development area in Weld County, Colorado for $64.1 million in cash and the assumption of certain liabilities for a total purchase price of $96.8 million. This purchase was contemplated as part of the GCII Acquisition discussed below in "‑December 2017 Acquisition." The effective date of this part of the transaction was September 1, 2018. The transaction was accounted for as an asset acquisition under ASC 805, Business Combinations, which requires the acquired assets and liabilities to be recorded at cost on the acquisition date of September 27, 2018. 

In September 2018, we completed a trade with another party of approximately 2,500 net acres. This transaction further enhances the contiguous nature of the Company's acreage position.

August 2018 Acquisition

In August 2018, the Company completed the purchase of leasehold acreage and associated non-operated production for $37.6 million in cash and the assumption of certain liabilities for a total purchase price of $38.0 million. The acreage increased our working interest in existing operations and planned wells. The transaction was accounted for as an asset acquisition under ASC 805, Business Combinations, which requires the acquired assets and liabilities to be recorded at cost on the acquisition date of August 3, 2018.

December 2017 Acquisition

In December 2017, the Company completed the purchase of approximately 30,200 net acres and the associated non-operated production in the Greeley-Crescent development area in Weld County, Colorado for $576.4 million in cash and the assumption of certain liabilities for a total purchase price of $577.5 million ("GCII Acquisition"). The purchase price has been allocated as $60.8 million to proved oil and gas properties and $516.7 million to unproved oil and gas properties. The effective date of this part of the transaction was November 1, 2017. The transaction was accounted for as an asset acquisition under ASC 805, Business Combinations, which requires the acquired assets and liabilities to be recorded at cost on the acquisition date of December 15, 2017.

Capitalized costs of proved oil and gas properties are depleted quarterly using the units-of-production method based on a depletion rate, which is calculated by comparing production volumes for the quarter to estimated total reserves at the beginning of the quarter.


5.4.Asset Retirement Obligations

Upon completion or acquisition of a well, theThe Company recognizes obligations for its oil and natural gas operations for anticipated costs to remove and dispose of surface equipment, remediate the well, and reclaim the drilling site to its original use.  The estimated present value of such obligations is determined using several assumptions and judgments about the ultimate settlement amounts, inflation factors, credit-adjusted discount rates, timing of settlement, and changes in regulations.  Changes in estimates are reflected in the obligations as they occur.  If the fair value of a recorded asset retirement obligation changes, a revision is recorded to both the asset retirement obligation and the capitalized asset retirement cost.  The following table summarizes the changes in asset retirement obligations associated with the Company's oil and gas properties (in thousands):

6.5.Revolving Credit Facility

On April 2, 2018, the Company entered into a second amended and restated credit agreement (the “Restated Credit Agreement”) with certain banks and other lenders. The Restated Credit Agreement provides a revolving credit facility (sometimes referred to as the "Revolver") and a $25 million swingline facility with a maturity date of April 2, 2023. The Revolver is available for working capital for exploration and production operations, acquisitions of oil and gas properties, and general corporate purposes and to support letters of credit. At September 30, 2018,March 31, 2019, the terms of the Revolver provided for up to $1.5 billion in borrowings, an aggregate elected commitment of $450$500 million, and a borrowing base limitation of $550$650 million. As of September 30, 2018March 31, 2019 and December 31, 2017,2018, the outstanding principal balance was $115.0 million$195.0 million. At March 31, 2019 and nil, respectively. At September 30,December 31, 2018, the Company had no letters of credit issued. The average annual interest rate for borrowings during the three months ended March 31, 2019 was 4.5%.

In October 2018,April 2019, the lenders under the Revolver completed their semi-annual redetermination of our borrowing base. The borrowing base was increased from $550$650 million to $650$700 million, and we increased our aggregate elected commitment from $450$500 million to $500$550 million.

Interest under the Revolver accrues monthly at a variable rate.  For each borrowing, the Company designates its choice of reference rates, which can be either the Prime Rate plus a margin or LIBOR plus a margin. The interest rate margin, as well as other bank fees, varies with utilization of the Revolver. The average annual interest rate for borrowings during the nine months ended September 30, 2018 and 2017 was 4.0% and 3.3%, respectively.

Certain of the Company’s assets, including substantially all of its producing wells and developed oil and gas leases, have been designated as collateral under the Restated Credit Agreement. The amount available to be borrowed is subject to scheduled redeterminations on a semi-annual basis. If certain events occur or if the bank syndicate or the Company so elects in certain circumstances, an unscheduled redetermination could be undertaken.

The Restated Credit Agreement contains covenants that, among other things, restrict the payment of dividends, and limit our overall commodity derivative position to a maximum position that varies over 5 years as a percentage of the projected production from proved developed producing or total proved reserves as reflected in the most recently completed reserve report.
Furthermore, the Restated Credit Agreement requirespositions, and require the Company to maintain compliance with certain financial and liquidity ratio covenants. In particular, the Company must not (a) permit its ratio of total funded debt to EBITDAX, as defined in the agreement, to be greater than or equal to 4.0 to 1.0 as of the last day of any fiscal quarter or (b) permit its ratio of current assets to current liabilities, each as defined in the agreement, to be less than 1.0 to 1.0 as of the last day of any fiscal quarter. As of September 30, 2018,March 31, 2019, the most recent compliance date, the Company was in compliance with these loan covenants and expects to remain in compliance throughout the next 12-month period.

7.6.Notes Payable

2025 Senior Notes

In November 2017, the Company issued $550 million aggregate principal amount of 6.25% Senior Notes due 2025 (the "2025 Senior Notes") in a private placement to qualified institutional buyers. The maturity for the payment of principal is December 1, 2025. Interest on the 2025 Senior Notes accrues at 6.25% and began accruing on November 29, 2017.. Interest is payable on June 1 and December 1 of each year, beginning on June 1, 2018.year. The 2025 Senior Notes were issued pursuant to an indenture dated as of November 29, 2017. The net proceeds from the sale of the 2025 Senior Notes were $538.1 million after deductions of $11.9 million for expenses and underwriting discounts and commissions. The associated expenses and underwriting discounts and commissions are amortized using the effective interest method at an effective interest rate of 6.6%.The net proceeds were used to fund the GCII Acquisition as discussed further in Note 3, to repay our previously outstanding senior notes due 2021, and to pay off the outstanding Revolver balance.
At any time prior to December 1, 2020, the Company may redeem all or a part of the 2025 Senior Notes at a redemption price equal to 100% of the principal amount plus an Applicable Premium (as defined in the Indenture) and accrued and unpaid interest.  On and after December 1, 2020, the Company may redeem all or a part of the 2025 Senior Notes at a redemption price equal to a specified percentage of the principal amount of the redeemed notes (104.688% for 2020, 103.125% for 2021, 101.563%for 2022, and 100% for 2023 and thereafter, during the twelve-month period beginning on December 1 of each applicable year), plus accrued and unpaid interest. Additionally, prior to December 1, 2020, the Company can, on one or more occasions, redeem up to35%of the principal amount of the 2025 Senior Notes with all or a portion of the net cash proceeds of one or more Equity Offerings (as defined in the Indenture) at a redemption price equal to106.25% of the principal amount of the redeemed notes, plus accrued and unpaid interest, subject to certain conditions.


The Indenture contains covenants that restrict the Company’s ability and the ability of certain of its subsidiaries to, among other restrictions and limitations: (i) incur additional indebtedness; (ii) incur liens; (iii) pay dividends; (iv) consolidate, merge, or transfer all or substantially all of its or their assets; (v) engage in transactions with affiliates; or (vi) engage in certain restricted business activities.  These covenants are subject to a number of exceptions and qualifications. The indenture governing the 2025 Senior Notes provides that, in certain circumstances, the notes will be guaranteed by one or more subsidiaries of the Company, in which case such guarantee would be made on a full and unconditional and joint and several senior unsecured basis. As of March 31, 2019, none of the Company's subsidiaries met the criteria outlined within the Indenture to be considered a guarantors of the 2025 Senior Notes.

As of September 30, 2018,March 31, 2019, the most recent compliance date, the Company was in compliance with these covenants and expects to remain in compliance throughout the next 12-month period.

8.7.Commodity Derivative Instruments

The Company has entered into commodity derivative instruments as described below. Our commodity derivative instruments may include but are not limited to "collars," "swaps," and "put" positions. Our derivative strategy, including the volumes and commodities covered and the relevant strike prices, is based in part on our view of expected future market conditions and our analysis of well-level economic return potential. In addition, our use of derivative contracts is subject to stipulations set forth in the Revolver.

The Company may, from time to time, add incremental derivatives to cover additional production, restructure existing derivative contracts, or enter into new transactions to modify the terms of current contracts in order to realize the current value of the Company’s existing positions. The Company does not enter into derivative contracts for speculative purposes.

The use of derivatives involves the risk that the counterparties to such instruments will be unable to meet the financial terms of such contracts. The Company’s derivative contracts are currently with seven counterparties. Five of the counterparties are lenders in the Restated Credit Agreement. The Company has netting arrangements with the counterparties that provide for the offset of payables against receivables from separate derivative arrangements with the counterparty in the event of contract termination. The derivative contracts may be terminated by a non-defaulting party in the event of default by one of the parties to the agreement.

The Company’s commodity derivative instruments are measured at fair value and are included in the accompanying condensed consolidated balance sheets as commodity derivative assets or liabilities. Unrealized gains and losses are recorded based on the changes in the fair values of the derivative instruments. Both the unrealized and realized gains and losses are recorded in the condensed consolidated statements of operations. The Company’s cash flow is only impacted when the actual settlements under commodity derivative contracts result in it making or receiving a payment to or from the counterparty. Actual cash settlements can occur at either the scheduled maturity date of the contract or at an earlier date if the contract is liquidated prior to its scheduled maturity. These settlements under the commodity derivative contracts are reflected as operating activities in the Company’s condensed consolidated statements of cash flows.

Offsetting of Derivative Assets and Liabilities

As of September 30, 2018March 31, 2019 and December 31, 2017,2018, all derivative instruments held by the Company were subject to enforceable master netting arrangements held by various financial institutions. In general, the terms of the Company’s agreements provide for offsetting of amounts payable or receivable between the Company and the counterparty, at the election of either party, for transactions that occur on the same date and in the same currency. The Company’s agreements also provide that, in the event of an early termination, each party has the right to offset amounts owed or owing under that and any other agreement with the same counterparty. The Company’s accounting policy is to offset these positions in its condensed consolidated balance sheets.

The following table provides a reconciliation between the net assets and liabilities reflected on the accompanying condensed consolidated balance sheets and the potential effect of master netting arrangements on the fair value of the Company’s derivative contracts (in thousands):

Credit Related Contingent Features

As of September 30, 2018,March 31, 2019, five of the seven counterparties to the Company's derivative instruments were members of the Company’s credit facility syndicate. The Company’s obligations under the credit facility and its derivative contracts are secured by liens on substantially all of the Company’s producing oil and gas properties. The agreement with the sixth and seventh counterparties, which are not lenders under the credit facility, is unsecured and does not require the posting of collateral.

9.8.Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosure, establishes a hierarchy for inputs used in measuring fair value for financial assets and liabilities that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.  Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company.  Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability based on the best information available in the circumstances.  The hierarchy is broken down into three levels based on the reliability of the inputs as follows:

Level 1: Quoted prices available in active markets for identical assets or liabilities;
Level 2: Quoted prices in active markets for similar assets and liabilities that are observable for the asset or liability; and
Level 3: Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash or valuation models.


The financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.

The Company’s non-recurring fair value measurements include unproved properties,measurement includes asset retirement obligations, and purchase price allocations for the fair value of assets and liabilities acquired through certain asset acquisitions. Please referobligations. Refer to Notes 2, 3, and 5Note 4 for further discussion of unproved properties, asset acquisitions, and asset retirement obligations, respectively.

The acquisition of a group of assets in certain asset acquisitions requires fair value estimates for assets acquired and liabilities assumed.  The fair value of assets and liabilities acquired is calculated using a net discounted cash flow approach for the proved producing, proved undeveloped, probable, and possible properties. The discounted cash flows are developed using the income approach and are based on management’s expectations for the future.  Unobservable inputs include estimates of future oil and natural gas production from the Company’s reserve reports, commodity prices based on the NYMEX forward price curves as of the date of the estimate (adjusted for basis differentials), estimated operating and development costs, and a risk-adjusted discount rate (all of which are designated as Level 3 inputs within the fair value hierarchy). For unproved properties, the fair value is determined using market comparables.obligations.

The Company determines the estimated fair value of its asset retirement obligations by calculating the present value of estimated cash flows related to plugging and abandonmentreclamation liabilities using Level 3 inputs. The significant inputs used to calculate such liabilities include estimates of costs to be incurred, the Company’s credit-adjusted risk-free rate, inflation rates, and estimated dates of abandonment.reclamation. The asset retirement liability is accreted to its present value each period, and the capitalized asset retirement cost is depleted as a component of the full cost pool using the units-of-production method. See Notes 3 and 5Note 4 for additional information.

The following table presents the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis by level within the fair value hierarchy (in thousands):

Commodity Derivative Instruments

The Company determines its estimate of the fair value of commodity derivative instruments using a market approach based on several factors, including quoted market prices in active markets, quotes from third parties, the credit rating of each counterparty, and the Company’s own credit standing. In consideration of counterparty credit risk, the Company assessed the possibility of whether the counterparties to its derivative contracts would default by failing to make any contractually required payments. The Company considers the counterparties to be of substantial credit quality and believes that they have the financial resources and willingness to meet their potential repayment obligations associated with the derivative transactions. At September 30, 2018,March 31, 2019, derivative instruments utilized by the Company consist of swaps and collars. The oil and natural gas derivative markets are highly active. Although the Company’s derivative instruments are valued based on several factors including public indices, the instruments themselves are traded with third-party counterparties. As such, the Company has classified these instruments as Level 2.

Fair Value of Financial Instruments

The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, commodity derivative instruments (discussed above), notes payable, and credit facility borrowings. The carrying values of cash and cash equivalents, accounts receivable, and accounts payable are representative of their fair values due to their short-

termshort-term maturities. Due to the variable interest rate paid on the credit facility borrowings, the carrying value is representative of its fair value.

The fair value of the notes payable is estimated to be $514.3$491.0 million at September 30, 2018.March 31, 2019. The Company determined the fair value of its notes payable at September 30, 2018March 31, 2019 by using observable market-based information for these debt instruments. The Company has classified the notes payable as Level 1.

11.10.Equity and Stock-Based Compensation

Equity

At the 2018 annual meeting of shareholders of the Company held on May 18, 2018, the shareholders approved the Third Amended and Restated Articles of Incorporation of the Company to increase the number of authorized shares of common stock of the Company from 300,000,000 to 400,000,000.

Stock-Based Compensation

In addition to cash compensation, the Company may compensate employees and directors with equity-based compensation in the form of stock options, performance-vested stock units, restricted stock units, stock bonus shares, and other equity awards. The Company records its equity compensation by pro-rating the estimated grant-date fair value of each grant over the period of time that the recipient is required to provide services to the Company (the "vesting period").  The calculation of fair value is based, either directly or indirectly, on the quoted market value of the Company’s common stock.  Indirect valuations are calculated using the Black-Scholes-Merton option pricing model or a Monte Carlo model. For the periods presented, all stock-based compensation was either classified as a component within general and administrative expense in the Company's condensed consolidated statements of operations or, for that portion which is directly attributable to individuals performing acquisition, exploration, and development activities, was capitalized to the full cost pool. As of September 30, 2018,March 31, 2019, there were 10,500,000 common shares authorized for grant under the 2015 Equity Incentive Plan, of which 4,251,4101,097,165 shares were available for future grant. The shares available for future grant exclude 1,555,2631,973,768 shares which have been reserved for future vesting of performance-vested stock units in the event that these awards meet the criteria to vest at their maximum multiplier.

Restricted stock units and stock bonus awards

The Company grants restricted stock units and stock bonus awards to directors, eligible employees, and officers under its equity incentive plan.  Restrictions and vesting periods for the awards are determined by the Compensation Committee of the Board of Directors and are set forth in the award agreements. Each restricted stock unit or stock bonus award represents one share of the Company’s common stock to be released from restrictions upon completion of the vesting period. The awards typically vest in equal increments over three to five years. Restricted stock units and stock bonus awards are valued at the closing price of the Company’s common stock on the grant date and are recognized over the vesting period of the award.

Performance-vested stock units

The Company grants twohas granted three types of performance-vested stock units ("PSUs") to certain executives under its long-term incentive plan. The number of shares of the Company’s common stock that may be issued to settle PSUs ranges from zero to two times the number of PSUs awarded. The shares issued for PSUs are determined based on the Company’s performance over a three-year measurement period and vest in their entirety at the end of the measurement period. TheFor the years prior to 2019, the PSUs will be settled in shares of the Company’s common stock followingstock. For PSUs granted in 2019, if the PSUs vested are in an amount equal to or less than the target amount, they will be settled in shares of the Company's common stock. If the PSUs vested are in an amount greater than the target amount, then at the discretion of of the Board of Directors, the value of the vested amount of PSUs in excess of the value of the PSU target amount may be paid wholly or partially in cash. All PSUs are settled at the end of the three-year performance cycle. Any PSUs that have not vested at the end of the applicable measurement period are forfeited.

Goal-Based PSUs - These PSUs are earned and vested after 2020 based on a discretionary assessment by the Compensation Committee. This assessment is anticipated to measure the performance of the Company and the executives over the defined vesting period. As vesting is based on the discretion of the Compensation Committee, we have not yet met the requirements of establishing an accounting grant date for them.  This will occur when the Compensation Committee determines and communicates the vesting percentage to the award recipients, which will then trigger the service inception date, the fair value of the awards, and the associated expense recognition period.  As of September 30, 2018, 281,872March 31, 2019, 274,898 Goal-Based PSUs had been awarded to certain executives.

Relative Total Shareholder Return ("Relative TSR") PSUs - The vesting criterion for the Relative TSR PSUs is based on a comparison of the Company’s TSRtotal shareholder return ("TSR") for the measurement period compared with the TSRs of a group of peer companies for the same measurement period. As the vesting criterion is linked to the Company's share price, it is considered a market condition for purposes of calculating the grant-date fair value of the awards.

Absolute Total Shareholder Return ("Absolute TSR") PSUs - The vesting criterion for the Absolute TSR PSUs is based on a comparison of the Company’s TSR for the measurement period compared to the absolute TSR goals outlined in the award. As the vesting criterion is linked to the Company's share price, it is considered a market condition for purposes of calculating the grant-date fair value of the awards.

13.12.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 earnings compared to annual projections, our effective tax rate may vary quarterly and may make quarterly comparisons not meaningful. The quarterly income tax provision

is generally comprised of tax expense on income or benefit on loss at the most recent estimated annual effective tax rate, adjusted for the effect of discrete items.

DuringThe effective combined U.S. federal and state income tax rate for the three months ended March 31, 2019 was 27%. For the three months ended March 31, 2018, the Company concluded it is more likely than not it will realize the benefits of its net deferred tax assets by the end of 2018 as a result of current year ordinary income. This conclusion was based upon the Company’s projection of cumulative positive net income for the three-year period ended December 31, 2018. The release of the valuation allowance is reflected in the Company’s estimated annual effective tax rate since the realization of the Company’s deferred tax assets is supported by current year ordinary income. The Company is projecting a net deferred tax liability with a full release of its beginning valuation allowance by the end of 2018.

was 8%. The effective tax rates for the three and nine months ended September 30,March 31, 2019 differed from the statutory rate primarily due to state income taxes, non-deductible expenses, and tax deficiencies recognized with the vesting of stock awards. The 2018 were 12% and 9%, respectively. For the three and nine months ended September 30, 2017, the effective tax rates were nil. The effective tax rates for the three and nine months ended September 30, 2018 and 2017 differed from the statutory rates due primarily to the release of valuation allowances previously recorded against deferred tax assets.

As of September 30, 2018,March 31, 2019, we had no liability for unrecognized tax benefits. The Company believes that there are no new items or changes in facts or judgments that should impact the Company’s tax position. Given the substantial NOL carryforwards at both the federal and state levels, it is anticipated that any changes resulting from a tax examination would simply adjust the carryforwards and would not result in significant interest expense or penalties.  Most of the Company's tax returns filed since August 31, 2011 are still subject to examination by tax authorities. As of the date of this report, we are current with our income tax filings in all applicable state jurisdictions, and we are not currently under any state income tax examinations.

No significant uncertain tax positions were identified as of any date on or before September 30, 2018.March 31, 2019.  The Company’s policy is to recognize interest and penalties related to uncertain tax benefits in income tax expense.  As of September 30, 2018,March 31, 2019, the Company has not recognized any interest or penalties related to uncertain tax benefits.

    Each period, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. As of September 30, 2018,March 31, 2019, the Company believes it will be able to generate sufficient future taxablepositive income within the carryforward periods and, accordingly, believes that it is more likely than not that its net deferred income tax assets will be fully realized. In addition to the future positive net income, the temporary deferred tax liabilities exceed the deferred tax assets resulting in the ability to utilize all deferred tax assets to offset future taxable income resulting from the reversal of the deferred tax liabilities.

14.13.    Revenue from Contracts with Customers

Sales of oil, natural gas, and NGLs are recognized at the point control of the product is transferred to the customer and collectability is reasonably assured. All of our contracts’ pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of the oil or natural gas, and prevailing supply and demand conditions. As a result, the price of the oil, natural gas, and NGLs fluctuates to remain competitive with other available oil, natural gas, and NGLs supplies.

Under our natural gas processing The Company evaluates contractual arrangements at inception to determine if individual agreements are a lease or contain an identifiable lease component as defined by ASC 842. When evaluating contracts we deliver natural gas to a midstream processing entity atdetermine appropriate classification and recognition under ASC 842, significant judgment may be necessary to determine, among other criteria, if an embedded leasing arrangement exists, the wellhead or the inletlength of the midstream processing entity’s system.term, classification as either an operating or financing lease, whether renewal or termination options are reasonably certain to be exercised, and future lease payments to be included in the initial measurement of the ROU asset. Certain assumptions and judgments made by the Company when evaluating contracts that meet the definition of a lease under ASC 842 include:

Discount Rate - Unless implicitly defined, the Company will determine the present value of future lease payments using an estimated incremental secured borrowing rate based on a yield curve analysis that factors in certain assumptions, including the term of the lease and credit rating of the Company at lease commencement.
Lease Term - The midstream processing entity gathersCompany evaluates each contract containing a lease arrangement at inception to determine the length of the lease term when recognizing a ROU asset and processescorresponding lease liability. When determining the natural gaslease term,

options available to extend or early terminate the arrangement are evaluated and remits proceedsincluded when it is reasonably certain these options will be exercised. There are no available options to us for the resulting sales of NGLs and residue gas. For these contracts, we have concludedextend that the midstream processing entityCompany is reasonably certain to exercise.

Currently, the Company has operating leases for asset classes that include office space, drilling rigs, and equipment rentals primarily used in development and field operations. The Company has financing leases for vehicles. We have provided a residual value guarantee for our customer. We recognize natural gas and NGL revenues basedvehicle leases. Certain leases also contain optional extension periods that allow for lease terms to be extended for up to an additional 5 years.

Costs associated with the Company’s operating leases are either expensed or capitalized depending on how the net amountunderlying asset is utilized. For example, costs associated with drilling rigs are capitalized as part of the proceeds receiveddevelopment of the Company’s oil and gas properties. Refer to the Company’s 2018 Form 10-K for additional information on its accounting policies for oil and gas development and producing activities. When calculating the Company’s ROU asset and liability, the Company considers all the necessary payments made or that are expected to be made upon commencement of the lease. Excluded from the midstream processing.initial measurement are certain variable lease payments.

We deliver oil to the purchaser at a contractually agreed-upon delivery point at which the purchaser takes custody, title, and risk of loss of the product. Under this arrangement, we pay a third party to transport the product and receive a specified index price from the purchaser, net of pricing differentials. In this scenario, we recognize revenue when control transfers to the purchaser at the delivery point based on the price received from the purchaser. The third party costs are recorded as transportation and gathering in our condensed consolidated statements of operations.

Transaction Price Allocated to Remaining Performance Obligations

A significant number of our product sales are short-term in nature with a contract term of one year or less. For those contracts, we have utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

For our product sales that have a contract term greater than one year, we have utilized the practical expedient in ASC 606-10-50-14(a) which states the Company is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Contract Balances

Under our product sales contracts, we invoice customers once our performance obligations have been satisfied, at which point payment is unconditional. Accordingly, our product sales contracts do not typically give rise to contract assets or liabilities under ASC 606. As of September 30, 2018, we had contract assets recorded within other current assets of $1.6 million representing cash advances to customers which are expected to be realized within a year.

Prior-Period Performance Obligations

We record revenue in the month production is delivered to the purchaser. However, settlement statements for certain sales may not be received for 30 to 90 days after the date production is delivered, and as a result, we are required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. We record the differences between our estimates and the actual amounts received for product sales when that payment is received from the purchaser. We have existing internal controls for our revenue estimation process and related accruals, and any identified differences between our revenue estimates and actual revenue received historically have not been significant. For the three and nine months ended September 30, 2018, revenue recognized in the reporting period related to performance obligations satisfied in prior reporting periods was not material.


15.Other Commitments and Contingencies

Oil Commitments

The Company entered into firm sales agreements for its oil production with four counterparties. Deliveries under three of the sales agreements have commenced. Deliveries under the fourth agreement are expected to commence in the first quarter of 2019. Pursuant to these agreements, we must deliver specific amounts of oil either from our own production or from oil that we acquire from third parties. If we are unable to fulfill all of our contractual obligations, we may be required to pay penalties or damages pursuant to these agreements. Our commitments, over the next five years, excluding the contingent commitment described below, are as follows:
Year ending December 31, Oil
 (MBbls)
Remainder of 2018 1,072
2019 5,167
2020 4,003

Total 9,568


During the thirdfirst quarter of 2018,2019, we were able to meet all of our delivery obligations, and we anticipate that our current gross operated production will continue to meet our future delivery obligations; although,obligations. However, this cannot be guaranteed.

Natural Gas Commitments

In collaboration with several other producers and DCP Midstream, LP ("DCP Midstream"), we have agreed to participate in the expansion of natural gas gathering and processing capacity in the D-J Basin.
The first agreement includes a newthe 200 MMcf per day processing plant ("Mewbourn 3") as well as the expansion of a related gathering system. Starting in August 2018, Mewbourn 3 was complete and in service. Our share of the commitment requires 46.4 MMcf per day to be delivered after the plant in-service date for a period of 7 years.
The second agreement includes an additional 300200 MMcf per day processing plant ("O'Connor 2"), including up to as well as an incremental 100 MMcf per day of bypass as well asand the expansion of a related gathering system. Construction of the plant is underway, and it is expected to be placed into service late in the second quarter of 2019. Our share of the commitment will require an additional 43.8 MMcf per day to be delivered after the plant in-service date for a period of 7 years.

These contractual obligations can be reduced by the collective volumes delivered to the plants by other producers in the D-J Basin that are in excess of such producers' total commitment. If we are unable to fulfill all of our contractual obligations and our obligations are not sufficiently reduced by the collective volumes delivered by other producers, we may be required to pay penalties or damages pursuant to these agreements. Our share of the commitment does not guarantee us a corresponding capacity for future deliveries to system. During the thirdfirst quarter of 2018,2019, we were able to meet all of our delivery obligations, and we anticipate that our current gross operated production will continue to meet our future delivery obligations; although,obligations. However, this cannot be guaranteed.

Litigation

From time to time, the Company is a party to various commercial and regulatory claims, pending or threatened legal action, and other proceedings that arise in the ordinary course of business. It is the opinion of management that none of the current proceedings are reasonably likely to have a material adverse impact on the Company's business, financial position, results of operations, or cash flows.

Office leases

The Company’s principal office space located in Denver is under lease through July 2022. Current rent under the lease is approximately $66,000 per month. The Company also has a field office lease in Greeley which requires monthly payments of $7,500 through October 2021.


Rent expense for offices leases was $0.3 million and $0.2 million for the three months ended September 30, 2018 and 2017, respectively. For the nine months ended September 30, 2018 and 2017, rent expense for office leases was $0.7 million and $0.9 million, respectively.

Vehicle Leases

The Company has entered into a leasing arrangement for its vehicles used in our operations. These leases terminate after four years and are classified as capital leases. The assets associated with these capital leases are recorded within "Other property and equipment, net."

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

Introduction

The following discussion and analysis was prepared to supplement information contained in the accompanying condensed consolidated financial statements and is intended to explain certain items regarding the Company's financial condition as of September 30, 2018March 31, 2019 and its results of operations for the three and nine months ended September 30, 2018March 31, 2019 and 2017.2018.  It should be read in conjunction with the “Selected Financial Data” and the accompanying audited consolidated financial statements and related notes thereto contained in the Annual Report on Form 10-K for the year ended December 31, 20172018 filed with the SEC on February 21, 2018.20, 2019. Unless the context otherwise requires, references to "SRC Energy," "we," "us," "our," or the "Company" in this report refer to the registrant, SRC Energy Inc., and its subsidiaries.

This section and other parts of this Quarterly Report on Form 10-Q contain forward-looking statements that involve risks and uncertainties.  See the “Cautionary Statement Concerning Forward-Looking Statements” elsewhere in this Quarterly Report on Form 10-Q.  Forward-looking statements are not guarantees of future performance, and our actual results may differ significantly from the results discussed in the forward-looking statements.  Factors that might cause such differences include, but are not limited to, those discussed and referenced in “Risk Factors.”  We assume no obligation to revise or update any forward-looking statements for any reason, except as required by law.

Proposition 112

As discussed in the "Risk Factors" section of this report, certain groups opposed to oil and natural gas hydraulic fracturing operations have proposed Proposition 112, which is included on Colorado’s November 6, 2018 ballot. Proposition 112 would impose a minimum setback distance of 2,500 feet between any new oil and gas development and any occupied structures or defined "vulnerable areas." If this proposition is enacted, it would apply prospectively to oil and gas development permitted on or after the effective date of the law, which is expected to be December 2018. Although there is significant uncertainty about how this law would be interpreted and implemented, if approved by the voters, it could have significant adverse effects on the Company’s long-term operations, reserves, and financial condition.  See “Risk Factors - Proposition 112, if approved, would have a material adverse effect on our future drilling inventory and other aspects of our business.” If Proposition 112 is enacted, we will consider all available courses of action, including potential legal challenges, legislative reformation, and regulatory modifications, but the outcome of any such efforts and the effect that they might have on the Company is unknown. We do not believe that Proposition 112 would impact existing wells, current drilling or completion activities, or future wells that have been approved by the state. We currently have state-approved and permitted drilling locations that we believe would be grandfathered under Proposition 112 and would provide approximately two years of drilling inventory.

Overview

SRC Energy is an independent oil and gas company engaged in the acquisition, development, and production of oil, natural gas, and NGLs in the D-J Basin, which we believe to be one of the premier, liquids-rich oil and natural gas resource plays in the United States. It contains hydrocarbon-bearing deposits in several formations, including the Niobrara, Codell, Greenhorn, Shannon, Sussex, J-Sand, and D-Sand. The area has produced oil and natural gas for over fifty years and benefits from established infrastructure, long reserve life, and multiple service providers.

Our oil and natural gas activities are focused in the Wattenberg Field, predominantly in Weld County, Colorado, an area that covers the western flank of the D-J Basin. Currently,All of our activities and planned drilling locations are located in Weld County, Colorado, and we are focused on the horizontal development of the Codell formation as well as the three benches of the Niobrara formation, which are all characterized by relatively high liquids content.

In order to maintain operational focus while preserving developmental flexibility, we strive to attain operational control of a majority of the wells in which we have a working interest. We currently operate approximately 85%91% of our proved developed reserves and anticipate operating a majority of our future net drilling locations. Additionally, our current development plan anticipates that all of our future activities will be concentrated in the Wattenberg Field.


Market Conditions

Market prices for our products significantly impact our revenues, net income, cash flow, future growth, and cash flow.carrying value of our oil and gas properties.  The market prices for oil, natural gas, and NGLs are inherently volatile.  To provide historical perspective, the following table presents the average annual NYMEX prices for oil and natural gas for each of the last five fiscalfour years.

Market conditions in the Wattenberg Field can require us to sell oil at prices less than the prices posted by the NYMEX. The differential between the prices actually received by us at the wellhead and the published indices reflects deductions imposed upon us by the purchasers for location and quality adjustments. With regard toTo the sale of oil, substantially all of the Company's first quarter 2017 oil production was sold to the counterparties of its firm sales commitments. Beginning in the second quarter of 2017 and continuing through the current period,extent the Company's oil production exceeded its firm sales commitments andduring the three months ended March 31, 2019, the surplus oil production was sold at a reduced differential as compared to our committed volumes.

Our revenues, results of operations, profitability, future growth, and carrying value of our oil and gas properties depend primarily on the prices that we receive for our oil, natural gas, and NGL production. There has been significant volatility in the price of oil and natural gas since mid-2014.  During the nine months ended September 30, 2018, the NYMEX-WTI oil price ranged from a high of $77.41 per Bbl on June 27, 2018 to a low of $59.20 per Bbl on February 9, 2018, and the NYMEX-Henry Hub natural gas price ranged from a low of $2.55 per MMBtu on February 12, 2018 to a high of $3.63 per MMBtu on January 29, 2018. As reflected in published data, the price for WTI oil settled at $60.46 per Bbl on December 29, 2017.  Comparably, the price of oil settled at $73.16 per Bbl on Friday, September 28, 2018, an increase of 21% from December 29, 2017. NYMEX-Henry Hub natural gas traded at $2.95 per Mcf on December 29, 2017, but increased approximately 2% as of September 28, 2018 to $3.01. While we use NYMEX-Henry Hub to calculate our natural gas differentials, our natural gas sales tend to trend more closely with Colorado Interstate Gas – Rocky Mountains as published in Inside FERC’s Gas Market Report, published by Platts ("CIG"). Average CIG prices for the thirdfirst quarter of 2019 decreased to $2.95 from $3.06 in the fourth quarter of 2018, increased to $2.18 from $1.83resulting in the second quarter of 2018, and the basis difference for CIG to NYMEX-Henry Hub decreaseddecreasing from $0.97$0.58 to $0.72.$0.20.

A decline in oil and natural gas prices will adversely affect our financial condition and results of operations.  Furthermore, low oil and natural gas prices can result in an impairment of the value of our properties and impact the calculation of the “ceiling test” required under the accounting principles for companies following the “full cost” method of accounting.  At September 30, 2018,March 31, 2019, the calculated value of the ceiling limitation exceeded the carrying value of our oil and gas properties subject to the test, and no impairment was necessary.

In addition to the producing wells summarized in the preceding table, as of September 30, 2018,March 31, 2019, we were the operator of 7766 gross (66(56 net) horizontal wells in progress, which excludes 30 gross (23 net) wells for which we have only set surface casings.progress. As of September 30, 2018,March 31, 2019, we are participating in 2917 gross (9(2 net) non-operated horizontal wells in progress.

As we develop our acreage through horizontal drilling, we have an active program for the remediation and reclamation

of the vast majority of the operated vertical wellbores. During the ninethree months ended September 30, 2018,March 31, 2019, we plugged 146reclaimed 34 wells and returned the associated acreage to the property owners.

Drilling and Completion Operations

Our drilling and completion schedule drives our production forecast and our expected future cash flows. We believe that at current drilling and completion cost levels and with currently prevailing commodity prices, we can achieve attractive well-level rates of return. Should commodity prices weaken or our costs escalate significantly, our operational flexibility will allow us to adjust our drilling and completion schedule, if prudent. If the well-level internal rate of return is at or below our weighted-average cost of capital, we may choose to delay completions and/or forego drilling altogether. Conversely, if commodity prices move higher and operating conditions are favorable, we may choose to accelerate drilling and completion activities, assuming adequate gas processing capacity is available at the time.

During the three months ended March 31, 2019, we drilled 28 operated horizontal wells and turned 33 operated horizontal wells to sales. As of March 31, 2019, the Company had 18 gross (16 net) wells that were drilled and completed, but not producing. These wells are expected to be turned to sales during the second quarter. As of March 31, 2019, we are the operator of 66 gross (56 net) horizontal wells in progress. All of this activity was funded through cash flows from operations. For 2019 as a whole, we expect to drill 99 gross (90 net) operated horizontal wells and complete approximately 68 gross (62 net) operated horizontal wells with mid-length and long laterals targeting the Codell and Niobrara formations.

For the three months ended March 31, 2019, we participated in the completion of7gross (0.1net) non-operated horizontal wells. As ofMarch 31, 2019, we are participating in17gross (2net) non-operated horizontal wells in progress.

Production

For the three months ended September 30, 2018,March 31, 2019, our average daily production increased to 49,16565,771 BOED as compared to 40,37845,397 BOED for the three months ended September 30, 2017. During the first nine months of 2018, our average net daily production was 47,416 BOED. By comparison, during the nine months ended September 30, 2017, our average production rate was 30,331 BOED.March 31, 2018. As of September 30, 2018,March 31, 2019, over 99%98% of our daily production was from horizontal wells.

As of March 31, 2019, we had 137 wells shut-in, due primarily to the lack of capacity to process gas. Throughout 2018, we continued to drill and complete wells in an attempt to maintain oil volumes and to limit the potential impact of Proposition 112, a ballot measure voted on in November 2018 that, if it had passed, would have severely limited our future drilling locations. In light of our 2018 activity levels and the voting down of Proposition 112, we planned our 2019 budgeted activity to adjust the cadence of both drilling and completion operations and reduced our year-over-year capital expenditures budget by approximately 35% in order to optimize capital efficiency. The aggregate volumes that were being produced at the time that these wells were shut-in was approximately 20,000 BOED with an approximate 40% oil cut.

Strategy

Our primary objective is to enhance shareholder value by increasing our net asset value, net reserves, and cash flow through development, exploitation, and acquisitions of oil and gas properties. We intend to follow a balanced risk strategy by allocating capital expenditures to lower risk development and exploitation activities. Key elements of our business strategy include the following:

Concentrate on our existing core area in the D-J Basin, where we have significant operating experience.  All of our current wells and our proved undeveloped acreage are located either in or adjacent to the Wattenberg Field, and we seek to acquire developed and undeveloped oil and gas properties in the same contiguous area. Focusing our operations in this area leverages our management, technical, and operational experience in the basin.

Maximize shareholder value and maintain financial flexibility by limiting the need for external capital.  We seek to align our capital expenditures with our cash flows by adjusting our operating activities depending on commodity prices and infrastructure capacity. We strive to be a cost-efficient operator and to maintain a relatively low utilization of debt, which allows sufficient financial capacity to pursue strategic acquisitions.

Develop and exploit existing oil and gas properties.  OurA principal growth strategy has been to develop and exploit our properties to add reserves.  In the Wattenberg Field, we target three benches of the Niobrara formation as well as the Codell formation for horizontal drilling and production. We believe horizontal drilling is the safest and most efficient and safesteconomical way to recover the potential hydrocarbons and consider the Wattenberg Field to be relatively low-risk because information gained from the large number of existing wells can be applied to potential future wells.  There is

enough similarity between wells in the Wattenberg Field that the exploitation process is generally repeatable.

Use the latest technology to maximize returns and improve hydrocarbon recovery.  Our development objective for individual well optimization is to primarily drill and complete wells with lateral lengths of mostly 7,000' to 10,000'. Utilizing petrophysical and seismic data, a 3-D model is developed for each leasehold section to assist in determining optimal wellbore placement, well spacing, and stimulation design. This process is augmented with formation-specific drilling and completion execution designs, and coupled with localized production results, to implement a continuous improvement philosophy in optimizing the value per acre of our leasehold throughout our development program.

Control and reduce emissions from our production facilities. We place high importance on achieving compliance with all applicable air quality rules and regulations and further reducing emissions continues to be a top priority. To minimize emissions, we employ best management practices such as using available direct pipeline take-away access and pneumatic actuated instrument devices and by working with suppliers to deploy diesel engines that meet the U.S. Environmental Protection Agency Tier 4 standard. We control emissions and minimize flaring of gas during the drilling and completion process. We use additional vapor recovery equipment during production for further emissions reduction. We continue to evolve the design of our production facilities to produce oil and natural gas with fewer air emissions, including those emissions for which there are public health standards (e.g. ozone and particulate matter).

Operate in a safe manner and work in partnership with our surrounding stakeholders.  While our scale of operations has increased significantly, we continue to focus on maintaining a safe workplace for our employees and contractors. Further, as technology for resource development has advanced, we seek to utilize best industry practices to meet or exceed regulatory requirements while reducing our impacts on neighboring communities. Such practices include building our infrastructure out ahead of operations to minimize traffic, working with our service providers to minimize dust and lighting issues, and constructing sound walls to minimize noise.  We value our positive relationship with local governing entities and the communities in which we operate and seek to continually achieve a status of operator of choice.

Retain control over the operation of a substantial portion of our production. As operator of a majority of our wells and undeveloped acreage, we control the timing and selection of new wells to be drilled.  This allows us to modify our capital spending as our financial resources and underlying lease terms allow and market conditions, including midstream availability, permit.

Maintain financial flexibility while focusing on operational cost control.  We strive to be a cost-efficient operator and to maintain a relatively low utilization of debt, which enhances our financial flexibility. Our high degree of operational control, as well as our focus on operating efficiencies andthat provide short return on investment cycle times, is central to our operating strategy.

Acquire and develop assets near established infrastructure. We have madetarget acquisitions of contiguous acreage and alignedto focus our development plans on areas where technically-capable, financially-stable midstream companies have existing assets and plans for additional investment. We work collaboratively with these companies to proactively identify expansion opportunities that complement our development plans while reducing truck traffic.

Control and reduce emissions from our production facilities. We place high importance on achieving compliance with all applicable air quality rules and regulations and reducing emissions continues to be a top environmental priority. To minimize these emissions, we employ best management practices such as using available direct pipeline take-away access and pneumatic actuated instrument devices and working with suppliers to deploy diesel engines that meet the U.S. Environmental Protection Agency Tier 4 standand. We also control emissions and minimize flaring of gas by recovering natural gas and actively pursuing sufficient take-away capacity for associated produced gas andplans. This enables the use of vapor recovery equipment. We continuegathering pipelines, which reduces the need to evolve the design of our production facilities to produce oiluse trucks and natural gas with fewer air emissions, including those emissions for which there are public health standards (e.g. ozonethereby reduces traffic and particulate matter).noise.

Significant Developments

Acquisitions and TradeLegislative Matters

In September 2018,The Colorado General Assembly passed SB19-181, titled "Protect Public Welfare Oil And Gas Operations" in April 2019. Among other things, SB19-181 provides that local governments have land use authority to regulate the Company completed the purchasesiting of verticaloil and horizontal wellsgas locations, states that it is in the Greeley-Crescentpublic interest to regulate the development areaof oil and gas resources in a manner that protects public health, safety, and welfare, including protection of the environment and wildlife resources, and modifies the requirements related to statutory pooling. There will be significant rule making associated with this legislation that will affect the implementation and effect of the law. SB19-181 could have a variety of effects on our operations, but we believe that some of these impacts may be mitigated by the fact that the statute places a significant emphasis on local control of oil and gas regulatory matters, and all of our planned future development activities are in Weld County, Colorado for $64.1 milliona jurisdiction in cash and the assumption of certain liabilities forwhich there is a total purchase price of $96.8 million. The effective date of this purchase was September 1, 2018.

In September 2018, we completed a trade with another party of approximately 2,500 net acres. This transaction further enhances the contiguous naturestrong support of the Company's acreage position.

In August 2018, the Company completed the purchase of leasehold acreageoil and associated non-operated production for $37.6 million in cash and the assumption of certain liabilities for a total purchase price of $38.0 million. The acreage increased our working interest in existing operations and planned wells.gas industry.

Revolving Credit Facility

In October 2018,April 2019, the lenders under the Revolver completed their semi-annual redetermination of our borrowing base. The borrowing base was increased from $550$650 million to $650$700 million, and we increased our aggregate elected commitment from $450$500 million to $500$550 million.

Drilling and Completion Operations

Our drilling and completion schedule drives our production forecast and our expected future cash flows. We believe that at current drilling and completion cost levels and with currently prevailing commodity prices, we can achieve attractive well-level rates of return. Should commodity prices weaken or our costs escalate significantly, our operational flexibility will allow us to adjust our drilling and completion schedule, if prudent. If the well-level internal rate of return is at or below our weighted-average cost of capital, we may choose to delay completions and/or forego drilling altogether. Conversely, if commodity prices move

higher, we may choose to accelerate drilling and completion activities.

During the nine months ended September 30, 2018, we drilled 89 operated horizontal wells and turned 54 operated horizontal wells to sales. As of September 30, 2018, the Company had 9 gross (8 net) wells that were drilled and completed, but not producing. These wells are expected to be turned to sales during the fourth quarter. As of September 30, 2018, we are the operator of 77 gross (66 net) horizontal wells in progress, which excludes30gross (23net) horizontal wells for which we have only set surface casings. The majority of this activity was funded through cash flows from operations. For 2018 as a whole, we expect to drill 118 gross (101 net) operated horizontal wells and complete approximately 127 gross (112 net) operated horizontal wells with mid-length and long laterals targeting the Codell and Niobrara formations.

For the nine months ended September 30, 2018, we participated in the completion of32gross (6net) non-operated horizontal wells. As ofSeptember 30, 2018, we are participating in29gross (9net) non-operated horizontal wells in progress.

Trends and Outlook

NYMEX-WTI oil traded at $60.4645.15 per Bbl on December 29, 2017,28, 2018, but has since increased approximately 21%33% as of September 28, 2018March 29, 2019 to $73.16.60.19. NYMEX-Henry Hub natural gas traded at $2.953.25 per Mcf on December 29, 2017,28, 2018, but increaseddeclined approximately 2%16% as of September 28, 2018March 29, 2019 to $3.01.2.73. Although NYMEX-WTI oil prices have increased over the first quarter in 2018,2019, they continue to be volatile and are out of our control. If oil prices decrease, this could (i) reduce our cash flow which could, in turn, reduce the funds available for exploringthe exploration and replacingreplacement of oil and natural gas reserves, (ii) reduce our Revolver borrowing base capacity and increase the difficulty of obtaining equity and debt financing and worsen the terms on which such financing may be obtained, (iii) reduce the number of oil and gas prospects which have reasonable economic returns, (iv) cause us to allow leases to expire based upon the value of potential oil and natural gas reserves in relation to the costs of exploration, (v) result in marginally productive oil and natural gas wells being abandonedshut-in as non-commercial, and (vi) cause ceiling test impairments.

We continually focus on managing drilling and completion costs through a combination of well design optimization, reductions in the average days to drill, and employment of current technological advancements. This focus on cost management helps support well-level economics under varying oil and natural gas pricing environments.

MidstreamMultiple midstream companies that operate the natural gas processing facilities and gathering pipelines in the Wattenberg Field continue to make significant capital investments to increase the capacity of their systems. FromUntil such time to time,that these facilities are operational, our production has been, and maymost likely will continue to be, adversely impacted by thea lack of available processing capacity, resulting in high natural gas gathering line pressures. Second and third quarter 2018 results were impacted by this lack of spare gas processing capacity, which resulted in persistently high line pressures and the inability to maintain consistent production flows. Further exacerbating the midstream constraints were above average temperatures in Colorado in June and continuing into July as well as unplanned shutdowns of natural gas processing facilities. As a result, many of the Company's wells could not be produced consistently, and the Company was unable to turn recently completed wells to sales as desired. capacity.

To address the growing volumes of natural gas production in the D-J Basin, DCP Midstream ishas been developing multiple projects including new processing plants, an expansion of its low and high pressure gathering systems, additional compression, and plant bypass infrastructure. Most notably, in collaboration with DCP Midstream, we and several other producers have agreed to support the expansion of natural gas gathering and processing capacity through agreements that impose baseline and incremental volume commitments, which we are currently exceeding.  The initialCurrent plans included a new 200 MMcf per day processing plant ("Mewbourn 3"), and the expansion of a related gathering system, which became operational in August 2018. Through the same framework, all of the parties agreed to a development planare to add another 300200 MMcf per day plant ("O'Connor 2"), including up to as well as an incremental 100 MMcf per day of bypass, thatbypass. The O'Connor plant is expected to be in service in the second quarter of 2019.followed by the bypass later in the year. In addition, DCP Midstream has announced that it has secured the land and permits for the development of a third plantfacility ("Bighorn"), which could have processing capacity of up to 1 Bcf per day, including bypass, and is expected to be placed into service in phases with anthe initial in-service date after 2019.in mid-2020.

As a result of the current lack of gas processing capacity, a system-wide volume allocation limiting each producer’s throughput was implemented in November 2017 and has not since been lifted.

We have extended the use of oil and water gathering lines to certain production locations. These gathering systems are owned and operated by independent third parties, and we commit specific leases or areas to these systems. We believe these gathering lines have several benefits, including a) reduced need to use trucks, thereby reducing truck traffic and noise in and around our production locations, b) potentially lower gathering costs as pipeline gathering tends to be more efficient, c) reduced on-site storage capacity, resulting in lower production location facility costs, and d) generally improved community relations. As these gathering lines are currently beingcontinue to be expanded, we have experienced and expect tomay continue to experience some delays in placing our pads on production.

Oil transportation andpipeline takeaway capacity utilization has increased withas oil production in the basin has grown. However, the capacity will decrease in the second quarter of 2019 when a portion of a third-party crude oil pipeline system is converted to NGL service. To address the projected demand for additional capacity, several open seasons have been announced for the expansion of certain interstate pipelines servicing the Wattenberg Field. We continuously strive to reduce the negative differential that we have historically realized on our oil production depending

on transportation commitments, local refinery demand, and our production volumes. Further details regarding posted prices and average realized prices are discussed in "-Market Conditions."

For 2018,2019, we expect to drill 11899 gross operated horizontal wells (89(28 of which were drilled through September 30, 2018)March 31, 2019) with mostly mid-length and long laterals targeting the Codell and Niobrara zones. We anticipate thisthat total capital expenditures, including operated drilling and completion programcosts, limited leasehold acquisition costs and selected non-operated drilling and completion costs, will cost approximately $580be between $425 million ($408.3 and $450 million of which was incurred through September 30, 2018) and that it shouldwill lead to a significantan increase in production and associated proved developed producing reserves. We currentlyOur current estimate is that full-year 20182019 production will average approximately 50,000between 63,000 BOED and 66,000 BOED with theoil mix being approximatelymaking up 42% to 45% of production.

Other than the foregoing, and the aforementioned Proposition 112, we do not know of any trends, events, or uncertainties that have had, during the periods covered by this report, or are reasonably expected to have, a material impact on our sales, revenues, expenses, liquidity, or capital resources.

For the three months ended September 30, 2018March 31, 2019 compared to the three months ended September 30, 2017March 31, 2018

For the three months ended September 30, 2018,March 31, 2019, we reported net income of $62.6$49.8 million compared to net income of $43.8$65.8 million during the three months ended September 30, 2017.March 31, 2018. Net income per basic and diluted share was $0.26$0.20 for the three months ended September 30, 2018March 31, 2019 compared to net income per basic and diluted share of $0.22$0.27 for the three months ended September 30, 2017.March 31, 2018.

Oil, Natural Gas, and NGL Production and Revenues - For the three months ended September 30, 2018,March 31, 2019, we recorded total oil, natural gas, and NGL revenues of $161.0$189.5 million compared to $103.6$147.2 million for the three months ended September 30, 2017,March 31, 2018, an increase of $57.4$42.2 million or 55%29%.

Lease operating and workover costs tend to increase or decrease primarily in relation to the number and type of wells and, to a lesser extent, on fluctuations in oil field service costs and changes in the production mix of oil and natural gas. During the three months ended September 30, 2018,March 31, 2019, we experienced increased production expense compared to the three months ended September 30, 2017March 31, 2018 due to a 45%an 88% increase in net operated wells. In addition, elevated line pressures temporarily drove operating costs on a per unit basis higher in the third quarter of 2018 as the Company incurred incremental costs without the typical benefit of flush production from its new wells.

Transportation and gathering - Transportation and gathering was $2.0$4.1 million, or $0.44$0.68 per BOE, for the three months ended September 30, 2018March 31, 2019, compared to $0.8$1.9 million, or $0.23$0.45 per BOE, for the three months ended September 30, 2017.March 31, 2018. Coinciding with the increasing production in 2018, the Company has increased the volume of its production that is sold and delivered at the downstream interconnect. This has the effect of increasing both the net price received for the production and transportation and gathering costs. While costs attributable to volumes sold at the interconnect of the pipeline are reported as an expense, the Company analyzes these charges on a net basis within revenue for comparability with wellhead sales.

Production taxes - Production taxes are comprised primarily of two elements: severance tax and ad valorem tax. During the three months ended March 31, 2019, the Company reduced its estimate for 2018 severance taxes. When preparing the 2018 severance tax return, we determined that the credit for ad valorem taxes would be greater than originally estimated, resulting in a reduction of 2018 severance taxes. Based on this analysis, the Company's prior year accrual was reduced, resulting in an approximate $7.9 million reduction to our production taxes. Production taxes were $12.8$7.1 million, or $2.83$1.20 per BOE, for the three months ended September 30, 2018,March 31, 2019, compared to $10.1$13.4 million, or $2.71$3.29 per BOE, during the three months ended September 30, 2017. Taxes tend to increase or decrease primarily based on the value of production sold.March 31, 2018. As a percentage of revenues, production taxes were 8.0%3.7% and 9.7%9.1% for the three months ended September 30,March 31, 2019 and 2018, and 2017, respectively.respectively, with the 2019 period reflecting the effect of the change in estimate.

For the three months ended September 30, 2018,March 31, 2019, DD&A was $9.99$10.29 per BOE compared to $9.08 per BOE for the three months ended September 30, 2017March 31, 2018. The increase in the DD&A rate was the result of recent drilling and completion activities which increased the amortization base. Capitalized costs of proved oil and gas properties are depleted quarterly using the units-of-production method based on estimated reserves, whereby the ratio of production volumes for the quarter to the beginning of the quarter estimated total reserves determines the depletion rate.

G&A includes overhead costs associated with employee compensation and benefits, insurance, facilities, professional fees, and regulatory costs, among others. Total G&A costs of $10.7$9.5 million for the thirdfirst quarter of 20182019 were 26% higher1% lower than G&A for the same period of 2017. This increase is primarily due to a 25% increase in employee headcount from 117 at September 30, 2017 to 146 at September 30, 2018. Additionally, G&A for the three months ended September 30, 2018 was elevated by expenses incurred in support of Colorado oil and gas legislative activities.

Our G&A expense for the three months ended September 30, 2018March 31, 2019 includes stock-based compensation of $3.4$3.7 million compared to $3.0$2.8 million for the three months ended September 30, 2017.March 31, 2018.

Pursuant to the requirements under the full cost accounting method for oil and gas properties, we identify all general and administrative costs that relate directly to the acquisition of undeveloped mineral leases and the exploration and development of properties. Those costs are reclassified from G&A expenses and capitalized into the full cost pool. The increase in capitalized costs from the three months ended September 30, 2017March 31, 2018 to the three months ended September 30, 2018March 31, 2019 reflects our increased headcount of individuals performing activities to maintain and acquire leases and develop our properties.

Commodity derivative gains (losses) - As more fully described in Item 1. Financial Statements – Note 8,7, Commodity Derivative Instruments, we use commodity contracts to help mitigate the risks inherent in the price volatility of oil and natural gas. For the three months ended September 30, 2018,March 31, 2019, we realized a settlement lossgain of $8.3$4.9 million. For the prior comparable period, we realized a settlement gainloss of $0.1 million, net of previously incurred premiums attributable to the settled commodity contracts.2.1 million.

In addition, for the three months ended September 30, 2018,March 31, 2019, we recorded an unrealized loss of $0.3$27.8 million to recognize the mark-to-market change in fair value of our commodity contracts. InBy comparison, in the three months ended September 30, 2017,March 31, 2018, we reported an unrealized loss of $2.5$3.7 million. Unrealized losses are non-cash items.

Income taxes - As more fully described in Item 1. Financial Statements – Note 13,12, Income Taxes, we reported income tax expense of $8.9$18.0 million for the three months ended September 30, 2018March 31, 2019 as compared to no income tax expense$5.8 million for the comparable prior year period. The effective tax ratesrate for the three and nine months ended September 30,March 31, 2018 and 2017 differed from the statutory rates due primarily to the release of valuation allowances previously recorded against deferred tax assets.

For the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017

For the nine months ended September 30, 2018, we reported net income of $178.0 million compared to net income of $91.7 million during the nine months ended September 30, 2017. Net income per basic and diluted share was $0.74 and $0.73, respectively, for the nine months ended September 30, 2018 compared to net income per basic and diluted share of $0.46 for the nine months ended September 30, 2017.


Oil, Natural Gas, and NGL Production and Revenues - For the nine months ended September 30, 2018, we recorded total oil, natural gas, and NGL revenues of $455.3 million compared to $222.4 million for the nine months ended September 30, 2017, an increase of $232.9 million or 105%.

Lease operating and workover costs tend to increase or decrease primarily in relation to the number and type of wells and, to a lesser extent, on fluctuations in oil field service costs and changes in the production mix of oil and natural gas.During thenine months ended September 30, 2018, we experiencedincreasedproduction expense compared to thenine months ended September 30, 2017primarilydue to a 45% increase in net operated wells. In addition, elevated line pressures temporarily drove operating costs on a unit basis higher in the second and third quarter of 2018 as the Company incurred incremental costs without the typical benefit of flush production from its new wells.

Transportation and gathering - Transportation and gathering was $5.7 million, or $0.44 per BOE, for the nine months ended September 30, 2018, compared to $1.1 million, or $0.14 per BOE, for the nine months ended September 30, 2017. In the first half of 2017, a majority of the Company's production was delivered to the purchaser at the wellhead whereas, in 2018, the

Company has increased the proportion of its production that is sold and delivered at the downstream interconnect. This has the effect of increasing both the net price received for the production and transportation and gathering costs. While costs attributable to volumes sold at the interconnect of the pipeline are reported as an expense, the Company analyzes these charges on a net basis within revenue for comparability with wellhead sales.

Production taxes - Production taxes are comprised primarily of two elements: severance tax and ad valorem tax. Production taxes were $41.3 million, or $3.19 per BOE, for the nine months ended September 30, 2018, compared to $21.0 million, or $2.54 per BOE, for the nine months ended September 30, 2017. Taxes tend to increase or decrease primarily based on the value of production sold. As a percentage of revenues, production taxes were 9.1% and 9.4% for the nine months ended September 30, 2018 and 2017, respectively.

DD&A - The following table summarizes the components of DD&A:

For the nine months ended September 30, 2018, DD&A was $9.59 per BOE compared to $8.86 per BOE for the nine months ended September 30, 2017. The increase in the DD&A rate was the result of recent drilling and completion activities which increased the amortization base. Capitalized costs of proved oil and gas properties are depleted quarterly using the units-of-production method based on estimated reserves, whereby the ratio of production volumes for the quarter to the beginning of the quarter estimated total reserves determines the depletion rate.

G&A - The following table summarizes G&A expenses incurred and capitalized during the periods presented:

G&A includes all overhead costs associated with employee compensation and benefits, insurance, facilities, professional fees and regulatory costs, among others. Total G&A costs of $29.7 million for the nine months ended September 30, 2018 were 22% higher than G&A for the same period of 2017. This increase is primarily due to a 25% increase in employee headcount from 117 at September 30, 2017 to 146 at September 30, 2018. Additionally, G&A for the nine months ended September 30, 2018 was elevated by expenses incurred in support of Colorado oil and gas legislative activities during the third quarter of 2018.

Our G&A expense for the nine months ended September 30, 2018 includes stock-based compensation of $9.3 million compared to $8.4 million for the nine months ended September 30, 2017.

Pursuant to the requirements under the full cost accounting method for oil and gas properties, we identify all general and administrative costs that relate directly to the acquisition of undeveloped mineral leases and the exploration and development of

properties. Those costs are reclassified from G&A expenses and capitalized into the full cost pool. The increase in capitalized costs from the nine months ended September 30, 2017 to the nine months ended September 30, 2018 reflects our increased headcount of individuals performing activities to maintain and acquire leases and develop our properties.

Commodity derivatives - As more fully described in Item 1. Financial Statements – Note 8, Commodity Derivative Instruments, we use commodity contracts to help mitigate the risks inherent in the price volatility of oil and natural gas. For the nine months ended September 30, 2018, we realized a settlement loss of $16.2 million. For the prior comparable period, we realized a settlement loss of $26.0 thousand, net of previously incurred premiums attributable to the settled commodity contracts.

In addition, for the nine months ended September 30, 2018, we recorded an unrealized loss of $12.4 million to recognize the mark-to-market change in fair value of our commodity contracts. In comparison, in the nine months ended September 30, 2017, we reported an unrealized gain of $2.4 million. Unrealized gains and losses are non-cash items.

Income taxes - We reported income tax expense of $18.1 million for the nine months ended September 30, 2018 as compared to no income tax expense for the comparable prior year period. During the nine months ended September 30, 2018 and 2017, the effective tax rate differed from the statutory rate due primarily to the release of valuation allowances previously recorded against deferred tax assets.

Liquidity and Capital Resources

Historically, our primary sources of capital have been net cash provided by cash flow from operations, the sale of equity and debt securities, borrowings under bankrevolving credit facilities, and proceeds from the sale of properties.  Our primary use of capital has been for the exploration, development, and acquisition of oil and gas properties.  Our future success in growing proved reserves and production will be highly dependent on the capital resources available to us.

We believe that our current capital resources, including cash flows from operating activities, cash on hand, and amounts available under our revolving credit facility will be sufficient to fund our planned capital expenditures and operating expenses for the next twelve months. During the ninethree months ended September 30, 2018,March 31, 2019, our drilling and completions expenditures were primarily coveredcash provided by operating activities exceeded our cash flows from operatingused in investing activities. To the extent actual operating results differ from our anticipated results, available borrowings under our credit facility are reduced, or we experience other unfavorable events, our liquidity could be adversely impacted.  Our

liquidity would also be affected if we increase our capital expenditures or complete one or more additional acquisitions. Terms of future financings may be unfavorable, and we cannot assure investors that funding will be available on acceptable terms.

As operator of the majority of our wells and undeveloped acreage, we control the timing and selection of new wells to be drilled. This allows us to modify our capital spending as our financial resources allow and market conditions, including midstream availability, support. Additionally, our relatively low utilization of debt enhances our financial flexibility as it provides a potential source of future liquidity while currently not overly burdening us with restrictive financial covenants and mandatory repayment schedules.

Sources and Uses

Our sources and uses of capital are heavily influenced by the prices that we receive for our production. Oil and gas markets will likely continue to be volatile in the future. To deal with the volatility in commodity prices, we maintain a flexible capital investment program and seek to maintain a high operating interest in our leaseholds with limited long-term capital commitments. This enables us to accelerate or decelerate our activities quickly in response to changing industry environments.


At September 30, 2018,March 31, 2019, we had cash and cash equivalents and restricted cash of $19.2$56.8 million, $550.0 million outstanding on our Senior 2025 Notes, and a $115.0$195.0 million balance outstanding under our revolving credit facility. Our sources and (uses) of funds for the ninethree months ended September 30,March 31, 2019 and 2018 and 2017 are summarized below (in thousands):

Credit Facility

The Revolver has a maturity date of April 2, 2023.  The Revolver has a maximum loan commitment of $1.5 billion; however, the maximum amount available to be borrowed at any one time is subject to a borrowing base limitation, which stipulates that we may borrow up to the least of the aggregate maximum credit amount, the aggregate elected commitment, or the borrowing base.  The borrowing base can increase or decrease based upon the value of the collateral which secures any amounts borrowed under the Revolver.  The value of the collateral will generally be derived with reference to the estimated discounted future net cash flows from our proved oil and natural gas reserves. The collateral includes substantially all of our producing wells and developed oil and gas leases.

In October 2018,April 2019, the borrowing base was increased from $550650 million to $650 million; however,700 million, and our elected commitment amount was increased to $550 million from $500 million.million. As ofOctober March 31, 2018,2019, there was a $145.0$195.0 million principal balance outstanding and no letters of credit outstanding, leaving $355.0305.0 million available to us for future borrowings. The next semi-annual redetermination is scheduled for AprilOctober 2019. Interest on the Revolver accrues at a variable rate. The interest rate pricing grid provides for an escalation in applicable margin based on increased utilization of the Revolver.

The Revolver requires the Company to maintain compliance with certain financial and liquidity ratio covenants. In particular, the Company must not (a) permit its ratio of total funded debt to EBITDAX, as defined in the agreement, to be greater than or equal to 4.0 to 1.0 as of the last day of any fiscal quarter or (b) permit its ratio of current assets to current liabilities, each as defined in the agreement, to be less than 1.0 to 1.0 as of the last day of any fiscal quarter.

2025 Senior Notes

In November 2017, the Company issued $550 million aggregate principal amount of 6.25% Senior Notes due 2025 (the 2025"2025 Senior Notes)Notes") in a private placement to qualified institutional buyers. The maturity for the payment of principal is

December 1, 2025. Interest on the 2025 Senior Notes accrues at 6.25% and began accruing on November 29, 2017.. Interest is payable on June 1 and December 1 of each year, beginning on June 1, 2018.year.

The 2025 Senior Notes were issued pursuant to an indenture dated as of November 29, 2017 (the "Indenture") and are guaranteed on a senior unsecured basis by the Company’s existing and future subsidiaries that incur or guarantee certain indebtedness, including indebtedness under the Revolver. The Indenture contains covenants that restrict the Company’s ability and the ability of certain of its subsidiaries to, among other restrictions and limitations: (i) incur additional indebtedness; (ii) incur liens; (iii) pay dividends; (iv) consolidate, merge, or transfer all or substantially all of its or their assets; (v) engage in transactions with affiliates; or (vi) engage in certain restricted business activities.  These covenants are subject to a number of exceptions and qualifications.


Capital Expenditures

Capital expenditures for drilling and completion activities totaled $408.3$110.2 million and $383.0$111.0 million for the ninethree months ended September 30,March 31, 2019 and 2018, and 2017, respectively.

During the ninethree months ended September 30, 2018,March 31, 2019, we drilled 8928 operated horizontal wells and turned 5433 operated horizontal wells to sales. As of September 30, 2018,March 31, 2019, the Company had 918 gross (8(16 net) wells that were drilled and completed, but not producing. These wells are expected to be turned to sales during the fourthsecond quarter. As of September 30, 2018,March 31, 2019, we are the operator of 7766 gross (66(56 net) horizontal wells in progress, which excludes 30 gross (23 net) wells for which we have only set surface casings.progress. All of the wells in progress at September 30, 2018March 31, 2019 are scheduled to commence production before December 31, 2019.2020. The majority of this activity was funded through cash flows from operations.

For the ninethree months ended September 30, 2018,March 31, 2019, we participated in 6124 gross (14(2 net) non-operated horizontal wells.

Capital Requirements

Our level of exploration, development, and acreage expenditures is largely discretionary, and the amount of funds devoted to any particular activity may increase or decrease significantly depending on available opportunities, commodity prices, cash flows, development results, acquisitions and divestitures, and downstream infrastructure and commitments, among other factors. Our primary need for capital will be to fund our anticipated drilling and completion activities and any other acquisitions that we may complete during 2018.2019.

We anticipate that our full-year 20182019 capital expenditures, including operated drilling and completion capital expenditures for operated wellscosts, limited leasehold acquisition costs and selected non-operated drilling and completion costs, will be approximately $580between $425 million ($408.3 million of which was incurred through September 30, 2018).and $450 million. However, should commodity prices and/or economic conditions change, we can reduce or accelerate our drilling and completion activities depending on midstream constraints, which could have a material impact on our anticipated capital requirements.

For the near term, we believe that we have sufficient liquidity to fund our needs through cash on hand, cash flow from operations, and additional borrowings available under our revolving credit facility.  However, should this not meet all of our long-term needs, we may need to raise additional funds to drill new wells through the sale of our securities, from third parties willing to pay our share of drilling and completing wells, or from other sources.  We may not be successful in raising the capital needed to drill or acquire oil or natural gas wells. We may seek to raise funds in capital markets transactions from time to time if we believe market conditions to be favorable.


Oil and Natural Gas Commodity Contracts

We use derivative contracts to help protect against the variability in cash flows created by short-term price fluctuations associated with the sale of future oil and natural gas production.  At October 23, 2018,March 31, 2019, we had open positions covering 3.13.0 million barrels of oil and 15,380 M16.5 BMcfcf of natural gas. We do not use derivative instruments for speculative purposes.

Our commodity derivative instruments may include but are not limited to “collars,” “swaps,” and “put” positions. Our derivative strategy, including the volumes and commodities covered and the relevant strike prices, is based in part on our view of expected future market conditions and our analysis of well-level economic return potential. In addition, our use of derivative contracts is subject to stipulations set forth in our credit facility.


During the ninethree months ended September 30, 2018,March 31, 2019, we reported an unrealized commodity activity loss of $12.4$27.8 million.  Unrealized losses are non-cash items.  We also reported a realized lossgain of $16.2$4.9 million, representing the settlement of commodity contracts settled during the period.

At September 30, 2018,March 31, 2019, we estimated that the fair value of our various commodity derivative contracts was a net liabilityasset of $20.2$7.1 million. See Item 1. Financial Statements – Note 9,8, Fair Value Measurements, for a description of the methods we use to estimate the fair values of commodity derivative instruments.

Non-GAAP Financial MeasuresMeasure

In addition to financial measures presented on the basis of accounting principles generally accepted in the United States of America ("US GAAP"), we present certain financial measures which are not prescribed by US GAAP ("non-GAAP"). The following is a summary of the measure that we currently report.

Adjusted EBITDA

We use "adjusted EBITDA," a non-GAAP financial measure, for internal managerial purposes because it allows us to evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed in the table below from net income in arriving at adjusted EBITDA. We exclude those items because they can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures, and the method by which the assets were acquired. Adjusted EBITDA is not a measure of financial performance under US GAAP and should be considered in addition to, not as a substitute for, net income. We believe that adjusted EBITDA is widely used in our industry as a measure of operating performance and may also be used by investors to measure our ability to meet debt covenant requirements. However, our definition of adjusted EBITDA may not be fully comparable to measures with similar titles reported by other companies. We define adjusted EBITDA as net income adjusted to exclude the impact of the items set forth in the table below (amounts in(in thousands):

Critical Accounting Policies

We prepare our condensed consolidated financial statements and the accompanying notes in conformity with US GAAP, which requires management to make estimates and assumptions about future events that affect the reported amounts in the condensed

consolidated financial statements and the accompanying notes. We identify certain accounting policies as critical based on, among other things, their impact on the portrayal of our financial condition, results of operations, or liquidity and the degree of difficulty, subjectivity, and complexity in their deployment. Critical accounting policies cover accounting matters that are inherently uncertain because the future resolution of such matters is unknown. Management discusses the development, selection, and disclosure of each of the critical accounting policies.

There have been no significant changes to our critical accounting policies and estimates or in the underlying accounting assumptions and estimates used from those disclosed in the "Management’s Discussion and Analysis of Financial Condition and Results of Operations" section of the Annual Report on Form 10-K filed with the SEC on February 21, 201820, 2019 and in the financial

statements and accompanying notes contained in that report. Item 1. Financial Statements – Note 1, Organization and Summary of Significant Accounting Policies, to the accompanying condensed consolidated financial statements included elsewhere in this report provides information regarding recently issued accounting pronouncements.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS

Commodity Price Risk - Our financial condition, results of operations, and capital resources are highly dependent upon the prevailing market prices of oil and natural gas. The volatility of oil prices affects our results to a greater degree than the volatility of natural gas prices, as approximately 77%78% of our revenue during the three and nine months ended September 30, 2018March 31, 2019 was from the sale of oil. A $5 per barrel change in our realized oil price would have resulted in a $9.6 million and $29.0$14.8 million change in revenues during the three and nine months ended September 30, 2018, respectively;March 31, 2019; a $0.25 per Mcf change in our realized natural gas price would have resulted in a $2.4 million and $6.5$2.8 million change in our natural gas revenues for the three and nine months ended September 30, 2018, respectively;March 31, 2019; and a $5 per barrel change in our realized NGL price would have resulted in a $5.2 million and $13.9$5.3 million change in our NGL revenues for the three and nine months ended September 30, 2018, respectively.March 31, 2019.

During the three months ended September 30, 2018,March 31, 2019, the price of oil, natural gas, and NGLs increaseddecreased relative to the secondfourth quarter of 2018.  These commodity prices are subject to wide fluctuations and market uncertainties due to a variety of factors that are beyond our control. Factors influencing oil, natural gas, and NGL prices include the levels of demand and supply for oil (in global or local markets), the establishment of and compliance with production quotas by oil exporting countries, weather conditions which influence the demand for natural gas, the price and availability of alternative fuels, the strength of the US dollar compared to other currencies, and overall economic conditions. It is impossible to predict future oil, natural gas, and NGLs prices with any degree of certainty. Sustained weakness in oil, natural gas, and NGL prices may adversely affect our financial condition and results of operations and may also reduce the amount of oil, natural gas, and NGL reserves that we can produce economically. Any reduction in our oil, natural gas, and NGL reserves, including reductions due to price fluctuations, can have an adverse effect on our ability to obtain capital for our exploration and development activities.  Similarly, any improvements in oil, natural gas, and NGL prices can have a favorable impact on our financial condition, results of operations, and capital resources.

We attempt to mitigate fluctuations in short-term cash flow resulting from changes in commodity prices by entering into derivative positions on a portion of our expected oil and natural gas production.  Under the Revolver, we can use derivative contracts to cover up to 85% of expected proved developed producing production as projected in our semi-annual reserve report, generally over a period of two years.  We do not enter into derivative contracts for speculative or trading purposes. As of September 30, 2018,March 31, 2019, we had open oil and natural gas derivatives in a net liabilityasset position with a fair value of $20.2$7.1 million.  A hypothetical upward shift of 10% in the NYMEX forward curve of oil and natural gas prices would decrease the fair value of our position by $16.1$11.7 million. A hypothetical downward shift of 10% in the NYMEX forward curve of oil and natural gas prices would increase the fair value of our position by $7.8$14.8 million.

Interest Rate Risk - At September 30, 2018,March 31, 2019, we had $115.0$195.0 million outstanding under our revolving credit facility.  Interest on amounts borrowed under our credit facility accrues at a variable rate, based upon either the Prime Rate or LIBOR plus an applicable margin.  During the three and nine months ended September 30, 2018,March 31, 2019, we incurred interest expense of $0.4 million and $0.5$2.2 million on our revolving credit facility, respectively.facility. When we have balances outstanding under the revolving credit facility, we are exposed to interest rate risk if the variable reference rates increase. If interest rates increase, our interest payments would increase and our available cash flow would decrease.  We estimate that if market interest rates increased or decreased by 1%, our interest expense in the three and nine months ended September 30, 2018March 31, 2019 would have changed by approximately $0.1$0.5 million.

Under current market conditions, we do not anticipate significant changes in prevailing interest rates for the next year, and we have not undertaken any activities to mitigate potential interest rate risk due to restrictions imposed by the Revolver.

Counterparty Risk - As described in "Commodity Price Risk" above, we enter into commodity derivative agreements to mitigate short-term price volatility.  These derivative financial instruments present certain counterparty risks.  We are exposed to potential loss if a counterparty fails to perform according to the terms of the agreement. The failure of any of the counterparties to fulfill their obligations to us could adversely affect our results of operations and cash flows.  We do not require collateral or other security to be furnished by counterparties.  We seek to manage the counterparty risk associated with these contracts by limiting transactions to well-capitalized, well-established, and well-known counterparties that have been approved by our senior officers.  There can be no assurance, however, that our practice effectively mitigates counterparty risk. 

We believe that our exposure to counterparty risk increaseddecreased slightly during the thirdfirst quarter of 20182019 as the amounts due to us from counterparties have increased.decreased.



ITEM 4.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") as of the end of the period covered by this report on Form 10-Q (the "Evaluation Date").  Based on such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.


PART II

Item 1.Legal Proceedings

During the quarter ended September 30, 2018,March 31, 2019, there were no material developments regarding the legal matters, previously described under Item 3, Legal Proceedings, of the Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 21, 2018.20, 2019. This information should be considered carefully together with other information in this report and other reports and materials we file with the SEC. We are subject to various legal proceedings from time to time in the ordinary course of our business, but there are currently no pending legal proceedings to which we are subject that we believe to be material.

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 the Annual Report on Form 10-K filed with the SEC on February 21, 2018.20, 2019. This information should be considered carefully together with other information in this report and other reports and materials that we file with the SEC.

Proposition 112, if approved, would have a material adverse effect on our future drilling inventory and other aspects of our business.

Proposition 112 is a proposed statutory amendment that will be voted on in Colorado in November 2018. Proposition 112 would require all new oil and gas development facilities to be located at least 2,500 feet away from any occupied structure or “vulnerable areas,” a term defined to include playgrounds, permanent sports fields, amphitheaters, public parks, public open space, public and community drinking water sources, irrigation canals, reservoirs, lakes, rivers, perennial or intermittent streams and creeks and any additional areas designated by the state or a local government. Proposition 112 would not apply to federal lands. If implemented, Proposition 112 would have a variety of adverse effects on our business. In particular, the expanded setback requirement (current law generally requires a setback between oil and gas wells and occupied structures of 500 feet) would make it unlawful to drill many of our currently planned locations, and would limit our ability to add drilling locations to our inventory in the future. The Colorado Oil and Gas Conservation Commission has estimated that Proposition 112 would make drilling unlawful on approximately 85 percent of the non-federal surface area of the state of Colorado, including approximately 85 percent of the non-federal surface area of Weld County. The remaining land available for drilling would likely be reduced over time as additional occupied structures are built and additional areas are designated as vulnerable. Proposition 112’s limitation on our existing and potential future locations would significantly restrict our opportunities for growth and, over time, would likely have a materially adverse effect on our results of operations, financial condition and ability to attract capital.

The implementation of Proposition 112 could have other potential adverse effects on our business, including, but not limited to:
additional constraints on midstream capacity if midstream infrastructure and services are not expanded as currently expected,
increased operating costs,
greater difficulties in maintaining leases through production,
increased expenses related to legal, regulatory, or legislative actions that we may pursue in response to the implementation of the proposition, and
inability to meet commitments related to our future production.

Finally, even if Proposition 112 is not approved, we expect that some political leaders will propose new regulations to restrict oil and natural gas development activities by other means in an attempt to address concerns underlying the proposition. We cannot predict the outcome of any such proposals, but they could have material and adverse effects on our business.
