NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF MAJOR ACCOUNTING POLICIES

Basis of Presentation. Oceaneering International, Inc. ("Oceaneering," "we" or "us") has prepared these unaudited consolidated financial statements pursuant to instructions for quarterly reports on Form 10-Q, which we are required to file with the U.S. Securities and Exchange Commission (the "SEC"). These financial statements do not include all information and footnotes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). These financial statements reflect all adjustments that we believe are necessary to present fairly our financial position as of June 30, 2018 and our results of operations and cash flows for the periods presented. Except as otherwise disclosed herein, all such adjustments are of a normal and recurring nature. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2017. The results for interim periods are not necessarily indicative of annual results.

Principles of Consolidation. The consolidated financial statements include the accounts of Oceaneering and our 50% or more owned and controlled subsidiaries. We also consolidate entities that are determined to be variable interest entities if we determine that we are the primary beneficiary; otherwise, we account for those entities using the equity method of accounting. We use the equity method to account for our investments in unconsolidated affiliated companies of which we own an equity interest of between 20% and 50% and as to which we have significant influence, but not control, over operations. We use the cost method for all other long-term investments. Investments in entities that we do not consolidate are reflected on our balance sheet in Other non-current assets. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents. Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less from the date of investment.

Accounts Receivable – Allowances for Doubtful Accounts. We determine the need for allowances for doubtful accounts using the specific identification method. We generally do not require collateral from our customers.

Inventory. Inventory is valued at the lower of cost or net realizable value. We determine cost using the weighted-average method.

Property and Equipment and Long-Lived Intangible Assets. We provide for depreciation of property and equipment on the straight-line method over their estimated useful lives. We charge the costs of repair and maintenance of property and equipment to operations as incurred, while we capitalize the costs of improvements that extend asset lives or functionality. Upon the disposition of property and equipment, the related cost and accumulated depreciation accounts are relieved and any resulting gain or loss is included as an adjustment to cost of services and products.

Intangible assets, primarily acquired in connection with business combinations, include trade names, intellectual property and customer relationships and are being amortized over their estimated useful lives.

We capitalize interest on assets where the construction period is anticipated to be more than three months. We capitalized $1.8 million and $1.2 million of interest in the three-month periods ended June 30, 2018 and 2017, respectively, and $3.4 million and $2.2 million of interest in the six-month periods ended June 30, 2018 and 2017, respectively. We do not allocate general administrative costs to capital projects.

Our management periodically, and upon the occurrence of a triggering event, reviews the realizability of our property and equipment and long-lived intangible assets to determine whether any events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. For long-lived assets to be held and used, we base our evaluation on impairment indicators, such as the nature of the assets, the future economic benefits of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether an impairment has occurred through the use of an undiscounted cash flows analysis of the asset at the lowest level for which

Table of Contents

identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. For assets held for sale or disposal, the fair value of the asset is measured using fair market value less estimated costs to sell. Assets are classified as held-for-sale when we have a plan for disposal of certain assets and those assets meet the held for sale criteria.

Business Acquisitions. We account for business combinations using the acquisition method of accounting, and, in each case, we allocate the acquisition price to the assets acquired and liabilities assumed based on their fair market values as of the date of acquisition.

In March 2018, we acquired Ecosse Subsea Limited (“Ecosse”) for $68 million in cash. Headquartered in Aberdeen, Scotland, Ecosse builds and operates seabed preparation, route clearance and trenching tools for submarine cables and pipelines on an integrated basis that includes vessels, ROVs and survey services. We have accounted for this acquisition by allocating the purchase price to the assets acquired and liabilities assumed based on their estimated fair values as of the date of acquisition. This purchase price allocation is preliminary and is subject to change upon completion of our valuation procedures. We have included Ecosse’s operations in our consolidated financial statements starting from the date of closing and its operating results are reflected in our Subsea Projects segment.

Goodwill. Annually, we are required to evaluate our goodwill by performing a qualitative or quantitative impairment test. Under the qualitative approach and after assessing the totality of events or circumstances, we determine that it is more likely than not the fair value of a reporting unit is less than its carrying amount, we are required to perform the quantitative analysis to determine the fair value. We tested the goodwill attributable to each of our reporting units for impairment as of December 31, 2017 and concluded that there was no impairment.

In addition to our annual evaluation of goodwill for impairment, upon the occurrence of a triggering event, we review our goodwill to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount.

Foreign Currency Translation. The functional currency for several of our foreign subsidiaries is the applicable local currency. Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated into U.S. dollars using the exchange rates in effect as of the balance sheet date, and the resulting translation adjustments are recognized, in accumulated other comprehensive income as a component of shareholders' equity. All foreign currency transaction gains and losses are recognized currently in the Consolidated Statements of Operations.

Revenue Recognition. On January 1, 2018, we adopted Accounting Standard Update ("ASU") 2014-09, "Revenue from Contracts with Customers," which implemented Accounting Standards Codification Topic 606 ("ASC 606"). We have used the modified retrospective method applied to those contracts which were not completed as of January 1, 2018, and have utilized the practical expedient to reflect the effect on contract modifications in the aggregate. The cumulative effect of applying ASC 606 has been recognized as an adjustment to retained earnings as of January 1, 2018. The comparative information with respect to prior periods has not been retrospectively restated and continues to be reported under the accounting standards in effect for those periods.

Table of Contents

The cumulative effect of the changes made to our Consolidated Balance Sheet as of January 1, 2018 for the adoption of ASC 606 was as follows:

Table of Contents

All of our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically, ranging from weekly to monthly. We use the input method to faithfully depict revenue recognition, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. We have used the expedient available to recognize revenue when the billing corresponds to the value realized by the customer where appropriate.

We account for significant fixed-price contracts, mainly relating to our Subsea Products segment, and to a lesser extent in our Subsea Projects and Advanced Technologies segments, by recognizing revenue over time using an input, cost-to-cost measurement percentage-of-completion method. We use the input cost-to-cost method to faithfully depict revenue recognition. This commonly used method allows appropriate calculation of progress on our contracts. A performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation.

We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by us from a customer, are excluded from revenue.

In our service-based business lines, which principally charge on a day rate basis for services provided, there is no significant impact in the pattern of revenue and profit recognition as a result of implementation of ASC 606. In our product-based business lines, we expect impacts on the pattern of our revenue and profit recognition in our contracts using the percentage-of-completion method, as a result of the requirement to exclude uninstalled materials and significant inefficiencies from the measure of progress. This is most likely to occur in our Subsea Products segment.

We apply judgment in the determination and allocation of transaction price to performance obligations, and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, where required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. In prior years, we have recorded adjustments to earnings as a result of revisions to contract estimates. We always strive to estimate our contract costs and profitability accurately. However, there could be significant adjustments to overall contract costs in the future, due to changes in facts and circumstances.

In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms.

Please see Note 2 — "Revenue" — for more information on our revenue from contracts with customers.

New Accounting Standards. In January 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-01, "Financial Instruments — Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities." This update:


•	requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value, with changes in fair value recognized in net income; and


•	provides an expedient for the valuation and impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify value and impairment — when a qualitative assessment indicates that an impairment exists, an entity is required to measure the investment at fair value.

Table of Contents

ASU No. 2016-01 was effective for us beginning on January 1, 2018, and we have utilized the expedient for valuing equity investments without readily determinable fair values. This update has not had a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, "Leases." This update requires reporting entities to separate the lease components from the non-lease components in a contract and recognize lease assets and lease liabilities on the balance sheet for substantially all lease arrangements. ASU No. 2016-02 will become effective for us beginning January 1, 2019.

We have formed a project team, which has completed its planning work and has an initial view of the work required relevant to the standard. This plan is expected to enable us to complete all of the required work to assess our position, create the necessary policy, procedures and controls and calculate the effect of applying ASU 2016-02 as of the date of initial application in line with the timeline and requirements of the ASU. We expect to be able to provide a qualitative assessment of the effects of the impacts of ASU 2016-02 on our existing contracts later this year.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740) – Intra-Entity Transfers of Assets Other than Inventory." Previously, U.S. GAAP generally prohibited the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset was sold to an outside party. The amendments in this update eliminate the exception for an intra-entity transfer of an asset other than inventory. Two common examples of assets included within the scope of this update are intellectual property and property, plant and equipment. The exception for an intra-entity transfer of inventory will remain in place. The amendments in this update were effective for us beginning January 1, 2018. This ASU has not had a material effect on our consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, "Income Statement – Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the December 2017 enactment of U.S. tax reform legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this update also require certain disclosures about stranded tax effects. The amendments in this update will become effective for us beginning January 1, 2019, and early adoption is permitted. We do not anticipate that this ASU will have a material effect on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, "Compensation – Stock Compensation (Topic 718) Improvements to Nonemployee Share-Based Payment Accounting." This ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this ASU will become effective for us beginning January 1, 2019, and early adoption is permitted. We do not anticipate that this ASU will have a material effect on our consolidated financial statements.

Contract Balances

Our contracts with milestone payments have, in the aggregate, a significant impact on the contract asset and the contract liability balances. Milestones are contractually agreed with customers and relate to significant events across the contract lives. Some milestones are achieved before revenue is recognized, resulting in a contract liability, other milestones are achieved after revenue is recognized resulting in a contract asset.

The following table provides information about contract assets, and contract liabilities from contracts with customers.



(in thousands)	Jun 30, 2018		Jan 1, 2018
Contract assets	$	168,464	$	171,956
Contract liabilities	30,137		37,590

Table of Contents

Our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition.

During the six months ended June 30, 2018, Contract assets decreased by $3.5 million from its opening balance due to billings of $877 million, which exceeded accrued revenue of $874 million. Contract liabilities decreased $7.5 million from its opening balance, due to revenue recognition of $21.9 million (from the opening balance) less deferrals of milestone payments that totaled $14.4 million. There were no cancellations, impairments or other significant impacts in the period that relate to other categories of explanation.

Performance Obligations

As of June 30, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $295 million. We expect to recognize revenue for the remaining performance obligations of $247 million over the next twelve months.

The aggregate amount of transaction price allocated to remaining performance obligations that were unsatisfied (or partially unsatisfied) as of June 30, 2018 are noted above. In arriving at this value, we have used two expedients available to us and are not disclosing amounts in relation to performance obligations: (1) that are part of contracts with an original expected duration of one year or less; or (2) on contracts where we recognize revenue in line with the billing.

Due to the nature of our service contracts in our Remotely Operated Vehicle, Subsea Projects, Asset Integrity and Advanced Technologies segments, the majority of our contracts either have initial contract terms of one year or less or have customer option cancellation clauses that lead us to consider the original expected duration of one year or less.

In our Subsea Products and Advanced Technologies segments, we have long-term contracts that extend beyond one year, and these make up the majority of the balance reported. We also have shorter-term product contracts with an expected original duration of one year or less that have been excluded.

Where appropriate, we have made estimates within the transaction price of elements of variable consideration within the contracts and constrained those amounts to a level where we consider that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The amount of revenue recognized in the six months ended June 30, 2018, which was associated with performance obligations completed or partially completed in prior periods was not significant.

As of June 30, 2018, there was no outstanding liability balance for refunds or returns due to the nature of our contracts and the goods and services we provide. Our warranties are limited to assurance warranties that are of a standard length and are not considered to be a material right. The majority of our contracts consist of a single performance obligation. When there are multiple obligations, we look for observable evidence of stand-alone selling prices on which to base the allocation. This involves judgment as to the appropriateness of the observable evidence relating to the facts and circumstances of the contract. If we do not have observable evidence, we estimate stand-alone selling prices by taking a cost plus margin approach, using typical margins from the type of product or service, customer and regional geography involved.

Costs to Obtain or Fulfill a Contract

In line with the available expedient, we capitalize costs to obtain a contract when those amounts are significant and the contract is expected at inception to exceed one year in duration; otherwise, the costs are expensed in the period when incurred. Costs to obtain a contract primarily consist of bid and proposal costs, which are incremental to our fixed costs. There was no balance or amortization of Costs to obtain a contract in the current reporting period.

Costs to fulfill a contract primarily consist of certain mobilization costs incurred to provide products or services to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of Costs to fulfill a contract as of June 30, 2018 was $14.3 million, with $1.2 million and $2.5 million of

amortization for the three- and six-month periods ended June 30, 2018, respectively. No impairment costs were recognized.

Unamortized debt issuance costs		(8,367		)	(4,698		)
Revolving Credit Facility		—			—
Long-term Debt		$	782,228		$	792,312

In November 2014, we completed the public offering of $500 million aggregate principal amount of 4.650% Senior Notes due 2024 (the "2024 Senior Notes"). We pay interest on the 2024 Senior Notes on May 15 and November 15 of each year. The 2024 Senior Notes are scheduled to mature on November 15, 2024.

In February 2018, we completed the public offering of $300 million aggregate principal amount of 6.000% Senior Notes due 2028 (the "2028 Senior Notes"). We will pay interest on the 2028 Senior Notes on February 1 and August 1 of each year, beginning on August 1, 2018. The 2028 Senior Notes are scheduled to mature on February 1, 2028.

We may redeem some or all of the 2024 Senior Notes and the 2028 Senior Notes (collectively, the "Senior Notes") at specified redemption prices. We used the net proceeds from the 2028 Senior Notes to repay our term loan indebtedness described further below.

In October 2014, we entered into a credit agreement (as amended, the "Credit Agreement") with a group of banks. The Credit Agreement provided for a $500 million five-year revolving credit facility (the "Revolving Credit Facility"). Subject to certain conditions, the aggregate commitments under the Revolving Credit Facility may be increased by up to $300 million at any time upon agreement between us and existing or additional lenders. Borrowings under the Revolving Credit Facility may be used for general corporate purposes. The Credit Agreement also provided for a $300 million term loan (the "Term Loan Facility"), which we repaid in full in February 2018, using net proceeds from the issuance of our 2028 Senior Notes referred to above, and cash on hand.

In February 2018, we entered into Agreement and Amendment No. 4 to Credit Agreement ("Amendment No. 4"). Amendment No. 4 amended the Credit Agreement to, among other things, extend the maturity of the Revolving Credit Facility to January 25, 2023 with the extending Lenders, which represent 90% of the existing commitments of the Lenders, such that the total commitments for the Revolving Credit Facility will be $500 million until October 25, 2021, and thereafter $450 million until January 25, 2023.

Table of Contents

Borrowings under the Revolving Credit Facility bear interest at an Adjusted Base Rate or the Eurodollar Rate (both as defined in the Credit Agreement), at our option, plus an applicable margin based on our Leverage Ratio (as defined in the Credit Agreement) and, at our election, based on the ratings of our senior unsecured debt by designated ratings services, thereafter to be based on such debt ratings. The applicable margin varies: (1) in the case of advances bearing interest at the Adjusted Base Rate, from 0.125% to 0.750% for borrowings under the Revolving Credit Facility; and (2) in the case of advances bearing interest at the Eurodollar Rate, from 1.125% to 1.750%. The Adjusted Base Rate is the highest of (1) the per annum rate established by the administrative agent as its prime rate, (2) the federal funds rate plus 0.50% and (3) the daily one-month LIBOR plus 1%. We pay a commitment fee ranging from 0.125% to 0.300% on the unused portion of the Revolving Credit Facility, depending on our Leverage Ratio. The commitment fees are included as interest expense in our consolidated financial statements.

The Credit Agreement contains various covenants that we believe are customary for agreements of this nature, including, but not limited to, restrictions on our ability and the ability of each of our subsidiaries to incur debt, grant liens, make certain investments, make distributions, merge or consolidate, sell assets and enter into certain restrictive agreements. We are also subject to a maximum adjusted total Capitalization Ratio (as defined in the Credit Agreement) of 55%. The Credit Agreement includes customary events of default and associated remedies. As of June 30, 2018, we were in compliance with all the covenants set forth in the Credit Agreement.

We have two interest rate swaps in place on a total of $200 million of the 2024 Senior Notes for the period to November 2024. Please refer to Note 5 — "Commitments and Contingencies" — for more information on our interest rate swaps.

We incurred $6.9 million and $4.1 million of issuance costs related to the 2024 Senior Notes and the 2028 Senior Notes, respectively, and $2.6 million of loan costs, including costs of the amendments prior to Amendment No. 4, related to the Credit Agreement. The costs, net of accumulated amortization, are included as a reduction of Long-term Debt in our Consolidated Balance Sheet, as it pertains to the Senior Notes, and in Other non-current assets, as it pertains to the Credit Agreement. We are amortizing these costs to Interest expense through the maturity date for the Senior Notes and to January 2023 for the Credit Agreement.

5. COMMITMENTS AND CONTINGENCIES

Litigation. In the ordinary course of business, we are subject to actions for damages alleging personal injury under the general maritime laws of the United States, including the Jones Act, for alleged negligence. We report actions for personal injury to our insurance carriers and believe that the settlement or disposition of those claims will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Various other actions and claims are pending against us, most of which are covered by insurance. Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not materially affect our results of operations, cash flows or financial position.

Financial Instruments and Risk Concentration. In the normal course of business, we manage risks associated with foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions. As a matter of policy, we do not use derivative instruments unless we have an underlying exposure. Other financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents and accounts receivable.

The carrying values of cash and cash equivalents approximate their fair values due to the short-term maturity of the underlying instruments. Accounts receivable are generated from a broad group of customers, primarily from within the energy industry, which is our major source of revenue. Due to their short-term nature, carrying values of our accounts receivable and accounts payable approximate fair market values.

We estimated the aggregate fair market value of the Senior Notes to be $783 million as of June 30, 2018, based on quoted prices. Since the market for the Senior Notes is not an active market, the fair value of the Senior Notes is classified within Level 2 in the fair value hierarchy under U.S. GAAP (inputs other than quoted prices in active markets for similar assets and liabilities that are observable or can be corroborated by observable market data for substantially the full terms for the assets or liabilities).

Table of Contents

We have two interest rate swaps in place on a total of $200 million of the 2024 Senior Notes for the period to November 2024. The agreements swap the fixed interest rate of 4.650% on $100 million of the 2024 Senior Notes to the floating rate of one month LIBOR plus 2.426% and on another $100 million to one month LIBOR plus 2.823%. We estimate the combined fair value of the interest rate swaps to be a net liability of $9.4 million as of June 30, 2018, which is included on our balance sheet in our Other Long-term Liabilities. These values were arrived at based on a discounted cash flow model using Level 2 inputs.

Since the second quarter of 2015, the exchange rate for the Angolan kwanza relative to the U.S. dollar generally has been declining, although the exchange rate was relatively stable during 2017. As our functional currency in Angola is the U.S. dollar, we recorded foreign currency transaction losses related to the kwanza of $4.8 million and $12.4 million in the three- and six-month periods ended June 30, 2018, respectively, as a component of Other income (expense), net in our Consolidated Statements of Operations for those respective periods. Our foreign currency transaction gains or losses related primarily to the remeasurement of our Angolan kwanza cash balances to U.S. dollars. Conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola, and the central bank has slowed this process since mid-2015, causing our kwanza cash balances to subsequently increase. As of June 30, 2018 and December 31, 2017, we had the equivalent of approximately $12 million and $27 million of kwanza cash balances, respectively, in Angola reflected on our balance sheet.

To mitigate our currency exposure risk in Angola, we have used kwanza to purchase equivalent Angolan central bank (Banco Nacional de Angola) bonds. The bonds are denominated as U.S. dollar equivalents, so that, upon payment of semi-annual interest and principal upon maturity, payment is made in kwanza, equivalent to the respective U.S. dollars at the then-current exchange rate. Our intention was to hold the bonds to maturity, and to reinvest funds from maturing bonds in similar long-term assets. We previously believed the chance of selling the bonds before maturity and repatriating cash out of Angola was remote. However, in the second quarter of 2018, $10 million of bonds matured which we reinvested in similar long-term assets. Additionally, we sold $23 million of bonds prior to their maturity date. As a result, we have changed our accounting for these bonds from held-to-maturity securities to available-for-sale securities, as we intend to sell the bonds if we are able to repatriate the proceeds. As of June 30, 2018, we have classified $31 million of bonds due to mature in the next twelve months as Other current assets and $15 million of bonds due to mature after twelve months as Other non-current assets on our Consolidated Balance Sheet, with $5 million maturing in 2020 and $10 million maturing in 2023. During the second quarter of 2018, we were able to repatriate $31 million of cash from Angola.

We estimated the fair market value of the Angolan bonds to be approximately $46 million as of June 30, 2018 using quoted prices. Since the market for the Angolan bonds is not an active market, the fair value of the Angolan bonds is classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of June 30, 2018, we have not recorded the difference between the fair market value and carrying amount of the outstanding bonds through the Consolidated Statement of Comprehensive Income (Loss) due to the insignificance of the difference between the fair market value and the carrying amount of the bonds.

6. EARNINGS (LOSS) PER SHARE, SHARE-BASED COMPENSATION AND SHARE REPURCHASE PLAN

Earnings per Share. For each period presented, the only difference between our calculated weighted average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units. In periods where we have a net loss, the effect of our outstanding restricted stock units is anti-dilutive, and therefore does not increase our diluted shares outstanding.

For each period presented, our net income (loss) allocable to both common shareholders and diluted common shareholders is the same as our net income (loss) in our consolidated statements of operations.

Dividends. From the second quarter of 2014 through the third quarter of 2016, we paid a quarterly dividend to our common shareholders of $0.27 per share. Starting in the fourth quarter of 2016 through the third quarter 2017, we paid a dividend of $0.15 per share. Our last quarterly dividend was $0.15 per share and was declared in July 2017 and was paid in September 2017.

Share-Based Compensation. We have no outstanding stock options and, therefore, no share-based compensation to be recognized pursuant to stock option grants.

Table of Contents

During 2016, 2017 and through June 30, 2018, we granted restricted units of our common stock to certain of our key executives and employees. During 2016 through 2018, our Board of Directors granted restricted common stock to our nonemployee directors. The restricted units granted to our key executives and key employees generally vest in full on the third anniversary of the award date, conditional on continued employment. The restricted stock unit grants can vest pro rata over three years, provided the individual meets certain age and years-of-service requirements. The shares of restricted common stock we grant to our non-employee directors vest in full on the first anniversary of the award date, conditional upon continued service as a director. Each grantee of shares of restricted stock is deemed to be the record owner of those shares during the restriction period, with the right to vote and receive any dividends on those shares. The restricted stock units outstanding have no voting or dividend rights.

For each of the restricted stock units granted in 2016 through June 30, 2018, at the earlier of three years after grant or at termination of employment or service, the grantee will be issued one share of our common stock for each unit vested. As of June 30, 2018 and December 31, 2017, respective totals of 1,489,893 and 1,181,805 shares of restricted stock or restricted stock units were outstanding.

We estimate that share-based compensation cost not yet recognized related to shares of restricted stock or restricted stock units, based on their grant-date fair values, was $16 million as of June 30, 2018. This expense is being recognized on a staged-vesting basis over three years for awards attributable to individuals meeting certain age and years-of-service requirements, and on a straight-line basis over the applicable vesting period of one or three years for the other awards.

Share Repurchase Plan. In December 2014, our Board of Directors approved a plan to repurchase up to 10 million shares of our common stock. Under this plan, we had repurchased 2.0 million shares of our common stock for $100 million through December 31, 2017. We did not repurchase any shares under the plan during the six-month period ended June 30, 2018. We account for the shares we hold in treasury under the cost method, at average cost.

7. INCOME TAXES

In December 2017, the United States enacted the Tax Act, which included a number of changes to existing U.S. tax laws that have an impact on our income tax provision, most notably a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent for tax years beginning after December 31, 2017, and the creation of a territorial tax system with a one-time mandatory tax on applicable previously deferred earnings of foreign subsidiaries. We recognized the income tax effects of the Tax Act in our financial statements for the year ended December 31, 2017 in accordance with Staff Accounting Bulletin No. 118 (“SAB 118”), which provided SEC staff guidance for the application of accounting standards for income taxes in the reporting period in which the Tax Act was enacted. As such, our financial results reflected provisional amounts for those specific income tax effects of the Tax Act for which the accounting was incomplete but a reasonable estimate could be determined. The final determination is expected to be completed and reflected in our financial statements issued for subsequent reporting periods that fall within the measurement period contemplated by SAB 118.

During the second quarter of 2018, the United States Internal Revenue Service issued Notice 2018-26, announcing its intent to issue regulations related to the application of the Section 965 one-time mandatory tax on applicable previously deferred earnings of foreign subsidiaries and potential anti-avoidance measures. Although the notice was not legally binding, we are currently reviewing whether future regulations contemplated by the notice could have any effect on the provisional amounts recorded as of December 31, 2017. Subsequently, on August 1, 2018, the United States Internal Revenue Service issued Proposed Regulations providing guidance regarding Section 965 of the Internal Revenue Code as amended by the Tax Act. We are currently reviewing the proposed regulations and will evaluate any impact on our estimated provisional tax during the third quarter of 2018.

During interim periods, we provide for income taxes based on our current estimated annual effective tax rate using assumptions as to (1) earnings and other factors that would affect the tax provision for the remainder of the year and (2) the operations of foreign branches and subsidiaries that are subject to local income and withholding taxes. In the six-month period ended June 30, 2018, we recognized additional tax expense of $3.6 million from discrete items, primarily related to $1.8 million of excess tax deficiencies on share-based compensation awards and $1.3 million of additional uncertain tax position.

The effective tax rate for the six months ended June 30, 2018 was different from the federal statutory rate of 21.0%, primarily due to the geographic mix of operating revenue and results that generated taxes in certain jurisdictions

Table of Contents

that exceeded the tax benefit from losses and credits in other jurisdictions, which could not be realized in the quarter due to valuation allowances being provided, and discrete items discussed above. Given the currently challenging operating environment, we continue to evaluate the realizability of recorded deferred tax assets. It is our intention to continue to indefinitely reinvest in certain of our international operations; therefore, we do not provide withholding taxes on the possible distribution of these earnings. We do not believe the effective tax rate before discrete items is meaningful, as current conditions do not allow for relevant guidance in this regard. The effective tax rate for the six months ended June 30, 2017 was lower than the federal statutory rate of 35.0%, primarily due to our intention to indefinitely reinvest in certain of our international operations, partially offset by a discrete tax item associated with share-based compensation. In 2017, we did not provide for U.S. taxes on the portion of our foreign earnings that we deemed indefinitely reinvested.

We conduct our international operations in a number of locations that have varying laws and regulations with regard to income and other taxes, some of which are subject to interpretation. We recognize the benefit for a tax position if the benefit is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement. We do not believe that the total of unrecognized tax benefits will increase or decrease significantly in the next twelve months.

We account for any applicable interest and penalties on uncertain tax positions as a component of our provision for income taxes on our financial statements. Including associated foreign tax credits and penalties and interest, we have accrued a net total of $6.8 million in Other Long-term Liabilities on our balance sheet for unrecognized tax benefits as of June 30, 2018. All additions or reductions to those liabilities would affect our effective income tax rate in the periods of change.

Our tax returns are subject to audit by taxing authorities in multiple jurisdictions. These audits often take years to complete and settle. The following lists the earliest tax years open to examination by tax authorities where we have significant operations:

We determine Income (Loss) from Operations for each business segment before interest income or expense, Other income (expense) and Provision for income taxes. We do not consider an allocation of these items to be practical. Our Equity in earnings (losses) of unconsolidated affiliates is part of our Subsea Projects segment.

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

Certain statements we make in this quarterly report on Form 10-Q are forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These statements include, without limitation, statements regarding our expectations about:


•	third quarter and the full year of 2018 operating results and the contributions from our segments to those results (including the expected benefits from a recent business acquisition, anticipated revenue, operating income or loss, and utilization information), as well as the items below the operating income (loss) line;


•	our cash flows and earnings before interest, taxes and depreciation and amortization (EBITDA) in 2018;


•	future demand, business activity levels, industry conditions and contract awards during the second half of 2018;


•	our plans for future operations (including planned additions to and retirements from our remotely operated vehicle ("ROV") fleet, our intent regarding the new multiservice subsea support vessel scheduled for delivery at the end of 2018 and expected to be placed into service during the first quarter of 2019 and other capital expenditures);


•	our future dividends;


•	the adequacy of our liquidity, cash flows and capital resources;


•	our ability and intent to redeem Angolan bonds and repatriate cash;


•	shares to be repurchased under our share repurchase plan;


•	our estimated effective tax rate;


•	the implementation of new accounting standards and related policies, procedures and controls; and


•	seasonality.

These forward-looking statements are subject to various risks, uncertainties and assumptions, including those we have referred to under the headings "Risk Factors" and "Cautionary Statement Concerning Forward-Looking Statements" in Part I of our annual report on Form 10-K for the year ended December 31, 2017. Although we believe that the expectations reflected in such forward-looking statements are reasonable, because of the inherent limitations in the forecasting process, as well as the relatively volatile nature of the industries in which we operate, we can give no assurance that those expectations will prove to have been correct. Accordingly, evaluation of our future prospects must be made with caution when relying on forward-looking information.

The following discussion should be read in conjunction with "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, 2017.

Executive Overview

Our diluted earnings (loss) per share for the three- and six-month periods ended June 30, 2018 were $(0.34) and $(0.83), respectively, including the impacts of the write-offs of certain equipment and intangible assets associated with exiting the land survey business and equipment obsolescence, as well as foreign currency exchange losses, compared to $0.02 and $(0.06) for the corresponding period of the prior year.

Our second quarter of 2018 operating results, excluding the write-offs of certain equipment and intangible assets, met our expectations and reflected profit contributions from each of our operating segments, except our Subsea Projects segment.

For the third quarter of 2018, compared to the second quarter, we are expecting an improvement in our overall operating results, based primarily on Subsea Projects' return to profitability. We expect each of our other operating segment's results to be flat to slightly down. Unallocated Expenses are expected to continue to be in the upper-$20 million range.

During the second half of 2018 relative to the first half, we expect to generate an improvement in our consolidated operating results on increased revenue, with positive EBITDA contributions from each of our operating segments. We anticipate improvements to be led by Subsea Projects and Advanced Technologies, with higher results from ROV and similar results from Subsea Products and Asset Integrity.

For 2018, although we expect that the overall offshore markets will continue to be challenging, we are encouraged by the early signs of improving activity in the offshore energy markets and in our businesses as the industry

rebounds. However, taking into account all of our segments, including Unallocated Expenses, through June 30, 2018 and our outlook for the remainder of 2018, we expect to incur an operating loss and a net loss for the full year of 2018.

Below the operating income (loss) line, we expect:


•	increased interest expense from higher overall interest rates, which affect our floating rate debt and our swaps to floating rates on $200 million of fixed-rate debt; and


•	a loss on our equity investment in Medusa Spar LLC, as volume continues to be low in current producing zones.

We are no longer providing guidance as to our 2018 annual effective tax rate before discrete items, as current conditions do not allow for relevant guidance in this regard.

During 2018, we expect positive EBITDA on a consolidated basis, as well as for each of our operating segments. Our liquidity and financial approach, focused on maintaining capital discipline and improving returns, provides optionality to broaden our service and product offerings, or deploy capital in our existing businesses.

Our Board of Directors suspended the payment of our quarterly dividend in the fourth quarter of 2017. Although we will continue to review our dividend position periodically, we do not anticipate our Board to consider reinstating a quarterly cash dividend until we see a significant improvement in our market outlook and projected free cash flow.

Critical Accounting Policies and Estimates

For information about our Critical Accounting Policies and Estimates, please refer to the discussion in our annual report on Form 10-K for the year ended December 31, 2017 under the heading "Critical Accounting Policies and Estimates" in Item 7 – "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Effective January 1, 2018, we adopted Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers." See Notes 1 and 2 of Notes to Consolidated Financial Statements included in this report for further details, including our accounting policy for Revenue Recognition under this newly adopted accounting standard.

Liquidity and Capital Resources

As of June 30, 2018, we had working capital of $687 million, including $340 million of cash and cash equivalents. Additionally, Amendment No. 4 to the Credit Agreement (as defined below) provides for a $500 million revolving credit facility until October 25, 2021 and thereafter $450 million until January 25, 2023 with a group of banks. We consider our liquidity, cash flows and capital resources to be adequate to support our existing operations and capital commitments.

Our capital expenditures were $54 million during the first six months of 2018, excluding the $68 million purchase price for the acquisition of Ecosse Subsea Limited ("Ecosse"), as compared to $41 million in the first six months of 2017. We acquired Ecosse in March 2018, reflecting our commitment to expand our service line capabilities, grow our market position within the offshore renewable energy market, and provide our customers with proven tools to optimize installation projects. Ecosse builds and operates seabed preparation, route clearance and trenching tools for submarine cables and pipelines on an integrated basis that includes vessels, ROVs and survey services.

We currently estimate our capital expenditures for 2018, excluding business acquisitions, will be in the range of $100 million to $140 million, including $60 million to $90 million of growth capital expenditures. We expect to spend $20 million in our Subsea Projects segment to complete the new-build multiservice subsea support vessel Ocean Evolution, scheduled for delivery at the end of 2018 and expected to be placed into service during the first quarter of 2019.

The Ocean Evolution is intended to be U.S.-flagged and documented with a coastwise endorsement by the U.S. Coast Guard. It is expected to have an overall length of 353 feet, a Class 2 dynamic positioning system, accommodations for 110 personnel, a helideck, a 250-ton active heave-compensated crane, and a working moonpool. We expect to outfit the vessel with two of our high specification 4,000 meter work-class ROVs. The vessel will also be equipped with a satellite communications system capable of transmitting streaming video for real-time work observation by shore-based personnel. We anticipate the vessel will be used to augment our ability

Table of Contents

to provide subsea intervention services in the U.S. Gulf of Mexico. These services are required to perform inspection, maintenance and repair projects and hardware installations.

We previously had several deepwater vessels under long-term charter. The last of our long-term deepwater vessel charters expired in March 2018. With the current market conditions, we attempt to charter vessels for specific projects on a back-to-back basis with the vessel owners. We also charter vessels on a short-term basis as necessary to augment our fleet.

In Angola, the Ocean Intervention III is expected to end its work scope for our customer on July 31, 2018, following our customer’s commitment to exercise two one-month optional extension periods provided for under the field support vessel services contract. At the conclusion of the vessel work, the vessel will be returned to the owner. Pursuant to our field support services contract, we will continue to supply project management and engineering services to the customer through January 2019.

As of June 30, 2018, we had long-term debt in the principal amount of $800 million outstanding and $500 million available under our revolving credit facility provided under the Credit Agreement. None of our outstanding debt is scheduled to mature before November 2024.

In October 2014, we entered into a credit agreement (as amended, the "Credit Agreement") with a group of banks. The Credit Agreement provided for a $500 million five-year revolving credit facility (the "Revolving Credit Facility"). Subject to certain conditions, the aggregate commitments under the Revolving Credit Facility may be increased by up to $300 million at any time upon agreement between us and existing or additional lenders. Borrowings under the Revolving Credit Facility may be used for general corporate purposes. The Credit Agreement also provided for a $300 million term loan, which we repaid in full in February 2018, using net proceeds from the issuance of our 6.000% Senior Notes due 2028 (the "2028 Senior Notes") described further below, and cash on hand.

In February 2018, we entered into Agreement and Amendment No. 4 to the Credit Agreement ("Amendment No. 4").

Amendment No. 4 amended the Credit Agreement to, among other things, extend the maturity of the Revolving Credit Facility to January 25, 2023 with the extending Lenders, which represent 90% of the existing commitments of the Lenders, such that the total commitments for the Revolving Credit Facility will be $500 million until October 25, 2021, and thereafter $450 million until January 25, 2023.

Borrowings under the Credit Agreement bear interest at an Adjusted Base Rate or the Eurodollar Rate (both as defined in the Credit Agreement), at our option, plus an applicable margin based on our Leverage Ratio (as defined in the Credit Agreement) and, at our election, based on the ratings of our senior unsecured debt by designated ratings services, thereafter to be based on such debt ratings. The applicable margin varies: (1) in the case of advances bearing interest at the Adjusted Base Rate, from 0.125% to 0.750%; and (2) in the case of advances bearing interest at the Eurodollar Rate, from 1.125% to 1.750%. The Adjusted Base Rate is the highest of (1) the per annum rate established by the administrative agent as its prime rate, (2) the federal funds rate plus 0.50% and (3) the daily one-month LIBOR plus 1%. We pay a commitment fee ranging from 0.125% to 0.300% on the unused portion of the Revolving Credit Facility, depending on our Leverage Ratio. The commitment fees are included as interest expense in our consolidated financial statements.

In November 2014, we completed the public offering of $500 million aggregate principal amount of 4.650% due 2024 (the "2024 Senior Notes"). We pay interest on the 2024 Senior Notes on May 15 and November 15 of each year. The 2024 Senior Notes are scheduled to mature on November 15, 2024.

In February 2018, we completed the public offering of the 2028 Senior Notes. We pay interest on the 2028 Senior Notes on February 1 and August 1 of each year, beginning on August 1, 2018. The 2028 Senior Notes are scheduled to mature on February 1, 2028. We may redeem some or all of the 2024 Senior Notes and 2028 Senior Notes at specified redemption prices.

Our principal source of cash from operating activities is our net income (loss), adjusted for the non-cash effects of, among other things, depreciation and amortization, deferred income taxes and noncash compensation under our share-based compensation plans. Our $16 million and $103 million of cash provided from operating activities in the six-month periods ended June 30, 2018 and 2017, respectively, were principally affected by operating results and cash increases (decreases) of:


•	$(12) million and $23 million, respectively, from changes in accounts receivable; and


•	$4 million and $(25) million, respectively, from changes in current liabilities.

The decrease in cash related to accounts receivable in the six months ended June 30, 2018, reflected higher business levels in June 2018 as compared to December of 2017. Conversely, we had an increase in cash related to accounts receivable in the six months ended June 30, 2017, as we had lower revenue in the quarter ended June 30, 2017 as compared to the fourth quarter of 2016, so, combined with our cash collections, our overall accounts receivable balances decreased. The 2017 decrease in cash related to changes in current liabilities reflected generally lower business levels.

In the six months ended June 30, 2018, we used $95 million of cash in investing activities, mainly related to capital expenditures of $54 million and the Ecosse acquisition of $68 million. Additionally, we had proceeds of $33 million from Angola bonds, resulting from a maturity and redemptions, partially offset by a purchase of $10 million of Angola bonds. We also used $6 million in financing activities, mainly as a result of the repayment of the Term Loan Facility of $300 million, substantially offset by the net proceeds from the issuance of the 2028 Senior Notes, net of issuance costs, of $296 million. In the six months ended June 30, 2017, we used $40 million of cash in investing activities, primarily related to capital expenditures of $41 million. We also used $32 million in financing activities, primarily for the payment of cash dividends of $29 million.

We have not guaranteed any debt not reflected on our consolidated balance sheet as of June 30, 2018, and we do not have any off-balance sheet arrangements, as defined by SEC rules.

In December 2014, our Board of Directors approved a plan to repurchase up to 10 million shares of our common stock. In 2015, we repurchased 2.0 million shares of our common stock for $100 million under this plan. We did not repurchase any shares during 2016 through June 30, 2018. We account for the shares we hold in treasury under the cost method, at average cost. The timing and amount of any future repurchases will be determined by our management. We expect that any additional shares repurchased under the plan will be held as treasury stock for possible future use. The plan does not obligate us to repurchase any particular number of shares.

From the second quarter of 2014 through the third quarter of 2016, we paid a quarterly dividend to our common shareholders of $0.27 per share. Starting in the fourth quarter of 2016 through the third quarter of 2017, we paid a dividend of $0.15 per share. Our last quarterly dividend was declared in July 2017 at $0.15 per share and paid in September 2017. Subsequently, the Board suspended the payment of a quarterly dividend. Although we will continue to review our dividend position periodically, we do not anticipate our Board to consider reinstating a quarterly cash dividend until we see a significant improvement in our market outlook and projected free cash flow.

Results of Operations

We operate in five business segments. The segments are contained within two businesses — services and products provided primarily to the offshore energy industry ("Energy Services and Products") and services and products provided to non-energy industries ("Advanced Technologies"). Our Unallocated Expenses are those not associated with a specific business segment.

Consolidated revenue and profitability information is as follows:

For 2018, although we expect that overall the offshore markets will continue to be challenging, we are encouraged by the early signs of improving activity in those markets and in our businesses, as the industry rebounds. However, taking into account all of our segments, including Unallocated Expenses, through June 30, 2018 and our outlook for the remainder of 2018, we expect to incur an operating loss and a net loss for the full year of 2018.

Seasonality

In our Subsea Projects segment, we generate a material amount of our consolidated revenue from contracts for services in the U.S. Gulf of Mexico, which has historically been more active from April through October, as compared to the rest of the year. The European operations of our Asset Integrity segment have historically been more active in the second and third quarters. However, the reduced customer spending levels in the current commodity price environment have substantially obscured this seasonality since mid-2014. Revenue in our ROV segment is generally subject to seasonal variations in demand, with our first quarter typically being the lower quarter of the year. The level of our ROV seasonality primarily depends on the number of ROVs we have engaged in vessel-based subsea infrastructure inspection, maintenance and repair and installation, which is more seasonal than drilling support. Periods since mid-2014 reflect an exception, as there has been a general decline in offshore activity, which caused a decrease in our ROV days on hire and utilization. Revenue in our Subsea Products and Advanced Technologies segments generally has not been seasonal.

Energy Services and Products

The primary focus of our Energy Services and Products business over the last several years has been toward increasing our asset base and capabilities for providing services and products for offshore energy operations and subsea completions. In recent years, we have focused on increasing our service and product offerings toward our energy customers' operating expenditures and the offshore renewable energy market.

The following table sets forth the Revenue, Margin and Operating Income (Loss) for our Energy Services and Products business segments for the periods indicated. In the ROV section of the table that follows, "Days available" includes all days from the first day that an ROV is placed into service until the ROV is retired. All days during this period are considered available days, including periods when an ROV is undergoing maintenance or repairs. Our ROVs do not have scheduled maintenance or repair that requires significant time when the ROVs are not available for utilization.

In general, our energy related business focuses on supplying services and products to the offshore energy market. During the downturn in oil prices since mid-2014, we have experienced lower activity levels and reduced pricing. In 2018, with oil prices stabilizing and activity in some areas improving, a foundation for a turnaround in the offshore energy industry appears to be building.

We believe we are the world's largest provider of ROV services, and this business segment historically, but not currently, has been the largest contributor to our Energy Services and Products business operating income. Our ROV segment revenue reflects the utilization percentages, fleet sizes and average pricing of the respective periods. Our ROV operating margins have declined as depreciation has become a higher percentage of revenue as we have experienced lower utilization and pricing in recent years. In the full year of 2015, 2016 and 2017, ROV depreciation and amortization was 18%, 27% and 29% of ROV revenue, respectively; and in the six-month period ended June 30, 2018, it was 29% of ROV revenue.

Table of Contents

During the second quarter of 2018, ROV operating income increased compared to the immediately preceding quarter, mainly due to higher seasonal activity for vessel-based services and an increase in the number of working floating rigs for which we provide drill support services. Revenue grew 26% on a 24% increase in days on hire sequentially during the second quarter of 2018, as our fleet utilization improved to 54% from 44%, mostly attributable to increased international activity. Our average revenue per day on hire was essentially flat compared to the immediately preceding quarter. We added four new ROVs to our fleet during the six months ended June 30, 2018 and retired four, resulting in a total of 279 ROVs in our fleet size as of June 30, 2018 .

Our ROV operating income decreased in the three- and six-month periods ended June 30, 2018 compared to the corresponding periods of the prior year, mainly due to lower average revenue per day on hire in 2018, as a result of a shift in geographic mix and market conditions, and higher average daily costs associated with reactivating and mobilizing ROVs, partially offset by an increase in utilization.

We expect our third quarter 2018 ROV operating results to be similar to that of the second quarter results. For the full year 2018, we continue to project increased days on hire, as we maintain or slightly shift our 2018 fleet mix towards drill-support utilization.

Our Subsea Products segment consists of two business units: (1) manufactured products; and (2) service and rental. Manufactured products includes production control umbilicals and specialty subsea hardware, while service and rental includes tooling, subsea work systems and installation and workover control systems. The following table presents revenue from manufactured products and service and rental, as their respective percentages of total Subsea Products revenue:



	Three Months Ended						Six Months Ended
	Jun 30, 2018		Jun 30, 2017		Mar 31, 2018		Jun 30, 2018		Jun 30, 2017
Manufactured products	50	%	70	%	59	%	55	%	71	%

Service and rental	50	%	30	%	41	%	45	%	29	%

Subsea Products operating income in the second quarter of 2018 increased slightly compared to that of the immediately preceding quarter, largely attributable to an increase in demand for our service and rental business and the timing of awards, partially offset by reduced throughput in our manufactured products and the write-offs of certain equipment. Our Subsea Products operating income decreased in the three- and six-month periods ended June 30, 2018 compared to the corresponding periods of the prior year, mainly due to lower demand in manufactured products and the write-offs of certain equipment, partially offset by an improvement in execution.

Our Subsea Products backlog was $245 million as of June 30, 2018, compared to $276 million as of December 31, 2017. The backlog decline was largely attributable to manufactured products' umbilical order intake. We expect Subsea Products operating results to decline slightly in the third quarter of 2018 compared to the second quarter. During the second half of 2018, we anticipate Subsea Products operating results to be similar to the first half of 2018. We expect increased manufacturing activity levels on the execution of lower margin projects. We anticipate operating margins to be in the low-single digit range until we see an increase in the Subsea Products' backlog and pricing. We still expect an increase in contract awards during the second half of 2018, which should result in a Subsea Products book-to-bill ratio exceeding 1.0 for the full year.

Our Subsea Projects operating results decreased in the three-month period ended June 30, 2018 compared to the immediately preceding quarter, driven by lower-than-anticipated margins on certain projects, timing of projects moving into the second half of the year, and a continued competitive price environment for diving and deepwater vessel services in the U.S. Gulf of Mexico. Additionally, the decrease related to second quarter 2018 write-offs of certain equipment and intangible assets associated with exiting the land survey business and equipment obsolescence.

Our Subsea Projects operating results declined in the three- and six-month periods ended June 30, 2018 compared to the corresponding periods of the prior year, due to lower pricing, lower vessel demand as a result of the completion of the Island Pride vessel working offshore India in the fourth quarter of 2017, reduced diving work in Angola, and the write-offs of equipment and intangible assets in the second quarter of 2018. In the third quarter of 2018, we expect Subsea Projects operating results to return to profitability compared to the second quarter, mainly

Table of Contents

driven by an increase in utilization in the U.S. Gulf of Mexico deepwater vessel and diving services, the anticipated contribution from the Ecosse acquisition and the absence of the second quarter 2018 write-offs of certain equipment and intangible assets, partially offset by lower projected vessel related activity in Angola. For the full year of 2018 compared to 2017, we expect lower Subsea Projects operating results due to decreased vessel demand as a result of the completion of the Island Pride vessel working offshore India in the fourth quarter of 2017, reduced diving work in Angola and the second quarter 2018 write-offs of certain equipment and intangible assets.

Asset Integrity's operating income in the three-month period ended June 30, 2018 compared to the immediately preceding quarter improved on higher revenue, due to the traditional seasonal increase in the demand for inspection services. For the three- and six-month periods ended June 30, 2018, compared to the corresponding periods of the prior year, Asset Integrity's operating income did not change significantly. For the third quarter of 2018, we expect Asset Integrity's operating income to be flat to slightly down compared to the second quarter. For the full year of 2018, we project Asset Integrity operating results to be relatively flat compared to 2017.

(dollars in thousands)	Jun 30, 2018			Jun 30, 2017			Mar 31, 2018			Jun 30, 2018			Jun 30, 2017

Operating Income %	8		%	7		%	2		%	5		%	7		%

Advanced Technologies operating income in the second quarter of 2018 was higher than that of the immediately preceding quarter, predominantly due to increased government-related work and modestly improved results in the commercial business. Operating income for the three-month period ended June 30, 2018 was flat compared to the corresponding period of the prior year. The operating income for the six-month period ended June 30, 2018 was lower than that of the corresponding period of the prior year, due to execution issues in our Automated Guided Vehicles ("AGV") business, partially offset by increased activity in the theme park business. We expect our Advanced Technologies operating income in the third quarter of 2018 to be flat compared to the second quarter. For the full year of 2018, we continue to anticipate Advanced Technologies operating income to be higher due to increased activity from backlog in our commercial theme park business and improved results within our AGV business.

Unallocated Expenses

Our Unallocated Expenses, (i.e., those not associated with a specific business segment), within gross profit consist of expenses related to our incentive and deferred compensation plans, including restricted stock units, performance units and bonuses, as well as other general expenses. Our Unallocated Expenses within operating income consist of those expenses within gross profit plus general and administrative expenses related to corporate functions.

The following table sets forth our Unallocated Expenses for the periods indicated.



	Three Months Ended									Six Months Ended
(dollars in thousands)	Jun 30, 2018			Jun 30, 2017			Mar 31, 2018			Jun 30, 2018		Jun 30, 2017

Operating income % of revenue	6		%	5		%	7		%	6	%	5	%

Our Unallocated Expenses for the three-month period ended June 30, 2018 were relatively flat compared to the corresponding period of the prior year and the immediately preceding quarter. Our Unallocated Expenses for the six-month period ended June 30, 2018 increased compared to the corresponding period of the prior year, primarily due to higher Information Technology-related corporate expenses. For the remainder of 2018, we expect our quarterly Unallocated Expenses to be in the upper-$20 million range.

In addition to interest on borrowings, interest expense includes amortization of loan costs, fees for lender commitments under our revolving credit agreement and fees for standby letters of credit and bank guarantees that banks issue on our behalf for performance bonds, bid bonds and self-insurance requirements.

Foreign currency transaction gains and losses are the principal component of Other income (expense), net. In the three- and six-month periods ended June 30, 2018, we incurred foreign currency transaction losses of $3.4 million and $11.7 million, respectively. The currency losses in 2018 primarily related to the Angolan kwanza and its declining exchange rate relative to the U.S. dollar, and related primarily to our cash balances in Angola. Conversion of cash balances from Angolan kwanza to U.S. dollars is controlled by the central bank in Angola, and the central bank slowed this process starting in mid-2015, causing our cash balances in kwanza to increase. However, during the three months ended June 30, 2018, we were able to repatriate $31 million of cash out of Angola.

The provisions for income taxes were related to our current estimated annual effective tax rate using assumptions as to (1) earnings and other factors that would affect the tax provision for the remainder of the year and (2) the operations of foreign branches and subsidiaries that are subject to local income and withholding taxes. Factors that could affect our estimated tax rate include our profitability levels in general and the geographic mix in the sources of our results. The effective tax rate for the six months ended June 30, 2018 was different than the federal statutory rate of 21% primarily due to the geographic mix of operating revenue and results that generated taxes in certain jurisdictions that exceeded the tax benefit from losses and credits in other jurisdictions, which could not be realized in the quarter due to valuation allowances being provided, and discrete items primarily related to the accounting for share-based compensation and uncertain tax positions. Given the currently challenging operating environment, we continue to evaluate the realizability of recorded deferred tax assets. It is our intention to continue to indefinitely reinvest in certain of our international operations, therefore, we do not provide withholding taxes on the possible distribution of these earnings. We do not believe the effective tax rate before discrete items is meaningful, as current conditions do not allow for relevant guidance in this regard. The effective tax rate for the six months ended June 30, 2017 was lower than the statutory rate of 35%, primarily due to our intention to indefinitely reinvest in certain of our international operations and discrete items related to the accounting for share-based compensation. In 2017, we did not provide for U.S. taxes on the portion of our foreign earnings that we deemed indefinitely reinvested.

Item 3.	Quantitative and Qualitative Disclosures About Market Risk.

We are currently exposed to certain market risks arising from transactions we have entered into in the normal course of business. These risks relate to interest rate changes and fluctuations in foreign exchange rates. Except for our exposure in Angola, we do not believe these risks are material. We have not entered into any market risk sensitive instruments for speculative or trading purposes. When we have a significant amount of borrowings, we typically manage our exposure to interest rate changes through the use of a combination of fixed- and floating-rate debt. See Note 4 of Notes to Consolidated Financial Statements included in this report for a description of our revolving credit facility and interest rates on our borrowings. We have two interest rate swaps in place on a total of $200 million of the 2024 Senior Notes. The agreements swap the fixed interest rate of 4.650% on $100 million of the 2024 Senior Notes to the floating rate of one month LIBOR plus 2.426% and on another $100 million to one month LIBOR plus 2.823%. We believe significant interest rate changes would not have a material near-term impact on our future earnings or cash flows.

Because we operate in various oil and gas exploration and production regions in the world, we conduct a portion of our business in currencies other than the U.S. dollar. The functional currency for several of our international operations is the applicable local currency. A stronger U.S. dollar against the U.K. pound sterling, the Norwegian kroner and the Brazilian real may result in lower operating income. We manage our exposure to changes in foreign exchange rates principally through arranging compensation in U.S. dollars or freely convertible currency and, to the extent possible, by limiting compensation received in other currencies to amounts necessary to meet obligations denominated in those currencies. We use the exchange rates in effect as of the balance sheet date to translate assets and liabilities as to which the functional currency is the local currency, resulting in translation adjustments that we reflect as accumulated other comprehensive income or loss in the equity section of our Consolidated Balance Sheets. We recorded net adjustments to our equity accounts of $(15.6) million and $3.7 million in the six-month periods ended June 30, 2018 and 2017, respectively. Negative adjustments reflect the net impact of the strengthening of the U.S. dollar against various foreign currencies for locations where the functional currency is not the U.S. dollar. Conversely, positive adjustments reflect the effect of a weakening U.S. dollar.

We recorded foreign currency transaction losses of $3.4 million and $11.7 million in the three- and six-month periods ended June 30, 2018, respectively. Those losses are included in Other income (expense), net in our Consolidated Statements of Operations in those respective periods. Since the second quarter of 2015, the exchange rate for the Angolan kwanza relative to the U.S. dollar generally has been declining, although the exchange rate was relatively stable during 2017. As our functional currency in Angola is the U.S. dollar, we recorded foreign currency transaction losses related to the kwanza of $4.8 million and $12.4 million in the three- and six-month periods ended June 30, 2018, as a component of Other income (expense), net in our Consolidated Statements of Operations for those respective periods. Our foreign currency transaction losses related primarily to the remeasurement of our Angolan kwanza cash balances to U.S. dollars. Conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola, and the central bank has slowed this process since mid-2015, causing our kwanza cash balances to subsequently increase. As of June 30, 2018 and December 31, 2017, we had the equivalent of approximately $12 million and $27 million of kwanza cash balances in Angola, respectively, reflected on our balance sheet. Since December 31, 2017, Angola has devalued its currency by almost 50%. We will incur further foreign currency exchange losses in Angola if further currency devaluations occur.

Table of Contents

We estimated the fair market value of the Angolan bonds to be approximately $46 million as of June 30, 2018 using quoted prices. Since the market for the Angolan bonds is not an active market, the fair value of the Angolan bonds is classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of June 30, 2018, we have not recorded the difference between the fair market value and carrying amount through the Consolidated Statement of Comprehensive Income (Loss) due to the insignificance of the difference between the fair market value and the carrying amount of the bonds.

Item 4. Controls and Procedures.

In accordance with Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we carried out an evaluation, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of June 30, 2018 to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

There has been no change in our internal control over financial reporting that occurred during the three months ended June 30, 2018 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.

In the ordinary course of business, we are subject to actions for damages alleging personal injury under the general maritime laws of the United States, including the Jones Act, for alleged negligence. We report actions for personal injury to our insurance carriers and believe that the settlement or disposition of those claims will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

In the ordinary course of business, we are subject to actions for damages alleging personal injury under the general maritime laws of the United States, including the Jones Act, for alleged negligence. We report actions for personal injury to our insurance carriers and believe that the settlement or disposition of those claims will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. Various other actions and claims are pending against us, most of which are covered by insurance. Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not materially affect our results of operations, cash flows or financial position. Financial Instruments and Risk Concentration. In the normal course of business, we manage risks associated with foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions. As a matter of policy, we do not use derivative instruments unless we have an underlying exposure. Other financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents and accounts receivable. The carrying values of cash and cash equivalents approximate their fair values due to the short-term maturity of the underlying instruments. Accounts receivable are generated from a broad group of customers, primarily from within the energy industry, which is our major source of revenue. Due to their short-term nature, carrying values of our accounts receivable and accounts payable approximate fair market values. We estimated the aggregate fair market value of the Senior Notes to be $783 million as of June 30, 2018, based on quoted prices. Since the market for the Senior Notes is not an active market, the fair value of the Senior Notes is classified within Level 2 in the fair value hierarchy under U.S. GAAP (inputs other than quoted prices in active markets for similar assets and liabilities that are observable or can be corroborated by observable market data for substantially the full terms for the assets or liabilities). We have two interest rate swaps in place on a total of $200 million of the 2024 Senior Notes for the period to November 2024. The agreements swap the fixed interest rate of 4.650% on $100 million of the 2024 Senior Notes to the floating rate of one month LIBOR plus 2.426% and on another $100 million to one month LIBOR plus 2.823%. We estimate the combined fair value of the interest rate swaps to be a net liability of $9.4 million as of June 30, 2018, which is included on our balance sheet in our Other Long-term Liabilities. These values were arrived at based on a discounted cash flow model using Level 2 inputs. Since the second quarter of 2015, the exchange rate for the Angolan kwanza relative to the U.S. dollar generally has been declining, although the exchange rate was relatively stable during 2017. As our functional currency in Angola is the U.S. dollar, we recorded foreign currency transaction losses related to the kwanza of $4.8 million and $12.4 million in the three- and six-month periods ended June 30, 2018, respectively, as a component of Other income (expense), net in our Consolidated Statements of Operations for those respective periods. Our foreign currency transaction gains or losses related primarily to the remeasurement of our Angolan kwanza cash balances to U.S. dollars. Conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola, and the central bank has slowed this process since mid-2015, causing our kwanza cash balances to subsequently increase. As of June 30, 2018 and December 31, 2017, we had the equivalent of approximately $12 million and $27 million of kwanza cash balances, respectively, in Angola reflected on our balance sheet. To mitigate our currency exposure risk in Angola, we have used kwanza to purchase equivalent Angolan central bank (Banco Nacional de Angola) bonds. The bonds are denominated as U.S. dollar equivalents, so that, upon payment of semi-annual interest and principal upon maturity, payment is made in kwanza, equivalent to the respective U.S. dollars at the then-current exchange rate. Our intention was to hold the bonds to maturity, and to reinvest funds from maturing bonds in similar long-term assets. We previously believed the chance of selling the bonds before maturity and repatriating cash out of Angola was remote. However, in the second quarter of 2018, $10 million of bonds matured which we reinvested in similar long-term assets. Additionally, we sold $23 million of bonds prior to their maturity date. As a result, we have changed our accounting for these bonds from held-to-maturity securities to available-for-sale securities, as we intend to sell the bonds if we are able to repatriate the proceeds. As of June 30, 2018, we have classified $31 million of bonds due to mature in the next twelve months as Other current assets and $15 million of bonds due to mature after twelve months as Other non-current assets on our Consolidated Balance Sheet, with $5 million maturing in 2020 and $10 million maturing in 2023. During the second quarter of 2018, we were able to repatriate $31 million of cash from Angola. We estimated the fair market value of the Angolan bonds to be approximately $46 million as of June 30, 2018 using quoted prices. Since the market for the Angolan bonds is not an active market, the fair value of the Angolan bonds is classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of June 30, 2018, we have not recorded the difference between the fair market value and carrying amount of the outstanding bonds through the Consolidated Statement of Comprehensive Income (Loss) due to the insignificance of the difference between the fair market value and the carrying amount of the bonds.

Shareholders' Equity, Earnings Per Share And Stock-Based Compensation [Abstract]
Shareholders' Equity, Earnings Per Share And Stock-Based Compensation	Earnings per Share. For each period presented, the only difference between our calculated weighted average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units. In periods where we have a net loss, the effect of our outstanding restricted stock units is anti-dilutive, and therefore does not increase our diluted shares outstanding. For each period presented, our net income (loss) allocable to both common shareholders and diluted common shareholders is the same as our net income (loss) in our consolidated statements of operations. Dividends. From the second quarter of 2014 through the third quarter of 2016, we paid a quarterly dividend to our common shareholders of $0.27 per share. Starting in the fourth quarter of 2016 through the third quarter 2017, we paid a dividend of $0.15 per share. Our last quarterly dividend was $0.15 per share and was declared in July 2017 and was paid in September 2017. Share-Based Compensation. We have no outstanding stock options and, therefore, no share-based compensation to be recognized pursuant to stock option grants. During 2016, 2017 and through June 30, 2018, we granted restricted units of our common stock to certain of our key executives and employees. During 2016 through 2018, our Board of Directors granted restricted common stock to our nonemployee directors. The restricted units granted to our key executives and key employees generally vest in full on the third anniversary of the award date, conditional on continued employment. The restricted stock unit grants can vest pro rata over three years, provided the individual meets certain age and years-of-service requirements. The shares of restricted common stock we grant to our non-employee directors vest in full on the first anniversary of the award date, conditional upon continued service as a director. Each grantee of shares of restricted stock is deemed to be the record owner of those shares during the restriction period, with the right to vote and receive any dividends on those shares. The restricted stock units outstanding have no voting or dividend rights. For each of the restricted stock units granted in 2016 through June 30, 2018, at the earlier of three years after grant or at termination of employment or service, the grantee will be issued one share of our common stock for each unit vested. As of June 30, 2018 and December 31, 2017, respective totals of 1,489,893 and 1,181,805 shares of restricted stock or restricted stock units were outstanding. We estimate that share-based compensation cost not yet recognized related to shares of restricted stock or restricted stock units, based on their grant-date fair values, was $16 million as of June 30, 2018. This expense is being recognized on a staged-vesting basis over three years for awards attributable to individuals meeting certain age and years-of-service requirements, and on a straight-line basis over the applicable vesting period of one or three years for the other awards. Share Repurchase Plan. In December 2014, our Board of Directors approved a plan to repurchase up to 10 million shares of our common stock. Under this plan, we had repurchased 2.0 million shares of our common stock for $100 million through December 31, 2017. We did not repurchase any shares under the plan during the six-month period ended June 30, 2018. We account for the shares we hold in treasury under the cost method, at average cost.
