“productive well” A well found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of the production exceed production expenses and taxes.

ii


“prospect” A potential geological feature or formation which geologists and geophysicists believe may contain hydrocarbons. A prospect can be in various stages of evaluation, ranging from a prospect that has been fully evaluated and is ready to drill to a prospect that will require substantial additional seismic data processing and interpretation.

“proved reserves” The quantities of crude oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs and under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates renewal is reasonably certain.

“proved developed reserves” Reserves expected to be recovered through existing wells with existing equipment and operating methods.

“proved undeveloped reserves” or“PUD” Proved reserves expected to be recovered from new wells on undrilled acreage or from existing wells where a relatively major expenditure is required for recompletion.

“PV-10” When used with respect to crude oil and natural gas reserves, PV-10 represents the estimated future gross revenuerevenues to be generated from the production of proved reserves using a 12-month unweighted arithmetic average of the first-day-of-the-month commodity prices for the period of January to December, net of estimated production and future development and abandonment costs using prices andbased on costs in effect at the determination date, before income taxes, and without giving effect to non-property-related expenses, discounted to a present value using an annual discount rate of 10% in accordance with the guidelines of the Securities and Exchange Commission (“SEC”). PV-10 is not a financial measure calculated in accordance with generally accepted accounting principles (“GAAP”) and generally differs from Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effects of income taxes on future net revenues. Neither PV-10 nor Standardized Measure represents an estimate of the fair market value of the Company’s crude oil and natural gas properties. The Company and others in the industry use PV-10 as a measure to compare the relative size and value of proved reserves held by companies without regard to the specific tax characteristics of such entities.

“reservoir” A porous and permeable underground formation containing a natural accumulation of producible crude oil and/or natural gas that is confined by impermeable rock or water barriers and is separate from other reservoirs.


ii



“resource play” Refers to an expansive contiguous geographical area with prospective crude oil and/or natural gas reserves that has the potential to be developed uniformly with repeatable commercial success due to advancements in horizontal drilling and multi-stage fracturingcompletion technologies.

“royalty interest” Refers to the ownership of a percentage of the resources or revenues produced from a crude oil or natural gas property. A royalty interest owner does not bear exploration, development, or operating expenses associated with drilling and producing a crude oil or natural gas property.

“SCOOP” Refers to the South Central Oklahoma Oil Province, a term we use to describe an emerging area of crude oil and liquids-rich natural gas properties located in the Anadarko basinBasin of Oklahoma in which we operate.
“STACK” Refers to Sooner Trend Anadarko Canadian Kingfisher, a term used to describe properties located in the Anadarko Basin of Oklahoma Woodford formation.in which we operate.

“spacing” The distance between wells producing from the same reservoir. Spacing is often expressed in terms of acres (e.g., 640-acre spacing) and is often established by regulatory agencies.

“standardized measure” Discounted future net cash flows estimated by applying the 12-month unweighted arithmetic average of the first-day-of-the-month commodity prices for the period of January to December to the estimated future production of year-end proved reserves. Future cash inflows are reduced by estimated future production and development costs based on period-end costs to determine pre-tax net cash inflows. Future income taxes, if applicable, are computed by applying the statutory tax rate to the excess of pre-tax cash inflows over the tax basis in the crude oil and natural gas properties. Future net cash inflows after income taxes are discounted using a 10% annual discount rate.

“step-out well” or“step outs” A well drilled beyond the proved boundaries of a field to investigate a possible extension of the field.

iii


3D (threethree dimensional seismic) defined locations” Locations that have been subjected to 3D seismic testing. We typically use 3D seismic testing to evaluate reservoir presence and/or continuity. We do not typically evaluate reservoir productivity using 3D seismic technology.(3D) seismic”

“3D seismic” Seismic surveys using an instrument to send sound waves into the earth and collect data to help geophysicists define the underground configurations. 3D seismic provides three-dimensional pictures. We typically use 3D seismic testing to evaluate reservoir presence and/or continuity. We also use 3D seismic to identify sub-surface hazards to assist in steering, avoiding hazards and determining where to perform enhanced completions.

“unconventional play” An area believed to be capable of producing crude oil and natural gas occurring in accumulations that are regionally extensive, but require recently developed technologies to achieve profitability.may lack readily apparent traps, seals and discrete hydrocarbon-water boundaries that typically define conventional reservoirs. These areas tend to have low permeability and may be closely associated with source rock, as is the case with oil and gas shale, tight oil and gas sands and coalbed methane.methane, and generally require horizontal drilling, fracture stimulation treatments or other special recovery processes in order to achieve economic production. In general, unconventional plays require the application of more advanced technology and higher drilling and completion costs to produce relative to conventional plays.

“undeveloped acreage” Lease acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of crude oil and/or natural gas.

“unit” The joining of all or substantially all interests in a reservoir or field, rather than a single tract, to provide for development and operation without regard to separate property interests. Also, the area covered by a unitization agreement.

waterflood” The injection of water into a crude oil reservoir to “push” additional crude oil out of the reservoir rock and into the wellbores of producing wells. Typically an enhanced recovery process.well bore”

“wellbore” The hole drilled by the bit that is equipped for crude oil or natural gas production on a completed well. Also called a well or borehole.

“working interest” The right granted to the lessee of a property to explore for and to produce and own crude oil, natural gas, or other minerals. The working interest owners bear the exploration, development, and operating costs on either a cash, penalty, or carried basis.

Item 1.Business

General

We are an independent crude oil and natural gas exploration and production company with properties in the North, South and East regions of the United States. The North region consists of properties north of Kansas and west of the Mississippi River and includes North Dakota Bakken, Montana Bakken, and the Red River units. The South region includes Kansas and all properties south of Kansas and west of the Mississippi River including various plays in the SouthSCOOP (South Central Oklahoma Oil Province (“SCOOP”)Province), STACK (Sooner Trend Anadarko Canadian Kingfisher), Northwest Cana and Arkoma Woodford plays inareas of Oklahoma. The SCOOP and Northwest Cana plays were previously combined by the Company and referred to as the Anadarko Woodford play. In December 2012, we sold the producing crude oil and natural gas properties in our East region. Our remaining East region properties areis comprised of undeveloped leasehold acreage east of the Mississippi River that will be managed as part of our exploration program.

with no current drilling or production operations.

We were originally formed in 1967 to explore for, develop and produce crude oil and natural gas properties. Through 1989,the late 1980s, our activities and growth remained focused primarily in Oklahoma. In 1989,the late 1980s, we expanded our activity into the North region.region, where a substantial portion of our operations is now concentrated due to our successful leasing and drilling activities in the Bakken field. The North region comprised approximately 68% of our crude oil and natural gas production and approximately 77% of our crude oil and natural gas revenues for the year ended December 31, 2015. Approximately 82%58% of our estimated proved reserves as of December 31, 20122015 are located in the North region. We completed an initial public offeringIn recent years, we have significantly expanded our activity in our South region resulting from our discovery of the SCOOP play and our increased activity in the Northwest Cana and STACK plays, all of which are located in Oklahoma. Our South region comprised approximately 32% of our common stock in 2007,crude oil and natural gas production, 23% of our common stock tradescrude oil and natural gas revenues, and 42% of our estimated proved reserves as of and for the year ended December 31, 2015.
We have focused our operations on the New York Stock Exchange underexploration and development of crude oil since the ticker symbol “CLR”.

1980s. For the year ended December 31, 2015, crude oil accounted for approximately 66% of our total production and approximately 85% of our crude oil and natural gas revenues. Crude oil represents approximately 57% of our estimated proved reserves as of December 31, 2015.

We focus our exploration activities in large new or developing crude oil and liquids-rich natural gas plays that provide us the opportunity to acquire undeveloped acreage positions for future drilling operations. We have been successful in targeting large repeatable resource plays where three dimensional seismic, horizontal drilling, geosteering technologies, advanced completion technologies (e.g., fracture stimulationstimulation) and enhanced recovery technologies allow us to economically develop and produce crude oil and natural gas reserves from unconventional formations. As a result of these efforts, we have grown substantially through the drill bit, adding 649.0 MMBoe of proved crude oil and natural gas reserves through extensions and discoveries from January 1, 2008 through December 31, 2012 compared to 86.7 MMBoe added through proved reserve acquisitions during that same period. In October 2012, we announced a new five-year growth plan to triple our production and proved reserves from year-end 2012 to year-end 2017.

bit.

As of December 31, 2012,2015, our estimated proved reserves were 784.71,226 MMBoe, with estimated proved developed reserves of 317.8525 MMBoe, or 40%43% of our total estimated proved reserves. Crude oil comprised 72% of our total estimated proved reserves as of December 31, 2012. For the year ended December 31, 2012,2015, we generated crude oil and natural gas revenues of $2.4$2.6 billion and operating cash flows of $1.6$1.9 billion. For the year ended December 31, 2012, daily2015, production averaged 97,583221,715 Boe per day, a 58%27% increase over average production of 61,865174,189 Boe per day for the year ended December 31, 2011.2014. Average daily production for the quarter ended December 31, 20122015 increased 42%16% to 106,831224,936 Boe per day from 75,219193,456 Boe per day for the quarter ended December 31, 2011.

2014.

The following table below summarizes our total estimated proved reserves, PV-10 and net producing wells as of December 31, 2012,2015, average daily production for the quarter ended December 31, 20122015 and the reserve-to-production index in our principal regions. Our reserve estimates asoperating areas. The PV-10 values shown below are not intended to represent the fair market value of December 31, 2012 are based primarily on a reserve report prepared by our independent reserve engineers, Ryder Scott Company, L.P (“Ryder Scott”). In preparing its report, Ryder Scott evaluated properties representing approximately 99% of our PV-10, 99% of our proved crude oil reserves, and 96% of our proved natural gas reserves as of December 31, 2012. Our internal technical staff evaluated the remaining properties. Our estimated proved reserves and related future net revenues, PV-10 and Standardized Measure at December 31, 2012 were determined using the 12-month unweighted

arithmetic average of the first-day-of-the-month commodity prices for the period of January 2012 through December 2012, without giving effect to derivative transactions, and were held constant throughout the lives of the properties. These prices were $94.71 per Bbl for crude oil and $2.76 per MMBtu for natural gas ($86.56 per Bbl forproperties. There are numerous uncertainties inherent in estimating quantities of crude oil and $4.31 per Mcf for natural gas adjustedreserves. See Part I, Item 1A.

Industry Operating Environment and Outlook
Crude oil prices remained significantly depressed in 2015 and face continued downward pressure due to domestic and global supply and demand factors. The following table provides additional informationdownward price pressure intensified in late 2015 and early 2016, with crude oil prices dropping below $27 per barrel in February 2016, a level not seen since 2003. Natural gas prices faced similar downward pressure in 2015, dropping below $1.70 per MMBtu in December 2015.
In response to these price declines, and given the uncertainty regarding the timing and magnitude of any price recovery, we have significantly reduced our key development areas asplanned non-acquisition capital spending for 2016 to $920 million, a reduction of 63% compared to $2.50 billion of non-acquisition capital spending in 2015. This non-acquisition investment level is designed to target capital expenditures and cash flows being relatively balanced for 2016 at an assumed average West Texas Intermediate benchmark crude oil price of approximately $37 per barrel for the year, with any cash flow deficiencies being funded by borrowings under our revolving credit facility. Our reduced spending is projected to result in a decrease in our 2016 average daily production of approximately 10% compared to 2015.
With reduced capital spending planned for 2016, we will be growing our drilled but uncompleted ("DUC") well inventory. Our DUC inventory in North Dakota is expected to increase from 135 gross operated wells at December 31, 20122015 to approximately 195 gross operated wells at year-end 2016. Our DUC inventory in Oklahoma is expected to increase from 35 gross operated wells at December 31, 2015 to approximately 50 gross operated wells at year-end 2016. We will continue to monitor our capital spending closely based on actual and projected cash flows and could make additional reductions to our 2016 capital spending should commodity prices decrease further. Conversely, a significant improvement in commodity prices could result in an increase in our capital expenditures.
In light of the budgeted amounts we planchallenges facing our industry, our primary business strategies for 2016 will include: (1) optimizing cash flows through operating efficiencies and cost reductions, (2) high-grading investments based on rates of return and opportunities to spend on exploratoryconvert undeveloped acreage to acreage held by production, and development drilling,(3) working to balance capital workovers,spending with cash flows to

(1)The capital expenditures budgeted for 2013 as reflected above include amounts for drilling, capital workovers and facilities and exclude budgeted amounts for land of $220 million, seismic of $20 million, and $30 million for vehicles, computers and other equipment. Potential acquisition expenditures are not budgeted. We expect our cash flows from operations, our remaining cash balance, and our revolving credit facility, including our ability to increase our borrowing capacity thereunder, will be sufficient to satisfy our 2013 capital budget. We may choose to access the capital markets for additional financing to take advantage of business opportunities that may arise if such financing can be arranged at favorable terms. The actual amount and timing of our capital expenditures may differ materially from our estimates as a result of, among other things, available cash flows, unbudgeted acquisitions, actual drilling results, the availability of drilling rigs and other services and equipment, the availability of transportation capacity, and regulatory, technological and competitive developments. Further, a decline in crude oil and natural gas prices could cause us to curtail our actual capital expenditures. Conversely, an increase in commodity prices could result in increased capital expenditures.

See the section below titled Summary of Crude Oil and Natural Gas Properties and Projects for further discussion of our 2016 plans. Also see Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for discussion of our 2015 operating results and potential impact on 2016 operating results due to depressed commodity prices.
Our goalBusiness Strategy
Despite a reduced capital budget for 2016 that is reflective of the current commodity price environment, our business strategy continues to increasebe focused on increasing shareholder value by finding and developing crude oil and natural gas reserves at costs that provide an attractive raterates of return on our investment.return. The principal elements of our businessthis strategy are:

include:

FocusGrowing and sustaining a premier portfolio of assets focused on crude oil. During the late 1980s we beganhigh rate-of-return projects. We hold a portfolio of leasehold acreage and drilling opportunities in certain premier U.S. resource plays with varying exposure to believe the valuation potential for crude oil, exceedednatural gas, and natural gas liquids. We pursue opportunities to develop our existing properties as well as explore for new resource plays where significant reserves may be economically developed. Our capital programs are designed to allocate investments to projects that provide opportunities to convert undeveloped acreage to acreage held by production and to maximize hydrocarbon recoveries and rates of natural gas. Accordingly, we began to shift our reservereturn on capital employed. Our operations are primarily focused on the exploration and production profiles toward crude oil. Asdevelopment of December 31, 2012, crude oil, comprised 72% of our total proved reserves and 70% of our 2012 annual production. Althoughbut we do pursuealso allocate capital to liquids-rich natural gas opportunities, such as those found in the SCOOP, weareas that provide attractive rates of return.
Optimizing cash flows through operating efficiencies, cost reductions, and enhanced completions. We continue to believe crude oil valuations will be superior to natural gas valuationsmanage through the current commodity price downturn by focusing on improving operating efficiencies and reducing costs. Our key operating areas are characterized by large acreage positions in select unconventional resource plays with multiple stacked geologic formations that provide repeatable drilling opportunities and resource potential. We operate a relative Btu basis for the foreseeable future.

Growth Through Drilling. A substantial portionmajority of our annual capital expenditures are invested in drilling projectswells and leasehold acreage acquisitions. From January 1, 2008 through December 31, 2012, proved crude oil and natural gas reserve additions through extensions and discoveries were 649.0 MMBoe compared to 86.7 MMBoe of proved reserve acquisitions.

Internally Generated Prospects. Although we periodically evaluate and complete strategic acquisitions, our technical staff has internally generated a substantial portion ofbelieve the opportunities for the investmentconcentration of our capital. As an early entrant in new or emerging plays, we expect to acquire undeveloped acreage at a lower cost than later entrants into a developing play.

Focus on Unconventional Crude Oil and Natural Gas Resource Plays. Our experience with horizontal drilling, advanced fracture stimulation and enhanced recovery technologiesoperated assets allows us to commercially develop unconventional crude oilleverage our technical expertise and natural gas resource reservoirs, such asmanage the Red River B Dolomite, Bakken,development of our properties to achieve cost reductions through operating efficiencies and Oklahoma Woodford formations. Production rateseconomies of scale.

In 2015, we achieved large efficiency gains in the Red River unitsvarious aspects of our business, including reductions in spud-to-total depth drilling times and average days to drill horizontal laterals, which translated into substantial reductions in drilling costs in our core areas. Our drilling and completion costs for most operated wells declined on average approximately 25% in 2015 due to operational efficiency gains and lower service costs. In addition to lowering our drilling and completion costs, we also have been increasedoptimize cash flows through the use of enhanced recovery technologies including watercompletion technologies. In North Dakota, we are optimizing cash flows through enhanced completions using new hybrid and high pressure air injection. Ourslickwater designs, which have increased 90-day production rates between 35% and 50% on average. In Oklahoma, we are optimizing cash flows using enhanced completions that target optimum sand and fluid combinations. Initial results from the Red River units, the Bakken field,our 2015 activities are encouraging, and the Oklahoma Woodford play comprised approximately 33,831 MBoe, or 95%,we expect most of our total crude oil2016 well completions in Oklahoma will use enhanced completion methods.
Maintaining financial flexibility and natural gas production fora strong balance sheet. Maintaining a strong balance sheet and ample liquidity are key components of our business strategy. For 2016, we will continue our focus on preserving financial flexibility and ample liquidity as we manage the risks facing our industry. Our 2016 capital budget is reflective of decreased commodity prices and has been established based on an expectation of available cash flows, with any cash flow deficiencies expected to be funded by borrowings under our revolving credit facility. As we have done historically to preserve or enhance liquidity we may adjust our capital program throughout the year, endeddivest non-strategic assets, or enter into strategic joint ventures.
Focusing on organic growth through disciplined capital investments. Although we consider various growth opportunities, including property acquisitions, our primary focus is on organic growth through leasing and drilling in our core areas where we can best exploit our extensive inventory of repeatable drilling opportunities to achieve attractive rates of return. From January 1, 2011 through December 31, 2012.

Acquire Significant Acreage Positions in New or Developing Plays. In addition2015, our proved reserve additions through organic extensions and discoveries were 1,534 MMBoe compared to the 971,634 net undeveloped acres held in the Bakken play in North Dakota and Montana, the Oklahoma Woodford play, and the Niobrara play in Colorado and Wyoming, we held 375,412 net undeveloped acres in other crude oil and natural gas plays as86 MMBoe of December 31, 2012. Our technical staff is focused on identifying and testing new unconventional crude oil and natural gas resource plays where significant reserves could be developed if economically producible volumes can be achieved through advanced drilling, fracture stimulation and enhanced recovery techniques.proved reserve acquisitions during that same period.

Our Business Strengths

We have a number of strengths we believe willto help us successfullymanage through the current commodity price downturn and execute our business strategy:

strategy, including the following:

Large Acreage Inventory. We hold 1,347,046held approximately 1.19 million net undeveloped acres and 897,5421.15 million net developed acres under lease in certain premier U.S. resource plays as of December 31, 2012.2015. Approximately 72%59% of theour net undeveloped acres are located within unconventional resource plays in the Bakken, (North DakotaSCOOP, Northwest Cana, STACK and Montana),Arkoma Woodford (Oklahoma)areas. We have developed sizable acreage positions in our core operating areas and believe the Niobrara (Coloradoconcentration of our assets allows us to achieve operating efficiencies and Wyoming). The remaining balancereduce costs through economies of scale. We are among the largest leaseholders

in the Bakken and SCOOP plays with approximately 1.05 million net acres and 439,800 net acres under lease in those respective plays at December 31, 2015. Being an early entrant in the Bakken and SCOOP plays has allowed us to capture significant acreage positions in core parts of the net undeveloped acreage is located in conventional plays including 3D-defined locations for the Lodgepole (North Dakota), Morrow-Springer (Western Oklahoma) and Frio (South Texas) plays.

ExperienceExpertise with Horizontal Drilling and Enhanced RecoveryCompletion Methods. We have substantial experience with horizontal drilling and enhanced recovery methods. In 1992, we drilled our first horizontal well,completion methods and we have drilled over 1,800 horizontal wells since that time. We continue to be a leaderamong the industry leaders in the developmentuse of new drilling and completion technologies. Our trademarked ECO-PadWe continue to optimize drilling concept, which allows forand completion efficiencies through the use of multi-well pad drilling multiple wells from a single pad, is becoming a standard drilling approach in theour operating areas. Further, we are among industry because it improves land use and increases operating efficiencies. We started with drilling four wells per pad but have since begun drilling as many as 14 wells on a pad site. We are also on the leading edge ofleaders in extending lateral drilling lengths, in some instances uplengths. Results to three miles. In 2012, we completed the first multiple-unit spaced well drilled in Oklahoma, which had a horizontal section that was twice the length of previousdate indicate longer laterals in the area. Longer laterals are believed to have a positive impact on well productivity and economics. Additionally, we are pioneering the explorationWe have also been among industry leaders in testing enhanced completion technologies involving various combinations of fluid types, proppant types and evaluationvolumes, and stimulation stage lengths to determine optimal methods for maximizing crude oil recoveries and rates of the lower layers or “benches” of the Three Forks formationreturn. We continually refine our drilling and completion techniques in the Bakken field, initially targeting the first bench of the Three Forks in mid-2008 followed by the successful completion ofan effort to deliver improved results across our first well in the second bench in October 2011. In 2012, we successfully completed the first well ever drilled in the third bench of the Three Forks, the discovery of which may lead to an increase in recoverable reserves for the Company and the Bakken field as a whole.properties.

Control Operations Over a Substantial Portion of Our Assets and Investments. As of December 31, 2012,2015, we operated properties comprising 84%87% of our total proved reserves and 83% of our PV-10. By controlling a significant portion of our operations, we are able to more effectively manage the cost and timing of exploration and development of our properties, including the drilling and fracture stimulationcompletion methods used.

Experienced Management Team. Our senior management team has extensive expertise in the crude oil and natural gas industry. Our Chief Executive Officer, Harold G. Hamm, began his career in the crude oil and natural gas industry in 1967. Our 9 senior officers have an average of 2934 years of crude oil and natural gas industry experience.

Strong Financial Position and Liquidity. We have a revolving credit facility with lender commitments totaling $1.5$2.75 billion and a borrowing base of $3.25 billion as of February 15, 2013, with available borrowing capacity of $655.2 million at that date after considering outstanding borrowings and letters of credit. While our current commitments total $1.5 billion, we have the ability to increase the aggregate commitment levelwhich may be increased up to the lessera total of $2.5$4.0 billion or the borrowing base then in effectupon agreement with participating lenders to provide additional available liquidity if needed to maintain our growth strategy, take advantage of business opportunities and fund our capital program.program and commitments. We believehad approximately $1.9 billion of available borrowing capacity under our planned explorationcredit facility at February 19, 2016 after considering outstanding borrowings and development activitiesletters of credit. We have no near-term debt maturities, with our earliest maturity being a $500 million term loan due in November 2018.
Our credit facility is unsecured and does not have a borrowing base requirement that is subject to periodic redetermination based on changes in commodity prices and proved reserves. Additionally, downgrades or other negative rating actions with respect to our credit rating do not trigger a reduction in our current credit facility commitments, nor do such actions trigger a security requirement or change in covenants. Downgrades of our credit rating will, be funded substantially fromhowever, trigger increases in our operating cash flowscredit facility's interest rates and borrowingscommitment fees paid on unused borrowing availability under certain circumstances.
In November 2015, we completed transactions that increased our lender commitments under our revolving credit facility. Our 2013 capital expenditures budget has been established based on our current expectationfacility and refinanced a portion of available cash flows from operations and availability under our revolving credit facility. Should expected available cash flows from operations materially differ from expectations, we believe our credit facility has sufficient availabilityborrowings to fund any deficit or that we can reducean unsecured three-year term loan with a lower interest rate. These transactions enhanced our capital expenditures to be in line with cash flows from operations.

Crude Oil and Natural Gas Operations

Proved Reserves

Proved reserves are those quantities of crude oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates renewal is reasonably certain. TheIn connection with the estimation of proved reserves, the term “reasonable certainty” implies a high degree of confidence that the quantities of crude oil and/or natural gas actually recovered will equal or exceed the estimate. To achieve reasonable certainty, our internal reserve engineers and Ryder Scott Company, L.P (“Ryder Scott”), our independent reserve engineers, employed technologies that have been demonstrated to yield results with consistency and repeatability. The technologies and economic data used in the estimation of our proved reserves include, but are not limited to, well logs, geologic maps including isopach and structure maps, analogy and statistical analysis, and available downhole and production data, seismic data and well test data.

The following tables settable sets forth our estimated proved crude oil and natural gas reserves and PV-10 by reserve category as of December 31, 2012.2015. The total Standardized Measure of discounted cash flows as of December 31, 20122015 is also presented. Our reserve estimates as of December 31, 2015 are based primarily on a reserve report prepared by Ryder Scott. In preparing its report, Ryder Scott evaluated properties representing approximately 99% of our PV-10, 99% of our proved crude oil reserves, and 96%97% of our proved natural gas reserves as of December 31, 2012, and our2015. Our internal technical staff evaluated the remaining properties. A copy of Ryder Scott’s summary report is included as an exhibit to this Annual Report on Form 10-K.
Our estimated proved reserves and related future net revenues, PV-10 and PV-10Standardized Measure at December 31, 20122015 were determined using the 12-month unweighted arithmetic average of the first-day-of-the-month commodity prices for the period of January 20122015 through December 2012,2015, without giving effect to derivative transactions, and were held constant throughout the lives of the properties. These prices were $94.71$50.28 per Bbl for crude oil and $2.76$2.58 per MMBtu for natural gas ($86.5641.63 per Bbl for crude oil and $4.31$2.35 per Mcf for natural gas adjusted for location and quality differentials).

Revisions. Revisions of previous estimates. Revisions represent changes in previous reserve estimates, either upward or downward, resulting from new information normally obtained from development drilling and production history or resulting from a change in economic factors, such as commodity prices, operating costs, or development costs. Revisions
Commodity prices decreased significantly in 2015. The 12-month average price for crude oil decreased 47% from $94.99 per Bbl for 2014 to $50.28 per Bbl for 2015, while the year ended December 31, 201012-month average price for natural gas decreased 41% from $4.35 per MMBtu for 2014 to $2.58 per MMBtu for 2015. These decreases shortened the economic lives of certain producing properties and caused certain exploration and development projects to become uneconomic which had an adverse impact on our proved reserve estimates, resulting in downward reserve revisions of 185 MMBo and 391 Bcf (totaling 251 MMBoe) in 2015. We may experience additional downward reserve revisions as a result of prices in 2016 if the currently depressed price environment for crude oil and natural gas persists or worsens.
In response to the continued decrease in commodity prices throughout 2015, we have further refined our drilling program and reduced our planned rig count to concentrate our efforts in our core areas of North Dakota and Oklahoma that provide the best opportunities to improve recoveries and rates of return. The refinement of our drilling program contributed to the removal of PUD reserves no longer scheduled to be developed within five years from the date in which they were duefirst booked. One factor leading to better thanthe removal is an increased emphasis on multi-well pad drilling in the Bakken, which resulted in the removal of PUDs in certain areas in favor of PUDs more likely to be developed with pad drilling where operating efficiencies may be realized. Further, in the SCOOP play we removed certain PUD locations originally planned to be developed with standard lateral drilling lengths in favor of PUDs to be developed with extended length laterals in similar locations. Longer laterals are believed to have a positive impact on well productivity and economics. The combination of these and other factors resulted in

6



the removal of 65 MMBo and 197 Bcf (totaling 98 MMBoe) of PUD reserves in 2015. These removals do not necessarily represent the elimination of recoverable hydrocarbons physically in place. In some instances the removed reserves may be developed in the future in the event of a favorable change in commodity prices and an expansion of our capital expenditure budget.
Additionally, changes in anticipated production performance on certain properties resulted in 63 MMBo of downward revisions to crude oil proved reserves and higher average125 Bcf of upward revisions to natural gas proved reserves (netting to 42 MMBoe of downward revisions) in 2015.
The downward revisions described above were partially offset by upward revisions in 2015 due to lower operating costs being realized in conjunction with depressed commodity prices throughout 2010 compared to 2009.

and improvements in operating efficiencies as well as other factors.

Extensions, discoveries and other additions. These are additions to our proved reserves that result from (1)(i) extension of the proved acreage of previously discovered reservoirs through additional drilling in periods subsequent to discovery and (2)(ii) discovery of new fields with proved reserves or of new reservoirs of proved reserves in old fields. Extensions, discoveries and other additions for each of the three years reflected in the table above were primarily due to increases in proved reserves associated with our successful drilling activity and strong production growth in the Bakken field and SCOOP play. Proved reserve additions from our drilling activities in North Dakota. In 2012, we continued to make significant headwaythe Bakken totaled 96 MMBoe, 222 MMBoe and 276 MMBoe for 2015, 2014 and 2013, respectively, while reserve additions in developingSCOOP totaled 93 MMBoe, 208 MMBoe and expanding158 MMBoe for 2015, 2014 and 2013, respectively. Additionally, extensions and discoveries in 2015 were significantly impacted by successful drilling results in the Northwest Cana/STACK area, resulting in proved reserve additions of 57 MMBoe in 2015. See the subsequent section titled Summary of Crude Oil and Natural Gas Properties and Projects for a discussion of our North Dakota Bakken assets, both laterally and vertically, through

strategic exploration, planning and technology.2015 drilling activities. We expect a significant portion of future reserve additions will come from our major development projects in the Bakken, SCOOP, and Northwest Cana plays.

Sales of minerals in place. These are reductions to proved reserves that resultresulting from the disposition of properties during a period. During the year ended December 31, 2012, we disposed of certain non-strategic properties in Oklahoma, Wyoming, and our East region in an effort to redeploy capital to our strategic areas that we believe will deliver higher future growth potential. SeePart II, Item 8. Notes to Consolidated Financial Statements—Note 13.14. Property Acquisitions and Dispositions for further discussion of our 2012notable dispositions. We may continue to seek opportunities to sell non-strategic properties if and when we have the ability to dispose of such assets at favorable terms.

Purchases of minerals in place. These are additions to proved reserves that resultresulting from the acquisition of properties during a period.

Proved Undeveloped Reserves
All of our PUD reserves at December 31, 2015 are located in the Bakken, SCOOP, and Northwest Cana/STACK plays, our most active development areas, with those plays comprising 51%, 40%, and 9%, respectively, of our total PUD reserves at year-end 2015. The following table provides information regarding changes in our PUD reserves for the year ended December 31, 2015. Our PUD reserves at December 31, 2015 include 91 MMBoe of reserves associated with operated drilled but uncompleted wells.

Revisions of previous estimates. During the year ended December 31, 2015, we removed 1,225 gross (689 net) PUD locations, which resulted in the removal of 65 MMBo and 197 Bcf (totaling 98 MMBoe) of PUD reserves. These removals were due to the continued decrease in commodity prices during 2015, particularly in late 2015, and resulting refinement of our drilling program to place greater emphasis on core areas of the Bakken, SCOOP and Northwest Cana/STACK areas that provide the best opportunities to improve recoveries and rates of return, with increased focus on areas capable of being developed through the use of multi-well pad drilling and extended length laterals. These and other factors contributed to the removal of PUD

7



reserves in certain areas having less attractive rates of return, are less likely to be developed using pad drilling or extended laterals, or are otherwise no longer scheduled to be developed within five years of the date in which they were initially booked.
Also as a result of decreased commodity prices, certain exploration and development projects became uneconomic which had an adverse impact on our PUD reserve estimates, resulting in downward revisions of 131 MMBo and 301 Bcf (totaling 181 MMBoe) in 2015.
Additionally, changes in anticipated production performance on producing properties having offsetting PUD locations resulted in 46 MMBo of downward revisions to crude oil PUD reserves and 121 Bcf of upward revisions to natural gas PUD reserves (netting to 26 MMBoe of downward revisions) in 2015.
The downward revisions described above were partially offset by upward revisions in 2015 due to lower operating costs being realized on producing properties having offsetting PUD locations in conjunction with depressed commodity prices and improvements in operating efficiencies as well as other factors.
Extensions and discoveries. Extensions and discoveries were primarily due to increases in PUD reserves associated with our successful drilling activity in the Bakken, SCOOP and Northwest Cana/STACK areas. PUD reserve additions in the Bakken totaled 65 MMBo and 109 Bcf (totaling 83 MMBoe) in 2015, SCOOP PUD reserve additions totaled 28 MMBo and 248 Bcf (totaling 69 MMBoe), and Northwest Cana/STACK PUD reserve additions totaled 19 MMBo and 190 Bcf (totaling 50 MMBoe). See the subsequent section titled Summary of Crude Oil and Natural Gas Properties and Projects for a discussion of our 2015 drilling activities in these areas.
Conversion to proved developed reserves. In 2015, we developed approximately 18% of our PUD locations and 10% of our PUD reserves booked as of December 31, 2014 through the drilling of 526 gross (165 net) development wells at an aggregate capital cost of approximately $1.0 billion. In the second half of 2015, we accelerated the reduction of our capital spending and well completion activities in response to the continued decrease in commodity prices, which resulted in our 2015 capital spending being approximately $200 million below budget. These actions adversely impacted our conversion of PUD reserves to proved developed reserves during the year.
Development plans. We have acquired substantial leasehold positions in the Bakken, SCOOP and Northwest Cana/STACK plays. Our drilling programs to date in those areas have focused on proving our undeveloped leasehold acreage through strategic drilling, thereby increasing the amount of leasehold acreage in the secondary term of the lease with no further drilling obligations (i.e., categorized as held by production) and resulting in a reduced amount of leasehold acreage in the primary term of the lease. Going forward, while we may opportunistically drill strategic exploratory wells, the majority of our capital expenditures will be focused on developing our PUD locations given the current commodity price environment. Estimated future development costs relating to the development of PUD reserves are projected to be approximately $0.8 billion in 2016, $0.9 billion in 2017, $1.4 billion in 2018, $2.0 billion in 2019, and $1.4 billion in 2020. These capital expenditure projections are reflective of the significant decrease in commodity prices during the year and have been established based on an expectation of available cash flows and availability under our revolving credit facility. Development of our existing PUD reserves at December 31, 2015 is expected to occur within five years of the date of initial booking of the PUDs. PUD reserves not expected to be developed within five years of initial booking because of depressed commodity prices or for other reasons have been removed from our reserves at December 31, 2015. We had no PUD reserves at December 31, 2015 that remained undeveloped beyond five years from the date of initial booking.
Qualifications of Technical Persons and Internal Controls Over Reserves Estimation Process.
Ryder Scott, our independent reserves evaluation consulting firm, estimated, in accordance with generally accepted petroleum engineering and evaluation principles and definitions and guidelines established by the SEC, 99% of our PV-10, 99% of our proved crude oil reserves, and 96%97% of our proved natural gas reserves as of December 31, 20122015 included in this Annual Report on Form 10-K.

Proved Undeveloped Reserves. Reserve and PV-10 Sensitivities
Our year-end 2015 proved undeveloped reserves at December 31, 2012reserve and PV-10 estimates were 466,891 MBoe, consistingprepared using 2015 average prices of 334,293 MBbls of$50.28 per Bbl for crude oil and 795,585 MMcf of$2.58 per MMBtu for natural gas. In 2012, we developed approximately 17%Commodity prices existing in February 2016 are lower than the 2015 average prices. If commodity prices do not increase from current levels, our future calculations of ourestimated proved undeveloped reserves booked as of December 31, 2011 through the drilling of 231 gross (127.9 net) development wells at an aggregate capital cost of approximately $892 million. Also in

2012, we removed 202 gross (90.0 net) PUD locations,and PV-10 will be based on lower prices which resultedcould result in the removal of 3.5 MMBo and 183.8 Bcf (34.2 MMBoe) ofthen uneconomic reserves from our proved undeveloped reserves. These removals were predominantly due to our decision to declassify 100.4 Bcf (16.7 MMBoe) of proved undeveloped reserves in future periods.

Provided below are sensitivities illustrating the potential impact on our Arkoma Woodford district, which consists primarily of dryestimated proved reserves and PV-10 at December 31, 2015 under different pricing scenarios for crude oil and natural gas. For similar reasons, we removed 1.4 MMBoIn these sensitivities, all factors other than the commodity price assumption have been held constant for each well. These sensitivities are only meant to demonstrate the impact that changing commodity prices may have on estimated proved reserves and 73.3 Bcf (13.6 MMBoe) ofPV-10 and there is no assurance these outcomes will be realized.

The crude oil price sensitivities provided below show the impact on proved undeveloped reserves in our Northwest Cana district. Given current and projected prices forPV-10 under various crude oil price scenarios, with natural gas we elected to defer drillingprices being held constant at the 2015 average price of $2.58 per MMBtu.

The natural gas price sensitivities provided below show the impact on proved reserves and as a result declassified these proved undeveloped reserves accordingly. Estimated future development costs relating toPV-10 under various natural gas price scenarios, with crude oil prices being held constant at the development2015 average price of proved undeveloped reserves are projected to be approximately $1.8 billion in 2013, $2.2 billion in 2014, $2.0 billion in 2015, $1.4 billion in 2016, and $0.9 billion in 2017.

Since our entry into the Bakken field, we have acquired a substantial leasehold position. Our drilling programs to date have focused on proving our undeveloped leasehold acreage through strategic exploratory drilling, thereby increasing the amount of leasehold acreage in the secondary term of the lease with no further drilling obligations (i.e., categorized as held by production) and resulting in a reduced amount of leasehold acreage in the primary term of the lease with drilling obligations. While we will continue to drill strategic exploratory wells and build on our current leasehold position, we expect to increase our focus on developing our PUD locations. While full development of our current PUD inventory is expected to occur within five years, we believe additional PUD locations will be generated through drilling activities.

Summary of Crude Oil and Natural Gas Properties and Projects

Throughout

In the following discussion, we discussreview our budgeted number of wells and capital expenditures for 2013. Although we cannot provide any assurance, we believe2016 in our key operating areas. Our 2016 capital budget is reflective of the depressed commodity price environment and has been established based on an expectation of available cash flows. If cash flows from operations, remaining cash balance, andare materially impacted by a further decline in commodity prices, we have the ability to reduce our capital expenditures or utilize the availability of our revolving credit facility includingif needed to fund our ability to increase our borrowing capacity thereunder, will be sufficient to satisfy our 2013 capital budget. We may choose to access the capital markets for additional financing to take advantage of business opportunities that may arise if such financing can be arranged at favorable terms. The actual amount and timing of our capital expenditures may differ materially from our estimates as a result of, among other things, availableoperations. Conversely, higher cash flows unbudgeted acquisitions, actual drilling results, the availability of drilling rigs and other services and equipment, and regulatory, technological and competitive developments. Further, a decline in commodity prices could cause us to curtail our actual capital expenditures. Conversely,resulting from an increase in commodity prices could result in increased capital expenditures.

As referred to throughout this report, a “play” is a term applied to a portion of the exploration

The following table provides information regarding well counts and production cycle following the identification2016 budgeted capital expenditures by geologists and geophysicists of areas with potential crude oil and natural gas reserves. “Conventional plays” are areas believed to be capable of producing crude oil and natural gas occurring in discrete accumulations in structural and stratigraphic traps. “Unconventional plays” are areas believed to be capable of producing crude oil and natural gas occurring in accumulations that are regionally extensive, but require recently developed technologies to achieve profitability. Unconventional plays tend to have low permeability and may be closely associated with source rock as is the case with oil and gas shale, tight oil and gas sands and coalbed methane. Our operations in unconventional plays include operations in the Bakken and Woodford plays and the Red River units. Our operations within conventional plays include operations in the Lodgepole of North Dakota, Morrow-Springer of western Oklahoma and Frio in south Texas. In general, unconventional plays require the application of more advanced technology and higher drilling and completion costs to produce relative to conventional plays. These technologies can include hydraulic fracturing treatments, horizontal wellbores, multilateral wellbores, or some other technique or combination of techniques to expose more of the reservoir to the wellbore.

References throughout this report to “3D seismic” refer to seismic surveys of areas by means of an instrument which records the travel time of vibrations sent through the earth and the interpretation thereof. By recording the time interval between the source of the shock wave and the reflected or refracted shock waves from various formations, geophysicists are better able to define the underground configurations. “3D defined locations” are those locations that have been subjected to 3D seismic testing. We typically use 3D seismic testing to evaluate reservoir presence and/or continuity. We do not typically evaluate reservoir productivity using 3D seismic technology.

North Region

Our properties in the North region represented 90%63% of our PV-10 as of December 31, 20122015 and 78%66% of our average daily Boe production for the three months ended December 31, 2012. For the three months ended December 31, 2012, ourfourth quarter of 2015. Our average daily production from such properties was 83,205148,911 Boe per day for the fourth quarter of 2015, an increase of 45%3% over our average daily production for the three months ended December 31, 2011.comparable 2014 period. Our principal producing properties in the North region are located in the Bakken field and the Red River units.

Bakken Field

The Bakken field of North Dakota and Montana is one of the premier crude oil resource plays in the United States. It has been described byWe are a leading producer, leasehold owner and operator in the United States Geological Survey (“USGS”) asBakken. As of December 31, 2015, we controlled one of the largest continuous crude oil accumulation it has ever assessed. Estimates of recoverable reserves forleasehold positions in the Bakken field have grownwith approximately 1.71 million gross (1.05 million net) acres under lease.
Our total Bakken production averaged 136,355 Boe per day during the fourth quarter of 2015, up 4% from 4.3 billion barrels of crude oil, as publishedthe 2014 fourth quarter due to additional drilling and completion activity. Despite depressed commodity prices in a report issued by2015, we continued to make progress with our Bakken drilling program during the USGSyear which was almost entirely focused in April 2008, to potentially 11 billion barrels of crude oilNorth Dakota. Our 2015 drilling activity in North Dakota alone, as reported byfocused on the North Dakota Industrial Commission (“NDIC”)continued development of de-risked, higher rate-of-return areas in January 2011. In October 2011, the USGS began a study to update their 2008 assessment of recoverable reserves for the Bakken field to include reserves from the Three Forks formation and take into account improved well performance due to advances in drilling, completion and production technologies. Resultscore parts of the USGS study may be announced in late 2013.

Industry-wide production fromplay and the Bakken field reached a record 801,500 Boe per day in October 2012, up 55% over October 2011 based on data published by IHS Inc. Industry-wide drilling activity in the Bakken field also reached record levels at 229 rigs in June 2012. North Dakota now ranks as the second largesttesting of various enhanced completion technologies to determine optimal methods for maximizing crude oil producing state in the U.S. due to production growth in the Bakken field. We continue to be a leader in the developmentrecoveries and expansionrates of the Bakken field and control the largest leasehold position with approximately 1,725,089 gross (1,139,803 net) acres as of December 31, 2012. We are also the most active driller in the Bakken field, with 21 operated rigs drilling as of February 15, 2013. During 2012,return.

In 2015, we completed 573650 gross (204.1(181 net) wells in the Bakken. Our Bakken field. Our properties within the Bakken field represented 74%56% of our PV-10 as ofat December 31, 20122015 and 63%61% of our average daily Boe production for the three months ended December 31, 2012. As of December 31, 2012 we had completed 1,887 gross (757.7 net) wells in the Bakken field.2015 fourth quarter. Our inventory of proved undeveloped drilling locations in the Bakken field as of December 31, 2012 totaled 1,501 gross (847.3 net) wells.

During 2012, we saw our production, reserves and acreage position in the Bakken field grow while substantial portions of our undeveloped acreage continued to be de-risked due to the record levels of drilling activity in North Dakota. Our Bakken field production averaged 67,522 Boe per day during the three months ended December 31, 2012, up 64% from our average daily Bakken field production for the three months ended December 31, 2011. Our total proved Bakken field reserves at December 31, 2012 were 564 MMBoe, up 92% over our proved Bakken field reserves as of December 31, 2011.

Our development drilling activity accelerated in 2012 since much2015 were 663 MMBoe, which represents a decrease of the Bakken field is now entering the development mode. This allowed us23% compared to increase the use of our ECO-Pad technology in 2012. Using ECO-Pad technology allows us to utilize more efficient centralized production facilities that accelerate production and reduce the environmental footprint of our operations. Combined, we expect these efficiencies will result in reduced costs for wells drilled from ECO-Pads. Approximately 18% of our operated wells completed in 2012 were drilled from ECO-Pads. At February 15, 2013, 67% of our 21 operated rigs in the Bakken were capable of ECO-Pad drilling and 14 rigs were actively drilling pad locations.

We strengthened our Bakken focus in 2012 by executing strategic property acquisitions throughout the year, which allowed us to increase our ownership in existing and future operated and non-operated wells in the play. We believe the acquisitions will allow us to leverage the scale and efficiency of our Bakken operations to help lower our drilling and completion costs. As a result of our leasing and acquisition activities, we increased our net acreage position in the Bakken field by 24% during 2012, from 915,863 net acres as of December 31, 20112014 due in part to 1,139,803 net acres as of December 31, 2012. Approximately 51% of our net acreagedownward reserve revisions in the Bakken field is developed2015 prompted by lower commodity prices and the remaining 49% of our net acreage is undeveloped as of December 31, 2012.

We plan to invest approximately $2.4 billionchanges in drilling 558 gross (226.2 net) wells in the Bakken field during 2013, of which approximately 83% will be invested in North Dakota and the remaining 17% will be invested in Montana. We plan to average 22 rigs drilling in the Bakken field throughout the year, with 17 rigs located in North Dakota and 5 rigs in Montana.

North Dakota Bakken. Our production and reserve growth in the Bakken field during 2012 came primarily from our activities in North Dakota. Production increased to an average rate of 59,019 Boe per day during the three months ended December 31, 2012, up 66% from the average daily rate for the three months ended December 31, 2011. Proved reserves grew 102% year-over-year to 518 MMBoe as of December 31, 2012. As of December 31, 2012, our North Dakota Bakken properties represented 67% of our PV-10 and 55% of our average daily Boe production for the three months ended December 31, 2012. We completed 526 gross (173.0 net) wells during 2012, bringing our total number of wells drilled in the North Dakota Bakken to 1,589 gross (576.5 net) as of December 31, 2012. As of December 31, 2012, we had 1,378,784 gross (866,967 net) acres in the North Dakota Bakken field, of which 55% of the net acreage is developed and 45% of the net acreage is undeveloped.plans. Our inventory of proved undeveloped locations stood at 1,421totaled 1,292 gross (791.3(705 net) wells as of December 31, 2012.2015.

As of December 31, 2015, we operated eight

Our drilling activityrigs in the Bakken, all in North Dakota, which we subsequently decreased to four operated rigs in early 2016. We plan to average approximately fouroperated rigs in North Dakota Bakken field during 2012 was diversified, reflecting the extensive nature of our acreage position. With 866,967 net acresthroughout 2016. We plan to operate fewer rigs in the North Dakota Bakken in 2016 compared to 2015 as part of December 31, 2012, some areas of the field were under development while other areas were being tested through step-out and exploratory drilling. All combined,our efforts to align our 2016 capital expenditures with cash flows in 2012 we made significant progress in developing and expanding our North Dakota Bakken assets through strategic exploration, planning and technology.

During 2012, we expanded the known productive extents of the Bakken field laterally and vertically through strategic step-out and exploratory drilling. Our step-out drilling continued to expand the productive footprint of the field west and east of the Nesson anticline. Of particular significanceresponse to the Company and the Bakken fieldcontinued decrease in general during 2012 was our ongoing exploration efforts to evaluate the Lower Three Forks formation. Through our independent coring program, we discovered there were three additional layers or “benches” of crude oil bearing reservoir rockprices in the Lower Three Forks formation. We refer to these three benches as the second, thirdlate 2015 and fourth benches of the Three Forks formation (“TF2”, “TF3” and “TF4”, respectively) and they are located approximately 50 to 150 feet below the traditional Middle Bakken (“MB”) and Upper Three Forks (“TF1”) reservoirs. This discovery redefined the Bakken petroleum system and prompted the NDIC to expand the definition of the Bakken reservoir to include all zones from 50 feet above the top of the Bakken formation down to the base of the Three Forks formation across much of the Bakken field in North Dakota.

The discovery of three additional benches indicates the Lower Three Forks formation has the potential to add incremental reserves in the Bakken field. The existence of more reserves in place could potentially translate into an increase in recoverable reserves for the Company and the Bakken field as a whole. To determine if there are incremental reserves to be recovered from the Lower Three Forks formation, we have begun drilling wells to test the TF2, TF3 and TF4 reservoirs. early 2016.

In October 2011, we successfully completed our first well in the TF2. The Charlotte 2-22H was completed flowing 1,396 Boe per day from the TF2 and as of February 15, 2013 the well had produced 107 MBoe and continues to produce in line with a typical commercial TF1 producing well. In November 2012, we successfully completed the first well ever drilled in the TF3. The Charlotte 3-22H was completed flowing 953 Boe per day from the TF3 and as of February 15, 2013 had produced 33 MBoe and continues to produce in line with a typical commercial TF1 producing well. In 2013, we plan to drill 20 gross (15.2 net) strategically placed wells throughout our Bakken acreage to accelerate our assessment of the Lower Three Forks reservoirs.

During 2013,2016, we plan to invest approximately $2.0 billion drilling 507$320 million to drill, complete and initiate production on 127 gross (185.2(26 net) wells in the North Dakota Bakken field. Approximately 18% of the capital expenditures are expected to be spent on exploratoryBakken. Our 2016 drilling to test the lower benches of the Three Forks formation and conduct multi-zone pilot development projects. These pilot development projects will test the viability of developing four reservoirs (MB, TF1, TF2, and TF3) on 320-acre and 160-acre spacing. The remainder of the capital expenditures are expected to be spent on drilling development and step-out wells in the field. As of February 15, 2013, we had 16 operated rigs drilling in the North Dakota Bakken and plan to operate 17 rigs drilling in the play through most of 2013.

Montana Bakken. Our Montana Bakken properties are located primarily in the Elm Coulee field in Richland County, Montana. The Elm Coulee field was listed by the Energy Information Administration (“EIA”) in 2010 as the 17th largest onshore field in the lower 48 states of the United States ranked by 2009 proved liquid reserves. During 2012, we completed 47 gross (31.0 net) wells, bringing our total number of wells drilled in the Montana Bakken to 298 gross (181.2 net) wells as of December 31, 2012. Our production increased to an average rate of 8,503 Boe per day for the three months ended December 31, 2012, up 50% from the average daily rate for the three months ended December 31, 2011. As of December 31, 2012 our Montana Bakken properties represented 7% of our PV-10 and 8% of our average daily Boe production for the three months ended December 31, 2012. As of December 31, 2012, we owned 346,305 gross (272,836 net) acres in Montana Bakken, of which 39% of the net acreage is developed and the remaining 61% of the net acreage is undeveloped.

In 2012, we continued to expand the proven extents of the Elm Coulee field using state of the art drilling and completion technology. Areas once considered non-commercial based on old open hole completion technology

have now proven to be commercial using cased hole, multi-stage fracture stimulation technology. During 2012, our well completions in the immediate Elm Coulee field area included in-field, step-out and strategic exploratory wells that were completed flowing at initial 24 hour rates of up to 1,301 Boe per day. Based on our 2012 drilling program the productive limits of the Elm Coulee field were expanded up to approximately 10 miles to the north onto portions of our undeveloped leasehold.

We plan to invest approximately $426 million drilling 51 gross (41.0 net) wells in the Montana Bakken during 2013. Our drilling will focus on in-field development and continued expansiondrilling de-risked acreage in core parts of the Elm Coulee field onto ourplay that provide opportunities for converting undeveloped acreage northto acreage held by production, increasing capital efficiency, reducing finding and development costs, and maximizing rates of the field. As of February 15, 2013, we had 5 rigs drilling in the Montana Bakken and plan to maintain 5 rigs in the play through most of 2013. As of December 31, 2012, we had 80 gross (55.9 net) proved undeveloped locations identified in the Montana Bakken.

Red River Units

The Red River units are comprised of eightnine units located along the Cedar Creek Anticline in North Dakota, South Dakota and Montana that produce crude oil and natural gas from the Red River “B” formation, a thin continuous, dolomite formation at depths of 8,000 to 9,500 feet.formation. Our principal producing properties in the Red River units include the Cedar Hills units in North Dakota and Montana, the Medicine Pole Hills units in North Dakota, and the Buffalo Red River units in South Dakota. Our properties in the Red River units comprise a portion of the Cedar Hills field, which was listed by the EIA in 2010 as the 9th largest onshore field in the lower 48 states of the United States ranked by 2009 proved liquid reserves.

North Region Marketing Activities

Crude Oil.We are building uponutilize a portfolio approach (rail and pipe) to marketingmarket our crude oil that began in 2008 with our first shipments of crude oil by rail out of the Williston Basin. During 2012,Accessing new pipeline transportation optionality that came online in 2015, we accessed new market centers on the east and west coasts of the United States and expanded our marketing efforts along the U.S. gulf coast. This approach has provided flexibility to allow us to shift salesshifted a significant portion of our North region crude oil from rail transportation to pipeline transportation during the year. We plan to continue with a portfolio approach to reach the optimum markets that provide the most favorable pricing. During 2012, we moved from predominantly using pipelinesin an effort to delivermaximize wellhead value for our North region crude oil to traditional market centers in Guernsey, Wyoming and Clearbrook, Minnesota to using rail deliveries into U.S. coastal markets that yield superior pricing compared to the unstable mid-continent market centers.production.

Rail transportation costs are typically higher than pipeline transportation costs per barrel mile; however, the premium received for our North region production being sold at Brent-based prices in U.S. coastal markets compared to mid-continent West Texas Intermediate (“WTI”) benchmark pricing has more than offset the increased transportation costs. We expect that rail transportation will take a prominent role in crude oil deliveries out of the North region throughout 2013 and then may lessen in significance as additional pipeline infrastructure is built out of the Williston Basin to the great lakes, upper mid-west, southern mid-continent and gulf coast regions of the United States. We expect rail transportation costs will then be impacted by pressure to compete with pipeline economics.

We anticipate volatility in price differentials between the mid-continent and coastal markets will continue through 2013 as infrastructure is built out and refiners establish a desire for the high quality grade of Bakken crude oil. We believe the Bakken field contains superior quality crude oil with ample supply and volume growth to meet refiners’ needs for years to come.

Transportation infrastructure continues to improve in the North region with gathering systems picking up crude oil at well site storage tanks with subsequent delivery to railhead or regional pipeline terminals, thereby mitigating the need for truck deliveries. We expect more of our North region crude oil will be shipped in this fashion through the coming years, especially as we accelerate development drilling using ECO-Pad technology.

Natural Gas. Field infrastructure build-out continued at a rapid pace in the Williston Basin in 20122015 as third party midstream gathering and processing companies expanded field gathering and compression facilities, cryogenic processing capacity and natural gas liquids (“NGL”) pipeline and rail capacity to market centers. Aided by improved infrastructure,In 2015, we reducedcontinued to be a leader in minimizing natural gas flaring in North Dakota. For the percentageyear ended December 31, 2015, we delivered approximately 87% of our operated natural gas production being flared in North Dakota Bakken to market, flaring approximately 13% compared to an average of 18% flared by approximately 50%industry peers operating in 2012. During December 2012, we flared approximately 10% of produced natural gas volumes on our operated North Dakota Bakken wells and expect to further reduce this amount as we continue to build out infrastructure and transition to a greater use of ECO-Pad development in 2013 and beyond.the play.

South Region

Our properties in the South region represented 10%37% of our PV-10 as of December 31, 20122015 and 21%34% of our average daily Boe production for the three months ended December 31, 2012.fourth quarter of 2015. For the three months ended December 31, 2012,2015 fourth quarter, our average daily production from such properties was 22,62076,025 Boe per day, up 36%an increase of 56% from the samecomparable period in 2011. Our principal producing properties in this region are located in the Anadarko and Arkoma basins of Oklahoma, as well as various basins in Texas and Louisiana.

Oklahoma Woodford Shale

The Oklahoma Woodford is a widespread unconventional shale reservoir that produces crude oil, natural gas and natural gas condensate in various basins across the state of Oklahoma.2014. Our principal producing properties in the Oklahoma WoodfordSouth region are located in the AnadarkoSCOOP, Northwest Cana and Arkoma basins. Combined, these propertiesSTACK areas of Oklahoma.

SCOOP
The SCOOP play currently extends across Garvin, Grady, Stephens, Carter, McClain and Love Counties in Oklahoma and contains crude oil and condensate-rich fairways as delineated by numerous industry wells. Our SCOOP leasehold has the potential to contain hydrocarbons from a variety of conventional and unconventional reservoirs overlying and underlying the Woodford formation in Oklahoma. In 2014, our drilling activities resulted in the vertical expansion of our SCOOP position and discovery of the Springer formation, which is located approximately 1,000 to 1,500 feet above the Woodford formation. Located in the heart of our SCOOP acreage, our Springer position supplements our Woodford leasehold and expands our resource potential and inventory in the play. Our 2015 drilling activity in SCOOP focused on expanding the known productive extents of the SCOOP Woodford and SCOOP Springer formations and continued development of de-risked, higher rate-of-return areas in core parts of the play. Also, in 2015 we began operation of water recycling facilities in the SCOOP area that economically reuse stimulation water for both operational efficiencies and environmental benefits.
We are a leading producer, leasehold owner and operator in the SCOOP play. As of December 31, 2015, we controlled one of the largest leasehold positions in SCOOP with approximately 771,300 gross (439,800 net) acres under lease. SCOOP represented 9%31% of our PV-10 as of December 31, 20122015 and 19%29% of our average daily Boe production for the three months ended December 31, 2012. Production from the Oklahoma Woodford for 2012 totaled 7,099 MBoe, up 100% over 2011. Average daily production for our Oklahoma Woodford properties for the three months ended December 31, 2012 was 20,064 Boe per day, up 49% over our average daily production for the three months ended December 31, 2011. Asfourth quarter of December 31, 2012, we held 804,025 gross (428,192 net) acres in the Oklahoma Woodford. As of December 2012, 28% of the net acreage is developed and the remaining 72% of the net acreage is undeveloped.

During 2012, we completed 93 gross (48.7 net) Oklahoma Woodford wells. During 2013, we plan to invest approximately $455 million drilling 92 gross (41.9 net) wells in the Oklahoma Woodford. As of February 15, 2013 we had 6 rigs drilling in the Oklahoma Woodford and plan to operate an average of 9 rigs in the play through most of 2013.

In 2012, we divided our Anadarko Woodford assets into two projects we refer to as SCOOP and Northwest Cana. Our wells in the SCOOP area typically produce significantly more crude oil and natural gas liquids than wells in Northwest Cana and provide a higher rate of return on the dollars we invest. Consequently, our drilling and development plans for SCOOP differ from our plans for Northwest Cana. As a result, we now report and discuss the two areas separately. The difference between the SCOOP and Northwest Cana areas is rooted in our geologic model that determined the SCOOP area is ideally suited for crude oil and liquids rich production from the Woodford reservoir. Due to the depositional, tectonic and thermal history of the SCOOP area, we believe it contains some of the best and thickest Woodford reservoir rocks in Oklahoma. The Woodford formation is

thought to be the source of much of the crude oil produced from over 60 different conventional reservoirs in Oklahoma since the early 1900s. Three of the largest crude oil producing counties in Oklahoma are located in the SCOOP play.

SCOOP

Our SCOOP properties are located in southern Oklahoma primarily in Garvin, Grady, Stephens, Carter, McClain and Love Counties. SCOOP represented 7% of our PV-10 as of December 31, 2012 and 7% of our average daily Boe production for the three months ended December 31, 2012.2015. For the year ended December 31, 2012,2015, SCOOP production grew 297%75% over 20112014 due to the continued success of our drilling activity in the play. We completed 204 gross (74 net) wells in SCOOP during 2015. Proved reserves increased drilling activity. For the three months ended December 31, 2012, SCOOP production averaged 7,123 Boe per day, up 281% over our average daily production for the three months ended December 31, 2011. As12% year-over-year to 413 MMBoe as of December 31, 2012 we held 412,816 gross (218,167 net) acres under lease in SCOOP. As2015, of December 31, 2012, 10% of the net acreage iswhich 32% represents proved developed and the remaining 90% of the net acreage is undeveloped.reserves. Our inventory of proved undeveloped drilling locations in SCOOP as of December 31, 20122015 totaled 122370 gross (58.4(224 net) wells.

We completed 47 gross (24.8 net) wells in SCOOP during 2012 and as of December 31, 2012 we had completed a total of 68 gross (37.2 net) wells in SCOOP. Although SCOOP is in the early stages of development, industry-wide drilling results through December 31, 2012 have established a crude oil producing fairway and a condensate rich, natural gas producing fairway that combined is approximately 15 to 20 miles wide and 120 miles long. Our internal reserve models estimate wells in the SCOOP crude oil fairway may produce approximately 626 MBoe per well and wells in the SCOOP’s condensate rich natural gas fairway may produce approximately 1,190 MBoe per well. The SCOOP area could prove to be another significant opportunity for reserve and production growth for the Company.

A possible upside to SCOOP is the potential to encounter additional pay from a variety of conventional and potential unconventional reservoirs overlying and underlying the Woodford formation. There are over 60 different conventional reservoirs known to produce in the SCOOP area. These conventional reservoirs have the potential to produce locally under our SCOOP acreage.

In 2013,2016, we plan to invest approximately $450$260 million to drill, 90complete and initiate production on 113 gross (40.5(25 net) wells in the SCOOP play. We also expectOur 2016 drilling program will continue to invest approximately $9 millionfocus on expanding the known productive extents of the SCOOP Woodford and SCOOP Springer formations and de-risking our acreage, while focusing on areas that provide opportunities for converting undeveloped acreage to acquire 103 square milesacreage held by production, increasing capital efficiency, reducing finding and development costs, and maximizing rates of additional proprietary 3D seismic data to guide future drilling.return. As of February 15, 2013,December 31, 2015, we had 6six operated rigs drilling in the SCOOP. WeSCOOP play and plan to addaverage approximately five to six operated rigs throughout the year targeting 12 rigs by December 2013 with an expected average rig count of 9 for 2013.

2016.

Northwest Cana

and STACK

Our Northwest Cana properties are located in northwestern Oklahoma primarily in Blaine, Dewey and Custer Counties.Counties of Oklahoma and primarily target the Woodford formation. In September 2014, we entered into an agreement with a U.S. subsidiary of SK E&S Co. Ltd (“SK”) of South Korea to jointly develop a significant portion of our Northwest Cana natural gas properties, primarily in Blaine and Dewey counties. Under the agreement, SK has committed to fund, or carry, 50% of our share of certain future drilling and completion costs through September 2019, which has enabled us to generate favorable economics and value from previously idle properties in Northwest Cana. As of December 31, 2015, we had five operated rigs drilling in Northwest Cana and plan to average approximately five operated rigs throughout 2016 to capitalize on the favorable economics provided by our joint development agreement with SK. In 2016, we plan to invest approximately $62 million to drill, complete and initiate production on 28 gross (11 net) wells in Northwest Cana within the area of mutual interest with SK.
In 2015, we added the STACK play to our portfolio of assets through our leasing and drilling efforts. STACK, an acronym for Sooner Trend Anadarko Canadian Kingfisher, is a significant new resource play located in the Anadarko Basin of Oklahoma characterized by stacked geologic formations with major targets in the Meramec and Osage formations overlying the Woodford formation. A significant portion of our STACK acreage is located in over-pressured portions of Blaine, Dewey and Custer Counties of Oklahoma where we believe the reservoirs are typically thicker and deliver superior production rates relative to normal-pressured areas of the STACK petroleum system. Our drilling in STACK is in the early stages and production has just recently begun to grow. We anticipate the economics from our STACK properties will compare favorably with our SCOOP and North Dakota Bakken assets and will provide value-added opportunities for the Company. As of December 31, 2015, we had fouroperated rigs drilling in STACK and we plan to average approximately four to five operated rigs throughout 2016. In 2016, we plan to invest approximately $142 million to drill, complete and initiate production on 15 gross (9 net) wells in STACK. Our 2016 activities will be focused on delineating and de-risking our acreage, monitoring production, and further developing our geologic and economic models in the area.
Combined, our Northwest Cana and STACK properties represented 2%5% of our PV-10 as of December 31, 2012 and 9% of our average daily Boe production for the three months ended December 31, 2012. For the year ended December 31, 2012, Northwest Cana production grew 134% over 2011 due to our increased drilling activity. For the three months ended December 31, 2012, Northwest Cana production averaged 9,716 Boe per day, up 22% over our average daily production for the three months ended December 31, 2011. As of December 31, 2012 we held 271,743 gross (178,432 net) acres under lease in Northwest Cana. As of December 31, 2012, 40% of the net acreage is developed and the remaining 60% of the net acreage is undeveloped. During 2012, we completed 43 gross (22.8 net) wells in Northwest Cana and as of December 31, 2012 we had completed a total of 161 gross (73.3 net) wells in Northwest Cana. We had a total of 90 gross (38.6 net) proved undeveloped locations on our Northwest Cana acreage as of December 31, 2012. No significant drilling or development plans are expected to take place in the Northwest Cana play in 2013 due to the pricing environment for natural gas.

Arkoma Woodford

The Arkoma Woodford represented less than 1% of our PV-10 as of December 31, 20122015 and 3% of our average daily Boe production for the three months ended December 31, 2012. Year-over-year, Arkoma Woodford production decreased 2% due to the suspensionfourth quarter of our drilling program in 2012 due to the pricing environment for natural gas. In 2012, we completed 3 gross (1.1 net) wells, compared to 18 gross (4.8 net) wells in 2011.2015. As of December 31, 20122015, we had completedheld a total of 395 gross (59.6 net) wells in the Arkoma Woodford play. As of December 31, 2012, we held 119,466 gross (31,593 net)155,221 net acres under lease in Northwest Cana and STACK, representing acreage available for drilling in the Arkoma Woodford play. Approximately 83% of our net acreage is developedformation (Northwest Cana) and the remaining 17%Meramec and Osage formations (STACK) overlying the Woodford and inclusive of 38,600 total net acres of Woodford drilling rights in the area of mutual interest established under our net acreage is undevelopedNorthwest Cana joint development agreement with SK.

Combined production in Northwest Cana and STACK increased to an average rate of 7,709 Boe per day during the fourth quarter of 2015, up 104% over the 2014 fourth quarter due to additional drilling and completion activity resulting from our drilling program. We completed a combined 26 gross (10 net) wells in Northwest Cana and STACK during 2015. Proved reserves totaled 84 MMBoe as of December 31, 2012. We had a total2015, of 22 gross (15.2 net)which 25% represents proved developed reserves. Our combined inventory of proved undeveloped locations in the Arkoma Woodfordstood at 198 gross (66 net) wells as of December 31, 2012. In 2013, we do not plan on drilling any new wells in the play.

South Region Marketing Activities

Crude Oil.Due to the proximity of our Our South region operationsproduction is located in relatively close proximity to regional refineries as well as the market centercrude oil trading hub located in Cushing, Oklahoma,Oklahoma. Because of this close proximity to local markets as well as Cushing, we typically sellare able to market our South region production directly to midstream trading and transportation companies atwith the wellhead with price realizations that correlate with WTI benchmark pricing. We anticipate continuing this approach through early 2013 and to begin deliveryintent of production from our SCOOP properties via wellhead pipeline gathering systems directly into Cushing as field infrastructure is constructed and developed.

During 2013, we expectcapturing the disparity of WTI pricing to Brent pricing will begin to improve asbest market prices available depending on the recently expanded Seaway Pipeline begins to alleviate the oversupply of crude oil at Cushinggrade and as Permian Basin production beginslocation. We use the competition among refineries, midstream companies, and bulk traders in an effort to take newly-developed routes to gulf coast market centers that do not go to or through Cushing.

maximize wellhead value for our crude oil production.

Natural Gas. In 2012,2015, field infrastructure build-out continued at a rapid pace in the Anadarko Basin and in SCOOP as third party midstream gathering and processing companies expanded field gathering and compression facilities, cryogenic processing capacity and NGL pipeline capacity to market centers. On January 1, 2016 a third party placed a new lateral into service that connects to an existing plant which provides a connection to an interstate pipeline system for sales to downstream customers.
Throughout our South region leasehold, we are coordinating our well completion operations to coincide with well connections to gathering systems in order to minimize greenhouse gas emissions.

We continue to assess downstream transportation options

Title to Properties

As is customary in the crude oil and natural gas industry, upon initiation of leasing fee mineral interests on undeveloped lands which do not have associated proved reserves, contract landmen conduct a title examination of courthouse records upon acquisition of undeveloped leaseholds which do not have proved reserves.to determine fee mineral ownership. Such title examinations are reviewed and approved by Company landmen. Upon entering into a purchase and sale agreement for an acquisition from a third party, whether lands are producing crude oil and natural gas leases or non-producing, Company and contract landmen perform title examinations at applicable courthouses and examine the seller's internal land, legal, well, marketing and accounting records including existing title opinions. We may also procure an acquisition title opinion from outside legal counsel on higher value properties.
Prior to the commencement of drilling operations, on those properties, we procure aan original title opinion, or supplement an existing title opinion, from externaloutside legal counsel and perform curative work necessary to satisfy requirements pertaining to material title defects.defects, if any. We generally will not commence drilling operations on a

property until we have cured material title defects on such property. as to the Company's interest.

We have procured title opinions and cured material defects as to Company interests on substantially all of our producing properties and believe we have defensible title to our producing properties in accordance with standards generally accepted in the crude oil and natural gas industry. Prior to completing an acquisition of producing crude oil and natural gas leases, Company and contract landmen perform title examinations at applicable courthouses and examine the seller’s internal land/legal records including existing title opinions. We may procure a title opinion depending on the materiality of the properties involved. Our crude oil and natural gas properties are subject to customary royalty and other interests, liens to secure borrowings under our revolving credit facility, and otherleasehold burdens which we believe do not materially interfere with the use of the properties or affect our carrying value of such properties.

Marketing and Major Customers

Most of our crude oil production is sold to end userscrude oil refining companies at major market centers. Other production not sold at major market centers is sold to select midstream marketing companies or crude oil refining companies at the lease. We have significant production directly connected to pipeline gathering systems, with the remaining balance of our production being transported by truck or rail. Where directly marketed crude oil is transported by truck, it is delivered to the most practicala point on a connected pipeline system for delivery to a sales point “downstream” on another connecting pipeline. CrudeWhen crude oil is sold at the lease is delivered directly onto the purchaser’s truck and the sale is complete at that point.

As a result

The majority of pipeline constraints, the continuous increase in Williston Basin production, and our desire to transport our crude oil to coastal markets which currently provide the most favorable pricing, in December 2012 we transported approximately 72% of our operated crude oil production from the Bakken field by rail. We are using both manifest and unit train facilities for these shipments and anticipate these shipments will continue.

We have a strategic mix of gas transport, processing and sales arrangements for our natural gas production. Our natural gas production is sold at various points along the market chain from wellheadour lease locations to points downstreammidstream purchasers under monthly interruptible packaged-volume deals, short-term seasonal packages, and long-termterm contracts. These contracts include multi-year term agreements with acreage dedication type contracts. All of our natural gas is sold at market.dedication. Some of our contracts allow us the flexibility to sellaccept, as partial payment for our sale of gas in the field, an “in-kind” volume of processed gas at the well or,tailgate of the midstream purchaser’s processing plant. When we elect to do so, we transport this processed gas to a downstream market where it is sold. Sales at these downstream markets are mostly under monthly interruptible packaged volume deals, short term seasonal packages, and long term multi-year contracts. We continue to develop relationships and have potential future contracts with notice, take our gas “in-kind”, transport, process,end-use customers, including utilities, industrial users, and sell in the market area. Midstreamliquefied natural gas gathering and processing companies areexporters, for sale of gas we elect to take in-kind in lieu of cash for our primary transporters and purchasers.

leasehold sales.

Our marketing of crude oil and natural gas can be affected by factors beyond our control, the effects of which cannot be accurately predicted. For a description of some of these factors, seePart I, Item 1A. Risk factors—Our business depends on crude oil and natural gas transportation, processing and refining facilities, most of which are owned by third parties, and on the availability of rail transportation.

No other purchasers accounted for more than 10% of our total crude oil and natural gas revenues for 2012, 2011 and 2010.2015. We believe the loss of our largestany single purchaser would not have a material adverse effect on our operations, as crude oil and natural gas are fungible products with well-established markets and numerous purchasers in our producingvarious regions.

Competition

We operate in a highly competitive environment for acquiring properties, marketing crude oil and natural gas and securing trained personnel. Also, there is substantial competition for capital available for investment in the crude oil and natural gas industry. Our competitors vary within the regions in which we operate, and some of our competitors may possess and employ financial, technical and personnel resources greater than ours, which can be particularly important in the areas in which we operate. Those companies may be able to pay more for productive crude oil and natural gas properties and exploratory prospects and to evaluate, bid for and purchase a greater number of properties and prospects than our financial or personnel resources permit. In addition, shortages or the

high cost of drilling rigs, equipment or other services could delay or adversely affect our development and exploration operations. Our ability to acquire additional prospects and to find and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate transactions economically in a highly competitive environment.

In addition, as a result of the significant decrease in commodity prices, the number of providers of materials and services has decreased in the regions where we operate. As a result, the likelihood of experiencing competition and shortages of materials and services may be increased in connection with any period of commodity price recovery.

Regulation of the Crude Oil and Natural Gas Industry

All of our

Our operations are conducted onshore almost entirely in the United States. The crude oil and natural gas industry in the United States is subject to various types of regulation at the federal, state and local levels. Laws, rules, regulations, policies, and interpretations affecting the crude oil and natural gasour industry have been and are pervasive and are continuously reviewed by legislators and regulators, includingresulting in the imposition of new or increased requirements on us and other industry participants. Applicable laws and regulations and other requirements affecting our industry and its members often carry substantial penalties for failure to comply. SuchThese requirements may have a significant effect on the exploration, development, production and sale of crude oil and natural gas. These requirementsgas and increase the cost of doing business and consequently, affect profitability. We believe we are in substantial compliance with all laws and regulations and policies currently applicable to our operations and our continued compliance with existing requirements will not have a material adverse impact on us. However,In addition, because public policy changes affecting the crude oil and natural gas industry are commonplace and because laws, rules and regulations may be enacted, amended or reinterpreted, we are unable to predict the future cost or impact of complying with such laws, rules and regulations. We do not expect any future legislative or regulatory initiatives will affect our operationsus in a manner materially different than they would affect our similarly situated competitors.

Following

The following is a discussion of significant laws, rules and regulations that may affect us in the areas in which we operate.

Regulation of Salessales and Transportationtransportation of Crude Oilcrude oil and Natural Gas Liquids

natural gas liquids

Sales of crude oil and natural gas liquids or condensate in the United States are not currently regulatedsubject to price controls and are made at negotiated prices. Nevertheless, the U.S. Congress could enact price controls in the future. TheSince the 1970s, the United States does regulatehas regulated the exportation of petroleum and petroleum products, and these regulations could restrictwhich restricted the markets for these commodities and thus affectaffected sales prices. However, in December 2015, the U.S. Congress passed a legislative bill eliminating the export restrictions.
With regard to our physical sales of crude oil and any derivative instruments relating to crude oil, we are required to comply with anti-market manipulation laws and related regulations enforced by the Federal Trade Commission (“FTC”) and the Commodity Futures Trading Commission (“CFTC”). See the discussion below of “Other Federal Laws and Regulations Affecting Our Industry.Industry—FTC and CFTC Market Manipulation Rules.ShouldIf we violate the anti-market manipulation laws and regulations, we could be subject to substantial penalties and related third-party damage claims by, among others, sellers, royalty owners and taxing authorities.

Our sales of crude oil are affected by the availability, terms and costs of transportation. The transportation of crude oil and NGLs, as well as other liquid products, is subject to rate and access regulation. The Federal Energy Regulatory Commission (“FERC”) regulates interstate crude oil and NGL pipeline transportation rates under the Interstate Commerce Act and the Energy Policy Act of 1992.1992 and the rules and regulations promulgated under those laws. In general, such pipeline rates must be just and reasonable and must not be unduly discriminatory or confer any undue preference upon any shipper. Oil and other liquid pipeline rates are often cost-based, although many pipeline charges today are based on historical rates adjusted for inflation and other factors, and other charges may result from settlement rates agreed to by all shippers or market-based rates, which are permitted in certain circumstances. FERC or interested persons may challenge existing or changed rates or services. Intrastate crude oil and NGL pipeline transportation rates may be subject to regulation by state regulatory commissions. The basis for intrastate pipeline regulation, and the degree of regulatory oversight and scrutiny given to intrastate crude oil pipeline rates, varies from state to state. Insofar as the interstate and intrastate transportation rates we pay are generally applicable to all comparable shippers, we believe the regulation of intrastate transportation rates will not affect our operationsus in a way that materially differs from the effect on the operations of our competitors who are similarly situated.

situated competitors.

Further, interstate pipelines and intrastate common carrier pipelines must provide service on an equitable basis. Under this standard, such pipelines must offer service to all similarly situated shippers requesting service on the

same terms and under the same rates. When such pipelines operate at full capacity, access is governed by prorating provisions, which may be set forth in the pipelines’ published tariffs. We believe we generally will have access to crude oil pipeline transportation services to the same extent as our similarly situated competitors.

We transport a portion of the operated crude oil production from our North region to market centers using rail transportation facilities owned and operated by third parties, with approximately 17% of such production being shipped by rail in December 2015. The U.S. Department of Transportation’s (“U.S. DOT”) Pipeline and Hazardous Materials Safety Administration (“PHMSA”) establishes safety regulations relating to crude-by-rail transportation. Third party rail operators are subject to the regulatory jurisdiction of the Surface Transportation Board of the U.S. DOT, the Federal Railroad Administration (“FRA”) of the U.S. DOT, the Occupational Safety and Health Administration, as well as other federal regulatory agencies. Additionally, various state and local agencies have jurisdiction over disposal of hazardous waste and seek to regulate movement of hazardous materials if not preempted by federal law.

In 2008, the U.S. Congress passed the Rail Safety and Improvement Act, which implemented regulations governing different areas related to railroad safety. More recently, the FRA and PHMSA have undertaken several actions to enhance the safe transport of crude oil, including but not limited to: issuing an order requiring proper testing, classification and handling of crude oil as a hazardous material; requiring expanded hazardous material route planning for railroads to avoid populated and other sensitive areas; issuing safety advisories, alerts, emergency orders and regulatory updates; conducting special unannounced inspections; moving forward with rulemaking to enhance tank car standards for certain trains carrying crude oil and ethanol; and reaching agreement with the railroad industry on a series of voluntary actions it can take to improve safety. Notably, in May 2014 the U.S. DOT issued an order requiring all railroads operating trains containing large amounts of Bakken crude oil to notify state emergency response commissions about the operation of such trains through their states. The order requires each railroad operating trains containing more than 1,000,000 gallons of Bakken crude oil, or approximately 35 tank cars, in a particular state to provide the state with notification regarding the volumes of Bakken crude oil being transported, frequencies of anticipated train traffic and the route through which Bakken crude oil will be transported.  Also in May 2014, the FRA and PHMSA issued a safety advisory to the rail industry strongly recommending the use of tank cars with the highest level of integrity in their fleet when transporting Bakken crude oil. In May 2015, PHMSA issued a final rule which requires, among other things, enhanced tank car standards for new and existing tank cars, a classification and testing program for crude oil, and a requirement that older DOT-111 tank cars be retrofitted to comply with new tank car design standards in accordance with a specified timeline beginning in May 2017.

We do not currently own or operate rail transportation facilities or rail cars; however, regulations that impact the testing or rail transportation of crude oil could increase our costs of doing business and limit our ability to transport and sell our crude oil at market centers throughout the United States, which could have a material adverse effect on our financial condition, results of operations and cash flows. We are unable to estimate the potential impact on our business associated with new federal or state rail transportation regulations; however, we do not expect such regulations will affect us in a materially different way than similarly situated competitors.
At the state level, in December 2014 the North Dakota Industrial Commission ("NDIC") introduced new rules designed to reduce the potential flammability of crude oil produced from the Bakken petroleum system (the Bakken, Three Forks, and Sanish Pool formations) before it is loaded on railcars and transported. The rules, which became effective in April 2015, outline a series of standards for pressure and temperature for production facilities to follow in order to separate certain liquids and gases from the crude oil prior to transport. The regulations are designed to leave the crude oil with a vapor pressure of no more than 13.7 pounds per square inch ("psi") compared to national standards that require 14.7 psi. While the new rules could increase the cost of doing business in North Dakota, we do not expect these changes to have a material impact on us nor will they affect us in a way that materially differs from our similarly situated competitors.
Regulation of Salessales and Transportationtransportation of Natural Gas

natural gas

In 1989, the U.S. Congress enacted the Natural Gas Wellhead Decontrol Act, which removed all remaining price and non-price controls affecting wellhead sales of natural gas. The FERC, which has the authority under the Natural Gas Act (“NGA”) to regulate prices, terms, and conditions for the sale of natural gas for resale in interstate commerce, has issued blanket authorizations for all gas resellers subject to FERC regulation, except interstate pipelines, to resell natural gas at market prices. However, either the U.S. Congress or the FERC (with respect to the resale of gas in interstate commerce) could re-impose price controls in the future. The U.S. Department of Energy (“U.S. DOE”) regulates the terms and conditions for the exportation and importation of natural gas (including liquefied natural gas or “LNG”). U.S. law provides for very limited regulation of exports to and imports from any country that has entered into a Free Trade Agreement (“FTA”) with the United States that provides for national treatment of trade in natural gas; however, the U.S. DOE’s regulation of imports and exports from and to countries without such FTAs is more comprehensive. The FERC also regulates the construction and operation of import and export facilities, including LNG terminals. Regulation of imports and exports and related facilities may materially affect natural gas markets and sales prices.

The FERC regulates interstate natural gas transportation rates and service conditions under the NGA and the Natural Gas Policy Act of 1978 (“NGPA”), which affects the marketing of natural gas we produce, as well as revenues we receive for sales of our natural gas. The FERC has endeavored to make natural gas transportation more accessible to natural gas buyers and sellers on an open and non-discriminatory basis. The FERC has stated that open access policies are necessary to improve the competitive structure of the natural gas pipeline industry and to create a regulatory framework that willto put natural gas sellers into more direct contractual relations with natural gas buyers by, among other things, unbundling the sale of natural gas from the sale of transportation and storage services. The FERC has issued a series of orders to implement its open access policies. As a result, the interstate pipelines’ traditional role as wholesalers of natural gas has been eliminated and replaced by a structure under which pipelines provide transportation and storage services on an open access basis to others who buy and sell natural gas. Although the FERC’s orders do not directly regulate natural gas producers, they are intended to foster increased competition within all phases of the natural gas industry. We cannot provide any assurance that the pro-competitive regulatory

19



approach established by the FERC will continue. However, we do not believe any action taken will affect us in a materially different way than othersimilarly situated natural gas producers.

With regard to our physical sales of natural gas and any derivative instruments relating to natural gas, we are required to observe anti-market manipulation laws and related regulations enforced by the FERC and the CFTC. See the discussion below of “Other Federal Laws and Regulations Affecting Our Industry.Industry—FTC and CFTC Market Manipulation Rules.ShouldIf we violate the anti-market manipulation laws and regulations, we could be subject to substantial penalties and related third-party damage claims by, among others, sellers, royalty owners and taxing authorities. In addition, pursuant to various FERC orders, we may be required to submit reports to the FERC for some of our operations. See the discussion below of “Other Federal Laws and Regulations Affecting Our Industry—FERC Market Transparency and Reporting Rules.”

Gathering service, which occurs upstream of jurisdictional transmission services, is generally regulated by the states onshore and in state waters. Although its policies on gathering systems have varied in the past, the FERC has reclassified certain jurisdictional transmission facilities as non-jurisdictional gathering facilities, which has the tendency to increase our costs of getting natural gas to point of sale locations. State regulation of natural gas gathering facilities generally includes various safety, environmental, and in some circumstances, equitable take requirements. Natural gas gathering may receive greater regulatory scrutiny at both the state and federal levels in the future. We cannot predict what effect, if any, such changes may have on our operations,us, but the natural gas industry could be required to incur additional capital expenditures and increased costs depending on future

legislative and regulatory changes, including changes in the interpretation of existing requirements or programs to implement those requirements. We do not believe we would be affected by any such regulatory changes in a materially different way than our similarly situated competitors.

Intrastate natural gas transportation service is also subject to regulation by state regulatory agencies. Like the regulation of interstate transportation rates, the regulation of intrastate transportation rates affects the marketing of natural gas we produce, as well as the revenues we receive for sales of our natural gas. The basis for intrastate regulation of natural gas transportation and the degree of regulatory oversight and scrutiny given to intrastate natural gas pipeline rates and services varies from state to state. Insofar as such regulation within a particular state will generally affect all intrastate natural gas shippers within the state on a comparable basis, we believe the regulation of intrastate natural gas transportation in states in which we operate and ship natural gas on an intrastate basis will not affect our operationsus in a way that materially differs from the effect on the operations of our similarly situated competitors.

Regulation of Production

production

The production of crude oil and natural gas is subject to regulation under a wide range of federal, state and local statutes, rules, orders and regulations, which require, among other matters, permits for drilling operations, drilling bonds and reports concerning operations. All of the states in which we own and operate properties have regulations governing conservation, including provisions for the unitization or pooling of crude oil and natural gas properties, the establishment of maximum allowable rates of production from crude oil and natural gas wells, the regulation of well spacing, and the plugging and abandonment of wells.wells, as well as regulations that generally limit or prohibit the venting or flaring of natural gas. The effect of these regulations is to limit the amount of crude oil and natural gas we can produce from our wells and to limit the number of wells or the locations at which we can drill, although we can apply for exceptions to such regulations or to have reductions in well spacing. Moreover, each state generally imposes a production, severance or excise tax with respect to the production and sale of crude oil, natural gas and natural gas liquids within its jurisdiction.

The failure to comply with these rules and regulations can result in substantial penalties. Our similarly situated competitors in the crude oil and natural gas industry are generally subject to the same statutes, regulatory requirements and restrictions that affectrestrictions.

Dodd-Frank Wall Street Reform and Consumer Protection Act. In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was enacted into law. This financial reform legislation includes provisionsThe Dodd-Frank Act established federal oversight and regulation of the over-the-counter derivatives market and entities, such as us, that require derivative transactionsparticipate in that are currently executed over-the-counter to be executed through an exchange and be centrally cleared.market. The Dodd-Frank Act requires the CFTC, the SEC, and other regulators to establish rules and regulations to implement the new legislation. TheAlthough the CFTC has issued final regulations to implement significant aspects of the legislation, including newothers remain to be finalized or implemented and it is not possible at this time to predict when this will be accomplished.

In November 2013, the CFTC proposed rules for the registration of swap dealers and major swap participants (and related definitions of those terms), definitions of the term “swap,” rules to establish the ability to rely on the commercial end-user exception from the central clearing and exchange trading requirements, requirements for reporting and recordkeeping, rules on customer protection in the context of cleared swaps, andestablishing position limits with respect to certain futures and option contracts and equivalent swaps, subject to exceptions for swaps and other transactions based oncertain bona fide hedging. As these new position limit rules are not yet final, the price of certain reference contracts, some of which are referenced in our swap contracts.

the end-user exception from the clearing requirement for our swaps entered into to hedge our commercial risks, the application of the mandatory clearing requirements and revised capital requirements applicable to other market participants, such as swap dealers, along with changes to the markets for swaps as a result of the trade execution requirement, may change the cost and availability of the swaps we use for hedging.

The CFTC’s swap regulations may require or cause our counterparties to collect margin from us, and if If any of our swaps do not qualify for the commercial end-user exception, or if the cost of entering into uncleared swaps becomes prohibitive, we may be required to clear such transactions or execute them on a derivatives contract market or swap execution facility. The ultimate effect of the proposed new rules and any additional regulations on our business is uncertain. Of particular concern is whether

In December 2015, the CFTC issued final rules establishing minimum margin requirements for uncleared swaps for swap dealers and major swap participants. The final rules do not impose margin requirements on commercial end users. Although we expect to qualify for the end-user exception from the margin requirements for swaps entered into to hedge our statuscommercial risks, the application of such requirements to other market participants, such as aswap dealers, may change the cost and availability of the swaps we use for hedging.

In addition to the CFTC’s swap regulations, certain foreign jurisdictions are in the process of adopting or implementing laws and regulations relating to transactions in derivatives, including margin and central clearing requirements, which in each case may affect our counterparties and the derivatives markets generally. Other rules, including the restrictions on major provisionsproprietary trading adopted under Section 619 of the legislation, suchDodd-Frank Act, also known as new margin requirements, will be established through regulatory rulemaking. the Volcker Rule, may alter the business practices of some of our counterparties and in some cases may cause them to stop transacting in or making markets in derivatives. Moreover, federal banking regulators are reevaluating the authorization under which banking entities subject to their authority may engage in physical commodities transactions.
Although we cannot predict the ultimate outcome of these rulemakings, new rules and regulations, in this area, to the extent applicable to us or our derivative counterparties, may result in increased costs and cash collateral requirements for the types of derivative instruments we use to manage our financial and commercial risks related to fluctuations in commodity prices. Additional effects of the new regulations, including increased regulatory reporting and recordkeeping costs, increased regulatory capital requirements for our counterparties, and market dislocations or disruptions, among other consequences, could have an adverse effect on our ability to hedge risks associated with our business.

Additionally, the SEC had adopted rules as required under the Dodd-Frank Act requiring registrants to disclose certain payments made to the U.S. Federal government and foreign governments in connection with the commercial development of crude oil, natural gas or minerals. The disclosure requirements were challenged by certain business groups and were subsequently vacated by a Federal court in July 2013. In December 2015, the SEC issued a revised proposal for public comment. As the proposed rules are not yet final, the impact of the rules on our business is uncertain at this time.
Energy Policy Act of 2005. The Energy Policy Act of 2005 (“EPAct 2005”) included a comprehensive compilation of tax incentives, authorized appropriations for grants and guaranteed loans, and made significant changes to the statutory framework affecting the energy industry. Among other matters, EPAct 2005 amended the NGA to add an anti-market manipulation provision making it unlawful for any entity, including otherwise non-jurisdictional producers such as us, to use any deceptive or manipulative device or contrivance in connection with the purchase or sale of natural gas or the purchase or sale of transportation services subject to regulation by the FERC, in contravention of rules prescribed by the FERC. In January 2006, the FERC issued rules implementing the anti-market manipulation provision of EPAct 2005. These anti-market manipulation rules apply to activities of natural gas pipelines and storage companies that provide interstate services, as well as otherwise non-jurisdictional entities to the extent the activities are conducted “in connection with” natural gas sales, purchases or transportation subject to FERC jurisdiction, which now includes the annual reporting requirements as described further below.

The EPAct 2005 also provided the FERC with additional civil penalty authority. The EPAct 2005 provides the FERC with the power to assess civil penalties of up to $1,000,000 per day per violation for violations of the NGA and NGPA. Under EPAct 2005,NGPA and the FERC also has authority to order disgorgement of profits associated with any violation. The anti-market manipulation rules and enhanced civil penalty authority reflect an expansion of the FERC’s enforcement authority.

FERC Market Transparency and Reporting Rules. The FERC requires wholesale buyers and sellers of more than 2.2 million MMBtus of physical natural gas in the previous calendar year, including interstate and intrastate natural gas pipelines, natural gas gatherers, natural gas processors, natural gas marketers, and natural gas producers, to report, on May 1 of each year, aggregate volumes of natural gas purchased or sold at wholesale in the prior calendar year to the extent such transactions utilize, contribute to, or may contribute to the formation of price indices. The FERC also requires market participants to indicate whether they report prices to any index publishers and, if so, whether their reporting complies with the FERC’s policy statement on price reporting. Failure to comply with these reporting requirements could subject us to enhanced civil penalty liability provided under the EPAct 2005.

FTC and CFTC Market Manipulation Rules. Wholesale sales of petroleum are subject to provisions of the Energy Independence and Security Act of 2007 (“EISA”) and regulations by the FTC. Under the EISA, the FTC issued its Petroleum Market Manipulation Rule (the “Rule”), which became effective in November 4, 2009, and prohibits fraudulent or deceptive conduct (including false or misleading statements of material fact) in

connection with wholesale purchases or sales of crude oil or refined petroleum products. The Rule also bans intentional failures to state a material fact when the omission makes a statement misleading and distorts, or is likely to distort, market conditions for any product covered by the Rule. The FTC holds substantial enforcement authority underUnder the EISA, includingthe FTC has authority to request that a court to impose fines of up to $1,000,000 per day per violation. Under the Commodity Exchange Act, theThe CFTC is directed to prevent price manipulations for the commodity and futures markets, including the energy futures markets. Pursuant to the Dodd-Frank Act, the CFTC has also adopted anti-market manipulation regulations that prohibit, among other things, fraud and price manipulation in the commodity and futures markets. The CFTC also has statutory authority tomay assess fines of up to the greater of $1,000,000 or triple the monetary gain for violations of its anti-market manipulation regulations.

Knowing or willful violations of the Commodity Exchange Act may also lead to a felony conviction.

Additional proposals and proceedings that may affect the crude oil and natural gas industry are pending before the U.S. Congress, the FERC and the courts. We cannot predict the ultimate impact of these or the above regulatory changes tolaws and regulations may have on our crude oil and natural gas operations. We do not believe we will be affected by any such action in a materially different way than our similarly situated competitors.

Environmental, Healthhealth and Safety Regulationsafety regulation

Our operationsWe are subject to stringent and complex federal, state, and local laws, rules and regulations governing environmental protection, health and safety,compliance, including the discharge of materials into the environment.environment, and worker health and safety. These laws, rules and regulations may, among other things:

require the acquisition of various permits beforeto conduct exploration, drilling commences;

restrict the types, quantities and concentration of various substances that can be released into the environment in connection with crude oil and natural gas drilling, production and transportation activities;

limit or prohibit drilling activities on certain lands lying within wilderness, wetlands and other protected areas including areas containing endangered species of plants and animals; and

require remedial measures to mitigate pollution from former and ongoing operations, such as requirements to close pits and plug abandoned wells.

wells; and

impose substantial liabilities for pollution resulting from drilling and production operations.
These laws, rules and regulations may also restrict the rate of crude oil and natural gas production below a rate otherwise possible. The regulatory burden on the crude oil and natural gas industry increases the cost of doing business and affects profitability. Additionally, the U.S. Congress and federal and state agencies frequently revise environmental, health and safety laws, rules and regulations, and any changes that result in more stringent and costly waste handling, disposal, cleanup and remediation requirements for the crude oil and natural gas industry could have a significant impact on our operating costs.

Environmental protection and natural gas flaring initiatives. Continental is committed to conducting its operations in a manner that protects the health, safety and welfare of the public, its employees and the environment. We strive to operate in accordance with all applicable regulatory and legal requirements and have focused on continuously improving our health, safety, security and environmental (“HSS&E”HSE”) performance.performance; however, at times circumstances may arise that adversely affect our compliance with applicable HSE requirements. We believe excellent HSS&E performance is critical to the long-term success of our business,have established internal policies and is a key component in maximizing return to shareholders. We also believe achieving this excellence requires the commitment and involvement ofprocedures regarding HSE matters for all employees, in the Company, and we expect the same level of commitment from our contractors, and vendors. Our commitment to HSS&E excellence is a paramount objective.

In connection with our HSS&EHSE initiatives, we actively work to identify and manage theour environmental and safety risks and the impact of our operations. Further, we set corporate objectives aimed at producing continuous improvement ofoperations and improve our HSS&E efforts and we seek to provide the leadership and resources to enable our workforce to achieve our objectives.HSE efforts. We routinely monitor our HSS&EHSE performance to assess our conformitycompliance with environmental protection initiatives.

We take a proactive and disciplined approach to emergency preparednesssafety initiatives and business continuity planning to address the health, safety, security, and environmental risks inherent to our industry. We continually train our workforce and conduct drills to improve awareness and readiness to mitigate such risks. Further, emergency response plans are maintained that establish procedures to be utilized during any type of emergency affecting our personnel, facilities or the environment.

peer benchmarking with trade associations.

One current focus of our HSS&EHSE initiatives is the reduction of air emissions produced from our operations, particularly with respect to the flaring of natural gas from our operated well sites in the Bakken field of North Dakota. North Dakota statutes permit flaring of natural gas from a well that has not been connected to a gas gathering line for a period of one year from the date of a well's first production. After one year, a producer is required to cap the well, connect it to a gas gathering line, find acceptable alternative uses for a percentage of the flared gas, or apply to the NDIC for a written exemption for any future flaring; otherwise, the producer is required to pay royalties and production taxes based on the volume and value of the gas flared from the unconnected well. While the NDIC ultimately determines the volume and value of any such gas flared and the applicable royalties and production taxes, the NDIC has thus far generally accepted our most active area. The rapid growthmethods for calculating these figures. Furthermore, the NDIC has generally accepted applications we have submitted to secure exemptions from the post-year flaring restrictions. Finally, NDIC rules for new drilling permit applications also require the submission of crude oilgas capture plans that address measures taken by operators to capture and not flare produced gas, regardless of whether it has been or will be connected within the first year of production. Thus far, the NDIC has generally accepted our gas capture plans submitted with applications for drilling permits. In September 2015, the NDIC extended the deadline to comply with the requirement to capture 85% of the natural gas produced from a well by one year, with a new compliance deadline of November 1, 2016.

Compliance with the NDIC's flaring requirements or the imposition of any additional limitations on flaring could result in increased costs and have an adverse effect on our operations.
For the year ended December 31, 2015, we delivered approximately 87% of our operated natural gas production in North Dakota Bakken to market, flaring approximately 13% compared to 13% in recent years, coupled2014, 11% in 2013 and 15% in 2012. Flaring from our operated well sites in the North Dakota Bakken is less than our industry peers operating in the play. According to data published by the NDIC, our industry as a whole flared approximately 18% of produced natural gas volumes in the state during 2015. We are a participant in the NDIC’s Flaring Reduction Task Force and are engaged in working with a lackother task force members and the NDIC to develop action plans for mitigating natural gas flaring in the state. Flared natural gas volumes from our operated SCOOP, Northwest Cana and STACK properties in Oklahoma are negligible given the existence of established natural gas transportation infrastructure in the state, has led to an industry-wide increase in flaring of natural gas produced in association with crude oil production. We recognize theinfrastructure.
There are environmental and financial risks associated with natural gas flaring and we attempt to manage these risks on an ongoing basis. We set internal flaring reduction targets and toTo date, we have taken numerous actions to reduce flaring from our operated well sites. We make efforts to coordinate our well completion operations to coincide with well connections to gathering systems in order to minimize flaring, but may not always be successful in these efforts. Our ultimate goal is to reduce natural gas flaring from our operated well sites to as close to zero percent flaringmuch as possible. Inis practicable. For example, in operating areas such as the Buffalo Red River units in South Dakota, the quality of the natural gas is not adequate to meet requirements for sale, so we employ processes to efficiently combust the gas andin an effort to minimize impacts to the environment.

In 2012, we made significant progress in achieving our Our levels of flaring reduction goals. For example, in 2012 we set a goal to reduce the flaring of natural gas from our operated well sites in North Dakota Bakken by 50% by December 2012. During December 2012, the percentage of our natural gas production flared in North Dakota Bakken was approximately 10% compared to approximately 20% in December 2011. We believe this reduction is a notable accomplishment given the significant increase in our natural gas production in 2012, including areas with less developed infrastructure. Flaring from our operated well sites in North Dakota Bakken is significantly less than our industry peers operating in the play. According to data published by the North Dakota Industrial Commission, our industry as a whole was flaring approximately 33% of produced natural gas volumes in the state as of late 2012. Since we are one of the largest producers in the North Dakota Bakken field, we believe the percentage of natural gas flared by the industry as a whole would be higher than 33% if Continental’s results were excluded from the NDIC’s data.

We are experiencing similar or better flaring results in our other key operating areas outside of North Dakota. In Montana Bakken, we flared approximately 6% of the natural gas produced from our operated well sites in December 2012. Additionally, flared natural gas volumes from our operated SCOOP and Northwest Cana properties in Oklahoma are negligible given the existence of established natural gas transportation infrastructure in that state.

Through our HSS&E global initiatives, we will continue to work toward maintaining an industry-leading position with respect to flaring reduction efforts in North Dakota and our other key operating areas. In the Medicine Pole Hills units, we substantially reduced impacts from flaring by removing all gas engines that drive high pressure air injection and converting to electric engines. We expect to further reduce flared natural gas volumes as we continue to build out transportation infrastructure and transition to a greater use of ECO-Pad drilling in 2013 and beyond. Our flaring reduction progress is and will be dependent upon external factors such as investment from third parties in the development of gas gathering systems, state regulations, and the granting of reasonable right-of-way access by land owners, among other factors.

We have incurred in the past, and expect to incur in the future, capital and other expenditures related to environmental compliance. Such expenditures are included within our overall capital and operating budgets and are not separately itemized. Although we believe our continued compliance with existing requirements will not have a material adverse impact on our financial condition and results of operations, we cannot assure you that the passage of more stringent laws or regulations in the future will not materially impact our financial position, or results of operations.

Environmental, health and safety laws, rules and regulations. Some of the existing environmental and worker health and safety laws, rules and regulations to which we are subject to include, among others: (i) regulations by the Environmental Protection Agency (“EPA”) and various state agencies regarding approved methods of disposal for certain hazardous and nonhazardous wastes; (ii) the Comprehensive Environmental Response, Compensation, and Liability Act and analogous state laws that may require the removal of previously disposed wastes (including wastes disposed of or released by prior owners or operators), the cleanup of property contamination (including groundwater contamination), and remedial plugging operationslease restoration activities to prevent future contamination;contamination from prior operations; (iii) federal Department of Transportation safety laws and comparable state and local requirements; (iv) the Clean Air Act and comparable state and local requirements, which establish pollution control requirements with respect to air emissions from our operations; (v) the Oil Pollution Act of 1990, which contains numerous requirements relating to the prevention of and response to oil spills into waters of the United States; (vi) the Federal Water Pollution Control Act, or the Clean Water Act, and analogous state laws which impose restrictions and strict controls with respect to the discharge of pollutants, including crude oil and other substances generated by our operations, into waters of the United States or state waters; (vii) the Resource Conservation and Recovery Act, which is thea principal federal statute governing the treatment, storage and disposal of solid and hazardous wastes, and comparable state statutes; (viii) the Safe Drinking Water Act and analogous state laws which impose requirements relating to our underground injection activities; (ix) the National Environmental Policy Act and comparable state statutes, which require government agencies, including the Department of Interior, to evaluate major agency actions that have the potential to significantly impact the environment; (x) the federal Occupational SafetyEndangered Species Act and Healthcomparable state statutes, which afford protections to certain plant and animal species; (xi) the Migratory Bird Treaty Act, which imposes certain restrictions for the protection of migratory birds; (xii) the Bald and Golden Eagle Protection Act, which imposes certain restrictions for the protection of bald and golden eagles; (xiii) the Emergency Planning and Community Right to Know Act and comparable state statutes, which require that we organize and/or disclose information about hazardous materials stored, used or produced in our operations, and (xi)(xiv) state regulations and statutes governing the handling, treatment, storage and disposal of naturally occurring radioactive material. Any failure to comply with these laws, rules and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of corrective or remedial obligations, the issuance of orders enjoining performance of some or all of our operations, and potential litigation.

ClimateAir emissions and climate change. Federal, state and local laws and regulations are increasingly being enacted to address concerns about the effects the emission of carbon dioxide and other identified “greenhouse gases” may have on the environment and climate worldwide. These effects are widelyworldwide, generally referred to as “climate change.” Since its December 2009 endangerment finding regarding the emission of carbon dioxide, methane and other greenhouse gases,For example, the EPA has begun regulatingadopted regulations under existing provisions of the federal Clean Air Act ("CAA") establishing, among other things, Prevention of Significant Deterioration (“PSD”) and construction and Title V operating permit reviews for certain large stationary sources. Facilities required to obtain PSD permits for greenhouse gas emissions are also required to meet “best available control technology” standards established on a case-by-

23



case basis. We currently do not have any facilities that are required to adhere to the PSD or Title V permit requirements; however, attempts by the EPA to aggregate multiple oil and gas production facilities, each of which is currently and has long been regarded as an individual stationary source, for permitting purposes could result in the aggregate emissions from these independent facilities triggering Title V and/or PSD requirements. EPA rulemakings related to greenhouse gas emissions could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources.
In addition, the EPA has adopted rules requiring the monitoring and reporting of greenhouse gas emissions from specified onshore and offshore oil and gas production sources in the United States on an annual basis, which include certain of our operations. In August 2015, the EPA proposed new regulations setting methane emission standards for new and modified oil and gas production and natural gas processing and transmission facilities as part of the Obama Administration’s efforts to reduce methane emissions from the oil and gas sector by up to 45% from 2012 levels by 2025 even though there is consensus that oil and gas producers’ compliance with EPA's New Source Performance Standard Subpart OOOO, which was promulgated in 2012, has already achieved the methane reductions which are now being targeted by the recently proposed regulations. The proposed regulations are expected to be finalized in 2016. On January 22, 2016, the Bureau of Land Management issued a pre-publication version of a proposed venting and flaring rule, which is expected to be finalized in 2016 and, like the forthcoming EPA regulations, will address methane emissions from crude oil and natural gas sources. To the extent the new regulations impose reporting obligations on, or limit emissions of greenhouse gases from, our equipment and operations they could require us to incur costs to reduce emissions associated with our operations, the impact of which, though uncertain at this time as the regulations are not yet final, is not expected to be material and will not affect us in a way that materially differs from our similarly situated competitors.
In December 2015, a global climate agreement was reached in Paris at the 21st Conference of Parties organized by the United Nations under the Framework Convention on Climate Change. The agreement, which goes into effect in 2020, resulted in nearly 200 countries, including the United States, committing to work towards limiting global warming and agreeing to a monitoring and review process of greenhouse gas emissions. The agreement includes binding and non-binding elements and did not require ratification by the U.S. Congress. Nonetheless, the agreement may result in increased political pressure on the United States to ensure continued compliance with enforcement measures under the Clean Air Act and may spur further initiatives aimed at reducing greenhouse gas emissions in the future.
While the U.S. Congress has from time to time considered legislation to reduce emissions of greenhouse gases, there has not been significant activity in the form of adopted legislation to reduce greenhouse gas emissions at the federal level in recent years. In the absence of such federal legislation, a number of state and regional efforts have emerged that are aimed at tracking and reducing greenhouse gas emissions by means of cap and trade programs that typically require major sources of greenhouse gas emissions, under the federal Clean Air Act. Among severalsuch as electric power plants, to acquire and surrender emission allowances in return for emitting those greenhouse gases. Although it is not possible at this time to predict how such legislation or new regulations requiring reporting or permitting foradopted to address greenhouse gas sources, the EPA finalized its “tailoring rule” in May 2010 that identifies which stationary sourcesemissions would impact our business, any future laws and regulations imposing reporting obligations on, or limiting emissions of greenhouse gases are requiredfrom, our equipment and operations could require us to obtain permitsincur costs to construct, modify or operatereduce emissions of greenhouse gases associated with our operations. In addition, substantial limitations on account of, and to implement the best available control technology for, their greenhouse gases. In November 2010, the EPA also finalized its greenhouse gas reporting requirements for certain oil and gas production facilities that emit 25,000 metric tons or more of carbon dioxide equivalent per year. The rule requires annual reporting to the EPA of greenhouse gas emissions bycould adversely affect the demand for the crude oil and natural gas we produce. Finally, it should be noted that some scientists have concluded that increasing concentrations of greenhouse gases in the Earth’s atmosphere may produce climate changes that have significant physical effects, such regulated facilities.

On April 17, 2012,as increased frequency and severity of storms, floods and other climatic events. If any such effects from such causes were to occur, they could have an adverse effect on our exploration and production operations.

With respect to air quality regulation more generally, the EPA issued final rules thathas also established new air emission controls for crude oil and natural gas production and natural gas processing operations. These rules were published inoperations under the Federal Register on August 16, 2012. The EPA’s rule package includesCAA's New Source Performance Standards and National Standards for Emission of Hazardous Air Pollutants programs. With regard to address emissionsproduction activities, the rules require, among other things, the reduction of sulfur dioxide and volatile organic compoundscompound (“VOCs”VOC”) emissions from three subcategories of fractured and refractured gas wells for which well completion operations are conducted: wildcat (exploratory) and delineation gas wells; low reservoir pressure non-wildcat and non-delineation gas wells; and all “other” fractured and refractured gas wells. All three subcategories of wells must route flowback emissions to a separate set of emission standards to address hazardous air pollutants frequently associated with crude oilgathering line or be captured and natural gas production and processing activities. The final rules requirecombusted using a combustion device such as a flare. However, the “other” wells must use of reduced emission completions or “green completions” on all hydraulically-fractured wells completed or refractured after January 1, 2015 in order to achieve a 95 percent reduction in the emission of VOCs.completions.” The rules also establishestablished specific new requirements regarding emissions from compressors, controllers, dehydrators, storage tanks and other production equipment. TheseThe rules may require modificationsare designed to our operations, including the installation of new equipment to control emissions from our wells by January 1, 2015. Compliance with such rules could result in significant costs, including increased capital expenditures and operating costs, and could adversely impact our business.

Moreover, in recent years the U.S. Congress has considered establishing a cap-and-trade program to reduce U.S.limit emissions of greenhouse gases, including carbonVOCs, sulfur dioxide, and methane. Under past proposals, the EPA would issue or sellhazardous air pollutants from a capped and steadily declining numbervariety of tradable emissions allowances to certain major sources of greenhousewithin natural gas emissions so that such sources could continue to emit greenhouse gases into the atmosphere.

These allowances would be expected to escalate significantly in cost over time. The net effect of such legislation, if adopted, would be to impose increasing costs on the combustion of carbon-based fuels such as crude oil, refined petroleum products, and natural gas. In addition, while the prospect for such cap-and-trade legislation by the U.S. Congress remains uncertain, several states, including states in which we operate, have adopted, or are in the process of adopting, similar cap-and-trade programs.

As a crudeprocessing plants, oil and natural gas company, the debate on climate change is relevant to our operations because the equipment we use to explore for, develop and produce crude oilproduction facilities, and natural gas emits greenhouse gases. Additionally, the combustion of carbon-based fuels, suchtransmission compressor stations. We have modified our operations and well equipment as the crude oil and natural gas we sell, emits carbon dioxide and other greenhouse gases. Thus, any current or future federal, state or local climate change initiatives could adversely affect demand for the crude oil and natural gas we produce by stimulating demand for alternative forms of energy that do not rely on the combustion of fossil fuels, and therefore could have a material adverse effect on our business. Although ourneeded to comply with these rules. Ongoing compliance with any greenhouse gas regulations maythe rules is not expected to affect us in a way that materially differs from our similarly situated competitors. In addition, in October 2015 the EPA revised the National Ambient Air Quality Standard (“NAAQS”) for ozone from 75 to 70 parts per billion for both the 8-hour primary and secondary standards. State implementation of the revised NAAQS could result in stricter permitting requirements, delay or prohibit our ability to obtain such permits, and result in increased compliance and operatingexpenditures for pollution control equipment, the costs we do not expect the compliance costs for currently applicable regulations toof which could be material. Moreover, while it is not possible at this time to estimate the compliance costs or operational impacts for any new legislative or regulatory developments in this area, we do not anticipate being impacted to any greater degree than other similarly situated competitors.

Hydraulic fracturing. Hydraulic fracturing involves the injection of water, sand and additives under pressure into rock formations to stimulate crude oil and natural gas production. Some activists have attempted to linkIn recent years there has been increased public concern regarding an alleged potential for hydraulic fracturing to various environmental problems, including adverse effects toadversely affect drinking water supplies and migration of methane and other hydrocarbons.to induce seismic events. As a result, several federal and state agencies are studying the environmental risks with respect to hydraulic fracturing, or evaluating whetherand proposals have been made to restrict its use. From timeenact separate federal, state and local legislation that would increase the regulatory burden imposed on hydraulic fracturing.
Also at the federal level, the EPA has asserted federal regulatory authority pursuant to time, legislation has been introduced in the U.S. Congress to amend the federal Safe Drinking Water Act to eliminate an existing exemption for(“SDWA”) over certain hydraulic fracturing activities frominvolving the definitionuse of “underground injection,” thereby requiringdiesel fuels and published permitting guidance in February 2014 related to such activities. In May 2014, the crude oil and natural gas industryEPA issued an Advance Notice of Proposed Rulemaking to obtain permits for hydraulic fracturing and to require disclosure of the additives used in the process. If adopted, such legislation could establish an additional level of regulation and permitting at the federal level. Scrutiny of hydraulic fracturing activities continues in other ways. The White House Councilcollect data on Environmental Quality is coordinating an administration-wide review of hydraulic fracturing practices, and a number of federal agencies are analyzing environmental issues associated with hydraulic fracturing. The EPA has commenced a multi-year study of the potential environmental impacts of hydraulic fracturing, the draft results of which are anticipated to be available in 2014. Further, on May 11, 2012, the Bureau of Land Management (“BLM”) issued a proposed rule that would require public disclosure of chemicals used in hydraulic fracturing operations and imposeunder Section 8 of the Toxic Substances Control Act. To date, no other operational requirements for allaction has been taken. Further, in April 2015 the EPA issued proposed regulations under the Clean Water Act governing discharges to publicly owned treatment works of waste water from hydraulic fracturing operationsand certain other natural gas operations. In 2015 the EPA completed a study of the potential impacts of hydraulic fracturing activities on water resources and published a draft assessment in June 2015 for peer review and public comment. In its assessment, the EPA indicated it did not find evidence that hydraulic fracturing mechanisms caused widespread, systemic impacts on drinking water resources in the United States. Nonetheless, the results of the study or similar governmental reviews could spur initiatives to regulate hydraulic fracturing under the SDWA or otherwise, and there has been recent speculation the EPA may conduct a second similar study. Finally, the U.S. Department of Interior issued final rules in March 2015 related to the regulation of hydraulic fracturing activities on federal lands, including Native American trust lands.requirements for chemical disclosure, well bore integrity and handling of flowback water. The DepartmentU.S. District Court of Wyoming has temporarily stayed implementation of this rule and a final decision remains pending.
At the Interior announced on January 18, 2013 that the BLM will issue a revised draft rule by March 31, 2013. In addition to these federal initiatives,state level, several state and local governments,states, including states in which we operate, have movedadopted or are considering adopting legal requirements imposing more stringent permitting, disclosure and well construction requirements on hydraulic fracturing activities. Local governments also may seek to require disclosureadopt ordinances within their jurisdictions regulating the time, place and manner of drilling activities in general or hydraulic fracturing fluid componentsactivities in particular or otherwise to regulate their use more closely.prohibit the performance of well drilling in general or hydraulic fracturing in particular. In certain areas of the United States, new drilling permits for hydraulic fracturing have been put on hold pending development of additional standards.
We voluntarily participate in FracFocus, a national publicly accessible Internet-based registry developed by the Ground Water Protection Council and the Interstate Oil and Gas Compact Commission. This registry, located atwww.fracfocus.org, provides our industry with an avenue to voluntarily disclose additives used in the hydraulic fracturing process. We currently disclose theThe additives used in the hydraulic fracturing process on all wells we operate.operate are disclosed on that website.

The adoption of any future federal, state or local laws, rules or implementing regulations imposing permitting or reporting obligations on, or otherwise limiting, the hydraulic fracturing processprocesses in areas in which we operate could make it more difficult and more expensive to complete crude oil and natural gas wells in low-permeability formations, increase our costs of compliance and doing business, and delay, prevent or prohibit the development of natural resources from unconventional formations. Compliance, or the consequences of our failure to comply, could have a material adverse effect on our financial condition and results of operations. At this time it is not possible to estimate the potential impact on our business if such federal or state legislation is enacted into law.

Waste water disposal. Underground injection wells are a predominant method for disposing of waste water from oil and gas activities. In response to recent seismic events near underground injection wells used for the disposal of oil and gas-related waste waters, federal and some state agencies are investigating whether such wells have caused increased seismic activity. Some states, including states in which we operate, have delayed permit approvals, mandated a reduction in injection volumes, or have shut down or imposed moratoria on the use of injection wells. Regulators in some states, including states in which we operate, are considering additional requirements related to seismic safety. For example, the Oklahoma Corporation Commission (“OCC”) has adopted rules for operators of saltwater disposal wells in certain seismically-active areas in the Arbuckle formation of Oklahoma. These rules require, among other things, that disposal well operators conduct mechanical integrity testing or make certain demonstrations of such wells’ respective depths that, depending on the depth, could require plugging the well and/or the reduction of volumes disposed in such wells. Oklahoma has adopted a “traffic light” system, wherein the OCC reviews new or existing disposal wells for proximity to faults, seismicity in the area and other factors in determining whether such wells should be permitted, permitted only with special restrictions, or not permitted. At the federal level, the EPA's current regulatory requirements for such wells do not require the consideration of seismic impacts when issuing permits. We cannot predict the EPA's future actions in this regard. The introduction of new environmental initiatives and regulations related to the disposal of wastes associated with the exploration, development or production of hydrocarbons, could limit or prohibit our ability to utilize underground injection wells. A lack of waste water disposal sites could cause us to delay, curtail or discontinue our exploration and development plans. Additionally, increased costs associated with the transportation and disposal of produced water, including the cost of complying with regulations concerning produced water disposal, may reduce

25



our profitability. These costs are commonly incurred by all oil and gas producers and we do not believe the costs associated with the disposal of produced water will have a material adverse effect on our operations to any greater degree than other similarly situated competitors. In 2015, we began operation of water recycling facilities in the SCOOP area that economically reuse stimulation water for both operational efficiencies and environmental benefits.

You should carefully consider each of the risks described below, together with all other information contained in this report before deciding to invest in shares ofconnection with an investment in our common stock.securities. If any of the following risks develop into actual events, our business, financial condition or results of operations could be materially adversely affected, the trading price of your sharesour securities could decline and you may lose all or part of your investment.

We are subject to certain risks and hazards due to the nature

Substantial declines in commodity prices or extended periods of the business activities we conduct. The risks discussed below, any of which could materially andhistorically low commodity prices adversely affect our business, financial condition, cash flows, and results of operations are not the only risks we face. We may experience additional risks and uncertainties not currently known to us or, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect our business, financial condition, cash flows and results of operations.

A substantial or extended decline in crude oil and natural gas prices may adversely affect our business, financial condition or results of operations and our ability to meet our capital expenditure needs and financial commitments.

The priceprices we receive for sales of our crude oil and natural gas production heavily influencesinfluence our revenue, profitability, access to capital, capital budget and future rate of growth. Crude oil and natural gas are commodities and therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand.demand, as evidenced by the significant decrease in crude oil and natural gas prices in 2014 and 2015, which has continued into 2016. Historically, the

markets for crude oil and natural gas have been volatile. These markets willvolatile and unpredictable. For example, the NYMEX West Texas Intermediate crude oil and Henry Hub natural gas spot prices ranged widely from approximately $35 to $61 per barrel and $1.63 to $3.32 per MMBtu, respectively, during 2015. Commodity prices are likely continue to beremain volatile and unpredictable in the future. 2016.

Our crude oil sales for future periods are currently unhedged and directly exposed to continued volatility in crude oil market prices, whether favorable or unfavorable. Additionally, a portion of our natural gas sales for future periods are unhedged and directly exposed to continued volatility in natural gas market prices, whether favorable or unfavorable.
The prices we receive for our production, and the levelssales of our production depend on numerous factors beyond our control. These factors include, but are not limited to, the following:

worldwide, domestic and regional economic conditions impacting the global supply of, and demand for, crude oil and natural gas;

the actions of the Organization of Petroleum Exporting Countries;

the priceCountries and quantity of imports of foreign crude oil and natural gas;

political conditions in or affecting other crude oil-producing and natural gas-producing countries;

producing nations;

the level of national and global crude oil and natural gas exploration and production;

production activities;

the level of national and global crude oil and natural gas inventories;

inventories, which may be impacted by levels of economic sanctions applied to certain producing nations;

the level and effect of trading in commodity futures markets;

the price and quantity of imports of foreign crude oil;

Lower crude oil and natural gas

Sustained material declines in commodity prices could reduce our cash flows available for capital expenditures, repayment of indebtedness and other corporate purposes; result in a decrease in the borrowing base under our revolving credit facility or otherwisemay limit our ability to borrow money or raise additional capital; and may reduce our proved reserves and the amount of crude oil and natural gas we can economically produce.

Substantial, extended decreases

Crude oil prices remained significantly depressed in 2015 and face continued downward pressure, with crude oil prices dropping below $27 per barrel in early 2016. Natural gas prices faced similar downward pressure in 2015, dropping below

27



$1.70 per MMBtu in December 2015. We have established our 2016 capital program to be reflective of the current commodity price environment which will result in a reduction in our operated rig count and deferral of certain drilling projects and well completion activities in 2016. These actions could have an adverse effect on our business, financial condition, results of operations and cash flows.
In addition to reducing our revenue, cash flows and earnings, depressed prices for crude oil and natural gas may adversely affect us in a variety of ways. If commodity prices would render uneconomic a significant portiondo not improve or further decrease, some of our exploration and development projects could become uneconomic, and exploitation projects. Thiswe may result inalso have to make significant downward adjustments to our estimated proved reserves and our estimates of the present value of those reserves. If these price effects occur, or if our estimates of production or economic factors change, accounting rules may require us to write down the carrying value of our crude oil and natural gas properties. Lower commodity prices may also reduce our access to capital and lead to a downgrade or other negative rating action with respect to our credit rating, as was the case in February 2016 when our corporate credit rating was downgraded by Standard & Poor's Ratings Services ("S&P") and Moody's Investor Services, Inc. ("Moody's") in response to weakened oil and gas industry conditions and resulting revisions made to rating agency commodity price assumptions. These downgrades negatively impact our cost of capital, increase the borrowing costs under our revolving credit facility and $500 million term loan due in November 2018 (“three-year term loan”), and may limit our ability to access capital markets and execute aspects of our business plans. As a result, a substantialan extended continuation of the current commodity price environment, or extended declinefurther declines in crude oil or natural gascommodity prices, wouldwill materially and adversely affect our future business, financial condition, results of operations, cash flows, liquidity orand ability to finance planned capital expenditures.

A substantial portion of our producing properties areis located in the North region,limited geographic areas, making us vulnerable to risks associated with having operationsgeographically concentrated in this geographic area.

Becauseoperations.

A substantial portion of our operations areproducing properties is geographically concentrated in the Bakken field of North region (78%Dakota and Montana, with that area comprising approximately 62% of our crude oil and natural gas production and approximately 69% of our crude oil and natural gas revenues for the year ended December 31, 2015. Approximately 54% of our estimated proved reserves were located in the fourth quarterBakken as of 2012 was fromDecember 31, 2015.

Approximately 42% of our estimated proved reserves were located in Oklahoma as of December 31, 2015.
Because of this concentration in limited geographic areas, the success and profitability of our operations may be disproportionallydisproportionately exposed to the effect of regional events.factors relative to our competitors that have more geographically dispersed operations. These factors include, among others, fluctuations inothers: (i) the prices of crude oil and natural gas produced from wells in the regionregions and other regional supply and demand factors, including gathering, pipeline and rail transportation capacity constraints, availableconstraints; (ii) the availability of rigs, equipment, oil field services, supplies, labor and labor; (iii) the availability of processing and refining facilities; and (iv) infrastructure capacity. In addition, our operations in the North regionBakken field and Oklahoma may be adversely affected by seasonalsevere weather events such as floods, blizzards, ice storms and lease stipulations designed to protect wildlife,tornadoes, which can intensify competition for the items described above during months when drilling is possible and may result in periodic shortages. The concentration of our operations in the North regionlimited geographic areas also increases our exposure to changes in local laws and regulations, certain lease stipulations designed to protect wildlife, and unexpected events that may occur in this regionthe regions such as natural disasters, seismic events, industrial accidents or labor difficulties. Any one of these events has the potential to cause producing wells to be shut-in, delay operations, and growth plans, decrease cash flows, increase operating and capital costs and prevent development of lease inventory before expiration. Any of the risks described above could have a material adverse effect on our financial condition, and results of operations.

Volatility in the financial markets or in global economic factors could adversely impact our business and financial condition.

The economic recession experienced in 2008-2009 led to turmoil in U.S.

United States and global economies that wasmay experience periods of turmoil and volatility from time to time, which may be characterized by extreme volatility and declines in prices of securities, diminished liquidity and credit availability, inability to access capital markets, the bankruptcy, failure, collapse or sale of financial institutions, increased levels of unemployment, and an unprecedented level of intervention by the U.S. federal government and other governments. Improvements have occurred since 2008-2009 and some portions of the economy have stabilized and are showing signs of recovery. However, U.S. and global economies remain fragile and are still experiencing high unemployment, unstable consumer confidence, and diminished consumer demand and spending. Recent data has suggested the U.S. economy may be contracting again. Accordingly, although theRecently, certain global economies have experienced periods of political unrest, slowing economic recession experienced in recent years has ended, the extentgrowth, rising interest rates, changing economic sanctions, and timing of the current recovery, and whether it can be sustained are uncertain. Economic weakness or uncertainty could reduce demand for crude oil and natural gas andcurrency volatility. These global macroeconomic conditions continue to put significant downward pressure on the prices of crude oil prices, and natural gas.a continuation of that trend could continue or exacerbate that pressure. This would negatively impactimpacts our revenues, margins, profitability, operating cash flows, liquidity and financial condition. Such weakness or uncertainty could also cause our commodity hedging arrangements to become economically ineffective if our counterparties are unable to perform their obligations or seek bankruptcy protection. Furthermore, our ability to collect receivables may be adversely impacted.

Historically, we have used cash flows from operations, borrowings under our revolving credit facility and proceeds from capital market transactions to fund capital expenditures. Volatility in U.S. and global financial and equity markets, including market

We have an existinga revolving credit facility with lender commitments totaling $1.5$2.75 billion, andwhich may be increased up to a borrowing basetotal of $3.25$4.0 billion as of February 15, 2013.upon agreement with participating lenders. In the future, we may not be able to access adequate funding under our revolving credit facility as a result of (i) a decrease in our borrowing base due to the outcome of a subsequent borrowing base redetermination, which is solely at the discretion ofif our lenders are unwilling or (ii) an unwillingness or inability on the part of our lending counterpartiesunable to meet their funding obligations or increase their commitments tounder the borrowing base amount. Declines in commodity prices could result in a determination to lower our borrowing base in the future and, in such case, we could be required to repay indebtedness in excess of the borrowing base.credit facility. Due to these and other factors, we cannot be certain that funding, if needed, will be available to the extent required andor on terms we find acceptable. If we are unable to access funding when needed on acceptable terms, we may not be able to fully implement our business plans, fund our capital program and commitments, complete new property acquisitions to replace reserves, take advantage of business opportunities, respond to competitive pressures, or refinance debt obligations as they come due.

Our exploration, development and exploitation projects require substantial capital expenditures. We may be unable to obtain needed capital or financing on acceptable terms, which could lead to a decline in our crude oil and natural gas reserves, production and production.

revenues. In addition, funding our capital expenditures with additional debt will increase our leverage and doing so with equity securities may result in dilution that reduces the value of your stock.

The crude oil and natural gas industry is capital intensive. We make and expect to continue to make substantial capital expenditures in our business for the exploration, development, exploitation, production and acquisition of crude oil and natural gas reserves. In 2012,2015, we invested approximately $4.4$2.56 billion in our capital program, inclusive of property acquisitions. In October 2012, we announced a new five-year growth plan to triple our production and proved reserves from year-end 2012 to year-end 2017. OurWe have budgeted $920 million for capital expenditures for 2013 are budgeted to be $3.6 billion, excludingin 2016 (excluding acquisitions which are not budgeted, with $3.3 billionbudgeted) of which $784 million is allocated for drilling,exploration and development drilling. Our planned 2016 capital workovers and facilities. To date,expenditures are substantially lower than our 2015 expenditures as a result of a planned reduction in spending prompted by significantly depressed commodity prices. We may find that additional reductions in our 2016 capital spending become necessary depending on market conditions.
Historically, our capital expenditures have been financed with cash generated by operations, borrowings under our revolving credit facility and proceeds from the issuance of debt and equity securities. The actual amount and timing of future capital expenditures may differ materially from our estimates as a result of, among others, changes in commodity prices, available cash flows, lack of access to capital, unbudgeted acquisitions, actual drilling results, the availability of drilling rigs and other services and equipment, the availability of transportation

capacity, and regulatory, technological and competitive developments. Improvement

Our cash flows from operations and access to capital are subject to a number of variables, including but not limited to:
the volume and value of our proved reserves;
the volume of crude oil and natural gas we are able to produce and sell from existing wells;
the prices at which crude oil and natural gas are sold;
our ability to acquire, locate and produce new reserves; and
the ability and willingness of our lenders to extend credit or of participants in the capital markets to invest in our senior notes or equity securities.
As a result of weakened oil and gas industry conditions from lower commodity prices, our ability to borrow may result in andecrease and we may have limited ability to obtain the capital necessary to sustain our operations at planned levels. Our revolving credit facility has lender commitments totaling $2.75 billion, which may be increased up to a total of $4.0 billion upon agreement with participating lenders. However, we can offer no assurance that our existing or other lenders would be willing to increase in actualtheir commitments under our credit facility. Such lenders could decline to do so based on our financial condition, the financial condition of our industry or the economy as a whole or other reasons beyond our control. If cash generated by operations or cash available under our revolving credit facility is not sufficient to meet capital expenditures. Conversely, a significant decline in commodity pricesrequirements and commitments, the failure to obtain additional financing could result in a decreasecurtailment of operations relating to development of our prospects, which in actual capital expenditures. turn could lead to a decline in our crude oil and natural gas reserves and could adversely affect our business, financial condition, results of operations, and cash flows.
We intend to finance future capital expenditures primarily through cash flows from operations, andwith any cash flow deficiencies expected to be funded by borrowings under our revolving credit facility; however,facility. However, our financing needs may require us to alter or increase our capitalization substantially through the issuance of debt or equity securities or the sale of assets. The issuance of additional debt requireswill require a portion of our cash flows from operations to be used for the payment of interest and principal on our debt, thereby reducing our ability to use cash flows to fund working capital needs, capital expenditures and acquisitions. The issuance of additional equity securities could have a dilutive effect on the value of our common stock.

Our cash flows from operations and access to capital are subject to a number of variables, including:


the amount of our proved reserves;

29


the volume of crude oil and natural gas we are able to produce and sell from existing wells;



the prices at which crude oil and natural gas are sold;

our ability to acquire, locate and produce new reserves; and

the ability and willingness of our banks to extend credit.

If revenues or the borrowing base under our revolving credit facility decrease as a result of lower crude oil or natural gas prices, operating difficulties, declines in reserves or for any other reason, we may have limited ability to obtain the capital necessary to sustain our operations at current levels. If additional capital is needed, we may not be able to obtain debt or equity financing. If cash generated by operations or cash available under our revolving credit facility is not sufficient to meet capital requirements, the failure to obtain additional financing could result in a curtailment of operations relating to development of our prospects, which in turn could lead to a decline in our crude oil and natural gas reserves and could adversely affect our business, financial condition and results of operations and our ability to achieve our growth plan.

Drilling for and producing crude oil and natural gas are high risk activities with many uncertainties that could adversely affect our business, financial condition or results of operations.

Our future financial condition and results of operations will depend on the success of our exploration, development and production activities. Our crude oil and natural gas exploration and production activities are subject to numerous risks, beyond our control, including the risk that drilling will not result in commercially viable crude oil or natural gas production. Our decisions to purchase, explore, develop or otherwise exploit prospects or properties will depend in part on the evaluation of data obtained through geophysical and geological analyses, production data, and engineering studies, the results of which are often inconclusive or subject to varying interpretations. Our cost of drilling, completing and operating wells may be uncertain before drilling commences.

Risks we face while drilling include, but are not limited to, failing to place our well bore in the desired target producing zone; not staying in the desired drilling zone while drilling horizontally through the formation; failing to run our casing the entire length of the well bore; and not being able to run tools and other equipment consistently through the horizontal well bore. Risks we face while completing our wells include, but are not limited to, not being able to fracture stimulate the planned number of stages; failing to run tools the entire length of the well bore during completion operations; and not successfully cleaning out the well bore after completion of the final fracture stimulation stage.

Further, many factors may curtail, delay or cancel scheduled drilling projects, including:

including but not limited to:

abnormal pressure or irregularities in geological formations;

shortages of or delays in obtaining equipment andor qualified personnel;

shortages of or delays in obtaining components used in fracture stimulation processes such as water and proppants;

mechanical difficulties, fires, explosions, equipment failures or accidents, including ruptures of pipelines equipment failures or accidents;

train derailments;

adverse weather conditionsrestrictions on the use of underground injection wells for disposing of waste water from oil and natural disasters, such as flooding, blizzards and ice storms;

gas activities;

political events, public protests, civil disturbances, terrorist acts or cyber attacks;

reductionsdecreases in, or extended periods of historically low, crude oil and natural gas prices;

limited availability of financing with acceptable terms;

title problems;

environmental hazards, such as uncontrollable flows of crude oil, natural gas, brine, well fluids, hydraulic fracturing fluids, toxic gas or other pollutants into the environment, including groundwater and shoreline contamination;

spillage or mishandling of crude oil, natural gas, brine, well fluids, hydraulic fracturing fluids, toxic gas or other pollutants by us or by third party service providers;

limitations in infrastructure, including transportation, processing and refining capacity, or the marketmarkets for crude oil and natural gas; and

delays imposed by or resulting from compliance with regulatory requirements.

requirements including permitting.

Additionally, severe weather conditions and natural disasters such as flooding, tornadoes, seismic events, blizzards and ice storms affecting the areas in which we operate, including our corporate headquarters, could have a material adverse effect on our operations. The consequences of such events may include the evacuation of personnel, damage to drilling rigs or pipeline and rail transportation facilities, an inability to access well sites, destruction of information and communication systems, and the disruption of administrative and management processes, any of which could hinder our ability to conduct normal operations and could adversely affect our business, financial condition, results of operations and cash flows
Reserve estimates depend on many assumptions that maywill turn out to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.

The Company's current estimates of reserves could change, potentially in material amounts, in the future, in particular due to a continued decline in, or an extended period of historically low, commodity prices.

The process of estimating crude oil and natural gas reserves is complex.complex and inherently imprecise. It requires interpretation of available technical data and many assumptions, including assumptions relating to current and future economic conditions, production rates, drilling and operating expenses, and commodity prices. Any significant inaccuracy in these interpretations or assumptions could materially affect our estimated quantities and present value of our reserves. SeePart I, Item 1. Business—

Crude Oil and Natural Gas Operations, Operations—Proved Reserves for information about our estimated crude oil and natural gas reserves, PV-10, and Standardized Measure of discounted future net cash flows as of December 31, 2012.2015.

In order to prepare reserve estimates, we must project production rates and the amount and timing of development expenditures. Our booked proved undeveloped reserves must be developed within five years from the date of initial booking under SEC reserve rules. Changes in the timing of development plans that impact our ability to develop such reserves in the required time frame have resulted, and may in the future result, in fluctuations in reserves between periods as reserves booked in one period may need to be removed in a subsequent period. In 2015, 98 MMBoe of proved undeveloped reserves were removed from our year-end reserve estimates due to various factors, including removals associated with drilling locations no longer scheduled to be developed within five years from the date of initial booking. Additionally, decreases in commodity prices in 2015 shortened the economic lives of certain producing properties and caused certain exploration and development projects to become uneconomic, which resulted in downward reserve revisions totaling 251 MMBoe in 2015.
We must also analyze available geological, geophysical, production and engineering data.data in preparing reserve estimates. The extent, quality and reliability of this data can vary.vary which in turn can affect our ability to model the porosity, permeability and pressure relationships in unconventional resources. The process also requires economic assumptions, based on historical data but projected into the future, about matters such as crude oil and natural gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds.

The prices used in calculating our estimated proved reserves are calculated by determining the unweighted arithmetic average of the first-day-of-the-month commodity prices for the preceding 12 months. For the year ended December 31, 2015, average prices used to calculate our estimated proved reserves were $50.28 per Bbl for crude oil and $2.58 per MMBtu for natural gas ($41.63 per Bbl for crude oil and $2.35 per Mcf for natural gas adjusted for location and quality differentials). Actual future prices may materially differ from those used in our year-end estimates.
Crude oil prices existing in February 2016 are significantly lower than the 2015 average price used to determine our year-end proved reserves. If crude oil prices do not increase significantly, our future calculations of estimated proved reserves will be based on lower prices which could result in our having to remove non-economic reserves from our proved reserves in future periods. Holding all other factors constant, if crude oil prices used in our year-end reserve estimates were decreased by $15.00 per barrel, thereby approximating the pricing environment existing in February 2016, our proved reserves at December 31, 2015 could decrease by approximately 146 MMBoe, or 12%. See Part I, Item 1. Business—Crude Oil and Natural Gas Operations—Proved Reserves—Proved Reserve and PV-10 Sensitivities for additional proved reserve sensitivities under various commodity price scenarios.
Actual future production, crude oil and natural gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable crude oil and natural gas reserves will vary and could vary significantly from our estimates. Any significant variance could materially affect the estimated quantities and present value of our reserves.reserves, which in turn could have an adverse effect on the value of our assets. In addition, we may adjust estimates of proved reserves, potentially in material amounts, to reflect production history, results of exploration and development activities, prevailing crude oil and natural gas prices and other factors, many of which are beyond our control.

The present value of future net revenues from our proved reserves will not necessarily be the same as the current market value of our estimated crude oil and natural gas reserves.

You should not assume the present value of future net revenues from our proved reserves is the current market value of our estimated crude oil and natural gas reserves. In accordance with SEC rules, weWe base the estimated discounted future net revenues from proved reserves on the 12-month unweighted arithmetic average of the first-day-of-the-month commodity prices for the preceding twelve months. Actual future prices may be materially higher or lower than the average prices used in the calculations. Actual future net revenues from crude oil and natural gas properties will be affected by factors such as:

the actual cost and timing of development and production expenditures;

the amount and timing of actual production;

the actual prices we receive for sales of crude oil and natural gas;

the actual cost and

timing of development and production expenditures;

the timing and amount of actual production; and

changes in governmental regulations or taxation.

The timing of both our production and our incurrence of expenses in connection with the development and production of crude oil and natural gas properties will affect the timing and amount of actual future net revenues from proved reserves, and thus their actual present value. In addition, the use of a 10% discount factor, we use when calculating which is required by the SEC to be used to calculate

31



discounted future net revenues for reporting purposes, may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with our reserves or the crude oil and natural gas industry in general.

At December 31, 2015, the PV-10 value of our proved reserves totaled approximately $8.0 billion. The average prices used to estimate our proved reserves and PV-10 at December 31, 2015 were $50.28 per Bbl for crude oil and $2.58 per MMBtu for natural gas ($41.63 per Bbl for crude oil and $2.35 per Mcf for natural gas adjusted for location and quality differentials).

SensitivitiesOur use of enhanced recovery methods creates uncertainties that could adversely affect our results of operations and financial condition.

One of our business strategies is to commercially develop unconventional crude oil and natural gas resource plays using enhanced recovery technologies. For example, we inject water and high-pressure air into formations on some of our properties to increase the production of crude oil and natural gas. The for additional production and reserves attributable to the use of these enhanced recovery methods are inherently difficult to predict. If enhanced recovery programs do not allow for the extraction of crude oil and natural gas in the manner or to the extent we anticipate, our future results of operations and financial condition could be materially adversely affected.

If crude oil and natural gas prices decrease, wePV-10 sensitivities under various commodity price scenarios.

We may be required to further write down the carrying values of our crude oil and natural gas properties.

properties if commodity prices remain at their currently low levels or decline further.

Accounting rules require that we periodically review the carrying values of our crude oil and natural gas properties for possible impairment. Proved properties are reviewed for impairment on a field-by-field basis each quarter. We use the successful efforts method of accounting whereby the estimated future cash flows expected in connection with a field are compared to the carrying amount of the field to determine if the carrying amount is recoverable. If the carrying amount of the field exceeds its estimated undiscounted future cash flows, the carrying amount of the field is reduced to its estimated fair value using a discounted cash flow model.
Based on specific market factors, prices, and circumstances at the time of prospective impairment reviews, and the continuing evaluation of development plans, production data, economics and other factors, we may be required to write down the carrying values of our crude oil and natural gas properties. A write-down constitutesresults in a non-cash charge to earnings. We may incurhave incurred impairment charges in the past and may incur additional impairment charges in the future, particularly if commodity prices remain at their currently low levels or decline further, which could have a material adverse effect on our results of operations for the periods in which such charges are taken.

Unless we replace our crude oil and natural gas reserves, our reserves and production will decline, which could adversely affect our cash flows and results of operations.

Unless we conduct successful exploration, development and exploitation activities or acquire properties containing proved reserves, our proved reserves will decline as those reserves are produced. Producing crude oil and natural gas reservoirs are generally characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Our future crude oil and natural gas reserves and production, and therefore our cash flows and results of operations, are highly dependent on our success in efficiently developing our current reserves and economically finding or acquiring additional recoverable reserves. We may not be able to develop, find or acquire sufficient additional reserves to replace our current and future production. If we are unable to replace our current and future production, the value of our reserves will decrease, and our business, financial condition and results of operations could be materially adversely affected.

The unavailability or high cost of additional drilling rigs, equipment, supplies, personnel and oilfield services could adversely affect our ability to execute our exploration and development plans within budget and on a timely basis.

Shortages or

In the high costregions in which we operate, there have historically been shortages of drilling rigs, equipment, supplies, personnel or oilfield services, including key components used in fracture stimulation processes such as water and proppants, as well as high costs associated with these critical components of our operations. As a result of the significant decrease in commodity prices, the number of providers of the materials and services described above has decreased in the regions where we operate. As a result, the likelihood of experiencing shortages or higher costs of materials and services may be increased in connection with any period of commodity price recovery. Such shortages or high costs could delay the execution of our drilling plans or cause us to incur significant expenditures not provided for in our capital budget, which could have a material adverse effect on our business, financial condition, or results of operations.

We may incur substantial losses and be subject to substantial liability claims as a result of our crude oil and natural gas operations. Additionally, we may not be insured for, or our insurance may be inadequate to protect us against, these risks.

We are not insured against all risks. Losses and liabilities arising from uninsured and underinsuredunder-insured events could materially and adversely affect our business, financial condition or results of operations. Our crude oil and natural gas exploration and production activities are subject to all of the operating risks associated with drilling for and producing crude oil and natural gas, including the possibility of:

environmental hazards, such as uncontrollable flows of crude oil, natural gas, brine, well fluids, hydraulic fracturing fluids, toxic gas or other pollutants into the environment, including groundwater and shoreline contamination;

abnormally pressured formations;

mechanical difficulties, such as stuck oilfield drilling and service tools and casing collapse;

fires, explosions and ruptures of pipelines;

loss of product or property damage occurring as a result of transfer to a rail car or train derailments;

personal injuries and death;

adverse weather conditions and natural disasters; and

spillage or mishandling of crude oil, natural gas, brine, well fluids, hydraulic fracturing fluids, toxic gas or other pollutants by us or by third party service providers.

Any of these risks could adversely affect our ability to conduct operations or result in substantial losses to us as a result of:

injury or loss of life;

damage to andor destruction of property, natural resources and equipment;

pollution and other environmental damage;

regulatory investigations and penalties;

suspension of our operations; and

repair and remediation costs.

costs; and

litigation.
We may elect not to obtain insurance if we believe the cost of available insurance is excessive relative to the risks presented. In addition, pollution and environmental risks are generally are not fully insurable. The occurrence of an event that is not fully covered by insurance could have a material adverse effect on our business, financial condition, and results of operations.

Prospects we decide to drill may not yield crude oil or natural gas in economically producible quantities.

Prospects we decide to drill that do not yield crude oil or natural gas in economically producible quantities may adversely affect our results of operations and financial condition. In this report, we describe some of our current prospects and plans to explore and develop those prospects. Our prospects are in various stages of evaluation, ranging from a

prospect which is ready to drill to a prospect that will requirerequiring substantial additional seismic data processing and interpretation. It is not possible to predict with certainty in advance of drilling and testing whether any particular prospect will yield crude oil or natural gas in sufficient quantities to recover drilling or completion costs or be economically producible. The use of seismic data and other technologies and the study of producing fields in the same area will not enable us to know conclusively prior to drilling whether crude oil or natural gas will be present or, if present, whether crude oil or natural gas will be present in economically producible quantities. We cannot assure you that the analogies we draw from available data from other wells, more fully explored prospects or producing fields will be applicable to our drilling prospects.

Our identified drilling locations are scheduled out over several years, making them susceptible to uncertainties that could materially alter the occurrence or timing of their drilling.

Our management has specifically identified and scheduled drilling locations as an estimation of our future multi-year drilling activities on our existing acreage. These drilling locations represent a significant part of our growth strategy. Our ability to drill and develop these locations depends onis subject to a number of uncertainties, including crude oil and natural gas prices, the availability of capital, costs, drilling results, regulatory approvals, available transportation capacity, and other factors. If future drilling results in these projects do not establish sufficient reserves to achieve an economic return, we may curtail drilling in these projects. Because of these uncertainties, we do not know if the numerous potential drilling locations we have identified will ever be drilled or if we will be able to produce crude oil or natural gas from these or any other

33



potential drilling locations.locations in sufficient quantities to achieve an economic return. In addition, unless production is established within the spacing units covering the undeveloped acres on which some of the locations are identified, the leases for such acreage will expire. IfCurrently low commodity prices, reduced capital spending and numerous other factors, many of which are beyond our control, could result in our failure to establish production on undeveloped acreage, and, if we are not able to renew leases before they expire, any proved undeveloped reserves associated with such leases will be removed from our proved reserves. The combined net acreage expiring in the next three years represents 65%60% of our total net undeveloped acreage at December 31, 2012.2015. At that date, we had leases representing 359,999320,188 net acres expiring in 2013, 234,2972016, 283,590 net acres expiring in 2014,2017, and 279,486112,478 net acres expiring in 2015.2018. Our actual drilling activities may materially differ from those presently identified, which could adversely affect our business.

The development of our proved undeveloped reserves may take longer and may require higher levels of capital expenditures than we currently anticipate. Our proved undeveloped reserves may not be ultimately developed or produced.
At December 31, 2015, approximately 57% of our total estimated proved reserves (by volume) were undeveloped and may not be ultimately developed or produced. Recovery of undeveloped reserves requires significant capital expenditures and successful drilling operations. Our reserve estimates assume we can and will make these expenditures and conduct these operations successfully. These assumptions may not prove to be accurate. Our reserve report at December 31, 2015 includes estimates of total future development costs over the next five years associated with our proved undeveloped reserves of approximately $6.5 billion. We cannot be certain the estimated costs of the development of these reserves are accurate, development will occur as scheduled, or the results of such development will be as estimated. If we choose not to spend the capital to develop these reserves, or if we are not otherwise able to successfully develop these reserves as a result of our inability to fund necessary capital expenditures or otherwise, we will be required to remove the associated volumes from our reported proved reserves. In addition, under the SEC’s reserve rules, because proved undeveloped reserves may be booked only if they relate to wells scheduled to be drilled within five years of the date of booking, we may be required to remove any proved undeveloped reserves not developed within this five-year time frame. Such removals have occurred in the past and may occur in the future. A removal of such reserves could adversely affect our operations. In 2015, 98 MMBoe of proved undeveloped reserves were removed from our year-end reserve estimates due to various factors, including removals associated with drilling locations no longer scheduled to be developed within five years from the date of initial booking. Additionally, decreases in commodity prices in 2015 caused certain exploration and development projects to become uneconomic, which resulted in downward revisions of proved undeveloped reserves totaling 181 MMBoe in 2015.
Our business depends on crude oil and natural gas transportation, processing and refining facilities, most of which are owned by third parties, and on the availability of rail transportation

transportation.

The marketability ofvalue we receive for our crude oil and natural gas production depends in part on the availability, proximity and capacity of pipeline and rail systems and processing and refining facilities owned by third parties. The lackinadequacy or unavailability of capacity on these systems and facilities could result in the shut-in of producing wells or the delay, or discontinuance of, development plans for properties. Although we have some contractual control over the transportation of our product, materialproducts, changes in these business relationships could materially affect our operations. Federal and state regulation of crude oil and natural gas production and transportation, tax and energy policies, changes in supply and demand, pipeline pressures, damageor failure to or destruction of pipelines and rail systems, labor disputes and general economic conditionsobtain such services on acceptable terms could adversely affect our abilityoperations. If our production becomes shut-in for any of these or other reasons, we would be unable to produce, gather, transport and sell crude oil and natural gas. As a result of pipeline constraints,realize revenue from those wells until other arrangements were made for the continuous increase in Williston Basin production, and our desire to transport our crude oil to coastal markets which currently provide the most favorable pricing, in December 2012 we transported approximately 72%sale or delivery of our operated crude oil production from the Bakken field by rail.

We have no control over when or if access to such pipeline or rail facilities would be restored or whatthe impact on prices would be charged.in the areas we operate. A significant shut-in of production in connection with any of the aforementioned items could materially affect our cash flows, and if a substantial portion of the impacted production is hedged at lower than market prices, those financial hedges would have to be paid from borrowings absent sufficient cash flows.

We transport a portion of the operated crude oil production from our North region to market centers using rail transportation facilities owned and operated by third parties, with approximately 17% of such production being shipped by rail in December 2015. See Part I, Item 1. Business—Regulation of the Crude Oil and Natural Gas Industry—Regulation of sales and transportation of crude oil and natural gas liquids for a discussion of regulations impacting the transportation of crude oil by rail. Compliance with regulations, including voluntary measures adopted by the railroad industry, impacting the type, design, specifications or construction of rail cars used to transport crude oil could result in severe transportation capacity constraints during the period in which new rail cars are retrofitted or constructed to meet specifications. We do not currently own or operate rail transportation facilities or rail cars; however, compliance with regulations that impact the testing or rail

transportation of crude oil could increase our costs of doing business and limit our ability to transport and sell our crude oil at market centers throughout the United States, the consequences of which could have a material adverse effect on our financial condition, results of operations and cash flows.
Our business depends on the availability of water and the ability to dispose of waste water from oil and gas activities. Limitations or restrictions on our ability to obtain or dispose of water may have an adverse effect on our financial condition, results of operations and cash flows.
With current technology, water is an essential component of drilling and hydraulic fracturing processes. Limitations or restrictions on our ability to secure sufficient amounts of water, or to dispose of or recycle water after use, could adversely impact our operations. In some cases, water may need to be obtained from new sources and transported to drilling sites, resulting in increased costs. Moreover, the introduction of new environmental initiatives and regulations related to water acquisition or waste water disposal, including produced water, drilling fluids and other wastes associated with the exploration, development or production of hydrocarbons, could limit or prohibit our ability to utilize hydraulic fracturing or waste water injection wells.
In addition, concerns have been raised about the potential for seismic events to occur from the use of underground injection wells, a predominant method for disposing of waste water from oil and gas activities. New rules and regulations may be developed to address these concerns, possibly limiting or eliminating the ability to use disposal wells in certain locations and increasing the cost of disposal. We operate injection wells and utilize injection wells owned by third parties to dispose of waste water associated with our operations. Some states, including states in which we operate, have delayed permit approvals, mandated a reduction in injection volumes, or have shut down or imposed moratoria on the use of injection wells. Regulators in some states, including states in which we operate, are considering additional requirements related to seismic safety. For example, in Oklahoma, the Oklahoma Corporation Commission ("OCC") has adopted rules for operators of saltwater disposal wells in certain seismically-active areas in the Arbuckle formation of the state. These rules require disposal well operators, among other things, to conduct mechanical integrity testing or make certain demonstrations of such wells’ respective depths that, depending on the depth, could require plugging the well and/or the reduction of volumes disposed in such wells. Oklahoma has adopted a “traffic light” system, wherein the OCC reviews new or existing disposal wells for proximity to faults, seismicity in the area and other factors in determining whether such wells should be permitted, permitted only with special restrictions, or not permitted.
Compliance with existing or new environmental regulations and permit requirements governing the withdrawal, storage, and use of water necessary for hydraulic fracturing of wells or the disposal of waste water may increase our operating costs or may cause us to delay, curtail or discontinue our exploration and development plans, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.
We have been an early entrant into new or emerging plays. As a result, our drilling results in these areas are uncertain, and the value of our undeveloped acreage will decline if drilling results are unsuccessful.

While our costs to acquire undeveloped acreage in new or emerging plays have generally been less than those of later entrants into a developing play, our drilling results in thesenew or emerging areas are more uncertain than drilling results in developed and producing areas. Since new or emerging plays have limited or no production history, we are unable to use past drilling results in those areas to help predict our future drilling results. As a result, our cost of drilling, completing and operating wells in these areas may be higher than initially expected, and the value of our undeveloped acreage will decline if drilling results are unsuccessful.

We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities.

Our crude oil and natural gas exploration and production operations are subject to complex and stringent federal, state and local laws and regulations.regulations, including those governing environmental protection, the occupational health and safety aspects of our operations, the discharge of materials into the environment, and the protection of certain plant and animal species. See Part I, Item 1. Business—Regulation of the Crude Oil and Natural Gas Industry for a description of the laws and regulations that affect us. In order to conduct operations in compliance with these laws and regulations, we must obtain and maintain numerous permits, approvals and certificates from various federal, state and local governmental authorities. WeEnvironmental regulations may incurrestrict the types, quantities and concentration of materials released into the environment in connection with drilling and production activities, limit or prohibit drilling activities on certain lands lying within wilderness, wetlands and other protected areas, and impose substantial costs in order to maintain compliance with these existing laws and regulations.liabilities for pollution resulting from our operations. In addition, we may experience delays in obtaining or be unable to obtain required permits, which may delay or interrupt our costs of compliance may increase if existing lawsoperations and regulations are revised or reinterpreted, or if new lawslimit our growth and regulations become applicable to our operations.

Climate change legislation or regulations governing the emissions of “greenhouse gases” could result in increased operating costs and reduce demand for the crude oil, natural gas and natural gas liquids we produce.

On December 15, 2009, the

In response to EPA published its findings that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment toendanger human health and the environment, because emissions of such gases are, according to the EPA contributing to the warming of the Earth’s atmosphere and other climate changes. These findings by the EPA allow the agency to proceed with the adoption and implementation of severalhas adopted regulations that would restrict emissions of greenhouse gases under existing provisions of the federal Clean Air Act such as the so-called “tailoring rule” adopted in May 2010, which imposes permittingestablishing, among other things, Prevention of Significant Deterioration ("PSD") and bestconstruction and Title V operating permit reviews for certain large stationary sources. Facilities required to obtain PSD permits for greenhouse gas emissions are also required to meet “best available control technology requirementstechnology” standards established on a case-by-case basis. We currently do not have any facilities that are required to adhere to the largest greenhouse gas stationary sources. In November 2010,PSD or Title V permit requirements; however, attempts by the EPA also finalized its greenhouse gas reporting requirements for certainto aggregate multiple oil and gas production facilities, that emit 25,000 metric tons each of which is currently and has long been regarded as an individual stationary source, for permitting purposes could result in the aggregate emissions from these independent facilities triggering Title V and/or more of carbon dioxide equivalent per year. The rule requires annual reportingPSD requirements. EPA rulemakings related to greenhouse gas emissions could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources.
In addition, the EPA has adopted rules requiring the monitoring and reporting of greenhouse gas emissions by such regulated facilities.

On April 17, 2012,from specified onshore and offshore oil and gas production sources in the United States on an annual basis, which include certain of our operations. In August 2015, the EPA issued final rules that establishedproposed new airregulations setting methane emission controlsstandards for crudenew and modified oil and natural gas production and natural gas processing operations. These rules were publishedand transmission facilities as part of the Obama Administration’s efforts to reduce methane emissions from the oil and gas sector by up to 45% from 2012 levels by 2025. The proposed regulations are expected to be finalized in 2016. On January 22, 2016, the Federal RegisterBureau of Land Management issued a pre-publication version of a proposed venting and flaring rule, which is expected to be finalized in 2016 and, like the forthcoming EPA regulations, will address methane emissions from crude oil and natural gas sources. Recently, the EPA has increased the level of Clean Air Act enforcement activity within the upstream oil and gas sector, focusing on

August 16, 2012. The EPA’s rule package includes New Source Performance Standards alleged violations related to address emissions of sulfur dioxidegreenhouse gases and volatile organic compounds (“VOCs”) from production facilities.  To the extent the EPA experiences success in connection with enforcement efforts in a given geographical area, it may decide to extend such efforts to additional areas, including those where we have significant operations. The EPA may also choose to focus its initial efforts with respect to any new enforcement initiative on an area where we have significant operations. 

In December 2015, a global climate agreement was reached in Paris at the 21st Conference of Parties organized by the United Nations under the Framework Convention on Climate Change. The agreement, which goes into effect in 2020, resulted in nearly 200 countries, including the United States, committing to work towards limiting global warming and agreeing to a separate setmonitoring and review process of emission standardsgreenhouse gas emissions. The agreement includes binding and non-binding elements and did not require ratification by the U.S. Congress. Nonetheless, the agreement may result in increased political pressure on the United States to address hazardous air pollutants frequently associatedensure continued compliance with crude oilenforcement measures under the Clean Air Act and naturalmay spur further initiatives aimed at reducing greenhouse gas production and processing activities. The final rules require the use of reduced emission completions or “green completions” on all hydraulically-fractured wells completed or refractured after January 1, 2015 in order to achieve a 95 percent reductionemissions in the emission of VOCs. The rules also establish specific new requirements regarding emissions from compressors, controllers, dehydrators, storage tanks and other production equipment. These rules may require modifications to our operations, including the installation of new equipment to control emissions from our wells by January 1, 2015. Compliance with such rules could result in significant costs, including increased capital expenditures and operating costs, and could adversely impact our business.

In addition, the U.S.future.

While Congress has from time to time considered legislation to reduce emissions of greenhouse gases, and almost halfthere has not been significant activity in the form of the states, including states in which we operate, have enacted or passed measuresadopted legislation to reduce greenhouse gas emissions at the federal level in recent years. In the absence of such federal legislation, a number of state and regional efforts have emerged that are aimed at tracking and reducing greenhouse gases, primarily through the planned developmentgas emissions by means of cap and trade programs that typically require major sources of greenhouse gas emission inventories and/or regional greenhouse gas cap-and-trade programs. Most of these cap-and-trade programs work by requiring either major sources of emissions, or major producers of fuelssuch as electric power plants, to acquire and surrender emission allowances with the number of allowances availablein return for purchase reduced each year until the overallemitting greenhouse gas emission reduction goal is achieved. These reductions may cause the cost of allowances to escalate significantly over time.

The adoption and implementation of regulations that require reporting of greenhouse gases or otherwise limit emissions of greenhouse gases from our equipment and operations could require us to incur costs to monitor and report on greenhouse gas emissions or install new equipment to reduce emissions of greenhouse gases associated with our operations. In addition, these regulatory initiativessubstantial limitations on greenhouse gas emissions could drive downadversely affect the demand for our products by stimulating demand for alternative forms of energy that do not rely on combustion of fossil fuels that serve as a major source of greenhousethe crude oil and natural gas emissions,we produce, which could have a material adverse effect on our business, financial condition, and results of operations.

Finally, it should be noted some scientists have concluded that increasing concentrations of greenhouse gases in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, floods andor other climatic events. If any such effects were to occur as a result of climate change or otherwise, they could have an adverse effect on our assets and operations.

Federal and state legislation and regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional operating restrictions or delays and inability to book future reserves.

A significant majority of our operations utilize hydraulic

Hydraulic fracturing is an important and commonly used process in the completion of crude oil and natural gas wells in low-permeability formations. Hydraulic fracturing involves the high-pressure injection of water, sand and additives into rock formations to stimulate crude oil and natural gas production. Some activists have attempted to linkIn recent years there has been increased public concern regarding an alleged potential for hydraulic fracturing to various environmental problems, including adverse effects toadversely affect drinking water supplies as well as migration of methane and other hydrocarbons.to induce seismic events. As a result, several federal and state agencies are studying potential environmental risks with respectconsidering legislation that would increase the regulatory burden imposed on hydraulic fracturing.
At the federal level, the EPA has asserted federal regulatory authority pursuant to hydraulic fracturing or evaluating whether to restrict its use. From time to time legislation has been introduced in the U.S. Congress to amend the federal Safe Drinking Water Act to eliminate an existing exemption for("SDWA") over certain hydraulic fracturing activities frominvolving the definitionuse of “underground injection,” thereby requiringdiesel fuels and published permitting guidance in February 2014 related to such activities. In May 2014, the crude oil and natural gas industryEPA issued an Advance Notice of Proposed Rulemaking to obtain permits for hydraulic fracturing, and to require disclosure of the additives used in the process. If ever adopted, such legislation could establish an additional level of regulation and permitting at the federal level. Scrutiny of hydraulic fracturing activities continues in other ways. The White House Councilcollect data on Environmental Quality is coordinating an administration-wide review of hydraulic fracturing practices, and a number of federal agencies are analyzing environmental issues associated with hydraulic fracturing. The EPA has commenced a multi-year study of the potential environmental impacts of hydraulic fracturing, the draft results of which are anticipated to be available by 2014. Further, on May 11, 2012, the BLM issued a proposed rule that would require public

disclosure of chemicals used in hydraulic fracturing operations and imposeunder Section 8 of the Toxic Substances Control Act. To date, no other operational requirements for allaction has been taken. Further, in April 2015 the EPA issued proposed regulations under the Clean Water Act governing discharges to publicly owned treatment works of waste water from hydraulic fracturing operationsand certain other natural gas operations. Moreover, in 2015 the EPA completed a study of the potential impacts of hydraulic fracturing activities on water resources and published a draft assessment in June 2015 for peer review and public comment. In its assessment, the EPA indicated it did not find evidence that hydraulic fracturing mechanisms caused widespread, systemic impacts on drinking water resources in the United States. Nonetheless, the results of the study or similar governmental reviews could spur initiatives to regulate hydraulic fracturing under the SDWA or otherwise. Finally, the U.S. Department of Interior issued final rules in March 2015 related to the regulation of hydraulic fracturing activities on federal lands, including Native American trust lands.requirements for chemical disclosure, well bore integrity and handling of flowback water. The DepartmentU.S. District Court of the Interior announced on January 18, 2013 that BLM will issueWyoming has temporarily stayed implementation of this rule and a revised draft rule by March 31, 2013. Atfinal decision remains pending. As of December 31, 2012,2015, we held approximately 79,400181,500 net undeveloped acres on federal land, representing approximately 6%15% of our total net undeveloped acres. In addition to these federal initiatives,


At the state level, several state and local governments,states, including states in which we operate, have movedadopted or are considering adopting legal requirements imposing more stringent permitting, disclosure, and well construction requirements on hydraulic fracturing activities. Local governments also may seek to require disclosureadopt ordinances within their jurisdictions regulating the time, place and manner of drilling activities in general or hydraulic fracturing fluid componentsactivities in particular or to otherwise regulate their use more closely.prohibit the performance of well drilling in general or hydraulic fracturing in particular. In certain areas of the United States, new drilling permits for hydraulic fracturing have been put on hold pending development of additional standards.

The adoption of any future federal, state or local law or implementing regulation imposing permitting or reporting obligations on, or otherwise limiting, the hydraulic fracturing process, or the discovery of groundwater contamination or other adverse environmental effects directly connected to hydraulic fracturing, could make it more difficult and more expensive to complete crude oil and natural gas wells in low-permeability formations and increase our costs of compliance and doing business, as well as delay, prevent or prohibit the development of natural resources from unconventional formations. In the event regulations are adopted thatto prohibit or significantly limit the use of hydraulic fracturing in states in which we operate, it would have a material adverse effect on our ability to economically find and develop crude oil and natural gas reserves in our strategic plays. The inability to achieve a satisfactory economic return could cause us to curtail or discontinue our exploration and development plans. Such a circumstanceplans, which would have a material adverse effect on our business, financial condition, results of operations and would impair our ability to implement our growth plan.

Should we fail to comply with FERC, FTC and CFTC administered statutes and regulations on market behavior, we could be subject to substantial penalties and fines and other liabilities.

The FERC, under the EPAct 2005, and the FTC, under the Independence and Security Act of 2007, may impose or seek to impose through judicial action penalties for violations of anti-market manipulation rules for natural gas, crude oil and petroleum products of up to $1,000,000 per day for each violation. The CFTC, under the Commodity Exchange Act, has similar authority to impose penalties of up to $1,000,000 or triple the monetary gain for violation of anti-market manipulation rules for certain derivative contracts. In addition, while we have not been regulated by the FERC as a natural gas company under the NGA, the FERC has adopted regulations that may subject us to the FERC annual reporting requirements. Additional rules and legislation pertaining to those and other matters may be considered or adopted by the FERC, the FTC or CFTC from time to time. Failure to comply with any of these regulations in the future could subject us to civil penalty liability, as well as the disgorgement of profits and third-party claims.

Proposed legislation and regulationregulations under consideration could increase our operating costs, reduce our liquidity, delay our operations or otherwise alter the way we conduct our business.

Our operations are subject to extensive federal, state and local laws and regulations. 

Changes to existing laws or regulations, new laws or regulations, or changes in interpretations of laws and regulations may unfavorably impact us or the infrastructure used for transporting our products. Similarly, changes in regulatory policies and priorities could result in the imposition of new obligations upon us, such as increased reporting or audits. Any of these requirements could result in increased operating costs and could have a material adverse effect on our financial condition and results of operations. If such legislation, regulationregulations or other requirements are adopted, they could result in, among other items, additional limitations and restrictions on hydraulic fracturing of wells, restrictions on the disposal of waste water from oil and gas activities, restrictions on emissions of greenhouse gases, changes to the calculation of royalty payments, new safety requirements such as those involving rail transportation, and additional regulation of private energy commodity derivative and hedging activities. These and other potential laws, regulations and other requirements could increase our operating costs, reduce our

Future legislation may impose new taxes on crude oil or natural gas activities, including by eliminating or reducing certain federal income tax deductions currently available with respect to crude oil and natural gas exploration and development may be eliminated as a result of future legislation.

Among thedevelopment.

In recent years, legislation has been proposed to make significant changes contained in President Obama’s fiscal year 2013 budget proposal areto U.S. federal income tax laws, including the elimination or deferral of certain key U.S. federal income tax deductions currently available to crude oil and natural gas exploration and production companies. Such proposed changes include, but are not limited to,to: (i) the repeal of the percentage depletion allowance for crude oil and natural gas properties; (ii) the elimination of current deductions for intangible drilling and exploration and development costs; (iii) the elimination of the deduction for certain production activities; and (iv) an extension of the amortization period for certain geological and geophysical expenditures.

Additionally, President Obama has proposed, as part of the Budget of the United States Government for capital expendituresFiscal Year 2017, to impose an “oil fee” of $10.25 per barrel equivalent of crude oil.  This fee would be collected on domestically produced and imported petroleum products.  If enacted into law, the fee would be phased in over five years, beginning October 1, 2016.  The adoption of this, or similar proposals, could result in increased operating costs and/or reduced consumer demand for petroleum products, which in turn could affect the prices companies such as ours receive for our ability to achieve our growth plan.

Regulations under the Dodd-Frank Act regarding derivatives could have an adverse effect on our ability to use derivative instruments to reduce the effect of commodity price risk and other risks associated with our business.

We

From time to time, we may use derivative instruments to manage our commodity price risk. In 2010, the U.S. Congress adopted the Dodd-Frank Act, which, among other provisions, establishes federal oversight and regulation of the over-the-counter derivatives market and entities, such as us, that participate in that market. This financial reform legislation includes provisions that require many derivative transactions that are currentlypreviously executed over-the-counter to be executed through an exchange and be centrally cleared. The newIn addition, this legislation was signed into law by President Obama on July 21, 2010 and requires the CFTC, the SEC, and in some cases banking regulators, to promulgate rules and regulations implementing the new legislation. The CFTC has issued final regulations to implement significant aspects of the legislation, including new rulescalls for the registrationimposition of position limits for swaps, including swaps involving physical commodities such as crude oil and natural gas, which have been proposed but have not been finalized. It also establishes minimum margin requirements for uncleared swaps for swap dealers and major swap participants (and related definitions of those terms), definitions of the term “swap,” rules to establish the ability to rely on the commercial end-user exception from the central clearing and exchange trading requirements, requirements for reporting and recordkeeping, rules on customer protection in the context of cleared swaps, and position limits for swaps and other transactions based on the price of certain reference contracts, some of which are referenced in our swap contracts. Key regulations that have not yet been finalized include those establishing margin requirements for uncleared swaps, regulatory capital requirements for swap dealers and various trade execution requirements.

On December 13, 2012, the CFTC published final rules regarding mandatory clearing of certain interest rate swaps and certain index credit default swaps and setting compliance dates for different categories of market participants, the earliest of which is March 11, 2013. The CFTC has not yet proposed any rules requiring the clearing of any other classes of swaps, including physical commodity swaps.participants. If we do not qualify for the end-userend user exception from theany clearing requirement forrequirements applicable to our swaps, the mandatory clearing requirements and revised capital requirements applicable to other market participants, such as swap dealers, may change the cost and availability of the swaps we use for hedging.managing commodity price risk. Some of the counterparties to our derivative instruments may also need or choose to spin off some of their derivativesderivative activities to a separate entity, which may not be as creditworthycredit-worthy as our current counterparty.

The new legislation and any

Further, if we do not qualify for the end user exemption, the new regulations could significantly increase the cost of derivative contracts, (including through requirements to post collateral, which could adversely affect our available liquidity), materially alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks we encounter, reduce our ability to monetize or restructure existing derivative contracts, lead to fewer potential counterparties, impose new recordkeeping and documentation requirements, and increase our exposure to less creditworthy counterparties. IfThe proposed position limits may limit our ability to implement price risk management strategies if we reduceare not able to qualify for any exemption from such limits. Additionally, if we do not qualify for the end user exemption, the margin requirements for uncleared swaps may require us to post collateral, which could adversely affect our available liquidity. If our use of derivatives becomes limited as a result of the legislation and regulations, our results of operations may become more volatile and our cash flows may be less predictable. Finally, the legislation was intended, in part, to reduce the volatility of crude oil and natural gas prices, which some

legislators attributed to speculative trading in derivatives and commodity instruments related to crude oil and natural gas. Our revenues could therefore be adversely affected if a consequence of the legislation and regulations is to lower commoditycrude oil or natural gas prices. Any of these consequences could have a material adverse effect on our financial position, and results of operations.

Competition in the crude oil and natural gas industry is intense, making it more difficult for us to acquire properties, market crude oil and natural gas and secure trained personnel.

Our ability to acquire additional prospects and to find and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment for acquiring properties, marketing crude oil and natural gas and securing trained personnel. Also, there is substantial competition for capital available for investment in the crude oil and natural gas industry. Certain of our competitors may possess and employ financial, technical and personnel resources greater than ours. Those companies may be able to pay more for productive crude oil and natural gas

properties and exploratory prospects and to evaluate, bid for and purchase a greater number of properties and prospects than our financial or personnel resources permit. In addition, companies may be able to offer better compensation packages to attract and retain qualified personnel than we are able to offer. The cost to attract and retain qualified personnel has increased in recent years due to competition and may increase substantially in the future. We may not be able to compete successfully in the future in acquiring prospective reserves, developing reserves, marketing hydrocarbons, attracting and retaining quality personnel and raising additional capital, which could have a material adverse effect on our financial condition, and results of operations.

Energy conservation measures or initiatives that stimulate demand for alternative forms of energy could reduce the demand for the crude oil and natural gas we produce.
Fuel conservation measures, climate change initiatives, governmental requirements for renewable energy resources, increasing consumer demand for alternative forms of energy, and technological advances in fuel economy and energy generation devices could reduce demand for the crude oil and natural gas we produce. The potential impact of changing demand for crude oil and natural gas services and products may have a material adverse effect on our business, financial condition, results of operations and cash flows.
The loss of senior management or technical personnel could adversely affect our operations.

We depend on the services of our senior management and technical personnel. The loss of the services of our senior management or technical personnel, including Harold G. Hamm, our Chairman and Chief Executive Officer, could have a material adverse effect on our operations. We do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals.

We have limited control over the activities on properties we do not operate.

Some of the properties in which we have an ownership interest are operated by other companies and involve third-party working interest owners. As of December 31, 2012,2015, non-operated properties represented 18%20% of our estimated proved developed reserves, 13%9% of our estimated proved undeveloped reserves, and 15%13% of our estimated total proved reserves. We have limited ability to influence or control the operationoperations or future development of suchnon-operated properties, including compliance with environmental, safety and other regulations, or the amount of capital expenditures required to fund the development and operation of such properties.

Our revolving credit facility, three-year term loan, and the indentures for our senior notes contain certain covenants and restrictions that may inhibit our ability to make certain investments, incur additional indebtedness and engage in certain other transactions, which could adversely affect our ability to meet our future goals.

Our revolving credit facility and the indentures for our senior notes include certainthree-year term loan contain restrictive covenants and restrictions that among others, restrict:

our investments, loans and advances and the paying of dividends and other restricted payments;

our incurrence of additional indebtedness;

the granting of liens, other than liens created pursuant to the revolving credit facility and certain permitted liens;

mergers, consolidations and sales of all or a substantial part of our business or properties;

the hedging, forward sale or swap of our production of crude oil or natural gas or other commodities; and

the sale of assets.

The indentures for our outstanding senior notes limit our ability and the ability of our restricted subsidiaries to:

Our revolving credit facility and three-year term loan also requires uscontain a requirement that we maintain a consolidated net debt to maintaintotal capitalization ratio of no greater than 0.65 to 1.00. This ratio represents the ratio of net debt (total debt less cash and cash equivalents) divided by the sum of net debt plus total shareholders’ equity plus, to the extent resulting in a reduction of total shareholders' equity, the amount of any non-cash impairment charges incurred, net of any tax effect, after June 30, 2014.

At December 31, 2015, our consolidated net debt to total capitalization ratio, as defined, was 0.58 to 1.00. Our total debt would need to independently increase by approximately $2.6 billion, or 36%, above existing levels at December 31, 2015 (with no corresponding increase in cash or reduction in refinanced debt) to reach the maximum covenant ratio of 0.65 to 1.00. Alternatively, our total shareholders' equity would need to independently decrease by approximately $1.4 billion, or 30%, below existing levels at December 31, 2015 (excluding the after-tax impact of any non-cash impairment charges) to reach the maximum covenant ratio.
The indentures governing our senior notes contain covenants that, among others, limit our ability to create liens securing certain financial ratios, such as leverage ratios.

Increases in interest rates could adversely affect our business.

Our business and operating results can be harmedadversely affected by factors such as the availability, terms of and cost of capital, increases in interest rates, or a reductiondowngrade or other negative rating action with respect to our credit rating. In February 2016, our corporate credit rating was downgraded by S&P and Moody's in response to weakened oil and gas industry conditions and resulting revisions made to rating agency commodity price assumptions. These downgrades will cause the interest rates on our revolving credit ratings. These changes could cause our cost of doing businessfacility borrowings and three-year term loan to increase by 0.250% and 0.125%, respectively, and may limit our ability to pursue acquisition opportunities, reduce cash flows used for drilling and place us at a competitive disadvantage. For example, asAs of February 15, 2013,19, 2016, outstanding variable rate borrowings under our revolving credit facility were $840 millionand three-year term loan totaled $1.33 billion and the impact of a 1% increase in interest rates on this amount of debt would result in increased annual interest expense of approximately $8.4$13.3 million and a $5.2an $8.2 million decrease in our annual net income. We require continued access to capital. A significant reduction in cash flows from operations or the availability of credit could materially and adversely affect our ability to achieve our planned growthfinancial condition and operating results.

The inability of ourjoint interest owners, derivative counterparties, significant customers, and service providers to meet their obligations to us may adversely affect our financial results.

Our principal exposure to credit risk is through the sale of our crude oil and natural gas production, which we market to energy marketing companies, refineriescrude oil refining companies, and affiliatesnatural gas gathering and processing companies ($480.3379 million in receivables at December 31, 2012),2015); our joint interest receivables ($356.8232 million at December 31, 2012),2015); and counterparty credit risk

associated with our derivative instrument receivables ($50.6108 million at December 31, 2012)2015).

Joint interest receivables arise from billing the individuals and entities who own a partial interest in the wells we operate. These individuals and entities participate in our wells primarily based on their ownership in leases included in units on which we wish to drill. We can do very little to choose who participates in our wells.
We are also subject to credit risk due to concentration of our crude oil and natural gas receivables with several significant customers. The largest purchaser of our crude oil and natural gas during the year ended December 31, 20122015 accounted for approximately 21%11% of our total crude oil and natural gas revenues.revenues for the year. We have not generally do not requirerequired our counterparties to provide collateral to supportsecure crude oil and natural gas sales receivables owed to us.

Our derivative activities could result in financial losses or reduce our earnings.

To achieve more predictable cash flows and reduce our exposure to adverse fluctuations in the prices of crude oil and natural gas, from time to time we may enter into derivative instruments for a portion of our crude oil and/or natural gas production, including collars and fixed price swaps.production. SeePart II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Crude Oil and Natural Gas Hedging andPart II, Item 8. Notes to Consolidated Financial Statements—Note 5. Derivative Instrumentsfor a summary of our crude oil and natural gas commodity derivative positions.positions as of December 31, 2015. We do not designate any of our derivative instruments as hedges for accounting purposes and we record all derivative instrumentsderivatives on our balance sheet at fair value. Changes in the fair value of our derivative instrumentsderivatives are recognized in current period earnings. Accordingly, our earnings may fluctuate significantly as a result of changes in crude oil and natural gas prices and resulting changes in the fair value of our derivative instruments.derivatives.

Derivative instruments expose us to the risk of financial loss in certain circumstances, including when:

production is less than the volume covered by the derivative instruments;

the counterparty to the derivative instrument defaults on its contractual obligations; or

there is an increase in the differential between the underlying price in the derivative instrument and actual prices received.

In addition, our derivative arrangements limit the benefit we would receive from increases in the prices for crude oil and natural gas.commodity prices. Our decision on the quantity and price at which we choose to hedge our future production, if any, is based in part on our view of current and future market conditions and our desire to stabilize cash flows necessary for the development of our undeveloped crude oil and natural gas reserves. As partWe may choose not to hedge future production if the pricing environment for certain time periods is not deemed to be favorable. Additionally, we may choose to liquidate existing derivative positions prior to the expiration of their contractual maturities in order to monetize favorable gain positions for the purpose of funding our risk management program, we have hedgedcapital program. Our crude oil sales for future periods are currently unhedged and directly exposed to continued volatility in crude oil market prices, whether favorable or unfavorable. Additionally, a significant portion of our forecasted production. We utilize a combination of derivative contracts based on West Texas Intermediate (“WTI”) crude oil pricing, Inter-Continental Exchange (“ICE”) pricingnatural gas sales for Brent crude oil,future periods are unhedged and Henry Hub pricingdirectly exposed to continued volatility in natural gas market prices, whether favorable or unfavorable.
A limited liability company for natural gas. We believewhich our derivative contracts provide relevant protection from price fluctuations in the U.S. markets where we deliver and sell our production. The pricing for Brent crude oil is believed to be a better reflection of the sales prices realized in certain U.S. market centers. However, in the event Brent prices increase significantly, the prices realized in those U.S. market centers may no longer be reflective of Brent prices. In such a circumstance, we may incur significant realized cash losses upon settling our crude oil derivative instruments. Such losses may be incurred without seeing a corresponding increase in revenues from higher realized prices on our physical sales of crude oil.

Our Chairman and Chief Executive Officer serves as sole manager beneficially owns approximately 68%76% of our outstanding common stock, giving him influence and control in corporate transactions and other matters, including a sale of our Company.

As of December 31, 2012,2015, a limited liability company for which Harold G. Hamm, our Chairman and Chief Executive Officer, serves as sole manager beneficially owned 126,296,891 shares of our outstanding common stock representing approximately 68%76% of our outstanding common shares. As a result, Mr. Hamm ishas control over our controlling shareholderCompany and will continue to be able to control the

As controlling shareholder,Therefore, Mr. Hamm could cause, delay or prevent a change of control of our Company. The interests of Mr. Hamm and the limited liability company for which he serves as sole manager may not coincide with the interests of other holders of our common stock.

We have historically entered into, and may enter into, transactions from time to time with companies affiliated companies controlled bywith Mr. Hamm provide oilfield, gathering and processing, marketing and other services to us. We expect theseif, after an independent review by our Audit Committee, it is determined such transactions will continueare in the futureCompany's best interests and are on terms no less favorable to us than could be achieved with an unaffiliated third party. These transactions may result in conflicts of interest between Mr. Hamm’s affiliated companies and us. We can provide no assurance that any such conflicts will be resolved in our favor.

We may be subject to risks in connection with acquisitions.

The successful acquisition of producing properties requires an assessment of several factors, including:

including but not limited to:

recoverable reserves;

future crude oil and natural gas prices and theirlocation and quality differentials;

the quality of the title to acquired properties;

future development costs, operating costs and property taxes; and

potential environmental and other liabilities.

The accuracy of these assessments is inherently uncertain. In connection with these assessments, we perform a review, of the subject propertieswhich we believe to be generally consistent with industry practices.practices, of the subject properties. Our review will not reveal all existing or potential problems nor will it permit us to become sufficiently familiar with the properties to fully assess their deficiencies and capabilities prior to acquisition. Inspections may not always be performed on every well, and environmental problems are not necessarily observable even when an inspection is undertaken. Even when problems are identified, the seller of the subject properties may be unwilling or unable to provide effective contractual protection against all or part of the problems. We oftensometimes are not entitled to contractual indemnification for environmental liabilities and acquire properties on an “as is” basis.


A cyber incident could result in information theft, data corruption, operational disruption, and/or financial loss.
Our business has become increasingly dependent on digital technologies to conduct day-to-day operations including certain exploration, development and production activities. We depend on digital technology, including information systems and related infrastructure as well as cloud applications and services, to process and record financial and operating data, analyze seismic and drilling information, conduct reservoir modeling and reserves estimation, communicate with employees and business associates, perform compliance reporting and in many other activities related to our business. Our business associates, including vendors, service providers, purchasers of our production, and financial institutions, are also dependent on digital technology.
As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or unintentional events, have also increased. Our technologies, systems, networks, and those of our business associates have been and may continue to be subject to risks as a resultthe target of cyber attacks targetingor information security breaches, which could lead to disruptions in critical systems, unauthorized release of confidential or protected information, corruption of data or other disruptions of our business operations. In addition, certain cyber incidents, such as surveillance, may remain undetected for an extended period.

A cyber attack involving our information systems and related infrastructure, used by theor that of our business associates, could disrupt our business and negatively impact our operations in a variety of ways, including but not limited to:
unauthorized access to seismic data, reserves information, strategic information, or other sensitive or proprietary information could have a negative impact on our ability to compete for oil and gas industry.

Computers control nearly allresources;

data corruption or operational disruption of the crude oil and natural gasproduction-related infrastructure could result in a loss of production, and distribution systems in the U.S. and abroad, some of which are utilized to transport our production to market. Aor accidental discharge;

To our knowledge we have not experienced any material losses relating to cyber attacks; however, there can be no assurance that we will not suffer material losses in the future. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities.

Item 3.Legal Proceedings

In November 2010, an allegeda putative class action was filed in the District Court of Blaine County, Oklahoma by Billy J. Strack and Daniela A. Renner as trustees of certain named trusts and on behalf of other similarly situated parties against the Company allegingCompany. The Petition alleged the Company improperly deducted post-production costs from royalties paid to plaintiffs and other royalty interest owners as categorized in the petition from crude oil and natural gas wells located in Oklahoma. The plaintiffs have alleged a number of claims, including breach of contract, fraud, breach of fiduciary duty, unjust enrichment, and other claims and seek recovery of compensatory damages, interest, punitive damages and attorney fees on behalf of the allegedproposed class. On November 3, 2014, plaintiffs filed an Amended Petition that did not add any substantive claims, but sought a “hybrid class action” in which they sought certification of certain claims for injunctive relief, reserving the right to seek a further class certification on money damages in the future. Plaintiffs filed an Amended Motion for Class Certification on January 9, 2015, that modified the proposed class to royalty owners in Oklahoma production from July 1, 1993, to the present (instead of 1980 to the present) and sought certification of over 45 separate “ issues” for injunctive or declaratory relief, again, reserving the right to seek a further class certification of money damages in the future. The Company has responded to the petition, deniedits amendment, and the motions for class certification denying the allegations and raisedraising a number of affirmative defenses. Discoverydefenses and legal arguments to each of the claims and filings. Certain discovery was undertaken and the “hybrid” motion was briefed by plaintiffs and the Company. A hearing on the “hybrid” class certification was held on June 1st and 2nd, 2015. On June 11, 2015, the trial court certified a “hybrid” class as requested by plaintiffs. The Company has appealed the trial court’s class certification order, which will be reviewed de novo by the appellate court. The appeal briefing is ongoingcomplete and information and documents continue to be exchanged.ready for determination by the court. An unsuccessful mediation was conducted on December 7, 2015. The Company is not currently able to estimate a reasonably possible loss or range of loss or what impact, if any, the action will have on its financial condition, results of operations or cash flows due to the preliminary status of the matter, the complexity and number of legal and factual issues presented by the matter and uncertainties with respect to, among other things, the nature of the claims and defenses, the potential size of the class, the scope and types of the properties and agreements involved, the production years involved, and the ultimate potential outcome of the matter. The class hasAlthough not been certified. Plaintiffscurrently at issue in the “hybrid” certification, plaintiffs have indicated that if the class is certified they may seek damagesalleged underpayments in excess of $145$200 million that they may claim as damages, which may increase with the passage of time, a majority of which would be comprised of interest. The Company disputes plaintiffs’ claims, disputes that the case meets the requirements for a class action and is vigorously defending the case.

The Company will continue to assert its defenses to the case as certified as well as any future attempt to certify a money damages class.

The Company is involved in various other legal proceedings such asincluding, but not limited to, commercial disputes, claims from royalty and surface owners, property damage claims, personal injury claims, disputes with tax authorities and similarother matters. While the outcome of these legal matters cannot be predicted with certainty, the Company does not expect them to have a material adverse effect on its financial condition, results of operations or cash flows.

Performance Graph

The following performance graph compares the yearly percentage change in the cumulative total shareholder return on our common stock performance with the cumulative total returnsperformance of the Standard & Poor’s 500 Stock Index (“S&P 500 Index”), and the Dow Jones US Oil and Gas Index (“Dow Jones US O&G Index”), and a peer group for the period of companies.

In years prior to 2012,December 2010 through December 2015. The graph assumes the total shareholder returnvalue of the investment in our common stock and in each index was compared to$100 on December 31, 2010 and that any dividends were reinvested. The stock performance shown on the total returnsgraph below is not indicative of the S&P 500 Index and a group of peer companies. Companies included in our peer group represented publicly traded crude oil and natural gas exploration and production companies similar in size and operations to us. In recent years, companies deemed to be peers have been acquired or have merged with other companies in our industry. Additionally, the rapid growth of our Company in recent years has outpaced the growth of our peers. These factors have caused fluctuations in the companies comprising our peer group from one year to the next. To mitigate the impact of these fluctuations and provide more consistency to the performance graph disclosure year after year, in 2012 we elected to replace our peer group with the Dow Jones US O&G Index for disclosure purposes. In this year of transition, we have presented the total returns of both the peer group and Dow Jones US O&G Index in the performance graph below.

The peer group, which represents the group presented in the performance graph from our 2011 Form 10-K, is comprised of Cabot Oil & Gas Corporation, Cimarex Energy Co., Concho Resources Inc., Denbury Resources Inc., Forest Oil Corporation, Newfield Exploration Company, Pioneer Natural Resources Company, Range Resources Corporation, Ultra Petroleum Corp., and Whiting Petroleum Corporation.

The following discussion and analysis should be read in conjunction with our consolidated financial statements and notes, as well as the selected consolidated financial data included elsewhere in this report. Our operating results for the periods discussed below may not be indicative of future performance. For additional discussion of crude oil and natural gas reserve information, please seePart I, Item 1. Business—Crude Oil and Natural Gas Operations. The following discussion and analysis includes forward-looking statements and should be read in conjunction withPart I, Item 1A. Risk Factors in this report, along withCautionary Statement for the Purpose of the “Safe Harbor” Provisions of the Private Securities Litigation Reform Act of 1995at the beginning of this report, for information about the risks and uncertainties that could cause our actual results to be materially different than our forward-looking statements.

Overview

We are an independent crude oil and natural gas company engaged in the exploration, development and production company with properties in the North, South, and East regions of the United States. The North region consists of properties north of Kansas and west of the Mississippi River and includes North Dakota Bakken, Montana Bakken, and the Red River units. The South region includes Kansas and all properties south of Kansas and west of the Mississippi River including the South Central Oklahoma Oil Province (“SCOOP”), Northwest Cana, and Arkoma Woodford plays in Oklahoma. The SCOOP and Northwest Cana plays were previously combined by us and referred to as the Anadarko Woodford play. In December 2012, we sold the producing crude oil and natural gas properties in our East region. Our remaining East region properties are comprised of undeveloped leasehold acreage east of the Mississippi River that will be managed as part of our exploration program.

We focus our exploration activities in large new or developing crude oil and liquids-rich plays that provide us the opportunity to acquire undeveloped acreage positions for future drilling operations. We have been successful in targeting large repeatable resource plays where horizontal drilling, advanced fracture stimulation and enhanced recovery technologies provide the means to economically develop and produce crude oil and natural gas reserves from unconventional formations. In October 2012, we announced a new five-year growth plan to triple our production and proved reserves from year-end 2012 to year-end 2017.

gas. We derive the majority of our operating income and cash flows from the sale of crude oil and natural gas. Wegas and expect growth in our revenues and operating income will primarily depend on commodity prices and our abilitythis to increase our crude oil and natural gas production. In recent months and years, there has been significant volatility in crude oil and natural gas prices due to a variety of factors we cannot control or predict, including political and economic events, weather conditions, and competition from other energy sources. These factors impact supply and demand for crude oil and natural gas, which affect crude oil and natural gas prices. In addition, the prices we realize for our crude oil and natural gas production are affected by price differencescontinue in the markets where we deliver our production.

2012 Highlights

Proved reserves

At December 31, 2012, our estimated proved reserves totaled 784.7 MMBoe, an increase of 54% over proved reserves of 508.4 MMBoe at December 31, 2011. Extensions and discoveries resulting from ourfuture. Our operations are primarily focused on exploration and development activities were the primary drivers of our proved reserves growth in 2012, adding 233.7 MMBoe of proved reserves during the year, with strategic acquisitions adding 82.0 MMBoe. Our extensions and discoveries were primarily driven by successful drilling results and strong production growth in the Bakken field. Our proved reserves in the Bakken field totaled 563.6 MMBoe at December 31, 2012, representing a 92% increase from 294.2 MMBoe at year-end 2011.

Our properties in the Bakken field comprised 72% of our proved reserves at December 31, 2012, with the SCOOP and Northwest Cana plays in Oklahoma comprising 14% and the Red River units in North Dakota, South Dakota and Montana comprising 10%. Estimated proved developed producing reserves were 309.0 MMBoe at

December 31, 2012, representing 39% of our total estimated proved reserves compared with 40% at year-end 2011.

Crude oil reserves comprised 72%, or 561.2 MMBoe, of our estimated proved reserves at December 31, 2012 compared to 64% at December 31, 2011. The increased percentage of crude oil reserves at December 31, 2012 is a reflection of our continued strategy of focusing on the exploration for and development of high-value crude oil and liquids-rich plays.

We seek to operate wells in which we own an interest. At December 31, 2012, we operated wells that accounted for 85% of our total proved reserves and 84% of our PV-10. By controlling operations, we are able to more effectively manage the costs and timing of exploration and development of our properties, including the drilling and fracture stimulation methods used. Additionally, our business strategy has historically focused on reserve and production growth through exploration and development activities. For the three-year period ended December 31, 2012, we added 490.9 MMBoe of proved reserves through extensions and discoveries, compared to 84.4 MMBoe added through acquisitions.

Production, revenues and operating cash flows

For the year ended December 31, 2012, our crude oil and natural gas production totaled 35,716 MBoe (97,583 Boe per day), representing a 58% increase from production of 22,581 MBoe (61,865 Boe per day) for the year ended December 31, 2011. Crude oil represented 70% of our 2012 production compared to 73% for 2011. The decreased percentage of crude oil production resulted from our natural gas production growth in 2012 of 74% outpacing our crude oil production growth of 52% due in part to the connecting of new and existing wells in North Dakota to gas processing plants, thereby resulting in a higher percentage of our production coming from natural gas in 2012.

Our crude oil and natural gas production totaled 9,829 MBoe (106,831 Boe per day) for the fourth quarter of 2012, a 4% increase over production of 9,472 MBoe (102,964 Boe per day) for the third quarter of 2012 and a 42% increase over production of 6,920 MBoe (75,219 Boe per day) for the fourth quarter of 2011. Crude oil represented 72% of our production for the fourth quarter of 2012, 70% for the third quarter of 2012, and 72% for the fourth quarter of 2011.

The increase in 2012 production was primarily driven by higher production from our properties in the North Dakota Bakken field and the Northwest Cana and SCOOP plays in Oklahoma due to the continued success of our drilling programs in those areas. Our Bakken production in North Dakota increased to 18,679 MBoe for the year ended December 31, 2012, a 92% increase over the comparable 2011 period. Fourth quarter 2012 production in North Dakota Bakken totaled 5,430 MBoe, a 6% increase over the third quarter of 2012 and 66% higher than the fourth quarter of 2011. Production in the Northwest Cana play totaled 4,097 MBoe for the year ended December 31, 2012, 134% higher than the same period in 2011. Northwest Cana production increased 22% in the fourth quarter of 2012 compared to the fourth quarter of 2011, yet decreased 15% from the third quarter of 2012 due to reduced drilling activity. Production from our properties in the emerging SCOOP play in south-central Oklahoma totaled 1,654 MBoe for the year ended December 31, 2012, a 297% increase over the comparable 2011 period. SCOOP production totaled 655 MBoe for the 2012 fourth quarter, a 39% increase over the third quarter of 2012 and a 281% increase over the fourth quarter of 2011.

Our crude oil and natural gas revenues for the year ended December 31, 2012 increased 44% to $2.4 billion due to a 58% increase in sales volumes partially offset by a 9% decrease in realized commodity prices compared to the same period in 2011. Our realized price per Boe decreased $6.22 to $66.83 for the year ended December 31, 2012 compared to 2011 due to lower commodity prices and higher crude oil differentials realized. Crude oil represented 89% of our total 2012 crude oil and natural gas revenues compared to 88% for 2011.

Crude oil and natural gas revenues totaled $670.4 million for the fourth quarter of 2012, a 32% increase over revenues of $508.3 million for the 2011 fourth quarter due to a 39% increase in sales volumes partially offset by a 5% decrease in realized commodity prices. Crude oil represented 88% of our total crude oil and natural gas revenues for the fourth quarter of 2012 compared to 89% for the 2011 fourth quarter.

Our cash flows from operating activities for the year ended December 31, 2012 were $1.6 billion, a 53% increase from $1.1 billion provided by our operating activities during the comparable 2011 period. For the fourth quarter of 2012, operating cash flows totaled $484.2 million, 22% higher than operating cash flows of $398.1 million for the 2011 fourth quarter. The increased operating cash flows were primarily due to higher crude oil and natural gas revenues driven mainly by increased sales volumes, partially offset by lower realized sales prices, an increase in realized losses on derivatives and higher production expenses, production taxes, general and administrative expenses and other expenses associated with the growth of our operations over the past year.

Capital expenditures and property acquisitions

For the year ended December 31, 2012, we invested approximately $4.4 billion in our capital program (including $15.0 million of seismic costs and $49.0 million of capital costs associated with increased accruals for capital expenditures), focusing primarily on increased exploration and development in the Bakken field of North Dakota and Montana and the SCOOP, playSTACK, and Northwest Cana areas of Oklahoma.

Business Environment and Outlook
Crude oil prices remained significantly depressed in south-central Oklahoma. Our 20122015 and currently face continued downward pressure due to domestic and global supply and demand factors. The downward price pressure intensified in late 2015 and early 2016, with crude oil prices dropping below $27 per barrel in February 2016, a level not seen since 2003. Natural gas prices faced similar downward pressure in 2015, dropping below $1.70 per MMBtu in December 2015.
In light of the challenges facing our industry, our primary business strategies for 2016 will include: (1) optimizing cash flows through operating efficiencies and cost reductions, (2) high-grading investments based on rates of return and opportunities to convert undeveloped acreage to acreage held by production, and (3) working to balance capital spending with cash flows to minimize new borrowings and maintain ample liquidity.
With the above strategies in mind, and given the uncertainty regarding the timing and magnitude of any price recovery, we have significantly reduced our planned non-acquisition capital spending for 2016 to $920 million, a reduction of 63% compared to $2.50 billion of non-acquisition capital spending in 2015. This non-acquisition investment level is designed to target capital expenditures include $1.3 billionand cash flows being relatively balanced for 2016 at an assumed average West Texas Intermediate benchmark crude oil price of unbudgeted property acquisitions, most notably fromapproximately $37 per barrel for the acquisitions described below.

year, with any cash flow deficiencies being funded by borrowings under our revolving credit facility. Our 2016 drilling program will focus on drilling de-risked acreage in core parts of our key operating areas that provide opportunities for converting undeveloped acreage to acreage held by production, increasing capital efficiency, reducing finding and development costs, and maximizing rates of return.

In December 2012, we acquiredOur 2016 capital budget reflects a planned reduction in operated rig count and deferral of certain producing and undeveloped propertieswell completion activities relative to 2015, primarily in the Bakken. At December 31, 2015, we operated 23 rigs on our properties, which we subsequently reduced to 19 operated rigs in early 2016 by dropping 4 rigs in the Bakken. We expect to maintain an average of 19 operated rigs for full-year 2016 and plan to complete 71 net operated and non-operated wells in 2016, a 74% decrease compared to 271 net well completions in 2015. We plan to defer well completion activities for most of our Bakken playwells in 2016, which is expected to increase our inventory of North Dakota fromdrilled but uncompleted wells during the year. As a third party for $663.3 million.

Revenues
Crude oil and natural gas revenues for 2015 decreased 39% compared to 2014 driven by a 50% decrease in 2012, we increasedrealized crude oil prices and a 57% decrease in realized natural gas prices, the effect of which was partially offset by a 22% increase in crude oil sales volumes and a 44% increase in natural gas sales volumes.
Crude oil and natural gas revenues totaled $551.4 million for the 2015 fourth quarter, a 12% decrease from the 2015 third quarter and 39% lower than the 2014 fourth quarter. Crude oil sales prices for the 2015 fourth quarter averaged $34.23 per barrel, a 12% decrease from the 2015 third quarter and 44% lower than the 2014 fourth quarter. Crude oil sales volumes for the 2015 fourth quarter totaled 13,453 MBbls, a 1% decrease from the 2015 third quarter and 8% higher than the 2014 fourth quarter. Natural gas sales prices for the 2015 fourth quarter averaged $2.07 per Mcf, a 7% decrease from the 2015 third quarter and 52% lower than the 2014 fourth quarter. Natural gas sales volumes for the 2015 fourth quarter totaled 43,807 MMcf, a 2% decrease from the 2015 third quarter and 41% higher than the 2014 fourth quarter.
Proved reserves
At December 31, 2015, our proved reserves totaled 1,226 MMBoe, a decrease of 9% from proved reserves of 1,351 MMBoe at December 31, 2014. Extensions and discoveries from our drilling activities added 253 MMBoe of proved reserves in 2015, which was more than offset by downward reserve revisions totaling 297 MMBoe prompted by lower commodity prices and changes in drilling plans and 81 MMBoe of production during the year. The 12-month average price used to determine year-end proved reserves for crude oil decreased 47% from $94.99 per Bbl for 2014 to $50.28 per Bbl for 2015, while the 12-month average price for natural gas decreased 41% from $4.35 per MMBtu for 2014 to $2.58 per MMBtu for 2015.

Our capital expenditures budget for 2013 is $3.6 billion, excluding acquisitions. Our 2013 capital program is expected to continue focusing on exploratory and development drilling in the Bakken field and 2014.

SCOOP play. We expect to continue participating as a buyer of properties if and when we have the ability to increase our position in strategic plays at favorable terms.

We hedge a portion of our anticipated future production to achieve more predictable cash flows and reduce our exposure to fluctuations in commodity prices. Reducing our exposure to price volatility helps ensure adequate funds are available for our capital program. We expect our cash flows from operations, our remaining cash balance, and our credit facility, including our ability to increase our borrowing capacity thereunder, will be sufficient to meet our budgeted capital expenditure needs for the next 12 months; however, we may choose to access the capital markets for additional financing to take advantage of business opportunities that may arise if such financing can be arranged at favorable terms.

Property dispositions

In 2012, we completed the following dispositions of non-strategic properties in an effort to redeploy capital to our strategic areas that we believe will deliver higher future growth potential. We may continue to seek opportunities to sell non-strategic properties if and when we have the ability to dispose of such assets at favorable terms.

In December 2012, we sold the producing properties in our East region to a third party for $126.4 million and recognized a pre-tax gain on the transaction of $68.0 million. The disposed properties

comprised 399 MBoe, or 1%, of our total crude oil and natural gas production for 2012. Crude oil and natural gas revenues for the disposed properties amounted to $34.6 million for 2012, representing 1% of our total crude oil and natural gas revenues for the year. The disposed properties had represented approximately 1% of our total proved reserves prior to disposition.

In June 2012, we sold certain non-strategic leaseholds and producing properties in Oklahoma to a third party for $15.9 million and recognized a pre-tax gain on the transaction of $15.9 million. The disposed properties represented an immaterial portion of our total proved reserves and production.

In February 2012, we sold certain non-strategic leaseholds and producing properties in Wyomingincreased 12% from 370 MMBoe at year-end 2014 to a third party for $84.4 million and recognized a pre-tax gain on the transaction of $50.1 million. The disposed properties had413 MMBoe at year-end 2015.

Crude oil comprised 57%, or 1%,701 MMBoe, of our 2011 totalproved reserves at December 31, 2015 compared to 64% at year-end 2014. The decreased percentage of crude oil andreserves resulted primarily from the increase in SCOOP reserves as a percentage of our total reserves during the year, which have a higher concentration of liquids-rich natural gas production.

As of December 31, 2015 we had approximately 170 gross (131 net) operated wells that are drilled but not yet completed. Due to current market conditions we have chosen to defer completions on certain wells until commodity prices improve.
Credit facility and liquidity
In February 2015, aggregate lender commitments on our revolving credit facility were increased from $1.75 billion to $2.5 billion and were increased again in November 2015 to $2.75 billion to provide additional liquidity. Further, in November 2015 we entered into a $500 million unsecured term loan maturing in November 2018 and used the proceeds therefrom to repay a portion of our outstanding credit facility borrowings to further enhance our liquidity.
At December 31, 2015, we had $11.5 million of cash and cash equivalents and $1.9 billion of borrowing availability on our credit facility after considering outstanding borrowings and letters of credit. We had $853 million of outstanding borrowings on our credit facility at December 31, 2015.
Credit facility borrowings, net of repayments and exclusive of the use of term loan proceeds, totaled $11.0 million.

$8 million for the 2015 fourth quarter compared to $120 million for the third quarter, $270 million for the second quarter, and $790 million for the first quarter. This decreasing trend resulted from a reduction in capital expenditures due to our efforts to align spending with cash flows in response to decreased commodity prices. Our total debt was nearly flat at December 31, 2015 compared to September 30, 2015.

The 20% increase in crude oil and natural gas properties in our East region to a third party for $126.4 million, subject to customary post-closing adjustments. SeeNotes to Consolidated Financial Statements—Note 13. Property Acquisitions and Dispositions for further discussion of the transaction.

Crude oil production volumes increased 52% during the year ended December 31, 2012in 2015 compared to 2014 was driven by increased production from our properties in North Dakota Bakken and SCOOP. Production in North Dakota Bakken increased 6,623 MBbls, or 21%, over the prior year, ended December 31, 2011. Production increases in the Bakken field, the Northwest Cana play andwhile SCOOP play contributed incremental production volumes in 2012 of 8,493increased 3,545 MBbls, an 81% increase over production in these areas for the same period in 2011.or 97%. Production growth in these areas iswas primarily due to increasedadditional drilling and completion activity resulting from our drilling program. Additionally, production in the Red River units increased 177 MBbls, or 4%, in 2012 due to new wells being completed and enhanced recovery techniques being successfully applied.

Natural gas production volumes increased 27,204 MMcf, or 74%, during the year ended December 31, 2012 compared to the same period in 2011. Natural gas production in the Bakken field increased 9,414 MMcf, or 104%, for the year ended December 31, 2012 compared to the same period in 2011 due to new wells being completed and gas from existing wells being connected to natural gas processing plants in the play. Natural gas production in the Northwest Cana and SCOOP plays in Oklahoma increased 17,839 MMcf, or 156%, due to additional wells being completed and producing in the year ended December 31, 2012 compared to the same period in 2011. Further, natural gas production increased 716 MMcf, or 81%, in non-Bakken areas in the North region compared to 2011 due to the completion of new wells during the period. These increases were partially offset by a decrease in production volumes of 837 MMcf,from our properties in Montana Bakken and the Red River units totaling 1,280 MBbls, or 6%14%, from non-core areas in our South regioncompared to the prior year due to a combination of natural declines in production and reduced drilling activity prompted by the pricing environment foractivity.

The 44% increase in natural gas production in 2015 compared to 2014 was driven by increased production from our properties in the SCOOP, Bakken, and Northwest Cana/STACK areas due to additional wells being completed and producing subsequent to December 31, 2014. Natural gas production in SCOOP increased 36,670 MMcf, or 67% over the prior year, while Bakken production increased 13,842 MMcf, or 37%, and Northwest Cana/STACK production increased 836 MMcf, or 8%. These increases were partially offset by decreases in production from various areas in our North and South regions primarily due to natural declines in production.
The increase in natural gas production as a percentage of our total production from 30% in 2014 to 34% in 2015 primarily resulted from the significant increase in SCOOP production over the past year due in part to a shift in our well completion activities away from the Bakken to higher rate-of-return areas in Oklahoma. Our properties in SCOOP, as well as those in STACK and Northwest Cana, typically produce a higher concentration of liquids-rich natural gas compared to oil-weighted properties in the Bakken. For 2016, we expect to continue shifting our well completion activities to Oklahoma and plan to allocate an increased proportion of our capital spending to the SCOOP, STACK, and Northwest Cana areas.

Revenues

Accordingly, we expect our natural gas production may increase to approximately 40% of our total production for 2016. As crude oil prices recover, we expect to increase our completion activities in the Bakken and shift our production back to a higher proportion of crude oil.

Our totalreduction in capital spending and deferral of well completion activities in 2015, which is expected to intensify in 2016, has adversely impacted our production growth and our 27% year-over-year growth in production realized in 2015 will not be sustained in 2016. We expect our production will average approximately 200,000 Boe per day for the full year of 2016, a 10% decrease from average daily production of 221,715 Boe per day for 2015.
Revenues
Our revenues primarily consist of sales of crude oil and natural gas realized and unrealizedgains and losses resulting from changes in the fair value of our derivative instruments and revenues associated with crudeinstruments.
Crude oil and natural gas service operations.

sales.Crude Oil and Natural Gas Sales. Crude oil and natural gas sales for the year ended December 31, 20122015 were $2.38$2.55 billion, a 44% increase39% decrease from sales of $1.65$4.20 billion for the same period in 2011. Our sales volumes increased 13,053 MBoe, or 58%, over 20112014 primarily due to the success of our drilling programsa significant decrease in the North Dakota Bakken field and Northwest Cana play, along with early success being achieved in the emerging SCOOP play in

Oklahoma. Our realized price per Boe decreased $6.22 to $66.83 for the year ended December 31, 2012 from $73.05 for the year ended December 31, 2011 due to lower commodity prices, and higherpartially offset by an increase in sales volumes.

Our crude oil differentials realized.

sales prices averaged $40.50 per barrel for 2015, a decrease of 50% compared to $81.26 for 2014. Market prices for crude oil remained depressed throughout 2015, resulting in significantly lower realized sales prices compared to the prior year. The differential between NYMEX West Texas Intermediate ("WTI") calendar month average crude oil prices and our realized crude oil priceprices averaged $8.33 per barrel for the year ended December 31, 2012 was $9.062015 compared to $6.39$10.81 for 2014. The improved differential was due in part to increased availability and use of pipeline transportation in the current year to move our crude oil to market with less dependence on more costly rail transportation.

Our realized natural gas sales prices averaged $2.31 per Mcf for 2015, a decrease of 57% compared to $5.40 per Mcf for 2014 due to lower market prices for natural gas and natural gas liquids ("NGLs"). The majority of our natural gas production is sold at our lease locations to midstream purchasers with price realizations impacted by the volume and value of NGLs that the purchasers extract from our sales stream. The difference between our realized natural gas sales prices and NYMEX Henry Hub calendar month natural gas prices was a discount of $0.34 per Mcf for 2015 compared to a premium of $1.02 for 2014. NGL prices in 2015 remained depressed in conjunction with low crude oil prices, which reduced the value of our natural gas sales stream and unfavorably impacted the difference between our realized prices and Henry Hub benchmark pricing. If NGL prices do not recover from current levels, the prices we receive for the year ended December 31, 2011. Overallsale of our natural gas stream in 2016 may continue to be lower than Henry Hub benchmark prices.
Our sales volumes for 2015 increased 17,901 MBoe, or 28%, over 2014 primarily due to an increase in producing wells resulting from the success of our drilling programs in North Dakota Bakken and SCOOP. At various times we have stored crude oil due to pipeline line fill requirements, low commodity prices, or marketing disruptions or we have sold crude oil from inventory. These actions result in differences between produced and sold crude oil volumes. New third party pipeline systems becoming available during 2015 provided for improved transportation of our crude oil to market, which resulted in the sale of

53



crude oil previously stored in inventory and caused crude oil sales volumes to be higher than crude oil production by 147 MBbls for the year.
For the 2015 fourth quarter, crude oil and constrained logistical factors hadnatural gas revenues totaled $551.4 million, representing a negative effect on12% decrease from 2015 third quarter revenues of $628.5 million and a 39% decrease from 2014 fourth quarter revenues of $902.3 million. Revenues for the 2015 fourth quarter were adversely impacted by a decrease in crude oil and natural gas prices late in the year. Our crude oil sales prices averaged $34.23 per barrel in the 2015 fourth quarter compared to $38.95 for the 2015 third quarter and $61.53 for the 2014 fourth quarter. Our natural gas sales prices averaged $2.07 per Mcf in the 2015 fourth quarter compared to $2.23 for the 2015 third quarter and $4.36 for the 2014 fourth quarter.
The decrease in crude oil prices in late 2015 continued into early 2016. As a result, we expect our realized crude oil sales prices during 2012 and resulted in higher differentials compared to 2011. Factors contributing tofor the changing differential included a continued increase in crude oil production across the Williston Basin from the Bakken play as well as increased production and imports from Canada. Additionally, pipeline transportation capacity remained constrained in the Williston Basin throughout 2012 and it was not until the latter part of the year that improved rail transportation takeaway capacity began to have a positive effect on differentials. Positive effects of stronger sales pricing in coastal U.S. markets began to2016 first quarter will be lower than those realized in the 2015 fourth quarterquarter. Crude oil, natural gas and NGL prices have experienced significant volatility in recent months and we are unable to predict the impact future price changes may have on our full year 2016 revenues and differentials.
Crude oil represented 85% of the year despite high costs being incurred for rail transportation. As a result, our total crude oil differentialsand natural gas revenues for both 2015 and 2014. As previously mentioned, for 2016 we expect to NYMEX improved lateallocate an increased proportion of our capital spending to our SCOOP, STACK, and Northwest Cana properties which typically contain higher concentrations of liquids-rich natural gas compared to our properties in the year and averaged $3.21 per barrel forBakken. Accordingly, unless crude oil prices recover significantly, we expect crude oil to comprise a smaller percentage of our 2016 revenues compared to 2015, the fourth quarter.

Derivatives.We have entered into a numberextent of derivative instruments, including fixed price swaps and zero-cost collars, to reduce the uncertainty of future cash flows in order to underpin our capital expenditures and drilling program. We are required to recognize all derivative instruments on the balance sheet as either assets or liabilities measured at fair value. We have not designated our derivative instruments as hedges for accounting purposes. As a result, we mark our derivative instruments to fair value and recognize the realized and unrealized changes in fair value in the consolidated statements of income under the caption “Gain (loss) on derivative instruments, net”, which is a componentuncertain due to the unpredictable nature of total revenues.commodity prices.

Derivatives.

Changes in commodity futures price stripsnatural gas prices during 20122015 had an overall positive neta favorable impact on the fair value of our derivatives, which resulted in net positive revenue adjustments of $154.0$91.1 million for the year. We expect ourOur revenues willmay continue to be significantly impacted, either positively or negatively, by changes in the fair value of our derivative instruments as a result of volatility in crude oil and natural gascommodity prices.

The increase in sales volumes reflected above, partially offset by lower realized sales prices, resulted in a $1.3 million net increase in reclaimed oil revenues to $25.1 million for the year ended December 31, 2012. Additionally, revenues from saltwater disposal and other services increased $5.4 million to $14.0 million resulting from increased activity. Associated crude oil and natural gas service operations expenses increased $5.5 million to $32.2 million for the year ended December 31, 2012 due mainly to an increase in the costs of purchasing and treating reclaimed crude oil for resale and in providing saltwater disposal services.

Operating Costs and Expenses

Production Expenses and Production Taxes and Other Expensesexpenses. Production expenses decreased 1% to $348.9 million in 2015 from $352.5 million in 2014. Production expenses on a per-Boe basis decreased to $4.30 for 2015 compared to $5.58 for 2014. These decreases primarily resulted from curtailed spending and reduced service costs being realized in response to depressed commodity prices, increased 41% to $195.4 million for the year ended December 31, 2012availability and use of water gathering and recycling facilities in 2015, and a higher portion of our production coming from $138.2 million for the year ended December 31, 2011. This increase is primarily the result of higher production volumes from an increasenatural gas wells in the number of producing wells. Production expense per Boe decreased to $5.49 for the year ended December 31, 2012SCOOP area which typically have lower operating costs compared to $6.13 per Boe for the year ended December 31, 2011. This decrease was due in part to higher costs being incurred in the prior year resulting from the abnormal rainfallBakken.
Production taxes and flooding in North Dakota during the 2011 second quarter. The increased 2011 costs, coupled with reduced production from curtailed and shut-in wells in North Dakota during that time, resulted in higher per-unit production expenses in 2011 compared to 2012.other expenses.

Production taxes and other expenses increased $83.6decreased $149.2 million, or 58%43%, to $228.4$200.6 million for the year ended December 31, 2012in 2015 compared to the year ended December 31, 2011 as a result of higher$349.8 million in 2014 primarily due to lower crude oil and natural gas revenues resulting primarily from increased sales volumes. Production taxes and other expenses in the consolidated statements of income include other charges for marketing, gathering, dehydration and compression fees primarily related to natural gas sales in the Oklahoma Woodford and North Dakota Bakken areas of $29.9 million and $13.7 million for the years ended December 31, 2012 and 2011, respectively. The increase in other charges is primarily due to the significant increasedecrease in natural gas sales volumes incommodity prices over the currentprior year. Production taxes excluding other charges,are generally based on the wellhead values of production and vary by state. Production taxes as a percentage of crude oil and natural gas revenues were 7.8% for 2015 compared to 8.2% for 2014, the decrease of which resulted from significant growth over the past year ended December 31, 2012 compared to 7.9% for the year ended December 31, 2011. Thein our SCOOP operations and resulting increase is due to higher taxablein revenues coming from North Dakota, our most active area,Oklahoma, which has lower production tax rates compared to the Bakken. We expect this downward trend in our average production tax rate to continue in 2016 as our operations in Oklahoma continue to

grow in significance and given the passing of upa new law in North Dakota in 2015 that decreased the combined production tax rate in that state from 11.5% to 11.5%10.0% of crude oil revenues. Production taxes are generally based on the wellhead value of production and vary by state. Additionally, some states offer exemptions or reduced production tax rates for wells that produce less than a certain quantity of crude oil or natural gas and to encourage certain activities, such as horizontal drilling and enhanced recovery projects. In Montana and Oklahoma, new horizontal wells qualify for a tax incentive and are taxed at a lower rate during their initial months of production. After the incentive period expires, the tax rate increases to the statutory rate. Our overall production tax rate is expected to further increase as we continue to expand our operations in North Dakota and as production tax incentives we currently receive for horizontal wells reach the end of their incentive periods.

Estimated proved reserves are a key component in our computation of DD&A expense. Holding all other factors constant, if proved reserves are revised downward, the rate at which we record DD&A expense would increase. Downward revisions of proved reserves in 2015 prompted by depressed commodity prices contributed to a slight increase in our DD&A per Boe is partiallyrate for crude oil and natural gas properties this year. If commodity prices remain at current levels for an extended period or decline further, additional downward revisions of proved reserves may occur in the future, which may be significant and would result of a gradual shiftin an increase in our DD&A rate. We are unable to predict the timing and amount of future reserve revisions or the impact such revisions may have on our future DD&A rate.
Property impairments. Total property impairments decreased $214.8 million, or 35%, to $402.1 million for 2015 compared to $616.9 million for 2014.
Impairments of proved properties decreased $185.4 million, or 57%, in 2015 to $138.9 million, of which $27.5 million was recognized in the fourth quarter. The decrease resulted from differences in the severity of commodity price declines and resulting impact on fair value assessments between periods. The sharp pronounced decrease in forward commodity prices in late 2014 triggered significant impairments of previously unimpaired proved properties, with subsequent commodity price changes and impairments in 2015 being less severe.
The 2015 proved property impairments reflect fair value adjustments primarily concentrated in an emerging area with minimal production base from our historic base ofand costly reserve additions ($42.5 million), the Medicine Pole Hills units ($32.5 million, including $9.6 million in the fourth quarter), the Buffalo Red River units ($26.3 million), non-Bakken areas of North Dakota and Montana ($8.2 million), Wyoming properties ($17.9 million, all in the Cedar Hills field to newer production basesfourth quarter), and various legacy areas in the BakkenSouth region ($11.4 million).
Estimated reserves are a key component in assessing proved properties for impairment. If commodity prices remain at current levels for an extended period or decline further, downward revisions of reserves may be significant in the future and Oklahoma Woodford plays. The producingcould result in additional impairments of proved properties in our newer areas typically carry higher DD&A rates due2016. We are unable to predict the higher costtiming and amount of developing reserves in those areas compared to our older, more mature properties.

Given current and projected low prices for natural gas, we have elected to defer drilling on certain dry gas properties, thereby resulting in higherIn 2014, the amortization of undeveloped leasehold costs for an exploratory prospect in Texas was accelerated in response to unsuccessful results and decreased crude oil prices, which resulted in the current year. We currently have no individually significantrecognition of $92.4 million of non-producing properties that are assessed forleasehold impairment on a property-by-property basis.

Impairment provisions for proved properties were $4.3 millioncharges for the year ended December 31, 2012 comparedprospect in 2014, with no leasehold impairments of a similar magnitude in 2015. This decrease was partially offset by higher rates of amortization being applied in 2015 to $16.1 million forundeveloped leasehold costs across various prospects resulting from a reduction in planned drilling activities prompted by the same periodcontinued decrease in 2011. We evaluate proved crude oilcommodity prices in 2015. Our rates of amortization may increase in future periods if commodity prices remain at current levels or decline further and natural gas properties for impairment by comparing their cost basisadditional changes are made to the estimated future cash flows on a field basis. If the cost basis is in excess of estimated future cash flows, then we impair it based on an estimate of fair value based on discounted cash flows. Impairments of proved properties in 2012 primarily reflect uneconomic operating results in a non-Woodford single-well field in our South region. Impairment provisions for proved properties in 2011 reflect uneconomic operating results for initial wells drilled on our acreage in the Niobrara play in Colorado.

General and Administrative Expenses. Generaladministrative expenses. Total general and administrative (“G&A”) expenses increased $48.9$5.1 million, or 3%, to $121.7$189.8 million for the year ended December 31, 2012in 2015 from $72.8$184.7 million for the comparable period in 2011.2014. G&A expenses include non-cash charges for equity compensation of $29.1$51.8 million and $16.6$54.4 million for the years ended December 31, 20122015 and 2011,2014, respectively. The increase in equity compensation in 2012 resulted from larger grants of restricted stock due to employee growth and new executive management personnel along with an increase in our grant-date stock prices, which resulted in increased expense recognition in 2012 compared to the prior year. G&A expenses excluding equity compensation increased $36.4 million for the year ended December 31, 2012 compared to the same period in 2011. The increase was due in part to an increase in personnel costs and office-related expenses associated with our rapid growth. Over the past year, our Company has grown from having 609 total employees in December 2011 to 753 total employees in December 2012, a 24% increase. Additionally, in March 2011 we announced plans to relocate our corporate headquarters from Enid, Oklahoma to Oklahoma City, Oklahoma. Our relocation was completed during 2012. For the year ended December 31, 2012, we recognized approximately $7.8 million of costs in G&A expenses associated with the relocation compared to $3.2 million in 2011. Cumulative relocation costs recognized through December 31, 2012 totaled approximately $11.0 million.

The decrease in G&A expenses on a per-Boe basis in 2015 was driven by a 28% increase in sales volumes from new well completions with no comparable increase in G&A expenses. Per-Boe G&A expenses may continue to trend downward in 2016 as a result of our ongoing efforts to reduce spending in response to depressed commodity prices.
The decrease in non-cash equity compensation expense on a per-Boe basis was due to an increase in the estimated rate of forfeitures of unvested restricted stock based on historical experience, which resulted in lower recognition of expense in 2015, coupled with the increase in sales volumes from new well completions with no comparable increase in equity compensation expense.
Interest Expense.expense. Interest expense increased $64.0$29.2 million, or 10%, to $140.7$313.1 million in 2015 from $283.9 million in 2014 due to an increase in our weighted average outstanding long-term debt obligations. Our weighted average outstanding long-term debt balance for 2015 was $6.9 billion with a weighted average interest rate of 4.4% compared to averages of $5.6 billion and 4.9% for 2014. The increase in outstanding debt resulted from borrowings incurred subsequent to December 31, 2014 to fund our 2015 capital program.
Income Taxes. We recorded an income tax benefit for the year ended December 31, 20122015 of $181.4 million compared to income tax expense of $584.7 million for 2014, resulting in effective tax rates of approximately 34% and 37%, respectively, after taking into account permanent taxable differences and valuation allowances. For 2015, we provided for income taxes at a combined federal and state tax rate of 38% of pre-tax losses generated by our operations in the United States. Our 2015 effective tax rate was impacted by a $13.5 million valuation allowance recognized against deferred tax assets associated with operating loss carryforwards generated by our Canadian subsidiary during the year for which we do not believe we will realize a benefit.

Crude oil production increased 9,541 MBbls, or 27%, in 2014 compared to 2013. Production in the Bakken field increased 8,371 MBbls, or 31%, over the prior year, while SCOOP production increased 1,648 MBbls, or 82%. Production growth in these areas was primarily due to increased drilling and completion activity resulting from $76.7our drilling program. These increases were partially offset by a decrease of 132 MBbls associated with non-strategic properties in Colorado and Wyoming that were sold in March 2014. Additionally, production from our properties in the Red River units decreased 336 MBbls, or 7%, over the prior year due to a combination of natural declines in production and reduced drilling activity.
Natural gas production increased 26,565 MMcf, or 30%, in 2014 compared to 2013. Production in the Bakken field increased 7,728 MMcf, or 26%, in 2014 due to new wells being completed and gas from existing wells being connected to natural gas processing plants in the play. Natural gas production in SCOOP increased 25,579 MMcf, or 87%, due to additional wells being completed and producing in 2014 compared to 2013. These increases were partially offset by decreases in production from various areas in our North and South regions, primarily in Arkoma Woodford and Northwest Cana, due to natural declines in production.
Revenues
Crude oil and natural gas sales. Crude oil and natural gas sales for 2014 were $4.20 billion, an 18% increase from sales of $3.57 billion for 2013. Our sales volumes increased 13,565 MBoe, or 27%, over 2013 primarily due to the success of our drilling programs in the Bakken and SCOOP plays. Realized commodity prices decreased 8% in 2014 resulting from the significant decrease in crude oil prices in the 2014 fourth quarter along with a widening of sales price differentials.
Crude oil represented 85% of our total 2014 crude oil and natural gas revenues compared to 88% for 2013. The decreased percentage of crude oil revenues resulted from a significant increase in SCOOP revenues as a percentage of our total revenues in 2014. Our properties in SCOOP produce a higher concentration of liquids-rich natural gas compared to certain other operating areas such as the Bakken.
An increase in crude oil line fill requirements associated with new pipelines put into service during 2014 along with initial tank fill at new storage facilities contributed to an increase in crude oil stored in inventory in 2014. This caused crude oil sales volumes to be lower than crude oil production by 408 MBbls for 2014, with 143 MBbls of the difference occurring during the fourth quarter.
Crude oil and natural gas revenues totaled $902.3 million for the comparable periodfourth quarter of 2014, representing a 22% decrease from 2014 third quarter revenues of $1.16 billion and nearly flat compared to 2013 fourth quarter revenues of $903.2 million. Revenues for the 2014 fourth quarter were adversely impacted by increased crude oil inventory levels and decreased crude oil prices. Our crude oil sales prices averaged $61.53 per barrel in 2011the 2014 fourth quarter compared to $85.49 for the 2014 third quarter and $84.47 for the 2013 fourth quarter.
The differential between NYMEX West Texas Intermediate ("WTI") calendar month crude oil prices and our realized crude oil prices averaged $10.81 per barrel for 2014 compared to $8.23 for 2013. Our crude oil price differential to WTI averaged $11.35 per barrel in the 2014 fourth quarter compared to $11.77 for the 2014 third quarter and $13.05 for the 2013 fourth quarter.
Our realized natural gas sales prices averaged $5.40 per Mcf for 2014, an increase of 11% over $4.87 per Mcf for 2013. This increase primarily reflected improved prices realized in connection with higher market prices for natural gas during 2014. Our average natural gas sales price for the 2014 fourth quarter decreased to $4.36 per Mcf compared to $5.10 for the 2014 third quarter and $5.11 for the 2013 fourth quarter. This decrease was driven by lower sales prices for natural gas liquids in late 2014, which reduced the total value of our natural gas sales stream. NGL prices decreased significantly in late 2014 in conjunction with the decrease in crude oil prices.
The premium of our realized natural gas sales prices over NYMEX Henry Hub calendar month natural gas prices averaged $1.02 per Mcf for 2014 compared to $1.21 per Mcf for 2013. The smaller premium in 2014 was partly driven by the aforementioned decrease in NGL market prices in late 2014, which unfavorably impacted the premium of our realized prices over Henry Hub benchmark pricing. Because of significantly lower NGL prices in late 2014, our natural gas sales price

57



premium decreased to $0.35 per Mcf for the 2014 fourth quarter compared to $1.04 for the 2014 third quarter and $1.51 for the 2013 fourth quarter.
Derivatives. Changes in commodity prices during 2014 had an overall favorable impact on the fair value of our derivatives, which resulted in positive revenue adjustments of $560 million for 2014, including $433 million of gains recognized on crude oil derivative liquidations in the 2014 fourth quarter.

Operating Costs and Expenses
Production expenses. Production expenses increased 25% to $352.5 million in 2014 from $282.2 million in 2013. This increase was primarily the result of an increase in the number of producing wells and resulting 28% increase in production volumes. Production expense per Boe decreased to $5.58 for 2014 compared to $5.69 for 2013.
Production taxes and other expenses. Production taxes and other expenses increased $51.0 million, or 17%, to $349.8 million in 2014 compared to $298.8 million in 2013 primarily as a result of higher crude oil and natural gas revenues driven by increased sales volumes. Production taxes as a percentage of crude oil and natural gas revenues were 8.2% for 2014 compared to 8.3% for 2013.

The increase in DD&A per Boe in 2014 resulted from an increased use of enhanced completion methods that increased completed well costs. Additionally, certain exploratory wells, primarily in non-core areas, resulted in more expensive reserve additions. These factors contributed to an increase in DD&A on a per-Boe basis in 2014 compared to 2013.
Property impairments. Total property impairments increased $396.4 million, or 180%, to $616.9 million for 2014 compared to $220.5 million for 2013 due primarily to write-downs resulting from the significant decrease in crude oil prices in the 2014 fourth quarter which adversely impacted the recoverability of capitalized costs in certain operating areas.
Impairment provisions for proved properties increased $272.5 million, or 526%, in 2014 to $324.3 million, of which $255.0 million was recognized in the fourth quarter. The 2014 impairments were primarily concentrated in the Buffalo Red River units ($96.9 million), the Medicine Pole Hills units ($75.9 million), various non-core areas in our South region ($39.7 million), non-Bakken areas of North Dakota and Montana ($18.4 million), and certain emerging areas with limited production history and costly reserve additions ($75.2 million). Impairments for 2014 also include an $18.2 million lower of cost or market adjustment for crude oil inventories.
Impairments of non-producing properties increased $123.9 million, or 73%, in 2014 to $292.6 million, of which $138.8 million was recognized in the fourth quarter. The increase was due to higher rates of amortization being applied to undeveloped leasehold costs resulting from changes in management’s estimates of undeveloped properties not expected to be developed before lease expiration, particularly in the fourth quarter in response to the significant decrease in crude oil prices which altered our drilling plans. Undeveloped leasehold costs for a prospect in Texas in the early stages of exploration and development were written down in 2014 due to changes in drilling plans in response to unsuccessful results and lower crude oil prices, which resulted in the recognition of $92.4 million of non-producing leasehold impairment charges for the prospect, of which $84.6 million was recognized in the fourth quarter.
General and administrative expenses. G&A expenses increased $40.3 million, or 28%, to $184.7 million in 2014 from $144.4 million in 2013. G&A expenses include non-cash charges for equity compensation of $54.4 million and $39.9 million for 2014 and 2013, respectively. The increase in equity compensation resulted from a higher value of restricted stock grants being made in 2014 due to employee growth, which resulted in increased expense recognition compared to the prior year.
G&A expenses other than equity compensation increased $25.8 million, or 25%, in 2014 compared to 2013. The increase was primarily due to an increase in personnel costs and office-related expenses associated with our employee growth. In 2014, our Company grew from having 929 total employees in December 2013 to 1,188 total employees in December 2014, a 28% increase.

Interest expense. Interest expense increased $48.6 million, or 21%, to $283.9 million in 2014 from $235.3 million in 2013 due to an increase in our weighted average outstanding long-term debt obligations. Our weighted average outstanding long-term debt balance for the year ended December 31, 20122014 was approximately $2.3$5.6 billion with a weighted average interest rate of 5.6%4.9% compared to a weighted average outstanding long-term debt balanceaverages of approximately $970.0 million$4.3 billion and a weighted average interest rate of 7.2%5.2% for the comparable period in 2011.2013. The increase in outstanding debt resulted from higher borrowings being incurred to fund our increased amounts of capital expenditures and property acquisitions in 2012 compared to 2011. On March 8, 2012 and August 16, 2012, we issued $800 million and $1.2 billion, respectively, of 5% Senior Notes due 2022 and used the net proceeds from those issuances to repay credit facility borrowings, to fund a portion of our 2012 capital budget and for general corporate purposes.budget.

Our weighted average outstanding credit facility balance increased to $322.1 million for the year ended December 31, 2012 compared to $70.0 million for the year ended December 31, 2011. The weighted average interest rate on our credit facility borrowings was 2.3% for the year ended December 31, 2012 compared to 2.4% for the same period in 2011. At December 31, 2012, we had $595 million of outstanding borrowings on our credit facility compared to $358.0 million outstanding at December 31, 2011. The increase in credit facility borrowings in 2012 was driven by the aforementioned increase in capital expenditures and property acquisitions during the year.

Income Taxes. We recorded income tax expense of $584.7 million for the year ended December 31, 2012 of $415.8 million2014 compared to $258.4$448.8 million for the year ended December 31, 2011.2013. We provideprovided for income taxes at a combined federal and state tax rate of approximately 38%37% for both 2014 and 2013 after taking into account permanent taxable differences. SeeNotes to Consolidated Financial Statements—Note 8. Income Taxes for more information.

Crude oil production volumes increased 39% during the year ended December 31, 2011 compared to the year ended December 31, 2010. Production increases in the Bakken field and the SCOOP and Northwest Cana plays in the Oklahoma Woodford formation contributed incremental production volumes in 2011 of 4,410 MBbls, a 72% increase over production in these areas for the same period in 2010. Production growth in these areas was primarily due to increased drilling activity and higher well completions resulting from our accelerated drilling program for 2011. Additionally, production in the Cedar Hills field increased 203 MBbls, or 5%, in 2011 due to new wells being completed and enhanced recovery techniques being successfully applied.

Natural gas production volumes increased 12,728 MMcf, or 53%, during the year ended December 31, 2011 compared to the same period in 2010. Natural gas production in the North Dakota Bakken field was up 3,529 MMcf, or 88%, for the year ended December 31, 2011 compared to the same period in 2010 due to new wells being completed and gas from existing wells being connected to natural gas processing plants in North Dakota. Natural gas production in the SCOOP and Northwest Cana plays increased 8,971 MMcf, or 366%, due to additional wells being completed and producing in the year ended December 31, 2011 compared to the same period in 2010. Further, natural gas production increased 502 MMcf in non-Woodford areas of our South region due to the completion of new wells during the period. These increases were partially offset by a 498 MMcf decrease in natural gas production from our Arkoma Woodford properties, which consist primarily of dry gas. In 2011, we scaled back our Arkoma Woodford drilling program due to the pricing environment for natural gas.

Revenues

Our total revenues are comprised of sales of crude oil and natural gas, realized and unrealized changes in the fair value of our derivative instruments and revenues associated with crude oil and natural gas service operations.

Crude Oil and Natural Gas Sales. Crude oil and natural gas sales for the year ended December 31, 2011 were $1,647.4 million, a 74% increase from sales of $948.5 million for the same period in 2010. Our sales volumes increased 6,662 MBoe, or 42%, over the same period in 2010 due to the success of our drilling programs in the North Dakota Bakken field and the SCOOP and Northwest Cana plays. Our realized price per Boe increased $13.35 to $73.05 for the year ended December 31, 2011 from $59.70 for the year ended December 31, 2010. The differential between NYMEX calendar month average crude oil prices and our realized crude oil price per barrel for the year ended December 31, 2011 was $6.39 compared to $9.02 for the year ended December 31, 2010. In

2011, a significant portion of our operated crude oil production in the North region was sold in markets other than Cushing, Oklahoma and was priced, apart from transportation costs, at a premium to West Texas Intermediate benchmark pricing, which resulted in improved differentials.

Derivatives.Changes in commodity futures price strips during 2011 had an overall negative net impact on the fair value of our derivatives, which resulted in net negative revenue adjustments of $30.0 million for the year. We expect our revenues will continue to be significantly impacted, either positively or negatively, by changes in the fair value of our derivative instruments as a result of volatility in crude oil and natural gas prices. The following table presents the impact on total revenues related to realized and unrealized gains and losses on derivative instruments for the periods presented.

Crude Oil and Natural Gas Service Operations. Our crude oil and natural gas service operations consist primarily of the treatment and sale of lower quality crude oil, or reclaimed crude oil. The table below shows the volumes and prices for the sale of reclaimed crude oil for the periods presented.

   Year Ended December 31,   Variance 

Reclaimed crude oil sales

Average sales price ($/Bbl)

  $92.30    $69.35    $22.95  

Sales volumes (MBbls)

   259     227     32  

The average sales price for reclaimed crude oil sold from our central treating units was $22.95 per barrel higher for the year ended December 31, 2011 than the comparable 2010 period. This contributed to an increase in reclaimed crude oil revenues of $7.0 million to $23.8 million and contributed to an overall increase in crude oil and natural gas service operations revenue of $11.1 million for the year ended December 31, 2011. Also contributing to the increase in crude oil and natural gas service operations revenue was a $3.3 million increase in saltwater disposal income resulting from increased activity. Associated crude oil and natural gas service operations expenses increased $8.6 million to $26.7 million during the year ended December 31, 2011 from $18.1 million during the year ended December 31, 2010 due mainly to an increase in the costs of purchasing and treating reclaimed crude oil for resale and in providing saltwater disposal services.

Operating Costs and Expenses

Production Expenses and Production Taxes and Other Expenses. Production expenses increased 48% to $138.2 million for the year ended December 31, 2011 from $93.2 million for the year ended December 31, 2010. This increase was primarily the result of higher production volumes from an increase in the number of producing wells. Production expenses per Boe increased to $6.13 for the year ended December 31, 2011 from $5.87 per Boe for the year ended December 31, 2010. Contributing to the per-unit increase were increases in well site and road maintenance costs and saltwater disposal costs in the 2011 second quarter, all resulting from abnormal rainfall

and flooding in North Dakota in April and May 2011. Also contributing to the per-unit increase were higher workover expenditures from increased activity as well as general inflationary pressure on the costs of oilfield services and equipment.

Production taxes and other expenses increased $68.2 million, or 89%, to $144.8 million during the year ended December 31, 2011 compared to the year ended December 31, 2010 as a result of higher crude oil and natural gas revenues resulting from increased commodity prices and sales volumes along with the expiration of various tax incentives. Production taxes and other expenses include charges for marketing, gathering, dehydration and compression fees primarily related to natural gas sales in the Oklahoma Woodford and North Dakota Bakken areas of $13.7 million and $6.1 million for the year ended December 31, 2011 and 2010, respectively. The increase in other charges is primarily due to the significant increase in natural gas sales volumes in 2011. Production taxes, excluding other charges, as a percentage of crude oil and natural gas revenues were 7.9% for the year ended December 31, 2011 compared to 7.5% for the year ended December 31, 2010. The increase was due to the expiration of various tax incentives coupled with higher taxable revenues in North Dakota, our most active area, which has production tax rates of up to 11.5% of crude oil revenues. Our overall production tax rate is expected to further increase as we continue to expand our operations in North Dakota and as production tax incentives we currently receive for horizontal wells reach the end of their incentive periods.

Exploratory geological and geophysical costs increased $10.2 million for the year ended December 31, 2011 due to an increase in acquisitions of seismic data in connection with our increased capital budget for 2011. Dry hole costs increased $4.9 million in 2011 resulting from increased drilling activity. Dry hole costs in 2011 were mainly concentrated in Arkoma Woodford and Michigan.

Depreciation, Depletion, Amortization and Accretion. Total DD&A increased $147.3 million, or 60%, in the year ended December 31, 2011 compared to the year ended December 31, 2010 primarily due to a 43% increase in production volumes. The following table shows the components of our DD&A on a unit of sales basis.

Depreciation, depletion, amortization and accretion

  $17.33    $15.33  

The increase in DD&A per Boe was partially the result of a gradual shift in our production from our historic base of the Red River units in the Cedar Hills field to newer production bases in the Bakken and Oklahoma Woodford plays. The producing properties in our newer areas typically carry higher DD&A rates due to the higher cost of developing reserves in those areas compared to our older, more mature properties.

Property Impairments. Property impairments increased in the year ended December 31, 2011 by $43.5 million to $108.5 million compared to $65.0 million for the year ended December 31, 2010.

Impairments of non-producing properties increased $29.1 million for the year ended December 31, 2011 to $92.4 million compared to $63.3 million for the year ended December 31, 2010. The increase resulted from a larger base of amortizable costs in 2011 coupled with changes in management’s estimates of the undeveloped properties no longer expected to be developed before lease expiration. Given the pricing environment for natural gas, we elected to defer drilling on certain dry gas properties, thereby resulting in higher amortization of costs in 2011. In 2011, we had no individually significant non-producing properties that were assessed for impairment on a property-by-property basis.

Impairment provisions for proved crude oil and natural gas properties were $16.1 million for the year ended December 31, 2011 compared to $1.7 million for the same period in 2010. Impairments of proved properties in 2011 primarily reflect uneconomic operating results for initial wells drilled on our acreage in the Niobrara play in Colorado. Impairments in 2010 reflect uneconomic operating results in the East region and a non-Bakken Montana field in the North region.

General and Administrative Expenses. General and administrative (“G&A”) expenses increased $23.7 million to $72.8 million for the year ended December 31, 2011 from $49.1 million for the comparable period in 2010. G&A expenses include non-cash charges for equity compensation of $16.6 million and $11.7 million for the years ended December 31, 2011 and 2010, respectively. The increase in equity compensation in 2011 resulted from larger grants of restricted stock due to employee growth along with an increase in our grant-date stock prices during the year which increased expense recognition. G&A expenses excluding equity compensation increased $18.8 million for the year ended December 31, 2011 compared to the same period in 2010. The increase was primarily related to an increase in personnel costs and office-related expenses associated with our rapid growth. In 2011, we grew from 493 total employees in December 2010 to 609 total employees in December 2011, a 24% increase. In March 2011, we announced plans to relocate our corporate headquarters from Enid, Oklahoma to Oklahoma City, Oklahoma. For the year ended December 31, 2011, we recognized approximately $3.2 million of costs in G&A expenses associated with the relocation.

Interest Expense. Interest expense increased $23.6 million, or 44%, for the year ended December 31, 2011 compared to the same period in 2010 due to increases in our weighted average outstanding long-term debt balance and our weighted average interest rate. Our weighted average interest rate for the year ended December 31, 2011 was 7.2% with a weighted average outstanding long-term debt balance of $970.0 million compared to a weighted average interest rate of 7.0% with a weighted average outstanding long-term debt balance of $685.8 million for the same period in 2010. We issued $200 million of 7 3/8% Senior Notes in April 2010 and $400 million of 7 1/8% Senior Notes in September 2010, the net proceeds of which were used to repay credit facility borrowings that carried lower interest rates.

Our weighted average outstanding credit facility balance decreased to $70.0 million for the year ended December 31, 2011 compared to $121.7 million for the year ended December 31, 2010. The weighted average interest rate on our credit facility borrowings was 2.4% for the year ended December 31, 2011 compared to 2.7% for the same period in 2010. At December 31, 2011, we had $358.0 million of outstanding borrowings on our credit facility at a weighted average interest rate of 2.0%.

Income Taxes. We recorded income tax expense for the year ended December 31, 2011 of $258.4 million compared to $90.2 million for the year ended December 31, 2010. We provide for income taxes at a combined federal and state tax rate of approximately 38% after taking into account permanent taxable differences. See Notes to Consolidated Financial Statements—Note 8. Income Taxes for more information.


Liquidity and Capital Resources

Our primary sources of liquidity have historically been cash flows generated from operating activities, financing provided by our revolving credit facility and the issuance of debt and equity securities. Our 58% increase in sales volumes for the year ended December 31, 2012 compared to the same period in 2011 resulted in improved cash flows from operations. Our liquidity has improved as we have more borrowing availability on our credit facility resulting from increases made in 2012 to our credit facility’s borrowing base and aggregate commitments as discussed below under the headingRevolving Credit Facility.

At December 31, 2012,2015, we had $35.7$11.5 million of cash and cash equivalents and $900.2 millionapproximately $1.9 billion of borrowing availability on our revolving credit facility after considering outstanding borrowings and letters of credit.

We are focused on balancing our 2016 capital spending with cash flows in order to


59



minimize new borrowings and maintain ample liquidity. At February 19, 2016, outstanding borrowings totaled $830 million with approximately $1.9 billion of borrowing availability on our credit facility.
Based on our 2016 capital expenditure budget, our forecasted cash flows and projected levels of indebtedness, we expect to maintain compliance with the covenants under our credit facility, three-year term loan, and senior note indentures for at least the next 12 months. Further, we expect to meet in the ordinary course of business other contractual cash commitments to third parties pursuant to the various agreements subsequently described under the heading Contractual Obligations and in Part II, Item 8. Notes to Consolidated Financial Statements—Note 10. Commitments and Contingencies, recognizing we may be required to meet such commitments even if our business plan assumptions were to change.
Cash Flows

Cash flows from operating activities

Our net cash provided by operating activities was $1.6$1.86 billion and $1.1$3.36 billion for the years ended December 31, 20122015 and 2011,2014, respectively. The increasedecrease in operating cash flows was primarily due to higherlower crude oil and natural gas revenues driven by higher sales volumes,lower realized commodity prices, a decrease in cash gains on derivative settlements, and an increase in interest expense over the past year, all partially offset by lower realized sales prices, an increaseproduction taxes.
If the depressed commodity price environment existing in realized losses on derivatives and increases in production expenses, production taxes, general and administrative expenses, and other expenses associated withFebruary 2016 persists or worsens, we expect our 2016 operating cash flows will be lower than 2015 levels, the growthextent of our operations duringwhich is uncertain due to the year.

unpredictable nature of commodity prices.

Cash flows used in investing activities

During the years ended December 31, 20122015 and 2011,2014, we had cash flows used in investing activities (excluding proceeds from asset sales)sales and other) of $4.1$3.08 billion and $2.0$4.72 billion, respectively, related to our capital program, inclusive of dry hole costs. The increasecosts and property acquisitions. Cash acquisition capital expenditures totaled $61.0 million and $203.9 million for the years ended December 31, 2015 and 2014, respectively. Cash capital expenditures excluding acquisitions totaled $3.02 billion and $4.51 billion for the years ended December 31, 2015 and 2014, respectively, the decrease of which was driven by a decrease in cash flows used in investing activities in 2012 was primarily due to our larger capital budget and related drilling activity for 2015. Our cash capital expenditures for 2015 include the payment of amounts owed at December 31, 2014 in connection with our 2014 drilling program and associated $519.9 million decrease in accruals for 2012 coupled with an increase in property acquisitions incapital expenditures for the current year. year ended December 31, 2015.
The use of cash for capital expenditures during the year ended December 31, 2015 was partially offset by proceeds received from dispositions of non-strategic assets during the year.asset dispositions. Proceeds from the sale of assets amounted to $214.7$34.0 million for 2012,2015, primarily related to our February 2012the disposition of certain Wyoming propertiesnon-producing leasehold acreage in Oklahoma for $84.4 million,proceeds totaling $25.9 million.
For 2016, we currently expect our June 2012 disposition of certain Oklahoma properties for $15.9 million, and our December 2012 disposition of certain East region properties for $126.4 million, of which $14.0 million had not yet been received at December 31, 2012. Proceeds from the sale of assets amounted to $30.9 million for 2011, primarily relatedcash flows used in investing activities will be significantly lower than 2015 levels due to our March 2011 disposition of certain Michigan propertiesdecision to reduce our planned drilling activity for $22.0 million2016 in response to the continued decrease in crude oil prices in late 2015 and our December 2011 disposition of certain North region propertiesearly 2016. Our capital expenditures for $8.02016 are budgeted to be $920 million.

Cash flows from financing activities

Net cash provided by financing activities for the year ended December 31, 2012 was $2.32015 totaled $1.19 billion, primarily resulting from net borrowings of $688 million on our revolving credit facility and $500 million of proceeds received from a new three-year term loan entered into in November 2015. Our 2015 operating cash flows were adversely impacted by decreased commodity prices, leading to an increase in credit facility borrowings incurred for the payment of amounts owed in connection with our 2014 drilling program and to fund a portion of our 2015 drilling program.

Net cash provided by financing activities for the year ended December 31, 2014 totaled $1.23 billion, primarily resulting from the receipt of $787.0 million of net proceeds from the March 2012 issuance of $800 million of 5% Senior Notes due 2022 and an additional $1.21$1.68 billion of net proceeds received from the issuance of $1.2 billion of additional 2022 Notes at 102.375% of par in August 2012, along with $237 million of net borrowings made on

our credit facility during the year to fund a portion of our 2012 capital program. Net cash provided by financing activities of $982.4 million for the year ended December 31, 2011 was primarily the result of receiving $659.7 million of net proceeds from the issuance of an aggregate 10,080,000 shares$1.0 billion of our common stock3.8% Senior Notes due 2024 and $700 million of 4.9% Senior Notes due 2044 in March 2011 coupled withMay 2014, partially offset by net borrowingsrepayments of $328$110 million on our revolving credit facility to fund a portionand the July 2014 redemption of our 20118.25% Senior Notes due 2019 for $317.5 million.


The level of credit facility borrowings we incurred in 2015 is not expected to continue in 2016. We are seeking to generally balance our 2016 capital program.

expenditures with cash flows, which we expect will result in significantly reduced capital spending and credit facility borrowings in 2016 compared to 2015.

Future Sources of Financing

Although we cannot provide any assurance, assuming continued strength in crude oil prices and successful implementation of our business strategy, we believe funds from operating cash flows, our remaining cash balance and availability under our revolving credit facility including our ability to increase our borrowing capacity thereunder, should be sufficient to meet our cash requirements inclusive of, but not limited

Our 2016 capital expenditures budget is reflective of the depressed commodity price environment and has been established based on an expectation of available cash flows, with any cash flow deficiencies expected to be funded by borrowings under our revolving credit facility.
If cash flows are materially impacted by a further decline in commodity prices, we have the ability to reduce our capital expenditures or utilize the availability of our revolving credit facility if needed to fund our operations. On November 4, 2015 we refinanced $500 million of then outstanding credit facility borrowings into a new three-year term loan, and we may choose to access the capital markets for additional financing or capital to take advantage of business opportunities that may arise if such financing can be arranged aton favorable terms.

Based on Additionally, we may choose to sell assets to obtain funding for our planned production growthoperations and derivative contracts we have in place to limit the downside risk of adverse price movements associated with the forecasted sale of future production, wecapital program.

We currently anticipate we will be able to generate or obtain funds sufficient to meet our short-term and long-term cash requirements. We intend to finance future capital expenditures primarily through cash flows from operations and through borrowings under our revolving credit facility, but we may also issue debt or equity securities or sell assets. The issuance of additional debt requires a portion of our cash flows from operations be used for the payment of interest and principal on our debt, thereby reducing our ability to use cash flows to fund working capital, capital expenditures and acquisitions. The issuance of additional equity securities could have a dilutive effect on the value of our common stock.

Revolving Credit Facility

credit facility

We have aan unsecured credit facility, which hadmaturing on May 16, 2019, with aggregate lender commitments totaling $1.5 billion and a borrowing base of $3.25 billion at December 31, 2012, subject to semi-annual redetermination. The most recent borrowing base redetermination was completed in December 2012, whereby the lenders approved an increase in the borrowing base from $2.75 billion, to $3.25 billion. In July 2012, our lender commitments were increased from the previous level of $1.25 billion to the current level of $1.5 billion. The aggregate commitment levelwhich may be further increased from time to time (provided no default exists) up to a total of $4.0 billion upon agreement between the lesser of $2.5 billion or the borrowing base then in effect. Borrowings under the credit facility bear interest at a rate per annum equal to the London Interbank Offered Rate (LIBOR) for one, two, three or six months, as elected by us, plus a margin ranging from 150 to 250 basis points, depending on the percentage of the borrowing base utilized, or the lead bank’s reference rate (prime) plus a margin ranging from 50 to 150 basis points.

Company and participating lenders. The commitments under our credit facility, which matures on July 1, 2015, are from a syndicate of 1417 banks and financial institutions. We believe each member of the current syndicate has the capability to fund its commitment. If one or more lenders cannot fund its commitment, we would not have the full availability of the $1.5 billion commitment.

We had $595.0 million of outstanding borrowings and $900.2 million of borrowing availability (after considering outstanding borrowings and letters of credit) on our credit facility at December 31, 2012. The outstanding borrowings at December 31, 2012 mainly represent borrowings incurred to fund a portion of our December 2012 acquisition of North Dakota Bakken properties for $663.3 million. At November 30, 2012, prior to the acquisition, we had no borrowings outstanding on our credit facility.

As of February 15, 2013,19, 2016, we had $840.0 million of outstanding borrowings and $655.2 millionapproximately $1.9 billion of borrowing availability on our credit facility after considering outstanding borrowings and letters of credit. Borrowings bear interest at market-based interest rates plus a margin that is based on the terms of the borrowing and the credit ratings assigned to our senior, unsecured, long-term indebtedness.

The commitments under our revolving credit facility are not dependent on a borrowing base calculation subject to periodic redetermination based on changes in commodity prices and proved reserves. Additionally, downgrades or other negative rating actions with respect to our credit rating, such as the recent downgrades by S&P and Moody's that occurred in February 2016, do not trigger a reduction in our current credit facility commitments, nor do such actions trigger a security requirement or change in covenants. The recent downgrades of our credit rating will, however, trigger a 0.250% increase in outstanding borrowings subsequent to December 31, 2012 resulted from borrowings incurred to fundour credit facility's interest rate and a portion0.075% increase in the rate of commitment fees paid on unused borrowing availability under our 2013 capital program.

credit facility.

Our revolving credit facility contains restrictive covenants that may limit our ability to, among other things, incur additional indebtedness, sell assets, make loans to others, make investments, enter into mergers, change material contracts, incur liens, and engage in certain othersale and leaseback transactions, without the prior consentand merge, consolidate or sell all or substantially all of the lenders.our assets. Our credit agreementfacility also contains requirementsa requirement that we maintain a current ratio of not less than 1.0 to 1.0 and a ratio of total fundedconsolidated net debt to EBITDAXtotal capitalization ratio of no greater than 4.00.65 to 1.0. As defined by our credit agreement, the current ratio represents our ratio of current assets to current liabilities, inclusive of available borrowing capacity under the credit agreement and exclusive of current balances associated with derivative contracts and asset retirement obligations. EBITDAX represents earnings before interest expense, income taxes, depreciation, depletion, amortization and accretion, property impairments, exploration expenses, non-cash gains and losses resulting from the requirements of accounting for derivatives, and non-cash equity compensation expense. EBITDAX is not a measure of net income or operating cash flows as determined by U.S. GAAP. Reconciliations of net income and operating cash flows to EBITDAX are provided subsequently under the captionNon-GAAP Financial Measures. The total funded debt to EBITDAX1.00. This ratio represents the ratio of net debt (total debt less cash and cash equivalents) divided by the sum of outstanding borrowings and lettersnet debt plus total shareholders' equity plus, to the extent resulting in a reduction of credit under our revolving credit facility plus our note payable and senior note obligations, divided by total EBITDAX forshareholders' equity, the most recent four quarters. amount of any non-cash impairment charges incurred, net of any tax effect, after June 30, 2014.
We were in compliance with theseour revolving credit facility covenants at December 31, 20122015 and expect to maintain compliance for at least the next 12 months. At December 31, 2012,2015, our currentconsolidated net debt to total capitalization ratio, as defined in the credit facility as amended, was 1.60.58 to 1.0 and1.00. As we are focused on balancing our total funded debt2016 capital spending with cash flows to EBITDAX ratio was 1.8 to 1.0. Weminimize new borrowings, we do not believe the restrictivecredit facility covenants are reasonably likely to limit our ability to undertake additional debt or equity financing to a material extent.

In the future, we may not be able to access adequate funding under our credit facility as a result of (i) a decrease in our borrowing base due to the outcome of a subsequent borrowing base redetermination, or (ii) an unwillingness or inability on the part of our lending counterparties to meet their funding obligations or increase their commitments to the borrowing base amount. We expect the next borrowing base redetermination to occur in the second quarter of 2013. Declines in commodity prices could result in a determination to lower the borrowing base in the future and, in such case, we could be required to repay any indebtedness in excess of the borrowing base.

If we are unable to access funding on acceptable terms when needed, we may not be able to fully implement our business plans, complete new property acquisitions to replace our reserves, take advantage of business opportunities, respond to competitive pressures, or refinance our debt obligations as they come due, any of which could have a material adverse effect on our operations and financial results.

Derivative Activities

As part of our risk management program, we hedge a portion of our anticipated future crude oil and natural gas production to achieve more predictable cash flows and to reduce our exposure to fluctuations in crude oil and natural gas prices. Reducing our exposure to price volatility helps ensure adequate funds are available for our capital program. Our decision on the quantity and price at which we choose to hedge our future production is based in part on our view of current and future market conditions and our desire to have the cash flowsextent if needed to fundsupport our business. At December 31, 2015, our total debt would have needed to independently increase by approximately $2.6 billion, or 36%, above existing levels at that date (with no corresponding increase in cash or reduction in refinanced debt) to reach the developmentmaximum covenant ratio of 0.65 to 1.00.

Senior Note Maturities

On March 8, 2012, we issued $800 millionSK E&S Co. Ltd ("SK") of 5% Senior Notes due 2022 and received net proceeds of approximately $787.0 million after deducting the initial purchasers’ fees. The net proceeds were usedSouth Korea to repayjointly develop a significant portion of the borrowings then outstanding under our credit facility.

On August 16, 2012, we issued an additional $1.2 billion of 5% Senior Notes due 2022 (the “New Notes”). The New Notes were issued pursuantCompany's Northwest Cana natural gas properties. Pursuant to the indenture applicableagreement SK will fund, or carry, 50% of our drilling and completion costs attributable to the $800an area of mutual interest within our Northwest Cana properties until approximately $270 million has been expended by SK on our behalf. As of December 31, 2015, approximately$200 million of 5% the carry had yet to be realized and is expected to be realized over the next four years.

Future Capital Requirements
Senior Notes previously issued on March 8, 2012, resulting in a total of $2.0 billion aggregate principal amount of 5% Senior Notes due 2022 being issued under that indenture. The New Notes have substantially identical terms to the $800 million of Senior Notes originally issued in March 2012. The New Notes were sold at 102.375% of par value, resulting in net proceeds of approximately $1.21 billion after deducting the initial purchasers’ fees. We used a portion of the net proceeds from the offering to repay all amounts then outstanding under our credit facility and used the remaining net proceeds to fund a portion of our 2012 capital budget and for general corporate purposes.

Term loan
In November 2015, we entered into a $500 million unsecured term loan that matures in full in November 2018 and bears interest at variable market-based interest rates plus a margin that is based on the terms of the borrowing and the credit ratings assigned to the Company's senior, unsecured, long-term indebtedness. Downgrades or other negative rating actions with respect to our credit rating, such as the recent downgrades that occurred in February 2016, do not trigger a security requirement or change in covenants for the term loan. The recent downgrades of our credit rating will, however, trigger a 0.125% increase in our term loan's interest rate.
The covenant requirements in the three-year term loan are consistent with the covenants in our revolving credit facility, including the requirement that we maintain a consolidated net debt to total capitalization ratio of no greater than 0.65 to 1.0. We were in compliance with the three-year term loan's covenants at December 31, 2015 and expect to maintain compliance for at least the next 12 months.
Capital Expenditures

We evaluate opportunities to purchase or sell crude oil and natural gas properties and expect to participate as a buyer or seller of properties at various times. We seek acquisitions that utilize our technical expertise or offer opportunities to expand our existing core areas. Acquisition expenditures are not budgeted.

Our 2013planned non-acquisition capital spending for 2016 has been set based on an expectation of available cash flows and is designed to target capital expenditures and cash flows being relatively balanced for 2016, with any cash flow deficiencies being funded by borrowings under our revolving credit facility.

We expect to participate as a buyer of properties when and if we have the ability to increase our position in our strategic plays at favorable terms.

Although we cannot provide any assurance, assuming continued strength in crude oil prices and successful implementationspend 35% of our business strategy, including2016 capital expenditures in North Dakota Bakken and 28% in SCOOP. Other key investment areas will be the futureSTACK play, with 15% of capital expenditures, and our joint development area in Northwest Cana, with 7% of capital expenditures. The remaining 15% of our proved reserves2016 budget will target other capital expenditures such as routine leasing and realization of our cash flows as anticipated, we believe funds from operating cash flows, our remaining cash balance,renewals, work-overs, and our credit facility, including our ability to increase our borrowing capacity thereunder, will be sufficient to fund our planned 2013 capital budget; however, we may choose to accessfacilities.


Our rig activity and the capital markets for additional financing to take advantage of business opportunities that may arise if such financing can be arranged at favorable terms. The actual amount and timing of our capital expenditures may differ materially from our estimatesbudget as a result of, among other things, access to capital, available cash flows, unbudgeted acquisitions, actual drilling results, the availability of drilling rigs and other services and equipment, the availability of transportation capacity, changes in commodity prices, and regulatory, technological and competitive developments.

We monitor our capital spending closely based on actual and projected cash flows and may continue to scale back our spending should commodity prices decrease further. Conversely, an increase in commodity prices could result in increased capital expenditures. We expect to continue participating as a buyer of properties when and if we have the ability to increase our position in strategic plays at competitive terms.

Commitments and Contingencies for additional discussion.

In addition to the operational pipeline transportation commitments described above, we are a party to 5-year firm transportation commitments for future pipeline projects being considered for development that are not yet operational. Such projects require the granting of regulatory approvals or otherwise require significant additional construction efforts by our counterparties before being completed. Future commitments under the non-operational arrangements total approximately $1.0 billion at December 31, 2012, representing aggregate transportation charges expected to be incurred over the 5-year terms of the arrangements assuming the proposed pipeline projects are completed and become operational. The timing of the commencement of pipeline operations is not known due to uncertainties involving matters such as regulatory approvals, resolution of legal and environmental disputes, construction progress and the ultimate probability of pipeline completion. Accordingly, the timing of our obligations under these non-operational arrangements cannot be predicted with certainty and may not be incurred on a ratable basis over a calendar year or may not be incurred at all. Although timing is uncertain, our obligations under these arrangements are not expected to begin until at least 2014.

We are not committed under existing contracts to deliver fixed and determinable quantities of crude oil or natural gas in the future.

Crude Oil and Natural Gas Hedging

As part of our risk management program, we hedge a portion of our anticipated future crude oil and natural gas production to achieve more predictable cash flows and to reduce our exposure to fluctuations in crude oil and natural gas prices. Reducing our exposure to price volatility helps ensure adequate funds are available for our capital program. Our decision on the quantity and price at which we choose to hedge our future production is based in part on our view of current and future market conditions and our desire to have the cash flows needed to fund the development of our inventory of undeveloped crude oil and natural gas reserves in conjunction with our growth strategy. While the use of hedging arrangements limits the downside risk of adverse price movements, their use also limits future revenues from upward price movements. The use of hedging transactions also involves the risk that the counterparties will be unable to meet the financial terms of such transactions. Our derivative contracts are with multiple counterparties to minimize our exposure to any individual counterparty. Substantially all of our derivative contracts are with parties that are lenders (or affiliates of lenders) under our credit facility. For a discussion of the potential risks associated with our hedging program, refer toPart I, Item 1A. Risk Factors—Our derivative activities could result in financial losses or reduce our earnings.

Our derivative contracts are settled based upon reported settlement prices on commodity exchanges, with crude oil derivative settlements based on NYMEX West Texas Intermediate pricing or Inter-Continental Exchange pricing for Brent crude oil and natural gas derivative settlements based on NYMEX Henry Hub pricing. Please seeNotes to Consolidated Financial Statements—Note 5. Derivative Instrumentsfor further discussion of the accounting applicable to our derivative instruments, a summary of open contracts as of December 31, 2012 and the estimated fair value of those contracts as of that date.

Between January 1, 2013 and February 15, 2013, we entered into additional derivative contracts summarized in the tables below. None of these contracts have been designated for hedge accounting.

Common Stock Issued in Exchange for Acquired Assets

On March 27, 2012, we entered into a Reorganization and Purchase and Sale Agreement (the “Agreement”) with Wheatland Oil Inc. (“Wheatland”) and the shareholders of Wheatland. Wheatland is owned 75% by the Revocable Inter Vivos Trust of Harold G. Hamm, a trust of which Harold G. Hamm, our Chief Executive Officer, Chairman of the Board and principal shareholder is the trustee and sole beneficiary, and 25% by our Vice Chairman of Strategic Growth Initiatives, Jeffrey B. Hume. The Agreement provided for the acquisition by us, through the issuance of shares of our common stock, of all of Wheatland’s right, title and interest in and to certain crude oil and natural gas properties and related assets, in which we also owned an interest, in the states of Mississippi, Montana, North Dakota and Oklahoma and the assumption of certain liabilities related thereto.

A special meeting of our shareholders was held on August 10, 2012 for the purpose of voting on whether to approve the issuance of shares of our common stock pursuant to the Agreement as required by Oklahoma state law, the requirements of the New York Stock Exchange Listed Company Manual and the terms of the Agreement. The proposal to issue shares of our common stock pursuant to the Agreement received the requisite affirmative shareholder votes at the August 10, 2012 special meeting to satisfy the necessary approval requirements. As a result, the Wheatland transaction was consummated and closed on August 13, 2012, with an effective date of January 1, 2012. At closing, after considering customary purchase price adjustments, we issued an aggregate of approximately 3.9 million shares of our common stock, par value $0.01 per share, to the shareholders of Wheatland in accordance with the terms of the Agreement. The fair value of the consideration transferred at closing was approximately $279 million. All purchase price adjustments arising after the closing date as allowed for under the Agreement, which amounted to $0.5 million being owed to the Company by Wheatland, have been agreed upon by the parties and are reflected in our consolidated financial statements at December 31, 2012.

Critical Accounting Policies and Estimates

Our consolidated financial statements and related footnotes contain information that is pertinent to our management’s discussion and analysis of financial condition and results of operations. PreparationThe preparation of financial statements in conformity with generally accepted accounting principles generally accepted in the United States requires our management to select appropriate accounting policies and to make estimates judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure and estimation of contingent assets and liabilities. However, theSee Part II, Item 8. Notes to Consolidated Financial Statements—Note 1. Organization and Summary of Significant Accounting Policies for descriptions of our major accounting principles used by us generally do not change ourpolicies. Certain of these accounting policies involve judgments and uncertainties to such an extent that there is a reasonable likelihood that materially different amounts could have been reported cash flowsunder different conditions or liquidity. Interpretation of existing rules must be done and judgments must be made on how the specifics of a given rule apply to us.

if different assumptions had been used.

In management’s opinion, the most significant reporting areas impacted by management’s judgments and estimates are crude oil and natural gas reserve estimations, revenue recognition, the choice of accounting method for crude oil and natural gas activities and derivatives, impairment of assets, income taxes and income taxes.contingent liabilities. These areas are discussed below. Management’s judgments and estimates in these areas are based on information available from both internal and external sources, including engineers, geologists and historical experience in similar matters.matters and are believed to be reasonable under the circumstances. We evaluate our estimates and assumptions on a regular basis. Actual results could differ from the estimates as additional information becomes known.

Crude Oil and Natural Gas Reserves Estimation and Standardized Measure of Future Cash Flows

Our external independent reserve engineers, Ryder Scott, and internal technical staff prepare the estimates of our crude oil and natural gas reserves and associated future net cash flows. The SEC has defined proved reserves as the estimated quantities of crude oil and natural gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs and under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates renewal is reasonably certain. Even though Ryder Scott and our external independent reserve engineers and internal technical staff are knowledgeable and follow authoritative guidelines for estimating reserves, they must make a number of subjective assumptions based on professional judgments in developing the reserve estimates. Estimates of reserves and their values, future production rates, and future costs and expenses are inherently uncertain for various reasons, including many factors beyond the Company's control. Reserve estimates are updated by us at least annuallysemi-annually and take into account recent production levels and other technical information about each of our fields.
Crude oil and natural gas reserve engineering is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be precisely measured. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Periodic revisions to the estimated reserves and future cash flows may be necessary as a result of a number of factors, including reservoir performance, new drilling, crude oil and natural gas prices, changes in costs, technological advances, new geological or geophysical data, or other economic factors. Accordingly, reserve estimates are often differentmay differ significantly from the quantities of crude oil and natural gas ultimately recovered. For the years ended December 31, 2015, 2014, and 2013, our proved reserves were revised downward from prior years' reports by approximately 297.2 MMBoe, 107.9 MMBoe, and 96.1 MMBoe, respectively. We cannot predict the amounts or timing of future reserve revisions. If such
Estimates of proved reserves are key components of the Company's most significant financial estimates including the computation of depreciation, depletion, amortization and impairment of proved crude oil and natural gas properties. Holding all other factors constant, if proved reserves are revised downward, the rate at which we record DD&A expense would increase, reducing net income. Future revisions are significant, theyof reserves may be material and could significantly alter future depreciation, depletion, and amortization expense and may result in material impairments of assets.

At December 31, 2015, our proved reserves totaled 1,226 MMBoe as determined using 12-month average prices of $50.28 per barrel for crude oil and $2.58 per MMBtu for natural gas. Crude oil prices existing in February 2016 are significantly lower than the 2015 average price used to determine our year-end proved reserves. Holding all other factors constant, if crude oil prices used in our year-end reserve estimates were decreased by $15.00 per barrel, thereby approximating the pricing environment existing in February 2016, our proved reserves at December 31, 2015 could decrease by approximately 146 MMBoe, or 12%. If the proved reserves used in our DD&A calculations had been lower by 12% across all fields throughout 2015, our DD&A expense for 2015 would have increased by an estimated $235 million, or 13%. Our DD&A calculations for oil and gas properties are performed on a field basis and revisions to proved reserves will not necessarily be applied ratably across all fields and may not be applied to some fields at all. Further, reserve revisions in significant fields may individually affect our DD&A rate. As a result, the impact on DD&A expense from a 12% revision in reserves cannot be predicted with certainty and may result in a change that is greater or less than 13%.
Revenue Recognition

We derive substantially all of our revenues from the sale of crude oil and natural gas. Crude oil and natural gas revenues are recordedrecognized in the month the product is delivered to the purchaser and title transfers. We generally receive payment from one to three months after the sale has occurred. EachAt the end of each month, to record revenue we estimate the volumesamount of production

Variances between estimated revenues and actual amounts received for all prior months are recorded in the month payment is received and are reflected in our consolidatedfinancial statements of income as crude oil and natural gas sales. These variances have historically not been material.

Successful Efforts Method of Accounting

Our business is subject to accounting rules that are unique to the crude oil and natural gas industry. Two generally accepted methods of accounting for oil and gas activities are available - the successful efforts method and the full cost method. The most significant differences between these two methods are the treatment of exploration costs and the manner in which the carrying value of oil and gas properties are amortized and evaluated for impairment. We use the successful efforts method of accounting for our crude oil and natural gas properties, whereby costs incurredproperties. See Part II, Item 8. Notes to acquire mineral interests in crude oilConsolidated Financial Statements—Note 1. Organization and natural gas properties,Summary of Significant Accounting Policies for further discussion of the accounting policies applicable to drill and equip exploratory wells that find proved reserves, to drill and equip development wells, and expenditures for enhanced recovery operations are capitalized. Geological and geophysical costs, seismic costs incurred for exploratory projects, lease rentals and costs associated with unsuccessful exploratory wells or projects are expensed as incurred. Coststhe successful efforts method of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. To the extent a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between capitalized development costs and exploration expense. Maintenance, repairs and costs of injection are expensed as incurred, except that the costs of replacements or renewals that expand capacity or improve production are capitalized.

Depreciation, depletion, and amortization of capitalized drilling and development costs of crude oil and natural gas properties, including related support equipment and facilities, are generally computed using the unit-of-production method on a field basis based on total estimated proved developed crude oil and natural gas reserves. Amortization of producing leaseholds is based on the unit-of-production method using total estimated proved reserves. In arriving at rates under the unit-of-production method, the quantities of recoverable crude oil and natural gas reserves are established based on estimates made by our internal geologists and engineers and external independent reserve engineers. Service properties, equipment and other assets are depreciated using the straight-line method over estimated useful lives of 3 to 40 years. Upon sale or retirement of depreciable or depletable property, the cost and related accumulated depreciation, depletion and amortization are eliminated from the accounts and the resulting gain or loss, if any, is recognized. Unit of production rates are revised whenever there is an indication of a need, but at least in conjunction with semi-annual reserve reports. Revisions are accounted for prospectively as changes in accounting estimates.

accounting.

Derivative Activities

We may utilize derivative contracts to hedge against the variability in cash flows associated with the forecasted sale of our future crude oil and natural gas production. In addition, we may utilize basis contracts to hedge the differential between NYMEX posted prices and those of our physical pricing points. We do not use derivative instruments for trading purposes. Under accounting rules, we may elect to designate those derivatives that qualify for hedge accounting as cash flow hedges against the price we will receive for our future crude oil and natural gas production. We have elected not to designate any of our price risk management activities as cash flow hedges. As a result, we mark our derivative instruments to fair value and recognize the realized and unrealized changes in fair value in current earnings. As such, we are likely to experience significant non-cash volatility in our reported earnings during periods of commodity price volatility. Derivative assets and liabilities with the same counterparty and subject to contractual terms which provide for net settlement are reported on a net basis on our consolidated balance sheets.

In determining the amounts to be recorded for our open derivative contracts, we are required to estimate the fair value of the derivatives. We use an independent third party to provide our derivative valuations. The third party’s valuation models for derivative contracts are industry-standard models that consider various inputs including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. The calculation of the fair value ofcalculations for our collar contracts requirescollars and written call options require the use of an option-pricing model. The estimated future prices are compared to the prices fixed by the derivative agreements and the resulting estimated future cash inflows or outflows over the lives of the derivatives are discounted to calculate the fair value of the derivative contracts. These pricing and discounting variables are sensitive to market volatility as well as changes in future price forecasts and interest rates. See Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk for a discussion of the sensitivity of derivative fair value calculations to changes in forward commodity prices.
We validate our derivative valuations through management review and by comparison to our counterparties’ valuations for reasonableness.

Differences between our fair value calculations and counterparty valuations have historically not been material.

Impairment of Assets

All of our long-lived assets are monitored for potential impairment when circumstances indicate the carrying value of an asset may be greater than its future net cash flows, including cash flows from risk adjustedrisk-adjusted proved reserves.

Estimated future net cash flows associated with risk-adjusted probable and possible reserves may be taken into consideration when determining fair value when such reserves exist and are economically recoverable.

Proved crude oil and natural gas properties are reviewed for impairment on a field-by-field basis. If the carrying amount of a field exceeds its estimated undiscounted future cash flows, the carrying amount of the field is reduced to its estimated fair value using a discounted cash flow model. For producing properties, the impairment evaluations involve a significant amount of judgment since the results are based on estimated future events, such as future sales prices for crude oil and natural gas, future costs to produce those products, estimates of future crude oil and natural gas reserves to be recovered and the timing thereof, the economic and regulatory climates and other factors. The need to test a field for impairment may result from significant declines in sales prices or downward revisions to crude oil and natural gas reserves. Any assets held for sale are reviewed for impairment when we approve the plan to sell. Estimates of anticipated sales prices and recoverable reserves are highly judgmental and are subject to material revision in future periods.
Impairment provisions for producing properties totaled $138.9 million for 2015, of which $27.5 million was recognized in the fourth quarter. Commodity price assumptions used for the year-end December 31, 2015 impairment calculations were based on publicly available average annual forward commodity strip prices through year-end 2020 and were then escalated at 3% per year thereafter. Holding all other factors constant, as forward commodity prices decrease, our probability for recognizing producing property impairments may increase, or the magnitude of impairments to be recognized may increase. Conversely, as forward commodity prices increase, our probability for recognizing producing property impairments may decrease, or the magnitude of impairments to be recognized may decrease or be eliminated. As of December 31, 2015, the forward commodity strip prices for the year 2020 used in our fourth quarter impairment calculations averaged $53.80 per barrel for crude oil and $3.18 per Mcf for natural gas. Forward crude oil strip prices existing in February 2016 are lower than the year-end 2015 crude oil strip prices. If forward crude oil prices remain at current levels for an extended period or decline further, additional

Non-producing crude oil and natural gasif any.

Impairment losses for non-producing properties, which primarily consist primarily of undeveloped leasehold costs and costs associated with the purchase of certain proved undeveloped reserves, are assessed for impairment on a property-by-property basis for individually significant balances, if any, and on an aggregate basis by prospect for individually insignificant balances. If the assessment indicates an impairment, a loss is recognized by providing a valuation allowance atamortizing the level consistent withportion of the level atproperties’ costs which impairment was assessed.management estimates will not be transferred to proved properties over the lives of the leases based on drilling plans, experience of successful drilling, and the average holding period. The impairment assessment isassessments are affected by economic factors such as the results of exploration activities, commodity price outlooks, anticipated drilling programs, remaining lease terms, and potential shifts in business strategy employed by management. For individually insignificant non-producing properties, impairment losses are recognized by amortizing the portion of the properties’ costs which management estimates will not be transferred to proved properties over the lives of the leases based on experience of successful drilling and the average holding period. The estimated timing and rate of successful drilling is highly judgmental and is subject to material revision in future periods as better information becomes available.

Income Taxes

We make certain estimates and judgments in determining our income tax expense for financial reporting purposes. These estimates and judgments occur in the calculation of certain deferred tax assets and liabilities that arise from differences in the timing and recognition of revenue and expense for tax and financial reporting purposes. Our federal and state income tax returns are generally not prepared or filed before the consolidated financial statements are prepared; therefore, we estimate the tax basis of our assets and liabilities at the end of each period as well as the effects of tax rate changes, tax credits and net operating loss carryforwards. Adjustments related to these estimates are recorded in our tax provision in the period in which we file our income tax returns. Further, we must assess the likelihood that we will be able to recover or utilize our deferred tax assets. If recovery is not likely, we must record a valuation allowance against such deferred tax assets for the amount we would not expect to recover, which would result in an increase to our income tax expense. As of December 31, 2012,2015, we believe all deferred tax assets, recorded onnet of valuation allowances, reflected in our consolidated balance sheets will ultimately be utilized. We consider future taxable income in making such assessments. Numerous judgments and assumptions are inherent in the determination of future taxable income, including factors such as future operating conditions (particularly related to prevailing crude oil and natural gas prices). If our estimates and judgments change regarding our ability to utilize our deferred tax assets, our tax provision could increase in the period it is determined that it is more likely than not that a deferred tax asset will not be utilized.

Our effective tax rate is subject to variability from period to period as a result of factors other than changes in federal and state tax rates and/or changes in tax laws which can affect tax-paying companies. Our effective tax rate is affected by changes in the allocation of property, payroll, and revenues between states in which we own property as rates vary from state to state. Due to the size of our gross deferred tax balances, a small change in our estimated future tax rate can have a material effect on current period earnings.

Contingent Liabilities
A provision for legal, environmental and other contingencies is charged to expense when a loss is probable and the loss or range of loss can be reasonably estimated. Determining when liabilities and expenses should be recorded for these contingencies and the appropriate amounts of accruals is subject to an estimation process that requires subjective judgment of management. In certain cases, management’s judgment is based on the advice and opinions of legal counsel and other advisers, the interpretation of laws and regulations which can be interpreted differently by regulators and/or courts of law, the experience of the Company and other companies dealing with similar matters, and management’s decision on how it intends to respond to a particular matter; for example, a decision to contest it vigorously or a decision to seek a negotiated settlement. Actual losses can differ from estimates for various reasons, including differing interpretations of laws and opinions and assessments on the amount of damages. We closely monitor known and potential legal, environmental and other contingencies and make our best estimate of when or if to record liabilities and losses for matters based on available information.
Off-Balance Sheet Arrangements

Currently, we do not have any off-balance sheet arrangements with unconsolidated entities to enhance liquidity and capital resources. However, as is customary in the crude oil and natural gas industry, we have various contractual commitments that are not reflected in the consolidated balance sheets as shown underPart II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations.

Recent Accounting Pronouncement Not Yet Adopted

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-11,Balance Sheet (Topic 210)–Disclosures about Offsetting Assets and Liabilities. The new standard requires an entity to disclose information about offsetting arrangements to enable financial statement users to understand the effect of netting arrangements on an entity’s financial position. The disclosures are

required for recognized financial instruments and derivative instruments that are subject to offsetting under current accounting literature or are subject to master netting arrangements irrespective of whether they are offset. The objective of the new disclosures is to facilitate comparison between entities that prepare financial statements on the basis of U.S. GAAP and entities that prepare financial statements under International Financial Reporting Standards. The disclosure requirements are effective for periods beginning on or after January 1, 2013 and must be applied retrospectively to all periods presented on the balance sheet. We will adopt the requirements of ASU No. 2011-11 with the preparation of our Form 10-Q for the quarter ending March 31, 2013, which will require additional footnote disclosures for our derivative instruments and are not expected to have a material effect on our financial position, results of operations or cash flows.

We are monitoring the joint standard-setting efforts of the FASB and International Accounting Standards Board. There are a number of pending accounting standards being targeted for completion in 2013 and beyond, including, but not limited to, standards relating to revenue recognition, accounting for leases, fair value measurements, and accounting for financial instruments. Because these pending standards have not yet been finalized, at this time we are not able to determine the potential future impact these standards will have, if any, on our financial position, results of operations or cash flows.

Pending Legislative and Regulatory Initiatives

The crude oil and natural gas industry in the United States is subject to various types of regulation at the federal, state and local levels. Laws, rules, regulations, policies,See Part I, Item 1. Business—Regulation of the Crude Oil and interpretations affecting the crude oil and natural gas industry have been pervasive and are continuously reviewed by legislators and regulators, including the imposition of new or increased requirements on us and other industry participants. Following isNatural Gas Industry for a discussion of significant laws and regulations that have been enacted or are currently being considered by regulatory bodies that may affect us in the areas in which we operate.

Hydraulic fracturing. Some activists have attempted to link hydraulic fracturing to various environmental problems, including adverse effects to drinking water supplies and migration of methane and other hydrocarbons. As a result, several federal agencies are studying the environmental risks with respect to hydraulic fracturing or evaluating whether to restrict its use. From time to time, legislation has been introduced in the U.S. Congress to amend the federal Safe Drinking Water Act to eliminate an existing exemption for hydraulic fracturing activities from the definition of “underground injection,” thereby requiring the crude oil and natural gas industry to obtain permits for hydraulic fracturing and to require disclosure of the additives used in the process. If adopted, such legislation could establish an additional level of regulation and permitting at the federal level. Scrutiny of hydraulic fracturing activities continues in other ways. The White House Council on Environmental Quality is coordinating an administration-wide review of hydraulic fracturing practices, and a number of federal agencies are analyzing environmental issues associated with hydraulic fracturing. The EPA has commenced a multi-year study of the potential environmental impacts of hydraulic fracturing, the draft results of which are anticipated to be available in 2014. Further, on May 11, 2012, the Bureau of Land Management (“BLM”) issued a proposed rule that would require public disclosure of chemicals used in hydraulic fracturing operations, and impose other operational requirements for all hydraulic fracturing operations on federal lands, including Native American trust lands. The Department of the Interior announced on January 18, 2013 that the BLM will issue a revised draft rule by March 31, 2013. In addition to these federal initiatives, several state and local governments, including states in which we operate, have moved to require disclosure of fracturing fluid components or otherwise to regulate their use more closely. In certain areas of the United States, new drilling permits for hydraulic fracturing have been put on hold pending development of additional standards. We voluntarily participate in FracFocus, a national publicly accessible Internet-based registry developed by the Ground Water Protection Council and the Interstate Oil and Gas Compact Commission. This registry, located atwww.fracfocus.org, provides our industry with an avenue to voluntarily disclose additives used in the hydraulic fracturing process. We currently disclose the additives used in the hydraulic fracturing process on all wells we operate.

The adoption of any future federal, state or local laws or implementing regulations imposing permitting or reporting obligations on, or otherwise limiting, the hydraulic fracturing process could make it more difficult and

more expensive to complete crude oil and natural gas wells in low-permeability formations, increase our costs of compliance and doing business, and delay, prevent or prohibit the development of natural resources from unconventional formations. Compliance, or the consequences of any failure to comply by us, could have a material adverse effect on our financial condition and results of operations. At this time it is not possible to estimate the potential impact on our business if any such federal or state legislation is enacted into law.

Climate change. Federal, state and local laws and regulations are increasingly being enacted to address concerns about the effects the emission of carbon dioxide and other identified “greenhouse gases” may have on the environment and climate worldwide. These effects are widely referred to as “climate change.” Since its December 2009 endangerment finding regarding the emission of carbon dioxide, methane and other greenhouse gases, the EPA has begun regulating sources of greenhouse gas emissions under the federal Clean Air Act. Among several regulations requiring reporting or permitting for greenhouse gas sources, the EPA finalized its “tailoring rule” in May 2010 that identifies which stationary sources of greenhouse gases are required to obtain permits to construct, modify or operate on account of, and to implement the best available control technology for, their greenhouse gases. In November 2010, the EPA also finalized its greenhouse gas reporting requirements for certain oil and gas production facilities that emit 25,000 metric tons or more of carbon dioxide equivalent per year. The rule requires annual reporting to the EPA of greenhouse gas emissions by such regulated facilities.

Moreover, in recent years the U.S. Congress has considered establishing a cap-and-trade program to reduce U.S. emissions of greenhouse gases, including carbon dioxide and methane. Under past proposals, the EPA would issue or sell a capped and steadily declining number of tradable emissions allowances to certain major sources of greenhouse gas emissions so that such sources could continue to emit greenhouse gases into the atmosphere. These allowances would be expected to escalate significantly in cost over time. The net effect of such legislation, if adopted, would be to impose increasing costs on the combustion of carbon-based fuels such as crude oil, refined petroleum products, and natural gas. In addition, while the prospect for such cap-and-trade legislation by the U.S. Congress remains uncertain, several states, including states in which we operate, have adopted, or are in the process of adopting, similar cap-and-trade programs.

As a crude oil and natural gas company, the debate on climate change is relevant to our operations because the equipment we use to explore for, develop and produce crude oil and natural gas emits greenhouse gases. Additionally, the combustion of carbon-based fuels, such as the crude oil and natural gas we sell, emits carbon dioxide and other greenhouse gases. Thus, any current or future federal, state or local climate change initiatives could adversely affect demand for the crude oil and natural gas we produce by stimulating demand for alternative forms of energy that do not rely on the combustion of fossil fuels, and therefore could have a material adverse effect on our business. Although our compliance with any greenhouse gas regulations may result in increased compliance and operating costs, we do not expect the compliance costs for currently applicable regulations to be material. Moreover, while it is not possible at this time to estimate the compliance costs or operational impacts for any new legislative or regulatory developments in this area, we do not anticipate being impacted to any greater degree than other similarly situated competitors.

For a discussion of our environmental protection initiatives, particularly with respect to our efforts to reduce flaring of natural gas, seePart I, Item 1. Regulation of the Crude Oil and Natural Gas Industry—Environmental, Health and Safety Regulation.

Dodd-Frank Wall Street Reform and Consumer Protection Act. In July 2010, the Dodd-Frank Act was enacted into law. This financial reform legislation includes provisions that require derivative transactions that are currently executed over-the-counter to be executed through an exchange and be centrally cleared. The Dodd-Frank Act requires the CFTC, the SEC, and other regulators to establish rules and regulations to implement the new legislation. The CFTC has issued final regulations to implement significant aspects of the legislation, including new rules for the registration of swap dealers and major swap participants (and related definitions of those terms), definitions of the term “swap,” rules to establish the ability to rely on the commercial end-user exception from the central clearing and exchange trading requirements, requirements for reporting and recordkeeping, rules on customer protection in the context of cleared swaps, and position limits for swaps and

other transactions based on the price of certain reference contracts, some of which are referenced in our swap contracts. The position limits regulation has been vacated by a Federal court, and the CFTC is appealing that decision; accordingly, the effective date of these rules, if they are reinstated on appeal, or of replacement rules proposed and adopted by the CFTC, if applicable, is not currently known. Key regulations that have not yet been finalized include those establishing margin requirements for uncleared swaps, regulatory capital requirements for swap dealers and various trade execution requirements.

On December 13, 2012, the CFTC published final rules regarding mandatory clearing of certain interest rate swaps and certain index credit default swaps and setting compliance dates for different categories of market participants, the earliest of which is March 11, 2013. The CFTC has not yet proposed any rules requiring the clearing of any other classes of swaps, including physical commodity swaps. Although we expect to qualify for the end-user exception from the clearing requirement for our swaps, mandatory clearing requirements and revised capital requirements applicable to other market participants, such as swap dealers, may change the cost and availability of the swaps we use for hedging.

The CFTC’s swap regulations may require or cause our counterparties to collect margin from us, and if any of our swaps do not qualify for the commercial end-user exception, or if the cost of entering into uncleared swaps becomes prohibitive, we may be required to clear such transactions or execute them on a derivatives contract market or swap execution facility. The ultimate effect of the proposed new rules and any additional regulations on our business is uncertain. Of particular concern is whether our status as a commercial end-user will allow our derivative counterparties to not require us to post margin in connection with our commodity price risk management activities. The remaining final rules and regulations on major provisions of the legislation, such as new margin requirements, are to be established through regulatory rulemaking. Although we cannot predict the ultimate outcome of these rulemakings, new rules and regulations in this area, to the extent applicable to us or our derivative counterparties, may result in increased costs and cash collateral requirements for the types of derivative instruments we use to manage our financial and commercial risks related to fluctuations in commodity prices. Additional effects of the new regulations, including increased regulatory reporting and recordkeeping costs, increased regulatory capital requirements for our counterparties, and market dislocations or disruptions, among other consequences, could have an adverse effect on our ability to hedge risks associated with our business.

Additionally, in August 2012 the SEC adopted the Dodd-Frank Act requirement that registrants disclose certain payments made to the U.S. Federal government and foreign governments in connection with the commercial development of crude oil, natural gas or minerals. The deadline for implementing the new disclosures is May 31, 2014 for applicable payments made during the period from October 1, 2013 to December 31, 2013. We are working to develop a responsive approach for complying with the new disclosure requirements by the required deadline. We are also monitoring our operations to determine if any disclosure or reporting obligations arise under the conflict mineral rules established under the Dodd-Frank Act.

Inflation

In recent years prior to 2015 we have experienced inflationary pressure on technical staff compensation and the cost of oilfield services and equipment due to the increases in drilling activity particularly in the North region, and competitive pressures resulting from higherattractive crude oil pricesprices. However, in 2015 certain service and equipment costs decreased below 2014 levels as service providers reduced their costs in response to the significant decrease in commodity prices. If the existing commodity price environment persists or worsens in 2016 our industry may againexperience an additional decrease in certain service and equipment costs. However, inflationary pressures may return in the future.

future if commodity prices recover from current levels.

Non-GAAP Financial Measures

EBITDAX

We present EBITDAX throughout this Annual Report on Form 10-K, which is a non-GAAP financial measure. We define EBITDAX representsas earnings before interest expense, income taxes, depreciation, depletion, amortization and accretion, property impairments, exploration expenses, non-cash gains and losses resulting from the requirements of accounting for derivatives, and non-cash equity compensation expense.expense, and losses on extinguishment of debt. EBITDAX is not a measure of net income or operating cash flows as determined by U.S. GAAP.

Management believes EBITDAX is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. Further, we believe EBITDAX is a widely followed measure of operating performance and may also be used by investors to measure our ability to meet future debt service requirements, if any. We exclude the items listed above from net income (loss) and operating cash flows in arriving at EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired.

EBITDAX should not be considered as an alternative to, or more meaningful than, net income (loss) or operating cash flows as determined in accordance with U.S. GAAP or as an indicator of a company’s operating performance or liquidity. Certain items excluded from EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of EBITDAX. Our computations of EBITDAX may not be comparable to other similarly titled measures of other companies.

We believe EBITDAX is a widely followed measure of operating performance and may also be used by investors to measure our ability to meet future debt service requirements, if any. Our credit facility requires that we maintain a total funded debt to EBITDAX ratio of no greater than 4.0 to 1.0 on a rolling four-quarter basis. This ratio represents the sum of outstanding borrowings and letters of credit under our credit facility plus our note payable and Senior Note obligations, divided by total EBITDAX for the most recent four quarters. We were in compliance with this covenant at December 31, 2012. At that date, our total funded debt to EBITDAX ratio was 1.8 to 1.0. A violation of this covenant in the future could result in a default under our credit facility and such event could result in an acceleration of other outstanding indebtedness. In the event of such default, the lenders under our credit facility could elect to terminate their commitments thereunder, cease making further loans, and could declare all outstanding amounts, if any, to be due and payable. If we had any outstanding borrowings under our credit facility and such indebtedness were to be accelerated, our assets may not be sufficient to repay in full such indebtedness. Our credit facility defines EBITDAX consistently with the definition of EBITDAX utilized and presented by us.

The following table provides a reconciliation of our net income to EBITDAX for the periods presented.

PV-10

Our PV-10 value, a non-GAAP financial measure, is derived from the Standardized Measure of discounted future net cash flows, which is the most directly comparable financial measure computed using U.S. GAAP. PV-10 generally differs from Standardized Measure because it does not include the effects of income taxes on future net revenues. At December 31, 2012,2015, our PV-10 totaled approximately $13.3$8.0 billion. The Standardized Measure of our discounted future net cash flows was approximately $11.2$6.5 billion at December 31, 2012,2015, representing a $2.1$1.5 billion difference from PV-10 becausedue to the effect of thededucting estimated future income tax effect.taxes in arriving at Standardized Measure. We believe the presentation of PV-10 is relevant and useful to investors because it presents the discounted future net cash flows attributable to proved reserves held by companies without regard to the specific income tax characteristics of such entities and is a useful measure of evaluating the relative monetary significance of our crude oil and natural gas properties. Investors may utilize PV-10 as a basis for comparing the relative size and value of our proved reserves to other companies. PV-10 should not be considered as a substitute for, or more meaningful than, the Standardized Measure as determined in accordance with U.S. GAAP. Neither PV-10 nor Standardized Measure represents an estimate of the fair market value of our crude oil and natural gas properties.

Item 7A.Quantitative and Qualitative Disclosures About Market Risk

General.We are exposed to a variety of market risks including commodity price risk, credit risk, and interest rate risk. We seek to address these risks through a program of risk management which may include the use of derivative instruments.

Commodity Price Risk. Our primary market risk exposure is in the pricing applicable toprices we receive from sales of our crude oil and natural gas production. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot market prices applicable to our natural gas production. Pricing for crude oil and natural gas production has been volatile and unpredictable for several years, and we expect this volatility to continue in the future. The prices we receive for production depend on many factors outside of our control, including volatility in the differences between product prices at sales points and the applicable index price.prices. Based on our average daily production for the year ended December 31, 20122015 and excluding any effect of our derivative instruments in place, our annual revenue would increase or decrease by approximately $250$535 million for each $10.00 per barrel change in crude oil prices and $64$164 million for each $1.00 per Mcf change in natural gas prices.

To reduce price risk caused by these market fluctuations, from time to time we periodicallymay economically hedge a portion of our anticipated crude oil and natural gas production as part of our risk management program. In addition, we may utilize basis contracts to hedge the differential between derivative contract index prices and those of our physical pricing points. Reducing our exposure to price volatility helps ensure we have adequatesecure funds availableto be used for our capital program. Our decision on the quantity and price at which we choose to hedge our production is based in part on our view of current and future market conditions. We may choose not to hedge future production if the pricing environment for certain time periods is deemed to be unfavorable. Additionally, we may choose to liquidate existing derivative positions prior to the expiration of their contractual maturities in order to monetize favorable gain positions for the purpose of funding our capital program. While hedging, if utilized, limits the downside risk of adverse price movements, it also limits future revenues from upward price movements.

Our crude oil production and sales for 2016 and beyond are currently unhedged and directly exposed to continued volatility in crude oil market prices, whether favorable or unfavorable.

Changes in commodity futures price stripsnatural gas prices during the year ended December 31, 20122015 had an overall net positivefavorable impact on the fair value of our derivative contracts.instruments. For the year ended December 31, 2012,2015, we reported an unrealized non-cash mark-to-market gainrecognized cash gains on derivatives of $199.7$69.6 million the financial impact of which was partially offset by realized lossesand non-cash mark-to-market gains on derivatives of $45.7$21.5 million.
The fair value of our natural gas derivative instruments at December 31, 20122015 was a net asset of $35.4$101 million. This mark-to-market net asset relates to derivative instruments with various terms that are scheduled to be realized over the period from January 2013 through December 2015. Over this period, actual realized derivative settlements may differ significantly, either positively or negatively, from the unrealized mark-to-market valuation at December 31, 2012. An assumed increase in the forward commodity prices used in the year-end valuation of our derivative instrumentsnatural gas derivatives of $10.00 per barrel for crude oil and $1.00 per MMBtu for natural gas would change our derivative valuation to a net liability of approximately $398$101 million at December 31, 2012.2015. Conversely, an assumed decrease in forward commodity prices of $10.00 per barrel for crude oil and $1.00 per MMBtu for natural gas would increase our netnatural gas derivative asset to approximately $461$302 million at December 31, 2012.

Derivative Instruments appearingfor further discussion of our hedging activities, including a summary of derivative contracts in this Annual Report.place as of December 31, 2015.

Credit Risk. We monitor our risk of loss due to non-performance by counterparties of their contractual obligations. Our principal exposure to credit risk is through the sale of our crude oil and natural gas production, which we market to energy marketing companies, refineriescrude oil refining companies, and affiliatesnatural gas gathering and processing companies ($480.3379 millionin receivables at December 31, 2012)2015), our joint interest receivables ($356.8232 millionat December 31, 2012)2015), and counterparty credit risk associated with our derivative instrument receivables ($50.6108 million at December 31, 2012)2015).

We monitor our exposure to counterparties on crude oil and natural gas sales primarily by reviewing credit ratings, financial statements and payment history. We extend credit terms based on our evaluation of each counterparty’s credit worthiness. We have not generally required our counterparties to provide collateral to supportsecure crude oil and natural gas sales receivables owed to us. Historically, our credit losses on crude oil and natural gas sales receivables have been immaterial.

Joint interest receivables arise from billing the individuals and entities whichwho own a partial interest in the wells we operate. These individuals and entities participate in our wells primarily based on their ownership in leases included in units on which we wish to drill. We can do very little to choose who participates in our wells. In order to minimize our exposure to credit risk we generally request prepayment of drilling costs where it is allowed by contract or state law. For such prepayments, a liability is recorded and subsequently reduced as the associated work is performed. This liability was $30.4$50 million as ofat December 31, 2012,2015, which will be used to offset future capital costs when billed. In this manner, we reduce credit risk. We alsomay have the right to place a lien on our co-owners interest in the well to redirect production proceeds in order to secure payment or, if necessary, foreclose on the interest. Historically, our credit losses on joint interest receivables have been immaterial.


70



Our use of derivative instruments involves the risk that our counterparties will be unable to meet their commitments under the arrangements. We manage this risk by using multiple counterparties who we consider to be financially strong in order to minimize our exposure to credit risk with any individual counterparty. Substantially all of our derivative contracts are with parties that are lenders (or affiliates of lenders) under our credit facility.

Interest Rate Risk. Our exposure to changes in interest rates relates primarily to any variable-rate borrowings we may have outstanding from time to time under our revolving credit facility.facility and three-year term loan. We manage our interest rate exposure by monitoring both the effects of market changes in interest rates and the proportion of our debt portfolio that is variable-rate versus fixed-rate debt. We may utilize interest rate derivatives to alter interest rate exposure in an attempt to reduce interest rate expense related to existing debt issues. Interest rate derivatives may be used solely to modify interest rate exposure and not to modify the overall leverage of the debt portfolio. We currently have no interest rate derivatives.
We had $840 millionan aggregate of $1.33 billion of variable rate borrowings outstanding borrowings underon our revolving credit facility and three-year term loan at February 15, 2013.19, 2016. The impact of a 1% increase in interest rates on this amount of debt would result in increased interest expense of approximately $8.4$13.3 million per year and a $5.2an $8.2 million decrease in net income per year. Our credit facility matures on July 1, 2015 and the weighted-average interest rate on outstanding borrowings at February 15, 2013 was 2.0%.

Changes in interest rates affect the amounts we pay on borrowings under our revolving credit facility.facility and three-year term loan. Such borrowings bear interest at market-based interest rates plus a margin that is based on the terms of the borrowing and the credit ratings assigned to our senior, unsecured, long-term indebtedness. In February 2016, our corporate credit rating was downgraded by S&P and Moody's in response to weakened oil and gas industry conditions and resulting revisions made to rating agency commodity price assumptions. These downgrades will cause the interest rates on our revolving credit facility borrowings and three-year term loan to increase by 0.250% and 0.125%, respectively. All of our other long-term indebtedness is fixed rate and does not expose us to the risk of cash flow loss due to changes in market interest rates. However, changes in interest rates do affect the fair values of our senior notes and note payable.

Note 1. Organization and Summary of Significant Accounting Policies

Description of the Company

Continental Resources, Inc. (the “Company”) was originally formed in 1967 and is incorporated under the laws of the State of Oklahoma. The Company was originally formed in 1967 to explore for, develop and produceCompany's principal business is crude oil and natural gas. Continental’sgas exploration, development and production with properties areprimarily located in the North, South, and East regions of the United States. The North region consists of properties north of Kansas and west of the Mississippi River and includes North Dakota Bakken, Montana Bakken, and the Red River units. The South region includes Kansas and all properties south of Kansas and west of the Mississippi River including various plays in the SouthSCOOP (South Central Oklahoma Oil Province,Province), STACK (Sooner Trend Anadarko Canadian Kingfisher), Northwest Cana and Arkoma Woodford plays inareas of Oklahoma. In December 2012, the Company sold its producing properties in the East region. SeeNote 13. Property Acquisitions and Dispositions for further discussion. The Company’s remaining East region properties areis comprised of undeveloped leasehold acreage east of the Mississippi River.

TheRiver with no current drilling or production operations.

A substantial portion of the Company’s operations are geographically concentrated in the North region, with that region comprising approximately 76%68% of the Company’s crude oil and natural gas production and approximately 77% of its crude oil and natural gas revenues for the year ended December 31, 2012. Additionally, as2015. The Company's principal producing properties in the North region are located in the Bakken field of North Dakota and Montana. As of December 31, 20122015, approximately 82%58% of the Company’s estimated proved reserves were located in the North region.

In recent years, the Company has significantly expanded its activity in the South region with its discovery of the SCOOP play and its increased activity in the Northwest Cana and STACK plays. The South region comprised approximately 32% of the Company's crude oil and natural gas production, 23% of its crude oil and natural gas revenues, and 42% of its estimated proved reserves at December 31, 2015.

The Company has focused its operations on the exploration and development of crude oil since the 1980s. For the year ended December 31, 2012,2015, crude oil accounted for approximately 70%66% of the Company’s crude oil and natural gastotal production and approximately 89%85% of its crude oil and natural gas revenues.

Crude oil represents approximately 57% of the Company's estimated proved reserves as of December 31, 2015.

Basis of presentation of consolidated financial statements

The consolidated financial statements include the accounts of Continental Resources, Inc.the Company and its subsidiaries. Allsubsidiaries, all of which are 100% owned, after all significant intercompany balancesaccounts and transactions have been eliminated upon consolidation.

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure and estimation of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates. The most significant of the estimates and assumptions that affect reported results are the estimates of the Company’s crude oil and natural gas reserves, which are used to compute depreciation, depletion, amortization and impairment of proved crude oil and natural gas properties. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation in accordance with U.S. GAAP have been included in these consolidated financial statements.

Revenue recognition

Crude oil and natural gas sales result from interests owned by the Company in crude oil and natural gas properties. Sales of crude oil and natural gas produced from crude oil and natural gas operations are recognized when the product is delivered to the purchaser and title transfers to the purchaser. Payment is generally received one to three months after the sale has occurred. Each month the Company estimates the volumes sold and the price at which they were sold to record revenue. The following table shows the amounts of estimated crude oil and natural gas sales recorded as of December 31 for each indicated year.

Variances between estimated revenues and actual amounts received are recorded in the month payment is received and are included in the consolidated statements of income under the caption “Revenues—Crude Oil and Natural Gas Sales”. These variances have historically not been material. The Company uses the sales method of accounting for natural gas imbalances in those circumstances where it has under-produced or over-produced its ownership percentage in a property. Under this method, a receivable or payable is recognized only to the extent an imbalance cannot be recouped from the reserves in the underlying properties. The Company’s aggregate imbalance positions at December 31, 20122015 and 20112014 were not material.

Cash and cash equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company maintains its cash and cash equivalents in accounts that may not be federally insured. As of December 31, 2012,2015, the Company had cash deposits in excess of federally insured amounts of approximately $35.2$10.7 million. The Company has not experienced any losses in such accounts and believes it is not exposed to significant credit risk in this area.

Accounts receivable

The Company operates exclusively in crude oil and natural gas exploration and production related activities. Receivables arising from crude oil and natural gas sales and joint interest receivables are generally unsecured. Accounts receivable are due within 30 days and are considered delinquent after 60 days. The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time accounts are past due, the Company’s history of losses, and the customer or working interest owner’s ability to pay. The Company writes off specific receivables when they become uncollectiblenoncollectable and any payments subsequently received on those receivables are credited to the allowance for doubtful accounts. Write-offs of uncollectiblenoncollectable receivables have historically not been material.

Concentration of credit risk

The Company is subject to credit risk resulting from the concentration of its crude oil and natural gas receivables with several significant purchasers. For the years ended December 31, 2012, 2011 and 2010, crude oil and natural gas sales to the Company’s largest purchaser accounted for approximately 21%, 41% and 57% of total crude oil and natural gas sales, respectively. Additionally, for the year ended December 31, 20122015, sales to the Company’s second largest purchaser accounted for approximately 11% of its total crude oil and natural gas sales. No other purchasers accounted for more than 10% of the Company’s total crude oil and natural gas sales for those three years.2015. The Company does not require collateral and does not believe the loss of any single purchaser would materially impact its operating results, as crude oil and natural gas are fungible products with well-established markets and numerous purchasers in various regions.
Inventories
Inventory is comprised of crude oil held in storage or as line fill in pipelines and tubular goods and equipment to be used in the Company’s operating regions.

Crude oil and natural gas properties

The Company uses the successful efforts method of accounting for crude oil and natural gas properties whereby costs incurred to acquire mineral interests in crude oil and natural gas properties, to drill and equip exploratory wells that find proved reserves, to drill and equip development wells, and expenditures for enhanced recovery operations are capitalized. Geological and geophysical costs, seismic costs incurred for exploratory projects, lease rentals and costs associated with unsuccessful exploratory wells or projects are expensed as incurred. Costs of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. To the extent a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between capitalized development costs and exploration expense. Maintenance, repairs and costs of injection are expensed as incurred, except that the costs of replacements or renewals that expand capacity or improve production are capitalized.

Under the successful efforts method of accounting, the Company capitalizes exploratory drilling costs on the balance sheet pending determination of whether the well has found proved reserves in economically producible quantities. The Company capitalizes costs associated with the acquisition or construction of support equipment and facilities with the drilling and development costs to which they relate. If proved reserves are found by an exploratory well, the associated capitalized costs become part of well equipment and facilities. However, if proved reserves are not found, the capitalized costs associated with the well are expensed, net of any salvage value. Total capitalized exploratory drilling costs pending the determination

Consolidated Financial Statements



Production expenses are those costs incurred by the Company to operate and maintain its crude oil and natural gas properties and associated equipment and facilities. Production expenses include labor costs to operate the Company’s properties, repairs and maintenance, waste water disposal costs, and materials and supplies utilized in the Company’s operations.

Service property and equipment consist primarily of automobiles and aircraft; machinery and equipment; gathering systems; storage tanks; office and computer equipment, software, furniture and fixtures, automobiles, machinery and equipment, office equipment, computer equipment and software,fixtures; and buildings and improvements. Major renewals and replacements are capitalized and stated at cost, while maintenance and repairs are expensed as incurred.

Depreciation and amortization of service property and equipment are provided in amounts sufficient to expense the cost of depreciable assets to operations over their estimated useful lives using the straight-line method. The estimated useful lives of service property and equipment are as follows:

Depreciation, depletion and amortization

Depreciation, depletion and amortization of capitalized drilling and development costs of producing crude oil and natural gas properties, including related support equipment and facilities, are computed using the unit-of-production method on a field basis based on total estimated proved developed crude oil and natural gas reserves. Amortization of producing leaseholds is based on the unit-of-production method using total estimated proved reserves. In arriving at rates under the unit-of-production method, the quantities of recoverable crude oil and natural gas reserves are established based on estimates made by the Company’s internal geologists and engineers and external independent reserve engineers. Upon sale or retirement of properties, the cost and related accumulated depreciation, depletion and amortization are eliminated from the accounts and the resulting gain or loss, if any, is recognized. Unit of production rates are revised whenever there is an indication of a need, but at least in conjunction with semi-annual reserve reports. Revisions are accounted for prospectively as changes in accounting estimates.

Asset retirement obligations

The Company accounts for its asset retirement obligations by recording the fair value of a liability for an asset retirement obligation in the period in which a legal obligation is incurred and a corresponding increase in the carrying amount of the related long-lived asset. Subsequently, the capitalized asset retirement costs are charged to expense through the depreciation, depletion and amortization of crude oil and natural gas properties and the liability is accreted to the expected future abandonment cost ratably over the related asset’s life.

Asset impairment

Proved crude oil and natural gas properties are reviewed for impairment on a field-by-field basis each quarter, or when events and circumstances indicate a possible decline in the recoverability of the carrying value of such field.quarter. The estimated future cash flows expected in connection with the field are compared to the carrying amount of the field to determine if the carrying amount is recoverable. If the carrying amount of the field exceeds its estimated undiscounted future cash flows, the carrying amount of the field is reduced to its estimated fair value. Due to the unavailability of relevant comparable market data, a discounted cash flow method is used to determine the fair value of proved properties. The discounted cash flow method estimates future cash flows based on management’s estimates of future crude oil and natural gas production, commodity prices based on commodity futures price strips, operating and development costs, and a risk-adjusted discount rate.

Non-producing crude oil and natural gas properties primarily consist of undeveloped leasehold costs and costs associated with the purchase of certain proved undeveloped reserves. Individually significantImpairment losses for non-producing properties if any, are assessed for impairment on a property-by-property basis and, if the assessment indicates an impairment, a loss is recognized by providing a valuation allowance consistent with the level at which impairment was assessed. For individually insignificant non-producing properties, impairment losses are recognized by amortizing the portion of the properties’ costs which management estimates will not be transferred to proved properties over the lives of the leases based on drilling plans, experience of successful drilling, and the average holding period. The Company’s impairment assessments are affected by economic factors such as the results of exploration activities, commodity price outlooks, anticipated drilling programs, remaining lease terms, and potential shifts in business strategy employed by management.

Derivative instruments

The Company is required to recognizerecognizes its derivative instruments on the balance sheet as either assets or liabilities measured at fair value with such amounts classified as current or long-term based on anticipatedcontractual settlement dates. The accounting for the changes in fair value of a derivative depends on the intended use of the derivative and resulting designation. The Company has not designated its derivative instruments as hedges for accounting purposes and, as a result, marks its derivative instruments to fair value and recognizes the realized and unrealized changes in fair value in the consolidated statements of comprehensive income (loss) under the caption “Gain (loss) on derivative instruments, net.”

Fair value of financial instruments

The Company’s financial instruments consist primarily of cash, trade receivables, trade payables, derivative instruments and long-term debt. The carrying values of cash, trade receivables and trade payables are considered to be representative of their respective fair values due to the short term maturity of those instruments. The fair value of derivative contracts is based upon various factors, including commodity exchange prices, over-the-counter quotations, and, in the case of collars, volatility, the risk-free interest rate, and the time to expiration. SeeNote 5. Derivative Instruments for quantification of the fair value of the Company’s derivative instruments at December 31, 2012 and 2011.

Long-term debt consists of the Company’s Notes, its note payable, and borrowings on its revolving credit facility. The fair values of the Notes are based on quoted market prices. The fair value of the note payable is determined using a discounted cash flow approach based on the interest rate and payment terms of the note payable and an assumed discount rate. The fair value of credit facility borrowings approximates carrying value based on borrowing rates available to the Company for bank loans with similar terms and maturities. SeeNote 6. Fair Value Measurements for a discussion of the methods used to determine fair value for the Company's financial instruments and the quantification of the fair value of the Company’sfor its derivatives and long-term debt obligations at December 31, 20122015 and 2011.2014.

Income taxes

Income taxes are accounted for using the liability method under which deferred income taxes are recognized for the future tax effects of temporary differences between financial statement carrying amounts and the tax basis of existing assets and liabilities using the enacted statutory tax rates in effect at year-end. The effect on deferred taxes for a change in tax rates is recognized in income in the period that includes the enactment date. The Company’s policy is to recognize penalties and interest related to unrecognized tax benefits, if any, in income tax expense. A valuation allowance for deferred tax assets is recorded when it is more likely than not that the benefit from the deferred tax asset will not be realized.

(1)During the year ended December 31, 2015, the Company had a net loss and therefore the potential dilutive effect of approximately 1,567,000 weighted average restricted shares were not included in the calculation of diluted net loss per share for 2015 because to do so would have been anti-dilutive to the computations.
Foreign currency translation
In 2014, the Company initiated exploratory drilling activities in Canada through a 100%-owned Canadian subsidiary. The Company has designated the Canadian dollar as the functional currency for its Canadian operations. Adjustments resulting from the process of translating foreign functional currency financial statements into U.S. dollars are included in "Accumulated other comprehensive loss" within shareholders’ equity on the consolidated balance sheets.

New accounting pronouncements
In April 2015, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). The new standard requires debt issuance costs related to a recognized term debt liability, such as the Company's senior notes, three-year term loan and note payable, be presented in the balance sheet as a direct deduction from the carrying amount of that term debt liability, consistent with the presentation of a debt discount. Under previous guidance, debt issuance costs were required to be presented in the balance sheet as an asset. The new standard does not affect the existing recognition and measurement guidance for debt issuance costs. The new standard is effective for annual and interim periods beginning after December 15, 2015, with early adoption permitted.
The Company early adopted ASU 2015-03 as of June 30, 2015 on a retrospective basis to all prior balance sheet periods presented. As a result of the adoption, the Company reclassified unamortized debt issuance costs associated with its senior notes and note payable, which totaled $65.7 million and $69.0 million as of June 30, 2015 and December 31, 2014, respectively, from "Other noncurrent assets" to a reduction of "Long-term debt, net of current portion" on the consolidated balance sheets. Unamortized debt issuance costs reflected as a reduction of long-term debt subsequently totaled $64.0 million as of December 31, 2015, inclusive of costs incurred upon execution of the Company's new term loan in November 2015 as discussed in Note 7. Long-Term Debt. Adoption of ASU 2015-03 had no impact on the Company's current and previously reported shareholders' equity, results of operations, or cash flows. The December 31, 2014 carrying amounts for the Company's senior notes and note payable presented throughout this report on Form 10-K have been adjusted to reflect the retroactive adoption of ASU 2015-03. Unamortized debt issuance costs associated with the Company's revolving credit facility, which amounted to $7.8 million and $7.0 million as of December 31, 2015 and 2014, respectively, were not reclassified and remain reflected in "Other noncurrent assets" on the consolidated balance sheets.
In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which requires entities with a classified balance sheet to present all deferred tax assets and deferred tax liabilities as noncurrent instead of separating deferred taxes into current and noncurrent amounts. The standard will be effective for public companies for annual and interim periods beginning after December 15, 2016, with early adoption permitted. The Company early adopted ASU 2015-17 as of December 31, 2015 on a retrospective basis to all prior balance sheet periods presented. As a result of the adoption, the Company reclassified $36.2 million and $145.3 million as of December 31, 2015 and 2014, respectively, from "Accrued liabilities and other" to “Deferred income tax liabilities, net” on the consolidated balance sheets. Adoption of ASU 2015-17 had no impact on the Company's current and previously reported shareholders' equity, results of operations, or cash flows. The affected prior period deferred income tax account balances presented throughout this report on Form 10-K have been adjusted to reflect the retroactive adoption of ASU 2015-17.

Note 5. Derivative Instruments

The Company is required to recognizerecognizes all derivative instruments on the balance sheet as either assets or liabilities measured at fair value. The Company has not designated its derivative instruments as hedges for accounting purposes and, as a result, marks its derivative instruments to fair value and recognizes the realized and unrealized changes in fair value in the consolidated statements of comprehensive income (loss) under the caption “Gain (loss) on derivative instruments, net.”

The Company has utilizedmay utilize swap and collar derivative contracts to economically hedge against the variability in cash flows associated with the forecasted sale of future crude oil and natural gas production. While the use of these derivative instruments limits the downside risk of adverse price movements, their use also limits future revenues from upward price movements.

With respect to a fixed price swap contract, the counterparty is required to make a payment to the Company if the settlement price for any settlement period is less than the swap price, and the Company is required to make a payment to the counterparty if the settlement price for any settlement period is greater than the swap price. For a collar contract, the counterparty is required to make a payment to the Company if the settlement price for any settlement period is below the floor price, and the Company is required to make a payment to the counterparty if the settlement price for any settlement period is above the ceiling price, and neitherprice. Neither party is required to make a payment to the other party if the settlement price for any settlement period is between the floor price and the ceiling price.

All of the Company’s derivative contracts are carried at their fair value in the consolidated balance sheets under the captions “Derivative assets”, “Noncurrent derivative assets”, “Derivative liabilities”, and “Noncurrent derivative liabilities”. Derivative assets and liabilities with the same counterparty and subject to contractual terms which provide for net settlement are reported on a net basis in the consolidated balance sheets. The Company’sCompany's derivative contracts are settled based upon reported settlement prices on commodity exchanges, with crude oil derivative settlements based on NYMEX West Texas Intermediate (“WTI”) pricing or Inter-Continental Exchange (“ICE”("ICE") pricing for Brent crude oil and natural gas derivative settlements based on NYMEX Henry Hub pricing. The estimated fair value of derivative contracts is based upon various factors, including commodity exchange prices, over-the-counter quotations, and, in the case of collars and written call options, volatility, the risk-free interest rate, and the time to expiration. The calculation of the fair value of collars and written call options requires the use of an option-pricing model. SeeNote 6. Fair Value Measurements.

Note 6. Fair Value Measurements

The Company follows Accounting Standards Codification Topic 820,Fair Value Measurements and Disclosures, which establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:

Level 1: Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.

Level 3: Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value.

A financial instrument’s categorization within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Level 1 inputs are given the highest priority in the fair value hierarchy while Level 3 inputs are given the lowest priority. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement of assets and liabilities

Continental Resources, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

within the levels of the hierarchy. As Level 1 inputs generally provide the most reliable evidence of fair value, the Company uses Level 1 inputs when available. The Company’s policy is to

Continental Resources, Inc. and Subsidiaries
Notes to Consolidated Financial Statements


recognize transfers between the hierarchy levels as of the beginning of the reporting period in which the event or change in circumstances caused the transfer.

Assets and liabilities measured at fair value on a recurring basis

Certain assets and liabilities

The Company's derivative instruments are reported at fair value on a recurring basis, including the Company’s derivative instruments.basis. In determining the fair values of fixed price swaps and basis swaps, a discounted cash flow method is used due to the unavailability of relevant comparable market data for the Company’s exact contracts. The discounted cash flow method estimates future cash flows based on quoted market prices for forward commodity prices observable inputs relating to basis differentials and a risk-adjusted discount rate. The fair values of fixed price swaps and basis swaps are calculated mainly using significant observable inputs (Level 2). Calculation of the fair values of collar contractscollars and written call options requires the use of an industry-standard option pricing model that considers various inputs including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. These assumptions are observable in the marketplace or can be corroborated by active markets or broker quotes and are therefore designated as Level 2 within the valuation hierarchy. The Company’s calculation of fair value for each of its derivative positions is compared to the counterparty valuation for reasonableness.

Assets measured at fair value on a nonrecurring basis

Certain assets are reported at fair value on a nonrecurring basis in the consolidated financial statements. The following methods and assumptions were used to estimate the fair values for those assets.

Notes to Consolidated Financial Statements

Asset Impairmentsimpairments Proved crude oil and natural gas properties are reviewed for impairment on a field-by-field basis each quarter, or when events and circumstances indicate a possible decline in the recoverability of the carrying value of such field.quarter. The estimated future cash flows expected in connection with the field are compared to the carrying amount of the field to determine if the carrying amount is recoverable. If the carrying amount of the field exceeds its estimated undiscounted future cash flows, the carrying amount of the field is reduced to its estimated fair value. Due to the unavailability of relevant comparable market data, a discounted cash flow method is used to determine the fair value of proved properties. The discounted cash flow method estimates future cash flows based on management’sthe Company's estimates of future crude oil and natural gas production, commodity prices based on commodity futures price strips, operating and development costs, and a risk-adjusted discount rate. The fair value of proved crude oil and natural gas properties is calculated using significant unobservable inputs (Level 3). The following table sets forth quantitative information about the significant unobservable inputs used by the Company to calculate the fair value of proved crude oil and natural gas properties using a discounted cash flow method.

Unobservable inputs to the fair value assessment are reviewed quarterly and are revised as warranted based on a number of factors, including reservoir performance, new drilling, crude oil and natural gas prices, changes in costs, technological advances, new geological or geophysical data, or other economic factors. Fair value measurements of proved properties are reviewed and approved by certain members of the Company’s management.

Impairments of proved properties amounted to $4.3$138.9 million for the year ended December 31, 2012, all2015 resulting from declines in commodity prices that indicated the carrying amounts for certain fields were not recoverable. The 2015 impairments reflect fair value adjustments primarily concentrated in an emerging area with minimal production and costly reserve additions ($42.5 million), the Medicine Pole Hills units ($32.5 million), the Buffalo Red River units ($26.3 million), non-Bakken areas of which was recognizedNorth Dakota and Montana ($8.2 million), Wyoming properties ($17.9 million), and various legacy areas in the second quarter of the year.South region ($11.4 million).

Certain unproved crude oil and natural gas properties were impaired during 2012,the years ended December 31, 2015, 2014, and 2013, reflecting recurring amortization of undeveloped leasehold costs on properties that managementthe Company expects will not be transferred to proved properties over the lives of the leases based on drilling plans, experience of successful drilling, and the average holding period.

The fair valuevalues of the revolving credit facility approximates itsborrowings and the term loan approximate carrying value based on borrowing rates available to the Company for bank loans with similar terms and maturities and isare classified as Level 2 in the fair value hierarchy.

The fair value of the note payable is determined using a discounted cash flow approach based on the interest rate and payment terms of the note payable and an assumed discount rate. The fair value of the note payable is significantly influenced by the discount rate assumption, which is derived by the Company and is unobservable. Accordingly, the fair value of the note payable is classified as Level 3 in the fair value hierarchy.

The fair values of the 8 1/4% Senior Notes due 2019 (the “2019 Notes”), the 7 3/8%7.375% Senior Notes due 2020 (the “2020(“2020 Notes”), the 7 1/8%7.125% Senior Notes due 2021 (the “2021(“2021 Notes”) and, the 5% Senior Notes due 2022 (the “2022(“2022 Notes”), the 4.5% Senior Notes due 2023 (“2023 Notes”), the 3.8% Senior Notes due 2024 (“2024 Notes”), and the 4.9% Senior Notes due 2044 (“2044 Notes”) are based on quoted market prices and, accordingly, are classified as Level 1 in the fair value hierarchy.

The carrying values of all classes of cash and cash equivalents, trade receivables, and trade payables are considered to be representative of their respective fair values due to the short term maturities of those instruments.

Revolving credit facility

The Company has an unsecured revolving credit facility, maturing on May 16, 2019, with aggregate commitments totaling $2.75 billion at December 31, 2015, which may be increased up to a total of $4.0 billion upon agreement between the Company and participating lenders.
The Company had $595$853 million of outstanding borrowings at December 31, 2012 on its credit facility, which matures on July 1, 2015. At December 31, 2011, the Company had $358and $165 million of outstanding borrowings on its credit facility. The credit facility had aggregate commitments of $1.5 billion and a borrowing base of $3.25 billion at December 31, 2012, subject to semi-annual redetermination. The most recent borrowing base redetermination was completed in December 2012, whereby2015 and 2014, respectively. Borrowings bear interest at market-based interest rates plus a margin that is based on the lenders approved an increase in the Company’s borrowing base from $2.75 billion to $3.25 billion.

Borrowings under the facility bearCompany's senior, unsecured, long-term indebtedness. The weighted-average interest rate on outstanding borrowings at a rate per annum equal to the London Interbank Offered Rate (LIBOR) for one, two, three or six months, as elected by the Company, plus a margin ranging from 150 to 250 basis points, depending on the percentage of the borrowing base utilized, or the lead bank’s reference rate (prime) plus a margin ranging from 50 to 150 basis points. Credit facility borrowings are required to be secured by the Company’s interest in at least 80% (by value) of all of its proved reserves and associated crude oil and natural gas properties unless the Collateral Coverage Ratio, as defined in the amended credit agreement, is greater than or equal to 1.75 to 1.0, in which case the 80% requirement will not apply.

On August 16, 2012, the Company issued an additional $1.2 billion of 5% Senior Notes due 2022 (the “New Notes”). The New Notes were issued pursuant to the indenture applicable to the $800 million of 5% Senior Notes previously issued on March 8, 2012, resulting in a total of $2.0 billion aggregate principal amount of 5% Senior Notes due 2022 being issued under that indenture. The New Notes have substantially identical terms to the $800 million of Senior Notes originally issued in March 2012. The New Notes were sold at 102.375% of par value, resulting in net proceeds of approximately $1.21 billion after deducting the initial purchasers’ fees. The Company used a portion of the net proceeds from the offering to repay all amounts then outstanding under its credit facility and used the remaining net proceeds to fund a portion of its 2012 capital budget and for general corporate purposes.

2014 Redemption of Senior Notes
In July 2014, the Company redeemed its then outstanding 8.25% Senior Notes due 2019 ("2019 Notes") using a portion of the proceeds from the May 2014 issuances of 2024 Notes and 2044 Notes.

The 2019 Notes were redeemed for $317.5 million, representing a make-whole amount calculated in accordance with the terms of the 2019 Notes and related indenture. The Company recognized a pre-tax loss of $24.5 million related to the redemption, which included the make-whole premium and the write-off of deferred financing costs and unaccreted debt discount and is reflected under the caption “Loss on extinguishment of debt" in the consolidated statements of comprehensive income (loss) for the year ended December 31, 2014.

Term loan
In November 2015, the Company borrowed $500 million under a three-year term loan agreement, the proceeds of which were used to repay a portion of the borrowings then outstanding on the Company's revolving credit facility. The term loan matures in full on November 4, 2018 and bears interest at a variable market-based interest rate plus a margin that is based on the terms of the borrowing and the credit ratings assigned to the Company's senior, unsecured, long-term indebtedness. The interest rate on the term loan at December 31, 2015 was 1.8%.
The term loan contains certain restrictive covenants including a requirement that the Company maintain a consolidated net debt to total capitalization ratio of no greater than 0.65 to 1.0, consistent with the covenant requirement in the Company's revolving credit facility. The Company was in compliance with this covenant at December 31, 2015.

The remainder of the state net operating loss carryforwards will begin expiring in 2017. The carryforwards have expiration periods that vary according to state jurisdiction. The Company has alternative minimum tax credit carryforwards of $27.0$41 million that have no expiration date. Any available statutory depletion carryforwardcarryforwards will be recognized when realized. The Company files income tax returns in the U.S. Federal jurisdictionfederal, U.S. state and various stateCanadian jurisdictions.

2012.
The Company recorded valuation allowances of $13.5 million and $4.4 million against Canadian deferred tax assets for the years ended December 31, 2015 and 2014, respectively, which resulted in a cumulative valuation allowance of $17.9 million as of December 31, 2015. Our Canadian subsidiary has generated operating loss carryforwards for which we do not believe we will realize a benefit. The amount of deferred tax assets considered realizable, however, could change if our subsidiary generates taxable income.

Note 10. Commitments and Contingencies

Included below is a discussion of various future commitments of the Company as of December 31, 2015. The commitments under these arrangements are not recorded in the accompanying consolidated balance sheets.
Drilling commitments – As of December 31, 2012,2015, the Company had drilling rig contracts with various terms extending through August 2014. These contracts were entered into in the ordinary course of businessto year-end 2019 to ensure rig availability to allow the Company to execute its business objectives in its key strategic plays.operating areas. Future commitments as of December 31, 20122015 total approximately $95$422 million, of which $80$200 million is expected to be incurred in 2013 and $152016, $136 million in 2014. These drilling commitments are not recorded2017, $62 million in the accompanying consolidated balance sheets.

Fracturing2018, and well stimulation service agreement – The Company has an agreement with a third party whereby the third party will provide, on a take-or-pay basis, hydraulic fracturing services and related equipment to service certain of the Company’s properties$24 million in North Dakota and Montana. The agreement has a term of three years, beginning in October 2010, with two one-year extensions available to the Company at its discretion. Pursuant to the take-or-pay provisions, the Company is to pay a fixed rate per day for a minimum number of days per calendar quarter over the three-year term regardless of whether the services are provided. The agreement also stipulates the Company will bear the cost of certain products and materials used. Future commitments remaining as of December 31, 2012 amount to approximately $17 million, all of which is expected to be incurred in 2013.2019.

Continental Resources, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

Since the inception of this agreement, the Company has been using the services more than the minimum number of days each quarter. The commitment under this agreement is not recorded in the accompanying consolidated balance sheets.

Pipeline transportation commitments – The Company has entered into firm transportation commitments to guarantee pipeline access capacity totaling 15,000 barrels ofon operational crude oil per day on operational pipelines in order to reduce the impact of possible production curtailments that may arise due to limited transportation capacity.and natural gas pipelines. The commitments, which have 5-yearvarying terms extending as far as November 2017,2027, require the Company to pay varying per-barrelper-unit transportation charges regardless of the amount of pipeline capacity used. Future commitments remaining as of December 31, 20122015 under the operational pipeline transportation arrangements amount to approximately $55 million,$1.0 billion, of which $13 million is expected to be incurred annually in years 2013, 2014 and 2015, $10 million in 2016, and $5 million in 2017.

Further, the Company is a party to additional 5-year firm transportation commitments for future pipeline projects being considered for development that are not yet operational. Such projects require the granting of regulatory approvals or otherwise require significant additional construction efforts by our counterparties before being completed. Future commitments under the non-operational arrangements total approximately $1.0 billion at December 31, 2012, representing aggregate transportation charges expected to be incurred over the 5-year terms of the arrangements assuming the proposed pipeline projects are completed and become operational. The timing of the commencement of pipeline operations is not known due to uncertainties involving matters such as regulatory approvals, resolution of legal and environmental disputes, construction progress and the ultimate probability of pipeline completion. Accordingly, the timing of the Company’s obligations under these non-operational arrangements cannot be predicted with certainty and may not be incurred on a ratable basis over a calendar year or may not be incurred at all. Although timing is uncertain, the Company’s obligations under these arrangements are not expected to begin until at least 2014.

Rail transportation commitments –The Company has entered into firm transportation commitments to guarantee capacity on rail transportation facilities in order to reduce the impact of possible production curtailments that may arise due to limited transportation capacity. The rail commitments have various terms extending through December 2015 and require the Company to pay varying per-barrel transportation charges on volumes ranging from 2,500 to 10,000 barrels of crude oil per day regardless of the amount of rail capacity used. Future commitments remaining as of December 31, 2012 under the rail transportation arrangements amount to approximately $52 million, of which $35$215 million is expected to be incurred in 2013, $102016, $212 million in 2014, and $72017, $207 million in 2015.2018, $154 million in 2019, $47 million in 2020, and $170 million thereafter.

Further, the Company was a party to a five-year firm transportation commitment (the "Agreement") for a future crude oil pipeline project being considered for development that is not yet operational. The project requires the granting of regulatory approvals and requires additional construction efforts by the counterparty before being completed. The project has faced significant delays and has failed to gain the necessary permits and approvals. As a result of the persistent delays and lack of regulatory approval, the Agreement’s basic assumptions and purpose have become commercially impracticable. Accordingly, in 2015 the Company provided a shipper termination notice pursuant to the Agreement and formally provided the counterparty with the Company’s termination of the Agreement in its entirety. The Company's previously disclosed commitments under the Agreement totaled approximately $260 million, which are no longer expected to be incurred.
The Company’s pipeline and rail transportation commitments are for crude oil production primarily in the North region where the Company allocates a significant portion of its capital expenditures. The commitments under these arrangements are not recorded in the accompanying consolidated balance sheets.region. The Company is not committed under these contracts or any other existing contract, to deliver fixed and determinable quantities of crude oil or natural gas in the future.

Fuel purchase commitment – The Company has entered into a forward purchase contract with a third party to purchase specified quantities of diesel fuel at specified prices each month through June 2016 for use in drilling operations. Over the remaining contract term, the Company has committed to purchase approximately 11 million gallons of diesel fuel at varying prices depending on the grade of diesel fuel purchased and the timing and location of delivery. The contract satisfies a significant portion of the Company's anticipated diesel fuel needs and provides for physical delivery to desired locations. Future commitments under the arrangement as of December 31, 2015 total approximately $31 million, all of which will be incurred in 2016.
Litigation –In November 2010, an allegeda putative class action was filed in the District Court of Blaine County, Oklahoma by Billy J. Strack and Daniela A. Renner as trustees of certain named trusts and on behalf of other similarly situated parties against the Company allegingCompany. The Petition alleged the Company improperly deducted post-production costs from royalties paid to plaintiffs and other royalty interest owners as categorized in the petition from crude oil and natural gas wells located in Oklahoma. The plaintiffs have alleged a number of

claims, including breach of contract, fraud, breach of fiduciary duty, unjust enrichment, and other claims and seek recovery of compensatory damages, interest, punitive damages and attorney fees on behalf of the allegedproposed class. On November 3, 2014, plaintiffs filed an Amended Petition that did not add any substantive claims, but sought a “hybrid class action” in which they sought certification of certain claims for injunctive relief, reserving the right to seek a further class certification on money damages in the future. Plaintiffs filed an Amended Motion for Class Certification on January 9, 2015, that modified the proposed class to royalty owners in Oklahoma production from July 1, 1993, to the present (instead of 1980 to the present) and sought certification of over 45 separate “issues” for injunctive or declaratory relief, again, reserving the right to seek a further class certification of money damages in the future. The Company has responded to the petition, deniedits amendment, and the motions for class certification denying the allegations and raisedraising a number of affirmative defenses. Discoverydefenses and legal arguments to each of the claims and filings. Certain discovery was undertaken and the “hybrid” motion was briefed by plaintiffs and the Company. A hearing on the “hybrid” class certification was held on June 1st and 2nd, 2015. On June 11, 2015, the trial court certified a “hybrid” class as requested by plaintiffs. The Company has appealed the trial court’s class certification order, which will be reviewed de novo by the appellate court. The appeal briefing is ongoingcomplete and information and documents continue to be exchanged.ready for determination by the court. An unsuccessful mediation was conducted on December 7, 2015. The Company is not currently able to estimate a reasonably possible loss or range of loss or what impact, if any, the action will have on its financial condition, results of operations or cash flows due to the preliminary status of the

The class hasAlthough not been certified. Plaintiffscurrently at issue in the “hybrid” certification, plaintiffs have indicated that if the class is certified they may seek damagesalleged underpayments in excess of $145$200 million that they may claim as damages, which may increase with the passage of time, a majority of which would be comprised of interest. The Company disputes plaintiffs’ claims, disputes that the case meets the requirements for a class action and is vigorously defending the case.

The Company will continue to assert its defenses to the case as certified as well as any future attempt to certify a money damages class.

The Company is involved in various other legal proceedings such asincluding, but not limited to, commercial disputes, claims from royalty and surface owners, property damage claims, personal injury claims, disputes with tax authorities and similarother matters. While the outcome of these legal matters cannot be predicted with certainty, the Company does not expect them to have a material effect on its financial condition, results of operations or cash flows. As of December 31, 20122015 and 2011,2014, the Company hashad recorded a liability on the consolidated balance sheets under the caption “Other noncurrent liabilities” of $2.4$6.1 million and $2.6$2.9 million, respectively, for various matters, none of which are believed to be individually significant.

Environmental Riskrisk Due to the nature of the crude oil and natural gas business, the Company is exposed to possible environmental risks. The Company is not aware of any material environmental issues or claims.

Dispositions

In December 2012,2015, the Company sold its producing crude oil and natural gascertain non-strategic properties and supporting assets in its East regionvarious areas to a third partyparties for $126.4 million, subjectproceeds totaling $34.0 million. The proceeds primarily related to customary post-closing adjustments. In connection with the transaction, the Company recognized a pre-tax gainassignment of $68.0 million, which included the effect of removing $8.3 million of asset retirement obligations for the disposed properties previously recognized by the Company that were assumed by the buyer. The transaction excluded a portion of the Company’scertain non-producing leasehold acreage in the East region, which is being retained by the Company for future exploration and development opportunities. The transaction also allowed for the Company to retain an overriding royalty interest in certain of the disposed properties as well as rights to drill in potential unproven deeper formations that may exist below the disposed properties. The producing properties included in the disposition comprised 399 MBoe, or 1%, of the Company’s total crude oil and natural gas production for 2012. Crude oil and natural gas revenues for the disposed properties amounted to $35 million for 2012, representing 1% of the Company’s total crude oil and natural gas revenues for the year. The disposed properties had represented approximately 1% of the Company’s total proved reserves prior to disposition.

In June 2012, the Company assigned certain non-strategic leaseholds and producing properties located in Oklahoma to a third party for $15.9$25.9 million andin May 2015. The Company recognized a pre-tax gain on the transaction of $15.9$20.5 million. The assigned properties represented an immaterial portion of the Company’s leasehold acreage.

During the year ended December 31, 2014, the Company sold certain non-strategic properties in various areas to third parties for proceeds totaling $129.4 million. The proceeds primarily related to dispositions of properties in the Niobrara play in Colorado and Wyoming in March 2014 for proceeds totaling $30.3 million which included the effect of removing $0.6and $85.8 million of asset retirement obligations forproceeds received in conjunction with the disposeddisposition of a portion of the Company's Northwest Cana properties previously recognized by the Company that were assumed by the buyer.in Oklahoma in September 2014. The disposed properties represented an immaterial portion of the Company’s total proved reserves, and production.

In February 2012, the Company assigned certain non-strategic leaseholds and producing properties located in Wyoming to a third party for $84.4 million. In connection with the transaction, the Company recognized a pre-tax gain of $50.1 million, which included the effect of removing $11.1 million of asset retirement obligations for the disposed properties previously recognized by the Company that were assumed by the buyer. The disposed properties had represented 3.2 MMBoe, or 1%, of the Company’s total proved reserves at December 31, 2011 and 259 MBoe, or 1%, of its 2011 total crude oil and natural gas production.

During 2011, the Company assigned certain non-strategic properties in Michigan, North Dakota, and Montana to third parties for total proceeds of $30.2 million. In connection with the transactions, the Company recognized pre-tax gains totaling $21.4 million.

Note 14. Property Transaction with Related Party

On March 27, 2012, the Company entered into a Reorganization and Purchase and Sale Agreement (the “Agreement”) with Wheatland Oil Inc. (“Wheatland”) and the shareholders of Wheatland. Wheatland is owned 75% by the Revocable Inter Vivos Trust of Harold G. Hamm, a trust of which Harold G. Hamm, the Company’s Chief Executive Officer, Chairman of the Board and principal shareholder is the trustee and sole beneficiary, and 25% by the Company’s Vice Chairman of Strategic Growth Initiatives, Jeffrey B. Hume. The Agreement provided for the acquisition by the Company, through the issuance of shares of the Company’s common stock, of

Continental Resources, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

all of Wheatland’s right, title and interest in and to certain crude oil and natural gas properties and related assets, in which the Company also owned an interest, in the states of Mississippi, Montana, North Dakota and Oklahoma and the assumption of certain liabilities related thereto.

A special meeting of the Company’s shareholders was held on August 10, 2012 for the purpose of voting on whether to approve the issuance of shares of the Company’s common stock pursuant to the Agreement as required by Oklahoma state law, the requirements of the New York Stock Exchange Listed Company Manual and the terms of the Agreement. The proposal to issue shares of the Company’s common stock pursuant to the Agreement received the requisite affirmative shareholder votes at the August 10, 2012 special meeting to satisfy the necessary approval requirements. As a result, the Wheatland transaction was consummated and closed on August 13, 2012, with an effective date of January 1, 2012. At closing, after considering customary purchase price adjustments, the Company issued an aggregate of approximately 3.9 million shares of its common stock, par value $0.01 per share, to the shareholders of Wheatland in accordance with the terms of the Agreement. The fair value of the consideration transferred by the Company at closing was approximately $279 million.

For accounting purposes, the acquisition represented a transaction between entities under common control as Mr. Hamm is the controlling shareholder of both the Company and Wheatland. Accordingly, the Company recorded the assets acquired and liabilities assumed at Wheatland’s carrying amount. The net book basis of Wheatland’s assets was approximately $82 million, primarily representing $177 million for acquired crude oil and natural gas properties partially offset by $38 million of joint interest obligations assumed, $0.6 million of asset retirement obligations assumed and $57 million of deferred income tax liabilities recognized. All purchase price adjustments arising after the closing date as allowed for under the Agreement, which amounted to $0.5 million being owed to the Company by Wheatland, have been agreed upon by the parties and are reflected in the Company’s consolidated financial statements at December 31, 2012.

The Company’s consolidated financial statements at December 31, 2012 include the results of operations and cash flows for the acquired properties subsequent to the closing date. For the year ended December 31, 2012, the acquired Wheatland properties comprised approximately 484 MBoe of the Company’s crude oil and natural gas production, and approximately $38 million of its crude oil and natural gas revenues.

Note 15. Relocation of Corporate Headquarters

In March 2011, the Company announced plans to relocate its corporate headquarters from Enid, Oklahoma to Oklahoma City, Oklahoma. The Company’s relocation efforts were completed during 2012. For the years ended December 31, 2012 and 2011, the Company recognized $7.8 million and $3.2 million, respectively, of costs associated with its relocation efforts. These costs are included in the caption “General and administrative expenses” in the consolidated statements of income.

Under the successful efforts method of accounting, the costs of drilling an exploratory well are capitalized pending determination of whether proved reserves can be attributed to the discovery. When initial drilling operations are complete, management determinesattempts to determine whether the well has discovered crude oil and natural gas reserves and, if so, whether those reserves can be classified as proved reserves. Often, the determination of whether proved reserves can be recorded under SEC guidelines cannot be made when drilling is completed. In those situations where management believes that economically producible hydrocarbons have not been discovered, the exploratory drilling costs are reflected on the consolidated statements of comprehensive income (loss) as dry hole costs, a component of “Exploration expenses”. Where sufficient hydrocarbons have been discovered to justify further exploration or appraisal activities, exploratory drilling costs are deferred under the caption “Net property and equipment” on the consolidated balance sheets pending the outcome of those activities.

On a quarterly basis, operating and financial management review the status of all deferred exploratory drilling costs in light of ongoing exploration activities—in particular, whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts. If management determines that future appraisal drilling or development activities are not likely to occur, any associated exploratory well costs are expensed in that period of determination.

Note 17.16. Supplemental Crude Oil and Natural Gas Information (Unaudited)

The table below shows estimates of proved reserves prepared by the Company’s internal technical staff and independent external reserve engineers in accordance with SEC definitions. Ryder Scott Company, L.P. ("Ryder Scott") prepared reserve estimates for properties comprising approximately 99%, 96%99%, and 94%99% of the Company’s discounted future net cash flows (PV-10) as of December 31, 2012, 2011,2015, 2014, and 2010,2013, respectively. Properties comprising 99% of proved crude oil reserves and 96%97% of proved natural gas reserves were evaluated by Ryder Scott as of December 31, 2012.2015. Remaining reserve estimates were prepared by the Company’s internal technical staff. All proved reserves stated herein are located in the United States.

No proved reserves have been recorded for the Company's Canadian operations at December 31, 2015.

Proved reserves are estimated quantities of crude oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be economically producible in future periods from known reservoirs under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates renewal is reasonably certain. There are numerous uncertainties inherent in estimating quantities of proved crude oil and natural gas reserves. Crude oil and natural gas reserve engineering is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be precisely measured, and estimates of engineers other than the Company’s might differ materially from the estimates set forth herein. The accuracy of any reserve estimate is a function of the

Accordingly, reserve estimates are often differentmay differ significantly from the quantities of crude oil and natural gas ultimately recovered.

Reserves at December 31, 2012, 20112015, 2014 and 20102013 were computed using the 12-month unweighted average of the first-day-of-the-month commodity prices as required by SEC rules.

Revisions. Revisions represent changes in previous reserve estimates, either upward or downward, resulting from new information normally obtained from development drilling and production history or resulting from a change in economic factors, such as commodity prices, operating costs or development costs. Revisions for

Downward revisions to proved reserves in 2013 primarily represented the year ended December 31, 2010 were dueremoval of PUD reserves resulting from a decision in 2013 to better than anticipated production performancefocus the Company's drilling program on certain areas of the Bakken and higher average commodity prices throughout 2010 as comparedSCOOP plays with more attractive rates of return and multi-well pad drilling capabilities, while building on success in the Company's development of the Lower Three Forks reservoirs in the Bakken.
Downward revisions to 2009. Revisionsproved reserves in 2014 resulted from the Company refining its drilling program and reducing its planned rig count in response to the significant decrease in crude oil reserves forprices in the year ended December 31, 2011 were due to better than anticipated production performance and higher average commodity prices throughout 2011 as compared to 2010. Revisions to natural gas reserves for bothlatter part of the years ended December 31, 2011 and 2012 were primarily due2014, which contributed to the removal of PUD reserves no longer scheduled to be developed within five years from the date in which they were first booked.
Downward revisions to proved undeveloped reserves in 2015 resulted primarily from the significant decrease in commodity prices in 2015. The 12-month average price for crude oil decreased 47% from $94.99 per Bbl for 2014 to $50.28 per Bbl for 2015, while the 12-month average price for natural gas decreased 41% from $4.35 per MMBtu for 2014 to $2.58 per MMBtu for 2015. These decreases shortened the economic lives of certain producing properties and caused certain exploration and development projects to become uneconomic which had an adverse impact on the Company's proved reserve estimates, resulting in downward revisions of 185 MMBo and 391 Bcf (totaling 251 MMBoe) in 2015.
In response to the continued decrease in commodity prices throughout 2015, the Company has further refined its drilling program and reduced its planned rig count to concentrate its efforts in core areas of North Dakota and Oklahoma that provide the best opportunities to improve recoveries and rates of return. The refinement of the Company's drilling program contributed to the removal of PUD reserves no longer scheduled to be developed within five years from management’s decisionthe date in which they were first booked. One element leading to deferthe removal is an increased emphasis on multi-well pad drilling in the Bakken, which resulted in the removal of PUDs in certain areas in favor of PUDs more likely to be developed with pad drilling where operating efficiencies may be realized. Further, in the SCOOP play the Company removed certain PUD locations originally planned to be developed with standard lateral drilling lengths in favor of PUDs to be developed with extended length laterals in similar

locations that provide opportunities for improved well productivity and economics. The combination of these and other factors resulted in the removal of 65 MMBo and 197 Bcf (totaling 98 MMBoe) of PUD reserves in 2015.
Additionally, changes in anticipated production performance on certain dryproperties resulted in 63 MMBo of downward revisions to crude oil proved reserves and 125 Bcf of upward revisions to natural gas propertiesproved reserves (netting to 42 MMBoe of downward revisions) in the Oklahoma Woodford play given the pricing environment for natural gas.

2015.

The downward revisions described above were partially offset by upward revisions in 2015 due to lower operating costs being realized in conjunction with depressed commodity prices and improvements in operating efficiencies as well as other factors.
Extensions, discoveries and other additions.These are additions to proved reserves resulting from (1) extension of the proved acreage of previously discovered reservoirs through additional drilling in periods subsequent to discovery and (2) discovery of new fields with proved reserves or of new reservoirs of proved reserves in old fields.

In 2012, significant progress continued to be madeSCOOP totaled 36 MMBo and 340 Bcf (totaling 93 MMBoe) for the year ended December 31, 2015. Additionally, 2015 extensions and discoveries were significantly impacted by successful drilling results in developingthe Northwest Cana/STACK area, resulting in proved reserve additions of 20 MMBo and expanding the Company’s North Dakota Bakken assets, both laterally and vertically, through strategic exploration, planning and technology.

Standardized measure of discounted future net cash flows relating to proved crude oil and natural gas reserves

The standardized measure of discounted future net cash flows presented in the following table was computed using the 12-month unweighted average of the first-day-of-the-month commodity prices, the costs in effect at December 31 of each year and a 10% discount factor. The Company cautions that actual future net cash flows may vary considerably from these estimates. Although the Company’s estimates of total proved reserves, development costs and production rates were based on the best available information, the development and production of the crude oil and natural gas reserves may not occur in the periods assumed. Actual prices realized, costs incurred and production quantities may vary significantly from those used. Therefore, the estimated future net cash flow computations should not be considered to represent the Company’s estimate of the expected revenues or the current value of existing proved reserves.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of December 31, 20122015 to ensure that information required to be disclosed in the reports it files and submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that information required to be disclosed under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control Over Financial Reporting


MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING


Our Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Under the supervision and with the participation of our Company’s management, including the Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework inInternal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Our internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of our consolidated financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on our evaluation under the framework inInternal Control—Integrated Framework (2013), the management of our Company concluded that our internal control over financial reporting was effective as of December 31, 2012.2015.

The effectiveness of our internal control over financial reporting as of December 31, 20122015 has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in their report that follows.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Board of Directors and Shareholders

Continental Resources, Inc.

We have audited the internal control over financial reporting of Continental Resources, Inc. (an Oklahoma corporation) and Subsidiariessubsidiaries (the “Company”) as of December 31, 2012,2015, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanyingManagement’s Report on Internal Control Overover Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012,2015, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended December 31, 2012,2015, and our report dated February 27, 201324, 2016 expressed an unqualified opinion on those financial statements.

Based on that evaluation, there were no changes in our internal control over financial reporting or in other factors during the fourth quarter of 2012 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.
