We ~~perform~~provide contract drilling services with our global fleet of mobile offshore drilling units. As of ~~May 5, 2017,~~March 31, 2018, our fleet consisted of ~~14 jackups,~~ eight drillships, six semisubmersibles and ~~six semisubmersibles.~~14 jackups.

We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our ~~business, and the fact that all of our drilling fleet is dependent upon the worldwide oil and gas industry.~~business. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist ~~largely~~primarily of ~~major~~large, integrated, independent and government-owned or controlled oil and gas companies throughout the world. As of March 31, 2017, our contract drilling services segment conducted operations in the United States, the North Sea, South Africa, the Middle East, Asia and South America. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921.

Noble Corporation, a Cayman Islands company (“Noble-Cayman”), is an indirect, wholly-owned subsidiary of Noble-UK, our publicly-traded parent company. Noble-UK’s principal asset is all of the shares of Noble-Cayman. Noble-Cayman has no public equity outstanding. The condensed consolidated financial statements of Noble-UK include the accounts of Noble-Cayman, and Noble-UK conducts substantially all of its business through Noble-Cayman and its subsidiaries.

The accompanying unaudited condensed consolidated financial statements of Noble-UK and Noble-Cayman have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) as they pertain to Quarterly Reports on Form 10-Q. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the financial position and results of operations for the interim periods, on a basis consistent with the annual audited condensed consolidated financial statements. All such adjustments are of a recurring nature. The December 31, ~~2016~~2017 Condensed Consolidated Balance Sheets presented herein are derived from the December 31, ~~2016~~2017 audited consolidated financial statements. These interim financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, ~~2016,~~2017, filed by both Noble-UK and Noble-Cayman. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.

~~Certain~~We have made certain reclassifications to our prior period amounts in ~~prior periods have been reclassified~~our operating revenue by combining other revenue with reimbursables revenue to conform to the current ~~year~~period presentation. Such reclassification did not have a material effect on our condensed consolidated statements of operations.

We have made certain reclassifications to our prior period amounts in our investing activities by combining changes in accrued capital expenditures with capital expenditures to conform to the current period presentation. Such reclassification did not have a material effect on our condensed consolidated statements of cash flows.

Note 2— Accounting Pronouncements

Accounting Standards Adopted

In ~~accordance with our adoption of~~May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. ~~2016-09, excess tax benefits of approximately $5.5 million as of March 31, 2016, previously classified as a financing activity~~2014-9, which creates Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers,” and supersedes the revenue recognition requirements in ~~“Employee stock transactions,~~Topic 605, “Revenue Recognition,” ~~are classified as an operating activity in “Other current liabilities” on~~including most industry-specific revenue recognition guidance throughout the accompanying Consolidated Statement of Cash Flows. Shares withheld for taxes on employee stock transactions of approximately $3 million as of March 31, 2016, previously classified as an operating activity in “Other current liabilities,” are classified as a financing activity in “Employee stock transactions” in the accompanying Consolidated Statement of Cash Flows.

~~Note 2 — Spin-off of Paragon Offshore plc (“Paragon Offshore”)~~

~~On August 1, 2014, Noble-UK completed the separation and spin-off of a majority of its standard specification offshore drilling business (the “Spin-off”) through a pro rata distribution of all~~Industry Topics of the ~~ordinary shares~~Codification. In addition, ASU No. 2014-9 supersedes the cost guidance in Subtopic 605-35, “Revenue Recognition—Construction-Type and Production-Type Contracts,” and creates new Subtopic 340-40, “Other Assets and Deferred Costs—Contracts with Customers.” Under the new guidance, revenue is recognized when a customer obtains control of ~~its wholly-owned subsidiary, Paragon Offshore,~~promised goods or services and in an amount that reflects the consideration the entity expects to ~~the holders of Noble’s ordinary shares.~~

In February 2016, Paragon Offshore sought approval of a pre-negotiated plan of reorganization (the "Prior Plan") by filing for voluntary relief under Chapter 11 of the United States Bankruptcy Code. As part of the Prior Plan, we entered into a settlement agreement with Paragon Offshore (the “Settlement Agreement”) under which,receive in exchange for ~~a full~~those goods or services.

We adopted ASU 2014-09 and ~~unconditional release~~its related amendments, or collectively Topic 606, effective January 1, 2018 using the modified retrospective implementation method. Accordingly, we have applied the five-step method outlined in Topic 606 for determining when and how revenue is recognized to all contracts that were not completed as of ~~any claims by Paragon Offshore in connection with~~ the ~~Spin-off (including fraudulent conveyance claims that could be brought on behalf~~date of ~~Paragon Offshore’s creditors), we agreed to provide certain tax bonding in Mexico as well as assume certain tax liabilities~~adoption. Revenues for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts have not been adjusted and ~~the administration of Mexican tax claims for a specified number of years.~~ ~~The bonding~~continue to be ~~provided by Noble-UK was a key benefit~~reported under the previous revenue recognition guidance. For contracts that were modified before the effective date, we have considered the modification guidance within the new standard and determined that the revenue recognized and contract balances recorded prior to ~~Paragon Offshore~~adoption for such contracts were not impacted. While Topic 606 requires additional disclosure of the ~~Settlement Agreement,~~nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, its adoption has not had a material impact on the measurement or recognition of our revenues. Our adoption, using the modified retrospective approach, for which ~~was subject~~we were not required to ~~bankruptcy court confirmation as part of a bankruptcy plan. The Prior Plan was rejected by the bankruptcy court in October 2016.~~

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data)

~~abandoned~~In October 2016, the ~~Settlement Agreement as part~~FASB issued ASU No. 2016-16, which amends ASC Topic 740, “Income Taxes.” The amendments in this update improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This standard is effective for interim and annual reporting periods beginning after December 15, 2017. We have adopted the new standard effective January 1, 2018 under the modified retrospective approach. As a result of the ~~New Plan~~modified retrospective application, “Other Assets” is reduced in our Condensed Consolidated Balance Sheet with a cumulative adjustment to retained earnings of approximately $149.9 million as of March 31, 2018.

In February 2018, the FASB issued ASU No. 2018-2, which amends ASC Topic 220, “Income Statement—Reporting Comprehensive Income.” The amendments in this update allow for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Act”). This standard is effective for interim and annual reporting periods beginning after December 15, 2018 with early application permitted. We have elected to adopt the new standard effective January 1, 2018 under the modified retrospective approach. The amendment should be applied on a retrospective basis to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act was recognized. As a result of the retrospective application, we will reduce “Accumulated Other Comprehensive Income” with a cumulative adjustment to “Retained Earnings” of approximately $5.5 million as of March 31, 2018.

In March 2017, the FASB issued ASU No. 2017-7, which amends ASC Topic 715, “Compensation —Retirement Benefits; Improving the Presentation of Net Periodic Pension Cost and Postretirement Benefits Cost.” The amendments in this update require that an employer disaggregate the service cost component from the other components of net benefit cost for an entity's defined benefit pension and other postretirement plans. The amendments also provide explicit guidance on how to present the service cost component and the ~~Settlement Agreement was terminated at the time~~other components of the filing of the New Plan. On May 2, 2017, Paragon Offshore announced that it had reached an agreement in principle with both its secured and unsecured creditors to revise the New Plan to, among other things, create and fund a litigation trust to pursue litigation against us.

~~We continue to discuss our continuing relationship with Paragon Offshore, including the possibility of entering into a new settlement agreement.~~ There can be no assurance that the Company will reach any such settlement agreement with Paragon Offshore. If we do not enter into a settlement agreement with Paragon Offshore, we expect Paragon Offshore or its creditors would use the litigation trust to pursue claims against us relating to the Spin-off, including any alleged fraudulent conveyance claims. We continue to believe that Paragon Offshore, at the time of the Spin-off, was properly funded, solvent and had appropriate liquidity and that any fraudulent conveyance claim or other claim related to the Spin-off that may be brought by Paragon Offshore or its creditors, would be without merit and would be contested vigorously by us (see Note 14 for additional information).

~~Master Separation Agreement (“MSA”)~~

~~The general terms and conditions relating to the separation and Spin-off are set forth~~net benefit cost in the ~~MSA.~~income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. The ~~MSA identifies~~amendments in this update require that an employer report the ~~assets transferred, liabilities assumed and contracts assigned either to Paragon Offshore by us or by Paragon Offshore to us~~service cost component in the ~~separation~~same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit costs, as defined in paragraphs 715-30-35-4 and ~~describes when~~715-60-35-9, are required to be presented in the income statement separately from the service cost component and ~~how these transfers, assumptions~~outside of income from operations. We adopted ASU No. 2017-7 effective January 1, 2018 and assignments would occur. The MSA provides for, among other things, Paragon Offshore’s responsibility for liabilities relating to its business and the responsibility of Noble-UK for liabilities relatedaccordingly, we have made certain reclassifications to our prior period amounts between “Contract drilling services” costs and in certain limited cases, Paragon Offshore’s business, in each case irrespective of when the liability arose. The MSA also contains indemnification obligations and ongoing commitments by us and Paragon Offshore.

~~Employee Matters Agreement (“EMA”)~~

~~The EMA allocates liabilities and responsibilities between us and Paragon Offshore relating to employment, compensation and benefits~~“Interest income and other, ~~employment related matters.~~

~~Tax Sharing Agreement (“TSA”)~~

~~The TSA provides for the allocation of tax liabilities and benefits between us and Paragon Offshore and governs the parties’ assistance with tax-related claims.~~

~~Transition Services Agreements~~

Under two transition services agreements, we agreed to continue, for a limited period of time, to provide various interim support services to Paragon Offshore, and Paragon Offshore agreed to provide various interim support services to us, including providing operational and administrative support for our remaining Brazilian operations.

In the course of its bankruptcy, Paragon Offshore may elect to reject the Separation Agreements. If Paragon Offshore rejects the Separation Agreements, the indemnity obligations that Paragon Offshore may owe us under the Separation Agreements would terminate, including indemnities arising under the MSA and the TSA in respect of obligations related to Paragon Offshore’s business that were incurred through Noble-retained entities prior to the Spin-off. We could, however, pursue claims against Paragon Offshore for such indemnity amounts in the bankruptcy proceeding. Any such claims would be unsecured claims in the bankruptcy. Likewise, any indemnity obligations that we may owe Paragon Offshore under the Separation Agreements, including those under the MSA and the TSA in respect of Noble-UK’s business that was conducted prior to the Spin-off through Paragon Offshore-retained entities, would also be extinguished. We donet.” Such reclassifications did not ~~expect that a rejection of the Separation Agreements by Paragon Offshore would~~ have a material ~~adverse~~ effect on our condensed consolidated statement of operations.

Issued Accounting Standards

In February 2016, the FASB issued ASU No. 2016-2, which creates ASC Topic 842, “Leases.” This update increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This standard is effective for interim and annual reporting periods beginning after December 15, 2018. Our adoption, and the ultimate effect on our consolidated financial statements, will be based on an evaluation of the contract-specific facts and circumstances. We expect to adopt ASC 842 effective January 1, 2019. We expect to apply the modified retrospective approach to our adoption. Our adoption will have an impact on how our consolidated financial statements and related disclosures will be presented. With respect to leases whereby we are the lessee, we are currently expecting to recognize lease liabilities and offsetting “right of use” assets upon adoption. We are currently evaluating any other impacts of ASC 842, including any newly issued guidance, will have on our condensed consolidated financial statements and related disclosures. To facilitate that evaluation, we have completed training on the ASU, formed an implementation team and started the review and documentation of contracts.

In February 2017, the FASB issued ASU No. 2017-6, which amends ASC Topic 960, “Defined Benefit Pension Plans,” ASC Topic 962, “Defined Contribution Pension Plans” and ASC Topic 965, “Health and Welfare Benefit Plans.” The amendments in this update clarify presentation requirements for an employee benefit plan’s interest in a master trust and require more detailed disclosures of the plan’s interest in the master trust. The amendments also eliminate a redundancy relating to 401(h) account disclosures. This standard is effective for fiscal years beginning after December 15, 2018, with early application permitted. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, ~~or liquidity. However, any loss we experience with respect to which we are unable to secure indemnification from Paragon Offshore could have an adverse impact on our~~ results of operations, ~~in any period, which impact may be material depending on~~cash flows or financial disclosures.

With the exception of the updated standards discussed above, there have been no new accounting pronouncements not yet effective that have significance, or potential significance, to our ~~results of operations during this down-cycle.~~condensed consolidated financial statements.

Note ~~3 —~~3— Consolidated Joint Ventures

We maintain a 50 percent interest in two joint ventures, each with a subsidiary of Royal Dutch Shell plc (“Shell”), that own and operate the two Bully-class drillships. We have determined that we are the primary beneficiary of the joint ventures. Accordingly, we consolidate the entities in our condensed consolidated financial statements after eliminating intercompany transactions. Shell’s equity interests are presented as noncontrolling interests on our Condensed Consolidated Balance Sheets.

During the three months ended March 31, 2017 and 2016, the Bully joint ventures approved and paid dividends totaling $11 million and $43 million, respectively. Of these amounts, 50 percent was paid to our joint venture partner.

The declaration and payment of dividends require authorization of the Board of Directors of Noble-UK, provided that such dividends on issued share capital may be paid only out of Noble-UK’s “distributable reserves” on its statutory balance sheet. Noble-UK is not permitted to pay dividends out of share capital, which includes share premiums.

Share repurchases

Under UK law, the Company is only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by shareholders. ~~Prior to April 22, 2016, we had shareholder approval to repurchase up to 37 million ordinary shares.

Pursuant to the FCX Settlement, Noble may receive payments based upon the average price of oil over a 12 month period from June 30, 2016 through June 30, 2017. These contingent payments were not designated for hedge accounting treatment under FASB standards, and therefore, changes in fair value are recognized as either income or loss in the accompanying Consolidated Statements of Operations. For the three months ended March 31, 2017, we recognized a loss of approximately $7.9 million in “Contract drilling services revenue,” related to the valuation of this contingent payment. As of March 31, 2017, the estimated fair value of these contingent payments was $6.5 million which is included in “Prepaid expenses and other current assets” (see Note 11 for additional information).

~~Note 6 —~~5— Receivables from Customers

At ~~March~~December 31, ~~2017,~~2016, we had receivables of approximately ~~$14~~$14.4 million related to the Noble Max Smith, which ~~are being~~had been disputed by our former customer, Petróleos Mexicanos (“Pemex”)~~.

As of December 31, 2017, Paragon Offshore announced that, as part of its bankruptcy plan, it will liquidate the Mexican entity involved.

While Noble owns all rights to amounts from that claim and will take available actions to recover such amounts, we ~~filed a lawsuit against Pemex in Mexican court seeking recovery of these amounts. While we can make no assurances as~~believe the announced actions by Paragon Offshore create uncertainty relating to the ~~outcome~~prosecution of ~~this dispute, we believe we are entitled to~~the claim and associated recovery, and accordingly, the disputed ~~amounts.~~amounts of approximately $14.4 million were written off through “Contract drilling services” costs during the year ended December 31, 2017.

Credit Facilities

2015 Credit Facility

At December 31, 2017, we had a five-year $2.4 billion senior unsecured credit facility that matures in January 2020 and is guaranteed by our indirect, wholly-owned subsidiaries, Noble Holding (U.S.) LLC (“NHUS”) and Noble Holding International Limited (“NHIL”) (the “2015 Credit Facility”). At December 31, 2017, the 2015 Credit Facility also provided us with the ability to issue up to $500.0 million in letters of credit.

On December 19, 2017, we entered into the First Amendment and Consent and Successor Agent Agreement (the “Amendment”) amending the 2015 Credit Facility. On January 3, 2018, the Amendment to the 2015 Credit Facility became fully effective. The Amendment caused, among other things, a reduction in the aggregate principal amount of commitments under the 2015 Credit Facility to $300.0 million and ~~$51 million for~~ the ~~three months ended~~termination of the 2015 Credit Facility's letter of credit sub-facility. The maturity of the 2015 Credit Facility remains January 2020. As a result of the 2015 Credit Facility's reduction in the aggregate principal amount of commitments, we recognized a net loss of approximately $2.3 million. At March 31, 2018, we had no borrowings outstanding under the 2015 Credit Facility.

The maximum aggregate amount of commitments under the 2017 Credit Facility of approximately $1.5 billion became available in January 2018 upon satisfaction of certain conditions, including the effectiveness of the commitment reduction under the 2015 Credit Facility. Borrowings under the 2017 Credit Facility are subject to certain conditions precedent, including that there be no ~~capitalized interest~~unused commitments to advance loans under the 2015 Credit Facility. The 2017 Credit Facility provides for a letter of credit sub-facility currently in the ~~three months ended~~amount of $15.0 million, with the ability to increase such amount up to $500.0 million. Borrowings may be used for working capital and other general corporate purposes. The 2017 Credit Facility will mature in January 2023.

~~Credit~~ Facility ~~and Commercial Paper Program~~

We currently have a five-year $2.4 billion senior unsecured credit facility that matures in January 2020 and is guaranteed by our indirect, wholly owned subsidiaries, Noble Holding (U.S.) LLC ("NHUS") and Noble Holding International Limited ("NHIL"). The credit facility provides us with the ability to issue up to $500 million in letters of credit. The issuance of letters of credit under the facility reduces the amount available for borrowing.

~~Throughout the term of the credit facility, we pay a facility fee~~ on the daily unused amount of the underlying ~~commitment~~commitments, in each case which ~~ranges from 0.1 percent to 0.35 percent~~varies depending on our ~~debt~~credit ratings. At March 31, ~~2017, based on our debt ratings on that date,~~2018, the ~~facility fee was 0.35 percent. At March 31, 2017, we had no borrowings outstanding or letters of credit issued. In addition, our credit facility has provisions which vary the applicable~~ interest rates ~~based upon our debt ratings. At March 31, 2017, the interest rate~~ in effect isunder our Credit Facilities are the highest permitted interest ~~rate~~rates under ~~the credit facility.~~

During 2016, we terminated our commercial paper program which had allowed us to issue up to $2.4 billion in unsecured commercial paper notes. This termination does not reduce the capacity under our credit facility.those agreements.

Debt Issuances

In ~~December 2016,~~January 2018, we issued ~~$1 billion~~$750.0 million aggregate principal amount of ~~7.75%~~our Senior Notes ~~which we issued~~due 2026 (the “2026 Notes”) through our indirect wholly-owned subsidiary, NHIL. The net proceeds of the offering of approximately ~~$968~~$737.4 million, after estimated expenses, were ~~primarily~~ used to retire ~~debt~~a portion of our near-term senior notes in a related tender offer.

The 2026 Notes are redeemable, in whole or in part, prior to ~~our tender offer~~February 1, 2021, at a redemption price equal to 100% of the aggregate principal amount of the 2026 Notes being redeemed, plus a make-whole premium. Prior to February 1, 2021, we may also redeem up to 40% of the 2026 Notes in an amount not to exceed the net cash proceeds of certain equity offerings at a redemption price equal to approximately 108% of their aggregate principal amount. Further, the 2026 Notes may be redeemed in whole at par as a result of changes in tax law requiring us to withhold taxes from payments on the 2026 Notes. On or after February 1, 2021, we may redeem all or any portion of the 2026 Notes at various redemption prices set forth in the indenture.

Upon (i) the occurrence of a change of control and (ii) a downgrade of the ~~remaining portion~~rating of the 2026 Notes within 60 days after the change of control by at least two of Moody’s Investors Service, Inc., Standard & Poor’s Financial Services LLC or Fitch Ratings Inc. we will be ~~used~~required to make an offer to repurchase all outstanding 2026 Notes at a price in cash equal to 101% of the aggregate principal amount of the 2026 Notes repurchased, plus any accrued and unpaid interest to, but excluding, the repurchase date.

The indenture for ~~general corporate purposes.~~the 2026 Notes contains certain covenants and restrictions, including, among others, restrictions on our and our subsidiaries’ ability, as applicable, to create certain liens, enter into certain sale and leaseback transactions, merge or consolidate with another entity, sell all or substantially all of their assets and allow our subsidiaries to incur certain additional indebtedness. Additionally, the Subsidiary Guarantors must own, directly or indirectly, (i) assets comprising at least 85% of the revenue of Noble-Cayman and its subsidiaries on a consolidated basis and (ii) jackups, semisubmersibles, drillships, submersibles or other mobile offshore drilling units of material importance, the combined book value of which comprises at least 85% of the combined book value of all such assets of Noble-Cayman and its subsidiaries on a consolidated basis, in each case, with respect to the most recently completed fiscal year.

Senior Notes Interest Rate Adjustments

During 2016 and 2017, we experienced ~~several~~ debt rating downgrades by Moody’s Investors Service and S&P Global Ratings, which reduced our debt ratings significantly below investment grade. As a result of these downgrades, we experienced interest rate increases during 2016 and 2017 on our Senior Notes due 2018 (the “2018 Notes”), our Senior Notes due 2025 (the “2025 Notes”) and our Senior Notes due 2045 (the “ 2045 Notes”), all of which are subject to provisions ~~which~~that vary the applicable interest rates ifbased on our debt rating. On October 18, 2017, S&P Global Ratings further reduced our debt rating, ~~falls below investment grade, with continued adjustments up~~which increased the interest rates on the 2025 Notes and the 2045 Notes to ~~a contractually-defined~~7.95% and 8.95%, respectively, in April 2018. These senior notes have reached the contractually defined maximum interest rate ~~increase~~ set for each rating ~~agency. Effective March 2017, the interest rates on our Senior Notes due 2018 increased to 5.75%~~agency and effective April 1, 2017, the interest rates on our Senior Notes due 2025 and 2045 increased to 7.70% and 8.70%, respectively, as a result of the most recent debt rating downgrade.

Fair Value of Debt

Fair value represents the amount at which an instrument could be exchanged in a current transaction between willing parties. The estimated fair value of our senior notes was based on the quoted market prices for similar issues or on the current rates offered to us for debt of similar remaining maturities (Level 2 measurement). All remaining fair value disclosures are presented in ~~Note 12.~~“Note 13— Fair Value of Financial Instruments.”

Note 9— Revenue and Customers

Overview

The activities that primarily drive the revenue earned in our drilling contracts include (i) providing a drilling rig and the crew and supplies necessary to operate the rig, (ii) mobilizing and demobilizing the rig to and from the drill site, and (iii) performing rig preparation activities and/or modifications required for the contract. Consideration received for performing these activities may consist of dayrate drilling revenue, mobilization and demobilization revenue, contract preparation revenue and reimbursement revenue. We account for these integrated services provided within our drilling contracts as a single performance obligation satisfied over time and comprised of a series of distinct time increments in which we provide drilling services.

Our standard drilling contracts require that we operate the rig at the direction of the customer throughout the contract term (which is the period we estimate to be benefited from the corresponding activities and generally ranges from two to 60 months). The activities performed and the level of service provided can vary hour to hour. Our obligation under a standard contract is to provide whatever level of service is required by the operator, or customer, over the term of the contract. We are, therefore, under a stand-ready obligation throughout the entire contract duration. Consideration for our stand-ready obligation corresponds to distinct time increments, though the rate may be variable depending on various factors, and is recognized in the period in which the services are performed. The total transaction price is determined for each individual contract by estimating both fixed and variable consideration expected to be earned over the term of the contract. We have elected to exclude from the transaction price measurement all taxes assessed by a governmental authority. See further discussion regarding the allocation of the transaction price to the remaining performance obligations below.

The amount estimated for variable consideration may be subject to interrupted or restricted rates and is only included in the transaction price to the extent that it is probable that a significant reversal of previously recognized revenue will not occur throughout the term of the contract ("constrained revenue"). When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue as well as the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required.

Dayrate Drilling Revenue. Our drilling contracts generally provide for payment on a dayrate basis, with higher rates for periods when the drilling unit is operating and lower rates or zero rates for periods when drilling operations are interrupted or restricted. The dayrate invoices billed to the customer are typically determined based on the varying rates applicable to the specific activities performed on an hourly basis. Such dayrate consideration is allocated to the distinct hourly increment it relates to within the contract term, and therefore, recognized in line with the contractual rate billed for the services provided for any given hour.

Mobilization/Demobilization Revenue. We may receive fees (on either a fixed lump-sum or variable dayrate basis) for the mobilization and demobilization of our rigs. These activities are not considered to be distinct within the context of the contract and, therefore, the associated revenue is allocated to the overall performance obligation and recognized ratably over the initial term of the related drilling contract. We record a contract liability for mobilization fees received, which is amortized ratably to contract drilling revenue as services are rendered over the initial term of the related drilling contract.

In most contracts, there is uncertainty as to the amount of expected demobilization revenue due to contractual provisions that stipulate that certain conditions must be present at contract completion for such revenue to be received and as to the amount thereof, if any. For example, contractual provisions may require that a rig demobilize a certain distance before the demobilization revenue is payable or the amount may vary dependent upon whether or not the rig has additional contracted work within a certain distance from the wellsite. Therefore, the estimate for such revenue may be constrained, as described earlier, depending on the facts and circumstances pertaining to the specific contract. We assess the likelihood of receiving such revenue based on past experience and knowledge of the market conditions. In cases where demobilization revenue is expected to be received upon contract completion, it is estimated as part of the overall transaction price at contract inception and recognized in earnings ratably over the initial term of the contract with an offset to an accretive contract asset.

Contract Preparation Revenue. Some of our drilling contracts require downtime before the start of the contract to prepare the rig to meet customer requirements. At times, we may be compensated by the customer for such work (on either a fixed lump-sum or variable dayrate basis). These activities are not considered to be distinct within the context of the contract and, therefore, the related revenue is allocated to the overall performance obligation and recognized ratably over the initial term of the related drilling contract. We record a contract liability for contract preparation fees received, which is amortized ratably to contract drilling revenue over the initial term of the related drilling contract.

Bonuses, Penalties and Other Variable Consideration. We may receive bonus increases to revenue or penalty decreases to revenue. Based on historical data, and ongoing communication with the operator/customer, we are able to reasonably estimate this variable consideration. We will record such estimated variable consideration and re-measure our estimates at each reporting date. For revenue estimated, but not received, we will record to “Prepaid expenses and other current assets” on our Condensed Consolidated Balance Sheets.

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data)

Capital Modification Revenue. From time to time, we may receive fees from our customers for capital improvements to our rigs to meet contractual requirements (on either a fixed lump-sum or variable dayrate basis). Such revenue is allocated to the overall performance obligation and recognized ratably over the initial term of the related drilling contract as these activities are integral to our drilling activities and are not considered to be a stand-alone service provided to the customer within the context of our contracts. We record a contract liability for such fees and recognize them ratably as contract drilling revenue over the initial term of the related drilling contract.

Revenues Related to Reimbursable Expenses. We generally receive reimbursements from our customers for the purchase of supplies, equipment, personnel services and other services provided at their request in accordance with a drilling contract or other agreement. Such reimbursable revenue is variable and subject to uncertainty, as the amounts received and timing thereof is highly dependent on factors outside of our influence. Accordingly, reimbursable revenue is constrained revenue and not included in the total transaction price until the uncertainty is resolved, which typically occurs when the related costs are incurred on behalf of a customer. We are generally considered a principal in such transactions and record the associated revenue at the gross amount billed to the customer as “Revenues related to reimbursable expenses” in our Condensed Consolidated Statements of Operations. Such amounts are recognized ratably over the period within the contract term, during which the corresponding goods and services are to be consumed.

Contract Balances

Accounts receivable are recognized when the right to consideration becomes unconditional based upon contractual billing schedules. Payment terms on invoiced amounts are typically 30 days. Current contract asset and liability balances are included in “prepaid expenses and other current assets” and “other current liabilities,” respectively and noncurrent contract assets and liabilities are included in “other assets” and “other liabilities,” respectively, on our condensed consolidated balance sheets.

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



	March 31, 2018			January 1, 2018
Current contract assets	$	24,330		$	21,229

We have elected, as a practical expedient, not to disclose significant changes in the remaining performance obligation for the three months ended March 31, 2017, which was before our adoption date of January 1, 2018.

Contract Costs

Certain direct and incremental costs incurred for upfront preparation, initial mobilization and modifications of contracted rigs represent costs of fulfilling a contract as they relate directly to a contract, enhance resources of the Company that will be used in satisfying its performance

obligations in the future and are expected to be recovered. Such costs are deferred and amortized ratably to contract drilling expense as services are rendered over the initial term of the related drilling contract.

Costs incurred for the demobilization of rigs at contract completion are recognized as incurred during the demobilization process. Costs incurred for rig modifications or upgrades required for a contract, which are considered to be capital improvements, are capitalized as drilling and other property and equipment and depreciated over the estimated useful life of the improvement.

Transaction Price Allocated to the Remaining Performance Obligations

The following table reflects revenue expected to be recognized in the future related to unsatisfied performance obligations, by rig type, at the end of the reporting period:



	Three Months Ended March 31, 2018

Total ⁽¹⁾	$	27,204	$	26,921	$	18,811	$	15,141	$	12,552	$	100,629

⁽¹⁾ Our Semisubmersible fleet contained no unsatisfied performance obligations as of March 31, ~~2017~~2018.

The revenue included above consists of expected mobilization, demobilization, and ~~December~~upgrade revenue for unsatisfied performance obligations. The amounts are derived from the specific terms within drilling contracts that contain such provisions, and the expected timing for recognition of such revenue is based on the estimated start date and duration of each respective contract based on information known at March 31, ~~2016, respectively:~~2018. The actual timing of recognition of such amounts may vary due to factors outside of our control. We have taken the optional exemption, permitted by accounting standards, to exclude disclosure of the estimated transaction price related to the variable portion of unsatisfied performance obligations at the end of the reporting period, as our transaction price is based on a single performance obligation consisting of a series of distinct hourly, or more frequent, periods, the variability of which will be resolved at the time of the future services.

Our revenue recognition pattern under ASC 606 is materially equivalent to revenue recognition under the previous guidance. For the three months ended March 31, 2018, there were no material effects to our Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Operations, or Condensed Consolidated Statements of Cash Flows.

Note ~~9 —~~10— Income Taxes

At March 31, 2018, the reserves for uncertain tax positions totaled $183.5 million (net of related tax benefits of $1.0 million). At December 31, 2017, the reserves for uncertain tax positions totaled ~~$185~~$191.9 million (net of related tax benefits of $1 million). If the March 31, 2017 reserves are not realized, the provision for income taxes would be reduced by $185 million. At December 31, 2016, the reserves for uncertain tax positions totaled $173 million (net of related tax benefits of $1$1.0 million).

It is reasonably possible that our existing liabilities related to our reserve for uncertain tax positions may fluctuate in the next 12 months primarily due to the completion of open audits or the expiration of statutes of limitation. However, we cannot reasonably estimate a range of changes in our existing liabilities due to various uncertainties, such as the unresolved nature of various audits.

At March 31, 2017, our income tax provision included a non-cash, discrete item of ~~$260~~$260.7 million as the result of an internal tax restructuring, which was implemented to reduce costs associated with the ownership of multiple legal entities, simplify the overall legal entity structure, ease

For interim and annual reporting periods beginning after December 15, 2017, ASU No. 2016-16 will be applied on a modified retrospective basis to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. As the result of the application of this standard, we reclassified deferred charges of $149.9 million in “Other assets” and “Other liabilities” to “Retained earnings” on the accompanying Condensed Consolidated Balance Sheets.

We are accounting for these contingent payments as derivative instruments that do not qualify under the Financial Accounting Standards Board (“FASB”) standards for hedge accounting treatment, and therefore, changes in fair values are recognized as either income or loss in the accompanying Consolidated Statements of Operations.

For foreign currency forward contracts, hedge effectiveness is evaluated at inception based on the matching of critical terms between derivative contracts and the hedged item. Any change in fair value resulting from ineffectiveness is recognized immediately in earnings.

On May 10, 2016, Freeport-McMoRan Inc. (“Freeport”), Freeport-McMoRan Oil & Gas LLC and one of our subsidiaries entered into an agreement terminating the contracts on the Noble Sam Croft and the Noble Tom Madden (“FCX Settlement”), which were scheduled to end in July 2017 and November 2017, respectively. The FCX Settlement included two contingent payments, which are further discussed below. We accounted for these contingent payments as derivative instruments that did not qualify under the FASB standards for hedge accounting treatment, and therefore, changes in fair values were recognized as a loss in the accompanying Condensed Consolidated Statements of Operations.

Cash Flow Hedges

Several of our regional shorebases, including our North Sea operations, have a significant amount of their cash operating expenses payable in local currencies. To limit the potential risk of currency fluctuations, we periodically enter into forward contracts, which ~~settle~~have historically settled monthly in the operations’ respective local currencies. ~~All of these~~These contracts ~~have~~had a maturity of less than 12 months. ~~The forward contract settlements in the remainder of 2017 represent approximately 70 percent of these forecasted local~~There were no foreign currency ~~requirements. The notional amount of the~~ forward contracts entered into or outstanding ~~expressed in U.S. Dollars, was approximately $25 million at March 31, 2017. Total unrealized losses related to these forward contracts were approximately $0.1 million~~ as of March 31, ~~2017 and were recorded as part of “Accumulated other comprehensive loss” (“AOCL”).~~2018.

FCX Settlement

~~As discussed in Note 5, pursuant~~Pursuant to the FCX Settlement, Noble ~~may receive~~could have received contingent payments from the FCX Settlement on September 30, 2017, depending on the average price of oil over a ~~12 month~~12-month period from June 30, 2016 through June 30, 2017. The average price of oil ~~will be~~was calculated using the daily closing price of West Texas Intermediate crude oil (“WTI”) (CL1) on the New York Mercantile Exchange for the period of June 30, 2016 through June 30, 2017. If the price of WTI ~~averages~~averaged more than $50 per barrel during such period, Freeport ~~will pay $25~~would have paid $25.0 million to Noble. In addition to the ~~$25~~$25.0 million contingent payment, if the price of WTI ~~averages~~averaged more than $65 per barrel during such period, Freeport ~~will pay~~would have paid an additional ~~$50~~$50.0 million to Noble. These contingent payments dodid not qualify for hedge accounting treatment under FASB standards, and therefore, ~~changes~~the change in fair ~~values are~~value was recognized as ~~either income or~~a loss in ~~the accompanying~~our Consolidated Statements of Operations. These contingent payments are referred to as non-designated derivatives in the following tables.

For the three months ended March 31, 2017, we recognized a loss of approximately $7.9 million in “Contract drilling services revenue,” related to the valuation of this contingent payment. As of March 31, 2017, the estimated fair value of these contingent payments was $6.5 million which is included in “Prepaid expenses and other current assets.”

Note ~~12 —~~13— Fair Value of Financial Instruments

The FASB guidance establishes a fair value hierarchy that distinguishes between assumptions based on market data from independent sources (“observable inputs”) and a reporting entity’s internal assumptions based upon the best information available when external market data is limited or unavailable (“unobservable inputs”). The fair value hierarchy under FASB guidance prioritizes inputs within three levels:

~~Level 1: Valuations based on quoted prices in active markets for identical assets;~~

Level 2: Valuations based on observable inputs that do not meet the criteria for Level 1, including quoted prices in inactive markets and quoted prices in active markets for similar but not identical instruments; and

~~Level 3: Valuations based on unobservable inputs.~~

Transocean Ltd.

In January 2017, a subsidiary of Transocean Ltd. (“Transocean”) filed suit against us and certain of our subsidiaries for patent infringement in a Texas federal court. The suit claims that five of our newbuild rigs that operated in the U.S. Gulf of Mexico violated Transocean patents relating to what is generally referred to as dual-activity drilling. We were aware of the patents when we constructed the rigs, and we do not believe that our rigs infringe the Transocean patents, which are now expired. The lawsuit is proceeding and we intend to defend ourselves vigorously against this claim.

~~rigs, and we do not believe that our rigs infringe the Transocean patents, which are now expired. We intend to defend ourselves vigorously against this claim.~~Department of Justice settlement.

In December 2014, one of our subsidiaries reached a settlement with the U.S. Department of Justice (“DOJ”) regarding our former drillship, the Noble Discoverer, and the Kulluk, a rig we were providing contract labor services for, in respect of violations of applicable law discovered in connection with a 2012 Coast Guard inspection in Alaska and our own subsequent internal investigation. Under the terms of the agreement, the subsidiary ~~pled guilty to oil record book, ballast record and required hazardous condition reporting violations with respect to the~~ ~~Noble Discoverer~~ ~~and an oil record book violation with respect to the~~ ~~Kulluk.

We also implemented a comprehensive environmental compliance plan in connection with the settlement.

Brazil commercial agent.

We have used a commercial agent in Brazil in connection with our Petróleo Brasileiro S.A. (“Petrobras”) drilling contracts. We understand that this agent has represented a number of different companies in Brazil over many years, including several offshore drilling contractors. In November 2015, this agent pled guilty in Brazil in connection with the award of a drilling contract to a competitor and implicated a Petrobras official as part of a wider investigation of Petrobras’ business practices. Following news reports relating to the agent’s involvement in the Brazil investigation in connection with his activities with other companies, we conducted a review, which is now substantially complete, of our relationship with the agent and with Petrobras. We ~~are~~have been in contact with the SEC, the Brazilian federal prosecutor’s office and the DOJ about this matter. We ~~are cooperating~~have cooperated with these agencies and they are aware of our internal review. To our knowledge, neither the agent, nor the government authorities investigating the matter, has alleged that the agent or Noble acted improperly in connection with our contracts with Petrobras.

We are from time to time a party to various lawsuits that are incidental to our operations in which the claimants seek an unspecified amount of monetary damages for personal injury, including injuries purportedly resulting from exposure to asbestos on drilling rigs and associated facilities. At March 31, 2017, there were 43 asbestos related lawsuits in which we are one of many defendants. These lawsuits have been filed in the United States in the states of Louisiana and Mississippi. We intend to vigorously defend against the litigation. We do not believe the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows.

We are a defendant in certain claims and litigation arising out of operations in the ordinary course of business, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations or cash flows. There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims.

We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We recognize uncertain tax positions that we believe have a greater than 50 percent likelihood of being sustained. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments.

During 2014, the IRS began its examination of our tax reporting in the U.S. for the taxable years ended December 31, 2010 and 2011. The IRS examination team has completed its examination of our 2010 and 2011 U.S. tax returns and proposed adjustments and deficiencies with respect to certain items that were reported by us for the 2010 and 2011 tax year. On December 19, 2016, we received the Revenue Agent Report ("RAR") from the IRS. We believe that we have accurately reported all amounts in our tax returns, and have submitted administrative protests with the IRS Office of Appeals contesting the examination team’s proposed adjustments. We intend to vigorously defend our reported positions, and believe the ultimate resolution of the adjustments proposed by the IRS examination team will not have a material adverse effect on our consolidated financial statements. We have also been informed by the IRS that our 2012 and 2013 tax returns will be examined, and we anticipate that examination beginning during 2017. The IRS examination team also completed its examination of two U.S. subsidiaries of Frontier Drilling for 2011, and proposed no changes to those returns.Paragon Offshore.

On August 1, 2014, Noble-UK completed the ~~Spin-off~~separation and spin-off of a majority of its standard specification offshore drilling business (the “Spin-off”) through a pro rata distribution of all of the ordinary shares of its wholly-owned subsidiary, Paragon Offshore, to the holders of Noble’s ordinary shares. In February 2016, Paragon Offshore sought approval of ~~the~~ a pre-negotiated plan of reorganization (the “Prior Plan”) by filing for voluntary relief under Chapter 11 of the United States Bankruptcy Code. As part of the Prior Plan, we entered into ~~the Settlement Agreement~~a settlement agreement with Paragon Offshore under which, in exchange for a full and unconditional release of any claims by Paragon Offshore in connection with the Spin-off (including fraudulent conveyance claims that could be brought on behalf of Paragon Offshore’s creditors), we agreed to provide certain tax bonding in Mexico as well as assume certain tax liabilities and the administration of Mexican tax claims for specified years.(the “Settlement Agreement”). ~~The bonding to be provided by Noble-UK was a~~

~~key benefit to Paragon Offshore of the Settlement Agreement, which was subject to bankruptcy court confirmation as part of a bankruptcy plan.~~ The Prior Plan was rejected by the bankruptcy court in October 2016.

In April 2017, Paragon Offshore filed an updated disclosure statement and a ~~New Plan~~revised plan of reorganization (the “New Plan”) in its bankruptcy proceeding. Under the New Plan, including Paragon Offshore’s revised business plan, Paragon Offshore ~~will~~ no longer ~~need~~needed the Mexican tax bonding that ~~Noble~~Noble-UK was to provide under the Settlement Agreement. As a result, the Settlement Agreement iswas no longer applicable to the ~~anticipated~~ ongoing business of Paragon Offshore. Consequently, Paragon Offshore abandoned the Settlement Agreement as part of the New Plan, and the Settlement Agreement was terminated at the time of the filing of the New Plan. On May 2, 2017, Paragon Offshore announced that it had reached an agreement in principle with both its secured and unsecured creditors to revise the New Plan to, among other things, create and fund a $10.0 million litigation trust to pursue litigation against us. On June 7, 2017, the revised New Plan was approved by the bankruptcy court and Paragon Offshore emerged from bankruptcy on July 18, 2017.

~~We continue to discuss our continuing relationship with Paragon Offshore, including the possibility of entering into a new settlement agreement.~~On December 15, There can be no assurance that we will reach any settlement agreement with Paragon Offshore. If we do not enter into a settlement agreement with Paragon Offshore, we expect Paragon Offshore or its creditors would use the funds in2017, the litigation trust ~~to pursue~~filed claims ~~against us~~ relating to the Spin-off ~~including any~~against us and certain of our current and former officers and directors in the Delaware bankruptcy court that heard Paragon Offshore’s bankruptcy. The complaint alleges claims of alleged actual and constructive fraudulent conveyance, ~~claims.~~unjust enrichment and recharacterization of intercompany notes as equity claims against Noble and claims of breach of fiduciary duty and aiding and abetting breach of fiduciary duty against the officer and director defendants. We continue to believe that Paragon Offshore, at the time of the Spin-off, was properly funded, solvent and had appropriate liquidity and that ~~any fraudulent conveyance claim or other claim related to~~ the ~~Spin-off that may be~~claims brought by ~~Paragon Offshore or its creditors would be~~the litigation trust are without merit and ~~would~~will be contested vigorously by us.

We are entering into the discovery phase of the litigation. The presiding court has approved a litigation schedule which, if followed, would conclude all pre-trial motions and other activity by approximately the end of the third quarter of 2019. If any of the litigation ~~is instituted against Noble~~trust’s claims are successful, or if we elect to settle any claims, any damages or other amounts we would be required to or agree to pay could have a material adverse effect on our business, financial condition and ~~we are unsuccessful~~results of operations.

Such reserves may be substantial and could have a material adverse effect on our financial ~~position, results~~condition as presented in such financial statements.

Prior to the completion of ~~operations and/or cash flows.~~the Spin-off, Noble-UK and Paragon Offshore entered into a series of agreements to effect the separation and Spin-off and govern the relationship between the parties after the Spin-off (the “Separation Agreements”), including a Master Separation Agreement (the “MSA”) and a Tax Sharing Agreement (the “TSA”).

the MSA and the TSA in respect of obligations related to Paragon Offshore’s business that were incurred through Noble-retained entities prior to the Spin-off. ~~We could, however, pursue claims against Paragon Offshore for such indemnity amounts in the bankruptcy proceeding.

Tax matters.

During 2014, the Internal Revenue Service (“IRS”) began its examination of our tax reporting in the U.S. for the taxable years ended December 31, 2010 and 2011. The IRS examination team has completed its examination of our 2010 and 2011 U.S. tax returns and proposed adjustments and deficiencies with respect to certain items that were reported by us for the 2010 and 2011 tax year. On December 19, 2016, we received the Revenue Agent Report (“RAR”) from the IRS. We believe that we have accurately reported all amounts in our tax returns, and have submitted administrative protests with the IRS Office of Appeals contesting the examination team’s proposed adjustments. We intend to vigorously defend our reported positions, and believe the ultimate resolution of the adjustments proposed by the IRS examination team will not have a material adverse effect on our condensed consolidated financial statements. During the third quarter of 2017, the IRS initiated its examination of our 2012, 2013, 2014 and 2015 tax returns.

Audit claims of approximately ~~$49~~$52.8 million attributable to income and other business taxes have been assessed against Noble entities in Mexico. In addition, under the TSA, we must indemnify Paragon Offshore for final assessed amounts in respect of approximately $9 million of tax audit claims arising from Noble's Mexican business that was conducted through Paragon Offshore-retained entities prior to the Spin-off. If the Separation Agreements, including the TSA, are terminated, we would no longer have an obligation to indemnify Paragon Offshore for such amounts.

In January 2015, Noble received an official notification of a ruling from the Second Chamber of the Supreme Court in Mexico. The ruling settled an ongoing dispute in Mexico relating to the classification of a Noble subsidiary’s business activity and the applicable rate of depreciation under the Mexican law applicable to the activities of that subsidiary. The ruling did not result in any additional tax liability to Noble. Additionally, the ruling is only applicable to the Noble subsidiary named in the ruling and, therefore, does not establish the depreciation rate applicable to the assets of other Noble subsidiaries. We will continue to contest future assessments received, and can make no assurances regarding the ultimate outcome of these tax claims or our obligations to pay additional taxes in respect of these tax claims.

Paragon Offshore has received certain tax assessments attributable to income, customs and other business taxes in Brazil, including $46 million relating to Noble’s business that operated through a Paragon Offshore-retained entity in Brazil prior to the Spin-off. Under the TSA, we must indemnify Paragon Offshore for all final assessed amounts that are related to Noble’s Brazil business if and when such payments become due. If the Separation Agreements, including the TSA, are terminated, we would no longer have an obligation to indemnify Paragon Offshore for such amounts.

~~We have contested, or~~ intend to ~~contest or cooperate with Paragon Offshore in Brazil where it is contesting, the assessments described above, including through litigation if necessary,~~vigorously defend our reported positions, and we believe the ultimate resolution ~~for which we have not made any accrual,~~of the audit claims will not have a material adverse effect on our ~~consolidated financial statements.

We have been notified by Petrobras that it is currently challenging assessments by Brazilian tax authorities of withholding taxes associated with the provision of drilling rigs for its operations in Brazil during 2008 and 2009. Petrobras has also notified us that if Petrobras must ultimately pay such withholding taxes, it will seek reimbursement from us for the portion allocable to our drilling rigs. The amount of withholding tax that Petrobras indicates may be allocable to Noble drilling rigs is approximately $25 million. We believe that our contract with Petrobras requires Petrobras to indemnify us for these withholding taxes. We will, if necessary, vigorously defend our rights.

We maintain certain insurance coverage against specified marine perils, which includes physical damage and loss of hire to our drilling rigs along with other associated coverage common in our industry. We maintain a physical damage deductible on our rigs of $25 million per occurrence. With respect to the U.S. Gulf of Mexico, hurricane risk has generally resulted in more restrictive and expensive coverage for U.S. named windstorm perils, and we have opted in certain years to maintain limited or no windstorm coverage. Our current program provides for $500 million in named windstorm coverage in the U.S. Gulf of Mexico. The loss of hire coverage applies only to our rigs operating under contract with a dayrate equal to or greater than $200,000 a day and is subject to a 45-day waiting period for each unit and each occurrence.

Although we maintain insurance in the geographic areas in which we operate, pollution, reservoir damage and environmental risks generally are not fully insurable. Our insurance policies and contractual rights to indemnity may not adequately cover our losses or may have exclusions of coverage for some losses. We do not have insurance coverage or rights to indemnity for all risks, including loss of hire insurance on most of the rigs in our fleet. Uninsured exposures may include expatriate activities prohibited by U.S. laws and regulations, radiation hazards, certain loss or damage to property on board our rigs and losses relating to shore-based terrorist acts, strikes or cyber risks. If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it could materially adversely affect our financial position, results of operations or cash flows. Additionally, there can be no assurance that those parties with contractual obligations to indemnify us will necessarily be financially able to indemnify us against all these risks.

We carry protection and indemnity insurance covering marine third party liability exposures, which also includes coverage for employer’s liability resulting from personal injury to our offshore drilling crews. Our protection and indemnity policy currently has a standard deductible of $10 million per occurrence, with maximum liability coverage of $750 million.matters.

We have entered into agreements with certain of our executive officers, as well as certain other employees. These agreements become effective upon a change of control of Noble-UK (within the meaning set forth in the agreements) or a termination of employment in connection with or in anticipation of a change of control, and remain effective for three years thereafter. These agreements provide for compensation and certain other benefits under such circumstances.

~~Note 15 — Accounting Pronouncements~~

~~In May 2014,~~We are a defendant in certain claims and litigation arising out of operations in the ~~FASB issued ASU No. 2014-09,~~ordinary course of business, including personal injury claims, the resolution of which, ~~creates Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers,” and supersedes~~in the ~~revenue recognition requirements in Topic 605, “Revenue Recognition,” including most industry-specific revenue recognition guidance throughout the Industry Topics~~opinion of the Codification. In addition, ASU No. 2014-09 supersedes the cost guidance in Subtopic 605-35, “Revenue Recognition—Construction-Type and Production-Type Contracts,” and creates new Subtopic 340-40, “Other Assets and Deferred Costs—Contracts with Customers.” In summary, the core principle of Topic 606 ismanagement, will not be material to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The amendments in ASU No. 2014-09 are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and early application is permitted for periods beginning after December 15, 2016. We have formed an implementation work team, completed training on ASC Topic 606 and have begun a project to review relevant contracts. We plan on adopting the new standard effective January 1, 2018 concurrently with ASU No. 2016-02, Leases (ASC Topic 842) as discussed below and applying it retrospectively to all comparative periods presented.

In November 2015, the FASB issued ASU No. 2015-17, which amends ASC Topic 740, “Income Taxes.” This amendment aligns the presentation of deferred income tax assets and liabilities with International Financial Reporting Standards. International Accounting Standard 1, ~~Presentation of Financial Statements~~, requires deferred tax assets and liabilities to be classified as noncurrent in a classified statement of financial position. The current requirement that deferred tax liabilities and assets be offset and presented as a single amount is not affected by the amendments in this update. The standard is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. The amendments in this update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The adoption of this guidance did not have an impact on our financial ~~condition,~~position, results of operations ~~cash flows~~ or ~~financial disclosures and we determined that there is no retrospective adjustment necessary, as such, the update will be implemented prospectively.~~

In February 2016, the FASB issued ASU No. 2016-02, which creates ASC Topic 842, “Leases.” This update increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018. Under the updated accounting standards, we have preliminarily determined that our drilling contracts contain a lease component, and our adoption, therefore, will require that we separately recognize revenues associated with the lease and services components. Our adoption, and the ultimate effect on our consolidated financial statements, will be based on an evaluation of the contract-specific facts and circumstances, and such effect could result in differences in the timing of our revenue recognition relative to current accounting standards. Given the interaction with the accounting standard update related to revenue from contracts with customers, we expect to adopt the updates concurrently, effective January 1, 2018. We are evaluating what impact the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures. We have formed an implementation work team, completed training on ASC Topic 842 and have begun a project to review relevant leases.

In March 2016, the FASB issued ASU No. 2016-05, which amends ASC Topic 815, “Derivatives and Hedging.” This amendment clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance is effective for interim and annual reporting periods beginning after December 15, 2016 and may be applied on either a prospective basis or a modified retrospective basis. The adoption of this guidance did not have an impact on our financial condition, results of operations, cash flows or financial disclosures and we determined that there is no retrospective adjustment necessary, as such, the update will be implemented prospectively.

In March 2016, the FASB issued ASU No. 2016-09, which amends ASC Topic 718, “Compensation – Stock Compensation.” This amendment simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ~~This guidance~~There is ~~effective for interim~~inherent risk in any litigation or dispute and ~~annual reporting periods beginning after December 15, 2016. Under the new provision, current period excess tax benefits related to stock compensation will~~no assurance can be recognized in the “Provision for income taxes” in the results of operations, rather than in "Additional paid-in capital" in the consolidated balance sheets and will be applied on a prospective basis. Changesgiven as to the ~~statements~~outcome of cash flows related to the classification of prior period excess tax benefits and employee taxes paid for share-based payment arrangements will be implemented on a retrospective basis. In accordance with our adoption of this update, in the accompanying Consolidated Statement of Cash Flows, excess tax benefits of approximately $5.5 million as of March 31, 2016, which were previously classified as a financing activity in “Employee stock transactions,” are classified as an operating activity in “Other current liabilities.” Additionally, employee taxes paid for share-based payment arrangements of approximately $3 million as of March 31, 2016, which were previously classified as an operating activity in “Other current liabilities,” are classified as a financing activity in “Employee stock transactions”.

In August 2016, the FASB issued ASU No. 2016-15 which amends ASC Topic 230, “Classification of Certain Cash Receipts and Cash Payments.” The amendments in this update address eight specific cash flow issues with the objective of reducing the existing diversity in practice. The update outlines the classification of specific transactions as either cash inflows or outflows from financing activities, operating activities, investing activities or non-cash activities. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures.

In October 2016, the FASB issued ASU No. 2016-16 which amends ASC Topic 740, “Income Taxes.” The amendments in this update improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures.

In November 2016, the FASB issued ASU No. 2016-18 which amends ASC Topic 230, “Classification of Certain Cash Receipts and Cash Payments.” The amendments in this update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures.

In February 2017, the FASB issued ASU No. 2017-06 which amends ASC Topic 960, “Defined Benefit Pension Plans," ASC Topic 962, "Defined Contribution Pension Plans" and ASC Topic 965, "Health and Welfare Benefit Plans." The amendments in this update clarify presentation requirements for a plan’s interest in a master trust and require more detailed disclosures of the plan’s interest in the master trust. The amendments also eliminate a redundancy relating to 401(h) account disclosures. This guidance

is effective for fiscal years beginning after December 15, 2018. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures.

In March 2017, the FASB issued ASU No. 2017-07 which amends ASC Topic 715, “Compensation—Retirement Benefits." The amendments in this update require that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017. We are evaluating what impact, if any, the adoption of this guidance will have on our financial condition, results of operations, cash flows or financial disclosures.these claims.

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

The following discussion is intended to assist you in understanding our financial position at March 31, ~~2017,~~2018, and our results of operations for the three months ended March 31, ~~2017~~2018 and ~~2016.~~2017. The following discussion should be read in conjunction with the condensed consolidated financial statements and related notes contained in this Quarterly Report on Form 10-Q and the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, ~~2016~~2017 filed by Noble Corporation plc, a public limited company incorporated under the laws of England and Wales (“Noble-UK”), and Noble Corporation, a Cayman Islands company (“Noble-Cayman”).

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended. All statements other than statements of historical facts included in this report or in the documents incorporated by reference, including those regarding rig demand, the offshore drilling market, oil prices, contract backlog, fleet status, our future financial position, business strategy, impairments, repayment of debt, credit ratings, borrowings under our ~~credit facility~~Credit Facilities (as defined herein) or other instruments, sources of funds, future capital expenditures, contract commitments, dayrates, contract commencements, extension or renewals, contract tenders, the outcome of any dispute, litigation, audit or investigation, plans and objectives of management for future operations, foreign currency requirements, results of joint ventures, indemnity and other contract claims, reactivation, refurbishment, conversion and upgrade of rigs, industry conditions, access to financing, impact of competition, governmental regulations and permitting, availability of labor, worldwide economic conditions, taxes and tax rates, indebtedness covenant compliance, dividends and distributable reserves, timing or results of acquisitions or dispositions, and timing for compliance with any new regulations are forward-looking statements. When used in this report, or in the documents incorporated by reference, the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “should” and similar expressions are intended to be among the statements that identify forward-looking statements. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot assure you that such expectations will prove to be correct. These forward-looking statements speak only as of the date of this report on Form 10-Q and we undertake no obligation to revise or update any forward-looking statement for any reason, except as required by law. We have identified factors including but not limited to market conditions, factors affecting the level of activity in the oil and gas industry, supply and demand of drilling rigs, factors affecting the duration of contracts, the actual amount of downtime, factors that reduce applicable dayrates, operating hazards and delays, risks associated with operations outside the U.S., actions by regulatory authorities, credit rating agencies, customers, joint venture partners, contractors, lenders and other third parties, legislation and regulations affecting drilling operations, violations of anti-corruption laws, hurricanes and other weather conditions and the future price of oil and gas that could cause actual plans or results to differ materially from those included in any forward-looking statements. These factors include those referenced or described in Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, ~~2016,~~2017, our Quarterly Reports on Form 10-Q and in our other filings with the U.S. Securities and Exchange Commission (“SEC”). We cannot control such risk factors and other uncertainties, and in many cases, we cannot predict the risks and uncertainties that could cause our actual results to differ materially from those indicated by the forward-looking statements. You should consider these risks and uncertainties when you are evaluating us.

Executive Overview

We ~~are a leading offshore~~provide contract drilling ~~contractor for~~services to the international oil and gas ~~industry. We perform contract drilling services~~industry with our global fleet of mobile offshore drilling units. As of ~~May 5, 2017,~~the filing date of this Quarterly Report on Form 10-Q, our fleet of 28 drilling rigs consisted of eight drillships, six semisubmersibles and 14 jackups ~~eight drillships and six semisubmersibles.~~strategically deployed worldwide. We typically employ each drilling unit under an individual contract. Although the final terms of the contracts result from negotiations with our customers, many contracts are awarded based upon a competitive bidding process.

Outlook

The challenging business environment for offshore drillers ~~during~~continued through the first ~~three~~four months of ~~2017 remained challenging. A~~2018. An industry-wide rig supply imbalance has remained in place, as curtailed offshore spending by customers contributed to a ~~growing~~significant number of rigs without ~~follow-on~~ drilling ~~programs as current contracts expire.~~programs. In addition, ~~some~~ newbuild rigs ordered prior to the decline in industry activity continue to exit shipyards, including those newbuilds now owned by the constructing shipyards which seek buyers for their stranded rigs, while the delivery of other newbuild ~~orders~~rigs have been delayed into the ~~future and are adding~~future. These rigs add to the supply ~~imbalanc~~imbalance. Since 2015, the industry has experienced a higher level of fleet attrition, as rigs are removed from the global supply due to a number of factors, including advanced service life, high maintenance and reactivation costs and limited customer appeal.

e. ~~Our~~However, the pace of attrition has been significantly less than what is required to ameliorate the capacity imbalance. In addition, our customers have adopted a cautious approach to offshore spending as crude oil prices have declined from approximately $112 per barrel for Brent crude on June 30, 2014 to as low as approximately $30 per barrel in January 2016, before improving to ~~$52~~$73 per barrel on ~~April 25, 2017.~~May 2, 2018. Although crude oil prices have ~~traded in a more sustainable range over~~moved higher during 2017 and the first ~~three~~four months of

~~2017,~~ 2018, we expect that the offshore drilling programs of operators will remain curtailed ~~especially exploration activity, until higher, sustainable crude oil prices are achieved. Until then,~~as our customers continue to favor cash flow realization over long cycle investment in offshore production and exploration. While further ~~deterioration~~decline in rig utilization and dayrates is ~~possible.~~possible due to the continued oversupply of rigs, we expect that a gradual improvement in customer spending offshore is likely to occur over the near to medium term.

WeIn spite of the gradual improvement in offshore spending, we expect the business environment for the remainder of ~~2017 and into~~ 2018 to remain ~~weak and it could potentially deteriorate further.~~challenging. The ~~present subdued level of global economic activity, the~~ uncertainty of the viability and length of reductions in production agreed to by the Organization of Petroleum Exporting Countries (“OPEC”) ~~in November 2016,~~, the incremental production capacity in non-OPEC countries, including growing production from ~~the~~ U.S. shale activity, the current U.S. political environment and fluid sentiment in oil markets have led to only modest increases in offshore investment. However, steady demand growth, the ~~Brexit vote~~lack of production investments in various countries around the ~~UK are contributing to an uncertain oil price environment, leading to considerable uncertainty in our customers’ exploration~~world and ~~production spending plans. However,~~ the production limits ~~recently~~ agreed to by OPEC ~~could help~~and other significant oil producing countries have helped to establish market conditions supporting higher sustained crude prices ~~in 2017.~~and should lead to improved offshore spending by our customers. In general, recent contract awards have been ~~short-term in nature and~~ subject to an extremely competitive bidding process. As a result, the contracts have been for dayrates that are substantially lower than rates were for the same class of rigs before this period of imbalance. We cannot give any assurances as to when conditions in the offshore drilling market will improve, the extent of any market improvement or when the oversupply of available drilling rigs will end. While current market conditions persist, we will continue to focus on fleet utilization improvements, cost control initiatives and ~~managing~~financial discipline, including the preservation of liquidity. The current business environment could lead to ~~the Company~~us stacking or retiring additional ~~drilling~~ rigs.

~~While~~However, we ~~cannot predict the future level of demand or dayrates for our services, or future conditions in the offshore contract drilling industry, we believe we are strategically well positioned.~~

Results and Strategy

Our business strategy focuses on a balanced, high-specification fleet of both ~~deepwater~~floating and ~~high-specification~~ jackup ~~assets~~rigs and the deployment of our drilling rigs in ~~important~~ oil and gas basins around the world. We emphasize safe operations through the employment of quality, well-trained crews and strive to manage rig operating costs through the practice of innovative systems and processes, including the use of data analytics and predictive maintenance technology. Our strategy includes a focus on managing business cyclicality through available liquidity and access to capital.

Spin-off of Paragon Offshore plc

On August 1, 2014, Noble-UK completed the separation and spin-off of a majority of its standard specification offshore drilling business (the ~~“Spin-off”~~“Spin-Off”) through a pro rata distribution of all of the ordinary shares of its wholly-owned subsidiary, Paragon Offshore plc (“Paragon Offshore”), to the holders of Noble’s ordinary shares.

In February 2016, Paragon Offshore sought approval of a pre-negotiated plan of reorganization (the ~~"Prior Plan"~~“Prior Plan”) by filing for voluntary relief under Chapter 11 of the United States Bankruptcy Code. As part of the Prior Plan, we entered into a settlement agreement with Paragon Offshore (the ~~"Settlement Agreement"~~“Settlement Agreement”) under which, in exchange for a full and unconditional release of any claims by Paragon Offshore in connection with the Spin-off (including fraudulent conveyance claims that could be brought on behalf of Paragon Offshore’s creditors), we agreed to provide certain tax bonding in Mexico as well as assume certain tax liabilities and the administration of Mexican tax claims for specified years.. ~~The bonding to be provided by Noble-UK was a key benefit to Paragon Offshore of the Settlement Agreement, which was subject to bankruptcy court confirmation as part of a bankruptcy plan.~~ The Prior Plan was rejected by the bankruptcy court in October 2016.

In April 2017, Paragon Offshore filed an updated disclosure statement and a revised plan of reorganization (the “New Plan”) in its bankruptcy proceeding. Under the New Plan, including Paragon Offshore’s revised business plan, Paragon Offshore ~~will~~ no longer ~~need~~needed the Mexican tax bonding that Noble-UK was to provide under the Settlement Agreement. As a result, the Settlement Agreement iswas no longer applicable to the ~~anticipated~~ ongoing business of Paragon Offshore. Consequently, Paragon Offshore abandoned the Settlement Agreement as part of the New Plan, and the Settlement Agreement was terminated at the time of the filing of the New Plan. On May 2, 2017, Paragon Offshore announced that it had reached an agreement in principle with both its secured and unsecured creditors to revise the New Plan to, among other things, create and fund a $10.0 million litigation trust to pursue litigation against us.

~~We continue to discuss our continuing relationship with~~ On June 7, 2017, the revised New Plan was approved by the bankruptcy court and Paragon Offshore ~~including the possibility of entering into a new settlement agreement.~~emerged from bankruptcy on July 18, 2017.

On December 15, There can be no assurance that we will reach any settlement agreement with Paragon Offshore. If we do not enter into a settlement agreement with Paragon Offshore, we expect Paragon Offshore or its creditors would use the funds in2017, the litigation trust ~~to pursue~~filed claims ~~against us~~ relating to the Spin-off ~~including any~~against us and certain of our current and former officers and directors in the Delaware bankruptcy court that heard Paragon Offshore’s bankruptcy. The complaint alleges claims of alleged actual and constructive fraudulent conveyance, ~~claims.~~unjust enrichment and recharacterization of intercompany notes as equity claims against Noble and claims of breach of fiduciary duty and aiding and abetting breach of fiduciary duty against the officer and director defendants. We co

~~ntinue~~ continue to believe that Paragon Offshore, at the time of the Spin-off, was properly funded, solvent and had appropriate liquidity and that ~~any fraudulent conveyance claim or other claim related to~~ the ~~Spin-off that may be~~claims brought by ~~Paragon Offshore or its creditors, would be~~the litigation trust are without merit and ~~would~~will be contested vigorously by us.

We are entering into the discovery phase of the litigation. The presiding court has approved a litigation schedule which, if followed, would conclude all pre-trial motions and other activity by approximately the end of the third quarter of 2019. If any of the litigation trust’s claims are successful, or if we elect to settle any claims, any damages or other amounts we would be required to or agree to pay could have a material adverse effect on our business, financial condition and results of operations. We may be required to establish reserves on our financial statements in advance of the conclusion of the litigation. Such reserves may be substantial and could have a material adverse effect on our financial condition as presented in such financial statements.

Prior to the completion of the Spin-off, Noble-UK and Paragon Offshore entered into a series of agreements to effect the separation and Spin-off and govern the relationship between the parties after the Spin-off (the ~~"Separation Agreements"~~“Separation Agreements”), including a Master Separation Agreement (the “MSA”) and a Tax Sharing Agreement (the “TSA”). ~~In the course~~

As part of its final bankruptcy plan, Paragon Offshore ~~may elect to reject~~rejected the Separation Agreements. ~~If Paragon Offshore rejects the Separation Agreements,~~Accordingly, the indemnity obligations that Paragon Offshore ~~may owe~~potentially would have owed us under the Separation Agreements ~~would terminate,~~have now terminated, including indemnities arising under the ~~Master Separation Agreement~~MSA and the ~~Tax Sharing Agreement~~TSA in respect of obligations related to Paragon Offshore’s business that were incurred through Noble-retained entities prior to the Spin-off. ~~We could, however, pursue claims against Paragon Offshore for such indemnity amounts in the bankruptcy proceeding. Any such claims would be unsecured claims in the bankruptcy.~~ Likewise, any potential indemnity obligations that we ~~may owe~~would have owed Paragon Offshore under the Separation Agreements, including those under the ~~Master Separation Agreement~~MSA and ~~Tax Sharing Agreement~~the TSA in respect of Noble-UK’s business that was conducted prior to the Spin-off through Paragon Offshore-retained entities, are now also extinguished. In the absence of the Separation Agreements, liabilities relating to the respective parties will be borne by the owner of the legal entity or asset at issue and neither party will look to an allocation based on the historic relationship of an entity or asset to one of the party’s business, as had been the case under the Separation Agreements.

~~For additional information regarding the Spin-off and the Settlement Agreement with Paragon Offshore, see Note 2 and Note 14 to the consolidated financial statements included in this report.~~

Contract Drilling Services Backlog

We maintain a backlog ~~(as defined below)~~ of commitments for contract drilling services. ~~The following table sets forth,~~Our contract drilling services backlog reflects estimated future revenues attributable to signed drilling contracts. While backlog did not include any letters of intent as of March 31, ~~2017,~~2018, in the past we have included in backlog certain letters of intent that we expect to result in binding drilling contracts.

We calculate backlog for any given unit and period by multiplying the full contractual operating dayrate for such unit by the number of days remaining in the period, and for the three rigs contracted with Royal Dutch Shell plc (“Shell”) mentioned below, we utilize the idle period and floor rates as described in Footnote (4) to the backlog table below. The reported contract drilling services backlog does not include amounts representing revenues for mobilization, demobilization and contract preparation, which are not expected to be significant to our contract drilling services revenues, amounts constituting reimbursables from customers or amounts attributable to uncommitted option periods under drilling contracts or letters of intent.

The table below presents, the amount of our contract drilling services backlog and the percent of available operating days committed for the periods indicated:

⁽¹⁾	Represents a nine-month period beginning April 1, ~~2017.~~2018.


~~(2)~~	Some of our drilling contracts provide the customer with certain early termination rights and, in very limited cases, these termination rights require minimal or no notice or financial penalties. As of April 25, 2017, no notifications of contract terminations have been received.


~~(3)~~	~~Our Saudi Aramco contract rates for the~~⁽²⁾ ~~Noble Joe Beall~~ ~~and~~ ~~Noble Gene House~~ were adjusted downward in 2016. We expect the contract rates to be in the general range of the amended rates in 2016 through the end of each respective contract. Backlog for these contracts has been prepared assuming the reduced rates from 2016 apply for the remainder of the contract.

~~(4)~~

As previously reported, three of our long-term drilling contracts with Shell, the Noble Bully II, Noble Globetrotter I and Noble Globetrotter II, contain a dayrate adjustment mechanism that utilizes an average of market rates that match a set of distinct technical attributes and is subject to a modest discount, beginning on the ~~fifth year~~fifth-year anniversary of the contract and continuing every six months thereafter. On December 12, 2016, we amended those ~~long-term~~drilling contracts with Shell. As a result of the amendments, each of the contracts now has a contractual dayrate floor. The contract amendments for the Noble Globetrotter I and Noble Globetrotter II provide a dayrate floor of $275,000 per day. The Noble Bully II contract contains a dayrate floor of $200,000 per day plus daily operating expenses. The amendment also provided Shell the right to idle the Noble Bully II for up to one year and the Noble Globetrotter II for up to two years, each at a special stacking rate. Shell has exercised its right and, beginning late December 2016, we idled the Noble Globetrotter II at a rate of $185,000 per day. The Noble Bully II was idled at a rate of $200,000 per day, effective April 3, 2017. Once the dayrate adjustment

mechanism becomes effective and following any idle periods, the dayrate for these rigs will not be lower than the higher of (i) the contractual dayrate floor or (ii) the market rate as calculated under the adjustment mechanism. The impact to contract backlog from these amendments has been reflected in the table above and the backlog calculation assumes that, after any idle period at the contractual stacking rate, each rig will work at their respective dayrate floor for the remaining contract term.

~~(5)~~

~~Percent~~ of ~~available days committed is~~(i) the contractual dayrate floor or (ii) the market rate as calculated ~~by dividing~~under the ~~total number~~adjustment mechanism. The impact to contract backlog from these amendments has been reflected in the table above and the backlog calculation assumes that, after any idle period at the contractual stacking rate, each rig will work at their respective dayrate floor for the remaining contract term. In April 2018, we agreed with Shell to extend the idle period for the Noble Bully II through December 31, 2018 at a revised rate of ~~days our rigs are operating under contract for such period by the product~~$230,000 per day. This extension of the ~~number of our rigs and~~idle period would have reduced the ~~number of calendar days in such period.~~March 31, 2018 backlog by approximately $30 million.

Noble and a subsidiary of Shell are involved in joint ventures that own and operate both the Noble Bully I and the Noble Bully II. Pursuant to these agreements, each party has an equal 50 percent share in both vessels. As of March 31, ~~2017,~~2018, the ~~combined amount of~~ backlog for ~~these rigs~~the Noble Bully II totaled ~~$573~~$498.0 million, all of which is included in backlog. As of the same date, the Noble Bully I had no backlog. Noble’s proportional interest in the backlog for these rigs totaled ~~$286.5~~$249.0 million.


⁽⁴⁾	Our Saudi Arabian Oil Company (“Saudi Aramco”) contract rates for the Noble Joe Beall and the Noble Gene House were adjusted downward in 2015 and remained at these same rates through the end of the respective contracts. Backlog for these contracts has been prepared based on the adjusted contract rates through the remainder of the contracts.


⁽⁵⁾	Some of our drilling contracts provide the customers with certain early termination rights and, in limited cases, those termination rights require minimal or no notice and financial penalties. As of May 2, 2018, no new notifications of contract terminations have been received.


⁽⁶⁾	Percent of available days committed is calculated by dividing the total number of days our rigs are operating under contract for such period by the product of the number of our rigs and the number of calendar days in such period.

Our contract drilling services backlog reflects estimated future revenues attributable to both signed drilling contracts and letters of intent that we expect to result in binding drilling contracts. A letter of intent is generally subject to customary conditions, including the execution of a definitive drilling contract. It is possible that some customers that have entered into letters of intent will not enter into signed drilling contracts. As of March 31, 2017, our contract drilling services backlog did not include any letters of intent.

We calculate backlog for any given unit and period by multiplying the full contractual operating dayrate for such unit by the number of days remaining in the period and, for the three rigs contracted with Shell mentioned in the above, utilize the idle period and floor rates as described in Footnote (4) to the Backlog table above. The reported contract drilling services backlog does not include amounts representing revenues for mobilization, demobilization and contract preparation, which are not expected to be significant to our contract drilling services revenues, amounts constituting reimbursables from customers or amounts attributable to uncommitted option periods under drilling contracts or letters of intent.

The amount of actual revenues earned and the actual periods during which revenues are earned may be materially different than the backlog amounts and backlog periods ~~set forth~~presented in the table above due to various factors, including, but not limited to, shipyard and maintenance projects, unplanned downtime, the operation of market benchmarks for dayrate resets, achievement of bonuses, weather conditions, reduced standby or mobilization rates and other factors that result in applicable dayrates lower than the full contractual operating dayrate. In addition, amounts included

in the backlog may change because drilling contracts may be varied or modified by mutual consent or customers may exercise early termination rights contained in some of our drilling contracts or decline to enter into a drilling contract after executing a letter of intent. As a result, our backlog as of any particular date may not be indicative of our actual operating results for the periods for which the backlog is calculated. See Part I, Item 1A, “Risk Factors – ~~We can provide no assurance that our~~Our current backlog of contract drilling revenue ~~will~~may not be ultimately realized” in our Annual Report on Form 10-K for the year ended December 31, ~~2016.~~2017.

As of March 31, ~~2017,~~2018, Shell, Saudi Aramco and Statoil ASA represented approximately 5957.4 percent, 1918.4 percent and 1514.0 percent of our backlog, respectively.

Results of Operations

For the Three Months Ended March 31, ~~2017~~2018 and ~~2016~~2017

Net loss from continuing operations attributable to Noble-UK for the three months ended March 31, 2018 was $142.3 million, or $0.58 per diluted share, on operating revenues of $235.2 million, compared to net loss from continuing operations for the three months ended March 31, 2017 ~~(the “Current Quarter”) was $302~~of $301.7 million, or $1.24 per diluted share, on operating revenues of $363 million, compared to net income from continuing operations for the three months ended March 31, 2016 (the “Comparable Quarter”) of $105 million, or $0.42 per diluted share, on operating revenues of $612$363.0 million.

As a result of Noble-UK conducting all of its business through Noble-Cayman and its subsidiaries, the financial position and results of operations for Noble-Cayman, and the reasons for material changes in the amount of revenue and expense items between ~~the Current Quarter~~March 31, 2018 and ~~the Comparable Quarter,~~March 31, 2017, would be the same as the information presented below regarding Noble-UK in all material respects, ~~except~~with the exception of operating ~~income for Noble-Cayman for~~income. During the three months ended March 31, 2018 and 2017, Noble-Cayman's operating loss was $10.2 million lower and ~~2016~~operating income was ~~$7 million and $12~~$7.2 million higher, respectively, than ~~operating income for Noble-UK for the same periods.~~that of Noble-UK. The operating income or loss difference is primarily a result of ~~executive~~administration and other costs directly attributable to Noble-UK for operations support and ~~stewardship related~~stewardship-related services.

~~Rig Utilization,~~Key Operating ~~Days and Average Dayrates~~Metrics

Operating Revenues. ~~Changes~~The $125.6 million decline in contract drilling services revenues for the ~~Current Quarter~~three months ended March 31, 2018 as compared to the ~~Comparable Quarter were driven by~~same period of 2017 was composed of an $8.2 million decline from lower dayrates and a ~~29 percent decrease~~$117.4 million decline due to fewer operating days. The contract drilling services revenues decline was primarily due to our drillship and jackup fleet, which experienced declines in revenues of $87.1 million and $35.6 million, respectively. Our semisubmersible fleet experienced a decline in revenue of $2.9 million.

The $87.1 million revenue decline in our drillship fleet consists of a $40.5 million decline from lower dayrates and a $46.6 million decline due to fewer operating days for the three months ended March 31, 2018 compared to the same period of 2017. The declines in average dayrates ~~which decreased revenues by $148 million as well as a 15 percent decrease in~~and operating days ~~which decreased revenues by $89 million. Contract drilling services revenues decreased in the Current Quarter as compared~~were primarily related to ~~the Comparable Quarter by $170 million and $79 million on our drillships and semisubmersibles, respectively, and increased by $12 million on our jackups.~~

During the Current Quarter drillship revenues decreased by $170 million driven by a 33 percent decrease in operating days and a 20 percent decrease in average dayrates, resulting in decreases in revenues of $121 million and $49 million, respectively, from the Comparable Quarter. The decrease in both operating days and average dayrates was primarily the result of the contract cancellations of the ~~Noble Sam Croft,Noble Tom Madden~~ ~~and~~ ~~Noble Bob Douglas,~~ ~~which operated in the Comparable Quarter and increased stacked days on~~ the Noble Bully I, inwhich remained stacked during the ~~Current Quarter. Additionally,~~current period but operated during the ~~valuation~~same period of 2017. In addition, the ~~contingent payments from the FCX Settlement declined $8 million in the Current Quarter.~~

~~Semisubmersible revenues decreased by $79 million, driven by~~ Noble Bob Douglas experienceda ~~74 percent decrease in operating days and a 49 percent~~ decrease in average dayrates ~~resulting~~and operating days during the current period compared the same period of 2017.

The $35.6 million revenue decline in our jackup fleet is primarily attributable to a ~~$67~~$57.1 million ~~and $12 million decrease~~decline in revenues ~~respectively, from the Comparable Quarter. The decrease in both~~due to certain of our jackup rigsnot operating ~~days and average dayrates was attributable to the contract completions since the Comparable Quarter for the~~ ~~Noble Jim Day~~, ~~Noble Clyde Boudreaux~~, ~~Noble Amos Runner~~, ~~Noble Dave Beard~~ ~~and~~ ~~Noble Danny Adkins,~~ ~~each of which has not returned to work since their respective completions. Additionally, decreases~~ in the current period, but operating during the same period of 2017, which was partially offset by an increase in revenues of $21.5 million associated with favorable dayrate ~~for~~changes across the jackup fleet. The $2.9 million decline in semisubmersible revenues was due to dayrate decreases on the Noble Paul Romano ~~contributed to the decrease in average dayrates during the Current Quarter.~~

Jackup revenues increased by $12 million, driven by a 19 percent increase in operating days, resulting in a $26 million increase in revenues, which was partially offset by a nine percent decrease in average dayrates, resulting in a $14 million decrease in revenues in the Current Quarter from the Comparable Quarter. The increase in operating days was primarily driven by the commencement of the newbuilds ~~Noble Lloyd Noble~~ ~~and~~ ~~Noble Sam Hartley, which commenced their contracts in November 2016 and January 2016, respectively, as well as~~ ~~Noble Mick O'Brien~~ ~~and~~ ~~Noble Regina Allen,~~ ~~which operated during the Current Quarter but were off contract during the Comparable Quarter. This was partially offset by the~~ ~~Noble Tom Prosser~~, which was off contract during the Current Quarter but operated in the Comparable Quarter. The decrease in average dayrates was primarily driven by unfavorable dayrate changes on contracts across the jackup fleet..

Operating Costs and Expenses. Contract drilling services operating costs ~~and expenses~~ decreased ~~$91~~$23.9 million for the ~~Current Quarter~~three months ended March 31, 2018 as compared to the ~~Comparable Quarter. Costs decreased $66~~same period of 2017. Of the decrease, $24.3 million ~~for~~was due to rigs ~~that operated~~with significant operating days during the ~~Comparable Quarter but were idle~~first quarter of 2017, which had either no or ~~stacked during the Current Quarter. Additional cost control measures led to a cost reduction of $35 million across rigs with comparable~~fewer operating days in ~~both the Current Quarter and the Comparable Quarter.~~same quarter of 2018. These ~~cost~~ decreases were primarily recognized in labor and training related costs, operations support and repair and maintenance costs of approximately $13 million, $8 million and $5 million, respectively, as well as other rig-related expenses. This was partially offset by ~~the newly~~a $2.1 million increase in operating ~~rig, the~~ ~~Noble Lloyd Noble, which added~~ costs ~~of approximately $10 million~~.related to rigs idled in both periods.

~~The $14 million decrease in depreciation~~Depreciation and amortization indecreased $6.6 million for the ~~Current Quarter~~three months ended March 31, 2018 as compared to the ~~Comparable Quarter~~same period of 2017. The decline was ~~primarily attributable~~due to the ~~retirement and subsequent sale~~effect of ~~the~~ ~~Noble Max Smith~~ ~~and the retirement of the~~ ~~Noble Homer Ferrington, as well as the impairment of the~~ ~~Noble Amos Runner~~, ~~Noble Clyde Boudreaux~~ ~~and~~ ~~Noble Dave Beard~~ ~~in December 2016, partially offset by the newbuild~~ rig ~~the~~ ~~Noble Lloyd Noble, placed in service November 2016.~~impairments during 2017.

Interest ~~Expense, net of amount capitalized.~~Expense. Interest expense increased ~~$16~~$2.6 million induring the ~~Current Quarter~~three months ended March 31, 2018 as compared to the ~~Comparable Quarter~~same period of 2017.

The increase in applicable interest rates on certain of our senior notes due to the downgrading of our credit rating below investment grade in the prior year. We capitalized approximately six percent during the Comparable Quarter. These expense increases werewas partially offset by the retirement of a portion of our ~~2020, 2021 and 2022~~ Senior Notes due 2020 (the “2020 Notes”), Senior Notes due 2021 (the “2021 Notes”) and Senior Notes due 2022 (the “2022 Notes”) as a result of ~~two different~~ tender offers in January 2018, the ~~prior year, as well as the repayment~~maturity of our ~~maturing $300 million 3.05%~~ Senior Notes due 2018 (the “2018 Notes”) and the redemption of our ~~$300 million 2.50%~~remaining Senior Notes ~~in March 2016 and March 2017, respectively.~~due 2019 (the “2019 Notes”).

Liquidity and Capital Resources

Overview

Net cash provided by operating activities was ~~$142~~$54.9 million for the three months ended March 31, ~~2017 (“Current Period”)~~2018 and ~~$172~~$141.9 million for the three months ended March 31, ~~2016 (“Comparable Period”).~~2017. The decrease in net cash provided by operating activities infor the ~~Current Period~~three months ended March 31, 2018 was primarily attributable to ~~recognizing~~ a ~~net loss~~reduction in ~~the Current Period.~~operating activity during this period. We had working capital of ~~$415~~$426.0 million and ~~$559~~$446.0 million at March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, respectively.

Net cash used in investing activities infor the ~~Current Period~~three months ended March 31, 2018 was ~~$38~~$33.7 million as compared to ~~$86~~$38.1 million infor the ~~Comparable Period.~~three months ended March 31, 2017. The variance primarily relates to lower capital expenditures related to our major projects ~~and newbuild expenditures~~ in the ~~Current Period.~~current period.

Net cash used in financing activities infor the ~~Current Period~~three months ended March 31, 2018 was ~~$310~~$222.4 million as compared to ~~$362~~$309.7 million infor the ~~Comparable Period.~~three months ended March 31, 2017. During the ~~Current Period,~~current period, our primary uses of cash included retirement of a portion of the ~~repayment of our maturing $300 million 2.50% Senior~~2020 Notes, 2021 Notes, 2022 Notes and ~~dividends paid to noncontrolling interests~~2024 Notes in tender offers, repayment at maturity of ~~approximately $5 million.~~the 2018 Notes and redemption of the 2019 Notes, which amounts were partially offset by the issuance of the 2026 Notes.

Our principal source of capital in the ~~Current Period~~current period was cash generated from operating activities ~~and cash on hand.~~coupled with the $750.0 million 2026 Notes offering in January 2018. Cash on hand during the ~~Current Period~~current period was primarily used for the following:

normal recurring operating expenses;

~~repayment~~retirement of a portion of our ~~maturing $300 million 2.50% Senior~~2020 Notes, 2021 Notes, 2022 Notes and 2024 Notes in tender offers, repayment at maturity of the 2018 Notes and redemption of the 2019 Notes; and

capital expenditures.

Our currently anticipated cash flow needs, both in the short-term and long-term, may include the following:

normal recurring operating expenses;

planned and discretionary capital expenditures; and

~~repayment~~repayments of debt and interest.

We currently expect to fund these cash flow needs with cash generated by our operations, cash on hand, borrowings under our existing ~~credit facility~~Credit Facilities (as defined below) and potential issuances of long-term ~~debt or asset sales.~~debt. However, to adequately cover our expected cash flow needs, we may require capital in excess of the amount available from these sources, and we may seek additional sources of liquidity and/or delay or cancel certain discretionary capital expenditures or other payments as necessary.

At March 31, ~~2017,~~2018, we had a total contract drilling services backlog of approximately ~~$3.5 billion. Our backlog as of March 31, 2017~~$2.8 billion, which includes a commitment of 5451 percent of available days for the remainder of ~~2017~~2018 and 4029 percent of available days for ~~2018.~~2019. For additional information regarding our backlog, see “Contract Drilling Services Backlog.”

Capital Expenditures

Capital expenditures, ~~including capitalized interest,~~excluding the effect of accruals, totaled ~~$19~~$37.9 million and ~~$51~~$18.7 million for the three months ended March 31, ~~2017~~2018 and ~~2016,~~2017, respectively. Capital expenditures during the first three months of ~~2017~~2018 consisted of the following:

$918.2 million for sustaining capital and upgrades and replacements to drilling equipment;

$511.1 million in ~~subsea related expenditures;~~major projects; and

$58.6 million in ~~major~~other capital projects.

Our total capital expenditure estimate for ~~2017~~2018 is ~~approximately $115~~$147.8 million.

From time to time we consider possible projects that would require expenditures that are not included in our capital budget, and such unbudgeted expenditures could be significant. In addition, we will continue to evaluate acquisitions of drilling units from time to time. Other factors that could cause actual capital expenditures to materially exceed plan include delays and cost overruns in shipyards (including costs attributable to labor shortages), shortages of equipment, latent damage or deterioration to hull, equipment and machinery in excess of engineering

estimates and assumptions, changes in governmental regulations and requirements and changes in design criteria or specifications during repair or construction.

~~Dividends~~

~~During the fourth quarter of 2016, our Board of Directors eliminated our quarterly cash dividend.~~Share Capital

The declaration and payment of dividends require the authorization of the Board of Directors of Noble-UK, provided that such dividends on issued share capital may be paid only out of Noble-UK’s “distributable reserves” on its statutory balance ~~sheet.~~sheet in accordance with UK laws. Therefore, Noble-UK is not permitted to pay dividends out of share capital, which includes share premiums. The ~~resumption of the~~ payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, contractual restrictions and other factors deemed relevant by our Board of Directors.

~~Share Repurchases~~In April 2018, our shareholders approved, at our Annual General Meeting, a proposal to allow our Board of Directors to increase our share capital through the issuance of up to 82.2 million ordinary shares (at current nominal value of $0.01 per share).

During the three months ended March 31, 2018 no shares were repurchased.

Credit ~~Facility and Senior Unsecured Notes~~Facilities

2015 Credit Facility ~~and Commercial Paper Program~~

~~We currently have~~At December 31, 2017, we had a five-year $2.4 billion senior unsecured credit facility that matures in January ~~2020. The credit facility provides~~2020 and is guaranteed by our indirect, wholly-owned subsidiaries, Noble Holding (U.S.) LLC (“NHUS”) and Noble Holding International Limited (“NHIL”) (the “2015 Credit Facility”). At December 31, 2017, the 2015 Credit Facility also provided us with the ability to issue up to ~~$500~~$500.0 million in letters of credit.

On December 19, 2017, we entered into the First Amendment and Consent and Successor Agent Agreement (the “Amendment”) amending the 2015 Credit Facility. On January 3, 2018, the Amendment to the 2015 Credit Facility became fully effective. The ~~issuance~~Amendment caused, among other things, a reduction in the aggregate principal amount of ~~letters~~commitments under the 2015 Credit Facility to $300.0 million and the termination of the 2015 Credit Facility's letter of credit ~~under~~sub-facility. The maturity of the ~~facility reduces~~2015 Credit Facility remains January 2020. As a result of the 2015 Credit Facility's reduction in the aggregate principal amount ~~available for borrowing.~~of commitments, we recognized a net loss of approximately $2.3 million. At March 31, ~~2017,~~2018, we had no ~~letters~~borrowings outstanding under the 2015 Credit Facility.

2017 Credit Facility

On December 21, 2017, Noble Cayman Limited, a Cayman Islands company and a wholly-owned indirect subsidiary of Noble-Cayman (“NCL”); Noble International Finance Company, a Cayman Islands company and a wholly-owned indirect subsidiary of Noble-Cayman (“NIFCO”); and Noble Holding UK Limited, a company incorporated under the laws of England and Wales and a wholly-owned direct subsidiary of Noble-UK (“NHUK”), as parent guarantor, entered into a new senior unsecured credit agreement (the “2017 Credit Facility” and, together with the 2015 Credit Facility, the “Credit Facilities”). The maximum aggregate amount of commitments under the 2017 Credit Facility of approximately $1.5 billion became available in January 2018 upon satisfaction of certain conditions, including the effectiveness of the commitment reduction under the 2015 Credit Facility. Borrowings under the 2017 Credit Facility are subject to certain conditions precedent, including that there be no unused commitments to advance loans under the 2015 Credit Facility. The 2017 Credit Facility provides for a letter of credit ~~issued under~~sub-facility currently in the ~~facility.~~

~~Throughout the term of the credit facility, we pay a facility fee on the daily unused~~ amount of $15.0 million, with the ~~underlying commitment which ranges from 0.1 percent~~ability to ~~0.35 percent depending on our debt ratings.~~increase such amount up to $500.0 million. Borrowings may be used for working capital and other general corporate purposes. The 2017 Credit Facility will mature in January 2023. At March 31, ~~2017, based on our debt ratings on that date, the facility fee was 0.35 percent. At March 31, 2017,~~2018, we had no borrowings outstanding or letters of credit ~~issued. In addition,~~issued under the 2017 Credit Facility.

Both of our ~~credit facility has~~Credit Facilities have provisions which vary the applicable interest rates for borrowings based upon our debt ratings. We also pay a facility fee under the 2015 Credit Facility on the full commitments thereunder (used or unused) and a commitment fee under the 2017 Credit Facility on the daily unused amount of the underlying commitments, in each case which varies depending on our credit ratings. At March 31, ~~2017,~~2018, the interest ~~rate~~rates in effect isunder our Credit Facilities are the highest permitted interest ~~rate~~rates under ~~the credit facility.~~

Debt Issuances

Notes in an amount not to exceed the net cash proceeds of certain equity offerings at a redemption price equal to approximately 108% of their aggregate principal amount. Further, the 2026 Notes may be redeemed in whole at par as a result of changes in tax law requiring us to withhold taxes from payments on the 2026 Notes. On or after February 1, 2021, we may redeem all or any portion of the 2026 Notes at various redemption prices set forth in the indenture.

Senior Notes Interest Rate Adjustments

During 2016 and 2017, we experienced ~~several~~ debt rating downgrades by Moody’s Investors Service and S&P Global Ratings, which reduced our debt ratings significantly below investment grade. As a result of these downgrades, we experienced interest rate increases during 2016 and 2017 on our Senior Notes due 2018 (the “2018 Notes”), our Senior Notes due 2025 (the “2025 Notes”) and our Senior Notes due 2045 (the “ 2045 Notes”), all of which are subject to provisions ~~which~~that vary the applicable interest rates ifbased on our debt rating. On October 18, 2017, S&P Global Ratings further reduced our debt rating, ~~falls below investment grade, with continued adjustments up~~which increased the interest rates on the 2025 Notes and the 2045 Notes to ~~a contractually-defined~~7.95% and 8.95%, respectively, in April 2018. These senior notes have reached the contractually defined maximum interest rate ~~increase~~ set for each rating ~~agency. Effective March 2017, the interest rates on our Senior Notes due 2018 increased to 5.75%~~agency and ~~effective April 1, 2017, the interest rates on our Senior Notes due 2025 and 2045 increased to 7.70% and 8.70%, respectively, as a result of the most recent debt rating downgrade. On April 28, 2017, Moody’s Investors Service reduced our debt rating. However, there was~~ no further ~~increase in the interest rates on these Senior Notes because we have reached the contractually-defined maximum~~ interest rate increase ~~in respect of Moody’s Investors Service downgrades.~~will occur. The interest rates on these ~~Senior Notes~~senior notes may be ~~further increased if our debt ratings were to be downgraded further by S&P Global Ratings (up to a maximum of an additional 25 basis points) or~~ decreased if our debt ratings were to be raised by either rating agency above specified levels.

Debt Tender Offers and Repayments

In March 2018, we repaid the remaining aggregate principal amount of $126.6 million of the 2018 Notes at maturity using cash on hand.

In March 2017, we repaid ~~our maturing $300~~the aggregate principal amount of $300.0 million ~~2.50%~~of the Senior Notes due 2017 at maturity using cash on hand.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the potential for loss due to a change in the value of a financial instrument as a result of fluctuations in interest rates, currency exchange rates or equity prices, as further described below.

Interest Rate Risk

We are subject to market risk exposure related to changes in interest rates on borrowings under ~~the credit facility.~~our Credit Facilities. Interest on borrowings under ~~the credit facility~~our Credit Facilities is at an agreed upon percentage point spread over LIBOR, or a base rate stated in the ~~agreement.~~agreements. At March 31, ~~2017,~~2018, we had no borrowings outstanding under our ~~credit facility.~~Credit Facilities.

During 2016 we terminated our commercial paper program which had allowed us to issue up to $2.4 billion in unsecured commercial paper notes. This termination does not reduce the capacity under our credit facility.

~~During 2016,~~and 2017, we experienced ~~several~~ debt rating downgrades by Moody’s Investors Service and S&P Global Ratings, which reduced our debt ratings significantly below investment grade. As a result of these downgrades, we experienced interest rate increases during 2016 and 2017 on ~~our Senior~~the 2018 Notes, ~~due 2018,~~ 2025 Notes and 2045 Notes, all of which are subject to provisions ~~which~~that vary the applicable interest rates ifbased on our debt rating. On October 18, 2017, S&P Global Ratings further reduced our debt rating, ~~falls below investment grade, with continued adjustments up~~which increased the interest rates on the 2025 Notes and the 2045 Notes to ~~a contractually-defined~~7.95% and 8.95%, respectively, beginning in April 2018. These senior notes have reached the contractually defined maximum interest rate ~~increase~~ set for each rating ~~agency. Effective March 2017, the interest rates on our Senior Notes due 2018 increased to 5.75%~~agency and effective April 1, 2017, the interest rates on our Senior Notes due 2025 and 2045 increased to 7.70% and 8.70%, respectively, as a result of the most recent debt rating downgrade. On April 28, 2017, Moody’s Investors Service reduced our debt rating. However, there was no further ~~increase in the interest rates on these Senior Notes because we have reached the contractually-defined maximum~~ interest rate increase will occur.

Our other outstanding senior notes, including the 2024 Notes issued in ~~respect of Moody’s Investors Service downgrades. The~~December 2016 and the 2026 Notes issued in January 2018, do not contain provisions varying applicable interest rates ~~on these Senior Notes may be further increased if~~based upon our debt ratings were to be downgraded further by S&P Global Ratings (up to a maximum of an additional 25 basis points) or decreased if our debt ratings were to be raised by either rating agency above specified levels.credit ratings.

We maintain certain debt instruments at a fixed rate whose fair value will fluctuate based on changes in market expectations for interest rates and perceptions of our credit risk. The fair value of our total debt was ~~$3.6~~$3.3 billion and ~~$3.8~~$3.4 billion at March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, respectively. The decrease in the fair value of debt ~~primarily~~ relates to a reduction in total principal amount outstanding due to our debt repayments during the ~~repayment of our maturing $300 million 2.50% Senior Notes, which matured in March 2017,~~period, partially offset ~~with~~by our debt issuance and changes in market expectations for interest rates and perceptions of our credit risk.

Foreign Currency Risk

Although we are a UK company, we define foreign currency as any non-U.S. denominated currency. Our functional currency is ~~primarily~~ the U.S. ~~Dollar, which is consistent with the oil and gas industry.~~Dollar. However, outside the United States, a portion of our expenses are incurred in local currencies. Therefore, when the U.S. Dollar weakens (strengthens) in relation to the currencies of the countries in which we operate, our expenses reported in U.S. Dollars will increase (decrease).

We are exposed to risks on future cash flows to the extent that local currency expenses exceed revenues denominated in local currency that are other than the functional currency. To help manage this potential risk, we periodically enter into derivative instruments to manage our exposure to fluctuations in currency exchange rates, and we may conduct hedging activities in future periods to mitigate such exposure. These contracts are primarily accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Condensed Consolidated Balance Sheet and in “Accumulated other comprehensive ~~loss”~~income (loss)” (“~~AOCL”~~AOCI”). Amounts recorded in ~~AOCL~~AOCI are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of the hedged item is recorded directly to earnings. We have documented policies and procedures to monitor and control the use of derivative instruments. We do not engage in derivative transactions for speculative or trading purposes, nor are we a party to leveraged derivatives.

Several of our ~~regions,~~regional shorebases, including our ~~operations in the~~ North Sea operations, have a significant amount of their cash operating expenses payable in local currencies. To limit the potential risk of currency fluctuations, we periodically enter into forward contracts, which settle monthly in the operations’ respective local currencies. All of these contracts ~~have~~had a maturity of less than 12 months. ~~The~~

forward contract settlements in the remainder of 2017 represent approximately 70 percent of these forecasted local currency requirements. The notional amount of the forward contracts outstanding, expressed in U.S. dollars, was approximately $25 million at March 31, 2017. Total unrealized losses related to these forward contracts were approximately $0.1 million as of March 31, 2017 and were recorded as part of AOCL. A 10 percent change in the exchange rate for the local currencies would change the fair value of these forward contracts by approximately $3 million.

Market Risk

We have a U.S. noncontributory defined benefit pension plan that covers certain salaried employees and a U.S. noncontributory defined benefit pension plan that covers certain hourly employees, whose initial date of employment is prior to August 1, 2004 (collectively referred to as our “qualified U.S. plans”). These plans are governed by the Noble Drilling Employees’ Retirement Trust. The benefits from these plans are based primarily on years of service and, for the salaried plan, employees’ compensation near retirement. These plans are designed to qualify under the Employee Retirement Income Security Act of 1974 (“ERISA”), and our funding policy is consistent with funding requirements of ERISA and other applicable laws and regulations. We make cash contributions, or utilize credits available to us, for the qualified U.S. plans when required. The benefit amount that can be covered by the qualified U.S. plans is limited under ERISA and the Internal Revenue Code (“IRC”) of 1986. Therefore, we maintain an unfunded, nonqualified excess benefit plan designed to maintain benefits for specified employees at the formula level in the qualified salary U.S. plan. We refer to the qualified U.S. plans and the excess benefit plan collectively as the “U.S. plans.”

In addition to the U.S. plans, each of Noble Drilling (Land Support) Limited and Noble Resources Limited, both indirect, wholly-owned subsidiaries of Noble-UK, maintains a pension plan that covers all of its salaried, non-union employees, whose most recent date of employment is prior to April 1, 2014 (collectively referred to as our “non-U.S. plans”). Benefits are based on credited service and employees’ compensation, as defined by the plans.

Changes in market asset values related to the pension plans noted above could have a material impact upon our Condensed Consolidated Statement of Comprehensive Income (Loss) and could result in material cash expenditures in future periods.

Item 4. Controls and Procedures

Peakes, Senior Vice President and Chief Financial Officer Noble-UK, have evaluated the disclosure controls and procedures of Noble-UK as of the end of the period covered by this report. On the basis of this evaluation, ~~Mr. Williams~~Ms. Robertson and Mr. Peakes have concluded that Noble-UK’s disclosure controls and procedures were effective as of March 31, ~~2017.~~2018.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Information regarding legal proceedings is ~~set forth~~presented in ~~Notes 6~~“Note 14— Commitments and 14Contingencies,” to our condensed consolidated financial statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q and is incorporated herein by reference.

Item 1A. Risk Factors

There are numerous factors that affect our business and results of operations, many of which are beyond our control. In addition to the ~~risk factors set forth below and the~~ other information ~~set forth~~presented in this quarterly report, you should carefully read and consider ~~"Item~~“Item 1A. Risk ~~Factors"~~Factors” in Part I and ~~"Item~~“Item 7. Management's Discussion and Analysis of Financial Condition and Results of ~~Operations"~~Operations” in Part II of our annual report on Form 10-K for the year ended December 31, ~~2016,~~2017, which contains descriptions of significant risks that might cause our actual results of operations in future periods to differ materially from those currently anticipated or expected.

Paragon Offshore plc has formed a litigation trust as part of its bankruptcy proceedings and it will likely pursue fraudulent conveyance claims against us. In addition, Paragon Offshore may seek to reject in the bankruptcy proceedings certain separation agreements entered into with us, in which case we could be responsible for those liabilities for which we would have otherwise sought indemnification under the separation agreements.

In August 2014, we completed the separation and spin-off of a majority of our standard specification offshore drilling business (the “Spin-off”) through a pro rata distribution of all of the ordinary shares of our wholly-owned subsidiary, Paragon Offshore plc (“Paragon Offshore”), to the holders of our ordinary shares. In April 2016 we entered into an agreement with Paragon Offshore (subject to approval of the bankruptcy court having jurisdiction over Paragon Offshore’s bankruptcy proceeding initiated in February 2016) for a settlement with Paragon Offshore under which, we were to receive a full and unconditional release of any claims by Paragon Offshore in connection with the Spin-off (including fraudulent conveyance claims). In April 2017, Paragon Offshore filed a new bankruptcy plan (the “New Plan”). The New Plan, which was further modified in May 2017 and is subject to bankruptcy court approval, did not provide for the approval of the settlement agreement and as a result the settlement agreement was terminated. The New Plan provides for the creation and funding of a litigation trust to which Paragon Offshore would transfer its claims against us, including claims of alleged fraudulent conveyance in connection with the Spin-off. The litigation trust would be entitled to pursue those claims against us.

If the New Plan is approved and the litigation trust is established and funded, it is likely that the litigation trust would make claims against us relating to the Spin-off, including claims of alleged fraudulent conveyance. If any such claim is successful, any damages we are required to pay could have a material adverse effect on our business, financial condition and results of operations.

We entered into certain separation agreements with Paragon Offshore at the time of the Spin-off (including the master separation agreement, tax sharing agreement, transition services agreement and transition services agreement relating to our operations offshore Brazil) under which we have agreed to indemnify Paragon Offshore for certain liabilities, and Paragon Offshore has agreed to indemnify us for certain liabilities. We believe that Paragon Offshore may seek to reject some or all of these contracts in its bankruptcy proceeding. If one or more of the separation agreements are rejected, we would not be entitled to seek indemnity from Paragon Offshore under such agreement, and we could be responsible for those liabilities for which we would have otherwise sought indemnification. We could pursue claims against Paragon Offshore for such indemnity amount in the bankruptcy proceeding, but such claims would be unsecured claims and, consequently, it is uncertain whether we would be able to recover any amount of such claims. Furthermore, even if such agreements are not rejected, there can be no assurance that the indemnity from Paragon Offshore will be sufficient to protect us against the full amount of such liabilities, or that Paragon Offshore will be able or willing to fully satisfy its indemnification or performance obligations. Moreover, even if we ultimately succeed in recovering from Paragon Offshore any amounts for which we are held liable, we may be temporarily required to bear these losses. If the indemnity obligations of Paragon Offshore are extinguished as a result of the rejection of one or more of the separation agreements, or if such agreements are not rejected, but Paragon Offshore is unable or unwilling to satisfy its indemnification and other obligations, the underlying liabilities could have a material adverse effect on our business, financial condition and results of operations.

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

Under UK law, the Company is only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by shareholders. As of the date of this report, no such plan has been approved and during the three months ended March 31, ~~2017,~~2018 there were no repurchases by Noble-UK of its shares.
