In certain places in this Annual Report on Form 10-K, the company may refer to reports published by third parties that purport to describe trends or developments in energy production and drilling and exploration activity. The company does so for the convenience of its investors and potential investors and in an effort to provide information available in the market that will lead to a better understanding of the market environment in which the company operates. The company specifically disclaims any responsibility for the accuracy and completeness of such information and undertakes no obligation to update such information.

This section highlights information that is discussed in more detail in the remainder of the document. We use the terms “Tidewater,” the “company,” “we,” “us” and “our” to refer to Tidewater Inc. and its consolidated subsidiaries.

Tidewater Inc., a Delaware corporation that is a listed company on the New York Stock Exchange under the symbol “TDW”, provides offshore service vessels and marine support services to the global offshore energy industry through the operation of a diversified fleet of marine service vessels. The company was incorporated in 1956 and conducts its operations through wholly-owned United States (U.S.) and international subsidiaries, as well as through joint ventures in which Tidewater has either majority or occasionally non-controlling interests (generally where required to satisfy local ownership or local content requirements). Unless otherwise required by the context, the term “company” as used herein refers to Tidewater Inc. and its consolidated subsidiaries.

The company’s vessels and associated vessel services provide support for all phases of offshore exploration, field development and production. These services include towing of, and anchor handling for, mobile offshore drilling units; transporting supplies and personnel necessary to sustain drilling, workover and production activities; offshore construction, remotely operated vehicle (ROV) operations, and seismic and subsea support; and a variety of specialized services such as pipe and cable laying.

The company has one of the broadest geographic operating footprints in the offshore energy industry with operations in most of the world’s significant offshore crude oil and natural gas exploration and production offshore regions. Our global operating footprint allows us to react quickly to changing local market conditions and to be responsive to the changing requirements of the many customers with which we believe we have strong relationships. The company is also one of the most experienced international operators in the offshore energy industry with over 50 years of international experience.

The company’s offshore support vessel fleet includes vessels that are operated under joint ventures, as well as vessels that have been stacked or withdrawn from service. At March 31, 2017, the company owned or chartered (under sale-leaseback agreements) 260 vessels (excluding eight joint venture vessels, but including 111 stacked vessels) and eight ROVs available to serve the global energy industry. Please refer to Note (1) of Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for additional information regarding our stacked vessels.

Our revenues, net earnings and cash flows from operations are largely dependent upon the activity level of our offshore support vessel fleet. As is the case with other energy service companies, our business activity is largely dependent on the level of crude oil and natural gas and exploration, field development and production activity by our customers. Our customers’ business activity, in turn, is dependent on crude oil and natural gas prices, which fluctuate depending on expected future levels of supply and demand for crude oil and natural gas, and on estimates of the cost to find, develop and produce reserves.

The lower commodity prices from mid-2014, which persisted through 2017, resulted in reduced offshore exploration and development spending by our customers and reduced revenue and cash flows for the company, which compromised our ability to remain in compliance with certain financial covenants set forth in agreements governing our indebtedness. Prior to the end of fiscal 2016, and while the company was in compliance with its debt agreements, the company borrowed $600 million to provide adequate liquidity to weather the industry downturn. At March 31, 2017, we had $2.04 billion of debt ($2.03 billion, net of deferred debt issue costs of $6.4 million) consisting of (i) $900 million in borrowings under the Credit Agreement (as defined below), which consists of a fully drawn $600 million revolving credit facility and a $300 million term loan facility; (ii) $500 million in principal amount of 2013 Notes (as defined below); (iii) $165 million in principal amount of 2011 Notes (as defined below); (iv) $382.5 million in principal amount of 2010 Notes (as defined below); and (v) approximately $92 million of U.S. dollar-equivalent (“USD”) debt under the Troms Credit Agreement (as defined below), which consists of four tranches of unsecured debt. For additional information, see “Indebtedness” under “Liquidity, Capital Resources and Other Matters in Part II, Item 7 of this Annual Report on Form 10-K.

In response to the significant and sustained decline in commodity prices and resulting decline in the (i) utilization of our offshore support vessels, (ii) average day rates received, and (iii) vessel revenue, in fiscal 2016 and fiscal 2017, we focused on managing our balance sheet to preserve liquidity by taking certain steps, including reducing capital expenditures, terminating and/or renegotiating various contracts, and reducing our workforce and discretionary expenditures. We implemented a number of significant cost reduction measures to mitigate the effects of significantly lower vessel revenue and, given the currently challenging offshore support vessel market and business outlook, took other steps to improve our financial position and liquidity, including (i) the January 2016 suspension of our common stock dividend, (ii) the March 2016 $600 million draw on the Tidewater Credit Facility, and (iii) the renegotiation or termination of vessel construction contracts in order to reduce capital expenditures, which increased current and projected liquidity by in excess of $200 million.

Despite efforts to reduce spending, we determined that with our current capital structure, we were not positioned to withstand the ongoing and precipitous decline in oil and gas prices and the corresponding decline in revenues and cash flows. We concluded that a reduction in our long-term debt and cash interest obligations was required to improve our financial position and flexibility. Additionally, we retained financial and legal advisors, to assist us in analyzing and considering financial, transactional and strategic alternatives. As such, we engaged Weil, Gotshal & Manges LLP (“Weil”), as our restructuring counsel and Lazard Frères & Co. LLC (“Lazard”), as our investment banker and financial advisor, to assist us in developing and implementing a comprehensive restructuring plan.

At June 30, 2016, we failed to meet a 3.0x minimum interest coverage ratio covenant contained in the Credit Agreement, the Troms Credit Agreement, and the 2013 Notes Purchase Agreement (each as defined below) (collectively, the “Funded Debt Agreements”), which resulted in covenant noncompliance that would have allowed the respective lenders and/or the noteholders to declare us to be in default under each of the Funded Debt Agreements, and accelerate the indebtedness thereunder. In addition, our projected covenant non-compliance resulted in the inclusion in the report provided by our independent registered public accounting firm that accompanied our audited consolidated financial statements for the fiscal year ended March 31, 2016 (the “Audit Opinion”) of an explanatory paragraph regarding our ability to continue as a going concern. Our inability to receive an Audit Opinion without modification was a separate event of default under the Credit Agreement that would have allowed the lenders to accelerate the indebtedness thereunder.

To avoid an acceleration of indebtedness under the Funded Debt Agreements (and potentially the other Senior Unsecured Notes) we negotiated and obtained limited waivers from the necessary lenders and noteholders to extend the waiver of the audit opinion requirement and/or waive the minimum interest coverage ratio requirement until August 14, 2016 and subsequent, further extensions until September 18, 2016, October 21, 2016, November 11, 2016, January 27, 2017, March 3, 2017, and March 27, 2017.

Since January 2016, we have been actively engaged in discussions and negotiations regarding restructuring alternatives with (i) a steering committee comprised of certain Tidewater Lenders (as defined below) (the “Bank Lender Steering Committee”), (ii) the Troms Lenders (as defined below), and (iii) an unofficial committee of certain unaffiliated holders of the 2013 Notes (the “Unofficial 2013 Noteholder Committee”). Since December 2016, such discussions and negotiations have focused on a restructuring through a consensual prepackaged plan pursuant to chapter 11 of the U.S. Bankruptcy Code that would be supported by a substantial percentage of our lenders and the noteholders. When the March 27, 2017 waiver expired on April 7, 2017 in accordance with its terms, our negotiations with the Bank Lender Steering Committee and the Unofficial Noteholder Committee regarding the terms of the restructuring were substantially complete. By early May, the Debtors (as defined below), the Bank Lender Steering Committee and the Unofficial Noteholder Committee reached an agreement in principle regarding the terms, and processes to document, the Restructuring embodied in the Prepackaged Plan through the RSA (as defined below). The RSA is an agreement pursuant to which the lenders agree to support the Prepackaged Plan. The Debtors were also able to reach an agreement in principle with the Troms Lenders regarding an amendment of the Troms Credit Agreement to be executed in conjunction with the Prepackaged Plan.

Restructuring Support Agreement. Prior to filing the Bankruptcy Petitions (as defined below), on May 11, 2017, the Debtors (as defined below) entered into a Restructuring Support Agreement (the “RSA”) with certain of its creditors (collectively, the “Consenting Creditors”), specifically: (i) lenders holding approximately 60% of the outstanding principal amount of the loans under the company’s Fourth Amended and Restated Revolving Credit Agreement, dated as of June 21, 2013 (the “Credit Agreement”), between the company as borrower, each of the guarantors named therein, Bank of America, N.A., as administrative agent and the lenders party thereto (the “Consenting Tidewater Lenders”) and (ii) holders of approximately 99% of the aggregate outstanding principal amount of Tidewater’s (a) 3.90% Senior Notes, 2010-Series B due December 30, 2017, 3.95% Senior Notes, 2010-Series C due December 30, 2017, 4.12% Senior Notes, 2010-Series D due December 30, 2018, 4.17% Senior Notes, 2010-Series E due December 30, 2018, 4.33% Senior Notes,

2010-Series F due December 30, 2019, 4.51% Senior Notes, 2010-Series G due December 30, 2020, 4.56% Senior Notes, 2010-Series H due December 30, 2020, and 4.61% Senior Notes, 2010-Series I due December 30, 2022 (collectively, the “2010 Notes”), (b) 4.06% Senior Notes, Series 2011-A due March 31, 2019, 4.64% Senior Notes, Series 2011-B due June 30, 2021, and 4.54% Senior Notes, Series 2011-C due June 30, 2021 (collectively, the “2011 Notes”), and (c) 4.26% Senior Notes, Series 2013-A due November 16, 2020, 5.01% Senior Notes, Series 2013-B due November 15, 2023, and 5.16% Senior Notes, Series 2013-C due November 17, 2025 (collectively, the “2013 Notes,” and together with the 2010 Notes and the 2011 Notes, the “Notes”) (such holders, the “Consenting Noteholders”) to support a restructuring on the terms of the Prepackaged Plan. On May 12, 2017, the Debtors commenced the solicitation of votes on the Prepackaged Plan.

Troms Forbearance Agreement and Amendment to the Troms Facility Agreement. As previously disclosed, on May 25, 2012, the Debtors, as guarantors, entered into a Term Loan Facility Agreement as amended and restated (the “Troms Facility Agreement”) with Troms Offshore Supply AS, as borrower (the “Troms Borrower”), Eksportkreditt Norge AS and Kommunal Landspensjonskasse Gjensidig Forsikringsselskap as lenders (the “Troms Lenders”), and certain bank guarantors party thereto (together with the Troms Lenders, the “Troms Finance Parties”). On May 11, 2017, the Debtors, the Troms Borrower, the Troms Finance Parties, the Additional Obligors (as defined herein) and Garantiinstituttet for Eksportkreditt and DNB Capital LLC as additional lenders (the “Additional Lenders”), entered into an Amendment and Restatement Agreement No. 4 (the “Fourth Amendment”), pursuant to which, among other things, (a) the Additional Lenders agreed to make available to the Troms Borrower a new term loan for up to $5,068,863, (b) Troms Offshore Fleet Holding AS, Troms Offshore Fleet 1 AS, Troms Offshore Fleet 2 AS, Troms Offshore Fleet 3 AS, Troms Offshore Fleet 4 AS, and JB Holding Company BV, each an indirect, wholly-owned foreign subsidiary of the company, agreed to serve as additional obligors of the obligations thereunder (collectively, the “Additional Obligors”), and (c) the Debtors, the Troms Borrower, the Additional Obligors, the Troms Finance Parties, and the Additional Lenders agreed to amend and restate the Troms Facility Agreement (the “Amended and Restated Troms Facility Agreement”). The Fourth Amendment will become effective on the Effective Date (as defined below).

On May 11, 2017, the Debtors also entered into a Forbearance Agreement (the “Forbearance Agreement”) with the Troms Borrower, the Additional Lenders, DNB Bank ASA, New York Branch, as agent on behalf of the Troms Finance Parties, and the Norwegian Export Credit Guarantee Agency, as bank guarantor, which Forbearance Agreement relates to the Troms Facility Agreement. Pursuant to the Forbearance Agreement, among other provisions, the Troms Finance Parties have agreed that during the Forbearance Period (as defined below), subject to certain conditions precedent and continuing conditions, they will not enforce, or otherwise take any action to direct enforcement of, any of the rights and remedies available to the Finance Parties under the Troms Facility Agreement or otherwise, including, without limitation, any action to accelerate, or join in any request for acceleration of, the Troms Facility Agreement due to the company commencing voluntary cases under chapter 11 of the Bankruptcy Code as contemplated by the RSA and the continued existence of certain specified events of default. The Forbearance Period began on May 11, 2017 and ends on the earliest of (i) August 30, 2017, (ii) the occurrence of any event of default under the Troms Facility Agreement, other than certain specified events of default, and (iii) the termination of the RSA as a result of the occurrence of any (a) Creditor Termination Event (as defined in the RSA), (b) Tidewater Termination Event (as defined in the RSA), or (c) other termination of the RSA under its terms.

On May 17, 2017 (the “Petition Date”), the company and certain subsidiaries, Cajun Acquisitions, LLC, Gulf Fleet Supply Vessels, L.L.C., Hilliard Oil & Gas, Inc., Java Boat Corporation, Pan Marine International Dutch Holdings, L.L.C., Point Marine, L.L.C., Quality Shipyards, L.L.C., S.O.P., Inc., Tidewater Corporate Services, L.L.C., Tidewater GOM, Inc., Tidewater Marine, L.L.C., Tidewater Marine Alaska, Inc., Tidewater Marine Fleet, L.L.C., Tidewater Marine Hulls, L.L.C., Tidewater Marine International Dutch Holdings, L.L.C., Tidewater Marine Sakhalin, L.L.C., Tidewater Marine Ships, L.L.C., Tidewater Marine Vessels, L.L.C., Tidewater Marine Western, Inc., Tidewater Mexico Holding, L.L.C., Tidewater Subsea, L.L.C., Tidewater Subsea ROV, L.L.C., Tidewater Venture, Inc., Twenty Grand (Brazil), L.L.C., Twenty Grand Marine Service, L.L.C., and Zapata Gulf Marine L.L.C., (together with the company, the “Debtors”) filed voluntary petitions for reorganization (the “Bankruptcy Petitions”) in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court") seeking relief under the provisions of chapter 11 of title 11 of the United States Code (the "Bankruptcy Code"). On May 19, 2017, the Bankruptcy Court set a combined hearing to consider approval of the Debtors’ disclosure statement and confirmation of the Prepackaged Plan for June 28, 2017. If the Prepackaged Plan is approved by the Bankruptcy Court within the time frame we currently expect, the Prepackaged Plan will likely become effective in July 2017, at which point or shortly thereafter the Debtors would emerge from bankruptcy, however, there can be no assurance that the effectiveness of the Prepackaged Plan will occur on such date, or at all.

As of the Petition Date, we had outstanding, unsecured prepetition funded debt obligations totaling approximately $2.04 billion. We also had certain obligations arising under the Sale Leaseback Agreements, pursuant to which the Debtors charter certain vessels owned by third parties. Additionally, as of the Petition Date, we had $23.7 million of accrued interest payable on our Credit Facility and Notes. With the filing of the petition in bankruptcy, all of the debt represented by the Credit Agreement, the Notes, and the Troms Facility Agreement accelerated, but the enforcement of the lenders and noteholders rights thereunder have been stayed by the bankruptcy proceeding.

In connection with the restructuring contemplated by the Prepackaged Plan, the Debtors have identified certain cost savings opportunities, including the elimination of burdensome obligations under certain sale leaseback agreements (the “Sale Leaseback Agreements”), pursuant to which the Debtors charter certain vessels owned by third parties (the “Sale Leaseback Parties”). On the Petition Date, the Debtors filed a motion seeking to reject such agreements (the rejection damage claims related thereto, the “Sale Leaseback Claims”). Pursuant an order by the Bankruptcy Court approving a stipulation with the Sale Leaseback Parties, the Bankruptcy Court approved the rejection of the Sale Leaseback Agreements, the reserve for the Sale Leaseback Claims until they are resolved in the amount of approximately $324 million, and the temporary allowance of the disputed Sale Leaseback Claims for purposes of voting on the Prepackaged Plan.

During the bankruptcy proceedings, the Debtors are operating as "debtors-in-possession" in accordance with applicable provisions of the Bankruptcy Code. The Bankruptcy Court granted a number of first day motions filed by the Debtors, allowing the company to operate its business in the ordinary course throughout the bankruptcy process. The first day motions authorized, among other things, the company to pay prepetition employee wages and benefits without interruption, maintain its insurance programs, utilize its current cash management system, and pay undisputed prepetition obligations owed to its vendors and trade creditors in the ordinary course of business. Subject to certain exceptions under the Bankruptcy Code, the commencement of the Debtors’ chapter 11 cases automatically stayed most judicial or administrative actions against the Debtors and their property to, among other things, recover, or collect a pre-petition claim.

The Prepackaged Plan is subject to the approval of the Bankruptcy Court and anticipates, among other things, that on the effective date of the Prepackaged Plan (the “Effective Date”):

The company and the Sale Leaseback Parties did not reach agreement with respect to the amount of the Sale Leaseback Claims. Accordingly, on the Effective Date, a portion of the above consideration in cash, Jones Act Warrants, and New Secured Notes in an amount that the company believes represents the maximum possible distributions owing on account of the Sale Leaseback Claims will be withheld from the cash, Jones Act Warrants, and New Secured Notes distributed to allowed General Unsecured Claims on account of such disputed Sale Leaseback Claims until they are resolved. To the extent the Sale Leaseback Claims are resolved for less than the amount withheld, the remainder will be distributed to holders of allowed General Unsecured Claims pro rata.

Assuming implementation of the Prepackaged Plan, the company expects that it will eliminate approximately $1.6 billion in principal amount of outstanding debt. In addition, taking into account the rejection of the Sale-Leaseback Agreements discussed above, the company estimates that interest and operating lease expenses, collectively, will be reduced by approximately $73 million annually. Combined vessel operating lease expense and interest and debt costs, net was $108.8 million for fiscal year 2017.

For additional information on the bankruptcy proceedings, the RSA, the Prepackaged Plan and the Troms Forbearance Agreement and Amendment to the Troms Facility Agreement, see Part II. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

The company’s worldwide headquarters and principal executive offices are located at 601 Poydras Street, Suite 1500, New Orleans, Louisiana 70130, and its telephone number is (504) 568-1010. The company’s U.S. marine operations are based in Amelia, Louisiana and Houston, Texas. We conduct our international operations through facilities and offices located in over 30 countries. Our principal international offices and/or warehouse facilities, most of which are leased, are located in Rio de Janeiro and Macae, Brazil; Ciudad Del Carmen, Mexico; Port of Spain, Trinidad; Aberdeen, Scotland; Amsterdam, Holland; Cairo, Egypt; Luanda and Cabinda, Angola; Lagos and Onne Port, Nigeria; Douala, Cameroon; Singapore; Shenzhen, China; Al Khobar, Kingdom of Saudi Arabia; Dubai, United Arab Emirates; and Oslo and Tromso, Norway. The company’s operations generally do not require highly specialized facilities, and suitable facilities are generally available on a leased basis as required.

We manage and measure our business performance in four distinct operating segments that are based on the geographical location of our operations: Americas, Asia/Pacific, Middle East, and Africa/Europe. At the beginning of fiscal year 2017, our operations in the Mediterranean Sea (based in Egypt) were transitioned from the previously disclosed Middle East/North Africa operations and included with the previously disclosed Sub-Saharan Africa/Europe operations as a result of management realignment. As such, we now disclose these new segments as Middle East and Africa/Europe, respectively. Our Americas and Asia/Pacific segments were not affected by this change. This new segment alignment is consistent with our chief operating decision maker’s review of operating results for the purposes of allocating resources and assessing performance. Our Americas segment includes the activities of our North American operations, which include operations in the U.S. Gulf of Mexico (GOM) and U.S. and Canadian coastal waters of the Pacific and Atlantic oceans, as well as operations offshore Mexico, Trinidad and Brazil. The Asia/Pacific segment includes our Australian and Southeast Asian and Western Pacific operations. Our Middle East segment includes our operations in the Arabian Gulf and offshore India. Lastly, our Africa/Europe segment includes operations conducted along the East and West Coasts of Africa as well as operations in and around the Caspian Sea, the Mediterranean and Red Seas, the Black Sea, the North Sea and certain other arctic/cold water markets.

Our principal customers in each of these business segments are large, international oil and natural gas exploration, field development and production companies (IOCs); select independent exploration and production (E&P) companies; foreign government-owned or government-controlled organizations and other related companies that explore for, develop and produce oil and natural gas (NOCs); drilling contractors; and other companies that provide various services to the offshore energy industry, including but not limited to, offshore construction companies, diving companies and well stimulation companies.

The company’s vessels are dispersed throughout the major offshore crude oil and natural gas exploration, field development and production areas of the world. Although the company considers, among other things, mobilization costs and the availability of suitable vessels in its fleet deployment decisions, and cabotage rules in certain countries occasionally restrict the ability of the company to move vessels between markets, the company’s diverse, mobile asset base and the wide geographic distribution of its vessels generally enable the company to respond relatively quickly to changing market conditions and customer requirements.

Revenues in each of our segments are derived primarily from vessel time charter or similar contracts that are generally from three months to four years in duration as determined by customer requirements, and, to a lesser extent, from vessel time charter contracts on a “spot” basis, which is a short-term (one day to three months) agreement to provide offshore marine services to a customer for a specific short-term job. The base rate of hire for a term contract is generally a fixed rate, though some charter arrangements allow the company to recover specific additional costs.

In each of our segments, and depending on vessel capabilities and availability, our vessels operate in the shallow, intermediate and deepwater offshore markets. The deepwater offshore market has been an increasingly important sector of the offshore crude oil and natural gas markets due to technological developments that have made deepwater exploration and development feasible and, if the commodity pricing environment improves, deepwater exploration and development could return to being a source of potential long-term growth for the company. Deepwater oil and gas development typically involves significant capital investment and multi-year development plans. Such projects are generally underwritten by the participating exploration, field development and production companies using relatively conservative crude oil and natural gas pricing assumptions. Although these projects are generally less susceptible to short-term fluctuations in the price of crude oil and natural gas, deepwater exploration and development projects can be costly relative to other onshore and offshore exploration and development. As a result, the sustained low levels of crude oil prices has caused, and may continue to cause, many E&P companies to restrain their level of capital expenditures in regards to deepwater projects.

As of March 31, 2017, there were approximately 50 deepwater offshore rigs under construction; however, there is uncertainty as to how many of those rigs, most of which are expected to enter service within the next two years, will increase the offshore working rig fleet (which was approximately 420 rigs at March 31, 2017, down approximately 80 rigs over the past 12 months) and how many of those rigs will replace older, less productive drilling units or be unable to secure work at all. The dayrates and the overall utilization of the worldwide deepwater offshore supply vessel fleet, which is also expected to increase in size, will, at least in part, depend upon whether there is an overall net growth in the number of working deepwater rigs.

Please refer to Item 7 of this Annual Report on Form 10-K for a more detailed discussion of the company’s segments, including the macroeconomic environment in which we operate. In addition, please refer to Note (15) of Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for segment, geographical data and major customer information.

The company’s fleet is deployed in the major global offshore oil and gas areas of the world. The principal areas of the company’s operations include the U.S. GOM, the Arabian Gulf, the Mediterranean Sea and areas offshore Australia, Brazil, India, Malaysia, Mexico, Norway, the United Kingdom, Thailand, Trinidad, and West and East Africa.

Our Global Vessel Fleet and Vessel Construction, Acquisition and Replacement Program

Since fiscal 2000, the company has been engaged in a vessel construction, acquisition and replacement program, with the intent of being able to operate in nearly all major oil and gas producing regions of the world by replacing older vessels in the company’s fleet with larger, more technologically sophisticated vessels. During that period, the company purchased and/or constructed 290 vessels at a total cost of approximately $5 billion (including 41 vessels at a cost of $331.1 million that were subsequently sold in transactions other than sale/lease transactions). To date, the company has generally funded its vessel programs from its operating cash flows, together with funds provided by four private debt placements of senior unsecured notes and borrowings under bank credit facilities, proceeds from the disposition of (generally older) vessels, and various vessel sale-leaseback arrangements.

The company operates the largest number of new offshore support vessels among its competitors in the industry. The company will continue to carefully consider whether future proposed investments and transactions have the appropriate risk/return-on-investment profile.

The average age of the company’s 260 owned or chartered vessels (excluding joint-venture vessels) at March 31, 2017 is approximately 9.8 years. Of the company’s 260 vessels, 104 are deepwater platform supply vessels (PSVs) or deepwater anchor handling towing supply (AHTS) vessels, and 109 vessels are non-deepwater towing-supply vessels, which include both smaller PSVs and smaller AHTS vessels that primarily serve the jackup drilling market. Included within our “other” vessel class are 47 vessels which are primarily crew boats and offshore tugs.

At March 31, 2017, the company had commitments to build two vessels at two different shipyards at a total cost, including contract costs and other incidental costs, of approximately $110 million. At March 31, 2017, the company had invested approximately $77 million in progress payments towards the construction of the two vessels, and the remaining expenditures necessary to complete construction was estimated at $33 million. The two vessels under construction at March 31, 2017 are deepwater PSVs, between approximately 5,150 and 5,900 deadweight tons of cargo carrying capacity. In April 2017, the company was paid $5.3 million in connection with a novation agreement, pursuant to which the company assigned its construction contract for the one internationally built vessel to a third party thus relieving the company of future payments of $27.2 million related to this vessel. Remaining commitments are $5.8 million after giving effect to the novation agreement.

The company disposed of 725 vessels during the fiscal 2000 to fiscal 2017 period. Most of the vessels were sold at prices that exceeded such vessels’ carrying values at the time of disposition by the company. In the aggregate, proceeds from, and pre-tax gains on, vessel dispositions during this period approximated $800 million and $330 million, respectively.

Further discussions of our vessel construction, acquisition and replacement program, including the various settlement agreements with certain international shipyards related to the construction of vessels and our capital commitments, scheduled delivery dates and recent vessel sales are disclosed in the “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 and Note (12) of Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

The “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 in this Annual Report on Form 10-K also contains a table comparing the actual March 31, 2017 vessel count and the average number of vessels by class and geographic distribution during the three years ended March 31, 2017, 2016 and 2015.

Our vessels routinely move from one geographic region and reporting segment to another, and from one operating area to another operating area within the geographic regions and reporting segments. We disclose our vessel statistical information, including revenue, utilization and average day rates, by vessel class. Listed below are our three major vessel classes along with a description of the type of vessels categorized in each vessel class and the services the respective vessels typically perform. Tables comparing the average size of the company’s vessel fleet by class and geographic distribution for the last three fiscal years are included in Item 7 of this Annual Report on Form 10-K.

Deepwater vessels, in the aggregate, are currently the company’s largest contributor to consolidated vessel revenue and vessel operating margin. Included in this vessel class are large PSVs (typically greater than 230-feet and/or with greater than 2,800 tons in dead weight cargo carrying capacity) and large, higher-horsepower AHTS vessels (generally greater than 10,000 horsepower). These vessels are generally chartered to customers for use in transporting supplies and equipment from shore bases to deepwater and intermediate water depth offshore drilling rigs and production platforms and for otherwise supporting intermediate and deepwater drilling, production, construction and maintenance operations. Deepwater PSVs generally have large cargo carrying capacities, both below deck (liquid mud tanks and dry bulk tanks) and above deck. Deepwater AHTS vessels are equipped to tow drilling rigs and other marine equipment, as well as to set anchors for the positioning and mooring of drilling rigs that generally do not have dynamic positioning capabilities. Many of our deepwater PSVs and AHTS vessels are outfitted with dynamic positioning capabilities, which allow the vessel to maintain an absolute or relative position when mooring to an offshore installation, rig or another vessel is deemed unsafe, impractical or undesirable. Many of our deepwater vessels also have oil recovery, firefighting, standby rescue and/or other specialized equipment. Our customers have high standards in regards to safety and other operational competencies and capabilities, in part to meet the more stringent regulatory standards, especially in the wake of the 2010 Deepwater Horizon incident.

Our deepwater class of vessel also includes specialty vessels that can support offshore well stimulation, construction work, subsea services and/or serve as remote accommodation facilities. These vessels are generally available for routine supply and towing services, but these vessels are also outfitted, and primarily intended, for specialty services. For example, these vessels can be equipped with a variety of lifting and deployment systems, including large capacity cranes, winches or reel systems. Included in the specialty vessel category is the company’s one multi-purpose platform supply vessel (MPSV). Our MPSV is approximately 311 feet in length, has a 100-ton active heave compensating crane, a moonpool and a helideck and is designed for subsea service and light construction support activities. This vessel is significantly larger in size, more versatile, and more specialized than the PSVs discussed above. The MPSV typically commands a higher day rate because the vessel has more capabilities, and because the vessel has a higher construction cost and higher operating costs.

This is currently the company’s largest fleet class by number of vessels. Included in this class are non-deepwater AHTS vessels with horsepower below 10,000 BHP, and non-deepwater PSVs that are generally less than 230 feet. The vessels in this class perform the same respective functions and services as deepwater AHTS vessels and deepwater PSVs except towing-supply vessels are generally chartered to customers for use in intermediate and shallow waters.

The company’s “Other” vessels include crew boats, utility vessels and offshore tugs. Crew boats and utility vessels are chartered to customers for use in transporting personnel and supplies from shore bases to offshore drilling rigs, platforms and other installations. These vessels are also often equipped for oil field security missions in markets where piracy, kidnapping or other potential violence presents a concern. Offshore tugs are used to tow floating drilling rigs and barges; to assist in the docking of tankers; and to assist pipe laying, cable laying and construction barges.

Revenues from vessel operations were derived from the following classes of vessels in the following percentages:

Historically, the company’s subsea services were composed primarily of seismic and subsea vessel support. During fiscal 2014 the company expanded its subsea services capabilities by hiring a dedicated group of employees with substantial ROV and subsea expertise and by purchasing six work-class ROVs. Two additional higher specification work-class ROVs were added to the company’s fleet in fiscal 2015. Each ROV is capable of being deployed and redeployed worldwide on a variety of vessels and platforms, and we began ROV deployment and operations in fiscal 2015. Our expanded subsea services capabilities include services and engineering solutions in all phases of the life of a subsea well, including exploration, construction and installation, and maintenance, repair and inspection. Our equipment and subsea professionals can support subsea operations in water depths of up to 13,000 feet. In connection with the purchase of ROVs, the company has developed a proprietary operations management system customized for the operation of ROVs. While we are generally curtailing additional investment in subsea services and other growth initiatives given reduced offshore activity levels, further expansion of our subsea services business, if undertaken, may include organic growth through commissioning the construction of additional ROVs or acquisitions of recently built ROVs and/or other ROV owners and operators.

The company’s operations are dependent upon the levels of activity in offshore crude oil and natural gas exploration, field development and production throughout the world, which is affected by trends in global crude oil and natural gas pricing, including expectations of future commodity pricing, which is ultimately influenced by the supply and demand relationship for these natural resources. The activity levels of our customers are also influenced by the cost of exploring for and producing crude oil and natural gas, which can be affected by environmental regulations, technological advances that affect energy production and consumption, significant weather conditions, the ability of our customers to raise capital, and local and international economic and political environments, including government mandated moratoriums.

The recent trend in crude oil prices and the current pricing outlook could lead to increased exploration, development and production activity as current prices for WTI and ICE Brent are approaching the range which some surveys have indicated that, if sustainable, E&P companies would begin to increase spending. However, a recovery in onshore exploration, development and production activity and spending, and in North American onshore activity and spending in particular, has already begun and is expected to continue to precede a recovery in offshore activity and spending, much of which takes place in the international markets. These same analysts also expect that a further decrease in offshore spending is likely during calendar year 2017 and that any improvements in offshore E&P activity would likely not occur until calendar year 2018, the timing of which is generally consistent with the trend of the projected global working offshore rig count according to recent IHS-Petrodata reports. A discussion of current market conditions and trends appears under “Macroeconomic Environment and Outlook” in Item 7 of this Annual Report on Form 10-K.

The company’s principal customers are IOCs; select independent E&P companies; NOCs; drilling contractors; and other companies that provide various services to the offshore energy industry, including but not limited to, offshore construction companies, diving companies and well stimulation companies.

Our primary source of revenue is derived from time charter contracts on our vessels on a rate per day of service basis; therefore, vessel revenues are recognized on a daily basis throughout the contract period. As noted above, these time charter contracts are generally either on a term or “spot” basis. There are no material differences in the cost structure of the company’s contracts based on whether the contracts are spot or term because the operating costs for an active vessel are generally the same without regard to the length of a contract.

The following table discloses our customers that accounted for 10% or more of total revenues during any of our last three fiscal years:

While it is normal for our customer base to change over time as our vessel time charter contracts turn over, the unexpected loss of any of these significant customers could, at least in the short term, have a material adverse effect on the company’s vessel utilization and its results of operations. Our five largest customers in aggregate accounted for approximately 53% of our fiscal 2017 total revenues, while the ten largest customers in aggregate accounted for approximately 75% of the company’s fiscal 2017 total revenues.

The principal competitive factors for the offshore vessel service industry are the suitability and availability of vessels and related equipment, price and quality of service. In addition, the ability to demonstrate a strong safety record and attract and retain qualified and skilled personnel are also important competitive factors. The company has numerous competitors in all areas in which it operates around the world, and the business environment in all of these markets is highly competitive.

The company’s diverse, mobile asset base and the wide geographic distribution of its assets generally enable the company to respond relatively quickly to changes in market conditions and to provide a broad range of vessel services to its customers around the world. We believe that size, age, diversity and geographic distribution of a vessel operator’s fleet, economies of scale and experience level in the many areas of the world are competitive advantages in our industry.

Increases in worldwide vessel capacity generally have the effect of lowering charter rates, particularly when there are lower levels of exploration, field development and production activity as has been the case since late calendar 2014 when oil prices began to trend lower.

According to IHS-Petrodata, the global offshore support vessel market had approximately 335 new-build offshore support vessels (deepwater PSVs, deepwater AHTS vessels and towing-supply vessels only) either under construction (290 vessels), or on order as of March 2017. The vessels under construction are scheduled to be delivered into the worldwide offshore vessel market primarily over the next 12 months. The current worldwide fleet of these classes of vessels is estimated at approximately 3,510 vessels, of which we estimate that a significant portion are stacked or are not being actively marketed by the vessels’ owners. The worldwide offshore marine vessel industry, however, also has a large number of aged vessels, including approximately 620 vessels, or 18%, of the worldwide offshore fleet, that are at least 25 years old and nearing or exceeding original expectations of their estimated economic lives. These older vessels, of which we estimate the majority are already stacked or not actively marketed by the vessels’ owners, could potentially be removed from the market in the near future if the cost of extending the vessels’ lives is not economical, especially in light of recent market conditions.

Excluding the 620 vessels that are at least 25 years old from the overall population, the company estimates that the number of offshore support vessels under construction (290 vessels) represents approximately 10% of the remaining worldwide fleet of approximately 2,890 offshore support vessels.

Although the future attrition rate of the older offshore support vessels cannot be determined with certainty, the company believes that the retirement and/or sale to owners outside of the oil and gas market of a vast majority of these aged vessels (a majority of which the company believes have already been stacked or are not being actively marketed to oil and gas development-focused customers by the vessels’ owners) could mitigate the potential negative effects on vessel utilization

and vessel pricing of (i) additional offshore support vessel supply resulting from the delivery of additional new-build vessels and (ii) reduced demand for offshore support vessels resulting from reduced offshore spending by E&P companies. Similarly, the cancellation or deferral of delivery of some portion of the 290 offshore support vessels that are under construction according to IHS-Petrodata would also mitigate the potential negative effects on vessel utilization and vessel pricing of reduced demand for offshore support vessels resulting from reduced offshore spending by E&P companies.

In addition, we and other offshore support vessel owners have selectively stacked more recently constructed vessels as a result of the significant reduction in our customers’ offshore oil and gas-related activity and the resulting more challenging offshore support vessel market that has existed since late calendar 2014. Should market conditions continue to remain depressed, the stacking or underutilization of recently constructed vessels by the offshore supply vessel industry will likely continue.

We operate in many challenging operating environments around the world that present varying degrees of political, social, economic and other uncertainties. We operate in markets where risks of expropriation, confiscation or nationalization of our vessels or other assets, terrorism, piracy, civil unrest, changing foreign currency exchange rates, and changing political conditions may adversely affect our operations. Although the company takes what it believes to be prudent measures to safeguard its property, personnel and financial condition against these risks, it cannot eliminate entirely the foregoing risks, though the wide geographic dispersal of the company’s vessels helps reduce the overall potential impact of these risks.

In addition, immigration, customs, tax and other regulations (and administrative and judicial interpretations thereof) can have a material impact on our ability to work in certain countries and on our operating costs.

In some international operating environments, local customs or laws may require or make it advisable that the company form joint ventures with local owners or use local agents. The company is dedicated to carrying out its international operations in compliance with the rules and regulations of the Office of Foreign Assets Control (OFAC), the Trading with the Enemy Act, the Foreign Corrupt Practices Act (FCPA), and other applicable laws and regulations. The company has adopted policies and procedures to mitigate the risks of violating these rules and regulations.

The company has previously disclosed the significant financial and operational challenges that it confronts with respect to its substantial operations in Angola, as well as steps that the company has taken to address or mitigate those risks. Most of the company’s attention has been focused in three areas: reducing the net receivable balance due the company from Sonatide, its Angolan joint venture with Sonangol, for vessel services; reducing the foreign currency risk created by virtue of provisions of Angolan law that require that payment for a significant portion of the services provided by Sonatide be paid in Angolan kwanza; and optimizing opportunities, consistent with Angolan law, for services provided by the company be paid for directly in U.S. dollars. These challenges, and the company’s efforts to respond, continue.

Amounts due from Sonatide (Due from affiliate in the consolidated balance sheets) at March 31, 2017 and March 31, 2016 of approximately $263 million and $339 million, respectively, represent cash received by Sonatide from customers and due to the company, amounts due from customers that are expected to be remitted to the company through Sonatide and costs incurred by the company on behalf of Sonatide. Approximately $56 million of the balance at March 31, 2017 represents invoiced but unpaid vessel revenue related to services performed by the company through the Sonatide joint venture. Remaining amounts due to the company from Sonatide are, in part, supported by (i) approximately $90 million of cash (primarily denominated in Angolan kwanzas) held by Sonatide that is pending conversion into U.S. dollars and the subsequent expatriation of such funds and (ii) approximately $133 million of amounts due from the company to Sonatide, including $34.7 million in commissions payable by the company to Sonatide with the balance related to costs incurred by Sonatide on behalf of the company.

For the year ended March 31, 2017, the company collected (primarily through Sonatide) approximately $114 million from its Angolan operations. Of the $114 million collected, approximately $101 million were U.S. dollars received by Sonatide on behalf of the company or U.S. dollars received directly by the company from customers. The balance of $13 million collected reflects Sonatide’s conversion of Angolan kwanza into U.S. dollars and the subsequent expatriation of the dollars and payment to the company. The company also reduced the net due from affiliate and due to affiliate balances by approximately $88 million during the year ended March 31, 2017 through netting transactions based on an agreement with the joint venture.

Amounts due to Sonatide (Due to affiliate in the consolidated balance sheets) at March 31, 2017 and March 31, 2016 of approximately $133 million and $188 million, respectively, represents amounts due to Sonatide for commissions payable and other costs paid by Sonatide on behalf of the company.

The company believes that the process for converting Angolan kwanzas continues to function, but is challenged because of the tight U.S. dollar liquidity situation that continues in Angola. Sonatide continues to press the commercial banks with which it has relationships to increase the amount of U.S. dollars that are made available to Sonatide.

For the year ended March 31, 2017, the company’s Angolan operations generated vessel revenues of approximately $127 million, or 22%, of its consolidated vessel revenue, from an average of approximately 58 company-owned vessels that are marketed through the Sonatide joint venture (20 of which were stacked on average during the year ended March 31, 2017), and, for the year ended March 31, 2016, generated vessel revenues of approximately $213 million, or 22%, of consolidated vessel revenue, from an average of approximately 65 company-owned vessels (eight of which were stacked on average during the year ended March 31, 2016).

Sonatide owns seven vessels (three of which are currently stacked) and certain other assets, in addition to earning commission income from company-owned vessels marketed through the Sonatide joint venture (owned 49% by the company). As of March 31, 2017 and March 31, 2016, the carrying value of the company’s investment in the Sonatide joint venture, which is included in ”Investments in, at equity, and advances to unconsolidated companies,” was approximately $45 million and $37 million, respectively.

Management continues to explore ways to profitably participate in the Angolan market while looking for opportunities to reduce the overall level of exposure to the increased risks that the company believes currently characterize the Angolan market. Included among mitigating measures taken by the company to address these risks is the redeployment of vessels from time to time to other markets. Redeployment of vessels to and from Angola during the year ended March 31, 2017 and year ended March 31, 2016 has resulted in a net 22 and 23 vessels transferred out of Angola, respectively.

The International Labour Organization's Maritime Labour Convention, 2006 (the "Convention") mandates globally, among other things, seafarer living and working conditions (accommodations, wages, conditions of employment, health and other benefits) aboard ships that are engaged in commercial activities. Since its initial entry into force on August 20, 2013, 81 countries have now ratified the Convention.

The company continues to prioritize certification of its vessels to Convention requirements based on the dates of enforcement by countries in which the company has operations, performs maintenance and repairs at shipyards, or may make port calls during ocean voyages. Once obtained, vessel certifications are maintained, regardless of the area of operation. Additionally, where possible, the company continues to work with its operationally identified flag states to seek substantial equivalencies to comparable national and industry laws that meet the intent of the Convention and allow the company to standardize operational protocols among its fleet of vessels that work in various areas around the world.

The company is subject to various United States federal, state and local statutes and regulations governing the operation and maintenance of its vessels. The company’s U.S. flagged vessels are subject to the jurisdiction of the United States Coast Guard, the United States Customs and Border Protection, and the United States Maritime Administration. The company is also subject to international laws and conventions and the laws of international jurisdictions where the company and its offshore vessels operate.

Under the citizenship provisions of the Merchant Marine Act of 1920 and the Shipping Act, 1916, as amended, the company would not be permitted to engage in the U.S. coastwise trade if more than 25% of the company’s outstanding

stock were owned by non-U.S. citizens. For a company engaged in the U.S. coastwise trade to be deemed a U.S. citizen: (i) the company must be organized under the laws of the United States or of a state, territory or possession thereof, (ii) each of the chief executive officer and the chairman of the board of directors of such corporation must be a U.S. citizen, (iii) no more than a minority of the number of directors of such corporation necessary to constitute a quorum for the transaction of business can be non-U.S. citizens and (iv) at least 75% of the interest in such company must be owned by U.S. citizens. The company has a dual stock certificate system to protect against non-U.S. citizens owning more than 25% of its common stock. In addition, the company’s charter provides the company with certain remedies with respect to any transfer or purported transfer of shares of the company’s common stock that would result in the ownership by non-U.S. citizens of more than 24% of its common stock. Based on information supplied to the company by its transfer agent, approximately 8% of the company’s outstanding common stock was owned by non-U.S. citizens as of March 31, 2017.

The company’s vessel operations in the U.S. GOM are considered to be coastwise trade. United States law requires that vessels engaged in the U.S. coastwise trade must be built in the U.S. and registered under U.S flag. In addition, once a U.S. built vessel is registered under a non-U.S. flag, it cannot thereafter engage in U.S. coastwise trade. Therefore, the company’s non-U.S. flagged vessels must operate outside of the U.S. coastwise trade zone. Of the total 260 vessels owned or operated by the company at March 31, 2017, 236 vessels were registered under flags other than the United States and 24 vessels were registered under the U.S. flag.

All of the company’s offshore vessels are subject to either United States or international safety and classification standards or sometimes both. U.S. flag deepwater PSVs, deepwater AHTS vessels, towing-supply vessels, and crewboats are required to undergo periodic inspections twice within every five year period pursuant to U.S. Coast Guard regulations. Vessels registered under flags other than the United States are subject to similar regulations and are governed by the laws of the applicable international jurisdictions and the rules and requirements of various classification societies, such as the American Bureau of Shipping.

The company is in compliance with the International Ship and Port Facility Security (ISPS) Code, an amendment to the Safety of Life at Sea (SOLAS) Convention (1974/1988), and further mandated in the Maritime Transportation and Security Act of 2002 to align United States regulations with those of SOLAS and the ISPS Code. Under the ISPS Code, the company performs worldwide security assessments, risk analyses, and develops vessel and required port facility security plans to enhance safe and secure vessel and facility operations. Additionally, the company has developed security annexes for those U.S. flag vessels that transit or work in waters designated as high risk by the United States Coast Guard pursuant to the latest revision of Marsec Directive 104-6.

During the ordinary course of business, the company’s operations are subject to a wide variety of environmental laws and regulations that govern the discharge of oil and pollutants into navigable waters. Violations of these laws may result in civil and criminal penalties, fines, injunctions and other sanctions. Compliance with the existing governmental regulations that have been enacted or adopted regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment has not had, nor is expected to have, a material effect on the company. Environmental laws and regulations are subject to change, however, and may impose increasingly strict requirements, and, as such, the company cannot estimate the ultimate cost of complying with such potential changes to environmental laws and regulations.

The company is also involved in various legal proceedings that relate to asbestos and other environmental matters. The amount of ultimate liability, if any, with respect to these proceedings is not expected to have a material adverse effect on the company’s financial position, results of operations, or cash flows. The company is proactive in establishing policies and operating procedures for safeguarding the environment against any hazardous materials aboard its vessels and at shore-based locations.

Whenever possible, hazardous materials are maintained or transferred in confined areas in an attempt to ensure containment, if accidents were to occur. In addition, the company has established operating policies that are intended to increase awareness of actions that may harm the environment.

We are dedicated to ensuring the safety of our operations for our employees, our customers and any personnel associated with our operations. Tidewater’s principal operations occur in offshore waters where the workplace environment presents many safety challenges. Management communicates frequently with company personnel to promote safety and instill safe work habits through the use of company media directed at, and regular training of, both our seamen and shore-based personnel. Personnel and resources are dedicated to ensure safe operations and regulatory compliance. Our Director of Health, Safety, Environment and Security (HSES) Management is involved in numerous proactive efforts to prevent accidents and injuries from occurring. The HSES Director also reviews all incidents that occur throughout the company, focusing on lessons that can be learned from such incidents and opportunities to incorporate such lessons into the company’s on-going safety-related training. In addition, the company employs safety personnel in every operating region to be responsible for administering the company’s safety programs and fostering the company’s safety culture. The company’s position is that each of its employees is a safety supervisor, who has the authority and the obligation to stop any operation that they deem to be unsafe.

The operation of any marine vessel involves an inherent risk of marine losses (including physical damage to the vessel) attributable to adverse sea and weather conditions, mechanical failure, and collisions. In addition, the nature of our operations exposes the company to the potential risks of damage to and loss of drilling rigs and production facilities, hostile activities attributable to war, sabotage, piracy and terrorism, as well as business interruption due to political action or inaction, including nationalization of assets by foreign governments. Any such event may lead to a reduction in revenues or increased costs. The company’s vessels are generally insured for their estimated market value against damage or loss, including war, acts of terrorism, and pollution risks, but the company does not directly or fully insure for business interruption. The company also carries workers’ compensation, maritime employer’s liability, director and officer liability, general liability (including third party pollution) and other insurance customary in the industry.

The company seeks to secure appropriate insurance coverage at competitive rates, in part, by maintaining self-insurance up to certain individual and aggregate loss limits. The company carefully monitors claims and participates actively in claims estimates and adjustments. Estimated costs of self-insured claims, which include estimates for incurred but unreported claims, are accrued as liabilities on our balance sheet.

The continued threat of terrorist activity and other acts of war or hostility have significantly increased the risk of political, economic and social instability in some of the geographic areas in which the company operates. It is possible that further acts of terrorism may be directed against the United States domestically or abroad, and such acts of terrorism could be directed against properties and personnel of U.S. headquartered companies such as ours. The resulting economic, political and social uncertainties, including the potential for future terrorist acts and war, could cause the premiums charged for the insurance coverage to increase. The company currently maintains war risk coverage on its entire fleet.

Management believes that the company’s insurance coverage is adequate. The company has not experienced a loss in excess of insurance policy limits; however, there is no assurance that the company’s liability coverage will be adequate to cover potential claims that may arise. While the company believes that it should be able to maintain adequate insurance in the future at rates considered commercially acceptable, it cannot guarantee that such insurance will continue to be available at commercially acceptable rates given the markets in which the company operates.

The company’s global vessel fleet generally has its highest utilization rates in the warmer months when the weather is more favorable for offshore exploration, field development and construction work. Hurricanes, cyclones, the monsoon season, and other severe weather can negatively or positively impact vessel operations. In particular, the company’s U.S. GOM operations can be impacted by the Atlantic hurricane season from the months of June through November, when offshore exploration, field development and construction work tends to slow or halt in an effort to mitigate potential losses and damage that may occur to the offshore oil and gas infrastructure should a hurricane enter the area. However, demand for offshore marine vessels typically increases in the U.S. GOM in connection with repair and remediation work that follows any hurricane damage to offshore crude oil and natural gas infrastructure. The company’s vessels that operate offshore India in Southeast Asia and in the Western Pacific are impacted by the monsoon season, which moves across the region from November to April. Vessels that operate in the North Sea can be impacted by a seasonal slowdown in the winter months, generally from November to March. Vessels that operate in Australia are impacted by cyclone season from November to April. Customers in this region, where possible, plan business activities around the cyclone season;

however, Australia generally has high trade winds even during the non-cyclone season and, as such, the impact of the cyclone season on any operations in Australia is not significant. Although hurricanes, cyclones, monsoons and other severe weather can have a seasonal impact on operations, the company’s business volume is more dependent on crude oil and natural gas pricing, global supply of crude oil and natural gas, and demand for the company’s offshore support vessel and other services than on any seasonal variation.

As of March 31, 2017, the company had approximately 5,510 employees worldwide, a reduction of approximately 1,040 from March 31, 2016, as a result of our efforts to reduce costs due to the downturn in the offshore oil services industry. The company is not a party to any union contract in the United States but through several subsidiaries is a party to union agreements covering local nationals in several countries other than the United States. In the past, the company has been the subject of a union organizing campaign for the U.S. GOM employees by maritime labor unions. These union organizing efforts have abated, although the threat has not been completely eliminated. If the employees in the U.S. GOM were to unionize, the company’s flexibility in managing industry changes in the domestic market could be adversely affected.

We operate globally in challenging and highly competitive markets and thus our business is subject to a variety of risks. Listed below are some of the more critical or unique risk factors that we have identified as affecting or potentially affecting the company and the offshore marine service industry which could cause our actual results to differ materially from those anticipated, projected or assumed in the forward-looking statements. You should consider all risks when evaluating any of our forward-looking statements. The effect of any one risk factor or a combination of several risk factors could materially affect our results of operations, financial condition and cash flows and the accuracy of any forward-looking statements made in this Annual Report on Form 10-K.

We will be subject to the risks and uncertainties associated with the chapter 11 proceedings.

On May 17, 2017, the company, along with certain of its domestic subsidiaries, filed voluntary petitions seeking relief under chapter 11 of the Bankruptcy Code. The chapter 11 bankruptcy proceedings do not include our international subsidiaries.

Our operations and ability to develop and execute our business plan, our financial condition, our liquidity, and our continuation as a going concern, are subject to the risks and uncertainties associated with our bankruptcy. These risks include the following:

As of March 31, 2017, we had $2.04 billion of debt ($2.03 billion, net of deferred debt issue costs of $6.4 million). While we anticipate $1.6 billion of our indebtedness will be discharged if and when the company emerges from bankruptcy, there is no assurance that the effectiveness of the Prepackaged Plan will occur in July 2017 as expected, or at all.

Delays in our chapter 11 proceedings increase the risks of our being unable to reorganize our business and emerge from bankruptcy and increase our costs associated with the bankruptcy process.

These risks and uncertainties could affect our business and operations in various ways. For example, negative events or publicity associated with our chapter 11 proceedings could adversely affect our relationships with our suppliers, service providers, customers, employees, and other third parties, which in turn could adversely affect our operations and financial condition. Also, pursuant to the Bankruptcy Code, we need the prior approval of the Bankruptcy Court for transactions outside the ordinary course of business, which may limit our ability to respond timely to unanticipated or unusual events or

take advantage of certain opportunities. We also need Bankruptcy Court confirmation of the Prepackaged Plan. Because of the risks and uncertainties associated with our chapter 11 proceedings, we cannot accurately predict or quantify the ultimate impact that events that occur during our chapter 11 proceedings will have on our business, financial condition and results of operations or that may be inconsistent with our plans.

The proposed treatment of our common stockholders under the terms of the Prepackaged Plan may be challenged by the company’s creditors that have not agreed to support the Prepackaged Plan, and the Bankruptcy Court may alter the Prepackaged Plan in a manner that treats our common stockholders less favorably.

The Prepackaged Plan provides, among other things, that upon our emergence from our chapter 11 cases, shares of our existing common stock will be canceled and the holders of our existing common stock will receive thereafter, in the aggregate, five percent of the pro forma common equity in reorganized Tidewater Inc. (subject to dilution by management incentive plan and the exercise of warrants to existing stockholders under the Prepackaged Plan) plus warrants to acquire up to an additional 15% of common stock of reorganized Tidewater Inc. if certain market capitalization benchmarks are achieved. The Prepackaged Plan may not be confirmed by the Bankruptcy Court, in which case, the chance that the existing shareholders will receive little or no distribution in our chapter 11 proceedings would increase. Accordingly, any trading in shares of our common stock during the pendency of the chapter 11 proceedings is highly speculative.

We may be subject to claims that will not be discharged in our chapter 11 proceedings, which could have a material adverse effect on our financial condition and results of operations.

The Bankruptcy Code provides that the confirmation of a chapter 11 plan of reorganization discharges a debtor from substantially all debts arising prior to confirmation. With few exceptions, all claims that arose prior to confirmation of the plan of reorganization (i) would be subject to compromise and/or treatment under the plan of reorganization and (ii) would be discharged in accordance with the Bankruptcy Code and the terms of the plan of reorganization. Any claims not ultimately discharged through a chapter 11 plan of reorganization could be asserted against the reorganized entities and may have an adverse effect on our financial condition and results of operations on a post-reorganization basis.

Upon emergence from bankruptcy, our historical financial information may not be comparable to our future financial performance.

Our capital structure will be significantly altered under the Prepackaged Plan. Under fresh start reporting rules that would apply to us upon the effective date of the Prepackaged Plan (or any alternative plan of reorganization), our assets and liabilities would be adjusted to fair values and our accumulated deficit would be eliminated. In such case, our financial condition and results of operations following our emergence from our chapter 11 cases would not be comparable to the financial condition and results of operations reflected in our historical financial statements.

The pursuit of the RSA has consumed, and the chapter 11 proceedings will continue to consume, a substantial portion of the time and attention of our management, which may have an adverse effect on our business and results of operations, and we may face increased levels of employee attrition.

Although the RSA and the Prepackaged Plan have been structured to minimize the length of our chapter 11 proceedings, it is impossible to predict with certainty the duration of the bankruptcy proceeding. The chapter 11 proceedings will involve additional expense and our management will be required to devote substantial time and effort focusing on the proceedings. This diversion of attention may have a material adverse effect on the conduct of our business, and, as a result, our financial condition and results of operations, particularly if the chapter 11 proceedings are protracted.

During the pendency of the chapter 11 proceedings, our employees will face considerable distraction and uncertainty, and we may experience increased levels of employee attrition. A loss of key personnel or material erosion of employee morale could have a material adverse effect on our ability to effectively, efficiently and safely conduct our business, and could impair our ability to execute our strategy and implement operational initiatives, thereby having a material adverse effect on our financial condition and results of operations.

Upon emergence from bankruptcy, the composition of our board of directors will change significantly.

Under the Prepackaged Plan, the composition of our board of directors will change significantly. Upon emergence, the board will be made up of seven directors, six of whom will be designated by the Consenting Creditors who are parties to the RSA, with the only continuing director being our current Chief Executive Officer. Our new directors are likely to have

different backgrounds, experiences and perspectives from those individuals who previously served on the board and who may, individually and collectively, have different views on the issues that will determine the future of the company. As a result, the future strategy and plans of the company may differ materially from those of the past.

The Prepackaged Plan and any other plan of reorganization that we may implement will be based in large part upon assumptions, projections and analyses developed by us. If these assumptions, projections and analyses prove to be incorrect in any material respect, the Prepackaged Plan may not be successfully implemented.

The Prepackaged Plan and any other plan of reorganization that we may implement have been based in important part on assumptions and analyses based on our experience and perception of historical trends, current conditions and expected future developments, as well as other factors that we have considered appropriate under the circumstances. Whether actual future results and developments will be consistent with our expectations and assumptions depends on a number of factors, including but not limited to (i) our ability to change substantially our capital structure; (ii) our ability to maintain customers’ confidence in our viability as a continuing entity and to attract and retain sufficient business from them; (iii) our ability to retain key employees; and (iv) the overall strength and stability of general economic conditions of the financial and oil and gas industries, both in the U.S. and in global markets. The failure of any of these factors could materially adversely affect the successful reorganization of our businesses.

In addition, the Prepackaged Plan and any other plan of reorganization will rely upon financial projections, including with respect to revenues, EBITDA, capital expenditures, debt service and cash flow. Financial forecasts are necessarily speculative, and it is likely that one or more of the assumptions and estimates that are the basis of these financial forecasts will not be accurate. In our case, the forecasts are more speculative than normal, because they are based on an expectation that our balance sheet will be substantially deleveraged. Accordingly, our actual financial condition and results of operations may differ, perhaps materially, from what we have anticipated. Consequently, there can be no assurance that the results or developments contemplated by any plan of reorganization we may implement will occur or, even if they do occur, that they will have the anticipated effects on us and our subsidiaries or our business or operations. The failure of any such results or developments to materialize as anticipated could materially adversely affect the successful execution of any plan of reorganization.

There can be no assurance that the Prepackaged Plan (or any other plan of reorganization) will be approved by the Court, so we urge caution with respect to existing and future investments in our securities.

The success of any reorganization will depend on approval by the Court and the willingness of existing unsecured creditors, including our noteholders and lenders under our credit agreement, to agree to the exchange or modification of their interests as outlined in the Prepackaged Plan, and there can be no guarantee of success with respect to the Prepackaged Plan or any other plan of reorganization. We might receive official objections to confirmation of the Prepackaged Plan from the various stakeholders in the chapter 11 proceedings, including any official committees appointed. We cannot predict the impact that any objection might have on the Prepackaged Plan or on a Court's decision to confirm the Prepackaged Plan. Any objection may cause us to devote significant resources in response which could materially and adversely affect our business, financial condition and results of operations.

If the Prepackaged Plan is not confirmed by the Court, it is unclear whether we would be able to reorganize our business and what, if any, distributions holders of claims against us, including holders of our secured and unsecured debt and equity, would ultimately receive with respect to their claims and interests. There can be no assurance as to whether we will successfully reorganize and emerge from chapter 11 or, if we do successfully reorganize, as to when we would emerge from chapter 11. If no plan of reorganization can be confirmed, or if the Court otherwise finds that it would be in the best interest of holders of claims and interests, the chapter 11 Cases may be converted to cases under chapter 7 of the Bankruptcy Code, pursuant to which a trustee would be appointed or elected to liquidate our assets for distribution in accordance with the priorities established by the Bankruptcy Code.

Even if a chapter 11 Plan of Reorganization is consummated, we may not be able to achieve our stated goals.

Even if the Prepackaged Plan or another chapter 11 plan of reorganization is consummated, we will continue to face a number of risks, including an extended period of a challenged climate of commodity prices or other changes in economic conditions, changes in our industry, changes in demand for oil and gas and our services and increasing expenses. Accordingly, we cannot guarantee that the Prepackaged Plan or any other chapter 11 plan of reorganization will achieve our stated goals.

Furthermore, even if our debts are reduced or discharged through the Prepackaged Plan, we may need to raise additional funds through public or private debt or equity financing or other various means to fund our business after the completion of our chapter 11 proceedings. Our access to additional financing is, and for the foreseeable future will likely continue to be, extremely limited, if it is available at all. Therefore, adequate funds may not be available when needed or may not be available on favorable terms, if they are available at all.

Transfers of our equity, or issuances of equity in connection with our chapter 11 proceedings, may impair our ability to utilize our federal income tax net operating loss carryforwards and depreciation deductions in future years.

Under U.S. federal income tax law, a corporation is generally permitted to deduct from taxable income net operating losses carried forward from prior years. We had net operating loss carryforwards of approximately $47.6 million as of March 31, 2017 and the company may generate additional net operating losses during fiscal 2018. Our ability to utilize such net operating loss carryforwards to offset future taxable income and to reduce our U.S. federal income tax liability is subject to certain requirements and restrictions. If we experience an “ownership change,” as defined in section 382 of the Internal Revenue Code, then our ability to use our pre-emergence net operating loss carryforwards and amortizable tax basis in our properties may be substantially limited, which could have a negative impact on our financial position and results of operations. Generally, there is an “ownership change” if one or more stockholders owning 5% or more of a corporation’s common stock have aggregate increases in their ownership of such stock of more than 50 percentage points over the prior three-year period. Following the implementation of a plan of reorganization, it is possible that an “ownership change” may be deemed to occur. Under section 382 of the Internal Revenue Code, absent an applicable exception, if a corporation undergoes an “ownership change,” the amount of its net operating losses that may be utilized to offset future taxable income generally is subject to an annual limitation. Even if the net operating loss carryforwards are subject to limitation under Section 382, the net operating losses can be further reduced by the amount of discharge of indebtedness arising in a chapter 11 case under Section 108 of the Internal Revenue Code. Further, future deductions for depreciation could be limited if the fair value of our assets is determined to be less than the tax basis.

We requested that the Bankruptcy Court approve restrictions on certain transfers of our stock to limit the risk of an “ownership change” prior to our restructuring in our chapter 11 proceedings. Following the implementation of our Plan, it is likely that an “ownership change” will be deemed to occur and our net operating losses will nonetheless be subject to annual limitation.

In certain instances, a chapter 11 case may be converted to a case under chapter 7 of the Bankruptcy Code.

Upon a showing of cause, the Bankruptcy Court may convert our chapter 11 case to a case under chapter 7 of the Bankruptcy Code. In such event, a chapter 7 trustee would be appointed or elected to liquidate our assets for distribution in accordance with the priorities established by the Bankruptcy Code. We believe that liquidation under chapter 7 would result in significantly smaller distributions being made to our creditors than those provided for in our Plan because of (i) the likelihood that the assets would have to be sold or otherwise disposed of in a distressed fashion in a distressed industry environment over a short period of time rather than in a controlled manner and as a going concern, (ii) additional administrative expenses involved in the appointment of a chapter 7 trustee, and (iii) additional expenses and claims, some of which would be entitled to priority, that would be generated during the liquidation and from the rejection of leases and other executory contracts in connection with a cessation of operations.

The prices for oil and gas affect the level of capital spending by our customers which in turn affects demand and pricing for our services and could negatively impact our results of operations.

Even in a more favorable commodity pricing climate, prices for crude oil and natural gas are highly volatile and extremely sensitive to the respective supply/demand relationship for crude oil and natural gas. The significant decline in crude oil and natural gas prices that began in 2014 has continued to cause many of our customers to significantly reduce drilling, completion and other production activities and related spending on our products and services through fiscal 2017. Some industry analysts expect that a further decrease in offshore spending is likely during calendar year 2017 and that any improvements in offshore E&P activity would likely not occur until calendar year 2018. In addition, the reduction in demand from our customers has resulted in an oversupply of the vessels available for service, and such oversupply has substantially reduced the prices we can charge our customers for our services.

Many factors affect the supply of and demand for crude oil and natural gas and, therefore, influence prices of these commodities, including:

The ongoing depressed level of oil and natural gas prices significantly curtailed our customers’ drilling, completion and other production activities and related spending on our services in fiscal 2017. The energy industry’s level of capital spending is substantially related to current and expected future demand for hydrocarbons and the prevailing commodity prices of crude oil and, to a lesser extent, natural gas. When commodity prices are low, or when our customers believe that they will be low in the future, our customers generally reduce their capital spending budgets for onshore and offshore drilling, exploration and field development. The continuing depressed levels of crude oil and natural gas prices has reduced significantly the energy industry’s level of capital spending and as long as current conditions persist, capital spending and demand for our services may remain similarly depressed. It is difficult to predict how long the current commodity price conditions will continue, or to what extent low commodity prices will affect our business. Because a prolonged material downturn in crude oil and natural gas prices and/or perceptions of long-term lower commodity prices can negatively impact the development plans of exploration and production companies given the long-term nature of large-scale development projects, a downturn of any such duration would likely result in a significant decline in demand for offshore support services. Declining or continuing depressed oil and natural gas prices may result in negative pressures on:

Moreover, higher commodity prices will not necessarily translate into increased demand for offshore support services or sustained higher pricing for offshore support vessel services, in part because customer demand is based on future commodity price expectations and not solely on current prices. Additionally, increased commodity demand may in the future be satisfied by land-based energy resource production and any increased demand for offshore support vessel services can be more than offset by an increased supply of offshore support vessels resulting from the construction of additional offshore support vessels.

Crude oil pricing volatility has increased in recent years as crude oil has emerged as a widely-traded financial asset class. To the extent speculative trading of crude oil causes excessive crude oil pricing volatility, our results of operations could potentially be negatively impacted if such price volatility affects spending and investment decisions of offshore exploration, development and production companies.

We participate in a capital-intensive industry. We may not be able to finance future growth of our operations or future acquisitions.

Our activities require substantial capital expenditures. If our cash flows from operating activities are not sufficient to fund capital expenditures, we would be required to further reduce these expenditures or to fund capital expenditures through debt or equity issuances or through alternative financing plans or selling assets.

Our ability to raise debt or equity capital or to refinance or restructure existing debt arrangements will depend on the condition of the capital markets and our financial condition at such time, among other things. Any limitations in our ability to finance future capital expenditures may limit our ability to respond to changes in customer preferences, technological change and other market conditions, which may diminish our competitive position within our sector.

The continued consolidation of our customer base could negatively impact the demand for our services.

Oil and natural gas companies and other energy companies and energy services companies have undergone consolidation, and additional consolidation is possible. Consolidation reduces the number of customers for our equipment, and may negatively affect exploration, development and production activity as consolidated companies focus, at least initially, on increasing efficiency and reducing costs and may delay or abandon exploration activity with less promise. Such activity could adversely affect demand for our offshore services.

The high level of competition on the offshore marine service industry could negatively impact pricing for our services.

We operate in a highly competitive industry, which could depress charter and utilization rates and adversely affect our financial performance. We compete for business with our competitors on the basis of price; reputation for quality service; quality, suitability and technical capabilities of our vessels and ROVs; availability of vessels and ROVs; safety and efficiency; cost of mobilizing vessels and ROVs from one market to a different market; and national flag preference. In addition, competition in international markets may be adversely affected by regulations requiring, among other things, local construction, flagging, ownership or control of vessels, the awarding of contracts to local contractors, the employment of local citizens and/or the purchase of supplies from local vendors.

Our results of operations, financial condition and cash flows could all be negatively impacted by the loss of a major customer.

We derive a significant amount of revenue from a relatively small number of customers. For the fiscal years ended March 31, 2017, 2016 and 2015, the five largest customers accounted for approximately 53%, 47% and 45%, respectively, of our total revenues, while the 10 largest customers accounted for approximately 75%, 69%, and 62%, respectively, of our total revenues. While it is normal for our customer base to change over time as our time charter contracts expire and are replaced, our results of operations, financial condition and cash flows could be materially adversely affected if one or more of these customers were to decide to interrupt or curtail their activities, in general, or their activities with us; terminate their contracts with us; fail to renew existing contracts; and/or refuse to award new contracts.

The rise in production of unconventional crude oil and gas resources could increase supply without a commensurate growth in demand which would negatively impact oil and gas prices which in turn could negatively impact demand for our services.

The rise in production of unconventional crude oil and gas resources in North America and the commissioning of a number of new large Liquefied Natural Gas (LNG) export facilities around the world have contributed to an over-supplied natural gas market. Production from unconventional resources has increased as drilling efficiencies have improved, lowering the costs of extraction. There has also been a buildup of crude oil inventories in the United States in part due to the increased development of unconventional crude oil resources. Prolonged increases in the worldwide supply of crude oil and natural gas, whether from conventional or unconventional sources, without a commensurate growth in demand for crude oil and natural gas will likely continue to weigh on the price of crude oil and natural gas. A prolonged period of low crude oil and natural gas prices would likely have a negative impact on development plans of exploration and production companies), which in turn, may result in a decrease in demand for offshore support vessel services.

Uncertain economic conditions may lead our customers to postpone capital spending which could negatively impact our liquidity and financial condition.

Uncertainty about future global economic market conditions makes it challenging to forecast operating results and to make decisions about future investments. The success of our business is both directly and indirectly dependent upon conditions in the global financial and credit markets that are outside of our control and difficult to predict. Uncertain economic conditions may lead our customers to postpone capital spending in response to tighter credit and reductions in our customers’ income or asset values. Similarly, when lenders and institutional investors reduce, and in some cases, cease to provide funding to corporate and other industrial borrowers, the liquidity and financial condition of our company and our customers can be adversely impacted. These factors may also adversely affect our liquidity and financial condition. Factors such as interest rates, availability of credit, inflation rates, economic uncertainty, changes in laws (including laws relating to taxation), trade barriers, commodity prices, currency exchange rates and controls, and national and international political circumstances (including wars, terrorist acts, security operations, and seaborne refugee issues) can have a material negative effect on our business, revenues and profitability.

An increase in vessel capacity without a corresponding increase in the working offshore rig count could exacerbate the industry’s currently oversupplied condition which could negatively impact pricing and demand for our services, which, in turn, could negatively impact our revenues.

Over the past decade, the combination of historically high commodity prices and technological advances resulted in significant growth in deepwater exploration, field development and production. As a result, offshore service companies, such as ours, constructed specialized offshore vessels that are capable of supporting deepwater and deep well (defined by well depth rather than water depth) projects. During this time, construction of offshore vessels increased significantly in order to meet projected requirements of customers and potential customers. Excess offshore support vessel capacity usually exerts downward pressure on charter day rates. Excess capacity can occur when newly constructed vessels enter the worldwide offshore support vessel market and also when vessels migrate between markets. A discussion about our vessel fleet and vessel construction programs appears in the “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 in this Annual Report on Form 10-K.

The offshore support vessel market has approximately 335 new-build offshore support vessels (deepwater PSVs, deepwater AHTS vessels and towing-supply vessels only) either under construction (290 vessels), on order or planned as of March 2017, which may be delivered to the worldwide offshore support vessel market primarily over the next 12 months, according to IHS-Petrodata. The current worldwide fleet of these classes of vessels is estimated at approximately 3,510 vessels, according to the same source. An increase in vessel capacity without a corresponding increase in the working offshore rig count could exacerbate the industry’s currently oversupplied condition which may have the effect of lowering charter rates and utilization rates, which, in turn, would result in lower revenues to the company.

In addition, the provisions of U.S. shipping laws restricting engagement of U.S. coastwise trade to vessels controlled by U.S. citizens may from time to time be circumvented by foreign competitors that seek to engage in trade reserved for vessels controlled by U.S. citizens and otherwise qualifying for coastwise trade. A repeal, suspension or significant modification of U.S. shipping laws, or the administrative erosion of their benefits, permitting vessels that are either foreign-flagged, foreign-built, foreign-owned, foreign-controlled or foreign-operated to engage in the U.S. coastwise trade, could also result in excess vessel capacity and increased competition, especially for our vessels that operate in North America.

We operate in various regions throughout the world and are exposed to many risks inherent in doing business in countries other than the United States.

We operate in various regions throughout the world and are exposed to many risks inherent in doing business in countries other than the United States, some of which have recently become more pronounced. Our customary risks of operating internationally include political and economic instability within the host country; possible vessel seizures or nationalization of assets and other governmental actions by the host country, including enforcement of customs, immigration or other laws that are not well developed or consistently enforced; foreign government regulations that favor or require the awarding of contracts to local competitors; an inability to recruit, retain or obtain work visas for workers of international operations; difficulties or delays in collecting customer and other accounts receivable; changing taxation policies; fluctuations in currency exchange rates; foreign currency revaluations and devaluations; restrictions on converting foreign currencies into U.S. dollars; expatriating customer and other payments made in jurisdictions outside of the United States; and import/export quotas and restrictions or other trade barriers, most of which are beyond the control of the company. See (i) the “Legal Proceedings” section of “Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 and Note (12) of Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K and (ii) “Sonatide Joint Venture” in Item 1 and Note (12) of Notes to Consolidated Financial Statements included in Item 8 in this Annual Report on Form 10-K for a discussion of our Sonatide joint venture in Angola. While we no longer operate in Venezuela, we note that we have substantial operations in Brazil, Mexico, Saudi Arabia, Angola and throughout the west coast of Africa, which generate a large portion of our revenue, where we are exposed to the risks described above.

We are also subject to acts of piracy and kidnappings that put our assets and personnel at risk. The increase in the level of these criminal or terrorist acts over the last several years has been well-publicized. As a marine services company that operates in offshore, coastal or tidal waters in challenging areas, we are particularly vulnerable to these kinds of unlawful activities. Although we take what we consider to be prudent measures to protect our personnel and assets in markets that present these risks, we have confronted these kinds of incidents in the past, and there can be no assurance we will not be subjected to them in the future.

The continued threat of terrorist activity, other acts of war or hostility and civil unrest have significantly increased the risk of political, economic and social instability in some of the geographic areas in which we operate. It is possible that further acts of terrorism or civil unrest may be directed against the United States domestically or abroad, and such acts of terrorism or civil unrest could be directed against properties and personnel of U.S. headquartered companies such as ours. To date, we have not experienced any material adverse effects on our results of operations and financial condition as a result of terrorism, political instability, civil unrest or war.

We may not be able to generate sufficient cash flow to meet our debt service and other obligations.

Our ability to make payments on our indebtedness and to fund our operations depends on our ability to generate cash in the future. This, to a large extent, is subject to conditions in the oil and natural gas industry, including commodity prices, demand for our services and the prices we are able to charge for our services, general economic and financial conditions, competition in the markets in which we operate, the impact of legislative and regulatory actions on how we conduct our business and other factors, all of which are beyond our control.

Lower levels of offshore exploration and development activity and spending by our customers globally has had a direct and significant impact on our financial performance, financial condition and financial outlook.

We review the vessels in our active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable and we also perform a review of our stacked vessels not expected to return to active service every six months, or whenever changes in circumstances indicate that the carrying amount of a vessel may not be recoverable. We have recorded impairment charges of $484.7 million, $117.3 million and $14.5 million during the years ended March 31, 2017, 2016 and 2015, respectively. In the event that offshore E&P industry conditions continue to deteriorate, or persist at current levels, the company could be subject to additional vessel impairments in future periods. An impairment loss on our property and equipment exists when the estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. Any impairment loss recognized represents the excess of the asset’s carrying value over the estimated fair value. As part of this analysis, we make assumptions and estimates regarding future market conditions. To the extent actual results do not meet our estimated assumptions we may take an impairment loss in the future. Additionally, there can be no assurance that we will not have to take additional impairment charges in the future if the currently depressed market conditions persist.

The amount of our debt and the covenants in the agreements governing our debt could negatively impact our financial condition, results of operations and business prospects.

As of March 31, 2017, we had $2.04 billion of debt ($2.03 billion, net of deferred debt issue costs of $6.4 million). Our level of indebtedness, and the covenants contained in the agreements governing our debt, could have important consequences for our operations, including:

Our long-term debt instruments are subject to affirmative and negative covenants, including financial ratios and tests, with which we must comply (including a requirement that we comply with a 3.0x minimum interest coverage covenant). These covenants include, among others, covenants that restrict our ability to take certain actions without the permission of the holders of our indebtedness, including the incurrence of debt, the granting of liens, the making of investments and the sale of assets.

On May 17, 2017, the company, along with certain of its domestic subsidiaries, filed voluntary petitions seeking relief under chapter 11 of the United States Bankruptcy Code. While we anticipate approximately $1.6 billion of indebtedness will be discharged if and when the company emerges from bankruptcy, there is no assurance that the effectiveness of the Prepackaged Plan will occur in July 2017 as expected, or at all. Please see “Reorganization and Chapter 11 Proceedings” disclosures in Business in Item 1 of this report for a discussion of the RSA, Forbearance Agreement and the Prepackaged Plan for additional information regarding the potential restructuring of our indebtedness and debt instruments.

Our ability to satisfy required financial covenants, ratios and tests in our debt agreements can be limited by events beyond our control, including continuing low commodity prices, reduced demand for our services, depressed valuations of our assets as well as prevailing economic, financial and industry conditions, and we can offer no assurance that we will be able to remain in compliance with such covenants or that the holders of our indebtedness will not seek to assert that we are not in compliance with our covenants. A breach of any of these covenants, ratios or tests could result in a default, which may result in a cross-default of other indebtedness. If we default, our lenders could declare all amounts of outstanding debt together with accrued interest, to be immediately due and payable. The results of such actions would have a significant negative impact on our results of operations, financial position and cash flows.

We may not be able to obtain debt financing if and when needed with favorable terms, if at all, which could negatively impact our financial condition.

There are a number of potential negative consequences for the energy and energy services sectors that may result if commodity prices remain depressed or decline or if E&P companies continue to de-prioritize investments in offshore exploration, development and production, including a general outflow of credit and capital from the energy and energy services sectors and/or offshore focused energy and energy service companies, further efforts by lenders to reduce their loan exposure to the energy sector, the imposition of increased lending standards for the energy and energy services sectors, higher borrowing costs and collateral requirements or a refusal to extend new credit or amend existing credit facilities in the energy and energy services sectors. These potential negative consequences may be exacerbated by the pressure exerted on financial institutions by bank regulatory agencies to respond quickly and decisively to credit risk that develops in distressed industries. All of these factors may complicate the ability of borrowers to achieve a favorable outcome in negotiating solutions to even marginally stressed credits.

Future debt financing arrangements, if available at all, may require collateral, higher interest rates and more restrictive terms. Collateral requirements and higher borrowing costs may limit our long- and short-term financial flexibility.

There are uncertainties in successfully integrating our acquisitions which could negatively impact our results of operations.

Although acquisitions have historically been an element of our business strategy, we cannot assure that we will be able to identify and acquire acceptable acquisition candidates on terms favorable to us in the future. We may be required to incur substantial indebtedness or issue equity to finance future acquisitions. Such additional debt service requirements may impose a significant burden on our results of operations and financial condition, and any equity issuance could have a dilutive impact on our stockholders. We cannot be certain that we will be able to successfully consolidate the operations and assets of any acquired business with our own business. Acquisitions may not perform as expected when the transaction was consummated and may be dilutive to our overall operating results. In addition, our management may not be able to effectively manage a substantially larger business or successfully operate a new line of business.

There are additional risks and uncertainties in successfully entering or growing a new line of business which could negatively impact our results of operations.

Historically, our operations and acquisitions focused primarily on offshore marine vessel services for the oil and gas industry. We have more recently expanded our capability to provide subsea services through the acquisition of employees with specialized subsea skills and ROVs. If an opportunity arises, we may expand our subsea capabilities further or potentially enter into a new line of business. Entry into, or further development of, lines of business in which we have not historically operated may expose us to business and operational risks that are different from those we have experienced historically. Our management may not be able to effectively manage these additional risks or implement successful business strategies in new lines of business. Additionally, our competitors in these lines of business may possess substantially greater operational knowledge, resources and experience than the company.

Any disruptions or disagreements with our foreign joint venture partners could negatively impact our results of operations and could lead to an unwinding of the joint venture which could negatively impact our revenues.

We operate in several foreign areas through joint ventures with local companies, in some cases as a result of local laws requiring local company ownership. While the joint venture partner may provide local knowledge and experience, entering into joint ventures often requires us to surrender a measure of control over the assets and operations devoted to the joint venture, and occasions may arise when we do not agree with the business goals and objectives of our partner, or other factors may arise that make the continuation of the relationship unwise or untenable. Any such disagreements or discontinuation of the relationship could disrupt our operations, put assets dedicated to the joint venture at risk, or affect the continuity of our business. If we are unable to resolve issues with a joint venture partner, we may decide to terminate the joint venture and either locate a different partner and continue to work in the area or seek opportunities for our assets in another market. The unwinding of an existing joint venture could prove to be difficult or time-consuming, and the loss of revenue related to the termination or unwinding of a joint venture and costs related to the sourcing of a new partner or the mobilization of assets to another market could adversely affect our financial condition, results of operations or cash flows. Please refer to Item 1 and Item 3 in this Annual Report on Form 10-K for additional discussion of our Sonatide joint venture in Angola and our joint venture in Nigeria, respectively.

Our international operations expose us to currency devaluation and fluctuation risk which could negatively impact our results of operations and financial position.

As a global company, our international operations are exposed to foreign currency exchange rate risks on all charter hire contracts denominated in foreign currencies. For some of our international contracts, a portion of the revenue and local expenses is incurred in local currencies and we are at risk of changes in the exchange rates between the U.S. dollar and foreign currencies. In some instances, we receive payments in currencies which are not easily traded and may be illiquid. We generally do not hedge against any foreign currency rate fluctuations associated with foreign currency contracts that arise in the normal course of business, which exposes us to the risk of exchange rate losses. Gains and losses from the revaluation of our monetary assets and liabilities denominated in currencies other than the U.S. dollar are included in our consolidated statements of operations. Foreign currency fluctuations may cause the U.S. dollar value of our non-U.S. results of operations and net assets to vary with exchange rate fluctuations. This could have a negative impact on our results of operations and financial position. In addition, fluctuations in currencies relative to currencies in which the earnings are generated may make it more difficult to perform period-to-period comparisons of our reported results of operations.

To minimize the financial impact of these items, we attempt to contract a significant majority of our services in U.S. dollars and, when feasible, we attempt to not maintain large, non-U.S. dollar-denominated cash balances. In addition, we attempt to minimize the financial impact of these risks by matching the currency of our operating costs with the currency of revenue streams when considered appropriate. We monitor the currency exchange risks associated with all contracts not denominated in U.S. dollars.

As of March 31, 2017, Sonatide maintained the equivalent of approximately $90 million of Angolan kwanza-denominated deposits in Angolan banks, largely related to customer receipts that had not yet been converted to U.S. dollars, expatriated and then remitted to us. A devaluation in the Angolan kwanza relative to the U.S. dollar would result in foreign exchange losses for Sonatide to the extent the Angolan kwanza-denominated asset balances were in excess of kwanza-denominated liabilities, 49% of which will be borne by us. Sonatide may be able to mitigate this exposure, but a hypothetical ten percent devaluation of the kwanza relative to the U.S. dollar on a net kwanza-denominated asset balance of $100 million would cause our equity in net earnings of unconsolidated companies to be reduced by $4.9 million.

Our insurance coverage and contractual indemnity protections may not be sufficient to protect us under all circumstances or against all risks which could negatively impact our results of operations.

Our operations are subject to the hazards inherent in the offshore oilfield business. These include blowouts, explosions, fires, collisions, capsizings, sinkings, groundings and severe weather conditions. Some of these events could be the result of (or exacerbated by) mechanical failure or navigation or operational errors. These hazards could result in personal injury and loss of life, severe damage to or destruction of property and equipment (including to the property and equipment of third parties), pollution or environmental damage and suspension of operations, increased costs and loss of business. Damages arising from such occurrences may result in lawsuits alleging large claims, and we may incur substantial liabilities or losses as a result of these hazards.

Our exposure to operating hazards may increase significantly with the expansion of our subsea operations, including through the ownership and operation of ROVs and the provision of engineering design and consulting services for customers’ subsea initiatives. For example, we may lose equipment, including ROVs, in the course of our subsea operations. This equipment may be difficult or costly to replace, and such losses may result in work stoppages or the loss of customers. Additionally, many of our subsea operations will be performed on or near existing oil and gas infrastructure. These operations may expose us to new or increased liability relating to explosions, blowouts and cratering; mechanical problems, including pipe failure; and environmental accidents, including oil spills, gas leaks or ruptures, uncontrollable flows of oil, gas, brine or well fluids, or other discharges of toxic gases or other pollutants. Finally, provision of engineering design and consulting services could expose us to professional liability for errors and omissions made in the course of those services.

We carry what we consider to be prudent levels of liability insurance, and our vessels and ROVs are generally insured for their estimated market value against damage or loss, including war, terrorism acts and pollution risks. While we maintain insurance protection and seek to obtain indemnity agreements from our customers requiring the customers to hold us harmless from some of these risks, our insurance and contractual indemnity protection may not be sufficient or effective to protect us under all circumstances or against all risks. Our insurance coverages are subject to deductibles and certain exclusions. We do not directly or fully insure for business interruption. The occurrence of a significant event not fully insured or indemnified against or the failure of a customer to meet its indemnification obligations to us could have a material and adverse effect on our results of operations and financial condition. Additionally, while we believe that we should be able to maintain adequate insurance in the future at rates considered commercially acceptable, we cannot guarantee that such insurance will continue to be available at commercially acceptable rates given the markets in which we operate.

Any determination that we have not complied with the Foreign Corrupt Practices Act or similar worldwide anti-bribery laws could negatively impact our results of operations.

Our global operations require us to comply with a number of U.S. and international laws and regulations, including those involving anti-bribery and anti-corruption. As a U.S. corporation, we are subject to the regulations imposed by the Foreign Corrupt Practices Act (FCPA), which generally prohibits U.S. companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business or obtaining an improper business benefit. We have adopted proactive procedures to promote compliance with the FCPA, but we may be held liable for actions taken by local partners or agents even though these partners or agents may themselves not be subject to the FCPA. Any determination that we have violated the FCPA (or any other applicable anti-bribery laws in countries in which we do business) could have a material adverse effect on our business and business reputation, as well as our results of operations, and cash flows.

Any determination that we have not complied and any changes to complex and developing laws and regulations to which the company is subject could negatively impact our results of operations.

Our operations are subject to many complex and burdensome laws and regulations. Stringent federal, state, local and foreign laws and regulations governing worker health and safety and the manning, construction and operation of vessels significantly affect our operations. Many aspects of the marine industry are subject to extensive governmental regulation by the United States Coast Guard, the United States Customs and Border Protection, and their foreign equivalents; as well as to standards imposed by private industry organizations such as the American Bureau of Shipping, the Oil Companies International Marine Forum, and the International Marine Contractors Association.

Further, many of the countries in which we operate have laws, regulations and enforcement systems that are less well developed than the laws, regulations and enforcement systems of the United States, and the requirements of these systems are not always readily discernible even to experienced and proactive participants. These countries’ laws can be unclear, and, the application and enforcement of these laws and regulations can be unpredictable and subject to frequent change or reinterpretation. Sometimes governments may apply such changes or reinterpretations with retroactive effect, and may impose associated taxes, fees, fines or penalties on the company based on that reinterpretation or retroactive effect. While we endeavor to comply with applicable laws and regulations, our compliance efforts might not always be wholly successful, and failure to comply may result in administrative and civil penalties, criminal sanctions, imposition of remedial obligations or the suspension or termination of our operations. These laws and regulations may expose us to liability for the conduct of, or conditions caused by, others, including charterers or third party agents. Moreover, these laws and regulations could be changed or be interpreted in new, unexpected ways that substantially increase costs that we may not be able to pass along to our customers. Any changes in laws, regulations or standards imposing additional requirements or restrictions could adversely affect our financial condition, results of operations or cash flows.

Any changes in the laws governing U.S. taxation of foreign source income could negatively impact our financial condition and cash flows.

We operate globally through various subsidiaries which are subject to changes in applicable tax laws, treaties or regulations in the jurisdictions in which we conduct our business, including laws or policies directed toward companies organized in jurisdictions with low tax rates. We determine our income tax expense based on our interpretation of the applicable tax laws and regulations in effect in each jurisdiction for the period during which we operate and earn income. A material change in the tax laws, tax treaties, regulations or accounting principles, or interpretation thereof, in one or more countries in which we conduct business, or in which we are incorporated or a resident of, could result in a higher effective tax rate on our worldwide earnings, and such change could be significant to our financial results. In addition, our overall effective tax rate could be adversely and suddenly affected by lower than anticipated earnings in countries with lower statutory rates and higher than anticipated earnings in countries with higher statutory rates, or by changes in the valuation of our deferred tax assets and liabilities.

Approximately 80% of our revenues and a majority of our net income are generated by our operations outside of the United States. Our effective tax rate has averaged approximately 30% since fiscal 2007, primarily a result of the passage of The American Jobs Creation Act of 2004, which excluded from our current taxable income in the U.S. income earned offshore through our controlled foreign subsidiaries.

Periodically, tax legislative initiatives are proposed to effectively increase U.S. taxation of income with respect to foreign operations. Whether any such initiatives will win congressional or executive approval and become law is presently unknown; however, if any such initiatives were to become law, and were such law to apply to our international operations, it could result in a materially higher tax expense, which would have a material impact on our financial condition, results of operations or cash flows, and which could cause us to review the utility of continued U.S. domicile.

In addition, our income tax returns are subject to review and examination by the U.S. Internal Revenue Service and other tax authorities where tax returns are filed. We routinely evaluate the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for taxes. We do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges our operational structure or intercompany transfer pricing policies, or if the terms of certain income tax treaties were to be interpreted in a manner that is adverse to our structure, or if we lose a material tax dispute in any country, our effective tax rate on our worldwide earnings could increase, and our financial condition and results of operations could be materially and adversely affected.

Any changes in environmental regulations could increase the cost of energy and future production of oil and gas which could negatively impact our results of operations.

Our operations are subject to federal, state, local and international laws and regulations that control the discharge of pollutants into the environment or otherwise relate to environmental protection. Compliance with such laws and regulations may require installation of costly equipment, increased manning or operational changes. Some environmental laws impose strict liability for remediation of spills and releases of oil and hazardous substances, which could subject us to liability without regard to whether we were negligent or at fault.

A variety of regulatory developments, proposals and requirements have been introduced (and in some cases enacted) in the U.S. and various other countries that are focused on restricting the emission of carbon dioxide, methane and other gases. Notwithstanding the current downturn in the oil industry punctuated by lessened demand and lower oil prices, any such regulations could ultimately result in the increased cost of energy as well as environmental and other costs, and capital expenditures could be necessary to comply with the limitations. These developments may have an adverse effect on future production and demand for hydrocarbons such as crude oil and natural gas in areas of the world where our customers operate and thus adversely affect future demand for our offshore support vessels, ROVs and other assets, which are highly dependent on the level of activity in offshore oil and natural gas exploration, development and production markets. In addition, the increased regulation of environmental emissions may create greater incentives for the use of alternative energy sources. Unless and until regulations are implemented and their effects are known, we cannot reasonably or reliably estimate their impact on our financial condition, results of operations and ability to compete. However, any long term material adverse effect on the crude oil and natural gas industry may adversely affect our financial condition, results of operations and cash flows.

Adoption of climate change and greenhouse gas restrictions could increase the cost of energy and future production of oil and gas which could negatively impact our results of operations.

Due to concern over the risk of climate change, a number of countries have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions. These include adoption of cap and trade regimes, carbon taxes, restrictive permitting, increased efficiency standards, and incentives or mandates for renewable energy. These requirements could make our customer’s products more expensive and reduce demand for hydrocarbons, as well as shift hydrocarbon demand toward relatively lower-carbon sources such as natural gas, any of which may reduce demand for our services.

Additional unionization efforts, new collective bargaining agreements or work stoppages could negatively impact our revenues.

In locations in which the company is required to do so, we have union workers, subject to collective bargaining agreements, that are periodically in negotiation. These negotiations could result in higher personnel expenses, other increased costs, or increased operational restrictions. Further, efforts have been made from time to time to unionize other portions of our workforce, including our U.S. GOM employees. We have also been subjected to threatened strikes or work stoppages and other labor disruptions in certain countries. Additional unionization efforts, new collective bargaining agreements or work stoppages could materially increase our costs and operating restrictions, reduce our revenues, or limit our flexibility.

The closing market price of our common stock has recently declined significantly. On April 18, 2017, we were notified by the NYSE that our common stock was not in compliance with NYSE listing standards. If we are unable to cure the market capitalization deficiency, our common stock could be delisted from the NYSE or trading could be suspended.

Our common stock is currently listed on the NYSE. In order for our common stock to continue to be listed on the NYSE, we are required to comply with various listing standards, including the maintenance of a minimum average closing price of at least $1.00 per share during a consecutive 30 trading-day period. On April 18, 2017, we were notified by the NYSE that the average price of our shares of common stock had fallen below $1.00 per share over a period of 30 consecutive trading days.

Additionally, under Section 802.01D of the NYSE Listed Company Manual, a company that files or announces an intent to file for relief under chapter 11 of the Bankruptcy Code may be subject to immediate suspension and delisting. However, if we are profitable or have positive cash flow, or if we are demonstrably in sound financial health despite the bankruptcy proceedings, the NYSE may evaluate our plan in light of the filing without immediate suspension and delisting of our common stock. We have been in active communication with the NYSE throughout this process and, to date, we have continued to trade on the NYSE.

In addition to potentially commencing suspension or delisting procedures in respect of our common stock if we fail to meet the material aspects of the plan or any of the quarterly milestones or if we file for bankruptcy and do not have positive cash flow or are not in sound financial health, our common stock could be delisted pursuant to Section 802.01 of the NYSE Listed Company Manual if the trading price of our common stock on the NYSE is abnormally low, which has generally been interpreted to mean at levels below $0.16 per share, and our common stock could also be delisted pursuant to Section 802.01 if our average market capitalization over a consecutive 30 day-trading period is less than $15 million. In these events, we would not have an opportunity to cure the market capitalization deficiency, and our shares would be delisted immediately and suspended from trading on the NYSE.

The commencement of suspension or delisting procedures by an exchange remains, at all times, at the discretion of such exchange and would be publicly announced by the exchange. If a suspension or delisting were to occur, there would be significantly less liquidity in the suspended or delisted securities. In addition, our ability to attract and retain personnel by means of equity compensation would be greatly impaired. Furthermore, with respect to any suspended or delisted securities, we would expect decreases in institutional and other investor demand, analyst coverage, market making activity and information available concerning trading prices and volume, and fewer broker-dealers would be willing to execute trades with respect to such securities. A suspension or delisting would likely decrease the attractiveness of our common stock to investors and cause the trading volume of our common stock to decline, which could result in a further decline in the market price of our common stock.

Additional issuances of equity securities by us would dilute the ownership of our existing stockholders and could reduce our earnings per share.

The Prepackaged Plan provides, among other things, that upon emergence from bankruptcy, our existing common stock will be cancelled and (i) the Noteholders will receive their pro rata share of 95% of the common stock in reorganized Tidewater and (ii) existing holders of common stock in Tidewater will receive their pro rata share of 5% of the common stock in reorganized Tidewater, plus warrants for ownership of up to 15% of reorganized Tidewater’s common equity exercisable upon the company reaching certain benchmarks pursuant to the terms of the proposed new warrants. Each of the foregoing common equity percentages in reorganized Tidewater is subject to dilution from the exercise of the new warrants described above and a management incentive plan.

Additionally, we may issue equity in the future in connection with capital raisings, debt exchanges, acquisitions, strategic transactions or for other purposes. To the extent we issue substantial additional equity securities, the ownership of our existing stockholders would be diluted, and our earnings per share could be reduced.

Information on Properties is contained in Item 1 of this Annual Report on Form 10-K.

For a discussion of our material legal proceedings, including “Arbitral Award for the Taking of the Company’s Venezuelan Operations” and “Nigeria Marketing Agent Litigation” see the “Legal Proceedings” section of “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 and Note (12) of Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Various legal proceedings and claims are outstanding which arose in the ordinary course of business. In the opinion of management, the amount of ultimate liability, if any, with respect to these actions, will not have a material adverse effect on the company’s financial position, results of operations, or cash flows.

On May 17, 2017, the Debtors filed Bankruptcy Petitions in the United States Bankruptcy Court for the District of Delaware seeking relief under the provisions of chapter 11 of the Bankruptcy Code. The commencement of the chapter 11 proceedings automatically stayed certain actions against the company, including actions to collect prepetition liabilities or to exercise control over the property of the Debtors. The Prepackaged Plan in the chapter 11 proceedings provides for the treatment of prepetition liabilities that have not otherwise been satisfied or addressed during the chapter 11 cases. The Bankruptcy Court set a combined hearing to consider approval of the Debtors’ disclosure statement and confirmation of the Prepackaged Plan for June 28, 2017. We expect the Prepackaged Plan to become effective in July 2017, at which point or shortly thereafter the Debtors would emerge from bankruptcy, however, there can be no assurance that the effectiveness of the Prepackaged Plan will occur on such date, or at all. For additional information on the bankruptcy proceedings, see Part II. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

ITEM 5. MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITY SECURITIES

In May 2014, the company’s Board of Directors authorized the company to spend up to $200 million to repurchase shares of its common stock in open-market or privately-negotiated transactions. In May 2015, the company’s Board of Directors authorized an extension of its May 2014 common stock repurchase program from its original expiration date of
June 30, 2015 to June 30, 2016. In fiscal 2015, $100 million was used to repurchase common stock under the May 2014 share repurchase program. No shares were repurchased by the company during fiscal 2016 or fiscal 2017.

The value of common stock repurchased, along with number of shares repurchased, and average price paid per share for the years ended March 31, are as follows:

The declaration of dividends is at the discretion of the company’s Board of Directors. The Board of Directors declared the following dividends for each of the last three years ended March 31, as follows:

The following graph compares the cumulative total stockholder return on the company’s common stock against the cumulative total return of the Standard & Poor’s 500 Stock Index and the cumulative total return of the Value Line Oilfield Services Group Index (the “Peer Group”) over the last five fiscal years.
