PART I

ITEM 1.    BUSINESS

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 majority and sometimes minority interests (where required to satisfy local ownership or content requirements). Unless otherwise required by the context, the term “company” as used herein refers to Tidewater Inc. and its consolidated subsidiaries.

About Tidewater

The company provides offshore vessel services in support of all phases of offshore exploration, field development and production, including towing of, and anchor handling for, mobile offshore drilling units; transporting supplies and personnel necessary to sustain drilling, workover and production activities; offshore

4

construction, ROV operations, and seismic support; and a variety of specialized services such as pipe and cable laying. The size and composition of the company’s offshore service vessel fleet includes vessels that are operated under joint ventures, as well as vessels that have been stacked or withdrawn from service.

The company has one of the broadest operating global footprints in the offshore energy industry with operations in most of the world’s significant crude oil and natural gas exploration and production offshore regions so we can be close to our customers. Our wide operating footprint facilitates strong customer relationships and the ability to react quickly to local market conditions and changing customer needs. The company is also one of the most experienced international operators in the offshore energy industry with over five decades of international experience.

At March 31, 2012, the company had 342 vessels (of which 10 were owned by joint ventures, 67 were stacked and two were withdrawn from service) available to serve the global energy industry. Please refer to Note (1) of Notes to Consolidated Financial Statements included in Item 8 of this report for additional information regarding our stacked vessels and vessels withdrawn from service.

The company also operates two shipyards, which construct, modify and repair vessels. The shipyards perform both repair work and new construction work for outside customers, as well as the construction, repair and modification of the company’s own vessels.

Our revenues, net earnings and cash flows from operations are largely dependent upon the activity level of our offshore marine vessel fleet. As is the case with other energy service companies, our business activity is largely dependent on the level of drilling and exploration 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.

Offices and Facilities

The company’s worldwide headquarters and principal executive offices are located at 601 Poydras Street, Suite 1900, New Orleans, Louisiana 70130, and its telephone number is (504) 568-1010. The company’s U.S. marine operations are based in Amelia, Louisiana; Oxnard, California; and Houston, Texas. The company’s shipyards and shipyard operations are located in Houma, Louisiana. 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; Cairo, Egypt; Luanda and Cabinda, Angola; Lagos and Onne Port, Nigeria; Douala, Cameroon; Singapore; Perth, Australia; Shenzhen, China; Port Moresby, Papua New Guinea; Al Khobar, Kingdom of Saudi Arabia, and Dubai, United Arab Emirates. The company’s operations generally do not require highly specialized facilities, and suitable facilities are generally available on a lease basis as required.

Business Segments

During the quarter ended September 30, 2011, our International and United States segments were reorganized to form four new operating segments. We now manage and measure our business performance in four distinct operating segments which are based on our geographical organization: Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. Management decided to revise its reporting segments, largely because the company’s Sub-Saharan Africa/Europe and Latin American business regions had gained greater significance as a percentage of consolidated revenues and operating profit, while our former United States segment had declined in significance to consolidated revenues and operating profit. Prior period disclosures have been recast to reflect the change in reportable segments.

Our Americas segment includes the activities of our North American operations, which include the U.S. GOM and U.S. coastal waters of the Pacific and Atlantic oceans, Mexico, Trinidad and Brazilian operations. The Asia/Pacific segment includes our Australian and Southeast Asia and Pacific operations. Middle East/North Africa includes our operations in Egypt, the Arabian Gulf and India. Lastly, our Sub-Saharan Africa/Europe segment includes operations conducted along the East and West Coasts of Africa as well as operations around the Caspian Sea and the North Sea.

5

The principal customers in each of these business segments are major and independent oil and natural gas exploration, field development and production companies; foreign government-owned or government-controlled organizations and other companies that explore and produce oil and natural gas; 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 geographically dispersed throughout the major offshore crude oil and natural gas exploration and development 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 international 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 vessel assets enable the company to respond relatively quickly to changing market conditions. As such, significant variations between various regions tend to be of a short-term duration, as we routinely move vessels between and within geographic regions.

Revenues in each of our segments are derived primarily from vessel time charter contracts that are generally three months to three years in duration as determined by customer requirements, and from time charter contracts on a “spot” basis, which is a short-term agreement (one day to three months) 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 include clauses to recover specific additional costs.

In each of our business segments, and depending on vessel capabilities and availability, our vessels operate in the shallow, intermediate and deepwater offshore markets of the respective regions. The deepwater offshore market continues to be a growing sector in the offshore crude oil and natural gas markets due to technological developments that have made such exploration feasible. It is the one sector that has not experienced significant negative effects from the 2008-2009 global economic recession, largely because deepwater exploration and development typically involves significant capital investment and multi-year development plans. Such projects are generally underwritten by the participating exploration, development and production companies using relatively conservative assumptions in regards to crude oil and natural gas prices and therefore are not as susceptible to short-term fluctuations in the price of crude oil and natural gas. However, the April 2010 Deepwater Horizon incident did negatively affect the level of drilling activity off the continental shelf of the U.S. Gulf of Mexico (GOM) while the U.S. Department of the Interior, through the Bureau of Ocean Energy Management Regulation and Enforcement (BOEMRE) evaluated the causes of the incident and announced plans for enhanced regulatory and safety oversight as a condition to granting additional drilling and exploration permits. The BOEMRE resumed deepwater exploration and drilling permitting by February 2011, although the pace of permitting has been slow. Also, in our Americas segment, drilling activity in the shallow and intermediate waters of the U.S. GOM has been negatively impacted by low natural gas prices.

Please refer to Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this report for a greater discussion of the company’s segments, including the macroeconomic environment we operated under. In addition, please refer to Note (14) of Notes to Consolidated Financial Statements included in Item 8 of this report for segment, geographical data and major customer information.

Geographic Areas of Operation

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 Persian/Arabian Gulf, and areas offshore Australia, Brazil, China, Egypt, India, Indonesia, Malaysia, Mexico, Thailand, Trinidad, and West and East Africa. The company regularly evaluates the deployment of its assets and repositions its vessels based on customer demand, relative market conditions, and other considerations.

Please refer to Item 7 of this report and Note (14) of Notes to Consolidated Financial Statements included in Item 8 of this report for further disclosure of segment revenues, operating profits, and total assets by geographical areas in which the company operates.

Our Global Vessel Fleet

The company continues a disciplined vessel construction, acquisition and replacement program that was initiated with the intent of assuring the company’s presence in nearly all major oil and gas producing regions of the world through the replacement of aging vessels in the company’s fleet with fewer, larger, and more technologically sophisticated vessels. Since calendar 2000, the company has purchased and/or constructed 238 vessels at a total cost of approximately $3.4 billion and at March 31, 2012, has an additional 25 vessels under construction or committed to be purchased at a total cost of approximately $616.7 million. To date, the company has generally funded its vessel programs from its operating cash flows, funds provided by three private debt placements totaling $890 million in senior unsecured notes, a $125 million term bank loan, borrowings under revolving credit facilities, and various sales-leaseback arrangements.

The company’s strategy contemplates organic growth through the construction of vessels at a variety of shipyards worldwide and possible acquisitions of recently built vessels and/or other owners and operators having attractive offshore supply vessels and/ or vessel operations. The company has the largest number of new offshore supply vessels among its competitors in the industry, but it also has the largest number of older offshore supply vessels for which management regularly evaluates disposition and other alternatives. The company intends to pursue its long-term fleet replenishment and modernization strategy on a disciplined basis and, in each case, will carefully consider whether proposed investments and transactions have the appropriate risk/reward profile.

The average age of the company’s 330 owned or chartered vessel fleet (excluding joint-venture vessels and vessels withdrawn from service) in its fleet at March 31, 2012 is approximately 14.0 years. The average age of 215 newer vessels in the fleet (defined as those that have been acquired or constructed since calendar year 2000 as part of the company’s new build and acquisition program as discussed below) is approximately 5.7 years. The remaining 115 vessels have an average age of 29.6 years. Of the company’s 330 vessels,

7

72 are deepwater class vessels, 185 are in the non-deepwater towing-supply/supply class vessels, 52 are crew/utility class vessels and 21 are offshore tugs.

At March 31, 2012, the company had agreements to acquire three vessels and commitments to build 22 vessels at a number of different shipyards around the world (with one of these vessels being constructed in the United States by the company’s wholly-owned shipyard, Quality Shipyards, L.L.C.) at a total cost, including contract costs and other incidental costs, of approximately $616.7 million. Of the 22 new-build vessels, two are anchor handling towing supply (AHTS) vessels and have 8,200 brake horsepower (BHP), 15 are platform supply vessels (PSVs) ranging between 1,900 and 6,360 deadweight tons of cargo capacity, one is a fast crew/supply boat and four are crewboats. Scheduled delivery for these newbuild vessels began in April 2012, with delivery of the final vessel expected in May 2014. The company currently is experiencing substantial delay with one fast, crew/supply boat under construction in Brazil that was originally scheduled to be delivered in September of 2009. A discussion of this matter is disclosed in the “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 and Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report.

Of the three vessels to be purchased, all three are deepwater PSVs. The aggregate approximate purchase price for these vessels is $58.4 million. The company took possession of one of the PSVs, which has 3,000 deadweight tons of cargo capacity, in April 2012 for a total cost of $19.8 million and expects to take possession of the remaining two PSVs, which have 3,500 deadweight tons of cargo capacity, in July 2012 and in September 2012 for a total aggregate cost of $38.6 million.

At March 31, 2012, the company had invested $244.5 million in progress payments towards the construction of 22 vessels and $12.9 million towards the purchase of the three PSVs. At March 31, 2012, the remaining expenditures necessary to complete construction of the 22 vessels currently under construction (based on contract prices) and to fund the acquisition of the three vessels was $359.3 million.

A discussion of the company’s capital commitments, scheduled delivery dates and vessel sales is disclosed in the “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 and Note (11) of Notes to Consolidated Financial Statements. The “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 also contains a table comparing the actual March 31, 2012 vessel count and the average number of vessels by class and geographic distribution during the three years ended March 31, 2012, 2011 and 2010.

Between April 1999 and March 2012, the company also sold, primarily to buyers that operate outside of our industry, 603 vessels. Most of the vessel sales were at prices that exceeded their carrying values. The vessel sales were accompanied by sales restrictions on competition or else the company determined that the prospects of the vessel competing with our ongoing business were low. In aggregate, proceeds from, and pre-tax gains on, vessel dispositions during this period approximated $650 million and $300 million, respectively.

Our Vessel Classifications

Our vessels regularly and routinely move from one operating area to another, often to and from offshore operating areas of different continents. We disclose our vessel statistical information, such as revenue, utilization and average day rates, by vessel class. Listed below are our five major vessel classes along with a description of the type of vessels categorized in each class and the services the respective vessels typically perform. Tables comparing the average size of the company’s marine fleet by class and geographic distribution for the last three fiscal years are included in Item 7 of this report.

Deepwater Vessels

Included in this vessel class are large (typically greater than 230-feet and/or with at least 2,801 tons in dead weight cargo carrying capacity) PSVs and large, higher-horsepower (generally greater than 10,000 horsepower) AHTS vessels. This vessel class is generally chartered to customers for use in transporting supplies and equipment from shore bases to deepwater and intermediate water depth offshore drilling rigs, platforms and other installations that operate in challenging environments and which typically involve complex projects. Platform supply vessels, which have large cargo capacities [both below deck (liquid mud tanks and dry bulk tanks) and above deck cargo capacities], serve drilling and production facilities and support offshore construction and maintenance work. The deepwater AHTS vessels are equipped to tow drilling rigs and other

8

marine equipment, as well as to set anchors for the positioning and mooring of drilling rigs. Due to the challenging environment that deepwater offshore rigs, platforms and other installations operate in, our deepwater AHTS and PSVs are outfitted with dynamic positioning (anchorless station-keeping) capabilities, which are primarily driven by safety considerations that preclude vessels from physically mooring to the installations and because our customers demand a high level of safety and technological advancements to meet the more stringent regulatory standards especially in the wake of the Deepwater Horizon incident.

This class of vessel also includes specialty vessels that can support offshore well stimulation, construction work, subsea services and/or have fire fighting capabilities and/or accommodation facilities. These vessels are generally available for routine supply and towing services but are 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), which is designed for subsea service and construction support activities and which is significantly larger in size, more versatile, and more specialized than the PSVs discussed above. The MPSV also commands a higher day rate because the vessel has higher construction cost, operating costs and because of the aforementioned capabilities.

Towing-Supply and Supply Vessels

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

Crewboats and Utility Vessels

Crewboats 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

Offshore tugs tow floating drilling rigs; assist in the docking of tankers; tow barges; assist pipe laying, cable laying and construction barges; and are used in a variety of other commercial towing operations, including towing barges carrying a variety of bulk cargoes and containerized cargo.

Other Vessels

The company’s “Other Vessels” included inshore tugs and production, line-handling and various other special purpose vessels. Inshore tugs, which are operated principally within inland waters, tow drilling rigs to and from their locations and tow-barges carrying equipment and materials for use principally in inland waters for drilling and production operations. Barges are either used in conjunction with company tugs or are chartered to others. The company sold its remaining “other” type vessels during the first quarter of fiscal 2010.

Revenue Contribution of Main Classes of Vessels

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

	Year Ended March 31,
	2012		2011		2010
Deepwater vessels		44.2%		39.6%		31.9%
Towing-supply/supply		44.9%		49.2%		56.9%
Crew/utility		7.7%		7.8%		7.9%
Offshore tugs		3.2%		3.4%		3.3%

Shipyard Operations

Quality Shipyards, L.L.C., a wholly-owned subsidiary of the company, operates two shipyards in Houma, Louisiana, that construct, upgrade and repair vessels. The shipyards perform repair work and new construction work for third-party customers, as well as the construction, repair and modification of the company’s own vessels. During the last three fiscal years, Quality Shipyards, L.L.C. has constructed and delivered three 266-foot PSVs, and is currently constructing one 261-foot PSV for the company that is scheduled for delivery in October 2013. One of the 266-foot platform supply vessels was delivered in November 2011, while the other two were delivered at various times during fiscal 2010.

Customers and Contracting

The company’s operations are materially 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 are 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. A discussion of current market conditions and trends appears under “Macroeconomic Environment and Outlook” in Item 7 of this report.

The company’s principal customers are major and independent oil and natural gas exploration, field development and production companies; foreign government-owned or government-controlled organizations and companies that explore and produce oil and natural gas; drilling contractors; and companies that provide other services to the offshore energy industry, including but not limited to, offshore construction companies, diving companies and well stimulation companies.

In recent years, consolidation of exploration, field development, and production companies has occurred which reduces the number of customers for the company’s vessels and services, and may negatively affect exploration, field development and production activity as consolidated companies generally focus initially on increasing efficiency and reducing costs and delay or abandon exploration activity with less promise. Such activity could adversely affect demand for our vessels, and reduce the company’s revenues. This trend is likely to continue in the future, although for every merger in the industry, there is frequently a start-up company that takes the place of the merged company, in numerical terms, if not in levels of activity.

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 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 the years ended March 31:

	2012			2011			2010
Chevron Corporation (including its worldwide subsidiaries and affiliates)		17.4	%		16.2	%		18.3	%
Petroleo Brasileiro SA		14.6	%		15.4	%		13.1	%

While it is normal for our customer base to change over time as our time charter contracts turn over, the unexpected loss of either or both of these two 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. The five largest customers of the company in aggregate accounted for approximately 43% of our fiscal 2012 total revenues, while the 10 largest customers in aggregate accounted for approximately 59% of the company’s fiscal 2012 total revenues.

Competition

The principal competitive factors for the offshore vessel service industry are the suitability and availability of vessel 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 the company has a competitive advantage because of the size, diversity and geographic distribution of our vessel fleet. Economies of scale and experience level in the many areas of the world in which we operate are also considered competitive advantages as is the company’s strong financial position.

According to ODS-Petrodata, the global offshore supply vessel market at the end of April 2012 had approximately 410 new-build offshore support vessels (PSVs and anchor handlers only), under construction that are expected to be delivered to the worldwide offshore vessel market primarily over the next three years. The current worldwide fleet of these classes of vessels is estimated at approximately 2,745 vessels, of which Tidewater estimates more than 10% are stacked. An increase in worldwide vessel capacity could have the effect of lowering charter rates, particularly when there are lower levels of exploration, field development and production activity. The worldwide offshore marine vessel industry, however, also has a large number of aged vessels, including approximately 725 vessels, or 26%, 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, approximately one-third of which Tidewater estimates are already stacked, could potentially be removed from the market within the next few years if the cost of extending the vessels’ lives is not economically justifiable. Although the future attrition rate of these aging vessels cannot be determined with absolute certainty, the company believes that the retirement of a sizeable portion of these aged vessels could mitigate the potential negative effects of new-build vessels on vessel utilization and vessel pricing. Additional vessel demand could also be created by the addition of new drilling rigs and floating production units that are expected to be delivered and become operational over the next few years, which should help minimize the possible negative effects of the new-build offshore support vessels being added to the offshore support vessel fleet.

Challenges We Confront as an International Offshore Vessel Company

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 controls, 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 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 the company to 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.

Sonatide Joint Venture

The company has previously announced that its existing Sonatide joint venture agreement with Sonangol had been extended to May 31, 2012 to allow ongoing joint venture restructuring negotiations to continue.

The company has from time to time also provided updates regarding the status of its continuing negotiations with Sonangol to put its Sonatide joint venture on a more permanent footing after a number of temporary

11

extensions of the original joint venture agreement. As previously disclosed, in March 2012, Sonangol informed Tidewater that it would not permit further vessel contracting activity by Sonatide until the joint venture negotiations had been resolved to the parties’ mutual satisfaction. As a result, the company has begun deploying vessels (at prevailing market day rates) to other markets as those vessels become available.

The company has recently exchanged proposals and is continuing discussions with Sonangol. In the most recent meeting between the two negotiating teams, only modest progress was made in the restructuring negotiations, and important and fundamental issues regarding the restructured relationship remain outstanding and unresolved. In that meeting, Sonangol and the company discussed a number of topics, up to and including the potential issues associated with a wind up of the existing joint venture in the event restructuring discussions are not ultimately successful. If negotiations relating to putting the Sonatide joint venture on a more permanent footing are ultimately unsuccessful, the company will work toward an orderly wind up of the joint venture. We believe, however, that the joint venture would be allowed to honor existing vessel charter agreements through their contract terms. Even though the global market for offshore supply vessels appears to be well balanced (and the market for deepwater supply vessels is currently strong), there would be financial impacts associated with the wind up of the existing joint venture and the possible redeployment of vessels to other markets, including mobilization costs and costs to redeploy Tidewater shore-based employees to other areas, in addition to lost revenues associated with potential downtime between vessel contracts. These financial impacts could, individually or in the aggregate, be material to our results of operations and cash flows. If there is a need to redeploy vessels which are currently deployed in Angola to other international markets, Tidewater believes that there is sufficient demand for these vessels at prevailing market day rates.

For the year ended March 31, 2012, Tidewater’s Angolan operations generated vessel revenues of approximately $254 million, or 24% of its consolidated vessel revenue, from an average of approximately 93 vessels (14 of which were stacked on average in fiscal 2012), and, for the year ended March 31, 2011, generated vessel revenues of approximately $237 million, or 23% of consolidated vessel revenue, from an average of approximately 97 vessels (13 of which were stacked on average in fiscal 2011). As of March 31, 2012, the carrying value of Tidewater’s investment in the Sonatide joint venture, which is included in “Investments in, at equity, and advances to unconsolidated companies,” is approximately $46 million.

International Labour Organization’s Maritime Labour Convention

The International Labour Organization’s Maritime Labour Convention, 2006 (the “Convention”) seeks to mandate globally, among other things, seafarer working conditions, ship accommodations, wages, conditions of employment, health and other benefits for all ships (and the seafarers on those ships) that are engaged in commercial activities. To date, this Convention has been ratified by 25 countries, namely, Antigua and Barbuda, Australia, the Bahamas, Benin, Bosnia and Herzegovina, Bulgaria, Canada, Croatia, Denmark, Kiribati, Latvia, Liberia, Luxembourg, Marshall Islands, Netherlands, Norway, Panama, Poland, Saint Kitts and Nevis, St. Vincent and the Grenadines, Singapore, Spain, Switzerland, Togo and Tuvalu. Instruments of ratification have been received but registration is pending for Gabon. The aforementioned 26 countries represent more than 50% of the world’s vessel tonnage. If 30 Member States ratify the Convention, then, within 12 months thereof, the Convention will become law. Even though the company believes that the labor changes proposed by this Convention are unnecessary in light of existing international labor laws that govern many of these issues, and the company continues to work with industry representatives to oppose ratification of this Convention, the company continues to assess its seafarer labor relationships, including benefits provided, and to review its fleet operational practices in light of the Convention requirements. Should this Convention become law, the company and its customers’ operations may be negatively affected by future compliance costs.

Government Regulation

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.

12

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 18% of the company’s outstanding common stock was owned by non-U.S. citizens as of March 31, 2012.

The laws of the U.S. require that vessels engaged in the U.S. coastwise trade must be built in the U.S. 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. Of the total 342 vessels owned or operated by the company at March 31, 2012, 290 vessels were registered under flags other than the United States and 52 vessels were registered under the U.S. flag. If the company is not able to secure adequate numbers of charters abroad for its non-U.S. flag vessels, even if work would otherwise have been available for such vessels in the United States, these vessels cannot operate in the U.S. coastwise trade, and the company’s financial performance could be affected.

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 towing-supply, 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 Code (ISPS), 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.

Environmental Compliance

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, injunction 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.

All vessels over 79 feet in registered length, regardless of flag, that are operating as a means of transportation within the inland and offshore waters of the U.S. (but not beyond the three nautical mile territorial sea limit) must comply with the Environmental Protection Agency’s National Pollutant Discharge Elimination System (NPDES) Vessel General Permit (VGP) for discharges incidental to the normal operation of vessels. For our vessels, that includes ballast water, bilge water, graywater, cooling water, chain locker effluent, deck wash down and runoff, cathodic protection, and other such type runoff. The company believes that it is in full compliance with the VGP.

13

The company is also involved in various legal proceedings that relate to asbestos and other environmental matters. In the opinion of management, based on current information, 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.

Safety

We are committed to ensuring the safety of our operations for both our employees and our customers. The company’s principal operations occur in offshore waters where the workplace environment presents safety challenges. Because the work environment presents these challenges, the company works diligently to maintain workplace safety. Management regularly communicates with its personnel to promote safety and instill safe work habits through company media and safety review sessions. We also regularly conduct safety training meetings for our seamen and shore based staff personnel. We dedicate personnel and resources to ensure safe operations and regulatory compliance. Our Director of Health, Safety and Environmental Management is involved in proactive efforts to prevent accidents and injuries and reviews all incidents that occur throughout the company. In addition, the company employs safety personnel at every operating location who are responsible for administering the company’s safety programs and fostering the company’s safety culture. We believe that every employee is a safety supervisor, and gives each employee the right, the responsibility, and the obligation to stop any operation that the employee deems to be unsafe, whether it is deemed to be, in retrospect, unsafe or not.

Risk Management

The operation of any marine vessel involves an inherent risk of marine losses attributable to adverse sea and weather conditions, mechanical failure, and collisions, as well as, physical damage to the vessel. 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, pirates and terrorism, as well as business interruption due to political action or inaction, including nationalization of assets by foreign governments. Any such event may result in 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 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 by maintaining a self-retention layer up to certain limits on its marine package policy. 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.-owned 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 our 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 such with the current level of uncertainty in the markets the company operates.

Raw Materials

The company’s wholly-owned subsidiary, Quality Shipyards, L.L.C., performs both repair work and new construction work for outside customers, as well as the construction, repair and modification of the company’s own vessels. The shipyard operations require raw materials, such as alloy steels in various forms, welding gases, paint, fuels and lubricants, which are available from multiple sources and subject to price volatility. The shipyard does not depend on any one supplier or source for any of these materials. Although shortages for some of these materials and fuels have occurred from time to time, no material shortage currently exists nor does the shipyard anticipate any shortages. The commodity price for iron ore, the main component of steel, is typically volatile, and shortages may occur from time to time.

Seasonality

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, monsoon season, and severe weather can impact operations. 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 U.S. GOM. 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 in Southeast Asia and Pacific are impacted by the monsoon season, which moves across the region from November to April. The 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 during the non-cyclone season and, as such, the impact of cyclone season on our operations is not significant. Although hurricanes, cyclones, monsoons and other severe weather can impact 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 conditions for the company’s offshore marine services than any seasonal variation.

Employees

As of March 31, 2012, the company had approximately 7,650 employees worldwide. The company strives to maintain excellent relations with its employees. 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.

ITEM 1A.  RISK FACTORS

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 identified as affecting or potentially affecting our company and the offshore marine service industry. In addition, we are also subject to a variety of risks and uncertainties not known to us or that we currently believe are not as significant as the risks described below. You should consider these risks when evaluating any of the company’s forward-looking statements. The effect of any one risk factor or a combination of several risk factors could materially affect the company’s 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.

Oil and Gas Prices Are Highly Volatile

Commodity prices for crude oil and natural gas are highly volatile. Prices are extremely sensitive to the respective supply/demand relationship for crude oil and natural gas. High demand for crude oil and natural gas, reductions in supplies and/or low inventory levels for these resources as well as any perceptions about future supply interruptions can cause prices for crude oil and natural gas to rise. Conversely, low demand for crude oil and natural gas, increases in supplies and/or increases in crude oil and natural gas inventories cause prices for crude oil and natural gas to decrease. In addition, global military, political, and economic events, including civil unrest in the Middle East and North Africa oil producing and exporting countries, have contributed to crude oil and natural gas price volatility.

Factors that affect the supply of crude oil and natural gas include, but are not limited to, the following: global demand for the hydrocarbons; the Organization of Petroleum Exporting Countries’ (OPEC) ability to control crude oil production levels and pricing, as well as, the level of production by non-OPEC countries; sanctions imposed by the U.S., the European Union, or other governments against oil producing countries; political and economic uncertainties (including wars, terrorist acts or security operations); advances in exploration and field development technologies; significant weather conditions; and governmental policies/restrictions placed on exploration and production of natural resources.

Prolonged material downturns 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, which would likely result in a corresponding decline in demand for offshore support vessel services and a reduction in charter rates and/or utilization rates, which would have a material adverse effect on our results of operations, cash flows and financial condition. Higher commodity prices, however, do not necessarily translate into increased demand for offshore support vessel services as increased commodity supply could come from land-based energy markets.

Crude oil pricing volatility has increased in recent years as crude oil has emerged into a financial asset class used for speculative purchase. Traditionally, crude oil futures and options were purchased by the commercial traders for future production in an effort to hedge against price risk. More recently, non-commercial market participants have traded crude oil derivatives to profit off of the price performance of crude oil instead of traditional investments. The extent to which speculation causes excessive crude oil pricing volatility is currently not fully known; however, there is a growing consensus that speculative purchase of crude oil futures and options helped push crude oil prices to record levels in mid-2008.

Changes in the Level of Capital Spending by Our Customers

Our principal customers are major and independent oil and natural gas exploration, field development and production companies; foreign government-owned or -controlled organizations and companies that explore and produce oil and natural gas; drilling contractors; and companies that provide other services to the offshore energy industry, such as, offshore construction companies, diving companies and well stimulation companies. Demand for our vessels, and thus our results of operations are highly dependent on the level of capital spending for exploration and field development by the companies that operate in the energy industry. 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

17

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 level of offshore crude oil and natural gas exploration, development and production activity has historically been volatile, and that volatility is likely to continue.

Other factors that influence the level of capital spending by our customers that are beyond our control include: worldwide demand for crude oil and natural gas; the cost of offshore exploration and production of crude oil and natural gas, which can be affected by environmental regulations; significant weather conditions; technological advances that affect energy production and consumption; local and international economic and political environment; the availability and cost of financing.

Consolidation of the Company’s Customer Base

Oil and natural gas companies, energy companies and drilling contractors have undergone consolidation, and additional consolidation is possible. Consolidation reduces the number of customers for the company’s equipment, and may negatively affect exploration, field development and production activity as consolidated companies focus on increasing efficiency and reducing costs and delay or abandon exploration activity with less promise. Such activity could adversely affect demand for the company’s vessels and reduce the company’s revenues.

The Offshore Marine Service Industry is Highly Competitive

We operate in a highly competitive industry, which could depress vessel charter rates and utilization 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 vessels; availability of vessels; safety and efficiency; cost of mobilizing vessels 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 that favor or require local ownership. In general, declines in the level of offshore drilling and development activity by the energy industry negatively affects the demand for our vessels and results in downward pressure on day rates. Extended periods of low vessel demand and/or low day rates reduce the company’s revenues.

Risk Associated With the Loss of a Major Customer

We derive a significant amount of revenue from a few customers. For the years ended March 31, 2012, 2011 and 2010, the five largest customers accounted for approximately 43%, 45%, and 47%, respectively, of the company’s total revenues, while the 10 largest customers accounted for a respective 59%, 63%, and 62% of our total revenues. While it is normal for our customer base to change over time as our time charter contracts turn over, our results of operations, financial condition and cash flows could be materially adversely affected if one or more of these customers decide to interrupt or curtail their activities; terminate their contracts with us; fail to renew existing contracts; and/or refuse to award new contracts, and we were unable to contract our vessels with new customers at comparable day rates.

Unconventional Natural Gas Sources are Exerting Downward Pricing Pressures on the Price of Natural Gas

The rise in production of unconventional gas resources (onshore shale plays resulting from technological advancements in horizontal drilling and fracturing) in North America and the commissioning of a number of new large Liquefied Natural Gas (LNG) export facilities around the world are contributing to an over-supplied natural gas market. While production of natural gas from unconventional sources is still a relatively small portion of the worldwide natural gas production, it is increasing because improved drilling efficiencies are lowering the costs of extraction. There is a significant oversupply of natural gas inventories in the United States in part due to the increase of unconventional gas in the market. Prolonged increases in the worldwide supply of natural gas, whether from conventional or unconventional sources, will likely continue to weigh on natural gas prices. A prolonged period of low natural gas prices would likely have a negative impact on development plans of exploration and production companies (at least in regards to development plans primarily targeting natural gas), which in turn, may result in a decrease in demand for offshore support vessel services. This effect could be particularly acute in our Americas segments, specifically our shallow water U.S. GOM operations, which is

18

more oriented towards natural gas than crude oil production, and therefore more sensitive to the changes in the market pricing for natural gas than to changes in the market pricing of crude oil.

Challenging Macroeconomic Conditions

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 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 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 or security operations) can have a material negative effect on our business and operations, which in turn would reduce our revenues and profitability.

Prolonged material economic downturns in crude oil and natural gas prices can negatively affect the development plans of exploration and production companies. In addition, a prolonged recession may result in a decrease in demand for offshore support vessel services and a reduction in charter rates and/or utilization rates, which would have a material adverse effect on the company’s results of operations, cash flows and financial condition. Prior to mid-2008, oil and gas companies had increased their respective exploration and field development activities in response to a very favorable pricing environment for oil and gas that existed at that time. Worldwide demand for crude oil and natural gas dropped precipitously and energy prices sharply declined as a result of a 2008-2009 global economic recession. Several years later, there are signs that economic improvement is underway; however, the pace of recovery and demand for energy and, in turn, offshore supply vessel services is still recovering. In addition, the recent increases in crude oil prices, resulting from higher demand for hydrocarbons and civil unrest in the Middle East and North African oil producing and exporting countries, renewed economists’ concerns that high energy prices could imperil the economic recovery, although high commodity pricing generally bodes well for the energy industry.

Potential Overcapacity in the Offshore Marine Industry

Over the past decade, as offshore exploration and production activities increasingly focused on deepwater well exploration, field development and production, offshore service companies, such as ours, constructed specialized offshore vessels that are capable of supporting complex deepwater and deep well (defined by well depth rather than water depth) projects that are generally located in challenging environments. During this time, construction of offshore vessels increased significantly in order to meet customer demands. Excess offshore supply vessel capacity usually exerts downward pressure on charter day rates. Excess capacity can occur when newly constructed vessels enter the market and also when vessels migrate between market areas. While the company is committed to the construction of additional vessels, it has also sold and/or scrapped a significant number of vessels over the last several years. A discussion about the aging of the company’s fleet, which has necessitated the company’s new vessel construction programs, appears in the “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 in this report.

The offshore supply vessel market has approximately 410 new-build offshore support vessels (platform supply vessels and anchor handlers only), under construction that are expected to be delivered to the worldwide offshore vessel market primarily over the next three years, according to ODS-Petrodata. The current worldwide fleet of these classes of vessels is estimated at approximately 2,745 vessels, according to the same source. An increase in vessel capacity could result in increased competition in the company’s industry 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 the Shipping Act 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 the Shipping Act, or the administrative erosion of its benefits, permitting vessels that are either foreign-flagged, foreign-built, foreign-owned, foreign-controlled or foreign-

19

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.

Risks Associated with Vessel Construction and Maintenance

The company has a number of vessels currently under construction, and it may construct additional vessels in response to current and future market conditions. In addition, the company routinely engages shipyards to drydock vessels for regulatory compliance and to provide repair and maintenance services. Construction projects and drydockings are subject to risks of delay and cost overruns, resulting from shortages of equipment, materials and skilled labor; lack of shipyard availability; unforeseen design and engineering problems; work stoppages; weather interference; unanticipated cost increases; unscheduled delays in the delivery of material and equipment; financial and other difficulties at shipyards including labor disputes and shipyard insolvency; and inability to obtain necessary certifications and approvals.

A significant delay in either construction or drydockings of vessels could have a material adverse effect on our ability to fulfill contract commitments and to realize timely revenues with respect to vessels under construction, conversion or other drydockings. Significant cost overruns or delays for vessels under construction could also adversely affect the company’s financial condition, results of operations or cash flows. The demand for vessels currently under construction may diminish from levels originally anticipated. If the company fails to obtain favorable contracts for newly constructed vessels, such failure could have a material adverse effect on the company’s revenues and profitability.

Also, difficult economic market conditions and/or prolonged distress in credit and capital markets may hamper the ability of shipyards to meet their scheduled deliveries of new vessels or the ability of the company to renew its fleet through new vessel construction or acquisitions. In addition, there is always the risk of insolvency of the shipyards that construct or drydock our vessels, which could adversely affect our new construction or repair programs, and consequently, adversely affect our financial condition, results of operations or cash flows.

Risks Associated with Operating Internationally

We operate in various regions throughout the world, which exposes us 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 (please refer to Item 7 in this report and Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report for a discussion of our Venezuelan operations regarding vessel seizures); foreign government regulations that favor or require the awarding of contracts to local competitors; an inability to recruit and retain management of overseas operations; difficulties in collecting accounts receivable and longer collection periods, changing taxation policies, fluctuations in currency exchange rates, revaluations, devaluations and restrictions on repatriation of currency; and import/export quotas and restrictions or other trade barriers - most of which are beyond the control of the company.

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

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.-owned companies such as ours. To date, the company has not experienced any material adverse effects on its results of operations and financial condition as a result of terrorism, political instability or war.

20

Risks Associated with Doing Business Through Joint Ventures

The company operates in several foreign areas through a joint venture with a local company, 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 inevitably 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 and 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 vessels in another area. The unwinding of an existing relationship 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 vessels to another area could adversely affect our financial condition, results of operations or cash flows.

International Operations Exposed to Currency Devaluation and Fluctuation Risk

Since we are 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 are incurred in local currencies and the company is at risk of changes in the exchange rates between the U.S. dollar and foreign currencies. 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 assets and liabilities denominated in currencies other than our functional currency 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, the company attempts to contract a significant majority of its services in U.S. dollars. In addition, the company attempts to minimize its financial impact of these risks, by matching the currency of the company’s operating costs with the currency of revenue streams when considered appropriate. The company continually monitors the currency exchange risks associated with all contracts not denominated in U.S. dollars.

Operational Hazards Inherent to the Offshore Marine Vessel Industry

The operation of any marine vessel involves inherent risk that could adversely affect our financial performance if we are not adequately insured or indemnified. Our operations are also subject to various operating hazards and risks, including risk of catastrophic marine disaster; adverse sea and weather conditions; mechanical failure; navigation errors; collisions and property losses to the vessel; damage to and loss of drilling rigs and production facilities; war, sabotage, pirate and terrorism risks; and business interruption due to political action or inaction, including nationalization of assets by foreign governments.

These risks present a threat to the safety of personnel and to our vessels, cargo, equipment under tow and other property, as well as the environment. Any such event may result in a reduction in revenues, increased costs, property damage, and additionally, third parties may have significant claims against us for damages due to personal injury, death, property damage, pollution and loss of business. We carry what we consider to be prudent levels of liability insurance and our vessels are generally insured for their estimated market value against damage or loss, including war, terrorism acts, and pollution risks, but the company does not fully insure for business interruption. Our insurance coverages are subject to deductibles and certain exclusions. We can provide no assurance, however, that our insurance coverages will be available beyond the renewal periods, that we will be able to obtain insurance for all operational risks and that our insurance policies will be adequate to cover future claims that may arise.

21

Compliance with the Foreign Corrupt Practices Act and Similar Worldwide Anti-Bribery Laws

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. In order to effectively compete in certain foreign jurisdictions, the company seeks to establish joint ventures with local operators or strategic partners. 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 our strategic or local partners or agents even though these partners or agents may not themselves be subject to the FCPA. Any determination that we have violated the FCPA (or any other applicable anti-bribery laws in countries in which the company does business) could have a material adverse effect on our business, results of operations, and cash flows. A discussion of the company’s FCPA internal investigation is disclosed in the “Completion of Internal Investigation and Settlements with United States and Nigerian Agencies” section of Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report.

Compliance with Complex and Developing Laws and Regulations

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 and the United States Customs and Border Protection and their foreign equivalents, and to regulation by private industry organizations such as the American Bureau of Shipping, the Oil Companies International Marine Forum, and the International Marine Contractors Association.

Our operations are also 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 the company to liability without regard to whether the company was negligent or at fault.

Further, many of the countries in which the company operates have laws, regulations and enforcement systems that are largely undeveloped, and the requirements of these systems are not always readily discernable even to experienced and proactive participants. Further, these laws, regulations and enforcement systems can be unpredictable and subject to frequent change or reinterpretation, sometimes with retroactive effect, and with associated taxes, fees, fines or penalties sought from the company based on that reinterpretation or retroactive effect. While the company endeavors to comply with applicable laws and regulations, the company’s 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 the company’s operations. These laws and regulations may expose the company 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 the company may not be able to pass along to its customers. Any changes in laws, regulations or standards that would impose additional requirements or restrictions could adversely affect the company’s financial condition, results of operations or cash flows.

In order to meet the continuing challenge of complying with applicable laws and regulations in jurisdictions where it operates, the company revitalized and strengthened its compliance training, makes available and uses a worldwide compliance reporting system and performs compliance auditing/monitoring. The company appointed its general counsel as its chief compliance officer in fiscal 2008 to help organize and lead these compliance efforts. This strengthened compliance program may from time to time identify past practices that need to be changed or remediated. Such corrective or remedial measures could involve significant expenditures or lead to changes in operational practices that could adversely affect the company’s financial condition, results of operations or cash flows.

We are subject to the Merchant Marine Act of 1936, which provides that, upon proclamation by the President of the United States of a national emergency or a threat to the security of the national defense, the Secretary of Transportation may requisition or purchase any vessel or other watercraft owned by U.S. citizens (including

22

U.S. corporations), including vessels under construction in the United States. If our vessels were purchased or requisitioned by the U.S. federal government, we would be entitled to be paid the fair market value of the vessels in the case of a purchase or, in the case of a requisition, the fair market value of charter hire, but we would not be entitled to be compensated for any consequential damages suffered. Although the purchase or requisition of one or a few of our vessels for an extended period of time will not cause adverse material negative financial effects to our company, the purchase or requisition of several or a significant number of our vessels for an extended period of time may adversely affect our financial condition, results of operations, and cash flows.

Risk of Changes in Laws Governing U.S. Taxation of Foreign Source Income

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 where we have lower statutory rates and higher than anticipated earnings in countries where we have higher statutory rates, or by changes in the valuation of our deferred tax assets and liabilities.

Over 90% of the company’s revenues and net income are generated by its operations outside of the United States. The company’s effective tax rate has averaged approximately 18.8% since fiscal 2006, primarily a result of the passage of The American Jobs Creation Act of 2004, which excluded from the company’s current taxable income in the U.S. income earned offshore through the company’s 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 the company’s international operations, it would result in a materially higher tax expense, which would have a material impact on the company’s financial condition, results of operations or cash flows, and which could cause the company to review the utility of continued U.S. domicile.

In addition, our income tax returns are subject to review and examination by the Internal Revenue Service and other tax authorities where tax returns are filed. The company routinely evaluates 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 are 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 adversely affected.

Compliance with Environmental Regulations May Adversely Impact Our Operations and Markets

A variety of regulatory developments, proposals and requirements have been introduced in the U.S. and various other countries that are focused on restricting the emission of carbon dioxide, methane and other gases. If such legislation is enacted, 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 curtail 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 the company’s offshore supply vessels, which are highly dependent on the level of activity in offshore oil and natural gas exploration, development and production market. Although it is unlikely that demand for oil and gas will lessen dramatically over the short-term, in the long-term, demand for oil and gas or increased regulation of environmental regulations may create greater incentives for use of alternative energy sources. Unless and until legislation is enacted and its terms are known, we cannot reasonably or reliably estimate its 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.

The Deepwater Horizon Incident and the Aftereffects of the Drilling Moratorium in the U.S. GOM Could Have a Material Impact on Exploration and Production Activities in United States Coastal Waters

The success and profitability of our operations in the United States are dependent on the level of upstream drilling and exploration activity in the U.S. GOM, and to a lesser extent on the West Coast of the United States and in Alaska. In particular, many of our new-build vessels were designed to operate in deep water off the continental shelf to assist in drilling and exploration efforts in that area. The margins we earn on our deepwater vessels have typically been higher than margins we achieve on other classes of our vessels. Although the BOEMRE is now issuing new drilling permits, the new regulations and requirements could suppress the level of drilling activity and demand for our services, which could have a material adverse effect on our U.S. operations which are part of our Americas segment. In addition, if exploration and production activity migrates from the U.S. GOM to international markets because of the these additional regulations and resulting increase in operating costs in the U.S. GOM, it is also possible that other offshore supply vessel owners will redeploy their respective vessels to international markets where we operate. These mobilizations would increase competition and thus could negatively affect our vessel utilization and day rates in international markets, depending on the number of drilling rigs that exit the U.S. GOM and move to international markets.

Also among the uncertainties that confront the industry are whether Congress will repeal the $75.0 million cap for non-reclamation liabilities under the Oil Pollution Act of 1990 and whether insurance will continue to be available at a reasonable cost and with reasonable policy limits to support drilling and exploration activity in the U.S. GOM. Although the eventual outcome of these developments is currently unknown, we believe that, even in the best case for the industry that we serve, additional regulatory and operational costs will be incurred, and these additional costs may either reduce the level of exploratory activity in the U.S. GOM, reduce demand for our services, or both.

ITEM 3.  LEGAL PROCEEDINGS

Shareholder Derivative Suit

In mid-February 2011, an individual claiming to be a Tidewater shareholder filed a shareholder derivative suit in the U.S. District Court for the Eastern District of Louisiana. The defendants in the suit are individual directors and certain officers of Tidewater Inc. Tidewater Inc. is also a nominal defendant in the lawsuit. The suit asserts various causes of action, including breach of fiduciary duty, against the individual defendants in connection with the facts and circumstances giving rise to the settlements with the DOJ and SEC and seeks a number of remedies against the individual defendants and the company as a result. For a discussion of the settlements with the DOJ and SEC regarding matters arising under the United States Foreign Corrupt Practices Act, refer to Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report. While the company will incur costs in connection with the defense of this law suit, the suit does not seek monetary damages against the company. The individual defendants and the company have retained legal counsel. The lawsuit is still in an early stage.

Other Items

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. Information related to various commitments and contingencies, including legal proceedings, is disclosed in Note (11) of Notes to Consolidated Financial Statements.

Issuer Repurchases of Equity Securities

On May 17, 2012, the company’s Board of Directors authorized the company to spend up to $200.0 million to repurchase shares of its common stock in open-market or privately-negotiated transactions. The effective date of this new authorization is July 1, 2012 through June 30, 2013. The company will use its available cash and, when considered advantageous, borrowings under its revolving credit facility or other borrowings, to fund any share repurchases.

In May 2011, the company’s Board of Directors replaced its then existing July 2009 share repurchase program with a new $200.0 million repurchase program that is in effect through June 30, 2012. The Board of Directors authorized the company to repurchase shares of its common stock in open-market or privately-negotiated transactions. The company uses its available cash and, when considered advantageous, borrowings under its revolving credit facility, or other borrowings, to fund any share repurchases. The company will evaluate share repurchase opportunities relative to other investment opportunities and in the context of current conditions in the credit and capital markets. At March 31, 2012, $165.0 million authorization remains available to repurchase shares under the May 2011 share repurchase program.

The company’s Board of Directors had previously authorized the company in July 2009 to repurchase up to $200.0 million in shares of its common stock in open-market or privately-negotiated transactions. The Board of Directors’ authorization for this repurchase program was replaced in May 2011 when the Board of Directors extended the program.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition and results of operations should be read in conjunction with the accompanying consolidated financial statements as of March 31, 2012 and 2011 and for the years ended March 31, 2012, 2011 and 2010 that we included in Item 8 of this Annual Report on Form 10-K. The following discussion and analysis contains forward-looking statements that involve risks and uncertainties. The company’s future results of operations could differ materially from its historical results or those anticipated in its forward-looking statements as a result of certain factors, including those set forth under “Risk Factors” in Item 1A and elsewhere in this report. With respect to this section, the cautionary language applicable to such forward-looking statements described in “Forward-Looking Statements” found before Item 1 of this report is incorporated by reference into this Item 7. The following discussion should also be read in conjunction with the Selected Financial Data and the Consolidated Financial Statements and related disclosures of this report.

Fiscal 2012 Business Highlights and Key Focus

During fiscal 2012 the company continued to focus on maintaining its competitive advantages and its market share in international markets, and continued to modernize its vessel fleet to increase future earnings capacity while removing from active service certain older, or traditional, vessels that currently have fewer market opportunities. Key elements of the company’s strategy continue to be the preservation of its strong financial position and the maintenance of adequate liquidity to fund the expansion of its fleet of newer vessels. Operating management focused on safe operations, minimizing unscheduled downtime, and maintaining disciplined cost control.

The company’s strategy contemplates the possible acquisitions of vessels and/or other owners and operators of offshore supply vessels as well as organic growth through the construction of vessels at a variety of shipyards worldwide. The company has the largest number of new vessels among its competitors in the industry, and it also has the largest fleet of older vessels in the industry. Management regularly evaluates alternatives for its older fleet. The company intends to pursue its long-term fleet replenishment and modernization strategy on a disciplined basis and, in each case, will carefully consider whether proposed investments and transactions have the appropriate risk/reward profile.

During the quarter ended September 30, 2011, our International and United States segments were revised to form four new operating segments. We now manage and measure our business performance in four distinct operating segments which are based on our geographical organization: Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The new segments are reflective of how the company’s chief operating decision maker reviews operating results for the purposes of allocating resources and assessing performance. Management decided to reorganize its reporting segments largely because the company’s Sub-Saharan Africa/Europe and Latin American business regions had gained greater significance as a percentage of consolidated revenues and operating profit, while our former United States segment had decreased in its significance to consolidated revenues and operating profit. Prior period disclosures have been recast to reflect the change in reportable segments.

Although the company’s revenue during fiscal 2012 increased $11.6 million, or a modest 1%, over the revenues earned during fiscal 2011, the company’s consolidated net earnings decreased 17%, or $18.2 million, during fiscal 2012, reflecting a $30.9 million non-cash goodwill impairment charge ($22.1 million after-tax, or $0.43 per share) recorded during the quarter ended September 30, 2011 on the company’s Middle East/North Africa segment as disclosed in Note (15) of Notes Consolidated Financial Statements included in Part I, Item 1 of this report, an $11.1 million, or 8%, increase in general and administrative expenses; and $11.5 million, or 107%, higher interest and debt costs as disclosed in Note (4) of Notes to Consolidated Financial Statements.

Partially offsetting the increase in these expenses was a $4.4 million, or 33%, increase in gain on asset dispositions, net, and a 44%, or $18.9 million, reduction in income taxes due to the expiration of statutes of limitations with respect to tax liabilities that had been established previously for uncertain tax positions as disclosed in Note (3) of Notes to Consolidated Financial Statements and due to lower earnings before income taxes. Other operating revenues increased approximately $2.4 million, or 57%, during the same comparative periods primarily because ship construction at the company’s shipyards increased during the current period.

28

In January 2011, the company amended and extended its then existing $450 million credit facility (the “previous facility”) and established $575 million in new credit facilities (the “new facilities”) for a five year period maturing January 2016. The new facilities include a $125 million term loan (“term loan”) and a $450 million revolving line of credit (“revolver”). The new facilities revolver and term loan borrowings bear interest at the company’s option at the greater of (i) prime or the federal funds rate plus 0.50 to 1.25%, or (ii) Eurodollar rates, plus margins between 1.50 to 2.25%, based on the company’s consolidated funded debt to total capitalization ratio. In January 2012, the company elected to draw on the entire $125 million term loan facility to fund working capital and for general corporate purposes. Principal repayments of any term loan borrowings are payable in quarterly installments beginning in the quarter ending September 30, 2013 in amounts equal to 1.25% of the total outstanding borrowings as of July 26, 2013.

On August 15, 2011, the company issued $165 million of senior unsecured notes to a group of institutional investors. The multiple series of notes were issued with maturities ranging from approximately eight to 10 years and have a weighted average life to maturity of approximately nine years. The weighted average coupon rate on the notes is 4.42%. The notes may be retired before their respective scheduled maturity dates subject only to a customary make-whole provision. The terms of the notes require that the company maintain a minimum ratio of debt to consolidated total capitalization that does not exceed 55%.

We continued our vessel construction and acquisition program during fiscal 2012 that had begun in calendar year 2000. This program facilitated the company’s entrance into deepwater markets around the world in addition to allowing the company to begin to replace its core towing supply/supply fleet with fewer, larger, and more technologically sophisticated vessels in order to meet our customers’ needs. The vessel construction and acquisition program was initiated with the intent of strengthening the company’s presence in all major oil and gas producing regions of the world through the replacement of aging vessels in the company’s core fleet. During this time, the company has purchased and/or constructed 238 vessels at a total cost of approximately $3.4 billion. Between April 1999 and March 2012, the company also sold, primarily to buyers that operate outside of our industry, 603 vessels. Most of the vessel sales were at prices that exceeded their carrying values. The vessel sales were accompanied by sales restrictions on competition or else the company determined that the prospects of the vessel competing with our ongoing business were low. In aggregate, proceeds from, and pre-tax gains on, vessel dispositions during this period approximated $650 million and $300 million, respectively.

In recent years, the company has generally funded vessel additions with operating cash flow, and funds provided by the July 2003 private placement of $300 million, the September 2010 private placement of $425 million, and the August 15, 2011 private placement of $165 million in senior unsecured notes, borrowings under its revolving credit facilities and $125 million bank term loan and various leasing arrangements.

At March 31, 2012, the company had agreements to acquire three vessels and commitments to build 22 vessels at a number of different shipyards around the world (with one of these vessels being constructed in the United States by the company’s wholly-owned shipyard, Quality Shipyards, L.L.C.) at a total cost, including contract costs and other incidental costs, of approximately $616.7 million. At March 31, 2012, the company had invested $244.5 million in progress payments towards the construction of 22 vessels and $12.9 million towards the purchase of three vessels. At March 31, 2012, the remaining expenditures necessary to complete construction of the 22 vessels currently under construction (based on contract prices) and to fund the acquisition of the three vessels was $359.3 million. A full discussion of the company’s capital commitments, scheduled delivery dates and vessel sales is disclosed in the “Vessel Count, Dispositions, Acquisitions and Construction Programs” section of Item 7 and Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report.

Macroeconomic Environment and Outlook

The primary driver of our business, and revenues, is the level of our customers’ capital and operating expenditures for oil and natural gas exploration, field development and production. These expenditures, in turn, generally reflect our customers’ expectations for future oil and natural gas prices, economic growth, hydrocarbon demand and estimates of current and future oil and natural gas production. The prices of crude oil and natural gas are critical factors in exploration and production (E&P) companies’ decisions to contract drilling rigs and offshore service vessels in the various international markets or the U.S. GOM, with the various international markets being largely driven by supply and demand for crude oil, and the U.S. GOM being

29

influenced both by the supply and demand for natural gas (primarily in regards to shallow water activity) and the supply and demand for crude oil (primarily in regards to deepwater activity).

During fiscal 2012, the price of crude oil increased as positive economic news related to consumer spending, improvements in employment data, and higher consumer confidence in the U.S. indicated that the tenuous economic recovery may not be losing its momentum in the U.S. In addition, crude oil prices increased during fiscal 2012 due to potential supply interruptions resulting from geopolitical tensions in the Middle East as Iran threatened to shut down the Strait of Hormuz in an effort to disrupt crude oil supplies as tension mounted between Iran and other nations regarding proposed sanctions related to Iran’s nuclear programs. Prices for crude oil, however, eased slightly as the Organization of Petroleum Exporting Companies (OPEC) announced that member nation Saudi Arabia and other OPEC member nations would be ready to provide additional oil supply in an effort to stabilize crude oil prices should a blockage in the Strait of Hormuz occur. Although signs of an improved economy in the U.S., the world’s largest consumer of crude oil, are promising, and OPEC, at its meeting held in December 2011 noted that global crude oil demand is forecast to improve in calendar year 2012, there is still some downside risks to the global economic recovery due to fiscal and financial uncertainty in certain Euro-zone countries, a prolonged level of relatively high unemployment in the U.S. and other advanced economies, and inflation risks in emerging economies. Based on these uncertainties, OPEC member nations agreed in December 2011 to maintain current crude oil production levels to ensure the supply and demand for crude oil is balanced. In addition, at the Middle East and North Africa 2012 Energy Conference held in late January 2012, OPEC further expressed that it will strive to meet consumer demand, crude oil market stability, and other coordinated efforts to ensure balanced global supply of crude oil at a time when, despite the economic uncertainties, long-term demand for crude oil is expected to grow. Tidewater anticipates that its longer-term utilization and day rate trends for its vessels will be correlated with demand for and the price of crude oil, which in late-April 2012, was trading around $105 per barrel for West Texas Intermediate (WTI) crude and around $120 per barrel for Intercontinental Exchange (ICE) Brent crude. High crude oil prices generally bode well for increases in drilling and exploration activity, which would support increases in demand for the company’s vessels, both in the various global markets and the deepwater sectors of the U.S. GOM (assuming the pace of permits continues to increase).

Throughout fiscal 2012, prices for natural gas were weak due to the rise in production of unconventional gas resources in North America (in part due to increases in onshore shale production resulting from technological advancements in horizontal drilling and hydraulic fracturing) and the commissioning of a number of new, large, Liquefied Natural Gas (LNG) exporting facilities around the world, which have contributed to an over supplied natural gas market. The price of natural gas trended lower during fiscal 2012 and as of mid-April 2012, natural gas was trading in the U.S. in the $1.85 to $2.05 per Mcf range down from the $4.13 to $4.32 range at the start of fiscal 2012. The price for natural gas trended lower as inventories for the resource trended higher because a considerable amount of natural gas is derived as a byproduct of drilling crude oil and natural gas liquids-oriented wells in liquid rich basins onshore. In addition, a relatively mild winter in North America and a slow start to winter in the Euro-Zone depressed weather-related demand for natural gas, thereby adding to supply growth. Natural gas inventories in the U.S. continue to be well over stocked. This dynamic exerts downward pricing pressures on natural gas prices in the U.S. Prolonged increases in the supply of natural gas (whether the supply comes from conventional or unconventional natural gas production or gas produced as a by product of crude oil production) will likely restrain prices for natural gas. Increases in onshore gas production along with a very slow offshore drilling and exploration permitting process in the U.S. GOM and prolonged downturn in natural gas prices can negatively impact the offshore exploration and development plans of E&P companies, which in turn, would result in a decrease in demand for offshore support vessel services, primarily in the Americas segment (specifically our U.S. operations where natural gas is the more predominant exploitable hydrocarbon resource).

Certain oil and gas industry analysts are reporting in their 2012 E&P expenditures (both land-based and offshore) surveys that global capital expenditure budgets for E&P companies are forecast to increase by at least 10% over calendar year 2011 levels. The surveys forecast that international capital spending budgets will increase approximately 11% while North American capital spending budgets are forecast to increase approximately 8%. It is anticipated by these analysts that the North American capital budget increases will primarily be spent onshore rather than offshore, while international E&P spending is expected to be largely offshore, with the strongest markets expected to include Latin America, Africa, Europe, Russia, and the Middle East. Capital expenditure budgets incorporated into the spending surveys were based on an approximate $87 WTI and $98 Brent average prices per barrel of oil. Although E&P companies are using an approximate

30

$4.08 per mcf average natural gas price for their 2012 capital budgets, natural gas directed drilling is forecast to decline due to weak natural gas prices.

Deepwater activity continues to be a significant segment of the global offshore crude oil and natural gas markets, and it is also a source of growth for the company. Deepwater activity in non-U.S. markets did not experience significant negative effects from the 2008-2009 global economic recession, largely because 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 assumptions relating to crude oil and natural gas prices. These projects are, therefore, considered less susceptible to short-term fluctuations in the price of crude oil and natural gas. During the past few years, worldwide rig construction increased as rig owners capitalized on the high worldwide demand for drilling and low shipyard and financing costs. Reports published by ODS-Petrodata in late April 2012 suggest that the worldwide movable drilling rig count (currently estimated at approximately 860 movable offshore rigs worldwide, approximately 44% of which are designed to operate in deeper waters) will increase as approximately 185 new-build offshore rigs that are currently on order and under construction are delivered primarily over the next three years. Of the estimated 860 movable offshore rigs worldwide, approximately 615 are currently working. It is further estimated that approximately 54% of the new build rigs are being built to operate in deeper waters, suggesting that the number of rigs designed to operate in deeper waters could grow in the coming years to nearly 50% of the market. Investment is also being made in the floating production unit market, with approximately 70 new floating production units currently under construction and expected to be delivered primarily over the next three years to supplement the current approximately 350 floating production units worldwide.

According to ODS-Petrodata, the global offshore supply vessel market at March 31, 2012 had approximately 410 new-build offshore support vessels (platform supply vessels and anchor handlers only), under construction that are expected to be delivered to the worldwide offshore vessel market primarily over the next three years. The current worldwide fleet of these classes of vessels is estimated at approximately 2,745 vessels, of which Tidewater estimates more than 10% are stacked.

An increase in worldwide vessel capacity would tend to have the effect of lowering charter rates, particularly when there are lower levels of exploration, field development and production activity. The worldwide offshore marine vessel industry, however, also has a large number of aged vessels including approximately 725 vessels, or 26%, 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, approximately one-third of which Tidewater estimates are already stacked, could potentially be removed from the market within the next few years if the cost of extending the vessels’ lives is not economically justifiable. Although the future attrition rate of these aging vessels cannot be determined with certainty, the company believes that the retirement of a sizeable portion of these aged vessels could mitigate the potential combined negative effects of new-build vessels on vessel utilization and vessel pricing. Additional vessel demand could also be created by the addition of new drilling rigs and floating production units that are expected to be delivered and become operational over the next few years, which should help minimize the possible negative effects of the new-build offshore support vessels being added to the offshore support vessel fleet.

Principal Factors That Drive Our Revenues

The company’s revenues, net earnings and cash flows from operations are largely dependent upon the activity level of its offshore marine vessel fleet. As is the case with many other energy service companies, our business activity is largely dependent on the level of drilling and exploration activity of 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. In addition, after the Deepwater Horizon incident in April 2010, the level of drilling activity off the continental shelf of the United States (U.S.) Gulf Of Mexico (GOM) declined while the U.S. government evaluated the causes of the incident and announced a plan for enhanced regulatory and safety oversight as a condition to granting additional drilling and exploration permits.

The company’s revenues in all segments are driven primarily by the company’s fleet size, vessel utilization and day rates. Because a sizeable portion of the company’s operating costs and its depreciation does not change proportionally with changes in revenue, the company’s operating profit is largely dependent on revenue levels.

31

Principal Factors That Drive Our Operating Costs

Operating costs consist primarily of crew costs, repair and maintenance, insurance and loss reserves, fuel, lube oil and supplies and vessel operating lease expense.

Fleet size, fleet composition, geographic areas of operation, supply and demand for marine personnel, and local labor requirements are the major factors which affect overall crew costs in all segments. In addition, the company’s newer, more technologically sophisticated anchor handling towing supply vessels and platform supply vessels generally require a greater number of specially trained, more highly compensated fleet personnel than the company’s older, smaller and less sophisticated vessels. The company believes that competition for skilled crew personnel may intensify as new-build support vessels currently under construction increase the number of offshore vessels operating worldwide. If competition for personnel intensifies, the company’s crew costs will likely increase.

The timing and amount of repair and maintenance costs are influenced by customer demand, vessel age and drydockings mandated by regulatory agencies. A certain number of periodic drydockings are required to meet regulatory requirements. The company will generally incur drydocking costs only if economically justified, taking into consideration the vessel’s age, physical condition, contractual obligations, current customer requirements and future marketability. When the company elects to forego a required drydocking, it stacks and occasionally sells the vessel because it is not permitted to work without valid regulatory certifications. When the company drydocks a productive vessel, the company not only foregoes vessel revenues and incurs drydocking costs, but also continues to incur vessel operating and depreciation costs. In any given period, vessel downtime associated with drydockings and major repairs and maintenance can have a significant effect on the company’s revenues and operating costs.

At times, vessel drydockings take on an increased significance to the company and its financial performance. Older vessels may require more frequent and more expensive repairs and drydockings. Newer vessels (generally those built after 2000), which now account for a majority of the company’s revenues and vessel margin (vessel revenues less vessel operating costs), can also require expensive drydockings, even in the early years of a vessel’s useful life, due to the larger relative size and greater relative complexity of these vessels. Conversely, when the company stacks vessels, the number of drydockings in any period could decline. The combination of these factors can affect drydock costs, which are primarily included in repair and maintenance expense, and incrementally increase the volatility of the company’s revenues and operating income, thus making period-to-period comparisons more difficult.

Although the company attempts to efficiently manage its fleet drydocking schedule, changes in the demand for (and supply of) shipyard services can result in heavy workloads at shipyards and inflationary pressure on shipyard pricing. In recent years, increases in drydocking costs and days off hire (due to vessels being drydocked) have contributed to volatility in repair and maintenance costs and vessel revenue. In addition, some of the more recently constructed vessels are now experiencing their first or second required regulatory drydockings.

Insurance and loss reserves costs are dependent on a variety of factors, including the company’s safety record and pricing in the insurance markets, and can fluctuate over time. The company’s vessels are generally insured for up to their estimated fair market value in order to cover damage or loss resulting from marine casualties, adverse weather conditions, mechanical failure, collisions, and property losses to the vessel. The company also purchases coverage for potential liabilities stemming from third-party losses with limits that it believes are reasonable for its operations. Insurance limits are reviewed annually and third-party coverage is purchased based on the expected scope of ongoing operations and the cost of third-party coverage.

Fuel and lube costs can also fluctuate in any given period depending on the number and distance of vessel mobilizations, the number of active vessels off charter, drydockings, and changes in fuel prices.

The company also incurs vessel operating costs that are aggregated as “other” vessel operating costs. These costs consist of brokers’ commissions, training costs and other miscellaneous costs. Brokers’ commissions are incurred primarily in the company’s non-United States operations where brokers sometimes assist in obtaining work for the company’s vessels. Brokers generally are paid a percentage of day rates and, accordingly, commissions paid to brokers generally fluctuate in accordance with vessel revenue. Other costs include, but

32

are not limited to, satellite communication fees, agent fees, port fees, canal transit fees, vessel certification fees, temporary vessel importation fees and any fines or penalties.

Results of Operations

During the quarter ended September 30, 2011, our International and United States segments were reorganized to form four new operating segments. We now manage and measure our business performance in four distinct operating segments which are based on our geographical organization: Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The following table compares vessel revenues and vessel operating costs (excluding general and administrative expenses, depreciation expense, provision for Venezuelan operations, goodwill impairment, and gains on asset dispositions) for the company’s vessel fleet and the related percentage of vessel revenue for the years ended March 31. Vessel revenues and operating costs relate to vessels owned and operated by the company.

Fiscal 2012 Compared to Fiscal 2011

Consolidated Results.    Although the company’s revenue during fiscal 2012 increased $11.6 million, or a modest 1%, over the revenues earned during fiscal 2011, the company’s consolidated net earnings decreased 17%, or $18.2 million, during fiscal 2012, reflecting a $30.9 million non-cash goodwill impairment charge ($22.1 million after-tax, or $0.43 per share) recorded during the quarter ended September 30, 2011 on the

34

company’s Middle East/North Africa segment as disclosed in Note (15) of Notes Consolidated Financial Statements included in Part I, Item 1 of this report, an $11.5 million, or 107%, increase in interest and debt costs as disclosed in Note (4) of Notes Consolidated Financial Statements; and an $11.1 million, or 8%, increase in general and administrative expenses.

Partially offsetting the increase in these expenses was a $4.4 million, or 33%, increase in gain on asset dispositions, net, and a 44%, or $18.9 million, reduction in income taxes due to the expiration of statutes of limitations with respect to tax liabilities that had been previously established for uncertain tax positions (as disclosed in Note (3) of Notes to Consolidated Financial Statements) and lower earnings before income taxes. Other operating revenues increased approximately $2.4 million, or 57%, during the same comparative periods primarily because activity at the company’s shipyards increased during the current period.

Vessel operating costs during fiscal 2012 were comparable to those in fiscal 2011. Crew costs decreased approximately 3%, or $10.4 million, during fiscal 2012 as compared to fiscal 2011, primarily because the prior fiscal year included a $6.0 million charge associated with the company’s participation in the Merchant Navy Officers Pension Fund (MNOPF) as disclosed in Note (11) of Notes to Consolidated Financial Statements. Repair and maintenance costs decreased 7%, or $7.2 million, during fiscal 2012, because a greater number of drydockings were performed during fiscal year 2011. In particular, during fiscal 2011, we performed four scheduled drydockings of our largest anchor handling towing supply vessels for an aggregate cost of $14.5 million. Fuel, lube and supply costs increased 24%, or $15.1 million, during fiscal 2012 as compared to fiscal 2011, primarily due to the mobilization of newly delivered vessels and because of vessel mobilizations between operating areas. Costs of other operating revenues increased $2.5 million, or 53%, during the same comparative periods primarily because ship construction activity at the company’s shipyards increased during fiscal 2012.

At March 31, 2012, the company had 330 owned or chartered vessels (excluding joint-venture vessels and vessels withdrawn from service) in its fleet with an average age of 14 years. The average age of 215 newer vessels in the fleet (defined as those that have been acquired or constructed since calendar year 2000 as part of the company’s new build and acquisition program) is 5.7 years. The remaining 115 vessels have an average age of 29.6 years. During fiscal 2012 and 2011, the company’s newer vessels generated $911.5 million and $838.5 million, respectively, of consolidated revenue and accounted for 86%, or $386.1 million, and 80%, or $363.9 million, respectively, of total vessel margin (vessel revenues less vessel operating costs). Vessel operating costs exclude depreciation on the company’s new vessels of $111.6 million and $97.9 million, respectively, during the same comparative periods.

Americas Segment Operations.    Americas-based vessel revenues decreased approximately 11%, or $38.3 million, during fiscal 2012 as compared to fiscal 2011, primarily due to an approximate 6% decrease in average day rates on the deepwater vessels operating in the Americas and because a fewer number of vessels are operating in this segment after the transfer of deepwater vessels to other segments. Revenues on the deepwater vessels declined 19%, or $34.3 million, during the comparative periods. In addition, revenues on our towing supply/supply class of vessels also declined $5.4 million, or 4%, during the same comparative periods primarily due to a fewer number of vessels operating after vessel sales. A $1.9 million, or 8%, increase in revenues generated by offshore tugs, during the same comparative periods, slightly offset revenue declines on the two aforementioned classes of vessels due to an eight percentage point increase in utilization and a 29% increase in average day rates due to stronger demand for this type of vessel in the Americas segment.

Total utilization rates for the Americas-based vessels increased seven percentage points, during fiscal 2012 as compared to fiscal 2011; however, this increase is primarily a result of the sale of 50 older, stacked vessels from the Americas fleet during this two-year period. Vessel utilization rates are calculated by dividing the number of days a vessel works by the number of days the vessel is available to work. As such, stacked vessels depressed utilization rates during the comparative periods because stacked vessels are considered available to work, and as such, are included in the calculation of utilization rates. Within the Americas segment, the company continued to stack, and in some cases dispose of, vessels that could not find attractive charters. At the beginning of fiscal 2012, the company had 39 Americas-based stacked vessels. During fiscal 2012, the company stacked six additional vessels and sold 24 vessels from the previously stacked vessel fleet, resulting in a total of 21 stacked Americas-based vessels as of March 31, 2012.

35

Vessel operating profit for the Americas-based vessels increased approximately 14%, or $6.7 million, during fiscal 2012 as compared to fiscal 2011, despite a decrease in revenues during the comparative periods, because of a 17%, or $38.1 million, decrease in vessel operating costs (primarily crew costs, repair and maintenance costs, and other vessel costs) and a decrease in depreciation expense, both of which offset the decline in revenues.

Depreciation expense decreased approximately 16%, or $7.3 million, during fiscal 2012 as compared to fiscal 2011, because of the transfer of vessels to other segments and because of vessel sales. Crew costs decreased 12%, or $15.6 million, during the same comparative periods, due to reductions in crew personnel at our U.S. GOM operations as a result of fewer vessels operating in the U.S. GOM market due to the continued aftereffects of the drilling moratorium, and because the prior year’s non-U.S. Americas operations included an allocated $2.1 million charge associated with the company’s participation in the Merchant Navy Officers Pension Fund (MNOPF) as disclosed in Note (11) of Notes to Consolidated Financial Statements. Repair and maintenance costs decreased approximately 37%, or $18.1 million, from the prior fiscal year, due to a fewer number of drydockings being performed during the current periods and because in the prior fiscal year we performed three scheduled drydockings of our largest anchor handling towing supply vessels (for an aggregate cost of $11.1 million).

Asia/Pacific Segment Operations.    Asia/Pacific-based vessel revenues decreased approximately 13%, or $23.1 million, during fiscal 2012 as compared to fiscal 2011, primarily due to a five percentage point decrease in utilization rates on the towing supply/supply class of vessels as a result of weaker demand, particularly for older equipment within this class of vessels and because of vessels transferred out of the segment, which collectively resulted in a $15.7 million decrease in vessel revenues on the Asia/Pacific region’s non-deepwater towing supply/supply class of vessels. Revenues on the deepwater vessels also declined $7.4 million due to a two percentage point decrease in utilization rates on the deepwater vessels operating in this segment, largely due to unanticipated delays on certain customer projects.

Within the Asia/Pacific segment, the company also continued to stack, and in some cases dispose of, vessels that could not find attractive charters. At the beginning of fiscal 2012, the company had 19 Asia/Pacific-based stacked vessels. During fiscal 2012, the company stacked three additional vessels and sold six vessels from the previously stacked vessel fleet, resulting in a total of 16 stacked Asia/Pacific-based vessels as of March 31, 2012.

Asia/Pacific-based vessel operating profit decreased $6.2 million, or 28%, during fiscal 2012 as compared to fiscal 2011, primarily due to lower revenues and higher general and administrative expenses. Declines in revenues were partially offset by an approximate 14%, or $16.4 million, decrease in vessel operating costs (primarily crew costs, repair and maintenance costs, and fuel, lube and supply costs) and also due to a decrease in depreciation expense during the same comparative periods.

Crew costs decreased approximately 14%, or $10.0 million, during fiscal 2012 as compared to fiscal 2011, due to reductions in crew personnel related to the transfer of deepwater vessels to other segments. Crew costs also decreased because the prior year included an allocated $1.0 million charge associated with the company’s participation in the Merchant Navy Officers Pension Fund (MNOPF) as disclosed in Note (11) of Notes to Consolidated Financial Statements. Depreciation expense decreased 18%, or $4.7 million, from the prior fiscal year, due to the transfer of deepwater vessels to other segments and because of vessel sales.

General and administrative expenses increased 33%, or $4.2 million, during fiscal 2012 as compared to fiscal 2011, due to pay raises for the administrative personnel, an increase in office and property costs, and an increase in costs associated with foreign assigned administrative employees (specifically foreign income taxes paid by the company on behalf of expatriate employees). Repair and maintenance costs decreased approximately 21%, or $3.4 million, from the prior fiscal year, due to a fewer number of drydockings being performed during the current periods.

Middle East/North Africa Segment Operations.    Middle East/North Africa-based vessel revenues increased approximately 19%, or $17.3 million, during fiscal 2012 as compared to fiscal 2011, primarily due to a five percentage point increase in utilization rates on the deepwater vessels operating in this segment. This resulted in an $18.1 million increase in deepwater vessel revenues and reflects three deepwater vessels being transferred into the region from other segments during the comparative periods.

36

As was the case with other segments, within the Middle East/North Africa segment, the company continued to stack, and in some cases dispose of vessels that could not find attractive charters. At the beginning of fiscal 2012, the company had six Middle East/North Africa-based stacked vessels. During fiscal 2012, the company stacked seven additional vessels and sold six vessels from the previously stacked vessel fleet, resulting in a total of seven stacked Middle East/North Africa-based vessels as of March 31, 2012.

Middle East/North Africa-based vessel operating profit decreased approximately $18.2 million, or 96%, during fiscal 2012 as compared to fiscal 2011, which primarily reflects the scaling up of operations in the Middle East/North Africa segment in anticipation of a greater level of business activity. In particular, vessel operating costs increased 57%, or $28.6 million, (primarily crew costs, repair and maintenance costs, fuel, lube and supply costs, and vessel operating leases). In addition, depreciation expense increased approximately 23%, or $3.3 million, during the same comparative periods, and general and administrative expenses increased approximately $3.6 million, or 44%, during the same comparative periods.

Crew costs increased approximately 40%, or $10.1 million, during fiscal 2012 as compared to fiscal 2011, due to an increase in crew personnel related to the addition of vessels to the segment. Repair and maintenance costs increased approximately $7.3 million, or 80%, from the prior fiscal year, largely because the average cost of the drydockings performed during the current periods was higher. Depreciation expense increased, during the same comparative periods, primarily because of the additional vessels transferred to the segment related to the build-up of operations in anticipation of a greater level of business activity. General and administrative expenses increased, from the prior fiscal year, due to an increase in administrative personnel which resulted in higher administrative payroll, an increase in office and property costs, and an increase in costs associated with foreign assigned administrative employees also resulting from the build-up of operations in anticipation of a greater level of business activity.

Fuel, lube and supply costs increased approximately $4.9 million, or 59%, during fiscal 2012 as compared to fiscal 2011, due to an increase in the number of vessels operating in the segment resulting from new vessel deliveries and because of vessels mobilizing into this segment. Vessel operating leases increased approximately $1.9 million, from the prior fiscal year, because two vessels operating under lease arrangements were transferred into the segment.

Sub-Saharan Africa/Europe Segment Operations. Sub-Saharan Africa/Europe-based vessel revenues increased approximately 13%, or $53.3 million, during fiscal 2012 as compared to fiscal 2011, due to an increase in the number of deepwater vessels operating in the segment (due to the delivery of new vessels and vessels mobilizing into this segment), a three percentage point increase in utilization rates, and a 12% increase in average day rates on the deepwater vessels, all of which resulted in a $76.0 million increase in deepwater vessel revenues. Revenue increases generated by the deepwater vessels were partially offset by a decline in revenue experienced by the non-deepwater towing supply/supply class of vessels. Vessel revenue on the towing supply/supply class of vessels decreased approximately 9%, or $20.1 million, from the prior fiscal year, due to a five percentage point decrease in utilization rates and because fewer towing supply/supply class of vessels operated in the segment due to vessel sales and transfers to other segments.

Within the Sub-Saharan Africa/Europe segment, the company continued to stack, and in some cases dispose of vessels that could not find attractive charters. At the beginning of fiscal 2012, the company had 26 Sub-Saharan Africa/Europe-based stacked vessels. During fiscal 2012, the company stacked eight additional vessels and sold 11 vessels from the previously stacked vessel fleet, resulting in a total of 23 stacked Sub-Saharan Africa/Europe-based vessels as of March 31, 2012.

Sub-Saharan Africa/Europe-based vessel operating profit increased approximately 17%, or $14.1 million, during fiscal 2012 as compared to fiscal 2011, primarily due to higher revenues, which were partially offset by an approximate 10%, or $25.5 million, increase in vessel operating costs (primarily crew costs, repair and maintenance costs, and fuel, lube and supply costs); an increase in depreciation expense; and an increase in general and administrative expenses.

Crew costs increased approximately 5%, or $5.2 million, during fiscal 2012 as compared to fiscal 2011, respectively, due to an increase in crew personnel resulting from an increase in the number of deepwater vessels operating in the segment. Repair and maintenance costs, increased approximately 20%, or $7.0 million, from the prior fiscal year, due to a higher number of drydockings being performed during current

37

periods. Fuel, lube and supplies were higher by approximately 39%, or $9.0 million, during the same comparative periods, due to vessel mobilizations.

Depreciation expense increased approximately 10%, or $5.7 million, during fiscal 2012 as compared to fiscal 2011, primarily because of an increased number of vessels operating in the segment resulting from new vessel deliveries and vessels mobilizing into the segment during the current fiscal year. General and administrative expenses increased 21%, or $8.5 million, respectively, from the prior fiscal year, due to pay raises for the administrative personnel, an increase in office and property costs (primarily office rent and information technology costs), an increase in travel costs, and an increase in costs associated with foreign assigned administrative employees.

Other Items.    Insurance and loss reserves expense decreased $2.1 million, or 11%, during fiscal 2012 as compared to fiscal 2011, due to lower premiums and favorable adjustments to loss reserves during fiscal 2012 resulting from good safety results and loss management efforts.

Gain on asset dispositions, net during fiscal 2012 increased $4.4 million, or 33%, as compared to fiscal 2011, primarily due to lower impairment expense charged during the current fiscal year. Dispositions of vessels can vary from quarter to quarter; therefore, gains on sales of assets may fluctuate significantly from period to period.

The company performed a review of all its assets for asset impairment during fiscal 2012. The below table summarizes the combined fair value of the assets that incurred impairments along with the amount of impairment during the years ended March 31. The impairment charges were recorded in gain on asset dispositions, net.

(In thousands)	2012		2011
Amount of impairment incurred	$	3,607		8,958
Combined fair value of assets incurring impairment		8,175		13,646

Fiscal 2011 Compared to Fiscal 2010

Consolidated Results.    The company’s consolidated net earnings during fiscal 2011 decreased 59%, or $153.9 million, as compared to fiscal 2010, due primarily to an approximate 10%, or $113.2 million, decrease in total revenues, a $33.3 million, or 6%, increase in vessel operating costs, and a $34.2 million, or 414%, increase in income taxes during the comparative periods as disclosed in Note (3) of Notes to Consolidated Financial Statements included in Item 8 of this report.

During fiscal 2011 vessel utilization rates decreased approximately four percentage points as compared to fiscal 2010 due principally to reduced demand for the company’s older vessels by our customers. E&P customers reduced their capital spending budgets in response to lower hydrocarbon demand and weaker commodity prices precipitated by the 2008-2009 global economic recession. The 2008-2009 global recession resulted in a decrease in demand for offshore support vessel services worldwide. This reduced demand has led to an industry-wide reduction in charter rates and utilization rates on vessels as our customers needed fewer vessels and demanded pricing concessions.

The company recorded $1.1 billion in revenues during fiscal 2011 as compared to $1.2 billion in fiscal 2010, a decrease of approximately $113.2 million, primarily due to an approximate four percentage point reduction in total worldwide utilization and a decrease in the company’s shipyard activity for unaffiliated customers. In part, the decline in revenues reflected the vessel seizures in Venezuela in mid-2009 with fiscal 2010 including $11.3 million of revenues that were generated by the company’s Venezuelan operations. Other operating revenues decreased approximately $26.3 million, or 86%, during the same comparative periods primarily because ship construction at the company’s shipyards was completed on several projects and the shipyard has not been able to secure additional backlog.

Vessel operating costs increased 6%, or $33.3 million, during fiscal 2011 as compared to fiscal 2010. Crew costs increased approximately 6%, or $17.9 million, during fiscal 2011 as compared to fiscal 2010, because of the addition of 29 new vessels to the worldwide fleet. The newer, more technologically sophisticated vessels generally require a greater number of specially trained fleet personnel than the older, traditional vessels. In addition, crew costs increased during the same comparative periods, in part, due to a $6.0 million charge

38

associated with the company’s participation in the Merchant Navy Officers Pension Fund (MNOPF) as disclosed in Note (11) of Notes to Consolidated Financial Statements. Repair and maintenance costs also increased approximately 6%, or $6.1 million, during the same comparative periods, because a greater number of drydockings were performed during fiscal year 2011. In particular, during fiscal 2011, we performed four scheduled drydockings of our largest anchor handling towing supply vessels (for an aggregate cost of $14.5 million) as compared to one drydocking being performed on the same class of vessel during fiscal 2010 for a total cost of $3.3 million. Vessel operating lease costs increased approximately $2.9 million, or 19%, during fiscal 2011 because the company entered into six additional vessel operating leases during fiscal 2010, as disclosed in Note (10) of Notes to Consolidated Financial Statements and in the “Off-Balance Sheet Arrangements” section of this report. Fuel, lube and supply costs were higher by approximately 9%, or $5.1 million, during fiscal 2011 as compared to fiscal 2010, due to vessel mobilizations on the company’s newly delivered vessels and because of vessel transfers. Insurance and loss reserves increased approximately $6.6 million due to an increase in the number of vessels operating and due to unfavorable development of losses during fiscal 2011. Costs of other operating revenues decreased approximately $22.7 million, or 83%, during the same comparative periods because ship construction at the company’s shipyards was completed on several projects and the shipyard has not been able to secure additional backlog.

At March 31, 2011, the company had 364 owned or chartered vessels (excluding joint-venture vessels and vessels withdrawn from service) in its fleet with an average age of 16.5 years. The average age of 193 newer vessels in the fleet at March 31, 2011 (defined as those that have been acquired or constructed since calendar year 2000 as part of the company’s new build and acquisition program) was 5.4 years. The remaining 171 vessels had an average age of 29.0 years. During fiscal 2011 and 2010, the company’s newer vessels generated $838.5 million and $770.5 million, respectively, of consolidated revenue and accounted for 88%, or $363.9 million, and 74%, or $395.3 million, respectively, of total vessel margin (vessel revenues less vessel operating cost). Vessel operating costs exclude depreciation on the company’s new vessels of $97.9 million and $76.2 million, respectively, during the same comparative periods.

Americas Segment Operations.    Vessel revenues in the Americas segment decreased approximately 8%, or $30.4 million, during fiscal 2011 as compared to fiscal 2010, primarily due to a six percentage point decrease in utilization rates on the towing supply/supply class of vessels operating in the Americas (which resulted in a $20.8 million decline in revenue) mostly due to vessel sales, the transfer of vessels to other segments and weaker demand for this class of vessel (particularly the older towing supply/supply vessels). In addition, revenues in the Americas decreased during fiscal 2011 because of the loss of revenue resulting from the seizure of its Venezuelan operations (including the seizure of 15 vessels) as disclosed in Note (11) of Notes to Consolidated Financial Statements. Our Venezuelan operations contributed no revenues during fiscal 2011 as compared to $11.3 million of revenues contributed during fiscal 2010.

Within the Americas segment, the company stacked and disposed of a number of vessels that could not find attractive charters. At the beginning of fiscal 2011, the company had 48 Americas-based stacked vessels. During fiscal 2011, the company stacked 22 additional vessels, sold 26 vessels from the previously stacked vessel fleet, and returned to service five vessels resulting in a total of 39 stacked Americas-based vessels as of March 31, 2011.

Vessel operating profit for the Americas-based vessels increased approximately 32%, or $11.8 million, because fiscal 2010 vessel operating profit includes a $43.7 million provision for Venezuelan operations as disclosed in Note (11) of Notes to Consolidated Financial Statements. Excluding the Venezuelan provision from the comparatives, vessel operating profit for the Americas-based vessels decreased approximately 39%, or $31.9 million, primarily due to lower revenues in fiscal 2011 as compared to fiscal 2010 and due to a 2%, or $4.0 million, increase in vessel operating costs (primarily repair and maintenance costs and other vessel costs partially offset by lower crew costs and fuel, lube and supply costs) partially offset by a decrease in depreciation expense.

Repair and maintenance costs increased approximately 17%, or $7.3 million, during fiscal 2011 as compared to fiscal 2010 due to a greater number of drydockings being performed during the current fiscal year. In particular, during fiscal 2011, we performed three scheduled drydockings of our largest anchor handling towing supply vessels (for an aggregate cost of $11.1 million) as compared to one drydocking being performed on the same class of vessel during fiscal 2010 for a total cost of $3.3 million. Other vessel costs increased 27%, or $5.2 million, due primarily to the movement of several older vessels out of Brazil after the charters for these vessels had been completed. A number of these vessels were subsequently disposed of.

39

Depreciation expense decreased approximately 3%, or $1.4 million, during fiscal 2011 as compared to fiscal 2010 because of the transfer of vessels to other segments and because of vessel sales. Crew costs decreased approximately 5%, or $6.6 million, during the same comparative periods, primarily due to fewer vessels operating in the Americas because of vessel sales, vessel transfers to other segments, and the seizure of our Venezuelan fleet of 15 vessels. In addition, crew costs were lower during the comparative periods in the Americas due to the mobilization of two deepwater vessels from the U.S. GOM to other segments (because vessel demand related to the Deepwater Horizon oil spill containment effort had declined significantly) and because of wage reductions for remaining personnel operating in the U.S. GOM. Fuel, lube and supply costs decreased approximately 14%, or $2.4 million, during the same comparative periods because we had a fewer number of newly delivered vessels mobilize into the Americas and a fewer number of intersegment mobilizations.

Asia/Pacific Segment Operations.    Asia/Pacific-based vessel revenues increased approximately 4%, or $6.5 million, during fiscal 2011 as compared to fiscal 2010, primarily due to an approximate 10% increase in average day rates and a two percentage point increase in utilization rates on our deepwater vessels along with an increase in the number of deepwater vessels operating in Asia/Pacific segment following the addition of newly-built and acquired deepwater vessels and the transfer of deepwater class vessels from other segments, which collectively resulted in a $38.1 million increase in revenue on this class of vessels. Revenue declines on our non-deepwater towing supply/supply class of vessels partially offset the revenues earned on the deepwater class vessels. Revenues on the towing supply/supply vessels declined $34.3 million, or 28%, during the same comparative periods, due to a 23 percentage point decrease in utilization rates as a result of weaker demand for this class of vessel (specifically the older vessels in this class) despite a 9% increase in average day rates on this class of vessel.

In fiscal 2011, the company stacked, and in a number of cases disposed of, Asia/Pacific-based vessels that could not find attractive charters. At the beginning of fiscal 2011, the company had 12 Asia/Pacific-based stacked vessels. During fiscal 2011, the company stacked 14 additional vessels and sold seven vessels from the previously stacked vessel fleet, resulting in a total of 19 stacked Asia/Pacific-based vessels as of March 31, 2011.

Asia/Pacific-based vessel operating profit decreased approximately $26.7 million, or 55%, during fiscal 2011 as compared to fiscal 2010, primarily due to higher vessel operating costs, depreciation expense and general and administrative costs (despite an increase in revenues). Vessel operating costs increased 35%, or $30.2 million, during the same comparative periods (primarily crew costs, repair and maintenance costs, and fuel, lube and supply costs). Depreciation expense increased 7%, or $1.6 million, during the same comparative periods, due to an increase in the number of vessels operating in the segment as a result of vessel transfers and the delivery of newly built vessels. General and administrative expenses increased approximately 13%, or $1.4 million, during the same comparative periods, due to pay raises for the administrative personnel and temporary personnel staffing, an increase in office and property costs, and general increases caused by the devaluation of the U.S. dollar relative to the Australian dollar.

Crew costs increased approximately 39%, or $19.9 million, during fiscal 2011 as compared to fiscal 2010, due to an increase in crew personnel related to the transfer of vessels into the segments and because of an allocated $1.0 million charge associated with the company’s participation in the Merchant Navy Officers Pension Fund (MNOPF) as disclosed in Note (11) of Notes to Consolidated Financial Statements. Repair and maintenance costs increased 45%, or $5.1 million, during the same comparative periods due to a greater number of drydockings being performed during fiscal 2011 including a previously scheduled drydocking on one of our largest anchor handling towing supply vessels for a cost of $3.4 million. Fuel, lube and supply costs were higher by approximately 2%, or $2.3 million, during fiscal 2011 as compared to fiscal 2010, because of newly-constructed and acquired vessels that were added to the Asia/Pacific fleet, intersegment vessel mobilizations, and vessels mobilizing into the segment from other regions.

40

Middle East/North Africa Segment Operations.    Middle East/North Africa vessel revenues in fiscal 2011 were comparable to the revenues earned during fiscal 2010. However, revenues on our towing supply/supply vessels increased 5%, or $22.8 million, due to an increase in the number of towing supply/supply vessels operating in this segment, while a decrease in revenues generated by our offshore tugs almost offset the revenue gains achieved by the towing supply/supply class of vessels. In particular, revenues generated by the offshore tugs declined approximately 28%, or $2.6 million, due to a seven percentage point decrease in utilization and a 20% decrease in average day rates due to market weakness on this class of vessel.

Within the middle East/North Africa segment, the company also stacked and disposed of a number of vessels that could not find attractive charters. At the beginning of fiscal 2011, the company had three Middle East/North Africa -based stacked vessels. During fiscal 2011, the company stacked six additional vessels, sold two vessels from the previously stacked vessel fleet, and returned to service one vessel resulting in a total of six stacked Middle East/North Africa -based vessels as of March 31, 2011.

Middle East/North Africa-based vessel operating profit decreased $10.9 million, or 37%, during fiscal 2011 as compared to fiscal 2010 due primarily to a 15%, or $6.7 million, increase in vessel operating costs (primarily crew costs and fuel, lube and supply costs) and a 27%, or $3.0 million, increase in depreciation expense primarily because of the addition of approximately 10 newly delivered vessels and due to vessels mobilizing into the segment from other segments. Crew costs increased $2.9 million, or 13%, because of an increase in crew personnel resulting from an increase in the number of vessels operating in the segment. Fuel, lube and supply costs increased because newly delivered vessels were mobilized into the segment and due to vessels mobilizing into the segment from other segments.

Sub-Saharan Africa/Europe Segment Operations.    Sub-Saharan Africa/Europe-based vessel revenues decreased approximately 13%, or $61.8 million, during fiscal 2011 as compared to fiscal 2010, primarily due to a 10 percentage point decrease in utilization rates and a 14% decrease in average day rates on the towing supply/supply class of vessels resulting in a $74.5 million, or 25%, decline in revenue on this class of vessels, largely due to weak demand for this vessel class (particularly the older vessels). The decline in the towing supply/supply class of vessel revenues was partially offset by a 12%, or $13.2 million, increase in revenue earned by the deepwater vessels due to the addition of 16 deepwater vessels throughout fiscal 2010 and fiscal 2011 following the addition of newly-built and acquired deepwater vessels to the Sub-Saharan Africa/Europe-based fleet and the transfer of deepwater class vessels from other segments.

The company continued to stack and dispose of Sub-Saharan Africa/Europe-based vessels that could not find attractive charters. At the beginning of fiscal 2011, the company had 20 Sub-Saharan Africa/Europe-based stacked vessels. During fiscal 2011, the company stacked 12 additional vessels and sold six vessels from the previously stacked vessel fleet, resulting in a total of 26 stacked Sub-Saharan Africa/Europe-based vessels as of March 31, 2011.

Sub-Saharan Africa/Europe-based vessel operating profit decreased approximately 43%, or $62.0 million, during fiscal 2011 as compared to fiscal 2010, because of lower revenues, which were partially offset by 3%, or $7.6 million, lower vessel operating costs (primarily lower repair and maintenance costs and other vessel costs which were partially offset by higher crew costs, insurance and loss reserves, and vessel operating lease costs) during the comparative periods. In addition, vessel operating profit decreased because of a 13%, or $6.0 million, increase in depreciation expense, during the same comparative periods, because of newly-constructed and acquired vessels that were added to the Sub-Saharan Africa/Europe-based fleet and because of the mobilization of vessels into this segment from other segments.

Repair and maintenance costs decreased 16%, or $6.6 million, during fiscal 2011 as compared to fiscal 2010, due to a fewer number of drydockings being performed during the current fiscal year. Other vessel costs decreased 19%, or $12.1 million, during the same comparative periods, due to a $7.6 million decrease in brokers’ commission (resulting from weaker demand for the company’s vessels in this segment) and because the prior fiscal year included a $5.0 million fine assessed by the Angolan government for failure to remit taxes in a timely manner.

Crew costs increased approximately 1%, or $1.7 million, during fiscal 2011 as compared to fiscal 2010, primarily due to an increase in the number of deepwater vessels operating in the segment. Insurance and loss

41

reserves increased approximately $3.8 million due to an increase in the number of vessels operating in this segment and due to unfavorable development of losses on a consolidated level during the current fiscal year that affected the costs of insurance for all segments. Vessel operating lease costs increased approximately $3.0 million, or 28%, during the same comparative periods, because the company entered into six additional vessel operating leases during fiscal 2010, as disclosed in Note (10) of Notes to Consolidated Financial Statements and in the “Off-Balance Sheet Arrangements” section of this report.

Other Items.    Insurance and loss reserves expense increased $6.7 million, or 51%, during fiscal 2011 as compared to fiscal 2010, because of lower premiums and favorable adjustments to loss reserves during fiscal 2010 and due to unfavorable development of losses during fiscal 2011.

Gain on asset dispositions, net during fiscal 2011 decreased approximately $15.0 million, or 53%, as compared to fiscal 2010, due to fewer vessel sales, lower gains earned on the mix of vessels sold, and higher impairment charges taken in fiscal 2011 as discussed below. Dispositions of vessels can fluctuate significantly from period to period.

The company performed a review of all its assets for asset impairment during fiscal 2011. The below table summarizes the combined fair value of the assets that incurred impairments along with the amount of impairment during the years ended March 31. The impairment charges were recorded in gain on asset dispositions, net.

Vessel Class Revenue and Statistics by Segment

Vessel utilization is determined primarily by market conditions and to a lesser extent by drydocking requirements. Vessel day rates are determined by the demand created largely through the level of offshore exploration, field development and production spending by energy companies relative to the supply of offshore service vessels. Suitability of equipment and the degree of service provided may also influence vessel day rates. Vessel utilization rates are calculated by dividing the number of days a vessel works during a reporting period by the number of days the vessel is available to work in the reporting period. As such, stacked vessels depressed utilization rates because stacked vessels are considered available to work, and as such, are included in the calculation of utilization rates. Average day rates are calculated by dividing the revenue a vessel earns during a reporting period by the number of days the vessel worked in the reporting period.

Vessel utilization and average day rates are calculated on all vessels in service (again which includes stacked vessels and vessels in drydock) but do not include vessels withdrawn from service (two vessels at March 31, 2012) or vessels owned by joint ventures (10 vessels at March 31, 2012). The following tables compare revenues, day-based utilization percentages and average day rates by vessel class and in total for each of the quarters in the years ended March 31:

The following three tables compare vessel day-based utilization percentages, average day rates and the number of active vessels (excluding stacked vessels) for the company’s new vessels (defined as vessels acquired or constructed since calendar year 2000 as part of its new build and acquisition program) and its older, or traditional, vessels for each of the quarters in the years ended March 31. Although the company is excluding the number of stacked vessels in its number of active vessels below, stacked vessels are considered to be in service and are included in the calculation of the company’s utilization statistics.

Owned or chartered vessels include vessels that were stacked by the company. The company considers a vessel to be stacked if the vessel crew is disembarked and limited maintenance is being performed on the vessel. The company reduces operating costs by stacking vessels when management does not foresee opportunities to profitably or strategically operate the vessels in the near future. Vessels are stacked when market conditions warrant and they are no longer considered stacked when they are returned to active service, sold or otherwise disposed. When economically practical marketing opportunities arise, the stacked vessels can be returned to service by performing any necessary maintenance on the vessel and either rehiring or returning fleet personnel to operate the vessel. Although not currently fulfilling charters, stacked vessels are considered to be in service and are included in the calculation of the company’s utilization statistics. The company had 67, 90 and 83 stacked vessels at March 31, 2012, 2011 and 2010, respectively. Most of the vessels stacked at March 31, 2012 are being marketed for sale and are not expected to return to the active fleet the primarily due to their age.

51

Vessels withdrawn from service are not included in the company’s utilization statistics.

Vessel Dispositions

The company seeks opportunities to sell and/or scrap its older vessels when market conditions warrant and opportunities arise. The majority of the company’s vessels are sold to buyers who do not compete with the company in the offshore energy industry. The number of vessels disposed by vessel type and segment during the fiscal years ended March 31, are as follows:

Vessel Construction and Acquisition Expenditures at March 31, 2012

At March 31, 2012, the company had two 8,200 BHP anchor handling towing supply vessels under construction at an international shipyard, for a total expected cost of $47.5 million. The first vessel was delivered in early May 2012 and the second vessel is scheduled to be delivered in June 2012. As of March 31, 2012, the company had invested $37.8 million in these two vessels.

The company is also committed to the construction of one 261-foot, four 275-foot, six 286-foot and two 300-foot deepwater platform supply vessels and two 215-foot towing supply/supply class platform supply vessels for a total estimated cost of $488.4 million. The company’s shipyard, Quality Shipyards, L.L.C., is constructing the 261-foot deepwater class vessel. One international shipyard is constructing the two 215-foot vessels. A different international shipyard is constructing the four 275-foot deepwater vessels, and a third international shipyard is constructing the six 286-foot deepwater vessels. One U.S. shipyard is constructing the two 300-foot deepwater platform supply vessels. The two 215-foot towing supply/supply class platform supply vessels are scheduled for delivery in August and October of 2013. The 261-foot deepwater platform supply vessel has an expected delivery in October 2013. The four 275-foot deepwater class vessels are expected to be delivered beginning in January 2014, with final delivery of the fourth vessel in May 2014. Delivery on the six 286-foot deepwater class vessels began in April 2012 with final delivery of the last 286-foot vessel scheduled for December 2012. The two 300-foot deepwater class vessels are scheduled for delivery in June 2013 and December 2013. As of March 31, 2012, $195.7 million was invested in these 15 vessels.

The company is also committed to the construction of one 175-foot, fast supply boat and four water jet crewboats for a cost of approximately $22.4 million. Two separate international shipyards are constructing these vessels. The company is experiencing a substantial delay with the fast supply boat, which is under construction in Brazil and was originally scheduled to be delivered in September of 2009. On April 5, 2011, pursuant to the vessel construction contract, the company sent the subject shipyard a letter initiating arbitration in order to resolve disputes of such matters as the shipyard’s failure to achieve payment milestones, its failure to follow the construction schedule, and its failure to timely deliver the vessel. The company continues to pursue arbitration of these issues. The four water jet crewboats are expected to be delivered in February, April and June of 2013. As of March 31, 2012, the company invested $11.0 million for the construction of these vessels.

At March 31, 2012, the company had agreed to purchase three platform supply vessels. The aggregate approximate purchase price for these three vessels is $58.4 million. The company took possession of one of the platform supply vessels in April 2012. This vessel has 3,000 deadweight tons of cargo capacity and was

53

purchased for a total cost of $19.8 million. The company plans to take possession of the remaining two platform supply vessels, both of which have 3,500 deadweight tons of cargo capacity, in July 2012 and in September 2012 for a total aggregate cost of $38.6 million. As of March 31, 2012, the company had invested $12.9 million in these three vessels.

(A)    The $118,856 of ‘Thereafter’ vessel construction obligations is expected to be paid out as follows: $74,997 in the remaining quarters of fiscal 2014 and $43,859 during fiscal 2015.

The company believes it has sufficient liquidity and financial capacity to support the continued investment in new vessels, assuming customer demand, acquisition and shipyard economics and other considerations justify such an investment. The company continues to evaluate its fleet renewal program, whether through new construction or acquisitions, relative to other investment opportunities and uses of cash, including the current share repurchase authorization, and in the context of its financial position and conditions in the credit and capital markets. In recent years, the company has funded vessel additions with available cash, operating cash flow, revolving credit facility borrowings, a bank term loan, various leasing arrangements, and funds provided by the sale of senior unsecured notes as disclosed in Note (4) of Notes to Consolidated Financial Statements. The company has $359.3 million in unfunded capital commitments associated with the 22 vessels currently under construction and the three vessel purchase commitments at March 31, 2012.

General and Administrative Expenses

Consolidated general and administrative expenses and its related percentage of total revenues for the years ended March 31 consist of the following components:

(In thousands)	2012				2011		%		2010		%
Personnel	$	92,293	9	%		80,100		8%		80,824		7%
Office and property		23,615	2	%		20,757		2%		19,326		2%
Sales and marketing		9,407	1	%		8,458		1%		7,553		1%
Professional services		22,326	2	%		17,972		2%		21,603		2%
Other		8,929	1	%		18,167		2%		20,626		2%
	$	156,570	15	%		145,454		14%		149,932		13%

General and administrative expenses were higher by approximately 8%, or $11.1 million, during fiscal 2012 as compared to fiscal 2011, primarily due to higher personnel costs resulting from pay raises for administrative personnel; higher accruals for incentive bonuses; an increase in costs associated with foreign assigned administrative employees (specifically foreign income taxes paid by the company on behalf of expatriate employees); higher legal fees associated with various legal matters as disclosed in Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report and “Other Liquidity Matters” below; and higher office and property expenses (primarily office rent and information technology costs). In addition, “Other” general and administrative expenses, during fiscal 2012, were lower than fiscal 2011, because the prior fiscal year included a $4.4 million settlement with the Department of Justice (DOJ) and a $6.3 million settlement with the Federal Government of Nigeria (FGN) as discussed below, and as a result of a release of approximately $1.8 million workers’ compensation reserves because of positive workers’ compensation loss experience.

General and administrative expenses were approximately 3%, or $4.5 million, lower during fiscal 2011 as compared to fiscal 2010, due to lower personnel costs (resulting from lower bonus expense); lower legal costs due to the resolution and settlement with the SEC and DOJ regarding the internal investigation matter, and lower “Other” general and administrative costs, primarily related to the release of approximately $2.6 million of workers’ compensation reserves because of positive workers’ compensation loss experience. General and administrative costs during fiscal 2011 also reflect a $4.4 million final settlement with the DOJ regarding the internal investigation and a $6.3 million settlement with the FGN to resolve the previously disclosed investigation by the FGN relating to allegations of improper payments to Nigerian government officials (which is included in “Other” general and administrative costs) as disclosed in Note (11) of Notes to Consolidated Financial Statements. Included in fiscal 2010 “Other” general and administrative expenses is a $3.6 million settlement loss related to the July 2009 supplemental retirement plan lump sum distributions as previously disclosed, and an $11.4 million SEC and DOJ settlement provision regarding the internal investigation matter.

Liquidity, Capital Resources and Other Matters

The company’s current ratio, level of working capital and amount of cash flows from operations for any year are primarily related to fleet activity, vessel day rates and the timing of collections and disbursements. Vessel activity levels and vessel day rates are, among other things, dependent upon the supply/demand relationship for offshore vessels, which tend to follow the level of oil and natural gas exploration and production. Variations from year-to-year in these items are primarily the result of market conditions.

Availability of Cash

At March 31, 2012, the company had $320.7 million in cash and cash equivalents, of which $72.6 million was held by foreign subsidiaries. The company currently intends that earnings by foreign subsidiaries will be indefinitely reinvested in foreign jurisdictions in order to fund strategic initiatives (such as investment, expansion and acquisitions), fund working capital requirements and repay debt (both third-party and intercompany) of its foreign subsidiaries in the normal course of business. Moreover, the company does not currently intend to repatriate earnings of foreign subsidiaries to the United States because cash generated from the company’s domestic businesses and credit available under its domestic financing facilities, as well as, the repayment of intercompany liabilities from foreign subsidiaries, are currently sufficient (and are expected to continue to be sufficient for the foreseeable future) to fund the cash needs of its operations in the United States. However, if, in the future, cash and cash equivalents held by foreign subsidiaries are needed to fund the company’s operations in the United States, the repatriation of such amounts to the United States could result in a significant

55

incremental tax liability in the period in which the decision to repatriate occurs. Payment of any incremental tax liability would reduce the cash available to the company to fund its operations by the amount of taxes paid.

Our objective in financing our business is to maintain adequate financial resources and access to sufficient levels of liquidity. Cash and cash equivalents, future net cash provided by operating activities and the company’s revolving credit facilities provide the company, in our opinion, with sufficient liquidity to meet our liquidity requirements, including required payments on vessel construction currently in progress and payments required to be made in connection with current vessel purchase commitments.

Indebtedness

Revolving Credit and Term Loan Agreement.    Borrowings under the company’s $575 million amended and restated revolving credit facility (“credit facility”), which includes a $125 million term loan (“term loan”) and a $450 million revolving line of credit (“revolver”) bear interest at the company’s option at the greater of (i) prime or the federal funds rate plus 0.50 to 1.25%, or (ii) Eurodollar rates plus margins ranging from 1.50 to 2.25%, based on the company’s consolidated funded debt to total capitalization ratio. Commitment fees on the unused portion of the facilities range from 0.15 to 0.35% based on the company’s funded debt to total capitalization ratio. The facilities provide for a maximum ratio of consolidated debt to consolidated total capitalization of 55% and a minimum consolidated interest coverage ratio (essentially consolidated earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four prior fiscal quarters to consolidated interest charges for such period) of 3.0. All other terms, including the financial and negative covenants, are customary for facilities of its type and consistent with the prior agreement in all material respects. The company’s credit facility matures in January 2016.

In July 2011, the credit facility was amended to allow 365 days (originally 180 days) from the closing date (“delayed draw period”) to make multiple draws under the term loan. In January 2012, the company elected to borrow the entire $125 million available under the term loan facility and used the proceeds to fund working capital and for general corporate purposes. Principal repayments on the term loan borrowings are payable in quarterly installments beginning in the quarter ending September 30, 2013 in amounts equal to 1.25% of the total outstanding borrowings as of July 26, 2013.

The company has $125 million in term loan borrowings outstanding at March 31, 2012, and the entire $450 million of the revolver was available, with no outstanding borrowings at March 31, 2012. There were no outstanding borrowings at March 31, 2011 under any of the credit facilities.

Senior Debt Notes

Fair value of debt outstanding		166,916

The multiple series of notes were originally issued with maturities ranging from approximately eight to 10 years. The notes may be retired before their respective scheduled maturity dates subject only to a customary make-whole provision. The terms of the notes require that the company maintain a minimum ratio of debt to consolidated total capitalization that does not exceed 55%.

56

September 2010 Senior Notes

On October 15, 2010, the company completed the sale of $310 million of senior unsecured notes, and the sale of an additional $115 million of the notes was completed on December 30, 2010. A summary of the aggregate amount of these notes outstanding at March 31, is as follows:

(In thousands, except weighted average data)	2012			2011
Aggregate debt outstanding	$	425,000			425,000
Weighted average remaining life in years		7.6			8.6
Weighted average coupon rate on notes outstanding		4.25	%		4.25	%
Fair value of debt outstanding		430,339			404,352

The multiple series of these notes were originally issued with maturities ranging from five to 12 years. The notes may be retired before their respective scheduled maturity dates subject only to a customary make-whole provision. The terms of the notes require that the company maintain a minimum ratio of debt to consolidated total capitalization that does not exceed 55%.

Included in accumulated other comprehensive income at March 31, 2012 and 2011, is an after-tax loss of $3.3 million ($5.1 million pre-tax), and $3.8 million ($5.8 million pre-tax), respectively, relating to the purchase of interest rate hedges, which are cash flow hedges, in July 2010 in connection with the September 2010 senior notes offering. The interest rate hedges settled in August 2010 concurrent with the pricing of the senior unsecured notes. The hedges met the effectiveness criteria and their acquisition costs are being amortized over the term of the individual notes matching the term of the hedges to interest expense.

July 2003 Senior Notes

In July 2003, the company completed the sale of $300 million of senior unsecured notes. A summary of the aggregate amount of remaining senior unsecured notes that were issued in July 2003 and outstanding at March 31, are as follows:

(In thousands, except weighted average data)	2012			2011
Aggregate debt outstanding	$	235,000			275,000
Weighted average remaining life in years		1.4			2.1
Weighted average coupon rate on notes outstanding		4.43	%		4.39	%
Fair value of debt outstanding		240,585			285,478

The multiple series of notes were originally issued with maturities ranging from seven to 12 years. These notes can be retired in whole or in part prior to maturity for a redemption price equal to the principal amount of the notes redeemed plus a customary make-whole premium. The terms of the notes provide for a maximum ratio of consolidated debt to total capitalization of 55%.

Notes totaling $40 million matured in July 2011 but were not classified as current maturities of long-term debt because the company had the ability to fund this maturity with its credit facility. Notes totaling $60 million will mature in July 2012 but are not classified as current maturities of long-term debt because the company has the ability, if necessary, to fund this maturity with its credit facility.

The company capitalizes a portion of its interest costs incurred on borrowed funds used to construct vessels. Interest and debt costs incurred, net of interest capitalized, for the years ended March 31, are as follows:

(In thousands)	2012		2011		2010
Interest and debt costs incurred, net of interest capitalized	$	22,308		10,769		1,679
Interest costs capitalized		14,743		14,878		15,632
Total interest and debt costs	$	37,051		25,647		17,311

57

Total interest and debt costs incurred during fiscal 2012 were higher than fiscal 2011 due to an increase in interest expense related to $125 million of term loan borrowing in January 2012, the issuance of $165.0 million senior notes during the quarter ended September 30, 2011, and higher commitment fees on the unused portion of the company’s credit facilities. Total interest and debt costs incurred during fiscal 2011 were higher than fiscal 2010 due to higher commitment fees on the unused portion of the company’s $575 million new facilities and higher commitment fees on the unused portion of the company’s previous facility which increased from $300 million to $450 million in July 2009.

Share Repurchases

On May 17, 2012, the company’s Board of Directors authorized the company to spend up to $200.0 million to repurchase shares of its common stock in open-market or privately-negotiated transactions. The effective date of this new authorization is July 1, 2012 through June 30, 2013. The company will use its available cash and, when considered advantageous, borrowings under its revolving credit facility or other borrowings, to fund any share repurchases.

In May 2011, the company’s Board of Directors replaced its then existing July 2009 share repurchase program with a new $200.0 million repurchase program that is in effect through June 30, 2012. The Board of Directors authorized the company to repurchase shares of its common stock in open-market or privately-negotiated transactions. The company uses its available cash and, when considered advantageous, borrowings under its revolving credit facility, or other borrowings, to fund any share repurchases. The company will evaluate share repurchase opportunities relative to other investment opportunities and in the context of current conditions in the credit and capital markets. At March 31, 2012, $165.0 million authorization remains available to repurchase shares under the May 2011 share repurchase program.

The company’s Board of Directors had previously authorized the company in July 2009 to repurchase up to $200.0 million in shares of its common stock in open-market or privately-negotiated transactions. The Board of Directors’ authorization for this repurchase program was replaced in May 2011 when the Board of Directors extended the program.

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

Net cash provided by operating activities	$	222,421			(41,785	)		264,206			(64,055	)		328,261

Cash flows from operations decreased $41.8 million, or 16%, to $222.4 million, during fiscal 2012 as compared to $264.2 million during fiscal 2011, due primarily to a decrease in net earnings, an increase in the benefit for deferred income taxes due to an increase in net loss carry forward resulting from a decrease in pretax income, a reduction in uncertain tax positions (all of which were partially offset by a goodwill impairment expense) and to changes in net operating assets and liabilities; specifically, an increase in trade and other receivable balances (because of $49.7 million lower cash collections due to the timing of payments from customers and $19.7 million higher billings to customers due to an increase in business activity), an $18.3 million increase in trade payable due to the timing of payments which provided cash, and an $11.1 million increase in accrued expenses due to the timing of accruals. It should be noted that the company is in a cyclical business and payments from customers frequently slow during periods of declining activity as some customers will seek to reduce their investment in working capital by delaying payments to service and equipment providers. Payment delays can also occur during a start-up phase on new projects and with new customers. In addition, changes in local regulations can also delay customer payments. However, there are no known material adverse trends in collections of trade receivables and we believe our allowance for doubtful accounts adequately provides for bad debts.

Cash flows from operations decreased $64.1 million, or 20%, to $264.2 million, during fiscal 2011 as compared to $328.3 million during fiscal 2010, due primarily to a decrease in net earnings, which was partially offset by changes in net operating assets and liabilities; specifically, decreases in trade and other receivable balances primarily due to $68.9 million lower cash collections due to the timing of payments from customers, $12.5 million devaluation in Venezuelan bolivar fuerte receivables (which occurred in fiscal 2010), and by $127.9 million lower billings to customers due to a decrease in business activity; $16.1 million increase in trade payables due to the timing of payments which provided cash; and increases in other current liabilities (primarily tax liabilities) because of tax settlements, net of refunds, with the U.S. federal government ($6.1 million) and the State of Louisiana ($3.2 million).

Investing Activities

Net cash used in investing activities for the years ended March 31, is as follows:

Net cash used in investing activities		$    (315,081)			254,862			(569,943	)		(271,461	)		(298,482	)

Investing activities in fiscal 2012 used $315.1 million of cash, which is attributed to $357.1 million of additions to properties and equipment partially offset by $42.0 million in proceeds from the sales of assets. Additions to properties and equipment were comprised of approximately $16.5 million in capitalized major repair costs, $336.1 million for the construction and purchase of offshore marine vessels, and $4.5 million in other properties and equipment purchases.

Investing activities in fiscal 2011 used $569.9 million of cash, which is attributed to $615.3 million of additions to properties and equipment partially offset by $37.2 million in proceeds from the sales of assets and $8.2 million

59

in proceeds from insurance settlements. Additions to properties and equipment were comprised of approximately $17.3 million in capitalized major repair costs, $588.6 million for the construction and purchase of offshore marine vessels and $9.4 million in other properties and equipment purchases.

Investing activities in fiscal 2010 used $298.5 million of cash, which is attributed to $452.0 million of additions to properties and equipment, offset by approximately $153.5 million in proceeds received from the sales of assets (of which $101.8 million resulted from the sale and leaseback of six vessels). Additions to properties and equipment were comprised of approximately $25.6 million in capitalized major repair costs, $423.4 million for the construction, purchase and/or modification of offshore marine vessels and $3.0 million of other properties and equipment purchases.

Net cash provided by (used in) financing activities		$        167,650			(160,737	)		328,387			385,889			(57,502	)

Fiscal 2012 financing activities provided $167.6 million of cash, which included $165.0 million of privately placed unsecured term debt borrowings, $125.0 of bank term loan borrowings, and $5.4 million of proceeds from the issuance of common stock resulting from stock option exercises. Proceeds were partially offset by $40.0 million used to repay debt, $51.3 million used for the quarterly payment of common stock dividends of $0.25 per common share, $35.0 million used to repurchase the company’s common stock, $1.2 million excess tax liability on stock option exercises, and $0.3 million of debt issuance costs and other items.

Fiscal 2011 financing activities provided $328.4 million of cash, which included $425.0 million of privately placed unsecured term debt borrowings, $165.0 million of credit facility borrowings, $8.7 million of proceeds from the issuance of common stock from stock option exercises and $1.2 million tax benefit on stock options exercised during the period. Proceeds were partially offset by $190.0 million used to repay debt; $51.5 million used for the quarterly payment of common stock dividends of $0.25 per common share; $20.0 million used to repurchase the company’s common stock; and $10.0 million of debt issuance costs incurred in connection with the issuance of the company’s September 2010 senior notes (inclusive of the $6.2 million cost of an interest rate swap) and the amendment and extension of the company’s revolving credit facility as discussed above.

Fiscal 2010 financing activities used $57.5 million of cash, which is primarily the result of $51.7 million used for the payment of common stock dividends of $1.00 per common share and $7.7 million of debt issuance costs related to the company’s new revolving credit agreement. Uses of cash were slightly offset by $1.8 million of proceeds from the issuance of common stock resulting from stock option exercises and $0.1 million tax benefit on stock options exercised during the year.

Other Liquidity Matters

Vessel Construction.    The company’s vessel construction program has been designed to replace over time the company’s older fleet of vessels with fewer, larger and more efficient vessels, while also opportunistically revamping the size and capabilities of the company’s fleet. The company anticipates using its existing cash balances, future operating cash flows, existing borrowing capacity and new borrowings or lease arrangements to fund current and future commitments in connection with the fleet renewal and modernization program. The company continues to evaluate its fleet renewal program, whether through new construction or acquisitions, relative to other investment opportunities and uses of cash, including the current share repurchase authorization, and in the context of current conditions in the credit and capital markets.

At March 31, 2012, the company had approximately $320.7 million of cash and cash equivalents. In addition, there was $450.0 million of credit facilities available at March 31, 2012.

Certain of the company’s vessels under construction are committed to work under customer contracts that provide for the payment of stipulated damages by the company or its subsidiaries in certain cases of late delivery or substantial reductions in rates for the inability to timely deliver a vessel that satisfies the technical specifications of the contract. Delays in the expected deliveries of any of these vessels could result in these penalties being imposed by our customers. In the opinion of management, the amount of ultimate liability, if any, with respect to these penalties will likely not have a material adverse effect on the company’s financial position, results of operations, or cash flows.

The company generally requires shipyards to provide third party credit support in the event that vessels are not completed and delivered in accordance with the terms of the shipbuilding contracts. That third party credit support typically guarantees the return of amounts paid by the company, and generally takes the form of refundment guarantees or standby letters of credit issued by major financial institutions located in the country of the shipyard. While the company seeks to minimize its shipyard credit risk by requiring these instruments, the ultimate return of amounts paid by the company in the event of shipyard default is still subject to the creditworthiness of the shipyard and the provider of the credit support, as well as the company’s ability to successfully pursue legal action to compel payment of these instruments. When third party credit support is not available or cost effective, the company endeavors to limit its credit risk through cash deposits and through other contract terms with the shipyard and other counterparties.

Currently the company is experiencing substantial delay with one fast, crew/supply boat under construction in Brazil that was originally scheduled to be delivered in September of 2009. On April 5, 2011, pursuant to the vessel construction contract, the company sent the subject shipyard a letter initiating arbitration in order to resolve disputes of such matters as the shipyard’s failure to achieve payment milestones, its failure to follow the construction schedule, and its failure to timely deliver the vessel. The company believes that the shipyard has suspended construction of the vessel. The company continues to pursue that arbitration. The company has third party credit support in the form of insurance coverage for 90% of the progress payments made on this vessel, or all but approximately $2.4 million of the carrying value of the accumulated costs through March 31, 2012.

In March 2012, the company terminated four PSV construction projects in Indonesia due to unjustified delays beyond the agreed delivery dates. The vessels were originally scheduled to deliver between May and November 2012, but had projected delivery dates ranging from August to December 2013 at the time the projects were terminated. The company had refundment guarantees in place supporting the progress payments that were made on these vessels and received the full refund including interest. During November and December of 2011, the company canceled its purchase agreements with the same shipyard for two anchor handling towing supply vessels under construction in Indonesia. The cancellations, which were due to unjustified delays beyond the agreed delivery dates, were authorized under the purchase agreements. No deposits or progress payments were involved in these two cancellations.

Two vessels under construction at a domestic shipyard have fallen substantially behind schedule. The shipyard recently notified the company that the shipyard should be entitled to a delay in the delivery date for both vessels and an increase in the contract price for the first vessel because the company was late in completing and providing the shipyard with the vessel’s detailed design drawings. The detailed design drawings were developed for the company by a third party designer. While the company believes that other factors also contributed to the delay, negotiations with the shipyard are ongoing in an attempt to reach an amicable settlement of these issues. These negotiations are at a preliminary stage.

Merchant Navy Officers Pension Fund.    A current subsidiary of the company is a participating employer in an industry-wide multi-employer retirement fund in the United Kingdom, known as the Merchant Navy Officers Pension Fund (MNOPF). The company has been informed by the Trustee of the MNOPF that the Fund has a deficit that will require contributions from the participating employers. The amount and timing of the company’s share of the fund’s deficit depends on a number of factors, including updated calculations of the total fund deficit, theories of contribution imposed as determined by and within the scope of the Trustee’s authority, the number of then participating solvent employers, and the final formula adopted to allocate the required contribution among such participating employers. The amount payable to MNOPF based on assessments was

61

$6.7 million and $9.6 million at March 31, 2012 and 2011, respectively, all of which has been accrued. The company recorded $0.3 million and $6.0 million of additional liabilities during fiscal 2012 and 2011, respectively. No additional liabilities were recorded during fiscal 2010. Payments totaling $3.1 million and $0.9 million were paid to the fund during fiscal 2012 and 2011, respectively. In the future, the fund’s Trustee may claim that the company owes additional amounts for various reasons, including negative fund investment returns or the inability of other assessed participating employers to contribute their share of respective allocations, failing which, the company and other solvent participating employers will be asked for additional contributions. In October 2010, the Trustee advised the company of its intention to accelerate previously agreed installment payments for the company and other participating employers in the scheme. The company objected to that decision and has reached an agreement in principle with the Trustee to pay the total remaining assessments (aggregating $6.7 million as of March 31, 2012) in installments through October 2014. This agreement in principle is subject to final confirmation by the company and the Trustee.

Brazilian Customs.    In April 2011, two Brazilian subsidiaries of Tidewater were notified by the Customs Office in Macae, Brazil that they were jointly and severally being assessed fines of 155.0 million Brazilian reais (approximately $90.3 million as of March 31, 2012). The assessment of these fines is for the alleged failure of these subsidiaries to obtain import licenses with respect to 17 Tidewater vessels that provided Brazilian offshore vessel services to Petrobras, the Brazilian national oil company, over a three-year period ending December 2009. After consultation with its Brazilian tax advisors, Tidewater and its Brazilian subsidiaries believe that vessels that provide services under contract to the Brazilian offshore oil and gas industry are deemed, under applicable law and regulations, to be temporarily imported into Brazil, and thus exempt from the import license requirement. The Macae Customs Office has now, without a change in the underlying applicable law or regulations, taken the position that the temporary importation exemption is only available to new, and not used, goods imported into Brazil and therefore it was improper for the company to deem its vessels as being temporarily imported. The fines have been assessed based on this new interpretation of Brazilian customs law taken by the Macae Customs Office. After consultation with its Brazilian tax advisors, the company believes that the assessment is without legal justification and that the Macae Customs Office has misinterpreted applicable Brazilian law on duties and customs. The company is vigorously contesting these fines (which it has neither paid nor accrued for) and, based on the advice of its Brazilian counsel, believes that it has a high probability of success with respect to the overturn of the entire amount of the fines, either at the administrative appeal level or, if necessary, in Brazilian courts. In December 2011, an administrative appeals board issued a decision that disallowed 149.0 million Brazilian reais (approximately $86.8 million as of March 31, 2012) of the total fines sought by the Macae Customs Office. The full decision is subject to further administrative appellate review, and the company understands that this further full review by a secondary appellate board is ongoing. The company is contesting the decision with respect to the remaining 6.0 million Brazilian reais (approximately $3.5 million as of March 31, 2012) in fines. The company believes that the ultimate resolution of this matter will not have a material effect on the consolidated financial statements.

Potential for Future Brazilian State Tax Assessment.    The company is aware that a Brazilian state in which the company has operations has notified two of the company’s competitors that they are liable for unpaid taxes (and penalties and interest thereon) for failure to pay state import taxes with respect to vessels that such competitors operate within the coastal waters of such state pursuant to charter agreements. The import tax being asserted is equal to a percentage (which could be as high as 16% for vessels entering that state’s waters prior to December 31, 2010 and 3% thereafter) of the affected vessels’ declared values. The company understands that the two companies involved are contesting the assessment through administrative proceedings before the taxing authority.

To date, the company’s two Brazilian subsidiaries, as well as vessels for all other competitors (more than a hundred competitors), have not been similarly notified by the Brazilian state that it has an import tax liability related to its vessel activities imported through that state. Although the company has been advised by its Brazilian tax counsel that substantial defenses would be available if a similar tax claim were asserted against the company, if an import tax claim were to be asserted, it could be for a substantial amount given that the company has had substantial and continuing operations within the territory of the state (although the amount could fluctuate significantly depending on the administrative determination of the taxing authority as to the rate to apply, the vessels subject to the levy and the time periods covered). In addition, under certain circumstances, the company might be required to post a bond or other adequate security in the amount of the assessment (plus any interest and penalties) if it became necessary to challenge the assessment in a Brazilian court. The

62

statute of limitations for the Brazilian state to levy an assessment of the import tax is five years from the date of a vessel’s entry into Brazil. The company has not yet determined the potential tax assessment, and according to the Brazilian tax counsel, chances of defeating a possible claim/notification from the State authorities in court are probable. To obtain legal certainty and predictability for future charter agreements and because the company was importing two vessels to start new charters in Brazil, the company filed two suits on August 22, 2011 and April 5, 2012, respectively, against the Brazilian state and judicially deposited the respective state tax for these newly imported vessels. As of March 31, 2012, no accrual has been recorded for any liability associated with any potential future assessment for previous periods based on management’s assessment, after consultation with Brazilian counsel, that a liability for such taxes was not probable.

Shareholder Derivative Suit.    In mid-February 2011, an individual claiming to be a Tidewater shareholder filed a shareholder derivative suit in the U.S. District Court for the Eastern District of Louisiana. The defendants in the suit are individual directors and certain officers of Tidewater Inc. Tidewater Inc. is also a nominal defendant in the lawsuit. The suit asserts various causes of action, including breach of fiduciary duty, against the individual defendants in connection with the facts and circumstances giving rise to the settlements with the DOJ and SEC and seeks a number of remedies against the individual defendants and the company as a result. While the company will incur costs in connection with the defense of this law suit, the suit does not seek monetary damages against the company. The individual defendants and the company have retained legal counsel. The lawsuit is still in an early stage.

Supplemental Retirement Plan.    On April 18, 2012, Dean E. Taylor, President, Chief Executive Officer and Chairman of the Board announced his retirement as President and Chief Executive Officer of Tidewater Inc. effective May 31, 2012. Mr. Taylor will continue as Tidewater’s non-executive Chairman of the Board. As a result of our CEO’s retirement, Mr. Taylor is expected to receive in December 2012 a $12.6 million lump sum distribution in settlement of his supplemental executive retirement plan obligation. A settlement loss, which is currently estimated to be $4.4 million, will be recorded at the time of distribution.

The supplemental plan was amended in December 2008 to allow participants the option to elect a lump sum benefit in lieu of other payment options currently provided by the plan. As a result of the amendment, certain participants received a lump sum distribution in July 2009 in settlement of the supplemental plan obligation. The aggregate payment to those participants electing the lump sum distribution in July 2009 was $8.7 million. A settlement loss of $3.6 million was recorded in general and administrative expenses during the second quarter of fiscal 2010.

Legal Proceedings.    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. Information related to various commitments and contingencies, including legal proceedings, is disclosed in Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report.

Venezuelan Operations

(A)    These amounts represent the liability for unrecognized tax benefits under FIN 48. The estimated income tax liabilities for uncertain tax positions will be settled as a result of expiring statutes, audit activity, competent authority proceedings related to transfer pricing, or final decisions in matters that are the subject of litigation in various taxing jurisdictions in which we operate. The timing of any particular settlement will depend on the length of the tax audit and related appeals process, if any, or an expiration of a statute. If a liability is settled due to a statute expiring or a favorable audit result, the settlement of the tax liability would not result in a cash payment.

Letters of Credit and Surety Bonds

In the ordinary course of business, the company had other commitments that the company is contractually obligated to fulfill with cash should the obligations be called. These obligations include standby letters of credit, surety bonds and performance bonds that guarantee our performance as it relates to our vessel contracts, insurance, customs and other obligations in various jurisdictions. While these obligations are not normally called, the obligation could be called by the beneficiaries at any time before the expiration date should the company breach certain contractual and/or performance or payment obligations. As of March 31, 2012, the company had $72.5 million of outstanding standby letters of credit, surety bonds and performance bonds. These obligations are geographically concentrated in Nigeria and Mexico.

Off-Balance Sheet Arrangements

Fiscal 2010 Sale/Leaseback

In June 2009, the company sold five vessels to four unrelated third-party companies, and simultaneously entered into bareboat charter agreements for the vessels with the purchasers. In July 2009, the company sold an additional vessel to an unrelated third-party company, and simultaneously entered into a bareboat charter agreement with that purchaser.

The sale/leaseback transactions resulted in proceeds to the company of approximately $101.8 million and a deferred gain of $39.6 million. The aggregate carrying value of the six vessels was $62.2 million at the dates of sale. The leases on the five vessels sold in June 2009 will expire June 30, 2014, and the lease on the vessel

64

sold in July 2009 will expire July 30, 2014. The company is accounting for the transactions as sale/leaseback transactions with operating lease treatment and expenses lease payments over the five year charter hire operating lease terms.

Under the sale/leaseback agreements, the company has the right to either re-acquire the six vessels at 75% of the original sales price or cause the owners to sell the vessels to a third-party under an arrangement where the company guarantees approximately 84% of the original lease value to the third party purchaser. The company also has the right to re-acquire the vessels prior to the end of the charter term with penalties of up to 5% assessed if purchased in years one and two of the five year lease. The company will recognize the deferred gain as income if it does not exercise its option to purchase the six vessels at the end of the operating lease term. If the company exercises its option to purchase these vessels, the deferred gain will reduce the vessels’ stated cost after exercising the purchase option.

Fiscal 2006 Sale/Leaseback

In March 2006, the company entered into agreements to sell five of its vessels that were under construction at the time to Banc of America Leasing & Capital LLC (BOAL&C), an unrelated third party, for $76.5 million and simultaneously entered into bareboat charter agreements with BOAL&C upon the vessels’ delivery to the market. Construction on these five vessels was completed at various times between March 2006 and March 2008, at which time the company sold the respective vessels and simultaneously entered into bareboat charter agreements.

The company accounted for all five transactions as sale/leaseback transactions with operating lease treatment. Accordingly, the company did not record the assets on its books and the company is expensing periodic lease payments.

The bareboat charter agreements on the first two vessels expire in calendar year 2014 unless extended. The company has the option to extend the respective bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2017. The bareboat charter agreements on the third and fourth vessels expire in 2015 and the company has the option to extend the bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2018. The bareboat charter agreement on the fifth vessel expires in 2016. The company has the option to extend the bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2019. At the end of the basic term (or extended option periods), the company has an option to purchase each of the vessels at its then fair market value or to redeliver the vessel to its owner. The company may also purchase each of the vessels at their fixed amortized values, as outlined in the bareboat charter agreements, at the end of the fifth year, and again at the end of the seventh year, from the commencement dates of the respective charter agreements.

Future Minimum Lease Payments

As of March 31, 2012, the future minimum lease payments for the vessels under the operating lease terms are as follows:

Fiscal year ending (In thousands)	Fiscal 2010 Sale/Leaseback		Fiscal 2006 Sale/Leaseback		Total
2013	$	10,702		6,924		17,626
2014		10,703		6,906		17,609
2015		2,836		5,243		8,079
2016		—		2,304		2,304
Thereafter		—		—		—
Total future lease payments	$	24,241		21,377		45,618

Application of Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures and disclosures of any contingent assets and liabilities at the date of the financial statements. We evaluate the reasonableness of these estimates and assumptions continually based on a combination of historical experience and other assumptions and information that comes to its attention that may vary its outlook for the future. Estimates and assumptions about future events and their effects are subject to uncertainty, and accordingly, these estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as the business environment in which we operate changes. As a result, actual results may differ from estimates under different assumptions.

We suggest that the company’s Nature of Operations and Summary of Significant Accounting Policies, as described in Note (1) of Notes to Consolidated Financial Statements included in Item 8 of this report, be read in conjunction with this Management’s Discussion and Analysis of Financial Condition and Results of Operations. We have defined a critical accounting estimate as one that is important to the portrayal of our financial condition or results of operations and requires us to make difficult, subjective or complex judgments or estimates about matters that are uncertain. The company believes the following critical accounting policies that affect our more significant judgments and estimates used in the preparation of the company’s consolidated financial statements are described below. There are other items within our consolidated financial statements that require estimation and judgment but they are not deemed critical as defined above.

Revenue Recognition

Our primary source of revenue is derived from time charter contracts of its vessels on a rate per day of service basis; therefore, vessel revenues are recognized on a daily basis throughout the contract period. These time charter contracts are generally either on a term basis (average three months to two years) or on a “spot” basis. The base rate of hire for a term contract is generally a fixed rate; provided, however, that term contracts at times include escalation clauses to recover increases in specific costs. A spot contract is a short-term agreement to provide offshore marine services to a customer for a specific short-term job. Spot contract terms generally range from one day to three months. Vessel revenues are recognized on a daily basis throughout the contract period. There are no material differences in the costs structure of the company’s contracts based on whether the contracts are spot or term, for the operating costs are generally the same without regard to the length of a contract.

Receivables and Allowance for Doubtful Accounts

In the normal course of business, we extend credit to our customers on a short-term basis. Our principal customers are major oil and natural gas exploration, field development and production companies. We routinely review and evaluate our accounts receivable balances for collectability. The determination of the collectability of amounts due from our customers requires us to use estimates and make judgments regarding future events and trends, including monitoring our customers’ payment history and current credit worthiness to determine that collectability is reasonably assured, as well as consideration of the overall business climate in which our customers operate. Provisions for doubtful accounts are recorded when it becomes evident that our customer will not make the required payments, which results in a reduction in our receivable balance. We believe that our allowance for doubtful accounts is adequate to cover potential bad debt losses under current conditions; however, uncertainties regarding changes in the financial condition of our customers, either adverse or positive, could impact the amount and timing of any additional provisions for doubtful accounts that may be required. During fiscal 2010, we recorded a $44.8 million provision to fully reserve accounts receivable payable by two of

66

the company’s customers located in Venezuela. Please refer to Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report for a detailed discussion regarding the company’s Venezuelan operations.

Goodwill

Goodwill represents the cost in excess of fair value of the net assets of companies acquired. The company tests goodwill for impairment annually at the reporting unit level using carrying amounts as of December 31 or more frequently if events and circumstances indicate that goodwill might be impaired. The company uses the two-step method for evaluating goodwill for impairment as prescribed by Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 350, Intangibles-Goodwill and Other. Step one involves comparing the estimated fair value of the reporting unit to its carrying amount. The estimated fair value of the reporting unit is determined by discounting the projected future operating cash flows for the remaining average useful life of the assets within the reporting units by the company’s estimated weighted average cost of capital. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit’s carrying amount is greater than the fair value, the second step must be completed to measure the amount of impairment, if any. Step two involves calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible assets, excluding goodwill, of the reporting unit from the fair value of the reporting unit as determined in step one. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. Impairment is deemed to exist if the implied fair value of the reporting unit goodwill is less than the respective carrying value of the reporting unit goodwill, and in such case, an impairment loss would be recognized equal to the difference. There are many assumptions and estimates underlying the determination of the fair value of each reporting unit, such as, future expected utilization and average day rates for the vessels, vessel additions and attrition, operating expenses and tax rates. Although the company believes its assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce a materially different result.

At March 31, 2012, the company’s goodwill balance represented 7% of total assets and 12% of stockholders’ equity. Interim testing is performed if events occur or circumstances indicate that the carrying amount of goodwill may be impaired. Examples of events or circumstances that might give rise to interim goodwill impairment testing include prolonged adverse industry or economic changes; significant business interruption due to political unrest or terrorism; unanticipated competition that has the potential to dramatically reduce the company’s earning potential; legal issues; or the loss of key personnel.

Impairment of Long-Lived Assets

The company reviews the vessels in its active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In such evaluation, the estimated future undiscounted cash flows generated by an asset group are compared with the carrying amount of the asset group to determine if a write-down may be required. With respect to vessels that have not been stacked, we group together for impairment testing purposes vessels with similar operating and marketing characteristics. We also subdivide our groupings of assets with similar operating and marketing characteristics between our older vessels and newer vessels.

The company estimates cash flows based upon historical data adjusted for the company’s best estimate of expected future market performance, which, in turn, is based on industry trends. If an asset group fails the undiscounted cash flow test, the company uses the discounted cash flow method to determine the estimated fair value of each asset group and compares such estimated fair value, considered Level 3, as defined by ASC 360, Impairment or Disposal of Long-lived Assets, to the carrying value of each asset group in order to determine if impairment exists. If impairment exists, the carrying value of the asset group is reduced to its estimated fair value.

The primary estimates and assumptions used in reviewing active vessel groups for impairment include utilization rates, average dayrates, and average daily operating expenses. These estimates are made based on recent actual trends in utilization, dayrates and operating costs and reflect management’s best estimate of expected market conditions during the period of future cash flows. These assumptions and estimates have changed considerably as market conditions have changed and they are reasonably likely to continue to change as market conditions change in the future. Although the company believes its assumptions and estimates are

67

reasonable, deviations from the assumptions and estimates could produce materially different results. Management estimates may vary considerably from actual outcomes due to future adverse market conditions or poor operating results that could result in the inability to recover the current carrying value of an asset group, thereby possibly requiring an impairment charge in the future. As the company’s fleet continues to age, management closely monitors the estimates and assumptions used in the impairment analysis in order to properly identify evolving trends and changes in market conditions that could impact the results of the impairment evaluation.

In addition to the periodic review of its active long-lived assets for impairment when circumstances warrant, the company also performs a review of its stacked vessels and vessels withdrawn from service every six months or whenever changes in circumstances indicate that the carrying amount of a vessel may not be recoverable. Management estimates each stacked vessel’s fair value by considering items such as the vessel’s age, length of time stacked, likelihood of a return to active service, actual recent sales of similar vessels, among others. In certain situations we obtain an estimate of the fair value of the stacked vessel from third-party appraisers or brokers. The company records an impairment charge when the carrying value of a vessel withdrawn from service or a stacked vessel exceeds its estimated fair value. The estimates of fair value of stacked vessels are also subject to significant variability, are sensitive to changes in market conditions, and are reasonably likely to change in the future. The company has consistently recorded modest gains on the sale of stacked vessels.

Income Taxes

The liability method is used for determining the company’s income tax provisions, under which current and deferred tax liabilities and assets are recorded in accordance with enacted tax laws and rates. Under this method, the amounts of deferred tax liabilities and assets at the end of each period are determined using the tax rate expected to be in effect when taxes are actually paid or recovered. In addition, the company determines its effective tax rate by estimating its permanent differences resulting from differing treatment of items for tax and accounting purposes.

As a global company, we are subject to the jurisdiction of taxing authorities in the United States and by the respective tax agencies in the countries in which we operate internationally, as well as to tax agreements and treaties among these governments. Our operations in these different jurisdictions are taxed on various bases: actual income before taxes, deemed profits (which are generally determined using a percentage of revenue rather than profits) and withholding taxes based on revenue. Determination of taxable income in any tax jurisdiction requires the interpretation of the related tax laws and regulations and the use of estimates and assumptions regarding significant future events such as the amount, timing and character of deductions, permissible revenue recognition methods under the tax law and the sources and character of income and tax credits. Changes in tax laws, regulations, agreements and treaties, foreign currency exchange restrictions or our level of operations or profitability in each taxing jurisdiction could have an impact on the amount of income taxes that we provide during any given year. The company is periodically audited by various taxing authorities in the United States and by the respective tax agencies in the countries in which it operates internationally. The tax audits generally include questions regarding the calculation of taxable income. Audit adjustments affecting permanent differences could have an impact on the company’s effective tax rate.

The carrying value of the company’s net deferred tax assets is based on the company’s present belief that it is more likely than not that it will be able to generate sufficient future taxable income in certain tax jurisdictions to utilize such deferred tax assets, based on estimates and assumptions. If these estimates and related assumptions change in the future, the company may be required to record or adjust valuation allowances against its deferred tax assets resulting in additional income tax expense in the company’s consolidated statement of operations. Management evaluates the realizability of the deferred tax assets and assesses the need for changes to valuation allowances on a quarterly basis. While the company has considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the present need for a valuation allowance, in the event the company were to determine that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, an adjustment to the valuation allowance would increase income in the period such determination was made. Should the company determine that it would not be able to realize all or part of its net deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was made.

68

Drydocking Costs

The company expenses maintenance and repair costs as incurred during the asset’s original estimated useful life (its original depreciable life). Major repair costs incurred after the original depreciable life that also have the effect of extending the useful life of the asset are capitalized and amortized over 30 months. Vessel modifications that are performed for a specific customer contract are capitalized and amortized over the firm contract term. Major vessel modifications are capitalized and amortized over the remaining life of the equipment. The majority of the company’s vessels require a drydocking inspection twice in every five year period, and the company schedules these drydockings when it is anticipated that the work can be performed. While the actual length of time between drydockings can vary, we use a 30 month amortization period for the costs of these drydockings as an average time between the required certifications. The company’s net earnings can fluctuate quarter to quarter due to the timing of scheduled drydockings.

Accrued Property and Liability Losses

The company self-insures a portion of potential hull damage and personal injury claims that may arise in the normal course of business. We are exposed to insurance risks related to the company’s reinsurance contracts with various insurance entities. The reinsurance recoverable amount can vary depending on the size of a loss. The exact amount of the reinsurance recoverable is not known until all losses are settled. The company estimates the reinsurance recoverable amount we expect to receive and utilizes third party actuaries to estimate losses for claims that have occurred but have not been reported or not fully developed. Reinsurance recoverable balances are monitored regularly for possible reinsurance exposure and we record adequate provisions for doubtful reinsurance receivables. It is the company’s opinion that its accounts and reinsurance receivables have no impairment other than that for which provisions have been made.

Pension and Other Postretirement Benefits

The company sponsors a defined benefit pension plan and a supplemental executive retirement plan covering eligible employees of Tidewater Inc. and participating subsidiaries. The accounting for these plans is subject to guidance regarding employers’ accounting for pensions and employers’ accounting for postretirement benefits other than pensions. Net periodic pension costs and accumulated benefit obligations are determined using a number of assumptions, of which the discount rates used to measure future obligations, expenses and expected long-term return on plan assets are most critical. Less critical assumptions, such as, the rate of compensation increases, retirement ages, mortality rates, health care cost trends, and other assumptions, also have a significant impact on the amounts reported. The company’s pension costs consists of service costs, interest costs, expected returns on plan assets, amortization of prior service costs or benefits and, in part, on a market-related valuation of assets. The company considers a number of factors in developing its pension assumptions, which are evaluated at least annually, including an evaluation of relevant discount rates, expected long-term returns on plan assets, plan asset allocations, expected changes in wages and retirement benefits, analyses of current market conditions and input from actuaries and other consultants.

The company also sponsors a post retirement plan that provides limited health care and life insurance benefits to qualified retired employees. Costs of the program are based on actuarially determined amounts and are accrued over the period from the date of hire to the full eligibility date of employees who are expected to qualify for these benefits. This plan is not funded.

New Accounting Pronouncements

For information regarding the effect of new accounting pronouncements, refer to Note (1) of Notes to Consolidated Financial Statements included in Item 8 of this report.

Effects of Inflation

Day-to-day operating costs are generally affected by inflation. Because the energy services industry requires specialized goods and services, general economic inflationary trends may not affect the company’s operating costs. The major impact on operating costs is the level of offshore exploration, field development and production spending by energy exploration and production companies. As spending increases, prices of goods and services used by the energy industry and the energy services industry will increase. Future increases in vessel day rates may shield the company from the inflationary effects on operating costs.

69

The company’s newer technologically sophisticated anchor handling towing supply vessels and platform supply vessels generally require a greater number of specially trained fleet personnel than the company’s older, smaller vessels. Competition for skilled crews will likely intensify, particularly in international markets, as new build vessels currently under construction enter the global fleet. Concerns regarding shortages in skilled labor become an increasing concern globally, During calendar year 2011, global wages in the energy industry have risen approximately 6% per analyst reports. Increases in local wages is another developing trend regarding wage inflation, especially in South America where local wages have trended higher and are now on par or have exceeded wages earned by the expatriate employee work force. If competition for personnel intensifies, the market for experienced crews could exert upward pressure on wages, which would likely increase the company’s crew costs.

Strong fundamentals in the global energy industry experienced in the past few years have also increased the activity levels at shipyards worldwide and, until the calendar year 2008-2009 global recession, the price of steel had increased dramatically due to increased worldwide demand for the metal. The price of steel continues to be high by historical standards. Although prices eased with the reduced global demand for steel in recent years, availability of iron ore, the main component of steel, is tighter today than in 2005 when prices for iron ore increased dramatically. Steel consumption increased during calendar year 2010 and into calendar 2011 but is expected to wane if the economic recovery loses momentum. If the price of steel declines, the cost of new vessels will result in lower capital expenditures and depreciation expenses, which taken by themselves would increase our future operating profits.

Environmental Compliance

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, injunction 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.

All vessels over 79 feet in registered length, regardless of flag, that are operating as a means of transportation within the inland and offshore waters of the U.S. (but not beyond the three nautical mile territorial sea limit) must comply with the Environmental Protection Agency’s National Pollutant Discharge Elimination System (NPDES) Vessel General Permit (VGP) for discharges incidental to the normal operation of vessels. For our vessels, that includes ballast water, bilge water, graywater, cooling water, chain locker effluent, deck wash down and runoff, cathodic protection, and other such type runoff. The company believes that it is in full compliance with the VGP.

The company is also involved in various legal proceedings that relate to asbestos and other environmental matters. In the opinion of management, based on current information, 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 occur. In addition, the company has established operating policies that are intended to increase awareness of actions that may harm the environment.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk refers to the potential losses arising from changes in interest rates, foreign currency fluctuations and exchange rates, equity prices and commodity prices including the correlation among these factors and their volatility. The company is primarily exposed to interest rate risk and foreign currency fluctuations and exchange risk. The company enters into derivative instruments only to the extent considered necessary to meet its risk management objectives and does not use derivative contracts for speculative purposes.

70

Interest Rate Risk and Indebtedness

Changes in interest rates may result in changes in the fair market value of the company’s financial instruments, interest income and interest expense. The company’s financial instruments that are exposed to interest rate risk are its cash equivalents and long-term borrowings. Due to the short duration and conservative nature of the cash equivalent investment portfolio, the company does not expect any material loss with respect to its investments. The book value for cash equivalents is considered to be representative of its fair value.

Revolving Credit and Term Loan Agreement

Please refer to “Liquidity, Capital Resources and Other Matters” section of this report for a discussion on the company’s revolving credit and term loan agreement and required cash payments for our indebtedness.

Because the term loan outstanding at March 31, 2012 bears interest at fixed rates, interest expense would not be impacted by changes in market interest rates. The following table discloses how the estimated fair value of our term loans as of March 31, 2012, would change with a 100 basis-point increase or decrease in market interest rates.

(In thousands)	Outstanding Value		Estimated Fair Value	100 Basis Point Increase	100 Basis Point Decrease
Term Loan	$	125,000	129,806	127,545	132,119

Senior Notes

Please refer to the “Liquidity, Capital Resources and Other Matters” section of this report for a discussion on the company’s outstanding senior notes debt.

Because the senior notes outstanding at March 31, 2012 bear interest at fixed rates, interest expense would not be impacted by changes in market interest rates. The following table discloses how the estimated fair value of our respective senior notes, as of March 31, 2012, would change with a 100 basis-point increase or decrease in market interest rates.

(In thousands)	Outstanding Value		Estimated Fair Value	100 Basis Point Increase	100 Basis Point Decrease
August 2011	$	165,000	166,916	155,695	179,124
September 2010		425,000	430,339	403,931	458,913
July 2003		235,000	240,585	237,429	243,817
Total	$	825,000	837,840	797,055	881,854

Foreign Exchange Risk

The company’s financial instruments that can be affected by foreign currency fluctuations and exchange risks consist primarily of cash and cash equivalents, trade receivables and trade payables denominated in currencies other than the U.S. dollar. The company periodically enters into spot and forward derivative financial instruments as a hedge against foreign currency denominated assets and liabilities, currency commitments, or to lock in desired interest rates. Spot derivative financial instruments are short-term in nature and settle within two business days. The fair value of spot derivatives approximates the carrying value due to the short-term nature of this instrument, and as a result, no gains or losses are recognized. Forward derivative financial instruments are generally longer-term in nature but generally do not exceed one year. The accounting for gains or losses on forward contracts is dependent on the nature of the risk being hedged and the effectiveness of the hedge.

Derivatives

The company had one foreign exchange spot contract outstanding at March 31, 2012, with a notional value of $1.0 million. The one spot contract settled by April 2, 2012. The company had eight purchase and one sell foreign exchange spot contracts outstanding at March 31, 2011, which totaled an aggregate notional value of $3.6 million. All nine spot contracts settled by April 4, 2011.

71

At March 31, 2012, the company had four British pound forward contracts outstanding totaling $7.0 million, which is generally intended to hedge the company’s foreign exchange exposure relating to its MNOPF liability as disclosed in Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report and elsewhere in this document. The forward contracts expire at various times through September 2013. The combined change in fair value of the forward contracts was approximately $0.1 million, all of which was recorded as a foreign exchange gain during the fiscal year ended March 31, 2012, because the forward contracts did not qualify as hedge instruments. All changes in fair value of the forward contracts were recorded in earnings.

At March 31, 2011, the company had three British pound forward contracts outstanding totaling $8.2 million, related to the company’s foreign exchange exposure on its MNOPF liability. The forward contracts have expiration dates between September 2011 and June 2012. The combined change in fair value of these three forward contracts at March 31, 2011 was approximately $0.3 million, all of which was recorded as a foreign exchange gain during the fiscal year ended March 31, 2011, because the forward contracts did not qualify as hedge instruments. All changes in fair value of the forward contracts were recorded in earnings.

Other

Due to the company’s international operations, the company is exposed to foreign currency exchange rate fluctuations and 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 are incurred in local currencies with the result that the company is at risk of changes in the exchange rates between the U.S. dollar and foreign currencies. 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. To minimize the financial impact of these items the company attempts to contract a significant majority of its services in U.S. dollars. In addition, the company attempts to minimize its financial impact of these risks by matching the currency of the company’s operating costs with the currency of the revenue streams when considered appropriate. The company continually monitors the currency exchange risks associated with all contracts not denominated in U.S. dollars. Discussions related to the company’s Venezuelan operations are disclosed in the “Liquidity, Capital Resources and Other Matters” section of this report and in Note (11) of Notes to Consolidated Financial Statements included in Item 8 of this report.

Devaluation of Venezuelan Bolivar Fuerte in January 2010

The company accounted for its operations in Venezuela using the U.S. dollar as its functional currency. In January 2010, the Venezuelan government announced a devaluation of the Venezuelan bolivar fuerte which modified the official fixed rate from 2.15 Venezuelan bolivar fuerte per U.S. dollar to 4.3 bolivar fuertes per U.S. dollar. In connection with the revaluation of its Venezuelan bolivar fuerte denominated net liability position, the company recorded an $11.0 million foreign exchange gain in its fiscal 2010 fourth quarter.

ITEM 9A.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed with the objective of ensuring that all information required to be disclosed in our reports filed under the Securities Exchange Act of 1934 (“Exchange Act’), such as this

72

report, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive and chief financial officers, as appropriate, to allow timely decisions regarding required disclosure. However, any control system, no matter how well conceived and followed, can provide only reasonable, and not absolute, assurance that the objectives of the control system are met.

As of the end of the period covered by this annual report, we have evaluated, under the supervision and with the participation of the company’s management, including the company’s Chairman of the Board, President and Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of the company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act, as amended).

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The company’s management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) under the Securities Exchange Act of 1934). The company’s internal control system was designed to provide reasonable assurance to the company’s management and Board of Directors regarding the reliability of financial reporting and the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The company’s management assessed the effectiveness of the company’s internal control over financial reporting as of March 31, 2012. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework. Based on our assessment we believe that, as of March 31, 2012, the company’s internal control over financial reporting is effective based on those criteria.

Deloitte & Touche LLP, the company’s registered public accounting firm that audited the company’s financial statements included in this Annual Report on Form 10-K, has issued an audit report on the effectiveness of the company’s internal control over financial reporting as of March 31, 2012, which appears on page F-3.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Tidewater Inc.

New Orleans, Louisiana

We have audited the internal control over financial reporting of Tidewater Inc. and subsidiaries (the “Company”) as of March 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2012, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended March 31, 2012 of the Company and our report dated May 21, 2012 expressed an unqualified opinion on those financial statements and financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Tidewater Inc.

New Orleans, Louisiana

We have audited the accompanying consolidated balance sheets of Tidewater Inc. and subsidiaries (the “Company”) as of March 31, 2012 and 2011, and the related consolidated statements of earnings, stockholders’ equity and other comprehensive income, and cash flows for each of the three years in the period ended March 31, 2012. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Tidewater Inc. and subsidiaries as of March 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended March 31, 2012, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

(1) NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

The company provides offshore service vessels and marine support services to the global offshore energy industry through the operation of a diversified fleet of offshore marine service vessels. The company’s revenues, net earnings and cash flows from operations are dependent upon the activity level of the vessel fleet. Like other energy service companies, the level of the company’s business activity is driven by the level of drilling and exploration activity by our customers. Our customers’ activity, in turn, is dependent on crude oil and natural gas prices, which fluctuate depending on respective levels of supply and demand for crude oil and natural gas.

Principles of Consolidation

The consolidated financial statements include the accounts of Tidewater Inc. and its subsidiaries. Intercompany balances and transactions are eliminated in consolidation.

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The accompanying consolidated financial statements include estimates for allowance for doubtful accounts, useful lives of property and equipment, valuation of goodwill, income tax provisions, impairments, commitments and contingencies and certain accrued liabilities. We evaluate our estimates and assumptions on an ongoing basis based on a combination of historical information and various other assumptions that are considered reasonable under the particular circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. These accounting policies involve judgment and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions or if different assumptions had been used, as such, actual results may differ from these estimates.

Cash Equivalents

The company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Marine Operating Supplies

Marine operating supplies, which consist primarily of operating parts and supplies for the company’s vessels, are stated at the lower of weighted-average cost or market.

Properties and Equipment

Depreciation and Amortization

Properties and equipment are stated at cost. Depreciation is computed primarily on the straight-line basis beginning with the date construction is completed, with salvage values of 5%-10% for marine equipment, using estimated useful lives of 15 - 25 years for marine equipment (from date of construction) and 3 - 30 years for other properties and equipment. Depreciation is provided for all vessels unless a vessel meets the criteria to be classified as held for sale. Estimated remaining useful lives are reviewed when there has been a change in circumstances that indicates the original estimated useful life may no longer be appropriate. Upon retirement or disposal of a fixed asset, the costs and related accumulated depreciation are removed from the respective accounts and any gains or losses are included in our consolidated statements of earnings. Used equipment is depreciated in accordance with this above policy; however, no life less than six years is used for marine equipment regardless of the date constructed.

F-9

Depreciation and amortization expense for the years ended March 31, are as follows:

(In thousands)	2012		2011		2010
Depreciation expense	$	138,356		140,576		130,184

Maintenance and Repairs

Maintenance and repairs (including major repair costs) are expensed as incurred during the asset’s original estimated useful life (its original depreciable life). Major repair costs incurred after the original estimated depreciable life that also have the effect of extending the useful life (for example, the complete overhaul of main engines, the replacement of mechanical components, or the replacement of steel in the vessel’s hull) of the asset are capitalized and amortized over 30 months. Vessel modifications that are performed for a specific customer contract are capitalized and amortized over the firm contract term. Major modifications to equipment that are being performed not only for a specific customer contract are capitalized and amortized over the remaining life of the equipment. The majority of the company’s vessels require certification inspections twice in every five year period, and the company schedules these vessel drydockings when it is anticipated that the work can be performed. While the actual length of time between drydockings can vary, we use a 30 month amortization period for the costs of these drydockings as an average time between the required certifications

Net Properties and Equipment

The following is a summary of net properties and equipment at March 31:

	2012				2011
	Number Of Vessels		Carrying Value		Number Of Vessels		Carrying Value
			(In thousands)				(In thousands)
Vessels in active service		251	$	2,567,321		262	$	2,265,042
Stacked vessels		67		34,768		90		40,224
Vessels withdrawn from service		2		633		4		673
Marine equipment and other assets under construction				261,679				358,294
Other property and equipment				41,364				37,547
Totals		320	$	2,905,765		356	$	2,701,780

The company considers a vessel to be stacked if the vessel crew is disembarked and limited maintenance is being performed on the vessel. The company reduces operating costs by stacking vessels when management does not foresee opportunities to profitably or strategically operate the vessels in the near future. Vessels are added to this list when market conditions warrant and they are removed from this list when they are returned to active service, sold or otherwise disposed. When economically practical marketing opportunities arise, the stacked vessels can be returned to service by performing any necessary maintenance on the vessel and returning fleet personnel to operate the vessel. Although not currently fulfilling charters, stacked vessels are considered to be in service and are included in the calculation of the company’s utilization statistics. Stacked vessels at March 31, 2012 and 2011 have an average age of 30.9 and 30.6 years, respectively. A vast majority of vessels stacked at March 31, 2012 are currently being marketed for sale and are not expected to return to the active fleet, primarily due to their age.

Vessels withdrawn from service represent those vessels that are not included in the company’s utilization statistics. Vessels withdrawn from service at March 31, 2012 and 2011 have an average age of 32.0 and 33.0 years, respectively.

All vessels are classified in the company’s consolidated balance sheets in Properties and Equipment. No vessels are classified as held for sale because no vessel meets the criteria. Stacked vessels and vessels withdrawn from service are reviewed for impairment semiannually.

Impairment of Long-Lived Assets

The company reviews the vessels in its active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In such evaluation, the estimated future undiscounted cash flows generated by an asset group are compared with the carrying

F-10

amount of the asset group to determine if a write-down may be required. With respect to vessels that have not been stacked, we group together for impairment testing purposes vessels with similar operating and marketing characteristics. We also subdivide our groupings of assets with similar operating and marketing characteristics between our older vessels and newer vessels.

The company estimates cash flows based upon historical data adjusted for the company’s best estimate of expected future market performance, which, in turn, is based on industry trends. If an asset group fails the undiscounted cash flow test, the company uses the discounted cash flow method to determine the estimated fair value of each asset group and compares such estimated fair value [considered Level 3, as defined by Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 360] Impairment or Disposal of Long-lived Assets, to the carrying value of each asset group in order to determine if impairment exists. If impairment exists, the carrying value of the asset group is reduced to its estimated fair value.

The primary estimates and assumptions used in reviewing active vessel groups for impairment include utilization rates, average dayrates, and average daily operating expenses. These estimates are made based on recent actual trends in utilization, dayrates and operating costs and reflect management’s best estimate of expected market conditions during the period of future cash flows. These assumptions and estimates have changed considerably as market conditions have changed and they are reasonably likely to continue to change as market conditions change in the future. Although the company believes its assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce materially different results. Management estimates may vary considerably from actual outcomes due to future adverse market conditions or poor operating results that could result in the inability to recover the current carrying value of an asset group, thereby possibly requiring an impairment charge in the future. As the company’s fleet continues to age, management closely monitors the estimates and assumptions used in the impairment analysis in order to properly identify evolving trends and changes in market conditions that could impact the results of the impairment evaluation.

In addition to the periodic review of its active long-lived assets for impairment when circumstances warrant, the company also performs a review of its stacked vessels and vessels withdrawn from service every six months or whenever changes in circumstances indicate that the carrying amount of a vessel may not be recoverable. Management estimates each stacked vessel’s fair value by considering items such as the vessel’s age, length of time stacked, likelihood of a return to active service, actual recent sales of similar vessels, among others. In certain situations we obtain an estimate of the fair value of the stacked vessel from third-party appraisers or brokers. The company records an impairment charge when the carrying value of a vessel withdrawn from service or a stacked vessel exceeds its estimated fair value. The estimates of fair value of stacked vessels are also subject to significant variability, are sensitive to changes in market conditions, and are reasonably likely to change in the future. The company has consistently recorded modest gains on the sale of stacked vessels. Refer to Note (12) for a discussion on asset impairments.

Goodwill

Goodwill represents the cost in excess of fair value of the net assets of companies acquired. Goodwill primarily relates to the fiscal 1998 acquisition of O.I.L. Ltd., a British company. The company tests goodwill for impairment annually at the reporting unit level using carrying amounts as of December 31 or more frequently if events and circumstances indicate that goodwill might be impaired. The company uses the two-step method for evaluating goodwill for impairment as prescribed in ASC 350, Intangibles-Goodwill and Other (ASC 350). Step one involves comparing the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit’s carrying amount is greater than the fair value, the second step must be completed to measure the amount of impairment, if any. Step two involves calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible assets, excluding goodwill, of the reporting unit from the fair value of the reporting unit as determined in step one. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss is recognized equal to the difference.

As discussed in Note (15), the company changed its reportable segments during the quarter ended September 30, 2011 from International and United States to Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The company performed an interim goodwill impairment assessment prior to changing its reportable segments and determined there was no goodwill impairment.

F-11

The company also performed an interim goodwill impairment assessment on the new reporting units using September 30, 2011 carrying values and determined on the basis of the step one impairment test that the carrying value of its Middle East/North Africa unit exceeded its fair value thus triggering the second step of the analysis as prescribed by ASC 350. An estimated goodwill impairment charge of $30.9 million was recorded during the quarter ended September 30, 2011. Step two of the assessment was completed during the quarter ended December 31, 2011 and there was no further adjustment to goodwill. The company performed its annual impairment test as of December 31, 2010 on its then existing International and United States reporting units, and the test determined there was no goodwill impairment. Refer to Note (15) for a complete discussion on Goodwill.

The following table summarizes goodwill as a percentage of total assets and stockholders’ equity at March 31:

	2012			2011
Goodwill as a percentage of total assets		7	%		9	%
Goodwill as a percentage of stockholders’ equity		12	%		13	%

Accrued Property and Liability Losses

The company’s insurance subsidiary establishes case-based reserves for estimates of reported losses on direct business written, estimates received from ceding reinsurers, and reserves based on past experience of unreported losses. Such losses principally relate to the company’s vessel operations and are included as a component of vessel operating costs in the consolidated statements of earnings. The liability for such losses and the related reimbursement receivable from reinsurance companies are classified in the consolidated balance sheets into current and noncurrent amounts based upon estimates of when the liabilities will be settled and when the receivables will be collected.

The following table discloses the total amount of current and long-term liabilities related to accrued property and liability losses not subject to reinsurance recoverability, but considered currently payable as of March 31:

(In thousands)	2012		2011
Accrued property and liability losses	$	6,786		9,173

Pension and Other Postretirement Benefits

The company follows the provisions of ASC 715, Compensation – Retirement Benefits, and uses a March 31 measurement date for determining net periodic benefit costs, benefit obligations and the fair value of plan assets. Net periodic pension costs and accumulated benefit obligations are determined using a number of assumptions including the discount rates used to measure future obligations and expenses, the rate of compensation increases, retirement ages, mortality rates, expected long-term return on plan assets, health care cost trends, and other assumptions, all of which have a significant impact on the amounts reported.

The company’s pension cost consists of service costs, interest costs, expected returns on plan assets, amortization of prior service costs or benefits and actuarial gains and losses. The company considers a number of factors in developing its pension assumptions, including an evaluation of relevant discount rates, expected long-term returns on plan assets, plan asset allocations, expected changes in wages and retirement benefits, analyses of current market conditions and input from actuaries and other consultants.

Net periodic benefit costs are based on a market-related valuation of assets equal to the fair value of assets. For the long-term rate of return, assumptions are developed regarding the expected rate of return on plan assets based on historical experience and projected long-term investment returns, which consider the plan’s target asset allocation and long-term asset class return expectations. Assumptions for the discount rate use the equivalent single discount rate based on discounting expected plan benefit cash flows using the Mercer Bond Index Curve for the year ended March 31, 2012, and the Citigroup Pension Discount Curve for the years ended March 31, 2011 and 2010. For the projected compensation trend rate, short-term and long-term compensation expectations for participants, including salary increases and performance bonus payments are considered. For the health care cost trend rate for other postretirement benefits, assumptions are established for health care cost trends, applying an initial trend rate that reflects recent historical experience and broader national statistics with an ultimate trend rate that assumes that the portion of gross domestic product devoted to health care

eventually becomes constant. Refer to Note (5) for a complete discussion on compensation – retirement benefits.

Income Taxes

Income taxes are accounted for in accordance with the provisions of ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are not provided on undistributed earnings of certain non-U.S. subsidiaries and business ventures because the company considers those earnings to be permanently invested abroad. Refer to Note (3) for a complete discussion on income taxes.

Revenue Recognition

The company’s primary source of revenue is derived from time charter contracts of its vessels on a rate per day of service basis; therefore, vessel revenues are recognized on a daily basis throughout the contract period. These vessel time charter contracts are generally either on a term basis (average three months to two years) or on a “spot” basis. The base rate of hire for a term contract is generally a fixed rate, provided, however, that term contracts at times include escalation clauses to recover specific additional costs. A spot contract is a short-term agreement to provide offshore marine services to a customer for a specific short-term job. Spot contract terms generally range from one day to three months. Vessel revenues are recognized on a daily basis throughout the contract period. There are no material differences in the cost structure of the company’s contracts based on whether the contracts are spot or term for the operating costs are generally the same without regard to the length of a contract.

Operating Costs

Vessel operating costs are incurred on a daily basis and consist primarily of costs such as crew wages; repair and maintenance; insurance and loss reserves; fuel, lube oil and supplies; vessel operating leases; and other vessel expenses, which include but are not limited to costs such as brokers’ commissions, training costs, agent fees, port fees, canal transit fees, temporary importation fees, vessel certification fees, and satellite communication fees. Repair and maintenance costs include both routine costs and major drydocking repair costs, which occur during the initial economic useful life of the vessel. Vessel operating costs are recognized as incurred on a daily basis.

Foreign Currency Translation

The U.S. dollar is the functional currency for all of the company’s existing international operations, as transactions in these operations are predominately denominated in U.S. dollars. Foreign currency exchange gains and losses are included in the consolidated statements of earnings.

Earnings Per Share

The company follows ASC 260, Earnings Per Share. and reports both basic earnings per share and diluted earnings per share. The calculation of basic earnings per share is computed based on the weighted average number of shares of common stock outstanding. Dilutive earnings per share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share includes the dilutive effect of stock options and restricted stock grants (both time and performance based) awarded as part of the company’s share-based compensation and incentive plans. Per share amounts disclosed in these Notes to Consolidated Financial Statements, unless otherwise indicated, are on a diluted basis. Refer to Note (9), Earnings Per Share.

Concentrations of Credit Risk

The company’s financial instruments that are exposed to concentrations of credit risk consist primarily of trade and other receivables from a variety of domestic, international and national energy companies, including

F-13

reinsurance companies for recoverable insurance losses. The company manages its exposure to risk by performing ongoing credit evaluations of its customers’ financial condition and generally does not require collateral. The company maintains an allowance for doubtful accounts for potential losses based on expected collectability and does not believe it is generally exposed to concentrations of credit risk that are likely to have a material adverse impact on the company’s financial position, results of operations, or cash flows.

Stock-Based Compensation

The company follows ASC 718, Compensation – Stock Compensation, for the expensing of stock options and other share-based payments. This topic requires that stock-based compensation transactions be accounted for using a fair-value-based method. The company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards. Refer to Note (7) for a complete discussion on stock-based compensation.

Comprehensive Income

The company reports total comprehensive income and its components in the financial statements in accordance with ASC 220, Comprehensive Income. Total comprehensive income represents the net change in stockholders’ equity during a period from sources other than transactions with stockholders and, as such, includes net earnings. For the company, accumulated other comprehensive income is comprised of unrealized gains and losses on available-for-sale securities and derivative financial instruments, currency translation adjustment and any minimum pension liability for the company’s U.S. Defined Benefits Pension Plan and Supplemental Executive Retirement Plan. Refer to Note (8) for a complete discussion on comprehensive income.

Derivative Instruments and Hedging Activities

The company periodically utilizes derivative financial instruments to hedge against foreign currency denominated assets and liabilities and currency commitments. These transactions generally include forward currency contracts or interest rate swaps that are entered into with major financial institutions. Derivative financial instruments are intended to reduce the company’s exposure to foreign currency exchange risk and interest rate risk.

The company records derivative financial instruments in its consolidated balance sheets at fair value as either assets or liabilities. The accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative and the resulting designation, which is established at the inception of a derivative. The company formally documents, at the inception of a hedge, the hedging relationship and the entity’s risk management objective and strategy for undertaking the hedge, including identification of the hedging instrument, the hedged item or transaction, the nature of the risk being hedged, the method used to assess effectiveness and the method that will be used to measure hedge ineffectiveness of derivative instruments that receive hedge accounting treatment.

For derivative instruments designated as foreign currency or interest rate hedges (cash flow hedge), changes in fair value, to the extent the hedge is effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. Hedge effectiveness is assessed quarterly based on the total change in the derivative’s fair value. Amounts representing hedge ineffectiveness are recorded in earnings. Any change in fair value of derivative financial instruments that are speculative in nature and do not qualify for hedge accounting treatment is also recognized immediately in earnings. Proceeds received upon termination of derivative financial instruments qualifying as fair value hedges are deferred and amortized into income over the remaining life of the hedged item using the effective interest rate method.

F-14

Fair Value Measurements

The company follows the provisions of ASC 820, Fair Value Measurements and Disclosures, for financial assets and liabilities that are measured and reported at fair value on a recurring basis. ASC 820 establishes a hierarchy for inputs used in measuring fair value. Fair value is calculated based on assumptions that market participants would use in pricing assets and liabilities and not on assumptions specific to the entity. The statement requires that each asset and liability carried at fair value be classified into one of the following categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data

Level 3: Unobservable inputs that are not corroborated by market data

Recasted Segment Information

In connection with a change in reportable segments, certain prior period amounts have been recast to conform to the March 31, 2012 presentation of our segments with no effect on net earnings or retained earnings. Please refer to Note (14) – Segment and Geographical Distributions of Operations.

Reclassifications

The company made certain reclassifications to prior period amounts to conform to the current year presentation. These reclassifications did not have a material effect on the consolidated statement of financial position, results of operations or cash flows.

Subsequent Events

The company evaluates subsequent events through the time of our filing on the date we issue financial statements.

Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB that are adopted by the company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the company’s consolidated financial statements upon adoption.

In September 2011, the FASB issued guidance on ASC 350, Intangibles-Goodwill and Other, for testing goodwill for impairment. The new guidance provides a company the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the company’s assessment determines that this is the case, it is required to perform the currently prescribed two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment to be recognized for that reporting unit, if any. If the company determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required. The adoption of this guidance is effective for us beginning April 1, 2012.

In June 2011, the FASB issued guidance on ASC 220, Comprehensive Income, regarding the presentation of comprehensive income. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in stockholders’ equity. Instead, a company is required to present either a continuous statement of net income and other comprehensive income or in two separate but consecutive statements. The new guidance also requires companies to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented. In December 2011, the FASB issued guidance which indefinitely defers the guidance related to the presentation of reclassification adjustments. The new guidance will be effective for us beginning April 1, 2012 and will have financial statement presentation changes only.

F-15

In May 2011, the FASB issued Accounting Standards Update No. 2011-04 (“ASU 2011-04”), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”) . This pronouncement was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The new guidance will be effective for us beginning April 1, 2012 and will not have a significant impact on our consolidated balance sheet, results of operations or cash flow.

(2) INVESTMENT IN UNCONSOLIDATED COMPANIES

Investments in unconsolidated affiliates, generally 50% or less owned partnerships and corporations, are accounted for by the equity method. Under the equity method, the assets and liabilities of the unconsolidated joint venture companies are not consolidated in the company’s consolidated balance sheet. The company does not have a significant unconsolidated subsidiary as defined by SEC Rule 3-09.

Investments in, at equity, and advances to unconsolidated joint-venture companies, which primarily represents the activities of Sonatide Marine Ltd., a 49%-owned joint venture company located in Luanda, Angola, for the years ended March 31, are as follows:

The company is not liable for U.S. taxes on undistributed earnings of most of its non-U.S. subsidiaries and business ventures that it considers indefinitely reinvested abroad because the company adopted the provisions of the American Jobs Creation Act of 2004 (the Act) effective April 1, 2005. All previously recorded deferred tax assets and liabilities related to temporary differences, foreign tax credits, or prior undistributed earnings of these entities whose future and prior earnings were anticipated to be indefinitely reinvested abroad were reversed in March 2005.

The effective tax rate applicable to pre-tax earnings for the years ended March 31, is as follows:

	2012		2011		2010
Effective tax rate applicable to pre-tax earnings	21.28	%	28.68	%	3.08	%

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at March 31, is as follows:

The company has not recognized a U.S. deferred tax liability associated with temporary differences related to investments in foreign subsidiaries that are essentially permanent in duration. The differences relate primarily to undistributed earnings and stock basis differences. Though the company does not anticipate repatriation of funds, a current U.S. tax liability would be recognized when the company receives those foreign funds in a taxable manner such as through receipt of dividends or sale of investments. A determination of the unrecognized deferred tax liability for temporary differences related to investments in foreign subsidiaries is not practicable due to uncertainty regarding the use of foreign tax credits which would become available as a result of a transaction.

The amount of foreign income that U.S. deferred taxes has not been recognized upon, as of March 31, is as follows:

In January 2008, the U.S. District Court for the Eastern District of Louisiana issued a ruling in the company’s favor with respect to a motion for summary judgment concerning the IRS disallowance of the company’s tax deduction for foreign sales corporation commissions for fiscal years 1999 and 2000. In April 2009, the Fifth Circuit Court of Appeals affirmed the District Court’s judgment. The IRS did not appeal the Court of Appeals ruling, resulting in final resolution of the issue in the company’s favor in July 2009. The tax benefit related to the issue is approximately $36.1 million, or $0.70 per common share, for fiscal year ended March 31, 2010, which primarily includes a reversal of previously recorded liabilities for uncertain tax positions and interest income on the judgment.

In March 2010, the company settled a state tax issue for fiscal years 2001 through 2003, which resulted in a tax benefit of $2.9 million, including interest of $0.8 million.

With limited exceptions, the company is no longer subject to tax audits by United States (U.S.) federal, state, local or foreign taxing authorities for years prior to 2004. The company has ongoing examinations by various state and foreign tax authorities and does not believe that the results of these examinations will have a material adverse effect on the company’s financial position or results of operations.

(4) INDEBTEDNESS

Revolving Credit and Term Loan Agreement

Borrowings under the company’s $575 million amended and restated revolving credit facility (“credit facility”), which includes a $125 million term loan (“term loan”) and a $450 million revolving line of credit (“revolver”) bear interest at the company’s option at the greater of (i) prime or the federal funds rate plus 0.50 to 1.25%, or (ii) Eurodollar rates plus margins ranging from 1.50 to 2.25%, based on the company’s consolidated funded debt to total capitalization ratio. Commitment fees on the unused portion of the facilities range from 0.15 to 0.35% based on the company’s funded debt to total capitalization ratio. The facilities provide for a maximum ratio of consolidated debt to consolidated total capitalization of 55% and a minimum consolidated interest coverage ratio (essentially consolidated earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four prior fiscal quarters to consolidated interest charges for such period) of 3.0. All other terms, including the financial and negative covenants, are customary for facilities of its type and consistent with the prior agreement in all material respects. The company’s credit facility matures in January 2016.

In July 2011, the credit facility was amended to allow 365 days (originally 180 days) from the closing date (“delayed draw period”) to make multiple draws under the term loan. In January 2012, the company elected to borrow the entire $125 million available under the term loan facility and used the proceeds to fund working capital and for general corporate purposes. Principal repayments on the term loan borrowings are payable in quarterly installments beginning in the quarter ending September 30, 2013 in amounts equal to 1.25% of the total outstanding borrowings as of July 26, 2013.

The company has $125 million in term loan borrowings outstanding at March 31, 2012, and the entire $450 million of the revolver was available, with no outstanding borrowings at March 31, 2012. There were no outstanding borrowings at March 31, 2011 under any of the credit facilities.

Senior Debt Notes

The determination of fair value includes an estimated credit spread between our long term debt and treasuries with similar matching expirations. The credit spread is determined based on comparable publicly traded companies in the oilfield service segment with similar credit ratings (Level 2 inputs as defined in the accounting guidance).

August 2011 Senior Notes

On August 15, 2011, the company issued $165 million of senior unsecured notes to a group of institutional investors. A summary of these notes outstanding at March 31, is as follows:

Fair value of debt outstanding		166,916

The multiple series of notes were originally issued with maturities ranging from approximately eight to 10 years. The notes may be retired before their respective scheduled maturity dates subject only to a customary make-whole provision. The terms of the notes require that the company maintain a minimum ratio of debt to consolidated total capitalization that does not exceed 55%.

September 2010 Senior Notes

On October 15, 2010, the company completed the sale of $310 million of senior unsecured notes, and the sale of an additional $115 million of the notes was completed on December 30, 2010. A summary of the aggregate amount of these notes outstanding at March 31, is as follows:

(In thousands, except weighted average data)		2012		2011

F-19

The multiple series of these notes were originally issued with maturities ranging from five to 12 years. The notes may be retired before their respective scheduled maturity dates subject only to a customary make-whole provision. The terms of the notes require that the company maintain a minimum ratio of debt to consolidated total capitalization that does not exceed 55%.

Included in accumulated other comprehensive income at March 31, 2012 and 2011, is an after-tax loss of $3.3 million ($5.1 million pre-tax), and $3.8 million ($5.8 million pre-tax), respectively, relating to the purchase of interest rate hedges, which are cash flow hedges, in July 2010 in connection with the September 2010 senior notes offering. The interest rate hedges settled in August 2010 concurrent with the pricing of the senior unsecured notes. The hedges met the effectiveness criteria and their acquisition costs are being amortized over the term of the individual notes matching the term of the hedges to interest expense.

July 2003 Senior Notes

In July 2003, the company completed the sale of $300 million of senior unsecured notes. A summary of the aggregate amount of remaining senior unsecured notes that were issued in July 2003 and outstanding at March 31, are as follows:

Fair value of debt outstanding		240,585		285,478

The multiple series of notes were originally issued with maturities ranging from seven to 12 years. These notes can be retired in whole or in part prior to maturity for a redemption price equal to the principal amount of the notes redeemed plus a customary make-whole premium. The terms of the notes provide for a maximum ratio of consolidated debt to total capitalization of 55%.

Notes totaling $40 million matured in July 2011 but were not classified as current maturities of long-term debt because the company had the ability to fund this maturity with its credit facility. Notes totaling $60.0 million will mature in July 2012 but are not classified as current maturities of long-term debt because the company has the ability, if necessary, to fund this maturity with its credit facility.

(5) EMPLOYEE RETIREMENT PLANS

U.S. Defined Benefit Pension Plan

The company has a defined benefit pension plan (pension plan) that covers certain U.S. citizen employees and employees who are permanent residents of the United States. Benefits are based on years of service and employee compensation. In December 2009, the Board of Directors amended the pension plan to discontinue the accrual of benefits once the plan was frozen on December 31, 2010. On that date, previously accrued pension benefits under the pension plan were frozen for the approximately 60 active employees who participated in the plan. This change did not affect benefits earned by participants prior to January 1, 2011. The active employees who participated in the pension plan have become participants in the company’s defined contribution retirement plan effective January 1, 2011. These changes are providing the company more predictable retirement plan costs and cash flows. By changing to a defined contribution plan and freezing the benefits accrued under the predecessor defined benefit plan, the company’s future benefit obligations and requirements for cash contributions for the frozen pension plan are reduced. Losses associated with the curtailment of the pension plan were immaterial. No amounts were contributed to the plan during fiscal 2012 and 2011. The company does not expect to contribute to the plan during fiscal 2013.

Supplemental Executive Retirement Plan

The company also offers a supplemental retirement plan (supplemental plan) that provides pension benefits to certain employees in excess of those allowed under the company’s tax-qualified pension plan. Assets of this non-contributory defined benefit plan are held in a Rabbi Trust, invested in a variety of marketable securities, none of which is Tidewater stock. The Rabbi Trust assets are recorded at fair value with unrealized gains or losses included in other comprehensive income. Effective March 4, 2010, the supplemental plan was closed to new participation. The company did not contribute to the Rabbi Trust during fiscal 2012 and 2011. No decision has been made as to any funding to be completed during fiscal 2013. The supplemental plan is a non-qualified plan and, as such, the company is not required to make contributions to the supplemental plan.

Investments held in a Rabbi Trust for the benefit of participants in the supplemental plan are included in other assets. The following table summarizes the carrying value of the trust assets, including unrealized gains or losses at March 31:

(In thousands)	2012		2011
Investments held in Rabbi Trust	$	17,366		18,043
Unrealized gains in carrying value of trust assets		251		523
Unrealized gains in carrying value of trust assets are net of income tax expense of		135		281
Obligations under the supplemental plan		30,633		26,197

The unrealized gains or losses in the carrying value of the trust assets, net of income tax expense, are included in accumulated other comprehensive income (other stockholders’ equity). To the extent that trust assets are liquidated to fund benefit payments, gains or losses, if any, will be recognized at that time. The company’s obligations under the supplemental plan are included in ‘accrued expenses’ and ‘other liabilities and deferred credits’ on the consolidated balance sheet.

The supplemental plan was amended in December 2008 to allow participants the option to elect a lump sum benefit in lieu of other payment options currently provided by the plan. As a result of the amendment, certain participants received a lump sum distribution in July 2009 in settlement of the supplemental plan obligation. The aggregate payment to those participants electing the lump sum distribution in July 2009 was $8.7 million. A settlement loss of $3.6 million was recorded in general and administrative expenses during fiscal 2010.

Postretirement Benefit Plan

Qualified retired employees currently are covered by a program which provides limited health care and life insurance benefits. Costs of the program are based on actuarially determined amounts and are accrued over the period from the date of hire to the full eligibility date of employees who are expected to qualify for these benefits. This plan is funded through payments as benefits are required.

Investment Strategies

Pension Plan

The obligations of our pension plan are supported by assets held in a trust for the payment of future benefits. The company is obligated to adequately fund the trust. For the pension plan assets, the company has the following primary investment objectives: (1) closely match the cash flows from the plan’s investments from interest payments and maturities with the payment obligations from the plan’s liabilities; (2) closely match the duration of plan assets with the duration of plan liabilities and (3) enhance the plan’s investment returns without taking on undue risk by industries, maturities or geographies of the underlying investment holdings.

If the plan assets are less than the plan liabilities, the pension plan assets will be invested exclusively in fixed income debt securities. Any investments in corporate bonds shall be at least investment grade, while mortgage and asset-backed securities must be rated “A” or better. If an investment is placed on credit watch, or is downgraded to a level below the investment grade, the holding will be liquidated, even at a loss, in a reasonable time period. The plan will only hold investments in equity securities if the plan assets exceed the estimated plan liabilities.

The cash flow requirements of the pension plan will be analyzed at least annually. Portfolio repositioning will be required when material changes to the plan liabilities are identified and when opportunities arise to better match cash flows with the known liabilities. Additionally, trades will occur when opportunities arise to improve the yield-to-maturity or credit quality of the portfolio.

The company’s policy for the pension plan is to contribute no less than the minimum required contribution by law and no more than the maximum deductible amount. The plan does not invest in Tidewater stock.

Supplemental Plan

The investment policy of the supplemental plan is to assess the historical returns and risk associated with alternative investment strategies to achieve an expected rate of return on plan assets. The objectives of the plan are designed to maximize total returns within prudent parameters of risk for a retirement plan of this type. The below table summarizes the supplemental plan’s minimum and maximum rate of return objectives for plan assets:

	Minimum Expected Rate of Return on Plan Assets	Maximum Expected Rate of Return on Plan Assets
Equity securities	5%	7%
Debt securities	1%	3%
Cash and cash equivalents	0%	1%

F-22

Whereas fluctuating rates of return are characteristic of the securities markets, the investment objective of the supplemental plan is to achieve investment returns sufficient to meet the actuarial assumptions. This is defined as an investment return greater than the current actuarial discount rate assumption of 4.75%, which is subject to annual upward or downward revisions. The below table summarizes the supplemental plan’s minimum and maximum market value objectives for plan assets, which are based upon a five to ten year investment horizon:

	Minimum Market Value Objective for Plan Assets	Maximum Market Value Objective for Plan Assets
Equity securities	55%	75%
Debt securities	25%	45%
Percentage of debt securities allowed in below investment grade bonds	0%	20%
Cash and cash equivalents	0%	10%

Equity holdings shall be restricted to issues of corporations that are actively traded on the major U.S. exchanges and NASDAQ. Debt security investments may include all securities issued by the U.S. Treasury or other federal agencies and investment grade corporate bonds. When a particular asset class exceeds its minimum or maximum allocation ranges, rebalancing will be addressed upon review of the quarterly performance reports and as cash contributions and withdrawals are made.

Pension and Supplemental Plan Asset Allocations

The following table provides the target and actual asset allocations for the pension plan and the supplemental plan:

	Target			Actual as of 2012			Actual as of 2011
Pension plan:
Equity securities		—			—			—
Debt securities		100	%		97	%		98	%
Cash and other		—			3	%		2	%
Total		100	%		100	%		100	%

Debt securities		35	%		32	%		29	%
Cash and other		—			5	%		7	%
Total		100	%		100	%		100	%

Significant Concentration Risks

The pension plan and the supplemental plan assets are periodically evaluated for concentration risks. As of March 31, 2012, the company did not have any individual asset investments that comprised 10% or more of each plan’s overall assets.

The pension plan assets are primarily invested in debt securities with no more than the greater of 5% of the fixed income portfolio or $2.5 million being invested in the securities of a single issuer, except investments in U.S. Treasury and other federal agency obligations. In the event that plan assets exceed the estimated plan liabilities for the pension plan, up to two times the difference between the plan assets and plan liabilities may be invested in equity securities, and so long as equities do not exceed 15% of the market value of the assets. The investment policy sets forth that the maximum single investment of the equity portfolio is 5% of the portfolio market value. Further, investments in foreign securities are restricted to American Depository Receipts (ADR) and stocks listed on the U.S. stock exchanges and may not exceed 10% of the equity portfolio.

The current diversification policy for the supplemental plan sets forth that equity securities in any single industry sector shall not exceed 25% of the equity portfolio market value and shall not exceed 10% market value of the equity portfolio for equity holdings in any single corporation. Additionally, debt securities should be diversified between issuers within each sector with no one issuer comprising more than 10% of the aggregate fixed income portfolio, excluding issues of the U.S. Treasury or other federal agencies.

To develop the expected long-term rate of return on assets assumption, the company considered the current level of expected returns on various asset classes. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected return on plan assets assumption for the portfolio.

Based upon the assumptions used to measure the company’s qualified pension and postretirement benefit obligation at March 31, 2012, including pension and postretirement benefits attributable to estimated future employee service, the company expects that benefits to be paid over the next ten years will be as follows:

	(In thousands)
Year ending March 31,	Pension Benefits		Other Benefits
2013		$        7,862		1,453
2014		15,569		1,522
2015		5,082		1,636
2016		5,255		1,672
2017		5,416		1,794
2018 – 2022		28,368		9,948
Total 10-year estimated future benefit payments		$      67,552		18,025

Health Care Cost Trends

The assumed health care cost trend rate used in measuring the accumulated postretirement benefit obligation at March 31, 2012 was 9.1% for pre-65 medical and prescription drug coverage and 7.0% for post-65 medical coverage; gradually declining to 4.5% in the year 2029. The assumed health care cost trend rate used in measuring the net periodic postretirement benefit cost for the year ended March 31, 2012 was 9.5% for pre-65 medical and prescription drug coverage and 7.0% for post-65 medical coverage; gradually declining to 4.5% in the year 2029. The health care cost trend rate used in measuring the net periodic postretirement benefit cost for fiscal 2013 is expected to be 9.1% for pre-65 medical and prescription drug coverage and 7.0% for post-65 medical coverage.

A 1% increase in the assumed health care cost trend rates for each year would increase the accumulated postretirement benefit obligation by approximately $3.9 million at March 31, 2012 and increase the total of service and interest cost for the year ended March 31, 2012 by $0.3 million. A 1% decrease in the assumed health care cost trend rates for each year would decrease the accumulated postretirement benefit obligation by approximately $3.2 million at March 31, 2012 and decrease the total of service and interest cost for the year ended March 31, 2012 by $0.2 million.

Defined Contribution Plans

Retirement Plan

A defined contribution retirement plan covers all eligible U.S. fleet personnel, along with all new eligible employees of the company hired after December 31, 1995. Effective January 1, 2011, the active employees who participated in the now frozen defined benefit pension plan have become participants in the company’s defined contribution retirement plan. This plan is noncontributory by the employee, but the company contributes, in cash, 3% of an eligible employee’s compensation to a trust on behalf of the employees. The active employees who participated in the now frozen defined benefit pension plan may receive an additional 1% to 8% depending on age and years of service. Company contributions vest over five years.

401(k) Plan

Upon meeting various citizenship, age and service requirements, employees are eligible to participate in a defined contribution savings plan and can contribute from 2% to 75% of their base salary to an employee benefit trust. The company matches with company common stock 50% of the first 8% of eligible compensation deferred by the employee. Company contributions vest over six years.

The plan held the following number of shares of Tidewater common stock as of March 31:

	2012		2011
Number of shares of Tidewater common stock held by 401(k) plan		256,816		288,200

Defined contribution plans forfeitures		335		154		568

Other Plans

A non-qualified supplemental savings plan is provided to executive officers who have the opportunity to defer up to 50% of their eligible compensation that cannot be deferred under the existing 401(k) plan due to IRS limitations. A company match may be provided on these contributions equal to 50% of the first 8% of eligible compensation deferred by the employee to the extent the employee is not able to receive the full amount of company match to the 401(k) plan due to IRS limitations. The plan also allows participants to defer up to 100% of their bonuses. In addition, an amount equal to any refunds that must be made due to the failure of the 401(k) nondiscrimination test may be deferred into this plan.

Effective March 4, 2010, the non-qualified supplemental savings plan was modified to allow the company to contribute restoration benefits to eligible employees. Employees who do not accrue a benefit in the supplemental executive retirement plan and who are eligible for a contribution in the defined contribution retirement plan automatically become eligible for the restoration benefit when the employee’s eligible retirement compensation exceeds the section 401(a)(17) limit. The restoration benefit is noncontributory by the employee, but the company contributes, in cash, 3% of an eligible employee’s compensation above the 401(a)(17) limit to a trust on behalf of the employees. The active employees who participated in the now frozen defined benefit pension plan receive an additional 1% to 8% depending on age and years of service.

The company also provides a multinational savings plan to eligible non-U.S. citizen employees working outside their respective country of origin and who have been employed for one year of continuous service with the company. Participants of the plan may contribute 1% to 15% of their base salary. The company matches, in cash, 50% of the first 6% of eligible compensation deferred by the employee. Company contributions vest over six years.

The amounts charged to expense related to the multinational pension savings plan contributions, for the fiscal years ended March 31, are as follows:

(7) STOCK-BASED COMPENSATION AND INCENTIVE PLANS

General

The company’s employee stock option, restricted stock awards, restricted stock units (that settle in Tidewater common stock), and phantom stock plans are long-term retention plans that are intended to attract, retain and provide incentives for talented employees, including officers and non-employee directors, and to align stockholder and employee interests. The company believes its employee stock option plans are critical to its operations and productivity. The employee stock option plans allow the company to grant, on a discretionary basis, both incentive and non-qualified stock options as well as restricted stock.

Under the company’s stock option and restricted stock plans, the Compensation Committee of the Board of Directors has the authority to grant stock options, restricted shares and restricted stock units of the company’s stock to officers and other key employees. Under the terms of the plans, stock options are granted with an exercise price equal to the stock’s closing fair market value on the date of grant.

The number of common stock shares reserved for issuance under the plans and the number of shares available for future grants at March 31, are as follows:

	March 31, 2012
Shares of common stock reserved for issuance under the plans		2,611,678
Shares of common stock available for future grants		886,254

Stock Option Plans

The company has granted stock options to its directors and employees, including officers, under several different stock incentive plans. Generally, options granted vest annually over a three-year vesting period measured from the date of grant. Options not previously exercised expire at the earlier of either three months after termination of the grantee’s employment or ten years after the date of grant. Upon retirement, unvested stock options are forfeited. The retiree has two years post retirement to exercise vested options. All of the stock options are classified as equity awards.

F-30

The company uses the Black-Scholes option-pricing model to determine the fair value of options granted and to calculate the share-based compensation expense. Stock options were not granted during fiscal 2012. The fair value and assumptions used for the stock options issued for the following years ended March 31, are as follows:

	2011		2010
Weighted average fair value of stock options granted		$15.92		$14.87
Risk-free interest rate		2.66%		2.66%
Expected dividend yield		2.19%		2.19%
Expected stock price volatility		38.40%		38.40%

F-31

As of March 31, 2012, total unrecognized stock-option compensation costs amounted to $2.2 million or $1.6 million net of tax. No stock option compensation costs were capitalized as part of the cost of an asset. Compensation costs for stock options that have not yet vested will be recognized as the underlying stock options vest over the appropriate future period. The level of unrecognized stock-option compensation will be affected by any future stock option grants and by the termination of any employee who has received stock options that are unvested as of the employee’s termination date.

Restricted Stock Awards

The company has granted restricted stock awards to key employees, including officers, under several different employee stock plans, which provide for the granting of restricted stock and/or performance awards to officers and key employees. The company awards both time-based and performance-based shares of restricted stock awards. The restrictions on the time-based restricted stock awards lapse generally over a four year period and require no goals to be achieved other than the passage of time and continued employment. The restrictions on the performance-based restricted stock award lapse if the company meets specific targets. During the restricted period, the restricted shares may not be transferred or encumbered, but the recipient has the right to vote the restricted shares and receive dividends on the time-based restricted shares. Dividends are accrued on performance-based restricted shares and ultimately paid only if the performance criteria is achieved. All of the restricted stock awards are classified as equity awards in stockholders’ equity. The deferred amount is generally amortized on a straight-line basis to earnings over the respective vesting periods and is net of forfeitures.

The following table sets forth a summary of restricted stock award activity of the company for fiscal 2012, 2011 and 2010:

	Weighted-average Grant-Date Fair Value		Time Based Shares			Performance Based Shares

As of March 31, 2012, total unrecognized restricted stock compensation costs amounted to $24.4 million, or $17.0 million net of tax. No restricted stock award compensation costs were capitalized as part of the costs of an asset. The amount of unrecognized restricted stock compensation will be affected by any future restricted stock grants and by the separation of an employee from the company who has received restricted stock grants that are unvested as of their separation date. There were no modifications to the restricted stock awards during fiscal 2012.

Restricted Stock Units

The company has granted restricted stock units to key employees, including officers, under the company’s employee stock plan, which provide for the granting of restricted stock units to officers and key employees. The company awards time-based units, where each unit represents the right to receive, at the end of a vesting period, one unrestricted share of Tidewater common stock with no exercise price. The company also awards performance-based restricted stock units, where each unit represents the right to receive, at the end of a vesting period, up to two shares of Tidewater common stock with no exercise price. The company uses assumptions underlying the Black-Scholes methodology to produce a Monte Carlo simulation model to value the performance-based restricted stock units. The fair value of the time-based restricted stock units is based on the market price of our common stock on the date of grant. Vesting of the performance-based restricted stock units is based on the company’s three year Total Shareholder Return (TSR) as measured against a three year TSR of a defined peer group. The restrictions on the time-based restricted stock units lapse over a three year period from the date of the award and require no goals to be achieved other than the passage of time and continued employment. The restrictions on the performance-based restricted stock units lapse if the company meets specific targets as defined. During the restricted period, the restricted stock units may not be transferred or encumbered, but the recipient has the right to receive dividend equivalents on the restricted stock units, but have no voting rights until the units vest. Dividend equivalents are accrued on performance-based restricted shares and ultimately paid only if the performance criteria is achieved. Upon retirement, the Compensation Committee of the Board of Directors will take into consideration the accelerated vesting of the restricted stock units after certain age and service criteria are met. Restricted stock unit compensation costs are recognized on a straight-line basis over the vesting period, and are net of forfeitures.

The following table sets forth a summary of restricted stock unit activity of the company for fiscal 2012:

	Weighted-average Grant-Date Fair Value		Time Based Units		Weight-average Grant Date Fair Value		Performance Based Units

There were no modifications to the restricted stock units during fiscal 2012.

Phantom Stock Plan

The company provides a Phantom Stock Plan to provide additional incentive compensation to certain key employees who are not officers of the company. The plan awards phantom stock units to participants who have the right to receive the value of a share of common stock in cash from the company. Participants have no voting or other rights as a shareholder with respect to any common stock as a result of participation in the phantom stock plan. The phantom shares generally have a three or four-year vesting period from the grant date of the award provided the employee remains employed by the company during the vesting period. Participants receive dividend equivalents at the same rate as dividends on the company’s common stock.

Non-Employee Board of Directors Deferred Stock Unit Plan

The company provides a Deferred Stock Unit Plan to its non-employee directors. The plan provides that each non-employee director is granted annually a number of stock units having an aggregate value of $100,000 on the date of grant. Dividend equivalents are paid on the stock units at the same rate as dividends on the company’s common stock and are re-invested as additional stock units based upon the fair market value of a share of company common stock on the date of payment of the dividend. A stock unit represents the right to receive from the company the equivalent value of one share of company’s common stock in cash. Payment of the value of the stock unit shall be made upon the earlier of the date that is 15 days following the date the participant ceases to be a director for any reason or upon a change of control of the company. The participant can elect to receive five annual installments or a lump sum.

In May 2011, the company’s Board of Directors replaced its then existing July 2009 share repurchase program with a new $200.0 million repurchase program that is in effect through June 30, 2012. The Board of Directors authorized the company to repurchase shares of its common stock in open-market or privately-negotiated transactions. The company uses its available cash and, when considered advantageous, borrowings under its revolving credit facility, or other borrowings, to fund any share repurchases. The company will evaluate share repurchase opportunities relative to other investment opportunities and in the context of current conditions in the credit and capital markets. At March 31, 2012, $165.0 million authorization remains available to repurchase shares under the May 2011 share repurchase program.

The company’s Board of Directors had previously authorized the company in July 2009 to repurchase up to $200.0 million in shares of its common stock in open-market or privately-negotiated transactions.

(10) SALE/LEASBACK ARRANGEMENTS

Fiscal 2010 Sale/Leaseback

In June 2009, the company sold five vessels to four unrelated third-party companies, and simultaneously entered into bareboat charter agreements for the vessels with the purchasers. In July 2009, the company sold an additional vessel to an unrelated third-party company, and simultaneously entered into a bareboat charter agreement with that purchaser.

The sale/leaseback transactions resulted in proceeds to the company of approximately $101.8 million and a deferred gain of $39.6 million. The aggregate carrying value of the six vessels was $62.2 million at the dates of sale. The leases on the five vessels sold in June 2009 will expire June 30, 2014, and the lease on the vessel sold in July 2009 will expire July 30, 2014. The company is accounting for the transactions as sale/leaseback transactions with operating lease treatment and expenses lease payments over the five year charter hire operating lease terms.

Under the sale/leaseback agreements, the company has the right to either re-acquire the six vessels at 75% of the original sales price or cause the owners to sell the vessels to a third-party under an arrangement where the company guarantees approximately 84% of the original lease value to the third party purchaser. The company also has the right to re-acquire the vessels prior to the end of the charter term with penalties of up to 5% assessed if purchased in years one and two of the five year lease. The company will recognize the deferred gain as income if it does not exercise its option to purchase the six vessels at the end of the operating lease term. If the company exercises its option to purchase these vessels, the deferred gain will reduce the vessels’ stated cost after exercising the purchase option.

Fiscal 2006 Sale/Leaseback

In March 2006, the company entered into agreements to sell five of its vessels that were under construction at the time to Banc of America Leasing & Capital LLC (BOAL&C), an unrelated third party, for $76.5 million and simultaneously entered into bareboat charter agreements with BOAL&C upon the vessels’ delivery to the market. Construction on these five vessels was completed at various times between March 2006 and March 2008, at which time the company sold the respective vessels and simultaneously entered into bareboat charter agreements.

The company accounted for all five transactions as sale/leaseback transactions with operating lease treatment. Accordingly, the company did not record the assets on its books and the company is expensing periodic lease payments.

The bareboat charter agreements on the first two vessels expire in calendar year 2014 unless extended. The company has the option to extend the respective bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2017. The bareboat charter agreements on the third and fourth vessels expire in 2015 and the company has the option to extend the bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2018. The bareboat charter agreement on the fifth vessel expires in 2016. The company has the option to extend the bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2019. At the end of the basic term (or extended option periods), the company has an option to purchase each of the vessels at its then fair market value or to redeliver the vessel to its owner. The company may also purchase each of the vessels at their fixed amortized values, as outlined in the bareboat charter agreements, at the end of the fifth year, and again at the end of the seventh year, from the commencement dates of the respective charter agreements.

(11) COMMITMENTS AND CONTINGENCIES

Compensation Commitments

Compensation continuation agreements exist with all of the company’s officers whereby each receives compensation and benefits in the event that their employment is terminated following certain events relating to a change in control of the company. The maximum amount of cash compensation that could be paid under the agreements, based on present salary levels, is approximately $39.9 million.

Vessel Commitments

The table below summarizes the company’s various vessel commitments to acquire and construct new vessels, by vessel type, as of March 31, 2012:

(In thousands, except vessel count)	Number of Vessels		Total Cost		Invested Through 3/31/12		Remaining Balance 03/31/12
Vessels under construction:
Anchor handling towing supply		2	$	47,584		37,839		9,745
Platform supply vessels		15		488,388		195,738		292,650
Crewboats		5		22,369		10,969		11,400
Total vessels under construction		22		558,341		244,546		313,795
Vessels to be purchased:

Total vessel commitments		25	$	616,728		257,437		359,291

The total cost of the various vessel new-build commitments includes contract costs and other incidental costs. The company has vessels under construction at a number of different shipyards around the world (with one of these vessels being constructed in the United States by the company’s wholly-owned shipyard, Quality Shipyards, L.L.C.). The anchor handling towing supply vessels under construction have 8,200 brake horsepower (BHP), while the platform supply vessels (PSV) under construction range between 1,900 and 6,360 deadweight tons of cargo capacity. Scheduled delivery for the new-build vessels began in April 2012, with delivery of the final new-build vessel expected in May 2014.

Regarding the vessels to be purchased, the company took possession of one PSV in April 2012 that has 3,000 deadweight tons of cargo capacity for a total cost of $19.8 million. The company plans to take possession of the remaining two PSVs, which have 3,500 deadweight tons of cargo capacity, in July 2012 and in September 2012 for a total aggregate cost of $38.6 million. As of March 31, 2012, the company had invested $12.9 million for the acquisition of these three vessels.

F-38

The company’s vessel construction program has been designed to replace over time the company’s older fleet of vessels with fewer, larger and more efficient vessels, while also opportunistically revamping the size and capabilities of the company’s fleet. The company anticipates using future operating cash flows, existing borrowing capacity and new borrowings or lease arrangements to fund current and future commitments in connection with the fleet renewal and modernization program. The company continues to evaluate its fleet renewal program, whether through new construction or acquisitions, relative to other investment opportunities and uses of cash, including the current share repurchase authorization, and in the context of current conditions in the credit and capital markets.

The company generally requires shipyards to provide third party credit support in the event that vessels are not completed and delivered in accordance with the terms of the shipbuilding contracts. That third party credit support typically guarantees the return of amounts paid by the company, and generally takes the form of refundment guarantees or standby letters of credit issued by major financial institutions located in the country of the shipyard. While the company seeks to minimize its shipyard credit risk by requiring these instruments, the ultimate return of amounts paid by the company in the event of shipyard default is still subject to the creditworthiness of the shipyard and the provider of the credit support, as well as the company’s ability to successfully pursue legal action to compel payment of these instruments. When third party credit support is not available or cost effective, the company endeavors to limit its credit risk by requiring cash deposits and through other contract terms with the shipyard and other counterparties.

Currently the company is experiencing substantial delay with one fast, crew/supply boat under construction in Brazil that was originally scheduled to be delivered in September 2009. On April 5, 2011, pursuant to the vessel construction contract, the company sent the subject shipyard a letter initiating arbitration in order to resolve disputes of such matters as the shipyard’s failure to achieve payment milestones, its failure to follow the construction schedule, and its failure to timely deliver the vessel. The company believes that the shipyard has suspended construction of the vessel. The company continues to pursue that arbitration. The company has third party credit support in the form of insurance coverage for 90% of the progress payments made on this vessel, or all but approximately $2.4 million of the carrying value of the accumulated costs through March 31, 2012.

In March 2012, the company terminated four PSV construction projects in Indonesia due to unjustified delays beyond the agreed delivery dates. The vessels were originally scheduled to deliver between May and November 2012, but had projected delivery dates ranging from August to December 2013 at the time the projects were terminated. The company had refundment guarantees in place supporting the progress payments that were made on these vessels and received the full refund including interest. During November and December of 2011, the company canceled its purchase agreements with the same shipyard for two anchor handling towing supply vessels under construction in Indonesia. The cancellations, which were due to unjustified delays beyond the agreed delivery dates, were authorized under the purchase agreements. No deposits or progress payments were involved in these two cancellations.

Two vessels under construction at a domestic shipyard have fallen substantially behind schedule. The shipyard recently notified the company that the shipyard should be entitled to a delay in the delivery date for both vessels and an increase in the contract price for the first vessel because the company was late in completing and providing the shipyard with the vessel’s detailed design drawings. The detailed design drawings were developed for the company by a third party designer. While the company believes that other factors also contributed to the delay, negotiations with the shipyard are ongoing in an attempt to reach an amicable settlement of these issues. These negotiations are at a preliminary stage.

Completion of Internal Investigation and Settlements with United States and Nigerian Agencies

The company has previously reported that special counsel engaged by the company’s Audit Committee had completed an internal investigation into certain Foreign Corrupt Practices Act (FCPA) matters and reported its findings to the Audit Committee. The substantive areas of the internal investigation have been reported publicly by the company in prior filings.

Special counsel has reported to the Department of Justice (DOJ) and the Securities and Exchange Commission (SEC) the results of the investigation, and the company has entered into separate agreements with the two agencies to resolve the matters reported by special counsel. The company has previously reported the principal terms of these agreements.

F-39

Securities and Exchange Commission

As previously reported, the company reached an agreement with the SEC to resolve its previously disclosed investigation of possible violations of the FCPA. Under the agreement, the company consented to the filing in federal district court of a complaint (“SEC Complaint”) by the SEC against Tidewater Inc., without admitting or denying the allegations in the SEC Complaint, and to the entry by the court of a final judgment and permanent injunction. On November 8, 2010, a federal district court entered a final judgment approving the agreement.

The agreement required Tidewater Inc. to pay a total of approximately $11.4 million, consisting of $8.4 million (principally representing disgorgement of profits and prejudgment interest) payable at the time of settlement and a contingent civil penalty of $3.0 million. The contingent civil penalty was to be payable to the SEC in the event that the company had not otherwise agreed within 18 months of the date the court entered judgment to pay fines or penalties of at least that amount to another United States government authority (or authorities) in connection with the matters covered by the SEC Complaint. Given the agreement reached with the DOJ (discussed below), no contingent civil penalty was required to be paid to the SEC. The full $11.4 million financial charge associated with the settlement with the SEC, however, was recorded in the fourth quarter of fiscal 2010 and was included in general and administrative expenses. The $8.4 million settlement was paid to the SEC in the third quarter of fiscal 2011 after the federal district court approved the agreement.

Department of Justice

The company reached an agreement with the DOJ to resolve its previously disclosed investigation of possible violations of the FCPA. Under the agreement, Tidewater Marine International Inc. (“TMII”), a wholly-owned subsidiary of the company organized in the Cayman Islands, and the DOJ entered into a Deferred Prosecution Agreement (“DPA”). Pursuant to the DPA, the DOJ deferred criminal charges against TMII for a period of three years and seven days from the date of judicial approval of the Agreement, in return for: (a) TMII’s acceptance of responsibility for, and agreement not to contest or contradict the truthfulness of, the statement of facts and allegations contained in a three-count criminal information to be filed concurrently with the DPA; (b) TMII’s payment of a $7.35 million fine, (c) TMII’s and Tidewater Inc.’s compliance with certain undertakings relating to compliance with the FCPA and other applicable laws in connection with the Company’s operations, and cooperation with domestic and foreign authorities in connection with the matters that are the subject of the DPA; (d) TMII’s and Tidewater Inc.’s agreement to continue to address any deficiencies in the company’s internal controls, policies and procedures relating to compliance with the FCPA and other applicable anti-corruption laws, if and to the extent not already addressed; and (e) Tidewater Inc.’s agreement to report to the DOJ in writing annually for the term of the DPA regarding remediation of the matters that are the subject of the DPA, the implementation of any enhanced internal controls, and any evidence of improper payments the company may have discovered during the term of the DPA. Tidewater submitted its first annual report to the DOJ in November 2011.

If TMII and Tidewater Inc. comply with the DPA during its term, the DOJ will not bring the charges set out in the information. In the event TMII or Tidewater Inc. breaches the DPA, the DOJ has discretion to extend its term for up to a year, or bring certain criminal charges against TMII as outlined in the DPA.

A federal district court accepted the DPA on November 9, 2010. In the quarter ended December 31, 2010, TMII paid the $7.35 million fine. Implementation of the DOJ settlement eliminated the $3.0 million contingent civil penalty in connection with the SEC civil settlement detailed above. An additional financial charge of $4.35 million associated with the DOJ settlement was recorded during the quarter ended September 30, 2010 and was included in general and administrative expenses.

Settlement with the Nigerian Government

The company announced on March 3, 2011, that it had reached an agreement with the Federal Government of Nigeria (“FGN”) to settle and resolve the previously disclosed investigation by the FGN. As part of that agreement, one of the company’s Nigerian subsidiaries agreed to pay $6.0 million to the FGN and to pay an additional $0.3 million for the FGN’s attorneys’ fees and other expenses. The total $6.3 million ($0.12 per diluted common share) settlement payments were recorded and paid during the quarter ended March 31, 2011.

Merchant Navy Officers Pension Fund

A current subsidiary of the company is a participating employer in an industry-wide multi-employer retirement fund in the United Kingdom, known as the Merchant Navy Officers Pension Fund (MNOPF). The company has been informed by the Trustee of the MNOPF that the Fund has a deficit that will require contributions from the participating employers. The amount and timing of the company’s share of the fund’s deficit depends on a number of factors, including updated calculations of the total fund deficit, theories of contribution imposed as determined by and within the scope of the Trustee’s authority, the number of then participating solvent employers, and the final formula adopted to allocate the required contribution among such participating employers. The amount payable to MNOPF based on assessments was $6.7 million and $9.6 million at March 31, 2012 and 2011, respectively, all of which has been accrued. The company recorded $0.3 million and $6.0 million of additional liabilities during fiscal 2012 and 2011 respectively. No additional liabilities were recorded during fiscal 2010. Payments totaling $3.1 million and $0.9 million were paid to the fund during fiscal 2012 and 2011 respectively. In the future, the fund’s Trustee may claim that the company owes additional amounts for various reasons, including negative fund investment returns or the inability of other assessed participating employers to contribute their share of respective allocations, failing which, the company and other solvent participating employers will be asked for additional contributions. In October 2010, the Trustee advised the company of its intention to accelerate previously agreed installment payments for the company and other participating employers in the scheme. The company objected to that decision and has reached an agreement in principle with the Trustee to pay the total remaining assessments (aggregating $6.7 million as of March 31, 2012) in installments through October 2014. This agreement in principle is subject to final confirmation by the company and the Trustee.

Sonatide Joint Venture

The company has previously announced that its existing Sonatide joint venture agreement with Sonangol had been extended to May 31, 2012 to allow ongoing joint venture restructuring negotiations to continue.

The company has from time to time also provided updates regarding the status of its continuing negotiations with Sonangol to put its Sonatide joint venture on a more permanent footing after a number of temporary extensions of the original joint venture agreement. As previously disclosed, in March 2012, Sonangol informed Tidewater that it would not permit further vessel contracting activity by Sonatide until the joint venture negotiations had been resolved to the parties’ mutual satisfaction. As a result, the company has begun deploying vessels (at prevailing market day rates) to other markets as those vessels become available.

The company has recently exchanged proposals and is continuing discussions with Sonangol. In the most recent meeting between the two negotiating teams, only modest progress was made in the restructuring negotiations, and important and fundamental issues regarding the restructured relationship remain outstanding and unresolved. In that meeting, Sonangol and the company discussed a number of topics, up to and including the potential issues associated with a wind up of the existing joint venture in the event restructuring discussions are not ultimately successful. If negotiations relating to putting the Sonatide joint venture on a more permanent footing are ultimately unsuccessful, the company will work toward an orderly wind up of the joint venture. We believe, however, that the joint venture would be allowed to honor existing vessel charter agreements through their contract terms. Even though the global market for offshore supply vessels appears to be well balanced (and the market for deepwater supply vessels is currently strong), there would be financial impacts associated with the wind up of the existing joint venture and the possible redeployment of vessels to other markets, including mobilization costs and costs to redeploy Tidewater shore-based employees to other areas, in addition to lost revenues associated with potential downtime between vessel contracts. These financial impacts could, individually or in the aggregate, be material to our results of operations and cash flows. If there is a need to redeploy vessels which are currently deployed in Angola to other international markets, Tidewater believes that there is sufficient demand for these vessels at prevailing market day rates.

For the year ended March 31, 2012, Tidewater’s Angolan operations generated vessel revenues of approximately $254 million, or 24% of its consolidated vessel revenue, from an average of approximately 93 vessels (14 of which were stacked on average in fiscal 2012), and, for the year ended March 31, 2011, generated vessel revenues of approximately $237 million, or 23% of consolidated vessel revenue, from an average of approximately 97 vessels (13 of which were stacked on average in fiscal 2011). As of March 31, 2012, the carrying value of Tidewater’s investment in the Sonatide joint venture, which is included in “Investments in, at equity, and advances to unconsolidated companies,” is approximately $46 million.

F-41

Brazilian Customs

In April 2011, two Brazilian subsidiaries of Tidewater were notified by the Customs Office in Macae, Brazil that they were jointly and severally being assessed fines of 155.0 million Brazilian reais (approximately $90.3 million as of March 31, 2012). The assessment of these fines is for the alleged failure of these subsidiaries to obtain import licenses with respect to 17 Tidewater vessels that provided Brazilian offshore vessel services to Petrobras, the Brazilian national oil company, over a three-year period ending December 2009. After consultation with its Brazilian tax advisors, Tidewater and its Brazilian subsidiaries believe that vessels that provide services under contract to the Brazilian offshore oil and gas industry are deemed, under applicable law and regulations, to be temporarily imported into Brazil, and thus exempt from the import license requirement. The Macae Customs Office has now, without a change in the underlying applicable law or regulations, taken the position that the temporary importation exemption is only available to new, and not used, goods imported into Brazil and therefore it was improper for the company to deem its vessels as being temporarily imported. The fines have been assessed based on this new interpretation of Brazilian customs law taken by the Macae Customs Office. After consultation with its Brazilian tax advisors, the company believes that the assessment is without legal justification and that the Macae Customs Office has misinterpreted applicable Brazilian law on duties and customs. The company is vigorously contesting these fines (which it has neither paid nor accrued for) and, based on the advice of its Brazilian counsel, believes that it has a high probability of success with respect to the overturn of the entire amount of the fines, either at the administrative appeal level or, if necessary, in Brazilian courts. In December 2011, an administrative appeals board issued a decision that disallowed 149.0 million Brazilian reais (approximately $86.8 million as of March 31, 2012) of the total fines sought by the Macae Customs Office. The full decision is subject to further administrative appellate review, and the company understands that this further full review by a secondary appellate board is ongoing. The company is contesting the decision with respect to the remaining 6.0 million Brazilian reais (approximately $3.5 million as of March 31, 2012) in fines. The company believes that the ultimate resolution of this matter will not have a material effect on the consolidated financial statements.

Potential for Future Brazilian State Tax Assessment

The company is aware that a Brazilian state in which the company has operations has notified two of the company’s competitors that they are liable for unpaid taxes (and penalties and interest thereon) for failure to pay state import taxes with respect to vessels that such competitors operate within the coastal waters of such state pursuant to charter agreements. The import tax being asserted is equal to a percentage (which could be as high as 16% for vessels entering that state’s waters prior to December 31, 2010 and 3% thereafter) of the affected vessels’ declared values. The company understands that the two companies involved are contesting the assessment through administrative proceedings before the taxing authority.

To date, the company’s two Brazilian subsidiaries, as well as vessels for all other competitors (more than a hundred competitors), have not been similarly notified by the Brazilian state that it has an import tax liability related to its vessel activities imported through that state. Although the company has been advised by its Brazilian tax counsel that substantial defenses would be available if a similar tax claim were asserted against the company, if an import tax claim were to be asserted, it could be for a substantial amount given that the company has had substantial and continuing operations within the territory of the state (although the amount could fluctuate significantly depending on the administrative determination of the taxing authority as to the rate to apply, the vessels subject to the levy and the time periods covered). In addition, under certain circumstances, the company might be required to post a bond or other adequate security in the amount of the assessment (plus any interest and penalties) if it became necessary to challenge the assessment in a Brazilian court. The statute of limitations for the Brazilian state to levy an assessment of the import tax is five years from the date of a vessel’s entry into Brazil. The company has not yet determined the potential tax assessment, and according to the Brazilian tax counsel, chances of defeating a possible claim/notification from the State authorities in court are probable. To obtain legal certainty and predictability for future charter agreements and because the company was importing two vessels to start new charters in Brazil, the company filed two suits on August 22, 2011 and April 5, 2012, respectively, against the Brazilian state and judicially deposited the respective state tax for these newly imported vessels. As of March 31, 2012, no accrual has been recorded for any liability associated with any potential future assessment for previous periods based on management’s assessment, after consultation with Brazilian counsel, that a liability for such taxes was not probable.

F-42

Venezuelan Operations

The company has previously reported that in May 2009 the Venezuelan National Assembly enacted a law (the Reserve Law) whereby the Bolivarian Republic of Venezuela (Venezuela) reserved to itself assets and services related to maritime activities on Lake Maracaibo. The company also previously reported that in May 2009, Petróleos de Venezuela, S.A. (PDVSA), the Venezuelan national oil company, invoking the Reserve Law, took possession of (a) 11 of the company’s vessels that were then supporting PDVSA operations in the Lake Maracaibo region, (b) the company’s shore-based facility adjacent to Lake Maracaibo and (c) certain other related assets. The company has also previously reported that in July 2009, Petrosucre, S.A. (Petrosucre), a subsidiary of PDVSA, took control of four additional company vessels. As a consequence of these measures, the company (i) no longer has possession or control of those assets, (ii) no longer operates them or provides support for their operations, and (iii) no longer has any other vessels or operations in Venezuela.

As a result of the May 2009 seizure of the 11 vessels and other assets discussed above, the company recorded a charge of $3.75 million ($2.9 million after tax, or $0.06 per common share), during the quarter ended June 30, 2009, to write off the net book value of the assets seized. As a result of the July 2009 vessel seizures, the company recorded a charge of $0.5 million ($0.4 million after tax, or $0.01 per common share) during the quarter ended September 30, 2009, to write off the net book value of those assets.

As a result of the asset seizures referred to above, the lack of further operations in Venezuela, and the continuing uncertainty about the timing and amount of the compensation that the company may collect in the future (including compensation for the taking of the accounts receivable payable by PDVSA and Petrosucre), the company recorded a $44.8 million ($44.8 million after tax, or $0.87 per common share) provision during the quarter ended June 30, 2009, to fully reserve accounts receivable payable by PDVSA and Petrosucre.

As previously reported by the company, the company filed with the International Centre for Settlement of Investment Disputes (ICSID) a Request for Arbitration against the Republic of Venezuela seeking compensation for the expropriation of the company’s Venezuelan investments. On January 24, 2011, the arbitration tribunal, appointed under the ICSID Convention to resolve the investment dispute, held its first session on procedural issues in Washington, D.C. The arbitration tribunal established a briefing and hearing schedule related to jurisdictional issues. The briefing and hearings on jurisdiction concluded on March 1, 2012. The company expects the arbitration tribunal to issue a written ruling on jurisdictional issues in the second half of 2012. To the extent that the arbitration tribunal finds a basis for jurisdiction over this dispute, the company intends to continue diligently to prosecute its claim in the arbitration. While the company believes, after consultation with its advisors, that it is entitled to full reparation for the losses suffered as a result of the actions taken by the Republic, there can be no assurances that the company will prevail in the arbitration.

Currency Devaluation and Fluctuation Risk

Due to the company’s global operations, the company is exposed to foreign currency exchange rate fluctuations and exchange rate risks on all charter hire contracts denominated in foreign currencies. For some of our non-U.S. contracts, a portion of the revenue and local expenses are incurred in local currencies with the result that the company is at risk of changes in the exchange rates between the U.S. dollar and foreign currencies. 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. To minimize the financial impact of these items, the company attempts to contract a significant majority of its services in U.S. dollars. In addition, the company attempts to minimize its financial impact of these risks, by matching the currency of the company’s operating costs with the currency of the revenue streams when considered appropriate. The company continually monitors the currency exchange risks associated with all contracts not denominated in U.S. dollars.

Legal Proceedings

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.

(12) FAIR VALUE MEASUREMENTS AND DISCLOSURES

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Other Financial Instruments

The company’s primary financial instruments consist of cash and cash equivalents, trade receivables and trade payables with book values that are considered to be representative of their respective fair values. The company periodically utilizes derivative financial instruments to hedge against foreign currency denominated assets and liabilities, currency commitments, or to lock in desired interest rates. These transactions are generally spot or forward currency contracts or interest rate swaps that are entered into with major financial institutions. Derivative financial instruments are intended to reduce the company’s exposure to foreign currency exchange risk and interest rate risk. The company enters into derivative instruments only to the extent considered necessary to address its risk management objectives and does not use derivative contracts for speculative purposes. The derivative instruments are recorded at fair value using quoted prices and quotes obtainable from the counterparties to the derivative instruments.

Cash Equivalents. The company’s cash equivalents, which are securities with maturities less than 90 days, are held in money market funds or time deposit accounts with highly rated financial institutions. The carrying value for cash equivalents is considered to be representative of its fair value due to the short duration and conservative nature of the cash equivalent investment portfolio.

Spot Derivatives. Spot derivative financial instruments are short-term in nature and generally settle within two business days. The fair value of spot derivatives approximates the carrying value due to the short-term nature of this instrument, and as a result, no gains or losses are recognized.

The company had one foreign exchange spot contract outstanding at March 31, 2012, which totaled a notional value of $1.0 million. The one spot contract settled by April 2, 2012. The company had eight purchase and one sell foreign exchange spot contracts outstanding at March 31, 2011, which totaled an aggregate notional value of $3.6 million. All nine spot contracts settled by April 4, 2011.

Forward Derivatives. Forward derivative financial instruments are generally longer-term in nature but generally do not exceed one year. The accounting for gains or losses on forward contracts is dependent on the nature of the risk being hedged and the effectiveness of the hedge.

At March 31, 2012, the company had four British pound forward contracts outstanding, which is generally intended to hedge the company’s foreign exchange exposure relating to its MNOPF liability as disclosed in Note (11) and elsewhere in this document. The forward contracts expire at various times through March 2013. The combined change in fair value of the forward contracts was approximately $0.1 million, all of which was recorded as a foreign exchange gain during the fiscal year ended March 31, 2012, because the forward contracts did not qualify as hedge instruments. All changes in fair value of the forward contracts were recorded in earnings.

At March 31, 2011, the company had three British pound forward contracts outstanding, related to the company’s foreign exchange exposure on its MNOPF liability. The combined change in fair value of these forward contracts at March 31, 2011 was approximately $0.3 million, all of which was recorded as a foreign exchange gain during the fiscal year ended March 31, 2011, because the forward contracts did not qualify as hedge instruments.

The following table provides the fair value hierarchy for the company’s other financial instruments measured as of March 31, 2012:

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Asset Impairments

The company accounts for long-lived assets in accordance with ASC 360-10-35, Impairment or Disposal of Long-Lived Assets. The company reviews the vessels in its active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In such evaluation the estimated future undiscounted cash flows generated by an asset group are compared with the carrying amount of the asset group to determine if a write-down may be required. With respect to vessels that have not been stacked, we group together for impairment testing purposes vessels with similar operating and marketing characteristics. We also subdivide our groupings of assets with similar operating and marketing characteristics between our older vessels and newer vessels.

The company estimates cash flows based upon historical data adjusted for the company’s best estimate of expected future market performance, which, in turn, is based on industry trends. If an asset group fails the undiscounted cash flow test, the company uses the discounted cash flow method to determine the estimated fair value of each asset group and compares such estimated fair value (considered Level 3, as defined by ASC 360) to the carrying value of each asset group in order to determine if impairment exists. If impairment exists, the carrying value of the asset group is reduced to its estimated fair value.

In addition to the periodic review of its active long-lived assets for impairment when circumstances warrant, the company also performs a review of its stacked vessels and vessels withdrawn from service every six months or whenever changes in circumstances indicate that the carrying amount of a vessel may not be recoverable. Management estimates each stacked vessel’s fair value by considering items such as the vessel’s age, length of time stacked, likelihood of a return to active service, actual recent sales of similar vessels, among others. In certain situations we obtain an estimate of the fair value of the stacked vessel from third-party appraisers or brokers. The company records an impairment charge when the carrying value of a vessel withdrawn from service or a stacked vessel exceeds its estimated fair value. The estimates of fair value of stacked vessels are also subject to significant variability, are sensitive to changes in market conditions, and are reasonably likely to change in the future.

The below table summarizes the combined fair value of the assets that incurred impairments along with the amount of impairment during the years ended March 31. The impairment charges were recorded in gain on asset dispositions, net.

(In thousands)	2012		2011		2010

The company seeks opportunities to dispose its older vessels when market conditions warrant and opportunities arise. As such, dispositions of vessels can vary from year to year; therefore, gains on sales of assets may fluctuate significantly from period to period. The majority of the company’s vessels are sold to buyers who do not compete with the company in the offshore energy industry.

F-45

The number of vessels disposed along with the gain on the dispositions for the years ended March 31, are as follows:

(In thousands, except number of vessels disposed)	2012		2011		2010
Gain on vessels disposed	$	20,024		21,663		30,646

(14) SEGMENT INFORMATION, GEOGRAPHICAL DATA AND MAJOR CUSTOMERS

The company follows the disclosure requirements of ASC 280, Segment Reporting. Operating business segments are defined as a component of an enterprise for which separate financial information is available and is evaluated by the chief operating decision maker in deciding how to allocate resources and in assessing performance.

During the quarter ended September 30, 2011, our International and United States segments were reorganized to form four new operating segments. We now manage and measure our business performance in four distinct operating segments which are based on our geographical organization: Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The new segments are reflective of how the company’s chief operating decision maker (CODM) reviews operating results for the purposes of allocating resources and assessing performance. The company’s CODM is its Chief Executive Officer. Moreover, management decided to reorganize its reporting segments because the company’s Sub-Saharan Africa/Europe and Latin American business regions gained greater significance as a percentage of consolidated revenues and operating profit, while our former United States segment decreased in its significance to consolidated revenues and operating profit. Prior period disclosures have been adjusted to reflect the change in reportable segments.

(A) Marine support services are conducted worldwide with assets that are highly mobile. Revenues are principally derived from offshore service vessels, which regularly and routinely move from one operating area to another, often to and from offshore operating areas in different continents. Because of this asset mobility, revenues and long-lived assets attributable to the company’s international marine operations in any one country are not material. Equity in net assets of non-U.S. subsidiaries is $3.1 billion, $2.8 billion and $2.4 million at March 31, 2012, 2011 and 2010, respectively. Identifiable assets include accounts receivable and other balances denominated in currencies other than the U.S. dollar, which aggregate approximately $0.3 million, $0.5 million and $1.4 million at March 31, 2012, 2011, and 2010, respectively. These amounts are subject to the usual risks of fluctuating exchange rates and government-imposed exchange controls.

(15) GOODWILL

The company tests goodwill for impairment annually at the reporting unit level using carrying amounts as of December 31 or more frequently if events and circumstances indicate that goodwill might be impaired. The company uses the two-step method for evaluating goodwill for impairment as prescribed in ASC 350, Intangibles-Goodwill and Other (ASC 350). Step one involves comparing the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit’s carrying amount is greater than the fair value, the second step must be completed to measure the amount of impairment, if any. Step two involves calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible assets, excluding goodwill, of the reporting unit from the fair value of the reporting unit as determined in step one. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss is recognized equal to the difference. The company performed its annual impairment test as of December 31, 2010 on its then existing International and United States reporting units, and the test determined there was no goodwill impairment.

As discussed in Note (14), the company changed its reportable segments during the quarter ended September 30, 2011 from International and United States to Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The company performed an interim goodwill impairment assessment prior to changing its reportable segments and determined there was no goodwill impairment.

Goodwill of approximately $49.4 million historically assigned to the United States segment was assigned to the Americas segment. Goodwill of approximately $279.4 million historically assigned to the International segment was allocated among the new reportable segments based on their relative fair values.

The company also performed an interim goodwill impairment assessment on the new reporting units using September 30, 2011 carrying values and determined on the basis of the step one impairment test that the carrying value of its Middle East/North Africa unit exceeded its fair value thus triggering the second step of the analysis as prescribed by ASC 350. An estimated goodwill impairment charge of $30.9 million was recorded during the quarter ended September 30, 2011. Step two of the assessment was completed during the quarter ended December 31, 2011 and there was no further adjustment to goodwill.

Goodwill by reportable segment at March 31, is as follows:

(In thousands)	2012			2011
Americas	$	114,237			114,237
Asia/Pacific		56,283			56,283

Sub-Saharan Africa/Europe		127,302			127,302
	$	297,822			328,754
Goodwill, as a percentage of total assets and stockholders’ equity, at March 31, is as follows:

Goodwill as a percentage of stockholders’ equity		12	%		13%

On May 17, 2012, the company’s Board of Directors authorized the company to spend up to $200.00 million to repurchase shares of its common stock in open-market or privately-negotiated transactions. The effective date of this new authorization is July 1, 2012 through June 30, 2013. The company will use its available cash and, when considered advantageous, borrowings under its revolving credit facility or other borrowings, to fund any share repurchases.

EXHIBIT 10.46

FORM OF

INCENTIVE AGREEMENT

FOR THE GRANT OF RESTRICTED STOCK UNITS

UNDER THE

TIDEWATER INC. 2009 STOCK INCENTIVE PLAN

THIS AGREEMENT is entered into as of [•], by and between Tidewater Inc., a Delaware corporation (“Tidewater”), and [•] (the “Employee”).

WHEREAS, the Employee is a key employee of Tidewater or one of its subsidiaries and Tidewater considers it desirable and in its best interest that the Employee be given an added incentive to advance the interests of Tidewater in the form of restricted stock units payable in shares of common stock of Tidewater, $0.10 par value per share (the “Common Stock”) in accordance with the Tidewater Inc. 2009 Stock Incentive Plan (the “Plan”), which was approved by Tidewater’s stockholders at their 2009 annual meeting.

NOW, THEREFORE, in consideration of the premises, it is agreed by and between the parties as follows:

I.

Restricted Stock Units

1.1        Restricted Stock Units.    Effective on the Date of Grant, Tidewater hereby grants to the Employee an award of [•] restricted stock units (the “RSUs”) under the Plan, subject to the terms, conditions, and restrictions set forth in the Plan and in this Agreement. [•] of the RSUs shall vest based on the continued employment of the Employee as provided in Section 1.3 below (the “Time-Based RSUs”). The remaining [•] RSUs shall vest based upon continued employment and the satisfaction of performance criteria as provided in Section 1.4 below (the “Performance-Based RSUs”).

1.2        Award Restrictions.    The RSUs may not be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, whether voluntarily or involuntarily. The Employee shall have no rights, including, but not limited to, voting and dividend rights, in the shares of Common Stock underlying the RSUs unless and until such shares are issued to the Employee, or as otherwise provided in the Plan or this Agreement.

1.3        Vesting Terms – Time-Based RSUs.

(a)        Time-Based Vesting.    Upon vesting under the terms and conditions of the Plan and this Agreement, each Time-Based RSU represents the right to receive from the Company one share of Common Stock, free of any restrictions, and all amounts, securities, and property notionally credited to the Employee’s Account (as defined in Section 2.1) with respect to such Time-Based RSU.

1

(b)        Vesting Schedule.    The Time-Based RSUs shall vest in installments as follows, if, except as provided in Section 1.5, the Employee remains employed by Tidewater on such dates:

Percentage of Time-Based RSUs	Vesting Date
one-third	[•]
one-third	[•]
one-third	[•]

1.4        Vesting Terms – Performance-Based RSUs.

(a)        Performance-Based Vesting.    Upon vesting under the terms and conditions of the Plan and this Agreement, each Performance-Based RSU represents the right to receive from the Company a maximum of two shares of Common Stock, free of any restrictions, and all amounts, securities, and property notionally credited to the Employee’s Account with respect to such Performance-Based RSU.

(b)        Vesting Schedule.    Except as provided in Section 1.5, upon the Committee’s certification of the level of performance achieved, but no later than May 31, [•], depending on the three-year total shareholder return of Tidewater over the period from April 1, [•] through March 31, [•] (the “Performance Period”) as measured against peer performance over the same period, the Performance-Based RSUs shall vest and the Employee shall be entitled to receive a number of shares of Common Stock, determined as follows:

(i)        The number of Performance-Based RSUs specified in Section 1.1 represents the target award. At the end of the Performance Period, the Employee may receive a greater or lesser number of shares of Common Stock under the Plan than the number of Performance-Based RSUs granted in Section 1.1, depending on Tidewater’s Total Shareholder Return (as defined in Section 1.4(b)(iii)) ranked in terms of a percentile in relation to that of Tidewater’s Peer Group (as in Section 1.4(b)(iv)), which shall be determined as follows:

Performance Level	Tidewater’s Percentile Rank	Share Payout as a % of Performance-Based RSU Award
Maximum	³ 75th percentile	200%
Intermediate	62.5th percentile	150%
Target	50th percentile	100%
Threshold	37.5th percentile	50%
Below Threshold	£ 25th percentile	0%

2

The number of shares vesting shall be prorated if Tidewater’s rank falls between any two performance levels.

(ii)        Prior to the vesting of any Performance-Based RSUs and the payout of any shares of Common Stock under the Plan and this Agreement, the Committee shall certify in writing, by resolution or otherwise, Tidewater’s Total Shareholder Return level achieved as compared to that of the Peer Group, whether and to what extent the Performance-Based RSUs have vested, and how many shares of Common Stock are to be issued to the Employee.

(iii)        For purposes of this Agreement, “Total Shareholder Return” or “TSR” for Tidewater and each member of the Peer Group means stock price appreciation from the beginning to the end of the Performance Period, including dividends and distributions made or declared (assuming such dividends or distributions are reinvested in the common stock of Tidewater or any company in the Peer Group) during the Performance Period, expressed as a percentage return, using the following formula:

TSR = Ending Stock Price (including dividends paid) – Beginning Stock Price

Beginning Stock Price

where the “Ending Stock Price” is equal to the average closing price of the relevant stock during the final month of the Performance Period, and the “Beginning Stock Price” is equal to the average closing price of the relevant stock during the last calendar month prior to the Performance Period. TSR of Tidewater or any company in the Peer Group shall be equitably adjusted to reflect any spin-off, stock split, reverse stock split, stock dividend, recapitalization, or reclassification or other similar change in the number of outstanding shares of common stock.

(iv)        For purposes of this Agreement, Tidewater’s “Peer Group” consists of the following companies: Atwood Oceanics, Inc., Bristow Group Inc., Cameron International Corp., Diamond Offshore Drilling, Inc., Dresser-Rand Group Inc., ENSCO International Inc., Exterran Holdings Inc., FMC Technologies Inc., GulfMark Offshore, Inc., Helix Energy Solutions Group, Helmerich & Payne, Inc., Hornbeck Offshore Services Inc., Key Energy Services Inc., Kirby Corp., McDermott International Inc., Noble Energy, Inc., Oceaneering International Inc., Oil States International Inc., Overseas Shipholding Group, Precision Drilling Corporation, Pride International, Inc., Rowan Companies, Inc., SEACOR Holdings Inc., Superior Energy Services Inc., and Teekay Corp. If a member of the Peer Group is acquired or delisted during the Performance Period, that company will be excluded from the Peer Group in calculating TSR. In addition, if a company in the Peer Group declares bankruptcy, it will remain in the Peer Group until it is de-listing, but if the bankruptcy occurs after more than 50% of the Performance Period has lapsed, the date for this company will be pro-rated.

1.5        Effect of Certain Terminations.

(a)        Upon the Employee’s death or termination of employment due to Disability: (1) all Time-Based RSUs shall immediately vest and pay out in shares of Common Stock and (2) the Employee (A) shall retain a reduced pro-rata number of Performance-Based

3

RSUs, determined by multiplying the number of Performance-Based RSUs by a fraction, the numerator of which is the number of full months between the beginning of the Performance Period and the date of termination and the denominator of which is the number of months in the Performance Period, provided that the ownership of such Performance-Based RSUs shall nonetheless remain subject to all other terms and conditions of this Agreement, including the payment date described in Section 1.4(b) and the opportunity to earn a greater or lesser number of shares of Common Stock as specified in Section 1.4(b)(i), and (B) shall forfeit all other Performance-Based RSUs granted under this Agreement as of the date of termination.

(b)        In the event the Employee retires on or after age 62 with five or more years of service with the Company: (1) all Time-Based RSUs shall immediately vest and pay out in shares of Common Stock, provided that the Committee has specifically approved such action and subject to such restrictions as the Committee may impose (including, but not limited to, post-employment restrictive covenants such as non-competition, non-solicitation, and/or non-disclosure provisions) and (2) the Employee (A) shall retain a reduced pro-rata number of Performance-Based RSUs, determined by multiplying the number of Performance-Based RSUs by a fraction, the numerator of which is the number of full months between the beginning of the Performance Period and the date of termination and the denominator of which is the number of months in the Performance Period, provided that the ownership of such Performance-Based RSUs shall nonetheless remain subject to all other terms and conditions of this Agreement, including the payment date described in Section 1.4(b) and the opportunity to earn a greater or lesser number of shares of Common Stock as specified in Section 1.4(b)(i), and (B) shall forfeit all other Performance-Based RSUs granted under this Agreement as of the date of termination.

(c)        In the event of a Change of Control as provided in the Plan: (1) all Time-Based RSUs shall immediately vest and pay out in shares of Common Stock at the closing of the Change of Control and (2) the Employee shall retain the rights to all Performance-Based RSUs granted under this Agreement, provided that the vesting and payout of such Performance-Based RSUs shall nonetheless remain subject to the terms and conditions of this Agreement, including the payment date described in Section 1.4 and the opportunity to earn a greater or lesser number of shares of Common Stock as specified in Section 1.4(b)(i).

(d)        Except as otherwise expressly provided in this Section 1.5 or as otherwise determined by the Committee in its sole discretion, termination of employment shall result in forfeiture of all unvested RSUs.

II.

Dividend Equivalents and the Issuance of Shares Upon Vesting

2.1        Restricted Stock Unit Account and Dividend Equivalents.    Tidewater shall maintain an account (the “Account”) on its books in the name of the Employee. Such Account shall reflect the number of RSUs awarded to the Employee, as such number may be adjusted under the terms of the Plan and this Agreement, as well as any additional RSUs or cash credited as a result of dividend equivalents, administered as follows:

(a)        The Account shall be for recordkeeping purposes only, and no assets or other amounts shall be set aside from Tidewater’s general assets with respect to such Account.

4

(b)        If Tidewater declares a cash dividend payable any time between the Date of Grant and the date the RSUs vest and pay out under this Agreement, the Employee shall be entitled to any cash that would have been received as a dividend had the Employee’s outstanding RSUs been shares of Common Stock as of the record date with respect to which such cash dividend is to paid. Tidewater shall pay such dividend equivalents currently to the Employee on any Time-Based RSUs but shall credit such amount to the Employee’s Account with respect to any such cash dividend equivalents payable on Performance-Based RSUs.

(c)        If dividends are declared and paid in the form of shares of Common Stock rather than cash, then the Employee’s Account will be credited with one additional RSU for each share of Common Stock that would have been received as a dividend had the Employee’s outstanding RSUs been shares of Common Stock on such date.

(d)        All such cash and any additional RSUs credited via dividend equivalents shall vest or be forfeited at the same time and on the same terms as the RSUs to which they relate.

(e)        In addition, if, under Section 1.4(a)(i), the Performance-Based RSUs pay out a number of shares of Common Stock in excess of the number of Performance-Based RSUs (the “Additional Shares”), the Employee also shall be entitled to receive, simultaneous with the issuance of the Additional Shares, all dividends and distributions, whether payable in cash or Common Stock, that were payable during the Performance Period or prior to the date the Performance-Based RSUs vest and pay out under this Agreement and that the Employee would have received had he or she owned the Additional Shares on such date.

2.2        Issuance of Shares of Common Stock.    As soon as practicable following the date any RSUs vest under this Agreement, but no later than 30 days after such date, the number of shares of Common Stock to which the Employee is entitled under this Agreement shall be transferred to the Employee or his or her nominee via book entry free of restrictions and upon the Employee’s request, Tidewater shall cause a stock certificate to be issued in the name of the Employee or his or her nominee. Upon issuance of such shares, the Employee is free to hold or dispose of such shares, subject to applicable securities laws and any internal Company policy then in effect and applicable to the Employee, such as Tidewater’s Insider Trading Policy and Executive Stock Ownership Guidelines.

III.

Defined Terms

The definition of all capitalized terms used herein and not otherwise defined herein shall be as provided in the Plan.

IV.

Recovery Right of Tidewater

Tidewater has the right to recover any RSUs or shares of Common Stock issued under the Plan to the Employee, if (a) the grant, vesting, or value of such awards was based on the achievement of financial results that were subsequently the subject of a restatement; (b) the Employee is subject to Tidewater’s Executive Compensation Recovery Policy; (c) the Employee

5

engaged in intentional misconduct that caused or partially caused the need for the restatement; and (d) the effect of the restatement was to decrease the financial results such that such grant would not have been earned or would have had a lesser value. The Employee accepts the RSUs and shares of Common Stock subject to such recovery rights of Tidewater and in the event Tidewater exercises such rights, the Employee shall promptly return the RSUs or shares of Common Stock to Tidewater upon demand. If the Employee no longer holds the RSUs or shares of Common Stock at the time of demand by Tidewater, the Employee shall pay to Tidewater, without interest, all cash, securities, or other assets received by the Employee upon the sale or transfer of such shares. Tidewater may, if it chooses, effect such recovery by withholding from other amounts due to the Employee by the Company.

V.

Withholding Taxes

At any time that the Employee is required to pay to the Company an amount required to be withheld under the applicable income tax laws in connection with the vesting and payout of the RSUs, unless the Employee has previously provided the Company with payment of all applicable withholding taxes, Tidewater shall withhold, from the shares of Common Stock to be issued upon the vesting of the RSUs, shares with a value equal to the minimum statutory amount required to be withheld. The value of the shares to be withheld shall be based on the Fair Market Value of the Common Stock on the date that the amount of tax required to be withheld is determined.

VI.

No Contract of Employment Intended

Nothing in this Agreement shall confer upon the Employee any right to continue in the employment of the Company, or to interfere in any way with the right of the Company to terminate the Employee’s employment relationship with the Company at any time.

VII.

Binding Effect

This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, and successors.

VIII.

Amendment, Modification or Termination

The Committee may amend, modify, or terminate any RSUs at any time prior to vesting in any manner not inconsistent with the terms of the Plan. If the RSUs are intended to qualify as performance-based compensation under Section 162(m) of the Code, the Committee may not use its discretion to increase the compensation payable to the Employee hereunder in violation of the “performance-based compensation” requirements of Section 162(m) of the Code. Notwithstanding the foregoing, no amendment, modification, or termination may materially impair the rights of an Employee hereunder without the consent of the Employee.

6

IX.

Inconsistent Provisions

The RSUs granted hereby are subject to the provisions of the Plan, as in effect on the date hereof and as it may be amended. In the event any provision of this Agreement conflicts with such a provision of the Plan, the Plan provision shall control. The Employee acknowledges that a copy of the Plan was distributed to the Employee and that the Employee was advised to review such Plan prior to entering into this Agreement. The Employee waives the right to claim that the provisions of the Plan are not binding upon the Employee and the Employee’s heirs, executors, administrators, legal representatives, and successors.

X.

Governing Law

This Agreement shall be governed by and construed in accordance with the laws of the State of Louisiana.

XI.

Severability

If any term or provision of this Agreement, or the application thereof to any person or circumstance, shall at any time or to any extent be invalid, illegal or unenforceable in any respect as written, the Employee and Tidewater intend for any court construing this Agreement to modify or limit such provision so as to render it valid and enforceable to the fullest extent allowed by law. Any such provision that is not susceptible of such reformation shall be ignored so as to not affect any other term or provision hereof, and the remainder of this Agreement, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid, illegal or unenforceable, shall not be affected thereby and each term and provision of this Agreement shall be valid and enforced to the fullest extent permitted by law.

XII.

Entire Agreement; Modification

The Plan and the Agreement contain the entire agreement between the parties with respect to the subject matter contained herein. The Agreement may not be modified without the approval of the Committee and the Employee, except as provided in the Plan, as it may be amended from time to time in the manner provided therein, or in this Agreement, as it may be amended from time to time. Any oral or written agreements, representations, warranties, written inducements, or other communications with respect to the subject matter contained herein made prior to the execution of the Agreement shall be void and ineffective for all purposes.

(A) Marine support services are conducted worldwide with assets that are highly mobile. Revenues are principally derived from offshore service vessels, which regularly and routinely move from one operating area to another, often to and from offshore operating areas in different continents. Because of this asset mobility, revenues and long-lived assets attributable to the company's international marine operations in any one country are not material. Equity in net assets of non-U.S. subsidiaries is $3.1 billion, $2.8 billion and $2.4 million at March 31, 2012, 2011 and 2010, respectively. Identifiable assets include accounts receivable and other balances denominated in currencies other than the U.S. dollar, which aggregate approximately $0.3 million, $0.5 million and $1.4 million at March 31, 2012, 2011, and 2010, respectively. These amounts are subject to the usual risks of fluctuating exchange rates and government-imposed exchange controls.

(B) Included in Corporate are additions to properties and equipment relating to vessels currently under construction which have not yet been assigned to a non-corporate reporting segment as of the dates presented.

(C) Included in Corporate are vessels currently under construction which have not yet been assigned to a non-corporate reporting segment. The vessel construction costs will be reported in Corporate until the earlier of the vessels being assigned to a non-corporate reporting segment or the vessels' delivery. At March 31, 2012, 2011 and 2010, $249.4 million, $355.3 million and $256.3 million, respectively, of vessel construction costs are included in Corporate.

Nature Of Operations And Summary Of Significant Accounting Policies [Abstract]

Nature Of Operations

Nature of Operations

The company provides offshore service vessels and marine support services to the global offshore energy industry through the operation of a diversified fleet of offshore marine service vessels. The company's revenues, net earnings and cash flows from operations are dependent upon the activity level of the vessel fleet. Like other energy service companies, the level of the company's business activity is driven by the level of drilling and exploration activity by our customers. Our customers' activity, in turn, is dependent on crude oil and natural gas prices, which fluctuate depending on respective levels of supply and demand for crude oil and natural gas.

Principles Of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of Tidewater Inc. and its subsidiaries. Intercompany balances and transactions are eliminated in consolidation.

Use Of Estimates In Preparation Of Financial Statements

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The accompanying consolidated financial statements include estimates for allowance for doubtful accounts, useful lives of property and equipment, valuation of goodwill, income tax provisions, impairments, commitments and contingencies and certain accrued liabilities. We evaluate our estimates and assumptions on an ongoing basis based on a combination of historical information and various other assumptions that are considered reasonable under the particular circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. These accounting policies involve judgment and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions or if different assumptions had been used, as such, actual results may differ from these estimates.

Cash Equivalents

Cash Equivalents

The company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Marine Operating Supplies

Marine Operating Supplies

Marine operating supplies, which consist primarily of operating parts and supplies for the company's vessels, are stated at the lower of weighted-average cost or market.

Properties And Equipment

Properties and Equipment

Depreciation and Amortization

Properties and equipment are stated at cost. Depreciation is computed primarily on the straight-line basis beginning with the date construction is completed, with salvage values of 5%-10% for marine equipment, using estimated useful lives of 15 - 25 years for marine equipment (from date of construction) and 3 - 30 years for other properties and equipment. Depreciation is provided for all vessels unless a vessel meets the criteria to be classified as held for sale. Estimated remaining useful lives are reviewed when there has been a change in circumstances that indicates the original estimated useful life may no longer be appropriate. Upon retirement or disposal of a fixed asset, the costs and related accumulated depreciation are removed from the respective accounts and any gains or losses are included in our consolidated statements of earnings. Used equipment is depreciated in accordance with this above policy; however, no life less than six years is used for marine equipment regardless of the date constructed.

Depreciation and amortization expense for the years ended March 31, are as follows:

(In thousands)	2012		2011		2010
Depreciation expense	$	138,356		140,576		130,184

Maintenance and Repairs

Maintenance and repairs (including major repair costs) are expensed as incurred during the asset's original estimated useful life (its original depreciable life). Major repair costs incurred after the original estimated depreciable life that also have the effect of extending the useful life (for example, the complete overhaul of main engines, the replacement of mechanical components, or the replacement of steel in the vessel's hull) of the asset are capitalized and amortized over 30 months. Vessel modifications that are performed for a specific customer contract are capitalized and amortized over the firm contract term. Major modifications to equipment that are being performed not only for a specific customer contract are capitalized and amortized over the remaining life of the equipment. The majority of the company's vessels require certification inspections twice in every five year period, and the company schedules these vessel drydockings when it is anticipated that the work can be performed. While the actual length of time between drydockings can vary, we use a 30 month amortization period for the costs of these drydockings as an average time between the required certifications

Net Properties and Equipment

The following is a summary of net properties and equipment at March 31:

	2012				2011
	Number Of Vessels		Carrying Value		Number Of Vessels		Carrying Value
			(In thousands)				(In thousands)
Vessels in active service		251	$	2,567,321		262	$	2,265,042
Stacked vessels		67		34,768		90		40,224
Vessels withdrawn from service		2		633		4		673
Marine equipment and other assets under construction				261,679				358,294
Other property and equipment				41,364				37,547
Totals		320	$	2,905,765		356	$	2,701,780

The company considers a vessel to be stacked if the vessel crew is disembarked and limited maintenance is being performed on the vessel. The company reduces operating costs by stacking vessels when management does not foresee opportunities to profitably or strategically operate the vessels in the near future. Vessels are added to this list when market conditions warrant and they are removed from this list when they are returned to active service, sold or otherwise disposed. When economically practical marketing opportunities arise, the stacked vessels can be returned to service by performing any necessary maintenance on the vessel and returning fleet personnel to operate the vessel. Although not currently fulfilling charters, stacked vessels are considered to be in service and are included in the calculation of the company's utilization statistics. Stacked vessels at March 31, 2012 and 2011 have an average age of 30.9 and 30.6 years, respectively. A vast majority of vessels stacked at March 31, 2012 are currently being marketed for sale and are not expected to return to the active fleet, primarily due to their age.

Vessels withdrawn from service represent those vessels that are not included in the company's utilization statistics. Vessels withdrawn from service at March 31, 2012 and 2011 have an average age of 32.0 and 33.0 years, respectively.

All vessels are classified in the company's consolidated balance sheets in Properties and Equipment. No vessels are classified as held for sale because no vessel meets the criteria. Stacked vessels and vessels withdrawn from service are reviewed for impairment semiannually.

Impairment Of Long-Lived Assets

Impairment of Long-Lived Assets

The company reviews the vessels in its active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In such evaluation, the estimated future undiscounted cash flows generated by an asset group are compared with the carrying

amount of the asset group to determine if a write-down may be required. With respect to vessels that have not been stacked, we group together for impairment testing purposes vessels with similar operating and marketing characteristics. We also subdivide our groupings of assets with similar operating and marketing characteristics between our older vessels and newer vessels.

The company estimates cash flows based upon historical data adjusted for the company's best estimate of expected future market performance, which, in turn, is based on industry trends. If an asset group fails the undiscounted cash flow test, the company uses the discounted cash flow method to determine the estimated fair value of each asset group and compares such estimated fair value [considered Level 3, as defined by Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 360] Impairment or Disposal of Long-lived Assets, to the carrying value of each asset group in order to determine if impairment exists. If impairment exists, the carrying value of the asset group is reduced to its estimated fair value.

The primary estimates and assumptions used in reviewing active vessel groups for impairment include utilization rates, average dayrates, and average daily operating expenses. These estimates are made based on recent actual trends in utilization, dayrates and operating costs and reflect management's best estimate of expected market conditions during the period of future cash flows. These assumptions and estimates have changed considerably as market conditions have changed and they are reasonably likely to continue to change as market conditions change in the future. Although the company believes its assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce materially different results. Management estimates may vary considerably from actual outcomes due to future adverse market conditions or poor operating results that could result in the inability to recover the current carrying value of an asset group, thereby possibly requiring an impairment charge in the future. As the company's fleet continues to age, management closely monitors the estimates and assumptions used in the impairment analysis in order to properly identify evolving trends and changes in market conditions that could impact the results of the impairment evaluation.

In addition to the periodic review of its active long-lived assets for impairment when circumstances warrant, the company also performs a review of its stacked vessels and vessels withdrawn from service every six months or whenever changes in circumstances indicate that the carrying amount of a vessel may not be recoverable. Management estimates each stacked vessel's fair value by considering items such as the vessel's age, length of time stacked, likelihood of a return to active service, actual recent sales of similar vessels, among others. In certain situations we obtain an estimate of the fair value of the stacked vessel from third-party appraisers or brokers. The company records an impairment charge when the carrying value of a vessel withdrawn from service or a stacked vessel exceeds its estimated fair value. The estimates of fair value of stacked vessels are also subject to significant variability, are sensitive to changes in market conditions, and are reasonably likely to change in the future. The company has consistently recorded modest gains on the sale of stacked vessels. Refer to Note (12) for a discussion on asset impairments.

Goodwill

Goodwill

Goodwill represents the cost in excess of fair value of the net assets of companies acquired. Goodwill primarily relates to the fiscal 1998 acquisition of O.I.L. Ltd., a British company. The company tests goodwill for impairment annually at the reporting unit level using carrying amounts as of December 31 or more frequently if events and circumstances indicate that goodwill might be impaired. The company uses the two-step method for evaluating goodwill for impairment as prescribed in ASC 350, Intangibles-Goodwill and Other (ASC 350). Step one involves comparing the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit's carrying amount is greater than the fair value, the second step must be completed to measure the amount of impairment, if any. Step two involves calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible assets, excluding goodwill, of the reporting unit from the fair value of the reporting unit as determined in step one. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss is recognized equal to the difference.

As discussed in Note (15), the company changed its reportable segments during the quarter ended September 30, 2011 from International and United States to Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The company performed an interim goodwill impairment assessment prior to changing its reportable segments and determined there was no goodwill impairment.

The company also performed an interim goodwill impairment assessment on the new reporting units using September 30, 2011 carrying values and determined on the basis of the step one impairment test that the carrying value of its Middle East/North Africa unit exceeded its fair value thus triggering the second step of the analysis as prescribed by ASC 350. An estimated goodwill impairment charge of $30.9 million was recorded during the quarter ended September 30, 2011. Step two of the assessment was completed during the quarter ended December 31, 2011 and there was no further adjustment to goodwill. The company performed its annual impairment test as of December 31, 2010 on its then existing International and United States reporting units, and the test determined there was no goodwill impairment. Refer to Note (15) for a complete discussion on Goodwill.

The following table summarizes goodwill as a percentage of total assets and stockholders' equity at March 31:

	2012			2011
Goodwill as a percentage of total assets		7	%		9	%
Goodwill as a percentage of stockholders' equity		12	%		13	%

Accrued Property And Liability Losses

Accrued Property and Liability Losses

The company's insurance subsidiary establishes case-based reserves for estimates of reported losses on direct business written, estimates received from ceding reinsurers, and reserves based on past experience of unreported losses. Such losses principally relate to the company's vessel operations and are included as a component of vessel operating costs in the consolidated statements of earnings. The liability for such losses and the related reimbursement receivable from reinsurance companies are classified in the consolidated balance sheets into current and noncurrent amounts based upon estimates of when the liabilities will be settled and when the receivables will be collected.

The following table discloses the total amount of current and long-term liabilities related to accrued property and liability losses not subject to reinsurance recoverability, but considered currently payable as of March 31:

(In thousands)	2012		2011
Accrued property and liability losses	$	6,786		9,173

Pension And Other Postretirement Benefits

Pension and Other Postretirement Benefits

The company follows the provisions of ASC 715, Compensation – Retirement Benefits, and uses a March 31 measurement date for determining net periodic benefit costs, benefit obligations and the fair value of plan assets. Net periodic pension costs and accumulated benefit obligations are determined using a number of assumptions including the discount rates used to measure future obligations and expenses, the rate of compensation increases, retirement ages, mortality rates, expected long-term return on plan assets, health care cost trends, and other assumptions, all of which have a significant impact on the amounts reported.

The company's pension cost consists of service costs, interest costs, expected returns on plan assets, amortization of prior service costs or benefits and actuarial gains and losses. The company considers a number of factors in developing its pension assumptions, including an evaluation of relevant discount rates, expected long-term returns on plan assets, plan asset allocations, expected changes in wages and retirement benefits, analyses of current market conditions and input from actuaries and other consultants.

Net periodic benefit costs are based on a market-related valuation of assets equal to the fair value of assets. For the long-term rate of return, assumptions are developed regarding the expected rate of return on plan assets based on historical experience and projected long-term investment returns, which consider the plan's target asset allocation and long-term asset class return expectations. Assumptions for the discount rate use the equivalent single discount rate based on discounting expected plan benefit cash flows using the Mercer Bond Index Curve for the year ended March 31, 2012, and the Citigroup Pension Discount Curve for the years ended March 31, 2011 and 2010. For the projected compensation trend rate, short-term and long-term compensation expectations for participants, including salary increases and performance bonus payments are considered. For the health care cost trend rate for other postretirement benefits, assumptions are established for health care cost trends, applying an initial trend rate that reflects recent historical experience and broader national statistics with an ultimate trend rate that assumes that the portion of gross domestic product devoted to health care eventually becomes constant. Refer to Note (5) for a complete discussion on compensation – retirement benefits.

Income Taxes

Income Taxes

Income taxes are accounted for in accordance with the provisions of ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are not provided on undistributed earnings of certain non-U.S. subsidiaries and business ventures because the company considers those earnings to be permanently invested abroad. Refer to Note (3) for a complete discussion on income taxes.

Revenue Recognition

Revenue Recognition

The company's primary source of revenue is derived from time charter contracts of its vessels on a rate per day of service basis; therefore, vessel revenues are recognized on a daily basis throughout the contract period. These vessel time charter contracts are generally either on a term basis (average three months to two years) or on a "spot" basis. The base rate of hire for a term contract is generally a fixed rate, provided, however, that term contracts at times include escalation clauses to recover specific additional costs. A spot contract is a short-term agreement to provide offshore marine services to a customer for a specific short-term job. Spot contract terms generally range from one day to three months. Vessel revenues are recognized on a daily basis throughout the contract period. There are no material differences in the cost structure of the company's contracts based on whether the contracts are spot or term for the operating costs are generally the same without regard to the length of a contract.

Operating Costs

Operating Costs

Vessel operating costs are incurred on a daily basis and consist primarily of costs such as crew wages; repair and maintenance; insurance and loss reserves; fuel, lube oil and supplies; vessel operating leases; and other vessel expenses, which include but are not limited to costs such as brokers' commissions, training costs, agent fees, port fees, canal transit fees, temporary importation fees, vessel certification fees, and satellite communication fees. Repair and maintenance costs include both routine costs and major drydocking repair costs, which occur during the initial economic useful life of the vessel. Vessel operating costs are recognized as incurred on a daily basis.

Foreign Currency Translation

Foreign Currency Translation

The U.S. dollar is the functional currency for all of the company's existing international operations, as transactions in these operations are predominately denominated in U.S. dollars. Foreign currency exchange gains and losses are included in the consolidated statements of earnings.

Earnings Per Share

Earnings Per Share

The company follows ASC 260, Earnings Per Share. and reports both basic earnings per share and diluted earnings per share. The calculation of basic earnings per share is computed based on the weighted average number of shares of common stock outstanding. Dilutive earnings per share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share includes the dilutive effect of stock options and restricted stock grants (both time and performance based) awarded as part of the company's share-based compensation and incentive plans. Per share amounts disclosed in these Notes to Consolidated Financial Statements, unless otherwise indicated, are on a diluted basis. Refer to Note (9), Earnings Per Share.

Concentrations Of Credit Risk

Concentrations of Credit Risk

The company's financial instruments that are exposed to concentrations of credit risk consist primarily of trade and other receivables from a variety of domestic, international and national energy companies, including reinsurance companies for recoverable insurance losses. The company manages its exposure to risk by performing ongoing credit evaluations of its customers' financial condition and generally does not require collateral. The company maintains an allowance for doubtful accounts for potential losses based on expected collectability and does not believe it is generally exposed to concentrations of credit risk that are likely to have a material adverse impact on the company's financial position, results of operations, or cash flows.

Stock-Based Compensation

Stock-Based Compensation

The company follows ASC 718, Compensation – Stock Compensation, for the expensing of stock options and other share-based payments. This topic requires that stock-based compensation transactions be accounted for using a fair-value-based method. The company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards. Refer to Note (7) for a complete discussion on stock-based compensation.

Comprehensive Income

Comprehensive Income

The company reports total comprehensive income and its components in the financial statements in accordance with ASC 220, Comprehensive Income. Total comprehensive income represents the net change in stockholders' equity during a period from sources other than transactions with stockholders and, as such, includes net earnings. For the company, accumulated other comprehensive income is comprised of unrealized gains and losses on available-for-sale securities and derivative financial instruments, currency translation adjustment and any minimum pension liability for the company's U.S. Defined Benefits Pension Plan and Supplemental Executive Retirement Plan. Refer to Note (8) for a complete discussion on comprehensive income.

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities

The company periodically utilizes derivative financial instruments to hedge against foreign currency denominated assets and liabilities and currency commitments. These transactions generally include forward currency contracts or interest rate swaps that are entered into with major financial institutions. Derivative financial instruments are intended to reduce the company's exposure to foreign currency exchange risk and interest rate risk.

The company records derivative financial instruments in its consolidated balance sheets at fair value as either assets or liabilities. The accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative and the resulting designation, which is established at the inception of a derivative. The company formally documents, at the inception of a hedge, the hedging relationship and the entity's risk management objective and strategy for undertaking the hedge, including identification of the hedging instrument, the hedged item or transaction, the nature of the risk being hedged, the method used to assess effectiveness and the method that will be used to measure hedge ineffectiveness of derivative instruments that receive hedge accounting treatment.

For derivative instruments designated as foreign currency or interest rate hedges (cash flow hedge), changes in fair value, to the extent the hedge is effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. Hedge effectiveness is assessed quarterly based on the total change in the derivative's fair value. Amounts representing hedge ineffectiveness are recorded in earnings. Any change in fair value of derivative financial instruments that are speculative in nature and do not qualify for hedge accounting treatment is also recognized immediately in earnings. Proceeds received upon termination of derivative financial instruments qualifying as fair value hedges are deferred and amortized into income over the remaining life of the hedged item using the effective interest rate method.

Fair Value Measurements

Fair Value Measurements

The company follows the provisions of ASC 820, Fair Value Measurements and Disclosures, for financial assets and liabilities that are measured and reported at fair value on a recurring basis. ASC 820 establishes a hierarchy for inputs used in measuring fair value. Fair value is calculated based on assumptions that market participants would use in pricing assets and liabilities and not on assumptions specific to the entity. The statement requires that each asset and liability carried at fair value be classified into one of the following categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data

Level 3: Unobservable inputs that are not corroborated by market data

Recasted Segment Information

Recasted Segment Information

In connection with a change in reportable segments, certain prior period amounts have been recast to conform to the March 31, 2012 presentation of our segments with no effect on net earnings or retained earnings. Please refer to Note (14) – Segment and Geographical Distributions of Operations.

Reclassifications

Reclassifications

The company made certain reclassifications to prior period amounts to conform to the current year presentation. These reclassifications did not have a material effect on the consolidated statement of financial position, results of operations or cash flows.

Subsequent Events

Subsequent Events

The company evaluates subsequent events through the time of our filing on the date we issue financial statements.

Accounting Pronouncements

Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB that are adopted by the company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the company's consolidated financial statements upon adoption.

In September 2011, the FASB issued guidance on ASC 350, Intangibles-Goodwill and Other, for testing goodwill for impairment. The new guidance provides a company the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the company's assessment determines that this is the case, it is required to perform the currently prescribed two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment to be recognized for that reporting unit, if any. If the company determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required. The adoption of this guidance is effective for us beginning April 1, 2012.

In June 2011, the FASB issued guidance on ASC 220, Comprehensive Income, regarding the presentation of comprehensive income. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in stockholders' equity. Instead, a company is required to present either a continuous statement of net income and other comprehensive income or in two separate but consecutive statements. The new guidance also requires companies to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented. In December 2011, the FASB issued guidance which indefinitely defers the guidance related to the presentation of reclassification adjustments. The new guidance will be effective for us beginning April 1, 2012 and will have financial statement presentation changes only.

In May 2011, the FASB issued Accounting Standards Update No. 2011-04 ("ASU 2011-04"), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards ("IFRS") . This pronouncement was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The new guidance will be effective for us beginning April 1, 2012 and will not have a significant impact on our consolidated balance sheet, results of operations or cash flow.

The company is not liable for U.S. taxes on undistributed earnings of most of its non-U.S. subsidiaries and business ventures that it considers indefinitely reinvested abroad because the company adopted the provisions of the American Jobs Creation Act of 2004 (the Act) effective April 1, 2005. All previously recorded deferred tax assets and liabilities related to temporary differences, foreign tax credits, or prior undistributed earnings of these entities whose future and prior earnings were anticipated to be indefinitely reinvested abroad were reversed in March 2005.

The effective tax rate applicable to pre-tax earnings for the years ended March 31, is as follows:

	2012		2011		2010
Effective tax rate applicable to pre-tax earnings	21.28	%	28.68	%	3.08	%

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at March 31, is as follows:

(In thousands)		2012		2011
Deferred tax assets:
Financial provisions not deducted for tax purposes	$	31,960		26,964
Net operating loss and tax credit carryforwards		32,054		15,446
Other		76		34
Gross deferred tax assets		64,090		42,444
Less valuation allowance		—		—
Net deferred tax assets		64,090		42,444
Deferred tax liabilities:
Depreciation and amortization		(214,627	)	(216,319	)
Other		—		(416	)
Gross deferred tax liabilities		(214,627	)	(216,735	)
Net deferred tax liabilities	$	(150,537	)	(174,291	)

The company has not recognized a U.S. deferred tax liability associated with temporary differences related to investments in foreign subsidiaries that are essentially permanent in duration. The differences relate primarily to undistributed earnings and stock basis differences. Though the company does not anticipate repatriation of funds, a current U.S. tax liability would be recognized when the company receives those foreign funds in a taxable manner such as through receipt of dividends or sale of investments. A determination of the unrecognized deferred tax liability for temporary differences related to investments in foreign subsidiaries is not practicable due to uncertainty regarding the use of foreign tax credits which would become available as a result of a transaction.

The amount of foreign income that U.S. deferred taxes has not been recognized upon, as of March 31, is as follows:

(In thousands)		2012
Foreign income not recognized for U.S. deferred taxes	$	1,874,875

The company has the following foreign tax credit carry-forwards that begin to expire in 2015 and net operating loss carry-forwards that begin to expire in 2031 as of March 31:

(In thousands)		2012
Foreign tax credit carry-forwards	$	13,759
Net operating loss carry-forwards		52,270

The company's balance sheet reflects the following in accordance with ASC 740, Income Taxes at March 31:

(In thousands)		2012	2011
Tax liabilities for uncertain tax positions	$	14,281	18,469
Income tax payable		22,217	11,911

The tax liabilities for uncertain tax positions are attributable to a permanent establishment issue related to a foreign joint venture. Penalties and interest related to income tax liabilities are included in income tax expense. Income tax payable is included in other current liabilities.

Unrecognized tax benefits, which would lower the effective tax rate if realized, at March 31, are as follows:

(In thousands)		2012
Unrecognized tax benefit related to state tax issues	$	8,657
Interest receivable on unrecognized tax benefit related to state tax issues		50

In January 2008, the U.S. District Court for the Eastern District of Louisiana issued a ruling in the company's favor with respect to a motion for summary judgment concerning the IRS disallowance of the company's tax deduction for foreign sales corporation commissions for fiscal years 1999 and 2000. In April 2009, the Fifth Circuit Court of Appeals affirmed the District Court's judgment. The IRS did not appeal the Court of Appeals ruling, resulting in final resolution of the issue in the company's favor in July 2009. The tax benefit related to the issue is approximately $36.1 million, or $0.70 per common share, for fiscal year ended March 31, 2010, which primarily includes a reversal of previously recorded liabilities for uncertain tax positions and interest income on the judgment.

In March 2010, the company settled a state tax issue for fiscal years 2001 through 2003, which resulted in a tax benefit of $2.9 million, including interest of $0.8 million.

A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended March 31, are as follows:

(In thousands)		2012		2011		2010
Balance at April 1,	$	15,220		14,691		44,875
Additions based on tax positions related to the current year		2,813		2,130		2,198
Reductions for tax positions of prior years		(1,375	)	(1,601	)	(2,774	)
Exchange rate fluctuation		—		—		(930	)
Settlement and lapse of statute of limitations		(931	)	—		(28,678	)
Balance at March 31,	$	15,727		15,220		14,691
With limited exceptions, the company is no longer subject to tax audits by United States (U.S.) federal, state, local or foreign taxing authorities for years prior to 2004. The company has ongoing examinations by various state and foreign tax authorities and does not believe that the results of these examinations will have a material adverse effect on the company's financial position or results of operations.
The company receives a tax benefit that is generated by certain employee stock benefit plan transactions. This benefit is recorded directly to additional paid-in-capital and does not reduce the company's effective income tax rate. The tax benefit for the years ended March 31, are as follows:
(In thousands)		2012		2011		2010
Excess tax benefits on stock options exercised	$	738		1,190		72

[1] Marine support services are conducted worldwide with assets that are highly mobile. Revenues are principally derived from offshore service vessels, which regularly and routinely move from one operating area to another, often to and from offshore operating areas in different continents. Because of this asset mobility, revenues and long-lived assets attributable to the company's international marine operations in any one country are not material. Equity in net assets of non-U.S. subsidiaries is $3.1 billion, $2.8 billion and $2.4 million at March 31, 2012, 2011 and 2010, respectively. Identifiable assets include accounts receivable and other balances denominated in currencies other than the U.S. dollar, which aggregate approximately $0.3 million, $0.5 million and $1.4 million at March 31, 2012, 2011, and 2010, respectively. These amounts are subject to the usual risks of fluctuating exchange rates and government-imposed exchange controls.

[2] Operating income consists of revenues less operating costs and expenses, depreciation, goodwill impairment, general and administrative expenses and gain on asset dispositions, net, of the company's operations. Goodwill impairment by quarter for fiscal 2012 and Gain on asset dispositions, net, by quarter for fiscal 2012 and 2011, are as follows:

[3] Included in Corporate are additions to properties and equipment relating to vessels currently under construction which have not yet been assigned to a non-corporate reporting segment as of the dates presented.

[4] Included in Corporate are vessels currently under construction which have not yet been assigned to a non-corporate reporting segment. The vessel construction costs will be reported in Corporate until the earlier of the vessels being assigned to a non-corporate reporting segment or the vessels' delivery. At March 31, 2012, 2011 and 2010, $249.4 million, $355.3 million and $256.3 million, respectively, of vessel construction costs are included in Corporate.

Nature Of Operations And Summary Of Significant Accounting Policies [Abstract]

Nature Of Operations And Summary Of Significant Accounting Policies

(1) NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

The company provides offshore service vessels and marine support services to the global offshore energy industry through the operation of a diversified fleet of offshore marine service vessels. The company's revenues, net earnings and cash flows from operations are dependent upon the activity level of the vessel fleet. Like other energy service companies, the level of the company's business activity is driven by the level of drilling and exploration activity by our customers. Our customers' activity, in turn, is dependent on crude oil and natural gas prices, which fluctuate depending on respective levels of supply and demand for crude oil and natural gas.

Principles of Consolidation

The consolidated financial statements include the accounts of Tidewater Inc. and its subsidiaries. Intercompany balances and transactions are eliminated in consolidation.

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The accompanying consolidated financial statements include estimates for allowance for doubtful accounts, useful lives of property and equipment, valuation of goodwill, income tax provisions, impairments, commitments and contingencies and certain accrued liabilities. We evaluate our estimates and assumptions on an ongoing basis based on a combination of historical information and various other assumptions that are considered reasonable under the particular circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. These accounting policies involve judgment and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions or if different assumptions had been used, as such, actual results may differ from these estimates.

Cash Equivalents

The company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Marine Operating Supplies

Marine operating supplies, which consist primarily of operating parts and supplies for the company's vessels, are stated at the lower of weighted-average cost or market.

Properties and Equipment

Depreciation and Amortization

Properties and equipment are stated at cost. Depreciation is computed primarily on the straight-line basis beginning with the date construction is completed, with salvage values of 5%-10% for marine equipment, using estimated useful lives of 15 - 25 years for marine equipment (from date of construction) and 3 - 30 years for other properties and equipment. Depreciation is provided for all vessels unless a vessel meets the criteria to be classified as held for sale. Estimated remaining useful lives are reviewed when there has been a change in circumstances that indicates the original estimated useful life may no longer be appropriate. Upon retirement or disposal of a fixed asset, the costs and related accumulated depreciation are removed from the respective accounts and any gains or losses are included in our consolidated statements of earnings. Used equipment is depreciated in accordance with this above policy; however, no life less than six years is used for marine equipment regardless of the date constructed.

Depreciation and amortization expense for the years ended March 31, are as follows:

(In thousands)	2012		2011		2010
Depreciation expense	$	138,356		140,576		130,184

Maintenance and Repairs

Maintenance and repairs (including major repair costs) are expensed as incurred during the asset's original estimated useful life (its original depreciable life). Major repair costs incurred after the original estimated depreciable life that also have the effect of extending the useful life (for example, the complete overhaul of main engines, the replacement of mechanical components, or the replacement of steel in the vessel's hull) of the asset are capitalized and amortized over 30 months. Vessel modifications that are performed for a specific customer contract are capitalized and amortized over the firm contract term. Major modifications to equipment that are being performed not only for a specific customer contract are capitalized and amortized over the remaining life of the equipment. The majority of the company's vessels require certification inspections twice in every five year period, and the company schedules these vessel drydockings when it is anticipated that the work can be performed. While the actual length of time between drydockings can vary, we use a 30 month amortization period for the costs of these drydockings as an average time between the required certifications

Net Properties and Equipment

The following is a summary of net properties and equipment at March 31:

	2012				2011
	Number Of Vessels		Carrying Value		Number Of Vessels		Carrying Value
			(In thousands)				(In thousands)
Vessels in active service		251	$	2,567,321		262	$	2,265,042
Stacked vessels		67		34,768		90		40,224
Vessels withdrawn from service		2		633		4		673
Marine equipment and other assets under construction				261,679				358,294
Other property and equipment				41,364				37,547
Totals		320	$	2,905,765		356	$	2,701,780

The company considers a vessel to be stacked if the vessel crew is disembarked and limited maintenance is being performed on the vessel. The company reduces operating costs by stacking vessels when management does not foresee opportunities to profitably or strategically operate the vessels in the near future. Vessels are added to this list when market conditions warrant and they are removed from this list when they are returned to active service, sold or otherwise disposed. When economically practical marketing opportunities arise, the stacked vessels can be returned to service by performing any necessary maintenance on the vessel and returning fleet personnel to operate the vessel. Although not currently fulfilling charters, stacked vessels are considered to be in service and are included in the calculation of the company's utilization statistics. Stacked vessels at March 31, 2012 and 2011 have an average age of 30.9 and 30.6 years, respectively. A vast majority of vessels stacked at March 31, 2012 are currently being marketed for sale and are not expected to return to the active fleet, primarily due to their age.

Vessels withdrawn from service represent those vessels that are not included in the company's utilization statistics. Vessels withdrawn from service at March 31, 2012 and 2011 have an average age of 32.0 and 33.0 years, respectively.

All vessels are classified in the company's consolidated balance sheets in Properties and Equipment. No vessels are classified as held for sale because no vessel meets the criteria. Stacked vessels and vessels withdrawn from service are reviewed for impairment semiannually.

Impairment of Long-Lived Assets

The company reviews the vessels in its active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In such evaluation, the estimated future undiscounted cash flows generated by an asset group are compared with the carrying

amount of the asset group to determine if a write-down may be required. With respect to vessels that have not been stacked, we group together for impairment testing purposes vessels with similar operating and marketing characteristics. We also subdivide our groupings of assets with similar operating and marketing characteristics between our older vessels and newer vessels.

The company estimates cash flows based upon historical data adjusted for the company's best estimate of expected future market performance, which, in turn, is based on industry trends. If an asset group fails the undiscounted cash flow test, the company uses the discounted cash flow method to determine the estimated fair value of each asset group and compares such estimated fair value [considered Level 3, as defined by Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 360] Impairment or Disposal of Long-lived Assets, to the carrying value of each asset group in order to determine if impairment exists. If impairment exists, the carrying value of the asset group is reduced to its estimated fair value.

The primary estimates and assumptions used in reviewing active vessel groups for impairment include utilization rates, average dayrates, and average daily operating expenses. These estimates are made based on recent actual trends in utilization, dayrates and operating costs and reflect management's best estimate of expected market conditions during the period of future cash flows. These assumptions and estimates have changed considerably as market conditions have changed and they are reasonably likely to continue to change as market conditions change in the future. Although the company believes its assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce materially different results. Management estimates may vary considerably from actual outcomes due to future adverse market conditions or poor operating results that could result in the inability to recover the current carrying value of an asset group, thereby possibly requiring an impairment charge in the future. As the company's fleet continues to age, management closely monitors the estimates and assumptions used in the impairment analysis in order to properly identify evolving trends and changes in market conditions that could impact the results of the impairment evaluation.

In addition to the periodic review of its active long-lived assets for impairment when circumstances warrant, the company also performs a review of its stacked vessels and vessels withdrawn from service every six months or whenever changes in circumstances indicate that the carrying amount of a vessel may not be recoverable. Management estimates each stacked vessel's fair value by considering items such as the vessel's age, length of time stacked, likelihood of a return to active service, actual recent sales of similar vessels, among others. In certain situations we obtain an estimate of the fair value of the stacked vessel from third-party appraisers or brokers. The company records an impairment charge when the carrying value of a vessel withdrawn from service or a stacked vessel exceeds its estimated fair value. The estimates of fair value of stacked vessels are also subject to significant variability, are sensitive to changes in market conditions, and are reasonably likely to change in the future. The company has consistently recorded modest gains on the sale of stacked vessels. Refer to Note (12) for a discussion on asset impairments.

Goodwill

Goodwill represents the cost in excess of fair value of the net assets of companies acquired. Goodwill primarily relates to the fiscal 1998 acquisition of O.I.L. Ltd., a British company. The company tests goodwill for impairment annually at the reporting unit level using carrying amounts as of December 31 or more frequently if events and circumstances indicate that goodwill might be impaired. The company uses the two-step method for evaluating goodwill for impairment as prescribed in ASC 350, Intangibles-Goodwill and Other (ASC 350). Step one involves comparing the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit's carrying amount is greater than the fair value, the second step must be completed to measure the amount of impairment, if any. Step two involves calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible assets, excluding goodwill, of the reporting unit from the fair value of the reporting unit as determined in step one. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss is recognized equal to the difference.

As discussed in Note (15), the company changed its reportable segments during the quarter ended September 30, 2011 from International and United States to Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The company performed an interim goodwill impairment assessment prior to changing its reportable segments and determined there was no goodwill impairment.

The company also performed an interim goodwill impairment assessment on the new reporting units using September 30, 2011 carrying values and determined on the basis of the step one impairment test that the carrying value of its Middle East/North Africa unit exceeded its fair value thus triggering the second step of the analysis as prescribed by ASC 350. An estimated goodwill impairment charge of $30.9 million was recorded during the quarter ended September 30, 2011. Step two of the assessment was completed during the quarter ended December 31, 2011 and there was no further adjustment to goodwill. The company performed its annual impairment test as of December 31, 2010 on its then existing International and United States reporting units, and the test determined there was no goodwill impairment. Refer to Note (15) for a complete discussion on Goodwill.

The following table summarizes goodwill as a percentage of total assets and stockholders' equity at March 31:

	2012			2011
Goodwill as a percentage of total assets		7	%		9	%
Goodwill as a percentage of stockholders' equity		12	%		13	%

Accrued Property and Liability Losses

The company's insurance subsidiary establishes case-based reserves for estimates of reported losses on direct business written, estimates received from ceding reinsurers, and reserves based on past experience of unreported losses. Such losses principally relate to the company's vessel operations and are included as a component of vessel operating costs in the consolidated statements of earnings. The liability for such losses and the related reimbursement receivable from reinsurance companies are classified in the consolidated balance sheets into current and noncurrent amounts based upon estimates of when the liabilities will be settled and when the receivables will be collected.

The following table discloses the total amount of current and long-term liabilities related to accrued property and liability losses not subject to reinsurance recoverability, but considered currently payable as of March 31:

(In thousands)	2012		2011
Accrued property and liability losses	$	6,786		9,173

Pension and Other Postretirement Benefits

The company follows the provisions of ASC 715, Compensation – Retirement Benefits, and uses a March 31 measurement date for determining net periodic benefit costs, benefit obligations and the fair value of plan assets. Net periodic pension costs and accumulated benefit obligations are determined using a number of assumptions including the discount rates used to measure future obligations and expenses, the rate of compensation increases, retirement ages, mortality rates, expected long-term return on plan assets, health care cost trends, and other assumptions, all of which have a significant impact on the amounts reported.

The company's pension cost consists of service costs, interest costs, expected returns on plan assets, amortization of prior service costs or benefits and actuarial gains and losses. The company considers a number of factors in developing its pension assumptions, including an evaluation of relevant discount rates, expected long-term returns on plan assets, plan asset allocations, expected changes in wages and retirement benefits, analyses of current market conditions and input from actuaries and other consultants.

Net periodic benefit costs are based on a market-related valuation of assets equal to the fair value of assets. For the long-term rate of return, assumptions are developed regarding the expected rate of return on plan assets based on historical experience and projected long-term investment returns, which consider the plan's target asset allocation and long-term asset class return expectations. Assumptions for the discount rate use the equivalent single discount rate based on discounting expected plan benefit cash flows using the Mercer Bond Index Curve for the year ended March 31, 2012, and the Citigroup Pension Discount Curve for the years ended March 31, 2011 and 2010. For the projected compensation trend rate, short-term and long-term compensation expectations for participants, including salary increases and performance bonus payments are considered. For the health care cost trend rate for other postretirement benefits, assumptions are established for health care cost trends, applying an initial trend rate that reflects recent historical experience and broader national statistics with an ultimate trend rate that assumes that the portion of gross domestic product devoted to health care eventually becomes constant. Refer to Note (5) for a complete discussion on compensation – retirement benefits.

Income Taxes

Income taxes are accounted for in accordance with the provisions of ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are not provided on undistributed earnings of certain non-U.S. subsidiaries and business ventures because the company considers those earnings to be permanently invested abroad. Refer to Note (3) for a complete discussion on income taxes.

Revenue Recognition

The company's primary source of revenue is derived from time charter contracts of its vessels on a rate per day of service basis; therefore, vessel revenues are recognized on a daily basis throughout the contract period. These vessel time charter contracts are generally either on a term basis (average three months to two years) or on a "spot" basis. The base rate of hire for a term contract is generally a fixed rate, provided, however, that term contracts at times include escalation clauses to recover specific additional costs. A spot contract is a short-term agreement to provide offshore marine services to a customer for a specific short-term job. Spot contract terms generally range from one day to three months. Vessel revenues are recognized on a daily basis throughout the contract period. There are no material differences in the cost structure of the company's contracts based on whether the contracts are spot or term for the operating costs are generally the same without regard to the length of a contract.

Operating Costs

Vessel operating costs are incurred on a daily basis and consist primarily of costs such as crew wages; repair and maintenance; insurance and loss reserves; fuel, lube oil and supplies; vessel operating leases; and other vessel expenses, which include but are not limited to costs such as brokers' commissions, training costs, agent fees, port fees, canal transit fees, temporary importation fees, vessel certification fees, and satellite communication fees. Repair and maintenance costs include both routine costs and major drydocking repair costs, which occur during the initial economic useful life of the vessel. Vessel operating costs are recognized as incurred on a daily basis.

Foreign Currency Translation

The U.S. dollar is the functional currency for all of the company's existing international operations, as transactions in these operations are predominately denominated in U.S. dollars. Foreign currency exchange gains and losses are included in the consolidated statements of earnings.

Earnings Per Share

The company follows ASC 260, Earnings Per Share. and reports both basic earnings per share and diluted earnings per share. The calculation of basic earnings per share is computed based on the weighted average number of shares of common stock outstanding. Dilutive earnings per share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share includes the dilutive effect of stock options and restricted stock grants (both time and performance based) awarded as part of the company's share-based compensation and incentive plans. Per share amounts disclosed in these Notes to Consolidated Financial Statements, unless otherwise indicated, are on a diluted basis. Refer to Note (9), Earnings Per Share.

Concentrations of Credit Risk

The company's financial instruments that are exposed to concentrations of credit risk consist primarily of trade and other receivables from a variety of domestic, international and national energy companies, including reinsurance companies for recoverable insurance losses. The company manages its exposure to risk by performing ongoing credit evaluations of its customers' financial condition and generally does not require collateral. The company maintains an allowance for doubtful accounts for potential losses based on expected collectability and does not believe it is generally exposed to concentrations of credit risk that are likely to have a material adverse impact on the company's financial position, results of operations, or cash flows.

Stock-Based Compensation

The company follows ASC 718, Compensation – Stock Compensation, for the expensing of stock options and other share-based payments. This topic requires that stock-based compensation transactions be accounted for using a fair-value-based method. The company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards. Refer to Note (7) for a complete discussion on stock-based compensation.

Comprehensive Income

The company reports total comprehensive income and its components in the financial statements in accordance with ASC 220, Comprehensive Income. Total comprehensive income represents the net change in stockholders' equity during a period from sources other than transactions with stockholders and, as such, includes net earnings. For the company, accumulated other comprehensive income is comprised of unrealized gains and losses on available-for-sale securities and derivative financial instruments, currency translation adjustment and any minimum pension liability for the company's U.S. Defined Benefits Pension Plan and Supplemental Executive Retirement Plan. Refer to Note (8) for a complete discussion on comprehensive income.

Derivative Instruments and Hedging Activities

The company periodically utilizes derivative financial instruments to hedge against foreign currency denominated assets and liabilities and currency commitments. These transactions generally include forward currency contracts or interest rate swaps that are entered into with major financial institutions. Derivative financial instruments are intended to reduce the company's exposure to foreign currency exchange risk and interest rate risk.

The company records derivative financial instruments in its consolidated balance sheets at fair value as either assets or liabilities. The accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative and the resulting designation, which is established at the inception of a derivative. The company formally documents, at the inception of a hedge, the hedging relationship and the entity's risk management objective and strategy for undertaking the hedge, including identification of the hedging instrument, the hedged item or transaction, the nature of the risk being hedged, the method used to assess effectiveness and the method that will be used to measure hedge ineffectiveness of derivative instruments that receive hedge accounting treatment.

For derivative instruments designated as foreign currency or interest rate hedges (cash flow hedge), changes in fair value, to the extent the hedge is effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. Hedge effectiveness is assessed quarterly based on the total change in the derivative's fair value. Amounts representing hedge ineffectiveness are recorded in earnings. Any change in fair value of derivative financial instruments that are speculative in nature and do not qualify for hedge accounting treatment is also recognized immediately in earnings. Proceeds received upon termination of derivative financial instruments qualifying as fair value hedges are deferred and amortized into income over the remaining life of the hedged item using the effective interest rate method.

Fair Value Measurements

The company follows the provisions of ASC 820, Fair Value Measurements and Disclosures, for financial assets and liabilities that are measured and reported at fair value on a recurring basis. ASC 820 establishes a hierarchy for inputs used in measuring fair value. Fair value is calculated based on assumptions that market participants would use in pricing assets and liabilities and not on assumptions specific to the entity. The statement requires that each asset and liability carried at fair value be classified into one of the following categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data

Level 3: Unobservable inputs that are not corroborated by market data

Recasted Segment Information

In connection with a change in reportable segments, certain prior period amounts have been recast to conform to the March 31, 2012 presentation of our segments with no effect on net earnings or retained earnings. Please refer to Note (14) – Segment and Geographical Distributions of Operations.

Reclassifications

The company made certain reclassifications to prior period amounts to conform to the current year presentation. These reclassifications did not have a material effect on the consolidated statement of financial position, results of operations or cash flows.

Subsequent Events

The company evaluates subsequent events through the time of our filing on the date we issue financial statements.

Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB that are adopted by the company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the company's consolidated financial statements upon adoption.

In September 2011, the FASB issued guidance on ASC 350, Intangibles-Goodwill and Other, for testing goodwill for impairment. The new guidance provides a company the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the company's assessment determines that this is the case, it is required to perform the currently prescribed two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment to be recognized for that reporting unit, if any. If the company determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required. The adoption of this guidance is effective for us beginning April 1, 2012.

In June 2011, the FASB issued guidance on ASC 220, Comprehensive Income, regarding the presentation of comprehensive income. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in stockholders' equity. Instead, a company is required to present either a continuous statement of net income and other comprehensive income or in two separate but consecutive statements. The new guidance also requires companies to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented. In December 2011, the FASB issued guidance which indefinitely defers the guidance related to the presentation of reclassification adjustments. The new guidance will be effective for us beginning April 1, 2012 and will have financial statement presentation changes only.

In May 2011, the FASB issued Accounting Standards Update No. 2011-04 ("ASU 2011-04"), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards ("IFRS") . This pronouncement was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The new guidance will be effective for us beginning April 1, 2012 and will not have a significant impact on our consolidated balance sheet, results of operations or cash flow.

Commitments And Contingencies

(11) COMMITMENTS AND CONTINGENCIES

Compensation Commitments

Compensation continuation agreements exist with all of the company's officers whereby each receives compensation and benefits in the event that their employment is terminated following certain events relating to a change in control of the company. The maximum amount of cash compensation that could be paid under the agreements, based on present salary levels, is approximately $39.9 million.

Vessel Commitments

The table below summarizes the company's various vessel commitments to acquire and construct new vessels, by vessel type, as of March 31, 2012:

(In thousands, except vessel count)	Number of Vessels		Total Cost		Invested Through 3/31/12		Remaining Balance 03/31/12
Vessels under construction:
Anchor handling towing supply		2	$	47,584		37,839		9,745
Platform supply vessels		15		488,388		195,738		292,650
Crewboats		5		22,369		10,969		11,400
Total vessels under construction		22		558,341		244,546		313,795
Vessels to be purchased:
Platform supply vessels		3		58,387		12,891		45,496
Total vessels to be purchased		3		58,387		12,891		45,496
Total vessel commitments		25	$	616,728		257,437		359,291

The total cost of the various vessel new-build commitments includes contract costs and other incidental costs. The company has vessels under construction at a number of different shipyards around the world (with one of these vessels being constructed in the United States by the company's wholly-owned shipyard, Quality Shipyards, L.L.C.). The anchor handling towing supply vessels under construction have 8,200 brake horsepower (BHP), while the platform supply vessels (PSV) under construction range between 1,900 and 6,360 deadweight tons of cargo capacity. Scheduled delivery for the new-build vessels began in April 2012, with delivery of the final new-build vessel expected in May 2014.

Regarding the vessels to be purchased, the company took possession of one PSV in April 2012 that has 3,000 deadweight tons of cargo capacity for a total cost of $19.8 million. The company plans to take possession of the remaining two PSVs, which have 3,500 deadweight tons of cargo capacity, in July 2012 and in September 2012 for a total aggregate cost of $38.6 million. As of March 31, 2012, the company had invested $12.9 million for the acquisition of these three vessels.

The company's vessel construction program has been designed to replace over time the company's older fleet of vessels with fewer, larger and more efficient vessels, while also opportunistically revamping the size and capabilities of the company's fleet. The company anticipates using future operating cash flows, existing borrowing capacity and new borrowings or lease arrangements to fund current and future commitments in connection with the fleet renewal and modernization program. The company continues to evaluate its fleet renewal program, whether through new construction or acquisitions, relative to other investment opportunities and uses of cash, including the current share repurchase authorization, and in the context of current conditions in the credit and capital markets.

The company generally requires shipyards to provide third party credit support in the event that vessels are not completed and delivered in accordance with the terms of the shipbuilding contracts. That third party credit support typically guarantees the return of amounts paid by the company, and generally takes the form of refundment guarantees or standby letters of credit issued by major financial institutions located in the country of the shipyard. While the company seeks to minimize its shipyard credit risk by requiring these instruments, the ultimate return of amounts paid by the company in the event of shipyard default is still subject to the creditworthiness of the shipyard and the provider of the credit support, as well as the company's ability to successfully pursue legal action to compel payment of these instruments. When third party credit support is not available or cost effective, the company endeavors to limit its credit risk by requiring cash deposits and through other contract terms with the shipyard and other counterparties.

Currently the company is experiencing substantial delay with one fast, crew/supply boat under construction in Brazil that was originally scheduled to be delivered in September 2009. On April 5, 2011, pursuant to the vessel construction contract, the company sent the subject shipyard a letter initiating arbitration in order to resolve disputes of such matters as the shipyard's failure to achieve payment milestones, its failure to follow the construction schedule, and its failure to timely deliver the vessel. The company believes that the shipyard has suspended construction of the vessel. The company continues to pursue that arbitration. The company has third party credit support in the form of insurance coverage for 90% of the progress payments made on this vessel, or all but approximately $2.4 million of the carrying value of the accumulated costs through March 31, 2012.

In March 2012, the company terminated four PSV construction projects in Indonesia due to unjustified delays beyond the agreed delivery dates. The vessels were originally scheduled to deliver between May and November 2012, but had projected delivery dates ranging from August to December 2013 at the time the projects were terminated. The company had refundment guarantees in place supporting the progress payments that were made on these vessels and received the full refund including interest. During November and December of 2011, the company canceled its purchase agreements with the same shipyard for two anchor handling towing supply vessels under construction in Indonesia. The cancellations, which were due to unjustified delays beyond the agreed delivery dates, were authorized under the purchase agreements. No deposits or progress payments were involved in these two cancellations.

Two vessels under construction at a domestic shipyard have fallen substantially behind schedule. The shipyard recently notified the company that the shipyard should be entitled to a delay in the delivery date for both vessels and an increase in the contract price for the first vessel because the company was late in completing and providing the shipyard with the vessel's detailed design drawings. The detailed design drawings were developed for the company by a third party designer. While the company believes that other factors also contributed to the delay, negotiations with the shipyard are ongoing in an attempt to reach an amicable settlement of these issues. These negotiations are at a preliminary stage.

Completion of Internal Investigation and Settlements with United States and Nigerian Agencies

The company has previously reported that special counsel engaged by the company's Audit Committee had completed an internal investigation into certain Foreign Corrupt Practices Act (FCPA) matters and reported its findings to the Audit Committee. The substantive areas of the internal investigation have been reported publicly by the company in prior filings.

Special counsel has reported to the Department of Justice (DOJ) and the Securities and Exchange Commission (SEC) the results of the investigation, and the company has entered into separate agreements with the two agencies to resolve the matters reported by special counsel. The company has previously reported the principal terms of these agreements.

Securities and Exchange Commission

As previously reported, the company reached an agreement with the SEC to resolve its previously disclosed investigation of possible violations of the FCPA. Under the agreement, the company consented to the filing in federal district court of a complaint ("SEC Complaint") by the SEC against Tidewater Inc., without admitting or denying the allegations in the SEC Complaint, and to the entry by the court of a final judgment and permanent injunction. On November 8, 2010, a federal district court entered a final judgment approving the agreement.

The agreement required Tidewater Inc. to pay a total of approximately $11.4 million, consisting of $8.4 million (principally representing disgorgement of profits and prejudgment interest) payable at the time of settlement and a contingent civil penalty of $3.0 million. The contingent civil penalty was to be payable to the SEC in the event that the company had not otherwise agreed within 18 months of the date the court entered judgment to pay fines or penalties of at least that amount to another United States government authority (or authorities) in connection with the matters covered by the SEC Complaint. Given the agreement reached with the DOJ (discussed below), no contingent civil penalty was required to be paid to the SEC. The full $11.4 million financial charge associated with the settlement with the SEC, however, was recorded in the fourth quarter of fiscal 2010 and was included in general and administrative expenses. The $8.4 million settlement was paid to the SEC in the third quarter of fiscal 2011 after the federal district court approved the agreement.

Department of Justice

The company reached an agreement with the DOJ to resolve its previously disclosed investigation of possible violations of the FCPA. Under the agreement, Tidewater Marine International Inc. ("TMII"), a wholly-owned subsidiary of the company organized in the Cayman Islands, and the DOJ entered into a Deferred Prosecution Agreement ("DPA"). Pursuant to the DPA, the DOJ deferred criminal charges against TMII for a period of three years and seven days from the date of judicial approval of the Agreement, in return for: (a) TMII's acceptance of responsibility for, and agreement not to contest or contradict the truthfulness of, the statement of facts and allegations contained in a three-count criminal information to be filed concurrently with the DPA; (b) TMII's payment of a $7.35 million fine, (c) TMII's and Tidewater Inc.'s compliance with certain undertakings relating to compliance with the FCPA and other applicable laws in connection with the Company's operations, and cooperation with domestic and foreign authorities in connection with the matters that are the subject of the DPA; (d) TMII's and Tidewater Inc.'s agreement to continue to address any deficiencies in the company's internal controls, policies and procedures relating to compliance with the FCPA and other applicable anti-corruption laws, if and to the extent not already addressed; and (e) Tidewater Inc.'s agreement to report to the DOJ in writing annually for the term of the DPA regarding remediation of the matters that are the subject of the DPA, the implementation of any enhanced internal controls, and any evidence of improper payments the company may have discovered during the term of the DPA. Tidewater submitted its first annual report to the DOJ in November 2011.

If TMII and Tidewater Inc. comply with the DPA during its term, the DOJ will not bring the charges set out in the information. In the event TMII or Tidewater Inc. breaches the DPA, the DOJ has discretion to extend its term for up to a year, or bring certain criminal charges against TMII as outlined in the DPA.

A federal district court accepted the DPA on November 9, 2010. In the quarter ended December 31, 2010, TMII paid the $7.35 million fine. Implementation of the DOJ settlement eliminated the $3.0 million contingent civil penalty in connection with the SEC civil settlement detailed above. An additional financial charge of $4.35 million associated with the DOJ settlement was recorded during the quarter ended September 30, 2010 and was included in general and administrative expenses.

Settlement with the Nigerian Government

The company announced on March 3, 2011, that it had reached an agreement with the Federal Government of Nigeria ("FGN") to settle and resolve the previously disclosed investigation by the FGN. As part of that agreement, one of the company's Nigerian subsidiaries agreed to pay $6.0 million to the FGN and to pay an additional $0.3 million for the FGN's attorneys' fees and other expenses. The total $6.3 million ($0.12 per diluted common share) settlement payments were recorded and paid during the quarter ended March 31, 2011.

Merchant Navy Officers Pension Fund

A current subsidiary of the company is a participating employer in an industry-wide multi-employer retirement fund in the United Kingdom, known as the Merchant Navy Officers Pension Fund (MNOPF). The company has been informed by the Trustee of the MNOPF that the Fund has a deficit that will require contributions from the participating employers. The amount and timing of the company's share of the fund's deficit depends on a number of factors, including updated calculations of the total fund deficit, theories of contribution imposed as determined by and within the scope of the Trustee's authority, the number of then participating solvent employers, and the final formula adopted to allocate the required contribution among such participating employers. The amount payable to MNOPF based on assessments was $6.7 million and $9.6 million at March 31, 2012 and 2011, respectively, all of which has been accrued. The company recorded $0.3 million and $6.0 million of additional liabilities during fiscal 2012 and 2011 respectively. No additional liabilities were recorded during fiscal 2010. Payments totaling $3.1 million and $0.9 million were paid to the fund during fiscal 2012 and 2011 respectively. In the future, the fund's Trustee may claim that the company owes additional amounts for various reasons, including negative fund investment returns or the inability of other assessed participating employers to contribute their share of respective allocations, failing which, the company and other solvent participating employers will be asked for additional contributions. In October 2010, the Trustee advised the company of its intention to accelerate previously agreed installment payments for the company and other participating employers in the scheme. The company objected to that decision and has reached an agreement in principle with the Trustee to pay the total remaining assessments (aggregating $6.7 million as of March 31, 2012) in installments through October 2014. This agreement in principle is subject to final confirmation by the company and the Trustee.

Sonatide Joint Venture

The company has previously announced that its existing Sonatide joint venture agreement with Sonangol had been extended to May 31, 2012 to allow ongoing joint venture restructuring negotiations to continue.

The company has from time to time also provided updates regarding the status of its continuing negotiations with Sonangol to put its Sonatide joint venture on a more permanent footing after a number of temporary extensions of the original joint venture agreement. As previously disclosed, in March 2012, Sonangol informed Tidewater that it would not permit further vessel contracting activity by Sonatide until the joint venture negotiations had been resolved to the parties' mutual satisfaction. As a result, the company has begun deploying vessels (at prevailing market day rates) to other markets as those vessels become available.

The company has recently exchanged proposals and is continuing discussions with Sonangol. In the most recent meeting between the two negotiating teams, only modest progress was made in the restructuring negotiations, and important and fundamental issues regarding the restructured relationship remain outstanding and unresolved. In that meeting, Sonangol and the company discussed a number of topics, up to and including the potential issues associated with a wind up of the existing joint venture in the event restructuring discussions are not ultimately successful. If negotiations relating to putting the Sonatide joint venture on a more permanent footing are ultimately unsuccessful, the company will work toward an orderly wind up of the joint venture. We believe, however, that the joint venture would be allowed to honor existing vessel charter agreements through their contract terms. Even though the global market for offshore supply vessels appears to be well balanced (and the market for deepwater supply vessels is currently strong), there would be financial impacts associated with the wind up of the existing joint venture and the possible redeployment of vessels to other markets, including mobilization costs and costs to redeploy Tidewater shore-based employees to other areas, in addition to lost revenues associated with potential downtime between vessel contracts. These financial impacts could, individually or in the aggregate, be material to our results of operations and cash flows. If there is a need to redeploy vessels which are currently deployed in Angola to other international markets, Tidewater believes that there is sufficient demand for these vessels at prevailing market day rates.

For the year ended March 31, 2012, Tidewater's Angolan operations generated vessel revenues of approximately $254 million, or 24% of its consolidated vessel revenue, from an average of approximately 93 vessels (14 of which were stacked on average in fiscal 2012), and, for the year ended March 31, 2011, generated vessel revenues of approximately $237 million, or 23% of consolidated vessel revenue, from an average of approximately 97 vessels (13 of which were stacked on average in fiscal 2011). As of March 31, 2012, the carrying value of Tidewater's investment in the Sonatide joint venture, which is included in "Investments in, at equity, and advances to unconsolidated companies," is approximately $46 million.

Brazilian Customs

In April 2011, two Brazilian subsidiaries of Tidewater were notified by the Customs Office in Macae, Brazil that they were jointly and severally being assessed fines of 155.0 million Brazilian reais (approximately $90.3 million as of March 31, 2012). The assessment of these fines is for the alleged failure of these subsidiaries to obtain import licenses with respect to 17 Tidewater vessels that provided Brazilian offshore vessel services to Petrobras, the Brazilian national oil company, over a three-year period ending December 2009. After consultation with its Brazilian tax advisors, Tidewater and its Brazilian subsidiaries believe that vessels that provide services under contract to the Brazilian offshore oil and gas industry are deemed, under applicable law and regulations, to be temporarily imported into Brazil, and thus exempt from the import license requirement. The Macae Customs Office has now, without a change in the underlying applicable law or regulations, taken the position that the temporary importation exemption is only available to new, and not used, goods imported into Brazil and therefore it was improper for the company to deem its vessels as being temporarily imported. The fines have been assessed based on this new interpretation of Brazilian customs law taken by the Macae Customs Office. After consultation with its Brazilian tax advisors, the company believes that the assessment is without legal justification and that the Macae Customs Office has misinterpreted applicable Brazilian law on duties and customs. The company is vigorously contesting these fines (which it has neither paid nor accrued for) and, based on the advice of its Brazilian counsel, believes that it has a high probability of success with respect to the overturn of the entire amount of the fines, either at the administrative appeal level or, if necessary, in Brazilian courts. In December 2011, an administrative appeals board issued a decision that disallowed 149.0 million Brazilian reais (approximately $86.8 million as of March 31, 2012) of the total fines sought by the Macae Customs Office. The full decision is subject to further administrative appellate review, and the company understands that this further full review by a secondary appellate board is ongoing. The company is contesting the decision with respect to the remaining 6.0 million Brazilian reais (approximately $3.5 million as of March 31, 2012) in fines. The company believes that the ultimate resolution of this matter will not have a material effect on the consolidated financial statements.

Potential for Future Brazilian State Tax Assessment

The company is aware that a Brazilian state in which the company has operations has notified two of the company's competitors that they are liable for unpaid taxes (and penalties and interest thereon) for failure to pay state import taxes with respect to vessels that such competitors operate within the coastal waters of such state pursuant to charter agreements. The import tax being asserted is equal to a percentage (which could be as high as 16% for vessels entering that state's waters prior to December 31, 2010 and 3% thereafter) of the affected vessels' declared values. The company understands that the two companies involved are contesting the assessment through administrative proceedings before the taxing authority.

To date, the company's two Brazilian subsidiaries, as well as vessels for all other competitors (more than a hundred competitors), have not been similarly notified by the Brazilian state that it has an import tax liability related to its vessel activities imported through that state. Although the company has been advised by its Brazilian tax counsel that substantial defenses would be available if a similar tax claim were asserted against the company, if an import tax claim were to be asserted, it could be for a substantial amount given that the company has had substantial and continuing operations within the territory of the state (although the amount could fluctuate significantly depending on the administrative determination of the taxing authority as to the rate to apply, the vessels subject to the levy and the time periods covered). In addition, under certain circumstances, the company might be required to post a bond or other adequate security in the amount of the assessment (plus any interest and penalties) if it became necessary to challenge the assessment in a Brazilian court. The statute of limitations for the Brazilian state to levy an assessment of the import tax is five years from the date of a vessel's entry into Brazil. The company has not yet determined the potential tax assessment, and according to the Brazilian tax counsel, chances of defeating a possible claim/notification from the State authorities in court are probable. To obtain legal certainty and predictability for future charter agreements and because the company was importing two vessels to start new charters in Brazil, the company filed two suits on August 22, 2011 and April 5, 2012, respectively, against the Brazilian state and judicially deposited the respective state tax for these newly imported vessels. As of March 31, 2012, no accrual has been recorded for any liability associated with any potential future assessment for previous periods based on management's assessment, after consultation with Brazilian counsel, that a liability for such taxes was not probable.

Venezuelan Operations

The company has previously reported that in May 2009 the Venezuelan National Assembly enacted a law (the Reserve Law) whereby the Bolivarian Republic of Venezuela (Venezuela) reserved to itself assets and services related to maritime activities on Lake Maracaibo. The company also previously reported that in May 2009, Petróleos de Venezuela, S.A. (PDVSA), the Venezuelan national oil company, invoking the Reserve Law, took possession of (a) 11 of the company's vessels that were then supporting PDVSA operations in the Lake Maracaibo region, (b) the company's shore-based facility adjacent to Lake Maracaibo and (c) certain other related assets. The company has also previously reported that in July 2009, Petrosucre, S.A. (Petrosucre), a subsidiary of PDVSA, took control of four additional company vessels. As a consequence of these measures, the company (i) no longer has possession or control of those assets, (ii) no longer operates them or provides support for their operations, and (iii) no longer has any other vessels or operations in Venezuela.

As a result of the May 2009 seizure of the 11 vessels and other assets discussed above, the company recorded a charge of $3.75 million ($2.9 million after tax, or $0.06 per common share), during the quarter ended June 30, 2009, to write off the net book value of the assets seized. As a result of the July 2009 vessel seizures, the company recorded a charge of $0.5 million ($0.4 million after tax, or $0.01 per common share) during the quarter ended September 30, 2009, to write off the net book value of those assets.

As a result of the asset seizures referred to above, the lack of further operations in Venezuela, and the continuing uncertainty about the timing and amount of the compensation that the company may collect in the future (including compensation for the taking of the accounts receivable payable by PDVSA and Petrosucre), the company recorded a $44.8 million ($44.8 million after tax, or $0.87 per common share) provision during the quarter ended June 30, 2009, to fully reserve accounts receivable payable by PDVSA and Petrosucre.

As previously reported by the company, the company filed with the International Centre for Settlement of Investment Disputes (ICSID) a Request for Arbitration against the Republic of Venezuela seeking compensation for the expropriation of the company's Venezuelan investments. On January 24, 2011, the arbitration tribunal, appointed under the ICSID Convention to resolve the investment dispute, held its first session on procedural issues in Washington, D.C. The arbitration tribunal established a briefing and hearing schedule related to jurisdictional issues. The briefing and hearings on jurisdiction concluded on March 1, 2012. The company expects the arbitration tribunal to issue a written ruling on jurisdictional issues in the second half of 2012. To the extent that the arbitration tribunal finds a basis for jurisdiction over this dispute, the company intends to continue diligently to prosecute its claim in the arbitration. While the company believes, after consultation with its advisors, that it is entitled to full reparation for the losses suffered as a result of the actions taken by the Republic, there can be no assurances that the company will prevail in the arbitration.

Currency Devaluation and Fluctuation Risk

Due to the company's global operations, the company is exposed to foreign currency exchange rate fluctuations and exchange rate risks on all charter hire contracts denominated in foreign currencies. For some of our non-U.S. contracts, a portion of the revenue and local expenses are incurred in local currencies with the result that the company is at risk of changes in the exchange rates between the U.S. dollar and foreign currencies. 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. To minimize the financial impact of these items, the company attempts to contract a significant majority of its services in U.S. dollars. In addition, the company attempts to minimize its financial impact of these risks, by matching the currency of the company's operating costs with the currency of the revenue streams when considered appropriate. The company continually monitors the currency exchange risks associated with all contracts not denominated in U.S. dollars.

Legal Proceedings

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.

Fair Value Measurements And Disclosures

(12) FAIR VALUE MEASUREMENTS AND DISCLOSURES

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Other Financial Instruments

The company's primary financial instruments consist of cash and cash equivalents, trade receivables and trade payables with book values that are considered to be representative of their respective fair values. The company periodically utilizes derivative financial instruments to hedge against foreign currency denominated assets and liabilities, currency commitments, or to lock in desired interest rates. These transactions are generally spot or forward currency contracts or interest rate swaps that are entered into with major financial institutions. Derivative financial instruments are intended to reduce the company's exposure to foreign currency exchange risk and interest rate risk. The company enters into derivative instruments only to the extent considered necessary to address its risk management objectives and does not use derivative contracts for speculative purposes. The derivative instruments are recorded at fair value using quoted prices and quotes obtainable from the counterparties to the derivative instruments.

Cash Equivalents. The company's cash equivalents, which are securities with maturities less than 90 days, are held in money market funds or time deposit accounts with highly rated financial institutions. The carrying value for cash equivalents is considered to be representative of its fair value due to the short duration and conservative nature of the cash equivalent investment portfolio.

Spot Derivatives. Spot derivative financial instruments are short-term in nature and generally settle within two business days. The fair value of spot derivatives approximates the carrying value due to the short-term nature of this instrument, and as a result, no gains or losses are recognized.

The company had one foreign exchange spot contract outstanding at March 31, 2012, which totaled a notional value of $1.0 million. The one spot contract settled by April 2, 2012. The company had eight purchase and one sell foreign exchange spot contracts outstanding at March 31, 2011, which totaled an aggregate notional value of $3.6 million. All nine spot contracts settled by April 4, 2011.

Forward Derivatives. Forward derivative financial instruments are generally longer-term in nature but generally do not exceed one year. The accounting for gains or losses on forward contracts is dependent on the nature of the risk being hedged and the effectiveness of the hedge.

At March 31, 2012, the company had four British pound forward contracts outstanding, which is generally intended to hedge the company's foreign exchange exposure relating to its MNOPF liability as disclosed in Note (11) and elsewhere in this document. The forward contracts expire at various times through March 2013. The combined change in fair value of the forward contracts was approximately $0.1 million, all of which was recorded as a foreign exchange gain during the fiscal year ended March 31, 2012, because the forward contracts did not qualify as hedge instruments. All changes in fair value of the forward contracts were recorded in earnings.

At March 31, 2011, the company had three British pound forward contracts outstanding, related to the company's foreign exchange exposure on its MNOPF liability. The combined change in fair value of these forward contracts at March 31, 2011 was approximately $0.3 million, all of which was recorded as a foreign exchange gain during the fiscal year ended March 31, 2011, because the forward contracts did not qualify as hedge instruments.

The following table provides the fair value hierarchy for the company's other financial instruments measured as of March 31, 2012:

(In thousands)	Total		Quoted prices in active markets (Level 1)		Significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Asset Impairments

The company accounts for long-lived assets in accordance with ASC 360-10-35, Impairment or Disposal of Long-Lived Assets. The company reviews the vessels in its active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In such evaluation the estimated future undiscounted cash flows generated by an asset group are compared with the carrying amount of the asset group to determine if a write-down may be required. With respect to vessels that have not been stacked, we group together for impairment testing purposes vessels with similar operating and marketing characteristics. We also subdivide our groupings of assets with similar operating and marketing characteristics between our older vessels and newer vessels.

The company estimates cash flows based upon historical data adjusted for the company's best estimate of expected future market performance, which, in turn, is based on industry trends. If an asset group fails the undiscounted cash flow test, the company uses the discounted cash flow method to determine the estimated fair value of each asset group and compares such estimated fair value (considered Level 3, as defined by ASC 360) to the carrying value of each asset group in order to determine if impairment exists. If impairment exists, the carrying value of the asset group is reduced to its estimated fair value.

In addition to the periodic review of its active long-lived assets for impairment when circumstances warrant, the company also performs a review of its stacked vessels and vessels withdrawn from service every six months or whenever changes in circumstances indicate that the carrying amount of a vessel may not be recoverable. Management estimates each stacked vessel's fair value by considering items such as the vessel's age, length of time stacked, likelihood of a return to active service, actual recent sales of similar vessels, among others. In certain situations we obtain an estimate of the fair value of the stacked vessel from third-party appraisers or brokers. The company records an impairment charge when the carrying value of a vessel withdrawn from service or a stacked vessel exceeds its estimated fair value. The estimates of fair value of stacked vessels are also subject to significant variability, are sensitive to changes in market conditions, and are reasonably likely to change in the future.

The below table summarizes the combined fair value of the assets that incurred impairments along with the amount of impairment during the years ended March 31. The impairment charges were recorded in gain on asset dispositions, net.

Amount of impairment incurred	$	3,607		8,958		3,102

[1] Marine support services are conducted worldwide with assets that are highly mobile. Revenues are principally derived from offshore service vessels, which regularly and routinely move from one operating area to another, often to and from offshore operating areas in different continents. Because of this asset mobility, revenues and long-lived assets attributable to the company's international marine operations in any one country are not material. Equity in net assets of non-U.S. subsidiaries is $3.1 billion, $2.8 billion and $2.4 million at March 31, 2012, 2011 and 2010, respectively. Identifiable assets include accounts receivable and other balances denominated in currencies other than the U.S. dollar, which aggregate approximately $0.3 million, $0.5 million and $1.4 million at March 31, 2012, 2011, and 2010, respectively. These amounts are subject to the usual risks of fluctuating exchange rates and government-imposed exchange controls.

Employee Retirement Plans [Abstract]

Employee Retirement Plans

(5) EMPLOYEE RETIREMENT PLANS

U.S. Defined Benefit Pension Plan

The company has a defined benefit pension plan (pension plan) that covers certain U.S. citizen employees and employees who are permanent residents of the United States. Benefits are based on years of service and employee compensation. In December 2009, the Board of Directors amended the pension plan to discontinue the accrual of benefits once the plan was frozen on December 31, 2010. On that date, previously accrued pension benefits under the pension plan were frozen for the approximately 60 active employees who participated in the plan. This change did not affect benefits earned by participants prior to January 1, 2011. The active employees who participated in the pension plan have become participants in the company's defined contribution retirement plan effective January 1, 2011. These changes are providing the company more predictable retirement plan costs and cash flows. By changing to a defined contribution plan and freezing the benefits accrued under the predecessor defined benefit plan, the company's future benefit obligations and requirements for cash contributions for the frozen pension plan are reduced. Losses associated with the curtailment of the pension plan were immaterial. No amounts were contributed to the plan during fiscal 2012 and 2011. The company does not expect to contribute to the plan during fiscal 2013.

Supplemental Executive Retirement Plan

The company also offers a supplemental retirement plan (supplemental plan) that provides pension benefits to certain employees in excess of those allowed under the company's tax-qualified pension plan. Assets of this non-contributory defined benefit plan are held in a Rabbi Trust, invested in a variety of marketable securities, none of which is Tidewater stock. The Rabbi Trust assets are recorded at fair value with unrealized gains or losses included in other comprehensive income. Effective March 4, 2010, the supplemental plan was closed to new participation. The company did not contribute to the Rabbi Trust during fiscal 2012 and 2011. No decision has been made as to any funding to be completed during fiscal 2013. The supplemental plan is a non-qualified plan and, as such, the company is not required to make contributions to the supplemental plan.

Investments held in a Rabbi Trust for the benefit of participants in the supplemental plan are included in other assets. The following table summarizes the carrying value of the trust assets, including unrealized gains or losses at March 31:

(In thousands)	2012		2011
Investments held in Rabbi Trust	$	17,366		18,043
Unrealized gains in carrying value of trust assets		251		523
Unrealized gains in carrying value of trust assets are net of income tax expense of		135		281
Obligations under the supplemental plan		30,633		26,197

The unrealized gains or losses in the carrying value of the trust assets, net of income tax expense, are included in accumulated other comprehensive income (other stockholders' equity). To the extent that trust assets are liquidated to fund benefit payments, gains or losses, if any, will be recognized at that time. The company's obligations under the supplemental plan are included in 'accrued expenses' and 'other liabilities and deferred credits' on the consolidated balance sheet.

The supplemental plan was amended in December 2008 to allow participants the option to elect a lump sum benefit in lieu of other payment options currently provided by the plan. As a result of the amendment, certain participants received a lump sum distribution in July 2009 in settlement of the supplemental plan obligation. The aggregate payment to those participants electing the lump sum distribution in July 2009 was $8.7 million. A settlement loss of $3.6 million was recorded in general and administrative expenses during fiscal 2010.

Postretirement Benefit Plan

Qualified retired employees currently are covered by a program which provides limited health care and life insurance benefits. Costs of the program are based on actuarially determined amounts and are accrued over the period from the date of hire to the full eligibility date of employees who are expected to qualify for these benefits. This plan is funded through payments as benefits are required.

Investment Strategies

Pension Plan

The obligations of our pension plan are supported by assets held in a trust for the payment of future benefits. The company is obligated to adequately fund the trust. For the pension plan assets, the company has the following primary investment objectives: (1) closely match the cash flows from the plan's investments from interest payments and maturities with the payment obligations from the plan's liabilities; (2) closely match the duration of plan assets with the duration of plan liabilities and (3) enhance the plan's investment returns without taking on undue risk by industries, maturities or geographies of the underlying investment holdings.

If the plan assets are less than the plan liabilities, the pension plan assets will be invested exclusively in fixed income debt securities. Any investments in corporate bonds shall be at least investment grade, while mortgage and asset-backed securities must be rated "A" or better. If an investment is placed on credit watch, or is downgraded to a level below the investment grade, the holding will be liquidated, even at a loss, in a reasonable time period. The plan will only hold investments in equity securities if the plan assets exceed the estimated plan liabilities.

The cash flow requirements of the pension plan will be analyzed at least annually. Portfolio repositioning will be required when material changes to the plan liabilities are identified and when opportunities arise to better match cash flows with the known liabilities. Additionally, trades will occur when opportunities arise to improve the yield-to-maturity or credit quality of the portfolio.

The company's policy for the pension plan is to contribute no less than the minimum required contribution by law and no more than the maximum deductible amount. The plan does not invest in Tidewater stock.

Supplemental Plan

The investment policy of the supplemental plan is to assess the historical returns and risk associated with alternative investment strategies to achieve an expected rate of return on plan assets. The objectives of the plan are designed to maximize total returns within prudent parameters of risk for a retirement plan of this type. The below table summarizes the supplemental plan's minimum and maximum rate of return objectives for plan assets:

	Minimum Expected Rate of Return on Plan Assets	Maximum Expected Rate of Return on Plan Assets
Equity securities	5%	7%
Debt securities	1%	3%
Cash and cash equivalents	0%	1%

Whereas fluctuating rates of return are characteristic of the securities markets, the investment objective of the supplemental plan is to achieve investment returns sufficient to meet the actuarial assumptions. This is defined as an investment return greater than the current actuarial discount rate assumption of 4.75%, which is subject to annual upward or downward revisions. The below table summarizes the supplemental plan's minimum and maximum market value objectives for plan assets, which are based upon a five to ten year investment horizon:

	Minimum Market Value Objective for Plan Assets	Maximum Market Value Objective for Plan Assets
Equity securities	55%	75%
Debt securities	25%	45%
Percentage of debt securities allowed in below investment grade bonds	0%	20%
Cash and cash equivalents	0%	10%

Equity holdings shall be restricted to issues of corporations that are actively traded on the major U.S. exchanges and NASDAQ. Debt security investments may include all securities issued by the U.S. Treasury or other federal agencies and investment grade corporate bonds. When a particular asset class exceeds its minimum or maximum allocation ranges, rebalancing will be addressed upon review of the quarterly performance reports and as cash contributions and withdrawals are made.

Pension and Supplemental Plan Asset Allocations

The following table provides the target and actual asset allocations for the pension plan and the supplemental plan:

	Target			Actual as of 2012			Actual as of 2011
Pension plan:
Equity securities		—			—			—
Debt securities		100	%		97	%		98	%
Cash and other		—			3	%		2	%
Total		100	%		100	%		100	%
Supplemental plan:
Equity securities		65	%		63	%		64	%
Debt securities		35	%		32	%		29	%
Cash and other		—			5	%		7	%
Total		100	%		100	%		100	%

Significant Concentration Risks

The pension plan and the supplemental plan assets are periodically evaluated for concentration risks. As of March 31, 2012, the company did not have any individual asset investments that comprised 10% or more of each plan's overall assets.

The pension plan assets are primarily invested in debt securities with no more than the greater of 5% of the fixed income portfolio or $2.5 million being invested in the securities of a single issuer, except investments in U.S. Treasury and other federal agency obligations. In the event that plan assets exceed the estimated plan liabilities for the pension plan, up to two times the difference between the plan assets and plan liabilities may be invested in equity securities, and so long as equities do not exceed 15% of the market value of the assets. The investment policy sets forth that the maximum single investment of the equity portfolio is 5% of the portfolio market value. Further, investments in foreign securities are restricted to American Depository Receipts (ADR) and stocks listed on the U.S. stock exchanges and may not exceed 10% of the equity portfolio.

The current diversification policy for the supplemental plan sets forth that equity securities in any single industry sector shall not exceed 25% of the equity portfolio market value and shall not exceed 10% market value of the equity portfolio for equity holdings in any single corporation. Additionally, debt securities should be diversified between issuers within each sector with no one issuer comprising more than 10% of the aggregate fixed income portfolio, excluding issues of the U.S. Treasury or other federal agencies.

To develop the expected long-term rate of return on assets assumption, the company considered the current level of expected returns on various asset classes. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected return on plan assets assumption for the portfolio.

Based upon the assumptions used to measure the company's qualified pension and postretirement benefit obligation at March 31, 2012, including pension and postretirement benefits attributable to estimated future employee service, the company expects that benefits to be paid over the next ten years will be as follows:

	(In thousands)
Year ending March 31,	Pension Benefits		Other Benefits
2013		$        7,862		1,453
2014		15,569		1,522
2015		5,082		1,636
2016		5,255		1,672
2017		5,416		1,794
2018 – 2022		28,368		9,948
Total 10-year estimated future benefit payments		$      67,552		18,025

Health Care Cost Trends

The assumed health care cost trend rate used in measuring the accumulated postretirement benefit obligation at March 31, 2012 was 9.1% for pre-65 medical and prescription drug coverage and 7.0% for post-65 medical coverage; gradually declining to 4.5% in the year 2029. The assumed health care cost trend rate used in measuring the net periodic postretirement benefit cost for the year ended March 31, 2012 was 9.5% for pre-65 medical and prescription drug coverage and 7.0% for post-65 medical coverage; gradually declining to 4.5% in the year 2029. The health care cost trend rate used in measuring the net periodic postretirement benefit cost for fiscal 2013 is expected to be 9.1% for pre-65 medical and prescription drug coverage and 7.0% for post-65 medical coverage.

A 1% increase in the assumed health care cost trend rates for each year would increase the accumulated postretirement benefit obligation by approximately $3.9 million at March 31, 2012 and increase the total of service and interest cost for the year ended March 31, 2012 by $0.3 million. A 1% decrease in the assumed health care cost trend rates for each year would decrease the accumulated postretirement benefit obligation by approximately $3.2 million at March 31, 2012 and decrease the total of service and interest cost for the year ended March 31, 2012 by $0.2 million.

Defined Contribution Plans

Retirement Plan

A defined contribution retirement plan covers all eligible U.S. fleet personnel, along with all new eligible employees of the company hired after December 31, 1995. Effective January 1, 2011, the active employees who participated in the now frozen defined benefit pension plan have become participants in the company's defined contribution retirement plan. This plan is noncontributory by the employee, but the company contributes, in cash, 3% of an eligible employee's compensation to a trust on behalf of the employees. The active employees who participated in the now frozen defined benefit pension plan may receive an additional 1% to 8% depending on age and years of service. Company contributions vest over five years.

401(k) Plan

Upon meeting various citizenship, age and service requirements, employees are eligible to participate in a defined contribution savings plan and can contribute from 2% to 75% of their base salary to an employee benefit trust. The company matches with company common stock 50% of the first 8% of eligible compensation deferred by the employee. Company contributions vest over six years.

The plan held the following number of shares of Tidewater common stock as of March 31:

	2012		2011
Number of shares of Tidewater common stock held by 401(k) plan		256,816		288,200

The amounts charged to expense related to the above defined contribution plans, for the fiscal years ended March 31, are as follows:

(In thousands)	2012		2011		2010
Defined contribution plans expense, net of forfeitures		$        3,120		2,985		2,674
Defined contribution plans forfeitures		335		154		568

Other Plans

A non-qualified supplemental savings plan is provided to executive officers who have the opportunity to defer up to 50% of their eligible compensation that cannot be deferred under the existing 401(k) plan due to IRS limitations. A company match may be provided on these contributions equal to 50% of the first 8% of eligible compensation deferred by the employee to the extent the employee is not able to receive the full amount of company match to the 401(k) plan due to IRS limitations. The plan also allows participants to defer up to 100% of their bonuses. In addition, an amount equal to any refunds that must be made due to the failure of the 401(k) nondiscrimination test may be deferred into this plan.

Effective March 4, 2010, the non-qualified supplemental savings plan was modified to allow the company to contribute restoration benefits to eligible employees. Employees who do not accrue a benefit in the supplemental executive retirement plan and who are eligible for a contribution in the defined contribution retirement plan automatically become eligible for the restoration benefit when the employee's eligible retirement compensation exceeds the section 401(a)(17) limit. The restoration benefit is noncontributory by the employee, but the company contributes, in cash, 3% of an eligible employee's compensation above the 401(a)(17) limit to a trust on behalf of the employees. The active employees who participated in the now frozen defined benefit pension plan receive an additional 1% to 8% depending on age and years of service.

The company also provides a multinational savings plan to eligible non-U.S. citizen employees working outside their respective country of origin and who have been employed for one year of continuous service with the company. Participants of the plan may contribute 1% to 15% of their base salary. The company matches, in cash, 50% of the first 6% of eligible compensation deferred by the employee. Company contributions vest over six years.

The amounts charged to expense related to the multinational pension savings plan contributions, for the fiscal years ended March 31, are as follows:

(In thousands)	2012		2011		2010
Multinational pension savings plan expense		$        415		438		438

The company also provides certain benefits programs which are maintained in several other countries that provide retirement income for covered employees.

Stock-Based Compensation And Incentive Plans [Abstract]

Stock-Based Compensation And Incentive Plans

(7) STOCK-BASED COMPENSATION AND INCENTIVE PLANS

General

The company's employee stock option, restricted stock awards, restricted stock units (that settle in Tidewater common stock), and phantom stock plans are long-term retention plans that are intended to attract, retain and provide incentives for talented employees, including officers and non-employee directors, and to align stockholder and employee interests. The company believes its employee stock option plans are critical to its operations and productivity. The employee stock option plans allow the company to grant, on a discretionary basis, both incentive and non-qualified stock options as well as restricted stock.

Under the company's stock option and restricted stock plans, the Compensation Committee of the Board of Directors has the authority to grant stock options, restricted shares and restricted stock units of the company's stock to officers and other key employees. Under the terms of the plans, stock options are granted with an exercise price equal to the stock's closing fair market value on the date of grant.

The number of common stock shares reserved for issuance under the plans and the number of shares available for future grants at March 31, are as follows:

	March 31, 2012
Shares of common stock reserved for issuance under the plans		2,611,678
Shares of common stock available for future grants		886,254

Stock Option Plans

The company has granted stock options to its directors and employees, including officers, under several different stock incentive plans. Generally, options granted vest annually over a three-year vesting period measured from the date of grant. Options not previously exercised expire at the earlier of either three months after termination of the grantee's employment or ten years after the date of grant. Upon retirement, unvested stock options are forfeited. The retiree has two years post retirement to exercise vested options. All of the stock options are classified as equity awards.

The company uses the Black-Scholes option-pricing model to determine the fair value of options granted and to calculate the share-based compensation expense. Stock options were not granted during fiscal 2012. The fair value and assumptions used for the stock options issued for the following years ended March 31, are as follows:

	2011		2010
Weighted average fair value of stock options granted		$15.92		$14.87
Risk-free interest rate		2.66%		2.66%
Expected dividend yield		2.19%		2.19%
Expected stock price volatility		38.40%		38.40%
Expected stock option life		6.0 years		6.0 years

The following table sets forth a summary of stock option activity of the company for fiscal years 2012, 2011 and 2010:

The aggregate intrinsic value of the options outstanding at March 31, 2012 was $17.4 million. The aggregate intrinsic value of options exercisable at March 31, 2012 was $16.0 million.
Stock option compensation expense along with the reduction effect on basic and diluted earnings per share, and stock option compensation expense for the years ended March 31, are as follows:
(In thousands, except per share data)	2012		2011		2010

Basic earnings per share reduced by		0.05		0.07		0.05
Diluted earnings per share reduced by		0.05		0.07		0.05

As of March 31, 2012, total unrecognized stock-option compensation costs amounted to $2.2 million or $1.6 million net of tax. No stock option compensation costs were capitalized as part of the cost of an asset. Compensation costs for stock options that have not yet vested will be recognized as the underlying stock options vest over the appropriate future period. The level of unrecognized stock-option compensation will be affected by any future stock option grants and by the termination of any employee who has received stock options that are unvested as of the employee's termination date.

Restricted Stock Awards

The company has granted restricted stock awards to key employees, including officers, under several different employee stock plans, which provide for the granting of restricted stock and/or performance awards to officers and key employees. The company awards both time-based and performance-based shares of restricted stock awards. The restrictions on the time-based restricted stock awards lapse generally over a four year period and require no goals to be achieved other than the passage of time and continued employment. The restrictions on the performance-based restricted stock award lapse if the company meets specific targets. During the restricted period, the restricted shares may not be transferred or encumbered, but the recipient has the right to vote the restricted shares and receive dividends on the time-based restricted shares. Dividends are accrued on performance-based restricted shares and ultimately paid only if the performance criteria is achieved. All of the restricted stock awards are classified as equity awards in stockholders' equity. The deferred amount is generally amortized on a straight-line basis to earnings over the respective vesting periods and is net of forfeitures.

The following table sets forth a summary of restricted stock award activity of the company for fiscal 2012, 2011 and 2010:

As of March 31, 2012, total unrecognized restricted stock compensation costs amounted to $24.4 million, or $17.0 million net of tax. No restricted stock award compensation costs were capitalized as part of the costs of an asset. The amount of unrecognized restricted stock compensation will be affected by any future restricted stock grants and by the separation of an employee from the company who has received restricted stock grants that are unvested as of their separation date. There were no modifications to the restricted stock awards during fiscal 2012.

Restricted Stock Units

The company has granted restricted stock units to key employees, including officers, under the company's employee stock plan, which provide for the granting of restricted stock units to officers and key employees. The company awards time-based units, where each unit represents the right to receive, at the end of a vesting period, one unrestricted share of Tidewater common stock with no exercise price. The company also awards performance-based restricted stock units, where each unit represents the right to receive, at the end of a vesting period, up to two shares of Tidewater common stock with no exercise price. The company uses assumptions underlying the Black-Scholes methodology to produce a Monte Carlo simulation model to value the performance-based restricted stock units. The fair value of the time-based restricted stock units is based on the market price of our common stock on the date of grant. Vesting of the performance-based restricted stock units is based on the company's three year Total Shareholder Return (TSR) as measured against a three year TSR of a defined peer group. The restrictions on the time-based restricted stock units lapse over a three year period from the date of the award and require no goals to be achieved other than the passage of time and continued employment. The restrictions on the performance-based restricted stock units lapse if the company meets specific targets as defined. During the restricted period, the restricted stock units may not be transferred or encumbered, but the recipient has the right to receive dividend equivalents on the restricted stock units, but have no voting rights until the units vest. Dividend equivalents are accrued on performance-based restricted shares and ultimately paid only if the performance criteria is achieved. Upon retirement, the Compensation Committee of the Board of Directors will take into consideration the accelerated vesting of the restricted stock units after certain age and service criteria are met. Restricted stock unit compensation costs are recognized on a straight-line basis over the vesting period, and are net of forfeitures.

The following table sets forth a summary of restricted stock unit activity of the company for fiscal 2012:

The amount of unrecognized restricted stock unit compensation costs will be affected by any future restricted stock unit grants and by the separation of an employee from the company who has received restricted stock units that are unvested as of their separation date. There were no modifications to the restricted stock units during fiscal 2012.

Phantom Stock Plan

The company provides a Phantom Stock Plan to provide additional incentive compensation to certain key employees who are not officers of the company. The plan awards phantom stock units to participants who have the right to receive the value of a share of common stock in cash from the company. Participants have no voting or other rights as a shareholder with respect to any common stock as a result of participation in the phantom stock plan. The phantom shares generally have a three or four-year vesting period from the grant date of the award provided the employee remains employed by the company during the vesting period. Participants receive dividend equivalents at the same rate as dividends on the company's common stock.

The following table sets forth a summary of phantom stock activity of the company for fiscal 2012, 2011 and 2010:

	Weighted-average Grant-Date Fair Value		Time Based Shares			Performance Based Shares

Non-Employee Board of Directors Deferred Stock Unit Plan

The company provides a Deferred Stock Unit Plan to its non-employee directors. The plan provides that each non-employee director is granted annually a number of stock units having an aggregate value of $100,000 on the date of grant. Dividend equivalents are paid on the stock units at the same rate as dividends on the company's common stock and are re-invested as additional stock units based upon the fair market value of a share of company common stock on the date of payment of the dividend. A stock unit represents the right to receive from the company the equivalent value of one share of company's common stock in cash. Payment of the value of the stock unit shall be made upon the earlier of the date that is 15 days following the date the participant ceases to be a director for any reason or upon a change of control of the company. The participant can elect to receive five annual installments or a lump sum.

The following table sets forth a summary of deferred stock unit activity of the company for fiscal 2012, 2011 and 2010:

Common Stock Repurchases

In May 2011, the company's Board of Directors replaced its then existing July 2009 share repurchase program with a new $200.0 million repurchase program that is in effect through June 30, 2012. The Board of Directors authorized the company to repurchase shares of its common stock in open-market or privately-negotiated transactions. The company uses its available cash and, when considered advantageous, borrowings under its revolving credit facility, or other borrowings, to fund any share repurchases. The company will evaluate share repurchase opportunities relative to other investment opportunities and in the context of current conditions in the credit and capital markets. At March 31, 2012, $165.0 million authorization remains available to repurchase shares under the May 2011 share repurchase program.

The company's Board of Directors had previously authorized the company in July 2009 to repurchase up to $200.0 million in shares of its common stock in open-market or privately-negotiated transactions. The Board of Directors' authorization for this repurchase program was replaced in May 2011 when the Board of Directors extended the program.

Sale/Leaseback Arrangements

Sale/Leaseback Arrangements [Abstract]

Sale/Leaseback Arrangements

(10) SALE/LEASBACK ARRANGEMENTS

Fiscal 2010 Sale/Leaseback

In June 2009, the company sold five vessels to four unrelated third-party companies, and simultaneously entered into bareboat charter agreements for the vessels with the purchasers. In July 2009, the company sold an additional vessel to an unrelated third-party company, and simultaneously entered into a bareboat charter agreement with that purchaser.

The sale/leaseback transactions resulted in proceeds to the company of approximately $101.8 million and a deferred gain of $39.6 million. The aggregate carrying value of the six vessels was $62.2 million at the dates of sale. The leases on the five vessels sold in June 2009 will expire June 30, 2014, and the lease on the vessel sold in July 2009 will expire July 30, 2014. The company is accounting for the transactions as sale/leaseback transactions with operating lease treatment and expenses lease payments over the five year charter hire operating lease terms.

Under the sale/leaseback agreements, the company has the right to either re-acquire the six vessels at 75% of the original sales price or cause the owners to sell the vessels to a third-party under an arrangement where the company guarantees approximately 84% of the original lease value to the third party purchaser. The company also has the right to re-acquire the vessels prior to the end of the charter term with penalties of up to 5% assessed if purchased in years one and two of the five year lease. The company will recognize the deferred gain as income if it does not exercise its option to purchase the six vessels at the end of the operating lease term. If the company exercises its option to purchase these vessels, the deferred gain will reduce the vessels' stated cost after exercising the purchase option.

Fiscal 2006 Sale/Leaseback

In March 2006, the company entered into agreements to sell five of its vessels that were under construction at the time to Banc of America Leasing & Capital LLC (BOAL&C), an unrelated third party, for $76.5 million and simultaneously entered into bareboat charter agreements with BOAL&C upon the vessels' delivery to the market. Construction on these five vessels was completed at various times between March 2006 and March 2008, at which time the company sold the respective vessels and simultaneously entered into bareboat charter agreements.

The company accounted for all five transactions as sale/leaseback transactions with operating lease treatment. Accordingly, the company did not record the assets on its books and the company is expensing periodic lease payments.

The bareboat charter agreements on the first two vessels expire in calendar year 2014 unless extended. The company has the option to extend the respective bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2017. The bareboat charter agreements on the third and fourth vessels expire in 2015 and the company has the option to extend the bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2018. The bareboat charter agreement on the fifth vessel expires in 2016. The company has the option to extend the bareboat charter agreements three times, each for a period of 12 months, which would provide the company the opportunity to extend the operating leases through calendar year 2019. At the end of the basic term (or extended option periods), the company has an option to purchase each of the vessels at its then fair market value or to redeliver the vessel to its owner. The company may also purchase each of the vessels at their fixed amortized values, as outlined in the bareboat charter agreements, at the end of the fifth year, and again at the end of the seventh year, from the commencement dates of the respective charter agreements.

Future Minimum Lease Payments

As of March 31, 2012, the future minimum lease payments for the vessels under the operating lease terms are as follows:

[1] Marine support services are conducted worldwide with assets that are highly mobile. Revenues are principally derived from offshore service vessels, which regularly and routinely move from one operating area to another, often to and from offshore operating areas in different continents. Because of this asset mobility, revenues and long-lived assets attributable to the company's international marine operations in any one country are not material. Equity in net assets of non-U.S. subsidiaries is $3.1 billion, $2.8 billion and $2.4 million at March 31, 2012, 2011 and 2010, respectively. Identifiable assets include accounts receivable and other balances denominated in currencies other than the U.S. dollar, which aggregate approximately $0.3 million, $0.5 million and $1.4 million at March 31, 2012, 2011, and 2010, respectively. These amounts are subject to the usual risks of fluctuating exchange rates and government-imposed exchange controls.

Goodwill [Abstract]

Goodwill

(15) GOODWILL

The company tests goodwill for impairment annually at the reporting unit level using carrying amounts as of December 31 or more frequently if events and circumstances indicate that goodwill might be impaired. The company uses the two-step method for evaluating goodwill for impairment as prescribed in ASC 350, Intangibles-Goodwill and Other (ASC 350). Step one involves comparing the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit's carrying amount is greater than the fair value, the second step must be completed to measure the amount of impairment, if any. Step two involves calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible assets, excluding goodwill, of the reporting unit from the fair value of the reporting unit as determined in step one. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss is recognized equal to the difference. The company performed its annual impairment test as of December 31, 2010 on its then existing International and United States reporting units, and the test determined there was no goodwill impairment.

As discussed in Note (14), the company changed its reportable segments during the quarter ended September 30, 2011 from International and United States to Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The company performed an interim goodwill impairment assessment prior to changing its reportable segments and determined there was no goodwill impairment.

Goodwill of approximately $49.4 million historically assigned to the United States segment was assigned to the Americas segment. Goodwill of approximately $279.4 million historically assigned to the International segment was allocated among the new reportable segments based on their relative fair values.

The company also performed an interim goodwill impairment assessment on the new reporting units using September 30, 2011 carrying values and determined on the basis of the step one impairment test that the carrying value of its Middle East/North Africa unit exceeded its fair value thus triggering the second step of the analysis as prescribed by ASC 350. An estimated goodwill impairment charge of $30.9 million was recorded during the quarter ended September 30, 2011. Step two of the assessment was completed during the quarter ended December 31, 2011 and there was no further adjustment to goodwill.

Goodwill by reportable segment at March 31, is as follows:

(In thousands)	2012		2011
Americas	$	114,237		114,237
Asia/Pacific		56,283		56,283

Revolving Credit and Term Loan Agreement

Borrowings under the company's $575 million amended and restated revolving credit facility ("credit facility"), which includes a $125 million term loan ("term loan") and a $450 million revolving line of credit ("revolver") bear interest at the company's option at the greater of (i) prime or the federal funds rate plus 0.50 to 1.25%, or (ii) Eurodollar rates plus margins ranging from 1.50 to 2.25%, based on the company's consolidated funded debt to total capitalization ratio. Commitment fees on the unused portion of the facilities range from 0.15 to 0.35% based on the company's funded debt to total capitalization ratio. The facilities provide for a maximum ratio of consolidated debt to consolidated total capitalization of 55% and a minimum consolidated interest coverage ratio (essentially consolidated earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four prior fiscal quarters to consolidated interest charges for such period) of 3.0. All other terms, including the financial and negative covenants, are customary for facilities of its type and consistent with the prior agreement in all material respects. The company's credit facility matures in January 2016.

In July 2011, the credit facility was amended to allow 365 days (originally 180 days) from the closing date ("delayed draw period") to make multiple draws under the term loan. In January 2012, the company elected to borrow the entire $125 million available under the term loan facility and used the proceeds to fund working capital and for general corporate purposes. Principal repayments on the term loan borrowings are payable in quarterly installments beginning in the quarter ending September 30, 2013 in amounts equal to 1.25% of the total outstanding borrowings as of July 26, 2013.

The company has $125 million in term loan borrowings outstanding at March 31, 2012, and the entire $450 million of the revolver was available, with no outstanding borrowings at March 31, 2012. There were no outstanding borrowings at March 31, 2011 under any of the credit facilities.

Senior Debt Notes

The determination of fair value includes an estimated credit spread between our long term debt and treasuries with similar matching expirations. The credit spread is determined based on comparable publicly traded companies in the oilfield service segment with similar credit ratings (Level 2 inputs as defined in the accounting guidance).

August 2011 Senior Notes

The notes may be retired before their respective scheduled maturity dates subject only to a customary make-whole provision. The terms of the notes require that the company maintain a minimum ratio of debt to consolidated total capitalization that does not exceed 55%.

Included in accumulated other comprehensive income at March 31, 2012 and 2011, is an after-tax loss of $3.3 million ($5.1 million pre-tax), and $3.8 million ($5.8 million pre-tax), respectively, relating to the purchase of interest rate hedges, which are cash flow hedges, in July 2010 in connection with the September 2010 senior notes offering. The interest rate hedges settled in August 2010 concurrent with the pricing of the senior unsecured notes. The hedges met the effectiveness criteria and their acquisition costs are being amortized over the term of the individual notes matching the term of the hedges to interest expense.

July 2003 Senior Notes

In July 2003, the company completed the sale of $300 million of senior unsecured notes. A summary of the aggregate amount of remaining senior unsecured notes that were issued in July 2003 and outstanding at March 31, are as follows:

(In thousands, except weighted average data)		2012		2011
Aggregate debt outstanding	$	235,000		275,000
Weighted average remaining life in years		1.4		2.1
Weighted average coupon rate on notes outstanding		4.43	%	4.39	%
Fair value of debt outstanding		240,585		285,478

The multiple series of notes were originally issued with maturities ranging from seven to 12 years. These notes can be retired in whole or in part prior to maturity for a redemption price equal to the principal amount of the notes redeemed plus a customary make-whole premium. The terms of the notes provide for a maximum ratio of consolidated debt to total capitalization of 55%.

Notes totaling $40 million matured in July 2011 but were not classified as current maturities of long-term debt because the company had the ability to fund this maturity with its credit facility. Notes totaling $60.0 million will mature in July 2012 but are not classified as current maturities of long-term debt because the company has the ability, if necessary, to fund this maturity with its credit facility.

Segment Information, Geographical Data And Major Customers

(14) SEGMENT INFORMATION, GEOGRAPHICAL DATA AND MAJOR CUSTOMERS

The company follows the disclosure requirements of ASC 280, Segment Reporting. Operating business segments are defined as a component of an enterprise for which separate financial information is available and is evaluated by the chief operating decision maker in deciding how to allocate resources and in assessing performance.

During the quarter ended September 30, 2011, our International and United States segments were reorganized to form four new operating segments. We now manage and measure our business performance in four distinct operating segments which are based on our geographical organization: Americas, Asia/Pacific, Middle East/North Africa, and Sub-Saharan Africa/Europe. The new segments are reflective of how the company's chief operating decision maker (CODM) reviews operating results for the purposes of allocating resources and assessing performance. The company's CODM is its Chief Executive Officer. Moreover, management decided to reorganize its reporting segments because the company's Sub-Saharan Africa/Europe and Latin American business regions gained greater significance as a percentage of consolidated revenues and operating profit, while our former United States segment decreased in its significance to consolidated revenues and operating profit. Prior period disclosures have been adjusted to reflect the change in reportable segments.

The following table provides a comparison of revenues, vessel operating profit, depreciation and amortization, and additions to properties and equipment for the years ended March 31. Vessel revenues and operating costs relate to vessels owned and operated by the company while other operating revenues relate to the activities of the company's shipyards, brokered vessels and other miscellaneous marine-related businesses.

(A) Marine support services are conducted worldwide with assets that are highly mobile. Revenues are principally derived from offshore service vessels, which regularly and routinely move from one operating area to another, often to and from offshore operating areas in different continents. Because of this asset mobility, revenues and long-lived assets attributable to the company's international marine operations in any one country are not material. Equity in net assets of non-U.S. subsidiaries is $3.1 billion, $2.8 billion and $2.4 million at March 31, 2012, 2011 and 2010, respectively. Identifiable assets include accounts receivable and other balances denominated in currencies other than the U.S. dollar, which aggregate approximately $0.3 million, $0.5 million and $1.4 million at March 31, 2012, 2011, and 2010, respectively. These amounts are subject to the usual risks of fluctuating exchange rates and government-imposed exchange controls.

(B) Included in Corporate are additions to properties and equipment relating to vessels currently under construction which have not yet been assigned to a non-corporate reporting segment as of the dates presented.

(C) Included in Corporate are vessels currently under construction which have not yet been assigned to a non-corporate reporting segment. The vessel construction costs will be reported in Corporate until the earlier of the vessels being assigned to a non-corporate reporting segment or the vessels' delivery. At March 31, 2012, 2011 and 2010, $249.4 million, $355.3 million and $256.3 million, respectively, of vessel construction costs are included in Corporate.
