NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

NOTE 1—BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

McDermott International, Inc. (“MII”), a corporation incorporated under the laws of the Republic of Panama in 1959, is a leading engineering, procurement, construction and installation (“EPCI”) company focused on designing and executing complex offshore oil and gas projects worldwide. Providing fully integrated EPCI services, we deliver fixed and floating production facilities, pipeline installations and subsea systems from concept to commissioning. Operating in approximately 20 countries across the Americas, Middle East, Asia Pacific, the North Sea and Africa, our integrated resources include approximately 14,000 employees and a diversified fleet of marine vessels, fabrication facilities and engineering offices. We support our activities with comprehensive project management and procurement services, while utilizing our fully integrated capabilities in both shallow water and deepwater construction. Our customers include national, major integrated and other oil and gas companies, and we operate in most major offshore oil and gas producing regions throughout the world. We execute our contracts through a variety of methods, principally fixed-price, but also including cost reimbursable, cost-plus, day-rate and unit-rate basis or some combination of those methods. In these notes to our unaudited condensed consolidated financial statements, unless the context otherwise indicates, “we,” “us” and “our” mean MII and its consolidated subsidiaries.

Basis of Presentation

We have presented our unaudited condensed consolidated financial statements in U.S. Dollars, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim reporting. Financial information and disclosures normally included in our financial statements prepared annually in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted. Readers of these financial statements should, therefore, refer to the consolidated financial statements and the accompanying notes in our annual report on Form 10-K for the year ended December 31, 2013.

We have included all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation. These condensed consolidated financial statements include the accounts of McDermott International, Inc., its consolidated subsidiaries and controlled entities. We use the equity method to account for investments in entities that we do not control, but over which we have significant influence. We generally refer to these entities as “unconsolidated affiliates” or “joint ventures.” We have eliminated all intercompany transactions and accounts.

Certain 2013 amounts in the condensed consolidated balance sheet and statement of cash flows, reflecting the non cash impacts on gain of foreign exchange, have been reclassified to conform to the 2014 presentation.

Business Segments

In March 2014, we changed our organizational structure to orient around our offshore and subsea business activities through four primary geographic regions. The four geographic regions, which we consider to be our operating segments, consist of Asia Pacific, Americas (previously Atlantic), Middle East and North Sea and Africa. The Caspian is no longer considered an operating segment and will continue to be aggregated in the Middle East reporting segment. The North Sea and Africa operating segment is also aggregated into the Middle East reporting segment due to the proximity of regions and similarities in the nature of services provided, economic characteristics and oversight responsibilities. Accordingly, we continue to report financial results under reporting segments consisting of Asia Pacific, Americas and the Middle East. We also report certain corporate and other non-operating activities under the heading “Corporate and other,” which primarily reflects corporate personnel and activities, incentive compensation programs and other costs that are generally fully allocated to our operating segments. The only corporate costs not allocated to our operating segments are the restructuring costs associated with our corporate reorganization. See Note 9 for summarized financial information on our segments.

Revenue Recognition

We determine the appropriate accounting method for each of our long-term contracts before work on the project begins. We generally recognize contract revenues and related costs on a percentage-of-completion method for individual contracts or combinations of contracts based on work performed, man hours, or a cost-to-cost method, as applicable to the activity involved. We include the amount of accumulated contract costs and estimated earnings that exceed billings to customers in contracts in progress. We include billings to customers that exceed accumulated contract costs and estimated earnings in advance billings on contracts. Most long-term contracts contain provisions for progress payments. We expect to invoice customers for and collect all unbilled revenues. Certain costs are generally excluded from the cost-to-cost method of measuring progress, such as significant procurement costs for materials and

8

third-party subcontractors. Total estimated project costs, and resulting income, are affected by changes in the expected cost of materials and labor, productivity, vessel costs, scheduling and other factors. Additionally, external factors such as weather, customer requirements and other factors outside of our control may affect the progress and estimated cost of a project’s completion and, therefore, the timing and amount of revenue and income recognition.

In addition, change orders, which are a normal and recurring part of our business, can increase (sometimes substantially) the future scope and cost of a job. Therefore, change order awards (although frequently beneficial in the long term) can have the short-term effect of reducing the job percentage of completion and thus the revenues and profits recognized to date. We regularly review contract price and cost estimates as the work progresses and reflect adjustments in profit, proportionate to the job percentage of completion in the period when those estimates are revised. Revenue from unapproved change orders is generally recognized to the extent of the lesser of amounts we expect to recover or costs incurred. Additionally, to the extent that claims included in backlog, including those that arise from change orders which are under dispute or which have been previously rejected by the customer, are not resolved in our favor, there could be reductions in or reversals of previously reported revenues and profits, and charges against current earnings, which could be material. Unapproved change orders that are disputed by the customer are treated as claims.

As of June 30, 2014, total unapproved change orders included in our estimates at completion aggregated approximately $297.0 million, of which approximately $44.0 million was included in backlog. As of June 30, 2013, total unapproved change orders included in our estimates at completion aggregated approximately $445.0 million, of which approximately $170.0 million was included in backlog.

Claims Revenue

Claims revenue may relate to various factors, including the procurement of materials, equipment performance failures, change order disputes or schedule disruptions and other delays, including those associated with weather or sea conditions. Claims revenue, when recorded, is only recorded to the extent of the lesser of the amounts we expect to recover or the associated costs incurred in our consolidated financial statements. We include certain unapproved claims in the applicable contract values when we have a legal basis to do so, consider collection to be probable and believe we can reliably estimate the ultimate value. Amounts attributable to unapproved change orders are not included in claims unless and until they are disputed by the customer. We continue to actively engage in negotiations with our customers on our outstanding claims. However, these claims may be resolved at amounts that differ from our current estimates, which could result in increases or decreases in future estimated contract profits or losses. Claims are generally negotiated over the course of the respective projects and many of our projects are long-term in nature. None of the pending claims as of June 30, 2014 were the subject of any litigation proceedings.

The amount of revenues and costs included in our estimates at completion (i.e., contract values) associated with such claims was $6.5 million and $173.4 million as of June 30, 2014 and June 30, 2013, respectively. All of these claim amounts at June 30, 2014 were related to our Middle East segment. Approximately 44%, 10% and 46% of these claim amounts as of June 30, 2013 were related to our Asia Pacific, Americas and Middle East segments, respectively. For the three- and six-month periods ended June 30, 2014, no revenues or costs pertaining to claims were included in our condensed consolidated financial statements. For the three- and six-month periods ended June 30, 2013, $11.0 million and $39.4 million of revenues and costs pertaining to claims were included in our condensed consolidated financial statements, respectively.

Our unconsolidated joint ventures did not include any claims revenue or associated cost in their financial results for the three- and six-month period ended June 30, 2014. For the three- and six-month periods ended June 30, 2013, our unconsolidated joint ventures included nil and $3.7 million, respectively, of claims and associated costs in their financial results.

Deferred Profit Recognition

For contracts as to which we are unable to estimate the final profitability due to their uncommon nature, including first-of-a-kind projects, we recognize equal amounts of revenue and cost until the final results can be estimated more precisely. For these contracts, we only recognize gross margin when reliably estimable and the level of uncertainty has been significantly reduced, which we generally determine to be when the contract is at least 70% complete. We treat long-term construction contracts that contain such a level of risk and uncertainty that estimation of the final outcome is impractical as deferred profit recognition contracts. If, while being accounted for under our deferred profit recognition policy, a current estimate of total contract costs indicates a loss, the projected loss is recognized in full and the project is accounted for under our normal revenue recognition guidelines. At June 30, 2014, no projects were accounted for under our deferred profit recognition policy.

Completed Contract Method

Under the completed contract method, revenue and gross profit is recognized only when a contract is completed or substantially complete. We generally do not enter into fixed-price contracts without an estimate of cost to complete that we believe to be reasonable. However, it is possible that in the time between contract execution and the start of work on a project, we could lose the ability to forecast cost to complete based on intervening events, including, but not limited to, experience on similar projects, civil unrest, strikes and volatility in our expected costs. In such a situation, we would use the completed contract method of accounting for that project. We did not enter into any contracts that we accounted for under the completed contract method during the quarters ended June 30, 2014 and June 30, 2013.

Loss Recognition

A risk associated with fixed-priced contracts is that revenue from customers may not cover increases in our costs. It is possible that current estimates could materially change for various reasons, including, but not limited to, fluctuations in forecasted labor and vessel productivity, vessel repair requirements, weather downtime, subcontractor or supplier performance, pipeline lay rates or steel and other raw material prices. Increases in costs associated with our fixed-price contracts could have a material adverse impact on our consolidated financial condition, results of operations and cash flows. Alternatively, reductions in overall contract costs at completion could materially improve our consolidated financial condition, results of operations and cash flows.

As of June 30, 2014, we have provided for our estimated costs to complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results for any fiscal quarter or year. For all contracts, if a current estimate of total contract cost indicates a loss, the projected loss is recognized in full when determined.

Of the June 30, 2014 backlog, approximately $426.4 million relates to four active projects that are in loss positions, whereby future revenues are expected to equal costs when recognized. Included in this amount is $169.7 million of backlog associated with an EPCI project in Altamira, which is expected to be completed in the fourth quarter of 2015, $133.0 million pertaining to a five-year charter of the Agile in Brazil, which began in early 2012, and $33.1 million relating to a subsea project in the U.S. Gulf of Mexico scheduled for completion during 2014, all of which are being conducted by our Americas segment. The amount also includes $90.6 million of backlog relating to an EPCI project in Saudi Arabia, in our Middle East segment, which is expected to be completed by early 2016. These four projects represent approximately 100% of the backlog amount in a loss position. It is possible that our estimates of gross profit could increase or decrease based on changes in productivity, actual downtime and the resolution of change orders and claims with the customers.

Use of Estimates

We use estimates and assumptions to prepare our financial statements in conformity with GAAP. These estimates and assumptions affect the amounts we report in our financial statements and accompanying notes. Our actual results could differ from these estimates, and variances could materially affect our financial condition and results of operations in future periods. Changes in project estimates generally exclude change orders and changes in scope, but may include, without limitation, unexpected changes in weather conditions, productivity, unanticipated vessel repair requirements, customer, subcontractor and supplier delays and other costs. We generally expect to experience a reasonable amount of unanticipated events, and some of these events can result in significant cost increases above cost amounts we previously estimated. As of June 30, 2014, we have provided for our estimated costs to complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results.

The following is a discussion of our most significant changes in estimates that impacted operating income for the three months and six months ended June 30, 2014 and 2013.

Three months ended June 30, 2014

Operating income for the three months ended June 30, 2014 was impacted by changes in cost estimates relating to projects in each of our segments.

The Asia Pacific segment was positively impacted by net favorable changes in/variances from estimates aggregating approximately $15.8 million, mostly due to reduced cost estimates on a subsea project in Malaysia, which was completed earlier in 2014, of approximately $10.2 million during the three months ended June 30, 2014. Those reduced cost estimates were primarily related to project close-out savings on marine spread and procurement costs. In addition, completion of three smaller projects resulted in project close-out savings of approximately $5.6 million.

10

The Middle East segment experienced net favorable changes in estimates aggregating approximately $22.0 million, primarily due to increased cost recovery estimates of approximately $29.2 million on a pipelay project in the Caspian, which was completed earlier in 2014. The increased cost recovery estimates were based on positive developments during the three months ended June 30, 2014 from the ongoing project close-out process with the customer. This improvement was partially offset by $7.2 million of increased estimated costs to complete an EPCI project in Saudi Arabia, mainly for the onshore scope on the project.

The Americas segment deteriorated by a net $13.4 million from changes in estimates on three projects. On an EPCI project in Altamira, we increased our estimated costs to complete by approximately $20.0 million, primarily due to projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On a subsea project in the US Gulf of Mexico, we increased our estimated costs to complete by approximately $23.3 million, primarily due to equipment downtime issues on the North Ocean 102 (the “NO 102”), our primary vessel working on the project. This project is in a loss position and is estimated to be completed in the third quarter of 2014. These negative impacts were partly offset by approximately $30.0 million of project close-out improvements on an EPCI project in Brazil, which was completed earlier in 2014, from marine cost reductions and increased recoveries due to successful developments from ongoing approval process for additional weather-related compensation.

Six months ended June 30, 2014

Operating income for the six months ended June 30, 2014 was impacted by changes in cost estimates relating to projects in each of our segments.

The Asia Pacific segment experienced net favorable changes in estimates aggregating approximately $30.8 million, mostly due to changes in estimates on a subsea project in Malaysia during the six months ended June 30, 2014. Those changes were primarily related to productivity improvements on our marine vessels and offshore support activities, as well as project close-out savings.

The Middle East segment was negatively impacted by net unfavorable changes aggregating approximately $12.7 million, due to changes in five projects in the region. On three EPCI projects in Saudi Arabia, we increased our estimated cost at completion by approximately $35.3 million, primarily as a result of vessel downtime due to weather and standby delays (which may be recoverable from the customer, but which were not recognizable at June 30, 2014), reduced productivity levels and increased cost estimates to complete the onshore scope of one of the projects. On an EPCI project in Saudi Arabia, we increased our overall estimated costs to complete by approximately $6.6 million of cost overruns related to (1) the onshore work which was substantially completed in July 2014, and (2) delays in completing the offshore work, due to limited access to the project site, which is caused by schedule conflicts with another contractor. These negative changes were partly offset by approximately $29.1 million of increased cost recovery estimates on a pipelay project in the Caspian, based on positive developments during the three months ended June 30, 2014 from the ongoing project close-out process with the customer.

The Americas segment was negatively impacted by net unfavorable changes in estimates aggregating approximately $39.3 million associated with four projects. On an EPCI project in Altamira, we increased our estimated costs to complete by approximately $55.4 million, due to liquidated damages and extended project management costs arising from expected project delays, projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On a subsea project in the US Gulf of Mexico, we increased our estimated costs to complete by approximately $22.5 million, primarily due to equipment downtime issues on the NO 102, our primary vessel working on the project. This project is in a loss position and is estimated to be completed in the third quarter of 2014. These negative impacts were partly offset by $33.7 million of project close out improvements on an EPCI project in Brazil from marine cost reductions upon completion of activities and increased recoveries due to successful developments from ongoing approval process for additional weather related compensation. We also recognized $4.9 million cost reductions, mainly due to project close-out improvements, on a marine installation project in the US Gulf of Mexico.

Three months ended June 30, 2013

The Asia Pacific segment was primarily impacted by changes in estimates on one subsea project in Malaysia. On that project, we increased our estimated cost at completion by approximately $62.0 million in the three months ended June 30, 2013, primarily due to delays resulting from direct and indirect impacts of equipment modification problems during the final commissioning stage of a major pipe-lay systems upgrade to the North Ocean 105 (the “NO 105”), which was required to execute the project scope. As a result of these delays the as-bid project execution plan was no longer achievable. As a result, the revised project execution plan required a split marine campaign in order to avoid working in adverse weather periods. Mechanical downtime of a third-party support vessel also contributed to project delays. In consideration of these factors, the expected completion date for the project was extended from the fourth quarter 2013 to the middle of 2014. In addition, the extended schedule resulted in forecasted liquidated damages under the contract terms with the customer. This project was completed during the three months ended June 30, 2014.

11

The Middle East segment was impacted by changes in estimates on one of our EPCI projects in Saudi Arabia. On that project, we increased our estimated cost at completion by approximately $38.0 million in the three months ended June 30, 2013, primarily as a result of revisions to the project’s execution plan, increases in our estimated cost to complete due to an extended offshore hookup campaign requiring multiple vessel mobilizations and, to a lesser extent, delays in the completion of onshore activities. While the project recognized losses in the three months ended June 30, 2013, it remains in an overall profitable position.

The Americas segment was impacted by changes in estimates on two projects. On one of those projects, we recognized approximately $7.0 million of incremental project losses in the three months ended June 30, 2013, primarily due to lower than expected labor productivity on a fabrication project in Morgan City. This project was completed during the year ended December 31, 2013. We also recognized project losses of approximately $3.0 million in the three months ended June 30, 2013 on another fabrication project in Morgan City, which was completed during the quarter ended June 30, 2013.

Six months ended June 30, 2013

The Asia Pacific segment was primarily impacted by changes in estimates on three projects. On one project (the project in Malaysia described above), we increased our estimated cost at completion by approximately $66.0 million in the six months ended June 30, 2013, primarily due to delays resulting from direct and indirect impacts of the equipment modification problems during the final commissioning stage of the major pipe-lay systems upgrade to the NO 105 and the other factors described above. We also benefited from reduced estimated costs during contract close-out of approximately $14 million during the three-month period ended March 31, 2013, primarily due to efficiencies associated with marine campaigns on two our EPCI projects, both of which were completed in the six-month period ended June 30, 2013.

The Middle East segment was impacted by changes in estimates on the EPCI project in Saudi Arabia discussed above. On that project, we increased our estimated cost at completion by approximately $43.0 million in the six months ended June 30, 2013, primarily as a result of revisions to the project’s execution plan, increases in our estimated cost to complete due to an extended offshore hookup campaign requiring multiple vessel mobilizations and, to a lesser extent, delays in the completion of onshore activities. While the project recognized losses in the three months ended June 30, 2013, it remains in an overall profitable position.

The Americas segment was impacted by changes in estimates on one fabrication project in Morgan City. On that project, we recognized approximately $14.0 million of incremental project losses in the six months ended June 30, 2013, primarily due to lower than expected labor productivity. This project was completed during the year ended December 31, 2013.

Loss Contingencies

We record liabilities for loss contingencies when it is probable that a liability has been incurred and the amount of loss is reasonably estimable. We provide disclosure when there is a reasonable possibility that the ultimate loss will exceed the recorded provision or if such loss is not reasonably estimable. We are currently involved in litigation and other proceedings, as discussed in Note 10. We have accrued our estimates of the probable losses associated with these matters, and associated legal costs are generally recognized in selling, general and administrative expenses as incurred. However, our losses are typically resolved over long periods of time and are often difficult to estimate due to various factors, including the possibility of multiple actions by third parties. Therefore, it is possible future earnings could be affected by changes in our estimates related to these matters.

Cash and Cash Equivalents

Our cash and cash equivalents are highly liquid investments with maturities of three months or less when we purchase them. We record cash and cash equivalents as restricted when we are unable to freely use such cash and cash equivalents for our general operating purposes. A majority of our restricted cash and cash equivalents represents collateralizing letters of credit as further discussed in Note 3.

Investments

We classify investments available for current operations as current assets in the accompanying balance sheets, and we classify investments held for long-term purposes as noncurrent assets. We adjust the amortized cost of debt securities for amortization of premiums and accretion of discounts to maturity. That amortization is included in interest income. We include realized gains and losses on our investments in other income (expense)—net. The cost of securities sold is based on the specific identification method. We include interest earned on securities in interest income.

12

Investments in Unconsolidated Affiliates

We generally use the equity method of accounting for affiliates in which our investment ownership ranges from 20% to 50%, and in which we do not exercise control over the entity. Currently, most of our investments in affiliates that are not consolidated are recorded using the equity method.

Accounts Receivable

Accounts Receivable—Trade, Net

A summary of contract receivables is as follows:

	June 30, 2014			December 31, 2013
	(In thousands)
Contract receivables:
Contracts in progress	$	121,920		$	192,745
Completed contracts		42,743			77,248
Retainages		85,587			127,698

Less allowances		(29,094	)		(30,404	)
Accounts receivable—trade, net	$	225,459		$	381,858

We expect to invoice our unbilled receivables once certain milestones or other metrics are reached, and we expect to collect all unbilled amounts. We believe that our provision for losses on uncollectible accounts receivable is adequate for our credit loss exposure.

Contract retainages generally represent amounts withheld by our customers until project completion, in accordance with the terms of the applicable contracts. The following is a summary of retainages on our contracts:

	June 30, 2014		December 31, 2013
	(In thousands)
Retainages expected to be collected within one year	$	85,587	$	127,698
Retainages expected to be collected after one year		145,883		65,365
Total retainages	$	231,470	$	193,063

We have included in accounts receivable—trade, net, retainages expected to be collected within one year.

Accounts Receivable—Other

A summary of accounts receivable— other is as follows:

	June 30, 2014		December 31, 2013
	(In thousands)
Receivables from unconsolidated affiliates	$	18,207	$	36,181
Other taxes receivable		23,678		14,934
Accrued unbilled revenue		13,219		15,696
Asset derivatives		5,055		11,641
Employee receivables		3,973		4,532
Other		8,215		6,289
Accounts receivables – other	$	72,347	$	89,273

13

Employee receivables are expected to be collected within 12 months, and any allowance for doubtful accounts on our accounts receivable—other is based on our estimate of the amount of probable losses due to the inability to collect these amounts (based on historical collection experience and other available information). As of June 30, 2014 and December 31, 2013, no such allowance for doubtful accounts was recorded.

Contracts in Progress and Advance Billings on Contracts

Contracts in progress were $440.3 million and $426.0 million at June 30, 2014 and December 31, 2013, respectively. Advance billings on contracts were $204.5 million at June 30, 2014 and $278.9 million at December 31, 2013. A detail of the components of contracts in progress and advance billings on contracts is as follows:

	June 30, 2014		December 31, 2013
	(In thousands)
Costs incurred less costs of revenue recognized	$	94,167	$	65,113

Other Non-Current Assets

We have included debt issuance costs in other assets. We amortize debt issuance costs as interest expense on a straight-line basis over the life of the related debt. The following summarizes the changes in the carrying amount of these assets:

	Six months ended June 30, 2014			Year ended December 31, 2013
	(In thousands)
Balance at beginning of period	$	14,951		$	13,761
Debt issuance costs		45,521			4,905

Amortization of interest expense		(4,315	)		(3,715	)
Balance at end of period	$	44,244		$	14,951

Also included in other non-current assets is long-term deferred drydock expenses, long-term prepaid rent and other prepaid expenses.

Fair Value of Financial Instruments

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 an orderly transaction between market participants at the measurement date. An established hierarchy for inputs is used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors that market participants would use in valuing the asset or liability.

14

Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

• Level 1—inputs are based upon quoted prices for identical instruments traded in active markets.

• Level 2—inputs are based upon quoted prices for similar instruments in active markets, quoted prices for similar or identical instruments in inactive markets and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets and liabilities.

• Level 3—inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar valuation techniques.

The carrying amounts that we have reported for financial instruments, including cash and cash equivalents, accounts receivables and accounts payable approximate their fair values. See Note 6 for additional information regarding fair value measurements.

Derivative Financial Instruments

Our worldwide operations give rise to exposure to changes in certain market conditions, which may adversely impact our financial performance. When we deem it appropriate, we use derivatives as a risk management tool to mitigate the potential impacts of certain market risks. The primary market risk we manage through the use of derivative instruments is movement in foreign currency exchange rates. We use foreign currency derivative contracts to reduce the impact of changes in foreign currency exchange rates on our operating results. We use these instruments to hedge our exposure associated with revenues and/or costs on our long-term contracts and other cash flow exposures that are denominated in currencies other than our operating entities’ functional currencies. We do not hold or issue financial instruments for trading or other speculative purposes.

In certain cases, contracts with our customers contain provisions under which some payments from our customers are denominated in U.S. Dollars and other payments are denominated in a foreign currency. In general, the payments denominated in a foreign currency are designed to compensate us for costs that we expect to incur in such foreign currency. In these cases, we may use derivative instruments to reduce the risks associated with foreign currency exchange rate fluctuations arising from differences in timing of our foreign currency cash inflows and outflows. See Note 5 for additional information regarding derivative financial instruments.

Foreign Currency Translation

We translate assets and liabilities of our foreign operations, other than operations in highly inflationary economies, into U.S. Dollars at period-end exchange rates, and we translate income statement items at average exchange rates for the periods presented. We record adjustments resulting from the translation of foreign currency financial statements as a component of accumulated other comprehensive income (loss) (“AOCI”), net of tax.

Earnings per Share

We have computed earnings per common share on the basis of the weighted average number of common shares, and, where dilutive, common share equivalents, outstanding during the indicated periods. See Note 8 for our earnings per share computations.

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. This ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. It also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 is effective for us for annual and interim reporting periods beginning after December 15, 2016, with early application not permitted. We have the choice to apply it either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying it at the date of initial application (January 1, 2017) and not adjusting comparative information. We are currently evaluating the requirements of this ASU and have not yet determined its impact on our consolidated financial statements.

In July 2013, FASB issued an update to the topic Income Taxes. The update clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if settlement is required or expected in the event the uncertain tax position is disallowed. In situations where these items are not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the applicable jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The update is effective for 2014, and the adoption of this update did not have a material impact on our condensed consolidated financial statements.

NOTE 2—ACQUISITION AND DISPOSITIONS

Acquisition

During the quarter ended March 31, 2013, we entered into a share purchase agreement to acquire all of the issued and outstanding shares of capital stock of Deepsea Group Limited, a United Kingdom-based company that provides subsea and other engineering services to international energy companies, primarily through offices in the United Kingdom and the United States. Total consideration was approximately $9.0 million, which includes cash ($6.0 million) and the delivery of 313,580 restricted shares of MII common stock (out of treasury). The transaction was accounted for using the acquisition method and, accordingly, assets acquired and liabilities assumed were recorded at their respective fair values.

During the quarter ended December 31, 2013, we entered into two joint ventures with TH Heavy Engineering Berhad (“THHE”), whereby we acquired a 30% interest in a subsidiary of THHE, THHE Fabricators Sdn. Bhd., and THHE acquired a 30% interest in our Malaysian subsidiary, Berlian McDermott Sdn. Bhd. Accounting for these transactions is preliminary at June 30, 2014 and is pending finalization of these transactions by the end of 2014. As of June 30, 2014, we recorded an equity method investment of approximately $25.5 million, a non-controlling interest of approximately $20.9 million and an increase in capital in excess of par value of approximately $4.6 million arising from these transactions.

Non-Core Asset Sales

We previously committed to a plan to sell four of our multi-function marine vessels, specifically the Bold Endurance, DB 16, DB 26 and the DLB KP1. Assets classified as held for sale are no longer depreciated. During the six months ended June 30, 2014, we completed the sale of the DLB KP1 for aggregate cash proceeds of approximately $8.4 million, resulting in a gain of approximately $6.4 million recognized in our Middle East segment. During the six months ended June 30, 2013 we completed the sale of the Bold Endurance and the DB 26 for aggregate cash proceeds of approximately $32.0 million, resulting in an aggregate gain of approximately $12.5 million. We remain in discussions with interested parties to sell the DB 16.

In April 2014, we completed the sale of our Harbor Island facility near Corpus Christi, Texas for proceeds of approximately $31.7 million and a gain of approximately $25.0 million, which has been recognized in our Americas segment.

In June 2014, as part of our plan to discontinue utilization of Morgan City facility we disposed of several assets, including certain equipment, for aggregate cash proceeds of approximately $13.6 million, resulting in an aggregate gain of approximately $11.4 million, of which approximately $1.3 million was recorded in connection with our Americas restructuring, discussed below. This portion of the gain pertained to impairments previously recorded in the period ended June 30, 2013 in connection with the Americas restructuring.

Also in June 2014, we cancelled a pipelay system originally intended for the Lay Vessel 108 (“LV 108”), which resulted in a $10.7 million improvement to the cancellation cost estimate included in the $37.8 million of vessel impairment charges recognized during the quarter ended December 31, 2013.

Americas and Corporate Restructuring

We commenced a restructuring of our Americas operations during the quarter ended June 30, 2013, which involves our Morgan City, Louisiana, Houston, Texas, New Orleans, Louisiana and Brazil locations. The restructuring involves, among other things, reductions of management, administrative, fabrication and engineering personnel, and discontinued utilization of the Morgan City facility (after the completion of existing backlog projects, which are currently forecasted to be completed in the third quarter of 2014). Future fabrication operations in the Americas segment are expected to be executed using the Altamira, Mexico facility. In addition, we exited our joint venture operation in Brazil. Costs associated with our Americas restructuring activities primarily include severance and other personnel-related costs, costs associated with exiting the joint venture in Brazil, asset impairment and relocation costs, environmental reserves and future unutilized lease costs.

In October 2013, we announced certain executive management changes that became effective during the fourth quarter of 2013. In March 2014, we changed our organizational structure to orient around offshore and subsea business activities through four primary geographic regions. Costs associated with our corporate reorganization activities will primarily include severance, relocation and other personnel-related costs and costs for advisors.

Accrued liabilities associated with restructuring activities were approximately $6.9 million and $8.0 million as of June 30, 2014 and December 31, 2013, respectively.

NOTE 3—LONG-TERM DEBT AND NOTES PAYABLE

During April 2014, we refinanced our existing obligations, and replaced in its entirety, our then existing $950.0 million credit agreement (the “Former Credit Agreement”) with a new credit agreement (the “New Credit Agreement”), which provides for:

• a $400.0 million first-lien, first-out three-year letter of credit facility (the “LC Facility”); and

• a $300.0 million first-lien, second-out five-year term loan (the “Term Loan”).

Additionally, during April 2014, we completed the following new financing transactions:

• the issuance of $500.0 million of second-lien seven-year senior secured notes.

• the issuance of $287.5 million of tangible equity units composed of (1) three-year amortizing, senior unsecured notes, in an aggregate principal amount of $47.5 million, and (2) prepaid common stock purchase contracts.

With the completion of these financing transactions in April 2014, we terminated the bridge loan commitment we had obtained from an affiliate of Goldman, Sachs, & Co. (“Goldman Sachs”). As a result of the termination of the bridge loan commitment, the fee we previously paid to Goldman Sachs to obtain the bridge loan commitment was recognized as interest expense in the quarter ended June 30, 2014. Due to the replacement of the Former Credit Agreement, the unamortized issuance fees related to the Former Credit Agreement were also recognized as interest expense in the quarter ended June 30, 2014. The total additional interest expense related to these items was approximately $28.0 million in the quarter ended June 30, 2014.

The Former Credit Agreement provided for revolving credit borrowings and issuances of letters of credit in an aggregate outstanding amount of up to $950.0 million. Proceeds from borrowings under the Former Credit Agreement were available for working capital needs and other general corporate purposes. At December 31, 2013, there were no borrowings outstanding, and letters of credit issued under the Former Credit Agreement totaled $214.3 million. At December 31, 2013, there was $735.7 million available for borrowings or to meet letter of credit requirements under the Former Credit Agreement. During the year ended December 31, 2013, our outstanding borrowings under the Former Credit Agreement did not exceed $80.0 million, and we had average outstanding borrowings under the Former Credit Agreement of approximately $23.5 million, with an average interest rate of 2.28%. In addition, at December 31, 2013, we had $96.9 million in outstanding unsecured bilateral letters of credit. At March 31, 2014, there was $250.0 million of revolving credit borrowings outstanding under the Former Credit Agreement, all of which were repaid during April 2014.

19

New Credit Facilities

The indebtedness and other obligations under the New Credit Agreement are guaranteed by substantially all of our material, wholly owned subsidiaries, other than our captive insurance subsidiary (collectively, the “Guarantors”). In connection with the New Credit Agreement, we paid certain fees to the lenders thereunder, as well as certain arrangement fees to the arrangers and agents for the New Credit Agreement, which we have capitalized and are amortizing to interest expense over the respective terms of the LC Facility and the Term Loan. We also paid certain fees to the initial purchasers of the senior secured notes and to the underwriter of the tangible equity units referred to below, which we have capitalized and are amortizing to interest expense over the respective terms of the related indebtedness.

LC Facility

The LC Facility provides for an initial letter of credit capacity of $400.0 million and allows for uncommitted increases in capacity of $100.0 million through December 31, 2014 and an additional $100.0 million thereafter, potentially increasing the total capacity to $600.0 million through the term of the LC Facility. Letters of credit issuable under the LC Facility support the obligations of McDermott and its affiliates and joint ventures. The aggregate amount of the LC Facility available for financial letters of credit is capped at 25% of the total LC Facility. As of June 30, 2014, letters of credit issued under the LC Facility totaled $225.3 million, including financial letters of credit of $3.2 million.

The LC Facility is secured on a first-lien, first-out basis (with relative priority over the Term Loan) by pledges of the capital stock of all the Guarantors and mortgages on, or other security interests in, substantially all the tangible and intangible assets of our company and the Guarantors, subject to specific exceptions.

The LC Facility contains various customary affirmative covenants, as well as specific affirmative covenants, including specific reporting requirements and a requirement for ongoing periodic financial reviews by a financial advisor. The LC Facility also requires compliance with various negative covenants, including limitations with respect to the incurrence of other indebtedness and liens, restrictions on acquisitions, capital expenditures and other investments, restrictions on sale/leaseback transactions and restrictions on prepayments of other indebtedness.

The LC Facility requires us to generate consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) of at least certain specified amounts over the term of the facility. The LC Facility also requires us to maintain a ratio of fair market value of vessel collateral to the sum of (1) the outstanding principal amount of the Term Loan, (2) the aggregate amount of undrawn financial letters of credit outstanding under the LC Facility, (3) all drawn but unreimbursed letters of credit under the LC Facility, and (4) mark-to-market foreign exchange exposure that is not cash secured of at least 1.20:1.00. The LC Facility also specifies maximum capital expenditures over the term of the facility and requires us to maintain at least $200.0 million of minimum available cash, at the end of each quarter. We were in compliance with the covenants under the LC Facility as of June 30, 2014.

The LC Facility provides for a commitment fee of 0.50% per year on the unused portion of the LC Facility and letter of credit fees at an annual rate of 2.25% for performance letters of credit and 4.50% for financial letters of credit, as well as customary issuance fees and other fees and expenses.

In addition, the LC Facility permits us to deposit up to $300.0 million with letter of credit issuers to cash collateralize letters of credit. As of June 30, 2014, we had approximately $163.4 million of letters of credit supported by cash collateral that was included in restricted cash and cash equivalents.

Term Loan

The Term Loan is secured on a first-lien, second-out basis (with the LC Facility having relative priority over the Term Loan) by pledges of the capital stock of all the Guarantors and mortgages on, or other security interests in, substantially all tangible and intangible assets of our company and the Guarantors, subject to specific exceptions. As of June 30, 2014, there was $300.0 million in borrowings outstanding under the Term Loan agreement, of which $3.0 million was classified as current notes payable.

The Term Loan requires mandatory prepayments from: (1) the proceeds from the sale of assets, as well as insurance proceeds, in each case subject to certain exceptions, to the extent such proceeds are not reinvested in our business within 365 days of receipt; (2) net cash proceeds from the incurrence of indebtedness not otherwise permitted under the New Credit Agreement; and (3) 50% of amounts deemed to be “excess cash flow,” subject to specified adjustments. The Term Loan also requires quarterly amortization payments equal to $750,000. The Term Loan also provides for a prepayment premium if we prepay or re-price the Term Loan prior to April 16, 2015.

20

The Term Loan requires compliance with various customary affirmative and negative covenants. We must also maintain a ratio of “ownership adjusted fair market value” of marine vessels to the sum of (1) the outstanding principal amount of the Term Loan and (2) the aggregate principal amount of unreimbursed drawings and advances under the LC Facility of at least 1.75:1.00. As of June 30, 2014, we were in compliance with all the covenants under the Term Loan.

The Term Loan was incurred with 25 basis points of original issue discount and bears interest at a floating rate, which can be, at our option, either: (1) a LIBOR rate for a specified interest period (subject to a LIBOR “floor” of 1.00%) plus an applicable margin of 4.25%; or (2) an alternate base rate (subject to a base rate “floor” of 2.00%) plus an applicable margin of 3.25%.

Senior Notes

During April 2014 we issued $500.0 million in aggregate principal amount of 8.000% senior secured notes due 2021 (the “Notes”) in a private placement in accordance with Rule 144A and Regulation S under the Securities Act of 1933, as amended. Interest on the Notes is payable semi-annually in arrears on May 1 and November 1 of each year, beginning on November 1, 2014, at an annual rate of 8%. The Notes are scheduled to mature on May 1, 2021. As of June 30, 2014, there was $500.0 million of Senior Notes outstanding.

The Notes are unconditionally guaranteed on a senior secured basis by the Guarantors, and the Notes are secured on a second—lien basis by pledges of capital stock of certain of our subsidiaries and mortgages and other security interests covering (1) specified marine vessels owned by certain of the Guarantors and (2) substantially all the other tangible and intangible assets of our company and the Guarantors, subject to exceptions for certain assets.

At any time or from time to time on or after May 1, 2017, at our option, we may redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, together with accrued and unpaid interest to the redemption date, if redeemed during the 12-month period beginning May 1 of the years indicated:

Year	Percentage
2017		104	%
2018		102	%
2019 and thereafter		100	%

The Indenture governing the Notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to: (1) incur or guarantee additional indebtedness or issue preferred stock; (2) make investments or certain other restricted payments; (3) pay dividends or distributions on capital stock or purchase or redeem subordinated indebtedness; (4) sell assets; (5) create restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us; (6) create certain liens; (7) sell all or substantially all of our assets or merge or consolidate with or into other companies; (8) enter into transactions with affiliates; and (9) create unrestricted subsidiaries. Many of those covenants would become suspended if the Notes were to attain an investment grade rating from both Moody’s Investors Service, Inc. and Standard and Poor’s Ratings Services and no default has occurred. The covenants mentioned above are subject to a number of important exceptions and limitations.

Tangible Equity Units

During April 2014, we issued 11,500,000 6.25% tangible equity units (“Units”), each with a stated amount of $25.00. Each Unit consists of (1) a prepaid common stock purchase contract and (2) a senior amortizing note due April 1, 2017 (each an “Amortizing Note”) that has an initial principal amount of $4.1266 per Amortizing Note, bears interest at a rate of 7.75% per annum and has a final scheduled installment payment date of April 1, 2017.

The prepaid common stock purchase contracts were accounted for as additional paid-in capital totaling $240.0 million. The Amortizing Notes were recorded as long-term debt totaling $47.5 million, of which $14.5 million was classified as current notes payable.

Each prepaid common stock purchase contract will automatically settle on April 1, 2017, unless settled earlier: (1) at the holder’s option, upon which we will deliver shares of our common stock, based on the applicable settlement rate and applicable market value of our stock as determined under the purchase contract; or (2) at our option, upon which we will deliver shares of our common stock, based upon the stated maximum settlement rate of 3.5562 shares per Unit, subject to adjustment. Potential dilutive common shares for the settlement of the common stock purchase contracts totaled 40.9 million at June 30, 2014, based on that maximum number of shares issuable per Unit. The potential minimum number of shares issuable is 33.4 million, which represents 2.9030 per Unit. The maximum and minimum settlement rates for the Units are subject to adjustment for certain dilutive events.

North Ocean Financing

North Ocean 105

On September 30, 2010, MII, as guarantor, and North Ocean 105 AS, in which we have a 75% ownership interest, as borrower, entered into a financing agreement to finance a portion of the construction costs of the North Ocean 105. The agreement provides for borrowings of up to $69.4 million, bearing interest at 2.76% per year, and requires principal repayment in 17 consecutive semi-annual installments, which commenced on October 1, 2012. Borrowings under the agreement are secured by, among other things, a pledge of all of the equity of North Ocean 105 AS, a mortgage on the North Ocean 105, and a lien on substantially all of the other assets of North Ocean 105 AS. MII unconditionally guaranteed all amounts to be borrowed under the agreement. As of June 30, 2014 and December 31, 2013, there was $53.1 million and $57.2 million, respectively, in borrowings outstanding under this agreement, of which (as of each date) approximately $8.2 million was classified as current notes payable.

North Ocean 102

In December 2009, J. Ray McDermott, S.A. (“JRMSA”), a wholly owned subsidiary of MII, entered into a vessel-owning joint venture transaction with Oceanteam ASA. JRMSA had guaranteed approximately 50% of this debt based on its ownership percentages in the vessel-owning companies. The outstanding debt bore interest at a rate equal to the three-month LIBOR (which was subject to reset every three months) plus a margin of 3.315%. JRMSA paid in full the approximately $31.4 million notes payable balance upon maturity during January 2014. JRMSA expects to exercise its option to purchase Oceanteam ASA’s 50% ownership interest in the vessel-owing companies in December 2014. As of December 31, 2013 we reported a consolidated notes payable of $31.4 million on our consolidated balance sheet, all of which was classified as current notes payable and paid in full in early 2014.

Unsecured Bilateral Letters of Credit and Bank Guarantees

In 2012, McDermott Middle East, Inc, and MII executed a general reimbursement agreement in favor of a bank located in the UAE relating to issuances of bank guarantees in support of contracting activities in the Middle East and India. As of June 30, 2014 and December 31, 2013, bank guarantees issued under these arrangements totaled $50.4 million and $55.8 million, respectively. In 2007 and in 2012, JRMSA and MII executed general unsecured reimbursement agreements in favor of three institutions that were lenders under the Former Credit Agreement relating to issuances of letters of credit in support of contracting activities, primarily in Asia and the Middle East. Letters of credit issued under two of these arrangements have either been replaced by letters of credit under the LC Facility or cash collateralized. The letters of credit issued under these arrangements totaled $12.0 million and $39.8 million as of June 30, 2014 and December 31, 2013, respectively.

On April 20, 2012, McDermott and one of its wholly owned subsidiaries, McDermott Australia Pty. Ltd. (“McDermott Australia”), entered into a secured Letter of Credit Reimbursement Agreement (the “Reimbursement Agreement”) with Australia and New Zealand Banking Group Limited (“ANZ”). In accordance with the terms of the Reimbursement Agreement, ANZ issued letters of credit in the aggregate amount of approximately $109.0 million to support McDermott Australia’s performance obligations under contractual arrangements relating to a field development project. The obligations of McDermott and McDermott Australia under the Reimbursement Agreement are secured by McDermott Australia’s interest in the contractual arrangements and certain related assets. During six months ended June 30, 2014, we replaced these letters of credit with letters of credit under the LC Facility.

Surety Bonds

In 2012 and 2011, MII executed general agreements of indemnity in favor of surety underwriters based in Mexico relating to surety bonds issued in support of contracting activities of J. Ray McDermott de Mèxico, S.A. de C.V. and McDermott, Inc, both subsidiaries of MII. As of June 30, 2014 and December 31, 2013, bonds issued under these arrangements totaled $42.1 million and $43.5 million, respectively. In October 2013, MII executed general agreements of indemnity in favor of surety underwriters relating to surety bonds in support of vessels operating in Brazil. The project requiring these bonds was completed during the quarter allowing us to cancel the outstanding bonds. Accordingly, as of June 30, 2014, there were no bonds issued under these arrangements. As of December 31, 2013, the bonds issued under these arrangements totaled $106.3 million.

NOTE 4—PENSION PLANS

Although we currently provide retirement benefits for most of our U.S. employees through sponsorship of the McDermott Thrift Plan, some of our longer-term U.S. employees and former employees are entitled to retirement benefits under the McDermott (U.S.) Retirement Plan, a non-contributory qualified defined benefit pension plan (the “McDermott Plan”), and several non-qualified supplemental defined benefit pension plans. The McDermott Plan and the non-qualified supplemental defined benefit pension plans are collectively referred to herein as the “Domestic Plans.” The McDermott Plan has been closed to new participants since 2006, and benefit accruals were frozen completely in 2010.

We also sponsor a defined benefit pension plan established under the laws of the Commonwealth of the Bahamas, the J. Ray McDermott, S.A. Third Country National Employees Pension Plan (the “TCN Plan”), which provides retirement benefits for certain of our current and former foreign employees. Effective August 1, 2011, new entry into the TCN Plan was closed, and effective December 31, 2011, benefit accruals under the TCN Plan were frozen. Effective January 1, 2012, we established a new global defined contribution plan to provide retirement benefits to non-U.S. expatriate employees who may have otherwise obtained benefits under the TCN Plan.

Retirement benefits under the McDermott Plan and the TCN Plan are generally based on final average compensation and years of service, subject to the applicable freeze in benefit accruals under the plans. Our funding policy is to fund the plans as recommended by the respective plan actuaries and in accordance with the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or other applicable law. The Pension Protection Act of 2006 (“PPA”) amended ERISA and modified the funding requirements for certain defined benefit pension plans including the McDermott Plan. Funding provisions under the PPA accelerated funding requirements are applicable to the McDermott Plan to ensure full funding of benefits accrued.

NOTE 5—DERIVATIVE FINANCIAL INSTRUMENTS

We enter into derivative financial instruments primarily to hedge certain firm purchase commitments and forecasted transactions denominated in foreign currencies. We record these contracts at fair value on our condensed consolidated balance sheets. Depending on the hedge designation at the inception of the contract, the related gains and losses on these contracts are either: (1) deferred as a component of AOCI until the hedged item is recognized in earnings; (2) offset against the change in fair value of the hedged firm commitment through earnings; or (3) recognized immediately in earnings. At inception and on an ongoing basis, we assess the hedging relationship to determine its effectiveness in offsetting changes in cash flows or fair value attributable to the hedged risk. We exclude from our assessment of effectiveness the portion of the fair value of the forward contracts attributable to the difference between spot exchange rates and forward exchange rates. The ineffective portion of a derivative’s change in fair value and any portion excluded from the assessment of effectiveness are immediately recognized in earnings. Gains and losses on derivative financial instruments that are immediately recognized in earnings are included as a component of gain (loss) on foreign currency-net in our condensed consolidated statements of operations.

As of June 30, 2014, the majority of our foreign currency forward contracts were designated as cash flow hedging instruments. In addition, we deferred approximately $30.1 million of net losses on these derivative financial instruments in AOCI, and we expect to reclassify approximately $30.2 million of deferred losses out of AOCI by October 2017, as hedged items are recognized. The notional value of our outstanding derivative contracts totaled $1.0 billion at June 30, 2014, with maturities extending through 2017. Of this amount, approximately $735.0 million is associated with various foreign currency expenditures we expect to incur on one of our Asia Pacific segment EPCI projects. These instruments consist of contracts to purchase or sell foreign-denominated currencies. As of June 30, 2014, the fair value of these contracts was in a net liability position totaling $2.6 million. The fair value of outstanding derivative instruments is determined using observable financial market inputs, such as quoted market prices, and is classified as Level 2 in nature.

⁽¹⁾  Various U.S. equities and other investments managed under mutual funds

⁽²⁾  Asset-backed and mortgage-backed securities with maturities of up to 26 years

Our Level 2 investments consist primarily of commercial paper, asset-backed commercial paper notes backed by a pool of mortgage-backed securities and mutual funds. The fair value of our Level 2 investments was determined using a market approach which is based on quoted prices and other information for similar or identical instruments.

Our Level 3 investment consists of asset-backed commercial paper notes backed by a pool of mortgage-backed securities. The fair value of this Level 3 investment was based on the calculation of an overall weighted-average valuation, using the prices of the underlying individual securities. Individual securities in the pool were valued based on market observed prices, where available. If market prices were not available, prices of similar securities backed by similar assets were used.

Changes in Level 3 Instrument

The following is a summary of the changes in our Level 3 instrument measured on a recurring basis for the three months and six months ended June 30, 2014 and June 30, 2013:

	Three Months Ended June 30,					Six Months Ended June 30,
	2014		2013			2014			2013
	(In thousands)
Balance at beginning of period	$	—	$	6,157		$	5,557		$	6,343

Balance at end of period	$	—	$	5,902		$	—		$	5,902

Unrealized Gains and Losses on Investments

Our net unrealized gain on investments was $0.2 million as of June 30, 2014. During the year ended December 31, 2013, we recognized other than temporary impairment of $1.6 million on the asset-backed securities and collateralized mortgage obligations. Our net unrealized gain on investments was $0.2 million as of December 31, 2013. The amount of investments in an unrealized loss position for less than twelve months was not significant for either of the periods presented.

Other Financial Instruments

We used the following methods and assumptions in estimating our fair value disclosures for our other financial instruments:

Cash and cash equivalents and restricted cash and cash equivalents. The carrying amounts that we have reported in the accompanying condensed consolidated balance sheets for cash, cash equivalents and restricted cash and cash equivalents approximate their fair values and are classified as Level 1 within the fair value hierarchy.

26

Short-term and long-term debt. The fair value of debt instruments is classified as Level 2 within the fair value hierarchy and is valued using a market approach based on quoted prices for similar instruments traded in active markets. Where quoted prices are not available, the income approach is used to value these instruments based on the present value of future cash flows discounted at estimated borrowing rates for similar debt instruments or on estimated prices based on current yields for debt issues of similar quality and terms.

Forward contracts. The fair value of forward contracts is classified as Level 2 within the fair value hierarchy and is valued using observable market parameters for similar instruments traded in active markets. Where quoted prices are not available, the income approach is used to value forward contracts, which discounts future cash flows based on current market expectations and credit risk.

The estimated fair values of certain of our financial instruments are as follows:

	June 30, 2014						December 31, 2013
	Carrying Amount			Fair Value			Carrying Amount			Fair Value
	(In thousands)
Balance Sheet Instruments
Cash and cash equivalents	$	764,034		$	764,034		$	118,702		$	118,702
Restricted cash and cash equivalents	$	189,871		$	189,871		$	23,652		$	23,652
Investments	$	4,219		$	4,219		$	13,511		$	13,511
Debt	$	(904,375	)	$	(932,590	)	$	(88,562	)	$	(90,005	)
Forward contracts	$	(2,614	)	$	(2,614	)	$	(28,767	)	$	(28,767	)

NOTE 7—STOCK-BASED COMPENSATION

Equity instruments are measured at fair value on the grant date. Stock-based compensation expense is generally recognized on a straight-line basis over the requisite service periods of the awards. Compensation expense is based on awards we expect to ultimately vest. Therefore, we have reduced compensation expense for estimated forfeitures based on our historical forfeiture rates. Our estimate of forfeitures is determined at the grant date and is revised if our actual forfeiture rate is materially different from our estimate.

We use a Black-Scholes model to determine the fair value of certain share-based awards, such as stock options. Additionally, we use a Monte Carlo model to determine the fair value of certain share-based awards that contain market and performance-based conditions. The use of these models requires highly subjective assumptions, such as assumptions about the expected life of the award, vesting probability, expected dividend yield and the volatility of our stock price.

Total stock-based compensation expense, net recognized for the three months ended June 30, 2014 and June 30, 2013 is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2013		2014		2013
	(In thousands)
Stock Options	$	441	$	1,170	$	1,121	$	2,200
Restricted Stock Units		4,586		3,250		7,965		4,987
Performance Shares		217		1,767		545		2,923
Total	$	5,244	$	6,187	$	9,631	$	10,110

Included in stock-based compensation expense, net is a $0.7 million reversal of prior recognized expense resulting from corporate severance arrangements and other personnel-related costs recorded in Restructuring Expenses.

NOTE 8—EARNINGS PER SHARE

The following table sets forth the computation of basic and diluted earnings per common share:

	Three Months Ended June 30,						Six Months Ended June 30,
	2014			2013			2014			2013
	(In thousands, except share and per share amounts)
Net loss attributable to McDermott International, Inc.	$	(10,830	)	$	(149,423	)	$	(60,783	)	$	(128,870	)
Weighted average common shares (basic)		237,395,580			236,199,438			237,178,369			236,070,311
Effect of dilutive securities:
Stock options, restricted stock and restricted stock units		—			—			—			—
Adjusted weighted average common shares and assumed exercises of stock options and vesting of stock awards (diluted)		237,395,580			236,199,438			237,178,369			236,070,311
Basic loss per share
Net loss attributable to McDermott International, Inc.		(0.05	)		(0.63	)		(0.26	)		(0.55	)
Diluted earnings loss per share:
Net loss attributable to McDermott International, Inc.		(0.05	)		(0.63	)		(0.26	)		(0.55	)

Approximately 2.9 million and 3.0 million shares underlying outstanding stock-based awards were excluded from the computation of diluted earnings per share because they were anti-dilutive for the three months and six months ended June 30, 2014, respectively. Approximately 2.9 million shares underlying outstanding stock-based awards were excluded from the computation of diluted earnings per share because they were anti-dilutive for the three months and six months ended June 30, 2013.

Potential dilutive common shares for the settlement of the common stock purchase contracts totaling 40.9 million and 20.4 million shares were considered in the calculation of diluted weighted-average shares for three months and six months ended June 30, 2014, respectively; however, due to our net loss position, they have not been reflected above because they would be anti-dilutive.

NOTE 9—SEGMENT REPORTING

In March 2014, we changed our organizational structure to orient around our offshore and subsea business activities through four primary geographic regions. The four geographic regions, which we consider to be our operating segments, consist of Asia Pacific, Americas, Middle East, and North Sea and Africa. The Caspian is no longer considered an operating segment and will continue to be aggregated in the Middle East reporting segment. The North Sea and Africa operating segment is also aggregated into the Middle East reporting segment due to the proximity of regions and similarities in the nature of services provided, economic characteristics and oversight responsibilities. Accordingly, we continue to report financial results under reporting segments consisting of Asia Pacific, Americas and the Middle East. We also report certain corporate and other non-operating activities under the heading “Corporate and other.” “Corporate and other” primarily reflects corporate personnel and activities, incentive compensation programs and other costs, which are generally fully allocated to our operating segments. The only corporate costs currently not being allocated to our operating segments are the restructuring costs associated with our corporate reorganization.

Reporting segments are measured based on operating income, which is defined as revenues reduced by total costs and expenses and equity in income (loss) of unconsolidated affiliates. Summarized financial information is shown in the following tables:

NOTE 10—COMMITMENTS AND CONTINGENCIES

Investigations and Litigation

On or about August 23, 2004, a declaratory judgment action entitled Certain Underwriters at Lloyd’s London, et al. v. J. Ray McDermott, Inc. et al., was filed by certain underwriters at Lloyd’s, London and Threadneedle Insurance Company Limited (the “London Insurers”), in the 23rd Judicial District Court, Assumption Parish, Louisiana, against MII, J. Ray McDermott, Inc. (“JRMI”) and two insurer defendants, Travelers and INA, seeking a declaration that the London Insurers have no obligation to indemnify MII and JRMI for certain bodily injury claims, including claims for asbestos and welding rod fume personal injury which have been filed by claimants in various state courts. Additionally, Travelers filed a cross-claim requesting a declaration of non-coverage in approximately 20 underlying matters. This proceeding was stayed by the Court on January 3, 2005. We do not believe an adverse judgment or material losses in this matter are probable, and, accordingly, we have not accrued any amounts relating to this contingency. Although there is a possibility of an adverse judgment, the amount or potential range of loss is not estimable at this time. The insurer-plaintiffs in this matter commenced this proceeding in a purported attempt to obtain a determination of insurance coverage obligations for occupational exposure and/or environmental matters for which we have given notice that we could potentially seek coverage. Because estimating losses would require, for every matter, known and unknown, on a case by case basis, anticipating what impact on coverage a judgment would have and a determination of an otherwise expected insured value, damages cannot be reasonably estimated.

On December 16, 2005, a proceeding entitled Antoine, et al. vs. J. Ray McDermott, Inc., et al. (“Antoine Suit”), was filed in the 24th Judicial District Court, Jefferson Parish, Louisiana, by approximately 88 plaintiffs against approximately 215 defendants, including our subsidiaries formerly known as JRMI and Delta Hudson Engineering Corporation (“DHEC”), generally alleging injuries for exposure to asbestos, and unspecified chemicals, metals and noise while the plaintiffs were allegedly employed as Jones Act seamen. This case was dismissed by the Court on January 10, 2007, without prejudice to plaintiffs’ rights to refile their claims. On January 29, 2007, 21 plaintiffs from the dismissed Antoine Suit filed a matter entitled Boudreaux, et al. v. McDermott, Inc., et al. (the “Boudreaux Suit”), in the United States District Court for the Southern District of Texas, against JRMI and our subsidiary formerly known as McDermott Incorporated, and approximately 30 other employer defendants, alleging Jones Act seaman status and generally alleging exposure to welding fumes, solvents, dyes, industrial paints and noise. The Boudreaux Suit was transferred to the United States District Court for the Eastern District of Louisiana on May 2, 2007, which entered an order in September 2007 staying the matter until further order of the Court due to the bankruptcy filing of one of the co-defendants. On June 18, 2014, the Boudreaux Suit was voluntarily dismissed without prejudice. Additionally, on January 29, 2007, another 43 plaintiffs from the dismissed Antoine Suit filed a matter entitled Antoine, et al. v. McDermott, Inc., et al. (the “New Antoine Suit”), in the 164th Judicial District Court for Harris County, Texas, against JRMI, our subsidiary formerly known as McDermott Incorporated and approximately 65 other employer defendants and 42 maritime products defendants, alleging Jones Act seaman status and generally alleging personal injuries for exposure to asbestos and noise. On April 27, 2007, the District Court entered an order staying all activity and deadlines in the New Antoine Suit, other than service of process and answer/appearance dates, until further order of the Court. The New Antoine Suit plaintiffs filed a motion to lift the stay on February 20, 2009, which is pending before the Texas District Court. On April 4, 2014, 20 of the plaintiffs in the New Antoine Suit voluntarily dismissed their claims against McDermott without prejudice to re-filing. The remaining plaintiffs seek monetary damages in an unspecified amount and attorneys’ fees. We cannot reasonably estimate the extent of a potential judgment against us, if any, and we intend to vigorously defend this suit.

On August 15, 2013 and August 20, 2013, two separate alleged purchasers of our common stock filed purported class action complaints against us, Stephen M. Johnson and Perry L. Elders in the United States District Court for the Southern District of Texas. Both of the complaints sought to represent a class of purchasers of our stock between November 6, 2012 and August 5, 2013, and alleged, among other things, that the defendants violated federal securities laws by disseminating materially false and misleading information and failing to disclose material information relating to weaknesses in project bidding and execution, poor risk evaluation,

30

poor project management and losses in each of our reporting segments. Each complaint sought relief, including unspecified compensatory damages and an award for attorneys’ fees and other costs. By order dated December 5, 2013, the District Court consolidated the two cases and appointed a lead plaintiff and lead plaintiff’s counsel. The lead plaintiff filed a consolidated amended complaint on February 6, 2014. The consolidated amended complaint asserts substantially the same claims as were made in the two original complaints, with some additional factual allegations, and purports to extend the class period to August 6, 2013. It also seeks relief, including unspecified compensatory damages and an award for attorneys’ fees and other costs. On April 7, 2014, MII and the other defendants filed a motion to dismiss the case. On May 22, 2014, the lead plaintiff filed an opposition to the motion to dismiss, and MII and the other defendants filed a reply in support of the defendants’ motion to dismiss on June 23, 2014. The motion to dismiss is still pending before the District Court. We believe the substantive allegations contained in the consolidated amended complaint are without merit, and we intend to defend against these claims vigorously.

Additionally, due to the nature of our business, we and our affiliates are, from time to time, involved in litigation or subject to disputes or claims related to our business activities, including, among other things:

• performance—or warranty-related matters under our customer and supplier contracts and other business arrangements; and

• workers’ compensation claims, Jones Act claims, occupational hazard claims, including asbestos-exposure claims, premises liability claims and other claims.

Based upon our prior experience, we do not expect that any of these other litigation proceedings, disputes and claims will have a material adverse effect on our consolidated financial condition, results of operations or cash flows; however, because of the inherent uncertainty of litigation and, in some cases, the availability and amount of potentially applicable insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs.

Environmental Matters

We have been identified as a potentially responsible party at various cleanup sites under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”). CERCLA and other environmental laws can impose liability for the entire cost of cleanup on any of the potentially responsible parties, regardless of fault or the lawfulness of the original conduct. Generally, however, where there are multiple responsible parties, a final allocation of costs is made based on the amount and type of wastes disposed of by each party and the number of financially viable parties, although this may not be the case with respect to any particular site. We have not been determined to be a major contributor of wastes to any of these sites. On the basis of our relative contribution of waste to each site, we expect our share of the ultimate liability for the various sites will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows in any given year.

At June 30, 2014, we had total environmental reserves of $6.0 million, all of which was included in noncurrent liabilities. We established an environmental reserve of $5.6 million in connection with our plan to discontinue the utilization of our Morgan City fabrication facility. Inherent in the estimates of those reserves and recoveries are our expectations regarding the levels of contamination, remediation costs and recoverability from other parties, which may vary significantly as remediation activities progress. Accordingly, changes in estimates could result in material adjustments to our operating results, and the ultimate loss may differ materially from the amounts we have provided for in our consolidated financial statements.

Contracts Containing Liquidated Damages Provisions

Some of our contracts contain provisions that require us to pay liquidated damages if we are responsible for the failure to meet specified contractual milestone dates and the applicable customer asserts a claim under these provisions. These contracts define the conditions under which our customers may make claims against us for liquidated damages. In many cases in which we have historically had potential exposure for liquidated damages, such damages ultimately were not asserted by our customers. As of June 30, 2014, it is possible that we may incur liabilities for liquidated damages aggregating approximately $133.8 million, of which approximately $37.5 million has been recorded in our financial statements, based on our actual or projected failure to meet certain specified contractual milestone dates. The dates for which these potential liquidated damages could arise extend to June 2015. We believe we will be successful in obtaining schedule extensions or other customer-agreed changes that should resolve the potential for unaccrued liquidated damages. Accordingly, we believe that no amounts for these unaccrued liquidated damages in excess of the amounts currently reflected in our financial statements are probable of being paid by us. However, we may not achieve relief on some or all of the issues involved and, as a result, could be subject to higher damage amounts.

31

Contractual Obligations

As of June 30, 2014, we had outstanding obligations related to our new vessel construction contracts on the LV 108 and DLV 2000 of $482.2 million in the aggregate, with $237.2 million and $245.0 million due in the years ending December 31, 2014 and 2015, respectively.

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

In this quarterly report on Form 10-Q, unless the context otherwise indicates, “we,” “us” and “our” mean McDermott International, Inc. and its consolidated subsidiaries.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

We are including the following discussion to inform our existing and potential security holders generally of some of the risks and uncertainties that can affect our company and to take advantage of the “safe harbor” protection for forward-looking statements that applicable federal securities law affords. This information should be read in conjunction with the unaudited condensed consolidated financial statements and the notes thereto included under Item 1 and the audited consolidated financial statements and the related notes and Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our annual report on Form 10-K for the year ended December 31, 2013.

From time to time, our management or persons acting on our behalf make forward-looking statements to inform existing and potential security holders about our company. These statements may include projections and estimates concerning the scope, execution, timing and success of specific projects and our future backlog, revenues, income and capital spending. Forward-looking statements are generally accompanied by words such as “estimate,” “project,” “predict,” “forecast,” “believe,” “expect,” “anticipate,” “plan,” “seek,” “goal,” “could,” “may,” or “should” or other words that convey the uncertainty of future events or outcomes. Sometimes we will specifically describe a statement as being a forward-looking statement and refer to this cautionary statement.

These forward-looking statements include, but are not limited to, statements that relate to, or statements that are subject to risks, contingencies or uncertainties that relate to:

• future levels of revenues, operating margins, income from operations, net income or earnings per share;

• outcome of project awards and scope, execution and timing of specific projects, including timing to complete and cost to complete these projects;

• future project activities, including the commencement and subsequent timing of marine or installation campaigns on specific projects;

• estimates of percentage of completion and contract profits or losses;

• anticipated levels of demand for our products and services;

• global demand for oil and gas and fundamentals of the oil and gas industry;

• expectations regarding the trend towards offshore development of oil and gas;

• market outlook for the EPCI market, including subsea;

• expectations regarding backlog;

• future levels of capital, environmental or maintenance expenditures;

• the success or timing of completion of ongoing or anticipated capital or maintenance projects;

• the adequacy of our sources of liquidity and capital resources;

• interest expense;

• the effectiveness of our derivative contracts in mitigating foreign currency risk;

• results of our capital investment program;

• expectations regarding the acquisition or divestiture of assets;

• the ability to dispose of assets held for sale in a timely manner or for a price at or above net realizable value;

• the restructuring of our Americas operations, including the expected costs and timing of cost recognition;

• the potential effects of judicial or other proceedings on our business, financial condition, results of operations and cash flows; and

• the anticipated effects of actions of third parties such as competitors, or federal, foreign, state or local regulatory authorities, or plaintiffs in litigation.

33

These forward-looking statements speak only as of the date of this report; we disclaim any obligation to update these statements unless required by securities law, and we caution you not to rely on them unduly. We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks, contingencies and uncertainties relate to, among other matters, the following:

• general economic and business conditions and industry trends;

• general developments in the industries in which we are involved;

• decisions about offshore developments to be made by oil and gas companies;

• the highly competitive nature of our industry;

• our ability to appropriately bid, estimate and effectively perform projects on time, in accordance with the schedules established by the applicable contracts with customers;

• changes in project design or schedule;

• changes in scope or timing of work to be completed under contracts;

• cancellations of contracts, change orders and other modifications and related adjustments to backlog and the resulting impact from using backlog as an indicator of future revenues or earnings;

• the collectability of amounts reflected in change orders and claims relating to work previously performed on contracts;

• the capital investment required to maintain and/or upgrade our fleet of vessels;

• the ability of our suppliers and subcontractors to deliver raw materials in sufficient quantities and/or perform in a timely manner;

• volatility and uncertainty of the credit markets;

• our ability to comply with covenants in our credit agreements and other debt instruments and availability, terms and deployment of capital;

• the unfunded liabilities of our pension plans may negatively impact our liquidity and, depending upon future operations, may impact our ability to fund our pension obligations;

• the continued availability of qualified personnel;

• the operating risks normally incident to our lines of business, including the potential impact of liquidated damages;

• natural or man-caused disruptive events that could damage our facilities, equipment or our work-in-progress and cause us to incur losses and/or liabilities;

• equipment failure;

• changes in, or our failure or inability to comply with, government regulations;

• adverse outcomes from legal and regulatory proceedings;

• impact of potential regional, national and/or global requirements to significantly limit or reduce greenhouse gas and other emissions in the future;

• changes in, and liabilities relating to, existing or future environmental regulatory matters;

• changes in tax laws;

• rapid technological changes;

• the consequences of significant changes in interest rates and currency exchange rates;

• difficulties we may encounter in obtaining regulatory or other necessary approvals of any strategic transactions;

• the risks associated with integrating acquired businesses;

• the risk we may not be successful in updating and replacing current information technology;

• social, political and economic situations in countries where we do business;

• the risks associated with our international operations, including local content requirements;

34

• interference from adverse weather or sea conditions;

• the possibilities of war, other armed conflicts or terrorist attacks;

• the effects of asserted and unasserted claims and the extent of available insurance coverages;

• our ability to obtain surety bonds, letters of credit and financing;

• our ability to maintain builder’s risk, liability, property and other insurance in amounts and on terms we consider adequate and at rates that we consider economical;

• the aggregated risks retained in our captive insurance subsidiary; and

• the impact of the loss of insurance rights as part of the Chapter 11 Bankruptcy settlement concluded in 2006 involving several of our former subsidiaries.

We believe the items we have outlined above are important factors that could cause estimates in our financial statements to differ materially from actual results and those expressed in a forward-looking statement made in this quarterly report or elsewhere by us or on our behalf. We have discussed many of these factors in more detail elsewhere in this report and in our annual report on Form 10-K for the year ended December 31, 2013. These factors are not necessarily all the factors that could affect us. Unpredictable or unanticipated factors we have not discussed in this report could also have material adverse effects on actual results of matters that are the subject of our forward-looking statements. We do not intend to update our description of important factors each time a potential important factor arises, except as required by applicable securities laws and regulations. We advise our security holders that they should (1) be aware that factors not referred to above could affect the accuracy of our forward-looking statements and (2) use caution and common sense when considering our forward-looking statements.

Recent Developments

Refinancing Transactions

During April 2014, we refinanced our existing obligations, and replaced in its entirety, our then existing $950.0 million credit agreement (the “Former Credit Agreement”) with a new credit agreement (the “New Credit Agreement”), which provides for:

• a $400.0 million first-lien, first-out three-year letter of credit facility (the “LC Facility”); and

• a $300.0 million first-lien, second-out five-year term loan (the “Term Loan”).

Additionally, during April 2014, we completed the following new financing transactions:

• the issuance of $500.0 million of second-lien seven-year senior secured notes.

• the issuance of $287.5 million of tangible equity units composed of (1) three-year amortizing, senior unsecured notes, in an aggregate principal amount of $47.5 million, and (2) prepaid common stock purchase contracts.

With the completion of these financing transactions in April 2014, we terminated the bridge loan commitment we had obtained from an affiliate of Goldman, Sachs, & Co. (“Goldman Sachs”). As a result of the termination of the bridge loan commitment, the fee we previously paid to Goldman Sachs to obtain the bridge loan commitment was recognized as interest expense in the quarter ended June 30, 2014. Due to the replacement of the Former Credit Agreement, the unamortized issuance fees related to the Former Credit Agreement were also recognized as interest expense in the quarter ended June 30, 2014. The total additional interest expense related to these items was approximately $28.0 million in the quarter ended June 30, 2014.

Non-Core Asset Sales

We previously committed to a plan to sell four of our multi-function marine vessels, specifically the Bold Endurance, DB 16, DB 26 and the DLB KP1. Assets classified as held for sale are no longer depreciated. During the six months ended June 30, 2014, we completed the sale of the DLB KP1 for aggregate cash proceeds of approximately $8.4 million, resulting in a gain of approximately $6.4 million recognized in our Middle East segment. During the six months ended June 30, 2013 we completed the sale of the Bold Endurance and the DB 26 for aggregate cash proceeds of approximately $32.0 million, resulting in an aggregate gain of approximately $12.5 million. We remain in discussions with interested parties to sell the DB16.

In April 2014, we completed the sale of our Harbor Island facility near Corpus Christi, Texas for proceeds of approximately $31.7 million and a gain of approximately $25.0 million, which has been recognized in our Americas segment.

In June 2014, as part of our plan to discontinue utilization of Morgan City facility we disposed of several assets for aggregate cash proceeds of approximately $13.6 million, resulting in an aggregate gain of approximately $11.4 million, of which approximately $1.3 million was recorded in connection with our Americas restructuring, discussed below. This portion of the gain pertains to impairments previously recorded in the period ended June 30, 2013 in connection with the Americas restructuring.

35

Also in June 2014, we cancelled a pipelay system originally intended for the Lay Vessel 108 (“LV 108”), which resulted in a $10.7 million improvement to the cancellation cost estimate included in the $37.8 million of vessel impairment charges recognized during the quarter ended December 31, 2013.

Americas and Corporate Restructuring

We commenced a restructuring of our Americas operations during the quarter ended June 30, 2013, which involves our Morgan City, Louisiana, Houston, Texas, New Orleans, Louisiana and Brazil locations. The restructuring involves, among other things, reductions of management, administrative, fabrication and engineering personnel, and discontinued utilization of the Morgan City facility (after the completion of existing backlog projects, which are currently forecasted to be completed in the third quarter of 2014). Future fabrication operations in the Americas segment are expected to be executed using the Altamira, Mexico facility. In addition, we exited our joint venture operation in Brazil. Costs associated with our Americas restructuring activities primarily include severance and other personnel-related costs, costs associated with exiting the joint venture in Brazil, asset impairment and relocation costs, environmental reserves and future unutilized lease costs.

In October 2013, we announced certain executive management changes that became effective during the fourth quarter of 2013. In March 2014, we changed our organizational structure to orient around offshore and subsea business activities through four primary geographic regions. Costs associated with our corporate reorganization activities will primarily include severance, relocation and other personnel-related costs and costs for advisors.

Accounting for Contracts

We execute our contracts through a variety of methods, including fixed-price, cost reimbursable, cost-plus, day-rate and unit-rate basis or some combination of those methods, with fixed-price being the most prevalent. Contracts are usually awarded through a competitive bid process. Factors that customers may consider include price, facility or equipment availability, technical capabilities of equipment and personnel, efficiency, safety record and reputation.

Fixed-price contracts are for a fixed amount to cover costs and any profit element for a defined scope of work. Fixed-price contracts entail more risk to us because they require us to predetermine both the quantities of work to be performed and the costs associated with executing the work.

We have contracts that extend beyond one year. Most of our long-term contracts have provisions for progress payments. We attempt to cover anticipated increases in labor, material and service costs of our long-term contracts either through an estimate of such charges, which is reflected in the original price, or through risk-sharing mechanisms, such as escalation or price adjustments for items such as labor and commodity prices.

We generally recognize our contract revenues and related costs on a percentage-of-completion basis. Accordingly, for each contract, we regularly review contract price and cost estimates as the work progresses and reflect adjustments in profit proportionate to the percentage of completion of the related project in the period when we revise those estimates. To the extent that these adjustments result in a reduction or elimination of previously reported profits with respect to a project, we would recognize a charge against current earnings, which could be material.

Our arrangements with customers frequently require us to provide letters of credit, bid and performance bonds or guarantees to secure bids or performance under contracts. While these letters of credit, bonds and guarantees may involve significant dollar amounts, historically, there have been no material payments to our customers under these arrangements.

Some of our contracts contain provisions that require us to pay liquidated damages if we are responsible for the failure to meet specified contractual milestone dates and the applicable customer asserts a claim under those provisions. Those contracts define the conditions under which our customers may make claims against us for liquidated damages. In many cases in which we have historically had potential exposure for liquidated damages, such damages ultimately were not asserted by our customers. As of June 30, 2014, it is possible that we may incur liabilities for liquidated damages aggregating to approximately $133.8 million, of which approximately $37.5 million has been recorded in our financial statements, based on our actual or projected failure to meet certain specified contractual milestone dates. The dates for which these potential liquidated damages could arise extend to June 2015. We believe we will be successful in obtaining schedule extensions or other customer-agreed changes that should resolve the potential for unaccrued liquidated damages. Accordingly, we believe that no amounts for these unaccrued liquidated damages in excess of the amounts currently reflected in our financial statements are probable of being paid by us. However, we may not achieve relief on some or all of the issues involved and, as a result, could be subject to higher damage amounts.

36

Change orders, which are a normal and recurring part of our business, can increase (sometimes substantially) the future scope and cost of a job. Therefore, change order awards (although frequently beneficial in the long term) can have the short-term effect of reducing the job percentage of completion and thus the revenues and profits recognized to date. We regularly review contract price and cost estimates as the work progresses and reflect adjustments in profit, proportionate to the job percentage of completion in the period when those estimates are revised. Revenue from unapproved change orders is recognized to the extent of amounts management expects to recover or costs incurred. Unapproved change orders that are disputed by the customer are treated as claims.

In the event of a contract deferral or cancellation, we generally would be entitled to recover costs incurred, settlement expenses and profit on work completed prior to deferral or termination. Significant or numerous cancellations could adversely affect our business, financial condition, results of operations and cash flows.

Critical Accounting Policies and Estimates

For a discussion of critical accounting policies and estimates we use in the preparation of our consolidated financial statements, refer to Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our annual report on Form 10-K for the year ended December 31, 2013. See Note 1 to our unaudited condensed consolidated financial statements included in this report for information on recently adopted accounting standards.

Business Segments and Results of Operations

Business Segments

In March 2014, we changed our organizational structure to orient around our offshore and subsea business activities through four primary geographic regions. The four geographic regions, which we consider to be our operating segments, consist of Asia Pacific, Americas, Middle East, and North Sea and Africa. The Caspian is no longer considered an operating segment and will continue aggregated in the Middle East reporting segment. The North Sea and Africa operating segment is also aggregated into the Middle East reporting segment due to the proximity of regions and similarities in the nature of services provided, economic characteristics and oversight responsibilities. Accordingly, we continue to report financial results under reporting segments consisting of Asia Pacific, Americas and the Middle East. We also report certain corporate and other non-operating activities under the heading “Corporate and other.” “Corporate and other” primarily reflects corporate personnel and activities, incentive compensation programs and other costs, which are generally fully allocated to our operating segments. The only Corporate costs currently not be allocated to our operating segments are the restructuring costs associated with our corporate reorganization. See Note 9 for summarized financial information on our segments.

Asia Pacific Segment

Through our Asia Pacific segment, we serve the needs of customers primarily in Australia, Indonesia, Vietnam, Malaysia and Thailand. Project focus in this segment includes the fabrication and installation of fixed and floating structures and the installation of pipelines and subsea systems. The majority of our projects in this segment are performed on an engineering, procurement, construction and installation (“EPCI”) basis. Engineering and procurement services are provided by our Singapore office and are supported by additional resources located in Chennai, India. The primary fabrication facility for this segment is located on Batam Island, Indonesia. Additionally, through our equity ownership interest in two separate joint ventures, we have access to fabrication capacity in China and Malaysia.

Middle East Segment

Through our Middle East segment, which includes the Caspian region, the North Sea and Africa, we serve the needs of customers in Saudi Arabia, Qatar, the United Arab Emirates (U.A.E.), Kuwait, India, Azerbaijan, Russia, the North Sea, West Africa, and East Africa. Project focus in this segment relates primarily to the fabrication and offshore installation of fixed and floating structures and the installation of pipelines and subsea systems. The majority of our projects in this segment are performed on an EPCI basis. Engineering and procurement services are provided by our Dubai, U.A.E., Chennai, India, Al Khobar, Saudi Arabia and United Kingdom offices and are supported by additional resources from our Houston office. The primary fabrication facility for this segment is located in Dubai, U.A.E.

37

Americas Segment

Through our Americas segment, we serve the needs of customers primarily in the United States, Brazil, Mexico and Trinidad. Project focus in this segment includes the fabrication and installation of fixed and floating structures and the installation of pipelines and subsea systems. Engineering and procurement services are supported by engineering resources in Chennai, India, Dubai, U.A.E. and Houston. The primary fabrication facility for this segment is located in Altamira, Mexico. We are in the process of preparing for the discontinued utilization of the Morgan City fabrication facility, as further discussed above under the caption “—Recent Developments—Americas and Corporate Restructuring”

The above-mentioned fabrication facilities in each segment are equipped with a wide variety of heavy-duty construction and fabrication equipment, including cranes, welding equipment, machine tools and robotic and other automated equipment. Project installation is performed by major construction vessels, which we own or lease and are stationed throughout the various regions and provide structural lifting/lowering and pipelay services. These major construction vessels are supported by our multi-function vessels and chartered vessels from third parties to perform a wide array of installation activities that include anchor handling, pipelay, cable/umbilical lay, dive support and hookup/commissioning.

Three months ended June 30, 2014 vs. three months ended June 30, 2013

Revenues

Revenues declined approximately 26%, or $171.2 million, to $476.1 million in the three months ended June 30, 2014 compared to $647.3 million for the corresponding prior-year period, primarily attributable to decreases in our Asia Pacific and Americas segments.

Revenues in our Asia Pacific segment declined approximately 50%, or $116.0 million, largely due to the completion of two of our EPCI projects in Australia and a marine installation project in Malaysia that had significant marine activity during the three months ended June 30, 2013 and were completed during the year ended December 31, 2013. These decreases were partially offset by revenues associated with marine activity on a newly awarded project in Brunei and fabrication activity on an EPCI project in Australia during the three months ended June 30, 2014.

Revenues in our Americas segment decreased approximately 33%, or $60.8 million. The decrease was primarily due to reduced fabrication activity in the region as a result of the reduced utilization of our Morgan City fabrication facility in 2014 and the substantial completion of a project in the Altamira facility prior to the quarter ended June 30, 2014, and, to a lesser extent, reduced offshore marine activity due to the completion of multiple projects during the year ended December 31, 2013. The decrease was partially offset by revenues associated with commencement of marine activity on a subsea project in U.S. Gulf of Mexico during the three months ended June 30, 2014.

Revenues relating to projects in a loss position were approximately $77.1 million during the three months ended June 30, 2014 as compared to $58.8 million during the three months ended June 30, 2013.

Cost of Operations

Cost of operations decreased approximately 40%, or $291.0 million, in the three months ended June 30, 2014 as compared to the corresponding prior-year period, primarily due to reduced activity in all our segments.

Cost of operations in our Asia Pacific segment decreased by $151.2 million, primarily led by the completion of marine activity on a subsea project in Malaysia during the period ended June 30, 2014. This project, which was in a loss position, incurred significant increases in cost estimates of approximately $62.0 million related to the availability of marine vessels during the three months ended June 30, 2013, as disclosed in Note 1—Use of Estimates. During the three months ended June 30, 2014, this project also experienced positive changes in cost estimates of approximately $10.2 million, mainly due to project close-out savings on marine spread and procurement costs. The decrease in cost of operations was also driven by the prior completion of marine activity on an EPCI project in Australia and a marine installation project in Malaysia that had significant activity during the three months ended June 30, 2013. These decreases were partially offset by costs associated with marine activity on a newly awarded project in Brunei and fabrication activity on an EPCI project in Australia during the three months ended June 30, 2014.

Cost of operations in our Middle East segment decreased by $77.8 million, primarily due to attributable to the substantial completion of activities on multiple EPCI projects in Saudi Arabia, India and a pipelay project in the Caspian. These projects had significant marine activity during the three months ended June 30, 2013 and were substantially completed prior to the quarter ended June 30, 2014. In addition, one of these EPCI projects in Saudi Arabia incurred significant increases in cost estimates of approximately $38.0 million during the three months ended June 30, 2013, due to an extended offshore hookup campaign. While the project recognized losses in the six months ended June 30, 2013, it remains in a profitable position. These decreases were partially offset by costs associated with increased activity on an EPCI project in Saudi Arabia.

Cost of operations in our Americas segment decreased by $53.8 million. The decrease was primarily due to reduced fabrication activity in the region due to the reduced utilization of our Morgan City fabrication facility and the substantial completion of a project in the Altamira facility prior to the quarter ended June 30, 2014, and, to a lesser extent, reduced offshore marine activity due to the completion of multiple projects during the year ended December 31, 2013. The decrease was partially offset by increased marine activity associated with the commencement of marine activity on a subsea project in the U.S. Gulf of Mexico during the three months ended June 30, 2014.

Operating Income (Loss)

Operating results improved approximately $177.6 million in the three months ended June 30, 2014 compared to the corresponding prior-year period, attributable to improvements in all segments.

40

Operating income in our Asia Pacific segment improved by $36.8 million in the three months ended June 30, 2014 compared to the corresponding prior-year period. The improvement was primarily due to the completion of marine activity on a project in Malaysia during 2014. This project, which was in a loss position, incurred significant increases in cost estimates of approximately $62.0 million related to the availability of marine vessels during the three months ended June 30, 2013, as disclosed in Note 1—Use of Estimates. During the three months ended June 30, 2014, this project also experienced positive changes in cost estimates of approximately $10.2 million, mainly due to project close out savings on marine spread and procurement costs, adding to the improvement in operating income during the quarter. Marine activity on a vessel charter project also added to the improvement during the three months ended June 30, 2014. These improvements were partially offset by reductions in operating income of approximately $30.5 million from an EPCI project in Australia and a marine installation project in Malaysia that had significant marine activity during the three months ended June 30, 2013 and were completed by December 31, 2013.

Operating results in our Middle East segment improved by approximately $81.4 million in the three months ended June 30, 2014 compared to the corresponding prior-year period. One of our EPCI projects in Saudi Arabia we have an improvement of $33.6 million during the three months ended June 30, 2014. The improvement was primarily due to the significant cost estimate increases of approximately $38.0 million during the three months ended June 30, 2013 associated with an extended offshore hookup campaign. On a pipelay project in the Caspian, operating income improved by approximately $26.4 million due to increased revenue and revised cost estimates of approximately $29.2 million, primarily due to increased cost recovery estimates based on positive developments during the three months ended June 30, 2014 from the ongoing project close-out process with the customer . Increased marine activity on another project in Saudi Arabia during the three months ended June 30, 2014 also contributed to the improvement.

The Americas segment recognized operating income of $11.1 million in the three months ended June 30, 2014 compared to an operating loss of $48.7 million in the three months ended June 30, 2013. This change was primarily due to favorable changes in estimates on three projects, gains on sales of assets and reduced restructuring charges as compared to the corresponding prior-year period.

On an EPCI project in Altamira, we increased our estimated costs to complete by approximately $20.0 million, primarily due to project fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be complete in the fourth quarter of 2015. On a subsea project in U.S. Gulf of Mexico, we recorded a net increase in costs of approximately $13.7 million primarily due to increased estimated costs to complete of approximately $23.3 million due to mechanical downtime on the North Ocean 102 (the “NO 102”), partially offset by profit from approved change orders. These deteriorations were partly offset by changes in cost estimates of approximately $30.0 million as a result of close-out improvements on an EPCI project in Brazil from marine cost reductions upon completion of activities and increased recoveries due to successful developments from the ongoing approval process for additional weather related compensation.

Gain on asset sales included approximately $25.0 million from the sale of our Harbor Island facility near Corpus Christi, Texas and approximately $10.1 million (net of the $1.3 million recorded in connection with the Americas restructuring, as discussed under “—Recent Developments—Non Core Asset Sales,” above) from assets disposed from our Morgan City fabrication facility as a result of our discontinued utilization of that facility.

Restructuring costs in the Americas segment decreased by $14.5 million during the three months ended June 30, 2014 as compared to the three months ended June 30, 2013.

Operating Margins

Operating income is frequently influenced by the resolution of change orders, project close-outs and settlements, which generally can cause operating margins to improve during the period in which these items are approved or finalized as these items generally contribute higher operating margins. While we expect change orders, close-outs and settlements to continue as part of our normal business activities, the period in which they are recognized is largely driven by the finalization of agreements with customers and suppliers and, as a result, is difficult to predict. Additionally, the future margin increases or decreases associated with these items are difficult to predict, due to, among other items, the difficulty of predicting the timing of recognition of change orders, close-outs and settlements and the timing of new project awards.

Other Items in Operating Income

Selling, general and administrative expenses increased $4.3 million in the three months ended June 30, 2014 as compared to the three months ended June 30, 2013, primarily as a result of increased amortization of deferred non-cash benefit plan losses.

41

Gain on sale of assets for three months ended June 30, 2014 included the effect of cancellation of a pipelay system originally intended for the LV 108, which resulted in a $10.7 million improvement to the cancellation cost estimate included in the $37.8 million of vessel impairment charges recognized during the quarter ended December 31, 2013.

Operating income was also impacted by reduction in restructuring expense of approximately $14.2 million in the three months ended June 30, 2014 as discussed above under “—Recent Developments—Americas and Corporate Restructuring.”

Equity in loss of unconsolidated affiliates decreased by $2.1 million in the three months ended June 30, 2014, primarily due to impairment of two investments in unconsolidated affiliates during 2013, which had generated losses during the three months ended June 30, 2013, and improved results generated by our FloaTEC joint venture.

Other Items

Results for the quarter ended June 30, 2014 were significantly impacted by interest expense from new financing arrangements as discussed in Note 3. The quarter ended June 30, 2013 was not significantly impacted by interest expense.

Gain on foreign currency—net decreased by $2.3 million to a gain of $6.6 million in the three months ended June 30, 2014 from a gain of $8.9 million in the three months ended June 30, 2013. The decrease reflects foreign currency gains of $1.5 million and gains related to derivative instruments and hedging activities of $5.1 million, mainly from the foreign currency contracts entered for one of Asia Pacific segment EPCI projects, through 2017, recognized during the three months ended June 30, 2014, as compared to foreign currency gains of $1.6 million and gains related to derivative instruments and hedging activities of $7.3 million recognized during the three months ended June 30, 2013.

At June 30, 2014, our derivative financial instruments consisted primarily of foreign currency forward contracts. The notional value of our outstanding derivative contracts totaled approximately $1.0 billion at June 30, 2014, with maturities extending through 2017. Of this amount, approximately $735.0 million is associated with various foreign currency expenditures we expect to incur in connection with an EPCI project in the Asia Pacific segment.

Provision for Income Taxes

For the three months ended June 30, 2014, we recognized a loss before provision for income taxes of $4.3 million, compared to loss of $140.2 million in the three months ended June 30, 2013. In the aggregate, the provision for income taxes was $4.8 million and $5.9 million for the three months ended June 30, 2014 and 2013, respectively.

We were able to utilize past losses in certain jurisdictions which were previously un-benefited to offset our improving income (primarily U.S., Saudi Arabia, Malaysia and Singapore). Therefore, the change in our provision for income tax was minimal.

Noncontrolling Interests

Net income attributable to noncontrolling interests decreased by $1.6 million to $1.7 million in the three months ended June 30, 2014 compared to $3.3 million for the three months ended June 30, 2013, primarily due to losses in our Malaysian subsidiary, Berlian McDermott Sdn. Bhd.

42

Six Months ended June 30, 2014 Compared to Six Months ended June 30, 2013

Revenues

Revenues decreased approximately 26%, or $374.8 million, to approximately $1.1 billion in the six months ended June 30, 2014 compared to $1.5 billion for the corresponding prior-year period, primarily due to decreases in our Asia Pacific segment.

Revenues in our Asia Pacific segment decreased approximately 50%, or $280.0 million, largely due to the completion of two of our EPCI projects in Australia and a marine installation project in Malaysia that had significant marine activity during the six months ended June 30, 2013 and were completed during the year ended December 31, 2013. Also contributing to revenue decrease was approximately $50 million of successful project close-out negotiations and resolution of pending change orders with our customer on one of the EPCI projects in Australia which occurred in the corresponding prior-year period. These decreases were partially offset by revenues associated with increased marine activity on a recently completed project in Malaysia, a newly awarded project in Brunei and fabrication activity on an ongoing EPCI project in Australia during the six months ended June 30, 2014.

Revenues in our Middle East segment decreased approximately 12%, or $67.5 million, primarily due to the substantial completion of a pipelay project in the Caspian, an EPCI project in India and marine activity on an EPCI project in Saudi Arabia, each of which had higher activity during the six months ended June 30, 2013 as compared to the six months ended June 30, 2014. These declines were partly offset by increased activity on an EPCI project in Saudi Arabia.

Revenues in our Americas segment decreased approximately 8%, or $27.3 million. The decrease was primarily due to lower fabrication activity in the region as a result of the reduced utilization of our Morgan City fabrication facility in 2014 and the substantial completion of a project in the Altamira facility prior to the quarter ended June 30, 2014, and, to a lesser extent, reduced offshore marine activity due to the completion of multiple projects during the year ended December 31, 2013. The decrease was partially offset by revenues associated with marine activity in Brazil and the commencement of marine activity on a subsea project in the U.S. Gulf of Mexico during the six months ended June 30, 2014.

Revenues relating to projects in a loss position were approximately $184.1 million during the six months ended June 30, 2014 as compared to approximately $193.0 million during the six months ended June 30, 2013.

Cost of Operations

Cost of operations decreased approximately 29%, or $412.3 million, to $1.0 billion in the six months ended June 30, 2014 compared to the six months ended June 30, 2013, primarily attributable to decreases in activity in our Asia Pacific and Middle East segments.

Costs of operations in our Asia Pacific segment decreased by $241.0 million, primarily due to the prior completion of two EPCI projects in Australia and a marine installation project in Malaysia that had significant activity during the six months ended June 30, 2013 and were completed during the year ended December 31, 2013. The decrease was also due to the completion of marine activity on a subsea project in Malaysia during the three months ended June 30, 2014. This project, which was in a loss position, was significantly impacted by project charges associated with changes in estimates related to the availability of marine vessels during the six months ended June 30, 2013, as disclosed in Note 1—Use of Estimates. These decreases were partially offset by costs associated with marine activity on a newly awarded project in Brunei and fabrication activity on an existing EPCI project in Australia during the six months ended June 30, 2014.

Cost of operations in our Middle East segment decreased by $156.4 million, primarily due to the substantial completion of a pipelay project in the Caspian, an EPCI project in India and marine activity on an EPCI project in Saudi Arabia, each of which had higher activity during the six months ended June 30, 2013 as compared to the six months ended June 30, 2014. The EPCI project in Saudi Arabia was significantly influenced by increases in cost estimates of approximately $43.0 million during the six months ended June 30, 2013, due to an extended offshore hookup campaign. While the project recognized losses in the six months ended June 30, 2013, it remains in an overall profitable position. These declines were partly offset by increased activity on an EPCI project in Saudi Arabia.

Operating Income

Operating results improved $83.0 million to an operating loss of $13.6 million in the six months ended June 30, 2014 from an operating loss of $96.5 million in the six months ended June 30, 2013, primarily due to an improvement in our Middle East segment.

The Middle East segment operating results improved by $90.4 million. The improvement was primarily attributable to one of our EPCI projects in Saudi Arabia which was adversely impacted by changes in estimates of approximately $43.0 million during the six months ended June 30, 2013, due to an extended offshore hookup campaign. On a pipelay project in the Caspian, the operating income increased by $38.8 million, primarily due to increased revenue and reduced cost estimates of approximately $29.1 million based on

43

positive developments during the six months ended June 30, 2014 from the ongoing project closeout process with the customer. Increased marine activity on a project in Saudi Arabia during the six months ended June 30, 2014 contributed $6.4 million to the improvement. These increases were partly offset by deteriorations in another EPCI project in Saudi Arabia of $5.6 million, mainly due to changes in estimate of approximately $6.6 million.

The Asia Pacific segment operating results decreased by $49.1 million. The decrease was primarily due to an approximate $128.7 million decline in operating income from two of our EPCI projects in Australia and a marine installation project in Malaysia, which had significant marine activity in the six months ended June 30, 2013 and were completed during the year ended December 31, 2013. Contributing to the decrease was approximately $50 million of successful project close-out negotiations and resolution of pending change orders with our customer on one of the EPCI projects in Australia which occurred in the corresponding prior-year period. The decrease was also due to the completion of marine activity on a marine installation project in Malaysia and a reduction in fabrication activity on a project in Australia which had higher levels of activity in the six months ended June 30, 2013. These decreases were partially offset by the completion of a subsea project in Malaysia during the six months ended June 30, 2014. This project was significantly impacted by project charges associated with changes in estimates of approximately $66.0 million related to the availability of marine vessels during the six months ended June 30, 2013. During the six months ended June 30, 2014, this project also experienced positive changes in cost estimates of approximately $30.8 million, mainly due to productivity improvements on our marine vessels and offshore support activities and project close out-savings. Marine activity on a vessel charter project also partially offset the decline in operating income during the six months ended June 30, 2014.

The Americas segment recognized an operating loss of $20.7 million in the six months ended June 30, 2014, compared to an operating loss of $65.1 million in the six months ended June 30, 2013. This was primarily due to: net changes in estimates on four projects, partly offset by increased activity; gains on sales of assets; and a lower level of restructuring charges as compared to the corresponding prior year period.

On an EPCI project in Altamira, our operating income decreased by $56.4 million, primarily due to increases in costs estimates increases with changes in estimate on extended project management costs arising from expected project delays, projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases and the recognition of corresponding liquidated damages. This project is estimated to be completed in the fourth quarter of 2015. Americas segment operating income further decreased by $12.9 million due to increased cost estimates of $22.5 million relating to a subsea project in the U.S. Gulf of Mexico, as a result of equipment downtime issues on the NO 102, our primary vessel working on the project. This was partly offset by approximately $9.6 million from approved change orders on that project during the six months ended June 30, 2014. Further, completion of activity on a fabrication project in the Morgan City facility led to a decrease in operating income of approximately $7.2 million. This project had higher fabrication activity during the six months ended June 30, 2013 and was completed during the year ended December 31, 2013. These negative impacts were partially offset by an increase of approximately $34.1 million on an EPCI project in Brazil, mainly due to $33.7 million of project close-out improvements from marine cost reductions upon completion of activities and increased recoveries due to successful developments from the ongoing approval process for additional weather-related compensation. Operating income also increased by $14.5 million on a project in the U.S. Gulf of Mexico, where there was higher marine activity during the six months ended June 30, 2014 as compared to the corresponding period in the prior year.

Gain on asset sales included approximately $25.0 million from the sale of our Harbor Island facility near Corpus Christi, Texas and approximately $10.1 million from assets disposed from our Morgan city fabrication facility as a result of our decision to discontinue utilization of that facility.

Restructuring costs in the Americas segment decreased by $10.9 million during the six months ended June 30, 2014 as compared to the six months ended June 30, 2013.

Other Items in Operating Income

Selling, general and administrative expenses increased $7.4 million, primarily as a result of increased amortization of deferred non-cash benefit plan losses.

Gain on sale of assets for three months ended June 30, 2014 included the effect of cancellation of a pipelay system originally intended for the LV 108, which resulted in a $10.7 million improvement to the equipment cancellation cost estimate included in the $37.8 million of vessel impairment charges recognized during the quarter ended December 31, 2013.

Operating income was also impacted by a reduction in restructuring expense of approximately $8.1 million from $15.5 million in the six months ended June 30, 2013 to $7.4 million incurred in the six months ended June 30, 2014, as discussed above under “—Recent Developments—Americas and Corporate Restructuring.”

44

Equity in loss of unconsolidated affiliates changed by $7.4 million to a loss of $2.2 million in the six months ended June 30, 2014 as compared to a loss of $9.6 million in the six months ended June 30, 2013, primarily due to impairment of two investments in unconsolidated affiliates [CMO and Spars] during 2013, which had generated losses during the six months ended June 30, 2013, and improved results generated by our FloaTEC joint venture.

Other Items

Results for the six months ended June 30, 2014 were significantly impacted by interest expense from new financing arrangements as discussed below. The six-month period ended June 30, 2013 was not significantly impacted by interest expense.

Gain on foreign currency—net decreased by $3.8 million to income of $2.5 million in the six months ended June 30, 2014 from income of $6.4 million in the six months ended June 30, 2013, primarily due to foreign exchange losses of $1.7 million recognized during the 2014 period, as compared to foreign exchange gains of approximately $1.9 million recognized during the 2013 period.

Provision for Income Taxes

For the six months ended June 30, 2014, we recognized a loss before provision for income taxes of $50.3 million, compared to a loss of $88.6 million in the six months ended June 30, 2013. In the aggregate, the provision for income taxes was $8.3 million and $33.2 million for the six months ended June 30, 2014 and 2013, respectively.

We were able to utilize past losses in certain jurisdictions which were previously un-benefited to offset our improving income (primarily U.S., Saudi Arabia, Malaysia and Singapore). Accordingly, our provision for income taxes decreased.

Noncontrolling Interests

Net income attributable to noncontrolling interests decreased by $4.9 million to $2.2 million in the six months ended June 30, 2014 from $7.1 million in the six months ended June 30, 2013, primarily due to losses in our Malaysian subsidiary, Berlian McDermott Sdn. Bhd.

Backlog

Backlog represents the dollar amount of revenues we expect to recognize in the future from contracts awarded and those that are in progress. These amounts are presented in U.S. dollars and are based on terms that we have contractually agreed to with our customers. Currency risk associated with backlog contracts that is not mitigated within the contract is generally mitigated with the use of foreign currency derivative (hedging) instruments, when deemed significant. However, these actions may not eliminate all currency risk exposure included within our long-term contracts. Backlog is not a measure defined by generally accepted accounting principles and is not a measure of contract profitability. Our methodology for determining backlog may not be comparable to methodologies used by other companies in determining their backlog amounts. The backlog values we disclose include anticipated revenues associated with: (1) the original contract amounts; (2) change orders for which we have received written confirmations from the applicable customers; (3) change orders for which we expect to receive confirmations in the ordinary course of business; and (4) claims that we have made against our customers. We do not include expected revenues of contracts related to unconsolidated joint ventures in our backlog, except to the extent of any contract awards we may receive from those joint ventures.

We include unapproved change orders for which we expect to receive confirmations in the ordinary course of business in backlog, generally to the extent of the lesser of the amounts we expect to recover or the associated costs incurred. Any revenue that would represent profit associated with unapproved change orders is generally excluded from backlog until written confirmation is obtained from the applicable customer. However, consideration is given to our history with the customer as well as the contractual basis under which we may be operating. Accordingly, in certain cases based on our historical experience in resolving unapproved change orders with a customer, the associated profit may be included in backlog. The total unapproved change orders included in our estimates at completion aggregated approximately $296.5 million, of which approximately $43.8 million was included in backlog at June 30, 2014. If an unapproved change order is disputed or rejected by the customer, the associated amount of revenue is treated as a claim.

We include claims in backlog only when we have a legal basis to do so, consider collection to be probable and believe we can reliably estimate the ultimate value. Claims revenue is included in backlog to the extent of the lesser of the amounts we expect to recover or associated costs incurred. Total claims revenue included in backlog at June 30, 2014 and December 31, 2013 was approximately $0.2 million and $0.2 million, respectively. See Note 1 to our unaudited condensed consolidated financial statements included in this report for a discussion of claims revenue included in our estimates at completion as of June 30, 2104.

45

Backlog may not be indicative of future operating results, and projects in our backlog may be cancelled, modified or otherwise altered by customers. We can provide no assurance as to the profitability of our contracts reflected in backlog. It is possible that our estimates of profit could increase or decrease based on, among other things, changes in productivity, actual downtime and the resolution of change orders and claims with the customers.

Of the June 30, 2014 backlog amount of $4.1 billion, approximately $426.4 million relates to four active projects that are in loss positions, whereby future revenues are expected to be equal to costs when recognized. Included in this amount is $169.7 million of backlog associated with an EPCI project in Altamira, which is expected to be completed in the fourth quarter of 2015, $133.0 million pertaining to a five-year charter of the Agile in Brazil, which began in early 2012, and $33.1 million relating to a subsea project in the U.S. Gulf of Mexico scheduled for completion during 2014, all of which are being conducted by our Americas segment. The amount also includes $90.6 million of backlog relating to an EPCI project in Saudi Arabia, in our Middle East segment, which is expected to be completed by early 2016.

The following table summarizes changes to our backlog (in thousands):

Backlog at December 31, 2013	$	5,067,164
Bookings from new awards		174,743

Liquidity and Capital Resources

Our primary sources of liquidity are cash flows generated from operations and cash and cash equivalents at June 30, 2014. Management believes that our cash flows from operations and the sources of liquidity and capital resources described below will be sufficient to fund our liquidity requirements for at least the next twelve months.

Former Credit Agreement

The Former Credit Agreement provided for revolving credit borrowings and issuances of letters of credit in an aggregate outstanding amount of up to $950.0 million. Proceeds from borrowings under the Former Credit Agreement were available for working capital needs and other general corporate purposes. At December 31, 2013, there were no borrowings outstanding, and letters of credit issued under the Former Credit Agreement totaled $214.3 million. At December 31, 2013, there was $735.7 million available for borrowings or to meet letter of credit requirements under the Former Credit Agreement. During the year ended December 31, 2013, our outstanding borrowings under the Former Credit Agreement did not exceed $80.0 million, and we had average outstanding borrowings under the Former Credit Agreement of approximately $23.5 million, with an average interest rate of 2.28%. In addition, at December 31, 2013, we had $96.9 million in outstanding unsecured bilateral letters of credit. At March 31, 2014, there was $250.0 million of revolving credit borrowings outstanding under the Former Credit Agreement, all of which were repaid during April 2014.

46

New Credit Facilities

The indebtedness and other obligations under the New Credit Agreement are guaranteed by substantially all of our material, wholly owned subsidiaries, other than our captive insurance subsidiary (collectively, the “Guarantors”). In connection with the New Credit Agreement, we paid certain fees to the lenders thereunder, as well as certain arrangement fees to the arrangers and agents for the New Credit Agreement, which we have capitalized and are amortizing to interest expense over the respective terms of the LC Facility and the Term Loan. We also paid certain fees to the initial purchasers of the senior secured notes and to the underwriter of the tangible equity units referred to below, which we have capitalized and are amortizing to interest expense over the respective terms of the related indebtedness.

LC Facility

The LC Facility provides for an initial letter of credit capacity of $400.0 million and allows for uncommitted increases in capacity of $100.0 million through December 31, 2014 and an additional $100.0 million thereafter, potentially increasing the total capacity to $600.0 million through the term of the LC Facility. Letters of credit issuable under the LC Facility support the obligations of McDermott and its affiliates and joint ventures. The aggregate amount of the LC Facility available for financial letters of credit is capped at 25% of the total LC Facility. As of June 30, 2014, letters of credit issued under the LC Facility totaled $225.3 million, including financial letters of credit of $3.2 million.

The LC Facility is secured on a first-lien, first-out basis (with relative priority over the Term Loan) by pledges of the capital stock of all the Guarantors and mortgages on, or other security interests in, substantially all the tangible and intangible assets of our company and the Guarantors, subject to specific exceptions.

The LC Facility contains various customary affirmative covenants, as well as specific affirmative covenants, including specific reporting requirements and a requirement for ongoing periodic financial reviews by a financial advisor. The LC Facility also requires compliance with various negative covenants, including limitations with respect to the incurrence of other indebtedness and liens, restrictions on acquisitions, capital expenditures and other investments, restrictions on sale/leaseback transactions and restrictions on prepayments of other indebtedness.

The LC Facility requires us to generate consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) of at least certain specified amounts over the term of the facility. The LC Facility also requires us to maintain a ratio of fair market value of vessel collateral to the sum of (1) the outstanding principal amount of the Term Loan, (2) the aggregate amount of undrawn financial letters of credit outstanding under the LC Facility, (3) all drawn but unreimbursed letters of credit under the LC Facility, and (4) mark-to-market foreign exchange exposure that is not cash secured of at least 1.20:1.00. The LC Facility also specifies maximum capital expenditures over the term of the facility and requires us to maintain at least $200.0 million of minimum available cash, at the end of each quarter. We were in compliance with the covenants under the LC Facility as of June 30, 2014.

The LC Facility provides for a commitment fee of 0.50% per year on the unused portion of the LC Facility and letter of credit fees at an annual rate of 2.25% for performance letters of credit and 4.50% for financial letters of credit, as well as customary issuance fees and other fees and expenses.

In addition, the LC Facility permits us to deposit up to $300.0 million with letter of credit issuers to cash collateralize letters of credit. As of June 30, 2014, we had approximately $163.4 million of letters of credit supported by cash collateral that was included in restricted cash and cash equivalents.

Term Loan

The Term Loan is secured on a first-lien, second-out basis (with the LC Facility having relative priority over the Term Loan) by pledges of the capital stock of all the Guarantors and mortgages on, or other security interests in, substantially all tangible and intangible assets of our company and the Guarantors, subject to specific exceptions. At June 30, 2014, there was $300.0 million in borrowings outstanding under the Term Loan agreement, of which $3.0 million was classified as current notes payable.

The Term Loan requires mandatory prepayments from: (1) the proceeds from the sale of assets, as well as insurance proceeds, in each case subject to certain exceptions, to the extent such proceeds are not reinvested in our business within 365 days of receipt; (2) net cash proceeds from the incurrence of indebtedness not otherwise permitted under the New Credit Agreement; and (3) 50% of amounts deemed to be “excess cash flow,” subject to specified adjustments. The Term Loan also requires quarterly amortization payments equal to $750,000. The Term Loan also provides for a prepayment premium if we prepay or re-price the Term Loan prior to April 16, 2015.

47

The Term Loan requires compliance with various customary affirmative and negative covenants. We must also maintain a ratio of “ownership adjusted fair market value” of marine vessels to the sum of (1) the outstanding principal amount of the Term Loan and (2) the aggregate principal amount of unreimbursed drawings and advances under the LC Facility of at least 1.75:1.00. As of June 30, 2014, we were in compliance with all the covenants under the Term Loan.

The Term Loan was incurred with 25 basis points of original issue discount and bears interest at a floating rate, which can be, at our option, either: (1) a LIBOR rate for a specified interest period (subject to a LIBOR “floor” of 1.00%) plus an applicable margin of 4.25%; or (2) an alternate base rate (subject to a base rate “floor” of 2.00%) plus an applicable margin of 3.25%.

Senior Notes

During April 2014 we issued $500.0 million in aggregate principal amount of 8.000% senior secured notes due 2021 (the “Notes”) in a private placement in accordance with Rule 144A and Regulation S under the Securities Act of 1933, as amended. Interest on the Notes is payable semi-annually in arrears on May 1 and November 1 of each year, beginning on November 1, 2014, at an annual rate of 8%. The Notes are scheduled to mature on May 1, 2021. As of June 30, 2014, there was $500.0 million of Senior Notes outstanding.

The Notes are unconditionally guaranteed on a senior secured basis by the Guarantors, and the Notes are secured on a second—lien basis by pledges of capital stock of certain of our subsidiaries and mortgages and other security interests covering (1) specified marine vessels owned by certain of the Guarantors and (2) substantially all the other tangible and intangible assets of our company and the Guarantors, subject to exceptions for certain assets.

At any time or from time to time on or after May 1, 2017, at our option, we may redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, together with accrued and unpaid interest to the redemption date, if redeemed during the 12-month period beginning May 1 of the years indicated:

Year	Percentage
2017		104	%
2018		102	%
2019 and thereafter		100	%

The Indenture governing the Notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to: (1) incur or guarantee additional indebtedness or issue preferred stock; (2) make investments or certain other restricted payments; (3) pay dividends or distributions on capital stock or purchase or redeem subordinated indebtedness; (4) sell assets; (5) create restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us; (6) create certain liens; (7) sell all or substantially all of our assets or merge or consolidate with or into other companies; (8) enter into transactions with affiliates; and (9) create unrestricted subsidiaries. Many of those covenants would become suspended if the Notes were to attain an investment grade rating from both Moody’s Investors Service, Inc. and Standard and Poor’s Ratings Services and no default has occurred. The covenants mentioned above are subject to a number of important exceptions and limitations.

Tangible Equity Units

During April 2014, we issued 11,500,000 6.25% tangible equity units (“Units”), each with a stated amount of $25.00. Each Unit consists of (1) a prepaid common stock purchase contract and (2) a senior amortizing note due April 1, 2017 (each an “Amortizing Note”) that has an initial principal amount of $4.1266 per Amortizing Note, bears interest at a rate of 7.75% per annum and has a final scheduled installment payment date of April 1, 2017.

The prepaid common stock purchase contracts were accounted for as additional paid-in capital totaling $240.0 million. The Amortizing Notes were recorded as long-term debt totaling $47.5 million, of which $14.5 million was classified as current notes payable.

Each prepaid common stock purchase contract will automatically settle on April 1, 2017, unless settled earlier: (1) at the holder’s option, upon which we will deliver shares of our common stock, based on the applicable settlement rate and applicable market value of our stock as determined under the purchase contract; or (2) at our option, upon which we will deliver shares of our common stock, based upon the stated maximum settlement rate of 3.5562 shares per Unit, subject to adjustment. Potential dilutive common shares for the settlement of the common stock purchase contracts totaled 40.9 million at June 30, 2014, based on that maximum number of shares issuable per Unit. The potential minimum number of shares issuable is 33.4 million, which represents 2.9030 per Unit. The maximum and minimum settlement rates for the Units are subject to adjustment for certain dilutive events.

North Ocean Financing

North Ocean 105

On September 30, 2010, MII, as guarantor, and North Ocean 105 AS, in which we have a 75% ownership interest, as borrower, entered into a financing agreement to finance a portion of the construction costs of the North Ocean 105. The agreement provides for borrowings of up to $69.4 million, bearing interest at 2.76% per year, and requires principal repayment in 17 consecutive semi-annual installments, which commenced on October 1, 2012. Borrowings under the agreement are secured by, among other things, a pledge of all of the equity of North Ocean 105 AS, a mortgage on the North Ocean 105, and a lien on substantially all of the other assets of North Ocean 105 AS. MII unconditionally guaranteed all amounts to be borrowed under the agreement. As of June 30, 2014 and December 31, 2103, there was $53.1 million and $57.2 million, respectively, in borrowings outstanding under this agreement, of which (as of each date) approximately $8.2 million was classified as current notes payable.

North Ocean 102

In December 2009, J. Ray McDermott, S.A. (“JRMSA”), a wholly owned subsidiary of MII, entered into a vessel-owning joint venture transaction with Oceanteam ASA. JRMSA has guaranteed approximately 50% of this debt based on its ownership percentages in the vessel-owning companies. The outstanding debt bore interest at a rate equal to the three-month LIBOR (which was subject to reset every three months) plus a margin of 3.315%. JRMSA paid in full the approximately $31.4 million notes payable balance upon maturity during January 2014. JRMSA expects to exercise its option to purchase Oceanteam ASA’s 50% ownership interest in the vessel-owing companies in December 2014. As of December 31, 2013 we reported a consolidated notes payable of $31.4 million on our consolidated balance sheet, all of which was classified as current notes payable and paid in full in early 2014.

Unsecured Bilateral Letters of Credit and Bank Guarantees

In 2012, McDermott Middle East, Inc, and MII executed a general reimbursement agreement in favor of a bank located in the UAE relating to issuances of bank guarantees in support of contracting activities in the Middle East and India. As of June 30, 2014 and December 31, 2013, bank guarantees issued under these arrangements totaled $50.4 million and $55.8 million, respectively. In 2007 and in 2012, JRMSA and MII executed general unsecured reimbursement agreements in favor of three institutions that were lenders under the Former Credit Agreement relating to issuances of letters of credit in support of contracting activities, primarily in Asia and the Middle East. Letters of credit issued under two of these arrangements have either been replaced by letters of credit under the LC Facility or cash collateralized. The letters of credit issued under these arrangements totaled $12.0 million and $39.8 million as of June 30, 2014 and December 31, 2013, respectively.

On April 20, 2012, McDermott and one of its wholly owned subsidiaries, McDermott Australia Pty. Ltd. (“McDermott Australia”), entered into a secured Letter of Credit Reimbursement Agreement (the “Reimbursement Agreement”) with Australia and New Zealand Banking Group Limited (“ANZ”). In accordance with the terms of the Reimbursement Agreement, ANZ issued letters of credit in the aggregate amount of approximately $109.0 million to support McDermott Australia’s performance obligations under contractual arrangements relating to a field development project. The obligations of McDermott and McDermott Australia under the Reimbursement Agreement are secured by McDermott Australia’s interest in the contractual arrangements and certain related assets. During six months ended June 30, 2014, we replaced these letters of credit with letters of credit under the LC Facility.

Surety Bonds

In 2012 and 2011, MII executed general agreements of indemnity in favor of surety underwriters based in Mexico relating to surety bonds issued in support of contracting activities of J. Ray McDermott de Mèxico, S.A. de C.V. and McDermott, Inc, both subsidiaries of MII. As of June 30, 2014 and December 31, 2013, bonds issued under these arrangements totaled $42.1 million and $43.5 million, respectively. In October 2013, MII executed general agreements of indemnity in favor of surety underwriters relating to surety bonds in support of vessels operating in Brazil. The project requiring these bonds was completed during the quarter allowing us to cancel the outstanding bonds. Accordingly, as of June 30, 2014, there were no bonds issued under these arrangements. As of December 31, 2103, the bonds issued under these arrangements totaled $106.3 million.

Cash, Cash Equivalents and Investments

In the aggregate, our cash and cash equivalents, restricted cash and investments increased by $802.2 million to $958.1 million as of June 30, 2014 from $155.9 million as of December 31, 2013, primarily due to the financing transaction discussed in recent developments.

49

As of June 30, 2014, we had current restricted cash and cash equivalents totaling $189.9 million compared to $23.7 million as of December 31, 2013, due to cash collateral for letters of credit which at our discretion may be replaced with letters of credit under LC Facility.

As of June 30, 2014, we had investments with a fair value of $4.2 million. Our investment portfolio consists of commercial paper and mutual funds. Our investments are classified as available for sale and are carried at fair value with unrealized gains and losses, net of tax, reported as a component of other comprehensive income (loss). Our net unrealized gain on investments was $0.2 million at June 30, 2014. During the year ended December 31, 2013, we recognized other than temporary impairment of $1.6 million on the asset-backed securities and collateralized mortgage obligations. Our net unrealized gain on investments was $0.2 million as of December 31, 2013.

Our current assets, less current liabilities, excluding cash and cash equivalents and current restricted cash, improved by $34.5 million to a negative $148.6 million at June 30, 2014 from a negative $183.1 million at December 31, 2013, primarily due to the decreases in short-term notes payables and accounts payable.

Contracts in Progress and Advanced Billings on Contracts

Our net contracts in progress and advanced billings on contracts increased by $88.7 million to $235.8 million as of June 30, 2014 from $147.1 million as of December 31, 2013.

Cash Flow Activities

Operating activities. Our net cash used in operating activities was $92.9 million in the six months ended June, 2014, which was very consistent with $96.5 million in the six months ended June 30, 2013.

Investing activities. Our net cash used in investing activities was $263.2 million in the six months ended June 30, 2014, compared to cash used in investing activities of $96.7 million in the six months ended June 30, 2013. This change was primarily attributable to an increase in restricted cash and cash equivalents related to the new financing arrangements discussed above.

Financing activities. Our net cash provided by financing activities was $1,001.3 million in the six months ended June 30, 2014 as compared to net cash used in financing activities of $19.4 million in the six months ended June 30, 2013. The change was primarily attributable to the financing transactions discussed in “—Recent Developments,” above.

Capital Expenditures

As part of our strategic growth program, our management regularly evaluates our marine vessel fleet to ensure our fleet capability is adequately aligned with our overall growth strategy. These assessments may result in capital expenditures to upgrade, acquire or operate vessels that would enhance or grow our technical capabilities, or may involve engaging in discussions to dispose of certain marine vessels.

Capital expenditures for the six months ended June 30, 2014 were $155.0 million, as compared to $144.5 million for the six months ended June 30, 2013. Capital expenditures for the six months ended June 30, 2014 were primarily attributable to the construction of the LV 108, the Deepwater Lay Vessel 2000 (“DLV 2000”), and the continued development of our Altamira Mexico fabrication facility, as well as costs associated with upgrading the capabilities of other marine vessels. Capital expenditures for the six months ended June 30, 2013 were primarily attributable to the construction of the LV 108 and upgrades to the NO 105 and DB 32, as well as costs associated with upgrading the capabilities of other marine vessels, including related equipment.

Based on our expectations relating to the demand in the deepwater market, in December 2012, we entered into a contract to construct the DLV 2000. Like the LV 108, the DLV 2000 is designed for advanced deepwater subsea and marine construction operations. Prior to December 31, 2015, we expect to incur capital expenditures ranging from approximately $375.0 million to $425.0 million associated with the construction of the LV 108 and DLV 2000, including related equipment.

Derivative Contracts

We previously entered into derivative contracts to mitigate currency exchange movements primarily associated with certain firm purchase commitments and various foreign currency expenditures we expect to incur on one of our Asia Pacific segment’s EPCI projects through 2017. While we currently believe that these contracts will be effective in mitigating the associated currency exchange risks, it is possible that changes in the project may cause reduced effectiveness of these derivative contracts. Therefore, we may experience larger gains or losses on foreign currency movements due to the ineffective portion or the portion excluded from the assessment of effectiveness of these and other derivative contracts.

50

At June 30, 2014, our derivative financial instruments consisted primarily of foreign currency forward contracts. The notional value of our outstanding derivative contracts totaled approximately $1.0 billion at June 30, 2014, with maturities extending through 2017. Of this amount, approximately $735.0 million is associated with various foreign currency expenditures we expect to incur on the Asia Pacific segment EPCI project.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

In the normal course of business, our results of operations are exposed to certain market risks, primarily associated with fluctuations in currency exchange rates and interest rate risk. Our exposure to market risk from changes in interest rates relates primarily to our Term Loan, cash equivalents and our investment portfolio, which primarily consists of investments in commercial paper and other highly liquid money market instruments denominated in U.S. dollars. We are averse to principal loss and seek to ensure the safety and preservation of our invested funds by limiting default risk, market risk and reinvestment risk. All of our investments in debt securities are classified as available-for-sale.

We have operations in many locations around the world, and, as a result, our financial results could be significantly affected by factors such as changes in currency exchange rates or weak economic conditions in foreign markets. In order to manage the risks associated with currency exchange rate fluctuations, we attempt to hedge those risks with foreign currency derivative instruments. Historically, we have hedged those risks with foreign currency forward contracts. In certain cases, contracts with our customers may contain provisions under which payments from our customers are denominated in U.S. Dollars and in a foreign currency. The payments denominated in a foreign currency are designed to compensate us for costs that we expect to incur in such foreign currency. In these cases, we may use derivative instruments to reduce the risks associated with currency exchange rate fluctuations arising from differences in timing of our foreign currency cash inflows and outflows. Our operational cash flows and cash balances, though predominately held in U.S. dollars, may consist of different currencies at various points in time in order to execute our project contracts globally. Non-U.S. denominated asset and liability balances are subject to currency fluctuations when measured period to period for financial reporting purposes in U.S. dollars.

We have exposure to changes in interest rates under our Term Loan (see Item 2—“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources”). As of June 30, 2014, we had no material future earnings or cash flow exposures from changes in interest rates on our other outstanding debt obligations, as substantially all of these obligations had fixed interest rates.

Our operational cash flows and cash balances, though predominately held in U.S. dollars, may consist of different currencies at various points in time in order to execute our project contracts globally. Non-U.S. denominated asset and liability balances are subject to currency fluctuations when measured period to period for financial reporting purposes in U.S. dollars.

Currency Exchange Rate Sensitivity

The following table provides information about our foreign currency forward contracts outstanding at June 30, 2014 and presents such information in U.S. dollar equivalents. The table presents notional amounts and related weighted-average exchange rates by expected (contractual) maturity dates and constitutes a forward-looking statement. These notional amounts generally are used to calculate the contractual payments to be exchanged under the contract. The average contractual exchange rates are expressed using market convention, which is dependent on the currencies being bought and sold under the forward contract.

Item 4. Controls and Procedures

As of the end of the period covered by this quarterly report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) adopted by the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Our disclosure controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. You should note that the design of any system of disclosure controls and procedures is based in part upon various assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. Based on the evaluation referred to above, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures are effective as of June 30, 2014 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and such information is accumulated and communicated to management, including our principal executive and principal financial officers or persons performing similar functions, as appropriate to allow timely decisions regarding disclosure. There has been no change in our internal control over financial reporting during the quarter ended June 30, 2014 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

For information regarding ongoing investigations and litigation, see Note 10 to our unaudited condensed consolidated financial statements in Part I of this report, which we incorporate by reference into this Item.

Item 1A. Risk Factors

The following discussion updates the risk factor disclosure in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013.

Our debt and funded debt levels have increased significantly as a result of our recently completed refinancing transactions.

Our debt and funded debt obligations have increased significantly as a result of our recently completed financing transactions. Our significant debt and funded debt levels and related debt service obligations could have negative consequences, including:

• requiring us to dedicate significant cash flow from operations to the payment of principal, interest and other amounts payable on our debt, which would reduce the funds we have available for other purposes, such as working capital, capital expenditures and acquisitions;

• making it more difficult or expensive for us to obtain any necessary future financing for working capital, capital expenditures, debt service requirements, debt refinancing, acquisitions or other purposes;

• reducing our flexibility in planning for or reacting to changes in our industry and market conditions;

• making us more vulnerable in the event of a downturn in our business; and

• exposing us to increased interest rate risk given that a portion of our debt obligations are at variable interest rates.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

The following table provides information on our purchases of equity securities during the quarter ended June 30, 2014, all of which involved repurchases of shares of MII common stock in connection with the vesting of restricted stock units pursuant to the provisions of employee benefit plans that permit the repurchase of common stock to satisfy statutory tax withholding obligations associated with the vesting of restricted stock units:

Period	Total number of shares purchased		Average price paid per share		Total number of shares purchased as part of publicly announced plans or programs		Maximum number of shares that may yet be purchased under the plans or programs
April 1—April 30, 2014		290	$	7.03		not applicable		not applicable
May 1—May 31, 2014		11,372		7.07		not applicable		not applicable
June 1—June 30, 2014		72,437		7.96		not applicable		not applicable
Total		84,099	$	7.60		not applicable		not applicable

Item 5. Other Information.

On August 1, 2014, the Board of Directors of McDermott (the “Board”) approved an amendment to and restatement of the Company’s Amended and Restated By-Laws (as amended, the “By-Laws”). The By-Laws were amended to clarify that, in the election of any director, any shares for which votes are withheld shall not be considered as actually voting on such matter. This clarification was made in connection with a corresponding clarifying amendment made to the director resignation policy contained in McDermott’s Corporate Governance Guidelines (the “Guidelines”). As amended, the Guidelines provide that, in determining whether an incumbent director received a majority vote of the shares present or represented by proxy and entitled to vote, shares for which votes are withheld shall be taken into account to determine the required majority.

A special meeting of the stockholders may be held at any time upon the call of the Chairman of the Board of Directors of the Company (the “Chairman”), the Chief Executive Officer of the Company (the “Chief Executive Officer”) or by order of the Board of Directors of the Company (the “Board of Directors”).

Section 4. As determined on the record date fixed by the Board of Directors in accordance with the Articles of Incorporation, holders of a majority of the voting power of the shares of the outstanding capital stock of the Company entitled to vote, whether present in person or represented by proxy, shall constitute a quorum for the transaction of all business at any meeting of the stockholders. Any shares subject to “broker non-votes” shall be considered present at the meeting with respect to the determination of a quorum.

Section 5. In all matters arising at stockholders’ meetings, a majority of the voting power of the shares of outstanding capital stock of the Company present in person or represented by proxy at the meeting and entitled to vote and actually voting on the matter shall be necessary and sufficient for the election of directors or the transaction of any other business, except where some larger percentage is affirmatively required by applicable law or by the Articles of Incorporation. Any shares (i) for which votes are withheld in the election of any director or (ii) subject to “broker non-votes” (as defined by the rules of the New York Stock Exchange) with respect to any matter voted on at any such meeting shall not, in either case, be considered as actually voting on such matter.

At any annual meeting of the stockholders, only such business shall be conducted as shall have been brought before the meeting (a) by or at the direction of the Board of Directors, or (b) by any stockholder of the Company of record at the time of giving of the notice provided for in this Section, provided such stockholder is entitled to vote at such meeting and complies with the notice procedures set forth in this Section. For business to be properly brought before an annual meeting of the stockholders by a stockholder, the stockholder must have given timely notice thereof in writing to the Secretary of the Company. To be timely, a stockholder’s notice must be addressed to the attention of the Secretary and delivered to or mailed and received at the principal executive offices of the Company in Houston, Texas not less than 120 days nor more than 180 days prior to the first anniversary of the preceding year’s annual meeting of stockholders; provided, however, that if the date of the annual meeting is advanced more than 30 days prior to or delayed by more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the 180^th day prior to such annual meeting and not later than the close of business on the later of the 120^th day prior to such annual meeting or the 10^th day following the day on which public announcement of the date of such meeting is first made by the Company.

The stockholder’s notice shall set forth (i) the name and address of the stockholder proposing such business and of the beneficial owner, if any, on whose behalf the proposal or nomination is made; (ii) a representation that the stockholder is entitled to vote at such meeting

and a statement of the number of shares of the Company which are owned by the stockholder and the number of shares which are beneficially owned by the beneficial owner, if any; (iii) a representation that the stockholder intends to appear in person or by proxy at the meeting to nominate the person or persons or to propose the business specified in the notice; and (iv) as to each person the stockholder proposes to nominate for election or re-election as a director, the name and address of such person and such other information regarding such nominee as would be required in a proxy statement filed pursuant to the rules of the U.S. Securities and Exchange Commission had such nominee been nominated by the Board of Directors, and a description of any arrangements or understandings between the stockholder and such nominee and any other persons (including their names), pursuant to which the nomination is to be made, and the written consent of each such nominee to being named in the Company’s proxy statement as a nominee and to serve as a director if elected (in the event a determination is made by the Company to name such nominee in such proxy statement); or, as to each matter the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting, and any material interest of the stockholder in such business. Unless otherwise required by applicable law, the chairman of the meeting may refuse to permit any business to be brought before an annual meeting by a stockholder not in compliance with the provisions of this Section or if such stockholder fails to appear in person or by proxy at the meeting, notwithstanding that proxies in respect of a vote on such business may have been received by the Company. Notwithstanding the foregoing provisions of this Section, a stockholder shall also comply with all applicable requirements of the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, and with all other applicable laws, rules and regulations, with respect to the matters set forth in this Section.

Section 2. Meetings of the Board of Directors may be called by the Chairman or by the Chief Executive Officer or by a majority of the directors by giving notice to each director. Members of the Board may hold and participate in any meeting of the Board of Directors by means of conference telephone or other communications equipment that permits all persons participating in the meeting to hear each other, and participation of any Director in a meeting through such means will constitute the presence in person of that Director at that meeting.

Section 3. Meetings of the Board of Directors shall be presided over by the Chairman, or if the Chairman so requests or is absent or unable to preside, by the Lead Director; if neither the Chairman nor the Lead Director is present and able to preside, then by the Chief Executive Officer, or if the Chief Executive Officer so requests or is absent or unable to preside, by the President; if none of the above is present and able to preside, then one of the Directors shall be elected at the meeting to preside over same.

Section 4. Whether or not a quorum is present at any meeting of the Board of Directors, a majority of the directors present may adjourn the meeting from time to time as they may determine. Notice need not be given of the reconvening of any such adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. Any business may be transacted at the reconvened meeting which might have been transacted at the original meeting.

Section 5. The presence in person (or by conference telephone or other communications equipment) of a majority of the total number of directors then in office will constitute a quorum for the transaction of business at any meeting of the Board of Directors. Except in cases in which the Articles of Incorporation or these By-Laws otherwise provide, the vote of a majority of the directors present (including by conference telephone or other communications equipment) at a meeting at which a quorum is present will be the act of the Board.

Section 6. The Board of Directors may, without a meeting, prior notice or a vote, take any action it must or may take at any meeting, if all members of the Board consent thereto in writing or electronic transmission, and the written consents or electronic transmissions are filed with the minutes of proceedings of the Board of Directors kept by the Secretary.

Each such committee shall meet at stated times or on notice to all by any of its own number. It shall fix its own rules of procedure in accordance with the Company’s Corporate Governance Guidelines and the respective committee’s charter. In the absence or disqualification of any member of such a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or she or they constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member, to the extent not inconsistent with the Company’s Corporate Governance Guidelines. A majority of the members of any such committee shall constitute a quorum and the affirmative vote of a majority of those committee members present at a meeting at which a quorum is present shall be the act of such committee. Each such committee shall cause minutes of its proceedings to be kept. Members of any such committee may hold and participate in any meeting of such

7

committee by means of conference telephone or other communications equipment that permits all persons participating in the meeting to hear each other, and participation of any committee member in a meeting through such means will constitute the presence in person of that committee member at that meeting. Any such committee may, without a meeting, prior notice or a vote, take any action it must or may take at any meeting, if all members of such committee consent thereto in writing or electronic transmission, and the written consents or electronic transmissions are filed with the minutes of proceedings of such committee kept by the Secretary.

Section 8. Directors shall receive as compensation for their services an amount in addition to actual expenses incident to the attending of meetings to be fixed by resolution of the Board of Directors. Nothing in this section shall be construed to preclude a Director from serving the Company in any other capacity and receiving compensation therefore.

Section 9. No person shall be nominated to stand for election or re-election to the Company’s Board of Directors if such person will have attained the age of 72 prior to the date of election or re-election.

8

during the period of such disability, such Director shall be precluded from acting in any manner with respect to any such plan.

ARTICLE VI

Indemnification

Section 1. Each person (and the heirs, executors and administrators of such person) who is or was a director and/or officer of the Company, whether elected or appointed (each such person being an “Indemnitee”), shall in accordance with Section 2 of this Article VI be indemnified and held harmless by the Company to the fullest extent permitted by applicable law in effect on the date of amendment and restatement of these By-Laws, and to such greater extent as applicable law may thereafter permit, including against any and all losses, liabilities, costs, damages and reasonable expenses that may be paid or incurred by such Indemnitee in connection with or resulting from any actual or threatened claim, action, suit or proceeding (whether brought by or in the right of the Company or otherwise), civil, criminal, administrative or investigative, or in connection with an appeal relating thereto, in which such Indemnitee may

11

become involved, as a party or otherwise, by reason of such Indemnitee being or having been a director or officer of the Company or, if such Indemnitee shall be serving or shall have served in such capacity at the request of the Company, as a director, officer, employee or agent of another corporation or any partnership, joint venture, trust or other entity whether or not such Indemnitee continues to be such at the time such liability or expense shall have been paid or incurred, provided such Indemnitee acted, in good faith, in a manner he or she reasonably believed to be in or not opposed to the best interest of the Company and in addition, in criminal actions or proceedings, had no reasonable cause to believe that his or her conduct was unlawful. As used in this ARTICLE VI, the terms, “liability” and “expense” shall include, but shall not be limited to, counsel fees and disbursements and amounts of judgments, fines or penalties against, and amounts paid in settlement by, such director or officer. The termination of any actual or threatened claim, action, suit or proceeding, civil, criminal, administrative, or investigative, by judgment, settlement (whether with or without court approval), conviction or upon a plea of guilty or nolo contendere, or its equivalent, shall not create a presumption that such Indemnitee did not meet the standards of conduct set forth in this Section 1.

Section 2. Every Indemnitee shall be entitled to indemnification under Section 1 of this ARTICLE VI with respect to any claim, action, suit or proceeding of the character described in such Section 1 in which he or she may become in any way involved as set forth in such Section 1, if (i) he or she has been wholly successful on the merits or otherwise in respect thereof, or (ii) the Board of Directors acting by a majority vote of a quorum consisting of directors who are not parties to (or who have been wholly successful with respect to) such claim, action, suit or proceeding, finds that such Indemnitee has met the standards of conduct set forth in such Section 1 with respect thereto, or (iii) a court determines that he or she has met such standards with respect thereto, or (iv) independent legal counsel (who may be the regular counsel of the Company) deliver to the Company their written advice that, in their opinion, he or she has met such standards with respect thereto.

12

Section 3. For every such Indemnitee who has become or been threatened to become, a party to any actual or threatened claim, action, suit or proceeding of any kind that might give right to such Indemnitee to indemnification under Section 1 of this Article VI (each, a “Matter”), the Company will advance all expenses reasonably incurred by or on behalf of that Indemnitee in connection with that Matter, provided that that Indemnitee shall have delivered an undertaking by or on behalf of that person to repay to the Company any expenses so advanced if it is ultimately determined that that Indemnitee is not entitled to be indemnified by the Company under that Section 1 in respect of those expenses. The Company will accept any such undertaking of any such Indemnitee without regard to the financial ability of such Indemnitee to make such payment. Notwithstanding the foregoing, this Section 3 will not require the Company to advance expenses with respect to any Matter initiated by or on behalf of any such Indemnitee against the Company or any of its subsidiaries, whether as an initial action or by counter or similar claim, without the prior approval of the Board of Directors. The provisions of this Section 3 shall inure to the benefit of the heirs, executors and administrators of any person entitled to the benefits of this Section 3. No amendment to this Section 3, directly or by amendment to any other provision of these By-Laws, shall have any retroactive effect with respect to any Matter arising from or based on any act or omission to act by any person which occurs prior to the effectiveness of that amendment.

Section 4. The Company, by adoption of a resolution of the Board of Directors, may indemnify and advance expenses to a person who is an employee, agent or fiduciary of the Company including any such person who is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of any other corporation or any partnership, joint venture, trust or other entity to the same extent and subject to the same conditions under which it may indemnity and advance expenses to an Indemnitee under this ARTICLE VI.

13

Section 5. The rights of indemnification under this ARTICLE VI shall be in addition to any rights to which any such Indemnitee may otherwise be entitled by contract or as a matter of law.

Section 6. If any provision or provisions of this ARTICLE VI shall be held to be invalid, illegal or unenforceable for any reason whatsoever, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby; and, to the fullest extent possible, the provisions of this ARTICLE VI shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

ACQUISITION AND DISPOSITIONS

Discontinued Operations And Disposal Groups [Abstract]

ACQUISITION AND DISPOSITIONS

NOTE 2—ACQUISITION AND DISPOSITIONS

Acquisition

During the quarter ended March 31, 2013, we entered into a share purchase agreement to acquire all of the issued and outstanding shares of capital stock of Deepsea Group Limited, a United Kingdom-based company that provides subsea and other engineering services to international energy companies, primarily through offices in the United Kingdom and the United States. Total consideration was approximately $9.0 million, which includes cash ($6.0 million) and the delivery of 313,580 restricted shares of MII common stock (out of treasury). The transaction was accounted for using the acquisition method and, accordingly, assets acquired and liabilities assumed were recorded at their respective fair values.

During the quarter ended December 31, 2013, we entered into two joint ventures with TH Heavy Engineering Berhad (“THHE”), whereby we acquired a 30% interest in a subsidiary of THHE, THHE Fabricators Sdn. Bhd., and THHE acquired a 30% interest in our Malaysian subsidiary, Berlian McDermott Sdn. Bhd. Accounting for these transactions is preliminary at June 30, 2014 and is pending finalization of these transactions by the end of 2014. As of June 30, 2014, we recorded an equity method investment of approximately $25.5 million, a non-controlling interest of approximately $20.9 million and an increase in capital in excess of par value of approximately $4.6 million arising from these transactions.

Non-Core Asset Sales

We previously committed to a plan to sell four of our multi-function marine vessels, specifically the Bold Endurance, DB 16, DB 26 and the DLB KP1. Assets classified as held for sale are no longer depreciated. During the six months ended June 30, 2014, we completed the sale of the DLB KP1 for aggregate cash proceeds of approximately $8.4 million, resulting in a gain of approximately $6.4 million recognized in our Middle East segment. During the six months ended June 30, 2013 we completed the sale of the Bold Endurance and the DB 26 for aggregate cash proceeds of approximately $32.0 million, resulting in an aggregate gain of approximately $12.5 million. We remain in discussions with interested parties to sell the DB 16.

In April 2014, we completed the sale of our Harbor Island facility near Corpus Christi, Texas for proceeds of approximately $31.7 million and a gain of approximately $25.0 million, which has been recognized in our Americas segment.

In June 2014, as part of our plan to discontinue utilization of Morgan City facility we disposed of several assets, including certain equipment, for aggregate cash proceeds of approximately $13.6 million, resulting in an aggregate gain of approximately $11.4 million, of which approximately $1.3 million was recorded in connection with our Americas restructuring, discussed below. This portion of the gain pertained to impairments previously recorded in the period ended June 30, 2013 in connection with the Americas restructuring.

Also in June 2014, we cancelled a pipelay system originally intended for the Lay Vessel 108 (“LV 108”), which resulted in a $10.7 million improvement to the cancellation cost estimate included in the $37.8 million of vessel impairment charges recognized during the quarter ended December 31, 2013.

Americas and Corporate Restructuring

We commenced a restructuring of our Americas operations during the quarter ended June 30, 2013, which involves our Morgan City, Louisiana, Houston, Texas, New Orleans, Louisiana and Brazil locations. The restructuring involves, among other things, reductions of management, administrative, fabrication and engineering personnel, and discontinued utilization of the Morgan City facility (after the completion of existing backlog projects, which are currently forecasted to be completed in the third quarter of 2014). Future fabrication operations in the Americas segment are expected to be executed using the Altamira, Mexico facility. In addition, we exited our joint venture operation in Brazil. Costs associated with our Americas restructuring activities primarily include severance and other personnel-related costs, costs associated with exiting the joint venture in Brazil, asset impairment and relocation costs, environmental reserves and future unutilized lease costs.

In October 2013, we announced certain executive management changes that became effective during the fourth quarter of 2013. In March 2014, we changed our organizational structure to orient around offshore and subsea business activities through four primary geographic regions. Costs associated with our corporate reorganization activities will primarily include severance, relocation and other personnel-related costs and costs for advisors.

The following table presents total amounts incurred during six months ended June 30, 2014, as well as amounts incurred from the inception of our restructuring efforts up to June 30, 2014 and amounts expected to be incurred in the future by major type of cost and by segment.

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

NOTE 1—BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

McDermott International, Inc. (“MII”), a corporation incorporated under the laws of the Republic of Panama in 1959, is a leading engineering, procurement, construction and installation (“EPCI”) company focused on designing and executing complex offshore oil and gas projects worldwide. Providing fully integrated EPCI services, we deliver fixed and floating production facilities, pipeline installations and subsea systems from concept to commissioning. Operating in approximately 20 countries across the Americas, Middle East, Asia Pacific, the North Sea and Africa, our integrated resources include approximately 14,000 employees and a diversified fleet of marine vessels, fabrication facilities and engineering offices. We support our activities with comprehensive project management and procurement services, while utilizing our fully integrated capabilities in both shallow water and deepwater construction. Our customers include national, major integrated and other oil and gas companies, and we operate in most major offshore oil and gas producing regions throughout the world. We execute our contracts through a variety of methods, principally fixed-price, but also including cost reimbursable, cost-plus, day-rate and unit-rate basis or some combination of those methods. In these notes to our unaudited condensed consolidated financial statements, unless the context otherwise indicates, “we,” “us” and “our” mean MII and its consolidated subsidiaries.

Basis of Presentation

We have presented our unaudited condensed consolidated financial statements in U.S. Dollars, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim reporting. Financial information and disclosures normally included in our financial statements prepared annually in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted. Readers of these financial statements should, therefore, refer to the consolidated financial statements and the accompanying notes in our annual report on Form 10-K for the year ended December 31, 2013.

We have included all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation. These condensed consolidated financial statements include the accounts of McDermott International, Inc., its consolidated subsidiaries and controlled entities. We use the equity method to account for investments in entities that we do not control, but over which we have significant influence. We generally refer to these entities as “unconsolidated affiliates” or “joint ventures.” We have eliminated all intercompany transactions and accounts.

Certain 2013 amounts in the condensed consolidated balance sheet and statement of cash flows, reflecting the non cash impacts on gain of foreign exchange, have been reclassified to conform to the 2014 presentation.

Business Segments

In March 2014, we changed our organizational structure to orient around our offshore and subsea business activities through four primary geographic regions. The four geographic regions, which we consider to be our operating segments, consist of Asia Pacific, Americas (previously Atlantic), Middle East and North Sea and Africa. The Caspian is no longer considered an operating segment and will continue to be aggregated in the Middle East reporting segment. The North Sea and Africa operating segment is also aggregated into the Middle East reporting segment due to the proximity of regions and similarities in the nature of services provided, economic characteristics and oversight responsibilities. Accordingly, we continue to report financial results under reporting segments consisting of Asia Pacific, Americas and the Middle East. We also report certain corporate and other non-operating activities under the heading “Corporate and other,” which primarily reflects corporate personnel and activities, incentive compensation programs and other costs that are generally fully allocated to our operating segments. The only corporate costs not allocated to our operating segments are the restructuring costs associated with our corporate reorganization. See Note 9 for summarized financial information on our segments.

Revenue Recognition

We determine the appropriate accounting method for each of our long-term contracts before work on the project begins. We generally recognize contract revenues and related costs on a percentage-of-completion method for individual contracts or combinations of contracts based on work performed, man hours, or a cost-to-cost method, as applicable to the activity involved. We include the amount of accumulated contract costs and estimated earnings that exceed billings to customers in contracts in progress. We include billings to customers that exceed accumulated contract costs and estimated earnings in advance billings on contracts. Most long-term contracts contain provisions for progress payments. We expect to invoice customers for and collect all unbilled revenues. Certain costs are generally excluded from the cost-to-cost method of measuring progress, such as significant procurement costs for materials and third-party subcontractors. Total estimated project costs, and resulting income, are affected by changes in the expected cost of materials and labor, productivity, vessel costs, scheduling and other factors. Additionally, external factors such as weather, customer requirements and other factors outside of our control may affect the progress and estimated cost of a project’s completion and, therefore, the timing and amount of revenue and income recognition.

In addition, change orders, which are a normal and recurring part of our business, can increase (sometimes substantially) the future scope and cost of a job. Therefore, change order awards (although frequently beneficial in the long term) can have the short-term effect of reducing the job percentage of completion and thus the revenues and profits recognized to date. We regularly review contract price and cost estimates as the work progresses and reflect adjustments in profit, proportionate to the job percentage of completion in the period when those estimates are revised. Revenue from unapproved change orders is generally recognized to the extent of the lesser of amounts we expect to recover or costs incurred. Additionally, to the extent that claims included in backlog, including those that arise from change orders which are under dispute or which have been previously rejected by the customer, are not resolved in our favor, there could be reductions in or reversals of previously reported revenues and profits, and charges against current earnings, which could be material. Unapproved change orders that are disputed by the customer are treated as claims.

As of June 30, 2014, total unapproved change orders included in our estimates at completion aggregated approximately $297.0 million, of which approximately $44.0 million was included in backlog. As of June 30, 2013, total unapproved change orders included in our estimates at completion aggregated approximately $445.0 million, of which approximately $170.0 million was included in backlog.

Claims Revenue

Claims revenue may relate to various factors, including the procurement of materials, equipment performance failures, change order disputes or schedule disruptions and other delays, including those associated with weather or sea conditions. Claims revenue, when recorded, is only recorded to the extent of the lesser of the amounts we expect to recover or the associated costs incurred in our consolidated financial statements. We include certain unapproved claims in the applicable contract values when we have a legal basis to do so, consider collection to be probable and believe we can reliably estimate the ultimate value. Amounts attributable to unapproved change orders are not included in claims unless and until they are disputed by the customer. We continue to actively engage in negotiations with our customers on our outstanding claims. However, these claims may be resolved at amounts that differ from our current estimates, which could result in increases or decreases in future estimated contract profits or losses. Claims are generally negotiated over the course of the respective projects and many of our projects are long-term in nature. None of the pending claims as of June 30, 2014 were the subject of any litigation proceedings.

The amount of revenues and costs included in our estimates at completion (i.e., contract values) associated with such claims was $6.5 million and $173.4 million as of June 30, 2014 and June 30, 2013, respectively. All of these claim amounts at June 30, 2014 were related to our Middle East segment. Approximately 44%, 10% and 46% of these claim amounts as of June 30, 2013 were related to our Asia Pacific, Americas and Middle East segments, respectively. For the three- and six-month periods ended June 30, 2014, no revenues or costs pertaining to claims were included in our condensed consolidated financial statements. For the three- and six-month periods ended June 30, 2013, $11.0 million and $39.4 million of revenues and costs pertaining to claims were included in our condensed consolidated financial statements, respectively.

Our unconsolidated joint ventures did not include any claims revenue or associated cost in their financial results for the three- and six-month period ended June 30, 2014. For the three- and six-month periods ended June 30, 2013, our unconsolidated joint ventures included nil and $3.7 million, respectively, of claims and associated costs in their financial results.

Deferred Profit Recognition

For contracts as to which we are unable to estimate the final profitability due to their uncommon nature, including first-of-a-kind projects, we recognize equal amounts of revenue and cost until the final results can be estimated more precisely. For these contracts, we only recognize gross margin when reliably estimable and the level of uncertainty has been significantly reduced, which we generally determine to be when the contract is at least 70% complete. We treat long-term construction contracts that contain such a level of risk and uncertainty that estimation of the final outcome is impractical as deferred profit recognition contracts. If, while being accounted for under our deferred profit recognition policy, a current estimate of total contract costs indicates a loss, the projected loss is recognized in full and the project is accounted for under our normal revenue recognition guidelines. At June 30, 2014, no projects were accounted for under our deferred profit recognition policy.

Completed Contract Method

Under the completed contract method, revenue and gross profit is recognized only when a contract is completed or substantially complete. We generally do not enter into fixed-price contracts without an estimate of cost to complete that we believe to be reasonable. However, it is possible that in the time between contract execution and the start of work on a project, we could lose the ability to forecast cost to complete based on intervening events, including, but not limited to, experience on similar projects, civil unrest, strikes and volatility in our expected costs. In such a situation, we would use the completed contract method of accounting for that project. We did not enter into any contracts that we accounted for under the completed contract method during the quarters ended June 30, 2014 and June 30, 2013.

Loss Recognition

A risk associated with fixed-priced contracts is that revenue from customers may not cover increases in our costs. It is possible that current estimates could materially change for various reasons, including, but not limited to, fluctuations in forecasted labor and vessel productivity, vessel repair requirements, weather downtime, subcontractor or supplier performance, pipeline lay rates or steel and other raw material prices. Increases in costs associated with our fixed-price contracts could have a material adverse impact on our consolidated financial condition, results of operations and cash flows. Alternatively, reductions in overall contract costs at completion could materially improve our consolidated financial condition, results of operations and cash flows.

As of June 30, 2014, we have provided for our estimated costs to complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results for any fiscal quarter or year. For all contracts, if a current estimate of total contract cost indicates a loss, the projected loss is recognized in full when determined.

Of the June 30, 2014 backlog, approximately $426.4 million relates to four active projects that are in loss positions, whereby future revenues are expected to equal costs when recognized. Included in this amount is $169.7 million of backlog associated with an EPCI project in Altamira, which is expected to be completed in the fourth quarter of 2015, $133.0 million pertaining to a five-year charter of the Agile in Brazil, which began in early 2012, and $33.1 million relating to a subsea project in the U.S. Gulf of Mexico scheduled for completion during 2014, all of which are being conducted by our Americas segment. The amount also includes $90.6 million of backlog relating to an EPCI project in Saudi Arabia, in our Middle East segment, which is expected to be completed by early 2016. These four projects represent approximately 100% of the backlog amount in a loss position. It is possible that our estimates of gross profit could increase or decrease based on changes in productivity, actual downtime and the resolution of change orders and claims with the customers.

Use of Estimates

We use estimates and assumptions to prepare our financial statements in conformity with GAAP. These estimates and assumptions affect the amounts we report in our financial statements and accompanying notes. Our actual results could differ from these estimates, and variances could materially affect our financial condition and results of operations in future periods. Changes in project estimates generally exclude change orders and changes in scope, but may include, without limitation, unexpected changes in weather conditions, productivity, unanticipated vessel repair requirements, customer, subcontractor and supplier delays and other costs. We generally expect to experience a reasonable amount of unanticipated events, and some of these events can result in significant cost increases above cost amounts we previously estimated. As of June 30, 2014, we have provided for our estimated costs to complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results.

The following is a discussion of our most significant changes in estimates that impacted operating income for the three months and six months ended June 30, 2014 and 2013.

Three months ended June 30, 2014

Operating income for the three months ended June 30, 2014 was impacted by changes in cost estimates relating to projects in each of our segments.

The Asia Pacific segment was positively impacted by net favorable changes in/variances from estimates aggregating approximately $15.8 million, mostly due to reduced cost estimates on a subsea project in Malaysia, which was completed earlier in 2014, of approximately $10.2 million during the three months ended June 30, 2014. Those reduced cost estimates were primarily related to project close-out savings on marine spread and procurement costs. In addition, completion of three smaller projects resulted in project close-out savings of approximately $5.6 million.

The Middle East segment experienced net favorable changes in estimates aggregating approximately $22.0 million, primarily due to increased cost recovery estimates of approximately $29.2 million on a pipelay project in the Caspian, which was completed earlier in 2014. The increased cost recovery estimates were based on positive developments during the three months ended June 30, 2014 from the ongoing project close-out process with the customer. This improvement was partially offset by $7.2 million of increased estimated costs to complete an EPCI project in Saudi Arabia, mainly for the onshore scope on the project.

The Americas segment deteriorated by a net $13.4 million from changes in estimates on three projects. On an EPCI project in Altamira, we increased our estimated costs to complete by approximately $20.0 million, primarily due to projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On a subsea project in the US Gulf of Mexico, we increased our estimated costs to complete by approximately $23.3 million, primarily due to equipment downtime issues on the North Ocean 102 (the “NO 102”), our primary vessel working on the project. This project is in a loss position and is estimated to be completed in the third quarter of 2014. These negative impacts were partly offset by approximately $30.0 million of project close-out improvements on an EPCI project in Brazil, which was completed earlier in 2014, from marine cost reductions and increased recoveries due to successful developments from ongoing approval process for additional weather-related compensation.

Six months ended June 30, 2014

Operating income for the six months ended June 30, 2014 was impacted by changes in cost estimates relating to projects in each of our segments.

The Asia Pacific segment experienced net favorable changes in estimates aggregating approximately $30.8 million, mostly due to changes in estimates on a subsea project in Malaysia during the six months ended June 30, 2014. Those changes were primarily related to productivity improvements on our marine vessels and offshore support activities, as well as project close-out savings.

The Middle East segment was negatively impacted by net unfavorable changes aggregating approximately $12.7 million, due to changes in five projects in the region. On three EPCI projects in Saudi Arabia, we increased our estimated cost at completion by approximately $35.3 million, primarily as a result of vessel downtime due to weather and standby delays (which may be recoverable from the customer, but which were not recognizable at June 30, 2014), reduced productivity levels and increased cost estimates to complete the onshore scope of one of the projects. On an EPCI project in Saudi Arabia, we increased our overall estimated costs to complete by approximately $6.6 million of cost overruns related to (1) the onshore work which was substantially completed in July 2014, and (2) delays in completing the offshore work, due to limited access to the project site, which is caused by schedule conflicts with another contractor. These negative changes were partly offset by approximately $29.1 million of increased cost recovery estimates on a pipelay project in the Caspian, based on positive developments during the three months ended June 30, 2014 from the ongoing project close-out process with the customer.

The Americas segment was negatively impacted by net unfavorable changes in estimates aggregating approximately $39.3 million associated with four projects. On an EPCI project in Altamira, we increased our estimated costs to complete by approximately $55.4 million, due to liquidated damages and extended project management costs arising from expected project delays, projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On a subsea project in the US Gulf of Mexico, we increased our estimated costs to complete by approximately $22.5 million, primarily due to equipment downtime issues on the NO 102, our primary vessel working on the project. This project is in a loss position and is estimated to be completed in the third quarter of 2014. These negative impacts were partly offset by $33.7 million of project close out improvements on an EPCI project in Brazil from marine cost reductions upon completion of activities and increased recoveries due to successful developments from ongoing approval process for additional weather related compensation. We also recognized $4.9 million cost reductions, mainly due to project close-out improvements, on a marine installation project in the US Gulf of Mexico.

Three months ended June 30, 2013

The Asia Pacific segment was primarily impacted by changes in estimates on one subsea project in Malaysia. On that project, we increased our estimated cost at completion by approximately $62.0 million in the three months ended June 30, 2013, primarily due to delays resulting from direct and indirect impacts of equipment modification problems during the final commissioning stage of a major pipe-lay systems upgrade to the North Ocean 105 (the “NO 105”), which was required to execute the project scope. As a result of these delays the as-bid project execution plan was no longer achievable. As a result, the revised project execution plan required a split marine campaign in order to avoid working in adverse weather periods. Mechanical downtime of a third-party support vessel also contributed to project delays. In consideration of these factors, the expected completion date for the project was extended from the fourth quarter 2013 to the middle of 2014. In addition, the extended schedule resulted in forecasted liquidated damages under the contract terms with the customer. This project was completed during the three months ended June 30, 2014.

The Middle East segment was impacted by changes in estimates on one of our EPCI projects in Saudi Arabia. On that project, we increased our estimated cost at completion by approximately $38.0 million in the three months ended June 30, 2013, primarily as a result of revisions to the project’s execution plan, increases in our estimated cost to complete due to an extended offshore hookup campaign requiring multiple vessel mobilizations and, to a lesser extent, delays in the completion of onshore activities. While the project recognized losses in the three months ended June 30, 2013, it remains in an overall profitable position.

The Americas segment was impacted by changes in estimates on two projects. On one of those projects, we recognized approximately $7.0 million of incremental project losses in the three months ended June 30, 2013, primarily due to lower than expected labor productivity on a fabrication project in Morgan City. This project was completed during the year ended December 31, 2013. We also recognized project losses of approximately $3.0 million in the three months ended June 30, 2013 on another fabrication project in Morgan City, which was completed during the quarter ended June 30, 2013.

Six months ended June 30, 2013

The Asia Pacific segment was primarily impacted by changes in estimates on three projects. On one project (the project in Malaysia described above), we increased our estimated cost at completion by approximately $66.0 million in the six months ended June 30, 2013, primarily due to delays resulting from direct and indirect impacts of the equipment modification problems during the final commissioning stage of the major pipe-lay systems upgrade to the NO 105 and the other factors described above. We also benefited from reduced estimated costs during contract close-out of approximately $14 million during the three-month period ended March 31, 2013, primarily due to efficiencies associated with marine campaigns on two our EPCI projects, both of which were completed in the six-month period ended June 30, 2013.

The Middle East segment was impacted by changes in estimates on the EPCI project in Saudi Arabia discussed above. On that project, we increased our estimated cost at completion by approximately $43.0 million in the six months ended June 30, 2013, primarily as a result of revisions to the project’s execution plan, increases in our estimated cost to complete due to an extended offshore hookup campaign requiring multiple vessel mobilizations and, to a lesser extent, delays in the completion of onshore activities. While the project recognized losses in the three months ended June 30, 2013, it remains in an overall profitable position.

The Americas segment was impacted by changes in estimates on one fabrication project in Morgan City. On that project, we recognized approximately $14.0 million of incremental project losses in the six months ended June 30, 2013, primarily due to lower than expected labor productivity. This project was completed during the year ended December 31, 2013.

Loss Contingencies

We record liabilities for loss contingencies when it is probable that a liability has been incurred and the amount of loss is reasonably estimable. We provide disclosure when there is a reasonable possibility that the ultimate loss will exceed the recorded provision or if such loss is not reasonably estimable. We are currently involved in litigation and other proceedings, as discussed in Note 10. We have accrued our estimates of the probable losses associated with these matters, and associated legal costs are generally recognized in selling, general and administrative expenses as incurred. However, our losses are typically resolved over long periods of time and are often difficult to estimate due to various factors, including the possibility of multiple actions by third parties. Therefore, it is possible future earnings could be affected by changes in our estimates related to these matters.

Cash and Cash Equivalents

Our cash and cash equivalents are highly liquid investments with maturities of three months or less when we purchase them. We record cash and cash equivalents as restricted when we are unable to freely use such cash and cash equivalents for our general operating purposes. A majority of our restricted cash and cash equivalents represents collateralizing letters of credit as further discussed in Note 3.

Investments

We classify investments available for current operations as current assets in the accompanying balance sheets, and we classify investments held for long-term purposes as noncurrent assets. We adjust the amortized cost of debt securities for amortization of premiums and accretion of discounts to maturity. That amortization is included in interest income. We include realized gains and losses on our investments in other income (expense)—net. The cost of securities sold is based on the specific identification method. We include interest earned on securities in interest income.

Investments in Unconsolidated Affiliates

We generally use the equity method of accounting for affiliates in which our investment ownership ranges from 20% to 50%, and in which we do not exercise control over the entity. Currently, most of our investments in affiliates that are not consolidated are recorded using the equity method.

Accounts Receivable

Accounts Receivable—Trade, Net

A summary of contract receivables is as follows:

	June 30, 2014			December 31, 2013
	(In thousands)
Contract receivables:
Contracts in progress	$	121,920		$	192,745
Completed contracts		42,743			77,248
Retainages		85,587			127,698
Unbilled		4,303			14,571
Less allowances		(29,094	)		(30,404	)
Accounts receivable—trade, net	$	225,459		$	381,858

We expect to invoice our unbilled receivables once certain milestones or other metrics are reached, and we expect to collect all unbilled amounts. We believe that our provision for losses on uncollectible accounts receivable is adequate for our credit loss exposure.

Contract retainages generally represent amounts withheld by our customers until project completion, in accordance with the terms of the applicable contracts. The following is a summary of retainages on our contracts:

	June 30, 2014		December 31, 2013
	(In thousands)
Retainages expected to be collected within one year	$	85,587	$	127,698
Retainages expected to be collected after one year		145,883		65,365
Total retainages	$	231,470	$	193,063

We have included in accounts receivable—trade, net, retainages expected to be collected within one year.

Accounts Receivable—Other

A summary of accounts receivable— other is as follows:

	June 30, 2014		December 31, 2013
	(In thousands)
Receivables from unconsolidated affiliates	$	18,207	$	36,181
Other taxes receivable		23,678		14,934
Accrued unbilled revenue		13,219		15,696
Asset derivatives		5,055		11,641
Employee receivables		3,973		4,532
Other		8,215		6,289
Accounts receivables – other	$	72,347	$	89,273

Employee receivables are expected to be collected within 12 months, and any allowance for doubtful accounts on our accounts receivable—other is based on our estimate of the amount of probable losses due to the inability to collect these amounts (based on historical collection experience and other available information). As of June 30, 2014 and December 31, 2013, no such allowance for doubtful accounts was recorded.

Contracts in Progress and Advance Billings on Contracts

Contracts in progress were $440.3 million and $426.0 million at June 30, 2014 and December 31, 2013, respectively. Advance billings on contracts were $204.5 million at June 30, 2014 and $278.9 million at December 31, 2013. A detail of the components of contracts in progress and advance billings on contracts is as follows:

	June 30, 2014		December 31, 2013
	(In thousands)
Costs incurred less costs of revenue recognized	$	94,167	$	65,113

Other Non-Current Assets

We have included debt issuance costs in other assets. We amortize debt issuance costs as interest expense on a straight-line basis over the life of the related debt. The following summarizes the changes in the carrying amount of these assets:

	Six months ended June 30, 2014			Year ended December 31, 2013
	(In thousands)
Balance at beginning of period	$	14,951		$	13,761
Debt issuance costs		45,521			4,905
Former Credit Agreement debt issuance cost write off		(11,913	)		—
Amortization of interest expense		(4,315	)		(3,715	)
Balance at end of period	$	44,244		$	14,951

Also included in other non-current assets is long-term deferred drydock expenses, long-term prepaid rent and other prepaid expenses.

Fair Value of Financial Instruments

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 an orderly transaction between market participants at the measurement date. An established hierarchy for inputs is used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors that market participants would use in valuing the asset or liability.

Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

• Level 1—inputs are based upon quoted prices for identical instruments traded in active markets.

• Level 2—inputs are based upon quoted prices for similar instruments in active markets, quoted prices for similar or identical instruments in inactive markets and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets and liabilities.

• Level 3—inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar valuation techniques.

The carrying amounts that we have reported for financial instruments, including cash and cash equivalents, accounts receivables and accounts payable approximate their fair values. See Note 6 for additional information regarding fair value measurements.

Derivative Financial Instruments

Our worldwide operations give rise to exposure to changes in certain market conditions, which may adversely impact our financial performance. When we deem it appropriate, we use derivatives as a risk management tool to mitigate the potential impacts of certain market risks. The primary market risk we manage through the use of derivative instruments is movement in foreign currency exchange rates. We use foreign currency derivative contracts to reduce the impact of changes in foreign currency exchange rates on our operating results. We use these instruments to hedge our exposure associated with revenues and/or costs on our long-term contracts and other cash flow exposures that are denominated in currencies other than our operating entities’ functional currencies. We do not hold or issue financial instruments for trading or other speculative purposes.

In certain cases, contracts with our customers contain provisions under which some payments from our customers are denominated in U.S. Dollars and other payments are denominated in a foreign currency. In general, the payments denominated in a foreign currency are designed to compensate us for costs that we expect to incur in such foreign currency. In these cases, we may use derivative instruments to reduce the risks associated with foreign currency exchange rate fluctuations arising from differences in timing of our foreign currency cash inflows and outflows. See Note 5 for additional information regarding derivative financial instruments.

Foreign Currency Translation

We translate assets and liabilities of our foreign operations, other than operations in highly inflationary economies, into U.S. Dollars at period-end exchange rates, and we translate income statement items at average exchange rates for the periods presented. We record adjustments resulting from the translation of foreign currency financial statements as a component of accumulated other comprehensive income (loss) (“AOCI”), net of tax.

Earnings per Share

We have computed earnings per common share on the basis of the weighted average number of common shares, and, where dilutive, common share equivalents, outstanding during the indicated periods. See Note 8 for our earnings per share computations.

Accumulated Other Comprehensive Loss

The components of AOCI included in stockholders’ equity are as follows:

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. This ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. It also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 is effective for us for annual and interim reporting periods beginning after December 15, 2016, with early application not permitted. We have the choice to apply it either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying it at the date of initial application (January 1, 2017) and not adjusting comparative information. We are currently evaluating the requirements of this ASU and have not yet determined its impact on our consolidated financial statements.

In July 2013, FASB issued an update to the topic Income Taxes. The update clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if settlement is required or expected in the event the uncertain tax position is disallowed. In situations where these items are not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the applicable jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The update is effective for 2014, and the adoption of this update did not have a material impact on our condensed consolidated financial statements.

NOTE 10—COMMITMENTS AND CONTINGENCIES

Investigations and Litigation

On or about August 23, 2004, a declaratory judgment action entitled Certain Underwriters at Lloyd’s London, et al. v. J. Ray McDermott, Inc. et al., was filed by certain underwriters at Lloyd’s, London and Threadneedle Insurance Company Limited (the “London Insurers”), in the 23rd Judicial District Court, Assumption Parish, Louisiana, against MII, J. Ray McDermott, Inc. (“JRMI”) and two insurer defendants, Travelers and INA, seeking a declaration that the London Insurers have no obligation to indemnify MII and JRMI for certain bodily injury claims, including claims for asbestos and welding rod fume personal injury which have been filed by claimants in various state courts. Additionally, Travelers filed a cross-claim requesting a declaration of non-coverage in approximately 20 underlying matters. This proceeding was stayed by the Court on January 3, 2005. We do not believe an adverse judgment or material losses in this matter are probable, and, accordingly, we have not accrued any amounts relating to this contingency. Although there is a possibility of an adverse judgment, the amount or potential range of loss is not estimable at this time. The insurer-plaintiffs in this matter commenced this proceeding in a purported attempt to obtain a determination of insurance coverage obligations for occupational exposure and/or environmental matters for which we have given notice that we could potentially seek coverage. Because estimating losses would require, for every matter, known and unknown, on a case by case basis, anticipating what impact on coverage a judgment would have and a determination of an otherwise expected insured value, damages cannot be reasonably estimated.

On December 16, 2005, a proceeding entitled Antoine, et al. vs. J. Ray McDermott, Inc., et al. (“Antoine Suit”), was filed in the 24th Judicial District Court, Jefferson Parish, Louisiana, by approximately 88 plaintiffs against approximately 215 defendants, including our subsidiaries formerly known as JRMI and Delta Hudson Engineering Corporation (“DHEC”), generally alleging injuries for exposure to asbestos, and unspecified chemicals, metals and noise while the plaintiffs were allegedly employed as Jones Act seamen. This case was dismissed by the Court on January 10, 2007, without prejudice to plaintiffs’ rights to refile their claims. On January 29, 2007, 21 plaintiffs from the dismissed Antoine Suit filed a matter entitled Boudreaux, et al. v. McDermott, Inc., et al. (the “Boudreaux Suit”), in the United States District Court for the Southern District of Texas, against JRMI and our subsidiary formerly known as McDermott Incorporated, and approximately 30 other employer defendants, alleging Jones Act seaman status and generally alleging exposure to welding fumes, solvents, dyes, industrial paints and noise. The Boudreaux Suit was transferred to the United States District Court for the Eastern District of Louisiana on May 2, 2007, which entered an order in September 2007 staying the matter until further order of the Court due to the bankruptcy filing of one of the co-defendants. On June 18, 2014, the Boudreaux Suit was voluntarily dismissed without prejudice. Additionally, on January 29, 2007, another 43 plaintiffs from the dismissed Antoine Suit filed a matter entitled Antoine, et al. v. McDermott, Inc., et al. (the “New Antoine Suit”), in the 164th Judicial District Court for Harris County, Texas, against JRMI, our subsidiary formerly known as McDermott Incorporated and approximately 65 other employer defendants and 42 maritime products defendants, alleging Jones Act seaman status and generally alleging personal injuries for exposure to asbestos and noise. On April 27, 2007, the District Court entered an order staying all activity and deadlines in the New Antoine Suit, other than service of process and answer/appearance dates, until further order of the Court. The New Antoine Suit plaintiffs filed a motion to lift the stay on February 20, 2009, which is pending before the Texas District Court. On April 4, 2014, 20 of the plaintiffs in the New Antoine Suit voluntarily dismissed their claims against McDermott without prejudice to re-filing. The remaining plaintiffs seek monetary damages in an unspecified amount and attorneys’ fees. We cannot reasonably estimate the extent of a potential judgment against us, if any, and we intend to vigorously defend this suit.

On August 15, 2013 and August 20, 2013, two separate alleged purchasers of our common stock filed purported class action complaints against us, Stephen M. Johnson and Perry L. Elders in the United States District Court for the Southern District of Texas. Both of the complaints sought to represent a class of purchasers of our stock between November 6, 2012 and August 5, 2013, and alleged, among other things, that the defendants violated federal securities laws by disseminating materially false and misleading information and failing to disclose material information relating to weaknesses in project bidding and execution, poor risk evaluation, poor project management and losses in each of our reporting segments. Each complaint sought relief, including unspecified compensatory damages and an award for attorneys’ fees and other costs. By order dated December 5, 2013, the District Court consolidated the two cases and appointed a lead plaintiff and lead plaintiff’s counsel. The lead plaintiff filed a consolidated amended complaint on February 6, 2014. The consolidated amended complaint asserts substantially the same claims as were made in the two original complaints, with some additional factual allegations, and purports to extend the class period to August 6, 2013. It also seeks relief, including unspecified compensatory damages and an award for attorneys’ fees and other costs. On April 7, 2014, MII and the other defendants filed a motion to dismiss the case. On May 22, 2014, the lead plaintiff filed an opposition to the motion to dismiss, and MII and the other defendants filed a reply in support of the defendants’ motion to dismiss on June 23, 2014. The motion to dismiss is still pending before the District Court. We believe the substantive allegations contained in the consolidated amended complaint are without merit, and we intend to defend against these claims vigorously.

Additionally, due to the nature of our business, we and our affiliates are, from time to time, involved in litigation or subject to disputes or claims related to our business activities, including, among other things:

• performance—or warranty-related matters under our customer and supplier contracts and other business arrangements; and

• workers’ compensation claims, Jones Act claims, occupational hazard claims, including asbestos-exposure claims, premises liability claims and other claims.

Based upon our prior experience, we do not expect that any of these other litigation proceedings, disputes and claims will have a material adverse effect on our consolidated financial condition, results of operations or cash flows; however, because of the inherent uncertainty of litigation and, in some cases, the availability and amount of potentially applicable insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs.

Environmental Matters

We have been identified as a potentially responsible party at various cleanup sites under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”). CERCLA and other environmental laws can impose liability for the entire cost of cleanup on any of the potentially responsible parties, regardless of fault or the lawfulness of the original conduct. Generally, however, where there are multiple responsible parties, a final allocation of costs is made based on the amount and type of wastes disposed of by each party and the number of financially viable parties, although this may not be the case with respect to any particular site. We have not been determined to be a major contributor of wastes to any of these sites. On the basis of our relative contribution of waste to each site, we expect our share of the ultimate liability for the various sites will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows in any given year.

At June 30, 2014, we had total environmental reserves of $6.0 million, all of which was included in noncurrent liabilities. We established an environmental reserve of $5.6 million in connection with our plan to discontinue the utilization of our Morgan City fabrication facility. Inherent in the estimates of those reserves and recoveries are our expectations regarding the levels of contamination, remediation costs and recoverability from other parties, which may vary significantly as remediation activities progress. Accordingly, changes in estimates could result in material adjustments to our operating results, and the ultimate loss may differ materially from the amounts we have provided for in our consolidated financial statements.

Contracts Containing Liquidated Damages Provisions

Some of our contracts contain provisions that require us to pay liquidated damages if we are responsible for the failure to meet specified contractual milestone dates and the applicable customer asserts a claim under these provisions. These contracts define the conditions under which our customers may make claims against us for liquidated damages. In many cases in which we have historically had potential exposure for liquidated damages, such damages ultimately were not asserted by our customers. As of June 30, 2014, it is possible that we may incur liabilities for liquidated damages aggregating approximately $133.8 million, of which approximately $37.5 million has been recorded in our financial statements, based on our actual or projected failure to meet certain specified contractual milestone dates. The dates for which these potential liquidated damages could arise extend to June 2015. We believe we will be successful in obtaining schedule extensions or other customer-agreed changes that should resolve the potential for unaccrued liquidated damages. Accordingly, we believe that no amounts for these unaccrued liquidated damages in excess of the amounts currently reflected in our financial statements are probable of being paid by us. However, we may not achieve relief on some or all of the issues involved and, as a result, could be subject to higher damage amounts.

Contractual Obligations

As of June 30, 2014, we had outstanding obligations related to our new vessel construction contracts on the LV 108 and DLV 2000 of $482.2 million in the aggregate, with $237.2 million and $245.0 million due in the years ending December 31, 2014 and 2015, respectively.

Accounting Policies [Abstract]

Nature of Operations

Nature of Operations

McDermott International, Inc. (“MII”), a corporation incorporated under the laws of the Republic of Panama in 1959, is a leading engineering, procurement, construction and installation (“EPCI”) company focused on designing and executing complex offshore oil and gas projects worldwide. Providing fully integrated EPCI services, we deliver fixed and floating production facilities, pipeline installations and subsea systems from concept to commissioning. Operating in approximately 20 countries across the Americas, Middle East, Asia Pacific, the North Sea and Africa, our integrated resources include approximately 14,000 employees and a diversified fleet of marine vessels, fabrication facilities and engineering offices. We support our activities with comprehensive project management and procurement services, while utilizing our fully integrated capabilities in both shallow water and deepwater construction. Our customers include national, major integrated and other oil and gas companies, and we operate in most major offshore oil and gas producing regions throughout the world. We execute our contracts through a variety of methods, principally fixed-price, but also including cost reimbursable, cost-plus, day-rate and unit-rate basis or some combination of those methods. In these notes to our unaudited condensed consolidated financial statements, unless the context otherwise indicates, “we,” “us” and “our” mean MII and its consolidated subsidiaries.

Basis of Presentation

Basis of Presentation

We have presented our unaudited condensed consolidated financial statements in U.S. Dollars, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim reporting. Financial information and disclosures normally included in our financial statements prepared annually in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted. Readers of these financial statements should, therefore, refer to the consolidated financial statements and the accompanying notes in our annual report on Form 10-K for the year ended December 31, 2013.

We have included all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation. These condensed consolidated financial statements include the accounts of McDermott International, Inc., its consolidated subsidiaries and controlled entities. We use the equity method to account for investments in entities that we do not control, but over which we have significant influence. We generally refer to these entities as “unconsolidated affiliates” or “joint ventures.” We have eliminated all intercompany transactions and accounts.

Certain 2013 amounts in the condensed consolidated balance sheet and statement of cash flows, reflecting the non cash impacts on gain of foreign exchange, have been reclassified to conform to the 2014 presentation.

Business Segments

Business Segments

In March 2014, we changed our organizational structure to orient around our offshore and subsea business activities through four primary geographic regions. The four geographic regions, which we consider to be our operating segments, consist of Asia Pacific, Americas (previously Atlantic), Middle East and North Sea and Africa. The Caspian is no longer considered an operating segment and will continue to be aggregated in the Middle East reporting segment. The North Sea and Africa operating segment is also aggregated into the Middle East reporting segment due to the proximity of regions and similarities in the nature of services provided, economic characteristics and oversight responsibilities. Accordingly, we continue to report financial results under reporting segments consisting of Asia Pacific, Americas and the Middle East. We also report certain corporate and other non-operating activities under the heading “Corporate and other,” which primarily reflects corporate personnel and activities, incentive compensation programs and other costs that are generally fully allocated to our operating segments. The only corporate costs not allocated to our operating segments are the restructuring costs associated with our corporate reorganization. See Note 9 for summarized financial information on our segments.

Revenue Recognition

Revenue Recognition

We determine the appropriate accounting method for each of our long-term contracts before work on the project begins. We generally recognize contract revenues and related costs on a percentage-of-completion method for individual contracts or combinations of contracts based on work performed, man hours, or a cost-to-cost method, as applicable to the activity involved. We include the amount of accumulated contract costs and estimated earnings that exceed billings to customers in contracts in progress. We include billings to customers that exceed accumulated contract costs and estimated earnings in advance billings on contracts. Most long-term contracts contain provisions for progress payments. We expect to invoice customers for and collect all unbilled revenues. Certain costs are generally excluded from the cost-to-cost method of measuring progress, such as significant procurement costs for materials and third-party subcontractors. Total estimated project costs, and resulting income, are affected by changes in the expected cost of materials and labor, productivity, vessel costs, scheduling and other factors. Additionally, external factors such as weather, customer requirements and other factors outside of our control may affect the progress and estimated cost of a project’s completion and, therefore, the timing and amount of revenue and income recognition.

In addition, change orders, which are a normal and recurring part of our business, can increase (sometimes substantially) the future scope and cost of a job. Therefore, change order awards (although frequently beneficial in the long term) can have the short-term effect of reducing the job percentage of completion and thus the revenues and profits recognized to date. We regularly review contract price and cost estimates as the work progresses and reflect adjustments in profit, proportionate to the job percentage of completion in the period when those estimates are revised. Revenue from unapproved change orders is generally recognized to the extent of the lesser of amounts we expect to recover or costs incurred. Additionally, to the extent that claims included in backlog, including those that arise from change orders which are under dispute or which have been previously rejected by the customer, are not resolved in our favor, there could be reductions in or reversals of previously reported revenues and profits, and charges against current earnings, which could be material. Unapproved change orders that are disputed by the customer are treated as claims.

As of June 30, 2014, total unapproved change orders included in our estimates at completion aggregated approximately $297.0 million, of which approximately $44.0 million was included in backlog. As of June 30, 2013, total unapproved change orders included in our estimates at completion aggregated approximately $445.0 million, of which approximately $170.0 million was included in backlog.

Claims Revenue

Claims revenue may relate to various factors, including the procurement of materials, equipment performance failures, change order disputes or schedule disruptions and other delays, including those associated with weather or sea conditions. Claims revenue, when recorded, is only recorded to the extent of the lesser of the amounts we expect to recover or the associated costs incurred in our consolidated financial statements. We include certain unapproved claims in the applicable contract values when we have a legal basis to do so, consider collection to be probable and believe we can reliably estimate the ultimate value. Amounts attributable to unapproved change orders are not included in claims unless and until they are disputed by the customer. We continue to actively engage in negotiations with our customers on our outstanding claims. However, these claims may be resolved at amounts that differ from our current estimates, which could result in increases or decreases in future estimated contract profits or losses. Claims are generally negotiated over the course of the respective projects and many of our projects are long-term in nature. None of the pending claims as of June 30, 2014 were the subject of any litigation proceedings.

The amount of revenues and costs included in our estimates at completion (i.e., contract values) associated with such claims was $6.5 million and $173.4 million as of June 30, 2014 and June 30, 2013, respectively. All of these claim amounts at June 30, 2014 were related to our Middle East segment. Approximately 44%, 10% and 46% of these claim amounts as of June 30, 2013 were related to our Asia Pacific, Americas and Middle East segments, respectively. For the three- and six-month periods ended June 30, 2014, no revenues or costs pertaining to claims were included in our condensed consolidated financial statements. For the three- and six-month periods ended June 30, 2013, $11.0 million and $39.4 million of revenues and costs pertaining to claims were included in our condensed consolidated financial statements, respectively.

Our unconsolidated joint ventures did not include any claims revenue or associated cost in their financial results for the three- and six-month period ended June 30, 2014. For the three- and six-month periods ended June 30, 2013, our unconsolidated joint ventures included nil and $3.7 million, respectively, of claims and associated costs in their financial results.

Deferred Profit Recognition

For contracts as to which we are unable to estimate the final profitability due to their uncommon nature, including first-of-a-kind projects, we recognize equal amounts of revenue and cost until the final results can be estimated more precisely. For these contracts, we only recognize gross margin when reliably estimable and the level of uncertainty has been significantly reduced, which we generally determine to be when the contract is at least 70% complete. We treat long-term construction contracts that contain such a level of risk and uncertainty that estimation of the final outcome is impractical as deferred profit recognition contracts. If, while being accounted for under our deferred profit recognition policy, a current estimate of total contract costs indicates a loss, the projected loss is recognized in full and the project is accounted for under our normal revenue recognition guidelines. At June 30, 2014, no projects were accounted for under our deferred profit recognition policy.

Completed Contract Method

Under the completed contract method, revenue and gross profit is recognized only when a contract is completed or substantially complete. We generally do not enter into fixed-price contracts without an estimate of cost to complete that we believe to be reasonable. However, it is possible that in the time between contract execution and the start of work on a project, we could lose the ability to forecast cost to complete based on intervening events, including, but not limited to, experience on similar projects, civil unrest, strikes and volatility in our expected costs. In such a situation, we would use the completed contract method of accounting for that project. We did not enter into any contracts that we accounted for under the completed contract method during the quarters ended June 30, 2014 and June 30, 2013.

Loss Recognition

A risk associated with fixed-priced contracts is that revenue from customers may not cover increases in our costs. It is possible that current estimates could materially change for various reasons, including, but not limited to, fluctuations in forecasted labor and vessel productivity, vessel repair requirements, weather downtime, subcontractor or supplier performance, pipeline lay rates or steel and other raw material prices. Increases in costs associated with our fixed-price contracts could have a material adverse impact on our consolidated financial condition, results of operations and cash flows. Alternatively, reductions in overall contract costs at completion could materially improve our consolidated financial condition, results of operations and cash flows.

As of June 30, 2014, we have provided for our estimated costs to complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results for any fiscal quarter or year. For all contracts, if a current estimate of total contract cost indicates a loss, the projected loss is recognized in full when determined.

Of the June 30, 2014 backlog, approximately $426.4 million relates to four active projects that are in loss positions, whereby future revenues are expected to equal costs when recognized. Included in this amount is $169.7 million of backlog associated with an EPCI project in Altamira, which is expected to be completed in the fourth quarter of 2015, $133.0 million pertaining to a five-year charter of the Agile in Brazil, which began in early 2012, and $33.1 million relating to a subsea project in the U.S. Gulf of Mexico scheduled for completion during 2014, all of which are being conducted by our Americas segment. The amount also includes $90.6 million of backlog relating to an EPCI project in Saudi Arabia, in our Middle East segment, which is expected to be completed by early 2016. These four projects represent approximately 100% of the backlog amount in a loss position. It is possible that our estimates of gross profit could increase or decrease based on changes in productivity, actual downtime and the resolution of change orders and claims with the customers.

Use of Estimates

Use of Estimates

We use estimates and assumptions to prepare our financial statements in conformity with GAAP. These estimates and assumptions affect the amounts we report in our financial statements and accompanying notes. Our actual results could differ from these estimates, and variances could materially affect our financial condition and results of operations in future periods. Changes in project estimates generally exclude change orders and changes in scope, but may include, without limitation, unexpected changes in weather conditions, productivity, unanticipated vessel repair requirements, customer, subcontractor and supplier delays and other costs. We generally expect to experience a reasonable amount of unanticipated events, and some of these events can result in significant cost increases above cost amounts we previously estimated. As of June 30, 2014, we have provided for our estimated costs to complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results.

The following is a discussion of our most significant changes in estimates that impacted operating income for the three months and six months ended June 30, 2014 and 2013.

Three months ended June 30, 2014

Operating income for the three months ended June 30, 2014 was impacted by changes in cost estimates relating to projects in each of our segments.

The Asia Pacific segment was positively impacted by net favorable changes in/variances from estimates aggregating approximately $15.8 million, mostly due to reduced cost estimates on a subsea project in Malaysia, which was completed earlier in 2014, of approximately $10.2 million during the three months ended June 30, 2014. Those reduced cost estimates were primarily related to project close-out savings on marine spread and procurement costs. In addition, completion of three smaller projects resulted in project close-out savings of approximately $5.6 million.

The Middle East segment experienced net favorable changes in estimates aggregating approximately $22.0 million, primarily due to increased cost recovery estimates of approximately $29.2 million on a pipelay project in the Caspian, which was completed earlier in 2014. The increased cost recovery estimates were based on positive developments during the three months ended June 30, 2014 from the ongoing project close-out process with the customer. This improvement was partially offset by $7.2 million of increased estimated costs to complete an EPCI project in Saudi Arabia, mainly for the onshore scope on the project.

The Americas segment deteriorated by a net $13.4 million from changes in estimates on three projects. On an EPCI project in Altamira, we increased our estimated costs to complete by approximately $20.0 million, primarily due to projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On a subsea project in the US Gulf of Mexico, we increased our estimated costs to complete by approximately $23.3 million, primarily due to equipment downtime issues on the North Ocean 102 (the “NO 102”), our primary vessel working on the project. This project is in a loss position and is estimated to be completed in the third quarter of 2014. These negative impacts were partly offset by approximately $30.0 million of project close-out improvements on an EPCI project in Brazil, which was completed earlier in 2014, from marine cost reductions and increased recoveries due to successful developments from ongoing approval process for additional weather-related compensation.

Six months ended June 30, 2014

Operating income for the six months ended June 30, 2014 was impacted by changes in cost estimates relating to projects in each of our segments.

The Asia Pacific segment experienced net favorable changes in estimates aggregating approximately $30.8 million, mostly due to changes in estimates on a subsea project in Malaysia during the six months ended June 30, 2014. Those changes were primarily related to productivity improvements on our marine vessels and offshore support activities, as well as project close-out savings.

The Middle East segment was negatively impacted by net unfavorable changes aggregating approximately $12.7 million, due to changes in five projects in the region. On three EPCI projects in Saudi Arabia, we increased our estimated cost at completion by approximately $35.3 million, primarily as a result of vessel downtime due to weather and standby delays (which may be recoverable from the customer, but which were not recognizable at June 30, 2014), reduced productivity levels and increased cost estimates to complete the onshore scope of one of the projects. On an EPCI project in Saudi Arabia, we increased our overall estimated costs to complete by approximately $6.6 million of cost overruns related to (1) the onshore work which was substantially completed in July 2014, and (2) delays in completing the offshore work, due to limited access to the project site, which is caused by schedule conflicts with another contractor. These negative changes were partly offset by approximately $29.1 million of increased cost recovery estimates on a pipelay project in the Caspian, based on positive developments during the three months ended June 30, 2014 from the ongoing project close-out process with the customer.

The Americas segment was negatively impacted by net unfavorable changes in estimates aggregating approximately $39.3 million associated with four projects. On an EPCI project in Altamira, we increased our estimated costs to complete by approximately $55.4 million, due to liquidated damages and extended project management costs arising from expected project delays, projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On a subsea project in the US Gulf of Mexico, we increased our estimated costs to complete by approximately $22.5 million, primarily due to equipment downtime issues on the NO 102, our primary vessel working on the project. This project is in a loss position and is estimated to be completed in the third quarter of 2014. These negative impacts were partly offset by $33.7 million of project close out improvements on an EPCI project in Brazil from marine cost reductions upon completion of activities and increased recoveries due to successful developments from ongoing approval process for additional weather related compensation. We also recognized $4.9 million cost reductions, mainly due to project close-out improvements, on a marine installation project in the US Gulf of Mexico.

Three months ended June 30, 2013

The Asia Pacific segment was primarily impacted by changes in estimates on one subsea project in Malaysia. On that project, we increased our estimated cost at completion by approximately $62.0 million in the three months ended June 30, 2013, primarily due to delays resulting from direct and indirect impacts of equipment modification problems during the final commissioning stage of a major pipe-lay systems upgrade to the North Ocean 105 (the “NO 105”), which was required to execute the project scope. As a result of these delays the as-bid project execution plan was no longer achievable. As a result, the revised project execution plan required a split marine campaign in order to avoid working in adverse weather periods. Mechanical downtime of a third-party support vessel also contributed to project delays. In consideration of these factors, the expected completion date for the project was extended from the fourth quarter 2013 to the middle of 2014. In addition, the extended schedule resulted in forecasted liquidated damages under the contract terms with the customer. This project was completed during the three months ended June 30, 2014.

The Middle East segment was impacted by changes in estimates on one of our EPCI projects in Saudi Arabia. On that project, we increased our estimated cost at completion by approximately $38.0 million in the three months ended June 30, 2013, primarily as a result of revisions to the project’s execution plan, increases in our estimated cost to complete due to an extended offshore hookup campaign requiring multiple vessel mobilizations and, to a lesser extent, delays in the completion of onshore activities. While the project recognized losses in the three months ended June 30, 2013, it remains in an overall profitable position.

The Americas segment was impacted by changes in estimates on two projects. On one of those projects, we recognized approximately $7.0 million of incremental project losses in the three months ended June 30, 2013, primarily due to lower than expected labor productivity on a fabrication project in Morgan City. This project was completed during the year ended December 31, 2013. We also recognized project losses of approximately $3.0 million in the three months ended June 30, 2013 on another fabrication project in Morgan City, which was completed during the quarter ended June 30, 2013.

Six months ended June 30, 2013

The Asia Pacific segment was primarily impacted by changes in estimates on three projects. On one project (the project in Malaysia described above), we increased our estimated cost at completion by approximately $66.0 million in the six months ended June 30, 2013, primarily due to delays resulting from direct and indirect impacts of the equipment modification problems during the final commissioning stage of the major pipe-lay systems upgrade to the NO 105 and the other factors described above. We also benefited from reduced estimated costs during contract close-out of approximately $14 million during the three-month period ended March 31, 2013, primarily due to efficiencies associated with marine campaigns on two our EPCI projects, both of which were completed in the six-month period ended June 30, 2013.

The Middle East segment was impacted by changes in estimates on the EPCI project in Saudi Arabia discussed above. On that project, we increased our estimated cost at completion by approximately $43.0 million in the six months ended June 30, 2013, primarily as a result of revisions to the project’s execution plan, increases in our estimated cost to complete due to an extended offshore hookup campaign requiring multiple vessel mobilizations and, to a lesser extent, delays in the completion of onshore activities. While the project recognized losses in the three months ended June 30, 2013, it remains in an overall profitable position.

The Americas segment was impacted by changes in estimates on one fabrication project in Morgan City. On that project, we recognized approximately $14.0 million of incremental project losses in the six months ended June 30, 2013, primarily due to lower than expected labor productivity. This project was completed during the year ended December 31, 2013.

Loss Contingencies

Loss Contingencies

We record liabilities for loss contingencies when it is probable that a liability has been incurred and the amount of loss is reasonably estimable. We provide disclosure when there is a reasonable possibility that the ultimate loss will exceed the recorded provision or if such loss is not reasonably estimable. We are currently involved in litigation and other proceedings, as discussed in Note 10. We have accrued our estimates of the probable losses associated with these matters, and associated legal costs are generally recognized in selling, general and administrative expenses as incurred. However, our losses are typically resolved over long periods of time and are often difficult to estimate due to various factors, including the possibility of multiple actions by third parties. Therefore, it is possible future earnings could be affected by changes in our estimates related to these matters.

Cash and Cash Equivalents

Cash and Cash Equivalents

Our cash and cash equivalents are highly liquid investments with maturities of three months or less when we purchase them. We record cash and cash equivalents as restricted when we are unable to freely use such cash and cash equivalents for our general operating purposes. A majority of our restricted cash and cash equivalents represents collateralizing letters of credit as further discussed in Note 3.

Investments

Investments

We classify investments available for current operations as current assets in the accompanying balance sheets, and we classify investments held for long-term purposes as noncurrent assets. We adjust the amortized cost of debt securities for amortization of premiums and accretion of discounts to maturity. That amortization is included in interest income. We include realized gains and losses on our investments in other income (expense)—net. The cost of securities sold is based on the specific identification method. We include interest earned on securities in interest income.

Investments in Unconsolidated Affiliates

Investments in Unconsolidated Affiliates

We generally use the equity method of accounting for affiliates in which our investment ownership ranges from 20% to 50%, and in which we do not exercise control over the entity. Currently, most of our investments in affiliates that are not consolidated are recorded using the equity method.

Accounts Receivable

Accounts Receivable

Accounts Receivable—Trade, Net

A summary of contract receivables is as follows:

	June 30, 2014			December 31, 2013
	(In thousands)
Contract receivables:
Contracts in progress	$	121,920		$	192,745
Completed contracts		42,743			77,248
Retainages		85,587			127,698
Unbilled		4,303			14,571
Less allowances		(29,094	)		(30,404	)
Accounts receivable—trade, net	$	225,459		$	381,858

We expect to invoice our unbilled receivables once certain milestones or other metrics are reached, and we expect to collect all unbilled amounts. We believe that our provision for losses on uncollectible accounts receivable is adequate for our credit loss exposure.

Contract retainages generally represent amounts withheld by our customers until project completion, in accordance with the terms of the applicable contracts. The following is a summary of retainages on our contracts:

	June 30, 2014		December 31, 2013
	(In thousands)
Retainages expected to be collected within one year	$	85,587	$	127,698
Retainages expected to be collected after one year		145,883		65,365
Total retainages	$	231,470	$	193,063

We have included in accounts receivable—trade, net, retainages expected to be collected within one year.

Accounts Receivable—Other

A summary of accounts receivable— other is as follows:

	June 30, 2014		December 31, 2013
	(In thousands)
Receivables from unconsolidated affiliates	$	18,207	$	36,181
Other taxes receivable		23,678		14,934
Accrued unbilled revenue		13,219		15,696
Asset derivatives		5,055		11,641
Employee receivables		3,973		4,532
Other		8,215		6,289
Accounts receivables – other	$	72,347	$	89,273

Employee receivables are expected to be collected within 12 months, and any allowance for doubtful accounts on our accounts receivable—other is based on our estimate of the amount of probable losses due to the inability to collect these amounts (based on historical collection experience and other available information). As of June 30, 2014 and December 31, 2013, no such allowance for doubtful accounts was recorded.

Contracts in Progress and Advance Billings on Contracts

Contracts in Progress and Advance Billings on Contracts

Fair Value of Financial Instruments

Fair Value of Financial Instruments

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 an orderly transaction between market participants at the measurement date. An established hierarchy for inputs is used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors that market participants would use in valuing the asset or liability.

Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

• Level 1—inputs are based upon quoted prices for identical instruments traded in active markets.

• Level 2—inputs are based upon quoted prices for similar instruments in active markets, quoted prices for similar or identical instruments in inactive markets and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets and liabilities.

• Level 3—inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar valuation techniques.

The carrying amounts that we have reported for financial instruments, including cash and cash equivalents, accounts receivables and accounts payable approximate their fair values. See Note 6 for additional information regarding fair value measurements.

Derivative Financial Instruments

Derivative Financial Instruments

Our worldwide operations give rise to exposure to changes in certain market conditions, which may adversely impact our financial performance. When we deem it appropriate, we use derivatives as a risk management tool to mitigate the potential impacts of certain market risks. The primary market risk we manage through the use of derivative instruments is movement in foreign currency exchange rates. We use foreign currency derivative contracts to reduce the impact of changes in foreign currency exchange rates on our operating results. We use these instruments to hedge our exposure associated with revenues and/or costs on our long-term contracts and other cash flow exposures that are denominated in currencies other than our operating entities’ functional currencies. We do not hold or issue financial instruments for trading or other speculative purposes.

In certain cases, contracts with our customers contain provisions under which some payments from our customers are denominated in U.S. Dollars and other payments are denominated in a foreign currency. In general, the payments denominated in a foreign currency are designed to compensate us for costs that we expect to incur in such foreign currency. In these cases, we may use derivative instruments to reduce the risks associated with foreign currency exchange rate fluctuations arising from differences in timing of our foreign currency cash inflows and outflows. See Note 5 for additional information regarding derivative financial instruments.

Foreign Currency Translation

Foreign Currency Translation

We translate assets and liabilities of our foreign operations, other than operations in highly inflationary economies, into U.S. Dollars at period-end exchange rates, and we translate income statement items at average exchange rates for the periods presented. We record adjustments resulting from the translation of foreign currency financial statements as a component of accumulated other comprehensive income (loss) (“AOCI”), net of tax.

Earnings per Share

Earnings per Share

We have computed earnings per common share on the basis of the weighted average number of common shares, and, where dilutive, common share equivalents, outstanding during the indicated periods. See Note 8 for our earnings per share computations.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. This ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. It also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 is effective for us for annual and interim reporting periods beginning after December 15, 2016, with early application not permitted. We have the choice to apply it either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying it at the date of initial application (January 1, 2017) and not adjusting comparative information. We are currently evaluating the requirements of this ASU and have not yet determined its impact on our consolidated financial statements.

In July 2013, FASB issued an update to the topic Income Taxes. The update clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if settlement is required or expected in the event the uncertain tax position is disallowed. In situations where these items are not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the applicable jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The update is effective for 2014, and the adoption of this update did not have a material impact on our condensed consolidated financial statements.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

NOTE 5—DERIVATIVE FINANCIAL INSTRUMENTS

We enter into derivative financial instruments primarily to hedge certain firm purchase commitments and forecasted transactions denominated in foreign currencies. We record these contracts at fair value on our condensed consolidated balance sheets. Depending on the hedge designation at the inception of the contract, the related gains and losses on these contracts are either: (1) deferred as a component of AOCI until the hedged item is recognized in earnings; (2) offset against the change in fair value of the hedged firm commitment through earnings; or (3) recognized immediately in earnings. At inception and on an ongoing basis, we assess the hedging relationship to determine its effectiveness in offsetting changes in cash flows or fair value attributable to the hedged risk. We exclude from our assessment of effectiveness the portion of the fair value of the forward contracts attributable to the difference between spot exchange rates and forward exchange rates. The ineffective portion of a derivative’s change in fair value and any portion excluded from the assessment of effectiveness are immediately recognized in earnings. Gains and losses on derivative financial instruments that are immediately recognized in earnings are included as a component of gain (loss) on foreign currency-net in our condensed consolidated statements of operations.

As of June 30, 2014, the majority of our foreign currency forward contracts were designated as cash flow hedging instruments. In addition, we deferred approximately $30.1 million of net losses on these derivative financial instruments in AOCI, and we expect to reclassify approximately $30.2 million of deferred losses out of AOCI by October 2017, as hedged items are recognized. The notional value of our outstanding derivative contracts totaled $1.0 billion at June 30, 2014, with maturities extending through 2017. Of this amount, approximately $735.0 million is associated with various foreign currency expenditures we expect to incur on one of our Asia Pacific segment EPCI projects. These instruments consist of contracts to purchase or sell foreign-denominated currencies. As of June 30, 2014, the fair value of these contracts was in a net liability position totaling $2.6 million. The fair value of outstanding derivative instruments is determined using observable financial market inputs, such as quoted market prices, and is classified as Level 2 in nature.

Compensation And Retirement Disclosure [Abstract]

PENSION PLANS

NOTE 4—PENSION PLANS

Although we currently provide retirement benefits for most of our U.S. employees through sponsorship of the McDermott Thrift Plan, some of our longer-term U.S. employees and former employees are entitled to retirement benefits under the McDermott (U.S.) Retirement Plan, a non-contributory qualified defined benefit pension plan (the “McDermott Plan”), and several non-qualified supplemental defined benefit pension plans. The McDermott Plan and the non-qualified supplemental defined benefit pension plans are collectively referred to herein as the “Domestic Plans.” The McDermott Plan has been closed to new participants since 2006, and benefit accruals were frozen completely in 2010.

We also sponsor a defined benefit pension plan established under the laws of the Commonwealth of the Bahamas, the J. Ray McDermott, S.A. Third Country National Employees Pension Plan (the “TCN Plan”), which provides retirement benefits for certain of our current and former foreign employees. Effective August 1, 2011, new entry into the TCN Plan was closed, and effective December 31, 2011, benefit accruals under the TCN Plan were frozen. Effective January 1, 2012, we established a new global defined contribution plan to provide retirement benefits to non-U.S. expatriate employees who may have otherwise obtained benefits under the TCN Plan.

Retirement benefits under the McDermott Plan and the TCN Plan are generally based on final average compensation and years of service, subject to the applicable freeze in benefit accruals under the plans. Our funding policy is to fund the plans as recommended by the respective plan actuaries and in accordance with the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or other applicable law. The Pension Protection Act of 2006 (“PPA”) amended ERISA and modified the funding requirements for certain defined benefit pension plans including the McDermott Plan. Funding provisions under the PPA accelerated funding requirements are applicable to the McDermott Plan to ensure full funding of benefits accrued.

Net periodic (benefit) cost for the Domestic Plans and the TCN Plan includes the following components:

Approximately 2.9 million and 3.0 million shares underlying outstanding stock-based awards were excluded from the computation of diluted earnings per share because they were anti-dilutive for the three months and six months ended June 30, 2014, respectively. Approximately 2.9 million shares underlying outstanding stock-based awards were excluded from the computation of diluted earnings per share because they were anti-dilutive for the three months and six months ended June 30, 2013.

Potential dilutive common shares for the settlement of the common stock purchase contracts totaling 40.9 million and 20.4 million shares were considered in the calculation of diluted weighted-average shares for three months and six months ended June 30, 2014, respectively; however, due to our net loss position, they have not been reflected above because they would be anti-dilutive.

⁽¹⁾  Various U.S. equities and other investments managed under mutual funds

⁽²⁾  Asset-backed and mortgage-backed securities with maturities of up to 26 years

Our Level 2 investments consist primarily of commercial paper, asset-backed commercial paper notes backed by a pool of mortgage-backed securities and mutual funds. The fair value of our Level 2 investments was determined using a market approach which is based on quoted prices and other information for similar or identical instruments.

Our Level 3 investment consists of asset-backed commercial paper notes backed by a pool of mortgage-backed securities. The fair value of this Level 3 investment was based on the calculation of an overall weighted-average valuation, using the prices of the underlying individual securities. Individual securities in the pool were valued based on market observed prices, where available. If market prices were not available, prices of similar securities backed by similar assets were used.

Changes in Level 3 Instrument

The following is a summary of the changes in our Level 3 instrument measured on a recurring basis for the three months and six months ended June 30, 2014 and June 30, 2013:

	Three Months Ended June 30,					Six Months Ended June 30,

Unrealized Gains and Losses on Investments

Our net unrealized gain on investments was $0.2 million as of June 30, 2014. During the year ended December 31, 2013, we recognized other than temporary impairment of $1.6 million on the asset-backed securities and collateralized mortgage obligations. Our net unrealized gain on investments was $0.2 million as of December 31, 2013. The amount of investments in an unrealized loss position for less than twelve months was not significant for either of the periods presented.

Other Financial Instruments

We used the following methods and assumptions in estimating our fair value disclosures for our other financial instruments:

Cash and cash equivalents and restricted cash and cash equivalents. The carrying amounts that we have reported in the accompanying condensed consolidated balance sheets for cash, cash equivalents and restricted cash and cash equivalents approximate their fair values and are classified as Level 1 within the fair value hierarchy.

Short-term and long-term debt. The fair value of debt instruments is classified as Level 2 within the fair value hierarchy and is valued using a market approach based on quoted prices for similar instruments traded in active markets. Where quoted prices are not available, the income approach is used to value these instruments based on the present value of future cash flows discounted at estimated borrowing rates for similar debt instruments or on estimated prices based on current yields for debt issues of similar quality and terms.

Forward contracts. The fair value of forward contracts is classified as Level 2 within the fair value hierarchy and is valued using observable market parameters for similar instruments traded in active markets. Where quoted prices are not available, the income approach is used to value forward contracts, which discounts future cash flows based on current market expectations and credit risk.

The estimated fair values of certain of our financial instruments are as follows:

	June 30, 2014						December 31, 2013
	Carrying Amount			Fair Value			Carrying Amount			Fair Value
	(In thousands)
Balance Sheet Instruments
Cash and cash equivalents	$	764,034		$	764,034		$	118,702		$	118,702

STOCK-BASED COMPENSATION

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

STOCK-BASED COMPENSATION

NOTE 7—STOCK-BASED COMPENSATION

Equity instruments are measured at fair value on the grant date. Stock-based compensation expense is generally recognized on a straight-line basis over the requisite service periods of the awards. Compensation expense is based on awards we expect to ultimately vest. Therefore, we have reduced compensation expense for estimated forfeitures based on our historical forfeiture rates. Our estimate of forfeitures is determined at the grant date and is revised if our actual forfeiture rate is materially different from our estimate.

We use a Black-Scholes model to determine the fair value of certain share-based awards, such as stock options. Additionally, we use a Monte Carlo model to determine the fair value of certain share-based awards that contain market and performance-based conditions. The use of these models requires highly subjective assumptions, such as assumptions about the expected life of the award, vesting probability, expected dividend yield and the volatility of our stock price.

Total stock-based compensation expense, net recognized for the three months ended June 30, 2014 and June 30, 2013 is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2013		2014		2013
	(In thousands)
Stock Options	$	441	$	1,170	$	1,121	$	2,200
Restricted Stock Units		4,586		3,250		7,965		4,987
Performance Shares		217		1,767		545		2,923
Total	$	5,244	$	6,187	$	9,631	$	10,110

Included in stock-based compensation expense, net is a $0.7 million reversal of prior recognized expense resulting from corporate severance arrangements and other personnel-related costs recorded in Restructuring Expenses.

Segment Reporting [Abstract]

SEGMENT REPORTING

NOTE 9—SEGMENT REPORTING

In March 2014, we changed our organizational structure to orient around our offshore and subsea business activities through four primary geographic regions. The four geographic regions, which we consider to be our operating segments, consist of Asia Pacific, Americas, Middle East, and North Sea and Africa. The Caspian is no longer considered an operating segment and will continue to be aggregated in the Middle East reporting segment. The North Sea and Africa operating segment is also aggregated into the Middle East reporting segment due to the proximity of regions and similarities in the nature of services provided, economic characteristics and oversight responsibilities. Accordingly, we continue to report financial results under reporting segments consisting of Asia Pacific, Americas and the Middle East. We also report certain corporate and other non-operating activities under the heading “Corporate and other.” “Corporate and other” primarily reflects corporate personnel and activities, incentive compensation programs and other costs, which are generally fully allocated to our operating segments. The only corporate costs currently not being allocated to our operating segments are the restructuring costs associated with our corporate reorganization.

Reporting segments are measured based on operating income, which is defined as revenues reduced by total costs and expenses and equity in income (loss) of unconsolidated affiliates. Summarized financial information is shown in the following tables:

LONG-TERM DEBT AND NOTES PAYABLE

NOTE 3—LONG-TERM DEBT AND NOTES PAYABLE

During April 2014, we refinanced our existing obligations, and replaced in its entirety, our then existing $950.0 million credit agreement (the “Former Credit Agreement”) with a new credit agreement (the “New Credit Agreement”), which provides for:

• a $400.0 million first-lien, first-out three-year letter of credit facility (the “LC Facility”); and

• a $300.0 million first-lien, second-out five-year term loan (the “Term Loan”).

Additionally, during April 2014, we completed the following new financing transactions:

• the issuance of $500.0 million of second-lien seven-year senior secured notes.

• the issuance of $287.5 million of tangible equity units composed of (1) three-year amortizing, senior unsecured notes, in an aggregate principal amount of $47.5 million, and (2) prepaid common stock purchase contracts.

With the completion of these financing transactions in April 2014, we terminated the bridge loan commitment we had obtained from an affiliate of Goldman, Sachs, & Co. (“Goldman Sachs”). As a result of the termination of the bridge loan commitment, the fee we previously paid to Goldman Sachs to obtain the bridge loan commitment was recognized as interest expense in the quarter ended June 30, 2014. Due to the replacement of the Former Credit Agreement, the unamortized issuance fees related to the Former Credit Agreement were also recognized as interest expense in the quarter ended June 30, 2014. The total additional interest expense related to these items was approximately $28.0 million in the quarter ended June 30, 2014.

The Former Credit Agreement provided for revolving credit borrowings and issuances of letters of credit in an aggregate outstanding amount of up to $950.0 million. Proceeds from borrowings under the Former Credit Agreement were available for working capital needs and other general corporate purposes. At December 31, 2013, there were no borrowings outstanding, and letters of credit issued under the Former Credit Agreement totaled $214.3 million. At December 31, 2013, there was $735.7 million available for borrowings or to meet letter of credit requirements under the Former Credit Agreement. During the year ended December 31, 2013, our outstanding borrowings under the Former Credit Agreement did not exceed $80.0 million, and we had average outstanding borrowings under the Former Credit Agreement of approximately $23.5 million, with an average interest rate of 2.28%. In addition, at December 31, 2013, we had $96.9 million in outstanding unsecured bilateral letters of credit. At March 31, 2014, there was $250.0 million of revolving credit borrowings outstanding under the Former Credit Agreement, all of which were repaid during April 2014.

New Credit Facilities

The indebtedness and other obligations under the New Credit Agreement are guaranteed by substantially all of our material, wholly owned subsidiaries, other than our captive insurance subsidiary (collectively, the “Guarantors”). In connection with the New Credit Agreement, we paid certain fees to the lenders thereunder, as well as certain arrangement fees to the arrangers and agents for the New Credit Agreement, which we have capitalized and are amortizing to interest expense over the respective terms of the LC Facility and the Term Loan. We also paid certain fees to the initial purchasers of the senior secured notes and to the underwriter of the tangible equity units referred to below, which we have capitalized and are amortizing to interest expense over the respective terms of the related indebtedness.

LC Facility

The LC Facility provides for an initial letter of credit capacity of $400.0 million and allows for uncommitted increases in capacity of $100.0 million through December 31, 2014 and an additional $100.0 million thereafter, potentially increasing the total capacity to $600.0 million through the term of the LC Facility. Letters of credit issuable under the LC Facility support the obligations of McDermott and its affiliates and joint ventures. The aggregate amount of the LC Facility available for financial letters of credit is capped at 25% of the total LC Facility. As of June 30, 2014, letters of credit issued under the LC Facility totaled $225.3 million, including financial letters of credit of $3.2 million.

The LC Facility is secured on a first-lien, first-out basis (with relative priority over the Term Loan) by pledges of the capital stock of all the Guarantors and mortgages on, or other security interests in, substantially all the tangible and intangible assets of our company and the Guarantors, subject to specific exceptions.

The LC Facility contains various customary affirmative covenants, as well as specific affirmative covenants, including specific reporting requirements and a requirement for ongoing periodic financial reviews by a financial advisor. The LC Facility also requires compliance with various negative covenants, including limitations with respect to the incurrence of other indebtedness and liens, restrictions on acquisitions, capital expenditures and other investments, restrictions on sale/leaseback transactions and restrictions on prepayments of other indebtedness.

The LC Facility requires us to generate consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) of at least certain specified amounts over the term of the facility. The LC Facility also requires us to maintain a ratio of fair market value of vessel collateral to the sum of (1) the outstanding principal amount of the Term Loan, (2) the aggregate amount of undrawn financial letters of credit outstanding under the LC Facility, (3) all drawn but unreimbursed letters of credit under the LC Facility, and (4) mark-to-market foreign exchange exposure that is not cash secured of at least 1.20:1.00. The LC Facility also specifies maximum capital expenditures over the term of the facility and requires us to maintain at least $200.0 million of minimum available cash, at the end of each quarter. We were in compliance with the covenants under the LC Facility as of June 30, 2014.

The LC Facility provides for a commitment fee of 0.50% per year on the unused portion of the LC Facility and letter of credit fees at an annual rate of 2.25% for performance letters of credit and 4.50% for financial letters of credit, as well as customary issuance fees and other fees and expenses.

In addition, the LC Facility permits us to deposit up to $300.0 million with letter of credit issuers to cash collateralize letters of credit. As of June 30, 2014, we had approximately $163.4 million of letters of credit supported by cash collateral that was included in restricted cash and cash equivalents.

Term Loan

The Term Loan is secured on a first-lien, second-out basis (with the LC Facility having relative priority over the Term Loan) by pledges of the capital stock of all the Guarantors and mortgages on, or other security interests in, substantially all tangible and intangible assets of our company and the Guarantors, subject to specific exceptions. As of June 30, 2014, there was $300.0 million in borrowings outstanding under the Term Loan agreement, of which $3.0 million was classified as current notes payable.

The Term Loan requires mandatory prepayments from: (1) the proceeds from the sale of assets, as well as insurance proceeds, in each case subject to certain exceptions, to the extent such proceeds are not reinvested in our business within 365 days of receipt; (2) net cash proceeds from the incurrence of indebtedness not otherwise permitted under the New Credit Agreement; and (3) 50% of amounts deemed to be “excess cash flow,” subject to specified adjustments. The Term Loan also requires quarterly amortization payments equal to $750,000. The Term Loan also provides for a prepayment premium if we prepay or re-price the Term Loan prior to April 16, 2015.

The Term Loan requires compliance with various customary affirmative and negative covenants. We must also maintain a ratio of “ownership adjusted fair market value” of marine vessels to the sum of (1) the outstanding principal amount of the Term Loan and (2) the aggregate principal amount of unreimbursed drawings and advances under the LC Facility of at least 1.75:1.00. As of June 30, 2014, we were in compliance with all the covenants under the Term Loan.

The Term Loan was incurred with 25 basis points of original issue discount and bears interest at a floating rate, which can be, at our option, either: (1) a LIBOR rate for a specified interest period (subject to a LIBOR “floor” of 1.00%) plus an applicable margin of 4.25%; or (2) an alternate base rate (subject to a base rate “floor” of 2.00%) plus an applicable margin of 3.25%.

Senior Notes

During April 2014 we issued $500.0 million in aggregate principal amount of 8.000% senior secured notes due 2021 (the “Notes”) in a private placement in accordance with Rule 144A and Regulation S under the Securities Act of 1933, as amended. Interest on the Notes is payable semi-annually in arrears on May 1 and November 1 of each year, beginning on November 1, 2014, at an annual rate of 8%. The Notes are scheduled to mature on May 1, 2021. As of June 30, 2014, there was $500.0 million of Senior Notes outstanding.

The Notes are unconditionally guaranteed on a senior secured basis by the Guarantors, and the Notes are secured on a second—lien basis by pledges of capital stock of certain of our subsidiaries and mortgages and other security interests covering (1) specified marine vessels owned by certain of the Guarantors and (2) substantially all the other tangible and intangible assets of our company and the Guarantors, subject to exceptions for certain assets.

At any time or from time to time on or after May 1, 2017, at our option, we may redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, together with accrued and unpaid interest to the redemption date, if redeemed during the 12-month period beginning May 1 of the years indicated:

Year	Percentage
2017		104	%
2018		102	%
2019 and thereafter		100	%

The Indenture governing the Notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to: (1) incur or guarantee additional indebtedness or issue preferred stock; (2) make investments or certain other restricted payments; (3) pay dividends or distributions on capital stock or purchase or redeem subordinated indebtedness; (4) sell assets; (5) create restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us; (6) create certain liens; (7) sell all or substantially all of our assets or merge or consolidate with or into other companies; (8) enter into transactions with affiliates; and (9) create unrestricted subsidiaries. Many of those covenants would become suspended if the Notes were to attain an investment grade rating from both Moody’s Investors Service, Inc. and Standard and Poor’s Ratings Services and no default has occurred. The covenants mentioned above are subject to a number of important exceptions and limitations.

Tangible Equity Units

During April 2014, we issued 11,500,000 6.25% tangible equity units (“Units”), each with a stated amount of $25.00. Each Unit consists of (1) a prepaid common stock purchase contract and (2) a senior amortizing note due April 1, 2017 (each an “Amortizing Note”) that has an initial principal amount of $4.1266 per Amortizing Note, bears interest at a rate of 7.75% per annum and has a final scheduled installment payment date of April 1, 2017.

The prepaid common stock purchase contracts were accounted for as additional paid-in capital totaling $240.0 million. The Amortizing Notes were recorded as long-term debt totaling $47.5 million, of which $14.5 million was classified as current notes payable.

Each prepaid common stock purchase contract will automatically settle on April 1, 2017, unless settled earlier: (1) at the holder’s option, upon which we will deliver shares of our common stock, based on the applicable settlement rate and applicable market value of our stock as determined under the purchase contract; or (2) at our option, upon which we will deliver shares of our common stock, based upon the stated maximum settlement rate of 3.5562 shares per Unit, subject to adjustment. Potential dilutive common shares for the settlement of the common stock purchase contracts totaled 40.9 million at June 30, 2014, based on that maximum number of shares issuable per Unit. The potential minimum number of shares issuable is 33.4 million, which represents 2.9030 per Unit. The maximum and minimum settlement rates for the Units are subject to adjustment for certain dilutive events.

North Ocean Financing

North Ocean 105

On September 30, 2010, MII, as guarantor, and North Ocean 105 AS, in which we have a 75% ownership interest, as borrower, entered into a financing agreement to finance a portion of the construction costs of the North Ocean 105. The agreement provides for borrowings of up to $69.4 million, bearing interest at 2.76% per year, and requires principal repayment in 17 consecutive semi-annual installments, which commenced on October 1, 2012. Borrowings under the agreement are secured by, among other things, a pledge of all of the equity of North Ocean 105 AS, a mortgage on the North Ocean 105, and a lien on substantially all of the other assets of North Ocean 105 AS. MII unconditionally guaranteed all amounts to be borrowed under the agreement. As of June 30, 2014 and December 31, 2013, there was $53.1 million and $57.2 million, respectively, in borrowings outstanding under this agreement, of which (as of each date) approximately $8.2 million was classified as current notes payable.

North Ocean 102

In December 2009, J. Ray McDermott, S.A. (“JRMSA”), a wholly owned subsidiary of MII, entered into a vessel-owning joint venture transaction with Oceanteam ASA. JRMSA had guaranteed approximately 50% of this debt based on its ownership percentages in the vessel-owning companies. The outstanding debt bore interest at a rate equal to the three-month LIBOR (which was subject to reset every three months) plus a margin of 3.315%. JRMSA paid in full the approximately $31.4 million notes payable balance upon maturity during January 2014. JRMSA expects to exercise its option to purchase Oceanteam ASA’s 50% ownership interest in the vessel-owing companies in December 2014. As of December 31, 2013 we reported a consolidated notes payable of $31.4 million on our consolidated balance sheet, all of which was classified as current notes payable and paid in full in early 2014.

Unsecured Bilateral Letters of Credit and Bank Guarantees

In 2012, McDermott Middle East, Inc, and MII executed a general reimbursement agreement in favor of a bank located in the UAE relating to issuances of bank guarantees in support of contracting activities in the Middle East and India. As of June 30, 2014 and December 31, 2013, bank guarantees issued under these arrangements totaled $50.4 million and $55.8 million, respectively. In 2007 and in 2012, JRMSA and MII executed general unsecured reimbursement agreements in favor of three institutions that were lenders under the Former Credit Agreement relating to issuances of letters of credit in support of contracting activities, primarily in Asia and the Middle East. Letters of credit issued under two of these arrangements have either been replaced by letters of credit under the LC Facility or cash collateralized. The letters of credit issued under these arrangements totaled $12.0 million and $39.8 million as of June 30, 2014 and December 31, 2013, respectively.

On April 20, 2012, McDermott and one of its wholly owned subsidiaries, McDermott Australia Pty. Ltd. (“McDermott Australia”), entered into a secured Letter of Credit Reimbursement Agreement (the “Reimbursement Agreement”) with Australia and New Zealand Banking Group Limited (“ANZ”). In accordance with the terms of the Reimbursement Agreement, ANZ issued letters of credit in the aggregate amount of approximately $109.0 million to support McDermott Australia’s performance obligations under contractual arrangements relating to a field development project. The obligations of McDermott and McDermott Australia under the Reimbursement Agreement are secured by McDermott Australia’s interest in the contractual arrangements and certain related assets. During six months ended June 30, 2014, we replaced these letters of credit with letters of credit under the LC Facility.

Surety Bonds

In 2012 and 2011, MII executed general agreements of indemnity in favor of surety underwriters based in Mexico relating to surety bonds issued in support of contracting activities of J. Ray McDermott de Mèxico, S.A. de C.V. and McDermott, Inc, both subsidiaries of MII. As of June 30, 2014 and December 31, 2013, bonds issued under these arrangements totaled $42.1 million and $43.5 million, respectively. In October 2013, MII executed general agreements of indemnity in favor of surety underwriters relating to surety bonds in support of vessels operating in Brazil. The project requiring these bonds was completed during the quarter allowing us to cancel the outstanding bonds. Accordingly, as of June 30, 2014, there were no bonds issued under these arrangements. As of December 31, 2013, the bonds issued under these arrangements totaled $106.3 million.
