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 March 31, 2019 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, 2018. 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.

Reclassifications. Certain amounts from prior periods have been reclassified to conform with the current period presentation.

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 assets included in 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 $2.0 million and $1.6 million of interest in the three-month periods ended March 31, 2019 and 2018, 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

Table of Contents

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 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 tools for seabed preparation, route clearance and trenching for the installation of submarine cables and pipelines. These services are offered 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. 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, if we determine that it is more likely than not that 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 for that reporting unit. We were required to perform a quantitative analysis for our Subsea Projects Segment and determined that the fair value was less than the carrying value and, as a result, we recorded a pre-tax goodwill impairment loss of $76 million in the Subsea Projects reporting unit. The impairment loss was recorded in our Consolidated Statement of Operation for the quarter ended December 31, 2018. For the remaining reporting units, qualitative assessments were performed and we concluded that it was more likely than not the fair value of the reporting unit was more than the carrying value of the reporting unit and, therefore, no impairment was required.

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 (loss) 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 that 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 was recognized as an adjustment of $537,000 to retained earnings as of January 1, 2018.

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

Table of Contents

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, and that are collected by us from customers, 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 recorded adjustments to earnings as a result of revisions to contract estimates; however, we did not have any material adjustments during the quarter ended March 31, 2019. 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.

On January 1, 2019 we adopted Accounting Standards Update ("ASU") 2018-11, an amendment to ASU 2016-02, "Leases" (collectively, the "New Leases Standard") that: (1) requires lessees to recognize a Right-of-Use asset ("ROU assets") and lease liabilities for virtually all leases; and (2) updates previous accounting standards for lessors to align certain requirements of the New Leases Standard and the revenue recognition accounting standard. We have used the transition method allowing us to apply the new standard at the adoption date and have adopted the package of practical expedients permitting us to retain the identification and classification of leases made under the previously applicable accounting standards; we did not adopt the hindsight expedient. The cumulative effect of applying the New Leases Standard as of January 1, 2019 of $5.9 million was recognized as an adjustment to retained earnings, with corresponding adjustments to increase ROU assets and Lease liabilities by $185 million and $191 million, respectively. The standard did not materially affect our net earnings and had no impact on cash flows. 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.

As a lessee, we utilize the expedients available to us not to recognize leases of 12 months or less on the balance sheet and to combine lease and non-lease components together and account for the combined component as a lease for all asset classes, except real estate.

As a lessor, we lease certain types of equipment along with the provision of services and utilize the expedient allowing us to combine the lease and non-lease components into a combined component that is accounted for under ASC 842 where the lease component is predominant and under ASC 606 where the service component is predominant.

We determine whether a contract is or contains a lease at inception, whether as a lessee or a lessor. We take into consideration the elements of an identified asset, right to control and the receipt of economic benefit in making these determinations.

Table of Contents

As a lessee, we lease land, buildings, vessels and equipment for the operation of our business and to support some of our service line revenue streams. These generally carry lease terms that range from days for operational and support equipment to 22 years for land and buildings. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our discretion. When the exercise of those options is reasonably certain, we include them in the lease assessment. Our leases do not contain material restrictions or covenants that impact our accounting for them, nor do we provide residual value guarantees.

As a lessor, we lease certain types of equipment, often providing services at the same time. These leases can be priced on a day-rate or lump-sum basis for periods ranging from a few days to multi-year contracts. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our customers sole discretion. These leases generally do not contain options to purchase, material restrictions or covenants that impact our accounting for leases.

ROU operating lease assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, based on the information available at commencement date in determining the present value of future payments. In determining the incremental borrowing rate, we took into account our external credit ratings, bond yields for us and our identified peers, geographic regions where we operate, credit default swap rates and the impact associated with providing collateral for an amount equal to the lease payments. Our ROU operating lease assets also include any lease prepayments made and exclude lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease, which we take into account when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

We do not have any leases that have not yet commenced that create significant rights and obligations for us as a lessee nor do we have any material related party transactions.

Please see Note 5 — "Leases" — for more information on our operating leases.

New Accounting Standards. In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments, as modified by subsequently issued ASU 2018-19. The guidance introduces a new credit reserving model know as the Current Expected Credit Loss ("CECL") model, which is based on expected losses, and differs significantly from the incurred loss approach used today. The CECL model requires estimating all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. These ASUs affect an entity to varying degrees depending on the credit quality for the assets held by the entity, their duration and how the entity applies current U.S. GAAP. These ASUs will become effective for us beginning January 1, 2020. We are currently evaluating the impact of this guidance.

In August 2017, the FASB issued ASU No. 2017-12 "Derivatives and Hedging (Topic 815): Targeted improvements to Accounting for Hedging Activities," which simplified the application of hedge accounting guidance in current GAAP and improved the reporting of hedging relationships to better portray the economic results of our risk management activities in our consolidated financial statements. We adopted this ASU on January 1, 2019 and the effects of this update have not had a material impact on our consolidated financial statements.

In January 2016, the 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.

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.

Table of Contents

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 were effective for us beginning January 1, 2019. This ASU has not had 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 become effective for us beginning January 1, 2019. This ASU has not had 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.

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 three months ended March 31, 2019, Contract assets decreased by $35 million from its opening balance due to billings of $519 million, which exceeded accrued revenue of $484 million. Contract liabilities decreased $6.5 million from its opening balance, due to revenue recognition of $15 million less deferrals of milestone payments that totaled $8.2 million. There were no cancellations, impairments or other significant impacts in the period that relate to other categories of explanation.

Performance Obligations

As of March 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $364 million. We expect to recognize revenue for the remaining performance obligations of $272 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 March 31, 2019 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.

Table of Contents

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 three months ended March 31, 2019, which was associated with performance obligations completed or partially completed in prior periods was not significant.

As of March 31, 2019, there was no outstanding liability balance for refunds or returns due to the nature of our contracts and the services and products 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 services or products to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of Costs to fulfill a contract was $13 million as of both March 31, 2019 and December 31, 2018. For the three-month periods ended March 31, 2019 and 2018, $2.6 million and $1.3 million of amortization expense was recorded, respectively. No impairment costs were recognized.

Unamortized debt issuance costs		(7,548		)	(7,820		)
Revolving Credit Facility		—			—
Long-term Debt		$	790,969		$	786,580

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 pay interest on the 2028 Senior Notes on February 1 and August 1 of each year. 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 initially 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 2028 Senior Notes referred to above, and cash on hand.

Table of Contents

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 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%; 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 March 31, 2019, 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 6 — "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 on our Consolidated Balance Sheets, 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.

6. COMMITMENTS AND CONTINGENCIES

Litigation. In the ordinary course of business, we are, from time to time, involved in litigation or subject to disputes, governmental investigations 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, premises liability claims and other claims.

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 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 other dispute resolution proceedings and, in some cases, the availability and amount of potentially available 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.

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.

Table of Contents

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 $749 million as of March 31, 2019, 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 $1.5 million as of March 31, 2019, 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, with the exception that 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 less than $0.1 million and $7.7 million in the three-month periods ended March 31, 2019 and 2018, respectively, 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. Any conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola, and the central bank slowed this process from mid-2015 to 2017, causing our kwanza cash balances to increase during that period of time. However, beginning in 2018, the Angolan central bank has allowed us to repatriate cash from Angola. As of March 31, 2019 and December 31, 2018, we had the equivalent of approximately $7.7 million and $9.3 million, respectively, of kwanza cash balances 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. During 2018, we received a total of $70 million proceeds from maturities and redemptions of Angolan bonds and reinvested $10 million of the proceeds in similar assets. As of March 31, 2019 and December 31, 2018, we have $10 million of Angolan bonds on our Consolidated Balance Sheets. Because we intend to sell the bonds if we are able to repatriate the proceeds, we classified these bonds as available-for-sale securities, and they are recorded as Other current assets on our Consolidated Balance Sheets.

We estimated the fair market value of the bonds to be $10 million as of March 31, 2019 and December 31, 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 March 31, 2019 and December 31, 2018, the difference between the fair market value and the carrying amount of the Angolan bonds was immaterial.

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

Earnings (Loss) 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.

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 2017, 2018 and through March 31, 2019, we granted restricted units of our common stock to certain of our key executives and employees. During 2017, 2018 and 2019, 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 stock we grant to our non-employee directors vest in full on the first anniversary of the award date, conditional on 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 2017 through March 31, 2019, 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 March 31, 2019 and December 31, 2018, respective totals of 1,773,102 and 1,443,897 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 $19 million as of March 31, 2019. 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, in 2015, we had repurchased 2.0 million shares of our common stock for $100 million. We did not repurchase any shares during 2016 through March 31, 2019. We account for the shares we hold in treasury under the cost method, at average cost.

8. INCOME TAXES

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 three-month period ended March 31, 2019, we recognized additional tax expense of $1.4 million from discrete items, primarily related to share-based compensation and valuation allowances. In the three-month period ended March 31, 2018, we recognized additional tax expense of $2.4 million from discrete items, primarily related to a $1.8 million adjustment associated with share-based compensation.

The effective tax rate for the three months ended March 31, 2019 and March 31, 2018 was different than the federal statutory rate of 21.0%, 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. It is our intention to continue to indefinitely reinvest in certain of our international operations; therefore, we do not provide for withholding taxes on the possible distribution of these earnings. We do not believe the effective tax rate before discrete items is meaningful due to the ongoing shifting of geographic mix of our operating revenue and results.

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 expense or benefit for a tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the tax expense or 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 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, penalties and interest, we have accrued a net total of $19 million and $18 million in Other Long-term Liabilities on our balance sheet for unrecognized tax liabilities as of March 31, 2019 and December 31, 2018, respectively. Changes in management's judgment related 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:

In April 2019, negotiations with certain foreign tax authorities related to ongoing tax audits entered the settlement phase. The final settlement has not been completed; however, the expected settlement may have an impact on the uncertain tax position in the three months ended June 30, 2019.

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:


•	second quarter and the full year of 2019 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 2019;


•	future demand and business activity levels;


•	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 to be placed into service in the second quarter of 2019, and other capital expenditures);


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


•	our expectations regarding shares to be repurchased under our share repurchase plan;


•	our assumptions that could affect our estimated tax rate;


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


•	seasonality;


•	industry conditions; and


•	increase in offshore activities and contract awards during the remainder of 2019.

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, 2018. 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, 2018.

Executive Overview

Our diluted earnings (loss) per share for the three months ended March 31, 2019 was $(0.25), as compared to $(0.50) for the corresponding period of the prior year. Our operating results exceeded our expectations and reflected higher than expected activity levels and good execution within our energy-focused businesses.

For the second quarter of 2019, compared to the first quarter, we anticipate quarterly operating profitability improvements in our ROV, Subsea Projects and Advanced Technologies segments and relatively flat quarter-to-quarter results in our Subsea Products and Asset Integrity segments. Unallocated Expenses are expected to be in the mid-$30 million range.

For the full year of 2019, at the segment level, we forecast overall ROV fleet utilization in the upper 50% range and ROV EBITDA margin to remain relatively flat. For Subsea Products, we continue to expect: good order intake during the first half of 2019 driving increased activity in the second half of 2019; a book-to-bill ratio in the range of 1.25 to 1.4 for the full year; and operating margins in the mid-single-digit range. We expect good activity levels in Subsea Projects and Advanced Technologies for the remainder of 2019, with operating margins in the low-double-digit range. For Asset Integrity, we expect a slight increase in activity during the second half of 2019 and operating margins in the low-single-digit range. For the remainder of 2019, we expect our quarterly Unallocated Expenses to average $35 million per quarter.

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


•	increased interest expense, as we will no longer be capitalizing interest on the Ocean Evolution once it is placed into service in the second quarter of 2019, and from higher interest rates, which affect our floating rate debt and our swaps to floating rates on $200 million of fixed-rate debt; and

Table of Contents


•	a loss on our equity investment in Medusa Spar LLC, due to depreciation more than offsetting cash earnings.

We are not providing guidance as to our 2019 annual effective tax rate, due to the ongoing shifting of geographic mix of our operating revenue and results. These conditions do not allow for a meaningful tax rate forecast.

During 2019, we expect each of our operating segments will contribute positive EBITDA and, on a consolidated basis, we will generate sufficient cash flows to service our debt and fund our anticipated maintenance and organic growth capital expenditures.

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, 2018 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, 2019, we adopted Accounting Standards Update 2018-11, an amendment to ASU 2016-02, "Leases" (collectively, the "New Leases Standard"). See Notes 1 and 5 of Notes to Consolidated Financial Statements included in this report for further details, including our accounting policy for the new Leases Standard under this newly adopted accounting standard.

Liquidity and Capital Resources

As of March 31, 2019, we had working capital of $720 million, including $342 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 $30 million during the first three months of 2019 as compared to $26 million in the first three months of 2018, excluding the $68 million purchase price for the Ecosse acquisition. 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 2019, excluding business acquisitions, will be in the range of $105 million to $125 million, including approximately $40 million to $50 million of maintenance capital expenditures and $65 million to $75 million of growth capital expenditures. We expect to place our new-build Jones Act multiservice subsea support vessel Ocean Evolution into service during the second quarter of 2019.

The Ocean Evolution is U.S.-flagged and documented with a coastwise endorsement by the U.S. Coast Guard. The vessel has 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, a working moonpool, and two of our high specification 4,000 meter work-class ROVs. The vessel is also 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 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. This generally minimizes our contract exposure by closely matching our obligations with our revenue. We also charter vessels on a short-term basis as necessary to augment our fleet.

As of March 31, 2019, 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.

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 $19 million and $6 million of cash provided from operating activities in the three-month periods ended March 31, 2019 and 2018, respectively, were principally affected by operating results and cash increases (decreases) of:


•	$22 million and $21 million, respectively, from changes in accounts receivable and contract assets;


•	$(15) million and $(3) million, respectively, from changes in inventory; and


•	$(15) million and $(41) million, respectively, from changes in current liabilities.

The increase in cash related to accounts receivable and contract assets in the first quarter of 2019 was mainly due to various income tax refunds. We had an increase in cash related to accounts receivable in the first quarter of 2018, as we had lower revenue in the first quarter of 2018 as compared to the fourth quarter of 2017. As a result, combined with our cash collections in the first quarter of each of 2019 and 2018, our overall accounts receivable and contract asset balances decreased. The decrease in cash related to inventory as of March 31, 2019 was based on increases in ROV-related inventory due to increased days on hire and Manufactured Products related to an increase in backlog. The decrease in cash related to current liabilities in the first quarter of 2019 was mainly due to

Table of Contents

the payment of foreign jurisdictional income and withholding taxes. The first quarter of 2018 decrease in cash related to current liabilities reflected generally lower business levels.

In the three months ended March 31, 2019, we used $30 million of cash in investing activities related to capital expenditures. We also used $2.3 million in financing activities. In the three months ended March 31, 2018, we used $92 million of cash in investing activities. The cash used in investing activities related to capital expenditures of $26 million and $68 million paid in the Ecosse acquisition. We also used $5.8 million in financing activities, as a result of the repayment of the $300 million term loan facility under the Credit Agreement, substantially offset by the net proceeds from the issuance of the 2028 Senior Notes, net of issuance costs, of $296 million.

We have not guaranteed any debt not reflected on our Consolidated Balance Sheets as of March 31, 2019, 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 March 31, 2019. 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.

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:

Operating Income (Loss)	(21,714		)	(27,149		)	(97,144		)
Operating Income %	(4		)%	(7		)%	(20		)%

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 expenses and the offshore renewable energy market.

Table of Contents

The following table sets forth the Revenue, Gross 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 industry. Since the downturn in oil prices in mid-2014, we have experienced lower activity levels and reduced pricing. In 2019, with oil prices stabilizing and activity in some areas improving, we believe that we are in the early stages of a recovery in activity in general, and in our businesses. We expect that a recovery will take time, and only after a sustained higher level of activity can the prices for our services and products be increased enough to generate satisfactory returns.

Table of Contents

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, and we have experienced lower utilization and pricing in recent years. Our ROV operating income increased in the three months ended March 31, 2019 compared to the corresponding period of the prior year, mainly due to increased days on hire as utilization improved to 53% from 44%. During the first quarter of 2019, ROV operating results increased compared to the immediately preceding quarter due to increased revenue per day-on-hire largely attributable to reimbursement of costs associated with mobilizations and installations, and our fleet utilization improved to 53% from 52%. We added seven new ROVs to our fleet during the three months ended March 31, 2019 and retired seven, resulting in a total of 275 ROVs in our ROV fleet. We expect our second quarter 2019 ROV operating results to improve from the first quarter results, due to a seasonal increase in days on hire. For the full year 2019, we continue to project increased days on hire in both drill support and vessel-based activity. Although we endeavor to maintain and increase our drill support market share and place more ROVs on vessels, we need a sizable increase in our customers' offshore activity and spending levels for there to be a discernible increase in ROV pricing and profitability.

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
	Mar 31, 2019		Mar 31, 2018		Dec 31, 2018
Manufactured products	51	%	59	%	55	%

Service and rental	49	%	41	%	45	%

Our Subsea Products operating results decreased in the three-month period ended March 31, 2019 compared to the corresponding period of the prior year, mainly due to lower throughput in manufactured products. Subsea Products operating results in the first quarter of 2019 was higher than that of the immediately preceding quarter on flat revenue. This improvement was largely due to higher levels of Service and Rental activity at improved margins achieved by good execution, including successfully closing out several projects.

Our Subsea Products backlog was $464 million as of March 31, 2019, compared to $332 million as of December 31, 2018. The backlog increase was largely attributable to increased umbilical and related hardware order intake in our manufactured products business. Our book-to-bill ratio for the trailing twelve months was 1.4. During the quarter, our order intake included two unannounced binding letters associated with significant pending contract awards. This unusual step allowed us to procure long lead time items to meet customers' expected delivery dates. We expect Subsea Products operating results to be flat in the second quarter of 2019 compared to the first quarter. During the second half of 2019, we expect an increase in umbilical and related hardware revenue based on booked work and expected contract awards. Our Subsea Products book-to-bill ratio is expected to be in the range of 1.25 to 1.4 for the full year.

Our Subsea Projects operating results increased in the three-month period ended March 31, 2019 compared to the corresponding period of the prior year, due to increased vessel demand, Gulf of Mexico construction work and increased diving work. Subsea Projects' operating results increased in the first quarter of 2019 compared to the immediately preceding quarter, primarily due to the goodwill impairment charge of $76 million incurred in the fourth quarter of 2018 as a result of the protracted downturn in survey and vessel activity. In the second quarter of 2019, we expect Subsea Projects operating results to improve compared to the first quarter, driven by an increase in demand for our survey services and seasonal increases in vessel and diving work in the U.S. Gulf of Mexico. For the full year of 2019 compared to 2018, we expect Subsea Projects operating results to improve due to increased global demand.

For the three-month period ended March 31, 2019, compared to the corresponding period of the prior year, Asset Integrity's operating results were lower, due to reduced pricing levels. Asset Integrity's operating results in the

Table of Contents

three-month period ended March 31, 2019 compared to the immediately preceding quarter decreased on lower margin work. For the second quarter of 2019, we expect Asset Integrity's revenue and operating results to be relatively flat as compared to the first quarter. For the full year of 2019, we project Asset Integrity operating results to be lower, driven by reduced pricing, and we expect margins to be in the low-single-digit range.

Advanced Technologies

Revenue, Gross Margin and Operating Income information was as follows:



	Three Months Ended
(dollars in thousands)	Mar 31, 2019			Mar 31, 2018			Dec 31, 2018
Revenue	$	114,279		$	85,983		$	116,725

Operating Income	9,599			1,668			15,406
Operating Income %	8		%	2		%	13		%

Advanced Technologies operating income for three-month period ended March 31, 2019 was higher than that of the corresponding period of the prior year, due to an increase in volume primarily related to government-related work, as well as improved execution in our Automated Guided Vehicles ("AGV") business. Operating income in the first quarter of 2019 was lower than that of the immediately preceding quarter, due to a shift in mix, with increased revenue on our lower margin government-related work and reduced revenue on our higher margin work in our entertainment group. We expect an increase in our Advanced Technologies operating income in the second quarter of 2019 compared to the first quarter, as a result of continued increased activity and improved operating margins in both our government and commercial businesses. For the full year of 2019, we continue to anticipate Advanced Technologies operating income to be higher, due to increased activity within our entertainment group supporting the theme park business, improved execution in our AGV business and marginal overall growth in our government businesses.

Our Advanced Technologies segment consists of two business units: (1) government; and (2) commercial. Government services and products include engineering and related manufacturing in defense and space exploration activities. Our commercial business unit offers a turnkey solution that includes program management, engineering design, fabrication/assembly and installation to the commercial theme park industry and mobile robotics solutions including automated guided vehicle technology to a variety of industries. The following table presents revenue from government and commercial, as their respective percentages of total Advanced Technologies revenue:



	Three Months Ended
	Mar 31, 2019		Mar 31, 2018		Dec 31, 2018
Government	71	%	69	%	62	%

Commercial	29	%	31	%	38	%

Unallocated Expenses

Our Unallocated Expenses, (i.e., those not associated with a specific business segment), within gross margin 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 expense consist of those expenses within gross margin plus general and administrative expenses related to corporate functions.

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

Operating Expense	34,434			27,494			29,442
Operating expense % of revenue	7		%	7		%	6		%

Our Unallocated Expenses for the three-month period ended March 31, 2019 increased compared to the corresponding period of the prior year, primarily due to higher 2019 estimated expenses related to incentive compensation from our performance units and bonuses. Our Unallocated Expenses for the three months ended March 31, 2019 were higher compared to the immediately preceding quarter, due to higher estimated incentive plan compensation. For the remainder of 2019, we expect our quarterly Unallocated Expenses to average $35 million per quarter due to the expectation for higher projected short- and long-term performance based incentive compensation expense and global Information Technology expenses.

Other

The following table sets forth our significant financial statement items below the Income (Loss) from Operations line.

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-month periods ended March 31, 2019 and 2018, we incurred foreign currency transaction gains (losses) of $0.6 million and $(8.3) million, respectively. We did not incur any significant currency transaction losses in any one currency in 2019. 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. We could incur further foreign currency exchange losses in Angola if further currency devaluations occur. However, in 2019, we expect lower foreign currency exchange losses, due to lower cash balances in Angolan kwanza.

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 three months ended March 31, 2019 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 other discrete items. 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 due to the ongoing shifting of geographic mix of our operating revenue and results. Our 2019 income tax payments are anticipated to be approximately $25 million, net. The effective tax rate for the three months ended March 31, 2018 was lower than the statutory rate of 21.0%, 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 2018, 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 $6.2 million and $22.2 million in the three-month periods ended March 31, 2019 and 2018, 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 gains (losses) of $0.6 million and $(8.3) million in the three-month periods ended March 31, 2019 and 2018, respectively. Those gains (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, with the exception that 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 less than $0.1 million and $7.7 million in the three-month periods ended March 31, 2019 and 2018, respectively, 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. Any conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola, and the central bank slowed this process from mid-2015 to 2017, causing our kwanza cash balances to increase during that period of time. However, beginning in 2018, the Angolan central bank has allowed us to repatriate cash from Angola. During 2018, we were able to repatriate $74 million of cash from Angola.

As of March 31, 2019 and December 31, 2018, we had the equivalent of approximately $7.7 million and $9.3 million, respectively, of kwanza cash balances in Angola reflected on our Consolidated Balance Sheets.

We estimated the fair market value of the Angolan bonds to be $10 million as of March 31, 2019 and December 31, 2018 using quoted market 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 March 31, 2019 and December 31, 2018, the difference between the fair market value and the carrying amount of the Angolan bonds was immaterial.

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 March 31, 2019 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 March 31, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting, except for the implementation of information technology software, controls and procedures associated with the adoption of the Financial Accounting Standards Board Topic 842, Leases.

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.

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.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Litigation. In the ordinary course of business, we are, from time to time, involved in litigation or subject to disputes, governmental investigations 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, premises liability claims and other claims. 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 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 other dispute resolution proceedings and, in some cases, the availability and amount of potentially available 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. 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 $749 million as of March 31, 2019, 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 $1.5 million as of March 31, 2019, 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, with the exception that 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 less than $0.1 million and $7.7 million in the three-month periods ended March 31, 2019 and 2018, respectively, 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. Any conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola, and the central bank slowed this process from mid-2015 to 2017, causing our kwanza cash balances to increase during that period of time. However, beginning in 2018, the Angolan central bank has allowed us to repatriate cash from Angola. As of March 31, 2019 and December 31, 2018, we had the equivalent of approximately $7.7 million and $9.3 million, respectively, of kwanza cash balances 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. During 2018, we received a total of $70 million proceeds from maturities and redemptions of Angolan bonds and reinvested $10 million of the proceeds in similar assets. As of March 31, 2019 and December 31, 2018, we have $10 million of Angolan bonds on our Consolidated Balance Sheets. Because we intend to sell the bonds if we are able to repatriate the proceeds, we classified these bonds as available-for-sale securities, and they are recorded as Other current assets on our Consolidated Balance Sheets. We estimated the fair market value of the bonds to be $10 million as of March 31, 2019 and December 31, 2018 using quoted prices.

As of March 31, 2019 and December 31, 2018, the difference between the fair market value and the carrying amount of the Angolan bonds was immaterial.

Earnings (Loss) Per Share, Stock-Based Compensation and Share Repurchase Plan	3 Months Ended

Shareholders' Equity, Earnings Per Share And Stock-Based Compensation [Abstract]
Earnings (Loss) per Share, Share-based Compensation and Share Repurchase Plan	EARNINGS (LOSS) PER SHARE, SHARE-BASED COMPENSATION AND SHARE REPURCHASE PLAN Earnings (Loss) 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. Share-Based Compensation. We have no outstanding stock options and, therefore, no share-based compensation to be recognized pursuant to stock option grants. During 2017, 2018 and through March 31, 2019, we granted restricted units of our common stock to certain of our key executives and employees. During 2017, 2018 and 2019, 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 stock we grant to our non-employee directors vest in full on the first anniversary of the award date, conditional on 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 2017 through March 31, 2019, 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 March 31, 2019 and December 31, 2018, respective totals of 1,773,102 and 1,443,897 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 $19 million as of March 31, 2019. 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, in 2015, we had repurchased 2.0 million shares of our common stock for $100 million. We did not repurchase any shares during 2016 through March 31, 2019. We account for the shares we hold in treasury under the cost method, at average cost.
