However, in cyclical industries such as ours, demand for our services rises and falls with the price of hydrocarbons, and in 2014, a number of industry issues converged to create a challenging market. First, over the past several years, offshore drilling companies ordered a large number of drilling units in anticipation of ever-increasing demand, which subsequently has yet to materialize. Then, as the units were delivered, oil companies reprioritized their capital efficiency plans and announced reductions to their capital spending budgets and delayed or canceled many of the projects expected to employ these new vessels. Marc Edwards President and Chief Executive Officer LETTER TO SHAREHOLDERS 72811rrdD2R1.indd 1 3/24/15 8:30 PM 2 | Finally, over the summer of 2014 oil prices 2 0 1 4 A N N U A L R E P O R T | D I A M O N D O F F S H O R E began to fall—benchmark pricing for oil fell more than 50% throughout the year—and operators responded by further reducing their exploration and development budgets. All of these factors have led to a dramatic shortage of contracting opportunities for newly delivered units, and we expect many more rigs across the industry to go idle during 2015 as they complete their existing contracts without the prospect for extensions or new work. At Diamond Offshore, we have long memories, and we understand the cyclical nature of our industry. While we certainly took advantage of the cycle by growing our fleet, we did so at a measured pace that allowed us to maintain a healthy balance sheet and pass our earnings on to shareholders through dividends. Since January of 2006, when Diamond Offshore began paying a special dividend to shareholders, we have paid total dividends of approximately $5.7 billion, or over $41 per share. This includes $3.50 per share paid by the Company in 2014. In light of current market conditions, our Board of Directors chose not to declare a special dividend in February 2015, but maintained a regular quarterly dividend of $0.125 per share. Given the weakness in industry fundamentals, we believe it is prudent to retain cash. Not paying a special dividend frees up $400 million per year that we can use to maximize capital flexibility and, if opportunities present themselves, to acquire assets at attractive values in this distressed market.

PRUDENTLY GROWING OUR FLEET Diamond Offshore took delivery of three newbuild drillships and two semisubmersible rigs in 2014, all of which had drilling contracts in place upon delivery. Our first newbuild drillship, the Ocean BlackHawk, began operating in the Gulf of Mexico in May 2014, and since then the rig’s crew has delivered best-in-class operating metrics for a “6th Generation” rig. In December, we took delivery of our second and third drillships, the Ocean BlackHornet and Ocean BlackRhino, which are now heading towards the Gulf of Mexico to commence their contracts. We plan to take delivery of our fourth and final newbuild drillship, the Ocean BlackLion, during the first quarter of 2015, and the rig should also begin working in the Gulf of Mexico later this year. It will be particularly advantageous for us to have all four of these units working in the same region, close to our corporate headquarters in Houston, Texas. The Gulf of Mexico is one of the lowest-cost offshore drilling markets in the world, and we are positioned to gain even greater economies of scale by having our personnel, spare parts and support infrastructure for the drillships centrally located here on the Gulf Coast. 72811rrdD2R1.indd 5 3/22/15 12:30 AM 6 | 2 0 1 4 A N N U A L R E P O R T | D I A M O N D O F F S H O R E OCEAN BLACKHAWK design GUSTO P10,000 DW year entered service 2014 location US GOM availability Q2 2019 water depths 12,000 FT drilling depth 40,000 FT 72811rrdD2R1.indd 6 3/24/15 8:02 PM 7 | T R O P E R L A U N N A 4 1 0 2 | E R O H S F F O D N O M A I D 72811rrdD2R1.indd 7 3/22/15 12:30 AM 8 | 2 0 1 4 A N N U A L R E P O R T | D I A M O N D O F F S H O R E 72811rrdD2R1.indd 8 3/22/15 12:30 AM OCEAN BLACKHORNET design GUSTO P10,000 DW year entered service 2014 location US GOM availability Q2 2020 water depths 12,000 FT drilling depth 40,000 FT 9 | T R O P E R L A U N N A 4 1 0 2 | E R O H S F F O D N O M A I D The recently delivered deepwater semisubmersible Ocean Onyx began its inaugural one-year contract in February 2014, and the rig is now on its way to its next job in Trinidad. In December, we took delivery of another deepwater semi- submersible, the Ocean Apex, which has begun an assignment in Vietnam. Additionally, our newbuild harsh environment semisubmersible, the Ocean GreatWhite, is scheduled for delivery in 2016, with its initial contract consisting of a three-year term off South Australia. Across the industry, a number of competitors’ newbuild rigs are being delivered without immediate prospects for work. For Diamond Offshore, however, all of our newbuild units are contracted at attractive rates into 2019 and beyond.

The decline in the price of oil has contributed to a dearth of opportunities for mid-water rigs across all geographic regions, and we expect newer rigs to compete aggressively against lower-spec units. As a result, several mid-water rigs in our fleet and across the industry may be cold stacked during 2015. Last year, we made the decision to retire and scrap six of these rigs, which had an average age of 37 years. Rig retirements such as these across the industry are one of several factors that should lead to a firming of the rig charter market in the future. 72811rrdD2R1.indd 9 3/24/15 8:29 PM OCEAN APEX design ODECO ENHANCED VICTORY CLASS year entered service 2014 location VIETNAM availability Q2 2015 water depths 6,000 FT drilling depth 30,000 FT 1 0 | 2 0 1 4 A N N U A L R E P O R T | D I A M O N D O F F S H O R E POSITIONING OUR FLEET FOR THE FUTURE Since 2009, Diamond Offshore has purchased, upgraded, built or ordered seven ultra-deepwater and two deepwater units, at a cost of more than $5 billion. These projects represent our ongoing process of fleet renewal and enhancement. We will continue to look for other opportunities to generate long-term value for shareholders, which in the current down cycle may take the form of distressed asset purchases, especially as we expect the weakness in our industry to persist. While we cannot predict the timing of a market recovery, we firmly believe that offshore drilling is necessary to meet the growing worldwide demand for hydrocarbons. Eventually, supply and demand will find equilibrium as our clients return to prioritizing production and reserve replacement. With our conservative capitalization and strong liquidity position, we are confident that the Company will be able to weather this downturn and emerge well positioned for the inevitable rebound.

General Diamond Offshore Drilling, Inc. is a leader in offshore drilling, providing contract drilling services to the energy industry around the globe with a fleet of 38 offshore drilling rigs, excluding three mid-water semisubmersible rigs that we plan to retire and scrap. Our fleet consists of 27 semisubmersibles, including the Ocean GreatWhite, which is under construction, six jack-ups and five dynamically positioned drillships, including the Ocean BlackLion which is also under construction. See “— Our Fleet — Fleet Enhancements and Additions” and “— Our Fleet — Fleet Status.” Unless the context otherwise requires, references in this report to “Diamond Offshore,” “we,” “us” or “our” mean Diamond Offshore Drilling, Inc. and our consolidated subsidiaries. We were incorporated in Delaware in 1989. Our Fleet Our diverse fleet enables us to offer a broad range of services worldwide in both the floater market (ultra-deepwater, deepwater and mid-water) and the non-floater, or jack-up, market. Floaters. A floater rig is a type of mobile offshore drilling unit that floats and does not rest on the seafloor. This asset class includes self-propelled drillships and semisubmersible rigs. Semisubmersible rigs consist of an upper working and living deck resting on vertical columns connected to lower hull members. Such rigs operate in a “semi-submerged” position, remaining afloat, off bottom, in a position in which the lower hull is approximately 55 feet to 90 feet below the water line and the upper deck protrudes well above the surface. Semisubmersibles hold position while drilling by use of a series of small propulsion units or thrusters that provide dynamic positioning, or DP, to keep the rig on location, or with anchors tethered to the sea bed. Although DP semisubmersibles are self-propelled, such rigs may be moved long distances with the assistance of tug boats. Non-DP, or moored, semisubmersibles require tug boats or the use of a heavy lift vessel to move between locations. A drillship is an adaptation of a maritime vessel which is designed and constructed to carry out drilling operations by means of a substructure with a moon pool centrally located in the hull. Drillships are typically self-propelled and are positioned over a drillsite through the use of either an anchoring system or a DP system similar to those used on semisubmersible rigs. Our floater fleet (semisubmersibles and drillships) can be further categorized based on the nominal water depth for each class of rig as follows: Category Rated Water Depth (a) (in feet) Number of Units in Our Fleet Ultra-Deepwater . . . . . . . . . . . 7,501 to 12,000 Deepwater . . . . . . . . . . . . . . . . . Mid-Water . . . . . . . . . . . . . . . . . 5,000 to 7,500 400 to 4,999 13 (b) 7 12 (a) Rated water depth for semisubmersibles and drillships reflects the maximum water depth in which a floating rig has been designed to operate. However, individual rigs are capable of drilling, or have drilled, in marginally greater water depths depending on various conditions (such as salinity of the ocean, weather and sea conditions). (b) Includes one drillship and one harsh environment semisubmersible rig under construction. See “— Fleet Enhancements and Additions” for further discussion of our rigs under construction. 2 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E Jack-ups. Jack-up rigs are mobile, self-elevating drilling platforms equipped with legs that are lowered to the ocean floor. Our jack-ups are used for drilling in water depths from 20 feet to 350 feet. The water depth limit in which a particular rig is able to operate is principally determined by the length of the rig’s legs. The rig hull includes the drilling equipment, jacking system, crew quarters, loading and unloading facilities, storage areas for bulk and liquid materials, heliport and other related equipment. A jack-up rig is towed to the drillsite with its hull riding in the sea, as a vessel, with its legs retracted. Once over a drillsite, the legs are lowered until they rest on the seabed and jacking continues with the legs penetrating the seabed until they are firm and stable, and resistance is sufficient to elevate the hull above the surface of the water. After completion of drilling operations, the hull is lowered until it rests in the water and then the legs are retracted for relocation to another drillsite. All of our jack-up rigs are equipped with a cantilever system that enables the rig to cantilever or extend its drilling package over the aft end of the rig. Fleet Enhancements and Additions. Our long-term strategy is to upgrade our fleet to meet customer demand for advanced, efficient and high-tech rigs by acquiring or building new rigs when possible to do so at attractive prices, and otherwise by enhancing the capabilities of our existing rigs at a lower cost and shortened construction period than newbuild construction would require. Since 2009, commencing with the acquisition of two newbuild, ultra-deepwater semisubmersible rigs, the Ocean Courage and Ocean Valor, we have committed over $5.0 billion towards upgrading our fleet. In late 2014, we took delivery of two ultra-deepwater drillships, the Ocean BlackHornet and Ocean BlackRhino. Contract preparation work is underway for both rigs, which are expected to commence drilling operations in the U.S. Gulf of Mexico, or GOM, in the second quarter of 2015. Construction of the Ocean Apex was completed late in the fourth quarter of 2014, and the rig is currently operating under a one-well contract in Vietnam. We also have two other construction projects underway. The following is a summary of our ongoing rig construction projects as of the date of this report: Rig Name Rig Type Estimated Cost (In millions) Expected Completion Contract Status Customer Location Ocean BlackLion . . . . . . . . . . . . . . Ultra-deepwater drillship Ocean GreatWhite . . . . . . . . . . . . Ultra-deepwater semisubmersible $655 $764 Q1 2015 Hess Corporation GOM Q1 2016 BP Australia We will evaluate further rig acquisition and enhancement opportunities as they arise. However, we can provide no assurance whether, or to what extent, we will continue to make rig acquisitions or enhancements to our fleet. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Cash Flow and Capital Expenditures” in Item 7 of this report. See “— Fleet Status” for more detailed information about our drilling fleet. Fleet Status The following table presents additional information regarding our floater fleet at February 9, 2015 (with certain subsequent developments described in the footnotes below): Rig Type and Name ULTRA-DEEPWATER: Semisubmersibles (8): Rated Water Depth (in feet) Attributes Year Built/ Redelivered (a) Current Location (b) Customer (c) Ocean GreatWhite . . . . . . . . . . . . . 10,000 DP; 6R; 15K Q1 2016 South Korea Under construction/BP (d) Ocean Valor . . . . . . . . . . . . . . . . . . . 10,000 DP; 6R; 15K Ocean Courage . . . . . . . . . . . . . . . . 10,000 DP; 6R; 15K 2009 2009 Brazil Brazil Petrobras Petrobras Ocean Confidence . . . . . . . . . . . . . 10,000 DP; 6R; 15K 2001/Q1 2015 Canary Islands Life-extension project/Actively Ocean Monarch . . . . . . . . . . . . . . . . 10,000 Ocean Endeavor . . . . . . . . . . . . . . . 10,000 Ocean Rover . . . . . . . . . . . . . . . . . . .

From time to time our fleet operates in various other markets throughout the world. See Note 16 “Segments and Geographic Area Analysis” to our Consolidated Financial Statements in Item 8 of this report. Offshore Contract Drilling Services Our contracts to provide offshore drilling services vary in their terms and provisions. We typically obtain our contracts through a competitive bid process, although it is not unusual for us to be awarded drilling contracts following direct negotiations. Our drilling contracts generally provide for a basic fixed dayrate regardless of whether or not such drilling results in a productive well. Drilling contracts may also provide for reductions in rates during periods when the rig is being moved or when drilling operations are interrupted or restricted by equipment breakdowns, adverse weather conditions or other circumstances. Under dayrate contracts, we generally pay the operating expenses of the rig, including wages and the cost of incidental supplies. Historically, dayrate contracts have accounted for the majority of our revenues. In addition, from time to time, our dayrate contracts may also provide for the ability to earn an incentive bonus from our customer based upon performance. The duration of a dayrate drilling contract is generally tied to the time required to drill a single well or a group of wells, in what we refer to as a well-to-well contract, or a fixed period of time, in what we refer to as a term contract. Many drilling contracts may be terminated by the customer in the event the drilling unit is destroyed or lost, or if drilling operations are suspended for an extended period of time as a result of a breakdown of equipment or, in some cases, due to events beyond the control of either party to the contract. Certain of our contracts also permit the customer to terminate the contract early by giving notice; in most circumstances this requires the payment of an early termination fee by the customer. The contract term in many instances may also be extended by the customer exercising options for the drilling of additional wells or for an additional length of time, generally at competitive market rates and mutually agreeable terms at the time of the extension. See “Risk Factors — Our business involves numerous operating hazards that could expose us to significant losses and significant damage claims. We are not fully insured against all of these risks and our contractual indemnity provisions may not fully protect us,” “Risk Factors — The terms of our drilling contracts may limit our ability to attain profitability in a declining market or to benefit from increasing dayrates in an improving market,” “Risk Factors— We can provide no assurance that our drilling contracts will not be terminated early or that our current backlog of contract drilling revenue will be ultimately realized,” “Risk Factors— We may enter into drilling contracts that expose us to greater risks than we normally assume” and “Risk Factors — We self-insure for physical damage to rigs and equipment caused by named windstorms in the U.S. Gulf of Mexico” in Item 1A of this report, which are incorporated herein by reference.

During 2014, 2013 and 2012, we performed services for 35, 39 and 35 different customers, respectively. During 2014, 2013 and 2012, one of our customers in Brazil, Petróleo Brasileiro S.A., or Petrobras (a Brazilian multinational energy company that is majority-owned by the Brazilian government), accounted for 32%, 34% and 33% of our annual total consolidated revenues, respectively. OGX Petróleo e Gás Ltda., or OGX (a privately owned Brazilian oil and natural gas company that filed for bankruptcy in October 2013), accounted for 2% and 12% of our annual total consolidated revenues for the years ended December 31, 2013 and 2012, respectively. We did not perform any contract drilling services for OGX in 2014. No other customer accounted for 10% or more of our annual total consolidated revenues during 2014, 2013 or 2012. See “Risk Factors — Our industry is highly competitive, with oversupply and intense price competition” in Item 1A of this report, which is incorporated herein by reference. We have six rigs currently contracted offshore Brazil and all four of our newbuild drillships are currently operating, or expected to begin drilling operations, during 2015 in the GOM. Our contract backlog attributable to our expected operations offshore Brazil is $607.0 million, $395.0 million, $332.0 million and $159.0 million for the years 2015, 2016, 2017 and 2018, respectively. Our contract backlog attributable to our expected operations in the GOM is $505.0 million, $523.0 million and $653.0 million for the years 2015, 2016 and 2017, respectively, and $1.2 billion in the aggregate for the years 2018 to 2020 attributable to four customers. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Market Overview — Contract Drilling Backlog” in Item 7 of this report. See “Risk Factors — We can provide no assurance that our drilling contracts will not be terminated early or that our current backlog of contract drilling revenue will be ultimately realized” in Item 1A of this report, which is incorporated herein by reference. Competition Despite consolidation in previous years, the offshore contract drilling industry remains highly competitive with numerous industry participants, none of which at the present time has a dominant market share. The industry may also experience additional consolidation in the future, which could create other large competitors. Some of our competitors may have greater financial or other resources than we do. We compete with offshore drilling contractors that together have approximately 800 mobile drilling rigs, including approximately 300 floater rigs, marketed worldwide. The offshore contract drilling industry is influenced by a number of factors, including global economies and demand for oil and natural gas, current and anticipated prices of oil and natural gas, expenditures by oil and gas companies for exploration and development of oil and natural gas and the availability of drilling rigs. Drilling contracts are traditionally awarded on a competitive bid basis. Price is typically the primary factor in determining which qualified contractor is awarded a job. Customers may also consider rig availability and location, a drilling contractor’s operational and safety performance record, and condition and suitability of equipment. We believe we compete favorably with respect to these factors. We compete on a worldwide basis, but competition may vary significantly by region at any particular time. See “— Markets.” Competition for offshore rigs generally takes place on a global basis, as these rigs are highly mobile and may be moved, at a cost that may be substantial, from one region to another. It is characteristic of the offshore contract drilling industry to move rigs from areas of low utilization and dayrates to areas of greater activity and relatively higher dayrates. Significant new rig construction and upgrades of existing drilling units could also intensify price competition. See “Risk Factors — Our industry is highly competitive, with oversupply and intense price competition” in Item 1A of this report, which is incorporated herein by reference. Governmental Regulation Our operations are subject to numerous international, foreign, U.S., state and local laws and regulations that relate directly or indirectly to our operations, including regulations controlling the discharge of materials into the environment, requiring removal and clean-up under some circumstances, or otherwise relating to the protection of the environment, and may include laws or regulations pertaining to climate change, carbon emissions or energy use. See “Risk Factors — Governmental laws and regulations, both domestic and international, may add to our costs or limit our drilling activity” and “Risk Factors — Compliance with or breach of environmental laws can be costly and could limit our operations” in Item 1A of this report, which are incorporated herein by reference. Operations Outside the United States Our operations outside the U.S. accounted for approximately 85%, 89% and 94% of our total consolidated revenues for the years ended December 31, 2014, 2013 and 2012, respectively. See “Risk Factors — Significant portions of our operations are conducted outside the United States and involve additional risks not associated with United States domestic operations,” “Risk Factors — We may enter into drilling contracts that expose us to greater risks than we normally assume,” “Risk Factors — We may be required to accrue additional tax liability on certain of our foreign earnings” and “Risk Factors — Fluctuations in exchange rates and nonconvertibility of currencies could result in losses to us” in Item 1A of this 7 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I report, which are incorporated herein by reference.

Our business is subject to a variety of risks, including the risks described below. You should carefully consider these risks when evaluating us and our securities. The risks and uncertainties described below are not the only ones facing our company. We are also subject to a variety of risks that affect many other companies generally, as well as additional risks and uncertainties not known to us or that, as of the date of this report, we believe are not as significant as the risks described below. If any of the following risks actually occur, our business, financial condition, results of operations and cash flows, and the trading prices of our securities, may be materially and adversely affected. The worldwide demand for drilling services significantly declined as a result of the decline in oil prices during the second half of 2014. Demand for our drilling services depends in large part upon oil and natural gas industry offshore exploration and production activity and expenditure levels, which are directly affected by oil and gas prices and market expectations of potential changes in oil and gas prices. Oil prices declined precipitously during the second half of 2014, which caused a decline in the demand for offshore drilling services. Any prolonged substantial reduction in oil and gas prices would adversely affect demand for the services we provide. A prolonged substantial reduction in demand for our drilling services as a result of a decline in oil prices could have a material adverse effect on our financial condition, results of operations and cash flows. Oil prices have been, and are expected to continue to be, volatile and are affected by numerous factors beyond our control, including: (cid:129) worldwide supply and demand for oil and gas; (cid:129) the level of economic activity in energy-consuming markets; (cid:129) the worldwide economic environment or economic trends, such as recessions; (cid:129) the ability of the Organization of Petroleum Exporting Countries (OPEC) to set and maintain production levels and pricing; (cid:129) the level of production in non-OPEC countries; (cid:129) civil unrest and the worldwide political and military environment, including uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities involving the Middle East, Russia, other oil- producing regions or other geographic areas or further acts of terrorism in the United States or elsewhere; (cid:129) the cost of exploring for, developing, producing and delivering oil and gas; (cid:129) the discovery rate of new oil and gas reserves; (cid:129) the rate of decline of existing and new oil and gas reserves and production; (cid:129) available pipeline and other oil and gas transportation and refining capacity; (cid:129) the ability of oil and gas companies to raise capital; 9 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I (cid:129) weather conditions, including hurricanes, which can affect oil and gas operations over a wide area; (cid:129) natural disasters or incidents resulting from operating hazards inherent in offshore drilling, such as oil spills; (cid:129) the policies of various governments regarding exploration and development of their oil and gas reserves; (cid:129) technological advances affecting energy consumption, including development and exploitation of alternative fuels or energy sources; (cid:129) laws and regulations relating to environmental or energy security matters, including those purporting to address global climate change; (cid:129) domestic and foreign tax policy; and (cid:129) advances in exploration and development technology. An increase in commodity demand and prices will not necessarily result in an immediate increase in offshore drilling activity since our customers’ project development times, reserve replacement needs, expectations of future commodity demand, prices and supply of available competing rigs all combine to affect demand for our rigs. Our business depends on the level of activity in the oil and gas industry, which has been cyclical and is significantly affected by many factors outside of our control. Demand for our drilling services depends upon the level of offshore oil and gas exploration, development and production in markets worldwide, and those activities depend in large part on oil and gas prices, worldwide demand for oil and gas and a variety of political and economic factors. The level of offshore drilling activity may also be adversely affected if operators reduce or defer new investment in offshore projects, reduce or suspend their drilling budgets or reallocate their drilling budgets away from offshore drilling in favor of other priorities, such as shale or other land-based projects, which could reduce demand for our rigs and newbuilds. As a result, our business and the oil and gas industry in general are subject to cyclical fluctuations. As a result of the cyclical fluctuations in the market, there have been periods of lower demand, excess rig supply and lower dayrates, followed by periods of higher demand, shorter rig supply and higher dayrates. We cannot predict the 1 0 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E timing or duration of such fluctuations. Periods of lower demand or excess rig supply intensify the competition in the industry and often result in periods of lower utilization and lower dayrates. During these periods, our rigs may not obtain contracts for future work and may be idle for long periods of time or may be able to obtain work only under contracts with lower dayrates or less favorable terms, which could have a material adverse effect on our financial condition, results of operations and cash flows. Additionally, prolonged periods of low utilization and dayrates could also result in the recognition of impairment charges on certain of our drilling rigs if future cash flow estimates, based upon information available to management at the time, indicate that the carrying value of these rigs may not be recoverable. See “— We may incur asset impairments and/or rig retirements as a result of declining demand for certain offshore drilling rigs.” We may not be able to renew or replace expiring contracts for our rigs. We have a number of customer contracts that will expire in 2015 and 2016. Our ability to renew or replace expiring contracts or obtain new contracts, and the terms of any such contracts, will depend on various factors, including market conditions and the specific needs of our customers. Given the highly competitive and historically cyclical nature of our industry, we may be required to renew or replace expiring contracts or obtain new contracts at dayrates that are below, and potentially substantially below, existing dayrates, or that have terms that are less favorable to us than our existing contracts or we may be unable to secure contracts for these rigs. This could have a material adverse effect on our financial condition, results of operations and cash flows. We can provide no assurance that our drilling contracts will not be terminated early or that our current backlog of contract drilling revenue will be ultimately realized. Generally, our customers may terminate our term drilling contracts under certain circumstances, such as if the drilling rig is destroyed or lost, if we suspend drilling operations for a specified period of time as a result of a breakdown of major equipment, excessive downtime for repairs, failure to meet minimum performance criteria or, in some cases, due to other events beyond the control of either party. In addition, some of our drilling contracts permit the customer to terminate the contract after specified notice periods, often by tendering contractually specified termination amounts, which may not fully compensate us for the loss of the contract. In some cases, because of depressed market conditions or commodity prices, restricted credit markets, economic downturns, changes in priorities or strategy or other factors beyond our control, a customer may no longer want or need a rig that is currently under contract or may be able to obtain a comparable rig at a lower dayrate. For these reasons, customers may seek to renegotiate the terms of our existing drilling contracts, terminate our contracts without justification or repudiate or otherwise fail to perform their obligations under our contracts. When a customer terminates our contract prior to the contract’s scheduled expiration, our contract backlog is adversely impacted, and we might not recover any compensation for the termination or any recovery we might obtain may not fully compensate us for the loss of the contract. In any case, the early termination of a contract may result in our rig being idle for an extended period of time. Each of these results could have a material adverse effect on our financial condition, results of operations and cash flows. In addition, if our customer cancels our contract or if we elect to terminate a contract due to the customer’s nonperformance and in either case we are unable to secure a new contract on a timely basis and on substantially similar terms, or if a contract is disputed or suspended for an extended period of time or if a contract is renegotiated, it could materially and adversely affect our financial condition, results of operations and cash flows. Generally, our contract backlog only includes future revenues under firm commitments; however, from time to time, we may report anticipated commitments for which definitive agreements have not yet been, but are expected to be, executed. We can provide no assurance that in such cases we will be able to ultimately execute a definitive agreement. In addition, for the reasons described above, we can provide no assurance that our customers will be willing or able to fulfill their contractual commitments to us. Our inability to perform under our contractual obligations or to execute definitive agreements, or our customers’ inability or unwillingness to fulfill their contractual commitments to us, may have a material adverse effect on our financial condition, results of operations and cash flows. See “— Our industry is highly competitive, with oversupply and 1 1 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I intense price competition” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Market Overview — Contract Drilling Backlog” in Item 7 of this report. Our industry is highly competitive, with oversupply and intense price competition. The offshore contract drilling industry is highly competitive with numerous industry participants. Some of our competitors may be larger companies, have larger fleets and have greater financial or other resources than we do. The drilling industry has experienced consolidation in the past and may experience additional consolidation, which could create additional large competitors. Drilling contracts are traditionally awarded on a competitive bid basis. Price is typically the primary factor in determining which qualified contractor is awarded a job; however, rig availability and location, a drilling contractor’s safety record and the quality and technical capability of service and equipment may also be considered. Recent new rig construction and upgrades of existing drilling rigs, as well as established rigs coming off contract during 2014, have contributed to the current decline in rig utilization, intensifying price competition. Additional newbuild rigs entering the market are expected to further negatively impact rig utilization and intensify price competition as scheduled delivery dates occur. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Market Overview — Impact of Newbuild Rigs and Other Challenges of the Offshore Drilling Industry “ in Item 7 of this report. In Brazil, Petrobras has announced plans to construct locally 29 new ultra-deepwater drilling rigs to be delivered beginning in 2015. These new drilling rigs, if built, would increase rig supply and could intensify price competition in Brazil as well as other markets as they are placed in service, would compete with, and could displace, both our deepwater and ultra-deepwater floaters coming off contract as well as our newbuilds coming to market and could materially adversely affect our utilization rates, particularly in Brazil. We provide offshore drilling services to a customer base that includes major and independent oil and gas companies and government-owned oil companies. During 2014, one of our customers in Brazil, Petrobras, and our five largest customers in the aggregate accounted for 32% and 61%, respectively, of our annual total consolidated revenues. The loss of a significant customer could have a material adverse impact on our financial condition, results of operations and cash flows. In addition, if a significant customer experiences liquidity constraints or other financial difficulties, it could materially adversely affect our utilization rates in the affected market and also displace demand for our other drilling rigs and newbuilds as the resulting excess supply enters the market. While it is normal for our customer base to change over time as work programs are completed, the loss of, or a significant reduction in the number of rigs contracted with, any major customer may have a material adverse effect on our financial condition, results of operations and cash flows. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Market Overview — Contract Drilling Backlog” in Item 7 of this report. We may incur asset impairments and/or rig retirements as a result of declining demand for certain offshore drilling rigs. Periods of excess rig supply intensify the competition in the industry and often result in rigs being idled and in some cases retired and/or scrapped. Presently, there are numerous recently constructed ultra-deepwater vessels and high- specification jackups that have entered the market and additional units are contracted for delivery over the next several years. The entry into service of these new units will continue to increase rig supply. The deepwater market has recently seen a decrease in marketed utilization. Any further increases in construction of new units will increase the negative impact on utilization. We evaluate our property and equipment for impairment whenever changes in circumstances indicate that the carrying amount of an asset may not be recoverable, and we could incur impairment charges related to the carrying value of our drilling rigs. Impairment write-offs could result if, for example, any of our rigs become obsolete or commercially less desirable or their carrying values become excessive due to the condition of the rig, cold stacking the rig, the expectation of cold stacking the rig in the near future, a decision to retire or scrap the rig, changes in technology, 1 2 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E market demand or market expectations, or excess spending over budget on a new-build construction project or major rig upgrade. We utilize an undiscounted probability-weighted cash flow analysis in testing an asset for potential impairment, reflecting management’s assumptions and estimates regarding the appropriate risk-adjusted dayrate by rig, future industry conditions and operations and other factors. Asset impairment evaluations are, by their nature, highly subjective. The use of different estimates and assumptions could result in materially different carrying values of our assets, which could impact the need to record an impairment charge and the amount of any charge taken. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Market Overview — Critical Accounting Estimates — Property, Plant and Equipment” in Item 7 of this report and Note 2 “Asset Impairments” to our Consolidated Financial Statements in Item 8 of this report. We can provide no assurance that our assumptions and estimates used in our asset impairment evaluations will ultimately be realized or that the current carrying value of our property and equipment, including rigs designated as held for sale, will ultimately be realized. Although we have paid cash dividends in the past, we will not pay a special dividend in the first quarter of 2015, we may not pay regular or special cash dividends in the future and we can give no assurance as to the amount or timing of the payment of any future regular or special cash dividends. We pay dividends at the discretion of our Board of Directors. In February 2015, our Board of Directors declared a regular quarterly dividend of $0.125 per share, but chose not to declare a special dividend. If in the future our Board continues to decide not to pay any special cash dividends or pay special cash dividends less frequently or in smaller amounts, it could have a negative effect on the market price of our common stock. Our Board has adopted a policy of considering regular and special cash dividends, in amounts to be determined, on a quarterly basis. Any determination to declare a dividend, as well as the amount of any dividend that may be declared, will be based on the Board’s consideration of our financial position, earnings, earnings outlook, capital spending plans, outlook on current and future market conditions and business needs and other factors that our Board considers relevant factors at that time. The Board’s dividend policy may change from time to time, but there can be no assurance that we will declare any cash dividends at all or in any particular amounts. See “Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities — Dividend Policy” in Item 5 of this report and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources” in Item 7 of this report. The terms of our drilling contracts may limit our ability to attain profitability in a declining market or to benefit from increasing dayrates in an improving market. The duration of offshore drilling contracts is generally determined by customer requirements and, to a lesser extent, the respective management strategies of the offshore drilling contractors. In periods of decreasing demand for offshore rigs, drilling contractors may prefer longer term contracts to preserve dayrates at existing levels and ensure utilization, while customers may prefer shorter contracts that allow them to more quickly obtain the benefit of declining dayrates. Moreover, drilling contractors may accept lower dayrates in a declining market in order to obtain longer-term contracts and add backlog. Conversely, in periods of rising demand for offshore rigs, contractors may prefer shorter contracts that allow them to more quickly profit from increasing dayrates, while customers with reasonably definite drilling programs may prefer longer term contracts to maintain dayrate prices at a consistent level. We may be exposed to decreasing dayrates if any of our rigs are working under short-term contracts during a declining market. Likewise, if any of our rigs are committed under long-term contracts during an improving market, we may be unable to enjoy the benefit of rising dayrates for the duration of those contracts. Exposure to falling dayrates in a declining market or the inability to fully benefit from increasing dayrates in an improving market through shorter term contracts may limit our profitability. 3 1 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I We may enter into drilling contracts that expose us to greater risks than we normally assume. From time to time, we may enter into drilling contracts with national oil companies, government-controlled entities or others that expose us to greater risks than we normally assume, such as exposure to greater environmental or other liability and more onerous termination provisions giving the customer a right to terminate without cause or upon little or no notice. Upon termination, these contracts may not result in a payment to us, or if a termination payment is required, it may not fully compensate us for the loss of a contract. In addition, the early termination of a contract may result in a rig being idle for an extended period of time, which could adversely affect our financial condition, results of operations and cash flows. While we believe that the financial terms of these contracts and our operating safeguards in place may partially mitigate these risks, we can provide no assurance that the increased risk exposure will not have a material negative impact on our future operations or financial results. Changes in tax laws, effective income tax rates or adverse outcomes resulting from examination of our tax returns could adversely affect our financial results. Tax laws and regulations are highly complex and subject to interpretation and disputes. We conduct our worldwide operations through various subsidiaries in a number of countries throughout the world. As a result, we are subject to highly complex tax laws, regulations and income tax treaties within and between the countries in which we operate as well as countries in which we may be resident, which may change and are subject to interpretation. We determine our income tax expense based on our interpretation of the applicable tax laws and regulations in effect in each jurisdiction for the period during which we operate and earn income. Our overall effective tax rate could be adversely and suddenly affected by lower than anticipated earnings in countries where we have lower statutory rates and higher than anticipated earnings in countries where we have higher statutory rates, by changes in the valuation of our deferred tax assets and liabilities or by changes in tax law, tax treaties, regulations, accounting principles or interpretations thereof in one or more countries in which we operate. In addition, changes in laws, treaties and regulations and the interpretation of such laws, treaties and regulations may put us at risk for future tax assessments and liabilities which could be substantial and could have a material adverse effect on our financial condition, results of operations and cash flows. Our income tax returns are subject to review and examination. We do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges any tax position taken or intercompany pricing policies, or if the terms of certain income tax treaties are interpreted in a manner that is adverse to us or our operations, or if we lose a material tax dispute in any country, our effective tax rate on our worldwide earnings could increase substantially and our earnings and cash flows from operations could be materially adversely affected. Governmental laws and regulations, both domestic and international, may add to our costs or limit our drilling activity. Our operations are affected from time to time in varying degrees by governmental laws and regulations. In addition to the specific regulatory risks discussed elsewhere in this Item 1A. “Risk Factors” section, our operations are subject to other laws, regulations and government policies worldwide. Certain countries are subject to restrictions, sanctions and embargoes imposed by the United States government or other governmental or international authorities. These restrictions, sanctions and embargoes may prohibit or limit us from participating in certain business activities in those countries. Our operations are also subject to numerous local, state and federal laws and regulations in the United States and in foreign jurisdictions concerning the containment and disposal of hazardous materials, the remediation of contaminated properties and the protection of the environment. The offshore drilling industry is dependent on demand for services from the oil and gas exploration industry and, accordingly, can be affected by changes in tax and other laws relating to the energy business generally. We may be required to make significant expenditures for additional capital equipment or inspections and recertifications thereof to comply with existing or new governmental laws and regulations. It is also possible that these laws and regulations may in the future add significantly to our operating costs or result in a 1 4 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E reduction in revenues associated with downtime required to install such equipment or may otherwise significantly limit drilling activity. In addition, our operating income is negatively impacted when we perform certain regulatory inspections, which we refer to as a 5-year survey, or special survey, that are due every five years for each of our rigs. These special surveys are generally performed in a shipyard and require scheduled downtime, which can negatively impact operating revenue. Operating expenses increase as a result of these special surveys due to the cost to mobilize the rigs to a shipyard, inspection costs incurred and repair and maintenance costs. Repair and maintenance activities may result from the special survey or may have been previously planned to take place during this mandatory downtime. The number of rigs undergoing a 5-year survey will vary from year to year, as well as from quarter to quarter. Operating income may also be negatively impacted by intermediate surveys, which are performed at interim periods between 5-year surveys. Intermediate surveys are generally less extensive in duration and scope than a 5-year survey. Although an intermediate survey normally does not require shipyard time, the survey may require some downtime for the rig. We can provide no assurance as to the exact timing and/or duration of downtime associated with regulatory inspections, planned rig mobilizations and other shipyard projects. In the aftermath of the 2010 Macondo well blowout and subsequent investigation into the causes of the event, new rules were implemented for oil and gas operations in the GOM and in many of the international locations in which we operate, including new standards for well design, casing and cementing and well control procedures, equipment inspection and certifications, as well as rules requiring operators to systematically identify risks and establish safeguards against those risks through a comprehensive safety and environmental management system, or SEMS. New regulations may continue to be announced, including rules regarding drilling systems and equipment, such as blowout preventer and well control systems and lifesaving systems, as well as rules regarding employee training, engaging personnel in safety management and requiring third party audits of SEMS programs. Such new regulations could require modifications or enhancements to existing systems and equipment, or require new equipment, and could increase our operating costs and cause downtime for our rigs if we are required to take any of them out of service between scheduled surveys or inspections, or if we are required to extend scheduled surveys or inspections, to meet any such new requirements. We are not able to predict the likelihood, nature or extent of additional rulemaking, and we are not able to predict the future impact of these events on our operations. Additional governmental regulations concerning licensing, taxation, equipment specifications, training requirements or other matters could increase the costs of our operations, and enhanced permitting requirements, as well as escalating costs borne by our customers, could reduce exploration activity in the GOM and therefore demand for our services. Governments in some countries are increasingly active in regulating and controlling the ownership of concessions, the exploration for oil and gas and other aspects of the oil and gas industry. The modification of existing laws or regulations or the adoption of new laws or regulations curtailing exploratory or developmental drilling for oil and gas for economic, environmental or other reasons could materially and adversely affect our operations by limiting drilling opportunities. Governments around the world are also increasingly considering and adopting laws and regulations to address climate change issues. Lawmakers and regulators in the United States and other jurisdictions where we operate have focused increasingly on restricting the emission of carbon dioxide, methane and other “greenhouse” gases. This may result in new environmental regulations that may unfavorably impact us, our suppliers and our customers. We may be exposed to risks related to new laws, regulations, treaties or international agreements pertaining to climate change, greenhouse gases, carbon emissions or energy use that could decrease the use of oil or natural gas, thus reducing demand for hydrocarbon-based fuel and our drilling services. Governments may also pass laws or regulations incentivizing or mandating the use of alternative energy sources, such as wind power and solar energy, which may reduce demand for oil and natural gas and our drilling services. Such laws, regulations, treaties or international agreements could result in increased compliance costs or additional operating restrictions, which may have a negative impact on our business, and could adversely affect our operations by limiting drilling opportunities. Contracts for our drilling rigs are generally fixed dayrate contracts, and increases in our operating costs could adversely affect our profitability on those contracts. Our contracts for our drilling rigs generally provide for the payment of a fixed dayrate per rig operating day, although some contracts do provide for a limited escalation in dayrate due to increased operating costs we incur on the project. Many of our operating costs, such as labor costs, are unpredictable and fluctuate based on events beyond our control. In addition, equipment repair and maintenance expenses fluctuate depending on the type of activity the rig is performing, the age and condition of the equipment and general market factors impacting relevant parts, components and services. The gross margin that we realize on these fixed dayrate contracts will fluctuate based on variations in our operating costs over the terms of the contracts. In addition, for contracts with dayrate escalation clauses, we may not be able to fully recover increased or unforeseen costs from our customers. Our inability to recover these increased or unforeseen costs from our customers could materially and adversely affect our financial condition, results of operations and cash flows. Rig conversions, upgrades or new-builds may be subject to delays and cost overruns. From time to time, we add new capacity through conversions or upgrades to our existing rigs or through new construction, such as our ultra-deepwater drillship, Ocean BlackLion, and our harsh environment, ultra-deepwater semisubmersible rig, Ocean GreatWhite, both currently under construction. Projects of this type are subject to risks of delay or cost overruns inherent in any large construction project resulting from numerous factors, including the 5 1 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I following: (cid:129) shortages of equipment, materials or skilled labor; (cid:129) work stoppages; (cid:129) unscheduled delays in the delivery of ordered materials and equipment; (cid:129) unanticipated cost increases or change orders; (cid:129) weather interferences or storm damage; (cid:129) difficulties in obtaining necessary permits or in meeting permit conditions; (cid:129) design and engineering problems; (cid:129) disputes with shipyards or suppliers; (cid:129) availability of suppliers to recertify equipment for enhanced regulations; (cid:129) customer acceptance delays; (cid:129) shipyard failures or unavailability; and (cid:129) failure or delay of third party service providers, civil unrest and labor disputes. Failure to complete a rig upgrade or new construction on time, or failure to complete a rig conversion or new construction in accordance with its design specifications may, in some circumstances, result in the delay, renegotiation or cancellation of a drilling contract, resulting in a loss of contract drilling backlog and revenue to us. If a drilling contract is terminated under these circumstances, we may not be able to secure a replacement contract or, if we do secure a replacement contract, it may not contain equally favorable terms. 1 6 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E Our business involves numerous operating hazards that could expose us to significant losses and significant damage claims. We are not fully insured against all of these risks and our contractual indemnity provisions may not fully protect us. Our operations are subject to the significant hazards inherent in drilling for oil and gas offshore, such as blowouts, reservoir damage, loss of production, loss of well control, unstable or faulty sea floor conditions, fires and natural disasters such as hurricanes. The occurrence of any of these types of events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury or death to rig personnel, damage to producing or potentially productive oil and gas formations, and oil spillage, oil leaks, well blowouts and extensive uncontrolled fires, any of which could cause significant environmental damage. In addition, offshore drilling operations are subject to marine hazards, including capsizing, grounding, collision and loss or damage from severe weather. Operations also may be suspended because of machinery breakdowns, abnormal drilling conditions, failure of suppliers or subcontractors to perform or supply goods or services or personnel shortages. Any of the foregoing events could result in significant damage or loss to our properties and assets or the properties and assets of others, injury or death to rig personnel or others, significant loss of revenues and significant damage claims against us, which could have a material adverse effect on our results of operations, financial condition and cash flows. Our drilling contracts with our customers provide for varying levels of indemnity and allocation of liabilities between our customers and us with respect to the hazards and risks inherent in, and damages or losses arising out of, our operations, and we may not be fully protected. Our contracts with our customers generally provide that we and our customers each assume liability for our respective personnel and property. Our contracts also generally provide that our customers assume most of the responsibility for and indemnify us against loss, damage or other liability resulting from, among other hazards and risks, pollution originating from the well and subsurface damage or loss, while we typically retain responsibility for and indemnify our customers against pollution originating from the rig. However, in certain drilling contracts we may not be fully indemnified by our customers for damage to their property and/or the property of their other contractors. In certain contracts we may assume liability for losses or damages (including punitive damages) resulting from pollution or contamination caused by negligent or willful acts of commission or omission by us, our suppliers and/or subcontractors, generally subject to negotiated caps on a per occurrence basis and/or on an aggregate basis for the term of the contract. In some cases, suppliers or subcontractors who provide equipment or services to us may seek to limit their liability resulting from pollution or contamination. Our contracts are individually negotiated, and the levels of indemnity and allocation of liabilities in them can vary from contract to contract depending on market conditions, particular customer requirements and other factors existing at the time a contract is negotiated. Additionally, the enforceability of indemnification provisions in our contracts may be limited or prohibited by applicable law or may not be enforced by courts having jurisdiction, and we could be held liable for substantial losses or damages and for fines and penalties imposed by regulatory authorities. The indemnification provisions of our contracts may be subject to differing interpretations, and the laws or courts of certain jurisdictions may enforce such provisions while other laws or courts may find them to be unenforceable, void or limited by public policy considerations, including when the cause of the underlying loss or damage is our gross negligence or willful misconduct, when punitive damages are attributable to us or when fines or penalties are imposed directly against us. The law with respect to the enforceability of indemnities varies from jurisdiction to jurisdiction and is unsettled under certain laws that are applicable to our contracts. Current or future litigation in particular jurisdictions, whether or not we are a party, may impact the interpretation and enforceability of indemnification provisions in our contracts. There can be no assurance that our contracts with our customers, suppliers and subcontractors will fully protect us against all hazards and risks inherent in our operations. There can also be no assurance that those parties with contractual obligations to indemnify us will be financially able to do so or will otherwise honor their contractual obligations. We maintain liability insurance, which includes coverage for environmental damage; however, because of contractual provisions and policy limits, our insurance coverage may not adequately cover our losses and claim costs. In addition, certain risks such as pollution, reservoir damage and environmental risks are generally not fully insurable. Also, we do not typically purchase loss-of-hire insurance to cover lost revenues when a rig is unable to work. Moreover, insurance costs across the industry have increased following the Macondo incident and, in the future, certain insurance coverage may become more costly and less available or not available at all. Accordingly, it is possible that our losses from the hazards we face could have a material adverse effect on our results of operations, financial condition and cash flows. We believe that the policy limit under our marine liability insurance is within the range that is customary for companies of our size in the offshore drilling industry and is appropriate for our business. However, if an accident or other event occurs that exceeds our coverage limits or is not an insurable event under our insurance policies, or is not fully covered by contractual indemnity, it could have a material adverse effect on our results of operations, financial condition and cash flows. There can be no assurance that we will continue to carry the insurance we currently maintain, that our insurance will cover all types of losses or that we will be able to maintain adequate insurance in the future at rates we consider to be reasonable or that we will be able to obtain insurance against some risks. Accordingly, the occurrence of any of the hazards we face could have a material adverse effect on our results of operations, financial condition and cash flows. 7 1 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Significant portions of our operations are conducted outside the United States and involve additional risks not associated with United States domestic operations. Our operations outside the United States accounted for approximately 85%, 89% and 94% of our total consolidated revenues for 2014, 2013 and 2012, respectively, and include operations in South America, Australia and Southeast Asia, the Middle East, Europe, East and West Africa, the Mediterranean and Mexico. Because we operate in various regions throughout the world, we are exposed to risks of war, political disruption, civil disturbance, acts of terrorism, political corruption, possible economic and legal sanctions (such as possible restrictions against countries that the U.S. government may consider to be state sponsors of terrorism) and changes in global trade policies. We may not have insurance coverage for these risks, or we may not be able to obtain adequate insurance coverage for such events at reasonable rates. Our operations may become restricted, disrupted or prohibited in any country in which any of the foregoing risks occur. In particular, the occurrence of any of these risks or any of the following events could materially and adversely impact our results of operations: (cid:129) political and economic instability; (cid:129) piracy, terrorism or other assaults on property or personnel; (cid:129) kidnapping of personnel; (cid:129) seizure, expropriation, nationalization, deprivation, malicious damage or other loss of possession or use of property or equipment; (cid:129) renegotiation or nullification of existing contracts; (cid:129) disputes and legal proceedings in international jurisdictions; (cid:129) changing social, political and economic conditions; (cid:129) enactment of additional or stricter U.S. government or international sanctions; (cid:129) imposition of wage and price controls, trade barriers or import-export quotas; (cid:129) restrictive foreign and domestic monetary policies; (cid:129) the inability to repatriate income or capital; 1 8 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E (cid:129) difficulties in collecting accounts receivable and longer collection periods; (cid:129) fluctuations in currency exchange rates and restrictions on currency exchange; (cid:129) regulatory or financial requirements to comply with foreign bureaucratic actions; (cid:129) restriction or disruption of business activities; (cid:129) limitation of our access to markets for periods of time; (cid:129) travel limitations or operational problems caused by public health threats; (cid:129) difficulties in supplying, repairing or replacing equipment or transporting personnel in remote locations; (cid:129) difficulties in obtaining visas or work permits for our employees on a timely basis; and (cid:129) changing taxation policies and confiscatory or discriminatory taxation. We are also subject to the U.S. Treasury Department’s Office of Foreign Assets Control and other U.S. laws and regulations governing our international operations in addition to worldwide anti-bribery laws. In addition, international contract drilling operations are subject to various laws and regulations in countries in which we operate, including laws and regulations relating to: (cid:129) the equipping and operation of drilling rigs; (cid:129) import-export quotas or other trade barriers; (cid:129) repatriation of foreign earnings or capital; (cid:129) oil and gas exploration and development; (cid:129) local content requirements; (cid:129) taxation of offshore earnings and earnings of expatriate personnel; and (cid:129) use and compensation of local employees and suppliers by foreign contractors. Some foreign governments favor or effectively require the awarding of drilling contracts to local contractors, require use of a local agent or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These practices may adversely affect our ability to compete in those regions. It is difficult to predict what governmental regulations may be enacted in the future that could adversely affect the international offshore drilling industry. The actions of foreign governments may materially and adversely affect our ability to compete. In addition, the shipment of goods, including the movement of a drilling rig across international borders, subjects us to extensive trade laws and regulations. Our import activities are governed by unique customs laws and regulations that differ in each of the countries in which we operate and often impose record keeping and reporting obligations. The laws and regulations concerning import/export activity and record keeping and reporting requirements are complex and change frequently. These laws and regulations may be enacted, amended, enforced and/or interpreted in a manner that could materially and adversely impact our operations. Shipments can be delayed and denied export or entry for a variety of reasons, some of which may be outside of our control. Shipping delays or denials could cause unscheduled downtime for our rigs. Failure to comply with these laws and regulations could result in criminal and civil penalties, economic sanctions, seizure of shipments and/or the contractual withholding of monies owed to us, among other things. 9 1 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Compliance with or breach of environmental laws can be costly and could limit our operations. In the United States and in many of the international locations in which we operate, laws and regulations controlling the discharge of materials into the environment, requiring removal and cleanup of materials that may harm the environment or otherwise relating to the protection of the environment apply to some of our operations. For example, we, as an operator of mobile offshore drilling units in navigable United States waters and some offshore areas, may be liable for damages and costs incurred in connection with oil spills related to those operations. Laws and regulations protecting the environment have become increasingly stringent, and may in some cases impose “strict liability,” rendering a person liable for environmental damage without regard to negligence or fault on the part of that person. These laws and regulations may expose us to liability for the conduct of, or conditions caused by, others or for acts that were in compliance with all applicable laws at the time they were performed. U.S. federal and state, foreign and international laws and regulations address oil spill prevention and control and impose a variety of obligations on us related to the prevention of oil spills and liability for damages resulting from such spills. Some of these laws and regulations have significantly expanded liability exposure across all segments of the oil and gas industry. For example, the United States Oil Pollution Act of 1990 imposes strict and, with limited exceptions, joint and several liability upon each responsible party for oil removal costs and a variety of public and private damages. Failure to comply with such laws and regulations could subject us to civil or criminal enforcement action, for which we may not receive contractual indemnification or have insurance coverage, and could result in the issuance of injunctions restricting some or all of our activities in the affected areas. In addition, legislative and regulatory developments may occur following the Macondo well blowout and other events that could substantially increase our exposure to liabilities that might arise in connection with our operations. The application of these laws and regulations or the adoption of new laws and regulations could have a material adverse effect on our financial condition, results of operations and cash flows. We may be subject to litigation and disputes that could have a material adverse effect on us. We are, from time to time, involved in litigation and disputes. These matters may include, among other things, contract disputes, personal injury claims, environmental claims or proceedings, asbestos and other toxic tort claims, employment and tax matters and other litigation that arises in the ordinary course of our business. Although we intend to defend these matters vigorously, we cannot predict with certainty the outcome or effect of any dispute, claim or other litigation matter, and there can be no assurance as to the ultimate outcome of any litigation. We may not have insurance for litigation or claims that may arise, or if we do have insurance coverage it may not be sufficient, insurers may not remain solvent, other claims may exhaust some or all of the insurance available to us or insurers may interpret our insurance policies such that they do not cover losses for which we make claims or may otherwise dispute claims made. Litigation may have a material adverse effect on us because of potential adverse outcomes, defense costs, the diversion of our management’s resources and other factors. We self-insure for physical damage to rigs and equipment caused by named windstorms in the U.S. Gulf of Mexico. Because the amount of insurance coverage available to us is limited, and the cost for such coverage is substantial, we self-insure for physical damage to rigs and equipment caused by named windstorms in the GOM. This results in a higher risk of losses, which could be material, that are not covered by third party insurance contracts. If one or more named windstorms in the GOM cause significant damage to our rigs or equipment, it could have a material adverse effect on our financial condition, results of operations and cash flows. In addition, certain of our shore-based facilities are located in geographic regions that are susceptible to damage or disruption from hurricanes and other weather events. Future hurricanes or similar natural disasters that impact our facilities, our personnel located at those facilities or our ongoing operations may negatively affect our financial position 2 0 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E and operating results for those periods. These negative effects may include reduced or lost sales and revenues; costs associated with interruption in operations and with resuming operations; reduced demand for our services from customers that were similarly affected by these events; lost market share; late deliveries; uninsured property losses; inadequate business interruption insurance; employee evacuations; and an inability to retain necessary staff. We may be required to accrue additional tax liability on certain of our foreign earnings. Certain of our international rigs are owned and operated, directly or indirectly, by Diamond Offshore International Limited, or DOIL, a Cayman Islands subsidiary that we own. It is our intention to indefinitely reinvest future earnings of DOIL and its foreign subsidiaries to finance foreign activities. We do not expect to provide for U.S. taxes on any future earnings generated by DOIL, except to the extent that these earnings are immediately subjected to U.S. federal income tax. Should a future distribution be made from any unremitted earnings of this subsidiary, we may be required to record additional U.S. income taxes that, if material, could have a material adverse effect on our financial condition, results of operations and cash flows. Fluctuations in exchange rates and nonconvertibility of currencies could result in losses to us. Due to our international operations, we have experienced currency exchange losses where revenues are received and expenses are paid in nonconvertible currencies or where we do not effectively hedge an exposure to a foreign currency. We may also incur losses as a result of an inability to collect revenues because of a shortage of convertible currency available to the country of operation, controls over currency exchange or controls over the repatriation of income or capital. We can provide no assurance that financial hedging arrangements will effectively hedge any foreign currency fluctuation losses that may arise. Acts of terrorism and other political and military events could adversely affect the markets for our drilling services. Terrorist attacks and the continued threat of terrorism in the U.S. and abroad, the continuation or escalation of existing armed hostilities or the outbreak of additional hostilities could lead to increased political, economic and financial market instability and a downturn in the economies of the U.S. and other countries. A lower level of economic activity could result in a decline in energy consumption or an increase in the volatility of energy prices, either of which could materially and adversely affect the market for our offshore drilling services, our dayrates or utilization and, accordingly, our financial condition, results of operations and cash flows. While we take steps that we believe are appropriately designed to secure our energy assets, there is no assurance that we can completely secure these assets, completely protect them against a terrorist attack or other political and military events or obtain adequate insurance coverage for such events at reasonable rates. Failure to obtain and retain highly skilled personnel could hurt our operations. We require highly skilled personnel to operate and provide technical services and support for our business. A well- trained, motivated and adequately-staffed work force has a positive impact on our ability to attract and retain business. As a result, our future success depends on our continuing ability to identify, hire, develop, motivate and retain skilled personnel for all areas of our organization. To the extent that demand for drilling services and/or the size of the worldwide industry fleet increases (including due to the impact of newly constructed rigs), shortages of qualified personnel could arise, creating upward pressure on wages and difficulty in staffing and servicing our rigs, which could adversely affect our results of operations. As of the date of this report, we have one new ultra-deepwater drillship and one ultra-deepwater, semisubmersible rig under construction. These rigs are not yet fully crewed as of the date of this report and will require additional skilled personnel to operate. Additional new capacity in the offshore drilling market could also cause further competition for qualified and experienced personnel as these entities seek to hire personnel with expertise in the offshore drilling industry. Our continued ability to compete effectively depends on our ability to attract new employees and to retain and motivate our existing employees. The heightened competition for skilled personnel could 1 2 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I materially and adversely impact our financial condition, results of operations and cash flows by limiting our operations and further increasing our costs. We rely on third-party suppliers, manufacturers and service providers to secure equipment, components and parts used in rig operations, conversions, upgrades and construction. Our reliance on third-party suppliers, manufacturers and service providers to provide equipment and services exposes us to volatility in the quality, price and availability of such items. Certain components, parts and equipment that we use in our operations may be available only from a small number of suppliers, manufacturers or service providers. The failure of one or more third-party suppliers, manufacturers or service providers to provide equipment, components, parts or services, whether due to capacity constraints, production or delivery disruptions, price increases, quality control issues, recalls or other decreased availability of parts and equipment, is beyond our control and could materially disrupt our operations or result in the delay, renegotiation or cancellation of drilling contracts, thereby causing a loss of contract drilling backlog and/or revenue to us, as well as an increase in operating costs. Additionally, our suppliers, manufacturers and service providers could be negatively impacted by current industry conditions or global economic conditions. If certain of our suppliers, manufacturers or service providers were to experience significant cash flow issues, become insolvent or otherwise curtail or discontinue their business as a result of such conditions, it could result in a reduction or interruption in supplies or equipment available to us and/or a significant increase in the price of such supplies and equipment, which could adversely impact our results of operations and cash flows. Our debt levels may limit our liquidity and flexibility in obtaining additional financing and in pursuing other business opportunities. As of December 31, 2014, we had approximately $2.3 billion in senior debt maturing at various times from July 2015 through 2043. We also had $1.5 billion of availability under our revolving credit facility as of that date. We may incur additional indebtedness in the future, including indebtedness under our commercial paper program, and we may borrow from time to time under our revolving credit facility to fund working capital or other needs, subject to compliance with its covenants. Our ability to meet our debt service obligations is dependent upon our future performance, which is subject to general economic conditions, industry cycles and financial, business and other factors affecting our operations, many of which are beyond our control. High levels of indebtedness could have negative consequences to us, including: (cid:129) we may have difficulty satisfying our obligations with respect to our outstanding debt; (cid:129) we may have difficulty obtaining financing in the future for working capital, capital expenditures, acquisitions or other purposes; (cid:129) we may need to use a substantial portion of our available cash flow from operations to pay interest and principal on our debt, which would reduce the amount of money available to fund working capital requirements, capital expenditures, the payment of dividends and other general corporate or business activities; (cid:129) our vulnerability to general economic downturns and adverse industry conditions could increase; (cid:129) our flexibility in planning for, or reacting to, changes in our business and in our industry in general could be limited; (cid:129) our amount of debt and the amount we must pay to service our debt obligations could place us at a competitive disadvantage compared to our competitors that have less debt; 2 2 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E (cid:129) our customers may react adversely to our significant debt level and seek alternative service providers; and (cid:129) our failure to comply with the restrictive covenants in our debt instruments that, among other things, require us to maintain a specified ratio of our consolidated indebtedness to total capitalization and limit the ability of our subsidiaries to incur debt, could result in an event of default that, if not cured or waived, could have a material adverse effect on our business or prospects. In addition, approximately $750.0 million of our long-term debt will mature over the next five years and will need to be paid or refinanced. We may not be able to refinance our maturing debt upon commercially reasonable terms, or at all, depending on numerous factors, including our financial condition and prospects at the time and the then current state of the bank and capital markets in the U.S. Further, our liquidity may be adversely affected if we are unable to replace our revolving credit facility upon acceptable terms when it matures. Our overall debt level and/or market conditions could lead credit rating agencies to lower our long-term and/or short-term corporate credit ratings. In the third quarter of 2014, Standard & Poor’s Ratings Services, or S&P, revised its outlook on us to negative and, in December 2014, S&P lowered our long-term corporate credit and unsecured debt rating from A to A-. Downgrades in our corporate credit ratings could impact our ability to issue additional debt by raising the cost of issuing new debt. As a consequence, we may not be able to issue additional debt in amounts and/or with terms that we consider to be reasonable. One or more of these occurrences could limit our ability to pursue other business opportunities. We may also issue commercial paper to meet our short-term liquidity needs. Our credit ratings are important to our ability to issue commercial paper at favorable rates of interest. A downgrade in our credit rating could increase the cost of borrowing or make the commercial paper market unavailable to us, which could increase our cost of capital. In addition, our access to funds under our commercial paper program is dependent on investor demand for our commercial paper. Disruptions and volatility in the global credit markets could limit the demand for our commercial paper or result in the need to offer higher interest rates to investors, which would result in increased expense and could adversely impact our liquidity. Our revolving credit facility bears interest at variable rates. If market interest rates increase, debt service requirements on amounts outstanding under our revolving credit facility will increase. This would have an adverse effect on our results of operations and cash flows. Although we may employ hedging strategies such that a portion of the aggregate principal amount outstanding under this credit facility carries a fixed rate of interest, any hedging arrangement put in place may not offer complete protection from this risk. Any significant cyber attack or other interruption in network security or the operation of critical computer systems could materially disrupt our operations and adversely affect our business. Our business has become increasingly dependent upon information technologies, systems and networks to conduct day-to-day operations, and we are placing greater reliance on technology to help support our operations and increase efficiency in our business functions. We are dependent upon our information technology and infrastructure, including operational and financial computer systems to process the data necessary to conduct almost all aspects of our business. Computer and other business facilities and systems could become unavailable or impaired from a variety of causes including, among others, storms and other natural disasters, terrorist attacks, utility outages, theft, design defects, human error or complications encountered as existing systems are maintained, repaired, replaced or upgraded. It has also been reported that unknown entities or groups have mounted so-called “cyber attacks” on businesses and other organizations solely to disable or disrupt computer systems, disrupt operations and, in some cases, steal data. A breach or failure of our computer systems or networks, or those of our customers, vendors or others with whom we do business, could materially disrupt our business operations and could result in the alteration, loss, theft or corruption of data or unauthorized release of confidential, proprietary or sensitive data concerning our company, business activities, employees, customers or vendors. Any such breach or failure could have a material adverse effect on our operations, business or reputation. 3 2 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Unionization efforts and labor regulations in some of the countries in which we operate could materially increase our costs or limit our flexibility. Some of our employees in non-U.S. markets are represented by labor unions and work under collective bargaining or similar agreements which are subject to periodic renegotiation. These negotiations could result in higher personnel expenses, other increased costs or increased operational restrictions. Efforts have been made from time to time to unionize other portions of our workforce. In addition, we may be subjected to strikes or work stoppages and other labor disruptions in certain countries. Additional unionization efforts, new collective bargaining agreements or work stoppages could materially increase our costs, reduce our revenues or limit our flexibility. We are controlled by a single stockholder, which could result in potential conflicts of interest. Loews Corporation, which we refer to as Loews, beneficially owned approximately 52.5% of our outstanding shares of common stock as of February 16, 2015, and is in a position to control actions that require the consent of stockholders, including the election of directors, amendment of our Restated Certificate of Incorporation and any merger or sale of substantially all of our assets. In addition, three officers of Loews serve on our Board of Directors. One of those, James S. Tisch, the Chairman of the Board of our company, is also the Chief Executive Officer and a director of Loews. We have also entered into a services agreement and a registration rights agreement with Loews, and we may in the future enter into other agreements with Loews. Loews is a holding company. In addition to us, its principal subsidiaries are CNA Financial Corporation, a 90% owned subsidiary engaged in commercial property and casualty insurance; Boardwalk Pipeline Partners, LP, a 53% owned subsidiary engaged in transportation and storage of natural gas and natural gas liquids and gathering and processing of natural gas; and Loews Hotels Holding Corporation, a wholly-owned subsidiary engaged in the operation of a chain of hotels. It is possible that Loews may in some circumstances be in direct or indirect competition with us, including competition with respect to certain business strategies and transactions that we may propose to undertake. In addition, potential conflicts of interest exist or could arise in the future for our directors who are also officers of Loews with respect to a number of areas relating to the past and ongoing relationships of Loews and us, including tax and insurance matters, financial commitments and sales of common stock pursuant to registration rights or otherwise. Although the affected directors may abstain from voting on matters in which our interests and those of Loews are in conflict so as to avoid potential violations of their fiduciary duties to stockholders, the presence of potential or actual conflicts could affect the process or outcome of Board deliberations. We cannot assure you that these conflicts of interest will not materially adversely affect us. Item 1B. Unresolved Staff Comments. Not applicable. Item 2. Properties. We own an office building in Houston, Texas, where our corporate headquarters are located. We also own offices and other facilities in New Iberia, Louisiana, Aberdeen, Scotland, Macae, Brazil and Ciudad del Carmen, Mexico.

This number represents registered stockholders and does not include stockholders who hold their shares institutionally. Dividend Policy In 2014, we paid regular cash dividends of $0.125 and special cash dividends of $0.75 per share of our common stock on March 3, June 2, September 2 and December 1. In 2013, we paid regular cash dividends of $0.125 and special cash dividends of $0.75 per share of our common stock on March 1, June 3, September 3 and December 2. On February 6, 2015, we declared a regular cash dividend of $0.125 per share of our common stock payable on March 2, 2015 to stockholders of record on February 20, 2015. Our Board of Directors has adopted a policy of considering paying regular and special cash dividends, in amounts to be determined, on a quarterly basis. Any determination to declare a regular or special dividend, as well as the amount of any dividend that may be declared, will be based on the Board’s consideration of our financial position, earnings, earnings outlook, capital spending plans, outlook on current and future market conditions and other factors that our Board of Directors considers relevant at that time. Our dividend policy may change from time to time, and there can be no assurance that we will continue to declare any regular or special cash dividends at all or in any particular amounts. See “Risk Factors – Although we have paid cash dividends in the past, we will not pay a special dividend in the first quarter of 2015, we may not pay regular or special cash dividends in the future and we can give no assurance as to the amount or timing of the payment of any future regular or special cash dividends” in Item 1A of this report, which is incorporated herein by reference. 5 2 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I CUMULATIVE TOTAL STOCKHOLDER RETURN The following graph shows the cumulative total stockholder return for our common stock, the Standard & Poor’s 500 Index and the Dow Jones U.S. Oil Equipment & Services index over the five year period ended December 31, 2014.

(4) For all periods presented, the ratio of earnings to fixed charges has been computed on a total enterprise basis. Earnings represent pre-tax income from continuing operations plus fixed charges. Fixed charges include (i) interest, whether expensed or capitalized, (ii) amortization of debt issuance costs, whether expensed or capitalized, and (iii) a portion of rent expense, which we believe represents the interest factor attributable to rent. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. The following discussion should be read in conjunction with our Consolidated Financial Statements (including the Notes thereto) in Item 8 of this report. We are a leader in offshore drilling, providing contract drilling services to the energy industry around the globe with a fleet of 38 offshore drilling rigs, excluding three mid-water semisubmersible rigs that we plan to retire and scrap. In late 2014, we took delivery of two ultra-deepwater drillships, the Ocean BlackHornet and Ocean BlackRhino. Contract preparation work is underway for both rigs, which are expected to commence drilling operations in the GOM in the second quarter of 2015. Construction of the Ocean Apex was completed late in the fourth quarter of 2014, and the rig is currently operating under a one-well contract in Vietnam. During the first quarter of 2015, we expect to take delivery of our remaining ultra-deepwater drillship Ocean BlackLion and to complete the service-life-extension project for the ultra-deepwater Ocean Confidence. We expect the harsh environment, ultra-deepwater semisubmersible Ocean GreatWhite to be delivered in the first quarter of 2016. 7 2 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Market Overview Market fundamentals in the oil and gas industry continued to deteriorate in the fourth quarter of 2014 and into 2015. The dramatic decline in oil prices since the summer of 2014 has led many of our customers or potential customers to announce significant cutbacks to their 2015 capital spending plans. These adverse market conditions have resulted in reduced demand for offshore drilling rigs by our customers and an oversupply of rigs available for charter. Based on these factors, industry analysts predict dayrates to decline further as competition to keep rigs active continues to intensify. As of February 9, 2015, eight of our rigs were not subject to a drilling contract with a customer, including six rigs that have been cold stacked or are in the process of being cold stacked. In declining markets, rig tenders by our customers may be for shorter terms or on a well-to-well basis and increased competition for the tenders may drive down contract dayrates. It is also not unusual for adverse market conditions to result in the migration of some ultra-deepwater rigs to work in deepwater and, likewise, some deepwater rigs to compete against mid-water units, or even ultra-deepwater rigs to work in some mid-water markets. This has had and could continue to have an adverse impact on our fleet, and particularly our lower specification mid-water rigs, as indicated by the retirement of six of our mid-water semisubmersible rigs during 2014, three of which have since been scrapped as of the date of this report. Another characteristic of the depressed market conditions in the offshore drilling industry is that certain customers may attempt to renegotiate or terminate drilling contracts. Some of our drilling contracts, particularly contracts with national oil companies or government-controlled entities, permit the customer to terminate the contract after specified notice periods, sometimes resulting in no payment to us or sometimes resulting in a contractually specified termination amount, which may not fully compensate us for the loss of the contract. During depressed market conditions, certain customers may be more motivated to utilize such contract clauses to seek to renegotiate or terminate a drilling contract. In addition, in depressed conditions certain customers may be motivated to claim that we have breached provisions of our drilling contracts in order to avoid their obligations to us under circumstances where we believe we are in compliance with the contracts. The early termination of a contract may result in a rig being idle for an extended period of time, which could adversely affect our financial condition, results of operations and cash flows. When a customer terminates our contract prior to the contract’s scheduled expiration, our contract backlog is adversely impacted. See “— Contract Drilling Backlog” below. On February 20, 2015, a representative of PEMEX — Exploracio´n y Produccio´n, or PEMEX, verbally informed us of PEMEX’s intention to exercise its contractual right to terminate its drilling contracts on the Ocean Ambassador, the Ocean Nugget and the Ocean Summit, and to cancel its drilling contract on the Ocean Lexington, which contract was scheduled to begin in September 2015. As of the date of this report, we have not received written notice of termination or cancellation. We are in discussions with PEMEX regarding the rigs. 2 8 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E In addition, Petro´leo Brasileiro S.A., or Petrobras, recently notified us that it has a right to terminate the drilling contract on the Ocean Baroness and has verbally informed us that it does not intend to continue to use the rig. We are currently in discussions with Petrobras regarding the rig. The impact of the depressed market conditions in the offshore drilling industry has materially impacted our results of operations and cash flows in 2014. We currently expect that these adverse conditions will continue through 2015 and likely into 2016 or even longer. The continuation of these conditions could result in more of our rigs being without contracts and/or cold stacked and could further materially and adversely affect our financial condition, results of operations and cash flows. When we cold stack a rig, we evaluate the rig for impairment. See “Risk Factors — We may incur asset impairments and/or rig retirements as a result of declining demand for certain offshore drilling rigs” in Item 1A of this report, which is incorporated herein by reference. Although these general market conditions impact all segments of the offshore drilling market, the following discussion addresses market conditions within segments of the floater market. Floater Markets Ultra-Deepwater and Deepwater Floaters. Globally, the ultra-deepwater and deepwater floater markets continue to weaken. The continuing oversupply of rigs, combined with diminished demand, has resulted in further decline in dayrates and the stacking of rigs in all asset classes, and industry reports expect offshore drillers to continue to scrap older, lower specification rigs. During 2014, there were few bidding opportunities, and the outlook for 2015 is pessimistic. Competition for a limited number of jobs has been intense, with numerous offshore drillers vying for the same opportunities, including some competitors bidding multiple rigs on the same bid, and operators attempting to sublet previously contracted rigs for which capital spending programs have been delayed and/or canceled. The influx of newbuilds into the market, combined with established rigs that came off contract in 2014 or are expected to complete contracts during 2015 and 2016, is expected to contribute to the further weakening of the ultra- deepwater and deepwater floater markets. As of the date of this report, based on industry data, there are approximately 59 competitive, or non-owner-operated, newbuild floaters on order, and an estimated 29 additional rigs potentially to be built on behalf of Petrobras, which is currently our largest single customer based on annual consolidated revenues. Based on industry reports, of the competitive rigs, 16 of the 31 newbuilds scheduled for delivery in 2015, as well as nine of the 14 newbuilds scheduled for delivery in 2016, are not yet contracted for future work. Mid-Water Floaters. Conditions in the mid-water market have varied by region, but have generally been adversely impacted by lower demand, the waterfall effect of declining dayrates in the ultra-deepwater and deepwater markets, the challenges experienced by lower specification units in this segment as a result of growing regulatory demands and more complex customer specifications, and the intensified competition resulting from the migration of some deepwater and ultra-deepwater units to compete against mid-water units. As higher specification rigs take the place of lower specification units, some lower specification rigs are expected to be cold stacked or ultimately scrapped. See “— Contract Drilling Backlog” for future commitments of our rigs during 2015 through 2020. Contract Drilling Backlog The following table reflects our contract drilling backlog as of February 9, 2015, October 21, 2014 (the date reported in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2014), and February 5, 2014 (the date reported in our Annual Report on Form 10-K for the year ended December 31, 2013). Contract drilling backlog as presented below includes only firm commitments (typically represented by signed contracts) and is calculated by multiplying the contracted operating dayrate by the firm contract period and adding one-half of any potential rig performance bonuses. Our calculation also assumes full utilization of our drilling equipment for the contract period (excluding scheduled shipyard and survey days); however, the amount of actual revenue earned and the actual periods during which revenues 9 2 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I are earned will be different than the amounts and periods shown in the tables below due to various factors. Utilization rates, which generally approach 92-98% during contracted periods, can be adversely impacted by downtime due to various operating factors including, but not limited to, weather conditions and unscheduled repairs and maintenance. Contract drilling backlog excludes revenues for mobilization, demobilization, contract preparation and customer reimbursables. No revenue is generally earned during periods of downtime for regulatory surveys. Changes in our contract drilling backlog between periods are generally a function of the performance of work on term contracts, as well as the extension or modification of existing term contracts and the execution of additional contracts. In addition, under certain circumstances, our customers may seek to terminate or renegotiate our contracts. See “Risk Factors — We can provide no assurance that our drilling contracts will not be terminated early or that our current backlog of contract drilling revenue will be ultimately realized” in Item 1A of this report, which is incorporated herein by reference.

(2) Contract drilling backlog as of February 9, 2015 for our ultra-deepwater floaters excludes $408.4 million attributable to the Ocean Baroness contracted to Petrobras. See discussion under “Market Overview” above. (3) Contract drilling backlog as of February 9, 2015 for our deepwater floaters includes $196.0 million attributable to our contracted operations offshore Brazil for the years 2015 to 2016. (4) Contract drilling backlog reported as of October 21, 2014 for our mid-water floaters excludes $107.0 million in backlog attributable to contracted work for the Ocean Vanguard that is included in the February 5, 2014 backlog. As previously reported, in the second quarter of 2014, Statoil ASA, the customer for the Ocean Vanguard, terminated its drilling contract, which was estimated to conclude in accordance with its terms in February 2015. We do not believe that Statoil had a valid basis for terminating the contract, and we have filed a lawsuit against Statoil in Norway to collect damages resulting from the unlawful termination. (5) Contract drilling backlog as of February 9, 2015 for our mid-water floaters (i) includes $21.0 million attributable to our contracted operations offshore Brazil for the year 2015 and (ii) excludes $52.8 million from 2015 that was originally attributable to contracted work for the Ocean Nomad and previously reported as backlog for 2015. On February 12, 2015, our subsidiary received notice of termination of its drilling contract from Dana Petroleum (E&P) Limited, the customer for the Ocean Nomad. The drilling contract provides for a dayrate of approximately $330,000 and was estimated to conclude in accordance with its terms in August 2015. We do not believe that Dana had a valid basis for terminating the contract and we intend to defend our rights under the contract. (6) Contract drilling backlog as of February 9, 2015 for our mid-water floaters excludes $208.8 million attributable to the Ocean Ambassador and the Ocean Lexington. See discussion under “Market Overview” above. (7) Contract drilling backlog as of February 9, 2015 for our jack-ups excludes $49.0 million attributable to the Ocean Nugget and the Ocean Summit.

(5) Contract drilling backlog as of February 9, 2015 for our mid-water floaters (i) includes $21.0 million for the year 2015 attributable to our contracted operations offshore Brazil and (ii) excludes $52.8 million for the year 2015 that was originally attributable to contracted work for the Ocean Nomad and previously reported as backlog for 2015. On February 12, 2015, our subsidiary received notice of termination of its drilling contract from Dana Petroleum (E&P) Limited, the customer for the Ocean Nomad. The drilling contract provides for a dayrate of approximately $330,000 and was estimated to conclude in accordance with its terms in August 2015. We do not believe that Dana had a valid basis for terminating the contract, and we intend to defend our rights under the contract. (6) Contract drilling backlog as of February 9, 2015 for our mid-water floaters excludes $69.6 million, $66.6 million, $58.4 million, and $14.2 million for the years 2015, 2016, 2017 and 2018, respectively, attributable to the Ocean Ambassador and the Ocean Lexington. See discussion under “Market Overview” above. (7) Contract drilling backlog as of February 9, 2015 for our jack-ups excludes $26.9 million and $22.1 million for the years 2015 and 2016, respectively, attributable to the Ocean Nugget and the Ocean Summit.

The percentage of rig days committed is calculated as the ratio of total days committed under contracts, as well as scheduled shipyard, survey and mobilization days for all rigs in our fleet, to total available days (number of rigs multiplied by the number of days in a particular year). Total available days have been calculated based on the expected final commissioning dates for the Ocean BlackLion and Ocean GreatWhite, both of which are under construction.

See discussion under “Market Overview” above. Important Factors That May Impact Our Operating Results, Financial Condition or Cash Flows Operating Income. Our operating income is primarily a function of contract drilling revenue earned less contract drilling expenses incurred or recognized. The two most significant variables affecting our contract drilling revenue are the dayrates earned and utilization rates achieved by our rigs, each of which is a function of rig supply and demand in the marketplace. These factors are not within our control and are difficult to predict. We generally recognize revenue from dayrate drilling contracts as services are performed. Consequently, when a rig is idle, no dayrate is earned and revenue will decrease as a result. Revenue is also affected by the acquisition or disposal of rigs, rig mobilizations, required surveys and shipyard projects. In connection with certain drilling contracts, we may receive fees for the mobilization of equipment. In addition, some of our drilling contracts require downtime before the start of the contract to prepare the rig to meet customer requirements for which we may or may not be compensated. We earn these fees as services are performed over the initial term of the related drilling contracts. We defer mobilization and contract preparation fees received (on either a lump-sum or dayrate basis), as well as direct and incremental costs associated with the mobilization of equipment and contract preparation activities, and amortize each, on a straight-line basis, over the term of the related drilling contracts. Absent a contract, mobilization costs are recognized currently. Operating income also fluctuates due to varying levels of contract drilling expenses. Our operating expenses represent all direct and indirect costs associated with the operation and maintenance of our drilling equipment, which generally are not affected by changes in dayrates and short-term reductions in utilization. For instance, if a rig is to be idle for a short period of time, few decreases in operating expenses may actually occur since the rig is typically maintained in a prepared or “warm stacked” state with a full crew. In addition, when a rig is idle, we are responsible for certain operating expenses such as rig fuel and supply boat costs, which are typically costs of the operator when a rig is under contract. However, if a rig is expected to be idle for an extended period of time, we may reduce the size of a rig’s crew and take steps to “cold stack” the rig, which lowers expenses and partially offsets the impact on operating income. 3 2 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E The principal components of our operating costs are, among other things, direct and indirect costs of labor and benefits, repairs and maintenance, freight, regulatory inspections, boat and helicopter rentals and insurance. Labor and repair and maintenance costs represent the most significant components of our operating expenses. In general, our labor costs increase primarily due to higher salary levels, rig staffing requirements and costs associated with labor regulations in the geographic regions in which our rigs operate. In addition, the costs associated with training new and seasoned employees can be significant. Costs to repair and maintain our equipment fluctuate depending upon the type of activity the drilling unit is performing, as well as the age and condition of the equipment and the regions in which our rigs are working. Regulatory Surveys and Planned Downtime. Our operating income is negatively impacted when we perform certain regulatory inspections, which we refer to as a 5-year survey, or special survey, that are due every five years for each of our rigs. Operating revenue decreases because these special surveys are generally performed during scheduled downtime in a shipyard. Operating expenses increase as a result of these special surveys due to the cost to mobilize the rigs to a shipyard, inspection costs incurred and repair and maintenance costs, which are recognized as incurred. Repair and maintenance activities may result from the special survey or may have been previously planned to take place during this mandatory downtime. The number of rigs undergoing a 5-year survey will vary from year to year, as well as from quarter to quarter. In addition, operating income may also be negatively impacted by intermediate surveys, which are performed at interim periods between 5-year surveys. Intermediate surveys are generally less extensive in duration and scope than a 5- year survey. Although an intermediate survey may require some downtime for the drilling rig, it normally does not require dry-docking or shipyard time, except for rigs generally older than 15 years that are located in the U.K. and Norwegian sectors of the North Sea. During 2015, two of our rigs will require 5-year surveys, which we expect to result in approximately 120 days of downtime in the aggregate. We also expect to spend an additional approximately 980 days for intermediate surveys, the mobilization of rigs, contract acceptance testing and extended maintenance projects, including days associated with mobilization and acceptance testing for the recently delivered Ocean BlackHornet and Ocean BlackRhino (approximately 195 days in the aggregate) and the Ocean BlackLion (approximately 240 days), which is under construction and expected to be delivered late in the first quarter of 2015. We expect the Ocean Confidence to be unavailable through the first quarter of 2015 (approximately 90 days) as it completes its service-life-extension project. We can provide no assurance as to the exact timing and/or duration of downtime associated with regulatory inspections, planned rig mobilizations and other shipyard projects. See “— Contract Drilling Backlog.” Physical Damage and Marine Liability Insurance. We are self-insured for physical damage to rigs and equipment caused by named windstorms in the GOM. If a named windstorm in the GOM causes significant damage to our rigs or equipment, it could have a material adverse effect on our financial condition, results of operations and cash flows. Under our insurance policy that expires on May 1, 2015, we carry physical damage insurance for certain losses other than those caused by named windstorms in the GOM for which our deductible for physical damage is $25.0 million per occurrence. We do not typically retain loss-of-hire insurance policies to cover our rigs. In addition, under our current insurance policy, we carry marine liability insurance covering certain legal liabilities, including coverage for certain personal injury claims, and generally covering liabilities arising out of or relating to pollution and/or environmental risk. We believe that the policy limit for our marine liability insurance is within the range that is customary for companies of our size in the offshore drilling industry and is appropriate for our business. Our deductibles for marine liability coverage, including for personal injury claims, are $25.0 million for the first occurrence and vary in amounts ranging between $5.0 million and, if aggregate claims exceed certain thresholds, up to $100.0 million for each subsequent occurrence, depending on the nature, severity and frequency of claims that might arise during the policy year. Construction and Capital Upgrade Projects. We capitalize interest cost for the construction and upgrade of qualifying assets in accordance with accounting principles generally accepted in the U.S., or GAAP. The period of interest capitalization covers the duration of the activities required to make the asset ready for its intended use, and the capitalization period ends when the asset is substantially complete and ready for its intended use, which is expected to continue after delivery of the rigs from the shipyard and until the user acceptance phase of each project is completed. For the year ended December 31, 2014, we capitalized interest of $60.6 million on qualifying expenditures, primarily related to the construction of our four new drillships, the Ocean GreatWhite and the Ocean Apex. We will continue capitalizing interest on qualifying expenditures during 2015, which will no longer include expenditures related to the Ocean BlackHawk, Ocean BlackHornet, Ocean BlackRhino and Ocean Onyx, which were completed in 2014, and will include a limited interest capitalization period for the Ocean BlackLion, which is expected to be completed in the first quarter of 2015. Impact of Changes in Tax Laws or Their Interpretation. We operate through our various subsidiaries in a number of countries throughout the world. As a result, we are subject to highly complex tax laws, treaties and regulations in the jurisdictions in which we operate, which may change and are subject to interpretation. Changes in laws, treaties and regulations and the interpretation of such laws, treaties and regulations may put us at risk for future tax assessments and liabilities which could be substantial and could have a material adverse effect on our financial condition, results of 3 3 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I operations and cash flows. Critical Accounting Estimates Our significant accounting policies are included in Note 1 “General Information” to our Consolidated Financial Statements in Item 8 of this report. Judgments, assumptions and estimates by our management are inherent in the preparation of our financial statements and the application of our significant accounting policies. We believe that our most critical accounting estimates are as follows: Property, Plant and Equipment. We carry our drilling and other property and equipment at cost. Maintenance and routine repairs are charged to income currently while replacements and betterments, including associated inspection and recertification costs, which upgrade or increase the functionality of our existing equipment and that significantly extend the useful life of an existing asset, are capitalized. Significant judgments, assumptions and estimates may be required in determining whether or not such replacements and betterments meet the criteria for capitalization and in determining useful lives and salvage values of such assets. Changes in these judgments, assumptions and estimates could produce results that differ from those reported. Historically, the amount of capital additions requiring significant judgments, assumptions or estimates has not been significant. During the years ended December 31, 2014 and 2013, we capitalized $546.0 million and $302.0 million, respectively, in replacements and betterments of our drilling fleet, resulting from numerous projects ranging from $25,000 to $160 million per project. We evaluate our property and equipment for impairment whenever changes in circumstances indicate that the carrying amount of an asset may not be recoverable (such as cold stacking a rig, the expectation of cold stacking a rig in the near term, a decision to retire or scrap a rig, or excess spending over budget on a newbuild, construction project or major rig upgrade). We utilize an undiscounted probability-weighted cash flow analysis in testing an asset for potential impairment. Our assumptions and estimates underlying this analysis include the following: (cid:129) dayrate by rig; (cid:129) utilization rate by rig (expressed as the actual percentage of time per year that the rig would be used); (cid:129) the per day operating cost for each rig if active, warm stacked or cold stacked; (cid:129) the estimated annual cost for rig replacements and/or enhancement programs; (cid:129) the estimated maintenance, inspection or other costs associated with a rig returning to work; (cid:129) salvage value for each rig; and 3 4 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E (cid:129) estimated proceeds that may be received on disposition of the rig. Based on these assumptions and estimates, we develop a matrix using several different utilization/dayrate scenarios, to each of which we have assigned a probability of occurrence. The sum of our utilization scenarios (which include active, warm stacked and cold stacked) and probability of occurrence scenarios both equal 100% in the aggregate. We reevaluate these rigs annually, by updating the matrices for each rig and modifying our assumptions, giving consideration to the length of time the rig has been cold stacked, the current and expected market for the type of rig and expectations of future oil and gas prices. In the third quarter of 2014, we recognized an impairment loss of $109.5 million in connection with our management’s decision to retire and scrap six mid-water semisubmersible rigs, or the Retirement Group, which included three rigs that were initially impaired in 2012. Of the Retirement Group, two of the rigs were scrapped in December 2014, and one additional rig was scrapped in February 2015. We have entered into a sales agreement to scrap a fourth rig in the Retirement Group, which we expect to close in the first quarter of 2015. We did not recognize an asset impairment in 2013. During 2012, we recognized an impairment loss of $62.4 million. See “— Results of Operations — Years Ended December 31, 2014, 2013 and 2012 — Overview — 2014 Compared to 2013 — Impairment of Assets,” “— Results of Operations — Years Ended December 31, 2014, 2013 and 2012 — Overview — 2013 Compared to 2012 — Impairment of Assets” and Note 2 “Asset Impairments” to our Consolidated Financial Statements in Item 8 of this report. Management’s assumptions are an inherent part of our asset impairment evaluation and the use of different assumptions could produce results that differ from those reported. Personal Injury Claims. Our deductibles for liability coverage for personal injury claims, which primarily result from Jones Act liability in the Gulf of Mexico, are currently $25.0 million for the first occurrence, with no aggregate deductible, and vary in amounts ranging between $5.0 million and, if aggregate claims exceed certain thresholds, up to $100.0 million for each subsequent occurrence, depending on the nature, severity and frequency of claims which might arise during the policy year. The Jones Act is a federal law that permits seamen to seek compensation for certain injuries during the course of their employment on a vessel and governs the liability of vessel operators and marine employers for the work-related injury or death of an employee. We engage outside consultants to assist us in estimating our aggregate liability for personal injury claims based on our historical losses and utilizing various actuarial models. The models used in estimating our aggregate reserve for personal injury claims include actuarial assumptions such as: (cid:129) claim emergence, or the delay between occurrence and recording of claims; (cid:129) settlement patterns, or the rates at which claims are closed; (cid:129) development patterns, or the rate at which known cases develop to their ultimate level; (cid:129) average, potential frequency and severity of claims; and (cid:129) effect of re-opened claims. The eventual settlement or adjudication of these claims could differ materially from our estimated amounts due to uncertainties such as: (cid:129) the severity of personal injuries claimed; (cid:129) significant changes in the volume of personal injury claims; (cid:129) the unpredictability of legal jurisdictions where the claims will ultimately be litigated; 5 3 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I (cid:129) inconsistent court decisions; and (cid:129) the risks and lack of predictability inherent in personal injury litigation. Income Taxes. We account for income taxes in accordance with accounting standards that require the recognition of the amount of taxes payable or refundable for the current year and an asset and liability approach in recognizing the amount of deferred tax liabilities and assets for the future tax consequences of events that have been currently recognized in our financial statements or tax returns. In each of our tax jurisdictions we recognize a current tax liability or asset for the estimated taxes payable or refundable on tax returns for the current year and a deferred tax asset or liability for the estimated future tax effects attributable to temporary differences and carryforwards. Deferred tax assets are reduced by a valuation allowance, if necessary, which is determined by the amount of any tax benefits that, based on available evidence, are not expected to be realized under a “more likely than not” approach. We do not establish deferred tax liabilities for certain of our foreign earnings that we intend to indefinitely reinvest to finance foreign activities. However, if these earnings become subject to U.S. federal tax, any required provision could have a material adverse impact on our financial results. We make judgments regarding future events and related estimates especially as they pertain to the forecasting of our effective tax rate, the potential realization of deferred tax assets such as utilization of foreign tax credits, and exposure to the disallowance of items deducted on tax returns upon audit. Certain of our international rigs are owned and operated, directly or indirectly, by Diamond Offshore International Limited, or DOIL, a Cayman Islands subsidiary which we wholly own. It is our intention to indefinitely reinvest future earnings of DOIL and its foreign subsidiaries to finance foreign activities. Accordingly, we have not made a provision for U.S. income taxes on approximately $2.4 billion of undistributed foreign earnings and profits. Although we do not intend to repatriate the earnings of DOIL and have not provided U.S. income taxes for such earnings, except to the extent that such earnings were immediately subject to U.S. income taxes, these earnings could become subject to U.S. income tax if remitted, or if deemed remitted as a dividend; however, it is not practicable to estimate this potential liability. In several of the international locations in which we operate, certain of our wholly-owned subsidiaries enter into agreements with other of our wholly-owned subsidiaries to provide specialized services and equipment in support of our foreign operations. We apply a transfer pricing methodology to determine the amount to be charged for providing the services and equipment, and utilize outside consultants to assist us in the development of such transfer pricing methodologies. In most cases, there are alternative transfer pricing methodologies that could be applied to these transactions and, if applied, could result in different chargeable amounts. Results of Operations Although we perform contract drilling services with different types of drilling rigs and in many geographic locations, there is a similarity of economic characteristics due to the nature of the revenue earning process as it relates to the offshore drilling industry, over the operating lives of our drilling rigs. We believe that the combination of our drilling rigs into one reportable segment is the appropriate aggregation in accordance with applicable accounting standards on segment reporting. However, for purposes of this discussion and analysis of our results of operations, we provide greater detail with respect to the types of rigs in our fleet to enhance the reader’s understanding of our financial condition, changes in financial condition and results of operations. 3 6 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E Key performance indicators by equipment type are listed below.

Operating income decreased $229.0 million, or 29%, during 2014, compared to 2013, primarily due to a $106.5 million, or 4%, reduction in contract drilling revenue combined with the negative effects of a $109.5 million impairment loss recognized in the third quarter of 2014, higher depreciation ($68.4 million) and higher general and administrative expenses ($17.0 million). During 2014, we recognized incremental depreciation expense on a higher depreciable asset base, compared to 2013, which included the following newly constructed rigs placed in service during 2014: Ocean Onyx (January 2014), Ocean BlackHawk (February 2014) and Ocean BlackHornet, Ocean BlackRhino and Ocean Apex (December 2014). General and administrative costs for 2014 reflect higher employee compensation and professional fees than those incurred in the prior year, primarily related to compensation of and termination benefits paid to certain of our current and former key executives. These negative effects were partially offset by a $48.9 million reduction in contract drilling expense and a $22.5 million charge for an uncollectible receivable incurred in the prior year. Contract drilling revenue for our deepwater and mid-water fleets decreased $122.8 million and $121.1 million, respectively, during 2014, compared to the prior year, primarily as a result of 324 and 217 fewer revenue earning days, respectively, combined with the effect of a lower average daily revenue earned by our mid-water floater fleet in the aggregate. In contrast, contract drilling revenue earned by our ultra-deepwater floaters and jack-up rigs increased $133.1 million and $4.4 million, respectively, during 2014, compared to 2013, primarily due to higher average daily revenue earned by both our ultra-deepwater and jack-up fleets despite an aggregate 345-day reduction in revenue earning days during 2014. In general, the comparability of contract drilling expenses between years is impacted by significant events or changes in our rig fleet, including but not limited to the relocation of rigs between geographic locations and related changes in operating cost structures which differ between regions, the cost to mobilize such rigs, the number and extent of shipyard surveys and related repairs, contract preparation activities, the stacking of rigs and rising labor costs. Total contract drilling expense for our rig fleet during 2014 decreased by $48.9 million, or 3%, compared to the prior year, primarily due to the cold stacking or scrapping of rigs, contract preparation work and lower repairs and maintenance expenses, partially offset by increases in costs associated with the operation of the Ocean BlackHawk and Ocean Onyx beginning in the first quarter of 2014. Impairment of Assets. During the third quarter of 2014, our management adopted a plan to scrap six of our mid-water semisubmersibles. As a result of this decision, we recognized an impairment loss of $109.5 million to write down the aggregate net book value of these rigs to their estimated recoverable amounts. Three of these rigs were initially impaired in 2012. See “— 2013 Compared to 2012 — Impairments of Assets.” Bad Debt Expense (Recovery). During 2013, based on our assessment of the financial condition of two of our customers, Niko Resources Ltd., or Niko, and OGX Petróleo e Gás Ltda., or OGX, and our expectations regarding the probability of collection of amounts due to us from them, we recorded $22.5 million in bad debt expense to fully reserve all outstanding receivables they owed us at June 30, 2013. Four of our rigs remained under contract to Niko and OGX in the second half of 2013, working an aggregate of 337 revenue earning days for which we did not recognize revenue due to our assessment that collection of the amounts due was not reasonably assured. In December 2013, we entered into a settlement agreement with Niko, which we refer to as the Settlement Agreement, whereby Niko will be released from certain obligations under the dayrate contracts for the Ocean Monarch and Ocean Lexington, subject to and effective upon the full payment of amounts owed to us under the Settlement Agreement, aggregating $80.0 million, and subject to its other conditions. In accordance with the terms of the Settlement Agreement, we received cash payments of $20.3 million during 2014 and $25.0 million in the fourth quarter of 2013, which we recognized as revenue against invoices due us. We plan to recognize future payments from Niko in revenue as they are received due to the uncertainty regarding their timing and collection. 4 0 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E In 2014, the creditors of OGX, including us, agreed to a settlement whereby the creditors would receive shares of the reorganized OGX company in full settlement of obligations owed to them by OGX. As a result of the settlement, we have written off $21.2 million in receivables due us from OGX against the associated allowance for bad debts, which was set up in 2013. No additional provisions for bad debts were deemed necessary in 2014. Interest Expense. Interest expense increased $37.2 million during 2014, compared to 2013, primarily due to incremental interest expense of $34.4 million primarily related to $1.0 billion in senior unsecured notes that we issued in November 2013, partially offset by a reduction in interest expense related to $250.0 million in senior debt that we repaid in 2014, combined with a decrease in capitalized interest of $13.6 million as a result of rig construction projects completed in 2014. The increase in interest expense was also partially offset by the reversal of $6.2 million of interest expense in 2014 associated with changes in uncertain tax positions in the Brazil and Mexico tax jurisdictions, combined with the absence of $5.9 million of interest expense recognized in the prior year period associated with uncertain tax positions in the Mexico tax jurisdiction. Income Tax Expense. Our effective tax rate for 2014 was 24.9%, compared to a 29.1% effective tax rate for 2013. The lower effective tax rate in 2014 was due to differences in the mix of our domestic and international pre-tax earnings and losses, as well as the mix of international tax jurisdictions in which we operated. The lower effective tax rate in the current period was also due to the reversal of $54.5 million of reserves for uncertain tax positions in various foreign jurisdictions which were settled in our favor or for which the statute of limitations had expired. During the 2013 period, our effective tax rate was negatively impacted by a provision of $56.9 million related to an uncertain tax position in Egypt, partially offset by the recognition of the impact of The American Taxpayer Relief Act of 2012, which reduced 2013 income tax expense by $27.5 million. 2013 Compared to 2012 Operating Income. Operating income decreased $160.8 million, or 17%, in 2013, compared to 2012, primarily due to a $92.5 million, or 3%, reduction in contract drilling revenue, a $35.3 million increase in contract drilling expense and recognition of $22.5 million of bad debt expense in 2013, combined with the absence of an aggregate $76.5 million pre-tax gain on the sale of six of our jack-up rigs during 2012. These negative contributors to operating income were partially offset by the absence of a $62.4 million impairment loss recognized in the fourth quarter of 2012. Contract drilling revenue for our ultra-deepwater and mid-water fleets decreased a combined $125.4 million during 2013, compared to 2012, while revenue earned by our deepwater floaters and jack-up rigs increased an aggregate $32.9 million. Revenue earning days for our drilling fleet decreased an aggregate 415 days in 2013, compared to 2012, including 337 fewer revenue earning days for the Ocean Monarch, Ocean Star, Ocean Lexington and Ocean Quest in the second half of 2013, during which these rigs were contracted to Niko or OGX, and 87 fewer days attributable to the jack-up rigs that we sold in 2012. Total contract drilling expense for our rig fleet during 2013 increased by $35.3 million, compared to 2012, reflecting higher labor and personnel-related costs ($38.1 million), primarily related to mid-2013 pay increases and costs associated with additional crews for the Ocean Onyx and Ocean BlackHawk and for our new rigs expected to be delivered in 2014, repair and maintenance costs ($23.7 million) and inspection costs ($10.1 million). The impact of these 2013 cost increases was partially offset by decreased costs associated with the mobilization of rigs ($21.9 million), freight ($11.5 million) and other rig operating costs ($3.3 million). Impairment of Assets. In late 2012, our management adopted a plan to actively market for sale three of our mid-water semisubmersibles, the Ocean Epoch, the Ocean New Era and the Ocean Whittington, and the jack-up rig Ocean Spartan. As a result of this decision, we recognized an impairment loss of $62.4 million in the fourth quarter of 2012 to write down the aggregate net book value of these rigs to their estimated recoverable amounts. Interest Expense. Interest expense decreased $21.4 million in 2013, compared to 2012, primarily due to a $36.6 million increase in interest capitalized on eligible construction projects during 2013, partially offset by incremental interest expense of $7.0 million for the senior unsecured notes that we issued in 2013 and an increase of $7.7 million in interest expense associated with uncertain tax positions, primarily in the Mexico tax jurisdiction. Income Tax Expense Our effective tax rate for 2013 was 29.1%, compared to a 21.5% effective tax rate for 2012. The higher effective tax rate in 2013 was due to differences in the mix of our domestic and international pre-tax earnings and losses, as well as the mix of international tax jurisdictions in which we operated. Income tax expense for 2013 was also negatively impacted by a provision of $56.9 million related to an uncertain tax position in Egypt, partially offset by the recognition of the impact of The American Taxpayer Relief Act of 2012, which reduced 2013 income tax expense by $27.5 million. As our rigs frequently operate in different tax jurisdictions as they move from contract to contract, our effective tax rate can fluctuate substantially and our historical effective tax rates may not be sustainable and could increase materially. See “Risk Factors – Changes in tax laws, effective income tax rates or adverse outcomes resulting from examination of our tax returns could adversely affect our financial results” in Item 1A of this report. 1 4 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Contract Drilling Revenue and Expense by Equipment Type 2014 Compared to 2013 Ultra-Deepwater Floaters. Revenue generated by our ultra-deepwater floaters increased $133.1 million during 2014, compared to 2013, primarily due to higher average daily revenue earned ($219.0 million), partially offset by the unfavorable effect of 241 fewer revenue earning days ($85.9 million). Average daily revenue increased primarily due to several of our ultra-deepwater floaters earning higher dayrates during 2014, compared to those earned in the prior year period, as well as incremental amortization of $50.6 million in mobilization and contract preparation fees, including amounts recognized in connection with contracts for the Ocean Monarch in Indonesia ($11.3 million), the Ocean Endeavor in Romania ($22.4 million) and the Ocean Clipper in Colombia ($8.8 million). Revenue earning days decreased during 2014, compared to the prior year, primarily due to incremental downtime for planned inspections and shipyard projects (366 additional days), including the Ocean Confidence life-extension project, non-revenue earning days between contracts (241 additional days) and rig mobilizations (95 additional days), partially offset by a reduction in unscheduled downtime for repairs (273 fewer days) and 189 revenue earning days for the Ocean BlackHawk, which was placed in service in 2014. Contract drilling expense for our ultra-deepwater fleet decreased $2.1 million in 2014, compared to 2013, as incremental operating costs for the Ocean BlackHawk ($44.8 million) were mostly offset by lower operating costs for the Ocean Confidence ($48.3 million) as a result of the rig’s life-extension project, which began in the second quarter of 2014. Deepwater Floaters. Revenue generated by our deepwater floaters decreased $122.8 million during 2014 compared 2013, primarily due to 324 fewer revenue earning days ($130.6 million), partially offset by higher average daily revenue earned ($7.8 million), which reflected an increase in amortized mobilization and contract preparation revenue associated with the Ocean America’s Australia contract. Revenue earning days decreased primarily due to unplanned downtime attributable to the warm stacking of rigs between contracts (533 additional days) and incremental downtime for planned surveys and shipyard projects (85 additional days) and rig mobilizations (46 additional days), partially offset by 333 incremental revenue earning days for the Ocean Onyx during 2014. Contract drilling expense incurred by our deepwater floaters increased $24.2 million during 2014, compared to the prior year, primarily due to incremental operating costs for the Ocean Onyx ($31.5 million), costs associated with a five- year survey for the Ocean Alliance ($18.2 million) and the mobilization of the Ocean Star to the GOM ($8.8 million). These 2014 cost increases were partially offset by reductions in costs for international shorebase locations ($9.7 million), labor 4 2 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E and personnel ($6.0 million), repairs and maintenance ($9.2 million), inspections ($4.0 million), agency fees ($1.8 million), and other rig-related costs ($3.5 million), as a result of lower rig utilization compared to the prior year and relocation of rigs. Mid-Water Floaters. Revenue generated by our mid-water floaters decreased $121.1 million during 2014, compared to the prior year, primarily as a result of 217 fewer revenue earning days ($62.2 million) and lower average daily revenue earned ($58.9 million). The decline in revenue earning days for 2014 reflected a 652-day increase in unplanned downtime, primarily due to the cold stacking of rigs, unpaid equipment repairs and downtime between contracts, partially offset by a 435-day reduction in planned downtime for shipyard projects and regulatory inspections. Average daily revenue earned during 2014 decreased compared to the prior year, primarily due to lower amortized mobilization and contract preparation revenue ($35.9 million) and a significantly lower dayrate earned by the Ocean Quest operating in Vietnam, partially offset by higher dayrates earned by our North Sea rigs. Contract drilling expense for our mid-water fleet decreased $69.4 million during 2014, compared to 2013, primarily due to reductions in costs for our currently cold stacked rigs and other mid-water rigs scrapped during the year or other non-working rigs designated for scrapping at the end of 2014 ($46.3 million) and the Ocean Patriot, which was out of service until the fourth quarter of 2014 for an enhancement project and contract preparation activities ($9.6 million). In addition, contract drilling expense incurred by our actively-marketed mid-water fleet in 2014, compared to the prior year, reflected lower aggregate costs for shipyard projects and regulatory inspections ($24.4 million) and mobilization of rigs ($14.5 million), partially offset by higher labor and personnel costs ($23.4 million). Jack-ups. Contract drilling revenue for our jack-up fleet increased $4.4 million during 2014, compared to the prior year, primarily due to an increase in average daily revenue earned ($13.7 million), as a result of higher dayrates earned by several of our jack-up rigs during 2014, partially offset by 104 fewer revenue earning days compared to 2013 ($9.3 million). Contract drilling expense decreased $3.9 million in 2014, compared to 2013, primarily due to lower costs associated the mobilization of rigs ($6.6 million), partially offset by higher labor and personnel-related costs ($3.4 million). 2013 Compared to 2012 Ultra-Deepwater Floaters. Revenue generated by our ultra-deepwater floaters decreased $48.3 million in 2013, compared to 2012, primarily due to lower average daily revenue earned ($17.7 million) and 83 fewer revenue earning days ($30.6 million). Average daily revenue decreased in 2013, compared to 2012, primarily due to a contract extension for the Ocean Rover during the second quarter of 2012 at a significantly lower dayrate than previously earned, lower revenue earned by the Ocean Clipper as a result of incremental revenue earning days at a reduced performance rate, equipment penalties assessed against revenue and the absence of additional revenue associated with the rig working outside its normal operating zone and a $17.9 million decrease in amortized mobilization revenue. However, average daily revenue for 2013 was favorably impacted by $25.0 million in revenue recognized in connection with the Settlement Agreement. Total revenue earning days for our ultra-deepwater floaters decreased during 2013, compared to 2012, primarily due to incremental unplanned downtime (225 additional days), partially offset by a reduction in downtime for shipyard projects and inspections (128 fewer days) and mobilization of rigs (21 fewer days). Contract drilling expense incurred by our ultra-deepwater floaters decreased $6.8 million during 2013, compared to 2012, primarily due to lower amortized mobilization costs ($21.8 million) and freight costs ($8.8 million), partially offset by higher costs associated with rig personnel ($18.8 million) and repairs and maintenance ($5.1 million). Deepwater Floaters. Revenue generated by our deepwater floaters increased $19.4 million during 2013, compared to 2012, as a result of higher average daily revenue earned ($47.3 million), partially offset by 75 fewer revenue earning days ($27.9 million). Average daily revenue earned by our deepwater floaters during 2013 increased primarily due to both the Ocean Valiant and Ocean Victory working at significantly higher dayrates than those earned in 2012, partially offset by lower amortized mobilization revenue ($5.4 million) during 2013. In contrast, total revenue earning days for our deepwater floaters declined in 2013 due to incremental unscheduled downtime for repairs (32 additional days), scheduled 3 4 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I shipyard projects (26 additional days) and mobilization of the Ocean America (14 days). Contract drilling expense increased $14.6 million in 2013, compared to 2012, reflecting higher labor and other personnel-related costs ($8.4 million), shorebase support costs and overheads ($5.2 million), and repair and maintenance costs ($2.1 million), partially offset by lower costs associated with the mobilization of rigs ($4.0 million). Mid-Water Floaters. Revenue generated by our mid-water floaters decreased $77.1 million during 2013, compared to 2012, primarily as a result of 453 fewer revenue earning days ($124.4 million), partially offset by the effect of higher average daily revenue earned ($47.3 million). The decrease in revenue earning days during 2013 was primarily due to an increase in planned downtime for shipyard inspections and projects (322 additional days), non-revenue earning days associated with the Niko and OGX contracts (136 days) and additional non-operating days for the Ocean Whittington (102 additional days), offset by fewer days for the mobilization of rigs (114 fewer days). Average daily revenue increased in 2013, compared to 2012, primarily due to new contracts or contract renewals for the Ocean General, Ocean Patriot, Ocean Nomad and Ocean Vanguard at higher dayrates than previously earned. Contract drilling expense remained relatively consistent in 2013 compared to 2012, increasing only $2.1 million. During 2013, our mid-water floaters benefited from cost reductions associated with the cold stacking of the Ocean Whittington and return of the Ocean Ambassador to the GOM ($47.4 million), combined with the absence of costs associated with the 2012 demobilization of the Ocean Guardian from the Falkland Islands ($12.1 million) and repair and maintenance activities after arriving in the U.K. ($7.2 million). However, cost reductions were offset by higher contract drilling expenses for the remainder of our mid-water fleet, primarily for labor and other personnel-related costs ($8.7 million), repairs and maintenance ($18.8 million), inspections ($13.0 million) and mobilization of rigs ($21.6 million). Jack-ups. Contract drilling revenue and expense for our jack-up rigs increased $13.5 million and $8.6 million, respectively, in 2013, compared to 2012. The Ocean King, which was warm stacked in Montenegro in 2010, returned to the GOM in early 2013 and commenced operations in the second quarter. During 2013, the Ocean King earned revenue and incurred incremental contract drilling expense of $26.2 million and $14.1 million, respectively, compared to 2012. The increase in both contract drilling revenue and expense for our jack-up fleet during 2013 was partially offset by the absence of $5.4 million in revenue and $8.4 million in costs attributable to our six jack-up rigs that we sold in 2012. Revenues in 2013 were further reduced as a result of 81 incremental days of scheduled downtime for repairs for the Ocean Scepter and Ocean Nugget ($9.5 million). Liquidity and Capital Resources We have historically relied principally on our cash flows from operations and cash reserves to meet liquidity needs and fund our cash requirements. In addition, we currently have available a syndicated 5-Year Revolving Agreement, or Credit Agreement, to meet our short-term and long-term liquidity needs. See “— Credit Agreement, Senior Notes and Commercial Paper Program.” At the date of this report, our contract drilling backlog was $6.8 billion, of which $2.3 billion is expected to be realized in 2015. At December 31, 2014, 2013 and 2012, we had cash available for current operations as follows: December 31, 2014 2013 2012 (In thousands) Cash and equivalents . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $233,623 $ 347,011 $ 335,432 Marketable securities . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16,033 1,750,053 1,150,158 Total cash available for current operations . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $249,656 $2,097,064 $1,485,590 A substantial portion of our cash flows has been and is expected to continue to be invested in the enhancement of our drilling fleet. We determine the amount of cash required to meet our capital commitments by evaluating our rig construction obligations, the need to upgrade rigs to meet specific customer requirements and our ongoing rig equipment enhancement/replacement programs. 4 4 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E Certain of our international rigs are owned and operated, directly or indirectly, by DOIL, and, as a result of our intention to indefinitely reinvest the earnings of DOIL to finance our foreign activities, we do not expect such earnings to be available for distribution to our stockholders or to finance our domestic activities. See “— Market Overview — Critical Accounting Estimates — Income Taxes.” We expect to utilize the operating cash flows generated by and cash reserves of DOIL and the operating cash flows available to and cash reserves of Diamond Offshore Drilling, Inc., or DODI, to meet each entity’s respective working capital requirements and capital commitments. However, in light of the significant cash requirements of our capital expansion program in 2015 and 2016, we may also make use of our credit facility or commercial paper program to finance our capital expenditures and working capital requirements. In addition, we will make periodic assessments of our capital spending programs based on industry conditions and make adjustments thereto if required. See “— Cash Flow and Capital Expenditures — Contractual Cash Obligations — Rig Construction” and “—Credit Agreement, Senior Notes and Commercial Paper Program — $1.5 Billion Revolving Credit Agreement.” We pay dividends at the discretion of our Board of Directors, or Board, and, in recent years, we have paid both regular quarterly and special cash dividends. See “Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities – Dividend Policy” in Item 5 of this report. During the three-year period ended December 31, 2014, we paid regular cash dividends totaling $207.8 million and special cash dividends totaling $1.2 billion. Our Board has adopted a policy of considering paying special cash dividends, in amounts to be determined, on a quarterly basis. Any determination to declare a dividend, as well as the amount of any dividend that may be declared, will be based on the Board’s consideration of our financial position, earnings, earnings outlook, capital spending plans, outlook on current and future market conditions and business needs and other factors that our Board of Directors considers relevant at that time. Our dividend policy may change from time to time, and there can be no assurance that we will continue to declare any cash dividends at all or in any particular amounts. On February 6, 2015, we declared a regular cash dividend of $0.125 per share of our common stock payable on March 2, 2015 to stockholders of record on February 20, 2015. See “Risk Factors — Although we have paid cash dividends in the past, we will not pay a special dividend in the first quarter of 2015, we may not pay regular or special cash dividends in the future and we can give no assurance as to the amount or timing of the payment of any future regular or special cash dividends” in Item 1A of this report, which is incorporated herein by reference. Depending on market conditions, we may, from time to time, purchase shares of our common stock in the open market or otherwise. During the year ended December 31, 2014, we repurchased 1,895,561 shares of our outstanding common stock at a cost of $87.8 million. We did not repurchase any shares of our outstanding common stock during 2013 or 2012. In addition, Loews has informed us that, depending on market and other conditions, it may, from time to time, purchase shares of our common stock in the open market or otherwise. During the year ended December 31, 2014, Loews purchased 1,879,600 shares of our common stock. Loews did not purchase any shares of our outstanding common stock during 2013 or 2012. During the three-year period ended December 31, 2014, our primary source of cash was an aggregate $3.4 billion generated from operating activities, $987.8 million net proceeds from the issuance of senior notes in 2013, $148.4 million received from the sale of drillings rig in 2012 and 2014 and $885.7 million net proceeds from the maturity of marketable securities, net of purchases. Cash usage during the same period was primarily for capital expenditures ($3.7 billion), payment of dividends and anti-dilution payments to stock plan participants ($1.5 billion), repayment of long-term debt ($250.0 million) and the acquisition of treasury stock ($87.8 million). We may, from time to time, issue debt or equity securities, or a combination thereof, to finance capital expenditures, the acquisition of assets and businesses or for general corporate purposes. Our ability to access the capital markets by issuing debt or equity securities will be dependent on our results of operations, our current financial condition, current credit ratings, current market conditions and other factors beyond our control. 5 4 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Cash Flow and Capital Expenditures Our cash flow from operations and capital expenditures for each of the years in the three-year period ended December 31, 2014 were as follows: Year Ended December 31, 2014 2013 2012 (In thousands) Cash flow from operations . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 992,831 $1,065,988 $1,311,269 Capital expenditures: Drillship construction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $1,318,271 $ 130,268 $ 248,346 Construction of deepwater floaters . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 168,045 Construction of ultra-deepwater floater . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Cash flow from operations decreased approximately $73.2 million during 2014, compared to 2013, primarily due to higher cash payments for contract drilling expenses ($77.0 million) and higher interest paid on our senior notes ($50.8 million) related to interest paid on our $1.0 billion in debt issued in November 2013 and an early interest payment for our 4.875% senior notes due July 1, 2015, or 2015 Notes. The increase in cash outflows for 2014 was partially offset by lower income taxes paid, in the U.S. federal jurisdiction, net of refunds, and a slight increase in cash receipts from contract drilling services ($6.5 million). Cash flow from operations decreased approximately $245.3 million during 2013, compared to 2012, primarily due to a $165.3 million decrease in cash receipts from contract drilling services and higher cash payments for contract drilling expenses of $83.2 million, partially offset by lower cash income taxes paid, net of refunds, of $3.3 million. See “— Results of Operations — Years Ended December 31, 2014, 2013 and 2012.” Capital Expenditures. As of the date of this report, we expect capital expenditures for 2015 to aggregate approximately $944.0 million, of which we expect to spend approximately $602.0 million on our current rig construction projects, including the Ocean Confidence service-life-extension project and an estimated $342.0 million for our ongoing capital maintenance and replacement programs. See “— Contractual Cash Obligations — Rig Construction.” We expect to fund our 2015 capital spending from the operating cash flows generated by and cash reserves of DOIL and the operating cash flows available to and cash reserves of DODI, as well as borrowings under our Credit Agreement or issuance of commercial paper. Contractual Cash Obligations — Rig Construction As of the date of this report, we have two rigs under construction in Ulsan, South Korea and are obligated under separate construction agreements with Hyundai Heavy Industries Co., Ltd., or Hyundai, for the construction of these two rigs. See Note 12 “Commitments and Contingencies” to our Consolidated Financial Statements included in Item 8 of this report for further discussion of these projects. 4 6 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E The following is a summary of our construction projects as of December 31, 2014: Project New Rig Construction: Drillship: Expected Delivery (1) Total Project Cost (2) Project Expenditures (3) Capitalized Interest 2015 (4) Actual Inception-to-Date (In millions) Ocean BlackLion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(5) Construction milestone payment to Hyundai of approximately $395 million is expected to be paid in the first quarter of 2015 upon delivery of the Ocean BlackLion. Credit Agreement, Senior Notes and Commercial Paper Program $1.5 Billion Revolving Credit Agreement. Our Credit Agreement provides for a $1.5 billion senior unsecured revolving credit facility, for general corporate purposes, which matures on October 22, 2019, except for $40 million of commitments that mature on March 17, 2019. We also have the option to increase the revolving commitments under the Credit Agreement by up to an additional $500 million from time to time, upon receipt of additional commitments from new or existing lenders, and to request up to two additional one-year extensions of the maturity date. The entire amount of the facility is available, subject to its terms, for revolving loans. Up to $250 million of the facility may be used for the issuance of performance or other standby letters of credit and up to $100 million may be used for swingline loans. As of December 31, 2014, there were no loans or letters of credit outstanding under the Credit Agreement. Commercial Paper Program. In February 2015, we established a commercial paper program with three commercial paper dealers pursuant to which we may issue, on a private placement basis, unsecured commercial paper notes up to a maximum aggregate amount outstanding at any time of $1.5 billion. Proceeds from issuances under the commercial paper program may be used for general corporate purposes. The maturities of the notes may vary, but may not exceed 397 days from the date of issuance. The notes will be issued, at our option, either at a discounted price to their principal face value or will bear interest, which may be at a fixed or floating rate, at rates that will vary based on market conditions and the ratings assigned by credit rating agencies at the time of issuance. The notes are not redeemable or subject to voluntary prepayment by us prior to maturity. Our Credit Agreement provides liquidity for our payment obligations in respect of the notes issued under the commercial paper program, and unless we change the terms of the program, the aggregate amount of notes outstanding at any time will not exceed the amount available under the Credit Agreement. As of the date of this report, we had no commercial paper notes outstanding. 7 4 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Senior Notes. Our senior notes are comprised of the following: Debt Issue Principal Amount (In millions) Maturity Date Stated Interest Rate Semiannual Interest Payment Dates 4.875% Senior Notes due 2015 . . . . . . . . . . . . . . . . . . . . 5.875% Senior Notes due 2019 . . . . . . . . . . . . . . . . . . . . 3.45% Senior Notes due 2023 . . . . . . . . . . . . . . . . . . . . . 5.70% Senior Notes due 2039 . . . . . . . . . . . . . . . . . . . . . 4.875% Senior Notes due 2043 . . . . . . . . . . . . . . . . . . . . $250.0 $500.0 $250.0 $500.0 $750.0 July 1, 2015 May 1, 2019 November 1, 2023 October 15, 2039 November 1, 2043 January 1 and July 1 4.875% 5.875% May 1 and November 1 3.45% May 1 and November 1 5.70% April 15 and October 15 4.875% May 1 and November 1 Our 4.875% Senior Notes, due 2015, in the aggregate principal amount of $250.0 million, will mature on July 1, 2015. See Note 10 “Credit Agreement and Senior Notes” to our Consolidated Financial Statements in Item 8 of this report. Credit Ratings. During the third quarter of 2014, S&P revised its outlook on us to negative and, in December 2014, lowered our corporate credit and unsecured debt rating to A- from A. In February 2015, Moody’s Investors Services, or Moody’s, and S&P assigned short-term credit ratings of Prime-2 and A2, respectively, to our commercial paper program. Concurrently, Moody’s and S&P affirmed our long-term corporate credit rating of A3 and A-, respectively. Market conditions and other factors, many of which are outside of our control, could cause our credit ratings to be lowered. A downgrade in our credit ratings could impact our cost of issuing additional debt and the amount of additional debt that we could issue. A series of downgrades or a substantial downgrade could restrict our access to capital markets and our ability to raise additional debt or rollover existing maturities. As a consequence, we may not be able to issue additional debt in amounts and/or with terms that we consider to be reasonable. One or more of these occurrences could limit our ability to pursue other business opportunities. Contractual Cash Obligations The following table sets forth our contractual cash obligations at December 31, 2014.

See further information regarding these contracts in “Quantitative and Qualitative Disclosures About Market Risk — Foreign Exchange Risk” in Item 7A of this report and Note 7 “Derivative Financial Instruments” to our Consolidated Financial Statements in Item 8 of this report. (2) The above table excludes $50.5 million of unrecognized tax benefits related to uncertain tax positions as of December 31, 2014 and an additional $37.6 million and $7.5 million for potential penalties and interest, respectively, related to such uncertain tax positions. Due to the high degree of uncertainty regarding the timing of future cash outflows associated with the liabilities recognized in these balances, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities. Except for the construction contracts discussed above and referred to in the preceding table, we had no other purchase obligations for major rig upgrades or any other significant obligations at December 31, 2014, except for those related to our direct rig operations, which arise during the normal course of business. 4 8 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E Other Commercial Commitments — Letters of Credit We were contingently liable as of December 31, 2014 in the amount of $99.6 million under certain performance, bid, supersedeas and customs bonds and letters of credit. Agreements relating to approximately $92.0 million of performance, security, supersedeas and customs bonds can require collateral at any time. As of December 31, 2014, we had not been required to make any collateral deposits with respect to these agreements. The remaining agreements cannot require collateral except in events of default. Banks have issued letters of credit on our behalf securing certain of these bonds. The table below provides a list of these obligations in U.S. dollar equivalents and their time to expiration.

Other Currency Risk. Some of our subsidiaries conduct a portion of their operations in the local currency of the country where they conduct operations. Currency environments in which we have significant business operations include Brazil, the U.K., Australia and Mexico. When possible, we attempt to minimize our currency exchange risk by seeking international contracts payable to us in local currency in amounts equal to our estimated operating costs payable in local currency, with the balance of the contract payable in U.S. dollars. At present, however, only a limited number of our contracts are payable both in U.S. dollars and the local currency. To the extent that we are not able to cover our local currency operating costs with customer payments in the local currency, we may also utilize FOREX contracts to reduce our currency exchange risk. Our FOREX contracts may obligate us to exchange predetermined amounts of specified foreign currencies at specified foreign exchange rates on specific dates or to net settle the spread between the contracted foreign currency exchange rate and the spot rate on the contract settlement date, which, for most of our contracts, is the average spot rate for the contract period. We record currency transaction gains and losses as “Foreign currency transaction gain (loss)” in our Consolidated Statements of Operations. Gains and losses arising from the settlement of our FOREX contracts that have been designated as cash flow hedges are reported as a component of “Contract drilling, excluding depreciation” expense in our Consolidated Statements of Operations. Forward-Looking Statements We or our representatives may, from time to time, either in this report, in periodic press releases or otherwise, make or incorporate by reference certain written or oral statements that are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. Forward-looking statements include, without limitation, any statement that may project, indicate or imply future results, events, performance or achievements, and may contain or be identified by the words “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate,” “believe,” “should,” “could,” “may,” “might,” “will,” “will be,” “will continue,” “will likely result,” “project,” “forecast,” “budget” and similar expressions. In addition, 9 4 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I any statement concerning future financial performance (including, without limitation, future revenues, earnings or growth rates), ongoing business strategies or prospects, and possible actions taken by or against us, which may be provided by management, are also forward-looking statements as so defined. Statements made by us in this report that contain forward-looking statements may include, but are not limited to, information concerning our possible or assumed future results of operations and statements about the following subjects: (cid:129) market conditions and the effect of such conditions on our future results of operations; (cid:129) sources and uses of and requirements for financial resources; (cid:129) interest rate and foreign exchange risk; (cid:129) contractual obligations; (cid:129) operations outside the United States; (cid:129) business strategy; (cid:129) growth opportunities; (cid:129) competitive position; (cid:129) expected financial position; (cid:129) cash flows and contract backlog; (cid:129) declaration and payment of regular or special dividends; (cid:129) financing plans; (cid:129) market outlook; (cid:129) tax planning; (cid:129) debt levels and the impact of changes in the credit markets and credit ratings for our debt; (cid:129) budgets for capital and other expenditures; (cid:129) timing and duration of required regulatory inspections for our drilling rigs; (cid:129) timing and cost of completion of rig upgrades, construction projects and other capital projects; (cid:129) delivery dates and drilling contracts related to rig conversion or upgrade projects, construction projects, other capital projects or rig acquisitions; (cid:129) plans and objectives of management; (cid:129) idling drilling rigs or reactivating stacked rigs; (cid:129) scrapping retired rigs; (cid:129) assets held for sale; (cid:129) asset impairments and impairment evaluations; 5 0 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E (cid:129) effective date and performance of contracts; (cid:129) outcomes of legal proceedings; (cid:129) compliance with applicable laws; and (cid:129) availability, limits and adequacy of insurance or indemnification. These types of statements are based on current expectations about future events and inherently are subject to a variety of assumptions, risks and uncertainties, many of which are beyond our control, that could cause actual results to differ materially from those expected, projected or expressed in forward-looking statements.

The risks and uncertainties included here are not exhaustive. Other sections of this report and our other filings with the SEC include additional factors that could adversely affect our business, results of operations and financial performance. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements.

New Accounting Pronouncements For a discussion of recent accounting pronouncements, which are not yet effective, and their effect on our financial position, results of operations and cash flows, see Note 1 “General Information — Recent Accounting Pronouncements” to our Consolidated Financial Statements in Item 8 of this report. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. The information included in this Item 7A is considered to constitute “forward-looking statements” for purposes of the statutory safe harbor provided in Section 27A of the Securities Act and Section 21E of the Exchange Act. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Forward-Looking Statements” in Item 7 of this report. Our measure of market risk exposure represents an estimate of the change in fair value of our financial instruments. Market risk exposure is presented for each class of financial instrument held by us at December 31, 2014 and 2013, assuming immediate adverse market movements of the magnitude described below. We believe that the various rates of adverse market movements represent a measure of exposure to loss under hypothetically assumed adverse conditions. The estimated market risk exposure represents the hypothetical loss to future earnings and does not represent the maximum possible loss or any expected actual loss, even under adverse conditions, because actual adverse fluctuations would likely differ. In addition, since our investment portfolio is subject to change based on our portfolio management strategy as well as in response to changes in the market, these estimates are not necessarily indicative of the actual results that may occur. Exposure to market risk is managed and monitored by our senior management. Senior management approves the overall investment strategy that we employ and has responsibility to ensure that the investment positions are consistent with that strategy and the level of risk acceptable to us. We may manage risk by buying or selling instruments or entering into offsetting positions. Interest Rate Risk We have exposure to interest rate risk arising from changes in the level or volatility of interest rates. Our investments in marketable securities are primarily in fixed maturity securities. We monitor our sensitivity to interest rate risk by evaluating the change in the value of our financial assets and liabilities due to fluctuations in interest rates. The evaluation is performed by applying an instantaneous change in interest rates by varying magnitudes on a static balance sheet to determine the effect such a change in rates would have on the recorded market value of our investments and the resulting effect on stockholders’ equity. The analysis presents the sensitivity of the market value of our financial instruments to selected changes in market rates and prices which we believe are reasonably possible over a one-year period. The sensitivity analysis estimates the change in the market value of our interest sensitive assets and liabilities that were held on December 31, 2014 and 2013, due to instantaneous parallel shifts in the yield curve of 100 basis points, with all other variables held constant. The interest rates on certain types of assets and liabilities may fluctuate in advance of changes in market interest rates, while interest rates on other types may lag behind changes in market rates. Accordingly, the analysis may not be indicative of, is not intended to provide, and does not provide a precise forecast of the effect of changes in market interest rates on our earnings or stockholders’ equity. Further, the computations do not contemplate any actions we could undertake in response to changes in interest rates. Our long-term debt, as of December 31, 2014 and 2013, is denominated in U.S. dollars. Our existing debt has been issued at fixed rates, and as such, interest expense would not be impacted by interest rate shifts. The impact of a 100-basis point increase in interest rates on fixed rate debt would result in a decrease in market value of $176.8 million and $221.5 million as of December 31, 2014 and 2013, respectively. A 100-basis point decrease would result in an increase in market value of $210.6 million and $264.5 million as of December 31, 2014 and 2013, respectively. 3 5 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I Foreign Exchange Risk Foreign exchange rate risk arises from the possibility that changes in foreign currency exchange rates will impact the value of financial instruments. It is customary for us to enter into FOREX contracts in the normal course of business. These contracts generally require us to net settle the spread between the contracted foreign currency exchange rate and the spot rate on the contract settlement date, which for most of our contracts is the average spot rate for the contract period. As of December 31, 2014, we had FOREX contracts outstanding in the aggregate notional amount of $70.2 million, consisting of $8.2 million in Australian dollars, $15.9 million in Brazilian reais, $31.3 million in British pounds sterling and $14.8 million in Mexican pesos. These contracts generally settle monthly through September 2015. At December 31, 2014, we have presented the fair value of our outstanding FOREX contracts as a current liability of $(5.4) million in “Accrued liabilities” in our Consolidated Balance Sheets included in Item 8 of this report. We have presented the fair value of our outstanding FOREX contracts at December 31, 2013, as a current asset of $1.6 million in “Prepaid expenses and other current assets” and a current liability of $(1.1) million in “Accrued liabilities” in our Consolidated Balance Sheets included in Item 8 of this report.

Financial Statements and Supplementary Data. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of Diamond Offshore Drilling, Inc. and Subsidiaries Houston, Texas We have audited the accompanying consolidated balance sheets of Diamond Offshore Drilling, Inc. and subsidiaries (the “Company”) as of December 31, 2014 and 2013, and the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2014. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Diamond Offshore Drilling, Inc. and subsidiaries at December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control —Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 23, 2015, expressed an unqualified opinion on the Company’s internal control over financial reporting. Houston, Texas February 23, 2015 /s/ Deloitte & Touche LLP 5 5 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of Diamond Offshore Drilling, Inc. and Subsidiaries Houston, Texas We have audited the internal control over financial reporting of Diamond Offshore Drilling, Inc. and subsidiaries (the “Company”) as of December 31, 2014, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A of this Form 10-K under the heading “Management’s Annual Report on Internal Control Over Financial Reporting.” Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company as of and for the year ended December 31, 2014 and our report dated February 23, 2015 expressed an unqualified opinion on those financial statements. /s/ Deloitte & Touche LLP Houston, Texas February 23, 2015 5 6 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1 . G e n e r a l In f o r m a t i o n Diamond Offshore Drilling, Inc. is a leader in offshore drilling, providing contract drilling services to the energy industry around the globe with a fleet of 38 offshore drilling rigs, excluding three mid-water semisubmersible rigs which we plan to retire and scrap. Our current fleet, excluding the retired units, consists of 27 semisubmersibles, one of which is under construction, six jack-ups and five dynamically positioned drillships, one of which is under construction. Unless the context otherwise requires, references in these Notes to “Diamond Offshore,” “we,” “us” or “our” mean Diamond Offshore Drilling, Inc. and our consolidated subsidiaries. We were incorporated in Delaware in 1989. As of February 16, 2015, Loews Corporation, or Loews, owned 52.5% of the outstanding shares of our common stock. Principles of Consolidation Our consolidated financial statements include the accounts of Diamond Offshore Drilling, Inc. and our subsidiaries after elimination of intercompany transactions and balances. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States, or U.S., or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimated. Cash and Cash Equivalents We consider short-term, highly liquid investments that have an original maturity of three months or less and deposits in money market mutual funds that are readily convertible into cash to be cash equivalents. We had bank deposits denominated in Egyptian pounds totaling $7.3 million and $14.3 million at December 31, 2014 and 2013, respectively. However, the local currency is not readily convertible into U.S. dollars or other currencies at this time. We expect to use a portion of these amounts to fund local obligations in Egyptian pounds in the short term and have reported $7.2 million and $12.7 million, representing the excess of total bank deposits over our estimated local currency requirements for the next twelve months, as “Other assets” in our Consolidated Balance Sheets at December 31, 2014 and 2013, respectively. The effect of exchange rate changes on cash balances held in foreign currencies was not material for the years ended December 31, 2014, 2013 and 2012. Marketable Securities We classify our investments in marketable securities as available for sale and they are stated at fair value in our Consolidated Balance Sheets. Accordingly, any unrealized gains and losses, net of taxes, are reported in our Consolidated Balance Sheets in “Accumulated other comprehensive gain (loss)” until realized. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity and such adjustments are included in our Consolidated Statements of Operations in “Interest income.” The sale and purchase of securities are recorded on the date of the trade. The cost of debt securities sold is based on the specific identification method. Realized gains or losses, as well as any declines in value that are judged to be other than temporary, are reported in our Consolidated Statements of Operations in “Other income (expense) — Other, net.” 6 2 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Provision for Bad Debts We record a provision for bad debts on a case-by-case basis when facts and circumstances indicate that a customer receivable may not be collectible. In establishing these reserves, we consider historical and other factors that predict collectability, including write-offs, recoveries and the monitoring of credit quality. Such provision is reported as a component of “Operating expense” in our Consolidated Statements of Operations. See Note 3. Derivative Financial Instruments Our derivative financial instruments consist primarily of foreign currency forward exchange, or FOREX, contracts which we may designate as cash flow hedges. In accordance with GAAP, each derivative contract is stated in the balance sheet at its fair value with gains and losses reflected in the income statement except that, to the extent the derivative qualifies for and is designated as an accounting hedge, the gains and losses are reflected in income in the same period as offsetting gains and losses on the qualifying hedged positions. Designated hedges are expected to be highly effective, and therefore, adjustments to record the carrying value of the effective portion of our derivative financial instruments to their fair value are recorded as a component of “Accumulated other comprehensive gain (loss),” or AOCGL, in our Consolidated Balance Sheets. The effective portion of the cash flow hedge will remain in AOCGL until it is reclassified into earnings in the period or periods during which the hedged transaction affects earnings or it is determined that the hedged transaction will not occur. We report such realized gains and losses as a component of “Contract drilling, excluding depreciation” expense in our Consolidated Statements of Operations to offset the impact of foreign currency fluctuations in our expenditures in local foreign currencies in the countries in which we operate. Adjustments to record the carrying value of the ineffective portion of our derivative financial instruments to fair value and realized gains or losses upon settlement of derivative contracts not designated as cash flow hedges are reported as “Foreign currency transaction gain (loss)” in our Consolidated Statements of Operations. See Notes 7 and 8. Asset Held For Sale At December 31, 2013, we reported the $7.7 million carrying value of our jack-up rig, the Ocean Spartan, as “Asset held for sale” in our Consolidated Balance Sheets. The Ocean Spartan was sold in June 2014 for an aggregate selling price of $16.5 million, and we recognized a net gain of $8.5 million on the transaction. Drilling and Other Property and Equipment We carry our drilling and other property and equipment at cost. Maintenance and routine repairs are charged to income currently while replacements and betterments, including associated inspection and recertification costs, which upgrade or increase the functionality of our existing equipment and that significantly extend the useful life of an existing asset, are capitalized. Significant judgments, assumptions and estimates may be required in determining whether or not such replacements and betterments meet the criteria for capitalization and in determining useful lives and salvage values of such assets. Changes in these judgments, assumptions and estimates could produce results that differ from those reported. Historically, the amount of capital additions requiring significant judgments, assumptions or estimates has not been significant. During the years ended December 31, 2014 and 2013, we capitalized $546.0 million and $302.0 million, respectively, in replacements and betterments of our drilling fleet, resulting from numerous projects ranging from $25,000 to $160 million per project. 3 6 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Costs incurred for major rig upgrades and/or the construction of rigs are accumulated in construction work-in- progress, with no depreciation recorded on the additions, until the month the upgrade or newbuild is completed and the rig is placed in service. Upon retirement or sale of a rig, the cost and related accumulated depreciation are removed from the respective accounts and any gains or losses are included in our results of operations as “Gain on disposition of assets.” Depreciation is recognized up to applicable salvage values by applying the straight-line method over the remaining estimated useful lives from the year the asset is placed in service. Drilling rigs and equipment are depreciated over their estimated useful lives ranging from 3 to 30 years. Capitalized Interest We capitalize interest cost for qualifying construction and upgrade projects. During the three years ended December 31, 2014, we capitalized interest on qualifying expenditures, primarily related to our rig construction projects. See Note 9. A reconciliation of our total interest cost to “Interest expense” as reported in our Consolidated Statements of Operations is as follows: Total interest cost including amortization of debt issuance costs . . . . . . . . . . $122,656 $ 99,080 $ 83,890 Capitalized interest . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We utilize an undiscounted probability-weighted cash flow analysis in testing an asset for potential impairment. Our assumptions and estimates underlying this analysis include the following: (cid:129) dayrate by rig; (cid:129) utilization rate by rig (expressed as the actual percentage of time per year that the rig would be used); (cid:129) the per day operating cost for each rig if active, warm stacked or cold stacked; (cid:129) the estimated annual cost for rig replacements and/or enhancement programs; (cid:129) the estimated maintenance, inspection or other costs associated with a rig returning to work; (cid:129) salvage value for each rig; and (cid:129) estimated proceeds that may be received on disposition of the rig. 6 4 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Based on these assumptions and estimates, we develop a matrix using several different utilization/dayrate scenarios, to each of which we have assigned a probability of occurrence. The sum of our utilization scenarios (which include active, warm stacked and cold stacked) and probability of occurrence scenarios both equal 100% in the aggregate. We reevaluate these rigs annually, by updating the matrices for each rig and modifying our assumptions, giving consideration to the length of time the rig has been cold stacked, the current and expected market for the type of rig and expectations of future oil and gas prices. See Note 2. Fair Value of Financial Instruments We believe that the carrying amount of our current financial instruments approximates fair value because of the short maturity of these instruments. See Note 8. Debt Issuance Costs Debt issuance costs are included in our Consolidated Balance Sheets in “Other assets” and are amortized over the respective terms of the related debt. Income Taxes We account for income taxes in accordance with accounting standards that require the recognition of the amount of taxes payable or refundable for the current year and an asset and liability approach in recognizing the amount of deferred tax liabilities and assets for the future tax consequences of events that have been currently recognized in our financial statements or tax returns. In each of our tax jurisdictions we recognize a current tax liability or asset for the estimated taxes payable or refundable on tax returns for the current year and a deferred tax asset or liability for the estimated future tax effects attributable to temporary differences and carryforwards. Deferred tax assets are reduced by a valuation allowance, if necessary, which is determined by the amount of any tax benefits that, based on available evidence, are not expected to be realized under a “more likely than not” approach. We make judgments regarding future events and related estimates especially as they pertain to the forecasting of our effective tax rate, the potential realization of deferred tax assets such as utilization of foreign tax credits, and exposure to the disallowance of items deducted on tax returns upon audit. We record interest related to accrued unrecognized tax positions in interest expense and recognize penalties associated with uncertain tax positions in our tax expense. See Note 14. Treasury Stock Depending on market conditions, we may, from time to time, purchase shares of our common stock in the open market or otherwise. We account for the purchase of treasury stock using the cost method, which reports the cost of the shares acquired in “Treasury stock” as a deduction from stockholders’ equity in our Consolidated Balance Sheets. During the year ended December 31, 2014, we repurchased 1,895,561 shares of our outstanding common stock at a cost of $87.8 million. We did not repurchase any shares of our outstanding common stock during 2013 or 2012. Comprehensive Income (Loss) Comprehensive income (loss) is the change in equity of a business enterprise during a period from transactions and other events and circumstances except those transactions resulting from investments by owners and distributions to owners. Comprehensive income (loss) for the three years ended December 31, 2014, 2013 and 2012 includes net income 5 6 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) (loss) and unrealized holding gains and losses on marketable securities and financial derivatives designated as cash flow accounting hedges. See Note 11. Foreign Currency Our functional currency is the U.S. dollar. Foreign currency transaction gains and losses are reported as “Foreign currency transaction gain (loss)” in our Consolidated Statements of Operations and include, when applicable, unrealized gains and losses to record the carrying value of our FOREX contracts not designated as accounting hedges, as well as realized gains and losses from the settlement of such contracts. For the years ended December 31, 2014, 2013 and 2012, we recognized aggregate net foreign currency gains (losses) of $3.2 million, $(4.9) million and $(2.0) million, respectively. See Note 7. Revenue Recognition We recognize revenue from dayrate drilling contracts as services are performed. In connection with such drilling contracts, we may receive fees (on either a lump-sum or dayrate basis) for the mobilization of equipment. We earn these fees as services are performed over the initial term of the related drilling contracts. We defer mobilization fees received, as well as direct and incremental mobilization costs incurred, and amortize each, on a straight-line basis, over the term of the related drilling contracts (which is the period we estimate to be benefited from the mobilization activity). Straight-line amortization of mobilization revenues and related costs over the term of the related drilling contracts (which generally range from two to 60 months) is consistent with the timing of net cash flows generated from the actual drilling services performed. Absent a contract, mobilization costs are recognized currently. Upon completion of a drilling contract, we recognize in earnings any demobilization fees received and costs incurred. Some of our drilling contracts require downtime before the start of the contract to prepare the rig to meet customer requirements. At times, we may be compensated by the customer for such work (on either a lump-sum or dayrate basis). These fees are generally earned as services are performed over the initial term of the related drilling contracts. We defer contract preparation fees received, as well as direct and incremental costs associated with the contract preparation activities and amortize each, on a straight-line basis, over the term of the related drilling contracts (which we estimate to be benefited from the contract preparation activity). From time to time, we may receive fees from our customers for capital improvements to our rigs (on either a lump- sum or dayrate basis). We defer such fees received in “Accrued liabilities” and “Other liabilities” in our Consolidated Balance Sheets and recognize these fees into income on a straight-line basis over the period of the related drilling contract. We capitalize the costs of such capital improvements and depreciate them over the estimated useful life of the improvement. We record reimbursements received for the purchase of supplies, equipment, personnel services and other services provided at the request of our customers in accordance with a contract or agreement, for the gross amount billed to the customer, as “Revenues related to reimbursable expenses” in our Consolidated Statements of Operations. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2014-09, Revenue from Contracts with Customers (Topic 606), or ASU 2014-09. The new standard supersedes the industry-specific standards that currently exist under GAAP and provides a framework to address revenue recognition 6 6 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) issues comprehensively for all contracts with customers regardless of industry-specific or transaction-specific fact patterns. Under the new guidance, companies recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 also provides for additional disclosure requirements. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and may be adopted using a retrospective or modified retrospective approach. Early adoption is not permitted. We are currently evaluating the provisions of ASU 2014-09 and have not yet determined its impact on our financial position, results of operations or cash flows. 2 . A s s e t Im p a i r m e n t s During the third quarter of 2014, we initiated a plan to retire and scrap the Ocean New Era, the Ocean Epoch and the Ocean Whittington, all three of which were cold stacked and initially impaired in 2012, as well as the Ocean Concord and the Ocean Yatzy, which were idle in Brazil. We also initiated a plan to retire and scrap the Ocean Winner upon completion of its contract term in Brazil. Using the undiscounted probability-weighted cash flow analysis described in Note 1, we determined that the carrying values of the six rigs to be retired and scrapped, or the Retirement Group, were impaired. The fair values of the five non- working rigs in the Retirement Group were determined based on discussions with and a quote received from a rig broker to scrap two of the rigs. We consider this to be a Level 3 fair value measurement due to the nonbinding nature of the quote, the significant level of estimation involved and the lack of transparency as to the inputs used. The fair value of the sixth rig in the Retirement Group, the Ocean Winner (which is under contract through March 2015) was determined using an income approach, which utilized significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to estimated dayrate revenue, rig utilization and anticipated costs for the remainder of the current contract, as well as the aforementioned scrap value quote. As a result of our valuations, we recognized an impairment loss aggregating $109.5 million during the third quarter of 2014. See Note 8. During the fourth quarter of 2014, two of the rigs in the Retirement Group were scrapped. The aggregate book value of the remaining rigs in the Retirement Group was $9.4 million at December 31, 2014 and is reported in “Drilling and other property and equipment, net of accumulated depreciation” in our Consolidated Balance Sheets. At December 31, 2014, we had six rigs, in addition to the Retirement Group, which met our criteria for impairment evaluation, and we performed an impairment analysis for each of these rigs using the methodology described in Note 1. Based on our analyses, we concluded that these rigs were not impaired at December 31, 2014. We did not record any impairment for the year ended December 31, 2013. During the year ended December 31, 2012, we recognized an impairment loss of $62.4 million in connection with management’s decision at that time to market for sale four of our then cold stacked rigs. One of these rigs was sold to a third party in 2014 and the remaining three rigs were evaluated for impairment as part of the Retirement Group in 2014. See Note 1. Management’s assumptions are an inherent part of our asset impairment evaluation, and the use of different assumptions could produce results that differ from those reported. 7 6 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 4 . S t o c k - B a s e d Co m p e n s a t i o n In March 2014, our Board of Directors adopted our Equity Incentive Compensation Plan, or Equity Plan, which amended and restated our Second Amended and Restated 2000 Stock Option Plan. The Equity Plan was approved by our stockholders in May 2014. Awards that may be granted under the Equity Plan include time-vested awards and performance-based awards, which are earned on the achievement of certain performance criteria. The following types of awards may be granted under the Equity Plan: (cid:129) Stock options (including incentive stock options and nonqualified stock options); 9 6 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I (cid:129) Stock appreciation rights, or SARs; (cid:129) Restricted stock; (cid:129) Restricted stock units, or RSUs; (cid:129) Performance shares or units; and (cid:129) Other stock-based awards (including dividend equivalents). A maximum of 7,500,000 shares of our common stock is available for the grant or settlement of awards under the Equity Plan, subject to adjustment for certain business transactions and changes in capital structure. Vesting conditions and other terms and conditions of awards under the Equity Plan are determined by our Board of Directors or the compensation committee of our Board of Directors, subject to the terms of the Equity Plan. Time-Vested Awards. Stock options and SARs awarded under the Equity Plan generally vest ratably over a four-year period and expire in ten years. The exercise price per share of stock options and SARs awarded under the Equity Plan may not be less than the fair market value of our common stock on the date of grant. Total compensation cost recognized for time-vested awards under the Equity Plan (or its predecessor), consisting solely of awards of SARs, for the years ended December 31, 2014, 2013 and 2012 was $4.1 million, $3.9 million and $4.7 million, respectively. Tax benefits recognized for the years ended December 31, 2014, 2013 and 2012 related thereto were $1.4 million, $1.3 million and $1.6 million, respectively. The fair value of SARs granted under the Equity Plan (or its predecessor) during each of the years ended December 31, 2014, 2013 and 2012 was estimated using the Black Scholes pricing model. The following are the weighted average assumptions used in estimating the fair value of our SARs: Expected life of SARs (in years) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 7 6 Expected volatility . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21.68% 18.24% 33.45% Dividend yield . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.10% .75% Risk free interest rate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.08% 1.61% .78% .89% Year Ended December 31, 2014 2013 2012 7 0 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The expected life of SARs is based on historical data as is the expected volatility. The dividend yield is based on the current approved regular dividend rate in effect and the current market price at the time of grant. Risk free interest rates are determined using the U.S. Treasury yield curve at time of grant with a term equal to the expected life of the SARs. A summary of stock option and SARs activity under the Equity Plan as of December 31, 2014 and changes during the year then ended is as follows: Number of Awards Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (In Thousands) Awards outstanding at January 1, 2014 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1,392,659 Granted . . . . . . . . . . . . . . . . . . . . . . . . . . 288,675 Exercised . . . . . . . . . . . . . . . . . . . . . . . . .

The total intrinsic value of awards exercised during the years ended December 31, 2014, 2013 and 2012 was $169,000, $162,000 and $147,000, respectively. The total fair value of awards vested during the years ended December 31, 2014, 2013 and 2012 was $4.5 million, $4.1 million and $5.2 million, respectively. As of December 31, 2014 there was $3.9 million of total unrecognized compensation cost related to nonvested SARs granted under the Equity Plan which we expect to recognize over a weighted average period of two years. Performance-Based Awards. In March 2014, we awarded 52,581 targeted performance RSUs, with a volume weighted average price of our common stock preceding the grant date of $47.52 per share, to our Chief Executive Officer, or CEO, in connection with his commencement of service with us on March 3, 2014. RSUs are contractual rights to receive shares of our common stock in the future if the applicable vesting conditions are met. Targeted RSUs will become earned RSUs upon achievement of certain performance goals as set forth in the award certificate. In January 2015, the compensation committee of our Board of Directors determined that our CEO had satisfied all performance criteria required for the 52,581 target performance RSUs to become earned by him. Earned RSUs granted to our CEO will vest in one-third increments annually, over three years, commencing on the first anniversary of his hire date, with the first year being prorated for the portion of 2014 during which he was employed. As of December 31, 2014, none of the RSUs granted to our CEO had vested. Because the stock-based compensation awarded to our CEO is a fixed monetary amount at the date of grant (the target value of $3.0 million on a prorated basis) with variances based on actual achievement of a performance goal, the award is being recorded as a share-based liability. Compensation cost will be recognized over the requisite service period as specified in the award. In connection with the targeted RSUs granted in March 2014, we recognized $0.9 million in compensation expense for the year ended December 31, 2014. “Accrued liabilities” at December 31, 2014 included $0.9 million for share-based liabilities. 1 7 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC.

Our FOREX contracts generally require us to net settle the spread between the contracted foreign currency exchange rate and the spot rate on the contract settlement date, which, for most of our contracts, is the average spot rate for the contract period. We enter into FOREX contracts when we believe market conditions are favorable to purchase contracts for future settlement with the expectation that such contracts, when settled, will reduce our exposure to foreign currency gains and losses on future foreign currency expenditures. The amount and duration of such contracts is based on our monthly forecast of expenditures in the significant currencies in which we do business and for which there is a financial market (i.e., Australian dollars, Brazilian reais, British pounds sterling and Mexican pesos). These forward contracts are derivatives as defined by GAAP. During the years ended December 31, 2014, 2013 and 2012, we settled FOREX contracts with aggregate notional values of approximately $304.7 million, $307.4 million and $305.6 million, respectively, of which the entire aggregate amounts were designated as an accounting hedge. During the years ended December 31, 2014, 2013 and 2012, we did not enter into or settle any FOREX contracts that were not designated as accounting hedges. The following table presents the aggregate amount of gain or loss recognized in our Consolidated Statements of Operations related to our FOREX contracts designated as hedging instruments for the years ended December 31, 2014, 2013 and 2012.

As of December 31, 2014, all outstanding derivative contracts had been designated as cash flow hedges. We have International Swap Dealers Association, or ISDA, contracts, which are standardized master legal arrangements that establish key terms and conditions, which govern certain derivative transactions. As of December 31, 2014, our FOREX contracts were with two counterparties and were governed under such ISDA agreements. There are no requirements to post collateral under these contracts; however, they do contain credit-risk related contingent provisions including credit support provisions and the net settlement of amounts owed in the event of early terminations. Additionally, should our credit ratings fall below a specified rating immediately following the merger of Diamond Offshore Drilling, Inc. with another entity, the counterparty may require all outstanding derivatives under the ISDA contract to be settled immediately at current market value. Our ISDA arrangements also include master netting agreements to further manage counterparty credit risk associated with our FOREX contracts. We have elected not to offset the fair value amounts recorded for our derivative contracts under these agreements in our Consolidated Balance Sheets as of December 31, 2014 and 2013; however, there would have been no significant differences in our Consolidated Balance Sheets if the estimated fair values were presented on a net basis for these periods.

The agreements were settled in November 2013 upon the completion of the offering of the senior notes for a net gain of $26,728, before tax. The gain has been recorded as a component of AOCGL and is being amortized to interest expense over the terms of the respective senior unsecured notes.

The net unrealized gains (losses) associated with these derivative financial instruments will be reclassified to contract drilling expense and interest expense, respectively, to the extent fully effective. During the years ended December 31, 2014, 2013 and 2012 we did not reclassify any amounts from AOCGL due to the probability of an underlying forecasted transaction not occurring. 8 . F i n a n c i a l In s t r u m e n t s a n d F a i r V a l u e D i s c l o s u r e s Concentrations of Credit and Market Risk Financial instruments that potentially subject us to significant concentrations of credit or market risk consist primarily of periodic temporary investments of excess cash, trade accounts receivable and investments in debt securities, including mortgage-backed securities. We generally place our excess cash investments in U.S. government backed short- term money market instruments through several financial institutions. At times, such investments may be in excess of the insurable limit. We periodically evaluate the relative credit standing of these financial institutions as part of our investment strategy. 5 7 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Most of our investments in debt securities are securitized corporate bonds whereby our credit risk is mitigated by the collateral. However, we are exposed to market risk due to price volatility associated with interest rate fluctuations. Concentrations of credit risk with respect to our trade accounts receivable are limited primarily due to the entities comprising our customer base. Since the market for our services is the offshore oil and gas industry, this customer base consists primarily of major and independent oil and gas companies and government-owned oil companies. During 2014 and 2013, our largest customer in Brazil, Petróleo Brasileiro S.A., or Petrobras, (a Brazilian multinational energy company that is majority-owned by the Brazilian government), accounted for $123.3 million and $154.5 million, or 29% and 35%, respectively, of our total consolidated net trade accounts receivable balance. In general, before working for a customer with whom we have not had a prior business relationship and/or whose financial stability may be uncertain to us, we perform a credit review on that company. Based on that analysis, we may require that the customer present a letter of credit, prepay or provide other credit enhancements. We record a provision for bad debts on a case-by-case basis when facts and circumstances indicate that a customer receivable may not be collectible and, historically, losses on our trade receivables have been infrequent occurrences. During 2013, based on our assessment of the financial condition of two of our customers, Niko Resources Ltd., or Niko, and OGX Petróleo e Gás Ltda. (a privately owned Brazilian oil and natural gas company that filed for bankruptcy in October 2013), or OGX, and our expectations at the time regarding the probability of collection of amounts due to us from them, we recorded $22.5 million in bad debt expense to fully reserve all outstanding receivables owed to us. In December 2013, we entered into a settlement agreement with Niko, or the Niko Settlement, whereby Niko will be released from certain obligations under the dayrate contracts for the Ocean Monarch and Ocean Lexington, subject to and effective upon the full payment of amounts owed to us under the Niko Settlement and subject to its other conditions. In accordance with the terms of the Niko Settlement, we received cash payments of $20.3 million during 2014 and $25.0 million in the fourth quarter of 2013, which we recognized as revenue against invoices due us. Niko is further obligated to make future periodic payments to us pursuant to the Niko Settlement totaling an aggregate of $34.8 million, payable at various times through December 2016. We plan to recognize these amounts in revenue as they are received due to the uncertainty regarding their timing and collection. In 2014, the creditors of OGX, including us, agreed to a settlement whereby the creditors would receive shares of the reorganized OGX company in full settlement of obligations owed to them by OGX. As a result of the settlement, we have written off $21.2 million in receivables due us from OGX against the associated allowance for bad debts, which was set up in 2013. See Note 3. 7 6 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Fair Values Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy prescribed by GAAP requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 Quoted prices for identical instruments in active markets. Level 1 assets include short-term investments such as money market funds, U.S. Treasury Bills and Treasury notes. Our Level 1 assets at December 31, 2014 consisted of cash held in money market funds of $197.5 million and time deposits of $20.3 million. Our Level 1 assets at December 31, 2013 consisted of cash held in money market funds of $281.3 million, time deposits of $30.0 million and investments in U.S. Treasury securities of $1,749.9 million. Level 2 Quoted market prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 assets and liabilities include residential mortgage-backed securities, corporate bonds purchased in a private placement offering and over-the-counter FOREX contracts. Our residential mortgage-backed securities and corporate bonds were valued using a model-derived valuation technique based on the quoted closing market prices received from a financial institution. Our FOREX contracts were valued based on quoted market prices, which are derived from observable inputs including current spot and forward rates, less the contract rate multiplied by the notional amount. The inputs used in our valuation are obtained from a Bloomberg curve analysis which uses par coupon swap rates to calculate implied forward rates so that projected floating rate cash flows can be calculated. The valuation techniques underlying the models are widely accepted in the financial services industry and do not involve significant judgment. Level 3 Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Level 3 assets and liabilities generally include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation or for which there is a lack of transparency as to the inputs used. Our Level 3 assets at December 31, 2014 consisted of nonrecurring measurements of four mid-water semisubmersible rigs for which we recorded an impairment loss during the third quarter of 2014. See Notes 1 and 2. Market conditions could cause an instrument to be reclassified among Levels 1, 2 and 3. Our policy regarding fair value measurements of financial instruments transferred into and out of levels is to reflect the transfers as having occurred at the beginning of the reporting period. There were no transfers between fair value levels during the years ended December 31, 2014 and 2013. Certain of our assets and liabilities are required to be measured at fair value on a recurring basis in accordance with GAAP. In addition, certain assets and liabilities may be recorded at fair value on a nonrecurring basis. Generally, we record assets at fair value on a nonrecurring basis as a result of impairment charges. We recorded impairment charges 7 7 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) related to six mid-water semisubmersible rigs, which were measured at fair value on a nonrecurring basis in the third quarter of 2014, of $109.5 million and have presented the loss in “Impairment of assets” in our Consolidated Statements of Operations for the year ended December 31, 2014. We did not record any such impairment charges during the year ended December 31, 2013. See Notes 1 and 2.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) We believe that the carrying amounts of our other financial assets and liabilities (excluding long-term debt), which are not measured at fair value in our Consolidated Balance Sheets, approximate fair value based on the following assumptions: (cid:129) Cash and cash equivalents — The carrying amounts approximate fair value because of the short maturity of these instruments. (cid:129) Accounts receivable and accounts payable — The carrying amounts approximate fair value based on the nature of the instruments. We consider our senior notes, including current maturities, to be Level 2 liabilities under the GAAP fair value hierarchy and, accordingly, the fair value of our senior notes was derived using a third-party pricing service at December 31, 2014 and 2013. We perform control procedures over information we obtain from pricing services and brokers to test whether prices received represent a reasonable estimate of fair value. These procedures include the review of pricing service or broker pricing methodologies and comparing fair value estimates to actual trade activity executed in the market for these instruments occurring generally within a 10-day window of the report date. Fair values and related carrying values (see Note 10) of our senior notes are shown below.

See Note 12. 10 . Cr e dit Agr eement a nd S en io r No te s Credit Agreement We have a syndicated 5-Year Revolving Credit Agreement, or Credit Agreement, with Wells Fargo Bank, National Association, as administrative agent and swingline lender. Effective October 22, 2014, we entered into a commitment increase and extension agreement and third amendment to the Credit Agreement which, among other things, increased the aggregate commitment under the Credit Agreement from $1.0 billion to $1.5 billion and provided for an approximately seven-month extension of the maturity date for most of the lenders. In addition, pursuant to such amendment, subject to the conditions specified in the Credit Agreement, we have the option to increase the revolving commitments under the Credit Agreement by up to an additional $500 million from time to time, upon receipt of 8 0 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) additional commitments from new or existing lenders, and to request up to two additional one-year extensions of the maturity date. As so amended, the Credit Agreement provides for a $1.5 billion senior unsecured revolving credit facility for general corporate purposes, maturing on October 22, 2019, except for $40 million of commitments that mature on March 17, 2019. The entire amount of the facility is available, subject to its terms, for revolving loans. Up to $250 million of the facility may be used for the issuance of performance or other standby letters of credit and up to $100 million may be used for swingline loans. Revolving loans under the Credit Agreement bear interest, at our option, at a rate per annum based on either an alternate base rate, or ABR, or a Eurodollar Rate, as defined in the Credit Agreement, plus the applicable interest margin for an ABR loan or a Eurodollar loan. The ABR is the greatest of (i) the prime rate, (ii) the federal funds rate plus 0.50% and (iii) the daily one-month Eurodollar Rate plus 1.00%. The applicable interest margin for ABR loans varies from 0% to 0.25%. The applicable interest margin for Eurodollar loans varies between 0.75% and 1.25%. Swingline loans bear interest, at our option, at a rate per annum equal to (i) the ABR plus the applicable interest margin for ABR loans or (ii) the daily one-month Eurodollar Rate plus the applicable interest margin for Eurodollar loans. Under our Credit Agreement, we also pay, based on our current long-term credit ratings, and as applicable, other customary fees including, but not limited to, a commitment fee on the unused commitments under the Credit Agreement, varying between 0.06% and 0.20% per annum, and a fronting fee to the issuing bank for each letter of credit. Participation fees for letters of credit are dependent upon the type of letter of credit issued, varying between 0.375% and 0.625% per annum for performance letters of credit, and between 0.75% and 1.25% per annum for all other letters of credit. Changes in credit ratings could lower or raise the fees that we pay under the Credit Agreement. The Credit Agreement contains customary covenants including, but not limited to, maintenance of a ratio of consolidated indebtedness to total capitalization, as defined in the Credit Agreement, of not more than 60% at the end of each fiscal quarter, as well as limitations on liens; mergers, consolidations, liquidation and dissolution; changes in lines of business; swap agreements; transactions with affiliates; and subsidiary indebtedness.

In 2013, we issued $1.0 billion aggregate principal amount of senior notes consisting of $250.0 million aggregate principal amount of 3.45% senior unsecured notes due 2023 and $750.0 million aggregate principal amount of 4.875% senior unsecured notes due 2043 or, collectively, the New Notes, for general corporate purposes, including redemption, repurchase or retirement of our 5.15% senior notes due September 1, 2014 and our 4.875% senior notes due July 1, 2015, or 2015 Notes. The transaction resulted in net proceeds to us of $987.8 million after deducting underwriting discounts, commissions and estimated expenses. The New Notes are unsecured and unsubordinated obligations of Diamond Offshore Drilling, Inc., and rank equally in right of payment to all of its existing and future unsecured and unsubordinated indebtedness, and are effectively subordinated to all existing and future obligations of our subsidiaries. We have the right to redeem all or a portion of the New Notes for cash at any time or from time to time, on at least 15 days but not more than 60 days prior written notice, at a make-whole redemption price specified in the governing indenture (if applicable) plus accrued and unpaid interest to, but excluding, the date of redemption. 8 2 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 1 2 . Co m m i t m e n t s a n d Co n t i n g e n c i e s Various claims have been filed against us in the ordinary course of business, including claims by offshore workers alleging personal injuries. With respect to each claim or exposure, we have made an assessment, in accordance with GAAP, of the probability that the resolution of the matter would ultimately result in a loss. When we determine that an unfavorable resolution of a matter is probable and such amount of loss can be determined, we record a liability for the amount of the estimated loss at the time that both of these criteria are met. Our management believes that we have recorded adequate accruals for any liabilities that may reasonably be expected to result from these claims. Asbestos Litigation. We are one of several unrelated defendants in lawsuits filed in Mississippi and Louisiana state courts alleging that defendants manufactured, distributed or utilized drilling mud containing asbestos and, in our case, allowed such drilling mud to have been utilized aboard our offshore drilling rigs. The plaintiffs seek, among other things, an award of unspecified compensatory and punitive damages. The manufacture and use of asbestos-containing drilling mud had already ceased before we acquired any of the drilling rigs addressed in these lawsuits. We believe that we are not liable for the damages asserted and we expect to receive complete defense and indemnity from Murphy Exploration & Production Company with respect to many of the lawsuits pursuant to the terms of our 1992 asset purchase agreement with them. We also believe that we are not liable for the damages asserted in the remaining lawsuits pursuant to the terms of our 1989 asset purchase agreement with Diamond M Corporation, and we filed a declaratory judgment action in Texas state court against NuStar Energy LP, or NuStar, and Kaneb Management Co., L.L.C., or Kaneb, the successors to Diamond M Corporation, seeking a judicial determination that we did not assume liability for these claims. Trial of this declaratory judgment action is scheduled to commence in 2015. We are unable to estimate our potential exposure, if any, to these lawsuits at this time but do not believe that our ultimate liability, if any, resulting from this litigation will have a material effect on our consolidated financial condition, results of operations or cash flows. We have been named in various other lawsuits or threatened actions that are incidental to the ordinary course of our business. We intend to defend these matters vigorously; however, litigation is inherently unpredictable, and the ultimate outcome or effect of these lawsuits and actions cannot be predicted with certainty. As a result, there can be no assurance as to the ultimate outcome of these lawsuits. Any claims against us, whether meritorious or not, could cause us to incur costs and expenses, require significant amounts of management time and result in the diversion of significant operational resources. In the opinion of our management, no pending or known threatened claims, actions or proceedings against us are expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. Brazilian Withholding Contingency. In July 2014, Petrobras notified us, along with other industry participants, that it is challenging assessments by Brazilian tax authorities of withholding taxes associated with the provision of drilling rigs for its operations in Brazil during the years 2008 and 2009. Petrobras has also notified us that, if Petrobras is ultimately assessed and must pay such withholding taxes, it will seek reimbursement from us for the portion allocable to our drilling rigs. We dispute any basis for Petrobras to obtain such reimbursement, and we have notified Petrobras of our position. If necessary, we intend to defend any reimbursement claims against us vigorously. We are currently unable to estimate the range of loss, if any, that we would incur if Petrobras is ultimately assessed such taxes and if it is determined that Petrobras is entitled to obtain reimbursement from us. If Petrobras is assessed such taxes and we are ultimately required to pay such reimbursement, the amount of such reimbursement could be substantial and could have a material adverse effect on our financial condition, results of operations and cash flows. NPI Arrangement. We received customer payments measured by a percentage net profits interest (primarily of 27%) under an overriding royalty interest in certain developmental oil-and-gas producing properties, or NPI, which we believe is a real property interest. Our drilling program related to the NPI was completed in 2011, and the balance of the amounts 5 8 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) due to us under the NPI was received in 2013. However, the customer who conveyed the NPI to us filed a voluntary petition for reorganization under Chapter 11 of the Bankruptcy Code in August 2012. Certain parties (including the debtor) in the bankruptcy proceedings questioned whether our NPI, and certain amounts we received under it since the filing of the bankruptcy, should be included in the debtor’s estate under the bankruptcy proceeding. In 2013, we filed a declaratory judgment action in the bankruptcy court seeking a declaration that our NPI, and payments that we received from it since the filing of the bankruptcy, are not part of the bankruptcy estate. We agreed to a settlement with the company that purchased most of the debtor’s assets (including the debtor’s claims against our NPI) whereby the nature of our NPI will not be challenged by that party and our declaratory judgment action was dismissed. Several lienholders filed motions in the bankruptcy contending that their liens have priority and seeking disgorgement of payments made to us after the bankruptcy was filed. We believe that the payments at issue are superior to these liens and expect the bankruptcy proceedings to be concluded with no further impact to us. Personal Injury Claims. Under our current insurance policies that expire on May 1, 2015, our deductibles for marine liability insurance coverage, including personal injury claims, which primarily result from Jones Act liability in the Gulf of Mexico, are $25.0 million for the first occurrence, with no aggregate deductible, and vary in amounts ranging between $5.0 million and, if aggregate claims exceed certain thresholds, up to $100.0 million for each subsequent occurrence, depending on the nature, severity and frequency of claims that might arise during the policy year. The Jones Act is a federal law that permits seamen to seek compensation for certain injuries during the course of their employment on a vessel and governs the liability of vessel operators and marine employers for the work-related injury or death of an employee. We engage outside consultants to assist us in estimating our aggregate liability for personal injury claims based on our historical losses and utilizing various actuarial models. We allocate a portion of the aggregate liability to “Accrued liabilities” based on an estimate of claims expected to be paid within the next twelve months with the residual recorded as “Other liabilities.” At December 31, 2014, our estimated liability for personal injury claims was $39.4 million, of which $8.2 million and $31.2 million were recorded in “Accrued liabilities” and “Other liabilities,” respectively, in our Consolidated Balance Sheets. At December 31, 2013, our estimated liability for personal injury claims was $35.5 million, of which $9.5 million and $26.0 million were recorded in “Accrued liabilities” and “Other liabilities,” respectively, in our Consolidated Balance Sheets. The eventual settlement or adjudication of these claims could differ materially from our estimated amounts due to uncertainties such as: (cid:129) the severity of personal injuries claimed; (cid:129) significant changes in the volume of personal injury claims; (cid:129) the unpredictability of legal jurisdictions where the claims will ultimately be litigated; (cid:129) inconsistent court decisions; and (cid:129) the risks and lack of predictability inherent in personal injury litigation. Purchase Obligations. Ultra-Deepwater Floater Construction. The Ocean GreatWhite, a 10,000 foot dynamically positioned, harsh environment semisubmersible drilling rig, is under construction in South Korea at an estimated cost of $764 million, including shipyard costs, customer-requested equipment, capital spares, commissioning, project management and shipyard supervision. The contracted price to Hyundai Heavy Industries Co., Ltd., or Hyundai, totaling $628.5 million is 8 6 2 0 1 4 A N N U A L R E P O R T I D A M O N D O F F S H O R E DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) payable in two installments, of which the first installment of $188.6 million has been paid. The final installment of $439.9 million is due upon delivery of the rig, which is expected to occur in the first quarter of 2016. Drillship Construction. At December 31, 2014, we had one remaining ultra-deepwater drillship, the Ocean BlackLion, under construction by Hyundai for an estimated cost of $655 million, including shipyard costs, commissioning, capital spares and project management costs. The contracted price of the drillship is payable to Hyundai in two installments, with final payment due on delivery of the drillship. We have paid the first installment of $169.3 million. We expect the Ocean BlackLion to be delivered in the first quarter of 2015, at which time approximately $395 million will be payable to Hyundai. At December 31, 2014 and 2013, we had no other purchase obligations for major rig upgrades or any other significant obligations, except for those related to our direct rig operations, which arise during the normal course of business. Operating Leases. We lease office and yard facilities, housing, equipment and vehicles under operating leases, which expire at various times through the year 2018. Total rent expense amounted to $10.6 million, $13.5 million and $10.8 million for the years ended December 31, 2014, 2013 and 2012, respectively. Future minimum rental payments under leases are approximately $1.3 million and $1.1 million for the years 2015 and 2016, respectively, and $1.2 million in the aggregate for the years 2017 to 2018. There are no minimum future rental payments under operating leases after 2018. Letters of Credit and Other. We were contingently liable as of December 31, 2014 in the amount of $99.6 million under certain performance, bid, supersedeas and custom bonds and letters of credit. Agreements relating to approximately $92.0 million of performance, security, supersedeas and customs bonds can require collateral at any time. As of December 31, 2014, we had not been required to make any collateral deposits with respect to these agreements. The remaining agreements cannot require collateral except in events of default. On our behalf, banks have issued letters of credit securing certain of these bonds. 1 3 . R e l a t e d - P a r t y T r a n s a c t i o n s Transactions with Loews. We are party to a services agreement with Loews, or the Services Agreement, pursuant to which Loews performs certain administrative and technical services on our behalf. Such services include personnel, internal auditing, accounting, and cash management services, in addition to advice and assistance with respect to preparation of tax returns and obtaining insurance. Under the Services Agreement, we are required to reimburse Loews for (i) allocated personnel costs (such as salaries, employee benefits and payroll taxes) of the Loews personnel actually providing such services and (ii) all out-of-pocket expenses related to the provision of such services. The Services Agreement may be terminated at our option upon 30 days’ notice to Loews and at the option of Loews upon six months’ notice to us. In addition, we have agreed to indemnify Loews for all claims and damages arising from the provision of services by Loews under the Services Agreement unless due to the gross negligence or willful misconduct of Loews. We were charged $1.1 million, $1.0 million and $0.8 million by Loews for these support functions during the years ended December 31, 2014, 2013 and 2012, respectively. Transactions with Other Related Parties. We hire marine vessels and helicopter transportation services at the prevailing market rate from subsidiaries of SEACOR Holdings Inc. and Era Group Inc. The Executive Chairman of the Board of Directors of SEACOR Holdings Inc. and the Non-Executive Chairman of the Board of Directors of Era Group Inc. is also a member of our Board of Directors. We paid $0.8 million, $0.1 million and $0.1 million for the hire of such vessels and such services during the years ended December 31, 2014, 2013 and 2012, respectively. 7 8 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The wife of our former President and Chief Executive Officer was an audit partner at Ernst & Young LLP, or E&Y, during his term of service with us. For the year ended December 31, 2014, we made payments aggregating $2.9 million to E&Y for tax and other consulting services; however, E&Y ceased to be a related party on March 3, 2014. For the years ended December 31, 2013 and 2012, we made payments to E&Y of $1.6 million and $1.0 million, respectively. 1 4 . In c o m e Ta x e s Our income tax expense is a function of the mix between our domestic and international pre-tax earnings or losses, as well as the mix of international tax jurisdictions in which we operate. Certain of our international rigs are owned and operated indirectly by Diamond Offshore International Limited, or DOIL, a foreign subsidiary which we wholly own. It is our intention to indefinitely reinvest future earnings of DOIL and its foreign subsidiaries to finance foreign activities. Accordingly, we have not made a provision for U.S. income taxes on approximately $2.4 billion of undistributed foreign earnings and profits. Although we do not intend to repatriate the earnings of DOIL, and have not provided U.S. income taxes for such earnings, except to the extent that such earnings were immediately subject to U.S. income taxes, these earnings could become subject to U.S. income tax if remitted, or if deemed remitted as a dividend; however, it is not practical to estimate this potential liability. The components of income tax expense (benefit) are as follows: Year Ended December 31, 2014 2013 2012 (In thousands) Federal — current . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 66,843 $ 40,045 $173,061 State — current . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Foreign Tax Credits. As of December 31, 2014, we had recorded a deferred tax asset of $17.5 million for the benefit of foreign tax credits in the U.S. and a $0.5 million deferred tax asset for the benefit of foreign tax credits in the United Kingdom, or U.K. Our excess foreign tax credits in the U.S. will be carried back to 2013 but otherwise will expire in 2024. Our U.K. foreign tax credits, for which we recorded a valuation allowance, may be carried forward indefinitely. Other Deferred Tax Assets. As of December 31, 2014, we had recorded a deferred tax asset of $21.9 million for the benefit of disallowed bareboat charter deductions in the U.K. for which we recorded a valuation allowance and a deferred tax asset of $5.3 million for foreign contribution taxes in Brazil for which we also recorded a valuation reserve. 1 9 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC.

In most cases, there are alternative transfer pricing methodologies that could be applied to these transactions and, if applied, could result in different chargeable amounts.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) locations in which we operate could apply one of the alternative transfer pricing methodologies which could result in an increase to our income tax liabilities with respect to tax returns that remain subject to examination. We expect the statute of limitations for the 2009 tax year to expire in 2015 for one of our Mexican entities, and we anticipate that the related unrecognized tax benefit will decrease by $10.7 million at that time. Tax Returns and Examinations. We file income tax returns in the U.S. federal jurisdiction, various state jurisdictions and various foreign jurisdictions. Tax years that remain subject to examination by these jurisdictions include years 2008 to 2014. We are currently under audit in several of these jurisdictions. We do not anticipate that any adjustments resulting from the tax audit of any of these years will have a material impact on our consolidated results of operations, financial condition or cash flows. Brazil Tax Jurisdiction. In December 2009, we received an assessment of approximately $26.0 million for the years 2004 and 2005, including interest and penalty. We contested the tax assessment in 2010 and, during the third quarter of 2014, received a favorable court decision resulting in the closure of the 2004 and 2005 tax years. As a consequence, we reversed our $14.0 million reserve for this uncertain tax position, of which $3.5 million was interest and $4.4 million was penalty. In March 2013, the Brazilian tax authorities began an audit of our income tax returns for the years 2009 and 2010. In February 2012, the tax authorities concluded their audit of our income tax return for the 2007 tax year for which we received an assessment of R$35.1 million (approximately equal to USD $13 million at December 31, 2014) for income tax, including interest and penalties. We contested the assessment and a court in Brazil ruled to cancel the assessment. However, the Brazilian tax authorities have appealed the ruling, and we are awaiting the outcome of the appeal. We have not accrued any tax expense related to this assessment. In addition, the tax auditors have issued an assessment for tax year 2000 of approximately $1.5 million, including interest and penalty. We have appealed the tax assessment and are awaiting the outcome of the appeal. Egypt Tax Jurisdiction. During 2013, we were under audit by the Egyptian tax authorities for the tax years 2006 through 2010. In 2013, after receiving notification that the Egyptian government had concluded the income tax audit for the period 2006 to 2008 and proposed a $1.2 billion increase to taxable income, we accrued an additional $56.9 million of expense for uncertain tax positions in Egypt for all open years. During the first quarter of 2014, we settled certain disputes for the years 2006 through 2008 with the Egyptian tax authorities, which resulted in an aggregate $17.2 million reduction in tax expense, comprised of a $23.2 million reversal of uncertain tax positions, partially offset by $6.0 million in current foreign income tax expense. One issue for the 2006 through 2008 period remains open, which we appealed. During the second quarter of 2014, the Appeals Committee in Egypt issued a decision regarding this open item, with which we disagree. We have filed an objection with the Egyptian courts and continue to dispute the matter. We have also sought assistance from an agency of the U.S. Treasury Department, pursuant to international tax treaties, and continue to believe that our position will, more likely than not, be sustained. However, if our position is not sustained, tax expense and related penalties would increase by approximately $50 million related to this issue for the 2006 through 2008 tax years as of December 31, 2014. Malaysia Tax Jurisdiction. During the third quarter of 2014, we received final approval from the Malaysian tax authorities for the settlement of tax liabilities and penalties for the years 2003 through 2008 resulting in the reversal of a $14.2 million reserve for uncertain tax positions for these years, of which $5.3 million was penalty. 3 9 T R O P E R L A U N N A 4 1 0 2 E R O H S F F O D N O M A D I DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Mexico Tax Jurisdiction. Due to the 2014 expiration of the statute of limitations in Mexico for the 2008 tax year for one of our subsidiaries operating in Mexico, we reversed our $8.0 million accrual for an uncertain tax position, of which $2.7 million was interest and $1.1 million was penalty, during the year ended December 31, 2014. However, the 2008 income tax return of one of our other Mexican subsidiaries is under audit by the Mexican tax authorities. The tax authorities in Mexico previously audited our income tax returns for the years 2004 and 2006 and had issued assessments for tax years 2004 and 2006 of approximately $22.9 million and $24.4 million, respectively, including interest and penalties, which we had appealed. In 2013 the Mexican tax authorities initiated a tax amnesty program whereby income tax assessments, including penalties and interest, could be partially or completely waived. Under the tax amnesty, we were able to settle our tax liabilities for the years 2004 and 2006 for a net cash cost of $3.7 million. As a result of increases in uncertain tax positions for later years, we recorded an additional $13.2 million of expense, including $5.0 million of interest and $2.7 million of penalties, during the year ended December 31, 2013. Due to the expiration of the statute of limitations in Mexico for the 2007 tax year at the end of June 2013, during the second quarter of 2013, we reversed our $4.3 million accrual for this uncertain tax position, of which $1.5 million was interest and $0.6 million was penalty. In addition, in August 2012, the Mexican tax authorities dismissed a claim against one of our Mexican subsidiaries and the 2004 tax year for that subsidiary is now closed. Consequently, during the third quarter of 2012, we reversed our $4.4 million accrual for this uncertain tax position, which included $0.2 million of penalty and $2.6 million of interest. United Kingdom Tax Jurisdiction. The U.K. Finance Act of 2014, or the Finance Act, was enacted in July 2014 with an effective date retroactive to April 1, 2014. Certain provisions of the Finance Act will limit the amount of tax deductions available with respect to our rigs working in the U.K. under bareboat charter arrangements, which has caused our expected tax expense for the full year of 2014 to increase by approximately $22 million. American Taxpayer Relief Act of 2012. The American Taxpayer Relief Act of 2012, or the Act, was signed into law on January 2, 2013. The Act extended through 2013 several expired or expiring temporary business provisions, commonly referred to as “extenders,” which were retroactively extended to the beginning of 2012. As required by GAAP, the effects of new legislation are recognized when signed into law. Consequently, we reduced our 2013 tax expense by $27.5 million as a result of recognizing the 2012 effect of the extenders. 15. E mp l oy ee B e nefi t Plans Defined Contribution Plans We maintain defined contribution retirement plans for our U.S., U.K. and third-country national, or TCN, employees. The plan for our U.S. employees, or the 401k Plan, is designed to qualify under Section 401(k) of the Internal Revenue Code of 1986, as amended, or the Code. Under the 401k Plan, each participant may elect to defer taxation on a portion of his or her eligible earnings, as defined by the 401k Plan, by directing his or her employer to withhold a percentage of such earnings. A participating employee may also elect to make after-tax contributions to the 401k Plan. During each of the years ended December 31, 2014, 2013 and 2012, we made a 4% profit-share contribution of participants’ defined compensation and matched up to 6% of each employee’s compensation contributed to the 401k Plan. Participants are fully vested in the employer match immediately upon enrollment in the 401k Plan and subject to a three-year cliff vesting period for the profit sharing contribution.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure. Not applicable. Item 9A. Controls and Procedures Disclosure Controls and Procedures We maintain a system of disclosure controls and procedures which are designed to ensure that information required to be disclosed by us in reports that we file or submit under the federal securities laws, including this report, is recorded, processed, summarized and reported on a timely basis. These disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by us under the federal securities laws is accumulated and communicated to our management on a timely basis to allow decisions regarding required disclosure. Our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, participated in an evaluation by our management of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of December 31, 2014. Based on their participation in that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of December 31, 2014. Internal Control Over Financial Reporting Management’s Annual Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for Diamond Offshore Drilling, Inc. Our internal control system was designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements. There are inherent limitations to the effectiveness of any control system, however well designed, including the possibility of human error and the possible circumvention or overriding of controls. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Management must make judgments with respect to the relative cost and expected benefits of any specific control measure. The design of a control system also is based in part upon assumptions and judgments made by management about the likelihood of future events, and there can be no assurance that a control will be effective under all potential future conditions. As a result, even an effective system of internal controls can provide no more than reasonable assurance with respect to the fair presentation of financial statements and the processes under which they were prepared. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2014. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Based on this assessment our management believes that, as of December 31, 2014, our internal control over financial reporting was effective. Deloitte & Touche LLP, the registered public accounting firm that audited our financial statements included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of our internal control over financial reporting. The attestation report of Deloitte & Touche LLP is included at the beginning of Item 8 of this Form 10-K. Changes in Internal Control Over Financial Reporting There were no changes in our internal control over financial reporting identified in connection with the foregoing evaluation that occurred during our fourth fiscal quarter of 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
