 Forward Looking Statements
This Annual Report on Form 10-K contains “forward-looking statements,” as contemplated by the Private Securities Litigation Reform Act of 1995, in which the Company discusses factors it believes may affect its performance in the future. Forward-looking statements are all statements other than historical facts, such as statements regarding assumptions, expectations, beliefs and projections about future events or conditions. You can generally identify forward-looking statements by the appearance in such a statement of words like “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “remain,” “should,” “will,” or other comparable words or the negative of such words. The accuracy of the Company’s assumptions, expectations, beliefs and projections depends on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. The Company gives no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. The Company’s actual future results might differ from the forward-looking statements made in this Annual Report on Form 10-K for a variety of reasons, including sustained low or further declines in oil and natural gas prices; continued weakness in demand for the Company’s services through and beyond the maturity of any of the Company's long-term debt; unplanned customer suspensions, cancellations, rate reductions or non-renewals of vessel charters, vessel management contracts, or failures to finalize commitments to charter or manage vessels; sustained or further reductions in capital spending budgets by customers; the inability to accurately predict vessel utilization levels and dayrates; fewer than anticipated deepwater and ultra-deepwater drilling units operating in the GoM or other regions where the Company operates; the effect of inconsistency by the United States government in the pace of issuing drilling permits and plan approvals in the GoM or other drilling regions; the Company’s inability to successfully complete the remainder of its current vessel newbuild program on-time and on-budget, which involves the construction and integration of highly complex vessels and systems; the inability to successfully market the vessels that the Company owns, is constructing or might acquire; the government's cancellation or non-renewal of the management, operations and maintenance contracts for vessels; an oil spill or other significant event in the United States or another offshore drilling region that could have a broad impact on deepwater and other offshore energy exploration and production activities, such as the suspension of activities or significant regulatory responses; the imposition of laws or regulations that result in reduced exploration and production activities or that increase the Company’s operating costs or operating requirements; environmental litigation that impacts customer plans or projects; disputes with customers; bureaucratic, administrative or operating barriers that delay vessels in foreign markets from going on-hire or result in contractual penalties or deductions imposed by foreign customers; industry risks; the impact stemming from the reduction of Petrobras' announced plans for or administrative barriers to exploration and production activities in Brazil; recent disruption in Mexican offshore activities; age or other restrictions imposed on our vessels by customers; unanticipated difficulty in effectively competing in or operating in international markets; less than anticipated subsea infrastructure and field development demand in the GoM and other markets affecting our MPSVs; sustained vessel over capacity for existing demand levels in the markets in which the Company competes; economic and geopolitical risks; weather-related risks; upon a return to improved operating conditions, the shortage of or the inability to attract and retain qualified personnel, when needed, including vessel personnel for active vessels or vessels the Company may reactivate or acquire; any success in unionizing the Company's U.S. fleet personnel; regulatory risks; the repeal or administrative weakening of the Jones Act or adverse changes in the interpretation of the Jones Act related to the U.S. citizenship qualification; drydocking delays and cost overruns and related risks; vessel accidents, pollution incidents or other events resulting in lost revenue, fines, penalties or other expenses that are unrecoverable from insurance policies or other third parties; unexpected litigation and insurance expenses; fluctuations in foreign currency valuations compared to the U.S. dollar and risks associated with expanded foreign operations, such as non-compliance with or the unanticipated effect of tax laws, customs laws, immigration laws, or other legislation that result in higher than anticipated tax rates or other costs; the inability to repatriate foreign-sourced earnings and profits; or the inability of the Company to refinance or otherwise retire funded debt obligations that come

ii


due in 2019, 2020 and 2021. In addition, the Company’s future results may be impacted by adverse economic conditions, such as inflation, deflation, or lack of liquidity in the capital markets, that may negatively affect it or parties with whom it does business resulting in their non-payment or inability to perform obligations owed to the Company, such as the failure of customers to fulfill their contractual obligations or the failure by individual banks to provide funding under the Company’s credit agreement, if required. Further, the Company can give no assurance regarding when and to what extent it will effect common stock or note repurchases. Should one or more of the foregoing risks or uncertainties materialize in a way that negatively impacts the Company, or should the Company’s underlying assumptions prove incorrect, the Company’s actual results may vary materially from those anticipated in its forward-looking statements, and its business, financial condition and results of operations could be materially and adversely affected and, if sufficiently severe, could result in noncompliance with certain covenants of the Company's currently undrawn revolving credit facility. Additional factors that you should consider are set forth in detail in the “Risk Factors” section of this Annual Report on Form 10-K as well as other filings the Company has made and will make with the Securities and Exchange Commission which, after their filing, can be found on the Company’s website, www.hornbeckoffshore.com.
The Company makes references to certain industry-related terms in this Annual Report on Form 10-K. A glossary and definitions of such terms can be found in Item 9B—Other Information on page 47.

PART I
ITEM 1—Business
COMPANY OVERVIEW
Hornbeck Offshore Services, Inc. was incorporated under the laws of the State of Delaware in 1997. In this Annual Report on Form 10-K, references to “Company,” “we,” “us,” “our” or like terms refer to Hornbeck Offshore Services, Inc. and its subsidiaries, except as otherwise indicated. Hornbeck Offshore Services, Inc. is a leading provider of marine transportation, subsea installation and accommodation support services to exploration and production, oilfield service, offshore construction and U.S. military customers. Since our establishment, we have primarily focused on providing innovative technologically advanced marine solutions to meet the evolving needs of the deepwater and ultra-deepwater energy industry in domestic and select foreign locations. Throughout our history, we have expanded our fleet of vessels primarily through a series of new vessel construction programs, as well as through acquisitions of existing vessels. We maintain our headquarters at 103 Northpark Boulevard, Suite 300, Covington, Louisiana, 70433; our telephone number is (985) 727-2000.
We own and operate one of the youngest and largest fleets of U.S.-flagged, new generation OSVs and MPSVs. In late 2011, we commenced our fifth OSV newbuild program, which also includes the construction of MPSVs. Since that time, we have grown our new generation fleet from 51 OSVs and four MPSVs to 62 OSVs and eight MPSVs, after accounting for the sale of five OSVs in 2014 and 2015. Upon completion of the last two vessels currently contracted to be delivered under this newbuild program in 2018, our expected fleet will be comprised of 62 OSVs and ten MPSVs. Together, these vessels support the deep-well, deepwater and ultra-deepwater activities of the offshore oil and gas industry. Such activities include oil and gas exploration, field development, production, construction, installation, IRM, well-stimulation and other enhanced oil recovery activities. We have also developed a specialized application of our new generation OSVs for use by the U.S. military. Our new generation OSVs and MPSVs have enhanced capabilities that allow us to more effectively support the premium drilling and installation equipment and facilities required for the offshore deep-well, deepwater and ultra-deepwater energy industry. We are one of the top two operators of domestic high-spec new generation OSVs and MPSVs and one of the top four operators of such equipment worldwide, based on DWT. Our fleet is among the youngest in the industry, with a weighted-average age, based on DWT, of eight years.
While we have historically operated our vessels predominately in the U.S. GoM, we have diversified our market presence and now operate in three core geographic markets: the GoM, Mexico and Brazil. In addition to our core markets, we frequently operate in other foreign regions on a project or term charter basis. We have recently operated in the Middle East, the Mediterranean Sea, the Black Sea and Latin America, including Nicaragua, Guyana, Trinidad and Argentina. We have further diversified by providing specialized vessel solutions to non-oilfield customers, such as the United States military as well as oceanographic research and other customers that utilize sophisticated marine platforms in their operations. In addition, we have provided vessel management services for other vessel owners, such as crewing, daily operational management and maintenance activities. We also operate a shore-base support facility located in Port Fourchon, Louisiana. See "Item 2-Properties" for a listing of our shoreside support facilities.
Although all of our vessels are physically capable of operating in both domestic and international waters, approximately 85% are qualified under Section 27 of the Merchant Marine Act of 1920, as amended, or the Jones Act, to engage in the U.S. coastwise trade. The two remaining vessels being constructed under our fifth OSV newbuild program will be eligible for Jones Act coastwise trading privileges. Foreign owned, flagged, built or crewed vessels are restricted in their ability to conduct U.S. coastwise trade and are typically excluded from such trade in the GoM. Of the public company OSV peer group, we own the largest fleet of Jones Act-qualified, new generation OSVs and MPSVs, which we believe offers us a competitive advantage in the GoM. From time to time, we may elect to reflag certain of our vessels to the flag of another nation. Since 2009, we have reflagged seven Jones Act-qualified OSVs to Mexican and other flags, including one under Brazilian registry. Once a Jones Act-qualified vessel is reflagged or a new vessel is foreign flagged, it permanently loses the right to engage in U.S. coastwise trade.
We intend to continue our efforts through up cycles and down cycles to maximize stockholder value through our long-term return-oriented growth strategy. We will, as opportunities arise, acquire or construct additional vessels, as well as divest certain assets that we consider to be non-core or otherwise not in line with our long-term strategy or prevailing industry trends.

DESCRIPTION OF OUR BUSINESS
The Deepwater Offshore Energy Industry
The modern quest to explore for and produce energy resources located offshore began in the 1940’s. While these offshore operations began in shallow waters, relatively close to shore, technological advances have permitted them to migrate to ever deeper waters and well depths. Until the late 1970's, most offshore activity was technologically and logistically restricted to that which was accessible on the continental shelf, or waters of up to about 500 feet of depth. Since that time, a number of advances have opened drilling regions in deepwater. The initial push into deeper waters was facilitated through the development of “floating” drilling units that could be positioned over a drilling site without being fixed to the seafloor. Petrobras pioneered these techniques in Brazil beginning in the late 1970’s as it lacked an accessible “shallow water” continental shelf. The first deepwater project in the United States Gulf of Mexico was completed in 1993 in nearly 3,000 feet of water by Shell Oil Company. That Shell facility produced a then unheard of 46,000 barrels per day from a reservoir tapped at 25,000 feet. Today, exploration and production activities have pushed into the ultra-deepwater, where wells are routinely drilled in water depths of more than 8,000 feet, the deepest having been drilled in approximately 10,000 feet of water.
In addition to the ability to operate in very deepwater, technological advances have also allowed hydrocarbon resources to be detected, drilled for and produced at extreme well depths. “Pre-salt” discoveries in Brazil are being drilled and produced in waters exceeding 5,000 feet and at well depths of more than 35,000 feet. In 2014, Chevron announced first oil from its Jack/St. Malo facility in the GoM, which is expected to produce previously undetectable lower tertiary hydrocarbons at a rate of 94,000 barrels per day from deposits more than 20,000 feet below the seabed situated in 7,000 feet of water. In addition to contending with extreme deepwater and deep well depths, these projects present challenges involving high temperatures and pressures within reservoirs and the associated difficulties of safely bringing those resources to the surface and then transporting them to shoreside locations. Despite these challenges, today deepwater production accounts for approximately 80% percent of all offshore production in the United States. The GoM production is expected to account for 18% and 21% of total forecast U.S. crude oil production in 2016 and 2017.
Deepwater Regions
The energy industry has had success in many deepwater regions throughout the world. Deepwater drilling efforts are underway in the Mediterranean Sea, the Indian Ocean and Asia. However, the so-called “golden triangle” of deepwater activity is comprised of deposits found offshore West Africa, the Eastern coast of South America - dominated by Brazil and more recently, Guyana - and the GoM. Our core markets are the U.S. GoM, Mexico and Brazil.
As large international oil companies were pushed out of participating in many regions of the world by national oil companies intent upon retaining for themselves the economic benefits of national exploitation, the deepwater GoM grew in significance. The deepwater GoM is among the most abundant hydrocarbon regions in the world. Political stability in the United States and accessibility of deepwater lease blocks allows major oil companies to plan, execute and finance the significant long-term commitments that deepwater success requires. While the scale and complexity associated with deepwater projects is considerable, the significant size of the resource discoveries allows companies to replenish reserves on a large scale from relatively few projects. Unlike most on-shore exploration and production projects, deepwater projects require long-lead times to plan and execute, but also enjoy long production lives once online. For instance, the first exploratory wells at the Jack/St. Malo fields were drilled in 2003 and 2004 and first oil was not produced until 2014. Now online, Chevron projects that the Jack/St. Malo fields are expected to produce an estimated 500 million oil equivalent barrels over 30 years. Consequently, short term fluctuations in oil and gas prices typically do not have the same impact on sanctioned deepwater projects as such fluctuations may have on other on-shore and continental shelf projects. As a result of the severity and length of current on-going commodity price declines, some previously sanctioned deepwater projects have, nevertheless, been deferred and the pace of newly sanctioned projects in the deepwater GoM has slowed considerably since 2015.
Emerging opportunities for the deepwater offshore energy industry are presented by recent changes in Mexico and Brazil, two of our core markets, which have both recently expanded access to their deepwater regions to foreign operators. In December 2013, the Mexican congress ended PEMEX's 75 year-old monopoly on drilling activities in Mexico and voted in favor of allowing the government to grant contracts and licenses for exploration and production of oil and gas to foreign firms, which previously had been prohibited under Mexico’s constitution. During 2015, Mexico hosted the first two auctions for offshore oil and natural gas blocks allowed by the energy reforms. Drilling activities pursuant to these auctions will commence in 2017. In December 2016, Mexico conducted its first ever deepwater auctions, which drew bids from several major integrated oil companies on 10 deepwater opportunities. Eight blocks were awarded to

2


companies including Exxon, CNOOC, Murphy Oil Company, Total, BHP and Chevron. Mexican officials have indicated their intention to proceed with additional deepwater auctions in 2017 and 2018.
Brazil, through its state-owned national oil company, Petrobras, has been a pioneer in deepwater drilling and remains a dominant player in the global deepwater energy industry. Petrobras claims approximately 13.3 billion barrels of proven deepwater and ultra-deepwater resources, the vast majority of which are located in pre-salt formations, which were the driving force behind an ambitious national plan to dramatically increase production by 2021 to 3.4 million barrels per day. These plans were sidelined by declines in the price of oil combined with a wide reaching corruption probe involving Petobras. In light of these difficulties being experienced by Petrobras, in 2016, the Brazilian Congress determined to re-open the vast Brazilian pre-salt regions to foreign operators.
The Subsea Oilfield
Deepwater successes have driven further innovation around the infrastructure required to produce and transport ashore the abundant resources that have been discovered. In shallower regions, once hydrocarbons are discovered, they are typically produced by installing a fixed platform over the well site onto which are installed all of the equipment and infrastructure necessary to produce the hydrocarbons and move them ashore through pipelines. Platforms also provide a locale from which well maintenance and similar activities can be performed. The size, pressures, temperatures and water depths of deepwater hydrocarbon deposits require enormous amounts of infrastructure to develop, produce and maintain their wells. These challenges have pushed the development of technologies to allow infrastructure to be placed directly onto the seafloor, as opposed to a fixed platform. The process of building out this subsea oilfield requires the use of vessels to transport infrastructure to location, install infrastructure to subsea points and inspect, repair and maintain it all over the multi-decade life of the field. When hydrocarbons are brought to the surface, they are brought from multiple subsea locations through pipelines to a single deepwater floating "top-side" production facility. These "top-side" production facilities take years to design, engineer, transport, install and, often, cost billions of dollars and represent a significant source of demand for vessel services during their installation and commissioning. More recently, deepwater producers have capitalized on their existing deepwater infrastructure to gain efficiencies through the use of so-called "tie-backs". A tie-back allows a deepwater well to be produced without having to install a new top-side facility by "tying the well back" to an existing top-side facility accessible to the well location. Tie-backs require the installation of subsea infrastructure to connect the well to the remote "top-side" facility.

OSVs
OSVs primarily serve exploratory and developmental drilling rigs and production facilities and support offshore and subsea construction, installation, IRM and decommissioning activities. OSVs differ from other ships primarily due to their cargo-carrying flexibility and capacity. In addition to transporting deck cargo, such as pipe or drummed material and equipment, OSVs also transport liquid mud, potable and drilling water, diesel fuel, dry bulk cement and personnel between shore bases and offshore rigs and production facilities. Deepwater environments require OSVs with capabilities that allow them to more effectively support drilling and related subsea construction projects that occur far from shore, in deepwater and increasingly at extreme well depths. In order to best serve these projects, we have designed our various classes of new generation vessels in a manner that seeks to maximize their liquid mud and dry bulk cement capacities, as well as their larger areas of open deck space. Deepwater operations also require vessels having dynamic positioning, or anchorless station-keeping capability, driven primarily by safety concerns that preclude vessels from physically mooring to floating deepwater installations. DP systems have experienced steady increases in technology over time with the highest DP rating currently being DP-3. The number following the DP notation generally indicates the degree of redundancy built into the vessel’s systems and the range of usefulness of the vessel in deepwater construction and subsea operations. Higher numbers represent greater DP capabilities. Today, deepwater drilling operations in the GoM overwhelmingly prefer a DP-2 notation and a vessel with 2,500 DWT capacity or greater. We consider these vessels to be high-spec new generation OSVs. Currently, 54 of our vessels are DP-2 and two are DP-3. The two remaining MPSVs contracted to be constructed under our fifth OSV newbuild program are expected to be DP-2. Ultra-deepwater projects, which occur in waters of greater than 5,000 feet, are driving a need for DP-2 vessels with very large capacities. The distance of these projects from shore, together with their water and well depths dictate the use of massive volumes of bulk drilling materials and related supplies. The OSVs that have been delivered as part of our fifth OSV newbuild program are among the largest in the world. With DWT capacities of 5,500 DWT to 6,200 DWT, we believe these ultra high-spec vessels provide our ultra-deepwater drilling customers vessel solutions that help them to maximize efficiencies and improve the logistical challenges prevalent in their projects.
Vessels that do not carry a DP-2 notation or have less than 2,500 DWT capacity typically operate in more shallow U.S. waters or in foreign locations in which DP-2 has not yet emerged as the dominant standard. Currently, 18 of our vessels are low-spec, comprising 13% of our fleet by DWT. The remaining 87% of our fleet is considered high-spec, including roughly 60% of our overall fleet that is ultra high-spec.

MPSVs
MPSVs also support the deepwater activities of the energy industry. MPSVs are distinguished from OSVs in that they are more specialized and often significantly larger vessels that are principally used for IRM activities, such as the subsea installation of well heads, risers, jumpers, umbilicals and other equipment placed on the seafloor. MPSVs are also utilized in connection with the setting of pipelines, the commissioning and de-commissioning of offshore facilities, the maintenance and/or repair of subsea equipment and the intervention of such wells, well testing and flow-back operations and other sophisticated deepwater operations. To perform these various functions, MPSVs are or can be equipped with a variety of lifting and deployment systems, including large capacity cranes, winches or reel systems, well intervention equipment, ROVs and accommodation facilities. The typical MPSV is outfitted with one or more deepwater cranes

4


employing active heave compensation technology, one or more ROVs and expansive accommodations for the offshore crew, including customer personnel. MPSVs can also be outfitted as a flotel to provide accommodations to large numbers of offshore construction and technical personnel involved in large-scale offshore projects, such as the commissioning of a floating offshore production facility. When in a flotel mode, the MPSV provides living quarters for personnel, catering, laundry, medical services, recreational facilities and offices. In addition, flotels coordinate and help to provide the facilities necessary for the offshore workers being accommodated to safely move from the vessel to other offshore structures being supported through the use of articulated gangways that allow personnel to "walk to work." Generally, MPSVs command higher day rates than OSVs due to their significantly larger relative size and versatility, as well as higher construction and operating costs.
370 class MPSVs
We have devised MPSVs that, in addition to the array of services described above, are also capable of being utilized to transport deck or bulk cargoes in capacities exceeding most other new generation OSVs. We own and operate two proprietary 370 class DP-2 new generation MPSVs with such capabilities. These MPSVs have approximately double the deadweight and three times the liquid mud barrel-capacity of one of our 265 class new generation OSVs and more than four times the liquid mud barrel-capacity of one of our 240 class new generation OSVs. Moreover, with their large tanks, these MPSVs have assisted in large volume deepwater well testing and flow-back operations, as well as supporting large drilling operations in remote or harsh conditions. Both of our 370 class MPSVs have certifications by the USCG that permit Jones Act-qualified operations as a supply vessel, industrial/construction vessel and as a petroleum and chemical tanker under subchapters “L”, “I”, “D”, and “O”, respectively. We believe that these vessels are not only the largest supply vessels in the world, but are also the only vessels in the world to have received all four of these certifications.
400 class and 310 class MPSVs
Until recently, due to a lack of Jones Act-qualified MPSVs, many customers would charter an OSV to carry equipment to location, which was then installed by a foreign flag MPSV. By eliminating the need for two vessels, we believe our customers will improve efficiencies and mitigate operational risks. Our Jones Act-qualified MPSVs are equipped with a heave-compensated knuckle-boom crane, helideck, accommodations for approximately 90-100 persons and are suitable for two or more work-class ROVs. Moreover, our Jones Act-qualified MPSVs are also equipped with below-deck cargo tanks, allowing them to expand their mission utility to include services more typically provided by OSVs.
In February 2016, we announced upgrades to the four remaining MPSVs under construction in our ongoing newbuild program. The modifications to the first two MPSVs, which were delivered in the third quarter of 2016, increased the berthing capacity, expanded the cargo-carrying capabilities and expanded the work area for ROVs. The modifications to the other two MPSVs will include the addition of a 60-foot mid-body plug, installation of an additional crane, increased berthing capacity, expanded cargo-carrying capacities and expanded work areas for ROVs. These two 400 class MPSVs are scheduled to be delivered in the first and third quarters of 2018. Because all four of these MPSVs are Jones Act-qualified, we expect that they will enable our customers to transport equipment from shore to the installation site to be installed by the MPSV without needing to use a second (domestic) vessel for transport like foreign-flagged MPSVs are required to do. We believe that, once delivered, the 400 class MPSVs will be the largest and most capable Jones Act-qualified MPSVs available in the market.

In April 2015, we also outfitted one of our 310 class OSVs that was placed in service under our ongoing newbuild program as a 310 class MPSV in flotel configuration. This U.S.-flagged, Jones Act-qualified MPSV includes a 35-ton knuckle-boom crane, a motion-compensated gangway and accommodations for 194 persons. Being Jones Act-qualified gives it mission flexibility that foreign flag flotels lack in the GoM.
430 class
We also operate the HOS Iron Horse and HOS Achiever, which are 430 class DP-3 new generation MPSVs. A DP-3 notation requires greater vessel and ship-system redundancies. DP-3 systems also include separate vessel compartments with fire-retardant walls for generators, prime movers, switchboards and most other DP components. These 430 class MPSVs are designed to handle a variety of global offshore energy applications, many of which are not dependent on the exploratory rig count. They are excellent platforms for those specialty services described above for our 400 and 310 class MPSVs with the exception of handling liquid cargoes. The HOS Iron Horse and the HOS Achiever are not U.S.-flagged vessels, however, they can engage in certain legally permissible operations in the U.S. that do not constitute coastwise trade. The HOS Achiever is currently configured as a flotel with accommodations for up to 270 personnel onboard, including the vessel's marine crew, hotel and catering staff. These accommodations allow this vessel to support the commissioning of deepwater installations around the world. Because flotel services do not typically involve the transportation of passengers, foreign-flag vessels, such as our 430 class MPSVs, can provide this service in the U.S.
We believe that our reputation for safety and technologically superior vessels, combined with our size and scale in certain core markets relative to our public company OSV peer group, enhance our ability to compete for work awarded by major oil companies, independent oil companies, national oil companies and the U.S. government, who are among our primary customers. These customers demand a high level of safety and technological advancements to meet the more stringent regulatory standards in the GoM. As our customers’ needs and requirements become more demanding, we expect that smaller vessel operators may struggle to meet these standards.

(1) 
“DP-1,” “DP-2” and “DP-3” mean various classifications, or equivalent, of dynamic positioning systems on new generation vessels to automatically maintain a vessel’s position and heading through anchor-less station keeping.
(2) 
These vessels are currently being constructed under our fifth OSV newbuild construction program with anticipated in-service dates during 2018.
(3) 
These six vessels were converted into 240 class DP-2 OSVs as part of our 200 class OSV retrofit program in 2013. They were originally constructed and placed in service in their prior Super 200 class DP-1 configuration in 1999 or 2000 and were acquired by us in August 2007.
We own long-term lease rights to two adjacent shore-base facilities located in Port Fourchon, Louisiana, named HOS Port. Port Fourchon’s proximity to the deepwater GoM provides a strategic logistical advantage for servicing drilling rigs, production facilities and other offshore installations and sites. We also utilize HOS Port as a shoreside facility for performing vessel maintenance, outfitting and other in-the-water shipyard activities. Developed as a multi-use facility, Port Fourchon has historically been a land base for offshore oil support services and the Louisiana Offshore Oil Port, or LOOP. According to industry sources, Port Fourchon services nearly all deepwater rigs and almost half of all shallow water rigs in the GoM. The HOS Port facility has approximately two years remaining on its current leases and three additional five-year renewal options on each parcel. The combined acreage of HOS Port is approximately 60 acres with total waterfront bulkhead of nearly 3,000 linear feet. HOS Port not only supports our existing fleet and customers’ deepwater logistics requirements, but it underscores our long-term commitment to and our long-term outlook for the deepwater GoM.
Principal Markets
OSVs and MPSVs operate worldwide, but are generally concentrated in relatively few offshore regions with high levels of exploration and development activity, such as the GoM, the North Sea, Southeast Asia, West Africa, Latin America, and the Middle East. Our core geographic markets are the GoM, Mexico and Brazil. In these markets we provide services to several major integrated oil companies as well as mid-size and large independent oil companies with deepwater and ultra-deepwater activities and to national oil companies such as PEMEX and Petrobras. We also occasionally operate in select international markets, which have included the rest of Latin America, West Africa, the Mediterranean Sea, the Black Sea and the Caribbean basin. We are often subcontracted by other oilfield service companies, both in the GoM and internationally, to provide a new generation fleet that enables them to render offshore oilfield services, such as well stimulation or other enhanced oil recovery activities, diving and ROV operations, construction, installation, inspection, maintenance, repair and decommissioning services. We also provide a specialized application of our new generation OSVs for use by the United States military.

While there is some vessel migration between regions, key factors such as mobilization costs, vessel suitability and government statutes prohibiting foreign-flagged vessels from operating in certain waters, or coastwise cabotage laws such as the Jones Act, can limit the migration of OSVs. Because some MPSVs are generally utilized for non-cargo operations, they are less limited by cabotage laws. Demand for OSVs, as evidenced by dayrates and utilization rates, is primarily related to offshore oil and natural gas exploration, development and production activity. Such activity is influenced by a number of factors, including the actual and forecasted price of oil and natural gas, the level of drilling permit activity, capital budgets of offshore exploration and production companies, and repair and maintenance needs in the deepwater oilfield.
Offshore exploration and production activities are increasingly focused on deep wells (as defined by total well depth rather than water depth), whether on the Outer Continental Shelf or in the deepwater or ultra-deepwater. These types of wells require high-specification equipment, which has driven the recent and nearly completed newbuild cycle for drilling rigs and for OSVs. There were 47 floating rigs under construction or on order on February 15, 2017 and, as of that date, there were options outstanding to build 10 additional floating rigs. In addition, on that date, there were 102 high-spec jack-up rigs under construction or on order worldwide, and there were options outstanding to build 14 additional high-spec jack-up rigs. Most, if not all, of these rigs were ordered prior to the downturn in oil prices that has persisted since late 2014. Consequently, the market for deepwater drilling rigs is expected to be over-supplied for the forseeable future. This oversupply of rigs may drive down the cost of contracting a drilling rig, with the result that more rigs are employed, which could positively impact utilization of supply vessels. Each drilling rig working on deep-well projects typically requires more than one OSV to service it, and the number of OSVs required is dependent on many factors, including the type of activity being undertaken, the location of the rig and the size and capacity of the OSVs. During normal operating conditions, based on the historical data for the number of floating rigs and OSVs working, we believe that two to four OSVs per rig are required in the GoM and even more OSVs are necessary per rig in Brazil where greater logistical challenges result in longer vessel turnaround times to service drill sites. Typically, during the initial drilling stage, more OSVs are required to supply drilling mud, drill pipe and other materials than at later stages of the drilling cycle. In addition, generally more OSVs are required the farther a drilling rig is located from shore. Under normal weather conditions, the transit time to deepwater drilling rigs in the GoM and Brazil can typically range from six to 24 hours for a new generation vessel. In Brazil, transit time for a new generation vessel to some of the newer, more logistically remote deepwater drilling rig locations are more appropriately measured in days, not hours. In addition to drilling rig support, deepwater and ultra-deepwater exploration and production activities should result in the expansion of other specialty-service offerings for our vessels. These markets include subsea construction support, installation, IRM work, and life-of-field services, which include well-stimulation, workovers and decommissioning.
Our charters are the product of either direct negotiation or a competitive proposal process, which evaluates vessel capability, availability and price. Our primary method of chartering in the GoM is through direct vessel negotiations with our customers on either a long-term or spot basis. In the international market, we sometimes charter through local entities in order to comply with cabotage or other local requirements. Some charters are solicited by customers through international vessel brokerage firms, which earn a commission that is customarily paid by the vessel owner. Our operations and management agreement with the U.S. Navy's Military Sealift Command was a sole source selection based upon certain capabilities unique to the Company that were developed while the applicable vessels were chartered to the Navy. All of our charters, whether long-term or spot, are priced on a dayrate basis, whereby for each day that the vessel is under contract to the customer, we earn a fixed amount of charter-hire for making the vessel available for the customer’s use. Many long-term contracts and all government, including national oil company, charters contain early termination options in favor of the customer; however, some have fees designed to discourage early termination. Long-term charters sometimes contain provisions that permit us to increase our dayrates in order to be compensated for certain increased operational expenses or regulatory changes.
Competition
The offshore support vessel industry is highly competitive. Competition primarily involves such factors as:
quality, capability and age of vessels;
quality, capability and nationality of the crew members;
ability to meet the customer’s schedule;
safety record, reputation, experience and;
price.

Our high-spec OSVs are predominately U.S.-flagged vessels, which qualify them under the Jones Act to engage in domestic coastwise trade. The Jones Act restricts the ability of vessels that are foreign-built, foreign-owned, foreign-crewed or foreign-flagged from engaging in coastwise trade in the United States. The transportation services typically provided by OSVs constitute coastwise trade as defined by the Jones Act. See "Item 1A-Risk Factors" for a more detailed discussion of the Jones Act. Consequently, competition for our services in the GoM is largely restricted to other U.S. vessel owners and operators, both publicly and privately held. We believe that we operate the second largest fleet by DWT of new generation Jones Act-qualified OSVs in the United States. Internationally, our OSVs compete against other U.S. owners, as well as foreign owners and operators of OSVs. Some of our international competitors may benefit from a lower cost basis in their vessels, which are usually not constructed in U.S. shipyards, as well as from lower crewing costs and favorable tax regimes. While foreign vessel owners cannot engage in U.S. coastwise trade, some cabotage laws in other parts of the world permit temporary waivers for foreign vessels if domestic vessels are unavailable. We and other U.S. and foreign vessel owners have been able to obtain such waivers in the foreign jurisdictions in which we operate.
Many of the services provided by MPSVs do not involve the transportation of merchandise and therefore are generally not considered coastwise trade under U.S. and foreign cabotage laws. Consequently, our MPSVs face, and the HOSMAX MPSVs being constructed under our fifth OSV newbuild program will face, competition from both foreign-flagged vessels and U.S.-flagged vessels for non-coastwise trade activities. However, because our MPSVs will be Jones Act-qualified, we believe our customers will achieve greater efficiency as our MPSVs will eliminate the need for customers to separately charter a Jones Act-qualified vessel to transport project cargo from a U.S. point to an installation site. In addition, our U.S.-flagged MPSVs will compete for projects with other international MPSVs as well as participate in the GoM and international OSV markets as large-capacity carriers of drilling fluids, petroleum products and deck cargos in support of deep-well exploration, development and production operations. Competition in the MPSV industry is significantly affected by the particular capabilities of a vessel to meet the requirements of a customer’s project. While operating in the GoM, our foreign-flagged DP-3 MPSVs are required to utilize U.S. crews while foreign-owned vessels have historically been allowed to employ non-U.S. mariners, often from low-wage nations. U.S. crews are often more expensive than foreign crews. Also, foreign MPSV owners may have more favorable tax regimes than ours. Consequently, prices for foreign-owned MPSVs in the GoM are often lower than prices we can charge. Finally, some potential MPSV customers are also owners of MPSVs that will compete with our vessels. However, we have, for some time, observed a clear preference by our customers for a “one-stop” Jones Act solution, which would provide improved efficiencies, derived from a single U.S.-flagged vessel as well as greater regulatory certainty as compliance questions continue to arise from the use of foreign-flagged vessels in the subsea GoM. In the post-Macondo GoM, we see this Jones Act preference as a long-term trend, not only for construction vessels but for vessels of all types working offshore.
We continue to observe intense scrutiny by our customers on the safety and environmental management systems of vessel operators. As a consequence, we believe that deepwater customers are increasingly biased towards companies that have demonstrated a financial and operational commitment and capacity to employ such systems. We believe this trend will, over time, make it difficult for small enterprises to compete effectively in the deepwater OSV and MPSV markets. Additionally, we have observed less willingness by operators to utilize DP-1 vessels in deepwater operations in the GoM. This trend will likely result in the retirement of non-DP vessels and a migration of DP-1 vessels to non-deepwater regions, such as the shelf, and certain international regions.
Although some of our principal competitors are larger or have more extensive international operations than we do, we believe that our financial strength, operating capabilities and reputation for quality and safety enable us to compete effectively with other fleets in the market areas in which we operate or intend to operate. In particular, we believe that the relatively young age and advanced features of our OSVs and MPSVs provide us with a competitive advantage. The ages of our high-spec new generation OSVs range from one year to 18 years with a weighted-average fleet age, based on DWT, of five years. In fact, approximately 80% of our active new generation OSVs have been placed in-service since January 1, 2008. The average age of the industry’s conventional U.S.-flagged OSV fleet is over 35 years and the industry's domestic new generation OSV fleet is approximately nine years. We believe that most of these older vessels are cold-stacked and many of them have been or will be permanently retired in the next few years due to physical and economic obsolescence. Worldwide competition for new generation vessels has been impacted in recent years by the increase in newbuild OSVs placed in-service to address greater customer interest in deep-well, deepwater and ultra-deepwater drilling activity and the decline in industry activity due to low oil prices. Upon completion of our fifth OSV newbuild program, we expect to own a fleet of 72 Upstream vessels of which 81% will be DP-2 or DP-3 with a weighted-average fleet age, based on DWT, of nine years in 2018.
Our success depends in large part on our ability to attract and retain highly skilled and qualified personnel. Our inability to hire, train and retain a sufficient number of qualified employees could impact our ability to manage, maintain

10


and grow our business. In crewing our vessels, we require skilled employees who can perform physically demanding work and operate complex vessel systems. As the result of our vessel stacking strategy, we have reduced our mariner headcount significantly. When these stacked vessels return to service, we will need to hire and train additional mariners to operate such vessels.
CUSTOMER DEPENDENCY
Our customers are generally limited to large, independent, integrated or nationally-owned energy companies. These firms are relatively few in number. The percentage of revenues attributable to a customer in any particular year depends on the level of oil and natural gas exploration, development and production activities undertaken by such customer, the availability and suitability of our vessels for the customer’s projects or products and other factors, many of which are beyond our control. For the year ended December 31, 2016, Royal Dutch Shell plc (including worldwide affiliates), Military Sealift Command and Hess Corporation each accounted for 10% or more of our consolidated revenues. For a discussion of significant customers in prior periods, see Note 13 to our consolidated financial statements.
GOVERNMENT REGULATION
Environmental Laws and Regulations
Our operations are subject to a variety of federal, state, local and international laws and regulations regarding the discharge of materials into the environment or otherwise relating to environmental protection. The requirements of these laws and regulations have become more complex and stringent in recent years and may, in certain circumstances, impose strict liability, rendering a company liable for environmental damages and remediation costs without regard to negligence or fault on the part of such party. Aside from possible liability for damages and costs including natural resource damages associated with releases of oil or hazardous materials into the environment, such laws and regulations may expose us to liability for the conditions caused by others or even acts of ours that were in compliance with all applicable laws and regulations at the time such acts were performed. Failure to comply with applicable laws and regulations may result in the imposition of administrative, civil and criminal penalties, revocation of permits, issuance of corrective action orders and suspension or termination of our operations. Moreover, it is possible that future changes in the environmental laws, regulations or enforcement policies that impose additional or more restrictive requirements or claims for damages to persons, property, natural resources or the environment could result in substantial costs and liabilities to us and could have a material adverse effect on our financial condition, results of operations or cash flows. We have performed what we consider to be appropriate environmental due diligence in connection with our operations and, where possible, we have taken all necessary steps to qualify for any applicable statutory defenses and limits of liability available under environmental regulations. We believe that we are in substantial compliance with currently applicable environmental laws and regulations.
OPA 90 and regulations promulgated pursuant thereto amend and augment the oil spill provisions of the Clean Water Act and impose a variety of duties and liabilities on “responsible parties” related to the prevention and/or reporting of oil spills and damages resulting from such spills in or threatening U.S. Waters, including the Outer Continental Shelf or adjoining shorelines. A “responsible party” includes the owner or operator of an onshore facility, pipeline or vessel or the lessee or permittee of the area in which an offshore facility is located. OPA 90 assigns liability to each responsible party for containment and oil removal costs, as well as a variety of public and private damages including the costs of responding to a release of oil, natural resource damages, damages for injury to, or economic losses resulting from, destruction of real or personal property of persons who own or lease such affected property. For any vessels, other than “tank vessels,” that are subject to OPA 90, the liability limits are the greater of $1,100 per gross ton or $939,800. A party cannot take advantage of liability limits if the spill was caused by gross negligence or willful misconduct or resulted from violation of a federal safety, construction or operating regulation. In addition, for vessels carrying crude oil from a well situated on the Outer Continental Shelf, the limits apply only to liability for damages (e.g. natural resources, real or personal property, subsistence use, reserves, profits and earnings capacity, and public services damages). The owner or operator of such vessel is liable for all removal costs resulting from a discharge without limits. If the party fails to report a spill or to cooperate fully in the cleanup, the liability limits likewise do not apply and certain defenses may not be available. Moreover, OPA 90 imposes on responsible parties the need for proof of financial responsibility to cover at least some costs in a potential spill. As required, we have provided satisfactory evidence of financial responsibility to the USCG for all of our vessels over 300 tons.

OPA 90 also imposes ongoing requirements on a responsible party, including preparedness and prevention of oil spills and preparation of an oil spill response plan. We have engaged the Marine Spill Response Corporation to serve as our Oil Spill Removal Organization for purposes of providing oil spill removal resources and services for our operations in

11


U.S. waters as required by the USCG. In addition, our Tank Vessel Response Plan and Non-Tank Vessel Response Plan have been approved by the USCG.
The Clean Water Act imposes strict controls on the discharge of pollutants into the navigable waters of the United States. The Clean Water Act also provides for civil, criminal and administrative penalties for any unauthorized discharge of oil or other hazardous substances in reportable quantities and imposes liability for the costs of removal and remediation of an unauthorized discharge, including the costs of restoring damaged natural resources. Many states have laws that are analogous to the Clean Water Act and also require remediation of accidental releases of petroleum in reportable quantities. Our OSVs routinely transport diesel fuel to offshore rigs and platforms and also carry diesel fuel for their own use. Our OSVs also transport bulk chemical materials used in drilling activities and liquid mud, which contain oil and oil by-products. We maintain vessel response plans as required by the Clean Water Act to address potential oil and fuel spills.
The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, also known as “CERCLA” or “Superfund,” and similar laws impose liability for releases of hazardous substances into the environment. CERCLA currently exempts crude oil from the definition of hazardous substances for purposes of the statute, but our operations may involve the use or handling of other materials that may be classified as hazardous substances. CERCLA assigns strict liability to each responsible party for response costs, as well as natural resource damages. Under CERCLA, responsible parties include not only owners and operators of vessels but also any person who arranged for the disposal or treatment, or arranged with a transporter for transport for disposal or treatment of hazardous substances, and any person who accepted hazardous substances for transport to disposal or treatment facilities. Thus, we could be held liable for releases of hazardous substances that resulted from operations by third parties not under our control or for releases associated with practices performed by us or others that were standard in the industry at the time.
The Resource Conservation and Recovery Act regulates the generation, transportation, storage, treatment and disposal of onshore hazardous and non-hazardous wastes and requires states to develop programs to ensure the safe treatment, storage and disposal of wastes. We generate non-hazardous wastes and small quantities of hazardous wastes in connection with routine operations. We believe that all of the wastes that we generate are handled in all material respects in compliance with the Resource Conservation and Recovery Act and analogous state statutes.
The USCG's final Ballast Rule became effective on June 21, 2012, and the EPA renewed the Vessel General Permit under the National Pollutant Discharge Elimination System on December 19, 2013. In addition, the International Maritime Organization, or IMO, ratified the International Convention for the Control and Management of Ships’ Ballast Water and Sediments on September 8, 2016, otherwise known as the Ballast Water Management Convention, or BWMC. The BWMC has similar standards to that of the USCG and EPA ballast water regulations and will enter into force on September 8, 2017. These regulations require all our existing vessels to meet certain standards pertaining to ballast water discharges. An exemption to certain compliance requirements in the U.S. is provided for vessels that operate within an isolated geographic region, as determined by the USCG. Most of our vessels operating in the GoM are exempt from the ballast water treatment requirements. However, for non-exempt vessels, ballast water treatment equipment may be required to be utilized on the vessel. In late 2016, the USCG approved certain types of ballast water treatment systems and, as a result, we will have to become compliant with ballast water treatment requirements that previously were waived in the U.S. Internationally, compliance with IMO’s BWMC is not expected to impact us until 2018, as implementation of these rules is based on the renewal of a vessel’s International Oil Pollution Prevention Certificate after September 8, 2017. We have currently estimated the cost of compliance with either the USCG's Ballast Rule or the BWMC to be approximately $250,000 per vessel that is required to be fitted with a treatment system. 
The Clean Air Act, or CAA, passed by Congress in 1970 regulates all air pollutants resulting from industrial activities. The 1990 amendments to the CAA established jurisdiction of offshore regions. Proposed and existing facilities and vessels must prepare, as part of their development plans and reporting procedures, detailed emissions data to prove compliance with the CAA and obtain necessary permits. We believe that all of our facilities and vessels have obtained the necessary permits and are operating in all material respects in compliance with the CAA. The EPA also imposed emissions regulations affecting vessels that operate in the United States. These regulations impose standards that may require modifications to our vessels at a cost that we have as yet been unable to estimate. Moreover, the EPA’s decision to regulate “greenhouse gases” as a pollutant may result in further regulations and compliance costs.

Climate Change
Greenhouse gas emissions have increasingly become the subject of international, national, regional, state and local attention. The EPA has adopted regulations under the Clean Air Act that require new and existing industrial facilities to obtain permits for carbon dioxide equivalent emissions above emission thresholds. In addition, the EPA adopted rules that mandate reporting of greenhouse gas data and other information by i) industrial sources, ii) suppliers of certain products, and iii) facilities that inject carbon dioxide underground. To the extent that these regulations may apply, we could be responsible for costs associated with complying with such regulations. Cap and trade initiatives to limit greenhouse gas emissions have been introduced in the European Union. Similarly, in prior years, numerous bills related to climate change have been introduced in the U.S. Congress, which could adversely impact most industries. In addition, future regulation of greenhouse gas could occur pursuant to future treaty obligations, statutory or regulatory changes or new climate change legislation in the jurisdictions in which we operate. It is uncertain whether any of these initiatives will be implemented. However, based on published media reports, we believe that it is unlikely that the current proposed initiatives in the U.S. will be implemented without substantial modification. If such initiatives are implemented, we do not believe that such initiatives would have a direct, material adverse effect on our operating results.
Restrictions on greenhouse gas emissions or other related legislative or regulatory enactments could have an effect in those industries that use significant amounts of petroleum products, which could potentially result in a reduction in demand for petroleum products and, consequently and indirectly, our offshore transportation and support services. We are currently unable to predict the manner or extent of any such effect. Furthermore, one of the asserted long-term physical effects of climate change may be an increase in the severity and frequency of adverse weather conditions, such as hurricanes, which may increase our insurance costs or risk retention, limit insurance availability or reduce the areas in which, or the number of days during which, our customers would contract for our vessels in general and in the GoM in particular. We are currently unable to predict the manner or extent of any such effect.
EMPLOYEES
On December 31, 2016, we had 797 employees, including 611 operating personnel and 186 corporate, administrative and management personnel. Excluded from these personnel totals are 78 third-country nationals that we contracted to serve on our vessels as of December 31, 2016. These non-U.S. mariners are typically provided by international crewing agencies. With the exception of 85 employees located in Brazil and Mexico, none of our employees are represented by a union or employed pursuant to a collective bargaining agreement or similar arrangement. We have not experienced any strikes or work stoppages, and our management believes that we continue to experience good relations with our employees.

Foreign Operations
Operating in foreign markets presents many political, social and economic challenges. Although we take measures to mitigate these risks, they cannot be completely eliminated. See "Item—1A Risk Factors" for a further discussion of the risks of operating in foreign markets.
SEASONALITY
Demand for our offshore support services is directly affected by the levels of offshore drilling and production activity. Budgets of many of our customers are based upon a calendar year, and demand for our services has historically been stronger in the second and third calendar quarters when allocated budgets are expended by our customers and weather conditions are more favorable for offshore activities. Many other factors, such as the expiration of drilling leases and the supply of and demand for oil and natural gas, may affect this general trend in any particular year. In addition, we typically have an increase in demand for our vessels to survey and repair offshore infrastructure immediately following major hurricanes or other named storms in the GoM.

ITEM 1A—Risk Factors
Our results of operations and financial condition can be adversely affected by numerous risks. You should carefully consider the risks described below as well as the other information we have provided in this Annual Report on Form 10-K. The risks described below are not the only ones we face. You should also consider the factors contained in our “Forward Looking Statements” disclaimer found on page ii of this Annual Report on Form 10-K. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations.
We may not have the funds available or be able to obtain the funds necessary to meet the obligations relating to our 2019 convertible senior notes, our 2020 senior notes, or our 2021 senior notes.
Our 2019 convertible senior notes, our 2020 senior notes, and our 2021 senior notes, which collectively have a face value of $1,125 million, mature in September 2019, April 2020, and March 2021, respectively. In addition, upon the occurrence of certain change of control events, as defined in the indentures governing the 2020 senior notes and the 2021 senior notes, holders of such notes would have the right to require us to repurchase such notes at 101% of their principal amount, plus accrued and unpaid interest. Further, upon certain fundamental changes as defined in the indenture governing the 2019 convertible senior notes, holders of such notes would have the right to require us to repurchase such notes at 100% of their principal amount, plus any accrued and unpaid interest. We do not expect to have sufficient cash on hand and cash flow from operations to meet all of these obligations as they come due and will need to access additional sources of capital in order to refinance some or all of this indebtedness prior to maturity. There can be no assurance that we will succeed in accessing new capital or, if successful, that the capital we raise will not be expensive or dilutive to stockholders. Failure to meet our obligations related to any tranche of our senior notes may result in the acceleration of our other indebtedness and result in a material adverse effect on our financial condition and results of operations.
As a result of the ongoing declines in oil prices that began in late 2014, our clients have reduced and may further reduce spending on exploration and production projects, resulting in a decrease in demand for our services.
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 or periods of surplus oil and natural gas generally result in lower prices for these commodities and often impact 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 vessel dayrates and utilization for our vessels historically decline as well. This has been the case, beginning in October 2014 and continuing into 2017.
Oil prices worldwide have dropped significantly since 2014. If the current depressed oil and natural gas prices persist for a prolonged period, or decline further, oil and gas exploration and production companies will likely cancel or curtail additional drilling programs and lower production spending on existing wells even more than they have already, thereby further reducing demand for our services.
Any prolonged reduction in the overall level of exploration and development activities, whether resulting from changes in oil and gas prices or otherwise, could materially and adversely affect us by negatively impacting:
our revenues, cash flows and profitability;
the fair market value of our vessels;
our ability to maintain or increase our borrowing capacity;
our ability to obtain capital to re-finance our existing debt or expand our business through acquisitions, or otherwise;
the collectability of our receivables; and
our ability to retain or rehire skilled personnel whom we would need in the event of an upturn in the demand for our services.
If any of the foregoing were to occur, it could have a material adverse effect on our business and financial results.

15


Increases in the supply of vessels could decrease dayrates.
In addition to our fifth OSV newbuild program, which is nearing completion, certain of our competitors previously announced plans to construct new vessels to be deployed in domestic and foreign locations, thus adding to the available vessel capacity. A remobilization to the GoM oilfield of U.S.-flagged vessels currently operating in other regions or in non-oilfield applications would result in an increase in vessel capacity in the GoM, one of our core markets. Similarly, vessel capacity in foreign markets, including our core markets of Mexico and Brazil, may also be impacted by U.S.-flagged or other vessels migrating to such foreign locations. Further, a repeal, suspension or significant modification of the Jones Act, or the administrative erosion of its benefits, permitting vessels that are either foreign-flagged, foreign-built, foreign-owned, foreign-controlled or foreign-operated to engage in the U.S. coastwise trade, would also result in an increase in capacity. Any increase in the supply of OSVs or MPSVs, whether through new construction, refurbishment or conversion of vessels from other uses, remobilization or changes in law or its application, could not only increase competition for charters and lower utilization and dayrates, which would adversely affect our revenues and profitability, but could also worsen the impact of the current or any future downturn in the oil and gas industry on our results of operations and financial condition. Because some services provided by MPSVs are not protected by the Jones Act, foreign competitors may bring additional MPSVs to the GoM or build additional MPSVs that we will compete with domestically or internationally for such services.
The level of offshore oil and gas exploration, development and production activity has historically been volatile and is likely to continue to be so in the future. The level of activity is subject to large fluctuations in response to relatively minor changes in a variety of factors that are beyond our control
Changes in, among others, the following factors can negatively impact our performance:
worldwide demand for oil and natural gas;
prevailing oil and natural gas prices and expectations about future prices and price volatility;
changes in capital spending budgets by our customers;
the ability of oil and gas companies to generate or otherwise obtain funds for exploration and production;
local and international political and economic conditions and policies;
unavailability of drilling rigs in our core markets of the GoM, Mexico and Brazil;
the cost of offshore exploration for, and production and transportation of, oil and natural gas;
successful exploration for, and production and transportation of, oil and natural gas from onshore sources;
consolidation of oil and gas and oil service companies operating offshore;
availability and rate of discovery of new oil and natural gas reserves in offshore areas;
technological advances affecting energy production and consumption;
the ability or willingness of the Organization of Petroleum Exporting Countries, or OPEC, to set and maintain production levels for oil;
oil and natural gas production levels by non-OPEC countries;
weather conditions; and
environmental and other regulations affecting our customers and their other service providers.
Since late 2014, we have observed a significant decline in oil prices, which has caused oil companies to announce and implement significant reductions in their capital spending programs, that is the source of much of our business activity. A prolonged reduction in oil prices is having and could continue to have a significant adverse and long-term impact on the Company’s financial condition and results of operations.

16


The early termination of contracts on our vessels could have an adverse effect on our operations.
Some of the long-term contracts for our vessels and all contracts with governmental entities and national oil companies contain early termination options in favor of the customer; however, some have early termination remedies or other provisions designed to discourage the customers from exercising such options. We cannot assure that our customers would not choose to exercise their termination rights in spite of such remedies or the threat of litigation with us. Until replacement of such business with other customers, any termination could temporarily disrupt our business or otherwise adversely affect our financial condition and results of operations. We might not be able to replace such business on economically equivalent terms. In addition, during the current and prior downturns, we have experienced customers requesting contractual concessions even though contrary to existing contractual terms. While not legally required to give concessions, commercial considerations may dictate that we do so, given the relatively few deepwater customers operating in the GoM.
Intense competition in our industry could reduce our profitability and market share.
Contracts for our vessels are generally awarded on an intensely competitive basis. Some of our competitors are willing to accept lower dayrates in order to maintain utilization, which can have a negative impact on our dayrates and utilization. As a result, we could lose customers and market share to these competitors. Similarly, competition in various markets may also be impacted by U.S.-flagged vessels migrating in and out of foreign locations due to the pace of drilling activity in the GoM.
Additional reductions in Petrobras' announced plans for exploration and production activities offshore
Brazil could have a material adverse effect on the market for high-spec OSVs.

Petrobras accounts for a substantial portion of global deepwater drilling activity and has publicly announced plans to reduce its investment in exploration and production activities by roughly $24 billion from 2017 through 2021 compared to the prior four-year 2015-2019 plan. This reduction and any decision by Petrobras to further reduce the scope or pace of its announced exploration and production plans offshore Brazil could negatively impact the worldwide market for high-spec OSVs and limit our ability to effect further expansion into this market.
We may not be able to complete the construction of our remaining newbuild program or may experience delays or cost overruns related to that program.
We are currently constructing the last two MPSVs under our pending newbuild program. These vessels are large and complex. We are required to make remaining milestone payments to the shipyard and other vendors totaling approximately $71 million, the majority of which payments will be due in 2018 upon delivery of each vessel from the shipyard. While we have sufficient cash on hand today to meet these obligations, unforeseen events could result in our inability to fund these obligations when they come due, which could have an adverse impact on our business plans, financial condition and results from operations. Additionally, the shipyard might be delayed or unforeseen events could result in significant cost overruns for which, under certain circumstances, we might be responsible. Such delays or cost overruns could impact our ability to meet our obligations to the shipyard and could otherwise materially and adversely affect our financial condition and results from operations.
The failure to successfully complete repairs, maintenance and routine drydockings on-schedule and on-budget could adversely affect our financial condition and results of operations.
We routinely engage shipyards to drydock our vessels for regulatory compliance and to provide repair and maintenance. These activities are subject to the risks of delay and cost overruns inherent in any large construction project, including shortages of equipment, lack of shipyard availability, unforeseen engineering problems, work stoppages, weather interference, unanticipated cost increases, including costs of steel, inability to obtain necessary certifications and approvals and shortages of materials or skilled labor. Significant delays could result in adverse effects to our anticipated contract commitments or revenues. Significant cost overruns could adversely affect our financial condition and results of operations.

17


We have grown, and may continue to grow, through acquisitions that give rise to risks and challenges that could adversely affect our future financial results.
We regularly consider possible acquisitions of single vessels, vessel fleets and businesses that complement our existing operations to enable us to grow our business. Acquisitions can involve a number of special risks and challenges, including:
diversion of management time and attention from our existing business and other business opportunities;
delays in closing or the inability to close an acquisition for any reason, including third party consents or approvals;
any unanticipated negative impact on us of disclosed or undisclosed matters relating to any vessels or operations acquired;
loss or termination of employees, including costs associated with the termination or replacement of those employees;
assumption of debt or other liabilities of the acquired business, including litigation related to the acquired business;
the incurrence of additional acquisition-related debt as well as increased expenses and working capital requirements;
dilution of stock ownership of existing stockholders;
increased costs and efforts in connection with compliance with Section 404 of the Sarbanes-Oxley Act; and
substantial accounting charges for restructuring and related expenses, impairment of goodwill, amortization of intangible assets, and stock-based compensation expense.
Even if we consummate an acquisition, the process of integrating acquired operations into our own may result in unforeseen operating difficulties and costs and may require significant management attention and financial resources. In addition, integrating acquired businesses may impact the effectiveness of our internal controls over financial reporting. In the currently depressed market for OSVs, we might not be able to place vessels we acquire into immediate service, which will result in our paying for the cost to stack these vessels and eventually the cost to bring them out of stack, which could be a significant barrier to their utilization if we do not have sufficient liquidity to justify such expenses. Any of the foregoing, and other factors, could harm our ability to achieve anticipated levels of utilization and profitability from acquired vessels or businesses or to realize other anticipated benefits of acquisitions.
We can give no assurance that we will be able to identify desirable acquisition candidates or that we will be successful in entering into definitive agreements or closing such acquisitions on satisfactory terms. An inability to acquire additional vessels or businesses may limit our growth potential.
Our contracts with the United States Government could be impacted by budget cuts.
Our government contracts depend upon annual funding commitments authorized by Congress. In a period of government budget cuts or other political events, our contracts might not be re-authorized, resulting in a material decline in our anticipated revenues.
We are subject to complex laws and regulations, including environmental regulations that can adversely affect the cost, manner or feasibility of doing business.
Increasingly stringent federal, state, local and foreign laws and regulations governing worker health and safety and the manning, construction and operation of vessels significantly affect our operations. Many aspects of the marine industry are subject to extensive governmental regulation by the USCG, the National Transportation Safety Board, the EPA and the United States Customs Service, and their foreign equivalents, and to regulation by private industry organizations such as the American Bureau of Shipping. The USCG and the National Transportation Safety Board set safety standards and are authorized to investigate vessel accidents and recommend improved safety standards, while the USCG and Customs Service are authorized to inspect vessels at will. Our operations are also subject to international conventions, federal, state, local and international laws and regulations that control the discharge of pollutants into the

18


environment or otherwise relate to environmental protection. Compliance with such laws, regulations and standards may require installation of costly equipment, increased manning, specific training, and/or operational changes. While we endeavor to comply with all applicable laws, circumstances might exist where we might not come into complete compliance with applicable laws and regulations which could result in administrative and civil penalties, criminal sanctions, imposition of remedial obligations or the suspension or termination of our operations. Some environmental laws impose strict liability for remediation of spills and releases of oil and hazardous substances, which could subject us to liability without regard to whether we were negligent or at fault. These laws and regulations may expose us to liability for the conduct of, or conditions caused by, others, including charterers. Moreover, these laws and regulations could change in ways that substantially increase costs that we may not be able to pass along to our customers. Any changes in applicable conventions or laws, regulations or standards that would impose additional requirements or restrictions on our or our oil and gas exploration and production customers’ operations could adversely affect our financial condition and results of operations. It is possible that laws and regulations may become even more stringent, which could also adversely affect our financial condition and results of operations.
We are also subject to the Merchant Marine Act of 1936, which provides that, upon proclamation by the President of a national emergency or a threat to the security of the national defense, the Secretary of Transportation may requisition or purchase any vessel or other watercraft owned by United States citizens (which includes United States corporations), including vessels under construction in the United States. If one of our OSVs or MPSVs were purchased or requisitioned by the federal government under this law, we would be entitled to be paid the fair market value of the vessel in the case of a purchase or, in the case of a requisition, the fair market value of charter hire. We would also not be entitled to be compensated for any consequential damages we suffer as a result of the requisition or purchase of any of our OSVs or MPSVs. The purchase or the requisition for an extended period of time of one or more of our vessels could adversely affect our results of operations and financial condition.
Finally, we are subject to the Merchant Marine Act of 1920, commonly referred to as the Jones Act, which requires that vessels engaged in coastwise trade to carry cargo between U.S. ports be documented under the laws of the United States and be controlled by U.S. citizens. A corporation is not considered a U.S. citizen unless, among other things, at least 75% of the ownership of voting interests with respect to its equity securities are held by U.S. citizens. We endeavor to ensure that we would be determined to be a U.S. citizen as defined under these laws by including in our certificate of incorporation certain restrictions on the ownership of our capital stock by non-U.S. citizens and establishing certain mechanisms to maintain compliance with these laws. If we are determined at any time not to be in compliance with these citizenship requirements, our vessels might become ineligible to engage in the coastwise trade in U.S. domestic waters, and our business and operating results would be adversely affected.
The Jones Act’s provisions restricting coastwise trade to vessels controlled by U.S. citizens have been circumvented in recent years by foreign interests that seek to engage in trade reserved for vessels controlled by U.S. citizens and otherwise qualifying for coastwise trade. Legal challenges against such actions are difficult, costly to pursue and are of uncertain outcome. In addition, the Jones Act is often criticized and there are efforts underway by affected interest groups to seek its repeal. To the extent such efforts are successful and foreign competition is permitted, such competition could have a material adverse effect on domestic companies in the offshore service vessel industry and on our financial condition and results of operations. In addition, in the interest of national defense, the Secretary of Homeland Security is authorized to suspend the coastwise trading restrictions imposed by the Jones Act on vessels not controlled by U.S. citizens. Such waivers are granted from time-to-time.
Our business involves many operating risks that may disrupt our business or otherwise result in substantial losses, and insurance may be unavailable or inadequate to protect us against these risks.
Our vessels are subject to operating risks such as:
catastrophic marine disaster;
adverse weather and sea conditions;
mechanical failure;
collisions or allisions;
oil and hazardous substance spills;

19


navigation errors;
acts of God; and
war and terrorism.
The occurrence of any of these events may result in damage to or loss of our vessels or other property, injury or death of people or contamination of the environment. If any of these events were to occur, we could be exposed to liability for resulting damages and possible penalties that, pursuant to typical marine indemnity policies, we must pay and then seek reimbursement from our insurer. Affected vessels may also be removed from service and thus be unavailable for income-generating activity. While we believe our insurance coverage is adequate and insures us against risks that are customary in the industry, we may be unable to renew such coverage in the future at commercially reasonable rates. Moreover, existing or future coverage may not be sufficient to cover claims that may arise and we do not maintain insurance for loss of income resulting from a marine casualty.
Our operations in international markets and shipyard activities in foreign shipyards subjects us to risks inherent in conducting business internationally.
We derive a portion of our revenues from foreign sources. In addition, certain of our shipyard repair and procurement activities are being conducted with foreign vendors. We therefore face risks inherent in conducting business internationally, such as legal and governmental regulatory requirements, potential vessel seizure or nationalization of assets, import-export quotas or other trade barriers, difficulties in collecting accounts receivable and longer collection periods, political and economic instability, kidnapping of or assault on personnel, piracy, adverse tax consequences, difficulties and costs of staffing international operations and language and cultural differences. We do not hedge against foreign currency risk. While we endeavor to contract in U.S. Dollars when operating internationally, some contracts may be denominated in a foreign currency, which would result in a foreign currency exposure risk. All of these risks are beyond our control and difficult to insure against. We cannot predict the nature and the likelihood of any such events. If such an event should occur, however, it could have a material adverse effect on our financial condition and results of operations.
We may lose the right to operate in some international markets in which we have a presence.
In certain foreign markets in which we operate, most notably Mexico, we sometimes depend upon governmental waivers of cabotage laws. These waivers could be revoked or made more burdensome, which could result in our inability to continue our operations or materially increase the costs of operating in such foreign locations. In addition, our foreign customers are often large state-owned oil companies that have monopolies or near monopolies in their home countries. These companies sometimes impose contractual requirements or restrictions that cannot be negotiated away and that can impose significant operating risks upon us. From time to time, we have challenged these contractual actions in foreign markets, which entails significant risks.
Future results of operations depend on the long-term financial stability of our customers.
Some of the contracts we enter into for our vessels are full utilization contracts with initial terms ranging from one to five years. We enter into these long-term contracts with our customers based on a credit assessment at the time of execution. Our financial condition in any period may therefore depend on the long-term stability and creditworthiness of our customers. We can provide no assurance that our customers will fulfill their obligations under our long-term contracts and the insolvency or other failure of a customer to fulfill its obligations under such contracts could adversely affect our financial condition and results of operations.
We may be unable to attract and retain qualified, skilled employees necessary to operate our business.
Our success depends in large part on our ability to attract and retain highly skilled and qualified personnel. Our inability to hire, train and retain a sufficient number of qualified employees could impair our ability to manage, maintain and grow our business.
In crewing our vessels, we require skilled employees who can perform physically demanding work. As a result of the recent volatility of the oil and gas industry, we have significantly reduced our mariner headcount. Additionally, as a result of such volatility, vessel employees and potential employees may choose to pursue employment in fields that offer a more desirable work environment at wage rates that are competitive with ours. Further, unlike the current weak market

20


conditions, during normal market conditions, we face strong competition within the broader oilfield industry for employees and potential employees, including competition from drilling rig operators for our fleet personnel. We may have difficulty hiring employees or finding suitable replacements as needed and, once normal market conditions return, should a reduced pool of workers arise, it is possible that we would have to raise wage rates or increase our benefits offered to attract workers and to retain our current employees. In such circumstances, should we not be able to increase our service rates to our customers to compensate for wage-rate increases or recruit qualified personnel to operate our vessels at full utilization, our financial condition and results of operations may be adversely affected.
Our employees are covered by federal laws that may subject us to job-related claims in addition to those provided by state laws.
Some of our employees are covered by provisions of the Jones Act, the Death on the High Seas Act and general maritime law. These laws preempt state workers’ compensation laws and permit these employees and their representatives to pursue actions against employers for job-related incidents in federal courts based on tort theories. Because we are not generally protected by the damage limits imposed by state workers’ compensation statutes for these types of claims, we may have greater exposure for any claims made by these employees.
Our success depends on key members of our management, the loss of whom could disrupt our business operations.
We depend to a large extent on the efforts and continued employment of our executive officers and key management personnel. We do not maintain key-man insurance. The loss of services of one or more of our executive officers or key management personnel could have a negative impact on our financial condition and results of operations.
Restrictions contained in the indentures governing our 2020 senior notes, our 2021 senior notes, and in the agreement governing our revolving credit facility may limit our ability to obtain additional financing and to pursue other business opportunities.
Covenants contained in the indenture governing our 2020 senior notes, in the indenture governing our 2021 senior notes and in the agreement governing our revolving credit facility require us to meet certain financial tests, which may limit or otherwise restrict:
our flexibility in operating, planning for, and reacting to changes, in our business;
our ability to dispose of assets, withstand current or future economic or industry downturns and compete with others in our industry for strategic opportunities; and
our ability to obtain additional financing for working capital, refinancing of existing debt, capital expenditures, including our newbuild programs, acquisitions, general corporate and other purposes.
We have high levels of fixed costs that will be incurred regardless of our level of business activity.
Our business has high fixed costs. Downtime or low productivity due to reduced demand, as is currently being experienced, from weather interruptions or other causes can have a significant negative effect on our operating results and financial condition. In addition, given our recent vessel stackings, our fixed costs are borne by a substantially smaller active fleet of vessels.
Our revenues and operating results may vary significantly from quarter to quarter due to a number of factors such as volatility in our vessel dayrates, changes in utilization, vessel incidents and other unforeseen matters. Many of these factors that may cause our actual financial results to vary from our publicly disclosed earnings guidance and forecasts are outside of our control.
Our actual financial results might vary from those anticipated by us or by securities analysts and investors, and these variations could be material. From time to time we publicly provide various forms of guidance, which reflect our projections about future market expectations and operating performance. The numerous assumptions underlying such guidance may be impacted by factors that are beyond our control and might not turn out to be accurate. Although we believe that the assumptions underlying our projections are reasonable when such projections are made, actual results could be materially different, particularly with respect to our MPSVs.

21


We are susceptible to unexpected increases in operating expenses such as crew wages, materials and supplies, maintenance and repairs, and insurance costs.
Many of our operating costs, such as crew wages, materials and supplies, maintenance and repairs, and insurance costs, are unpredictable and vary based on events beyond our control. Our gross margins will vary based on fluctuations in our operating costs. If our costs increase or we encounter unforeseen costs, we may not be able to recover such costs from our customers, which could adversely affect our financial position, results of operations and cash flows.
Stacked vessels may introduce additional operational issues.
In recognition of weak market conditions, we have elected to stack OSVs and MPSVs on various dates since October 1, 2014. We may choose to stack additional vessels should market conditions warrant. In connection with such stackings, we have reduced our mariner headcount significantly. Operationally, we limit the number of persons available to maintain such stacked vessels. Also, we have fewer revenue-producing units in service that can contribute to our results and contribute cash flows to cover our fixed costs and commitments. When stacked vessels return to service, we will incur previously deferred drydocking costs for regulatory recertifications and may incur costs to hire and train mariners to operate such vessels. Delay in reactivating stacked vessels and the costs and other expenses related to the reactivation of stacked vessels could have a material adverse effect on our cash flows and results of operations.
We may be adversely affected by uncertainty in the global financial markets.
Our future results may be impacted by volatility, weakness or deterioration in the debt and equity capital markets. Inflation, deflation, or other adverse economic conditions may negatively affect us or parties with whom we do business resulting in their non-payment or inability to perform obligations owed to us, such as the failure of customers to honor their commitments, the failure of shipyards and major suppliers to complete orders or the failure by banks to provide expected funding under our revolving credit agreement. Additionally, credit market conditions may slow our collection efforts as customers experience increased difficulty in obtaining requisite financing, potentially leading to lost revenue and higher than normal accounts receivable. This could result in greater expense associated with collection efforts and increased bad debt expense.
Any significant softening in the already limited global economic recovery may adversely impact our ability to issue additional debt and equity in the future on acceptable terms. We cannot be certain that additional funding will be available if needed and to the extent required, on acceptable terms.
We may be unable to collect amounts owed to us by our customers.
We typically grant our customers credit on a short-term basis. Related credit risks are inherent as we do not typically collateralize receivables due from customers. We provide estimates for uncollectible accounts based primarily on our judgment using historical losses, current economic conditions and individual evaluations of each customer as evidence supporting the receivables valuations stated on our financial statements. However, our receivables valuation estimates may not be accurate and receivables due from customers reflected in our financial statements may not be collectible.
Future changes in legislation, policy, restrictions or regulations for drilling in the United States that cause delays or deter new drilling could have a material adverse effect on our financial position, results of operations and cash flows.
In response to the April 20, 2010, Deepwater Horizon incident, the regulatory agencies with jurisdiction over oil and gas exploration, including the DOI, imposed temporary moratoria on drilling operations, by requiring operators to reapply for exploration plans and drilling permits that had previously been approved, and by adopting numerous new regulations and new interpretations of existing regulations regarding offshore operations that are applicable to our customers and with which their new applications for exploration plans and drilling permits must prove compliant. Compliance with these new regulations and new interpretations of existing regulations have materially increased the cost of drilling operations in the GoM. These additional compliance costs could materially adversely impact our business, financial position or results of operations.

The fundamental change purchase feature of our 2019 convertible senior notes and the change of control purchase features of our 2020 senior notes and our 2021 senior notes and provisions of our certificate of incorporation, bylaws, stockholder rights plan and Delaware law may delay or prevent an otherwise beneficial takeover attempt of the Company.
The terms of our 2019 convertible senior notes require us to purchase the notes for cash in the event of a fundamental change, as defined in the applicable indenture. Upon a change in control, our 2020 senior notes and our 2021 senior notes require us to repurchase such senior notes at 101% of aggregate principal. A takeover of the Company would trigger the requirement that we purchase the 2019 convertible senior notes, the 2020 senior notes and the 2021 senior notes. Furthermore, our certificate of incorporation and bylaws, Delaware corporations law, and our stockholder rights plan contain provisions that could have the effect of making it more difficult for a third party to acquire, or discourage a third party from attempting to acquire, control of us. These provisions could limit the price that investors might be willing to pay in the future for shares of our common stock and may have the effect of delaying or preventing a takeover of the Company that would otherwise be beneficial to investors.
Our stock price has been volatile, declining precipitously from time to time during the period from 2013 through the present, and it could decline again.
The securities markets in general and our common stock in particular have experienced significant price and volume volatility in recent years. The market price and trading volume of our common stock may continue to experience significant fluctuations due not only to general stock market conditions but also to a change in sentiment in the market regarding our operations or business prospects or those of companies in our industry. In addition to the other risk factors discussed above, the price and volume volatility of our common stock may be affected by:
factors influencing the levels of global oil and natural gas exploration and exploitation activities, such as the current depressed prices for oil or natural gas;
the ability or willingness of OPEC to set and maintain production levels for oil;
oil and gas production levels by non-OPEC countries;
operating results that vary from the expectations of securities analysts and investors;
disasters such as the Deepwater Horizon incident in the Gulf of Mexico in 2010;
the operating and securities price performance of companies that investors or analysts consider comparable to us;
actions by rating agencies related to our 2019 convertible senior notes, our 2020 senior notes, or our 2021 senior notes;
geopolitical risks;
announcements of strategic developments, acquisitions and other material events by us or by our competitors; and
changes in global financial markets and global economies and general market conditions, such as interest rates, commodity and equity prices and the value of financial assets.

Item 3—Legal Proceedings

In December 2000, LEEVAC Marine Inc. (a predecessor entity to our current subsidiary Hornbeck Offshore Transportation, LLC, or HOT) was one of several companies that formed a limited liability company, SSIC Remediation, LLC, or SSIC, which conducted interim phase environmental remedial activities at the SBA Shipyards site in Jennings, Louisiana pursuant to a December 9, 2002 Order and Agreement with the EPA. In 2015, the EPA notified SSIC’s counsel of its renewed interest in the site and on September 9, 2016 published a final rule (effective October 11, 2016) adding the site to the General Superfund section of the CERCLA National Priorities List. In November 2016, HOT and nine other parties voluntarily entered into an Administrative Settlement Agreement and Order on Consent to conduct a Remedial Investigation/Feasibility Study, or RIFS, in connection with the site. HOT has accrued a liability of $0.1 million to cover expenses anticipated to be incurred with respect to conducting the RIFS. HOT’s anticipated percentage of liability for the RIFS cost and subsequent cleanup efforts with other members of the group is 4%. The Company has not made a judgment concerning the ultimate cost of clean up should it be required.

On January 31, 2017, we had 23 holders of record of our common stock.
We have not previously declared or paid, and we do not plan to declare or pay in the foreseeable future, any cash dividends on our common stock. Our current intention is to retain all additional cash that our business generates to cover all of our growth capital expenditures, commercial-related capital expenditures, annually recurring cash debt service, maintenance capital expenditures and cash income taxes. Any future payment of cash dividends or stock or debt repurchases will depend upon our financial condition, capital requirements, plans to reduce our long-term debt and our earnings, as well as other factors that our Board of Directors may deem relevant. In addition, the indentures governing our 2020 senior notes, our 2021 senior notes and the agreement governing our revolving credit facility include restrictions on our ability to pay cash dividends on our common stock. See "Item 7-Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 6 to our consolidated financial statements for further discussion.
See "Item 12-Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters” for information regarding shares of common stock authorized for issuance under our equity compensation plans.
Repurchase of Common Stock
On October 28, 2014, our Board of Directors authorized us to repurchase up to $150 million in shares of our common stock using different methods including, but not limited to, open-market purchases, privately negotiated transactions, accelerated share repurchases and Rule 10b5-1 trading plans. The timing and amount of the repurchases depends on several factors, such as market conditions, applicable legal requirements, available liquidity, the discretion of management and other appropriate factors. The repurchase program does not obligate us to acquire any particular amount of common stock and may be modified, suspended or discontinued at any time. As of December 31, 2016, we had repurchased and retired 891,396 shares at an average price of $28.05 per share. The repurchased shares cost a total of $25 million and represented roughly 2.5% of our total shares outstanding prior to the commencement of the program. As of February 24, 2017, no additional shares had been repurchased.

(1) 
Represents other operating income and expenses, including equity in income from investments and foreign currency transaction gains or losses.
(2) 
For the year ended December 31, 2016, due to a net loss, the Company excluded from the calculation of loss per share the effect of equity awards representing rights to acquire 975 shares of common stock. For the year ended December 31, 2015, the Company had 322 anti-dilutive stock options. For the years ended December 31, 2014, 2013 and 2012, the Company had no anti-dilutive stock options. See Note 3 of our consolidated financial statements for more information about diluted shares outstanding.
(3) 
Includes working capital (deficit) from discontinued operations in the amount of $470, $1,461, and $(1,750) as of December 31, 2014, 2013, and 2012, respectively.
(4) 
Includes total assets from discontinued operations in the amount of $470, $2,337, and $176,277 as of December 31, 2014, 2013 and 2012, respectively.
(5) 
Excludes imputed original issue discount associated with our 2026 convertible senior notes in the amount of $11,093 as of December 31, 2012. Also excludes deferred financing costs associated with our 2026 convertible senior notes in the amount of $836 as of December 31, 2012. These notes were putable by the holders to the Company on November 15, 2013 and therefore were classified as short-term debt. These notes were converted or redeemed in full by the Company in November 2013.
(6) 
Excludes original issue discount associated with our 2017 senior notes in the amount of $4,771 as of December 31, 2012; and imputed original issue discount associated with our 2019 convertible senior notes in the amount of $31,093, $41,600, $51,528, $60,908 and $69,699 as of December 31, 2016, 2015, 2014, 2013 and 2012, respectively.

(8) 
See our discussion of EBITDA as a non-GAAP financial measure immediately following these footnotes.
(9) 
Excluded from the Other Operating Data are the results of operations for our MPSVs, our shore-base facility, and vessel management services. Due to the fact that each of our MPSVs have a workload capacity and significantly higher income generating potential than each of our new generation OSVs, the utilization and dayrate levels of our MPSVs could have a very large impact on our results of operations. For this reason, our consolidated operating results, on a period-to-period basis, are disproportionately impacted by the level of dayrates and utilization achieved by our MPSVs.
(10) 
We owned 62 new generation OSVs as of December 31, 2016. Our average number of new generation OSVs for the years ended December 31, 2016, 2015, 2014, 2013, and 2012, reflect the deliveries of certain vessels under our fourth and fifth OSV newbuild programs. Please refer to Our Vessels on page 7 of this Form 10-K for more information about vessel names and placed in-service dates. Excluded from this data is one conventional OSV, which was sold during 2016 that was considered a non-core asset.
(11) 
In response to weak market conditions, we elected to stack certain of our new generation OSVs on various dates in 2009 and 2010. Based on improved market conditions, we had re-activated all of our stacked new generation OSVs by June 30, 2013. During 2014, we experienced weak market conditions for which we elected to stack certain of our new generation OSVs on various dates during the fourth quarter of 2014 and throughout 2015 and 2016.
(12) 
Utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues.
(13) 
Effective utilization rate is based on a denominator comprised only of vessel-days available for service by the active fleet, which excludes the impact of stacked vessel days.
(14) 
Average dayrates represent average revenue per day, which includes charter hire, crewing services and net brokerage revenues, based on the number of days during the period that the OSVs generated revenue.
(15) 
Effective dayrate represents the average dayrate multiplied by the average new generation utilization rate.

Non-GAAP Financial Measures
We disclose and discuss EBITDA as a non-GAAP financial measure in our public releases, including quarterly earnings releases, investor conference calls and other filings with the Commission. We define EBITDA as earnings (net income) before interest, income taxes, depreciation and amortization. Our measure of EBITDA may not be comparable to similarly titled measures presented by other companies. Other companies may calculate EBITDA differently than we do, which may limit their usefulness as comparative measures.
We view EBITDA primarily as a liquidity measure and, as such, we believe that the GAAP financial measure most directly comparable to this measure is cash flows provided by operating activities. Because EBITDA is not a measure of financial performance calculated in accordance with GAAP, it should not be considered in isolation or as a substitute for operating income, net income or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP.
EBITDA is widely used by investors and other users of our financial statements as a supplemental financial measure that, when viewed with our GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our ability to service debt, pay deferred taxes and fund drydocking charges and other maintenance capital expenditures. We also believe the disclosure of EBITDA helps investors meaningfully evaluate and compare our cash flow generating capacity from quarter to quarter and year to year.
EBITDA is also a financial metric used by management (i) as a supplemental internal measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; (ii) as a significant criteria for annual incentive cash bonuses paid to our executive officers and other shore-based employees; (iii) to compare to the EBITDA of other companies when evaluating potential acquisitions; and (iv) to assess our ability to service existing fixed charges and incur additional indebtedness.
