Company Overview
Pioneer Energy Services Corp. provides land-based drilling services and production services to a diverse group of independent and large oil and gas exploration and production companies in the United States and internationally in Colombia. We also provide two of our services (coiled tubing and wireline services) offshore in the Gulf of Mexico. Drilling services and production services are fundamental to establishing and maintaining the flow of oil and natural gas throughout the productive life of a well and enable us to meet multiple needs of our clients.well.
Drilling Services Segment—Services— From 1999 to 2011, we significantly expanded our fleet through acquisitions and the construction of new drilling rigs. As our industry changed with the evolution of shale drilling, we began a transformation process in 2011 by selectively disposing of our older, less capable rigs, while we continued to invest in our rig building program to construct more technologically advanced, pad-optimal rigs to meet the changing needs of our clients.
As of December 31, 2016, ourOur current drilling rig fleet is 100% pad-capable. We offerpad-capable and offers the latest advancements in pad drilling with our fleet ofdrilling. We have 16 AC rigs in the US and eight SCR rigs in Colombia, all of which have 1,500 horsepower or greater drawworks. The removal of older, less capable rigs from our fleet and the recent investments in the construction of new drilling rigs has transformed our fleet into a highly capable, pad optimal fleet focused on the horizontal drilling market. We believe this positions us to compete well, grow our presence in the significant shale basins in the US, and improve profitability as the recovery of our industry continues.profitability.
In addition to our drilling rigs, weWe provide a comprehensive service offering which includes the drilling rig, crews, supplies and most of the ancillary equipment needed to operate our drilling rigs. We obtainrigs which are deployed through our contracts for drilling oil and natural gas wells either through competitive bidding or through direct negotiations with existing or potential clients. Our drilling contracts generally provide for compensation on a daywork basis, and sometimes on a turnkey basis. Contract terms generally depend on the complexity and risk of operations, the on-site drilling conditions, the type of equipment used, and the anticipated duration of the work to be performed. The drilling rigsdivision offices in our fleet are currently assigned to the following divisions:regions:

Production Services Segment—Services— In 2008, we acquired two production services companies which significantly expanded our service offerings to include well servicing and wireline services. Atservices, and at the end of 2011, we acquired a coiled tubing services business to further expand our production services offerings. Since the acquisitions of these businesses, we continued to invest in their organic growth and significantly expanded all our production services fleets. However,Although we temporarily suspended organic growth of our production services fleets during the recent downturn, andwe continue to selectively update our fleets.
Our Production Services Segment providesToday, our production services business segments provide a range of well, wireline and coiled tubing services to a diverse group of exploration and production companies, with our operations concentrated in the major United Statesdomestic onshore oil and gas producing regions in the Gulf Coast, Mid-Continent and Rocky Mountain states and in the Gulf Coast, both onshore and offshore.states. The primary production services we offer are the following:
Well Servicing. Servicing. A range of services are required in order to establish production in newly-drilled wells and to maintain production over the useful lives of active wells. We use our well servicing rig fleet to provide these necessary services, including the completion of newly-drilled wells, maintenance and workover of active wells, and plugging and abandonment of wells at the end of their useful lives. As of December 31, 2016, 2018,we have a fleet of 114113 rigs with 550 horsepower and 1112 rigs with 600 horsepower with operations in 10 locations, mostly in the Gulf Coast states, as well as in ArkansasNorth Dakota and North Dakota.Colorado.

Wireline Services. Services. Oil and gas exploration and production companies require wireline services to better understand the reservoirs they are drilling or producing, and use logging services to accurately characterize reservoir rocks and fluids. To complete a cased-hole well, the production casing must be perforated to establish a flow path between the reservoir and the wellbore. We use our fleet of wireline units to provide these important logging and perforating services in addition to a range of other mechanical services that are needed in order to place equipment in or retrieve equipment or debris from the wellbore, install bridge plugs and control pressure. As of December 31, 2016,2018, we have a fleet of 114105 wireline units, in 17which are deployed through 13 operating locations in the Gulf Coast, Mid-Continent and Rocky Mountain states.

Coiled Tubing Services. Coiled tubing is also ananother important element of the well servicing industry that allows operators to continue production during service operations on a well under pressure without shutting in the well, thereby reducing the risk of formation damage. Coiled tubing services involve the use of a continuous flexible metal pipe which is spooled on a large reel forand inserted into the wellbore to perform a variety of oil and natural gas well applications, such as wellbore clean-outs, nitrogen jet lifts, through-tubing fishing, formation stimulation utilizing acid, chemical treatments and fracturing. Coiled tubing is also used for a number of horizontal well applications, such as milling temporary plugs between frac stages. As of December 31, 2016, our coiled tubing business consists2018, we have a current fleet of 12 onshore and five offshorenine coiled tubing units, the majority of which areoffer larger diameter coil (larger than two inches), deployed through threetwo operating locations that provide services in Texas, Wyoming and Louisiana.surrounding areas.

Industry Overview
Demand for oilfield services offered by our industry is a function of our clients’ willingness to make operating expenditures and capital expenditures to explore for, develop and produce hydrocarbons, which is primarily driven by current and expected oil and natural gas prices.
Our business is influenced substantially by both operating and capital expenditures by exploration and production companies. Exploration and productioncompanies’ spending that is generally categorized as either a capital expenditure or an operating expenditure.
Capital expenditures by oil and gas exploration and production companies tend to be relatively sensitive to volatility in oil or natural gas prices because project decisions are tied to a return on investment spanning a number of months or years. As such, capital expenditure economics often require the use of commodity price forecasts which may prove inaccurate over the amount of time necessary to plan and execute a capital expenditure project (such as a drilling program for a number of wells in a certain area). When commodity prices are depressed for longer periods of time, capital expenditure projects are routinely deferred until prices are forecasted to return to an acceptable level.
In contrast, both mandatory and discretionary operating expenditures are more stable than capital expenditures for exploration as these expenditures are less sensitive to commodity price volatility. Mandatory operating expenditure projects involve activities that cannot be avoided in the short term, such as regulatory compliance, safety, contractual obligations and certain projects to maintain the well and related infrastructure in operating condition. Discretionary operating expenditure projects may not be critical to the short-term viability of a lease or field and are generally evaluated according to a simple short-term payout criterion that is less dependent on commodity price forecasts.

Capital expenditures by exploration and production companies for the drilling and completion of exploratory wells or newand development wells in proven areas are more directly influenced by current and expected oil and natural gas prices and generally reflect the volatility of commodity prices. In contrast, operating expenditures by exploration and production companies for the maintenance of existing wells, for which a range of production services are required in order to maintain production, are relatively more stable and predictable.
Drilling and production services have historically trended similarly in response to fluctuations in commodity prices. However, because exploration and production companies often adjust their budgets for exploratoryexploration and development drilling first in response to a shiftchange in commodity prices, the demand for drilling services is generally impacted first and to a greater extent than the demand for production services which is more dependent on ongoing expenditures that are necessary to maintain production. Additionally, within the range of production services businesses, those that derive more revenue from production related activity, as opposed to completion of a new well,wells, tend to be less affected by fluctuations in commodity prices and temporary reductions in industry activity.
However, in a severe downturn that is prolonged, both operating and capital expenditures are significantly reduced, and the demand for all our service offerings is significantly impacted. After a prolonged downturn, among the production services, the demand for completion-oriented services generally improves first, as exploration and production companies begin to

complete wells that were previously drilled but not completed during the downturn, and to complete newly drilled wells as the demand for drilling services improves during recovery.
From time to time, temporary regional slowdowns or constraints occur in our industry due to a variety of factors, including, among others, infrastructure or takeaway capacity limitations, labor shortages, increased regulatory or environmental pressures, or an influx of competitors in a particular region. Any of these factors can influence the profitability of operations in the affected region. However, term contract coverage for our drilling services business and the mobility of all our equipment between regions limits our exposure to the impact of regional constraints and fluctuations in demand.
Our industry experienced a severe down cycle from late 2014 through 2016, during which WTI oil prices dipped below $30 per barrel in early 2016. A modest recovery in commodity prices began in the latter half of 2016 with WTI oil prices steadily increasing from just under $50 per barrel at the end of June 2016 to approximately $60 per barrel at the end of 2017. In 2018, WTI oil prices continued to increase to a high of $75 per barrel in October, but then decreased to $45 per barrel at the end of 2018, and averaged approximately $50 per barrel during January 2019. The trends in spot prices of WTI crude oil and Henry Hub natural gas, and the resulting trends in domestic land rig counts (per Baker Hughes) and domestic well servicing rig counts (per Guiberson/Association of Energy Service Companies) over the last three years are illustrated in the graphs below.
As shown in the charts above, the trends in industry rig counts are influenced primarily by fluctuations in oil prices, which affect the levels of capital and operating expenditures made by our clients.a3yrspotpricesandrigcountv2.jpg
Colombian oil prices have historically trended in line with West Texas Intermediate (WTI) oil prices. Demand for drilling and production services in Colombia is largely dependent upon its national oil company’s long-term exploration and production programs, and to a lesser extent, additional activity from other producers in the region.
Technological advancements and trends in our industry also affect the demand for certain types of equipment, and can affect the overall demand for equipment inthe services our industry. For several years, prior to late 2014, higher oil prices drove industry equipment utilizationprovides. Enhanced directional and revenue rates up, particularly in oil-producing regions and certain shale regions. However, advancements in technology improved the efficiency ofhorizontal drilling rigs and overall demand remained steady, while the demand for certain drilling rigs decreased, particularly in vertical well markets. The decline was a result of higher demand for drilling rigs that are able to drill horizontally and the increased use of “pad drilling” which enables a series of horizontal wells to be drilled in succession by walking or skidding a drilling rig at a single pad-site location, thereby improving the productivity oftechniques have allowed exploration and production activities.operators to drill increasingly longer lateral wellbores which enable higher hydrocarbon production per well, and reduce the overall number of wells needed to achieve the desired production. This trend then coupled with the downturn, resulted in significantly reducedtoward longer lateral wellbores also increases demand for the more specialized equipment, such as high-spec drilling rigs, that do not have the ability to walk or skidhigher horsepower well servicing rigs equipped with taller masts, larger diameter coiled tubing units, and other higher power ancillary equipment, which is needed in order to drill, horizontal wells.complete and provide services to the full length of the wellbore. Our domestic drilling and production services fleets are highly capable and designed for operation in today’s long lateral, pad-oriented environment.

Our well servicing fleet is 100% tall-masted, 550 to 600 horsepower rigs, and 75%making them well suited for operating in today’s long lateral environment. Additionally, the majority of our onshore coiled tubing units are shale-ready units which offer larger diameter coil. We also currentlycoil, and we have commitmentsadded capacity to purchase four newour wireline fleet focused on higher-spec units designed for completion work in unconventional areas, units which offer greaseless electric wireline used to reach further depths in longer laterals and 20 new-model well servicing rigs, for which we will tradeEcoQuietSM units designed to reduce noise when operating in 20 of our older well servicing rigs.proximity to urban areas. We believe that our modern and well maintained fleet allowswell-maintained fleets allow us to realize higher utilization and pricing because we are able to offer our clients technologically advanced equipment that allows them to operate in the most challenging markets, with less downtime and greater efficiency.
One of theA Leading ProvidersProvider in the Prominent Domestic Regions.Shale Regions. Our drilling and production services fleets operate in many of the most attractive producing regions in the United States, including the Utica, Marcellus, Eagle Ford, Niobrara, multiple shales in the Permian Basin, SCOOP/STACK and the Bakken. OurWe believe our drilling rigs are currently located in four divisions throughout the United States and Colombia. We believe the varied capabilities of our drilling rigs make them particularly well suited to these areas where the optimal rig configuration is dictated by local geology and market conditions. In addition,conditions, and we have focused the expansion of our production services fleets has been focused on thoseto these regions with the most opportunity for growth. All our fleet equipment is mobile between domestic regions, diversifying our geographic exposure and limiting the impact of any regional slowdown.
Provide Services Throughout the Well Life Cycle. By offering our clients both drilling and production services, we capture revenue throughout the life cycle of a well and diversify our business. Our Drilling Services Segmentdrilling services business performs work prior to initial production, and our Production Services Segmentproduction services business provides services such as logging, completion, perforation, workover and maintenance throughout the productive life of a well. We also provide certain end-of-well-life activities such as plugging and abandonment. Drilling and production services activity have historically exhibited different degrees of demand fluctuation, and we believe the diversity of our services reduces our exposure to decreases in demand for any single service activity. Further, the diversity of our service offerings enables us to cross-sell our services, which has allowed us to generate more business from existing clients and increase our profits as we expand our services within existing markets.
Industry-Leading Safety Record. Our safety program called “LiveSafe” focuses on creating an environment where everyone is committed to and recognizes the possibility of always working without incident or injury.

Strategy
Our strategy has beenis to becomebe a premier land drilling and production services company through steady and disciplined growth, which we executed through the acquisition and building of our high quality drilling rig fleet and production services businesses. In 2011, we shifted our approach to accommodate changes in the industry, which resulted in a period of combined growth and rejuvenation through the disposition of assets which use older technology. Today, we provide drilling and production services in many of the most attractive drillinghydrocarbon producing markets throughout the United States, and provide drilling services in Colombia.
WithOur long-term strategy as a premier land drilling and production services company is to further leverage our relationships with existing clients, within and across business lines, expand our client base in the declineareas where we currently operate, grow our geographic diversification through selective expansion, and continue to identify and develop opportunities to enhance our service offerings. The key elements of this long-term strategy are focused on our:
Performance in oilour Core Businesses. We maintain a continual focus on our relationships with our clients and vendors, and our commitment to safety and service quality goals. In 2018, our domestic drilling business achieved record safety results and based on currently available industry data, was ranked first among the top 10 most active contractors. In addition, our well servicing segment achieved its lowest total recordable incident rate in its history. As a result, for the second year in a row, our consolidated total recordable incident rate was below 1.0 and we lowered our lost time incident rates for the fifth consecutive year, achieving the lowest in our company’s history. Our excellent safety record and reputation are critical to winning new business and expanding our relationships with existing clients.
Investments in Our Business. We have historically invested in the growth and technological advancement of our business by engaging in select rig building opportunities and acquisitions, strategically upgrading our existing assets and disposing of assets which use older technology. From 2011 to 2016, we constructed 15 walking AC drilling rigs and removed all non-AC drilling rigs from our domestic fleet. Our current drilling rig fleet is 100% pad-capable and offers the latest advancements in pad drilling. We have 16 AC rigs in the US and eight SCR rigs in Colombia, all of which have 1,500 horsepower or greater drawworks, and we are currently completing construction of a 17th AC drilling rig with a three-year term contract, which we expect to deploy in early 2019 to the Permian Basin. The removal of older, less capable rigs from our fleet and investments in the construction of new drilling rigs has transformed our fleet into a highly capable, pad optimal fleet focused on the horizontal drilling market. Since the beginning of 2010, we have added significant capacity to our production services offerings through the addition of 42 wireline units, 51 well servicing rigs and 9 coiled tubing units, all of which are net of various dispositions and replacements which were made to continuously rejuvenate our fleet with new equipment using the latest advancements in technologies. We believe this positions us to compete well, grow our presence in the significant shale basins in the US, and improve profitability.
A Leading Provider in Domestic Shale Regions. The investments we’ve made in our business have been focused on increasing our presence in regions where demand benefits from shale development. Shale plays are increasingly important to domestic hydrocarbon production, and not all rigs are capable of successfully working in these unconventional producing regions. Our domestic drilling and production services fleets are highly capable and designed for operation in today’s long lateral, pad-oriented environment. We are currently operating in the Utica, Marcellus, Eagle Ford, Niobrara, multiple shales in the Permian Basin, SCOOP/STACK and Bakken. We continue to allocate our resources to the markets with the best opportunities for increased activity, and to upgrade / reactivate previously idle units in areas with increasing demand.
Though we have remained committed to our long-term strategy, in recent years, our industry has suffered a severe downturn which began in late 2014 and persisted through 2016, followed by a slow but moderate recovery in 2017 and 2018, but with commodity prices that began in 2014have since languished. During this time, our recent and the resulting reductions in our utilization and revenue rates, our near-termnear term efforts have been focused on:on the following initiatives:
Cost Reductions.Adapting our Business.

Since the beginning of 2010, we have added significant capacity to our production services offerings through the addition of 51 wireline units, 51 well servicing rigs and 17 coiled tubing units. From 2011 to 2015, we constructed 15 walking AC drilling rigs, five of which were completed in 2015. During 2015 and 2016, we removed all 31 of our mechanical and lower horsepower electric drilling rigs from our fleet, which were the most negatively impacted by the industry downturn, as well as all 12 domestic SCR rigs in our fleet. We achieved this by selling a total of 35 drilling rigs, retiring two, and placing the remaining six as held for sale.
As of December 31, 2016, our drilling rig fleet is 100% pad-capable. We offer the latest advancements in pad drilling with our fleet of 16 AC rigs in the US and eight SCR rigs in Colombia, all of which have 1,500 horsepower or greater drawworks. The removal of older, less capable rigs from our fleet and the recent investments in the construction of new drilling rigs has transformed our fleet into a highly capable, pad optimal fleet focused on the horizontal drilling market. We believe this positions us to compete well, grow our presence in the significant shale basins in the US, and improve profitability as the recovery of our industry continues.
Competitive Position in the Prominent Domestic Markets. Shale plays and non-shale oil or liquid rich environments are increasingly important to domestic hydrocarbon production, and not all drilling rigs are capable of successfully drilling in these unconventional opportunities. Our pad-optimal domestic fleet was designed for operation in the Marcellus, Eagle Ford, Permian Basin and the Bakken. Additionally, the added capacity in our production services fleets was focused on increasing our presence in those regions where demand benefits from shale development.
Exposure to Oil and Liquids Rich Natural Gas Drilling Activity. We believe that our flexible drilling and production services fleets allow us to pursue varied opportunities, enabling us to focus on a favorable mix of natural gas, oil and liquids rich natural gas activity. When natural gas prices fell to low levels, we increased our exposure to oil-related activities by redeploying certain of our assets into predominately oil-producing regions. As our industry continues to recover from the downturn that began in late 2014, we believe our fleets are highly capable and well positioned for deployment to whichever markets offer the most opportunity.
Overview of Our Segments and Services
Our business is comprised of two business lines Drilling Services and Production Services. We report our Drilling Services business as two reportable segments: (i) Domestic Drilling and (ii) International Drilling. We report our Production Services business as three reportable segments: (i) Well Servicing, (ii) Wireline Services, and (iii) Coiled Tubing Services. Financial information about our operating segments is included in Note 11, Segment Information, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Drilling Services
A land drilling rig consists of power generation system(s), a hoisting system, a rotating system, pumps and related equipment to circulate and clean drilling fluid, blowout preventers, and other related equipment. Generally, our land drilling rigs operate with crews of five to six persons, and 100% of our drilling rigs have the ability to drill multiple well bores from a single surface location as discussed in more detail below.
There are numerous factors that differentiate land drilling rigs, such as the type of power used, drilling depth capabilities or drawworks horsepower, mud pump pressure rating, and the ability to drill multiple well bores from a single surface location or pad. 
Regarding the type of power used, mechanical rigs are generally less expensive than their electric counterparts. Mechanical rigs use torque converters, clutches, chains, belts, and transmissions to couple engines directly to various types of equipment. Mechanical rigs are considered less efficient and less precise as the main drives are more challenging to control.than SCR rigs and AC rigs, which are considered electric rigs. Bothrigs that generate electrical power through one or more engine generator sets. SCR rigs utilize direct current to supply and control DC motors coupled to the various drilling equipment, while AC rigs utilize alternating current and AC motors. Both types of electric rigs are considered safer, more reliable, and more efficient than mechanical rigs. AC rigs are considered to be more energy efficient and provide more precise control of equipment than their SCR counterparts, which enhances rig safety and reduces drilling time.

Technological advancements and trends in our industry affect the demand for certain types of equipment. Every drilling rig in our fleet is equipped with at least 1,500 horsepower drawworks, a top drive, an iron roughneck, an automatic catwalk, and a walking or skidding system. This equipment, which is described in more detail below, provides our clients with drilling rigs that have more varied capabilities for drilling in unconventional plays and improves our efficiency and safety.
In horizontal well drilling, operators can utilize top drives to reach formations that may not be accessible with conventional rotary drilling. Top drives provide maximum torque and rotational control improved wellwhich increases the degree of control afforded the operator, and better hole conditioning.reduces the difficulties encountered while drilling horizontal wells. An iron roughneck is a remotely operated pipe handlingpipe-handling feature on the rig floor, which is used to help reduce the occurrence of repetitive motion injuries and decrease drill pipe tripping time. An automated catwalk is a drill pipe handlingpipe-handling feature used to raise drill pipe, drill collars, casing, and other necessary items to the drilling rig floor. Its function has significant safety advantages and can reduce the overall time required to complete the well.
In recent years, oilOil and gas exploration and production companies have increased thetypically prefer to use of “pad drilling” wherebywhich allows a series of horizontal wells areto be drilled in succession by walking or skidding a drilling rig at a single pad-site location. Walking systems increase efficiency by allowing multiple wells to be drilled on the same pad site and permitting the drilling rig to move between wells while drill pipe remains in the derrick and ancillary systems such as engines and mud tanks remain stationary, thus reducing move times and costs. Our omnidirectional walking systems enable the drilling rig to move forward, backward, and side to side which affords the operator additional flexibility.
The following table sets forth historical information regarding utilization for our drilling rig fleet:

The utilization of our AC fleet was 74% during both of the years ended December 31, 2016 and 2015.
As our industry changed with the evolution of shale drilling, we began a transformation process in 2011, by selectively disposing of our older, less capable rigs, while we continued to invest in our rig building program to construct more technologically advanced, pad-optimal rigs to meet the changing needs of our clients. From 2011 to 2015, we constructed 15 walking AC drilling rigs, five of which were completed in 2015. During 2015 and 2016, we removed all 31 of our mechanical and lower horsepower electric drilling rigs from our fleet, which were the most negatively impacted by the industry downturn, as well as all 12 domestic SCR rigs in our fleet. We achieved this by selling a total of 35 drilling rigs, retiring two, and placing the remaining six as held for sale. The removal of older, less capable rigs from our fleet and the recent investments in the construction of new drilling rigs has transformed our fleet into a highly capable, pad optimal fleet focused on the horizontal drilling market.
We believe that our drilling rigs and other related equipment are in good operating condition. Our employees perform periodic maintenance and minor repair work on our drilling rigs. We rely on various oilfield service companies for major repair work and overhaul of our drilling equipment when needed. We also engage in periodic improvement and upgrades of our drilling equipment. In the event of major breakdowns or mechanical problems, our rigs could be subject to significant idle time and a resulting loss of revenue if the necessary repair services are not immediately available.
In addition to our drilling rigs,Daywork contracts are comprehensive agreements under which we provide a comprehensive service offering, including the drilling crewsrig, crew, supplies and most of the ancillary equipment needednecessary to operate our drilling rigs.the rig. We obtain our contracts for drilling oil and natural gas wells either through competitive bidding or through direct negotiations with existing or potential clients. Our drilling contracts generally provide for compensation on a daywork basis, and sometimes on a turnkey basis. Contract terms generally depend on the complexity and risk of operations, the on-site drilling conditions, the type of equipment used, and the anticipated duration of the work to be performed. Spot market contracts generally provide for the drilling of a single well and typically permit the client to terminate on short notice. Drilling contracts for individual wells are usually completed in less than 30 days. We typically enter into longer-term drilling contracts for our newly constructed rigs and/or during periods of high rig demand.
Our business and the profitability of our operations depend on the level of drilling activity by oil and gas exploration and production companies operating in the geographic markets where we operate. The oil and gas exploration and production industry is a historically cyclical industry characterized by significant changes in the levels of exploration and development activities. During periods of reduced drilling activity or excess rig capacity, price competition tends

to increase and the profitability of daywork contracts tends to decrease, and in such a competitive price environment, we may be more inclined to enter into turnkey contracts that expose us to greater risk of loss but which offer higher potential contract profitability.
During the last three fiscal years, our drilling contracts have primarily been for daywork drilling. The following table presents, by type of contract, information about the total number of wells we completed for our clients during each of the last three fiscal years.

Production Services
Daywork Contracts. Under daywork drilling contracts, weOur production services business segments provide a drilling rigrange of well, wireline and required personnel to our client who supervises the drilling of the well. We are paid based on a negotiated fixed rate per day while the rig is used. Daywork drilling contracts specify the equipment to be used, the size of the hole and the depth of the well. Under a daywork drilling contract, the client bears a large portion of the out-of-pocket drilling costs and we generally bear no part of the usual risks associated with drilling, such as time delays and unanticipated costs.
Turnkey Contracts. Under a typical turnkey drilling contract, we agree to drill a well for our client to a specified depth and under specified conditions for a fixed price. We provide technical expertise and engineering services, as well as most of the equipment and drilling supplies required to drill the well. We often subcontract for related services, such as the provision of casing crews, cementing and well logging. Under typical turnkey drilling arrangements, we do not receive progress payments and are paid by our client only after we have performed the terms of the drilling contract in full.
For these reasons, the risk to us under a turnkey drilling contract is substantially greater than for a well drilled on a daywork basis because we must assume most of the risks associated with drilling operations that the operator generally assumes under a daywork contract, including the risks of blowout, loss of hole, stuck drill pipe, machinery breakdowns, abnormal drilling conditions and risks associated with subcontractors’ services, supplies, cost escalations and personnel. We believe that our experienced management team, our knowledge of geologic formations in our areas of operations, the condition of our drilling equipment and our experienced crews have previously enabled us to make reasonable cost estimates and complete contracts according to our drilling plan. While we do bear the risk of loss for cost overruns and other events that are not specifically provided for in our initial cost estimates, our pricing of turnkey contracts takes such risks into consideration, and we maintain insurance coverage against some, but not all, drilling hazards. During periods of reduced demand for drilling rigs, our overall profitability on turnkey contracts has historically exceeded our profitability on daywork contracts.
Production Services Segment
Our Production Services Segment provides a range ofcoiled tubing services to a diverse group of exploration and production companies, with our operations concentrated in the major United Statesdomestic onshore oil and gas producing regions in the Gulf Coast, Mid-Continent and Rocky Mountain states and in the Gulf Coast, both onshore and offshore. As of December 31, 2016, our production services fleets are as follows:

Well Servicingstates.. Our well servicing rig fleet provides a range of services, including the completion of newly-drilled wells, maintenance and workover of existing wells, and plugging and abandonment of wells at the end of their useful lives.

Newly drilled wells require completion services to prepare the well for production. Well servicing rigs are frequently used to complete newly drilled wells to minimize the use of higher cost drilling rigs in the completion process. The completion process may involve selectively perforating the well casing in the productive zones to allow oil or gas to flow into the well bore, stimulating and testing these zones and installing the production string and other downhole equipment. The completion process typically requires a few days to several weeks, depending on the nature and type of the completion, and generally requires additional auxiliary equipment. Accordingly, completion services require less well-to-well mobilization of equipment and can provide higher operating margins than regular maintenance work. The demand for completion services is directly related to drilling activity levels, which are sensitive to changes in oil and gas prices.
Regular maintenance is required throughout the life of a well to sustain optimal levels of oil and gas production. Common maintenance services include repairing inoperable pumping equipment in an oil well, and replacing defective tubing in a gas well.

well, cleaning a live well, and servicing mechanical issues. Our maintenance services involve relatively low-cost, short-duration jobs which are part of normal well operating costs. The need for maintenance does not directly depend on the level of drilling activity, although it is somewhat impacted by short-term fluctuations in oil and gas prices. Accordingly, maintenance services generally experience relatively stable demand; however, when oil or gas prices are too low to justify additional expenditures, operating companies may choose to temporarily shut in producing wells rather than incur additional maintenance costs.
In addition to periodic maintenance, producing oil and gas wells occasionally require major repairs or modifications called workovers, which are typically more complex and more time consuming than maintenance operations. Workover services include extensions of existing wells to drain new formations either through perforating the well casing to expose additional productive zones not previously produced, deepening well bores to new zones or the drilling of lateral well bores to improve reservoir drainage patterns. Our well servicing rigs are also used to convert former producing wells to injection wells through which water or carbon dioxide is then pumped into the formation for enhanced oil recovery operations. Workovers also include major subsurface repairs such as repair or replacement of well casing, recovery or replacement of tubing and removal of foreign objects from the well bore. These extensive workover operations are normally performed by a well servicing rig with additional specialized auxiliary equipment, which may include rotary drilling equipment, mud pumps, mud tanks and fishing tools, depending upon the particular type of workover operation. All of our well servicing rigs are designed to perform complex workover operations. A workover may require a few days to several weeks and generally requires additional auxiliary equipment. The demand for workover services is sensitive to oil and gas producers’ intermediate and long-term expectations for oil and gas prices.
Well servicing rigs are also used inAt the end of the well life cycle, a process ofis required to permanently closingclose oil and gas wells that are no longer capable of producing in economic quantities. Many well operators bid this work on a “turnkey” basis, requiring the service company to perform the entire job, including the sale or disposal of equipment salvaged from the well as part of the compensation received, and complying with state regulatory requirements. Plugging and abandonment work can provide favorable operating margins and is less sensitive to oil and gas pricing than drilling and workover activity since well operators must plug a well in accordance with state regulations when it is no longer productive.

We also perform plugging and abandonment work throughout our core areas of operation in conjunction with equipment provided by other service companies.
We typically bill clients forbelieve that our well servicing on an hourly basis during the period that the rig is actively working. We operate through 10 locations, mostly in the Gulf Coast states, as well as in Arkansas and North Dakota. We believe that our fleet is among the newest in the industry, consisting entirely of tall-masted rigs with at least 550 horsepower, capable of working at depths of over 20,000 feet. These specifications allow us to operate in areas with deeper well depths and perform jobs that rigs with lesser capabilities cannot. In late 2016,2017, we committed to tradetraded in 20 of our older 550 horsepower well servicing rigs for 20 new-model rigs, to be delivered in the first quarter of 2017, further improving the quality of our rig fleet, enhancing our ability to recruit crew talent and competitively positioning us for new service opportunities as the market improves. continues to improve.
Our well servicing utilization rates foroperations are deployed through 10 locations, mostly in the years ended December 31, 2016Gulf Coast states, as well as in North Dakota and 2015 were 41% and 65%, respectively, based on total fleet count.Colorado.
Wireline Services. Wireline trucks, like well servicing rigs, are utilized throughout the life of a well. Wireline trucks are often used in place of a well servicing rig when there is no requirement to remove tubulars from the well in order to make repairs.
Wireline services typically utilize a single truck equipped with a spool of wireline that is used to lower and raise a variety of specialized tools in and out of the wellbore.

Electric wireline contains a conduit that allows signals to be transmitted to or from tools located in the well. These tools can be used to measure pressures and temperatures as well

10



as the condition of the casing and the cement that holds the casing in place. In order for oil and gas exploration and production companies to better understand the reservoirs they are drilling or producing, they require logging services to accurately characterize reservoir rocks and fluids. We provide both open and cased-hole logging services.
Other applications for wireline tools include placing equipment in or retrieving equipment (or debris) from the wellbore, installing bridge plugs, perforating the casing in order to prepare the well for production, or cutting off pipe that is stuck in the well so that the free section can be recovered.
Our wireline operations are deployed through 1713 operating locations in Texas, Kansas, Colorado, Montana, North Dakota, Louisiana, Oklahomathe Gulf Coast, Mid-Continent and Wyoming. We are currently actively marketing approximately 65% of our wireline fleet.Rocky Mountain states.
Coiled Tubing ServicesServices.. Coiled tubing is also ananother important element of the well servicing industry that allows operators to continue production during service operations on a well under pressure without shutting in the well, thereby reducing the risk of formation damage. Coiled tubing services involve the use of a continuous flexible metal pipe which is spooled on a large reel forand inserted into the wellbore to perform a variety of oil and natural gas well applications, such as wellbore clean-outs, nitrogen jet lifts, through-tubing fishing, formation stimulation utilizing acid, chemical treatments and fracturing. Coiled tubing is also used for a number of horizontal well applications, such as milling temporary plugs between frac stages.
Our coiled tubing operations are deployed through threetwo operating locations that provide services in Texas, Wyoming and Louisiana. Our coiled tubing utilization rates for the years ended December 31, 2016 and 2015 were 22% and 27%, respectively, based on total fleet count.surrounding areas.
Seasonality
All our production services operations are impacted by seasonal factors. Our business can be negatively impacted during the winter months due to inclement weather, fewer daylight hours, and holidays. BecauseWhile our well servicing rigs, wireline units and coiled tubing units are mobile, during periods of heavy snow, ice or rain, we may not be able to move our equipment between locations.
Clients
We provide drilling and production services to numerous independent and large oil and gas exploration and production companies that are active in the geographic areas in which we operate.companies.

Competition
We encounter substantial competition from other drilling contractors and other oilfield service companies. Our primary market areas are highly fragmented and competitive. The fact that drilling and production services equipment are mobile and can be moved from one market to another in response to market conditions heightens the competition in the industry and may result in an oversupply of equipment in an area. Contract drilling companies and other oilfield service companies compete primarily on a regional basis, and the intensity of competition may vary significantly from

11



region to region at any particular time. If demand for drilling or production services improves in a region where we operate, our competitors might respond by moving in suitable rigs and production services equipment from other regions. An influx of equipment from

10



other regions could rapidly intensify competition, reduce profitability and make any improvement in demand for our services short-lived.
Most drilling services contracts and production services contracts are awarded on the basis of competitive bids, which also results in price competition. In addition to pricing and equipment availability, we believe the following factors are also important to our clients in determining which drilling services or production services provider to select:
the type, capability and condition of each of the competing drilling rigs, well servicing rigs, wireline units and coiled tubing units;
the mobility and efficiency of the equipment;
the quality of service and experience of the crews;
the reputation and safety record of the company providing the services;
the offering of integrated and/or ancillary services; and
the ability to provide drilling and production services equipment adaptable to, and personnel familiar with, new technologies and drilling and production techniques.
While we must be competitive in our pricing, our competitive strategy generally emphasizes the quality of our equipment, our safety record, our ability to offer ancillary services, the experience of our crews and the quality of service we provide to differentiate us from our competitors. This strategy is less effective when lower demand for drilling and production services intensifies price competition and makes it more difficult for us to compete on the basis of factors other than price. In all of the markets in which we compete, an oversupply of drilling rigs or production services equipment generally causes greater price competition and reduced profitability.
We believe that an important competitive factor in establishing and maintaining long-term client relationships is having an experienced, skilled and well-trained work force. In recent years, many of our larger clients have placed increased emphasis on the safety performance and quality of the crews, equipment and services provided by their contractors. We have devoted, and will continue to devote, substantial resources toward employee safety and training programs. Although price is generally the primary factor, we believe our clients consider all of these factors price is generally the primary factor in determining which service provider is awarded the work. However, we believework, and that many clients are willing to pay a slight premium for the quality and safe, efficient service we provide.
The drilling contracts we competefollowing is an overview of the market for are usually awarded on the basiseach of competitive bids.our services:
Domestic and International Drilling. Our principal domestic drilling competitors are Helmerich & Payne, Inc., Precision Drilling Corporation, Patterson-UTI Energy, Inc. and Nabors Industries Ltd. In Colombia, we primarily compete with Helmerich & Payne, Inc., Nabors Industries Ltd., Weatherford International plc, Petrex S.A., Tuscany International Drilling, and Estrella International Energy Services Ltd. Our current drilling rig fleet is 100% pad-capable and offers the latest advancements in pad drilling, which we believe positions us well to compete and expand our presence in predominant shale regions.
Well Servicing.The largest well servicing providers that we compete with are Key Energy Services, Basic Energy Services, C&J Energy Services, Superior Energy Services Inc. and CC Forbes.Forbes Energy Services. As compared to the other large competitors in this industry, we believe our fleet is one of the youngest, most uniform fleets, which in addition to our safety performance and service quality, has historically allowed us to operate at utilization and hourly rates that are among the highest of our peers.
Wireline.The wireline market in the United States is dominated by a small number of companies, including ourselves. These competitors include Allied-Horizontal Wireline Services, Renegade Services, C&J Energy Services, KLXNine Energy Services, and Archer Ltd.Quintana Energy Services. Additional competitors include Schlumberger Ltd., Halliburton Company and other independents. The market for wireline services is very competitive, but historically we have competed effectively with our competitors because of the diversified services we provide, our performance and strong client service.
Coiled Tubing.The market for coiled tubing has expanded within the oilfield services market over recent years due to technological advances whichthat increased the numbervariety of applications for the coiled tubing unit and due to the increase in deep well and horizontal drilling. Our primary competitors in the coiled tubing services market currently include C&J Energy Services, Superior Energy Services, Key Energy Services, Schlumberger Ltd., Halliburton Company, Quintana Energy Services and RPC, Inc.
In addition, there are numerous smaller companies that compete in all of our services markets. Some of our competitors have greater financial, technical and other resources than we do. Their greater capabilities in these areas may enable them to:
better withstand industry downturns;

11



compete more effectively on the basis of price and technology;
retain skilled personnel; and

12



build new rigs or acquire and refurbish existing rigs and place them into service more quickly than us in periods of high drilling demand.
The need for our services fluctuates primarily in relation to the price (or anticipated price) of oil and natural gas, which in turn is driven by the supply of and demand for oil and natural gas. The level of our revenues, earnings and cash flows are substantially dependent upon, and affected by, the level of domestic and international oil and gas exploration and development activity, as well as the equipment capacity in any particular region. For a more detailed discussion, see Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
Raw Materials
The materials and supplies we use in our drilling and production services operations include fuels to operate our equipment, drilling mud, drill pipe, drill collars, drill bits, cement and other job materials such as explosives, perforating guns and coiled tubing. We do not rely on a single source of supply for any of these items. While we are not currently experiencing any shortages, fromFrom time to time, there have been shortages of drilling and production services equipment and supplies during periods of high demand.

In addition, during periods of shortages,clients and could substantially lengthen the delivery times for equipment and supplies can be substantially longer.supplies. Any significant delays in our obtaining equipment or supplies could limit our operations and jeopardize our relations with clients. In addition, shortages of equipment or suppliesclients and could delay and adversely affect our ability to obtain new contracts for our rigs, whichrigs. Any of the above could have a material adverse effect on our financial condition and results of operations.
Operating Risks and Insurance
Our operations are subject to the many hazards inherent in exploration and production activity, including the risks of:
blowouts;
cratering;
fires and explosions;
loss of well control;
collapse of the borehole;
damaged or lost drilling equipment; and
damage or loss from natural disasters.
Any of these hazards can result in substantial liabilities or losses to us from, among other things:
suspension of operations;
damage to, or destruction of, our property and equipment and that of others;
personal injury and loss of life;
damage to producing or potentially productive oil and gas formations through which we drill; and
environmental damage.
We seek to protect ourselves from some but not all operating hazards through insurance coverage. However, some risks are either not insurable or insurance is available only at rates that we consider uneconomical. Those risks include, among other things, pollution liability in excess of relatively low limits. Depending on competitive conditions and other factors, we attempt to obtain contractual protection against uninsured operating risks from our clients. However, clients who provide contractual indemnification protection may not in all cases maintain adequate insurance or otherwise have the financial resources necessary to support their indemnification obligations. Our insurance or indemnification arrangements may not adequately protect us against liability or loss from all the hazards of our operations. The occurrence of a significant event that we have not fully insured or indemnified against or the failure of a client to meet its indemnification obligations to us could materially and adversely affect our results of operations and financial condition. Furthermore, we may be unable to maintain adequate insurance in the future at rates we consider reasonable.
Our current insurance coverage includes property insurance on our rigs, drilling equipment, production services equipment and real property. Our insurance coverage for property damage to our rigs, drilling equipment and production services equipment is based on our estimates of the cost of comparable used equipment to replace the insured property. The policy provides for a deductible of no more than $750,000 per drilling rig and a deductible on production services equipment of $250,000100,000 per occurrence. Our third-party liability insurance coverage is $101 million per occurrence and

in the aggregate, with a deductible of $250,000 per occurrence.occurrence and an additional $250,000 annual aggregate deductible. We also carry insurance coverage for pollution liability up to $20 million with a deductible of $500,000. We believe that we are adequately

12



insured for public liability and property damage to others with respect to our operations. However, such insurance may not be sufficient to protect us against liability for all consequences of well disasters, extensive fire damage or damage to the environment.
In addition, we generally carry insurance coverage to protect against certain hazards inherentEmployees
We currently have approximately 2,400 employees, the majority of which work in our turnkey contract drilling operations. This insurance covers “control-of-well,” including blowouts above and below the surface, redrilling, seepage and pollution. This policy provides coverage of $3 million to $20 million, subject to a deductible of $150,000 or $250,000, depending on the area in which the well is drilled and its target depth. This policy also provides care, custody and control insurance, with a limit of $1 million, subject to a $100,000 deductible.
Employees
We have approximately 1,800 employees, which is down by over 50% from the beginning of 2015. The majority of our employees work inproduction services operations for our Drilling Services Segment and Production Services Segment and are primarily compensated on an hourly basis. The number of employees in operations fluctuates depending on the utilization of our drilling rigs, well servicing rigs, wireline units and coiled tubing units at any particular time. None of our employment arrangements are subject to collective bargaining arrangements.
Our operations require the services of employees having the technical training and experience necessary to achieve proper operational standards.results. As a result, our operations depend, to a considerable extent, on the continuing availability of such personnel. Although we have not encountered material difficulty in hiring and retaining employees in our operations,From time to time, shortages of qualified personnel have occurred in our industry. If we should suffer any material loss of personnel to competitors or be unable to employ additional or replacement personnel with the requisite level of training and experience to adequately operate our equipment, our operations could be materially and adversely affected. While we believe our wage rates are competitive and our relationships with our employees are satisfactory, a significant increase in the wages paid by other employers could result in a reduction in our workforce, increases in wage rates, or both. The occurrence of either of these events for a significant period of time could have a material adverse effect on our financial condition and results of operations.
Facilities
Facilities
We lease our corporate office facilities located at 1250 N.E. Loop 410, Suite 1000 San Antonio, Texas 78209. We conduct our business operations through 53 other real estate locations, of which we own 12, in29 regional offices throughout the United States (Texas,in Texas, Oklahoma, Colorado, Montana, North Dakota, Pennsylvania, Wyoming, Mississippi, Arkansas, Louisiana and Kansas)Kansas, and internationally in Colombia. These operating locations typically include leased real estate locationsproperties which are primarily used for regional offices, and storage and maintenance yards.yards and personnel housing sufficient to support our operations in the area. We own 12 real estate properties associated with our regional operations.
Governmental Regulation
Many aspects of our operations are subject to various federal, state and local laws and governmental regulations, including laws and regulations governing:
environmental quality;
pollution control;
remediation of contamination;
preservation of natural resources;
transportation; and
worker safety.
Environment Protection. Our operations are subject to stringent federal, state and local laws, rules and regulations governing the protection of the environment and human health and safety.
Some of thosethe laws, rules and regulations applicable to our industry relate to the disposal of hazardous substances, oilfield waste and other waste materials and restrict the types, quantities and concentrations of those substances that can be released into the environment. Several of those laws also require removal and remedial action and other cleanup under certain circumstances, commonly regardless of fault. Our operations routinely involve the handling of significant amounts of waste materials, some of which are classified as hazardous wastes and/or hazardous substances. Planning, implementation and maintenance of protective measures are required to prevent accidental discharges. Spills of oil, natural gas liquids, drilling fluids and other substances may subject us to penalties and cleanup requirements. Handling, storage and disposal of both hazardous and non-hazardous wastes are also subject to these regulatory requirements. In addition, our operations are often conducted in or near ecologically sensitive areas, such as wetlands, which are subject

14



to special protective measures and which may expose us to additional operating costs and liabilities for accidental discharges of oil, gas, drilling fluids, contaminated water or other substances, or for noncompliance with other aspects of applicable laws and regulations.
Environmental laws and regulations are complex and subject to frequent change. Failure to comply with governmental requirements or inadequate cooperation with governmental authorities could subject a responsible party to administrative, civil or criminal action. We may also be exposed to environmental or other liabilities originating from businesses and assets

13



which we acquired from others. Our compliance with amended, new or more stringent requirements, stricter interpretations of existing requirements or the future discovery of contamination or regulatory noncompliance may require us to make material expenditures or subject us to liabilities that we currently do not anticipate.
There are a variety of regulatory developments, proposals or requirements and legislative initiatives that have been introduced in the United States and international regions in which we operate that are focused on restricting the emission of carbon dioxide, methane and other greenhouse gases.
Hydraulic fracturing of wells and subsurface water disposal are also under public and governmental scrutiny due to concerns regarding potential environmental and physical impacts, including groundwater and drinking water impacts, as well as whether such activities may cause earthquakes. Increased regulation and attention given to the hydraulic fracturing process could lead to greater opposition, including litigation, to oil and gas production activities using hydraulic fracturing techniques. Additional legislation or regulation could also lead to operational delays or increased operating costs in the production of oil and natural gas, including from the developing shale plays, incurred by our clients. The adoption of any federal, state or local laws or the implementation of regulations or ordinances restricting or increasing the costs of hydraulic fracturing could cause a decrease in the completion of new oil and natural gas wells and an associated decrease in demand for our drilling and well servicing activities, any or all of which could adversely affect our financial position, results of operations and cash flows.
Our wireline operations involve the use of radioactive isotopes along with other nuclear, electrical, acoustic, and mechanical devices. Our activities involving the use of isotopes are regulated by the U.S. Nuclear Regulatory Commission and specified agencies of certain states. Additionally, we use high explosive charges for perforating casing and formations, and we use various explosive cutters to assist in wellbore cleanout. Such operations are regulated by the U.S. Department of Justice, Bureau of Alcohol, Tobacco, Firearms, and Explosives and require us to obtain licenses or other approvals for the use of densitometers as well as explosive charges. We have obtained these licenses and approvals when necessary and believe that we are in substantial compliance with these federal requirements.
In addition, our business depends on the demand for land drilling and production services from the oil and gas industry and, therefore, is affected by tax, environmental and other laws relating to the oil and gas industry generally, by changes in those laws and by changes in related administrative regulations. It is possible that these laws and regulations may in the future add significantly to our operating costs or those of our clients, or otherwise directly or indirectly affect our operations.
See Item 1A—“Risk Factors” in Part I of this Annual Report on Form 10-K for a detailed discussion of risks we face concerning laws and governmental regulations.
Transportation.Among the services we provide, we operate as a motor carrier for the transportation of our own equipment and therefore are subject to regulation by the U.S. Department of Transportation and by various state agencies. These regulatory authorities exercise broad powers, governing activities such as the authorization to engage in motor carrier operations and regulatory safety. There are additional regulations specifically relating to the trucking industry, including testing and specification of equipment and product handling requirements. The trucking industry is subject to possible regulatory and legislative changes that may affect the economics of the industry by requiring changes in operating practices or by changing the demand for common or contract carrier services or the cost of providing truckload services. Some of these possible changes include increasingly stringent environmental regulations, changes in the hours of service regulations which govern the amount of time a driver may drive in any specific period, onboard black box recorder devices or limits on vehicle weight and size.
Interstate motor carrier operations are subject to safety requirements prescribed by the U.S. Department of Transportation. To a large degree, intrastate motor carrier operations are subject to state safety regulations that mirror federal regulations. Such matters as weight and dimension of equipment are also subject to federal and state regulations.
From time to time, various legislative proposals are introduced, including proposals to increase federal, state, or local taxes, including taxes on motor fuels, which may increase our costs or adversely impact the recruitment of drivers. We cannot predict whether, or in what form, any increase in such taxes applicable to us will be enacted.

Risk FactorsRISK FACTORS
The information set forth in this Item 1A should be read in conjunction with the rest of the information included in this report, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 and the financial statements and related notes this report contains. While we attempt to identify, manage and mitigate risks and uncertainties associated with our business to the extent practical under the circumstances, some level of risk and uncertainty will always be present. Additional risks and uncertainties that are not presently known to us or that we currently believe are immaterial also may negatively impact our business, financial condition or operating results.
Set forth below are various risks and uncertainties that could adversely impact our business, financial condition, results of operations and cash flows.
Risks Relating to the Oil and Gas Industry
We derive all our revenues from companies in the oil and gas exploration and production industry, a historically cyclical industry with levels of activity that are significantly affected by the levels and volatility of oil and gas prices.
As a provider of contract land drilling services and oil and gas production services, our business depends on the level of exploration and production activity in the geographic markets where we operate. The oil and gas exploration and production industry is a historically cyclical industry characterized by significant changes in the levels of exploration and development activities.
Oil and gas prices, and market expectations of potential changes in those prices, significantly affect the levels of those activities. Oil and gas prices have been volatile historically and, we believe, will continue to be so in the future. Worldwide political, economic, and military events as well as natural disasters have contributed to oil and gas price volatility historically, and are likely to continue to do so in the future. Many factors beyond our control affect oil and gas prices, including:
the worldwide supply and demand for oil and gas;
the cost of exploring for, producing and delivering oil and gas;
the discovery rate of new oil and gas reserves;
the rate of decline of existing and new oil and gas reserves;
available pipeline and other oil and gas transportation capacity;
the levels of oil and gas storage;
the ability of oil and gas exploration and production companies to raise capital;
economic conditions in the United States and elsewhere;
actions by the Organization of Petroleum Exporting Countries, which we refer to as OPEC;
political instability in the Middle East and other major oil and gas producing regions;

16



governmental regulations, both domestic and foreign;
domestic and foreign tax policy;
weather conditions in the United States and elsewhere;
the pace adopted by foreign governments for the exploration, development and production of their national reserves;reserves, or their investments in oil and gas reserves located in other countries; and
the price of foreign imports of oil and gas.
As a result of
15



Additionally, the decline in oil prices that began in late 2014, our clients maintained minimal spending on explorationabove factors can also be affected by technological advances affecting energy consumption and production projects in 2015the supply and 2016, resulting in a continued decrease in demand within the market for our services.renewable energy resources.
Oil and natural gas prices, and market expectations of potential changes in these prices, significantly impact the level of worldwide drilling and production services activities.
Oil and natural gas prices, and market expectations of potential changes in these prices, significantly impact the level of worldwide drilling and production services activities. Reduced demand for oil and natural gas generally results in lower prices for these commodities and often impacts the economics of planned drilling projects and ongoing production projects, resulting in the curtailment, reduction, delay or postponement of such projects for an indeterminate period of time. When drilling and production activity and spending declines, both dayrates and utilization historically decline as well.
Beginning in OctoberIn late 2014, oil prices worldwide dropped significantly. Ourbegan to drop significantly and as a result, our clients significantly reduced both their operating and capital expenditures during 2015 and 2016, but increases are expected for 2017. If the depressedwhich adversely affected our business. In 2017 and 2018, our clients modestly increased their spending as compared to 2016 levels, and our business trended upward as a result. However, in late 2018, oil prices again began to decline and natural gas prices persist foras a prolonged period, or further decline,result, oil and gas exploration and production companies are likely to continue tomay cancel or curtail their drilling programs and further reduce production spending on existing wells, thereby reducing demand for our services.
The reduction in spending and activity levels adversely affected our business during 2015 and 2016. If the reduction in the overall level of exploration and development activities, whether resulting from changes in oil and gas prices or otherwise, continues or worsens, it could materially and adversely affect us further by negatively impacting:
our revenues, cash flows and profitability;
the fair market value of our drilling rig fleet and production services equipment;fleets;
our ability to maintain or increase our borrowing capacity;
our ability to obtain additional capital to finance our business or make acquisitions, and the cost of that capital;
the collectability of our receivables; and
our ability to retain skilled operations personnel whom we would need in the event of an upturn in the demand for our services.personnel.
Risks Relating to Our Business
Reduced demand for or excess capacity of drilling services or production services could adversely affect our profitability.
Our profitability in the future will depend on many factors, but largely on pricing and utilization rates for our drilling and production services. A reduction in the demand for drilling rigs or an increase in the supply of drilling rigs, whether through new construction or refurbishment, could decrease the dayrates and utilization rates for our drilling services, which would adversely affect our revenues and profitability. AnLikewise, an increase in supplyor oversupply of well servicing rigs, wireline units and coiled tubing units, without a corresponding increase inincreased demand, could similarlyfurther decrease the pricing and utilization rates of our production services which wouldand adversely affect our revenues and profitability.
We operate in a highly competitive, fragmented industry in which price competition could reduce our profitability.
We encounter substantial competition from other drilling contractors and other oilfield service companies. Our primary market areas are highly fragmented and competitive. The fact that drilling and production services equipment are mobile and can be moved from one market to another in response to market conditions heightens the competition in the industry and may result in an oversupply of equipment in an area. Contract drilling companies and other oilfield service companies compete primarily on a regional basis, and the intensity of competition may vary significantly from region to region at any particular time. If demand for drilling or production services improves in a region where we operate, our competitors might respond by moving in suitable rigs and production services equipment from other regions. An influx of equipment from other regions could rapidly intensify competition, reduce profitability and make any improvement in demand for our services short-lived.

17



Most drilling services contracts and production services contracts are awarded on the basis of competitive bids, which also results in price competition. In addition to pricing and equipment availability, we believe the following factors are also important to our clients in determining which drilling services or production services provider to select:
the type, capability and condition of each of the competing drilling rigs, well servicing rigs, wireline units and coiled tubing units;
the mobility and efficiency of the equipment;
the quality of service and experience of the crews;
the reputation and safety record of the company providing the services;

16



the offering of integrated and/or ancillary services; and
the ability to provide drilling and production services equipment adaptable to, and personnel familiar with, new technologies and drilling and production techniques.
While we must be competitive in our pricing, our competitive strategy generally emphasizes the quality of our equipment, our safety record, our ability to offer ancillary services, the experience of our crews and the quality of service we provide to differentiate us from our competitors. This strategy is less effective when lower demand for drilling and production services intensifies price competition and makes it more difficult for us to compete on the basis of factors other than price. In all of the markets in which we compete, an oversupply of drilling rigs or production services equipment generally causes greater price competition and reduced profitability.
We face competition from many competitors with greater resources.
Some of our competitors have greater financial, technical and other resources than we do. Their greater capabilities in these areas may enable them to:
better withstand industry downturns;
compete more effectively on the basis of price and technology;
retain skilled personnel; and
build new rigs or acquire and refurbish existing rigs and place them into service more quickly than us in periods of high drilling demand.
Technological advancements and trends in our industry also affect the demand for certain types of equipment, and can affect the overall demand for equipment inthe services our industry.industry provides.
Technological advancements and trends in our industry also affect the demand for certain types of equipment, and can affect the overall demand for equipment inthe services our industry. For several years, prior to late 2014, higher oil prices drove industry equipment utilizationprovides. Enhanced directional and revenue rates up, particularly in oil-producing regions and certain shale regions. However, advancements in technology improved the efficiency ofhorizontal drilling rigs and overall demand remained steady, while the demand for certain drilling rigs decreased, particularly in vertical well markets. The decline was a result of higher demand for drilling rigs that are able to drill horizontally and the increased use of “pad drilling” which enables a series of horizontal wells to be drilled in succession by walking or skidding a drilling rig at a single pad-site location, thereby improving the productivity oftechniques have allowed exploration and production activities. This trend, then coupled with the downturn, resulted in significantly reduced demand for drilling rigs that do not have the ability to walk or skid andoperators to drill horizontal wells,increasingly longer lateral wellbores which enable higher hydrocarbon production per well, and could further reduce the overall number of wells needed to achieve the desired production. This trend toward longer lateral wellbores also increases demand for allthe more specialized equipment, such as high-spec drilling rigs.
In drilling, all rig classes were severely impacted by the industry downturn. However, AC drillingrigs, higher horsepower well servicing rigs equipped with either a walking or skidding system aretaller masts, larger diameter coiled tubing units, and other higher power ancillary equipment, which is needed in order to drill, complete and provide services to the best suited for horizontal padfull length of the wellbore.
Our domestic drilling and we believe theyproduction services fleets are the most desirable rig design available.
highly capable and designed for operation in today’s long lateral, pad-oriented environment. Although we take measures to ensure that we use advanced technologies for drilling and production services equipment, changes in technology or improvements in our competitors’ equipment could make our equipment less competitive or require significant capital investments to keep our equipment competitive, which could have an adverse effect on our financial condition and operating results.

We derive a significant portion of our revenue from a limited number of major clients, and our business, financial condition and results of operations could be materially adversely affected if we are unable to maintain relationships with these clients, or if their demand for our services decreases.
In the past, we have derived a significant portion of our revenue from a limited number of major clients. For the years ended December 31, 20162018, 20152017 and 20142016, our drilling and production services to our top three clients accounted for approximately 26%20%, 29%20%, and 28%26%, respectively, of our revenue. The loss of one or more of our major clients, or their decrease in demand for our services, could have a material adverse effect on our business, financial condition and results of operations. We experienced significantly reduced demand for our services during 2015 and 2016, from all clients, including these major clients. For a detail of our three largest clients as a percentage of our total revenues during the last three fiscal years, see Item 1—“Business” in Part I of this Annual Report on Form 10-K.

Our indebtedness could restrict our operations and make us more vulnerable to adverse economic conditions.
Our indebtedness is primarily a result of the two productionacquisitions of the well servicing and wireline services businesses thatwhich we acquired in 2008 and the acquisition of Go-Coilcoiled tubing business that we acquired in 2011, as well as organic growth investments. At JanuaryDecember 31, 2017,2018, our total debt balance of $349.7 million consists of $300 million outstanding under our Senior Notes and $49.7$175 million outstanding under our Revolving Credit Facility. At January 31, 2017, we hadTerm Loan, with additional borrowing availability of $88.5 millionunder our Revolving CreditABL Facility.
Our current and future indebtedness could have important consequences, including:
limiting our ability to use operating cash flow in other areas of our business because we must dedicate a substantial portion of these funds to make principal and interest payments on our indebtedness;
making us more vulnerable to a downturn in our business, our industry or the economy in general as a substantial portion of our operating cash flow could be required to make principal and interest payments on our indebtedness, making it more difficult to react to changes in our business, industry and market conditions;
limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;
impairing our ability to make investments and obtain additional financing for working capital, capital expenditures, acquisitions or other general corporate purposes;
limiting our ability to obtain additional financing that may be necessary to operate or expand our business;
putting us at a competitive disadvantage to competitors that have less debt; and
increasing our vulnerability to rising interest rates.
We currently expect that cash and cash equivalents, cash generated from operations, proceeds from sales of certain non-strategic assets, and available borrowings under our Revolving CreditABL Facility are adequate to cover our liquidity requirements for at least the next 12 months. However, our ability to make payments on our indebtedness, and to fund planned capital expenditures, will depend on our ability to generate cash in the future. This, to a certain extent, is subject to to:
conditions in the oil and gas industry, industry;
general economic and financial conditions, conditions;
competition in the markets where we operate, operate;
the impact of legislative and regulatory actions on how we conduct our businessbusiness; and
other factors, all of which are beyond our control.
If our business does not generate sufficient cash flow from operations to service our outstanding indebtedness, we may have to undertake alternative financing plans, subject to the limitations imposed by our Term Loan, ABL Facility and Senior Notes, such as:
refinancing or restructuring our debt;
selling assets;
reducing or delaying acquisitions or capital investments, such as refurbishments of our rigs and related equipment; and/or
seeking to raise additional capital.
However, we may be unable to implement alternative financing plans, if necessary, on commercially reasonable terms or at all, and any such alternative financing plans might be insufficient to allow us to meet our debt obligations. If we are unable to generate sufficient cash flow or are otherwise unable to obtain the funds required to make principal and interest payments on our indebtedness, or if we otherwise fail to comply with the various covenants in our Revolving CreditTerm Loan, ABL Facility, or other instruments governing any future indebtedness,and Senior Notes, we could be in default under the terms of our Revolving Credit Facility or such instruments. In the event of a default, theour lenders under our Revolving Credit Facility could elect to declare all the loans made under such facilityour Term Loan, ABL Facility, and Senior Notes to be due and payable together with accrued and unpaid interest and terminate their commitments thereunder and we or one or more of our subsidiaries could be forced into

19



bankruptcy or liquidation. Any of the foregoing consequences could materially and adversely affect our business, financial condition, results of operations and prospects.

18



Our Revolving CreditTerm Loan, ABL Facility, and our Senior Notes impose significant covenants on us that may affect our ability to successfully operate our business.
Our Revolving Credit Facility limitsTerm Loan contains customary restrictions that, among other things, and subject to certain exceptions, limit our ability to take various actions, such as:to:
incur additional debt or make prepayments of existing debt;
createincur or permit liens on or dispose of our assets;
make investments and acquisitions;
consolidate or merge with another company;
engage in asset sales; and
pay dividends on stock or repurchase stock;make distributions.
enter into acquisitions, mergers, consolidations, sale leaseback transactions, or hedging contracts;
make capital expenditures;
make other restricted investments;
conduct transactions with affiliates; and
limits our use of the net proceeds of any offering of our equity securities to the repayment of debt outstanding under the Revolving Credit Facility.
In addition, our Revolving Credit FacilityTerm Loan requires us to maintain certain financial covenants and to satisfy certain financial conditions, which may require us to reduce our debt or take some other action in order to comply with them.
Our ABL Facility contains restrictive covenants that, among other things, and subject to certain exceptions, limit our ability to:
declare dividends and make other distributions;
issue or sell certain equity interests;
optionally prepay, redeem or repurchase certain of our subordinated indebtedness;
make loans or investments (including acquisitions);
incur additional indebtedness or modify the terms of permitted indebtedness;
grant liens;
change our business or the business of our subsidiaries;
merge, consolidate, reorganize, recapitalize, or reclassify our equity interests;
sell our assets, and
enter into certain types of transactions with affiliates.
The Indenture governing our Senior Notes, among other things, limits us and certain of our subsidiaries, subject to certain exceptions, in our ability to:
pay dividends on stock, repurchase stock, redeem subordinated indebtedness or make other restricted payments and investments;
incur, assume or guarantee additional indebtedness or issue preferred or disqualified stock;
create liens on our or their assets;
enter into sale and leaseback transactions;
sell or transfer assets;
borrow, pay dividends, or transfer other assets from certain of our subsidiaries;
consolidate with or merge with or into, or sell all or substantially all of our properties to any other person;
enter into transactions with affiliates; and
enter into new lines of business.
The failure to comply with any of these covenants would cause an event of default under our Revolving CreditTerm Loan, ABL Facility, or our Senior Notes. An event of default, if not waived, could result in acceleration of the outstanding indebtedness, in which case the debt would become immediately due and payable. If this occurs, we may not be able to pay our debt or borrow sufficient funds to refinance it. Even if new financing is available, it may not be available on terms that are acceptable to us. These covenants could also limit our ability to obtain future financing, make needed capital expenditures, withstand a downturn in our business or the economy in general, or otherwise conduct necessary corporate activities. We also may be prevented from taking advantage of business opportunities that arise because of the limitations imposed on us by the restrictive covenants under our Revolving CreditTerm Loan, ABL Facility, and our Senior Notes.
Unexpected cost overruns on our turnkey drilling jobs could adversely affect our financial position and our results of operations.
We have historically derived a portion of our revenues from turnkey drilling contracts, although we do not expect turnkey contracts to represent a significant amount of our revenues in the current industry environment.
Under a typical turnkey drilling contract, we agree to drill a well for our client to a specified depth and under specified conditions for a fixed price. We provide technical expertise and engineering services, as well as most of the equipment and drilling supplies required to drill the well. We often subcontract for related services, such as the provision of casing crews, cementing and well logging. Under typical turnkey drilling arrangements, we do not receive progress payments and are paid by our client only after we have performed the terms of the drilling contract in full. For these reasons, the risk to us under a turnkey drilling contract is substantially greater than for a well drilled on a daywork basis because we must assume most of the risks associated with drilling operations that the operator generally assumes under a daywork contract, including the risks of blowout, loss of hole, stuck drill pipe, machinery breakdowns, abnormal drilling conditions and risks associated with subcontractors’ services, supplies, cost escalations and personnel. In addition, since we are only paid by our clients after we have performed the terms of the drilling contract in full, our liquidity can be affected by the number of turnkey contracts that we enter into.

20



The occurrence of uninsured or under-insured losses or operating cost overruns on our turnkey jobs could have a material adverse effect on our financial position and results of operations. Although we attempt to obtain insurance coverage to reduce certain of the risks inherent in our turnkey drilling operations, adequate coverage may be unavailable in the future and we might have to bear the full cost of such risks, which could have an adverse effect on our financial condition and results of operations.
Our operations involve operating hazards, which, if not insured or indemnified against, could adversely affect our results of operations and financial condition.
Our operations are subject to the many hazards inherent in exploration and production activity, including the risks of:
blowouts;
cratering;
fires and explosions;
loss of well control;

19



collapse of the borehole;
damaged or lost drilling equipment; and
damage or loss from natural disasters.
Any of these hazards can result in substantial liabilities or losses to us from, among other things:
suspension of operations;
damage to, or destruction of, our property and equipment and that of others;
personal injury and loss of life;
damage to producing or potentially productive oil and gas formations through which we drill; and
environmental damage.
We seek to protect ourselves from some but not all operating hazards through insurance coverage. However, some risks are either not insurable or insurance is available only at rates that we consider uneconomical. Those risks include, among other things, pollution liability in excess of relatively low limits. Depending on competitive conditions and other factors, we attempt to obtain contractual protection against uninsured operating risks from our clients. However, clients who provide contractual indemnification protection may not in all cases maintain adequate insurance or otherwise have the financial resources necessary to support their indemnification obligations. Our insurance or indemnification arrangements may not adequately protect us against liability or loss from all the hazards of our operations. The occurrence of a significant event that we have not fully insured or indemnified against or the failure of a client to meet its indemnification obligations to us could materially and adversely affect our results of operations and financial condition. Furthermore, we may be unable to maintain adequate insurance in the future at rates we consider reasonable.
We could be adversely affected if shortages of equipment, supplies or personnel occur.
From time to time, there have been shortages of drilling and production services equipment and supplies during periods of high demand, which we believe could recur. Additionally, trade and economic sanctions or other restrictions imposed by the United States or other countries could also affect the supply of equipment and supplies which are needed in our operations. Shortages could result in increased prices for equipment or supplies that we may be unable to pass on to clients. In addition, during periods of shortages,clients and could substantially lengthen the delivery times for equipment and supplies can be substantially longer.supplies. Any significant delays in our obtaining equipment or supplies could limit our operations and jeopardize our relations with clients. In addition, shortages of equipment or suppliesclients and could delay and adversely affect our ability to obtain new contracts for our rigs, whichrigs. Any of the above could have a material adverse effect on our financial condition and results of operations.
Our strategy of constructing drilling rigs during periods of peak demand requires that we maintain an adequate supply of drilling rig components to complete our rig building program. Our suppliers may be unable to continue providingprovide us the needed drilling rig components if their manufacturing sources are unable to fulfill their commitments.
Our operations require the services of employees having the technical training and experience necessary to achieve the proper operational results. As a result, our operations depend, to a considerable extent, on the continuing availability of such personnel. Shortages of qualified personnel have occurred in our industry. If we should suffer any material loss of personnel to competitors or be unable to employ additional or replacement personnel with the requisite level of training and experience to adequately operate our equipment, our operations could be materially and adversely affected. A significant increase in the wages paid by other employers could result in a reduction in our workforce, increases in

21



wage rates, or both. The occurrence of either of these events for a significant period of time could have a material adverse effect on our financial condition and results of operations.
Our acquisitionlong-term strategy exposesfor growth through acquisitions could expose us to various risks, including those relating to difficulties in identifying suitable acquisition opportunities and integrating businesses, assets and personnel, as well as difficulties in obtaining financing for targeted acquisitions and the potential for increased leverage or debt service requirements.
A component of our long-term business strategy is a pursuit of acquisitions of complementary assets and businesses.businesses, subject to the limitations imposed by our Term Loan, ABL Facility, and Senior Notes. This acquisition strategy in general involves numerous inherent risks, including:
unanticipated costs and assumption of liabilities and exposure to unforeseen liabilities of acquired businesses, including environmental liabilities;
difficulties in integrating the operations and assets of the acquired business and the acquired personnel;

20



limitations on our ability to properly assess and maintain an effective internal control environment over an acquired business in order to comply with applicable periodic reporting requirements;
potential losses of key employees and clients of the acquired businesses;
risks of entering markets in which we have limited prior experience; and
increases in our expenses and working capital requirements.
The process of integrating an acquired business may involve unforeseen costs and delays or other operational, technical and financial difficulties that may require a disproportionate amount of management attention and financial and other resources. Our failure to achieve consolidation savings, to incorporate the acquired businesses and assets into our existing operations successfully or to minimize any unforeseen operational difficulties could have a material adverse effect on our financial condition and results of operations.
In addition, we may not have sufficient capital resources to complete additional acquisitions. Historically, we have funded business acquisitions and the growth of our rig fleetfleets through a combination of debt and equity financing. We may incur substantial additional indebtedness to finance future acquisitions and also may issue equity securities or convertible securities in connection with such acquisitions. Debt service requirements could represent a significant burden on our results of operations and financial condition and the issuance of additional equity or convertible securities could be dilutive to our existing shareholders. Furthermore, we may not be able to obtain additional financing on satisfactory terms or at all.
Even if we have access to the necessary capital, we may be unable to continue to identify additional suitable acquisition opportunities, negotiate acceptable terms or successfully acquire identified targets.
Our cash and cash equivalents and short term investments could be adversely affected if the financial institutions in which we hold our cash and cash equivalents fail.
We maintain cash balances at third-party financial institutions in excess of the Federal Deposit Insurance Corporation insurance limit. While we monitor the cash balances in the operating accounts and adjust the balances as appropriate, we may incur a loss to the extent such loss exceeds the insurance limitation, and there could be a material impact on our business, if one ofor more of the financial institutions with which we deposit fails or is subject to other adverse conditions in the financial or credit markets and bank regulators elect to impose losses on uninsured depositors. To date, we have experienced no loss or lack of access to our invested cash or cash equivalents. However, in the future, our invested cash and cash equivalents could be adversely affected by adverse conditions in the financial and credit markets.
Our international operations are subject to political, economic and other uncertainties not generally encountered in our domestic operations.
Our international operations are subject to political, economic and other uncertainties not generally encountered in our U.S. operations which include, among potential others:
risks of war, terrorism, civil unrest and kidnapping of employees;
employee strikes, work stoppages, labor disputes and other slowdowns;
expropriation, confiscation or nationalization of our assets;
renegotiation or nullification of contracts;
foreign taxation, such as the tax for equality and the net-worth tax in Colombia;

22



the inability to repatriate earnings or capital due to laws limiting the right and ability of foreign subsidiaries to pay dividends and remit earnings to affiliated companies;
changing political conditions and changing laws and policies affecting trade and investment;
trade and economic sanctions or other restrictions imposed by the United States or other countries;
concentration of clients;
regional economic downturns;
the overlap of different tax structures;
the burden of complying with multiple and potentially conflicting laws;
the risks associated with the assertion of foreign sovereignty over areas in which our operations are conducted;
the risks associated with any lack of compliance with the Foreign Corrupt Practices Act of 1977 (“FCPA”) or other anti-corruption laws;
the risks associated with fluctuating currency values, hard currency shortages and controls of foreign currency exchange, and higher rates of inflation as compared to our domestic operations;

21



difficulty in collecting international accounts receivable; and
potentially longer payment cycles.
Additionally, we may be subject to foreign governmental regulations favoring or requiring the awarding of contracts to local contractors or requiring foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These regulations could adversely affect our ability to compete.
We are committed to doing business in accordance with applicable anti-corruption laws and our code of conduct and ethics. We are subject, however, to the risk that our employees and agents may take action determined to be in violation of anti-corruption laws, including the FCPA or other similar laws. Any violation of the FCPA or other applicable anti-corruption laws could result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might materially adversely affect our business, results of operations or financial condition. In addition, actual or alleged violations could damage our reputation and ability to do business. Further, detecting, investigating, and resolving actual or alleged violations is expensive and can consume significant time and attention of our senior management.
Our operations are subject to various laws and governmental regulations that could restrict our future operations and increase our operating costs.
Many aspects of our operations are subject to various federal, state and local laws and governmental regulations, including laws and regulations governing:
environmental quality;
pollution control;
remediation of contamination;
preservation of natural resources;
transportation; and
worker safety.
Environment Protection. Our operations are subject to stringent federal, state and local laws, rules and regulations governing the protection of the environment and human health and safety.
Some of thosethe laws, rules and regulations applicable to our industry relate to the disposal of hazardous substances, oilfield waste and other waste materials and restrict the types, quantities and concentrations of those substances that can be released into the environment. Several of those laws also require removal and remedial action and other cleanup under certain circumstances, commonly regardless of fault. Our operations routinely involve the handling of significant amounts of waste materials, some of which are classified as hazardous wastes and/or hazardous substances. Planning, implementation and maintenance of protective measures are required to prevent accidental discharges. Spills of oil, natural gas liquids, drilling fluids and other substances may subject us to penalties and cleanup requirements. Handling, storage and disposal of both hazardous and non-hazardous wastes are also subject to these regulatory requirements. In addition, our operations are often conducted in or near ecologically sensitive areas, such as wetlands, which are subject to special protective measures and which may expose us to additional operating costs and liabilities for accidental discharges of oil, gas, drilling fluids, contaminated water or other substances, or for noncompliance with other aspects of applicable laws and regulations.
The federal Clean Water Act,Act; the Oil Pollution Act (and interpreted by EPA through regulations, including the Clean Water Rule issued in May 2015);Act; the federal Clean Air Act; the federal Resource Conservation and Recovery Act; the federal Comprehensive Environmental Response, Compensation, and Liability Act or CERCLA;(CERCLA); the Safe

23



Drinking Water Act or SDWA;(SDWA); the federal Outer Continental Shelf Lands Act; the Occupational Safety and Health Act or OSHA;(OSHA); regulations implementing these federal statutes (such as the 2015 Waters of the United States rule, which may be rescinded pursuant to a proposal issued in June 2017); and their state counterparts and similar statutes are the primary statutes that impose the requirements described above and provide for civil, criminal and administrative penalties and other sanctions for violation of their requirements. The OSHA hazard communication standard, the Environmental Protection Agency (EPA) “community right-to-know” regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require us to organize and report information about the hazardous materials we use in our operations to employees, state and local government authorities and local citizens. In addition, CERCLA, also known as the “Superfund” law, and similar state statutes impose strict liability, without regard to fault or the legality of the original conduct, on certain classes of persons who are considered responsible for the release or threatened release of certain hazardous substances into the environment. These persons generally include the current owner or operator of a facility where a release has occurred, the owner or operator of a facility at the time

22



a release occurred, and companies that disposed of or arranged for the disposal of hazardous substances found at a particular site. This liability may be joint and several. Such liability, which may be imposed for the conduct of others and for conditions others have caused, includes the cost of removal and remedial action as well as damages to natural resources. Few defenses exist to the liability imposed by many environmental laws and regulations. It is also common for third parties to file claims for personal injury and property damage caused by substances released into the environment.
Environmental laws and regulations are complex and subject to frequent change. Failure to comply with governmental requirements or inadequate cooperation with governmental authorities could subject a responsible party to administrative, civil or criminal action. We may also be exposed to environmental or other liabilities originating from businesses and assets which we acquired from others. Our compliance with amended, new or more stringent requirements, stricter interpretations of existing requirements or the future discovery of contamination or regulatory noncompliance may require us to make material expenditures or subject us to liabilities that we currently do not anticipate.
There are a variety of regulatory developments, proposals or requirements and legislative initiatives that have been introduced in the United States and international regions in which we operate that are focused on restricting the emission of carbon dioxide, methane and other greenhouse gases. Among these developments at the international level is the United Nations Framework Convention on Climate Change, which produced the “Kyoto Protocol” (an internationally applied protocol, which has been ratified in Colombia, which is a location where we provide drilling services) in 1992. More recently, onin December 12, 2015, 195 countries adopted under the Framework Convention a resolution known as the “Paris Agreement” to reduce emissions of greenhouse gases with a goal of limiting global warming to below 2 °C (3.6 °F). The Paris Agreement does not establish enforceable emissions reduction targets, but countries may establish greenhouse gas reduction measures pursuant to the agreement. The agreement went into effect onin November 4, 2016.
The United States ratified the Paris Agreement in September 2016. It has since notified the United Nations of its intent to withdraw from the Paris Agreement, but under the terms of the agreement the U.S. will remain a party until approximately August 2020.
In addition, the U.S. Congress has from time to time considered legislation to reduce emissions of greenhouse gases, primarily through the development of greenhouse gas cap and trade programs. Also, more than one-third of the states already have begun implementing legal measures to reduce emissions of greenhouse gases. There have been two multi-state organizations devoted to climate action. The Regional Greenhouse Gas Initiative or “RGGI,”(RGGI) is located in the Northeastern and Mid-Atlantic United States. The Western Regional Climate Action Initiative once included multiple U.S. states and much of Canada but allowance trading is now comprised oflimited to only California British Columbia, Manitoba, Ontario, and Quebec.
In 2007, the United States Supreme Court, in Massachusetts, et al. v. EPA, held that carbon dioxide may be regulated as an “air pollutant” under the federal Clean Air Act. OnIn December 7, 2009, the EPA responded to the Massachusetts, et al. v. EPAthis decision and issued a finding that the current and projected concentrations of greenhouse gases in the atmosphere threaten the public health and welfare of current and future generations, and that certain greenhouse gases from motor vehicles contribute to the atmospheric concentrations of greenhouse gases and hence to the threat of climate change.
Based on these findings, in 2010 Subsequently, the EPA adopted two setshas a number of climate change regulations, that restrict emissions of greenhouse gases under existing provisions of the federal Clean Air Act, including one that requires a reduction in emissions of greenhouse gases from motor vehicles and another that requires certain construction and operating permit reviews for greenhouse gas emissions from certain large stationary sources. In June 2014, the U.S. Supreme Court invalidated elements of the greenhouse gascontrol and permitting rule; however, the EPA can still impose certain greenhouse gas control requirements for certain large stationary sources.sources, fuel economy standards for vehicles and emissions standards for power plants. In addition,August 2016, the EPA then adopted rules requiring the monitoring“Phase 2” standards for medium and

24



heavy-duty vehicles through model year 2017.
reporting of greenhouse gases from certain sources, including, among others, onshore oil and natural gas production facilities.
In April 2012, the EPA issued regulations specifically applicableSpecific to the oil and gas industry, that will require operatorsin April 2012, the EPA issued regulations to significantly reduce volatile organic compounds, or VOC, emissions from natural gas wells that are hydraulically fractured through the use of “green completions” to capture natural gas that would otherwise escape into the air. The EPA also issued regulations that establish standards for VOC emissions from several types of equipment at natural gas well sites, including storage tanks, compressors, dehydrators and pneumatic controllers.
On August 3, 2015, In May 2016, the EPA finalized rules to limit carbon dioxide emissions from new and existing electric utility generating units. New units must meet specified carbon dioxide emissions limitations. The rules for existing units, known as the “Clean Power Plan,” will require by 2030 an overall reduction in carbon dioxide emissions of 32% below the amount of carbon dioxide emitted in 2005.
On August 18, 2015, the EPA proposedissued a rule to reduce methane (a greenhouse gas) and VOC emissions from additional oil and gas operations. Among other requirements, the proposed rules would impose standards for hydraulically fractured oil wells and equipment leaks at oil and gas production sites and would extend certain existing standards to downstream oil and gas operations. In April 2017, the EPA granted reconsideration of aspects of this rule.
Although it is not possible at this time to predict whether proposed climate change initiatives will be adopted as initially written, if at all, or how legislation or new regulations that may be adopted to address greenhouse gas emissions would impact our business, any such future laws and regulations could result in increased compliance costs or additional operating restrictions. Any additional costs or operating restrictions associated with legislation or regulations regarding greenhouse gas emissions could have a material adverse effect on our operating results and cash flows. In addition,

23



these developments could curtail the demand for fossil fuels such as oil and gas in areas of the world where our clients operate and thus adversely affect demand for our services, which may in turn adversely affect our future results of operations. Finally, we cannot predict with any certainty whether changes to temperature, storm intensity or precipitation patterns as a result of climate change will have a material impact on our operations.
In addition, our business depends on the demand for land drilling and production services from the oil and gas industry and, therefore, is affected by tax, environmental and other laws relating to the oil and gas industry generally, by changes in those laws and by changes in related administrative regulations. It is possible that these laws and regulations may in the future add significantly to our operating costs or those of our clients, or otherwise directly or indirectly affect our operations.
Oil and gas development restrictions are also possible due to voter initiatives. For example, in 2018, Colorado voted on Proposition 112, which would have increased drilling location setbacks from 500 feet to 2,500 feet, severely limiting access to oil and gas minerals. Although Proposition 112 was defeated, future voter initiatives are possible in certain jurisdictions. Further, state legislators and regulators could seek to impose similar restrictions.
Our wireline operations involve the use of radioactive isotopes along with other nuclear, electrical, acoustic, and mechanical devices. Our activities involving the use of isotopes are regulated by the U.S. Nuclear Regulatory Commission and specified agencies of certain states. Additionally, we use high explosive charges for perforating casing and formations, and we use various explosive cutters to assist in wellbore cleanout. Such operations are regulated by the U.S. Department of Justice, Bureau of Alcohol, Tobacco, Firearms, and Explosives and require us to obtain licenses or other approvals for the use of densitometers as well as explosive charges. We have obtained these licenses and approvals when necessary and believe that we are in substantial compliance with these federal requirements.
Transportation. Among the services we provide, we operate as a motor carrier for the transportation of our own equipment and therefore are subject to regulation by the U.S. Department of Transportation and by various state agencies. These regulatory authorities exercise broad powers, governing activities such as the authorization to engage in motor carrier operations and regulatory safety. There are additional regulations specifically relating to the trucking industry, including testing and specification of equipment and product handling requirements. The trucking industry is subject to possible regulatory and legislative changes that may affect the economics of the industry by requiring changes in operating practices or by changing the demand for common or contract carrier services or the cost of providing truckload services. Some of these possible changes include increasingly stringent environmental regulations, changes in the hours of service regulations which govern the amount of time a driver may drive in any specific period, onboard black box recorder devices or limits on vehicle weight and size.
Interstate motor carrier operations are subject to safety requirements prescribed by the U.S. Department of Transportation. To a large degree, intrastate motor carrier operations are subject to state safety regulations that mirror federal regulations. Such matters as weight and dimension of equipment are also subject to federal and state regulations.

25



From time to time, various legislative proposals are introduced, including proposals to increase federal, state, or local taxes, including taxes on motor fuels, which may increase our costs or adversely impact the recruitment of drivers. We cannot predict whether, or in what form, any increase in such taxes applicable to us will be enacted.
Federal and state legislative and regulatory initiatives related to hydraulic fracturing could result in operating restrictions or delays in the completion of oil and natural gas wells that may reduce demand for our drilling and well servicing activities and could adversely affect our financial position, results of operations and cash flows.
Hydraulic fracturing is a commonly used process that involves injection of water, sand, and a minor amount of certain chemicals to fracture the hydrocarbon-bearing rock formation to allow flow of hydrocarbons into the wellbore. Federal agencies have adopted new rules, such as the Bureau of Land Management’s (BLM) hydraulic fracturing rule finalized in March 2015, that impose additional requirements on the practice of hydraulic fracturing. In December 2017, the BLM rescinded this rule, but litigation is pending to reinstate the rule. In October 2016, the BLM updated its rules to restrict flaring associated with the development of oil and natural gas on public lands, including through hydraulic fracturing. The BLM has since proposed rescinding portions of the rule and portions of the rule have been suspended pending the outcome of litigation concerning the rule. Additional federal regulations may also be developed. Several states are considering legislation to regulate hydraulic fracturing practices that could impose more stringent permitting, transparency, and well construction requirements on hydraulic-fracturing operations or otherwise seek to ban fracturing activities altogether. Hydraulic fracturing of wells and subsurface water disposal are also under public and governmental

24



scrutiny due to concerns regarding potential environmental and physical impacts, including groundwater and drinking water impacts, as well as whether such activities may cause earthquakes.
The federal Energy Policy Act of 2005 amended the Underground Injection Control provisions of the federal Safe Drinking Water Act (SDWA) to exclude certain hydraulic fracturing practices from the definition of “underground injection.” The EPA has asserted regulatory authority over certain hydraulic fracturing activities involving diesel fuel and has developed guidance relating to such practices. In addition, repeal of the SDWA exclusion of hydraulic fracturing has been advocated by certain advocacy organizations and others in the public. Congress has from time to time considered legislation to repeal the exemption for hydraulic fracturing from the SDWA, which would have the effect of allowing the EPA to promulgate new regulations and permitting requirements for hydraulic fracturing, and to require the disclosure of the chemical constituents of hydraulic fracturing fluids to a regulatory agency, which would make the information public via the Internet. For example, in May 2014, the EPA responded to a petition by environmental groups by issuing an Advanced Notice of Proposed Rulemaking (“ANPR”) to solicit input regarding whether the agency should require manufacturers and processors of hydraulic fracturing chemicals to report composition and usage of such chemicals and and to disclose associated health and safety studies.
ScrutinyAlthough the ANPR did not result in a new rule, scrutiny of hydraulic fracturing activities continues in other ways, with the EPA having completed a multi-year study of the potential environmental impacts of hydraulic fracturing. The Final Report issued by the EPA in December 2016 concluded that hydraulic fracturing activities can impact drinking water resources under some circumstances and identified conditions under which impacts can be more frequent or severe. In addition, in April 2012, the EPA issued the first federal air standards for natural gas wells that are hydraulically fractured, which will require operators to significantly reduce VOC emissions through the use of “green completions” to capture natural gas that would otherwise escape into the air. These new rules address emissions of various pollutants frequently associated with oil and natural gas production and processing activities by, among other things, requiring new or reworked hydraulically-fractured gas wells to control emissions through flaring until 2015, after whichor reduced emission (or “green”) completions must be used.completions. The rules also establish specific new requirements, which were effective in 2012, for emissions from compressors, controllers, dehydrators, storage tanks, gas processing plants, and certain other equipment. On September 23, 2013, theThe EPA published amendments to the rule which would, among other things, provide additional time for recently constructed, modified or reconstructed storage tanks to install emission controls. On December 19, 2014, the EPA published a final rule clarifying certain aspects of the new rules. Onhas amended these rules several times. In May 12, 2016, the EPA finalized a rule to reduce methane (a greenhouse gas) and VOC emissions from oil and gas operations. It is also possible that the EPA will further amend its oil and gas regulations. In this regard, in September 2016, the EPA published notice that it would begin to collect information on methane emissions from 15,000 oil and gas operators relating to almost 700,000 oil and gas facilities. These rules may require a number of modifications to our clients’ and our own operations, including the installation of new equipment to control emissions. Compliance with such rules could result in additional costs for us and our clients, including increased capital expenditures and operating costs, which may adversely impact our cash flows and results of operations.
The EPA has also developed effluent limitations for the treatment and discharge of wastewater resulting from hydraulic fracturing activities to publicly owned treatment works (POTW). The agency’s final regulations, published on June 28, 2016, prohibited any discharge of wastewater pollutants from onshore unconventional oil and gas extraction

26



facilities to a POTW. The EPA will also be assessing whether oil and gas wastes should continue to be exempt from being considered hazardous waste under the federal Resource Conservation and Recovery Act, pursuant to a Consent Decree with environmental groups approved in federal court onin December 28, 2016.2016, with a court-imposed deadline of March 2019. The U.S. Department of the Interior has also finalized regulations relating to the use of hydraulic fracturing techniques on public lands and disclosure of fracturing fluid constituents (i.e. the BLM’s hydraulic fracturing rule issued in March 2015) and has conducted hearings onfinalized, in October 2016, a rule to reduce flaring and venting associated with oil and gas operations on public lands. A final version of the flaring and venting rule was issued in October 2016.The BLM rules have since been partially or wholly rescinded or delayed, but it is possible that they will be reinstated through litigation.
In addition, some states and localities have adopted, and others are considering adopting, regulations or ordinances that could restrict hydraulic fracturing in certain circumstances, that would require, with some exceptions, disclosure of constituents of hydraulic fracturing fluids, or that would impose higher taxes, fees or royalties on natural gas production. Moreover, public debate over hydraulic fracturing and shale gas production continued to see strong public opposition, and has resulted in delays of well permits in some areas.
OnIn June 30, 2014, the State of New York’s Court of Appeals upheld the right of individual municipalities in the State of New York to ban hydraulic fracturing using zoning restrictions. In December 2014, New York State Governor Cuomo announced that hydraulic fracturing will be permanently banned in the state. Similarly situated municipalities in other states may seek to ban or restrict resource extraction operations within their borders using zoning and/or setback restrictions, which could adversely affect the ability of resource extraction enterprises to operate in certain parts of the

25



country, and thus adversely affect demand for our services, which may in turn adversely affect our future results of operations.
Increased regulation and attention given to the hydraulic fracturing process could lead to greater opposition, including litigation, to oil and gas production activities using hydraulic fracturing techniques. Additional legislation or regulation could also lead to operational delays or increased operating costs in the production of oil and natural gas, including from the developing shale plays, incurred by our clients. The adoption of any federal, state or local laws or the implementation of regulations or ordinances restricting or increasing the costs of hydraulic fracturing could cause a decrease in the completion of new oil and natural gas wells and an associated decrease in demand for our drilling and well servicing activities, any or all of which could adversely affect our financial position, results of operations and cash flows.
Our operations are subject to the risk of cyber attacks that could have a material adverse effectcybersecurity risks.
Our operations are increasingly dependent on our consolidated results of operationsinformation technologies and consolidated financial condition.
Ourservices.  Threats to information technology systems are subjectassociated with cybersecurity risks and cyber incidents or attacks continue to possible breachesgrow, and other threats that could cause us harm. If our systems for protecting against cyber security risks prove not to be sufficient, we could be adversely affected by,include, among other things, storms and natural disasters, terrorist attacks, utility outages, theft, viruses, malware, design defects, human error, or complications encountered as existing systems are maintained, repaired, replaced, or upgraded. Risks associated with these threats include, among other things:
loss, corruption, or misappropriation of intellectual property, or other proprietary or confidential information (including client, supplier, or employee data);
disruption or impairment of our and our customers’ business operations and safety procedures;
loss or damage of intellectual property, proprietary information, customer or personnel data; interruption of business operations; or additionalto our worksite data delivery systems; and
increased costs to prevent, respond to or mitigate cybersecurity events.
Although we utilize various procedures and controls to mitigate our exposure to such risk, cybersecurity attacks and other cyber security attacks. These risksevents are evolving and unpredictable. Moreover, we do not have control over the information technology systems of our clients, suppliers, and others with which our systems may connect and communicate. As a result, the occurrence of a cyber incident could go unnoticed for a period time. Any such incident could have a material adverse effect on our business, financial condition and resultresults of operations.
Our ability to use our net operating loss and tax credit carryforwards might be limited.
Section 382 of the U.S. Internal Revenue Code contains rules that limit the ability of a company that undergoes an ownership change to utilize its net operating losses and tax credit carryforwards existing as of the date of such ownership change. Under the rules, such an ownership change is generally any change in ownership of more than 50% of a company’s stock within a rolling three-year period. The rules generally operate by focusing on changes in ownership among shareholders owning, directly or indirectly, 5% or more of the stock of a company and any change in ownership arising from new issuances of stock by the company.
If we were to undergo one or more “ownership changes” as defined by Section 382, our net operating losses and certain of our tax credits existing as of the date of each ownership change may be unavailable, in whole or in part, to offset U.S. federal income tax resulting from our operations or any gains from the disposition of any of our assets and/or business, which could result in increased U.S. federal income tax liability.
If we implement an enterprise resource planning system, such implementation could expose us to certain risks commonly associated with the conversion of existing data and processes to a new system.
We are currently in the selection and evaluation phase of implementing a company-wide enterprise resource planning (ERP) system to upgrade, replace and integrate certain existing business, operational and financial processes and systems, upon which we rely. ERP implementations are complex and time-consuming projects that require transformations of business and finance processes in order to reap the benefits of an integrated ERP system. Any such project involves certain risks inherent in the conversion, including loss of information and potential disruption to normal operations and finance functions. Additionally, if the ERP system is not effectively implemented as planned, or the system does not operate as intended, the effectiveness of our internal control over financial reporting could be adversely affected or our ability to assess those controls adequately could be delayed. In addition, if we experience interruptions in service or operational difficulties and are unable to effectively manage our business during or following the implementation of the ERP system, our business and results of operations could be adversely impacted.

Risks Relating to Our Capitalization and Organizational Documents
We do not intend to pay dividends on our common stock in the foreseeable future, and therefore only appreciation of the price of our common stock will provide a return to our shareholders.
We have not paid or declared any dividends on our common stock and currently intend to retain any earnings to fund our working capital needs, reduce debt and fund growth opportunities. Any future dividends will be at the discretion of our board of directors after taking into account various factors it deems relevant, including our financial condition and performance, cash needs, income tax consequences and restrictions imposed by the Texas Business Organizations Code and other applicable laws and by our Revolving CreditTerm Loan, ABL Facility, and Senior Notes. Our debt arrangements include provisions that generally prohibit us from paying dividends on our capital stock, including our common stock.

27



We may issue preferred stock whose terms could adversely affect the voting power or value of our common stock.
Our articles of incorporation authorize us to issue, without the approval of our shareholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our common stock respecting dividends and distributions, as our board of directors may determine.determine; however, our issuance of preferred stock is subject to the limitations imposed on us by our ABL Facility and Senior Notes. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of the common stock.
Provisions in our organizational documents could delay or prevent a change in control of our company even if that change would be beneficial to our shareholders.
The existence of some provisions in our organizational documents could delay or prevent a change in control of our company even if that change would be beneficial to our shareholders. Our articles of incorporation and bylaws contain provisions that may make acquiring control of our company difficult, including:
provisions regulating the ability of our shareholders to nominate candidates for election as directors or to bring matters for action at annual meetings of our shareholders;
limitations on the ability of our shareholders to call a special meeting and act by written consent;
provisions dividing our board of directors into three classes elected for staggered terms; and
the authorization given to our board of directors to issue and set the terms of preferred stock.

Company Overview

Pioneer Energy Services Corp. provides land-based drilling services and production services to a diverse group of independent and large oil and gas exploration and production companies in the United States and internationally in Colombia. We also provide two of our services (coiled tubing and wireline services) offshore in the Gulf of Mexico. Drilling services and production services are fundamental to establishing and maintaining the flow of oil and natural gas throughout the productive life of a well and enable us to meet multiple needs of our clients.
well.
Business Segments
Our business is comprised of two business lines Drilling Services and Production Services. We conduct our operations through two operating segments:report our Drilling Services Segmentbusiness as two reportable segments: (i) Domestic Drilling and (ii) International Drilling. We report our Production Services Segment.business as three reportable segments: (i) Well Servicing, (ii) Wireline Services, and (iii) Coiled Tubing Services. Financial information about our operating segments is included in Note 10,11, Segment Information, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Drilling Services Segment—Services—From 1999 to 2011, we significantly expanded our fleet through acquisitions and the construction of new drilling rigs. As our industry changed with the evolution of shale drilling, we began a transformation process in 2011, by selectively disposing of our older, less capable rigs, while we continued to invest in our rig building program to construct more technologically advanced, pad-optimal rigs to meet the changing needs of our clients.
As of December 31, 2016, our Our current drilling rig fleet is 100% pad-capable. We offerpad-capable and offers the latest advancements in pad drilling with our fleet ofdrilling. We have 16 AC rigs in the US and eight SCR rigs in Colombia, all of which have 1,500 horsepower or greater drawworks. The removal of older, less capable rigs from our fleet and the recent investments in the construction of new drilling rigs has transformed our fleet intoWe provide a highly capable, pad optimal fleet focused on the horizontal drilling market. We believe this positions us to compete well, grow our presence in the significant shale basins in the US, and improve profitability as the recovery of our industry continues.

32




In addition to our drilling rigs, we providecomprehensive service offering which includes the drilling rig, crews, supplies and most of the ancillary equipment needed to operate our drilling rigs. We obtainrigs which are deployed through our contracts for drilling oil and natural gas wells either through competitive bidding or through direct negotiations with existing or potential clients. Our drilling contracts generally provide for compensation on a daywork basis, and sometimes on a turnkey basis. Contract terms generally depend on the complexity and risk of operations, the on-site drilling conditions, the type of equipment used, and the anticipated duration of the work to be performed. The drilling rigsdivision offices in our fleet are currently assigned to the following divisions:regions:
Drilling Division Rig Count
South TexasDomestic drilling: 1
Marcellus/Utica6
West TexasPermian Basin and Eagle Ford 78
North DakotaBakken 2
Appalachia6
ColombiaInternational drilling 8
  24
Production Services Segment—Services— Our In 2008, we acquired two production services companies which significantly expanded our service offerings to include well servicing and wireline services. At the end of 2011, we acquired a coiled tubing services business to further expand our production services offerings. Since the acquisitions of these businesses, we continued to invest in their organic growth and significantly expanded all our production services fleets. However, we temporarily suspended organic growth of our production services fleets during the recent downturn, and continue to selectively update our fleets.
Our Production Services Segment providessegments provide a range of well, wireline and coiled tubing services to a diverse group of exploration and production companies, with our operations concentrated in the major United Statesdomestic onshore oil and gas producing regions in the Mid-Continent and Rocky Mountain states and in the Gulf Coast, both onshore and offshore. The primary production services we offer are the following:
Well Servicing. A range of services are required in order to establish production in newly-drilled wells and to maintain production over the useful lives of active wells. We use our well servicing rig fleet to provide these necessary services, including the completion of newly-drilled wells, maintenance and workover of active wells, and plugging and abandonment of wells at the end of their useful lives. As of December 31, 2016, we have a fleet of 114 rigs with 550 horsepower and 11 rigs with 600 horsepower with operations in 10 locations, mostly in the Gulf Coast states, as well as in Arkansas and North Dakota.
Wireline Services. Oil and gas exploration and production companies require wireline services to better understand the reservoirs they are drilling or producing, and use logging services to accurately characterize reservoir rocks and fluids. To complete a cased-hole well, the production casing must be perforated to establish a flow path between the reservoir and the wellbore. We use our fleet of wireline units to provide these important logging and perforating services in addition to a range of other mechanical services that are needed in order to place equipment in or retrieve equipment or debris from the wellbore, install bridge plugs and control pressure. As of December 31, 2016, we have a fleet of 114 wireline units in 17 operating locations in the Gulf Coast, Mid-Continent and Rocky Mountain states.
Coiled Tubing Services. Coiled tubing is also an important element of the well servicing industry that allows operators to continue production during service operations on a well under pressure without shutting in the well, thereby reducing the risk of formation damage. Coiled tubing services involve the use of a continuous metal pipe spooled on a large reel for oil and natural gas well applications, such as wellbore clean-outs, nitrogen jet lifts, through-tubing fishing, formation stimulation utilizing acid, chemical treatments and fracturing. Coiled tubing is also used for a number of horizontal well applications such as milling temporary plugs between frac stages. As of December 31, 2016,2018, the fleet count for each of our coiled tubingproduction services business consists of 12 onshore and five offshore coiled tubing units whichsegments are deployed through three locations in Texas and Louisiana.as follows:

Market Conditions in Our Industry
Industry Overview — Demand for oilfield services offered by our industry is a function of our clients’ willingness to make operating expenditures and capital expenditures to explore for, develop and produce hydrocarbons, which is primarily driven by current and expected oil and natural gas prices.
Our business is influenced substantially by both operating and capital expenditures by exploration and production companies. Exploration and productioncompanies’ spending that is generally categorized as either a capital expenditure or an operating expenditure. Capital expenditures by exploration and production companies for the drilling and completion of exploratory wells or newand development wells in proven areas are more directly influenced by current and expected oil and natural gas prices and generally reflect the volatility of commodity prices. In contrast, operating expenditures by exploration and production companies for the maintenance of existing wells, for which a range of production services are required in order to maintain production, are relatively more stable and predictable.
Drilling and production services have historically trended similarly in response to fluctuations in commodity prices. However, because exploration and production companies often adjust their budgets for exploratoryexploration and development drilling first in response to a shiftchange in commodity prices, the demand for drilling services is generally impacted first and to a greater extent than the demand for production services which is more dependent on ongoing expenditures that are necessary to

32




maintain production. Additionally, within the range of production services businesses, those that derive more revenue from production related activity, as opposed to completion of a new well,wells, tend to be less affected by fluctuations in commodity prices and temporary reductions in industry activity.
However, in a severe downturn that is prolonged, both operating and capital expenditures are significantly reduced, and the demand for all our service offerings is significantly impacted. After a prolonged downturn, among the production services, the demand for completion-oriented services generally improves first, as exploration and production companies begin to complete wells that were previously drilled but not completed during the downturn, and to complete newly drilled wells as the demand for drilling services improves during recovery.
From time to time, temporary regional slowdowns or constraints occur in our industry due to a variety of factors, including, among others, infrastructure or takeaway capacity limitations, labor shortages, increased regulatory or environmental pressures, or an influx of competitors in a particular region. Any of these factors can influence the profitability of operations in the affected region. However, term contract coverage for our drilling services business and the mobility of all our equipment between regions limits our exposure to the impact of regional constraints and fluctuations in demand.
Technological advancements and trends in our industry also affect the demand for certain types of equipment, and can affect the overall demand for the services our industry provides. Enhanced directional and horizontal drilling techniques have allowed exploration and production operators to drill increasingly longer lateral wellbores which enable higher hydrocarbon production per well, and reduce the overall number of wells needed to achieve the desired production. This trend toward longer lateral wellbores also increases demand for the more specialized equipment, such as high-spec drilling rigs, higher horsepower well servicing rigs equipped with taller masts, larger diameter coiled tubing units, and other higher power ancillary equipment, which is needed in order to drill, complete and provide services to the full length of the wellbore. Our domestic drilling and production services fleets are highly capable and designed for operation in today’s long lateral, pad-oriented environment.
For additional information concerning the potential effects of the volatility in oil and gas prices and the effects of technological advancements andother industry trends, in our industry, see Item 1A – “Risk Factors” in Part I of this Annual Report on Form 10-K.
Market Conditions — SinceOur industry experienced a severe down cycle from late 2014 through 2016, during which WTI oil prices have declined significantly resultingdipped below $30 per barrel in early 2016. A modest recovery in commodity prices began in the latter half of 2016 with WTI oil prices steadily increasing from just under $50 per barrel at the end of June 2016 to approximately $60 per barrel at the end of 2017. In 2018, WTI oil prices continued to increase to a downturnhigh of $75 per barrel in our industry, affecting both drillingOctober, but then decreased to $45 per barrel at the end of 2018, and production services. averaged approximately $50 per barrel during January 2019.

33




The trends in spot prices of WTI crude oil and Henry Hub natural gas, and the resulting trends in domestic land rig counts (per Baker Hughes) and domestic well servicing rig counts (per Guiberson/Association of Energy Service Companies) over the last three years are illustrated in the graphs below.
a3yrspotpricesandrigcountv2.jpg

33




At the end of 2016, the spot prices of WTI crude oil and Henry Hub natural gas were down by 50% and 44%, respectively, as compared to the peak 2014 prices. During this same period, the horizontal and vertical drilling rig counts in the United States dropped by 62% and 83%, respectively, while the domestic well servicing rig count decreased by 46%. Despite the modest recovery in commodity prices during recent months, commodity prices have remained low as compared to the price levels in 2014 and continue to depress activity and pricing for all our service offerings.
The trends in commodity pricing and domestic rig counts over the last 12 months are illustrated below:
a1yrspotpricesandrigcountv3.jpg
Our well servicingWe began 2017 with utilization of our domestic fleet at 81% and coiled tubingfour rigs working in Colombia. By mid- 2018, utilization ratesof our domestic fleet increased to 100%, and seven of our eight international rigs are currently earning revenues under term contracts. In July 2018, we entered into a three-year term contract for the quarter ended December 31, 2016 were 40% and 21%, respectively, based on total fleet count, andconstruction of a new 1,500 horsepower, AC pad-optimal rig, which we are currently actively marketing approximately 65% of our wireline fleet. These utilization rates are roughly flat with those of the prior fiscal quarter dueexpect to recent stabilitydeploy in commodity prices, while the number of wireline jobs completed during the quarter ended December 31, 2016 increased by 10%, as comparedearly 2019 to the prior fiscal quarter.Permian Basin.
In drilling, all rig classes were severely impacted by the industry downturn. As a result, term contracts for 19 of our drilling rigs were terminated early, including three that were terminated in early 2016. However, with the moderate improvement in commodity prices in late 2016, several of our AC rigs were subsequently placed on new spot contracts and as of December 31, 2016, the current utilization2018, 23 of our AC rig fleet is 81%. Of the eight rigs in Colombia, four of the24 drilling rigs in Colombia are earning revenues, three19 of which are under term contracts. We are actively marketing our idle drilling rigs in Colombia to various operators and we are evaluating other options, including the possibility of the sale of some or all of our assets in Colombia.
As of December 31, 2016, 17 of our drilling rigs are currently under contract,contracts, which if not canceled or renewed prior to the end of their terms, will expire as follows:

Our international drilling contracts are cancelable by our clients significantlywithout penalty, although the contracts require 15 to 30 days notice and payment for demobilization services. We are actively marketing our idle rig in Colombia, and we also continue to evaluate the possibility of selling some or all of our assets in Colombia.
During the quarter ended December 31, 2018, our well servicing rig hours were steady with the previous quarter, while the number of wireline jobs completed and revenue days for our coiled tubing services decreased by 10% and 4%, respectively,

34




as compared to the third quarter of 2018. Average revenue rates for our well servicing and coiled tubing services provided during this same period increased by 3% and 6% (on a per hour and per day basis, respectively), while average revenues per job for our wireline services decreased by 6%. The decrease in wireline services revenue was primarily due to reduced both theircompletion activity which has been a significant portion of our wireline segment’s overall activity. The modest increase in coiled tubing revenues is primarily attributable to an increase in the proportion of work performed by our large-diameter coiled tubing units, which generally earn higher revenue rates as compared to smaller diameter coiled tubing units, while the modest increase in well servicing revenues corresponds with improved pricing, partially due to an increase in the completion work performed by our well servicing business.
The level of exploration and production activity within a region can fluctuate due to a variety of factors which may directly or indirectly impact our operations in the region. Despite the recovery of demand experienced in onshore markets, offshore activity remained depressed, and as a result, we exited the offshore wireline and coiled tubing market in the second quarter of 2018. In the Permian Basin, limited takeaway capacity has led to price discounts on crude oil that could continue to impact activity and near term growth in the region; however, our exposure to any decreases in activity is limited because we have term contract coverage for six of our seven drilling rigs currently operating and capital expenditures during 2015 and 2016, but increases are expected for 2017. in this region.
Although we expect a highly competitive environment in 2017, we expect the recent modest recovery in commodity prices, if it continues, to further increase industry activity and pricing levels andcontinue, we believe our high-quality equipment and services areand our excellent safety record make us well positioned to compete.

Liquidity and Capital Resources
Sources of Capital Resources
Our principal liquidity requirements are for working capital needs, debt service and capital expenditures. Our principal sources of liquidity currently consist ofof:
total cash and cash equivalents (which equaled $10.2($54.6 million as of December 31, 2016), 2018);
cash generated from operations ($39.7 million during the year ended December 31, 2018);
proceeds from sales of assets ($5.9 million during the year ended December 31, 2018); and
the availability under our asset-based lending facility ($49.0 million as of December 31, 2018).
Senior Secured Term Loan — Our senior secured term loan (the “Term Loan”) entered into on November 8, 2017 provided for one drawing in the amount of $175 million, net of a 2% original issue discount. Proceeds from the issuance of the Term Loan were used to repay the entire outstanding balance under our previous credit facility, plus fees and accrued and unpaid interest, as well as the fees and expenses associated with entering into the Term Loan and ABL Facility, which is further described below. The remainder of the proceeds are available to be used for other general corporate purposes. The Term Loan is set to mature on November 8, 2022, or earlier, subject to certain non-strategic assetscircumstances as described in the agreement, and including an earlier maturity date if the unused portionoutstanding balance of ourthe Senior Notes exceeds $15.0 million on December 14, 2021, at which time the Term Loan would then mature. The Term Loan contains certain covenants which are described in more detail in the Debt Compliance Requirements section below.
Asset-based Lending Facility — In addition to entering into the Term Loan, on November 8, 2017, we also entered into a senior secured revolving asset-based credit facility (the “Revolving Credit“ABL Facility”). providing for borrowings in the aggregate principal amount of up to $75 million, subject to a borrowing base and including a $30 million sub-limit for letters of credit. The ABL Facility bears interest, at our option, at the LIBOR rate or the base rate as defined in the ABL Facility, plus an applicable margin ranging from 1.75% to 3.25%, based on average availability on the ABL Facility. The ABL Facility is generally set to mature 90 days prior to the maturity of the Term Loan, subject to certain circumstances, including the future repayment, extinguishment or refinancing of our Term Loan and/or Senior Notes prior to their respective maturity dates. We have not drawn upon the ABL Facility to date. As of December 31, 2018, we had $9.7 million in committed letters of credit, which, after borrowing base limitations, resulted in borrowing availability of $49.0 million. Borrowings available under the ABL Facility are available for general corporate purposes, and there are no limitations on our ability to access the borrowing capacity provided there is no default and compliance with the covenants under the ABL Facility is maintained. Additional information regarding these covenants is provided in the Debt Compliance Requirements section below.
Shelf Registration Statement — In the future, we may also consider equity and/or debt offerings, as appropriate, to meet our liquidity needs. On May 2015,22, 2018, we filed a registration statement that permits us to sell equity or debt in one or more offerings up to a total dollar amount of $300 million. In December 2016, we sold 12,075,000 shares of common stock in a public offering, which resulted in proceeds of approximately $65.4 million, net of underwriting discounts and offering expenses, under the shelf registration statement. As of December 31, 2016, $234.62018, the entire $300.0 million under the shelf registration statement is available for equity or debt offerings, subject to the limitations imposed by our Revolving CreditTerm Loan, ABL Facility and Senior Notes, as well as our Restated Articles of Incorporation which currently limits our issuance of common stock to 100 million shares. In the future, we may consider equity and/or debt offerings, as appropriate, to meet our liquidity needs.
In 2014, we issued $300 million of unregistered senior notes with a coupon interest rate of 6.125% that are due in 2022 (the “Senior Notes”). In order to reduce our overall interest expense and lengthen the overall maturity of our senior indebtedness, during 2014, we redeemed all of our then outstanding $425 million of unregistered senior notes with a coupon interest rate of 9.875% that were issued in 2010 and 2011 and were set to mature in 2018, funded primarily by proceeds from the issuance of Senior Notes in 2014 and additional borrowings under our Revolving Credit Facility, as well as some cash on hand.Notes.
Our Revolving Credit Facility, as most recently amended on June 30, 2016, provides for a senior secured revolving credit facility, with sub-limits for letters of credit and swing-line loans, of up to a current aggregate commitment amount of $150 million, subject to availability under a borrowing base comprised of certain eligible cash, certain eligible receivables, certain eligible inventory, and certain eligible equipment of ours and certain of our subsidiaries, all of which matures in March 2019.
In accordance with the Revolving Credit Facility terms, all of the net proceeds from our public equity offering in December 2016 were applied to reduce the outstanding borrowing balance, and the total commitment amount available was reduced from $175 million to $150 million. As of January 31, 2017, we had $49.7 million outstanding under our Revolving Credit Facility and $11.8 million in committed letters of credit, which resulted in borrowing availability of $88.5 million under our Revolving Credit Facility. Borrowings under the Revolving Credit Facility are available for selective acquisitions, working capital and other general corporate purposes. There are no limitations on our ability to access the borrowing capacity provided there is no default, all representations and warranties are true and correct, and compliance with financial covenants under the Revolving Credit Facility is maintained. Additional information regarding these covenants is provided in the Debt Requirements section below.

At December 31, 2016, we were in compliance with our financial covenants under the Revolving Credit Facility. However, continued compliance with our covenants is largely dependent on our ability to generate sufficient levels of EBITDA, as defined in the Revolving Credit Facility, and/or reduce our debt levels. If we expect our future operating results to decline to a level that indicates we may become unable to comply with the financial covenants in the Revolving Credit Facility, we may seek to amend such provisions to remain in compliance or we may pursue other capital sources, such as equity or other debt transactions. Although we believe that our bank lenders are well-secured under the terms of our Revolving Credit Facility, there is no assurance that the bank lenders will waive or amend our financial covenants under the Revolving Credit Facility.



We currently expect that cash and cash equivalents, cash generated from operations, proceeds from sales of certain non-strategic assets, and available borrowings under our Revolving CreditABL Facility are adequate to cover our liquidity requirements for at least the next 12 months.

Uses of Capital Resources
Our principal liquidity requirements are currently for:
capital expenditures;
debt service; and
working capital needs.
Our operations have historically generated cash flows sufficient to meet our requirements for debt service and normal capital expenditures. However, our working capital requirements generally increase during periods when rig construction projects are in progress or during periods of expansion in our production services business, at which times we have been more likely to access capital through equity or debt financing. Additionally, our working capital needs may increase in periods of increasing activity following a sustained period of low activity. During periods of sustained low activity and pricing, we may also access additional capital through the use of available funds under our ABL Facility.

Capital Expenditures — For the yearsyear ended December 31, 20162018 and 2015,2017, our primary uses of capital resources were for property and equipment additions, which consisted of the following (amounts in thousands):

In 2016,2017 and 2018, we lowered our capital expenditures by 77% in response to the downturn, limitinglimited our capital spending to primarily routine expenditures and select asset acquisitions to optimize our fleets. Routine and discretionary capital expenditures during 2018 primarily related to routine expenditures to maintain our fleets, as well as the purchase of new support equipment and deferring discretionaryvehicle fleet upgrades and additions except those that we committed to in 2014 before the market slowdown.all domestic business segments. Capital expenditures during 2015 primarily related to our five drilling rigs which began construction during 2014for fleet additions in 2018 included the purchase of a coiled tubing unit, the remaining installments on another coiled tubing and were completed in 2015, and included $3.0 million of interest costs capitalized during the construction period. Additionally, during 2015, we acquired eightthree wireline units and nine well servicing rigs thatwhich were ordered in 2014. In late 2016,2017, and the construction of one new drilling rig, which we committedexpect to tradedeploy in early 2019. Capital expenditures for fleet additions in 2017 included the exchange of 20 of our older 550 horsepower well servicing rigs for 20 new-model rigs, to be delivered in the first quarterpurchase of 2017 and we committed to purchase four new wireline units, and deposits on one coiled tubing unit and three wireline units which were delivered in 2018. Routine expenditures in 2017 primarily included refurbishments and start-up costs to be delivered beginningredeploy assets that had been idle, including two drilling rigs in March 2017.Colombia.
Currently, we expect to spend approximately $45$55 million to $60 million on capital expenditures during 2017,2019, which we expect will be allocated includes approximately 40% $7 millionfor our Drilling Services Segment and approximately 60% for our Production Services Segment. Our total planned capital expenditures include approximately $20 million for fleet upgrades and additions, includingfinal payments on the upgradeconstruction of one domesticthe new-build drilling rig that is expected to begin operations in the exchange of 20 well servicing rigsfirst quarter, and the addition of four new wireline units, and other routine capital expenditures.previous commitments on high-pressure pump packages for coiled tubing completion operations. Actual capital expenditures may vary depending on the climate of our industry and any resulting increase or decrease in activity levels, the timing of commitments and payments, and the level of rig build and other expansion opportunities that meet our strategic and return on capital employed criteria. We expect to fund the capital expenditures in 20172019 from operating cash flow in excess of our working capital requirements, although proceeds from sales of certain non-strategic assets, remaining proceeds from our Term Loan issuance, and fromavailable borrowings under our Revolving CreditABL Facility are also available, if necessary.

Working Capital
Our working capital was $48.0$110.3 million at December 31, 2016,2018, compared to $45.2$130.6 million at December 31, 2015.2017. Our current ratio, which we calculate by dividing current assets by current liabilities, was 1.72.1 at December 31, 2016,2018, as compared to 1.62.5 at December 31, 2015.
Our operations have historically generated cash flows sufficient to meet our requirements for debt service and normal capital expenditures. However, our working capital requirements generally increase during periods when rig construction projects are in progress, during periods of expansion in our production services business, or when higher percentages of our drilling contracts are turnkey contracts, at which times we have been more likely to access capital through equity or debt financing. During periods of sustained low activity and pricing, we may access additional capital through the use of available funds under our Revolving Credit Facility.

Cash and cash equivalentsThe change in our cash and cash equivalents during the year ended December 31, 20162018 is primarily a resultdue to $67.1 million of net cash used in investing activities of $24.8 million which was mostly offset by cash provided by financing activities of $15.7 million. Our net cash used in investing activities was primarily for the purchasespurchase of property and equipment, of $32.4 million and partially offset by $7.6$39.7 million of cash from operating activities, $5.9 million of proceeds from the salessale of assets. Our net cashproperty and equipment, and $1.1 million of proceeds from insurance recoveries. Cash provided by financing activities isoperations during 2018 was primarily due tofrom the recent increase in activity.
Restricted cashOur restricted cash balance reflects the portion of net proceeds from borrowings under the Revolving Credit Facilityissuance of $16.4 million, netour Term Loan, which are currently held in a restricted account until the completion of repayments. In December, we issued equity which resulted in net proceedscertain administrative tasks related to providing access rights to certain of $65.4 million, whichour real property. During 2018, a portion of these restricted funds were applied to reduce the level of debt outstanding under the Revolving Credit Facility.released and made available for general corporate use.
Trade and Unbilled receivablesThe net decreaseincrease in our total trade and unbilled receivables from December 31, 2015 to 2016during 2018 is primarily due to the result of the decrease12% increase in consolidatedour revenues of $33.0 million, or 32%, forduring the quarter ended December 31, 20162018, as compared to the quarter ended December 31, 2015.2017, as well as the timing of billing and collection cycles for long-term drilling contracts in Colombia. Our domestic trade receivables generally turn over within 9060 days, and our Colombian trade receivables generally turn over within 120 days.
Insurance recoveries and Insurance claims and settlements — The increase during 2018 in both our insurance recoveries receivables from December 31, 2015 to 2016 is attributable to an insurance claim receivable of $3.3 million, which was received in January 2017,and our accrued liability for a drilling rig that was damaged during the second quarter of 2016. The decrease in our insurance claims and settlements from December 31, 2015 to 2016 is primarily due to a decrease in our insurance company’s reserve forvery high costs incurred on one significant workers’ compensation claimsclaim in excess of our deductibles.$500,000 deductible, which are covered by our workers compensation insurance policy.
Other receivables — The increase in other receivables from December 31, 2015 to 2016during 2018 is primarily due to a $6.3 million receivable arising from the sale of two drilling rigsan increase in December 2016, for which we received the proceeds in January 2017, which was partly offset by a decrease in netrecoverable income tax receivables attributable to the increase in activity for our Colombian operations.
Asinternational operations, partially offset by the collection of December 31, 2016, our consolidated balance sheet reflects $15.1 milliona short-term note receivable from the sales of assets held for sale, which primarily represents the fair value of six domestictwo mechanical and SCR drilling rigs and drilling equipment, 13 wireline units, 20 older well servicing rigs that will be traded in for 20 new-model rigs inwere sold during the firstthird quarter of 2017,2017.
Inventory — The increase in inventory during 2018 is primarily associated with the increase in activity for our international drilling operations and certainan increase in large diameter pipe inventory for our coiled tubing equipment. Our assets held for sale as of December 31, 2015 primarily consisted of four domestic drilling rigs.operations.
Our accounts payable generally turn over within 90 days. Excluding the effect of employee related costs, which do not impact accounts payable, operating costs were roughly flat for the quarter ended December 31, 2016 as compared to the quarter ended December 31, 2015. However, our accounts payable increased from December 31, 2015 to 2016

37




as a result
Assets held for sale — As of increased costs associated withDecember 31, 2018, our consolidated balance sheet reflects assets held for sale of $3.6 million, which primarily represents the recentfair value of two domestic SCR drilling rigs, spare drilling equipment that would support these rigs and three coiled tubing units. As of December 31, 2017, our consolidated balance sheet reflects assets held for sale of $6.6 million, which primarily represents the fair value of three domestic SCR drilling rigs, one domestic mechanical drilling rig, spare drilling equipment that would support these rigs, two wireline units, one coiled tubing unit and other spare equipment. For additional information, see Note 3, Property and Equipment of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Prepaid expenses and other current assetsThe increase in activity, including expendituresprepaid expenses and other current assets during 2018 is primarily due to an increase in software subscription renewals and partially due to the increase in international deferred mobilization costs associated with the deployment of threefive international rigs during 2018. For additional information about rig mobilization revenue and one domestic rig that mobilized in the fourth quarter.
cost recognition, see Note 2, The decrease in deferred revenuesRevenue from December 31, 2015 to 2016 is primarily related to deferred revenue for early termination payments on drilling contracts that ended during 2016. Revenues derived from rigs placed on standby or from the early termination of term drilling contracts are deferred and recognized as the amounts become fixed or determinable, over the remainderContracts with Customers of the original term or when the rig is sold. (SeeNotes to Consolidated Financial Statements, included in Part II, Item 8, Critical Accounting PoliciesFinancial Statements and Estimates Supplementary Datasection for more detail.) All, of the contracts that were early terminated have expired as of December 31, 2016 and all the associated revenue from the early terminations has been recognized. Deferred revenues as of December 31, 2016 relate to payments received for the mobilization of our domestic and Colombia drilling rigs, which are deferred and recognizedthis Annual Report on a straight line basisForm 10-K.

Operating leases — Our operating leases consist of lease agreements for office space, operating facilities, equipmentfield personnel housing, and personal property.office equipment.
Incentive compensation — Incentive compensation is payable to our employees, generally contingent upon their continued employment through the date of each respective award’s payout. A portion of our long-term incentive compensation is performance-based and therefore the final amount will be determined based on our actual performance relative to a pre-determined peer group over the performance period.

Debt Requirements
Debt Compliance Requirements — The Revolving Credit Facility contains customary mandatory prepayments from the proceedsfollowing is a summary of certain asset dispositions or equity or debt issuances, which are applied to reduce outstanding revolving and swing-line loans and to cash-collateralize letter of credit exposure, and in certain cases, also reduce the commitment amount available. There are no limitations on our ability to access the borrowing capacity provided there is no default, all representations and warranties are true and correct, and compliance with financial covenants under the Revolving Credit Facility is maintained.
At December 31, 2016, we were in compliance with our financial covenants under the Revolving Credit Facility. Our senior consolidated leverage ratio was 3.1 to 1.0 and our interest coverage ratio was 0.7 to 1.0. However, continued compliance with our covenants is largely dependent on our ability to generate sufficient levels of EBITDA, as defined in the Revolving Credit Facility, and/or reduce our debt levels. If we expect our future operating results to decline to a level that indicates we may become unable to comply with the financialcompliance requirements including covenants, in the Revolving Credit Facility, we may seek to amend such provisions to remain in compliance or we may pursue other capital sources, such as equity or other debt transactions. Although we believe that our bank lenders are well-secured under the terms of our Revolving Credit Facility, there is no assurance that the bank lenders will waive or amend our financial covenants under the Revolving Credit Facility.
The financial covenants contained in our Revolving Credit Facility include the following,restrictions and guarantees, all of which are described in more detail in Note 3,4, Debt, of the Notes to Consolidatedand Note 14, Guarantor/Non-Guarantor Condensed Consolidating Financial Statements included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K:
A maximum senior consolidated leverage ratio, calculated as senior consolidated debt at the period end, which excludes unsecured and subordinated debt, divided by EBITDA for the trailing twelve month period at each quarter end, as defined in the Revolving Credit Facility.
A minimum interest coverage ratio, calculated as EBITDA for the trailing twelve month period at each quarter end, as defined in the Revolving Credit Facility, divided by interest expense for the same period.
A minimum EBITDA requirement, for the periods indicated, as defined in the Revolving Credit Facility.
The Revolving Credit Facility also restricts capital expenditures, as further described in Note 3, Debt, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
The Revolving Credit FacilityTerm Loan contains a financial covenant requiring the ratio of (i) the net orderly liquidation value of our fixed assets (based on appraisals obtained as required by our lenders), on a consolidated basis, in which the lenders under the Term Loan maintain a first priority security interest, plus proceeds of asset dispositions not required to be used to effect a prepayment of the Term Loan to (ii) the outstanding principal amount of the Term Loan, to be at least equal to 1.50 to 1.00 as of any June 30 or December 31 of any calendar year through maturity. As of December 31, 2018, the asset coverage ratio, as calculated under the Term Loan, was 2.36 to 1.00.
The Term Loan contains customary mandatory prepayments from the proceeds of certain transactions including certain asset dispositions and debt issuances, and has additional restrictive covenantscustomary restrictions that among other things, limit our ability to:
incur additional debt or make prepayments of existing debt;
create liens on or dispose of our assets;
pay dividends on stock or repurchase stock;
to enter into acquisitions, mergers, consolidations, sale leaseback transactions, or hedging contracts;
make other restricted investments;
conduct transactions with affiliates; and
limits our use of the net proceeds of any offering of our equity securities to the repayment of debt outstanding under the Revolving Credit Facility.

The ABL Facility also contains customary restrictive covenants which, subject to certain exceptions, limit, among other things, our ability to enter into certain transactions.

Drilling Services Segment margin represents contract drilling revenues less contract drilling operating costs. Production Services Segment margin represents production services revenue less production services operating costs. Drilling Services Segment margin and Production Services Segment margin are non-GAAP financial measures which we consider to be important supplemental measures of operating performance. Our management uses these measures to facilitate period-to-period comparisons in operating performance of our reportable segments. We believe that Drilling Services Segment margin and Production Services Segment margin are useful to investors and analysts because they provide a means to evaluate the operating performance of the segments on an ongoing basis using criteria that are used by our internal decision makers. Additionally, the use of these measures highlights operating trends and aids in analytical comparisons. Drilling Services Segment margin and Production Services Segment margin as presented may not be comparable to other similarly titled measures reported by other companies.
(1)    Adjusted EBITDA represents income (loss) before interest expense, income tax (expense) benefit, depreciation and amortization, impairment, and loss on extinguishment of debt and impairments.debt. Adjusted EBITDA is a non-GAAP measure that our management uses to facilitate period-to-period comparisons of our core operating performance and to evaluate our long-term financial performance against that of our peers. We believe that this measure is useful to investors and analysts in allowing for greater transparency of our core operating performance and makes it easier to compare our results with those of other companies within our industry. Adjusted EBITDA should not be considered (a) in isolation of, or as a substitute for, net income (loss), (b) as an indication of cash flows from operating activities or (c) as a measure of

BothConsolidated gross marginOur consolidated gross margin increased by $44.6 million, or 39%, during 2018 as compared to 2017, which reflects increased revenue rates for all of our Drilling Servicesservice offerings, and Production Services Segments experienced a significant declineincreased activity, particularly for our domestic and international drilling services. All of our business segments contributed to the increase in activity duringmargin. Of the $44.6 million increase in consolidated gross margin for the year ended December 31, 2016,2018, as compared to 2015, duethe corresponding period in 2017, 52% is attributable to our drilling services segments, with improved demand and higher dayrates for both our domestic and international drilling services, while the current downturnincrease in our industry. production services segments was led by increased demand for our wireline services, driven by increased completion activity, and to a lesser extent, well servicing activity and pricing.
DrillingServicesOur combined margin decreaseddrilling services revenues increased by $59.2 million, or 35%, during 2016,2018 as compared to 2015, primarily as a result of decreased activity and pricing pressure for all our service offerings.
In response to the downturn in our industry, we took several actions to reduce costs and better scale our business to the reduced revenues. We reduced our total headcount by over 50% since the beginning of 2015. We reduced wage rates for our operations personnel, reduced incentive compensation and eliminated certain employment benefits. We closed ten field offices since the beginning of 2015 to reduce overhead and reduce associated lease payments, amended our revolving credit facility, and sold 35 drilling rigs and other drilling equipment for aggregate net proceeds of $65.5 million. As of December 31, 2016, we have six additional domestic mechanical and SCR drilling rigs held for sale, along with other drilling equipment, 13 wireline units, 20 older well servicing rigs that will be traded in for 20 new-model rigs in the first quarter of 2017, and certain coiled tubing equipment.
Our Drilling Services Segment’s revenues decreased by $130.1 million, or 52%, during 2016, as compared to 2015, while operating costs decreasedincreased by $71.0$35.9 million, or 49%31%. The decreasesincreases in our Drilling Services Segment’sdrilling services revenues and operating costs primarily resulted from a 46%17% increase in revenue days during 2018 as compared to 2017, primarily attributable to a 67% increase in utilization of our international drilling fleet.

Our domestic drilling fleet utilization has been fully utilized since mid-2017, allowing us to achieve the higher margins of a fully utilized fleet. Our domestic drilling average revenues per day during 2018 increased as compared to 2017,

41




primarily due to increasing dayrates on term contracts for eight rigs, partially offset by reduced dayrates for four rigs that were re-priced from historically high pre-downturn rates in 2018. Our average domestic drilling operating costs per day for the year ended December 31, 2018 decreased from the corresponding period in 2017, primarily due to additional costs incurred during the first half of 2017 to deploy previously idle rigs under new contracts and to move one rig to a new region in mid-2017 under a new term contract.
Our international drilling fleet utilization has steadily improved since the beginning of 2017, with seven of eight rigs utilized at December 31, 2018, versus four rigs utilized at the beginning of 2017. This utilization improvement has been the primary reason for the increases in our international drilling average revenues, operating costs and margin per day during 2018, as compared to 2017. Our international drilling average margin per day also increased during 2018 as compared to 2017, in part due to several drilling rigs re-pricing at higher dayrates during 2018 and additional costs incurred during 2017 to redeploy drilling rigs under new term contracts.
Production ServicesOur revenues from production services increased by $84.4 million, or 31%, during 2018 as compared to 2017, while operating costs increased by $63.2 million, or 29%, respectively. The increases in revenues and operating costs in our production services segments are a result of the increased demand for our services, particularly those that perform completion-related activities.

Increases in production services revenues and operating costs were led by our wireline services business segment, which experienced a significant increase in completion-related activity as wells that were drilled but not completed during the downturn created higher demand for completion services. Although the number of wireline jobs decreased slightly, average revenue per job increased by 34% during 2018, as compared to 2017, which is largely due to a higher percentage of the work performed being attributable to completion-related jobs which earn higher revenue rates, but also incur higher costs for the job materials consumed on these types of jobs.
Our well servicing business segment also experienced an increase in demand during 2018 as utilization increased to 49% during 2018 from 43% during 2017. This utilization improvement represents a 14% increase in well servicing rig hours, while average revenue per hour also increased by 6%.
During 2018, our coiled tubing services business segment experienced an increase in demand for services provided using our larger diameter coiled tubing units. Despite a slight decrease in revenue days during 2018, as compared to 2017, average revenue per day increased 51% primarily due to a larger proportion of the significant reductionwork performed with larger diameter coiled tubing units which typically earn higher revenue rates as compared to smaller diameter coiled tubing units, partially resulting from the addition of one new large diameter coiled tubing unit which we placed in demandservice in July 2018. The expansion of our industry.coiled tubing operations into a new market in late 2017 and the closure of under-performing locations in 2018 also contributed to the improvement in gross margin, as compared to 2017.
Depreciation expense — Our depreciation expense decreased by $5.2 million during 2018 as compared to 2017. The decrease is almost entirely attributable to our domestic drilling operations. With our reduced domestic rig fleet size and decreased

42




utilization during 2015 and 2016, we had sufficient drill pipe and other spare equipment on hand which allowed us to defer additional capital spending on these items during recent years.
ImpairmentDuring the years ended December 31, 2018 and 2017, we recognized impairment charges of $4.4 million and $1.9 million, respectively, to reduce the carrying values of certain assets which were classified as held for sale, to their estimated fair values based on expected sale prices. For more detail, see Note 3, Property and Equipment, of the Notes to Consolidated Financial Statements, included in Part II, Item 8 Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Interest expense — Our interest expense increased by $11.7 million during the year ended December 31, 2018, as compared to 2017, primarily due to the issuance of our Term Loan in November 2017, from which a portion of the proceeds were used to repay and retire our previous credit facility. As a result, our total debt outstanding increased, as did the interest rate applicable to outstanding borrowings. Debt outstanding under our Term Loan was $175 million during the year ended December 31, 2018, while the weighted average debt outstanding under our previous credit facility and Term Loan during the year ended December 31, 2017 was approximately $95 million, with annualized weighted average interest rates applicable to these borrowings during these periods of approximately 9.9% and 6.9%, respectively.
Loss on extinguishment of debt — Our loss on extinguishment of debt in 2017 represents the write-off of net unamortized debt issuance costs associated with the extinguishment of our previous credit facility in November 2017.
Income tax expense (benefit) — Our effective income tax rate for the year ended December 31, 2018 was lower than the federal statutory rate in the United States, primarily due to valuation allowances, foreign currency translation, state taxes, and other permanent differences. For more detail, see Note 6, Income Taxes, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
General and administrative expense — Our general and administrative expense increased by $4.4 million, or 6%, during 2018, as compared to 2017, partially due to higher consulting and professional fees primarily incurred in connection with the early stages of replacing our legacy business applications, an increase in travel-related costs incurred during 2018, and an increase in compensation costs related to salary and wages, which was partially offset by a $1.5 million decrease in our phantom stock compensation expense, attributable to the decrease in fair value of our phantom stock unit awards.
Gain on dispositions of property and equipment, netOur net gain of $3.1 million on the disposition of property and equipment during 2018 was primarily for the sale of drill pipe and collars, various coiled tubing equipment, and fleet disposals, including the sale of five coiled tubing units, twelve wireline units, and two drilling rigs which were previously held for sale. Our net gain of $3.6 million on the disposition of property and equipment during 2017 was primarily for the sale of certain coiled tubing equipment and vehicles, as well as the loss of drill pipe in operation, for which we were reimbursed by the client, and the disposal of three cranes that were damaged.
Other incomeThe increase in our other income during the year ended December 31, 2018, as compared to 2017, is primarily related to interest earned on the investments made during 2018 in highly-liquid money-market mutual funds, partially offset by net foreign currency losses recognized for our Colombian operations.

Consolidated gross marginOur consolidated gross margin increased by 58% during 2017, as compared to 2016, as a result of higher activity for each of our drilling and production services business segments during the year ended December 31, 2017, as compared to 2016, as our industry continues to recover from an industry downturn. Spot prices also improved for all of our business segments throughout 2017. Of the $42.4 million increase in consolidated gross margin, 78% is attributable to our production services segments, primarily due to improved demand for our wireline services, while the remaining increase attributable to our drilling services business segments is primarily due to higher activity for our international drilling operations.
Drilling ServicesOur drilling services revenues increased by $51.4 million, or 43%, during 2017, as compared to 2016, while operating costs increased by $42.0 million, or 57%. The increases in our drilling services revenues and operating costs primarily resulted from a 42% increase in revenue days due to the increasing demand in our industry, especially in Colombia.

Our domestic drilling average revenues per day during 2017, as compared to 2016, decreased, while our average operating costs per day increased, due to the expiration of term contracts during 2016 that were entered into prior to

the downturn at higher revenue rates, many of which were terminated early. Thus, there were more revenue days during 2017 attributable to daywork activity versus revenue days associated with rigs that were earning but not working and incurring minimal operating costs during 2016.
Demand for drilling rigs influences the types of drilling contracts we are able to obtain, and the type of revenues we earn under our drilling contracts. As a result of the downturn in our industry, several of our clients terminated a number of their drilling contracts with us. Drilling rigs under contracts which are terminated early earn lower standby revenue rates, as compared to daywork rates, and incur minimal operating costs. Alternatively, turnkey drilling contracts result in higher average revenues per day and higher average operating costs per day as compared to daywork drilling contracts, and are more frequently entered into during periods of higher demand. The following table provides the percentages of our consolidated drilling services revenues by contract type fortype:
 Year ended December 31,
 2017 2016
Daywork contracts (not terminated early)100% 89%
Daywork contracts terminated early% 11%
Our international drilling fleet utilization steadily improved throughout 2017, culminating in a 75% utilization rate at the years endedend of 2017, versus 50% utilization at December 31, 2016, and 2015:

Ourwhich resulted in a significant increase in our average revenuesmargin per day. The substantial increase in average margin per day decreased by $2,980is largely a result of the low utilization in 2016, during which time we incurred certain fixed costs, as well as additional costs during the fourth quarter of 2016 to mobilize previously stacked rigs under new contracts, which resulted in a negative average margin per day during 2016.
Production ServicesOur revenues from production services increased by $118.0 million, or 11%75%, while our average operating costs per day decreased by $856 per day, or 5%, for the year ended December 31, 2016,during 2017, as compared to 2015. Our revenues per day decreased primarily due to the expiration of term contracts that were entered into in 2014 prior to the downturn at higher revenue rates, many of which were terminated early. Our operating costs per day decreased primarily due to our reduced cost structure, especially in Colombia, as well as a reduced contribution from our Colombian operations where costs are typically higher. The decreases in our operating costs per day from the reduced cost structure more than offset the increase resulting from a higher percentage of daywork revenues during 2016, as compared to 2015, versus revenues earned under contracts that were terminated early. For drilling contracts that were terminated early, the amount of drilling revenues and the number of revenue days for the years ended December 31, 2016 and 2015 are as follows:

Increases in response to the downturn in our industry, whichproduction services revenues and operating costs were led to decreased activity and increased pricing pressure for all our service offerings, especiallyby our wireline services and coiled tubing operations.business segment, which experienced a significant increase in completion-related activity as wells that were drilled but not completed during the downturn created higher demand for completion services as our industry continues to recover. The number of wireline jobs we completed decreasedincreased by 15%36% during 2016,2017, as compared to 2015,2016 while average revenue per job increased by 78%, which is largely due to completion-related jobs that earn higher revenue rates but also incur higher costs for the job materials consumed on these types of jobs.
Our well servicing and our coiled tubing services business segments experienced a more moderate increase in demand. Well servicing utilization decreasedincreased to 22%43% during 2017, from 41% during 2016, from 27% during 2015. The totalrepresenting a 4% increase in well servicing rig hours, for our well servicing fleet decreasedwhile average revenue per hour also increased by 36% during 2016,4%. Our coiled tubing revenue days increased by 13%, while the average revenue per day increased by 63%, which was primarily due to a larger proportion of the work performed with larger diameter coiled tubing units which typically earn higher revenue rates as compared to 2015, while pricing for these services decreased by 16%.smaller diameter coiled tubing units.

Depreciation and amortization expense —Our depreciation and amortization expense decreased by $36.6$15.5 million during 2016,2017, as compared to 2015,2016, primarily as a result of the impairment charges during 2015 to reduce the carrying valuesimpairments, dispositions of domestic and Colombia drilling rigs and coiled tubingvarious equipment, and intangible assets we placed as held for sale during 2016, as well as reduced capital expenditures during 2016 and 2017 due to their estimated fair values, and the sales and disposals of drilling rigs and equipment during 2015.downturn. During 2015,the year ended December 31, 2016, we recognized $10.3$11.6 million of depreciation on drilling and well servicing rigs, wireline units, and certain other equipment which were subsequently sold or placed as held for sale, and $3.8$1.3 million of amortization expense for the amortization of coiled tubingcertain intangible assets whichthat were impaired to zero atfully amortized by the end of 2015. The overall decrease in our depreciation expense was partially offset by $6.1 million of additional depreciation recognized during2016.
ImpairmentDuring the yearyears ended December 31, 2016 for the five new drilling rigs which we deployed in 2015.
During the year ended December 31,2017 and 2016, we recognized impairment charges of $1.9 million and $12.8 million, respectively, primarily to reduce the carrying values of certain assets which were classified as held for sale, to their estimated fair values based on expected salessale prices. During the year ended December 31, 2015, we recognized impairment charges of $129.2 million. For more detail, see Note 2,3, Property and Equipment, of the Notes to Consolidated Financial Statements, included in Part II, Item 8 Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Interest expense —Our interest expense increased by $4.7$1.1 million during 2016,the year ended December 31, 2017, as compared to 2015,2016, primarily due to the increased interest rate under our Revolving Credit Facility, which was amended in late 2015June 2016, and againthe issuance of our Term Loan in June 2016. November 2017. Proceeds from the issuance of our Term Loan were used to repay and retire the Revolving Credit Facility, and resulted in an increase in our total debt outstanding, as well as an increased rate applicable to the outstanding borrowings. Weighted average debt outstanding under our Revolving Credit Facility and/or Term Loan (beginning in November 2017) was approximately $95.4 million and $96.0 million during the years ended December 31, 2017 and 2016, respectively, while the weighted average interest rate on these borrowings during these periods was approximately 6.9% and 5.7%, respectively.

Income tax benefit —Our effective income tax rate for the year ended December 31, 20162017 was 8%, which is lower than the federal statutory rate in the United States primarily due to effects of recent tax law changes, valuation allowances, the effect of foreign currency translation, state taxes, and other permanent differences. For more detail, see Note 5,6, Income Taxes, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
General and administrative expense —Our general and administrative expense decreasedincreased by approximately $12.7$8.5 million, or 17%14%, during 2016,2017, as compared to 2015. This decrease is2016, primarily related to increased compensation costs. The increase in compensation cost was primarily due to a decrease$7.1 million increase in compensation and benefit costs during 2016 of $5.2 million, resulting primarily from the reduction in our workforce and reducedsalary, employee benefits and other efforts takenbonus expense during the year ended December 31, 2017, partially as a result of increased headcount to minimizeaccommodate higher activity levels, as well as increased incentive compensation based on improved company performance.
Gain on dispositions of property and equipment, net — Our net gain of $3.6 million on the disposition of various administrative costs suchproperty and equipment during 2017 included sales of drilling and coiled tubing equipment and vehicles, as rent, office and travel expenses.
well as the loss of drill pipe in operation, for which we were reimbursed by our client. Net gains in 2017 also included the disposal of three cranes that were damaged. Our net gain of $1.9 million on the disposition of property and equipment during the year ended December 31, 2016 was primarily related to a net gain on the sale of drilling rigs and the disposal of excess drill pipe. These gains during 2016 were partially offset by a loss on the disposition of damaged drilling equipment.
Other (income) expense — Our net gain of $4.3 million on the disposition of property and equipment during the year ended December 31, 2015 was primarily for the sale of 32 drilling rigs and other drilling equipment.
The increase in our other income is primarily related to net foreign currency gains recognized for our Colombian operations duringoperations.

Both our Drilling Services and Production Services Segments experienced a significant decline in activity during the year ended December 31, 2015, as compared to 2014, due to the downturn in our industry that began in 2015. Our combined margin decreased during 2015 as compared to 2014, primarily as a result of decreased activity and pricing pressure for all our service offerings. The decrease in combined margin was partially offset by an increase in average margin per day in our Drilling Services Segment from rigs that were earning but not working during 2015 and due to the disposal of 36 mechanical and lower horsepower electric drilling rigs from our fleet which generally earned lower margins per day, as well as various actions taken during 2015 to reduce costs.
In response to the downturn in our industry, we took several actions in 2015 to reduce costs and better scale our business to the reduced revenues. We reduced our total headcount by over 50%, reduced wage rates for our operations personnel reduced incentive compensationwhich increase when the availability of personnel is scarce;
materials and eliminated certain employment benefits. We closed nine location offices to reduce overhead and reduce associated lease payments, amended our revolving credit facility, and sold 32 drilling rigs and other drilling equipment for aggregate net proceeds of $53.6 million.
Our Drilling Services Segment’s revenues decreased by $267.2 million, or 52%, and our Drilling Services Segment’s operating costs decreased by $203.9 million, or 59%, during 2015 as compared to 2014, primarily resulting from a decrease in revenue days and lower average operating costs per day. Revenue days decreased primarily due to the significant reduction in demandsupplies used in our industry. Our average revenues per day increased by $1,231 per day, or 5%, for the year ended December 31, 2015, as compared to 2014. Our average revenues per day increased primarily because the drilling rigs which we removed from our fleet, as described above, were generally earning lower dayrates as compared to the rest of our fleet. Our average operating costs per day decreased by $1,809 per day, or 10%, during 2015 as compared to 2014, primarily due to reduced costs from drilling rigs which were early terminatedoperations;
equipment repair and were thus earning revenues while incurring minimal operating costs.
Demand for drilling rigs influences the types of drilling contracts we are able to obtain, and the type of revenues we earn under our drilling contracts. As a result of the downturn in our industry, several of our clients terminated a number of their drilling contracts with us. Drilling rigs under contracts which are terminated early earn lower standby revenue rates, as compared to daywork rates, and incur minimal operating costs. Alternatively, turnkey drilling contracts result in higher average revenues per day and higher average operating costs per day as compared to daywork drilling contracts, and are more frequently entered into during periods of higher demand. The following table provides the percentages of our drilling revenues by contract type for the years ended December 31, 2015 and 2014:

Our Production Services Segment's revenues decreased by $247.3 million, or 46%, during 2015 as compared to 2014, while operating costs decreased by $125.9 million, or 37%. The decreases in our Production Services Segment's revenues and operating costs are a result of the significantly reduced demand for our services in response to the downturn in our industry, which led to decreased activity and increased pricing pressure for all our service offerings, especially our wireline services and coiled tubing operations. The number of wireline jobs we completed decreased by 45% during 2015, as compared to 2014. The total rig hours for our well servicing fleet decreased by 25% during 2015, as compared to 2014. Our coiled tubing utilization decreased to 27% during 2015 from 51% during 2014.
Our depreciation and amortization expense decreased by $32.4 million during 2015, respectively, as compared to 2014, primarily as a result of the sales of drilling rigs and equipment during 2015 and 2014, as well as impairment charges to reduce the carrying values of certain drilling rigs to their estimated fair value, and partially offset by the increase in depreciation for the five new-builds which we deployed in 2015.
We recognized $129.2 million of impairment charges during the year ended December 31, 2015 to reduce the carrying values of our eight drilling rigs in Colombia and certain other assets associated with our Colombian operations, all our non-AC electric drilling rigs in our domestic fleet, the property and equipment of our coiled tubing operations, and the intangibles related to our coiled tubing operations to their estimated fair values. During the year ended December 31, 2014, we recorded impairment charges of $73.0 million, primarily to reduce the carrying values of 31 mechanical and lower horsepower drilling rigs to their estimated fair values, based on market appraisals. For more information, see Note 2, Property and Equipment, and Note 1, Organization and Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Our interest expense decreased by $17.6 million during 2015 as compared to 2014, due to the redemption of our 2010 and 2011 Senior Notes in 2014, which incurred interest at a higher rate than the 2014 Senior Notes which we issued in March 2014, as well as the repayments we made in 2014 and 2015 to reduce the level of debt outstanding under our Revolving Credit Facility.
Our loss on debt extinguishment during the year ended December 31, 2015 represents the write off of debt costs associated with the reduced borrowing capacity of our Revolving Credit Facility which was amended in September and again in December 2015. Our loss on debt extinguishment during the year ended December 31, 2014 represents the tender and redemption premiums and the write-off of net unamortized debt discount and debt issuance costs associated with the 2010 and 2011 Senior Notes that were redeemed in 2014.
Our effective income tax rate for the year ended December 31, 2015 was 19%, which is lower than the federal statutory rate in the United States, primarily due to valuation allowances on Colombian deferred tax assets, the effect of foreign currency translation, impairments, and other permanent differences. For more detail about the valuation allowances, see Note 5, Income Taxes, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Our general and administrative expense decreased by $29.5 million, or 29%, during 2015 as compared to 2014, primarily due to a $22.4 million decrease in compensation costs, net of approximately $2 million of severance costs incurred, as well as other efforts made during the year to minimize various administrative costs. The decrease in compensation expense is primarily due to the reduction in our workforce during 2015, a reduction in stock-basedmaintenance costs;

47




compensation duecosts to a decreaseupgrade existing equipment; and
costs to construct new equipment.
With the increases in certain long-term performance-based compensation plans' actual and projected achievement levels, and reduced incentive compensation for 2015.
Our gains on disposition of assets during the year ended December 31, 2015 are primarily related to the sale of 32 of our mechanical and lower horsepower drilling rigs. Our gains on disposition of assets during the year ended December 31, 2014 are primarily related to the sale of our trucking assets in February 2014.
In September 2014, we sold our fishing and rental services operations for total consideration of $16.1 million, resulting in a pretax gain of $10.7 million.
We recognized gains of $5.3 million related to settlements of litigation in our favor related to non-compete agreements during the year ended December 31, 2014.
Our other expense of $2.6 million for the year ended December 31, 2015 is primarily related to net foreign currency losses recognized for our Colombian operations due to the rise in the value of the U.S. dollar relative to the Colombian peso.
Inflation
Inflation has not had a significant impact on our operations during the three years ended December 31, 2016 and we believe that inflation will not have a significant near-term impact on our financial position.
Wage rates for our operations personnel are impacted by inflationary pressures when the demand for drilling and production services increases and the availability of personnel is scarce. Costs for equipment repairs and maintenance, upgrades and new equipment construction are also impacted by inflationary pressures when the demand for our services increases. As a result of the significantly reduced activity levels in our industry, we estimate that we experiencedinflation had a moderate decrease in both wage rates and equipment costsmodest impact on our operations during 2015 and 2016 for both our Drilling and Production Services Segments. However,through 2018. Although it varies by business, we expect that we will experience a moderate increase in 2017 as our industry continues to recover from the recent downturn.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements.expect significant inflationary pressure to impact our business in 2019.
Critical Accounting Policies and Estimates
The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue RecognitionIn May 2014, the FASB issued ASU No. 2014-09, a comprehensive new revenue recognition standard that supersedes nearly all pre-existing revenue recognition guidance. The standard, and Cost RecognitionOur Drilling Services Segment earns revenues by drilling oil and gas wells for our clients under daywork or turnkey contracts, which usually provide for the drilling ofits related amendments, collectively referred to as ASC Topic 606, outlines a single well. Drilling contractscomprehensive model for individual wells are usually completed in less than30days. We recognize revenues on daywork contracts for the days completedrevenue recognition based on the dayrate each contract specifies. core principle that a company will recognize revenue when promised goods or services are transferred to clients, in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services.
We recognize revenues from our turnkeyadopted this standard effective January 1, 2018 using the modified retrospective method, in which the standard has been applied to all contracts on the proportional performance basis, based on our estimateexisting as of the numberdate of daysinitial application, with the cumulative effect of applying the standard recognized in retained earnings. Accordingly, revenues for reporting periods ending after January 1, 2018 are presented under ASC Topic 606, while prior period amounts have not been adjusted and continue to complete each contract. Allbe reported under the previous revenue recognition guidance. In accordance with ASC Topic 606, we also adopted ASC Subtopic 340-40, Other Assets and Deferred Costs, Contracts with Customers, effective January 1, 2018, which requires that the incremental costs of ourobtaining or fulfilling a contract with a customer be recognized as an asset if the costs are expected to be recovered.
The adoption of these standards resulted in a cumulative effect adjustment of $0.1 million after applicable income taxes, which consists of the impact of the timing difference related to recognition of mobilization revenues are recognized net of applicable sales taxes.
With most drilling contracts, we receive payments contractually designated for the mobilization of rigs and other equipment. Payments received, andcosts. Mobilization costs incurred for the mobilization services are deferred and recognized on a straight line basisamortized over the related contract term. Costs incurred to relocate rigs and other drilling equipment to areas in which a contract has not been secured are expensed as incurred. Reimbursements that we receive for out-of-pocket expenses are recorded as revenue and the out-of-pocket expenses for which they relate are recorded as operating costs.
With most term drilling contracts, we are entitled to receive a full or reduced rateexpected period of revenue from our clients if they choose to place a rig on standby or to early terminate the contract before its original expiration term. Generally, these revenues are billed and collectedbenefit under ASC Subtopic 340-40, but were amortized over the remaininginitial contract term under the previous accounting guidance. The recognition of both mobilization revenues and costs begins when mobilization activity is completed under ASC Topic 606, but were recognized during the period of initial mobilization under the previous accounting guidance. Additionally, the opening balances of deferred mobilization costs were reclassified in accordance with ASC Subtopic 340-40, which requires classification of the entire deferred balance according to the duration of the original contract as the rig is often placed on standbyto which it relates, rather than fully released frombifurcating the contract,asset into current and thus may go back to work atnoncurrent portions.

Some of our drilling contracts contain “make-whole” provisions whereby if we are able to secure additional work for the rig with another client, then each party is entitled to a make-whole payment. If the dayratesaccounting under ASC Topic 606, and disclosures under the new contract are less than the dayrates in the original contract, we would be entitled to a reduced revenue dayratestandard, see Note 2, Revenue from the terminating client, and likewise, the terminating client may be entitled to a payment from us if the

A client may also chooseNotes to early terminate the contractConsolidated Financial Statements, included in Part II, Item 8, Financial Statements and make an upfront early termination payment basedSupplementary Data, of this Annual Report on a per day rate for the remaining term of the contract. Revenues derived from rigs placed on standby or from the early termination of term drilling contracts are deferred and recognized as the amounts become fixed or determinable, over the remainder of the original term or when the rig is sold.
Our Production Services Segment earns revenues for well servicing, wireline services and coiled tubing services pursuant to master services agreements based on purchase orders, contracts or other arrangements with the client that include fixed or determinable prices. Production services jobs are generally short-term and are charged at current market rates. Production service revenue is recognized when the service has been rendered and collectability is reasonably assured.
Long-lived tangible and intangible assets—We evaluate for potential impairment of long-lived tangible and intangible assets subject to amortization when indicators of impairment are present. Circumstances that could indicate a potential impairment include significant adverse changes in industry trends, economic climate, legal factors, and an adverse action or assessment by a regulator. More specifically, significant adverse changes in industry trends include significant declines in revenue rates, utilization rates, oil and natural gas market prices and industry rig counts.In performing an impairment evaluation, we estimate the future undiscounted net cash flows from the use and eventual disposition of long-lived tangible and intangible assets grouped at the lowest level that cash flows can be identified. For our Production Services Segment, we perform an impairment evaluation and estimate future undiscounted cash flows for the individual reporting units (well servicing, wireline and coiled tubing). For our Drilling Services Segment, we perform an impairment evaluation and estimate future undiscounted cash flows for individual domestic drilling rig assets and for our Colombian drilling rig assets as a group.If the sum of the estimated future undiscounted net cash flows is less than the carrying amount of the asset group, then we determine the fair value of the asset group. The amount of an impairment charge is measured as the difference between the carrying amount and the fair value of the assets.The assumptions used in the impairment evaluation for long-lived assets are inherently uncertain and require management judgment.
Deferred taxes—We provide deferred taxes for the basis differences in our property and equipment between financial reporting and tax reporting purposes and other costs such as compensation, net operating loss carryforwards, employee benefit and other accrued liabilities which are deducted in different periods for financial reporting and tax reporting purposes. For property and equipment, basis differences arise from differences in depreciation periods and methods and the value of assets acquired in a business acquisition where we acquire an entity rather than just its assets. For financial reporting purposes, we depreciate the various components of our drilling rigs, well servicing rigs, wireline units and coiled tubing units over 1 to 25 years and refurbishments over 3 to 5 years, while federal income tax rules require that we depreciate drilling rigs, well servicing rigs, wireline units and coiled tubing units over 5 years. Therefore, in the first 5 years of our ownership of a drilling rig, well servicing rig, wireline unit or coiled tubing unit, our tax depreciation exceeds our financial reporting depreciation, resulting in our providing deferred taxes on this depreciation difference. After 5 years, financial reporting depreciation exceeds tax depreciation, and the deferred tax liability begins to reverse.Form 10-K.
Accounting estimates—Material estimates that are particularly susceptible to significant changes in the near term relate to our recognitionestimates of certain variable revenues and amortization periods of certain deferred revenues and costs for turnkey contracts, our estimate of the allowance for doubtful accounts, our determination of depreciation and amortization expenses,associated with drilling daywork contacts, our estimates of projected cash flows and fair values for impairment evaluations, our estimate of the valuation allowance for deferred tax assets, our estimate of the liability relating to the self-insurance portion of our health and workers’ compensation insurance and our estimate of compensation related accrualsaccruals.
In accordance with ASC Topic 606, Revenue from Contracts with Customers, we estimate certain variable revenues associated with the demobilization of our drilling rigs under daywork drilling contracts. We also make estimates of the applicable amortization periods for deferred mobilization costs, and for mobilization revenues related to cancelable term contracts which represent a material right to our estimateclients. These estimates and assumptions are described in more detail in Note 2, Revenue from Contracts with Customers. In order to make these estimates, management considers all the facts and circumstances pertaining to each particular contract, our past experience and knowledge of sales tax audit liability.current market conditions.
In accordance with ASC Topic 360, Property, Plant and Equipment, we monitor all indicators of potential impairments, and we evaluate for potential impairment of long-lived assets when indicators of impairment are present, which may include, among other things, significant adverse changes in industry trends (including revenue rates, utilization rates,

For turnkey drilling contracts, we recognize revenuesoil and accrue estimated costs based onnatural gas market prices, and industry rig counts). Due to adverse factors affecting our estimatewell servicing operations, including increased competition and labor shortages in certain well servicing markets, and lower than anticipated utilization, all of the number of days to complete each contract and our estimate of the total costs to complete the contract. If we anticipate a loss on a contract in progress duewhich contributed to a changedecline in our cost estimate,projected cash flows for the well servicing reporting unit, we accrueperformed an impairment analysis of this reporting unit at September 30, 2018. As a result of this analysis, we concluded that this reporting unit was not at risk of impairment because the entire amountsum of the estimated loss, including all costs that are includedfuture undiscounted net cash flows for our well servicing reporting unit was significantly in excess of the carrying amount.
The most significant inputs used in our revised estimated cost to complete that contract, in our consolidated statement of operations for that reporting period. We did not experience a lossimpairment analysis include the turnkey contract completed during the year ended December 31, 2016. We incurred a total loss of $0.5 million on 3 of the 17 turnkey contracts completed during the year ended December 31, 2015,projected utilization and we incurred a total loss of $1.2 million on 13 of the 106 turnkey contracts completed during the year ended December 31, 2014. Revenues and costs during a reporting period could be affected for contracts in progress at the end of a reporting period which have not been completed before our financial statements for that period are released. As of December 31, 2016, we had no turnkey contracts in progress.
We estimate an allowance for doubtful accounts based on the creditworthinesspricing of our clientsservices, as well as general economic conditions. We evaluate the creditworthinessestimated proceeds upon any future sale or disposal of the assets, all of which are classified as Level 3 inputs as defined by ASC Topic 820, Fair Value Measurements and Disclosures. The assumptions we use in the evaluation for impairment are inherently uncertain and require management judgment. Although we believe the assumptions and estimates used in our impairment analysis are reasonable, different assumptions and estimates could materially impact the analysis and resulting conclusions. If commodity prices remain at current levels for an extended period of time, or if the demand for any of our clients based on commercial credit reports, trade references, bank references, financial information, production informationservices decreases below what we are currently projecting, our estimated cash flows may decrease, and if any past experience we have with the client. Consequently, any change in those factors could affect our estimate of our allowance for doubtful accounts. In some instances, we require new clients to establish escrow accounts or make prepayments. We had an allowance for doubtful accounts of $1.7 million at December 31, 2016.
Our determination of the useful lives of our depreciable assets, which directly affects our determination of depreciation expense and deferred taxes is also a critical accounting estimate. A decrease in the useful life of our property and equipment would increase depreciation expense and reduce deferred taxes. We provide for depreciation of our drilling, production, transportation and other equipment on a straight-line method over useful lives thatforegoing were to occur, we have estimated and that range from 1 to 25 years. We record the same depreciation expense whether a drilling rig, well servicing rig, wireline unit or coiled tubing unit is idle or working. Our estimates of the useful lives of our drilling, production, transportation and other equipment are based on our almost 50 years of experience in the oilfield services industry with similar equipment.
We evaluate for potential impairment of long-lived tangible and intangible assets subject to amortization when indicators of impairment are present. During the year ended December 31, 2016, we recognizedcould incur impairment charges of $12.8 million, primarily to reduceon the carrying values of certain assets which were classified as held for sale, to their estimated fair value based on expected sales prices. During the years ended December 31, 2015 and 2014, we recognized impairment charges of $129.2 million and $73.0 million, respectively.related assets. For more detail,information, see Note 2,3, Property and Equipment, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Despite the modest recovery in commodity prices in the latter half of 2016, we continue to monitor all indicators of potential impairments in accordance with ASC Topic 360, Property, Plant and Equipment. Business conditions and our projected cash flows for our Colombian operations improved as compared to the projections used for the impairment analysis in 2015, therefore we did not perform any impairment testing on this business in 2016. However, due to lower than anticipated operating results in 2016 and a decline in our projected cash flows for the coiled tubing reporting unit, we performed an impairment analysis of our coiled tubing long-lived assets at September 30, 2016 which indicated that our projected net undiscounted cash flows associated with the coiled tubing reporting unit were in excess of the net carrying value of the assets, and thus no impairment was present. The most significant inputs used in our impairment analysis of our coiled tubing operations include the projected utilization and pricing of our coiled tubing services, which are classified as Level 3 inputs as defined by Accounting Standards Codification (ASC) Topic 820, Fair Value Measurements and Disclosures.
The assumptions used in the impairment evaluation for long-lived assets are inherently uncertain and require management judgment. Although we believe the assumptions and estimates used in our impairment analyses are reasonable and appropriate, different assumptions and estimates could materially impact the analyses and resulting conclusions. If the demand for our services remains at current levels or declines further and any of our assets become or remain idle for an extended amount of time, then our estimated cash flows may further decrease, and the probability of a near term sale may increase. If any of the foregoing were to occur, we may incur additional impairment charges.

As of December 31, 2016,2018, we had $131.4$96.8 million and $9.6 million of deferred tax assets related to domestic and foreign net operating losses, respectively, that are available to reduce future taxable income. In assessing the realizability of our deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. As a result, we have a valuation allowance that fully offsets our foreign and domestic federal deferred tax assets as of December 31, 2016, we determined that a2018. The valuation allowance should be recorded for a portion of our domestic deferred tax assets, which has been factored into the estimated annual tax rate applied throughout 2016, and is the primary factor causing our effective tax rate to be significantly lower than the statutory rate of 35%. We also have a valuation allowance that fully offsets our $21.1 million of foreign deferred tax assets at December 31, 2016.rate. For more information, see Note 5,6, Income Taxes, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Our accruedWe use a combination of self-insurance and third-party insurance premiums and deductibles asfor various types of December 31, 2016 include accruals for costs incurred under the self-insurance portion of our health insurance of approximately $2.0 million and our workers’ compensation, general liability and auto liability insurance of approximately $4.4 million.coverage. We have stop-loss coverage of $200,000 per covered individual per year under our health insurance and a deductible of $500,000 per occurrence under our workers’ compensation insurance. We have a deductible of $250,000 per occurrence and an additional $250,000 annual aggregate deductible under both our general liability insurance and auto liability insurance. At December 31, 2018, our accrued insurance premiums and deductibles include approximately $1.8 million of accruals for costs incurred under the self-insurance portion of our health insurance and approximately $3.0 million of accruals for costs associated with our workers’ compensation insurance. We accrue for these costs as claims are incurred using an actuarial calculation that is based on industry and our company’s historical claim development data, and we accrue the costscost of administrative services associated with claims processing.
Our compensation expense includes estimates for certain of our long-term incentive compensation plans which have performance-based award components dependent upon our performance over a set performance period, as compared to the performance of a pre-defined peer group. The accruals for these awards include estimates which affect our compensation expense, employee related accruals and equity. The accruals are adjusted based on actual achievement levels at the end of the pre-determined performance periods.
Additionally, our phantom stock unit awards are classified as liability awards under ASC Topic 718, We have received an increased numberCompensation—Stock Compensation, because we expect to settle the awards in cash when they vest, and are remeasured at fair value at the end of noticeseach reporting period until they vest. The change in recent years from state taxing authorities for auditsfair value is recognized as a current period compensation expense in our consolidated statements of salesoperations. Therefore, changes in the inputs used to measure fair value can result in volatility in our compensation expense. This volatility increases as the phantom stock awards approach the vesting date. For more information, see Note 9, Equity Transactions and use tax obligations. We are currently undergoing sales and use tax audits for multi-year periods and we are working to resolve all relevant issues. As of both December 31, 2016 and December 31, 2015, our accrued liability was $0.6 million based on our estimateStock-Based Compensation Plans, of the salesNotes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and use tax obligations that are expected to result from these audits.

We believe that such an outcome would not have a material adverse effectthis Annual Report on our results of operations or financial position. Because certain of these audits are in a preliminary stage, an estimate of the possible loss or range of loss from an adverse result in all or substantially all of these cases cannot reasonably be made.Form 10-K.

ItemITEM 7A.Quantitative and Qualitative Disclosures About Market RiskQUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
We are subject to interest rate market risk on our variable rate debt. As of December 31, 20162018, we had $46 million outstandingthe principal amount under our Revolving Credit Facility,Term Loan was $175 million, which is our only variable rate debt.debt with an outstanding balance. The impact of a hypothetical 1% increase or decrease in interest rates on this amount of debt would have resulted in a corresponding increase or decrease, respectively, in interest expense of approximately $0.5 million, and a corresponding increase or decrease, respectively, in net income of approximately $0.31.8 million during the year ended December 31, 20162018. This potential increase or decrease is based on the simplified assumption that the level of variable rate debt remains constant with an immediate across-the-board interest rate increase or decrease as of January 1, 20162018.
Foreign Currency Risk
While the U.S. dollar is the functional currency for reporting purposes for our Colombian operations, we enter into transactions denominated in Colombian pesos.Pesos. Nonmonetary assets and liabilities are translated at historical rates and monetary assets and liabilities are translated at exchange rates in effect at the end of the period. Income statement accounts are translated at average rates for the period. As a result, Colombian Peso denominated transactions are affected by changes in exchange rates. We generally accept the exposure to exchange rate movements without using derivative financial instruments to manage this risk. Therefore, both positive and negative movements in the Colombian Peso currency exchange rate against the U.S. dollar have and will continue to affect the reported amount of revenues, expenses, profit, and assets and liabilities in our consolidated financial statements.
The impact of currency rate changes on our Colombian Peso denominated transactions and balances resulted in net foreign currency gainslosses of $0.4$0.3 million for the year ended December 31, 20162018.

Basis for Opinion
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 accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB.

Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
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, Pioneer Energy Services Corp. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Pioneer Energy Services Corp. and subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2016, and our report dated February 17, 2017 expressed an unqualified opinion on those consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Organization and Summary of Significant Accounting Policies
Business
Pioneer Energy Services Corp. provides land-based drilling services and production services to a diverse group of independent and large oil and gas exploration and production companies in the United States and internationally in Colombia. We also
Our drilling services business segments provide two of ourcontract land drilling services (coiled tubing and wireline services) offshorethrough three domestic divisions which are located in the Gulf of Mexico.
As of December 31, 2016, ourMarcellus/Utica, Permian Basin and Eagle Ford, and Bakken regions, and internationally in Colombia. We provide a comprehensive service offering which includes the drilling rig, fleet is 100% pad-capable, consisting of 16 AC rigs in the US and eight SCR rigs in Colombia. In addition to our drilling rigs, we provide the drilling crews, supplies and most of the ancillary equipment needed to operate our drilling rigs. TheOur drilling rigs are equipped with 1,500 horsepower or greater drawworks, are 100% pad-capable and offer the latest advancements in pad drilling. The following table summarizes our current rig fleet are currently assigned to the following divisions:count and composition for each drilling services business segment:

Drilling Contracts
We obtain our contracts for drilling oil and natural gas wells either through competitive bidding or through direct negotiations with existing or potential clients. Our drilling contracts generally provide for compensation on a daywork basis, and sometimes on a turnkey basis. Contract terms generally depend on the complexity and risk of operations, the on-site drilling conditions, the type of equipment used, and the anticipated duration of the work to be performed. Spot market contracts generally provide for the drilling of a single well and typically permit the client to terminate on short notice. We typically enter into longer-term drilling contracts for our newly constructed rigs and/or during periods of high rig demand.
As of December 31, 2016, 13 of our 16 domestic drilling rigs are earning revenues, nine of which are under term contracts, and four of the drilling rigs in Colombia are earning revenues, three of which are under term contracts. The term contracts in Colombia are cancelable by our client without penalty if 30 days’ notice is provided, and by us if rig operations are suspended without an associated dayrate. We are actively marketing our idle drilling rigs in Colombia to various operators and we are evaluating other options, including the possibility of the sale of some or all of our assets in Colombia.

Basis of Presentation
The accompanying consolidated financial statements include the accounts of Pioneer Energy Services Corp. and our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America.
Use of Estimates In preparing the accompanying consolidated financial statements, we make various estimates and assumptions that affect the amounts of assets and liabilities we report as of the dates of the balance sheets and income and expenses we report for the periods shown in the income statements and statements of cash flows. Our actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant changes in the near term relate to our recognitionestimates of certain variable revenues and amortization periods of certain deferred revenues and costs for turnkey contracts, our estimate of the allowance for doubtful accounts, our determination of depreciation and amortization expenses,associated with drilling daywork contacts, our estimates of projected cash flows and fair values for impairment evaluations, our estimate of the valuation allowance for deferred tax assets, our estimate of the liability relating to the self-insurance portion of our health and workers’ compensation insurance and our estimate of compensation related accruals and our estimate of sales tax audit liability.accruals.
Subsequent Events In preparing the accompanying consolidated financial statements, we have reviewed events that have occurred after December 31, 2016,2018, through the filing of this Annual Report on Form 10-K, for inclusion as necessary.

Change in Accounting Principle and Recently Issued Accounting Standards
Changes to accounting principles generally accepted in the United States of America (“U.S. GAAP”) are established by the Financial Accounting Standards Board (FASB) in the form of Accounting Standards Updates (ASUs) to the FASB Accounting Standards Codification (ASC). We consider the applicability and impact of all ASUs. Any ASUs not listed below were assessed and determined to be either not applicable or are expected to have an immaterial impact on our consolidated financial position and results of operations.
Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, a comprehensive new revenue recognition standard that supersedes nearly all pre-existing revenue recognition guidance. The standard, and its related amendments, collectively referred to as ASC Topic 606, outlines a single comprehensive model for revenue recognition based on the core principle that a company will recognize revenue when promised goods or services are transferred to clients, in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services.
Foreign CurrenciesWe adopted this standard effective January 1, 2018 using the modified retrospective method, in which the standard has been applied to all contracts existing as of the date of initial application, with the cumulative effect of applying the standard recognized in retained earnings. Accordingly, revenues for reporting periods ending after January 1, 2018 are presented under ASC Topic 606, while prior period amounts have not been adjusted and continue to be reported under the previous revenue recognition guidance. In accordance with ASC Topic 606, we also adopted ASC Subtopic 340-40, Other Assets and Deferred Costs, Contracts with Customers, effective January 1, 2018, which requires that the incremental costs of obtaining or fulfilling a contract with a customer be recognized as an asset if the costs are expected to be recovered.
Our functional currencyThe adoption of these standards resulted in a cumulative effect adjustment of $0.1 million after applicable income taxes, which consists of the impact of the timing difference related to recognition of mobilization revenues and costs. Mobilization costs incurred are deferred and amortized over the expected period of benefit under ASC Subtopic 340-40, but were amortized over the initial contract term under the previous accounting guidance. The recognition of both mobilization revenues and costs begins when mobilization activity is completed under ASC Topic 606, but were recognized during the period of initial mobilization under the previous accounting guidance. Additionally, the opening balances of deferred mobilization costs were reclassified in accordance with ASC Subtopic 340-40, which requires classification of the entire deferred balance according to the duration of the original contract to which it relates, rather than bifurcating the asset into current and noncurrent portions.
For more information about the accounting under ASC Topic 606, and disclosures under the new standard, see Note 2, Revenue from Contracts with Customers.
Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases, which among other things, requires lessees to recognize substantially all leases on the balance sheet, with expense recognition that is similar to the current lease standard, and aligns the principles of lessor accounting with the principles of the FASB’s new revenue guidance (referenced above).
In July 2018, the FASB issued ASU No. 2018-11, Leases: Targeted Improvements, which provides an option to apply the guidance prospectively, and provides a practical expedient allowing lessors to combine the lease and non-lease components of revenues where the revenue recognition pattern is the same and where the lease component, when accounted for separately, would be considered an operating lease. The practical expedient also allows a lessor to account for the combined lease and non-lease components under ASC Topic 606, Revenue from Contracts with Customers, when the non-lease component is the predominant element of the combined component. As a lessor, we expect to apply the practical expedient which would allow us to continue to recognize our revenues (both lease and service components) under ASC Topic 606, and continue to present them as one revenue stream in our consolidated statements of operations.
As a lessee, this standard will primarily impact our accounting for long-term real estate and office equipment leases, for which we will recognize a right-of-use asset and a corresponding lease liability on our consolidated balance sheet. We will apply this guidance prospectively, beginning January 1, 2019 and currently estimate the impact on our balance sheet to be approximately $10 million. We are nearing completion of our process to implement a lease accounting system for our foreign subsidiaryleases, including the conversion of our existing lease data to the new system and implementing relevant internal controls and procedures.

Significant Accounting Policies and Detail of Account Balances
Cash and Cash Equivalents — As of December 31, 2018, we had $13.0 million of cash and $40.6 million of cash equivalents, consisting of investments in Colombiahighly-liquid money-market mutual funds. We had no cash equivalents at December 31, 2017.
Restricted Cash — Our restricted cash balance reflects the portion of net proceeds from the issuance of our senior secured term loan which are currently held in a restricted account until the completion of certain administrative tasks related to providing access rights to certain of our real property.
Revenue — Production services jobs are varied in nature, but typically represent a single performance obligation, either for a particular job, a series of distinct jobs, or a period of time during which we stand ready to provide services as our client needs them. Revenue is recognized for these services over time, as the U.S. dollar. Nonmonetary assets and liabilitiesservices are translated at historical rates and monetary assets and liabilities are translated at exchange rates in effect at the end of the period. Income statement accounts are translated at average rates for the period. Gains and losses from remeasurement of foreign currency financial statements into U.S. dollars and from foreign currency transactions are included in other income or expense.
Revenue and Cost Recognition
Drilling Services—performed. Our Drilling Services Segment earnsdrilling services business segments earn revenues by drilling oil and gas wells for our clients under daywork or turnkeycontracts. Daywork contracts are comprehensive agreements under which usuallywe provide fora comprehensive service offering, including the drilling rig, crew, supplies and most of the ancillary equipment necessary to operate the rig. We account for our services provided under daywork contracts as a single performance obligation comprised of a single well. Drilling contracts for individual wellsseries of distinct time increments which are usually completedsatisfied over time. Accordingly, dayrate revenues are recognized in less than 30 days. We recognize revenues on daywork contracts for the days completed based onperiod during which the dayrate each contract specifies. We recognize revenues from our turnkey contracts on the proportional performance basis, based on our estimate of the number of days to complete each contract.services are performed. All of our revenues are recognized net of applicable sales taxes.
With most drilling contracts, we receive payments contractually designated fortaxes, when applicable. For more information about the mobilization of rigs and other equipment. Payments received, and costs incurred for the mobilization services are deferred and recognized on a straight line basis over the related contract term. Costs incurred to relocate rigs and other drilling equipment to areas in which a contract has not been secured are expensed as incurred. Reimbursements that we receive for out-of-pocket expenses are recorded as revenue and the out-of-pocket expenses for which they relate are recorded as operating costs.accounting under ASC Topic 606, see Note 2, Amortization of deferred mobilization revenues was $1.6 million, $1.1 million and $4.6 million for the years ended December 31, 2016, 2015 and 2014, respectively.
With most term drilling contracts, we are entitled to receive a full or reduced rate of revenueRevenue from our clients if they choose to place a rig on standby or to early terminate the contract before its original expiration term. Generally, these revenues are billed and collected over the remaining term of the contract, as the rig is often placed on standby rather than fully released from the contract, and thus may go back to work at the client’s decision any time before the end of the contract. Some of our drilling contracts contain “make-whole” provisions whereby if we are able to secure additional work for the rigContracts with another client, then each party is entitled to a make-whole payment. If the dayrates under the new contract are less than the dayrates in the original contract, we would be entitled to a reduced revenue dayrate from the terminating client, and likewise, the terminating client may be entitled to a payment from us if the new contract dayrates exceed those of the original contract. A client may also choose to early terminate the contract and make an upfront early termination payment based on a per day rate for the remaining term of the contract.

61




Revenues derived from rigs placed on standby or from the early termination of term drilling contracts are deferred and recognized as the amounts become fixed or determinable, over the remainder of the original term or when the rig is sold. As a result of the downturn that began in late 2014, term contracts for 19 of our drilling rigs were terminated early, including three that were terminated in early 2016. As of December 31, 2016, all of these contracts’ terms have expired and all the associated revenue from the early terminations has been recognized.

Turnkey Drilling Contracts—Under a typical turnkey drilling contract, we agree to drill a well for our client to a specified depth and under specified conditions for a fixed price. We use the proportional performance basis to recognize revenue on our turnkey contracts. We accrue estimated contract costs on turnkey contracts for each day of work completed based on our estimate of the total costs to complete the contract divided by our estimate of the number of days to complete the contract. Contract costs include labor, materials, supplies, repairs and maintenance, operating overhead allocations and allocations of depreciation and amortization expense. If we anticipate a loss on a contract in progress due to a change in our cost estimate, we accrue the entire amount of the estimated loss, including all costs that are included in our revised estimated cost to complete that contract, in our consolidated statement of operations for that reporting period. Our actual results for a contract could differ significantly if our cost estimates for that contract are later revised from our original cost estimates for a contract in progress at the end of a reporting period which was not completed prior to the release of our financial statements.
Production Services—Our Production Services Segment earns revenues for well servicing, wireline services and coiled tubing services pursuant to master services agreements based on purchase orders, contracts or other arrangements with the client that include fixed or determinable prices. Production services jobs are generally short-term and are charged at current market rates. Production service revenue is recognized when the service has been rendered and collectability is reasonably assured.
Concentration of Clients—We derive a significant portion of our revenue from a limited number of major clients. For the years ended December 31, 2016, 2015 and 2014, our drilling and production services to our top three clients accounted for approximately 26%, 29%, and 28%, respectively, of our revenue. For a detail of our three largest clients as a percentage of our total revenues during the last three fiscal years, see Item 1—“Business” in Part I of this Annual Report on Form 10-K.
Cash and Cash Equivalents
For purposes of the statements of cash flows, we consider all highly liquid instruments purchased with a maturity of three months or less to be cash equivalents. Cash equivalents consist of investments in money market accounts. We had no cash equivalents at December 31, 2016. Cash equivalents at December 31, 2015 were $1.3 million.
Trade and Unbilled Accounts Receivable
We record trade accounts receivable at the amount we invoice to our clients. These accounts do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our accounts receivable as of the balance sheet date. We determine the allowance based on the credit worthiness of our clients and general economic conditions. Consequently, an adverse change in those factors could affect our estimate of our allowance for doubtful accounts.

62




We review our allowance for doubtful accounts on a monthly basis. Our typical drilling contract provides for payment of invoices in 30 days. We generally do not extend payment terms beyond 30 days and have not extended payment terms beyond 90 days for any of our domestic contracts in the last three fiscal years. Our production services terms generally provide for payment of invoices in 30 days. Balances more than 90 days past due are reviewed individually for collectability. We charge off account balances against the allowance after we have exhausted all reasonable means of collection and determined that the potential for recovery is remote. We do not have any off-balance sheet credit exposure related to our clients.

Unbilled Accounts Receivable
The asset “unbilled receivables” representsunbilled receivables represent revenues we have recognized in excess of amounts billed on drilling contracts and production services completed but not yet invoiced. We typically invoicecompleted. For more information, see Note 2, Revenue from Contracts with Customers.
Other Receivables — Our other receivables primarily consist of recoverable taxes related to our clients at 15-day intervals during the performance of daywork drilling contracts and upon completion of the daywork contract. Turnkey drilling contracts are invoiced upon completion of the contract.

Inventories
Inventories primarily consist of drilling rig replacement parts and supplies held for use by our Drilling Services Segment’sdrilling operations in Colombia, and supplies held for use by our Production Services Segment’swireline and coiled tubing operations. Inventories are valued at the lower of cost (first in, first out or actual) or marketnet realizable value.
Prepaid Expenses and Other Current Assets
Prepaid expenses and other current assets include items such as insurance, rent deposits, software subscriptions and other fees. We routinely expense these items in the normal course of business over the periods these expenses benefit. Prepaid expenses and other current assets also include the current portion of deferred mobilization costs for certainshort-term drilling contracts that are recognized on a straight-line basis over the contract term.contracts.
Property and Equipment
Property and equipment are carried at cost less accumulated depreciation. Depreciation is provided for our assets over the estimated useful lives of the assets using the straight-line method. We record the same depreciation expense whether a rigour equipment is idle or working. We charge our expenses for maintenance and repairs to operating costs. We capitalize expenditures for renewals and betterments to the appropriate property and equipment accounts.

63




Intangible Assets
Our intangible assets were recorded in connection with the acquisitions of production services businesses and are subject to amortization. As of December 31, 2016 and 2015, the estimated useful lives and components of our intangible asset classes are as follows:
   December 31,
   2016 2015
 Lives (amounts in thousands)
Client relationships:8 - 9    
Cost  $1,547

Non-compete agreements:7    
Cost  150
 575
Accumulated amortization  (145) (541)
   $403
 $1,944
The cost of our client relationships are amortized using the straight-line method over their respective estimated economic useful lives and amortization expense for our non-compete agreements is calculated using the straight-line method over the period of the agreements. Amortization expense was $1.5 million, $7.9 million and $8.0 million for the years ended December 31, 2016, 2015 and 2014, respectively. Amortization expense is estimated to be approximately $0.2 million for each of the years ending December 31, 2017 and 2018. Actual amortization amounts may be different due to future acquisitions, impairments, changes in amortization periods, or other factors.
During 2016, we removed $12.1 million and $0.4 million of fully amortized capitalized client relationship and non-compete agreement costs, respectively. Doing so had no net impact to our consolidated balance sheet or consolidated statement of operations as of and for the year ending December 31, 2016.
As a result of the downturn which began in late 2014 and worsened through 2015, our projected cash flows declined and we performed an impairment analysis of our long-lived tangible and intangible assets, which resulted in an impairment charge of $14.3 million recognized in 2015 that reduced the carrying value of our coiled tubing intangible assets to zero. We used an income approach to estimate the fair value of our coiled tubing services reporting unit. The most significant inputs used in our impairment analysis of our coiled tubing operations include the projected utilization and pricing of our coiled tubing services, which are classified as Level For more information, see Note 3, inputs as defined by Accounting Standards Codification (ASC) Topic 820, Fair Value Measurements and Disclosures. Although we believe the assumptions and estimates used in our impairment analyses are reasonable and appropriate, different assumptions and estimates could materially impact the analyses and resulting conclusions. We assumed a 13% discount rate to estimate the fair value of the coiled tubing services reporting unit. A decrease in this assumption of 5% would have resulted in a decrease to our impairment charge of approximately $2 million. An increase of 1% in either the utilization or pricing assumptions would have resulted in a decrease to our impairment charge of approximately $1 million or $2 million, respectively. Our impairment analysis also resulted in an impairment to our coiled tubing tangible long-lived assets in 2015, which is discussed in more detail in Note 2, Property and Equipment.
Other Long-TermNoncurrent Assets
Other long-termnoncurrent assets consist of deferred mobilization costs on long-term drilling contracts, cash deposits related to the deductibles on our workers’ compensation insurance policies, and deferred compensation plan investments and the long-term portion of deferred mobilization costs.investments.
Other Current Liabilities
Accrued Expenses Our other accrued expenses include accruals for items such as sales taxes, property taxes, withholding tax sales tax,liability related to our international operations, and professional and other fees. We routinely expense these items in the normal course of business over the periods these expenses benefit.

64




Other Long-TermNoncurrent Liabilities
Our other long-termnoncurrent liabilities consist of the noncurrent portion of deferred mobilization revenues, the noncurrent portion of liabilities associated with our long-term compensation plans, and deferred lease liabilities,liabilities.

60




Insurance Recoveries, Accrued Insurance Claims and Settlements, and Accrued Premiums and Deductibles — We use a combination of self-insurance and third-party insurance for various types of coverage. Our accrued premiums and deductibles include the long-termpremiums and estimated liability for the self-insured portion of deferred mobilization revenues.costs associated with our health, workers’ compensation, general liability and auto liability insurance. Our insurance recoveries receivables and our accrued liability for insurance claims and settlements represent our estimate of claims in excess of our deductible, which are covered and managed by our third-party insurance providers, some of which may ultimately be settled by the insurance provider in the long-term. These are presented in our consolidated balance sheets as current due to the uncertainty in the timing of reporting and payment of claims. For more information, see Note 10, Employee Benefit Plans and Insurance.
Treasury Stock
Treasury stock purchases are accounted for under the cost method whereby the cost of the acquired common stock is recorded as treasury stock. Gains and losses on the subsequent reissuance of treasury stock shares are credited or charged to additional paid in capital using the average cost method.
Stock-based Compensation
We recognize compensation cost for stock option, restricted stock and restricted stock unitour stock-based compensation awards based on the fair value estimated in accordance with ASC Topic 718, Compensation—Stock Compensation.Compensation, and we recognize forfeitures when they occur. For our awards with graded vesting, we recognize compensation expense on a straight-line basis over the service period for each separately vesting portion of the award as if the award was, in substance, multiple awards.
We receive a tax deduction for certain stock option exercises during the period the options are exercised, generally for the excess of the fair market value of our stock on the date of exercise over the exercise price of the options. In accordance with ASC Topic 718, when we have excess tax benefits resulting from the exercise of stock options, we report them as financing cash flows in our consolidated statement of cash flows, unless otherwise disallowed under ASC Topic 740, For more information, see Note 9, Income TaxesEquity Transactions and Stock-Based Compensation Plans.
Income Taxes
We follow the asset and liability method of accounting for income taxes, under which we recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. We measure our deferred tax assets and liabilities by using the enacted tax rates we expect to apply to taxable income in the years in which we expect to recover or settle those temporary differences. The effect of a change in tax rates on deferred tax assets and liabilities is reflected in income in the period during which the change occurs. A recent change in Colombia tax rates is described inof enactment. For more detail ininformation, see Note 5,6, Income Taxes.
Foreign Currencies — Our functional currency for our foreign subsidiary in Colombia is the U.S. dollar. Nonmonetary assets and liabilities are translated at historical rates and monetary assets and liabilities are translated at exchange rates in effect at the end of the period. Income statement accounts are translated at average rates for the period. Gains and losses from remeasurement of foreign currency financial statements into U.S. dollars and from foreign currency transactions are included in other income or expense.
Related-Party Transactions
During each of the years ended December 31, 2016, 2015,2018, 2017 and 2014,2016, the Company paid approximately $0.2 million $0.2 million and $0.4 million, respectively, for trucking and equipment rental services received from Gulf Coast Lease Service, which represented arms-length transactions, totransactions.

Recently Issued Accounting Standards
Revenue Recognition. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance. The standard outlines a single comprehensive model for revenue recognition based on the core principle that a company will recognize revenue when promised goods or services are transferred to clients, in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services.
We are currently evaluating the impact of this guidance. We expect the adoption of this new standard to primarily affect the timing for the recognition of revenues derived from long-term drilling contracts.

65




We are required to apply this new standard beginning January 1, 2018, with earlier adoption permitted. We do not anticipate early adoption of this standard. Two methods of transition are permitted under this standard: the full retrospective method, in which the standard would be applied retrospectively to each prior reporting period presented, subject to certain allowable exceptions; or the modified retrospective method, in which the standard would be applied to all contracts existing as of the date of initial application, with the cumulative effect of applying the standard recognized in beginning retained earnings. We currently anticipate adopting this standard using the modified retrospective method, but we continue to evaluate both transition options available under the standard.
Debt Issuance Costs. On April 7, 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, and that amortization of debt issuance costs be reported as interest expense. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. This ASU requires retrospective adoption and was effective for us beginning with our first quarterly filing in 2016. The adoption of this new standard resulted in reclassifying $7.8 million of debt issuance costs from other long-term assets to long-term debt in the accompanying December 31, 2015 consolidated balance sheet.
Leases.Reclassifications In February 2016, the FASB issued ASU No. 2016-02, Leases, which among other things, requires lessees to recognize substantially all leases on the balance sheet, with expense recognition that is similar to the current lease standard, and aligns the principles of lessor accounting with the principles of the FASB’s new revenue guidance (referenced above). This ASU is effective for us beginning with our first quarterly filing in 2019. We are currently evaluating the potential impact of this guidance and have not yet determined its impact on our financial position and results of operations.
Stock-Based Compensation. In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting, to reduce complexity in accounting standards involving several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for us beginning with our first quarterly filing in 2017. We do not expect that the adoption of this update will have a material effect on our financial position or results of operations.
Credit Losses. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which sets forth an impairment model requiring the measurement of all expected credit losses for financial instruments (including trade receivables) held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This ASU is effective for us beginning with our first quarterly filing in 2020. We do not expect the adoption of this guidance to have a material impact on our financial position or results of operations.
Statement of Cash Flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows, which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The update is intended to reduce the existing diversity in practice, and is effective for us beginning with our first quarterly filing in 2018. We do not expect the adoption of this guidance to have a material impact on our financial position and results of operations.
Reclassifications
Certain amounts in the consolidated financial statements for the prior yearsyear periods have been reclassified to conform to the current year’s presentation.
2.    Revenue from Contracts with Customers
Our production services business segments earn revenues for well servicing, wireline services and coiled tubing services pursuant to master services agreements based on purchase orders or other contractual arrangements with the client. Production services jobs are generally short-term (ranging in duration from several hours to less than 30 days) and are charged at current market rates for the labor, equipment and materials necessary to complete the job. Production services jobs are varied in nature, but typically represent a single performance obligation, either for a particular job, a series of distinct jobs, or a period of time during which we stand ready to provide services as our client needs them. Revenue is recognized for these services over time, as the services are performed.

6661




Our drilling services business segments earn revenues by drilling oil and gas wells for our clients under daywork contracts. Daywork contracts are comprehensive agreements under which we provide a comprehensive service offering, including the drilling rig, crew, supplies and most of the ancillary equipment necessary to operate the rig. Contract modifications that extend the term of a dayrate contract are generally accounted for prospectively as a separate dayrate contract. We account for our services provided under daywork contracts as a single performance obligation comprised of a series of distinct time increments which are satisfied over time. Accordingly, dayrate revenues are recognized in the period during which the services are performed.
With most drilling contracts, we also receive payments contractually designated for the mobilization and demobilization of drilling rigs and other equipment to and from the client’s drill site. Revenues associated with the mobilization and demobilization of our drilling rigs to and from the client’s drill site do not relate to a distinct good or service and are recognized ratably over the related contract term.
The amount of demobilization revenue that we ultimately collect is dependent upon the specific contractual terms, most of which include provisions for reduced (or no) payment for demobilization when, among other things, the contract is renewed or extended with the same client, or when the rig is subsequently contracted with another client prior to the termination of the current contract. Since revenues associated with demobilization activity are typically variable, at each period end, they are estimated at the most likely amount, and constrained when the likelihood of a significant reversal is probable. Any change in the expected amount of demobilization revenue is accounted for with the net cumulative impact of the change in estimate recognized in the period during which the revenue estimate is revised.
The upfront costs that we incur to mobilize the drilling rig to our client’s initial drilling site are capitalized and recognized ratably over the term of the related contract, including any contracted renewal or extension periods, which is our estimate of the period during which we expect to benefit from the cost of mobilizing the rig. Costs associated with the final demobilization at the end of the contract term are expensed when incurred, when the demobilization activity is performed.
We also act as a principal for certain reimbursable services and auxiliary equipment provided by us to our clients, for which we incur costs and earn revenues, many of which are variable, or dependent upon the activity that is actually performed each day under the related contract. Accordingly, reimbursements that we receive for out-of-pocket expenses are recorded as revenues and the out-of-pocket expenses for which they relate are recorded as operating costs during the period to which they relate within the series of distinct time increments.
All of our revenues are recognized net of sales taxes, when applicable.
Trade and Unbilled Accounts Receivable
We record trade accounts receivable at the amount we invoice to our clients. These accounts do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our accounts receivable as of the balance sheet date. We determine the allowance based on the credit worthiness of our clients and general economic conditions. Consequently, an adverse change in those factors could affect our estimate of our allowance for doubtful accounts.
Our production services terms generally provide for payment of invoices in 30 days. Our typical drilling contract provides for payment of invoices in 30 days. We generally do not extend payment terms beyond 30 days and have not extended payment terms beyond 90 days for any of our domestic contracts in the last three fiscal years. We review our allowance for doubtful accounts on a monthly basis. Balances more than 90 days past due are reviewed individually for collectability. We charge off account balances against the allowance after we have exhausted all reasonable means of collection and determined that the potential for recovery is remote. We do not have any off-balance sheet credit exposure related to our clients. The changes in our allowance for doubtful accounts consist of the following (amounts in thousands):
 Year ended December 31,
 2018 2017 2016
Balance at beginning of year$1,224
 $1,678
 $2,254

Balance at end of year$1,423
 $1,224
 $1,678

Our unbilled receivables represent revenues we have recognized in excess of amounts billed on drilling contracts and production services completed. We typically bill our clients at 15-day intervals during the performance of daywork drilling contracts and upon completion of the daywork contract. Our unbilled receivables as of December 31, 2018 and December 31, 2017 were as follows (amounts in thousands):
 December 31, 2018 December 31, 2017
Daywork drilling contracts in progress$24,365
 $15,254
Production services457
 775
 $24,822
 $16,029
Though our typical drilling contract provides for payment of invoices in 30 days, the process for invoicing work performed in our international operations generally lengthens the billing cycle for those operations, which is the primary reason for the increase in unbilled revenues during 2018.
Contract Asset and Liability Balances and Contract Cost Assets
Contract asset and contract liability balances relate to demobilization and mobilization revenues, respectively. Demobilization revenue that we expect to receive is recognized ratably over the related contract term, but invoiced upon completion of the demobilization activity. Mobilization revenue, which is typically collected upon the completion of the initial mobilization activity, is deferred and recognized ratably over the related contract term. Contract asset and liability balances are netted at the contract level, with the net current and noncurrent portions separately classified in our consolidated balance sheets, and referred to herein as “deferred revenues.”
Contract cost assets represent the costs associated with the initial mobilization required in order to fulfill the contract, which are deferred and recognized ratably over the period during which we expect to benefit from the mobilization, or the period during which we expect to satisfy the performance obligations of the related contract. Contract cost assets are presented as either current or noncurrent, according to the duration of the original contract to which it relates, and referred to herein as “deferred costs.”
Our current and noncurrent deferred revenues and costs as of December 31, 2018 and January 1, 2018 were as follows (amounts in thousands):
 December 31, 2018 January 1, 2018
Current deferred revenues$1,722
 $1,287
Current deferred costs1,543
 1,072
    
Noncurrent deferred revenues$437
 $564
Noncurrent deferred costs679
 1,177
The changes in deferred revenue and cost balances during the year ended December 31, 2018 are primarily related to increased deferred mobilization revenue and cost balances for the deployment of five international rigs and one domestic rig under new term contracts in 2018, mostly offset by the amortization of deferred revenues and costs during the period. Amortization of deferred revenues and costs during the years ended December 31, 2018, 2017 and 2016 were as follows (amounts in thousands):
 Year ended December 31,
 2018 2017 2016
Amortization of deferred revenues$2,961
 $2,400
 $1,566
Amortization of deferred costs2,855
 4,953
 2,813
As of December 31, 2018, all but one of our 24 rigs are earning under daywork contracts, 13 of which are domestic term contracts. Our international drilling contracts are cancelable by our clients without penalty, although the contracts require 15 to 30 days notice and payment for demobilization services. The spot contracts for our domestic drilling rigs are also terminable by our client with 30 days notice, but typically do not include a required payment for demobilization services. Revenues associated with the initial mobilization and/or demobilization of drilling rigs under cancelable contracts are deferred and recognized ratably over the anticipated duration of the original contract, which is the period during which we expect our client to benefit from the mobilization of the rig, and represents a separate performance obligation because the payment for mobilization and/or demobilization creates a material right to our client during the cancelable period, for which the transaction price is allocated to the optional goods and services expected to be provided.

63




Remaining Performance Obligations
We have elected to apply the practical expedients in ASC Topic 606 which allow entities to omit disclosure of (i) the transaction price allocated to the remaining performance obligations associated with short-term contracts, and (ii) the estimated variable consideration related to wholly unsatisfied performance obligations, or to distinct future time increments within a series of performance obligations. Therefore, we have not disclosed the remaining amount of fixed mobilization revenue (or estimated future variable demobilization revenue) associated with short-term contracts, and we have not disclosed an estimate of the amount of future variable dayrate drilling revenue. However, the amount of fixed mobilization revenue associated with remaining performance obligations is reflected in the net unamortized balance of deferred mobilization revenues, which is presented in both current and noncurrent portions in our consolidated balance sheet, and discussed in more detail in the section above entitled, Contract Asset and Liability Balances and Contract Cost Assets.
Disaggregation of Revenue
ASC Topic 606 requires disclosure of the disaggregation of revenue into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. We believe the disclosure of revenues by operating segment achieves the objective of this disclosure requirement. See Note 11, Segment Information, for the disaggregation of revenues by operating segment, which reflects the disaggregation of revenues by the type of services provided and by geography (international versus domestic).
Impact of ASC Topic 606 on Financial Statement Line Items and Disclosures
Our revenue recognition pattern under ASC Topic 606 is similar to revenue recognition under the previous accounting guidance, except for: (i) the timing of recognition of demobilization revenues which are estimated and recognized ratably over the term of the related contract under ASC Topic 606, and constrained when appropriate, but were previously not recognized until the activity was performed under previous guidance; (ii) the timing of recognition of mobilization revenues and costs which are recognized over the applicable amortization period beginning when the initial mobilization of the rig is completed, but which, under previous guidance, we recognized over the related contract term beginning when the initial mobilization activity commenced, (iii) the timing of recognition of mobilization costs which are deferred and recognized ratably over the expected period of benefit, but which, under previous guidance, we recognized ratably over the term of the initial contract; and (iv) presentation of mobilization costs which are presented as either current or noncurrent according to the duration of the original contract to which it relates under ASC Topic 606, but which we bifurcated and presented both current and noncurrent portions in separate line items under previous guidance.
These differences have not had a material impact on our consolidated financial position or results of operations as of and during 2018. Additionally, we have determined that any disclosures required by ASC Topic 606 which are not presented herein are either not applicable, or are not material.
Concentration of Clients
We derive a significant portion of our revenue from a limited number of major clients. For the years ended December 31, 2018, 2017 and 2016, our drilling and production services to our top three clients accounted for approximately 20%, 20%, and 26%, respectively, of our revenue.

Capital expenditures during 2018 primarily related to various routine expenditures to maintain our fleets and purchase new support equipment, expansion of our coiled tubing and wireline fleets, capital projects to upgrade and refurbish certain components of our international and domestic drilling rigs and otherbegin construction of one new-build drilling equipment. As of December 31, 2016rig, and 2015, capitalvehicle fleet upgrades in all domestic business segments. Capital expenditures incurred for property and equipment not yet placed in service was $8.7 million and $18.6 million, respectively,during 2017 primarily related to the acquisition of 20 well servicing rigs and expansion of our wireline fleet, upgrades to certain domestic drilling rigs, routine capital expenditures necessary to deploy assets that were previously idle, and other new drilling equipment that was ordered in 2014, but which requires a long lead-time for delivery. This equipment will either be used to construct new drilling rigs or as spare equipment for our AC rig fleet.and trucks. Capital expenditures during 2016 consisted primarily of routine expenditures to maintain our drilling and production services fleets. fleets, and expenditures for equipment ordered in 2014 before the market slowdown.
Capital expenditures during 2015incurred for property and 2014equipment not yet placed in service as of December 31, 2018 primarily related to approximately $8.0 million of costs for the construction of a new-build drilling rig, which is partially being constructed from spare components already in our fivefleet, various refurbishments and upgrades of drilling rigs which began construction during 2014 and were completed in 2015, as well as unit additions to our production services fleets that were orderedequipment, and the purchase of other new ancillary equipment. At December 31, 2017, property and equipment not yet placed in 2014.service primarily related to routine refurbishments on one international drilling rig in preparation for its deployment in 2018, installments on the purchase of three wireline units and one coiled tubing unit, and scheduled refurbishments on drilling and production services equipment.
Gain/Loss on Disposition of Property We recordedrecognized a net gain during the year ended December 31, 2018 of $3.1 million on the disposition of various property and equipment, primarily from the sale of drill pipe and collars, various coiled tubing equipment and fleet disposals, including the sale of five coiled tubing units, twelve wireline units, and two drilling rigs which were designated as held for sale. During 2017, we recognized a net gain of $3.6 million on the disposition of property and equipment, including sales of certain coiled tubing equipment and vehicles, as well as the loss of drill pipe in operation, for which we were reimbursed by the client, and the disposal of three cranes that were damaged. During 2016, we recognized a net gain of $1.9 million on the disposition of property and equipment, primarily forincluding the sale of three SCR drilling rigs for aggregate proceeds of $11.0 million and other drilling equipment, the disposal of excess drill pipe for a gain. The net gains on disposition of assets were partially offset by a loss onand the disposition of damaged property whencomponents from one of our AC drilling rigs sustained damages that resulted in a disposal of the damaged components with an aggregate net carrying value of $4.0 million,rigs.
Assets Held for which we received insurance proceeds of $3.1 million in January 2017 and recognized a net loss on disposal of $0.9 million. Additionally, we retired two domestic SCR rigs at the end of 2016 and placed the remaining two as held for sale at December 31, 2016.
During the year ended December 31, 2015, we recorded a net gain of $4.3 million on the disposition of property and equipment, primarily for the sale of 32 drilling rigs and other drilling equipment which we sold for aggregate proceeds of $53.6 million. In 2014, we sold our trucking assets and our fishing and rental services operations for a net gain of $10.7 million. (See Note 12,Sale Sale of Fishing and Rental Services Operations, for more information.)
As of December 31, 2016,2018, our consolidated balance sheet reflects assets held for sale of $15.1$3.6 million, which primarily represents the fair value of sixtwo domestic mechanical and SCR drilling rigs, andspare drilling equipment 13that would support these rigs and three coiled tubing units. As of December 31, 2017, our consolidated balance sheet reflects assets held for sale of $6.6 million, which primarily represents the fair value of three domestic SCR drilling rigs, one domestic mechanical drilling rig, spare drilling equipment that would support these rigs, two wireline units, 20 older well servicing rigs that will be traded in for 20 new-model rigs inone coiled tubing unit and other spare equipment.

Impairments2016, we recognized impairment charges of $4.4 million, $1.9 million, and $12.8 million, respectively, to reduce the carrying values of assets which were classified as held for sale, to their estimated fair values, based on expected sales prices which are classified as Level 3 inputs as defined by ASC Topic 820, Fair Value Measurements and Disclosures.
WeImpairments — In accordance with ASC Topic 360, Property, Plant and Equipment, we monitor all indicators of potential impairments, and we evaluate for potential impairment of long-lived tangible and intangible assets subject to amortization when indicators of impairment are present. Circumstances that could indicate a potential impairmentpresent, which may include, among other things, significant adverse changes in industry trends economic climate, legal factors, and an adverse action or assessment by a regulator. More specifically, significant adverse changes in industry trends include significant declines in(including revenue rates, utilization rates, oil and natural gas market prices, and industry rig counts.counts). In performing an impairment evaluation, we estimate the future undiscounted net cash flows from the use and eventual disposition of long-lived tangible and intangiblethe assets grouped at the lowest level that independent cash flows can be identified. For our Production Services Segment, weWe perform an impairment evaluation and estimate future undiscounted cash flows for the individualeach of our reporting units (wellseparately, which are our domestic drilling services, international drilling services, well servicing, wireline services and coiled tubing).tubing services segments. For our Drilling Services Segment, we perform an impairment evaluation and estimate future undiscounted cash flows for individual domestic drilling rig assets and for our Colombian drilling rig assets as

a group.If the sum of the estimated future undiscounted net cash flows is less than the carrying amount of the asset group, then we determine the fair value of the asset group. Thegroup, and the amount of an impairment charge iswould be measured as the difference between the carrying amount and the fair value of the assets.
Since late 2014, oil prices have declined significantly resulting in a downturn in our industry, affecting both drilling and production services. As a result, we performed several impairment evaluations during 2014, 2015 and 2016 on our long-lived assets, in accordance with ASC Topic 360, Property, Plant and Equipment, summarized below.
As of December 31, 2014, we owned a total of 31 mechanical and lower horsepower electric drilling rigs. We performed impairment testing on all the mechanical and lower horsepower drilling rigs in our fleet as of December 31, 2014, which resulted in a total impairment of $71 million to reduce the carrying value of these assets to their estimated fair values, based on market appraisals which are considered Level 3 inputs as defined by ASC Topic 820, Fair Value Measurements and Disclosures. During 2015, we sold 28 of these rigs and placed the remaining three as held for sale.
We also performed an impairment test on our drilling rigs in Colombia as of December 31, 2014, at which time we concluded that the sum of the estimated future undiscounted cash flows associated with our Colombian operations was in excess of the carrying amount and concluded that no impairment was present. As the downturn worsened through the first half of 2015, resulting in significantly reduced revenue and utilization rates, and our projections reflected a more delayed recovery than previously anticipated, we performed impairment testing on all the SCR drilling rigs in our fleet, including the eight drilling rigs in Colombia, and our coiled tubing operations as of June 30, 2015. Our analysis at June 30, 2015 indicated that the carrying value of our coiled tubing reporting unit and the carrying value of our domestic pad-capable SCR drilling rigs (those that are equipped with either a walking or skidding system) were recoverable and thus there was no impairment present at June 30, 2015.
However, our analysis at June 30, 2015 indicated that the carrying values of our then six SCR drilling rigs in our domestic fleet which were not pad-capable, and our Colombian assets as a group, exceeded our estimated undiscounted cash flows for these assets. As a result, we recognized impairment charges of $50.2 million to reduce the carrying values of all eight drilling rigs in Colombia and related drilling equipment, $3.6 million to reduce the carrying value of inventory in Colombia, $6.4 million to reduce the carrying value of nonrecoverable prepaid taxes associated with our Colombian operations, and $9.7 million to reduce the carrying values of our then six SCR drilling rigs that were not pad-capable, to their estimated fair values, which were based on market appraisals. Three of these SCR drilling rigs that were not pad-capable were subsequently sold in 2015, one was placed as held for sale at December 31, 2015, and the remaining two were retired in 2016.
Our projected cash flows declined further as compared to our projections made earlier in the year and at September 30, 2015, we again performed impairment testing on our coiled tubing operations and seven drilling rigs, including our domestic pad-capable SCR rigs, and determined that our carrying values in these assets were recoverable but at risk for future impairment. As the downturn persisted through the remainder of 2015, we again performed impairment testing on these assets at December 31, 2015. As a result, we recognized $14.3 million of impairment related to our coiled tubing intangibles, $16.6 million of impairment to reduce the carrying values of our coiled tubing units and equipment to their estimated fair value, based on market appraisals, and $18.6 million to reduce the carrying values of our then six domestic pad-capable SCR rigs to their estimated fair values, which were also based on market appraisals. Of these six domestic SCR rigs, one was subsequently sold in 2015, three were sold in 2016 and the remaining two were placed as held for sale at December 31, 2016.
Business conditions and our projected cash flows for our Colombian operations improved as compared to the projections used for the impairment analysis in 2015, therefore we did not perform any impairment testing on this business in 2016. However, dueDue to lower than anticipated operating results in 2016 and 2017 and a decline in our projected cash flows for the coiled tubing reporting unit, we performed an impairment analysis of our coiled tubing long-lived assets at September 30, 2016 and again at June 30, 2017, which indicated that our projected net undiscounted cash flows associated with the coiled tubing reporting unit were in excess of the net carrying value of the assets at both dates and thus no impairment was present.
DuringDue to adverse factors affecting our well servicing operations, including increased competition and labor shortages in certain well servicing markets, and lower than anticipated utilization, all of which contributed to a decline in our projected cash flows for the years ended December 31, 2016, 2015 and 2014,well servicing reporting unit, we recognizedperformed an impairment chargesanalysis of $11.9 million, $9.9 million, and $2.0 million, respectively, to reducethis reporting unit at September 30, 2018. As a result of this analysis, we concluded that this reporting unit was not at risk of impairment because the sum of the estimated future undiscounted net cash flows for our well servicing reporting unit was significantly in excess of the carrying values of assets which were classified as held for sale,amount.
We used an income approach to their estimatedestimate the fair values, based on expected sales prices. During the year ended December 31, 2016, we also recognized $0.9 million of impairment charges to reduce the carrying value of a portion of steel that is on hand for the construction of drilling rigs, which we no longer believe is likely to be used.

In order to estimate our future undiscounted cash flows from the use and eventual disposition of our drilling assets, we incorporated probabilities of selling these assets in the near term, versus working them at a significantly reduced expected rate of utilization through the end of their remaining useful lives.reporting units. The most significant assumptionsinputs used in our impairment analysis areinclude the expected margin per dayprojected utilization and utilization,pricing of our services, as well as the estimated proceeds upon any future sale or disposal of the assets. We used an income approach to estimate the fair valueassets, all of our coiled tubing services reporting unit. The most significant inputs used in our impairment analysis of our coiled tubing operations include the projected utilization and pricing of our coiled tubing services, which are classified as Level 3 inputs as defined by Accounting Standards Codification (ASC)ASC Topic 820, Fair Value Measurements and Disclosures.
The assumptions we use in the evaluation for impairment are inherently uncertain and require management judgment. Although we believe the assumptions and estimates used in our impairment analysesanalysis are reasonable, and appropriate, different assumptions and estimates could materially impact the analysesanalysis and resulting conclusions. The assumptions used in the impairment evaluationIf commodity prices remain at current levels for long-lived assets are inherently uncertain and require management judgment.These impairment charges are not expected to have an impact on our liquidityextended period of time, or debt covenants; however, they are a reflection of the overall downturn in our industry and decline in our projected future cash flows. Ifif the demand for our services remains at current levels or declines further and any of our assets become or remain idle for an extended amount of time, thenservices decreases below what we are currently projecting, our estimated cash flows may further decrease, and the probability of a near term sale may increase. Ifif any of the foregoing were to occur, we maycould incur additional impairment charges.charges on the related assets.

Senior Notes
In 2014, we issued $300 million of unregistered senior notes at face value, with a coupon interest rate of 6.125% that are due in 2022 (the “Senior Notes”). The Senior Notes were sold at 100% of their face value. After deductions were made for the $6.1 million for underwriters’ fees and other debt offering costs, we received $293.9 million of net proceeds. In order to reduce our overall interest expense and lengthen the overall maturity of our senior indebtedness, during 2014, we redeemed all of our then outstanding $425 million of unregistered senior notes with a coupon interest rate of 9.875% that were issued in 2010 and 2011 and were set to mature in 2018, funded primarily by proceeds from the issuance of Senior Notes in 2014 and additional borrowings under our Revolving Credit Facility, as well as some cash on hand.
The Senior Notes will mature on March 15, 2022 with interest due semi-annually in arrears on March 15 and September 15 of each year. We have the option to redeem the Senior Notes, in whole or in part, at any time on or after March 15, 2017 in each case at the redemption price specified in the Indenture dated March 18, 2014 (the “Indenture”) plus any accrued and unpaid interest and any additional interest (as defined in the Indenture) thereon to the date of redemption. Prior to March 15, 2017, we may also redeem the Senior Notes, in whole or in part, at a “make-whole” redemption price specified in the Indenture, plus any accrued and unpaid interest and any additional interest thereon to the date of redemption. In addition, prior to March 15, 2017, we may, on one or more occasions, redeem up to 35% of the aggregate principal amount of the Senior Notes at a redemption price equal to 106.125% of the principal amount thereof, plus accrued and unpaid interest and additional interest, if any, to the redemption date, with the net cash proceeds of certain equity offerings, provided that at least 65% of the aggregate principal amount of the Senior Notes remains outstanding after the occurrence of such redemption and that the redemption occurs within 120 days of the date of the closing of such equity offering.

71




In accordance with a registration rights agreement with the holders of our Senior Notes, we filed an exchange offer registration statement on Form S-4 with the Securities and Exchange Commission that became effective on October 2, 2014. The exchange offer registration statement enabled the holders of our Senior Notes to exchange their senior notes for publicly registered notes with substantially identical terms. References to the “Senior Notes” herein include the senior notes issued in the exchange offer.
If we experience a change of control (as defined in the Indenture), we will be required to make an offer to each holder of the Senior Notes to repurchase all or any part of the Senior Notes at a purchase price equal to 101% of the principal amount of each Senior Note, plus accrued and unpaid interest, if any, to the date of repurchase. If we engage in certain asset sales, within 365 days of such sale we will be required to use the net cash proceeds from such sale, to the extent we do not reinvest those proceeds in our business, to make an offer to repurchase the Senior Notes at a price equal to 100% of the principal amount of each Senior Note, plus accrued and unpaid interest to the repurchase date.

The Indenture, among other things, limits us and certain of our subsidiaries, subject to certain exceptions, in our ability to:
pay dividends on stock, repurchase stock, redeem subordinated indebtedness or make other restricted payments and investments;
incur, assume or guarantee additional indebtedness or issue preferred or disqualified stock;
create liens on our or their assets;
enter into sale and leaseback transactions;
sell or transfer assets;
borrow, pay dividends, or transfer other assets from certain of our subsidiaries;
consolidate with or merge with or into, or sell all or substantially all of our properties to any other person;
enter into transactions with affiliates; and
enter into new lines of business.
The Senior Notes are not subject to any sinking fund requirements. The Senior Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by certain of our existing domestic subsidiaries and by certain of our future domestic subsidiaries.

We recognized approximately $1.8$1.5 million $1.7 million and $2.1 million of associated amortization during the years ended December 31, 2016, 2015 and 2014, respectively. Additionally, during the years ended December 31, 2016 and 2015, we recognized $0.3 million and $2.2 million, respectively, of loss on extinguishment of debt during 2017 for the write off of the unamortized debt issuance costs associated with the reductionretirement of borrowing capacityour previous credit agreement, which provided for a senior secured revolving credit facility up to an aggregate commitment amount of $150 million and was set to mature in March 2019. In connection with our entry into the Term Loan in November 2017, all indebtedness outstanding under our Revolving Credit Facility.the previous credit facility was repaid, together with related costs and expenses, and the previous credit facility was retired. During 2014,2016, we recognized a$0.3 million of loss on debt extinguishment of $31.2 million fordebt associated with the redemptionamendment of the 2010 and 2011 Senior Notes,our previous credit facility which included redemption premiums of $21.6 million, $4.8 million of net unamortized discount and $4.8 million of unamortized debt issuance costs.resulted in reduced borrowing capacity.
4.5.     Leases
We lease our corporate office facilities in San Antonio, Texas, at a payment escalating from $46,502 per month in January 2017 to $50,246 per month beginning in January 2020. We recognize rent expense on a straight-line basis forand we conduct our corporate office lease. We also lease real estate at 41business operations through 29 other regional offices. Our regional operating locations which are primarily used for fieldtypically include regional offices, and storage and maintenance yards and wepersonnel housing sufficient to support our operations in the area. We lease most of these properties, as well as office and other equipment, under non-cancelable and month to month operating leases, mostmany of which contain renewal options and some of which contain escalation clauses.

As of December 31, 2016,2018, we had $131.4$96.8 million and $9.6 million of deferred tax assets related to domestic and foreign net operating losses, respectively, that are available to reduce future taxable income. In assessing the realizability of our deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.

74




In performing this analysis as of December 31, 20162018 in accordance with ASC Topic 740, Income Taxes, we assessed the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax assets. A significant piece of objective negative evidence evaluated is the projected cumulative loss incurred over the three-year period ended December 31, 2016.during previous years. Such objective negative evidence limits the ability to consider other subjective positive evidence that is subjective, such as projections for taxable income in future years.  Due to the continued downturn in our industry,Because we wereare in a net deferred tax asset position, at the end of 2016, and as a result, we recognizedrecognize a benefit only to the extent that reversals of deferred income tax liabilities are expected to generate taxable income tax expense in each relevant jurisdiction in future periods which would offset our deferred tax assets.
Our domestic federal net operating losses generated through 2017 have a 20 year carryforward period and can be used to offset future domestic taxable income until their expiration, beginning in 2030, with the latest expiration in 2036. However,2037. Losses generated after 2017 have an unlimited carryforward period and are limited in usage to 80% of taxable income (pursuant to the Tax Reform Act mentioned below). The majority of our foreign net operating losses generated through 2016 have an indefinite carryforward period, while losses generated after 2016 have a carryforward period of 12 years. As of December 31, 2018, we have a valuation allowance that fully offsets our foreign and domestic federal deferred tax assets. We also have net operating loss carryforwards in many of the states that we operate in. Most of these are filed on a unitary or combined basis. These states have carryover periods between 5 and 20 years, with most being 15 or 20. We have determined that a valuation allowance should be recorded against a portionsome of the benefit generated in 2016.state benefits through December 31, 2018. The valuation allowance is the primary factor causing our effective tax rate to be significantly lower than the statutory rate of 35%.rate. The amount of the deferred tax asset considered realizable, however, could be adjustedwould increase if estimates of future taxable income are reduced or increased or if objective negative evidence in the form of cumulative losses isare no longer present and additional weight is given to subjective evidence such asin the form of projected future taxable income.
The majority of our foreign net operating losses have an indefinite carryforward period. However, as a result of the conditions leading to the impairment of our assets in Colombia during 2015 and the continued industry downturn, we have a valuation allowance that fully offsets our $21.1 million of foreign deferred tax assets at December 31, 2016.
Additionally, we reversed a valuation allowance of $0.7 million related to a deferred tax asset for a capital loss that expired in 2016.
Deferred income taxes have not been provided on the future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and the respective tax basis of our foreign subsidiary based on the determination that such differences are essentially permanent in duration in that the earnings of the subsidiary is expected to be indefinitely reinvested in foreign operations. As of December 31, 2016, the cumulative undistributed earnings of the subsidiary was a loss of approximately $41.2 million. If earnings were not considered indefinitely reinvested, deferred income taxes would have been recorded after consideration of foreign tax credits. It is not practicable to estimate the amount of additional tax that might be payable on earnings, if distributed.
In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, which requires that deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separately presented as current and noncurrent portions. On December 31, 2015, we elected to early adopt ASU No. 2015-17 prospectively, thus reclassifying $6.8 million of current deferred tax assets to noncurrent on the accompanying consolidated balance sheet.
On December 23, 2014, the Colombian government enacted a tax reform bill that among other things, increased the tax for equality (“CREE”) rate from 9% to 14% in 2015, 15% in 2016, 17% in 2017 and 18% in 2018. Deferred tax assets and liabilities (with the exception of net operating losses) must now be based on the higher combined income tax rate and CREE rate of 39% in 2015, 40% in 2016, 42% in 2017 and 43% in 2018. However, as of December 31, 2015, we recorded a valuation allowance that fully offsets our foreign deferred tax assets relating to net operating losses and other tax benefits. At this time, a new net-worth tax was also enacted for all Colombian entities. The tax is calculated based on an entity’s net equity as of January 1, 2015. The tax expense is recognized when the net-worth tax is assessed, annually from 2015 through 2017. Based on our Colombian operation's net equity, our net-worth tax obligation was $1.2 million for 2015, $0.7 million for 2016 and is expected to be approximately $0.3 million for 2017. The net worth tax is not deductible for income tax purposes.
On December 29, 2016, the Colombian government again enacted a tax reform bill that eliminated the tax for equality (“CREE”), increased the general corporate tax rate from 25% to 40% in 2017, 37% in 2018, 33% in 2019 and created a new 5% dividend tax, among other things. A few other notable provisions include a shorter twelve-year carryforward period for net operating losses generated after 2016, a longer statute of limitations for returns filed after 2016 and annual limits on tax depreciation allowed.
We have no unrecognized tax benefits relating to ASC Topic 740 and no unrecognized tax benefit activity during the year ended December 31, 2016.

2018. We record interest and penalty expense related to income taxes as interest and other expense, respectively. At December 31, 2016,2018, no interest or penalties have been or are required to be accrued. Our open tax years are 20102015 and forward for our federal and most state income tax returns in the United States and 20112013 and forward for our income tax returns in Colombia. Net operating losses generated in years prior to our open years and carried forward are

available for adjustment and subject to the statute of limitation provisions of such year when the net operating losses are utilized.
Recently Enacted Tax Reform
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Reform Act”) was enacted. The legislation significantly changes U.S. tax law by, among other things, permanently reducing the U.S. corporate income tax rate from a maximum of 35% to a flat rate of 21%, repealing the alternative minimum tax (AMT), implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries, limiting the current deductibility of net interest expense in excess of 30% of adjusted taxable income, and limiting net operating losses generated after 2017 to 80% of taxable income.
As a result of the reduction in the U.S. corporate income tax rate, we revalued our ending net deferred tax assets at December 31, 2017 and recognized a $20.1 million tax expense in 2017, which was fully offset by a $20.1 million reduction of the valuation allowance.
Due to the repeal of the AMT, for the year ended December 31, 2017, we reduced the valuation allowance by $5.2 million to remove the effects of AMT on the realizability of our deferred tax assets in future years. In addition, we reversed the valuation allowance on the AMT credit carryforward of $0.2 million that will now be refundable through 2021 and has been reclassified from a deferred tax asset to a noncurrent receivable.
Territorial Tax System — To minimize tax base erosion with a territorial tax system, beginning in 2018, the Tax Reform Act provides for a new global intangible low-taxed income (GILTI) provision. Under the GILTI provision, certain foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets are included in U.S. taxable income. We are now subject to GILTI, and we have elected to treat the GILTI tax as a period expense rather than to provide U.S. deferred taxes on foreign temporary differences that are expected to generate GILTI income when they reverse in future years.
Limitation on Interest Expense Deduction — The new limitation on interest expense resulted in a $11.4 million disallowance for the year ended December 31, 2018; however, this adjustment is offset fully by our net operating loss carry forwards. The disallowed interest has an indefinite carry forward period and any limitations on the utilization of this interest expense carryforward have been factored into our valuation allowance analysis.
Limitation on Future Net Operating Losses Deduction — Net operating losses generated after 2017 are carried forward indefinitely and are limited to 80% of taxable income. Net operating losses generated prior to 2018 continue to be carried forward for 20 years and have no 80% limitation on utilization.
Mandatory Repatriation — The Tax Reform Act provided for a one-time deemed mandatory repatriation of post-1986 undistributed foreign subsidiary earnings and profits through the year ended December 31, 2017. Because we had an accumulated foreign deficit at December 31, 2017, we did not record a tax liability from the mandatory repatriation provision of the Tax Reform Act. We do not intend to distribute earnings in a taxable manner, and therefore, we intend to limit any potential distributions to earnings previously taxed in the U.S., or earnings that would qualify for the 100% dividends received deduction provided for in the Tax Reform Act. As a result, we have not recognized a deferred tax liability on our investment in foreign subsidiaries.
International Tax Reform
On December 28, 2018, the Colombian government enacted a new tax reform bill that decreases the general corporate tax rate from 33% to 30% by 2022, phases out the presumptive tax system by 2021, increases withholding tax rates on payments abroad for various services, and taxes indirect transfers of Colombian assets, among other things. Deferred tax assets and liabilities were adjusted to the new tax rates; however, the adjustments to the valuation allowance fully offset the impact to tax expense.
6.7.Fair Value of Financial Instruments
The FASB’s Accounting Standards Codification (ASC) Topic 820, Fair Value Measurements and Disclosures, defines fair value and provides a hierarchal framework associated with the level of subjectivity used in measuring assets and liabilities at fair value.
At December 31, 2016 and December 31, 2015, our Our financial instruments consist primarily of cash and cash equivalents, trade and other receivables, trade payables, phantom stock unit awards which are described in Note 8, Equity Transactions and Stock-Based Compensation Plans, and long-term debt.

72




The carrying value of cash and cash equivalents, trade and other receivables, and trade payables are considered to be representative of their respective fair values due to the short-term nature of these instruments. At December 31, 2018 and December 31, 2017, the aggregate estimated fair value of our phantom stock unit awards was $5.1 million and $6.1 million, respectively, for which the vested portion recognized as a liability in our consolidated balance sheets at both period ends was $3.6 million. The phantom stock unit awards, and the measurement of fair value for these awards, are described in more detail in Note 9, Equity Transactions and Stock-Based Compensation Plans.
The fair value of our long-term debtSenior Notes is estimated using a discounted cash flow analysis, based on rates that we believe we would currently payrecent observable market prices for similar types ofour debt instruments. This discounted cash flow analysis is based on inputsinstruments, which are defined by ASC Topic 820 as levelLevel 2 inputs. The fair value of our Term Loan is based on estimated market pricing for our debt instrument, which is defined by ASC Topic 820 as using Level 3 inputs which are observable inputs for similar types of debt instruments.unobservable and therefore more likely to be affected by changes in assumptions.

8.9.     Equity Transactions and Stock-Based Compensation Plans
Equity Transactions
In On May 2015,22, 2018, we filed a registration statement that permits us to sell equity or debt in one or more offerings up to a total dollar amount of $300 million. In December 2016, we sold 12,075,000 shares of common stock in a public offering, which resulted in proceeds of approximately $65.4 million, net of underwriting discounts and offering expenses, under the shelf registration statement.$300 million. As of December 31, 2016, $234.62018, the entire $300 million under the shelf registration statement is available for equity or debt offerings, subject to the limitations imposed by our Revolving CreditTerm Loan, ABL Facility and Senior Notes, as well as our Restated Articles of Incorporation which currently limits our issuance of common stock to 100 million shares. In the future, we may consider equity and/or debt offerings, as appropriate, to meet our liquidity needs.Notes.
Stock-based Compensation Plans
We have stock-based award plans that are administered by the Compensation Committee of our Board of Directors, which selects persons eligible to receive awards and determines the number, terms, conditions and other provisions of the awards.
At December 31, 20162018, the total shares available for future grants to employees and directors under existing plans were 4,603,268,2,390,057, which excludes awards we grant in the form of phantom stock unit awards which are expected to be paid in cash. For more information about the shares available under existing plans, see Part III, Item 12, Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters, of this Annual Report on Form 10-K. In January 2017,2019, our Board of Directors approved the grant of the following awards, each with a three-year vesting term:awards:

We grant stock option and restricted stock awards with vesting based on time of service conditions. We grant restricted stock unit awards with vesting based on time of service conditions, and in certain cases, subject to performance and market conditions. In 2016, we grantedWe grant phantom stock unit awards with vesting based on time of service, performance and market conditions, which wereare classified as liability awards under ASC Topic 718, Compensation—Stock Compensation since we expect to settle the awards in cash when they become vested.
We recognize compensation cost for stock option, restricted stock, restricted stock unit, and phantom stock unitour stock-based compensation awards based on the fair value estimated in accordance with ASC Topic 718.718, Compensation—Stock Compensation, and we recognize forfeitures when they occur. For our awards with graded vesting, we recognize compensation expense on a straight-line basis over the service period for each separately vesting portion of the award as if the award was, in substance, multiple awards.

Stock Options
We grant stock option awards which generally become exercisable over a three-year period and expire ten years after the date of grant. Our stock-based compensation plans require that all stock option awards have an exercise price that is not less than the fair market value of our common stock on the date of grant. We issue shares of our common stock when vested stock option awards are exercised.
We estimate the fair value of each option grant on the date of grant using a Black-Scholes option pricing model. There were no stock options granted during the year ended December 31, 2018. The following table summarizes the assumptions used in the Black-Scholes option pricing model based on a weighted-average calculation for the options granted during the years ended December 31, 2016, 20152017 and 20142016:

The assumptions used in the Black-Scholes option pricing model are based on multiple factors, including historical exercise patterns of homogeneous groups with respect to exercise and post-vesting employment termination behaviors, expected future exercising patterns for these same homogeneous groups and volatility of our stock price. As we have not declared dividends since we became a public company, we did not use a dividend yield. In each case, the actual value that will be realized, if any, will depend on the future performance of our common stock and overall stock market conditions. There is no assurance the value an optionee actually realizes will be at or near the value we have estimated using the Black-Scholes options-pricing model.

Restricted Stock
We grant restricted stock awards that vest over a one-year period with a fair value based on the closing price of our common stock on the date of the grant. When restricted stock awards are granted, or when restricted stock unit awards are converted to restricted stock, shares of our common stock are considered issued, but subject to certain restrictions.

Restricted Stock Units
We grant restricted stock unit awards with vesting based on time of service conditions only (“time-based RSUs”), and we grant restricted stock unit awards with vesting based on time of service, which are also subject to performance and market conditions (“performance-based RSUs”). Shares of our common stock are issued to recipients of restricted stock units only when they have satisfied the applicable vesting conditions. Our time-based RSUs generally vest over a three-year period, with fair values based on the closing price of our common stock on the date of grant. Our performance-based RSUs generally cliff vest after 39 months from the date of grant and are granted at a target number of issuable shares, for which the final number of shares of common stock is adjusted based on our actual achievement levels that are measured against predetermined performance conditions. The number of shares of common stock awarded will be based upon the Company’s achievement in certain performance conditions, as compared to a predefined peer group, over the performance period, generally three years.
Approximately half of the performance-based RSUs outstanding are subject to a market condition based on relative total shareholder return, as compared to that of our predetermined peer group, and therefore the fair value of these awards is measured using a Monte Carlo simulation model. Compensation expense for equity awards with a market condition is reduced only for estimatedactual forfeitures; no adjustment to expense is otherwise made, regardless of the number of shares issued. The remaining performance-based RSUs are subject to performance conditions, based on our EBITDA and EBITDA return on capital employed, relative to our predetermined peer group, and therefore the fair value is based on the closing price of our common stock on the date of grant, applied to the estimated number of shares that will be awarded. Compensation expense ultimately recognized for awards with performance conditions will be equal to the fair value of the restricted stock unit award based on the actual outcome of the service and performance conditions.

79




In April 2016,2018, we determined that 72%106% of the target number of shares granted during 20132015 were actually earned based on the Company’s achievement of the performance measures as described above, resulting in a reductionan increase of 75,75725,807 shares being issued. As of December 31, 20162018, we estimate that our actualthe achievement level for our outstanding performance-based RSUs granted in 2017 will be approximately 100% of the predetermined performance conditions.

Phantom Stock Unit Awards
In 2016 and 2018, we granted 1,268,068 and 1,188,216 phantom stock unit awards thatwith weighted-average grant-date fair values of $1.35 and $3.06 per share, respectively. These awards cliff-vest after 39 months from the date of grant, with vesting based on time of service, performance and market conditions. The number of units ultimately awarded will be based upon the Company’s achievement in certain performance conditions, as compared to a predefined peer group, over the respective three-year performance period,periods, and each unit awarded will entitle the employee to a cash payment equal to the stock price of our common stock on the date of vesting, subject to a maximum of $8.08 and $9.66 (which is four and three times the grant date stock priceprice), respectively.
The fair value of these awards is measured using inputs that are defined as Level 3 inputs under ASC Topic 820, Fair Value Measurements and Disclosures. Half of the 2016 phantom stock unit awards are subject to a market condition based on relative total shareholder return, and therefore the datefair values of grant.these awards are measured using a Monte Carlo simulation model, which incorporates the estimate of our relative total shareholder return achievement level. The remaining 2016 phantom stock unit awards are subject to performance conditions, based on our relative EBITDA and EBITDA return on capital employed, and the fair values of these awards are measured using a Black-Scholes pricing model. The 2018 phantom stock unit awards will vest based upon our relative total shareholder return and relative EBITDA return on capital, both of which are subject to market conditions, and therefore, the fair value of these awards is measured using a Monte Carlo simulation model which generates a fair value that incorporates the relative estimated achievement levels. As of December 31, 2018, we estimate the achievement levels for our outstanding 2016 and 2018 phantom stock unit awards to be 175% and 100%, respectively.
These awards are classified as liability awards under ASC Topic 718, Compensation—Stock Compensation, because we expect to settle the awards in cash when they vest, and are remeasured at fair value at the end of each reporting period until they vest. Approximately halfThe change in fair value is recognized as a current period compensation expense in our consolidated statements of operations.Therefore, changes in the inputs used to measure fair value can result in volatility in our compensation expense. This volatility increases as the phantom stock unit awards granted are subject toapproach the vesting date. We estimate that a hypothetical increase of $1 in the market condition based on relative total shareholder return, as compared to thatprice of our predetermined peer group, and thereforecommon stock, which was $1.23 as of December 31, 2018, if all other inputs were unchanged, would result in an increase in cumulative compensation expense of $0.4 million, which represents the hypothetical increase in fair value of these awards is measured using a Monte Carlo simulation model. The remainingthe liability for the 2018 phantom stock unit awards are subject to performance conditions, based on our EBITDA and return on capital employed, relative to our predetermined peer group, and the fair value of these awards is measured using a Black-Scholes pricing model.

9.10.     Employee Benefit Plans and Insurance
We maintain a 401(k) retirement plan for our eligible employees. Under this plan, we may make a matching contribution, on a discretionary basis, equal to a percentage of each eligible employee’s annual contribution, which we determine annually. Our matching contributions for the years ended December 31, 2018, 2017 and 2016 2015were $4.6 million, $3.1 million and 2014 were $0.3 million, $4.2 million and $6.4 million, respectively. Effective February 1, 2016, inIn an effort to reduce costs in response to the downturn in our industry, we suspended matching contributions. This benefit was reinstated incontributions from February 2016 to January 2017.
We use a combination of self-insurance and third-party insurance for various types of coverage. We are self-insured for up to $500,000 per incident for all workers’ compensation claims submitted by employees for on-the-job injuries. We accrue our workers’ compensation claim cost estimates using an actuarial calculation that is based on industry and our company’s historical claim development data, and we accrue the cost of administrative services associated with claims processing. We maintain a self-insurance program for major medical and hospitalization coverage for employees and their dependents, which is partially funded by employee payroll deductions. We have a maximum health insurance liability of $200,000 per covered individual per year, while amounts in excess of this maximum are covered under a separate policy provided by an insurance company. We have provided for reported claims costs as well as incurred but not reported medical costs in the accompanying consolidated balance sheets. We have a maximum liability of $200,000 per covered individual per year. Amounts in excess of the stated maximum are covered under a separate policy provided by an insurance company. Accrued insurance premiums and deductibles at December 31, 2016 and 2015 include $2.0 million and $2.4 million, respectively, for our estimate of incurred but unpaid costs related to the self-insurance portion of our health insurance.
We are self-insured for up to $500,000 per incident for all workers’ compensation claims submitted by employees for on-the-job injuries. We accrue our workers’ compensation claim cost estimates based on historical claims development data and we accrue the cost of administrative services associated with claims processing. We also have a deductible of $250,000$250,000 per occurrence under both our general liability insurance and auto liability insurance.
Accrued insurance premiums and deductibles at December 31, 2016 and 2015 include $4.4 million and $5.5 million, respectively, forrelated to our estimate of costs relative to the self-insured portion of costs associated with our health, workers’ compensation, general liability and auto liability insurance. insurance are as follows:

Based upon our past experience, management believes that we have adequately provided for potential losses. However, future multiple occurrences of serious injuries to employees could have a material adverse effect on our financial position and results of operations.
Our insurance recoveries receivables and our accrued liability for insurance claims and settlements represent our estimate of claims in excess of our deductible, which are covered and managed by our third-party insurance providers, some of which may ultimately be settled by the insurance provider in the long-term. These are presented in our consolidated balance sheets as current due to the uncertainty in the timing of reporting and payment of claims.

Commitments and Contingencies
In connection with our operations in Colombia, our foreign subsidiaries have obtainedroutinely obtain bonds for bidding on drilling contracts, performing under drilling contracts, and remitting customs and importation duties. We have guaranteed payments of $36.350.9 million relating to our performance under these bonds as of December 31, 2016.2018. Based on historical experience and information currently available, we believe the likelihood of demand for payment under these bonds and guarantees is remote.
We have received an increased number of notices in recent years from state taxing authorities for audits of sales and use tax obligations. We are currently undergoing sales and use tax audits for multi-year periods and we are working to resolve all relevant issues.periods. As of both December 31, 20162018 and December 31, 2015,2017, our accrued liability was $0.6$1.7 million and $1.2 million, respectively, based on our estimate of the sales and use tax obligations that are expected to result from these audits. Due to the inherent uncertainty of the audit process, we believe that it is reasonably possible that we may incur additional tax assessments with respect to one or more of the audits in excess of the amount accrued. We believe that such an outcome would not have a material adverse effect on our results of operations or financial position. Because certain of these audits are in a preliminary stage, an estimate of the possible loss or range of loss from an adverse result in all or substantially all of these cases cannot reasonably be made.
Due to the nature of our business, we are, from time to time, involved in litigation or subject to disputes or claims related to our business activities, including workers’ compensation claims and employment-related disputes. Legal costs relating to these matters are expensed as incurred. In the opinion of our management, none of the pending litigation, disputes or claims against us will have a material adverse effect on our financial condition, results of operations or cash flow from operations.

12.     Sale of Fishing and Rental Services Operations
On September 17, 2014, we entered into an asset sales agreement with Basic Energy Services L.P. (“Basic”) for the sale of our fishing and rental services (“F&R”) operations for total consideration of $16.1 million, which consisted of $15.1 million of cash received at closing and $1.0 million which was held in escrow for a period of 180 days. Under the terms of the sales agreement, Basic purchased two real estate locations and all F&R tools and equipment for which we had a total net book value of $4.3 million at the date of sale. We recognized a $10.7 million gain on the sale of our F&R operations, which net of income taxes was $6.6 million. Cash proceeds from the sale were used to repay long-term debt obligations.
For the nine months ended September 30, 2014, F&R operations represented approximately 1% of our consolidated revenues and approximately 1% of our consolidated pretax income. Total assets for F&R at the date of sale represented less than 1% of our total assets at September 30, 2014. The sale of the F&R operations did not represent a strategic shift for our company, did not have a significant effect on our operating results, and did not represent discontinued operations based on the criteria of ASU No. 2014-08, Discontinued Operations. Statement of operations information for the F&R operations is as follows for the year ended December 31, 2014 (amounts in thousands):

Guarantor/Non-Guarantor Condensed Consolidating Financial Statements
Our Senior Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by all existing wholly100% owned domestic subsidiaries, except for Pioneer Services Holdings, LLC. The subsidiaries that generally operate our non-U.S. business concentrated in Colombia do not guarantee our Senior Notes. The non-guarantor subsidiaries do not have any payment obligations under the Senior Notes, the guarantees or the Indenture.
In the event of a bankruptcy, liquidation or reorganization of any non-guarantor subsidiary, such non-guarantor subsidiary will pay the holders of its debt and other liabilities, including its trade creditors, before it will be able to distribute any of its assets to us. In the future, any non-U.S. subsidiaries, immaterial subsidiaries and subsidiaries that we designate as unrestricted subsidiaries under the Indenture will not guarantee the Senior Notes. As of December 31, 20162018, there were no restrictions on the ability of subsidiary guarantors to transfer funds to the parent company.
As a result of the guarantee arrangements, we are presenting the following condensed consolidating balance sheets, statements of operations and statements of cash flows of the issuer, the guarantor subsidiaries and the non-guarantor subsidiaries.

ItemITEM 9.Changes in and Disagreements With Accountants on Accounting and Financial DisclosureCHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
Not applicable.
ItemITEM 9A.Controls and ProceduresCONTROLS AND PROCEDURES
In accordance with Exchange Act Rules 13a-15 and 15d-15, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 20162018, to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and (2) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
In the ordinary course of business, we may make changes to our systems and processes to improve controls and increase efficiency, and make changes to our internal controls over financial reporting in order to ensure that we maintain an effective internal control environment.
We are nearing the completion of our implementation process for the adoption of ASU No. 2016-02, Leases, and its related amendments, which we discuss more fully in Note 1, Organization and Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K. During this implementation and upon adoption of the new standard, we expect certain changes to be necessary affecting our internal control over financial reporting, the most significant of which relate to the implementation of a new lease accounting system and modifications to the related payment and accounting processes.
There has been no change in our internal control over financial reporting that occurred during the three months ended December 31, 20162018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Management’s Annual Report on Internal Control Over Financial Reporting
The management of Pioneer Energy Services Corp. is responsible for establishing and maintaining adequate internal control over financial reporting. Pioneer Energy Services Corp.’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 Pioneer Energy Services Corp. 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.
Pioneer Energy Services Corp.’s management assessed the effectiveness of Pioneer Energy Services Corp.’s internal control over financial reporting as of December 31, 20162018. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). Based on our assessment we have concluded that, as of December 31, 20162018, Pioneer Energy Services Corp.’s internal control over financial reporting was effective based on those criteria.
KPMG LLP, the independent registered public accounting firm that audited the consolidated financial statements of Pioneer Energy Services Corp. included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of Pioneer Energy Services Corp.’s internal control over financial reporting as of December 31, 20162018. This report is included in Item 8, Financial Statements and Supplementary Data.

It does not include awards we grant in the form of phantom stock unit awards which are expected to be paid in cash.
(2)The weighted-average exercise price does not take into account the shares issuable upon vesting of outstanding awards of restricted stock units, which have no exercise price.

From January 1, 2017 to February 17, 2017, we granted options to purchase 268,185 shares of our common stock and restricted stock unit awards covering 630,197 shares of our common stock to 82 employees and executive officers. Applying the share counting rules under the 2007 Incentive Plan, these grants reduce the total number of shares available for issuance under the 2007 Incentive Plan by 1,137,134. Factoring in forfeitures that have occurred from January 1, 2017 to February 17, 2017, this leaves 3,466,134 shares available for issuance as of February 17, 2017. Pursuant to the terms of the 2007 Incentive Plan, if full value awards are issued, the fungible share pool approach under the 2007 Incentive Plan would deplete the shares available for issuance at a rate of 1.38 shares per share actually covered by an award.
