Explanatory Note

We are filing this Amendment No. 1 on Form 10-Q/A (the Amended Filing or Form 10-Q/A) to our previously issued Quarterly Report on Form 10-Q for the quarter ended March 31, 2018, initially filed with the Securities and Exchange Commission on May 3, 2018 (the Original Filing). This Form 10-Q/A amends and restates Items 1, 2, and 4 of Part I of the Original Filing.

In the course of preparing our consolidated financial statements for the quarter ended June 30, 2018, we identified a misstatement as of March 31, 2018, of approximately $44.9 million within the operating activities and the investing activities sections of the statement of cash flows. Management reported the matter to the Audit Committee of the Company's Board of Directors.

The misstatement did not have any impact on revenues, net income, working capital, total assets, or shareholders' equity. Our financial statements have been restated to correctly reflect the noncash activity within our condensed consolidated statements of cash flows. We have restated Note 1, Basis of Preparation and Presentation to reflect the impacts of this correction to the statement of cash flows.

Correspondingly, this Form 10-Q/A amends and restates Item 2 of Part I, which includes our revised discussion of liquidity and capital resources to reflect the impact of the restatement to the statement of cash flows. Item 4 of Part I includes our revised assessment of the effectiveness of our disclosure controls and procedures. This restatement resulted from a material weakness in internal control over financial reporting. In addition, under the rules of the SEC, Item 6 of Part II of the Original Filing has been amended to contain currently-dated certifications from our Chief Executive Officer and Chief Financial Officer, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002.

This Form 10-Q/A has not been updated for events occurring after the filing of the Original Filing, except to reflect the foregoing.

Forward-Looking Statements

This report contains “forward-looking statements” – meaning, statements related to future events within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included or incorporated by reference in this document that addresses activities, events or developments we expect or anticipate will or may occur, are forward-looking statements. The words “believes,” “intends,” “expects,” “anticipates,” “projects,” “estimates,” “predicts,” and similar expressions are used to identify forward-looking statements. This report modifies and supersedes documents filed by us before this report. In addition, certain information we file with the SEC will automatically update and supersede information in this report.
 
These forward-looking statements include, among others, things as:

the amount and nature of our future capital expenditures and how we expect to fund our capital expenditures;
prices for oil, natural gas liquids (NGLs), and natural gas;
demand for oil, NGLs, and natural gas;
our exploration and drilling prospects;
the estimates of our proved oil, NGLs, and natural gas reserves;
oil, NGLs, and natural gas reserve potential;
development and infill drilling potential;
expansion and other development trends of the oil and natural gas industry;
our business strategy;
our plans to maintain or increase production of oil, NGLs, and natural gas;
the number of gathering systems and processing plants we plan to construct or acquire;
volumes and prices for natural gas gathered and processed;
expansion and growth of our business and operations;
demand for our drilling rigs and drilling rig rates;
our belief that the final outcome of legal proceedings involving us will not materially affect our financial results;
our ability to timely secure third-party services used in completing our wells;
our ability to transport or convey our oil or natural gas production to established pipeline systems;

ii

Table of Contents

impact of federal and state legislative and regulatory actions affecting our costs and increasing operating restrictions or delays and other adverse impacts on our business;
our projected production guidelines for the year;
our anticipated capital budgets;
our financial condition and liquidity;
the number of wells our oil and natural gas segment plans to drill or rework during the year;
our intended use of the proceeds from the sale of 50% of the interest we owned in our midstream segment; and
our estimates of the amounts of any ceiling test write-downs or other potential asset impairments we may have to record in future periods.
These statements are based on assumptions and analyses made by us based on our experience and our perception of historical trends, current conditions, and expected future developments, and other factors we believe are appropriate in the circumstances. Whether actual results and developments will conform to our expectations and predictions is subject to several risks and uncertainties, any one or combination of which could cause our actual results to differ materially from our expectations and predictions, including:
the risk factors discussed in this document and in the documents (if any) we incorporate by reference;
general economic, market, or business conditions;
the availability of and nature of (or lack of) business opportunities we pursue;
demand for our land drilling services;
changes in laws or regulations;
changes in the current geopolitical situation;
risks relating to financing, including restrictions in our debt agreements and availability and cost of credit;
risks associated with future weather conditions;
decreases or increases in commodity prices;
putative class action lawsuits that may result incause substantial expenditures and divert management's attention; and
other factors, most of which are beyond our control.
You should not place undue reliance on these forward-looking statements. Except as required by law, we disclaim any intention to update forward-looking information and to release publicly the results of any future revisions we may make to forward-looking statements to reflect events or circumstances after the date of this document to reflect unanticipated events.

Our financial statements are prepared in conformity with generally accepted accounting principles in the United States (GAAP). GAAP requires us to make certain estimates and assumptions that may affect the amounts reported in our unaudited condensed consolidated financial statements and notes. Actual results may differ from those estimates. Results for the sixthree months ended June 30, 2017March 31, 2018 and 20162017 are not necessarily indicative of the results to be realized for the full year of 20172018, or that we realized for the full year of 20162017.

Certain amounts in theRestatement of Unaudited Condensed Consolidated Statement of Cash Flows

We have restated our unaudited condensed consolidated financial statements to correct an error within our condensed consolidated statement of cash flows. In the course of preparing our consolidated financial statements for prior periods have been reclassifiedthe quarter ended June 30, 2018, we identified an error as of March 31, 2018, of approximately $44.9 million between the operating activities and the investing activities sections of the statement of cash flows. The following table presents the effect of the correction on the selected line items previously reported in the condensed consolidated cash flows statement for the three months ended March 31, 2018:

Accounting Changes - Recent Accounting Pronouncements - Adopted

As of January 1, 2018, the company adopted ASU 2018-02 Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This standard is explained further in Note 8 - New Accounting Pronouncements. We adopted this amendment early and it did not have a material effect to our financial statements. We previously used 37.75% to calculate the tax effect on AOCI and now we are using 24.5%. The change is reflected in our Unaudited Condensed Consolidated Statements of Comprehensive Income and in Note 13 - Equity.

Also, as of January 1, 2018, the company adopted ASU 2014-09 Revenue from Contracts with Customers - Topic 606 (ASC 606) and all later amendments that modified ASC 606. The new revenue standard is explained further in Note 8 - New Accounting Pronouncements. The company has elected to apply the standard on the modified retrospective approach method to contracts not completed as of January 1, 2018, where the cumulative effect upon adoption, which only impacted our mid-stream segment is recognized as an adjustment to opening retained earnings at January 1, 2018. This adjustment related to the timing of revenue recognition for certain demand fees. Both our oil and natural gas and contract drilling segments had no retained earnings adjustment. Comparative prior periods have not been adjusted and continue to be reported under ASC 605.

The additional disclosures required by the ASU have been included in Note 2 – Revenue from Contracts with Customers.

NOTE 2 – OIL AND NATURAL GAS PROPERTIESREVENUE FROM CONTRACTS WITH CUSTOMERS

Full cost accounting rules require us to reviewThe company’s revenue streams are reported under three segments: oil and natural gas, contract drilling, and mid-stream. This is our disaggregation of revenue and how our segment revenue is reported (as reflected in Note 14 - Industry Segment Information). Revenue from the carrying valueoil and natural gas segment is derived from sales of our oil and natural gas propertiesproduction. Revenue from the contract drilling segment is derived by contracting with upstream companies to drill an agreed-on number of wells or provide drilling rigs and services over an agreed-on period of time. Revenue from the mid-stream segment is derived from gathering, transporting, and processing natural gas production and selling those commodities. The company sells its hydrocarbons (from the oil and natural gas and mid-stream segments) to midstream and downstream oil and gas companies.

We satisfy performance obligation for each contract as follows: for the contract drilling and mid-stream contracts, we satisfy the performance obligation over the agreed-on time period within the contracts, and for oil and natural gas contracts, we satisfy the performance obligation with each delivery of volumes. For oil and natural gas contracts, as it is more feasible, we account for these deliveries on a monthly basis. Per the contracts for all segments, customers pay for the services/goods received on a monthly basis within an agreed on number of days following the end of the month. Besides the mid-stream demand fees discussed further below, there were no other contract assets or liabilities.

Oil and Natural Gas Contracts, Revenues, Implementation Impact to Retained Earnings, and Performance Obligations

Typical types of revenue contracts signed are Oil Sales Contracts, Gas Purchase Agreements, North American Energy Standards Board (NAESB) Contracts, Gas Gathering and Processing Agreements, and revenues earned as the non-operated party with the operator serving as an agent on our behalf under our Joint Operating Agreements. Contract term can range from single month to extended term contracts spanning a decade or more; some include evergreen provisions. Revenues from sales are recognized when the customer obtains control of the company’s product. For sales to other midstream and downstream oil and gas companies, this would occur at a point in time, typically on delivery to the customer. Sales generated from our non-operated interest are recorded based on the information obtained from the operator. On adoption of the standard, no adjustment to opening retained earnings was required.


Certain costs as either a deduction from revenue or an expense is determined based on when control of the commodity transfers to the customer, which would affect our total revenue recognized, but will not affect gross profit. For example, gathering, processing and transportation costs that are included as part of the contract price with the customer upon transfer of control of the commodity are included in the transaction price, while costs incurred while we are in control of the commodity represent operating costs. The following table summarizes the impact of the adoption of ASC 606 on revenue and operating costs, as the change did not impact income from operations or net income for the three months ended March 31, 2018:
  As Reported Adjustments due to ASC 606 Amounts without the Adoption of ASC 606

Oil and natural gas operating costs 35,962
 (3,169) 39,131
Gross profit $67,137

 $67,137

Our performance obligation for all contracts is the delivery of oil and gas volumes to the customer. Typically the contract will establish a period of time (for example, a month or a year); however, each delivery can be considered separately identifiable as each delivery provides benefits to the customer on its own. For feasibility, as accounting for a monthly performance obligation is not materially different than identifying a more granular performance obligation, we conclude this performance obligation is satisfied monthly. We typically receive payment within a set number of days following the end of the month and includes payment for all deliveries in that month. Depending on contract circumstances, judgment could be required to determine when the transfer of control occurs. Generally, depending of the facts and circumstances, we consider the transfer of control of the asset in a commodity sale to occur at the point the commodity transfers to our final purchaser.

The majority of the consideration received for oil and gas sales is variable. Most of our contracts state the consideration is calculated by multiplying a variable quantity by an agreed-on index price less deductions related to gathering, transportation, fractionation, and related fuel charges. There are also instances where the consideration is quantity multiplied by a weighted average sales price. These different pricing tools can change the perception of when control transfers; however, when analyzed with other control factors, typically the accounting conclusion is the same for both pricing methods. In these instances, the variable consideration is partially constrained. In addition, all variable consideration is settled at the end of the month; therefore, whether the variability is constrained does not affect accounting for revenue under ASC 606 as the variability is known prior to each reporting period. An estimation and allocation of transaction price and future obligations are not required.

Contract Drilling Contracts, Revenues, Implementation impact to retained earnings, and Performance Obligations

The contract drilling contracts we use primarily are industry standard IADC contracts 2003 and 2013. Contract terms can range from six months to two or more years or can be based on terms to drill a specific number of wells. These allocation rules in ASC 606 are referred to as the series guidance which states that a contract may contain a single performance obligation composed of a series of distinct goods or services if 1) each distinct good or service is substantially the same and would meet the criteria to be a performance obligation satisfied over time and 2) each distinct good or service is measured using the same method as it relates to the satisfaction of the overall performance obligation. The company determined that the delivery of drilling services is within the scope of the series guidance as both criteria noted above are met. Specifically, 1) each distinct increment of service (i.e. hour available to drill) that the driller promises to transfer represents a performance obligation that would meet the criteria for recognizing revenue over time, and 2) the driller would use the same method for measuring progress toward satisfaction of the performance obligation for each distinct increment of service in the series. At inception, the total transaction price will be estimated to include any applicable fixed consideration, unconstrained variable consideration (estimated day rate mobilization and demobilization revenue, estimated operating day rate revenue to be earned over the contract term, expected bonuses (if material and can be reasonably estimated without significant reversal), and penalties (if material and can be reasonably estimated without significant reversal)). Allocation rules under the new standard will allow the company to recognize revenues associated with contract drilling contacts in materially the same manner as under the previous revenue accounting standard. A contract liability will be recorded for consideration received before the corresponding transfer of services. Such liabilities will generally only arise in relation to upfront mobilization fees which are paid in advance and are allocated/recognized over the entire performance obligation. Such balances will be amortized over the recognition period based on the same method of measure used for revenue. On adoption of the standard, no adjustment to opening retained earnings was required.


Our performance obligation for all contracts is to drill the agreed-on number of wells or drill over an agreed-on period of time as stated in the contract. Mobilization and demobilization activities associated with a drilling contract are not considered to be distinct within the context of the contract and therefore, any associated revenue is allocated to the overall performance obligation of drilling services and recognized ratably over the initial term of the related drilling contract. It typically takes from 10 to 90 days to complete drilling a well; therefore, depending on the number of wells under a contract, the contract term could be up to two years. Most of the drilling contracts are for less than one year. As the customer simultaneously received and consumes the benefits provided by the company’s performance, and the company’s performance enhances an asset that the customer controls, the performance obligation to drill the well occurs over time. We typically receive payment within a set number of days following the end of the month and includes payment for all services performed that month (calculated on an hourly basis). The company satisfies its overall performance obligation when the well included in the contract is drilled to an agreed-upon depth or by a set date.

All consideration received for contract drilling contracts is variable, excluding termination fees, which we concluded will not be applicable to our current contracts as of the reporting date. The consideration is calculated by multiplying a variable quantity (number of days/hours) by an agreed-on daily price (for the daily rate, mobilization and demobilization revenue). Other revenue items per the contract include bonus/penalty revenue, reimbursable revenue, drilling fluid rates, and early termination fees. All variable consideration is not constrained but is settled at the end of the month; therefore, whether or not the variability is constrained does not affect accounting for revenue under ASC 606 as the variability is known prior to each reporting period excluding certain bonuses/penalties which might be based on activity that occurs over the entire term of the contract. We have evaluated the mobilization and de-mobilization charges on outstanding contracts, however, the impact to the financial statements was immaterial. As of March 31, 2018, we had 32 contract drilling contracts (six long-term) for a duration of two to fourteen months.

Per the new guidance in relation to disclosures regarding remaining performance obligations, there is a practical expedient for contracts that have an original expected duration of one year or less (ASC 606-10-50-14) and for contracts where the entity can recognize revenue as invoiced (ASC 606-10-55-18). The majority of contract drilling contracts have an original term of less than one year; however, there are a few contracts with a longer duration that are not material.

Mid-stream Contracts Revenues, and Implementation impact to retained earnings, and Performance Obligations

Revenues are generated from the fees earned for gas gathering and processing services provided to a customer. Typical types of revenue contracts signed are Gas Gathering and Processing agreements. Contract terms can range from single month to extended term contracts spanning a decade or more, some include evergreen provisions. Fees for mid-stream services (gathering, transportation, processing) are performance obligations and meet the criteria of over time recognition which could be considered a series of distinct performance obligations that represents one overall performance obligation of gas gathering and processing services.

On adoption of the standard, an adjustment to opening retained earnings was made in the amount of $1.7 million ($1.3 million, net of tax). This adjustment related to the timing of revenue recognized on certain demand fees and had the following impact to the Unaudited Condensed Consolidated Balance Sheet:

The only fixed consideration related to mid-stream consideration is the demand fee which is calculated by multiplying an agreed-on price by a fixed number of volumes per month over a specified term in the contract.

Before the implementation of ASC 606, we recognized the entire demand fee as the fee was payable the first five years after the effective date, not the entire term of the contract. However, as the demand fee does not specifically relate to a distinct performance obligation, the amount should be recognized over the life of the contract. Therefore, the demand fee already recognized for $1.7 million ($1.3 million, net of tax) was adjusted to retained earnings as of January 1, 2018, and will be recognized over the remaining term of the contract. As this amount is fixed consideration, recognition of the remaining portion will be stable. For the first three months of March 31, 2018, $1.2 million was recognized in revenue for these demand fees.


Besides the demand fee, there were no other contract assets or liabilities (see above for the balance sheet line items where they are reported.)

Our performance obligations for all contracts is to gather, transport, or process an agreed-on number of volumes as stated in the contract. Typically the contract will establish a period of time over which the company will perform the mid-stream services. Certain contracts also include an agreed-on quantity (or an agreed-on minimum quantity) of volumes that the company will deliver or service. The term under mid-stream service contracts is typically five to ten years. Under service contracts, as the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs, the performance obligation to gather, transport, or process occurs over time. We typically receive payment within a set number of days following the end of the month and includes payment for all services performed that month. The company satisfies its overall performance obligation at the end of the contract term.

Most of the consideration received for mid-stream service contracts is variable. The consideration is calculated by multiplying a variable quantity (number of volumes) by an agreed-on price per MCF (commodity fee and the gathering fee). One fixed component of revenue is calculated by multiplying an agreed-on price by a certain volume commitment (MCF per day). Other revenue items may include shortfall fees. All variable consideration is settled at the end of the month; therefore, whether or not the variability is constrained does not affect accounting for revenue under ASC 606 as the variability is known before each reporting period. However, this excludes the shortfall fee as this fee could be based on a set number of volumes over the course of more than one month.

Per the new guidance related to disclosures for remaining performance obligations, there is a practical expedient for contracts that have an original expected duration of one year or less (ASC 606-10-50-14). There is also a practical expedient for “variable consideration [that] is allocated entirely to a wholly unsatisfied performance obligation… that forms part of a single performance obligation… for which the criteria in paragraph 606-10-32-40 have been met” (ASC 606-10-50-14A). As stated previously, the contract term for mid-stream services is typically longer than one year. However, based on the guidance at 606-10-32-40, we determined some of the variable payment in mid-stream service agreements specifically relates to the entity’s efforts to satisfy the performance obligation and that “allocating the variable amount entirely to the distinct good or service is consistent with the allocation objective in paragraph 606-10-32-28.” Therefore, the practical expedient relates to this variable consideration: the commodity fee and the gathering fee. The last time we received a shortfall fee was in 2016 and the amount was immaterial to total mid-stream revenues. These terms have historically been limited in our contracts.

We calculate revenue earned from the variable consideration related to mid-stream services by multiplying the number of volumes serviced times an agreed-on price. Therefore, the variable portion of this consideration is due to the change in volumes. This variability is resolved at the end of each quarter. Under those rules, the maximum amount allowedmonth as the carrying valuecompany will know the number of volumes serviced under each contract and payment is referredreceived monthly. The mid-stream gathering service contracts remaining are for a duration of less than one year to 15 years.

While long term service contracts are in place as the ceiling. The ceiling is the sum of the present value (using a 10% discount rate)reporting date, due to the variable volumes an estimation and allocation of the estimatedtransaction price and future net revenues from our proved reserves (using the unescalated 12-month average price of our oil, NGLs, and natural gas), plus the cost of propertiesobligations are not being amortized, plus the lower of cost or estimated fair value of unproved properties included in the costs being amortized, less related income taxes. If the net book value of the oil, NGLs, and natural gas properties being amortized exceeds the full cost ceiling, the excess amount is charged to expense in the period during which the excess occurs, even if prices are depressed for only a short while. Once incurred, a write-down of oil and natural gas properties is not reversible.

During the first and second quarter of 2016, we had a non-cash ceiling test write-down of $37.8 million pre-tax ($23.5 million, net of tax) and $74.3 million pre-tax ($46.3 million, net of tax), respectively. We had no non-cash ceiling test write-downs for the first or second quarter of 2017.required.

NOTE 3 – ACQUISITIONS AND DIVESTITURES

Acquisitions

On April 3, 2017, we closed on an acquisition of certain oilOil and natural gas assets located primarily in Grady and Caddo Counties in western Oklahoma. The preliminary adjusted value of consideration given was $54.0 million.

As of January 1, 2017, the effective date of the acquisition, the estimated proved oil and gas reserves of the acquired properties were 3.2 million barrels of oil equivalent (MMBoe). The acquisition adds approximately 8,300 net oil and gas

leasehold acres to our core Hoxbar area in southwestern Oklahoma including approximately 47 proved developed producing wells. Of the acreage acquired, approximately 71% is held by production. We also received one gathering system as part of the transaction.

We accounted for this acquisition using the acquisition method under ASC 805, Business Combinations, which requires that the acquired assets and liabilities be recorded at their fair values as of the acquisition date. The following table summarizes the preliminary purchase price and the preliminary estimated values of assets acquired and liabilities assumed. It is based on information available to us at the time these unaudited condensed consolidated financial statements were prepared. We believe these estimates are reasonable; however, the estimates are subject to change as additional information becomes available and is assessed by us (in thousands):

The pro forma effects of this acquired business is immaterial to the results of operations.

DivestituresNatural Gas

We sold non-core oil and natural gas assets, net of related expenses, for $17.8$21.7 million during the first sixthree months of 2017,2018, compared to $43.6$14.8 million during the first sixthree months of 2016.2017. Proceeds from those sales reduced the net book value of our full cost pool with no gain or loss recognized.

Credit Agreement. OurOn April 2, 2018, we amended our Senior Credit Agreement (credit agreement) is scheduled to mature on April 10, 2020. UnderThe details of this amendment are discussed in Note 15 — Subsequent Events.

Before the credit agreement,amendment and through March 31, 2018, the amount we cancould borrow iswas the lesser of the amount we elect as the commitment amount or the value of the borrowing base as determined by the lenders, but in either event not to exceed $875.0 million. Our borrowing base and elected commitment amount is $475.0 million. Our borrowing base iswas $475.0 million. We arewere charged a commitment fee of 0.50% on the amount available but not borrowed. That fee variesvaried based on the amount borrowed as a percentage of the total borrowing base. We paid $1.0 million in origination, agency, syndication, and other related fees. We are amortizing these fees over the life of the credit agreement. Under the credit agreement, we have pledged the following collateral: (a) 85% of the proved developed producing (discounted as present worth at 8%) total value of our oil and gas properties and (b) 100% of our ownership interest in our midstreammid-stream affiliate, Superior Pipeline Company, L.L.C.

The borrowing base amount–which is subject to redetermination by the lenders on April 1st and October 1st of each year–is based primarily on a percentage of the discounted future value of our oil and natural gas reserves. We or the lenders may request a onetime special redetermination of the borrowing base between each scheduled redetermination. In addition, we may request a redetermination following the completion of an acquisition that meets the requirements in the credit agreement.

At our election, any part of the outstanding debt under the credit agreement maycould be fixed at a London Interbank Offered Rate (LIBOR). LIBOR interest is computed as the LIBOR base for the term plus 2.00% to 3.00% depending on the level of debt as a percentage of the borrowing base and is payable at the end of each term, or every 90 days, whichever is less. Borrowings not under LIBOR bear interest at the prime rate specified in the credit agreement that cannot be less than LIBOR plus 1.00% plus a margin. Interest is payable at the end of each month and the principal may be repaid in whole or in part at any time, without a premium or penalty. At June 30, 2017,March 31, 2018, we had $164.9$147.7 million of outstanding borrowings under our credit agreement.

We can use borrowings for financing general working capital requirements for (a) exploration, development, production, and acquisition of oil and gas properties, (b) acquisitions and operation of mid-stream assets, (c) issuance of standby letters of credit, (d) contract drilling services and acquisition of contract drilling equipment, and (e) general corporate purposes.

The credit agreement prohibits, among other things:

the payment of dividends (other than stock dividends) during any fiscal year over 30% of our consolidated net income for the preceding fiscal year;
the incurrence of additional debt with certain limited exceptions; and
the creation or existence of mortgages or liens, other than those in the ordinary course of business and with certain limited exceptions, on any of our properties, except in favor of our lenders.


The credit agreement also requires that we have at the end of each quarter:

a current ratio (as defined in the credit agreement) of not less than 1 to 1.

Through the quarter ending March 31, 2019, the credit agreement also requires that we have at the end of each quarter:

a senior indebtedness ratio of senior indebtedness to consolidated EBITDA (as defined in the credit agreement) for the most recently ended rolling four quarters of no greater than 2.75 to 1.

Beginning with the quarter ending June 30, 2019, and for each following quarter, the credit agreement requires:

a leverage ratio of funded debt to consolidated EBITDA (as defined in the credit agreement) for the most recently ended rolling four fiscal quarters of no greater than 4 to 1.

As of June 30, 2017March 31, 2018, we were in compliance with the credit agreement covenants.

6.625% Senior Subordinated Notes. We have an aggregate principal amount of $650.0 million, 6.625% senior subordinated notes (the Notes) outstanding. Interest on the Notes is payable semi-annually (in arrears) on May 15 and November 15 of each year. The Notes mature on May 15, 2021. In issuing the Notes, we incurred fees of $14.7 million that are being amortized as debt issuance cost over the life of the Notes.

The Notes are subject to an Indenture dated as of May 18, 2011, between us and Wilmington Trust, National Association (successor to Wilmington Trust FSB), as Trustee (the Trustee), as supplemented by the First Supplemental Indenture dated as of May 18, 2011, between us, the Guarantors, and the Trustee, and as further supplemented by the Second Supplemental Indenture dated as of January 7, 2013, between us, the Guarantors, and the Trustee (as supplemented, the 2011 Indenture), establishing the terms of and providing for issuing the Notes. The Guarantors are most of our direct and indirect subsidiaries. The discussion of the Notes in this report is qualified by and subject to the actual terms of the 2011 Indenture.

Unit, as the parent company, has no independent assets or operations. The guarantees by the Guarantors of the Notes
(registered under registration statements) are full and unconditional, joint and several, subject to certain automatic customary releases, are subject to certain restrictions on the sale, disposition, or transfer of the capital stock or substantially all of the assets of a subsidiary guarantor, and other conditions and terms set out in the 2011 Indenture. Any of our subsidiaries that are not Guarantors are minor. There are no significant restrictions on our ability to receive funds from any of our subsidiaries through dividends, loans, advances, or otherwise.

We may redeem all or, occasionally, a part of the Notes at certain redemption prices, plus accrued and unpaid interest. If a “change of control” occurs, subject to certain conditions, we must offer to repurchase from each holder all or any part of that holder’s Notes at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest to the date of purchase. The 2011 Indenture contains customary events of default. The 2011 Indenture also contains covenants including those that limit our ability and the ability of certain of our subsidiaries to incur or guarantee additional indebtedness; pay dividends on our capital stock or redeem capital stock or subordinated indebtedness; transfer or sell assets; make investments; incur liens; enter into transactions with our affiliates; and merge or consolidate with other companies. We were in compliance with all covenants of the Notes as of June 30, 2017March 31, 2018.

NOTE 7 – ASSET RETIREMENT OBLIGATIONS

We are required to record the estimated fair value of the liabilities relating to the future retirement of our long-lived assets. Our oil and natural gas wells are plugged and abandoned when the oil and natural gas reserves in those wells are depleted or the wells are no longer able to produce. The plugging and abandonment liability for a well is recorded in the period in which the obligation is incurred (at the time the well is drilled or acquired). None of our assets are restricted for purposes of settling these AROs. All our AROs relate to the plugging costs associated with our oil and gas wells.

NOTE 8 – NEW ACCOUNTING PRONOUNCEMENTS

Compensation—Stock Compensation. The FASB issued ASU 2017-09, to clarify and reduce both (i) diversity in practice and (ii) cost and complexity when applying its guidance to changes in the terms and conditions of a share-based payment award. The amendments are effective for reporting periods beginning after December 15, 2017. We are in the process of evaluating the impact these amendments will have on our financial statements.

Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment. The FASB issued ASU 2017-04, to simplify the subsequent measurement of goodwill. The amendments eliminateamendment eliminates Step 2 from the goodwill impairment test. The amendmentsamendment will be effective prospectively for reporting periods beginning after December 31,15, 2019, and early adoption is permitted. We doThis amendment will not believe these amendments will have a material impact on our financial statements.

Business Combinations; Clarifying the Definition of a Business. The FASB issued ASU 2017-01, clarifying the definition of a business. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public companies, the amendments are effective for annual periods beginning after December 15, 2017. We are in the process of evaluating the impact these amendments will have on our financial statements.

Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments.  The FASB issued ASU 2016-15, to address diversity in how certain transactions are presented and classified in the statement of cash flows. The amendments will be effective retrospectively for reporting periods beginning after December 31, 2017, and early adoption is permitted. We do not believe these amendments will have a material impact on our financial statements.

Leases. The FASB has issued ASU 2016-02. The amendmentsamendment will require lessees to recognize at the commencement date a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee's right to use a specified asset for the lease term. Lessor accounting is largely unchanged. In January 2018, the FASB issued ASU 2018-01, "Leases - Land Easement practical expedient for Transition to Topic 842", which provides clarifying guidance regarding land easements and adds practical expedients. For public companies, the amendments areamendment is effective for annual periods beginning after

December 15, 2018, and interim periods within those annual periods. Early adoptionThe standard will not apply to leases of mineral rights. We have begun the identification of leases and impact assessment within the scope of the amendments is permitted. We are in the processguidance. Our evaluation of evaluating the impact these amendments will haveof the new guidance on our financial statements in on-going.

Adopted Standards

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The FASB issued ASU 2018-02, an amendment which provides financial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings caused by the Tax Cuts and Jobs Act of 2017. The amendment is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Organizations should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. We adopted this amendment early and it did not have a material effect to our financial statements. We previously used 37.75% to calculate the tax effect on AOCI and now we are using 24.5%. The change is reflected in our Unaudited Condensed Consolidated Statements of Comprehensive Income and in Note 13 - Equity.

Revenue from Contracts with Customers. Effective January 1, 2018, the company adopted ASC 606. The FASB has issued ASU 2014-09. These amendments affect any entity using U.S. GAAP that either enters into contracts with customersnew revenue standard provides a five-step analysis of transactions to transfer goods or services or enters into contracts fordetermine when and how revenue is recognized. The guidance in this update supersedes the transfer of nonfinancial assets unless those contracts are withinrevenue recognition requirements in ASC 605, Revenue Recognition, and most industry-specific guidance throughout the scope of other standards (e.g., insurance contracts or lease contracts). The core principleIndustry Topics of the amendmentsCodification. Under the standard, revenue is that an entity should recognize revenue to depict the transferrecognized when a customer obtains control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitledreceive in exchange for those goods or services. In May 2016,addition, the FASB issuedstandard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The company applied the five step method outlined in the ASU 2016-12, "Narrow-Scope Improvementsto all revenue streams in the scope of ASC 606 and Practical Expedients," which provides clarifying guidanceelected the modified retrospective approach method. Under that approach the cumulative effect on adoption is recognized as an adjustment to opening retained earnings at January 1, 2018. Only our mid-stream segment was affected. This adjustment related to the timing of revenue on certain demand fees. Both our oil and natural gas and contract drilling segments had no retained earnings adjustment. Comparative prior periods have not been adjusted and continue to be reported under ASC 605.

The additional disclosures required by ASC 606 have been included in certain areas and adds some practical expedients. Also in May 2016, the FASB issued ASU 2016-11, "Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting." This amendment rescinds SEC Staff Observer comments that are codified in Topic 605, Revenue Recognition, and Topic 932, Extractive Activities- Oil and Gas, effective on the adoption of Topic 606,Note 2 – Revenue from Contracts with Customers. In April 2016,

Our internal control framework did not materially change, but the FASB issued ASU 2016-10, "Identifying Performance Obligations and Licensing," which amends theexisting internal controls have been modified to consider our new revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. The FASB has issued 2015-14, which defers the effective date to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. We will adopt these amendmentsrecognition policy effective January 1, 2018. We are utilizing a bottom-up approach to analyze the impact ofAs we implement the new standard, on our contracts by reviewing our current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard. We have an implementation team evaluating contracts for the various revenue streams of our business segments to address changes to business processes, systems, and controls. While we have not identified any material differences inadded internal controls to ensure that we adequately evaluate new contracts under the amount and timing of revenue recognition to date, our evaluation is not complete, and we have not reached a conclusion on the overall impacts of adopting Topic 606. Topic 606 provides for adoption either retrospectively to each prior reporting period presented or as a cumulative effect adjustment to retained earnings at the date of adoption. We plan to adopt using the cumulative effect method.five-step model under ASU 2014-09.

Adopted Standards

Income Taxes: Balance Sheet Classification of Deferred Taxes. The FASB has issued ASU 2015-17. This changes how deferred taxes are classified on organizations' balance sheets. Organizations are required to classify all deferred tax assets and liabilities as noncurrent. The amendments apply to all organizations that present a classified balance sheet. For public companies, the amendments were effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The amendments require current deferred tax assets to be combined with noncurrent deferred tax assets. We have adopted this ASU during the first quarter of 2017 on a prospective basis. Previously, we had a net current deferred tax asset which is now netted with our noncurrent deferred tax liability. Prior periods were not retrospectively adjusted.

Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting. The FASB has issued ASU 2016-09. The amendments are intended to improve the accounting for employee share-based payments and affect all organizations that issue share-based payment awards to their employees. Several aspects of the accounting for share-based payment award transactions are simplified, including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the statement of cash flows. For public companies, the amendments were effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The amendments primarily impact classification within the statement of cash flows between financial and operating activities. This did not have a material impact on our financial statements.

The time vested restricted stock awards granted during the first sixthree months of 20172018 and 20162017 are being recognized over a three-year vesting period. During the first two quarters of 2017 and the first quarter of 2016,2018 and 2017, there were two different performance vested restricted stock awards granted to certain executive officers. The first will cliff vest three years from the grant date based on the company's achievement of certain stock performance measures (TSR) at the end of the term and will range from 0% to 200% of the restricted shares granted as performance shares. The second will vest, one-third each year, over a three-year vesting period subject to the company's achievement of cash flow to total assets (CFTA) performance measurement each year and will range from 0% to 200%. Based on a probability assessment of the selected TSR performance criteria at June 30, 2017,March 31, 2018, the participants are estimated to receive 74%27% of the 2018, 93% of the 2017, 145%and 164% of the 2016 and 34% of the 2015 performance based shares. The CFTA performance measurement at June 30, 2017March 31, 2018 was assessed to vest at target or 100%. The total aggregate stock compensation expense and capitalized cost related to oil and natural gas properties for 20172018 awards for the first sixthree months of 20172018 was $3.4$1.1 million.

NOTE 10 – DERIVATIVES

Commodity Derivatives

We have entered intosigned various types of derivative transactions covering some of our projected natural gas and oil production. These transactions are intended to reduce our exposure to market price volatility by setting the price(s) we will receive for that production. Our decisions on the price(s), type, and quantity of our production subject to a derivative contract are based, in part, on our view of current and future market conditions. As of June 30, 2017March 31, 2018, our derivative transactions were comprised of the followingthese hedges:

Swaps. We receive or pay a fixed price for the commodity and pay or receive a floating market price to the counterparty. The fixed-price payment and the floating-price payment are netted, resulting in a net amount due to or from the counterparty.

Basis Swaps. We receive or pay the NYMEX settlement value plus or minus a fixed delivery point price for the commodity and pay or receive the published index price at the specified delivery point. We use basis swaps to hedge the price risk between NYMEX and its physical delivery points.

Collars. A collar contains a fixed floor price (put) and a ceiling price (call). If the market price exceeds the call strike price or falls below the put strike price, we receive the fixed price and pay the market price. If the market price is between the call and the put strike price, no payments are due from either party.


Three-way collars. A three-way collar contains a fixed floor price (long put), fixed subfloor price (short put), and a fixed ceiling price (short call). If the market price exceeds the ceiling strike price, we receive the ceiling strike price and pay the market price. If the market price is between the ceiling and the floor strike price, no payments are due from either party. If the market price is below the floor price but above the subfloor price, we receive the floor strike price and pay the market price. If the market price is below the subfloor price, we receive the market price plus the difference between the floor and subfloor strike prices and pay the market price.

We have documented policies and procedures to monitor and control the use of derivative transactions. We do not engage in derivative transactions for speculative purposes. Any changes in the fair value of our derivative transactions occurring before maturity (i.e., temporary fluctuations in value) are reported in gain (loss) on derivatives in our Unaudited Condensed Consolidated Statements of Operations.Income Statements.

NOTE 11 – FAIR VALUE MEASUREMENTS

The estimated fair value of our available-for-sale securities, reflected on our Unaudited Condensed Consolidated Balance Sheets as Non-current other assets, is based on market quotes. The following is a summary of available-for-sale securities:

  Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value

During the second quarter of 2017, we received available-for-sale securities for early termination fees associated with a long-term drilling contract. We will evaluate the marketable of those equity securities to determine if any decline in fair value below cost is other-than-temporary. If a decline in fair value below cost is determined to be other-than-temporary, an impairment charge will be recorded, and a new cost basis established. We will review several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, (i) the length of time a security is in an unrealized loss position, (ii) the extent to which fair value is less than cost, (iii) the financial condition and near-term prospects of the issuer, and (iv) our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Fair value is defined as the amount that would be received from the sale of an asset or paid for the transfer oftransferring a liability in an orderly transaction between market participants (in either case, an exit price). To estimate an exit price, a three-level hierarchy is used prioritizing the valuation techniques used to measure fair value into three levels with the highest priority given to Level 1 and the lowest priority given to Level 3. The levels are summarized as follows:

Level 1—unadjusted quoted prices in active markets for identical assets and liabilities.

Level 2—significant observable pricing inputs other than quoted prices included within level 1 either directly or indirectly observable as of the reporting date. Essentially, inputs (variables used in the pricing models) that are derived principally from or corroborated by observable market data.

Level 3—generally unobservable inputs which are developed based on the best information available and may include our own internal data.

The inputs available to us determine the valuation technique we use to measure the fair values of our financial instruments.

All our counterparties are subject to master netting arrangements. If a legal right of set-off exists, we net the value of the derivative transactions we have with the same counterparty. We are not required to post cash collateral with our counterparties and no collateral has been posted as of June 30, 2017.March 31, 2018.

We used the following methods and assumptions to estimate the fair values of the assets and liabilities in the table above. There were no transfers between Level 2 and Level 3 financial assets (liabilities).

Level 1 Fair Value Measurements

Equity Securities. We measure the fair values of our available for sale securities based on market quotes.

Level 2 Fair Value Measurements

Commodity Derivatives. We measure the fair values of our crude oil and natural gas swaps using estimated internal discounted cash flow calculations based on the NYMEX futures index.

Level 3 Fair Value Measurements

Commodity Derivatives. The fair values of our natural gas and crude oil collars and three-way collars are estimated using internal discounted cash flow calculations based on forward price curves, quotes obtained from brokers for contracts with similar terms, or quotes obtained from counterparties to the agreements.

(1)The commodity contracts detailed in this category include non-exchange-traded crude oil and natural gas collars and three-way collars that are valued based on NYMEX. The forward pricing range represents the low and high price expected to be paid or received within the settlement period.

Our valuation at June 30, 2017March 31, 2018 reflected that the risk of non-performance by our counterparties was immaterial.

Fair Value of Other Financial Instruments

The followingThis disclosure of the estimated fair value of financial instruments is made in accordance withunder accounting guidance for financial instruments. We have determined the estimated fair values by using available market information and valuation methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. The use ofUsing different market assumptions or valuation methodologies may have a material effect on the estimated fair value amounts.


At June 30, 2017March 31, 2018, the carrying values on the Unaudited Condensed Consolidated Balance Sheets for cash and cash equivalents (classified as Level 1), accounts receivable, accounts payable, other current assets, and current liabilities approximate their fair value because of their short-term nature.

Based on the borrowing rates currently available to us for credit agreement debt with similar terms and maturities and considering the risk of our non-performance, long-term debt under our credit agreement approximates its fair value and at June 30, 2017March 31, 2018 and December 31, 20162017 was $164.9$147.7 million and $160.8$178.0 million, respectively. This debt would be classified as Level 2.

The carrying amounts of long-term debt associated with the Notes, net of unamortized discount and debt issuance costs, associated with the Notes reported in the Unaudited Condensed Consolidated Balance Sheets as of June 30, 2017March 31, 2018 and December 31, 20162017 were $641.2$642.8 million and $640.1642.3 million, respectively. We estimate the fair value of the Notes using quoted marked prices at June 30, 2017March 31, 2018 and December 31, 20162017 was $627.9632.9 million and $649.9649.7 million, respectively. The Notes would be classified as Level 2.


Fair Value of Non-Financial Instruments

The initial measurement of AROs at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant, and equipment. Significant Level 3 inputs used in the calculation of AROs include plugging costs and remaining reserve lives. A reconciliation of the Company’scompany’s AROs is presented in Note 7 – Asset Retirement Obligations.

NOTE 12 – COMMITMENTS AND CONTINGENCIES

We lease office space or yards in Edmond and Oklahoma City, Oklahoma; Houston, Texas; Englewood, Colorado; Pinedale, Wyoming; and Canonsburg, Pennsylvania under the terms of operating leases expiring through December 2021. We also have several compressor rentals, equipment leases, and lease space on short-term commitments to stack excess drilling rig equipment and production inventory. Future minimum rental payments under the terms of the leases are approximately $3.5$2.7 million, $1.1$0.9 million, $0.4 million, $0.3 million, and less than $0.1 million in twelve monthtwelve-month periods beginning JulyApril 1, 20172018 (and through the end of 2021), respectively. Total rent expense incurred was $4.2$2.3 million and $6.2$2.1 million for the first sixthree months of 20172018 and 2016,2017, respectively.

In 2014, our mid-stream segment entered intosigned capital lease agreements for 20 compressors with initial terms of seven years. Estimated annual capital lease payments under the terms during the fivefour successive twelve monthtwelve-month periods beginning JulyApril 1, 20172018 (and through the end of 2021) are $6.2 million, $6.2 million, $6.2 million, $6.7$7.8 million, and $0.2$0.6 million. Total maintenance and interest remaining related to these leases are $6.8$5.4 million and $1.5$1.0 million, respectively at June 30, 2017.March 31, 2018. Annual payments, net of maintenance and interest, average $4.1$4.2 million annually through 2021. At the end of the term, our mid-stream segment has the option to purchase the assets at 10% of their then fair market value.

The employee oil and gas limited partnerships require, on the election of a limited partner, that we repurchase the limited partner’s interest at amounts to be determined by appraisal. In any one year, these repurchases are limited to 20% of the units outstanding. We had no repurchases in the first six monthsquarter of 20172018 or 2016.2017.

We manage our exposure to environmental liabilities on properties to be acquired by identifying existing problems and assessing the potential liability. We also conduct periodic reviews, on a company-wide basis, to identify changes in our environmental risk profile. These reviews evaluate whether there is a probable liability, its amount, and the likelihood that the liability will be incurred. Any potential liability is determined by considering, among other matters, incremental direct costs of any likely remediation and the proportionate cost of employees expected to devote significant time directly to any possible remediation effort. As it relates to evaluations of purchased properties, depending on the extent of an identified environmental problem, we may exclude a property from the acquisition, require the seller to remediate the property to our satisfaction, or agree to assume liability for the remediation of the property.

We have not historically experienced any environmental liability while being a contract driller since the greatest portion of risk is borne by the operator. Any liabilities we have incurred have been small and have been resolved while the drilling rig is on the location and the cost has been included in the direct cost of drilling the well.

For the next twelve months, we have committed to purchase approximately $3.9$3.4 million of new drilling rig components.


NOTE 13 – EQUITY

At-the-Market (ATM) Common Stock Program 

On April 4, 2017, we entered intosigned a Distribution Agreement (the Agreement) with a sales agent, under which we may offer and sell, from time to time, through the sales agent shares of our common stock, par value $.20 per share (the Shares), up to an aggregate offering price of $100.0 million. We intend to use the net proceeds from these sales to fund (or offset costs of) acquisitions, future capital expenditures, repay amounts outstanding under our revolving credit facility, and general corporate purposes.
 
Under the Agreement, the sales agent may sell the Shares by methods deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, including sales made directly on the NYSE, on any other existing trading market for the Shares or to or through a market maker. In addition, under the Agreement, the sales agent may sell the Shares by any other method permitted by law, including in privately negotiated transactions. Subject to the terms and conditions of the Agreement, the sales agent will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal law, rules and regulations and the rules of the NYSE, to sell the Shares from

time to time, based on our instructions (including any price, time or size limits or other customary parameters or conditions that we may impose).
 
We aredo not obligatedhave to make any sales of the Shares under the Agreement. The offering of Shares under the Agreement will terminate on the earlier of (1) the sale of all of the Shares subject to the Agreement or (2) the termination of the Agreement by the sales agent or us. We will pay the sales agent a commission of 2.0% of the gross sales price per share sold and have agreed to provide the sales agent with customary indemnification and contribution rights.
 
As of June 30, 2017,March 31, 2018, we have sold 787,547 shares of our common stock resulting in net proceeds of approximately $18.6 million. No shares were sold in the first quarter of 2018. On May 2, 2018, we terminated this Agreement, the details are discussed in Note 15 — Subsequent Events.

NOTE 14 – INDUSTRY SEGMENT INFORMATION

We have three main business segments offering different products and services within the energy industry:
 
Oil and natural gas,
Contract drilling, and
Mid-stream

Our oil and natural gas segment is engaged in the acquisition, development, and production of oil, NGLs, and natural gas properties. The contract drilling segment is engaged in the land contract drilling of oil and natural gas wells and the mid-stream segment is engaged in the buying, selling, gathering, processing, and treating of natural gas and NGLs.

We evaluate each segment’s performance based on its operating income, which is defined as operating revenues less operating expenses and depreciation, depletion, amortization, and impairment. We have no oil and natural gas production outside the United States.


The following tables provide certain information about the operations of each of our segments:

_______________________The Fourth Amendment was signed in connection with our sale of 50% of our ownership interest in our midstream segment, Superior Pipeline Company, L.L.C. One of the conditions of that sale was the release of Superior from the terms of the credit agreement. Since the Fourth Amendment needed to be signed before the closing of the Superior sale it was designed to account for the possibility the Superior sale might not close as anticipated. The Fourth Amendment provides, among other things, for a reduction of the maximum credit amount from $875.0 million to $475.0 million, and an increase in the borrowing base from $475.0 million to $525.0 million; provide that part of the proceeds from the sale be used to pay down the existing outstanding principal balance under the credit agreement. Once that payment was made on April 3, 2018-(i) the total commitment amount was reduced from $475.0 million to $425.0 million; (ii) the maximum credit amount was reduced from $475.0 million to $425.0 million and set as the amount that would otherwise be subject to redetermination in April; (iii) the borrowing base was reduced from $525.0 million to $425.0 million; and (iv) Superior and its subsidiaries (Superior), were fully released as a borrower and co-obligor under the credit agreement. The Superior sale closed on April 3, 2018 and the paydown under the credit agreement was made that same day.
(1)Operating income (loss) is total operating revenues less operating expenses, depreciation, depletion, amortization, and impairment and does not include general corporate expenses, gain (loss) on disposition of assets, loss on derivatives, interest expense, other income (loss), or income taxes.

The 50% interest in Superior we sold was acquired by SP Investor Holdings, LLC, a holding company jointly owned by OPTrust and funds managed and/or advised by Partners Group, a global private markets investment manager (Purchaser), for

cash consideration of $300.0 million. The sale closed under the purchase and sale agreement (the Purchase Agreement) dated March 28, 2018 and closed on April 3, 2018. Part of the proceeds from the sale were used to pay down our bank debt and the remainder will be used to accelerate the drilling program of our upstream subsidiary, Unit Petroleum Company, make additional capital investments in the jointly owned Superior, and for general working capital purposes. In connection with the sale of the interest in Superior, the company and its board of directors took the necessary actions under the Indenture governing the company's outstanding senior subordinated notes to secure the ability to close the sale and to have Superior released from the Indenture.

Superior will be governed and managed by the Amended and Restated Limited Liability Company Agreement and Master Services and Operating Agreement, respectively, both of which are included as exhibits to the Purchase and Sale Agreement filed with this report.

On May 2, 2018, we terminated the Distribution Agreement dated April 4, 2017, as amended (the Distribution Agreement), between the company and Raymond James & Associates, Inc. (the Sales Agent). The Distribution Agreement was terminable at will on written notification by the company with no penalty. Under the Distribution Agreement, the company was entitled to issue and sell, from time to time, through or to the Sales Agent shares of its common stock, having an aggregate offering price of up to $100.0 million in an “at-the-market” offering program. As of the date of termination, the company sold 787,547 shares of its Common Stock under the Distribution Agreement. As a result of the termination, there will be no more sales of the our common stock under the Distribution Agreement.





Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis (MD&A) provides you with an understanding of our operating results and financial condition by focusing on changes in certain key measures from year to year or period to period. MD&A is organized into the followingthese sections: 

General;
Business Outlook;
Executive Summary;
Financial Condition and Liquidity;
New Accounting Pronouncements; and
Results of Operations.

Please read the information in our most recent Annual Report on Form 10-K with your review of the information below as well asand our unaudited condensed consolidated financial statements and related notes.

Unless otherwise indicated or required by the content, when used in this report the terms “company,” “Unit,” “us,” “our,” “we,” and “its” refer to Unit Corporation or, as appropriate, one or more of its subsidiaries.

General

We operate, manage, and analyze the results of our operations through our three principal business segments: 

Oil and Natural Gas – carried out by our subsidiary Unit Petroleum Company. This segment explores, develops, acquires, and produces oil and natural gas properties for our own account.
Contract Drilling – carried out by our subsidiary Unit Drilling Company. This segment contracts to drill onshore oil and natural gas wells for others and for our oil and natural gas segment.
Mid-Stream – carried out by our subsidiary Superior Pipeline Company, L.L.C. and its subsidiaries. This segment buys, sells, gathers, processes, and treats natural gas for third parties and for our oil and natural gas segment.

Business Outlook

As discussed in other parts of this report, our success depends, to a large degree, on the prices we receive for our oil and natural gas production, the demand for oil, natural gas, and NGLs, as well as,and the demand for our drilling rigs which in turn, influences the amounts we can charge for those drilling rigs. While our operations are located within the United States, events outside the United States affect us and our industry.

DeterioratingFluctuating commodity prices worldwide during the past several years brought about significant and adverse changes to our industry and us. As a result we reduced or stopped, for a period of time, our oil and natural gas segment's drilling activity. Industry wide reductions in drilling activity and spending for extended periods also tends to reducereduces the rates for and the number of our drilling rigs that we can work. In addition, sustained lower commodity prices impact the liquidity condition of some of our industry partners and customers, which in turn, could limit their ability to meet their financial obligations to us.

During 2016,Recently, commodity prices began to improve. Inhave improved. During the fourthfirst quarter of 2016,2018, our oil and natural gas segment began using twoused four of our drilling rigs and has continued using themused three to four during the first six months of 2017. Our contract drilling segment completed the construction and contracted the ninth andour tenth BOSS drilling rigsrig in the fourth quarter of 2016 and the second quarter of 2017, respectively.and is constructing the eleventh. Our drilling rig segment's rig utilization increased from 16an average of 25.5 drilling rigs working asduring the first quarter of June 30, 2016,2017 to 3331.7 average drilling rigs working as of June 30, 2017. The extent and duration of this improvement remains uncertain.


The reduction in oil, NGLs, and natural gas prices had a number of consequences for us (although, as noted, we are starting to see some improvements). Below are some of those consequences:

We incurred non-cash ceiling test write-downs induring the first nine monthsquarter of 2016 of $161.6 million ($100.6 million net of tax). We did not have a write-down2018. Rig utilization fluctuated over the past year due to commodity prices changing and budget constraints on operators in the fourth quarter of 2016 or2017. We expect this same trend to continue in 2018.


Other recent improvements:

We have not incurred a non-cash ceiling test write-down since 2016. We had no write-down in the first two quartersquarter of 2018 nor the first quarter of 2017. It is hard to predict with any reasonable certainty the need for or amount of any future impairments given the many factors that go into the ceiling test calculation including, but not limited to, future pricing, operating costs, drilling and completion costs, upward or downward oil and gas reserve revisions, oil and gas reserve additions, and tax attributes. Subject to these inherent uncertainties, if we hold these same factors constant as they existed at June 30, 2017March 31, 2018, and only adjust the 12-month average price to an estimated thirdsecond quarter ending average (holding July 2017April 2018 prices constant for the remaining two months of the thirdsecond quarter of 2017)2018), our forward looking expectation is that we will not recognize an impairment in the thirdsecond quarter of 2017.2018. But commodity prices (and other factors) remain volatile and they could negatively impactaffect the 12-month average price resulting in the potential for an impairment in the future.a future impairment.

We reducedincreased the number of gross wells our oil and natural gas segment drilledplan to drill in 2016 by approximately 64% from the number drilled in 2015 due2018 to our reduced cash flow. For75-85 wells (depending on future commodity prices). In 2017, we plan to increaseincreased the number of gross wells drilled by approximately 67-90% (depending on future commodity prices)to 70 from the number of wells drilled21 in 2016.
The decline in drilling by our customers reduced the average utilization of our drilling rig fleet. At December 31, 2015, we had 26 drilling rigs operating. In 2016 utilization continued downward bottoming out in May 2016 at 13 operating drilling rigs. After May commodity prices began improving for the remainder of the year and we exited 2016 with 21 active rigs. As of June 30, 2017, we had 33 drilling rigs operating (an improvement of 57% over the end of the year). Operators have been increasing drilling, but the extent of further increases remain uncertain. During the second quarter of 2017, we completed the construction of our tenth BOSS drilling rig and all of our BOSS drilling rigs are under contract.
Duedue to low NGLs prices, we continue to operate most of our mid-stream processing facilities in ethane rejection mode which reduces the amount of liquids sold. As long as NGLs prices remain depressed, we expect to continue operating in ethane rejection mode.
Also, as noted elsewhere, beginning on April 4, 2017, we began an at-the-market offering for the sale of shares of our common stock. The offering allows us to sell shares, from time to time, up to an aggregate of $100 million in gross proceeds. As of June 30, 2017, we sold 787,547 shares for $18.6 million, net of offering costs of $0.4 million. Approximately $81.0 million remain available for sale under the program. Net proceeds from the offering will be used to fund (or offset costs of) acquisitions, future capital expenditures, repay amounts outstanding under our revolving credit facility, and general corporate purposes.increased cash flow.

On April 3, 2017, we closed2018, the company completed the sale of 50% of the ownership interests in Superior to SP Investor Holdings, LLC, a holding company jointly owned by OPTrust and funds managed and/or advised by Partners Group, a global private markets investment manager, for cash consideration of $300 million. Part of the proceeds from the sale were used to pay down our bank debt and the balance will be used to accelerate the drilling program of our upstream subsidiary, Unit Petroleum Company, make additional capital investments in the jointly owned Superior, and for general working capital purposes.

The unaudited pro forma consolidated income statement for the quarter ended March 31, 2018, if presented, would contain an acquisitionadjustment to increase net income for $2.2 million resulting from the reduction in interest due to the payment of certain oilbank debt and natural gas assetsthe benefit from lower effective tax rate due to non-controlling interest. There is also an unrelated third party.

Executive Summary

Oil and Natural Gas

SecondFirst quarter2017 2018 production from our oil and natural gas segment was 3,852,0004,181,000 barrels of oil equivalent (Boe), a decrease of 3% from the fourth quarter of 2017 and an increase of 2%11% over the first quarter of 2017, and a respectively. The decrease of 12% from the secondfourth quarter of 2016, respectively.2017 was due to delays in completing newer wells drilled. The increase over the first quarter of 2017 was primarily from acquired wells and new wells drilled in the first six months ofduring 2017. The decrease from the second quarter of 2016 was primarily due to the continued production decline of existing wells and reduced drilling activity between the periods. Second quarter 2017 production was also negatively affected by approximately 94,000 Boe due to third party gas processing outages and the delay of several fracture stimulation jobs from early May until early June.

For the sixthree months ended June 30, 2017,March 31, 2018, we completed drilling 1915 gross wells (8.21(5.40 net wells). For all of 2017,2018, we plan to participateanticipate participating in the drilling of approximately 3575 to 4085 gross wells.Excluding acquisitions and ARO liability, our estimated 20172018 capital expenditures for this segment are approximately $197.0$272.0 million. Our current 20172018 production guidance is approximately 16.017.1 to 16.517.4 MMBoe, a decreasean increase of 4% to 7%7-9% from 2016,2017, although actual results continue to be subject to many factors.


Contract Drilling

The average number of drilling rigs we operated in the secondfirst quarter of 2018 was 31.7 compared to 31.2 and 25.5 in the fourth quarter of 2017 was 28.8 compared to 25.5 and 13.5 in the first quarter of 2017, and the second quarter of 2016, respectively. As of June 30, 2017, 33March 31, 2018, 32 of our drilling rigs were operating.

Revenue for the secondfirst quarter of 2018 decreased 1% from the fourth quarter of 2017 and increased 6% and 62%24% over the first quarter of 2017, andrespectively. The decrease from the secondfourth quarter of 2016, respectively. The increases were2017 was primarily due to a decrease in mobilization and other revenues partially offset by an increase in drilling rigs operating partially offset by lower dayrates between the second quarter of 2017 and the second quarter of 2016.

Dayrates for the second quarter of 2017 averaged $15,962, a 1% increase over the first quarter of 2017 and a 14% decrease from the second quarter of 2016.dayrates. The increase over the first quarter of 2017 was primarily due to increased demand. The decrease from the second quarter of 2016 was primarily due to downward pressure on dayrates due to lower demand.utilization and an increase in dayrates.

Operating costsDayrates for the second quarter of 2017 decreased 7% from the first quarter of 2018 averaged $17,038, a 2% increase over the fourth quarter of 2017 and increased 41%an 8% increase over the secondfirst quarter of 2016.2017. The decrease fromincrease over the firstfourth quarter of 2017 was primarily due to less new rig activation costs.a labor increase in the first quarter of 2018 passed through to contracted rigs. The

increase over the secondfirst quarter of 20162017 was due to two labor increases passed through to contracted rigs and improving market dayrates.

Operating costs for the first quarter of 2018 increased 1% over the fourth quarter of 2017 and increased 8% over the first quarter of 2017. The increases were due primarily to more drilling rigs operating partially offset by decreased per day cost.

Almost all of our working drilling rigs were drilling horizontal or directional wells for oil and NGLs. The improved commodity pricing for oil and natural gas that began during the second half of 2016 has increased demand for drilling rigs. Our drilling rig count bottomed out at 13 drilling rigs operating during the second quarter of 2016, but increased to 21 drilling rigs operating at the end of 2016. Our drilling rig count continued to increase during the first half of 2017 ending at 33 operating drilling rigs. The future demand for and the availability of drilling rigs to meet that demand will affect our future dayrates.operating.

We have 15six term drilling contracts with original terms ranging from six months to two years. Seven areOne is up for renewal in the second quarter of 2018, two in the third quarter of 2017, six2018, two in the fourth quarter of 2017, one is up for renewal in 2018, and one in 2019. Term contracts may contain a fixed rate during the contract or provide for rate adjustments within a specific range from the existing rate. Some operators with signed term contracts opted to release the drilling rig and pay an early termination penalty for the remaining term of the contract. During the first six months of 2017, we recorded $0.8 million of early termination fees compared to $3.0 million in the first six months of 2016.

All ten of our existing BOSS drilling rigs are under contract. Construction was completed on our tenth BOSS drilling rig and the rig was placed into service late in the second quarter. We also have contracted and placed into service three of our stacked SCR drilling rigs in our Mid-Continent division during the second quarter. One SCR drilling rig was upgraded, one was relocated from our Rocky Mountain division, and the third SCR rig required no modifications. We have two additional stacked SCR drilling rigs returning to service in the third quarter. Both in our Mid-Continent division. One is being relocated from our Rocky Mountain division. Our estimated 20172018 capital expenditures for this segment are approximately $28.0$47.0 million.

Competition to keep qualified labor continues to be an issue we face in this segment.segment and in response, we implemented pay rate increases in certain areas in the first quarter of 2018. We do not believe this shortage of qualified labor will keep us from working additional drilling rigs, but it could cause some delays in the time to crew new drilling rigs. Beginning in third quarter 2017, we increased compensation for certain drilling rig personnel.

Because certain of the contracts used by our mid-stream segment for NGLs transactions are commodity-based contracts–under which we receive a share of the proceeds from the sale of the NGLs–our revenues from those commodity-based contracts fluctuate based on the price of NGLs.

In the Appalachian region, our Pittsburgh Mills gathering system, in Allegheny and Butler counties, continues to produce consistent financial results. Our average gathered volume for the second quarter of 2017 is approximately 133 MMcf per day. We connected the new Allen well pad in May and it included five new wells. And we are constructing a pipeline to connect the Miller well pad, which will be the next pad connected to our system. The Miller pad will include seven new wells and we anticipate it will be ready to flow in the third quarter of 2018. Also, we anticipate several in-fill wells to be drilled and connected to our system in the first half of 2018.

At our Segno gathering facility in Southeast Texas, gathered volume for the secondfirst quarter of 20172018 averaged approximately 79.284.9 MMcf per day. At this facility, we have increased our gathering and dehydration capacity will allow us gather up to approximately 120 MMcf per day. We have connected one new well to this system in 2017.the first quarter of 2018 and the producer in this area is actively reworking and recompleting wells that are connected to our system which will continue to increase gathered volumes.

In the Appalachian region at our Pittsburgh Mills gathering system, our average gathered volume for the first quarter of 2018 is approximately 106.5 MMcf per day. We are currently constructing a new pipeline to connect the next well pad to our system. This pad will include seven new wells and we anticipate construction to be completed in the third quarter. Production from this new pad is expected to begin in the fourth quarter of 2018. Additionally, we are preparing to receive production from several infill wells that are currently being drilled on existing pads. These infill wells are expected to begin flow in the second quarter of this year.

Our estimated 20172018 capital expenditures for this segment are approximately $16.0$32.0 million.

Financial Condition and Liquidity

Summary

Our financial condition and liquidity depends on the cash flow from our operations and borrowings under our credit agreement. Our cash flow is based primarily on:
 
the amount of natural gas, oil, and NGLs we produce;
the prices we receive for our natural gas, oil, and NGLs production;
the demand for and the dayrates we receive for our drilling rigs; and
the fees and margins we obtain from our natural gas gathering and processing contracts.

We believe we will have enough cash flow and liquidity to meet our obligations and remain in compliance with our debt covenants for the next twelve months. Our ability to meet our debt covenants (under our credit agreement and our 2011 Indenture) and our capacity to incur additional indebtedness will depend on our future performance, which will be affected by financial, business, economic, regulatory, and other factors. For example, if we experience lower oil, natural gas, and NGLs prices since the last borrowing base determination under our credit agreement, it could cause a reduction ofreduce the borrowing base and therefore reduce or limit our ability to incur indebtedness. We monitor our liquidity and capital resources, endeavor to anticipate potential covenant compliance issues, and work, where possible, with our lenders to address those issues ahead of time.

Cash Flows from Operating Activities

Our operating cash flow is primarily influenced by the prices we receive for our oil, NGLs, and natural gas production, the quantity of oil, NGLs, and natural gas we produce, settlements of derivative contracts, and third-party demand for our drilling rigs and mid-stream services and the rates we obtain for those services. Our cash flows from operating activities are also impactedaffected by changes in working capital.

Net cash provided by operating activities in the first sixthree months of 2017 decreased2018 increased by $15.7$17.9 million as compared to the first sixthree months of 2016.2017. The decrease was the result ofincrease resulted from changes in operating assets and liabilities related to the timing of cash receipts and disbursements partially offsetand by higher profit marginsthe change in all three segments.the value of outstanding derivatives.

Cash Flows from Investing Activities

We dedicate and expect to continue to dedicate a substantial portion of our capital budget to the exploration for and production of oil, NGLs, and natural gas. These expenditures are necessary to off-set the inherent production declines typically experienced in oil and gas wells.

Cash flows used in investing activities increased by $65.4$39.1 million for the first sixthree months of 20172018 compared to the first sixthree months of 2016.2017. The change was due primarily to an increase in capital expenditures due to an oil and gas property acquisition,increased drilling activity offset by the restarting of our contract drilling program in 2017, the construction of two new BOSS drilling rigs, and a decreaseincrease in the proceeds received from the disposition of assets. See additional information on capital expenditures below under Capital Requirements.

Working Capital

Typically, our working capital balance fluctuates, in part, because of the timing of our trade accounts receivable and accounts payable and the fluctuation in current assets and liabilities associated with the mark to market value of our derivative activity. We had negative working capital of $51.4$102.7 million and $57.5$41.3 million as of June 30,March 31, 2018 and 2017, and 2016, respectively. ThisThe increase in negative working capital is primarily from an increase in accounts receivable due to higher revenues,increased accounts payable due to increased activity in our drilling program and increased drilling rig utilization and the change in the value of outstanding derivatives the reclassification of current deferred tax asset to long-term asset per ASU 2015-17, and decreased accrued liabilities partially offset by increased accounts payable due toreceivable from increased drilling activity and more rigs operating.revenues. Our credit agreement is used primarily for working capital and capital expenditures. At June 30, 2017,March 31, 2018, we had borrowed $164.9$147.7 million of the $475.0 million available under our credit agreement. The effect of our derivative contracts increaseddecreased working capital by $2.9$11.6 million as of June 30, 2017March 31, 2018 and decreased working capital by $9.6$5.6 million as of June 30, 2016.March 31, 2017.

(1)    In the first quarter of 2018, our mid-stream segment transferred two natural gas gathering systems to our oil and natural gas segment.

Oil and Natural Gas Operations

Any significant change in oil, NGLs, or natural gas prices has a material effect on our revenues, cash flow, and the value of our oil, NGLs, and natural gas reserves. Generally, prices and demand for domestic natural gas are influenced by weather conditions, supply imbalances, and by worldwide oil price levels. Global oil market developments primarily influence domestic oil prices. These factors are beyond our control and we cannot predict nor measure their future influence on the prices we will receive.

Based on our first sixthree months of 20172018 production, a $0.10 per Mcf change in what we are paid for our natural gas production, without the effect of derivatives, would cause a corresponding $392,000$436,000 per month ($4.75.2 million annualized) change in our pre-tax operating cash flow. The average price we received for our natural gas production, including the effect of derivatives, during the first sixthree months of 20172018 was $2.57$2.62 compared to $1.83$2.68 for the first sixthree months of 2016.2017. Based on our first sixthree months of 20172018 production, a $1.00 per barrel change in our oil price, without the effect of derivatives, would have a $219,000$237,000 per month ($2.62.8 million annualized) change in our pre-tax operating cash flow and a $1.00 per barrel change in our

NGLs prices, without the effect of derivatives, would have a $362,000$388,000 per month ($4.34.7 million annualized) change in our pre-tax operating cash flow. In the first sixthree months of 2017,2018, our average oil price per barrel received, including the effect of derivatives, was $47.77$55.10 compared with an average oil price, including the effect of derivatives, of $36.88$48.68 in the first sixthree months of 20162017 and our first sixthree months of 20172018 average NGLs price per barrel received was $16.34$21.08 compared with an average NGLs price per barrel of $8.90$17.81 in the first sixthree months of 2016.2017.

Because commodity prices affect the value of our oil, NGLs, and natural gas reserves, declines in those prices can cause a decline in the carrying value of our oil and natural gas properties. At June 30, 2017,March 31, 2018, the 12-month average unescalated prices were $48.95$53.49 per barrel of oil, $24.97$33.18 per barrel of NGLs, and $3.01$3.00 per Mcf of natural gas, asand then are adjusted for price differentials. We did not have to take a write down in the first sixthree months of 2017.2018.

It is hard to predict with any reasonable certainty the need for or amount of any future impairments given the many factors that go into the ceiling test calculation including, but not limited to, future pricing, operating costs, drilling and completion costs, upward or downward oil and gas reserve revisions, oil and gas reserve additions, and tax attributes. Subject to

these inherent uncertainties, if we hold these same factors constant as they existed at June 30, 2017,March 31, 2018, and only adjust the 12-month average price to an estimated thirdfourth quarter ending average (holding July 2017April 2018 prices constant for the remaining two months of the thirdsecond quarter of 2017)2018), our forward looking expectation is that we will not recognize an impairment in the thirdsecond quarter of 2017.2018. But commodity prices (and other factors) remain volatile and they could negatively affect the 12-month average price resulting in the potential for an impairment in the future.a future impairment.

Our natural gas production is sold to intrastate and interstate pipelines and to independent marketing firms and gatherers under contracts with terms ranging from one month to five years. Our oil production is sold to independent marketing firms generally inunder six month increments.contracts.

Contract Drilling Operations

Many factors influence the number of drilling rigs we are working and the costs and revenues associated with that work. These factors include the demand for drilling rigs in our areas of operation, competition from other drilling contractors, the prevailing prices for oil, NGLs, and natural gas, availability and cost of labor to run our drilling rigs, and our ability to supply the equipment needed.

Most of our working drilling rigs were drilling horizontal or directional wells for oil and NGLs. The improvedcontinuous fluctuations in commodity pricingprices for oil and natural gas that began duringchanges the second half of 2016 has increased demand for drilling rigs. These factors ultimately affect the demand and mix of the type of drilling rigs used by our customers. The future demand for and the availability of drilling rigs to meet that demand will affect our future dayrates. For the first sixthree months of 20172018, our average dayrate was $15,905$17,038 per day compared to $18,468$15,835 per day for the first sixthree months of 2016.2017. The average number of our drilling rigs used in the first sixthree months of 20172018 was 27.231.7 drilling rigs compared with 17.125.5 drilling rigs in the first sixthree months of 2016.2017. Based on the average utilization of our drilling rigs during the first sixthree months of 20172018, a $100 per day change in dayrates has a $2,720$3,170 per day ($1.01.2 million annualized) change in our pre-tax operating cash flow.

Our contract drilling segment provides drilling services for our exploration and production segment. Some of the drilling services we perform on our properties are, depending on the timing of those services, deemed to be associated with acquiring an ownership interest in the property. In those cases, revenues and expenses for those services are eliminated in our statement of operations,income statements, with any profit recognized as a reduction in our investment in our oil and natural gas properties. The contracts for these services are issued under the same conditions and rates as the contracts entered into with unrelated third parties. We eliminated revenue of $5.6$4.7 million for the first sixthree months of 20172018 from our contract drilling segment and eliminated the associated operating expense of $5.2$4.3 million yielding $0.4 million as a reduction to the carrying value of our oil and natural gas properties. We eliminated no revenue in our contract drilling segment for the first sixthree months of 2016.2017.

Mid-Stream Operations

Our mid-stream segment is engaged primarily in the buying, selling, gathering, processing, and treating of natural gas. It operates three natural gas treatment plants, 13 processing plants, 2522 gathering systems, and approximately 1,4701,450 miles of pipeline. It operates in Oklahoma, Texas, Kansas, Pennsylvania, and West Virginia. Besides serving third parties, this segment also enhances our ability to gather and market our own natural gas and NGLs and serving as a mechanism through which we can construct or acquire existing natural gas gathering and processing facilities. During the first sixthree months of 20172018 and 20162017, our mid-stream operations purchased $27.3$16.9 million and $16.4$13.9 million, respectively, of our natural gas production and NGLs, and provided gathering and transportation services of $3.2$1.7 million and $5.1$1.6 million, respectively. Intercompany revenue from

services and purchases of production between this business segment and our oil and natural gas segment has been eliminated in our unaudited condensed consolidated financial statements.

This segment gathered an average of 386,893372,862 Mcf per day in the first sixthree months of 20172018 compared to 411,671390,384 Mcf per day in the first sixthree months of 2016.2017. It processed an average of 130,804151,039 Mcf per day in the first sixthree months of 20172018 compared to 164,333126,559 Mcf per day in the first sixthree months of 2016.2017. The amount of NGLs sold was 511,969577,560 gallons per day in the first sixthree months of 20172018 compared to 525,824497,862 gallons per day in the first sixthree months of 2016.2017. Gas gathered volumes per day in the first sixthree months of 20172018 decreased 6%4% compared to the first sixthree months of 20162017 primarily due to declines in existingdeclining volumes fewer new wells connected, and losing an offload volume aton our Hemphill facility in mid-2016.Appalachian systems. Gas processed volumes for the first sixthree months of 2018 increased 19% over the first three months of 2017 decreased 20% from the first six months of 2016 due to declines in existing volumes, fewer newadditional wells connected to our processing systems and losing anhigher offload volume at our Hemphill facility in mid-2016.volumes. NGLs sold decreased 3% fromincreased 16% over the comparative period due to lesshigher volume available to process at our plants.


At-the-Market (ATM) Common Stock Program 

On May 2, 2018, we terminated the Distribution Agreement dated April 4, 2017, we entered into aas amended (the Distribution Agreement), between the company and Raymond James & Associates, Inc. (the Sales Agent). The Distribution Agreement (the Agreement)was terminable at will on written notification by the company with a sales agent, under which we may offerno penalty. Under the Distribution Agreement, the company was entitled to issue and sell, from time to time, through or to the sales agentSales Agent shares of ourits common stock, par value $0.20 per share (the Shares), up tohaving an aggregate offering price of up to $100.0 million. We intend to use the net proceeds from these sales to fund (or offset costs of) acquisitions, future capital expenditures, repay amounts outstanding under our revolving credit facility, and general corporate purposes.
Under the Agreement, the sales agent may sell the Shares by methods deemed to bemillion in an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, including sales made directly on the NYSE, on any other existing trading market for the Shares or to or through a market maker. In addition, under the Agreement, the sales agent may sell the Shares by any other method permitted by law, including in privately negotiated transactions. Subject to the termsprogram. As of the Agreement,date of termination, the sales agent will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal law, rules and regulations and the rules of the NYSE, to sell the Shares from time to time, based on our instructions (including any price, time or size limits or other customary parameters or conditions we may impose).
We do not have to make any sales of the Shares under the Agreement. The offering of Shares under the Agreement will terminate on the earlier of (1) the sale of all of the Shares subject to the Agreement or (2) the termination of the Agreement by the sales agent or us. We will pay the sales agent a commission of 2.0% of the gross sales price per share sold and have agreed to provide the sales agent with customary indemnification and contribution rights.
As of July 21, 2017, wecompany sold 787,547 shares of its Common Stock under the Distribution Agreement. As a result of the termination, there will be no more sales of the our common stock resulting in net proceeds of approximately $18.6 million.under the Distribution Agreement.

Our Credit Agreement and Senior Subordinated Notes

Credit Agreement. OurOn April 2, 2018, we amended our Senior Credit Agreement (credit agreement) is scheduled to mature on April 10, 2020. Under the credit agreement, the amount we can borrow is the lesser of the amount we elect as the commitment amount or the value of the borrowing base as determined by the lenders, but in either event not to exceed $875.0 million. Our elected commitment amount is $475.0 million. Our borrowing base is $475.0 million.the maximum credit agreement. We are charged a commitment fee of 0.50% on the amount available but not borrowed. That fee varies based on the amount borrowed as a percentage of the total borrowing base. We paidPrevious amendment fees of $1.0 million in origination, agency, syndication, and other related fees. Wefees are amortizing these feesbeing amortized over the life of the credit agreement. No new fees were incurred for the Fourth Amendment. Under the credit agreement, we have pledged the following collateral: (a) 85% of the proved developed producing (discounted as present worth at 8%) total value of our oil and gas properties and (b) 100% of our ownership interest in our midstreammid-stream affiliate, Superior Pipeline Company, L.L.C.

The Fourth Amendment was signed in connection with our sale of 50% of our ownership interest in our midstream segment, Superior. One of the conditions of that sale was the release of Superior from the terms of the credit agreement. Under the Fourth Amendment the amount we can borrow is the lesser of the amount we elect as the commitment amount or the value of the borrowing base as determined by the lenders, but in either event not to exceed $425.0 million. Our borrowing base and elected commitment is $425.0 million. The Superior sale closed on April 3, 2018 and the paydown under the credit agreement was made that same day.

The current lenders under our credit agreement and their respective participation interests are:
Lender

Interest
BOK (BOKF, NA, dba Bank of Oklahoma) 1718%
Compass Bank 1718%
BMO Harris Financing, Inc. 1516%
Bank of America, N.A. 1516%
Comerica Bank 8%
Wells Fargo Bank, N.A. 8%
Canadian Imperial Bank of Commerce 8%
Toronto Dominion (New York), LLC 8%
The Bank of Nova Scotia4%
  100%

The borrowing base amount–which is subject to redetermination by the lenders on April 1st and October 1st of each year–is based primarily on a percentage of the discounted future value of our oil and natural gas reserves. We or the lenders

may request a onetime special redetermination of the borrowing base between each scheduled redetermination. In addition, we may request a redetermination following the completion of an acquisition that meets the requirements in the credit agreement.


At our election, any part of the outstanding debt under the credit agreement maycould be fixed at a London Interbank Offered Rate (LIBOR). LIBOR interest is computed as the LIBOR base for the term plus 2.00% to 3.00% depending on the level of debt as a percentage of the borrowing base and is payable at the end of each term, or every 90 days, whichever is less. Borrowings not under LIBOR bear interest at the prime rate specified in the credit agreement that cannot be less than LIBOR plus 1.00% plus a margin. Interest is payable at the end of each month and the principal may be repaid in whole or in part at any time, without a premium or penalty. At June 30, 2017 and July 21, 2017,March 31, 2018, borrowings were $164.9 million and $172.1 million, respectively.$147.7 million. The outstanding balance was paid down on April 3, 2018.

We can use borrowings for financing general working capital requirements for (a) exploration, development, production, and acquisition of oil and gas properties, (b) acquisitions and operation of mid-stream assets, (c) issuance of standby letters of credit, (d) contract drilling services and acquisition of contract drilling equipment, and (e) general corporate purposes.

The credit agreement prohibits, among other things:

the payment of dividends (other than stock dividends) during any fiscal year over 30% of our consolidated net income for the preceding fiscal year;
the incurrence of additional debt with certain limited exceptions; and
the creation or existence of mortgages or liens, other than those in the ordinary course of business and with certain limited exceptions, on any of our properties, except in favor of our lenders.

The credit agreement also requires that we have at the end of each quarter:

a current ratio (as defined in the credit agreement) of not less than 1 to 1.

Through the quarter ending March 31, 2019, the credit agreement also requires that we have at the end of each quarter:

a senior indebtedness ratio of senior indebtedness to consolidated EBITDA (as defined in the credit agreement) for the most recently ended rolling four quarters of no greater than 2.75 to 1.

Beginning with the quarter ending June 30, 2019, and for each following quarter, the credit agreement requires:

a leverage ratio of funded debt to consolidated EBITDA (as defined in the credit agreement) for the most recently ended rolling four fiscal quarters of no greater than 4 to 1.

As of June 30, 2017,March 31, 2018, we were in compliance with the credit agreement covenants.

6.625% Senior Subordinated Notes. We have an aggregate principal amount of $650.0 million, 6.625% senior subordinated notes (the Notes) outstanding. Interest on the Notes is payable semi-annually (in arrears) on May 15 and November 15 of each year. The Notes mature on May 15, 2021. In issuing the Notes, we incurred fees of $14.7 million that are being amortized as debt issuance cost over the life of the Notes.

The Notes are subject to an Indenture dated as of May 18, 2011, between us and Wilmington Trust, National Association (successor to Wilmington Trust FSB), as Trustee (the Trustee), as supplemented by the First Supplemental Indenture dated as of May 18, 2011, between us, the Guarantors, and the Trustee, and as further supplemented by the Second Supplemental Indenture dated as of January 7, 2013, between us, the Guarantors, and the Trustee (as supplemented, the 2011 Indenture), establishing the terms of and providing for issuing the Notes. The Guarantors are most of our direct and indirect subsidiaries.subsidiaries, but excluding Superior. The discussion of the Notes in this report is qualified by and subject to the actual terms of the 2011 Indenture.

If a “change of control” occurs, subject to certain conditions, we must offer to repurchase from each holder all or any part of that holder’s Notes at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest to the date of purchase. The 2011 Indenture contains customary events of default. The 2011 Indenture also contains covenants

including those that limit our ability and the ability of certain of our subsidiaries to incur or guarantee additional indebtedness; pay dividends on our capital stock or redeem capital stock or subordinated indebtedness; transfer or sell assets; make investments; incur liens; enter into transactions with our affiliates; and merge or consolidate with other companies. We were in compliance with all covenants of the Notes as of June 30, 2017.March 31, 2018.

Capital Requirements

Oil and Natural Gas Segment Dispositions, Acquisitions, and Capital Expenditures. Most of our capital expenditures for this segment are discretionary and directed toward future growth. Our decisions to increase our oil, NGLs, and natural gas reserves through acquisitions or through drilling depends on the prevailing or expected market conditions, potential return on investment, future drilling potential, and opportunities to obtain financing under the circumstances which provide us with flexibility in deciding when and if to incur these costs. We completed drilling 1915 gross wells (8.21(5.40 net wells) in the first sixthree months of 20172018 compared to 13eight gross wells (7.65(3.96 net wells) in the first sixthree months of 2016.2017.

On April 3, 2017, we closed an acquisition of certain oil and natural gas assets located primarily in Grady and Caddo Counties in western Oklahoma. The preliminary adjusted value of consideration given was $54.0 million. As of January 1, 2017, the effective date of the acquisition, the estimated proved oil and gas reserves of the acquired properties were 3.2 million barrels of oil equivalent (MMBoe). The acquisition adds approximately 8,300 net oil and gas leasehold acres to our core Hoxbar area in southwestern Oklahoma including approximately 47 proved developed producing wells. This acquisition includes 13 potential horizontal drilling locations not otherwise included in our existing acreage. Of the acreage acquired, approximately 71% is held by production. We also received one gathering system as part of the transaction.

Capital expenditures for oil and gas properties on the full cost method for the first sixthree months of 20172018 by this segment, excluding $54.0less than $0.1 million for acquisitions and a $2.0$6.3 million in the ARO liability, totaled $86.6 million. Capital expenditures for the first three months of 2017, excluding $6.0 million for acquisition and a $0.9 million reduction in the ARO liability, totaled $84.5 million. Capital expenditures for the first six months of 2016, excluding a $28.9 million reduction in the ARO liability, totaled $76.2$37.9 million.

We plan to participateanticipate participating in drilling approximately 3575 to 4085 gross wells in 20172018 and our total estimated capital expenditures (excluding any possible acquisitions) for this segment are approximately $197.0$272.0 million. Whether we can drill the full number of wells planned depends on several factors, many of which are beyond our control, including the availability of drilling rigs, availability of pressure pumping services, prices for oil, NGLs, and natural gas, demand for oil, NGLs, and natural gas, the cost to drill wells, the weather, and the efforts of outside industry partners.

Contract Drilling Segment Dispositions, Acquisitions, and Capital Expenditures. During the first quarter of 2017, we were awarded a term contract to build our tenth BOSS drilling rig. Construction was completed and the drilling rig was placed into service late in the second quarter.

During the first quarter of 2018, we were awarded a term contract to build our eleventh BOSS drilling rig. Construction is in progress and the drilling rig will be placed into service early in the third quarter.

Our estimated 20172018 capital expenditures for this segment are approximately $28.0$47.0 million. At June 30, 2017,March 31, 2018, we had commitments to purchase approximately $3.9$3.4 million for drilling equipment over the next year. We have spent $22.7$8.9 million for capital expenditures during the first sixthree months of 2017,2018, compared to $5.2$7.3 million for capital expenditures during the first sixthree months of 2016.2017.

Mid-Stream Dispositions, Acquisitions, and Capital Expenditures. In the Appalachian region, our Pittsburgh Mills gathering system, in Allegheny and Butler counties, continues to produce consistent financial results. Our average gathered volume for the second quarter of 2017 is approximately 133 MMcf per day. We connected the new Allen well pad in May and it included five new wells. And we are constructing a pipeline to connect the Miller well pad, which will be the next pad connected to our system. The Miller pad will include seven new wells and we anticipate it will be ready to flow in the third quarter of 2018. Also, we anticipate several in-fill wells to be drilled and connected to our system in the first half of 2018.

At our Hemphill Texas system, our total throughput volume averaged 57.567.5 MMcf per day for the secondfirst quarter of 20172018 and our total production of natural gas liquids was approximately 142,000171,000 gallons per day. Total processing capacity at this facility is 135 MMcf per day. During the secondfirst quarter, we connected one new wellconstructed pipelines to connect several wells in the Buffalo Wallow area and sinceexpect these will begin flowing in the beginning of 2017, we connected two new wells to this processing facility.second quarter. Our oil and gas segment continues to operate a rig in the Buffalo Wallow area and we anticipate connecting four more wells in the third quarter.  are completing a construction project that will expand our compression capacity at our Buffalo Wallow compressor station to accommodate additional volumes.  

At our Cashion processing facility in central Oklahoma, our total throughput volume for the secondfirst quarter of 20172018 averaged approximately 37.842.6 MMcf per day and our total production of natural gas liquids increased to approximately 207,000224,700 gallons per day. Total processing capacity for this facility remains at approximately 45 MMcf per day.

At our Segno gathering facility in Southeast Texas, gathered volume for the secondfirst quarter of 20172018 averaged approximately 79.284.9 MMcf per day. At this facility, we have increased our gathering and dehydration capacity will allow us gather up to approximately 120 MMcf per day. We have connected one new well to this system in 2017.the first quarter of 2018 and the producer in this area is actively reworking and recompleting wells that are connected to our system which will continue to increase gathered volumes.

In the Appalachian region at our Pittsburgh Mills gathering system, our average gathered volume for the first quarter of 2018 is approximately 106.5 MMcf per day. We are currently constructing a new pipeline to connect the next well pad to our system. This pad will include seven new wells and we anticipate construction to be completed in the third quarter. Production from this new pad is expected to begin in the fourth quarter of 2018. Additionally, we are preparing to receive production from several infill wells that are currently being drilled on existing pads. These infill wells are expected to begin flow in the second quarter of this year.

On April 3, 2018, the company completed the sale of 50% of the ownership interests in Superior to SP Investor Holdings, LLC, a holding company jointly owned by OPTrust and funds managed and/or advised by Partners Group, a global private markets investment manager, for cash consideration of $300 million. Part of the proceeds from the sale were used to pay down our bank debt and the remainder will be used to accelerate the drilling program of our upstream subsidiary, Unit Petroleum Company, make additional capital investments in the jointly owned Superior, and for general working capital purposes.

During the first sixthree months of 2017,2018, our mid-stream segment incurred $5.4$7.3 million in capital expenditures as compared to $8.5$2.1 million in the first sixthree months of 2016.2017. For 2017,2018, our estimated capital expenditures are approximately $16.0$32.0 million.

(1)See previous discussion in MD&A regarding our long-term debt. This obligation is presented in accordance with the terms of the Notes and credit agreement and includes interest calculated using our June 30, 2017March 31, 2018 interest rates of 6.625% for the Notes and 3.5%3.8% for the credit agreement. Our credit agreement has a maturity date of April 10, 2020. The outstanding credit facility balance was paid down on April 3, 2018.

(2)We lease office space or yards in Edmond and Oklahoma City, Oklahoma; Houston, Texas; Englewood, Colorado; Pinedale, Wyoming; and Canonsburg, Pennsylvania under the terms of operating leases expiring through December 2021. Additionally, we have several equipment leases and lease space on short-term commitments to stack excess drilling rig equipment and production inventory.

(3)Maintenance and interest payments are included in our capital lease agreements. The capital leases are discounted using annual rates of 4.00%. Total maintenance and interest remaining are $6.8$5.4 million and $1.5$1.0 million, respectively.

(4)We have committed to pay $3.9$3.4 million for drilling rig components, drill pipe, and related equipment over the next year.


After March 31, 2018, we entered into a contractual obligation that commits us to spend $150.0 million for drilling wells in the Granite Wash/Buffalo Wallow area over the next three years starting January 1, 2019. This amount is already included in our drilling plan. For each dollar of the $150.0 million that we do not spend (over the three year period), we would forgo receiving $0.58 of future distributions from our 50% ownership interest in our consolidated mid-stream subsidiary. If we elected not to drill or spend any money in the designated area over the three year period, the maximum amount we could forgo from distributions would be $87.0 million.




At June 30, 2017,March 31, 2018, we also had the following commitments and contingencies that could create, increase, or accelerate our liabilities:

(1)We provide a salary deferral plan which allows participants to defer the recognition of salary for income tax purposes until actual distribution of benefits, which occurs at either termination of employment, death, or certain defined unforeseeable emergency hardships. We recognize payroll expense and record a liability, included in other long-term liabilities in our Unaudited Condensed Consolidated Balance Sheets, at the time of deferral.

(2)Effective January 1, 1997, we adopted a separation benefit plan (“Separation Plan”). The Separation Plan allows eligible employees whose employment is involuntarily terminated or, in the case of an employee who has completed 20 years of service, voluntarily or involuntarily terminated, to receive benefits equivalent to four weeks salary for every whole year of service completed with the company up to a maximum of 104 weeks. To receive payments the recipient must waive certain claims against us in exchange for receiving the separation benefits. On October 28, 1997, we adopted a Separation Benefit Plan for Senior Management (“Senior Plan”). The Senior Plan provides certain officers and key executives of the company with benefits generally equivalent to the Separation Plan. The Compensation Committee of the Board of Directors has absolute discretion in the selection of the individuals covered in this plan. Currently there are no participants in the Senior Plan. On May 5, 2004 we also adopted the Special Separation Benefit Plan (“Special Plan”). This plan is identical to the Separation Benefit Plan with the exception that the benefits under the plan vest on the earliest of a participant’s reaching the age of 65 or serving 20 years with the company.

(3)When a well is drilled or acquired, under ASC 410 “Accounting for Asset Retirement Obligations,” we record the discounted fair value of liabilities associated with the retirement of long-lived assets (mainly plugging and abandonment costs for our depleted wells).

(4)We have recorded a liability for those properties we believe do not have sufficient oil, NGLs, and natural gas reserves to allow the under-produced owners to recover their under-production from future production volumes.

(5)We formed The Unit 1984 Oil and Gas Limited Partnership and the 1986 Energy Income Limited Partnership along with private limited partnerships (the “Partnerships”) with certain qualified employees, officers and directors from 1984 through 2011. One of our subsidiaries serves as the general partner of each of these programs. Effective December 31, 2014, The Unit 1984 Oil and Gas Limited Partnership dissolved and effective December 31, 2016, the two 1986 partnerships were dissolved. The Partnerships were formed for the purpose of conducting oil and natural gas acquisition, drilling and development operations and serving as co-general partner with us in any additional limited partnerships formed during that year. The Partnerships participated on a proportionate basis with us in most drilling operations and most producing property acquisitions commenced by us for our own account during the period from the formation of the Partnership through December 31 of that year. These partnership agreements require, on the election of a limited partner, that we repurchase the limited partner’s interest at amounts to be determined by appraisal in the future. Repurchases in any one year are limited to 20% of the units outstanding. We did not have anyhad no repurchases duringin the first sixthree months of 20172018 or 2016.2017.

(6)We have recorded a liability for future estimated payments related to workers’ compensation claims primarily associated with our contract drilling segment.

(7)The amount includes commitments under capital lease arrangements for compressors in our mid-stream segment.

(8)We have recorded a liability related to the timing of revenue recognized on certain demand fees for our midstream segment.

Derivative Activities

Periodically we enter into derivative transactions locking in the prices to be received for a portion of our oil, NGLs, and natural gas production.








Commodity Derivatives. Our commodity derivatives are intended to reduce our exposure to price volatility and manage price risks. Our decision on the type and quantity of our production and the price(s) of our derivative(s) is based, in part, on our view of current and future market conditions. At June 30, 2017,March 31, 2018, based on our secondfirst quarter 20172018 average daily production, the approximated percentages of our production under derivative contracts are as follows:
 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q2 Q3 Q4
 2017 2018 2018
Daily oil production 48% 48% 48% 13% 13% 13% 13% 60% 60% 29%
Daily natural gas production 80% 80% 70% 61% 30% 30% 30% 73% 73% 73%
Daily NGLs production 11% 11% %

With respect to the commodities subject to derivative contracts, those contracts serve to limit the risk of adverse downward price movements. However, they also limit increases in future revenues that would otherwise result from price movements above the contracted prices.

The use of derivative transactions carries with it the risk that the counterparties may not be able to meet their financial obligations under the transactions. Based on our June 30, 2017March 31, 2018 evaluation, we believe the risk of non-performance by our counterparties is not material. At June 30, 2017,March 31, 2018, the fair values of the net assets (liabilities) we had with each of the counterparties to our commodity derivative transactions are as follows:
 June 30, 2017 March 31, 2018
 (In millions) (In millions)
Canadian Imperial Bank of Commerce $0.5
Bank of America (2.4)
Bank of Montreal $4.6
 (9.8)
Canadian Imperial Bank of Commerce (0.6)
Scotiabank (0.4)
Total assets $3.6
Total liabilities $(11.7)

If a legal right of set-off exists, we net the value of the derivative transactions we have with the same counterparty in our Unaudited Condensed Consolidated Balance Sheets. At June 30,March 31, 2018, we recorded the fair value of our commodity derivatives on our balance sheet as current derivative assets of $0.5 million, and current and non-current derivative liabilities of $12.1 million and $0.1 million, respectively. At December 31, 2017, we recorded the fair value of our commodity derivatives on our balance sheet as current and non-current derivative assets of $3.9 million and $0.7 million respectively, and current derivative liabilities of $1.0$7.8 million. At December 31, 2016, we recorded the fair value of our commodity derivatives on our balance sheet as non-current derivative assets of $0.4 million, and current and non-current derivative liabilities of $21.6 million and $0.4 million, respectively.

For our economic hedges any changes in their fair value occurring before their maturity (i.e., temporary fluctuations in value) are reported in gain (loss) on derivatives in our Unaudited Condensed Consolidated Statements of Operations.Income Statements. These gains (losses) at June 30March 31 are as follows:

Stock and Incentive Compensation

During the first sixthree months of 2017,2018, we granted awards covering 698,2761,201,568 shares of restricted stock. These awards had an estimated fair value as of their grant date of $17.2$23.4 million. Compensation expense will be recognized over the three year vesting periods, and during the sixthree months of 2017,2018, we recognized $2.9$1.0 million in compensation expense and capitalized $0.5$0.1 million for these awards. During the first sixthree months of 2017,2018, we recognized compensation expense of $5.8$4.6 million for all of our restricted stock stock options, and SAR grants and capitalized $0.8$1.3 million of compensation cost for oil and natural gas properties.


During the first sixthree months of 2016,2017, we granted awards covering 728,951614,172 shares of restricted stock. These awards had an estimated fair value as of their grant date of $4.3$15.4 million. Compensation expense will be recognized over the three year vesting periods, and during the sixthree months of 2016,2017, we recognized $0.6$0.8 million in compensation expense and capitalized less than $0.1$0.2 million for these awards. During the first sixthree months of 2016,2017, we recognized compensation expense of $5.3$2.6 million for all of our restricted stock, stock options, and SAR grants and capitalized $1.2$0.4 million of compensation cost for oil and natural gas properties.

Insurance

We are self-insured for certain losses relating to workers’ compensation, general liability, control of well, and employee medical benefits. Insured policies for other coverage contain deductibles or retentions per occurrence that range from zero to $1.0 million. We have purchased stop-loss coverage in order to limit, to the extent feasible, per occurrence and aggregate exposure to certain types of claims. There is no assurance that the insurance coverage we have will protect us against liability from all potential consequences. If insurance coverage becomes more expensive, we may choose to self-insure, decrease our limits, raise our deductibles, or any combination of these rather than pay higher premiums.

Oil and Natural Gas Limited Partnerships and Other Entity Relationships

We are the general partner of 13 oil and natural gas partnerships which were formed privately or publicly. Each partnership’s revenues and costs are shared under formulas set out in that partnership’s agreement. The partnerships repay us for contract drilling, well supervision, and general and administrative expense. Related party transactions for contract drilling and well supervision fees are the related party’s share of such costs. These costs are billed on the same basis as billings to unrelated third parties for similar services. General and administrative reimbursements consist of direct general and administrative expense incurred on the related party’s behalf as well as indirect expenses assigned to the related parties. Allocations are based on the related party’s level of activity and are considered by us to be reasonable. For the first sixthree months of 20172018 and 2016,2017, the total we received for all of these fees was less than $0.1 million and $0.2$0.1 million, respectively. Our proportionate share of assets, liabilities, and net income (loss) relating to the oil and natural gas partnerships is included in our unaudited condensed consolidated financial statements.

New Accounting Pronouncements

Compensation—Stock Compensation. The FASB issued ASU 2017-09, to clarify and reduce both (i) diversity in practice and (ii) cost and complexity when applying its guidance to changes in the terms and conditions of a share-based payment award. The amendments are effective for reporting periods beginning after December 15, 2017. We are in the process of evaluating the impact these amendments will have on our financial statements.

Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment. The FASB issued ASU 2017-04, to simplify the subsequent measurement of goodwill. The amendments eliminateamendment eliminates Step 2 from the goodwill impairment test. The amendmentsamendment will be effective prospectively for reporting periods beginning after December 31,15, 2019, and early adoption is permitted. We doThis amendment will not believe these amendments will have a material impact on our financial statements.

Business Combinations; Clarifying the Definition of a Business. The FASB issued ASU 2017-01, clarifying the definition of a business. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public companies, the amendments are effective for annual periods beginning after December 15, 2017. We are in the process of evaluating the impact these amendments will have on our financial statements.

Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments.  The FASB issued ASU 2016-15, to address diversity in how certain transactions are presented and classified in the statement of cash flows. The amendments

will be effective retrospectively for reporting periods beginning after December 31, 2017, and early adoption is permitted. We do not believe these amendments will have a material impact on our financial statements.

Leases. The FASB has issued ASU 2016-02. The amendmentsamendment will require lessees to recognize at the commencement date a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee's right to use a specified asset for the lease term. Lessor accounting is largely unchanged. In January 2018, the FASB issued ASU 2018-01, "Leases - Land Easement practical expedient for Transition to Topic 842", which provides clarifying guidance regarding land easements and adds practical expedients. For public companies, the amendments areamendment is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. Early adoptionThe standard will not apply to leases of mineral rights. We have begun the identification of leases and impact assessment within the scope of the amendments is permitted. We are in the processguidance. Our evaluation of evaluating the impact these amendments will haveof the new guidance on our financial statements in on-going.

Adopted Standards

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The FASB issued ASU 2018-02, an amendment which provides financial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings caused by the Tax Cuts and Jobs Act of 2017. The amendment is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Organizations should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. We adopted this amendment early and it did not have a material effect to our financial statements. We previously used 37.75% to calculate the tax effect on AOCI and now we are using 24.5%. The change is reflected in our Unaudited Condensed Consolidated Statements of Comprehensive Income and in Note 13 - Equity.

Revenue from Contracts with Customers. Effective January 1, 2018, the company adopted ASC 606. The FASB has issued ASU 2014-09. These amendments affect any entity using U.S. GAAP that either enters into contracts with customersnew revenue standard provides a five-step analysis of transactions to transfer goods or services or enters into contracts fordetermine when and how revenue is recognized. The guidance in this update supersedes the transfer of nonfinancial assets unless those contracts are withinrevenue recognition requirements in ASC 605, Revenue Recognition, and most industry-specific guidance throughout the scope of other standards (e.g., insurance contracts or lease contracts). The core principleIndustry Topics of the amendmentsCodification. Under the standard, revenue is that an entity should recognize revenue to depict the transferrecognized when a customer obtains control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitledreceive in exchange for those goods or services. In May 2016,addition, the FASB issuedstandard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The company applied the five step method outlined in the ASU 2016-12, "Narrow-Scope Improvementsto all revenue streams in the scope of ASC 606 and Practical Expedients," which provides clarifying guidanceelected the modified retrospective approach method. Under that approach the cumulative effect on adoption is recognized as an adjustment to opening retained earnings at January 1, 2018. Only our mid-stream segment was affected. This adjustment related to the timing of revenue on certain demand fees. Both our oil and natural gas and contract drilling segments had no retained earnings adjustment. Comparative prior periods have not been adjusted and continue to be reported under ASC 605.

The additional disclosures required by ASC 606 have been included in certain areas and adds some practical expedients. Also in May 2016, the FASB issued ASU 2016-11, "Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting." This amendment rescinds SEC Staff Observer comments that are codified in Topic 605, Revenue Recognition, and Topic 932, Extractive Activities- Oil and Gas, effective on the adoption of Topic 606,Note 2 – Revenue from Contracts with Customers. In April 2016,

Our internal control framework did not materially change, but the FASB issued ASU 2016-10, "Identifying Performance Obligations and Licensing," which amends theexisting internal controls have been modified to consider our new revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. The FASB has issued 2015-14, which defers the effective date to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. We will adopt these amendmentsrecognition policy effective January 1, 2018. We are utilizing a bottom-up approach to analyze the impact ofAs we implement the new standard, on our contracts by reviewing our current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard. We have an implementation team evaluating contracts for the various revenue streams of our business segments to address changes to business processes, systems, and controls. While we have not identified any material differences inadded internal controls to ensure that we adequately evaluate new contracts under the amount and timing of revenue recognition to date, our evaluation is not complete, and we have not reached a conclusion on the overall impacts of adopting Topic 606. Topic 606 provides for adoption either retrospectively to each prior reporting period presented or as a cumulative effect adjustment to retained earnings at the date of adoption. We plan to adopt using the cumulative effect method.

Adopted Standards

Income Taxes: Balance Sheet Classification of Deferred Taxes. The FASB has issuedfive-step model under ASU 2015-17. This changes how deferred taxes are classified on organizations' balance sheets. Organizations are required to classify all deferred tax assets and liabilities as noncurrent. The amendments apply to all organizations that present a classified balance sheet. For public companies, the amendments were effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The amendments require current deferred tax assets to be combined with noncurrent deferred tax assets. We have adopted this ASU during the first quarter of 2017 on a prospective basis. Previously, we had a net current deferred tax asset which is now netted with our noncurrent deferred tax liability. Prior periods were not retrospectively adjusted.

Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting. The FASB has issued ASU 2016-09. The amendments are intended to improve the accounting for employee share-based payments and affect all organizations that issue share-based payment awards to their employees. Several aspects of the accounting for share-based payment award transactions are simplified, including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the statement of cash flows. For public companies, the amendments were effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The amendments primarily impact classification within the statement of cash flows between financial and operating activities. This did not have a material impact on our financial statements.

Oil and Natural Gas

Oil and natural gas revenues increased $14.0 million or 20% in the second quarter ofMarch 31, 2017 as compared to the second quarter of 2016 primarily due to higher commodity prices partially offset from reduced production volumes. In the second quarter of 2017, as compared to the second quarter of 2016, oil production decreased 6%, natural gas production decreased 17%, and NGLs production decreased 5%. Average oil prices increased 13% to $46.96 per barrel, average natural gas prices increased 36% to $2.45 per Mcf, and NGLs prices increased 31% to $14.91 per barrel.

Oil and natural gas operating costs decreased $0.6 million or 2% between the comparative second quarters of 2017 and 2016 due to lower LOE and saltwater disposal expenses partially offset by higher general and administrative expenses.

Depreciation, depletion, and amortization (“DD&A”) decreased $6.9 million or 23% due primarily to a 13% decrease in our DD&A rate and a 12% decrease in equivalent production. The decrease in our DD&A rate in the second quarter of 2017 compared to the second quarter of 2016 resulted primarily from the effect of the ceiling test write-downs throughout 2016.

During the second quarter of 2016, we recorded a non-cash ceiling test write-down of $74.3 million pre-tax ($46.3 million, net of tax). We did not have a write-down for the second quarter of 2017.

Contract Drilling

Drilling revenues increased $15.0 million or 62% in the second quarter of 2017 versus the second quarter of 2016. The increase was due primarily to a 113% increase in the average number of drilling rigs in use partially offset by a 14% decrease in the average dayrate. Average drilling rig utilization increased from 13.5 drilling rigs in the second quarter of 2016 to 28.8 drilling rigs in the second quarter of 2017. We recorded $0.8 million in early termination revenue in the second quarter of 2017 compared to $0.4 million in the second quarter of 2016.

Drilling operating costs increased $8.0 million or 41% between the comparative second quarters of 2017 and 2016. The increase was due primarily to more drilling rigs operating partially offset by decreases in per day cost. Contract drilling depreciation increased $2.9 million or 26% also due primarily to more drilling rigs operating.

Mid-Stream

Our mid-stream revenues increased $3.3 million or 7% in the second quarter of 2017 as compared to the second quarter of 2016 due primarily to increases in gas, NGLs, and condensate prices. Gas processed volumes per day decreased 16% between the comparative quarters primarily due to declines in existing volumes, fewer new wells connected to our processing systems, and the loss of an offload volume at our Hemphill facility in mid-2016. Gas gathered volumes per day decreased 13% between the comparative quarters primarily due to declines in existing volumes, fewer new wells connected to our gathering systems, and the loss of an offload volume at our Hemphill facility in mid-2016.

Operating costs increased $3.7 million or 11% in the second quarter of 2017 compared to the second quarter of 2016 primarily due to increases in gas, NGLs, and condensate prices partially offset by a decrease in gas processed volumes along with a decrease in field direct operating expenses. Depreciation and amortization decreased $0.7 million, or 6%, primarily due to certain assets being fully depreciated in 2017.

Other Depreciation

During the second quarter of 2017, we had $1.9 million of other depreciation primarily due to our new ERP accounting and reporting system that was implemented during the first quarter of 2017 as well as depreciation on our corporate building.

General and Administrative

Corporate general and administrative expenses increased $0.4 million or 4% in the second quarter of 2017 compared to the second quarter of 2016 primarily due to an increase in employee costs.

Gain on Disposition of Assets

There was a $0.2 million gain on disposition of assets in the second quarter of 2017 primarily due to the sale of vehicles compared to a gain of $0.5 million for the disposition of assets in the second quarter of 2016 primarily due to the sale of two top drives and power units, several large trucks, trailers, forklifts, and smaller vehicles.

Other Income (Expense)

Interest expense, net of capitalized interest, decreased $1.1 million between the comparative second quarters of 2017 and 2016 due primarily to a 10% decrease in average long-term debt outstanding in the second quarter of 2017. We capitalized interest based on the net book value associated with undeveloped leasehold not being amortized, the construction of additional drilling rigs, and the construction of gas gathering systems. Capitalized interest for the second quarter of 2017 was $4.0 million compared to $3.6 million in the second quarter of 2016, and was netted against our gross interest of $13.5 million and $14.2 million for the second quarters of 2017 and 2016, respectively. Our average interest rate increased from 5.6% in the second quarter of 2016 to 6.0% in the second quarter of 2017 and our average debt outstanding was $91.8 million lower in the second quarter of 2017 as compared to the second quarter of 2016 primarily due to the decrease in outstanding borrowings under our credit agreement over the comparative periods.

Gain (loss) on derivatives increased $31.6 million primarily due to fluctuations in forward prices used to estimate the fair value in mark-to-market accounting.

Income Tax Expense (Benefit)

Income tax expense increased $49.2 million between the comparative second quarters of 2017 and 2016 primarily due to increased pre-tax income. Our effective tax rate was 41.3% for the second quarter of 2017 compared to 37.3% for the first quarter of 2016. The rate change was primarily due to increased deferred income tax expense related to non-qualified stock options that expired and were forfeited during the second quarter of 2017. There was no current income tax expense or benefit in the first quarter of 2017 or 2016. We did not pay any income taxes in the second quarter of 2017.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

Our operations are exposed to market risks primarily because of changes in commodity prices and interest rates.

Commodity Price Risk. Our major market risk exposure is in the prices we receive for our oil, NGLs, and natural gas production. These prices are primarily driven by the prevailing worldwide price for crude oil and market prices applicable to our NGLs and natural gas production. Historically, these prices have fluctuated and we expect this to continue. The prices for oil, NGLs, and natural gas also affect the demand for our drilling rigs and the amount we can charge for the use of our drilling rigs. Based on our first six months 2017 production, a $0.10 per Mcf change in what we are paid for our natural gas production, without the effect of hedging, would result in a corresponding $392,000 per month ($4.7 million annualized) change in our pre-tax operating cash flow. A $1.00 per barrel change in our oil price, without the effect of hedging, would have a $219,000 per month ($2.6 million annualized) change in our pre-tax operating cash flow and a $1.00 per barrel change in our NGLs prices,

without the effect of hedging, would have a $362,000 per month ($4.3 million annualized) change in our pre-tax operating cash flow.

We use derivative transactions to manage the risk associated with price volatility. Our decisions regarding the amount and prices at which we choose to enter into a contract for certain of our products is based, in part, on our view of current and future market conditions. The transactions we use include financial price swaps under which we will receive a fixed price for our production and pay a variable market price to the contract counterparty. We do not hold or issue derivative instruments for speculative trading purposes.

Interest Rate Risk. Our interest rate exposure relates to our long-term debt under our credit agreement and the Notes. The credit agreement, at our election bears interest at variable rates based on the Prime Rate or the LIBOR Rate. At our election, borrowings under our credit agreement may be fixed at the LIBOR Rate for periods of up to 180 days. Based on our average outstanding long-term debt subject to a variable rate in the first six months of 2017, a 1% increase in the floating rate would reduce our annual pre-tax cash flow by approximately $1.6 million. Under our Notes, we pay a fixed rate of interest of 6.625% per year (payable semi-annually in arrears on May 15 and November 15 of each year).

Item 4. Controls and Procedures

Our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), does not expect that our disclosure controls and procedures (as defined in Rules 13a - 15(e) and 15d - 15(e) of the Securities Exchange Act of 1934, as amended (the Exchange Act)) (Disclosure Controls) or our internal control over financial reporting (ICFR) will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part on certain assumptions about the likelihood of future events, and there is no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to an error or fraud may occur and not be detected. We monitor our Disclosure Controls and ICFR and make modifications as necessary; our intent in this regard is that the Disclosure Controls and ICFR will be modified as systems change, and conditions warrant.

Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this report in connection with the Original Filing on May 3, 2018, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive OfficerCEO and Chief Financial Officer,CFO, of the effectiveness of the design and operation of our disclosure controls and procedures under Exchange Act Rule 13a-15.Disclosure Controls. Based on that evaluation, our Chief Executive OfficerCEO and Chief Financial OfficerCFO concluded that our disclosure controls and procedures areDisclosure Controls were effective as of June 30, 2017March 31, 2018 in ensuringproviding reasonable assurance the appropriate information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in our periodic SEC filingsthe Commission’s rules and forms relating to the company (including its consolidated subsidiaries) and is accumulated and communicated to the Chief Executive Officer, Chief Financial Officer,CEO, CFO, and management as appropriate to allow timely decisions.decisions regarding required disclosure. After the evaluation made in connection with the Original Filing, our management, with the participation of the CEO and CFO, reevaluated the effectiveness of the design and operation of our Disclosure Controls and concluded that our Disclosure Controls were not effective as of March 31, 2018 due to a material weakness in ICFR described below.

ChangesMaterial Weakness in Internal Controls.Control Over Financial Reporting. A material weakness is a deficiency, or combination of deficiencies, in ICFR, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis.

We did not design and maintain effective controls to verify the proper presentation and disclosure of the interim and annual consolidated financial statements. Specifically, our controls were not sufficiently precise to allow for the effective review of the underlying information used in the preparation of the consolidated financial statements, nor verify that transactions were appropriately presented.The material weakness resulted in the revision of the Company's consolidated financial statements for the year ended 2017 and the restatement of the Company’s condensed consolidated financial statements for the quarter ended March 31, 2018. This material weakness could result in misstatements of the annual or interim consolidated financial statements or disclosures that would not be prevented or detected. Accordingly, our management has determined that this control deficiency constitutes a material weakness.

Plan for Remediation of Material Weakness. In January 2017, we implemented a new ERP accountingthe second quarter of 2018, management became actively engaged in the planning for, and reporting system designedimplementation of, remediation efforts to upgrade our technology and improveaddress the timeliness and quality of our financial and operational information. This new ERP system was not implemented in response to any material weakness in our internal control over financial reporting. TheSpecifically, we are taking steps that we believe will address the underlying cause of the material weakness, including a redesign of the control related to the preparation and review of the consolidated financial statements, as well as the need to conduct enhanced controls and policy training for employees responsible for preparing and reviewing of the consolidated financial statements.

As management continues to evaluate and improve internal control over financial reporting, and requires ongoing testing for effectiveness. The adoptionwe may decide to take additional measures to address this control deficiency or determine to modify, or in appropriate circumstances not to complete, certain of this new ERP system hasthe remediation measures identified.

Changes in Internal Control over Financial Reporting. Our internal control framework did not materially affected ourchange, but the existing internal controls over financial reporting.were modified to consider our new revenue recognition policy effective January 1, 2018. We have added internal controls to ensure that we adequately evaluate new contracts under the five-step model under ASU 2014-09. There were no other changes in our internal controls over financial reportingICFR during the quarter ended June 30, 2017March 31, 2018, that have materially affected our ICFR or are reasonably likely to materially affect our internal control over financial reporting,it, as defined in Rule 13a – 15(f) under the Exchange Act.


PART II. OTHER INFORMATION
Item 1. Legal Proceedings

Panola Independent School District No. 4, et al. v. Unit Petroleum Company, No. CJ-07-215, District Court of Latimer County, Oklahoma.

Panola Independent School District No. 4, Michael Kilpatrick, Gwen Grego, Carla Lessel, Thelma Christine Pate, Juanita Golightly, Melody Culberson, and Charlotte Abernathy are the Plaintiffs in this case and are royalty owners in oil and gas drilling and spacing units for which the company’s exploration segment distributes royalty. The Plaintiffs’ central allegation is that the company’s exploration segment has underpaid royalty obligations by deducting post-production costs or marketing related fees. Plaintiffs sought to pursue the case as a class action on behalf of persons who receive royalty from us for our Oklahoma production. We have asserted several defenses including that the deductions are permitted under Oklahoma law. We have also asserted that the case should not be tried as a class action due to the materially different circumstances that determine what, if any, deductions are taken for each lease. On December 16, 2009, the trial court entered its order certifying the class. On May 11, 2012 the court of civil appeals reversed the trial court’s order certifying the class. The Plaintiffs petitioned the supreme court for certiorari and on October 8, 2012, the Plaintiff’s petition was denied. On January 22, 2013, the Plaintiffs filed a second request to certify a class of royalty owners that was slightly smaller than their first attempt. Since then, the Plaintiffs have further amended their proposed class to just include royalty owners entitled to royalties under certain leases located in Latimer, Le Flore, and Pittsburg Counties, Oklahoma. In July 2014, a second class certification hearing was held where, in addition to the defenses described above, we argued that the amended class definition is still deficient under the court of civil appeals opinion reversing the initial class certification. Closing arguments were held on December 2, 2014. There is no timetable for when the court will issue its ruling. The merits of Plaintiffs’ claims will remain stayed while class certification issues are pending.

Cockerell Oil Properties, Ltd., v. Unit Petroleum Company, No. 16-cv-135-JHP, United States District Court for the Eastern District of Oklahoma.

On March 11, 2016, a putative class action lawsuit was filed against Unit Petroleum Company styled Cockerell Oil Properties, Ltd., v. Unit Petroleum Company in LeFlore County, Oklahoma. We removed the case to federal court in the Eastern District of Oklahoma. The plaintiff alleges that Unit Petroleum wrongfully failed to pay interest with respect to untimely royalty payments under Oklahoma’s Production Revenue Standards Act. The lawsuit seeks actual and punitive damages, an accounting, disgorgement, injunctive relief, and attorney’s fees. Plaintiff is seeking relief on behalf of royalty owners in our Oklahoma wells. We have asserted several defenses including that the case cannot be properly certified as a class action because of the wide variety of circumstances that determine whether a royalty payment was timely made or has accrued interest under Oklahoma law. At this point, the court has not taken any action on the issue of class certification.

We continue to vigorously defend against each of the pending claims. At this time we are unable to express an opinion with respect to the likelihood of an unfavorable outcome or provide an estimate of potential losses, if any.

Item 1A. Risk Factors

In addition to the other information set forth in this quarterly report, you should carefully consider the factors discussed below, if any, and in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016, which could materially affect our business, financial condition, or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, and/or operating results.

Except as set forth below, there have been no material changes to the risk factors disclosed in Item 1A in our Form 10-K for the year ended December 31, 2016.

We are the subject of putative class action lawsuits that may result in substantial expenditures and divert management's attention.

We are the subject of putative class action lawsuits in Oklahoma with respect to the alleged failure to pay interest with on untimely royalty payments and with respect to the alleged underpayment of royalties. These lawsuits seek various remedies, including damages, injunctive relief, and attorney’s fees. For additional information on these lawsuits, see Item 1 Legal Proceedings in this Quarterly Report on Form 10-Q.

Although we believe that the allegations in these lawsuits are without merit and intend to defend such litigation vigorously, litigation is subject to inherent uncertainties, and an adverse result in one of these lawsuits or other matters that may arise from time to time could have a material adverse effect on our business, results of operations and financial condition. Defending the lawsuits may be costly and, further, could require significant involvement of our senior management and may divert management's attention from our business and operations.
